  When a medal is inserted by the player and the start lever is operated, one value (hereinafter, random number value) is extracted from a random number within a predetermined numerical value range (for example, 0 to 65535).

  The internal lottery means performs a lottery based on the extracted random number value and determines an internal winning combination. This internal lottery means is carried out by a main control circuit described later. By determining the internal winning combination, a combination of symbols permitted to be displayed along a winning determination line described later is determined. In addition, the types of symbol combinations include those related to “winning” in which a bonus such as payout of medals, activation of replays, activation of bonuses, etc. are given to a player, and those relating to other so-called “losing”. Is provided.

  Further, when the start lever is operated, rotation of the plurality of reels is performed. Thereafter, when the stop button corresponding to the predetermined reel is pressed by the player, the reel stop control means performs control to stop the rotation of the corresponding reel based on the internal winning combination and the timing at which the stop button is pressed. Do. This reel stop control means is carried out by a main control circuit described later.

  In the pachislot, basically, control for stopping the rotation of the relevant reel is performed within a specified time (190 msec or 75 msec) from when the stop button is pressed. In the present embodiment, the number of symbols that move with the rotation of the reel within the specified time is referred to as “the number of sliding pieces”. If the specified period is 190 msec, the maximum number of sliding pieces is determined to be four symbols, and if the specified period is 75 msec, the maximum number of sliding pieces is determined to be one symbol.

  When the internal winning combination that permits the display of the combination of the symbols related to the winning is determined, the reel stop control unit normally changes the combination of the symbols to the winning determination line within a specified time of 190 msec (for four frames of the symbol). The rotation of the reel is stopped so as to be displayed along as much as possible. In addition, for example, during the operation of a challenge bonus (CB), which is a second type special accessory, and a middle bonus (MB) for continuously operating the CB, the reel stop control means controls one or more reels. The rotation of the reel is stopped so that the combination of the symbols is displayed as much as possible along the winning determination line within the time 75 msec (for one frame of the symbol). Further, the reel stop control means uses various specified times corresponding to the gaming state to rotate the reels so that a combination of symbols whose display is not permitted by the internal winning combination is not displayed along the winning determination line. Stop.

  When the rotations of the plurality of reels are all stopped, the winning determination unit determines whether the combination of the symbols displayed along the winning determination line is related to the winning. This winning determination means is carried by a main control circuit described later. When the prize determining means determines that the prize is related to a prize, a privilege such as a medal payout is given to the player. In the pachislot, the above-described series of flows is performed as one game.

  Further, in the pachislot, in the above-described series of flows, display of an image performed by a display device such as a liquid crystal display device, output of light performed by various lamps, output of sound performed by a speaker, or a combination thereof is used. Various effects are performed.

  When the start lever is operated, an effect random number value (hereinafter, effect random number value) is extracted separately from the random number value used for determining the internal winning combination described above. When the effect random number value is extracted, the effect content determination means randomly determines the effect to be executed this time from among a plurality of types of effect contents associated with the internal winning combination. This effect content determination means is carried by a sub-control circuit described later.

  When the content of the effect is determined, the effect executing means executes the effect corresponding to each opportunity such as when the rotation of the reels is started, when the rotation of each reel is stopped, and when the winning is determined. In this way, in the pachislot, by executing the effect contents associated with the internal winning combination, the player has an opportunity to know or predict the determined internal winning combination (in other words, a combination of symbols to be aimed). Provided to improve the interest of the player.

When the medal moving on the medal rail 210 satisfies the standard size, the select plate 207 at the guide position contacts the upper part of the medal moving and guides the medal to the medal exit 204c (see FIG. 8). When the medal is guided by the select plate 207, the medal pressure 213 is pressed forward of the pachislot 1.
Are omitted.

  On the other hand, even if the medals moving on the medal rail 210 satisfy the standard size, the select plate 207 at the discharge position sends the medal to the medal exit because the distance between the plate body 224 and the medal rail 210 is large. The user cannot be guided to the section 204c (see FIG. 8). The medals are pushed out by a medal pressure 213, an after-medal pressure 218 protruding from the upper exposure hole 219, or a medal stopper 227 protruding from the lower exposure hole 220, and are discharged toward the cancel shooter 206.

  In the present embodiment, the select plate 207 is normally positioned at the guide position. However, under a predetermined condition (for example, when inserting a predetermined number of medals, when an error occurs, at the start of a game, etc.), the select plate 207 is positioned at the discharge position. It is positioned.

  When the medal moving on the medal rail 210 has a smaller diameter than the standard size, even if the select plate 207 is at the guide position, the medal is not guided by the select plate 207 but is pushed out by the medal pressure 213 and the cancel shooter 206 It is discharged toward.

The main CPU 93 and the above-described hopper device 51 constitute a game medium payout device of the present invention.

  The main ROM 94 includes a control program executed by the main CPU 93 (for example, a program for executing the above-described internal lottery process), a data table, and various control commands (commands) to the sub control circuit 101. Data and the like are stored. The main RAM 95 is provided with a storage area for storing various data such as an internal winning combination determined by executing the control program.

  The main CPU 93 is connected to a clock pulse generation circuit 96, a frequency divider 97, a random number generator 98, and a sampling circuit 99. Clock pulse generation circuit 96 and frequency divider 97 generate clock pulses. The main CPU 93 executes a control program based on the generated clock pulse. The random number generator 98 generates random numbers in a predetermined range (for example, 0 to 65535). The sampling circuit 99 extracts one value from the generated random numbers.

  After detecting the reel index, the main CPU 93 counts the number of times a pulse has been output to the stepping motor of each of the reels 3L, 3C, 3R. Thereby, the main CPU 93 manages the rotation angles of the reels 3L, 3C, 3R (mainly how many symbols the reel has rotated). The reel index is information indicating that the reel has made one rotation. The reel index is provided, for example, at a predetermined position on each of the reels 3L, 3C, 3R and an optical sensor having a light emitting unit and a light receiving unit. It is detected by a reel position detecting unit (not shown) having a detecting piece interposed therebetween.

  Here, the management of the rotation angles of the reels 3L, 3C, 3R will be specifically described. The number of pulses output to the stepping motor is counted by a pulse counter provided in the main RAM 95. Each time a pulse counter outputs a predetermined number of pulses (for example, 16 times) necessary for rotation of one symbol, the symbol counter provided in the main RAM 95 is incremented by one. The symbol counter is provided for each of the reels 3L, 3C, 3R. The value of the symbol counter is cleared when a reel index is detected by a reel position detector (not shown).

  In other words, in the present embodiment, by managing the symbol counter, it is possible to manage how many symbols have been rotated since the reel index was detected. Therefore, the position of each symbol on each of the reels 3L, 3C, 3R is detected based on the position where the reel index is detected.

  As described above, when the maximum number of sliding pieces is set to four symbols, when the left stop button 19L is pressed, the symbol of the left reel 3L in the middle of the reel display window 4 and the four symbols are displayed. Each symbol within the range up to the previous symbol is a symbol that can be stopped in the middle of the reel display window 4.

<Sub-control circuit>
Next, the sub control circuit 101 including the sub control board 72 will be described with reference to FIG. FIG. 12 is a block diagram illustrating a configuration example of the sub-control circuit 101 of the pachi-slot 1.

Further, a drawing control task for controlling display of an image by the liquid crystal display device 11 (see FIG. 2) based on the determined effect contents, a lamp control task for controlling light output by a light source such as an LED 85, and speakers 58, 64, and 65L. , 65R, etc., and a voice control task for controlling the output of sound from a speaker.

  The data storage area includes a storage area for storing various data tables, a storage area for storing effect data constituting each effect content, and a storage area for storing animation data related to video creation. In addition, a storage area for storing sound data relating to BGM and sound effects, a storage area for storing lamp data relating to a light on / off pattern, and the like are included.

  The sub RAM 103 includes a sub DRAM (Dynamic Random Access Memory) 103a and a sub SRAM (Static Random Access Memory) 103b. The sub DRAM 103a is a work RAM as a volatile storage unit. The sub SRAM 103b is a backup RAM as a non-volatile storage unit that is backed up by a backup power supply.

  The sub DRAM 103a is not allocated to a storage area for registering the determined effect contents and effect data, a storage area for storing various data such as an internal winning combination transmitted from the main control circuit 91, and other backup areas. A storage area for storing data (data that can be erased when the power is off) is provided.

  The backup area configured by the sub SRAM 103b is capable of storing data held at the time of power failure when the power failure occurs. Data is available. Further, for example, various information received from the medal selector 201 or the 24h door monitoring unit 63 is stored.

  The sub CPU 102, the rendering processor 104, the drawing RAM (including the frame buffer) 105, and the driver 106 create a video according to the animation data specified by the effect contents, and display the created video on the liquid crystal display device 11.

Further, the sub CPU 102 controls turning on and off of the light source such as the LED 85 according to the lamp data specified by the effect contents.

  A sub RTC (Real Time Clock) 108 is a clock circuit, and outputs information indicating the current time, that is, information indicating the year, month, day, hour, minute, second, and day of the week in response to a request from the sub CPU 102.

<Configuration of medal selector>
Next, the configuration of the medal selector 201 will be described with reference to FIGS. FIG. 13 is a block diagram illustrating a circuit configuration example of the medal selector 201. FIG. 14 is a block diagram illustrating a circuit configuration example of the control LSI 234.

  As shown in FIG. 13, the medal selector 201 includes a camera unit 209, a medal solenoid 208, and a double photo sensor 272. The medal selector 201 is connected to the main control board 71 via a door relay terminal plate 68. The medal selector 201 is connected to the sub relay board 61 by a cable 280, and is connected to the sub control board 72 via the sub relay board 61. That is, the medal selector 201 is electrically connected to the main control circuit 91 and the sub control circuit 101.

  The main control circuit 91 can set the medal solenoid 208 of the medal selector 201 to an ON state or an OFF state. That is, the main control circuit 91 can move the select plate 207 to the guide position or the discharge position.

  Specifically, when the pachislo 1 is in a state where medals can be inserted, the main control circuit 91 outputs a medal insertion signal indicating that insertion is possible. When the pachislot 1 is not in a state where medals can be inserted, the main control circuit 91 outputs a medal insertion signal indicating that insertion is not possible. Here, "to output a medal insertion signal indicating that insertion is possible" means that a signal line between devices (medal solenoid 208 in the present embodiment) connected to the main control circuit 91 is set to an ON state. is there. “To output a medal insertion signal indicating that the insertion is impossible” means to set the signal line between the devices (the medal solenoid 208 in the present embodiment) connected to the main control circuit 91 to the OFF state. . When detecting that the signal line between the main control circuit 91 and the medal solenoid 208 has been turned ON, the medal solenoid 208 sets itself to the ON state. When detecting that the signal line between the main control circuit 91 and the medal solenoid 208 has been turned off, the medal solenoid 208 sets itself to the off state.

  The double photo sensor 272 of the medal selector 201 is connected to the main control board 71 via the door relay terminal plate 68. The double photo sensor 272 includes a first photo sensor 273 and a second photo sensor 274.

  As shown in FIG. 8, the first photo sensor 273 is provided near the medal exit portion 204c in the base plate portion 204 of the medal selector 201. The first photo sensor 273 includes a photodiode (see FIG. 7) embedded on the medal rail 210 of the base plate portion 204, a light emitter (see FIG. 7) that irradiates the photodiode with light (infrared light), Having. The photodiode and the light emitter face each other with a distance equal to or greater than the thickness of the medal, and when the select plate 207 is at the guide position, the medal moving on the medal rail 210 can pass between the photodiode and the light emitter. It has become.

  The luminous body always emits a predetermined amount of light. When the photodiode receives a predetermined amount of light or more from the light emitter, the first photosensor 273 outputs a high-level signal. On the other hand, when the amount of light received by the photodiode is less than the predetermined amount, the first photosensor 273 outputs a low-level signal (medal detection signal). Therefore, when the light of the light emitter is blocked when the medal passes between the photodiode and the light emitter, the first photosensor 273 outputs a medal detection signal.

  The second photo sensor 274 moves on the medal rail 210 closer to the medal exit portion 204c of the base plate portion 204 of the medal selector 201 and closer to the first photo sensor 273 than the first photo sensor 273. It is provided on the downstream side in the moving direction of the medals. Note that the other points are the same as those of the first photosensor 273, and a description thereof will be omitted.

  In the present embodiment, the first photosensor 273 and the second photosensor 274 constituting the double photosensor 272 are configured such that a medal passes between the photodiode and the light emitter to block light of the light emitter. In the above, the mode in which the shielded sensor system for detecting the passing object (that is, the detection system for detecting when the state of the photodiode changes from the on state to the off state) is described. However, the mode of detecting medals with a photodiode is not limited to this. For example, a so-called reflection-type sensor system is used in which a photodiode and a light emitter are arranged on the left and right or up and down, and the passage of the medal is detected by the photodiode receiving light reflected by the medal passing through the light of the light emitter. May be. In addition, the first photosensor 273 may be a shield type, the second photosensor 274 may be a reflection type, or a combination of the two types may be appropriately selected and employed depending on the position where the photodiode is arranged. Good.

  As described above, the first photo sensor 273 is provided near the medal exit portion 204c, and the second photo sensor 274 is provided downstream of the first photo sensor 273 on the medal rail 210. For this reason, the first photosensor 273 and the second photosensor 274 detect the medal that moves to the medal exit 204c (see FIG. 8) when the select plate 207 is in the guide position, but the select plate 207 is in the discharge position. No medals guided to the medal shoot 202 (see FIG. 6) are detected.

  The medal detection signals output from the first photo sensor 273 and the second photo sensor 274 are input to the main control board 71 (main control circuit 91) via the door relay terminal plate 68. After the main CPU 93 (see FIG. 11) of the main control board 71 detects the medal detection signal input from the first photo sensor 273, the main CPU 93 outputs the medal detection signal input from the second photo sensor 274 within a predetermined time. Upon detection, the number of inserted medals is incremented by one to the value of a inserted number counter, which is a counter provided for the main CPU 93 to count. If the value of the inserted number counter is the maximum value (for example, 3), the number of credited medals is incremented by 1 to the value of the credit counter, which is a counter provided for the main CPU 93 to count.

  When the credit counter has the maximum value (for example, 50), the main control circuit 91 sets the medal solenoid 208 of the medal selector 201 to the OFF state. As a result, the select plate 207 (see FIG. 8) is positioned at the “discharge position”, medals cannot be inserted, and medals inserted after the credit counter reaches the maximum value are stored in the medal shoot 202 (see FIG. 6). It is guided and discharged to the medal tray unit 34 from the medal payout exit 32 (see FIG. 2).

  The main control circuit 91 sets the medal solenoid 208 of the medal selector 201 to the OFF state even after the start lever 23 is operated by the player in the unit game.

  When the main CPU 93 receives a medal detection signal in the order of the medal detection signal input from the second photo sensor 274 and the medal detection signal input from the first photo sensor 273, the medal moves on the medal rail 210. It is detected that a so-called backward error has occurred, which moves in a moving direction different from (reverse to) the proper moving direction.

  Further, even if a certain period of time has elapsed since the main CPU 93 detected the medal detection signal, the medal detection signal continues to be output from one or both of the first photosensor 273 and the second photosensor 274. In a case or when a medal detection signal from the second photo sensor 274 cannot be detected even after a certain period of time has elapsed since the detection of the medal detection signal from the first photo sensor 273, the medal stays on the medal rail 210, so-called It detects that a medal jam error has occurred.

  When the main control circuit 91 (main CPU 93) detects a backward error or a medal jam error, the game is forcibly interrupted, and the 7-segment display 24 (see FIG. 2) displays an error code corresponding to the detected error. Is displayed, and an error command corresponding to the content of the detected error is transmitted to the sub-control circuit 101 to notify the error via the sub-control circuit 101. For example, when an error screen indicating the content of an error is displayed on the liquid crystal display device 11 or when a sub 7-segment display (not shown) for controlling the display by the sub-control circuit 101 is provided, a predetermined Or display.

  The sub-control circuit 101 receives, from the control LSI 234 of the medal selector 201, the result of the color determination, the result of the engraving determination, and various signals and commands.

  The camera unit 209 includes a control LSI 234, a CMOS image sensor 232, and an LED 233. The control LSI 234 of the camera unit 209 includes an ASIC (Application Specific Integrated Circuit), and is electrically connected to the CMOS image sensor 232 and the LED 233. The control LSI 234 controls the light emission of the LED 233. Further, the control LSI 234 determines whether or not the object moving on the medal rail 210 is a regular medal based on the image data output from the CMOS image sensor 232, and sends the determination result from the UART 252 (described later) to the sub relay board. The signal is transmitted to the sub control board 72 (sub control circuit 101) via 61.

  The CMOS image sensor 232 has an exposure time setting mechanism for setting the exposure time (shutter speed) in 1 to 25 steps. The exposure time is set so as to extend by 7 μs for each step up. In the present embodiment, the initial value of the exposure time (the value when the power of the pachislot 1 is turned on) is set to the stage 10, that is, 70 μs. Therefore, in the present embodiment, the exposure time can be set in a range from 70 μs to a maximum of 175 μs (exposure time corresponding to step 25). In the present embodiment, the CMOS image sensor 232 employed is a CMOS image sensor having a resolution of 648 × 488 pixels and a frame rate of 240 fps (Frames Per Second).

  The control LSI 234 is electrically connected to the notification LED 206c via the GPIO 250. The notification LED 206c is turned on and off according to an instruction from the control LSI 234. The control LSI 234 is electrically connected to the initialization switch 206d, the color switch 206e, the engraving switch 206f, and the GPIO 250.

  When the initialization switch 206d is operated (turned on) during energization, the control LSI 234 performs a switch response initialization process (in this embodiment, transmits an encryption key to the medal selector 201). The processing including the processing is referred to as “initialization processing”, and the initialization processing performed in response to the operation of the initialization switch 206d is referred to as “switch response initialization processing” to be distinguished therefrom.) In the switch response initialization process, the control LSI 234 deletes various parameters and templates stored in the SRAM 243 and the flash memory 244 described later, and sets (resets) these to initial values.

  The color switch 206e can be set to an ON / OFF state. When the color switch 206e is set to the ON state, the control LSI 234 validates the color determination, and changes the value of the color determination result included in the determination completion command to “1” (determination OK) or “OK” according to the actual determination result. 0 "(determination NG). On the other hand, when the color switch 206e is set to the OFF state, the control LSI 234 invalidates the color determination and sets the value of the color determination result included in the determination completion command to “1” (determination OK) regardless of the actual determination result. Set to. That is, the color switch 206e is set to an ON state when enabling color determination, and is set to an OFF state when invalidating the color determination.

  The engraving switch 206f can be set to an ON / OFF state. When the engraving switch 206f is set to the ON state, the control LSI 234 validates the engraving determination and sets the value of the engraving determination result included in the determination completion command to “1” (determination OK) or “OK” according to the actual determination result. 0 "(determination NG). On the other hand, when the engraving switch 206f is set to the OFF state, the control LSI 234 invalidates the engraving determination and sets the value of the engraving determination result included in the determination completion command to “1” (determination OK) regardless of the actual determination result. Set to. That is, the marking switch 206f is set to the ON state when making the marking determination valid, and is set to the OFF state when making the marking determination invalid.

  In the present embodiment, the control LSI 234 sets the validity / invalidity of the color determination according to the ON / OFF state of the color switch e when the power is turned on, and also controls the ON / OFF state of the engraving switch f when the power is turned on. To enable / disable stamping judgment. Even if these switches are operated after the power is turned on, the validity / invalidity of the color judgment and the marking judgment set in accordance with the state of the switch at the time of the power on is not changed. The control LSI 234 acquires the ON / OFF state of the initialization switch 206d, the color switch 206e, and the engraving switch 206f at a predetermined cycle (for example, a cycle of 10 msec). This cycle is set shorter than the cycle for transmitting the medal selector no-operation command.

<Configuration of control LSI>
Next, a circuit configuration of the control LSI 234 will be described with reference to FIG.

  The control LSI 234 includes a host controller 241, an image recognition DSP (digital signal processor) circuit 242, an SRAM (Static Random Access Memory) 243 to which a backup power supply (not shown) is connected, a flash memory 244, and an ISP (Image Signal Processing) circuit 245.

  The control LSI 234 includes an ISI (Image Sensor Interface) circuit 251. The ISI circuit 251 is electrically connected to the CMOS image sensor 232 and the ISP circuit. The ISI circuit 251 converts the image data transmitted from the CMOS image sensor 232 by the LVDS (Low voltage differential signaling) method into an RGB Bayer image and outputs the RGB data. At this time, a unique image ID is assigned to the RGB image output from the ISI circuit 251. This image ID is carried over to data after various types of image conversion. For this reason, based on the image ID carried over by the data relating to the various determinations, the respective determination results can be linked. That is, when a medal is shown in the RGB image, these determination results for this medal can be associated.

  When the RGB Bayer image is output from the ISI circuit 251 (the RGB Bayer image is input), the ISP circuit 245 outputs a VSYNC (Vertical Synchronization) interrupt signal to the host controller 241. Further, the ISP circuit 245 performs an image correction process of performing a lens distortion correction process and a projective transformation (homography) process on the RGB Bayer image output from the ISI circuit 251.

  The color recognition circuit 247 performs a color determination process based on the hue and saturation in the HSV image data output from the ISP circuit 245. The color determination process includes a medal detection process, a threshold value determination process, a saturation / hue multiplication process, a color template generation process, and a color template comparison process.

  The medal counting circuit 246 performs a counting process based on the grayscale image data output from the ISP circuit 245. The counting process includes a medal image determination process, a medal position detection process, and an order determination process.

  The fisheye correction scaler circuit 248 obtains grayscale image data from the SRAM 243 and performs a fisheye correction process for correcting the obtained grayscale image data with fisheye.

  In the preprocessing, the image recognition DSP circuit 242 acquires reduced image data (reduced image data reduced to 1/4 in this embodiment) from the SRAM 243, and detects a circular region from the acquired reduced image data. The processing and the non-linear diffusion filter processing are performed to create an edge image and perform a filter processing for storing the image in the SRAM 243. Further, the image recognition DSP circuit 242 performs various determination processes. In the present embodiment, the image data reduced to 1/4 is used. However, the present invention is not limited to this, and a setting for selecting the reduced image data to be used is stored in the flash memory 244. Thus, the image data reduced to 1/2 or the image data reduced to 1/8 may be selected.

  The image recognition accelerator circuit 249 performs processing related to the gradient average image data, processing related to the edge gradient image, and fast Fourier transform (hereinafter sometimes referred to as “FFT transformation”). Further, the image recognition accelerator circuit 249 performs a template generation process for creating various templates used for the marking determination process.

  The GPIO 250 is a device for input / output between each device connected to the medal selector 201 and the control LSI 234. Further, it is a device for input and output of the control LSI 234 and various devices constituting the medal selector 201.

  The UART 252 is a serial communication device for transmitting and receiving various commands between the medal selector 201 and the sub control circuit 101 including the sub control board 72. In FIG. 14, the illustration of the sub-relay board 61 is omitted.

  The host controller 241 controls each device constituting the control LSI 234, for example, the medal count circuit 246, the color recognition circuit 247, the fisheye correction scaler circuit 248, the image recognition DSP circuit 242, the image recognition accelerator circuit 249, the GPIO 250, and the UART 252. .

  The flash memory 244 includes various devices constituting the control LSI 234, such as a host controller 241, an image recognition DSP circuit 242, a fisheye correction scaler circuit 248, and an image recognition accelerator circuit 249. Data is stored. Further, the flash memory 244 is provided with an area for storing the value of the above-described exposure time step.

<Configuration of door monitoring unit (24h door monitoring unit)>
Next, the 24h door monitoring unit 63 will be described with reference to FIG. FIG. 15 is a block diagram illustrating a configuration example of the 24h door monitoring unit 63.

  As shown in FIG. 15, the 24h door monitoring unit 63 includes a control LSI 300, an RTC (Real Time Clock) 301, a battery 302, a ROM 303, a RAM 304, and an EEPROM (registered trademark: Electronically Erasable Programmable Read-Only Memory) 305. ing. The 24h door monitoring unit 63 is electrically connected to the sub control board 72, the door open / close monitoring switch 67, and the power supply board 53b.

  The control LSI 300 controls the operation of the 24h door monitoring unit 63. The control LSI 300 includes a control controller circuit 306, a serial communication circuit 307, a random number generation circuit 308, and an I / O port circuit 309.

  The control controller circuit 306 executes various processes according to a program stored in the ROM 303. The random number generation circuit 308 is configured by a free-run counter (hereinafter, sometimes referred to as “FRC”), and generates a random number by performing a prescribed calculation using a count value acquired from the FRC. The I / O port circuit 309 is connected to the door opening / closing monitoring switch 67, and receives a signal indicating opening / closing of the front door 2b from the door opening / closing monitoring switch 67. Although not shown in FIG. 15, the I / O port circuit 309 receives a signal indicating the opening / closing of the middle door 41 from a door opening / closing monitoring switch that detects the opening / closing of the middle door 41. In the following, description of the process of monitoring the opening / closing history of the middle door 41 will be omitted.

  The serial communication circuit 307 is used when transmitting and receiving commands and data to and from a host device connected to the 24h door monitoring unit 63. Each time the serial communication circuit 307 receives one byte of a command or data from the host device, the control LSI 300 executes, for example, a reception interrupt process. In the present embodiment, the host device includes a computer 400 as an external computer in addition to the sub-control circuit 101 (sub-control board 72).

  FIG. 15 shows an example in which the sub control board 72 as a host device is connected to the 24h door monitoring unit 63. However, the host device connected to the 24h door monitoring unit is not limited to this. For example, when performing various settings of the 24h door monitoring unit 63 during manufacturing or maintenance of the pachislot 1, a setting machine (for example, the computer 400 described above) is connected to the 24h door monitoring unit 63 as a host device. The setting device includes a nonvolatile storage device (such as a hard disk) and a volatile storage device (such as a RAM).

  The battery 302 is composed of, for example, a lithium ion secondary battery. The battery 302 functions as a power source for the 24h door monitoring unit 63 when the pachislot 1 is turned off. For this reason, the 24h door monitoring unit 63 can perform various processes even when the power of the pachislot 1 is turned off. The battery 302 stores power supplied from the power supply board 53b when the power is turned on in the pachislot 1. Although the rechargeable secondary battery is exemplified as the power supply while the pachislot 1 is turned off, the present invention is not limited to this, and a primary battery (for example, a lithium battery or an alkaline manganese dry battery) may be used. .

  The RTC 301 is a clock circuit that outputs information indicating the current time, that is, information indicating the year, month, day, hour, minute, second, and day of the week in response to a request from the control LSI 300. The RTC 301 constitutes monitoring-side clocking means.

The information stored in the EEPROM 305 and the storage location of the information in the EEPROM 305 will be described later with reference to FIG.

  The RAM 304 is composed of a DRAM (Dynamic Random Access Memory) and is used as a work area of the control LSI 300 and a buffer area for communication between the control LSI 300 and a host device. The information stored in the RAM 304 and the storage location of the information in the RAM 304 will be described later with reference to FIG.

<Overview of Functions of the Present Invention>
Next, an outline of each function of the encryption key creation, initialization, and setting reading according to the embodiment of the present invention will be described with reference to FIGS.

  In the present embodiment, the external computer (computer 400) shown in FIG. 16 creates an encryption key file including an encryption key transmitted to the medal selector 201 and the 24h door monitoring unit 63.

  Such creation of the encryption key file by the computer 400 is performed by an encryption key creation tool (encryption key creation program) executed on the computer 400. When creating an encryption key file for the medal selector 201 or an encryption key file for the 24h door monitoring unit 63, the pachislot 1 and the computer 400 do not need to be connected as shown in FIG.

  In the present embodiment, the encryption key transmitted to the medal selector 201 is stored in the medal selector 201, and is used to encrypt data communication between the medal selector 201 and the sub-control circuit 101. The encryption key transmitted to the 24h door monitoring unit 63 is the same as that of the medal selector 201 in that the encryption key is stored in the 24h door monitoring unit 63, but is for executing a privilege command defined for the 24h door monitoring unit 63. This is different from the encryption key transmitted to the medal selector 201 in that the encryption key is used to generate the login password of the token. Therefore, the encryption key transmitted to the 24h door monitoring unit 63 may be described as a “door monitoring key code”.

  In the present embodiment, as shown in FIG. 16, a computer 400 as an external computer is connected to a medal selector 201 and a 24h door monitoring unit 63 incorporated in a gaming machine such as the pachislot 1, respectively. By operating, the initialization process such as transmitting the above-mentioned encryption key to the medal selector 201 and the 24h door monitoring unit 63 can be performed.

  In initialization related to the medal selector 201, an encryption key for encrypting data exchanged between the medal selector 201 and the sub-control circuit 101 is transmitted to the medal selector 201 and stored. In the initialization relating to the 24h door monitoring unit 63, an encryption key (encryption key required for generating a login password) for logging in to the 24h door monitoring unit 63 (necessary for executing a privileged command or the like) or the like is provided. Other various set values are transmitted to the 24h door monitoring unit 63 and stored.

  Such initialization by the computer 400 is performed by an initialization tool (initialization program) executed by the computer 400.

  Furthermore, in the present embodiment, the computer 400 is connected to the 24h door monitoring unit 63, and various setting information and opening / closing history information stored in the 24h door monitoring unit 63 are read to perform diagnosis, display, storage, and the like. A monitoring unit setting reading tool (door monitoring unit setting reading program) is provided.

  In the present embodiment, a general personal computer is used as the computer 400, but various other types of computer devices can be used.

  Also, as shown in FIG. 16, an operation machine 500 can be connected to the computer 400. From the operation machine 500, the above-described medal selector 201 and the encryption key generation of the 24h door monitoring unit 63 can be performed. It is possible to instruct to perform the conversion process, read the setting of the 24h door monitoring unit 63, and the like. The operation machine 500 includes an input device such as a keyboard and a mouse, and a display device. The operation machine 500 is a computer device used for manufacturing and inspecting a game machine at a game machine manufacturing factory or the like. Instructions for each program executed in 400 can be given more efficiently, and the display contents of each program can be displayed in a legible manner (for example, on a large screen).

  When initializing the medal selector 201, the computer 400 and the medal selector 201 are connected via a cable. For example, when the assembly of the pachislot 1 is completed and the medal selector 201 is incorporated in the pachislot 1, the cable 280 (FIG. 13) for connecting the medal selector 201 and the sub relay board 61 (the sub control board 72 and the sub control circuit 101) is provided. Is temporarily removed from the sub-relay board 61 and connected to the computer 400 to enable serial communication between the medal selector 201 and the computer 400. That is, while the medal selector 201 and the computer 400 are connected, the medal selector 201 and the sub relay board 61 (the sub control board 72 and the sub control circuit 101) are not connected.

  Note that the cable 280 can be directly connected to the computer 400 before the medal selector 201 is attached to the pachislot 1. For example, a USB-TTL serial converter cable is connected to an end portion of the cable 280 (the connector portion connected to the sub-relay board 61), and the cable is inserted into a USB terminal of the computer 400 to connect the computer 400 to the computer 400. The medal selector 201 is connected.

  On the other hand, when initializing the 24h door monitoring unit 63 and reading the settings, the computer 400 and the 24h door monitoring unit 63 are connected via a cable. For example, when the assembly of the pachislot 1 is completed and the 24h door monitoring unit 63 is incorporated in the pachislot 1, the cable 320 (see FIG. 15) connecting the 24h door monitoring unit 63 and the sub control board 72 is connected to the sub control board. 72 (the sub-control circuit 101) and temporarily connected to the computer 400 to enable serial communication between the 24h door monitoring unit 63 and the computer 400. That is, while the 24h door monitoring unit 63 and the computer 400 are connected, the 24h door monitoring unit 63 and the sub-control board 72 (sub-control circuit 101) are not connected.

  Note that the cable 320 can be directly connected to the computer 400 before the 24h door monitoring unit 63 is attached to the pachislot 1.

  A system including at least the medal selector 201 of the pachislot 1 and the computer 400 or a system including at least the 24h door monitoring unit 63 of the pachislot 1 and the computer 400 is a game system according to the present invention.

  FIG. 17 is a diagram showing the outline of the function of the present invention in chronological order. The left column shows the flow of processing related to the medal selector 201, and the right column shows the flow of processing related to the 24h door monitoring unit 63.

  First, an encryption key file relating to the medal selector 201 is created by a medal selector encryption key creation tool (program) at a timing before the pachislot 1 according to the present embodiment is assembled. Also, an encryption key file for the 24h door monitoring unit 63 is created by a door monitoring unit encryption key creation tool (program). These encryption key files include an encryption key (may be the login password itself) for generating a login password, but are themselves files encrypted with a predetermined encryption key.

  When the assembling of the pachislot 1 is completed, the above-mentioned encryption key file is first read by the medal selector initialization tool for the medal selector 201 as shown in the left column. Next, the medal selector initialization tool establishes a connection with the medal selector 201. In this case, either of the reading of the encryption key file and the establishment of the connection between the medal selector initialization tool and the medal selector 201 may be performed first.

  Next, the medal selector 201 is initialized by a medal selector initialization tool. More specifically, the medal selector initialization tool decrypts the read encryption key file to obtain the original encryption key, and transmits this to the medal selector 201. Upon receiving the encryption key from the computer 400, the medal selector 201 stores the encryption key as a new secret key in, for example, the flash memory 244. This secret key is used for encrypting transmitted / received data in data communication between the medal selector 201 and the sub control circuit 101.

  Further, when the original encryption key is transmitted to the medal selector 201 by the medal selector initialization tool, the encryption key can be transmitted after being encrypted with another predetermined encryption key.

  On the other hand, when the assembly of the pachislot 1 is completed, as shown in the right column, regarding the 24h door monitoring unit 63, first, the above-mentioned encryption key file is read by the door monitoring unit initialization tool. Next, the door monitoring unit initialization tool establishes a connection with the door monitoring unit 63 for 24h. In this case, either of the reading of the encryption key file and the establishment of the connection between the door monitoring unit initialization tool and the 24h door monitoring unit 63 may be performed first.

  Next, the door monitoring unit initialization tool initializes the 24h door monitoring unit 63 and sets various setting values. More specifically, the door monitoring unit initialization tool decrypts the read encryption key file to obtain the original encryption key, and transmits it to the door monitoring unit 63 for 24h. When receiving the encryption key from the computer 400, the 24h door monitoring unit 63 stores the encryption key as a new secret key (login password) in, for example, the EEPROM 305. This secret key is used in the 24h door monitoring unit 63 as a password for performing login necessary for executing a privileged command or the like. In addition, various setting values are transmitted to the 24h door monitoring unit 63, and the 24h door monitoring unit 63 updates the corresponding settings with the received setting values.

  When the original encryption key and the set value are transmitted to the door monitoring unit 63 for 24h by the door monitoring unit initialization tool, the encryption key and the set value are encrypted with another predetermined encryption key and transmitted. Can be.

  In this example, initialization is performed after the assembly of the pachislot 1 is completed and the medal selector 201 and the 24h door monitoring unit 63 are assembled into the pachislot 1. However, the medal selector 201 and the 24h door monitoring unit 63 are initialized. Are delivered to the assembly plant as assembly parts, so that the above-mentioned initialization can be performed before assembling them into the pachislot.

  FIG. 18 is a diagram showing the outline of the function of the present invention in chronological order. The process of the door monitoring unit setting reading tool for reading the setting of the 24h door monitoring unit 63 and the events related thereto are represented as a flow. I have.

  A typical example of using the door monitoring unit setting reading tool is roughly divided into a case where a pachislot is collected for reuse and a case where a defect has been reported regarding a pachislot from a hall or a business office.

  When a pachislot is collected for reuse, confirm the operation for reuse and check if there is any problem.

  Next, the connection between the computer 400 that executes the door monitoring unit setting reading tool and the 24h door monitoring unit 63 is performed using the cable 320 as described above. In this case, for example, in a factory or an inspection site, the computer 400 is connected to the 24h door monitoring unit 63 attached to the pachislot 1, but the 24h door monitoring unit 63 removed from the pachislot 1 and the computer 400 are connected. May be connected.

  Next, the data stored in the 24h door monitoring unit 63 is read by the door monitoring unit setting reading tool executed by the computer 400. The data read here includes, for example, various setting information and opening / closing history information.

  Here, the door monitoring unit setting reading tool displays the read data and automatically analyzes a defect based on the data. Items that do not satisfy a predetermined condition are displayed in a conspicuous color in the display area. For example, the display area is displayed in a display mode different from the display area related to other normal items.

  Such a pachislot diagnosis by the door monitoring unit setting reading tool is performed not only when a malfunction is actually found in the operation check but also when a malfunction is not found (it has a potential malfunction). Can also be done.

  On the other hand, when a failure is reported from a hall or the like, the pachislot in question can be collected, and the same flow for finding a failure as described above can be executed. However, since it is known that a problem has occurred, the process of finding the problem by checking the operation can be omitted.

  In addition, when a failure is reported from a hall or the like, a route may be considered in which an engineer, a salesperson, or the like goes to the site and investigates a pachislot in question. In this case, the computer 400 is connected to the 24h door monitoring unit 63 attached to a pachislot installed in a hall or the like, and diagnosis is performed by a door monitoring unit setting reading tool. In this case, the computer 400 is, for example, a type of computer such as a portable notebook personal computer.

<Configuration of computer that executes encryption key creation tool, initialization tool, etc.>
Next, an example of a hardware configuration of the computer 400 will be described with reference to FIG. However, the computer 400 in FIG. 19 merely illustrates a typical configuration of a general personal computer. Various other computer devices including a mobile terminal and a dedicated device can be used as the computer 400.

It includes a storage device 413, an external recording medium interface 414, a serial interface 415, an external I / O interface 416, and a bus 417 connecting these components to each other.

  The CPU 401 controls the operation of each component of the computer 400, and controls the execution of various tools (for example, an encryption key creation tool, an initialization tool, a setting reading tool, and the like) under the control of the OS. .

  The RAM 402 temporarily stores programs for executing the processes executed by the CPU 401 and data used during the execution of the programs. The ROM 403 stores programs executed when the computer 400 is activated.

  The network interface 404 is an interface for connecting to the network 420. The network 420 is a network including the Internet, for example.

  The audio control unit 405 controls the microphone 406 and the speaker 407 to control the input and output of sound. The display controller 408 is a dedicated controller for actually processing a drawing command issued by the CPU 401. The display 409 is a display device including, for example, an LCD.

  The input device interface 410 receives a signal input from the keyboard 411 or the mouse 412 and transmits a predetermined command to the CPU 401 according to the signal pattern.

  The external storage device 413 is, for example, a storage device such as a hard disk or a semiconductor memory, in which the programs described above and data related to these programs are recorded.

  The external recording medium interface 414 accesses the external recording medium 430 and reads data recorded therein. The external recording medium 430 is, for example, a portable flash memory. A program that is executed by the CPU 401 and realizes each function of the present invention can be provided from the external recording medium 430 via the external recording medium interface 414. As another distribution form of the program for realizing each function of the present invention, a route that is stored in the external storage device 413 or the RAM 402 from a predetermined server on the network via the network 420 and the network interface 404 is used. Etc. are also conceivable.

  Further, the encryption key file of the present invention can be output and stored in a storage medium such as the external storage device 413 or the external recording medium 430.

  The serial interface 415 is connected to the medal selector 201 via the cable 280, and controls data transmission / reception for initialization. The serial interface 415 is connected to the 24h door monitoring unit 63 via the cable 320, and controls data transmission and reception for initialization and setting reading.

  The external I / O interface 416 is connected to the operation machine 500 described above, receives inputs for various tools executed by the computer 400 from an input device of the operation machine 500, and displays display data of the various tools on the display of the operation machine 500. It controls the transmission and reception of various data such as output to the device.

<GUI of the medal selector encryption key creation tool>
Next, a GUI (Graphical User Interface) of a medal selector encryption key creation tool (program) for creating an encryption key to be transmitted to the medal selector 201 will be described with reference to FIG. 20 and FIG.

  The medal selector encryption key creation tool is executed in the computer 400 as described above, and the screen of the tool is displayed on the display 409 of the computer 400, and inputs and instructions are performed using the keyboard 411, the mouse 412, and the like. Will be

  FIG. 20A shows an encryption key creation screen 501 of the medal selector encryption key creation tool. The encryption key creation screen 501 includes a creation display unit 502 controlled to be displayed on the front by selecting a creation tab. The creation display unit 502 includes an encryption key input unit 503 and an initialization vector display unit. 504, a checksum display unit 505, a creation date and time display unit 506, and a creation instruction button 507 are shown. FIG. 20A shows an encryption key creation screen 501 before an encryption key is input.

  FIG. 20B shows an encryption key creation screen 501 similar to that shown in FIG. 20A. Here, after the user inputs the encryption key to encryption key input section 503, the encryption key input section This is a state where values are displayed on the 503 and the initialization vector display unit 504, respectively. Here, the user presses the creation instruction button 507 with the mouse 412 (arrow 508) to instruct creation of an encryption key file.

  When inputting the encryption key to the encryption key input unit 503, the user inputs a value of 32 digits (16 bytes, 128 bits) in, for example, hexadecimal characters to the encryption key input unit 503. The key manager sets one encryption key for each or a group of the medal selectors 201, and stores the encryption key separately, for example, in the form of a text file or the like. Alternatively, a text file storing the encryption key can be dragged and dropped (or text copied and pasted) into the encryption key input unit 503 to input a 32-digit number.

  In response to the input of the encryption key to the encryption key input unit 503, the initialization vector display unit 504 displays a randomly generated value in, for example, 32 hexadecimal characters (16 bytes, 128 bits). In FIG. 20B, for convenience, the hexadecimal notation character “F” is displayed on the encryption key input unit 503 and the initialization vector display unit 504, but the encryption key input unit 503 and the initialization vector display unit 504 display The input hexadecimal notation character may be displayed as it is, or may be hidden by a character such as "*" together with the input.

  Here, when the user presses the creation instruction button 507, a checksum for error detection calculated based on the encryption key and the initialization vector is calculated and displayed on the checksum display unit 505, and the encryption is performed. Create a key file. When the creation of the encryption key file is completed, a message to the effect that the creation of the encryption key file has been completed may be displayed in a predetermined area of the encryption key creation screen 501. In FIG. 20B, the creation date and time are not displayed on the creation date and time display unit 506, but the creation date and time may be displayed on the creation date and time display unit 506 when the encryption key file is created.

  The created encryption key file is an encryption key for creating an encryption key file internally held by the medal selector encryption key creation tool (or stored in a predetermined storage means). It contains encrypted data. The encryption key file is stored in a storage unit (external storage device 413) of the computer 400 or the like. Here, for example, the encryption method of the encryption key file is AES, the block size is 128 bits, the encryption key length is 128 bits, and the block encryption mode is CBC mode. For example, the initialization vector is randomly created when the encryption key file is created, and is encrypted together with the encryption key in a positional relationship arranged at the head of the encryption key. The encryption key file is created in a predetermined storage format (for example, an XML file format), and the encryption key file includes the above-described checksum value and creation date and time.

  FIG. 21 shows an encryption key reading screen 511 of the medal selector encryption key creation tool. The encryption key reading screen 511 includes a reading display unit 512 controlled to be displayed on the foreground by selecting a creation tab. The reading display unit 512 includes an encryption key display unit 513, an initialization vector display unit. 514, a checksum display section 515, a creation date and time display section 516, and a read instruction button 517 are shown. FIG. 21 shows that when the read instruction button 517 is pressed with the mouse 412 (arrow 518) and the name of the encryption key file to be read is specified, the specified encryption key file is read and the above-described encryption key file creation is performed. Then, the corresponding value is displayed on the encryption key display unit 513 and the initialization vector display unit 514.

  In the example of FIG. 21, the decrypted original encryption key and the initialization vector are uniformly represented by the letter "X" in order to prevent the leakage of the encryption key and the like. The checksum is calculated based on the decrypted original encryption key and the initialization vector, and displayed on the checksum display unit 515. The value displayed on the checksum display unit 515 is compared with the checksum value at the time of encryption stored in the encryption key file, and the comparison result is displayed in a predetermined area of the encryption key reading screen 511. It may be. The creation date and time display section 516 displays the creation date and time included in the encryption key file.

  The validity of the encryption key file can be confirmed by such a checksum value and the creation date and time. However, the encryption key display unit 513 displays part or all of the decrypted encryption key as it is. It can also be displayed so that it can be checked whether it matches the original encryption key.

<GAL of the medal selector initialization tool>
Next, a GUI of a medal selector initialization tool (program) for initializing the medal selector 201 will be described with reference to FIG.

  The medal selector initialization tool is executed in the computer 400 as described above, and the screen of the tool is displayed on the display 409 of the computer 400, and inputs and instructions are performed using the keyboard 411, the mouse 412, and the like.

  FIG. 22A shows an initialization instruction screen 521 of the medal selector initialization tool. The initialization instruction screen 521 shows an encryption key IV checksum display section 522, an external I / O communication state display section 523, an initialization button 524, and a status display section 525. FIG. 22A shows an initialization instruction screen 521 before the initialization processing of the medal selector 201 is performed.

  In this case, the encryption key file (XML file) stored in the folder of the external storage device 413 in which the medal selector initialization tool is stored is read, and the checksum included in the XML file is used as the encryption key IV. It is displayed on the checksum display section 522. Here, after decrypting the encryption key and the initialization vector included in the encryption key file, a checksum may be calculated and displayed on the encryption key IV checksum display unit 522. Further, the creation date and time included in the encryption key file may be displayed.

  Further, the computer 400 is not connected to the operation machine 500, and the external I / O communication status display section 523 displays "No connection". When connected to the operation machine 500, the external I / O communication status display section 523 displays, for example, "COM1 connection".

  Further, the status display unit 525 displays “uninitialized” when the initialization has not been performed yet, displays “initialization OK” when the initialization is completed, and displays “error initialization” when an error occurs in the initialization. "Initialization NG" is displayed.

  Here, when the user of the medal selector initialization tool presses the initialization button 524 with the mouse 412 (arrow 526), the medal selector initialization tool holds the medal selector initialization tool internally (or stores it in a predetermined storage unit). The designated encryption key file is decrypted with the encryption key for creating the encryption key file (to be stored), and the decrypted encryption key and the initialization vector are transmitted to the medal selector 201.

  Thereafter, the medal selector initialization tool analyzes that the decrypted encryption key and the initialization vector have been normally received by the medal selector 201 by decrypting predetermined encrypted data received from the medal selector 201. When normal reception by the medal selector 201 is confirmed, "initialization OK" is displayed on the status display section 525 as shown on an initialization instruction screen 521 in FIG. 22B.

  When transmitting the decrypted encryption key and the initialization vector to the medal selector 201, the medal selector initialization tool encrypts the decrypted key and the initialization vector using the encryption key shared with the medal selector 201 and then transmits the encrypted key. You may make it.

  Since such initialization processing may take time, the progress of initialization may be displayed on a progressive bar (status bar).

  By using such a medal selector encryption key creation tool and a medal selector initialization tool, an encryption key can be easily created, and an encryption key can be created and held in a highly secure state ( For example, the key manager can hold the encryption key of each medal selector as an encrypted encryption key file.) This also makes it possible to increase the efficiency of work when a peripheral device such as the medal selector 201 is incorporated into a gaming machine.

  Further, in the gaming machine, the communication data between the main control circuit 91 and the sub-control circuit 101 is not only encrypted but also provided to the medal selector 201 by a medal selector encryption key creation tool and a medal selector initialization tool. Since the communication data between the medal selector 201 and the sub-control circuit 101 is encrypted using the encrypted encryption key), the security of data transmitted and received between the medal selector 201 and the sub-control circuit 101 is increased. Can be maintained at the level.

<Commands transmitted / received between medal selector and sub-control circuit / external computer>
Next, commands transmitted and received between the medal selector 201 and the sub-control circuit 101 and commands transmitted and received between the medal selector 201 and an external computer (computer 400) will be described with reference to FIG. FIG. 23 is a list of commands transmitted and received between the medal selector 201 and the sub-control circuit 101 and between the medal selector 201 and the computer 400.

  Note that all commands transmitted from the sub-control circuit 101 and the computer 400 to the medal selector 201 are encrypted with an encryption key shared by the sub-control circuit 101 or the computer 400 and the medal selector 201.

[Command sent by the medal selector]
First, a command transmitted by the medal selector 201 will be described. As shown in FIG. 23, the commands include a start completion command, a determination completion command, a medal selector error command, a medal selector non-operation command, an ACK command, and a NAK command. Each command is configured to include a 2-byte transmission counter (CNT) and parameters including DAT0 to DAT6. In the present embodiment, DAT0 to DAT6 are each 1-byte (bit 0 to bit 7) data. The data length of each command is set to 9 bytes including the transmission counter, but this data length can be set as appropriate.

  The activation count of the medal selector 201 is set in the initial value of the transmission counter (CNT) in the command transmitted by the medal selector 201. The value of the transmission counter is incremented by one each time the medal selector 201 transmits a command.

  Note that a start completion command, a determination completion command, a medal selector error command, a medal selector non-operation command, an ACK command, and a NAK command are transmitted from the medal selector 201 to the sub control circuit 101. In the present invention, these commands are encrypted by the medal selector 201 using the encryption key received from the computer 400 and transmitted to the sub control circuit 101.

  On the other hand, a start completion command, a medal selector non-operation command, an ACK command, and a NAK command are basically transmitted from the medal selector 201 to the computer 400. In the medal selector 201, an initial encryption key for initial setting and an initial initialization vector are stored in the flash memory 244 when the medal selector 201 is manufactured.

[Start complete command]
The activation completion command is transmitted after the power is turned on to the medal selector 201 and the activation processing is completed. The value of bit 0 of DAT0 of the activation completion command indicates whether the switch response initialization processing has been performed. “0” indicates “no initialization”, and “1” indicates “initialization”. Here, when the switch response initialization process is performed during energization, the control LSI 234 of the medal selector 201 sets “1” to the value of the startup initialization flag storage area of the flash memory 244. When the power is turned on and the start completion command is transmitted, the control LSI 234 refers to the start-up initialization flag storage area of the flash memory 244, and according to the stored value, sets the start completion command DAT0. Set the value of bit 0. If the value of bit 0 of DAT0 of the start-up completion command is “1”, that is, if the value of the start-up initialization flag storage area at start-up is set to “1”, the medal selector 201 When receiving the ACK command for the startup completion command from the computer 400, the control LSI 234 sets “0” to the value of the startup initialization flag storage area.

  The value of bit 1 of DAT0 of the activation completion command indicates whether color determination is valid or invalid at the time of command transmission. The value “0” indicates “color judgment invalid”, and the value “1” indicates “color judgment valid”. The case where “color judgment is valid” is a case where a color template has been created at the time of command transmission and the color switch at the time of startup is in an ON state. In other cases, “color judgment is invalid”. The value of bit 2 of DAT0 of the activation completion command indicates whether the engraving determination is valid or invalid at the time of command transmission. A value “0” indicates “marking judgment invalid”, and a value “1” indicates “marking judgment valid”. The case where “engraving judgment is valid” is a case where the engraving template has been created at the time of command transmission and the engraving switch at the time of startup is in the ON state. In other cases, "marking judgment is invalid".

  DAT1 of the startup completion command indicates the ON / OFF state of various switches at the time of command transmission. The value of bit 0 indicates the ON / OFF state of the initialization switch, the value of bit 1 indicates the ON / OFF state of the color switch, and the value of bit 2 indicates the ON / OFF state of the engraving switch. In any of the bits, “0” indicates the “OFF state” and “1” indicates the “ON state”.

[Judgment completion command]
The determination completion command includes a transmission counter (CNT) and parameters indicating a circular detection determination result, a color determination determination result, and a marking determination determination result. The value of DAT0 of the determination completion command indicates the determination result of circular detection, the value of DAT1 indicates the determination result of color determination, and the value of DAT2 indicates the determination result of engraving determination. In any of the bits, “0” indicates “NG” (ie, “judgment NG”), and “1” indicates “OK” (ie, “judgment OK”).

[Medal selector error command]
The medal selector error command is transmitted when the medal selector 201 detects various errors. This command includes a transmission counter (CNT) and a parameter indicating the type of error occurring at the time of command transmission. The value of DAT0 of the medal selector error command is set to 0-6. “0” indicates “no error”, “1” indicates “foreign matter detection error”, and “2” indicates “cover open error”. “3” indicates “cleaning error”, “4” indicates “color template generation error”, “5” indicates “engraved template generation error”, and “6” indicates “CMOS hard error”. Is shown. When detecting various errors, the control LSI 234 of the medal selector 201 stores the contents (1 to 6) of the error in an error storage area (initial value “0”) provided in the SRAM 243. The content of the error stored in the SRAM 243 is deleted when the medal selector 201 receives an error release command described later from the sub-control circuit 101 (the initial value “0” is stored).

[Medal selector no-operation command]
The medal selector no-operation command is periodically transmitted from the medal selector 201 to the sub-control circuit 101 or the computer 400. The medal selector no-operation command includes a transmission counter (CNT).

  The value of bit 0 of DAT0 of the medal selector no-operation command indicates whether or not the switch response initialization processing has been performed. “0” indicates “no initialization”, and “1” indicates “initialization”. Here, when the switch response initialization processing is performed during energization, the control LSI 234 of the medal selector 201 sets the value of the no-operation initialization flag storage area of the SRAM 243 to “1”. When transmitting the medal selector no-operation command, the control LSI 234 refers to the no-operation initialization flag storage area of the SRAM 243, and according to the stored value, sets the bit 0 of the DAT0 of the medal selector no-operation command. Set the value of. If the value of bit 0 of DAT0 of the medal selector no-operation command is “1”, that is, if the value of the no-operation initialization flag storage area is set to “1”, the medal selector 201 When receiving the ACK command for the medal selector no-operation command from the computer 400, the control LSI 234 sets “0” to the value of the no-operation initialization flag storage area.

  The other medal selector non-operation commands DAT0 and DAT1 are the same as the start complete commands DAT0 and DAT1, and therefore description thereof is omitted here. The content (any value from 0 to 6) of the error storage area of the SRAM 243 is set in the DAT3 of the medal selector non-operation command. The contents are the same as the medal selector error command DAT0.

  The values of DAT3 and DAT4 of the medal selector no-operation command indicate the number of times the medal selector 201 has been activated. This activation count is stored in the flash memory 244, and every time the medal selector 201 is activated, 1 is added to the activation count. More specifically, the medal selector 201 has a control power management unit (not shown). The control power management unit starts supplying power (turning on the power) to the medal selector 201 and sets a predetermined voltage value. , A reset signal is output to the control LSI 234. The control LSI 234 adds 1 to the number of startups based on the input of the reset signal. The medal selector 201 (the control LSI 234 thereof) sets the values of DAT3 and DAT4 by referring to the number of times of activation of the flash memory 244 when transmitting the medal selector non-operation command. Note that the number of times of activation is set to an initial value “0” in a switch response initialization process performed by the control LSI 234 by operating the above-described initialization switch 206d.

[ACK command, NAK command]
The ACK command is transmitted when the medal selector 201 has successfully received the command transmitted from the sub control circuit 101 or the computer 400. The NAK command is transmitted when the medal selector 201 cannot normally receive a command transmitted from the sub control circuit 101 or the computer 400. The ACK command and the NAK command include a transmission counter (CNT). The values of DAT0 and DAT1 of the ACK command and NAK command indicate the values of the transmission counter included in the commands transmitted from the sub-control circuit 101 and the computer 400.

[Command sent by sub-control circuit / computer 400]
Next, commands transmitted from the sub-control circuit 101 and the computer 400 to the medal selector 201 will be described. As shown in FIG. 23, the commands include an initialization command, an encryption key 1 to an encryption key 3 command, an IV1 to IV3 command, an error release command, an input state command, an ACK command, and a NAK command. Each command is configured to include a 2-byte transmission counter (CNT) and parameters including DAT0 to DAT6. In the present embodiment, DAT0 to DAT6 are 1-byte (bit 0 to bit 7) data, respectively. The data length of the data part of each command is set to 9 bytes including the transmission counter, but this data length can be set as appropriate.

  Note that the sub control circuit 101 stores an initial encryption key for initialization and an initialization vector in the ROM cartridge substrate 86 when the sub control circuit 101 is manufactured, and stores the initial encryption key in the external storage device 413 of the computer 400. Are stored.

  The initial value of the transmission counter (CNT) in the command transmitted by the sub-control circuit 101 is set to a random number acquired when the command is transmitted for the first time after the activation of the sub-control circuit 101. In order to generate the random number, a dedicated random number generation process (soft random number) for generating the random number, or a device may be provided, or a random number generation for generating a random number used in determining an effect mode may be provided. Processing or a device may be used.

  The initial value of the transmission counter (CNT) in the command transmitted by the computer 400 is set to a random number acquired when the command is transmitted for the first time after the medal selector initialization tool is activated in the computer 400. This random number is generated by, for example, an internal program by the medal selector initialization tool.

  Note that the sub control circuit 101 transmits an error release command, an insertion state command, an ACK command, and a NAK command to the medal selector 201. In the present invention, these commands are encrypted with the encryption key held by the sub control circuit 101 and transmitted to the medal selector 201. The encryption key held by the sub control circuit 101 is the same as the encryption key transmitted from the computer 400 to the medal selector 201.

  On the other hand, an initialization command, an encryption key 1 to an encryption key 3 command, an IV 1 to IV 3 command, an ACK command, and a NAK command are basically transmitted from the computer 400 to the medal selector 201.

[Initialization command]
The initialization command is a command for notifying that the computer 400 performs an initialization process on the medal selector 201 and thereafter starts a process of transmitting an encryption key and an initialization vector. The initialization process is a process of clearing predetermined data stored in the flash memory 244 of the medal selector 201, for example.

[Encryption Key 1 to Encryption Key 3 Command]
The encryption key 1 to encryption key 3 commands are transmitted in order following the above-mentioned initialization command, and transmit the encryption keys created by the computer 400 to the medal selector 201, respectively. The first seven bytes of data of the encryption key are stored in DAT0 to DAT6 of the encryption key 1 command. DAT0 to DAT6 of the encryption key 2 command store seven bytes of data from the eighth byte of the encryption key. Two bytes of data from the 15th byte of the encryption key are stored in DAT0 to DAT1 of the encryption key 3 command.

[IV1-IV3 commands]
The IV1 to IV3 commands are sequentially transmitted following the above-described encryption key 1 to encryption key 3 commands, and transmit the initialization vector (IV) created by the computer 400 to the medal selector 201, respectively. The first seven bytes of data of the initialization vector are stored in DAT0 to DAT6 of the IV1 command. In the DAT0 to DAT6 of the IV2 command, data of 7 bytes from the 8th byte of the initialization vector is stored. Two bytes of data from the 15th byte of the initialization vector are stored in DAT0 to DAT1 of the IV3 command.

[Error clear command]
The error canceling command is transmitted when a condition for canceling an error that has occurred in the medal selector 201 is satisfied in a medal selector command transmitting process (see FIG. 33) described later. However, the satisfaction of the error cancellation condition does not mean whether the error occurred in the medal selector 201 has actually been canceled, but whether the condition for transmitting the error cancellation command has been met.

[Input status command]
The insertion state command is transmitted in a predetermined cycle or in a medal selector command transmission process described later (see FIG. 33). The value of DAT0 of the insertion state command indicates whether or not medals can be accepted. “1” indicates “acceptable”, and “0” indicates “acceptable”.

[ACK command, NAK command]
The ACK command is transmitted when the sub-control circuit 101 or the computer 400 has successfully received the command transmitted from the medal selector 201. The NAK command is transmitted when the sub control circuit 101 or the computer 400 cannot normally receive the command transmitted from the medal selector 201. The ACK command and the NAK command include a transmission counter. The values of DAT0 and DAT1 of the ACK command and the NAK command indicate the values of the transmission counter included in the command transmitted from the medal selector 201.

<Command transmission / reception sequence between medal selector and external computer>
Next, an example of a command transmission / reception sequence between the medal selector 201 and the external computer (computer 400) will be described with reference to FIG. FIG. 24 is a diagram illustrating an example of a command transmission / reception sequence between the medal selector 201 and the computer 400.

  When the computer 400 and the medal selector 201 are connected and the medal selector 201 is activated, the medal selector 201 transmits a startup completion command to the computer 400. At this time, when the number of activations stored in the flash memory 244 is “10”, the value of the transmission counter (CNT) included in the activation completion command is “10”.

  Subsequently, the computer 400 that has normally received the activation completion command transmits an ACK command to the medal selector 201. The value of the transmission counter included in this ACK command is the value of the random number acquired at the time of transmission, for example, “256”. Further, the values of DAT0 and DAT1 of the ACK command are “10” which is the value of the transmission counter included in the received activation completion command.

  Subsequently, in the example illustrated in FIG. 24, the medal selector 201 transmits a medal selector non-operation command to the computer 400. The value of the transmission counter included in the medal selector no-operation command is “11” which is obtained by adding 1 to the initial value “10”.

  Subsequently, the computer 400 that has normally received the medal selector non-operation command transmits an ACK command to the medal selector 201. The value of the transmission counter included in this ACK command is “257” obtained by adding 1 to the initial value “256”. The values of DAT0 and DAT1 of the ACK command are “11” which is the value of the transmission counter included in the received medal selector non-operation command.

  Here, when initialization of the medal selector is instructed in the medal selector initialization tool executed by the computer 400, the computer 400 transmits an initialization command to the medal selector 201 in response to this operation. The value of the transmission counter included in this initialization command is “258” obtained by adding 1 to “257”.

  Subsequently, the medal selector 201 that has normally received the initialization command transmits an ACK command to the computer 400. The value of the transmission counter included in this ACK command is “12” which is obtained by adding 1 to the value of the latest transmission counter. The values of DAT0 and DAT1 of this ACK command are “258” which is the value of the transmission counter included in the received initialization command.

  Next, the medal selector initialization tool executed on the computer 400 transmits the encryption key 1 command to the medal selector 201. The value of the transmission counter included in this encryption key 1 command is “259”.

  Subsequently, the medal selector 201 that has normally received the encryption key 1 command transmits an ACK command to the computer 400. The value of the transmission counter included in this ACK command is “13” obtained by adding 1 to the value of the latest transmission counter. The values of DAT0 and DAT1 of the ACK command are “259” which is the value of the transmission counter included in the received encryption key 1 command.

  Next, the medal selector initialization tool executed on the computer 400 transmits the encryption key 2 command to the medal selector 201. The value of the transmission counter included in this encryption key 2 command is “260”.

  Subsequently, the medal selector 201 that has normally received the encryption key 2 command transmits an ACK command to the computer 400. The value of the transmission counter included in this ACK command is “14” obtained by adding 1 to the value of the latest transmission counter. The values of DAT0 and DAT1 of the ACK command are “260” which is the value of the transmission counter included in the received encryption key 2 command.

  Next, the medal selector initialization tool executed on the computer 400 transmits the encryption key 3 command to the medal selector 201. The value of the transmission counter included in this encryption key 3 command is “261”.

  Subsequently, the medal selector 201 that has normally received the encryption key 3 command transmits an ACK command to the computer 400. The value of the transmission counter included in this ACK command is “15” obtained by adding 1 to the value of the latest transmission counter. The values of DAT0 and DAT1 of the ACK command are “261”, which is the value of the transmission counter included in the received encryption key 3 command.

  Next, the medal selector initialization tool executed on the computer 400 transmits an IV1 command to the medal selector 201. The value of the transmission counter included in this IV1 command is “262”.

  Subsequently, the medal selector 201 that has normally received the IV1 command transmits an ACK command to the computer 400. The value of the transmission counter included in this ACK command is “16” obtained by adding 1 to the value of the latest transmission counter. The values of DAT0 and DAT1 of the ACK command are “262” which is the value of the transmission counter included in the received IV1 command.

  Next, the medal selector initialization tool executed on the computer 400 transmits an IV2 command to the medal selector 201. The value of the transmission counter included in this IV2 command is “263”.

  Subsequently, the medal selector 201 that has normally received the IV2 command transmits an ACK command to the computer 400. The value of the transmission counter included in this ACK command is “17” obtained by adding 1 to the value of the latest transmission counter. The values of DAT0 and DAT1 of the ACK command are “263” which is the value of the transmission counter included in the received IV2 command.

  Next, the medal selector initialization tool executed on the computer 400 transmits an IV3 command to the medal selector 201. The value of the transmission counter included in this IV3 command is “264”.

  Subsequently, the medal selector 201 that has normally received the IV3 command transmits an ACK command to the computer 400. The value of the transmission counter included in this ACK command is “18” obtained by adding 1 to the value of the latest transmission counter. The values of DAT0 and DAT1 of the ACK command are “264” which is the value of the transmission counter included in the received IV3 command.

  Here, the computer 400 further updates the GUI in the medal selector initialization tool and displays “initialization OK” on the status display unit 525 (see FIG. 22B).

  Note that “Initialization OK” is displayed only when the medal selector 201 transmits an ACK command when the IV3 command is transmitted after the transmission of the initialization command, and all of the ACK commands are normally decoded. If the initialization fails or the NAK command is transmitted, “initialization NG” is displayed on the status display unit 525.

  All commands transmitted by the medal selector 201 and the computer 400 are all encrypted with the encryption key and the initialization vector before being set by the encryption keys 1 to 3 and the IV1 to IV3 commands. Therefore, the medal selector 201 and the computer 400 assume that the encryption key and the initialization vector are stored as the initial values. A NAK command is transmitted to the computer 400.

  In addition, the medal selector 201 transmits a command to the computer 400 at a cycle of 500 msec. For example, in the example illustrated in FIG. 24, the medal selector non-operation command is transmitted to the computer 400 500 msec after the activation completion command is transmitted to the computer 400. The cycle at which the command is transmitted from the medal selector 201 to the computer 400 can be set as appropriate.

<Process of the medal selector encryption key creation tool>
Next, an example of the encryption processing of the medal selector encryption key creation tool executed in the external computer (computer 400) will be schematically described with reference to the flowchart in FIG.

  First, in step S1, for example, it is determined whether or not the user has input an encryption key to the encryption key input unit 503 of the encryption key creation screen 501 shown in FIG. 20A. If the encryption key has not been input (NO in step S1), the process returns to step S1 and repeats this process. The input encryption key may be displayed as it is on the encryption key input unit 503, or may be converted to another character when input. You may do so.

  If an encryption key is input (YES in step S1), an initialization vector is generated using a random number generation program of a medal selector encryption key generation tool in step S2, for example, an encryption key generation screen shown in FIG. 20B. The value is displayed on an initialization vector display unit 504 of the reference numeral 501. Next, in step S3, a checksum is calculated based on the input encryption key and the generated initialization vector, and the calculated checksum is displayed on the checksum display unit 505 of the encryption key creation screen 501 shown in FIG. 20B. Displays the checksum value.

  Next, in step S4, it is determined whether or not a creation button for instructing creation of an encryption key file (the creation instruction button 507 of the encryption key creation screen 501 shown in FIG. 20B) has been pressed. If the create button has not been pressed (NO in step S4), the process returns to step S4 and repeats this process.

  If the creation button has been pressed (YES in step S4), in step S5, the encryption key and the initialization vector are encrypted to create an encryption key file. This encryption key file is, for example, a file in an XML format, and can include an encrypted key and an initialization vector, as well as the above-described checksum value and the creation date and time.

  Next, in step S6, the created encryption key file is stored in a predetermined storage medium (for example, an external storage device 413 including a hard disk or a semiconductor memory, or an external storage medium 430 such as a portable flash memory). Then, in step S7, a message indicating that the creation of the encryption key file has been completed is displayed in a predetermined area of the encryption key creation screen 501 shown in FIG. 20B.

<Process of the medal selector initialization tool>
Next, an example of the initialization processing of the medal selector initialization tool executed in the external computer (computer 400) will be schematically described with reference to the flowchart in FIG.

  First, in step S11, an initialization file (not shown) is read from the external storage device 413. This initialization file is a file in which an encryption key and an initialization vector for communicating with the medal selector 201 when the medal selector 201 is initialized for the first time are stored. The initialization file is overwritten and saved with the encryption key and the initialization vector decrypted in step S29 (the timing of saving is, for example, the timing of step S25 described later).

  Next, in step S12, it is determined whether or not a command has been received from the medal selector 201. If a command has been received (YES in step S12), the received command is decoded in step S13.

  After decrypting the received command in step S13, it is determined in step S14 whether the received command has been successfully decrypted. If the received command has been successfully decoded (YES in step S14), it is determined in step S15 whether the received command is a “startup completed command”. If the received command is a “start completion command” (YES in step S15), in step S16, the start flag is turned ON. In this case, for example, the GUI of the medal selector initialization tool shown in FIG. After the process in step S16, the process returns to the determination in step S12.

  If the received command is not the “start completion command” (NO in step S15), it is determined in step S17 whether the received command is “medal selector non-operation”. If the received command is “medal selector non-operation” (YES in step S17), a predetermined medal selector non-operation command reception process is performed in step S18. Here, the medal selector non-operation command reception processing may be skipped. After step S18, the process returns to step S12.

  If the received command is not “medal selector no operation” (NO in step S17), it is determined in step S19 whether the received command is “NAK”. If the received command is “NAK” (YES in step S19), the command is retransmitted to the medal selector 201 in step S20. After step S20, the process returns to step S12.

  If the received command is not “NAK” (NO in step S19), it is determined in step S21 whether the received command is “ACK”. If the received command is not “ACK” (NO in step S21), the process returns to the determination in step S12. If the received command is “ACK” (YES in step S21), it is determined in step S22 whether or not there is a transmission command.

  If there is a transmission command (YES in step S22), in step S23, a command such as an encryption key such as an initialization command, an encryption key 1 to an encryption key 3 command, an IV1 command, and an IV2 command. ) Is transmitted to the medal selector 201. In this case, the decoded data corresponding to the command is stored in DAT0 to DAT6. Then, after step S23, the process returns to step S12.

  If there is no transmission command (NO in step S22), it is determined in step S24 whether all commands such as an encryption key have been transmitted. If all the commands such as the encryption key have been transmitted (YES in step S24), in step S25, for example, as shown in FIG. 22B, the GUI is updated by the medal selector initialization tool, and the status display unit 525 displays Is displayed (step S25). After step S25, the process returns to the determination in step S12.

  If all commands such as an encryption key have not been transmitted (NO in step S24), or if the received command has not been successfully decrypted (NO in step S14), the GUI is reset by the medal selector initialization tool. Update is performed, and “initialization NG” is displayed on the status display section 525 (step S26). Thereafter, the process returns to the determination in step S12.

  If a command has not been received from the medal selector 201 (NO in step S12), the process proceeds to step S27, where it is determined whether or not a file reading instruction regarding an encryption key file has been issued in the medal selector initialization tool. The file reading instruction is, for example, an instruction to display a file reading instruction screen on an initialization menu screen (not shown) before the initialization instruction screen 521 of the medal selector initialization tool shown in FIG. 22A is displayed, This is performed by specifying an encryption key file to be used for initialization on the displayed file reading instruction screen.

  If a file reading instruction regarding the encryption key file is issued (YES in step S27), the specified encryption key file is read in step S28, and then the read encryption key file is decrypted in step S29. . After step S29, the process returns to the determination in step S12.

  If the file reading instruction regarding the encryption key file has not been issued (NO in step S27), in step S30, it is determined whether or not an initialization instruction has been issued by the medal selector initialization tool, that is, an initialization button 524 (see FIG. 22A). ) Is determined. If the initialization instruction has been given (YES in step S30), it is determined in step S31 whether the activation flag is ON.

  If it is determined that the activation flag is ON (YES in step S31), that is, if the activation completion command has been received from the medal selector 201 and the connection with the medal selector 201 has been normally performed, in step S32 Then, a command such as an encryption key is generated (that is, the encryption key file (encryption key and initialization vector) decrypted in step S29 is allocated to DAT0 to DAT6 of each command). Next, in step S33, an initialization command is transmitted to the medal selector 201. When the initialization instruction has not been issued (NO in step S30), or after step S33, the process returns to the determination in step S12.

  If it is not determined that the activation flag is ON (NO in step S31), it is determined that the connection with the medal selector 201 has not been normally established, and an error message to that effect is displayed by the medal selector initialization tool ( Step S34). After step S34, the process returns to step S12.

  In the example shown in FIG. 26, after the encryption key file created by the medal selector encryption key creation tool is temporarily decrypted to obtain the original encryption key and the initialization vector, these encryption keys are used. And the initialization vector are divided and transmitted to the medal selector 201 by a plurality of commands. In this case, the data assigned to DAT0 to DAT6 of each command is individually encrypted with the above-described different encryption key. It is configured to be.

  It is also assumed that the data of the command received from the medal selector 201 has been encrypted with the above-mentioned another encryption key, but in the flowchart of FIG. The decoding process has been omitted.

<Various processes performed by the medal selector>
Next, an example of a process executed in the medal selector 201 will be schematically described with reference to a flowchart of FIG. When the medal selector 201 is connected to the sub control circuit 101, the medal selector 201 transmits a determination completion command, a medal selector error command, and the like to the sub control circuit 101, and performs a medal determination process. The following description focuses on processing performed with the computer 400 when connected to an external computer (computer 400), and description of other processing is omitted as appropriate.

  First, the power of the medal selector 201 is turned on by connection with the computer 400, and when the startup process ends, in step S41, a startup completion command is transmitted to the computer 400. The activation completion command is as described above.

  Next, the medal selector 201 determines whether or not a predetermined timing has arrived (step S42), and when it has been determined (YES in step S42), in step S43, the medal selector non-operation command is transmitted to the computer 400. Send to Thereby, the medal selector no-operation command is transmitted from the medal selector 201 to the computer 400 periodically (for example, at a cycle of 500 msec). The medal selector no-operation command is as described above. After step S43, the process returns to step S42, and the determination of the predetermined timing is repeated.

  If the predetermined timing has not come (NO in step S42), it is determined in step S44 whether a command has been received from the computer 400 (step S44). If the command has not been received (NO in step S44), the process returns to step S42 and the determination of the predetermined timing is repeated.

  If a command has been received (YES in step S44), the received command is decoded in step S45. Thereafter, in step S46, it is determined whether or not the received command has been successfully decoded. If the received command has been successfully decrypted (YES in step S46), it is determined in step S47 whether the received command is related to transmission of an encryption key. The command related to the transmission of the encryption key is, for example, an initialization command, an encryption key 1 to an encryption key 3 command, and an IV 1 to IV 3 command.

  If the received command is a command related to transmission of the encryption key (YES in step S47), an ACK is transmitted (to the computer 400) for the received command in step S48. After that, the decrypted encryption key and the initialization vector are stored in the SRAM 243 (step S49). When receiving the initialization command, the medal selector 201 performs a predetermined initialization process such as clearing predetermined data stored in the flash memory 244.

  Next, in step S50, it is determined whether or not this is the last command related to the transmission of the encryption key (that is, the IV3 command in this example). If it is the last command (YES in step S50), the encryption key and the initialization vector stored in the SRAM 243 are stored in the flash memory 244 in step S51. Thereafter, the process returns to step S42, and the determination of the predetermined timing is repeated. If it is not the last command (NO in step S50), the process returns to step S42 and the determination of the predetermined timing is repeated.

  If the received command is not a command related to the transmission of the encryption key (NO in step S47), it is determined in step S52 whether the received command is an ACK command or a NAK command. If the received command is an ACK command or a NAK command (YES in step S52), in step S53, a predetermined ACK / NAK command reception process is performed. When the received command is not the ACK command or the NAK command (NO in step S52), or after step S53, the process returns to step S42 to repeat the determination of the predetermined timing.

  If the received command cannot be decoded normally (NO in step S46), an abnormal process is performed in step S54. This abnormality processing corresponds to the occurrence of an abnormality when the medal selector 201 is not connected to the sub-control circuit 101. Further, although the connection with the computer 400 is established, the abnormality occurs in the connection. Therefore, for example, the occurrence of the abnormality can be notified by the medal selector 201, for example, by turning on the notification LED 206c or the like.

  At this time, the medal selector 201 can perform a reboot (restart), and control can be performed so as to start over from the first step S41. Specifically, updating (refreshing) of a WDT (Watch Dog Timer: not shown) built in the control LSI 234 is stopped, and a standby process is performed until the WDT outputs a reset signal to the host controller 241 (see FIG. 14). . When the reboot is not performed in the abnormal process, the process returns to step S42, and control can be performed so that the determination of the predetermined timing is repeated.

<Command transmission / reception sequence between medal selector and sub-control circuit>
Next, an example of a command transmission / reception sequence between the medal selector and the sub control circuit will be described with reference to FIG. FIG. 28 is a diagram for explaining an example of a command transmission / reception sequence between the medal selector and the sub control circuit.

  When the power is turned on to the pachislot 1 and the medal selector 201 and the sub-control circuit 101 are activated, the medal selector 201 transmits an activation completion command to the sub-control circuit 101. At this time, when the number of activations stored in the flash memory 244 is “10”, the value of the transmission counter (CNT) included in the activation completion command is “10”.

  Subsequently, the sub-control circuit 101 that has normally received the activation completion command transmits an ACK command to the medal selector 201. The value of the transmission counter included in this ACK command is the value of the random number acquired at the time of transmission, for example, “256”. Further, the values of DAT0 and DAT1 of the ACK command are “10” which is the value of the transmission counter included in the received activation completion command.

  Subsequently, in the example illustrated in FIG. 28, the medal selector 201 transmits a medal selector non-operation command to the sub control circuit 101. The value of the transmission counter included in the medal selector no-operation command is “11” which is obtained by adding 1 to the initial value “10”.

  Subsequently, the sub-control circuit 101 that has normally received the medal selector non-operation command transmits an ACK command to the medal selector 201. The value of the transmission counter included in this ACK command is “257” obtained by adding 1 to the initial value “256”. The values of DAT0 and DAT1 of the ACK command are “11” which is the value of the transmission counter included in the received medal selector non-operation command.

  Subsequently, in the example illustrated in FIG. 28, the sub-control circuit 101 transmits an insertion state command to the medal selector 201. The value of the transmission counter included in the input state command is “258” obtained by adding 1 to “257”. Here, when the medal selector reboots (restarts) for some reason and transmits an ACK command corresponding to the insertion state command after the restart, the transmission counter included in this ACK command becomes the initial value again. In this case, since the number of times of activation is “11”, the transmission counter included in the ACK command is “11”.

  In the present embodiment, when the sub control circuit 101 receives the ACK command from the medal selector 201, the value of the transmission counter included in the received ACK command is included in the command previously received from the medal selector 201. It is determined whether the value of the transmission counter is equal to a value obtained by adding “1”. If it is determined that they are not equal to each other, the error information history area provided in the sub RAM 103 stores "CMOS CNT" (hereinafter sometimes referred to as "ACK count error") as the error content and the current date as the date and time of occurrence. And the time.

  In the example shown in FIG. 28, the value of the transmission counter included in the received ACK command is “11”. The value obtained by adding “1” to the transmission counter value “11” included in the medal selector non-operation command, which is the command received from the medal selector 201 last time, is “12”. Therefore, the sub CPU 102 determines that these values are not equal. Therefore, the sub CPU 102 stores “CMOS CNT” (ACK count error) as the error content and the current date and time as the occurrence date and time in the error information history area provided in the sub RAM 103.

  Further, the medal selector 201 transmits a command to the sub-control circuit 101 at a cycle of 500 msec. For example, in the example shown in FIG. 28, a medal selector non-operation command is transmitted to the sub-control circuit 101 500 msec after the start completion command is transmitted to the sub-control circuit 101. Note that the cycle at which the command is transmitted from the medal selector 201 to the sub-control circuit 101 can be set as appropriate.

<Various processes performed by the sub control circuit>
Next, various processes performed by (sub CPU 102 of) sub-control circuit 101 will be schematically described with reference to FIGS. 29 to 33.

[Power on process]
The power-on process will be described with reference to FIG. FIG. 29 is a flowchart illustrating an example of the power-on process. The sub CPU 102 performs power-on processing when the power of the pachislot 1 is turned on. In the power-on process, first, the sub CPU 102 performs a power-on initialization process (step S101). Specifically, the sub CPU 102 executes initialization of each driver and activation of a kernel (kernel or Operating System). (In the present embodiment, the process of transmitting the encryption key to the medal selector 201 is referred to as “initialization process”, and the initialization process performed in response to the operation of the initialization switch 206d is “switch response”. Initialization processing at the time of power-on of the sub-control circuit 101 is referred to as "power-on initialization processing" to be distinguished therefrom.)

  Next, the sub CPU 102 adds 1 to (the value of) the sub power-on counter provided in the sub RAM 103 (step S102). Specifically, the sub-control circuit 101 includes a sub-control power management unit (not shown). The sub-control power management unit starts supplying power (turning on the power) to the sub-control circuit 101 and sets the sub-control power in advance. When the voltage value exceeds the set voltage value, a reset signal is output to a reset terminal (not shown) of the sub CPU 102. The sub CPU 102 adds 1 to (the value of) the sub power-on counter based on the input of the reset signal. Note that the sub power-on counter is initialized when the medal selector 201 is initialized, and the sub control circuit 101 receives a start completion command from the medal selector 201 from which initialization is set (bit 0 of DAT0 is set to 1). Is cleared (0 is set). Then, the sub CPU 102 ends the power-on process.

[Medal Selector Communication Task]
Next, the medal selector communication task will be described with reference to FIG. FIG. 30 is a flowchart illustrating an example of the medal selector communication task. The sub CPU 102 executes the medal selector communication task after the power-on process.

  In the medal selector communication task, first, the sub CPU 102 performs a waiting process for a period of 10 msec (step S121). Specifically, the sub CPU 102 does not shift the processing to step S122 until 10 msec elapses after the processing shifts to step S121, and shifts the processing to step S122 after elapse of 10 msec. In other words, the processing after step S122 of the medal selector communication task is performed every 10 msec.

  Next, the sub CPU 102 determines whether or not there is received data in the medal selector receiving buffer (step S122). The medal selector reception buffer is provided in the sub RAM 103, and temporarily stores various commands and data transmitted from the medal selector 201 to the sub control circuit 101.

  When it is determined in step S122 that there is no reception data in the medal selector reception buffer (when step S122 is NO), the sub CPU 102 shifts the processing to step S121. On the other hand, if it is determined in step S122 that there is received data in the medal selector reception buffer (YES in step S122), sub CPU 102 performs a medal selector command reception process (step S123). In the medal selector command receiving process, the sub CPU 102 executes various processes according to the command received from the medal selector 201. Further, since the command received from the medal selector 201 is encrypted by the medal selector 201 using the encryption key received from the computer 400, the command is decrypted using the encryption key. Details of the medal selector command receiving process will be described later.

  Next, the sub CPU 102 performs a medal selector command transmission process (step S124). In the medal selector command transmission process, the sub CPU 102 transmits various commands to the medal selector 201. The command transmitted to the medal selector 201 is encrypted with the same key as the encryption key received by the medal selector 201 from the computer 400. Details of the medal selector command transmission processing will be described later. After step S124, sub CPU 102 shifts the processing to step S121.

[Medal selector command reception processing]
The medal selector command receiving process will be described with reference to FIG. FIG. 31 is a flowchart illustrating an example of the medal selector command receiving process. In the medal selector command receiving process, first, the sub CPU 102 determines whether or not the command received from the medal selector 201 is a start completion command (step S131).

  Note that all the commands received from the medal selector 201 are encrypted, and the sub CPU 102 executes the subsequent processing after decrypting all the received commands with the encryption key.

  If it is determined in step S131 that the received command is a startup completion command (step S131 is YES), the sub CPU 102 performs a startup completion command reception process (step S132). The processing at the time of receiving the start-up completion command is, for example, after decrypting the start-up completion command with an encryption key, obtains initialization information and switch information relating to the medal selector 201 from the decryption result, stores them, and initializes them. According to the contents of the information and the switch information, control is performed so that a predetermined error screen is displayed on the liquid crystal display device 11 of the pachislot 1. After that, the sub CPU 102 ends the medal selector command receiving process, and returns the process to the step S124 of the medal selector communication task (see FIG. 30).

  On the other hand, if it is determined in step S131 that the received command is not the activation completion command (if step S131 is NO), the sub CPU 102 determines whether the command received from the medal selector 201 is a determination completion command ( Step S133).

  If it is determined in step S133 that the received command is a determination completion command (YES in step S133), sub CPU 102 performs a determination completion command reception process (step S134). The process at the time of receiving the determination completion command is, for example, after decrypting the determination completion command with an encryption key, registering the determination result obtained from the decryption result in a queue, and when the NG determination is equal to or greater than a threshold value, If the value is equal to or more than the predetermined value, control is performed such that a predetermined error screen is displayed on the liquid crystal display device 11 of the pachislot 1. After that, the sub CPU 102 ends the medal selector command receiving process, and returns the process to the step S124 of the medal selector communication task (see FIG. 30).

  On the other hand, if it is determined in step S133 that the received command is not the determination completion command (if step S133 is NO), the sub CPU 102 determines whether the command received from the medal selector 201 is a medal selector error command. (Step S135).

  If it is determined in step S135 that the received command is a medal selector error command (if step S135 is YES), the sub CPU 102 performs a medal selector error command receiving process (step S136). Details of the medal selector error command receiving process will be described later. After that, the sub CPU 102 ends the medal selector command receiving process, and returns the process to the step S124 of the medal selector communication task (see FIG. 30).

  On the other hand, if it is determined in step S135 that the received command is not a medal selector error command (if step S135 is NO), the sub CPU 102 determines whether the command received from the medal selector 201 is an ACK or a NAK command. (Step S137).

  If it is determined in step S137 that the received command is an ACK or NAK command (YES in step S137), the sub CPU 102 performs an ACK / NAK command reception process (step S138). In the ACK / NAK command receiving process, various processes are performed according to the received ACK / NAK command. Note that examples of various processes include instructing the liquid crystal display device 11 to end display of a C1 error screen (not shown) when an ACK command for an error release command described later is received from the medal selector 201, or May be registered in the error information history. After that, the sub CPU 102 ends the medal selector command receiving process, and returns the process to the step S124 of the medal selector communication task (see FIG. 30).

  On the other hand, if it is determined in step S137 that the received command is not an ACK command or a NAK command (if step S137 is NO), the sub CPU 102 determines whether the command received from the medal selector 201 is a medal selector non-operation command. Is determined (step S139).

  If it is determined in step S139 that the received command is a medal selector non-operation command (YES in step S139), the sub CPU 102 performs a medal selector non-operation command reception process (step S140). The process at the time of receiving the medal selector non-operation command, for example, after the medal selector non-operation command is decrypted with the encryption key, when it is determined that “initialization is performed” based on the value of DAT0 obtained from the decryption result, Control is performed to display an initialization error screen on the liquid crystal display device 11 of the pachislot 1. Also, the number of activations is determined based on the values of DAT3 and DAT4 obtained from the decoding result, and when the number of activations satisfies a predetermined condition, a predetermined error screen is displayed on the liquid crystal display device 11 of the pachislot 1. Control. Further, based on the value of DAT1 obtained from the decryption result, the state of various switches of the medal selector 201 is confirmed, and if there is a change, it is registered in the error information history. Further, the above-described processing at the time of receiving the medal selector error command is performed. As a result, even if a failure occurs and the sub-control circuit 101 cannot receive the error command from the medal selector 201, the sub-control circuit 101 receives the medal selector non-operation command, and The error state where the error has occurred can be appropriately detected and notified. After that, the sub CPU 102 ends the medal selector command receiving process, and returns the process to the step S124 of the medal selector communication task (see FIG. 30).

  On the other hand, if it is determined in step S139 that the received command is not the medal selector non-operation command (NO in step S139), the sub CPU 102 ends the medal selector command receiving process, and proceeds to the medal selector communication task ( The process returns to step S124 of FIG. 30).

[Process when receiving a medal selector error command]
The process at the time of receiving the medal selector error command will be described with reference to FIG. FIG. 32 is a flowchart illustrating an example of a process when a medal selector error command is received.

  In the process when receiving a medal selector error command, first, the sub CPU 102 determines whether or not a C1 error is occurring (step S171). Specifically, the sub CPU 102 checks whether or not a C1 error screen is displayed on the liquid crystal display device 11, determines that an error has occurred if the C1 error screen is being displayed, and determines that an error has occurred. It is determined that no error has occurred.

  In the present embodiment, there are two types of errors related to the medal selector, a C1 error and a C2 error. The C2 error is an error determined to have occurred by (the sub CPU 102 of) the sub control circuit 101. When a C2 error occurs, a C2 error screen is displayed.

  On the other hand, the C1 error is an error determined to have occurred by (the control LSI 234 of) the medal selector 201. In the present embodiment, there are six types of C1 errors: a foreign object detection error, a cover opening error, a cleaning error, a color template generation error, an engraved template generation error, and a hard error.

  If it is determined in step S171 that a C1 error is occurring (if step S171 is determined to be YES), the sub CPU 102 terminates the medal selector error command receiving process, and proceeds to the medal selector communication task (FIG. 30). Return to step S124).

  On the other hand, when it is determined in step S171 that the C1 error is not occurring (when step S171 is NO), the sub CPU 102 decrypts the received medal selector error command with the encryption key and receives the medal selector error command from the decryption result. It is determined whether the error status of the buffer is 0 (step S172). Specifically, the sub CPU 102 refers to DAT0 of the medal selector error command of the reception buffer storing the decoding result or DAT2 of the medal selector non-operation command, and refers to the data indicating the error state stored therein. . Then, it is determined whether or not the value is “0” indicating “no error”.

  If it is determined in step S172 that the value of the data indicating the error state is “0” (if step S172 is YES), the sub CPU 102 ends the medal selector error command receiving process, and sets the process to the medal selector. The process returns to step S124 of the communication task (see FIG. 30).

  On the other hand, if it is determined in step S172 that the value of the data indicating the error state is not “0” (NO in step S172), sub CPU 102 issues a C1 error screen display request (step S173). Specifically, the sub CPU 102 instructs the liquid crystal display device 11 to display a C1 error screen.

  Next, the sub CPU 102 registers a “C1_ *” error in the error information history (step S174). Specifically, the sub CPU 102 stores, in an error information history area provided in the sub RAM 103, an error content (one of “1” to “6”) corresponding to the error state of the command stored in the reception buffer. Register the current date and time as the occurrence date and time. For example, when the error state of the command stored in the reception buffer is “5” indicating “engraved template generation error”, “C1_5” is registered as the error content. Then, the sub CPU 102 ends the process at the time of receiving the medal selector error command, and returns the process to the step S124 of the medal selector communication task (see FIG. 30).

[Medal selector command transmission processing]
Next, the medal selector command transmission processing will be described with reference to FIG. FIG. 33 is a flowchart illustrating an example of a medal selector command transmission process.

  The sub CPU 102 transmits all the commands to the medal selector 201 after encrypting them with the encryption key.

  In the medal selector command transmission processing, the sub CPU 102 first determines whether or not an ACK command or a NAK command has been received (step S221). Specifically, the sub CPU 102 determines whether the command received most recently from the medal selector 201 is an ACK command or a NAK command. If it is determined that an ACK command or a NAK command has been received (YES in step S221), sub CPU 102 shifts the processing to step S223 described below.

  On the other hand, if it is determined in step S221 that the ACK command or the NAK command has not been received (NO in step S221), the sub CPU 102 performs an ACK command / NAK command transmission process (step S222). In this processing, the sub CPU 102 transmits the encrypted ACK command or NAK command to the medal selector 201 after encrypting the ACK command or NAK command with the encryption key. Then, the sub CPU 102 ends the medal selector command transmission processing.

  If it is determined in step S221 that an ACK command or a NAK command has been received (YES in step S221), the sub CPU 102 performs an error release determination process (step S223). In the error release determination process, when the release conditions relating to various errors are satisfied, the sub CPU 102 sets the release condition flag relating to the error for which the release conditions are satisfied to be satisfied (sets the value “1”).

  Next, the sub CPU 102 determines whether the C1 error has occurred and whether the release condition flag is satisfied (step S224). Specifically, the sub CPU 102 determines whether or not a C1 error is occurring based on whether or not a C1 error screen is displayed on the liquid crystal display device 11. The sub CPU 102 determines whether the release condition flag is established based on whether “1” is set in the release condition flag storage area provided in the sub RAM 103. When it is determined that the C1 error is not occurring or the release condition flag is not satisfied (NO in step S224), the sub CPU 102 shifts the processing to step S226 described below.

  On the other hand, when it is determined in step S224 that the release condition flag is satisfied (YES in step S224), sub CPU 102 performs an error release command transmission process (step S225). In this process, the sub CPU 102 transmits an error release command to the medal selector 201. Here, the error release command is transmitted to the medal selector 201 after being encrypted with the encryption key. Then, the sub CPU 102 ends the medal selector command transmission processing. Note that when the sub control circuit 101 receives an ACK command corresponding to the error release command from the medal selector 201 from the medal selector 201, the sub CPU 102 performs the ACK command / NAK command receiving process of step S138 of the above-described medal selector command receiving process (FIG. 31). , Instructs the liquid crystal display device 11 to end displaying the C1 error screen.

  If it is determined in step S224 that the release condition flag is not satisfied (if step S224 is NO), sub CPU 102 determines whether or not the medal acceptance flag indicates that the medal cannot be accepted (step S226). The medal acceptance flag storage area is provided in the sub RAM 103. In the medal reception flag storage area, in the case of the ON state based on the information of the ON / OFF state of the medal solenoid 208 included in the no-operation command received from the main control circuit 91 in steps S229 and S232 to be described later. Is set to "1" (acceptable), and in the OFF state, "0" (acceptable). If it is determined in step S226 that the medal acceptance flag is not set to indicate that medal acceptance is not possible (acceptance is possible) (if step S226 is NO), sub CPU 102 shifts the processing to step S230 described later.

  When it is determined in step S226 that the medal reception flag indicates that the medal cannot be received (YES in step S226), sub CPU 102 determines whether the medal solenoid of the no-operation command is in the ON state (step S227). . Specifically, the sub CPU 102 refers to the no-operation command storage area in which the most recent no-operation command received from the main control circuit 91 is stored, and sets the ON / OFF state of the medal solenoid 208 included in the no-operation command. It is determined whether or not the medal solenoid is in the ON state based on the above information. Note that the no-operation command storage area is provided in the sub RAM 103 as described above.

  If it is determined in step S227 that the medal solenoid is not in the ON state (if step S227 is NO), the sub CPU 102 ends the medal selector command transmission processing. On the other hand, if it is determined in step S227 that the medal solenoid is in the ON state (if step S227 is YES), the sub CPU 102 transmits an insertion state (possible) command (step S228). Specifically, the sub CPU 102 transmits an insertion state command in which the value of DAT0 is “1” (acceptable) to the medal selector 201. Here, the insertion state (possible) command is transmitted to the medal selector 201 after being encrypted with the encryption key.

  Next, the sub CPU 102 sets a medal acceptance flag to a medal acceptance flag (step S229). Specifically, the sub CPU 102 sets “1” (acceptable) in the medal acceptance flag storage area of the sub RAM 103. Then, the sub CPU 102 ends the medal selector command transmission processing.

  If it is determined in step S226 that the medal reception flag indicates that the medal cannot be received (step S226 is NO), the sub CPU 102 determines whether the medal solenoid of the no-operation command is in the OFF state (step S230). Specifically, the sub CPU 102 refers to the no-operation command storage area in which the most recent no-operation command received from the main control circuit 91 is stored, and sets the ON / OFF state of the medal solenoid 208 included in the no-operation command. It is determined whether or not the medal solenoid is in the OFF state based on the above information.

  If it is determined in step S230 that the medal solenoid is not in the OFF state (if step S230 is NO), the sub CPU 102 terminates the medal selector command transmission processing. On the other hand, when it is determined in step S230 that the medal solenoid is in the OFF state (when step S230 is determined to be YES), the sub CPU 102 transmits an insertion state (impossible) command (step S231). Specifically, the sub CPU 102 transmits an insertion state command in which the value of DAT0 is “0” (cannot be accepted) to the medal selector 201. Here, the insertion state (impossible) command is transmitted to the medal selector 201 after being encrypted with the encryption key.

  Next, the sub CPU 102 sets a medal acceptance flag to a medal acceptance flag (step S232). Specifically, the sub CPU 102 sets “0” (cannot be accepted) in the medal acceptance flag storage area of the sub RAM 103. Then, the sub CPU 102 ends the medal selector command transmission processing.

  As described above, the encryption key provided from the computer 400 to the medal selector 201 is used for encrypting command data in data communication (command transmission / reception) between the medal selector 201 and the sub-control circuit 101. Used for Therefore, the same encryption key as the encryption key stored in the medal selector 201 is held in the sub-control circuit 101 as well. The encryption key can be stored in a predetermined storage unit of the sub-control circuit 101 by various methods. For example, similarly to the initialization processing of the medal selector 201 of the present invention, it is also possible to connect to the computer 400 and provide the encryption key from the computer 400.

  The initialization vector is randomly generated at each encryption to prevent the data encrypted with the same encryption key from being the same when the data to be encrypted is the same. When the same encryption target data is encrypted with the same encryption key by combining this initialization vector with the data to be encrypted and encrypting it or by combining it with the encrypted data. Even so, different encrypted data will be generated, and as a result, the strength of encryption can be increased. In the present embodiment, such an initialization vector is provided from the computer 400 to the medal selector 201 together with the encryption key. However, when not used by the medal selector 201, the initialization data is transmitted from the computer 400 to the medal selector 201. Can be configured not to be provided.

  With the configuration of the present embodiment described above, the medal selector 201 can perform data communication with both the external computer (computer 400) and the sub-control circuit 101 using the same protocol only by switching the connection destination of the cable 280. it can. Therefore, there is no need to perform an operation of changing the setting of the medal selector 201 in accordance with the connected hardware, and the connection destination hardware can be easily switched. The medal selector 201 can switch processing depending on the type of a command received from the hardware of the connection destination, and the computer 400 and the sub-control circuit 101 that are the connection destinations can receive the command from the medal selector 201, respectively. I have.

  With the above-described configuration, the medal selector 201 receives an encryption key from an external computer (computer 400) as initialization processing, and the encryption key is encrypted with a predetermined encryption key. In such a case, the encryption key can be distributed more safely.

  In addition, since the medal selector encryption key creation tool creates an encryption key file that encrypts and stores the encryption key, the encryption key can be easily created, and the created encryption key can be safely stored and stored. Can be managed.

  Further, as described above, since the data communication between the medal selector 201 and the sub control circuit 101 is encrypted by the encryption key (that is, the two-way communication by the encrypted communication data is realized), Security between the selector 201 and the sub-control circuit 101 can be maintained at a high level.

  In the present embodiment, the command between the medal selector 201 and the sub-control circuit 101 and the command between the medal selector 201 and the computer 400 include a 2-byte transmission counter (CNT) and DAT0 to DAT6. It is configured to include parameters (data part). Here, for example, when one data is transmitted by a plurality of commands, the receiving side waits until all parameters of the series of commands are received in the reception buffer. It can be configured to be integrated into one piece of data and to decrypt that data with an encryption key. Further, in the present embodiment, the data representing the command type is not encrypted using the encryption key, and the receiving side decrypts the transmission counter and DAT0 to DAT6 with the encryption key after determining the command type. However, encryption using an encryption key including data representing a command type can also be performed. In this case, decryption including data representing a command type is performed on the receiving side.

<GUI of the door monitoring unit encryption key creation tool>
Next, a GUI of a door monitoring unit encryption key creation tool (program) for creating an encryption key of the 24h door monitoring unit 63 will be described with reference to FIGS. 34 and 35.

  The door monitoring unit encryption key creation tool is executed on the computer 400 as described above, and the screen of the tool is displayed on the display 409 of the computer 400, and inputs and instructions are input using the keyboard 411, the mouse 412, and the like. Done.

  FIG. 34A shows an encryption key creation screen 601 of the door monitoring unit encryption key creation tool. The encryption key creation screen 601 includes a creation display unit 602 controlled to be displayed on the front by selecting a creation tab. The creation display unit 602 includes an encryption key input unit 603 and a checksum display unit 605. , A creation date / time display unit 606, and a creation instruction button 607. FIG. 34A shows an encryption key creation screen 601 before an encryption key is input.

  FIG. 34B shows the same encryption key creation screen 601 as FIG. 34A, but here, the user has entered the encryption key into the encryption key input unit 603. Here, the user presses the creation instruction button 607 with the mouse 412 (arrow 608) to instruct creation of an encryption key file.

  When inputting an encryption key into the encryption key input unit 603, the user inputs 16 characters, for example, as ASCII code characters into the encryption key input unit 603. The key manager sets one encryption key for each or a group of the 24h door monitoring units 63, and stores the encryption key separately in the form of, for example, a text file. . In addition, a text file storing the encryption key can be dragged and dropped (or text copied and pasted) into the encryption key input unit 603 to input 16 characters.

  In FIG. 34B, the state in which the encryption key has been input to the encryption key input section 603 is displayed as 16 “a” for convenience, but the 16 input keys are input to the encryption key input section 603. The character may be displayed as it is, or may be hidden by a character such as "*" together with the input.

Next, a communication format between the 24h door monitoring unit 63 and the host device will be described with reference to FIG. FIG. 43 is a diagram for explaining a communication format between the 24h door monitoring unit 63 and the host device, FIG. 43A is a diagram for explaining an outline of the communication format, and FIG. FIG. 9 is a diagram illustrating an example of a form of communication data when a random number is transmitted from a unit 63 to a host device.

  As shown in FIG. 43A, in the present embodiment, communication data is transmitted in the form of an ASCII code. At the beginning of the communication data, STX (Start of TeXt), which is a control character indicating the start of a text portion in the communication message, is arranged. Information (TEXT) transmitted and received by communication is arranged behind the STX. Behind TEXT, an ETX (End of TeXt), which is a control character indicating the end of the text portion in the communication message, is arranged. After the ETX, a two-digit sum value based on the total value of the TEXT values is arranged. Therefore, the communication data in the present embodiment is composed of 1 byte of STX, 0 to 52 bytes of TEXT (depending on information transmitted and received), 1 byte of ETX, and 2 bytes of sum value.

  The communication format shown in FIG. 43A is used not only when a command is transmitted from the host device to the 24h door monitoring unit 63, but also when the 24h door monitoring unit 63 returns a response to the host device in response to the command transmitted from the host device.

ASCII code is placed. An ASCII code corresponding to ETX (03H) and an ASCII code corresponding to the sum value are arranged behind the 8-digit ASCII code corresponding to the random number value “12345678”. Is arranged.

<Sequence>
Next, a sequence for defining a command transmission order will be described with reference to FIG. The sequence is defined for each processing pattern, and each is stored in the sequence table. The sequence table is stored in a non-volatile storage device of the host device, for example, in the ROM cartridge substrate 86 when the host device is the sub-control board 72, and in a hard disk or the like when the host device is a setting device (for example, the computer 400). It is remembered.

  The sequence table defines a plurality of sequences. The sequence consists of at least one general command or privileged command. When a sequence is executed in a predetermined process performed by the host device, a command constituting the sequence is transmitted from the host device to the 24h door monitoring unit 63. When there are a plurality of commands constituting a sequence, the sequence table also defines the transmission order of the commands. In any of the sequences, the host device transmits the command in the rear sequence in the sequence after receiving the answer and information corresponding to the command in the front sequence from the 24h door monitoring unit 63.

  The sequence table includes, for example, a connection confirmation sequence, an initialization sequence, a setting reading sequence, a startup sequence, a first state detection sequence, a history acquisition sequence, a whole history acquisition sequence, a clock set sequence, a monitoring interval time setting sequence, and a recording start time. A setting sequence is specified. Further, a recording mode setting sequence, a secret key setting sequence, a batch setting sequence, a second state detection sequence, and the like are defined.

  The connection confirmation sequence is a sequence executed when a connection confirmation instruction is issued by the door monitoring unit initialization tool executed by the computer 400 according to the present embodiment. For example, a serial ID command (CR) is To the door monitoring unit 63 for 24 h.

  The initialization sequence is a sequence that is executed when an initialization instruction is issued by the door monitoring unit initialization tool executed by the computer 400 according to the present embodiment. For example, a random number command (CK) and a login command ( CI), an initialization command (SI), a secret key setting command (SW), a recording start time setting command (SB), and a clock set command (ST) are transmitted to the 24h door monitoring unit 63 in this order.

  The setting reading sequence is a sequence executed when a setting reading instruction is issued by the door monitoring unit setting reading tool executed by the computer 400 according to the present embodiment. For example, a version request command (CV), a serial ID command (CR), a clock read request command (CT), a status read command (CS), an open / close history information count command (CC), a latest number command (CN), and an open / close history information read command (CB) in the order of 24h. This is transmitted to the door monitoring unit 63.

  Similarly, for other sequences such as an activation sequence, the contents of the command and the transmission order of the command are defined.

<Connection confirmation and initialization sequence using the door monitoring unit initialization tool>
Next, when connection confirmation and initialization are instructed in the door monitoring unit initialization tool executed by the computer 400, the transmission order of the command transmitted to the door monitoring unit 63 for 24h based on the above sequence is determined. The processing will be described with reference to FIG.

  In this process, the computer 400 executes the connection confirmation sequence by referring to the sequence table, and then executes the initialization sequence when the initialization is instructed.

  First, the computer 400 transmits a serial ID command (CR) to the 24h door monitoring unit 63 according to the connection confirmation sequence. The 24h door monitoring unit 63 that has received the serial ID command transmits (replies) the serial ID stored in the EEPROM 305 to the computer 400. As a result, the door monitoring unit initialization tool of the computer 400 determines that the connection to the 24h door monitoring unit 63 has been established due to the acquisition of the serial ID, and displays connection OK on the connection confirmation result display unit 625 (FIG. 36B). reference).

  Next, the computer 400 transmits a random number command (CK) to the 24h door monitoring unit 63 according to the initialization sequence. The 24h door monitoring unit 63 that has received the random number command generates a random number and transmits (replies) the generated random number value to the host device.

  Also, the 24h door monitoring unit 63 stores the generated random number value in the random number storage area of the RAM 304.

To generate a password. Then, the generated password is stored in the password storage area of the RAM 304.

  On the other hand, upon receiving the random number value from the 24h door monitoring unit 63, the computer 400 generates a password from the received random number value and the stored initial secret key. Note that the same secret key as the initial value secret key stored in the EEPROM 305 is stored in the computer 400 in advance.

  Next, the computer 400 transmits a login command (CI) to the 24h door monitoring unit 63. The login command includes the password generated by the computer 400.

  The 24h door monitoring unit 63 that has received the login command from the computer 400 determines whether or not the password included in the login command matches the password stored in the password storage area of the RAM 304. If it does not match (OK) and does not match, it sends (replies) an answer to the effect that login is not permitted (NG).

  When the computer 400 receives an answer indicating that login is not permitted from the 24h door monitoring unit 63, the computer 400 displays “initialization NG” on the status display unit 629 on the initialization instruction screen 621 in FIG. 36B. When receiving the answer to the effect that the login is permitted from the 24h door monitoring unit 63, the computer 400 transmits an initialization command (SI) to the 24h door monitoring unit 63 in order to reset the 24h door monitoring unit 63.

  The 24h door monitoring unit 63 that has received the initialization command clears the monitoring interval time and the recording start time stored in the EEPROM 305. Then, an answer indicating whether the result of the initialization command is OK or NG is transmitted to the computer 400.

  When the computer 400 receives the NG answer from the 24h door monitoring unit 63, the computer 400 displays “Initialization NG” on the status display unit 629 on the initialization instruction screen 621 in FIG. 36B. When receiving the OK answer from the 24h door monitoring unit 63, the computer 400 transmits a secret key setting command (SW) to the 24h door monitoring unit 63. The secret key setting command includes a secret key according to the change, which is an encryption key obtained by decryption from the encryption key file.

  The 24h door monitoring unit 63 that has received the secret key setting command stores (overwrites) the secret key included in the secret key setting command in the secret key storage area of the EEPROM 305. Then, an answer indicating whether the result of the secret key setting is OK or NG is transmitted to the computer 400.

  When the computer 400 receives the NG answer from the 24h door monitoring unit 63, the computer 400 displays “Initialization NG” on the status display unit 629 on the initialization instruction screen 621 in FIG. 36B. When an OK answer is received from the 24h door monitoring unit 63, the computer 400 transmits a recording start time setting command (SB) to the 24h door monitoring unit 63.

  The 24h door monitoring unit 63 that has received the recording start time setting command stores (overwrites) the recording start time included in the recording start time setting command in the recording start time storage area of the EEPROM 305. Then, the recording start time setting answer is transmitted to the computer 400.

  Next, the computer 400 transmits a clock setting command (ST) to the 24h door monitoring unit 63. The 24h door monitoring unit 63 that has received the clock set command, based on the information indicating the year, month, day, hour, minute, second, and day of the week included in the clock set command, sets the year, month, day, hour, and minute of the RTC 301. , Seconds, and days of the week. Then, the date and time set answer is transmitted to the computer 400.

  In the initialization command (SI), the monitoring interval time and the recording start time stored in the EEPROM 305 are cleared, and thereafter, the monitoring interval time setting command (SA) and the recording start time setting command (SB) are changed. Although the 24h door monitoring unit 63 should be transmitted, the description of the monitoring interval time setting command (SA) is omitted in the example of the initialization sequence shown in FIG.

  In the initialization sequence, as shown in FIG. 44, the computer 400 transmits a login command (CI) to the 24h door monitoring unit 63 so as to request various settings based on the privileged command, and performs login. A description of a logout command (CO) required for this login is omitted.

  In the present embodiment, a random number is exchanged between the 24h door monitoring unit 63 and the computer 400, and this random number and an initial secret key (or a secret key (encryption key) stored in place of the initial secret key) are exchanged. Thus, the 24h door monitoring unit 63 is configured to generate a login password that enables the use of the privileged command. However, without exchanging random numbers, for example, the encryption key itself is used as the login password. It can be designed as follows.

<Sequence of setting reading by door monitoring unit initialization tool>
Next, regarding the transmission order and processing of the command transmitted to the 24h door monitoring unit 63 based on the above sequence, when the setting reading instruction is performed in the door monitoring unit setting reading tool executed by the computer 400, This will be described with reference to FIG.

  In this process, the computer 400 executes a setting reading sequence with reference to the sequence table.

  First, the computer 400 transmits a status read command (CS) to the 24h door monitoring unit 63 according to the setting read sequence. The 24h door monitoring unit 63, which has received the status read command, sets the opening / closing history information stored in the first detection result storage area of the RAM 304, the self-diagnosis check result stored in the EEPROM 305, the final communication history, and the normal mode setting. Then, a status answer including a value such as a door setting is transmitted to the computer 400 (reply).

  Next, the computer 400 transmits a serial ID command (CR) to the 24h door monitoring unit 63. The 24h door monitoring unit 63 that has received the serial ID command transmits (replies) the serial ID stored in the EEPROM 305 to the computer 400 as a serial ID answer. As a result, the door monitoring unit setting reading tool of the computer 400 controls to display the acquired serial ID in the serial ID display area of the setting value display unit 656.

  Thereafter, similarly, a command is transmitted from the computer 400 to the 24h door monitoring unit 63, and corresponding setting values and the like are obtained from the RAM 304 and the EEPROM 305, and transmitted to the computer 400.

  The setting reading sequence shown in FIG. 45 includes an entire history acquisition sequence. The entire history acquisition sequence includes an opening / closing history information count command (CC), a latest number command (CN), and an opening / closing history information read command. The computer 400 specifies the number of the opening / closing history information storage area (of the EEPROM 305) from which the opening / closing history information is to be acquired, based on the received number of opening / closing history information and the latest number.

  Then, the computer 400 repeats the transmission of the open / close history information read command (CB) until the open / close history information storage area is obtained from all the open / close history information storage areas numbered with the specified open / close history information storage area (loop). ).

  As a result, the door monitoring unit setting reading tool executed by the computer 400 displays a setting display screen 651 as shown in FIG.

The input encryption key may be displayed as it is on the encryption key input unit 503, or may be converted to another character when input. You may do so.

  Next, in step S302, a checksum is calculated based on the input encryption key, and the calculated checksum value is displayed on the checksum display section 605 of the encryption key creation screen 601 shown in FIG. 34B.

  Next, in step S303, it is determined whether or not a creation button for instructing creation of an encryption key file (the creation instruction button 607 of the encryption key creation screen 601 shown in FIG. 34B) is pressed. If the create button has not been pressed (NO in step S303), the process returns to step S303, and this process is repeated.

  If the create button has been pressed (YES in step S303), in step S304, the encryption key is encrypted to create an encryption key file. The encryption key file is, for example, a file in an XML format, and can include an encrypted encryption key, a check sum value, and a creation date and time.

  Next, in step S305, the created encryption key file is stored in a predetermined storage medium (for example, an external storage device 413 including a hard disk or a semiconductor memory, or an external storage medium 430 such as a portable flash memory). Then, in step S306, a message indicating that the creation of the encryption key file has been completed is displayed in a predetermined area of the encryption key creation screen 601 shown in FIG. 34B.

<Process of door monitoring unit initialization tool>
Next, an example of the initialization processing of the door monitoring unit initialization tool executed in the external computer (computer 400) will be schematically described with reference to the flowchart in FIG.

  First, in step S321, it is determined whether or not a command answer has been received from the 24h door monitoring unit 63. If a command answer has been received (YES in step S321), it is determined in step S322 whether the received answer is a “serial ID answer”. If the reception answer is “serial ID answer” (YES in step S322), the connection flag is turned on in step S323. In this case, for example, control is performed to display “connection OK” on the connection confirmation result display section 625 of the initialization instruction screen 621 shown in FIG. 36B. After the process in step S323, the process returns to the determination in step S321.

  If the received answer is not the “serial ID answer” (NO in step S322), it is determined in step S324 whether the received answer is a “random number answer”. If the received answer is a “random answer” (YES in step S324), in step S325, a login password is generated based on the received random number and the initial secret key. Thereafter, a login command including the login password is transmitted to the 24h door monitoring unit 63 according to the initialization sequence (step S326). After the process in step S326, the process returns to the determination in step S321.

  If the received answer is not a “random answer” (NO in step S324), it is determined in step S327 whether the received answer is a “login answer”. If the received answer is “login answer” (YES in step S327), in step S328, it is determined whether or not the content of the answer is a login permission. If the answer does not indicate that the login is permitted (NO in step S328), control is performed so that “connection NG” is displayed on the connection confirmation result display section 625 of the initialization instruction screen 621 shown in FIG. 36B. After the process in step S329, the process returns to the determination in step S321.

  On the other hand, if the contents of the answer are log-in permission (YES in step S328), the secret key setting command including the encryption key file (encryption key) decrypted in step S338 in step S330 according to the initialization sequence. Is transmitted to the 24h door monitoring unit 63 (step S326). When the answer to the secret key setting command (secret key setting answer) is NG, control is performed so that “connection NG” is displayed on the connection confirmation result display section 625 of the initialization instruction screen 621 shown in FIG. 36B. Here, it is omitted.

  After the processing in step S330, the recording start time setting command is transmitted to the 24h door monitoring unit 63 (step S331), and then the clock setting command is transmitted to the 24h door monitoring unit 63 (step S332). Here, the initialization of the 24h door monitoring unit 63 is completed normally, and in step S333, control is performed so as to display “connection OK” on the connection confirmation result display section 625 of the initialization instruction screen 621 shown in FIG. 36B. If the reception answer is not the “login answer” (NO in step S327), or after the processing in step S323, the process returns to the determination in step S321.

  If the answer has not been received from the 24h door monitoring unit 63 (NO in step S321), the process proceeds to step S334, where the door monitoring unit initialization tool uses a connection confirmation instruction (connection on the initialization instruction screen 621 shown in FIG. 36A). It is determined whether or not the confirmation button 624 has been pressed). If the connection confirmation instruction has been given (YES in step S334), a serial ID command is transmitted to the 24h door monitoring unit 63 according to the connection confirmation sequence in step S335. After the process in step S335, the process returns to the determination in step S321.

  If the connection confirmation instruction has not been issued (NO in step S334), the process proceeds to step S336, and it is determined whether or not a file reading instruction regarding the encryption key file has been issued in the door monitoring unit initialization tool. The file reading instruction is, for example, an instruction to display a file reading instruction screen on an initialization menu screen (not shown) before the initialization instruction screen 621 of the door monitoring unit initialization tool shown in FIG. 36A is displayed. This is performed by specifying an encryption key file to be used for initialization on the displayed file reading instruction screen.

  If a file reading instruction regarding the encryption key file is issued (YES in step S336), the specified encryption key file is read in step S337, and then the read encryption key file is decrypted in step S338. . After step S338, the process returns to the determination of step S321.

  If the file reading instruction for the encryption key file has not been issued (NO in step S336), in step S339, it is determined whether the door monitoring unit initialization tool has issued the initialization instruction, that is, the initialization button 628 (FIG. 36A). ) Is pressed. If an initialization instruction has been given (YES in step S339), it is determined in step S340 whether the connection flag is ON.

  When it is determined that the connection flag is ON (YES in step S340), that is, when the serial ID is normally received from the 24h door monitoring unit 63, in step S341, a random number command is generated based on the initialization sequence. Transmit to the door monitoring unit 63 for 24h. After step S341, the process returns to the determination of step S321.

  If it is not determined that the connection flag is ON (NO in step S340), it is determined that the connection with the 24h door monitoring unit 63 has not been normally established, and the door monitoring unit initialization tool issues an error message to that effect. It is displayed (step S342). After step S342, the process returns to step S321.

  In the example shown in FIG. 47, after the encryption key file created by the door monitoring unit encryption key creation tool is temporarily decrypted to obtain the original encryption key, the encryption key is used as described above. It is configured to be encrypted with another encryption key and transmitted to the door monitoring unit 63 for 24h.

  Also, it is assumed that the answer received from the 24h door monitoring unit 63 is also encrypted with the above-mentioned another encryption key, but in the flowchart of FIG. 47, the answer related to the answer (using another encryption key) is used. The decoding process is omitted.

  As described with reference to FIG. 44, the transmission processing of the monitoring interval time setting command (SA) and the reception processing of the answer, and the transmission processing of the logout command (CO) and the reception processing of the answer are also omitted here. .

<Various processes performed by the door monitoring unit>
Next, an example of processing executed in the 24h door monitoring unit 63 will be schematically described with reference to the flowchart in FIG. The 24h door monitoring unit 63 can execute the processing shown in FIG. 48 similarly when the sub-control circuit 101 is connected or when it is connected to the computer 400. It is also possible to control so as to perform processing according to each connection destination. When connected to the computer 400, the 24h door monitoring unit 63 performs a corresponding process according to the command received from the computer 400 based on the connection confirmation sequence, the initialization sequence, and the setting reading sequence as described above. Do.

[Door monitoring unit main processing]
First, the door monitoring unit main process performed by the control LSI 300 will be described with reference to FIG. FIG. 48 is a flowchart illustrating an example of the door monitoring unit main process according to the present embodiment.

  In the door monitoring unit main process, the control LSI 300 first performs a startup initialization process (step S401). In the startup initialization process, the control LSI 300 clears the count number corresponding to the monitoring interval time and the count number corresponding to the recording start time stored in the EEPROM 305. Further, the value of the monitoring interval counter and the value of the recording start time counter stored in the RAM 304 are cleared.

  Next, the control LSI 300 performs a port input process (step S402). In the port input process, the control LSI 300 acquires information indicating whether the front door 2b is in the open state or the closed state from the input port of the I / O port circuit 309, and stores the acquired information in the RAM 304.

  Next, the control LSI 300 performs a door monitoring process (step S403). In the door monitoring process, the control LSI 300 stores the opening / closing history information in the EEPROM 305. The specific contents of the door monitoring process will be described later with reference to FIG.

  Next, the control LSI 300 performs a receiving process (step S404). In the reception process, the control LSI 300 performs various processes in accordance with a command received from a host device (for example, the computer 400) in a reception interrupt process (see FIG. 52) described later. The specific contents of the reception processing will be described later with reference to FIG.

  Next, the control LSI 300 performs a transmission process (step S405). In the transmission process, the control LSI 300 transmits various answers to the host device. The specific contents of the transmission process will be described later with reference to FIG.

  Next, the control LSI 300 performs a periodic wait process (step S406). In the cyclic wait processing, the control LSI 300 determines whether or not 20 msec has elapsed from the previous cyclic wait processing. If not, the control LSI 300 suspends the transition to the next processing (step S407) until the elapse. Then, the process proceeds to step S407. Therefore, the process of adding 1 to the various counters in the various processes executed by the control LSI 300 is executed once every 20 msec. The process of adding 1 to various counters in the various processes executed by the control LSI 300 includes a step S408 described later of the door monitoring unit main process and a step S424 of the door monitoring process (see FIG. 49) described later.

  Next, the control LSI 300 refers to the recording start time counter storage area of the RAM 304 and the recording start time storage area of the EEPROM 305, and determines whether the value of the recording start time counter is less than the count number corresponding to the recording start time (step). S407). If it is determined in step S407 that the value of the recording start time counter is not less than the count number corresponding to the recording start time (if step S407 is NO), the control LSI 300 shifts the processing to step S402, and proceeds to step S402. Is repeated.

  On the other hand, if it is determined in step S407 that the value of the recording start time counter is less than the count number corresponding to the recording start time (if step S407 is YES), the control LSI 300 adds 1 to the value of the recording start time counter. (Step S408). Thereafter, the control LSI 300 shifts the processing to step S402 and repeats the processing from step S402.

[Door monitoring process]
Next, the door monitoring process in step S403 of the door monitoring unit main process (see FIG. 48) will be described with reference to FIG. FIG. 49 is a flowchart illustrating an example of the door monitoring process according to the present embodiment.

  In the door monitoring process, the control LSI 300 first performs a door monitoring state detection process (step S421). In the door monitoring state detection processing, the control LSI 300 stores the state information stored in the input port information storage area of the RAM 304 in the first detection result storage area and the second detection result storage area. The specific contents of the door monitoring state detection processing will be described later with reference to FIG.

  Next, the control LSI 300 performs a door monitoring record determination process (step S422). In the door monitoring record determination process, the control LSI 300 determines whether the opening / closing history information can be stored in the EEPROM 305, and sets the recording permission flag to ON (sets “1”) when it is determined that recording is possible. . On the other hand, if it is determined that recording is not possible, the recording permission flag is set to OFF (cleared). The specific contents of the door monitoring record determination processing will be described later with reference to FIG.

  Next, the control LSI 300 determines whether or not the recording permission flag is set to ON (“1” is set) (step S423). If it is determined in step S423 that the recording permission flag is set to OFF (if step S423 is NO), the control LSI 300 ends the door monitoring process, and proceeds to the door monitoring unit main process (see FIG. 48). Return to step S404).

  On the other hand, if it is determined in step S423 that the recording permission flag is set to ON (if step S423 is YES), the control LSI 300 determines whether the monitoring interval counter stored in the monitoring interval counter storage area of the RAM 304 has been set. One is added to the value (step S424).

  Next, the control LSI 300 determines whether or not the value of the monitoring interval counter of the RAM 304 is equal to or greater than the count number corresponding to the monitoring interval time stored in the monitoring interval time storage area of the EEPROM 305 (step S425). When it is determined in step S425 that the value of the monitoring interval counter is less than the count number corresponding to the monitoring interval time (if step S425 is NO), the control LSI 300 ends the door monitoring process and returns the process to the door monitoring unit main processing. The process returns to step S404 of the process (see FIG. 48).

  On the other hand, when it is determined in step S425 that the value of the monitoring interval counter is equal to or greater than the count number corresponding to the monitoring interval time (in the case of YES determination in step S425), the control LSI 300 sets (clears) 0 to the monitoring interval counter. (Step S426).

  Next, the control LSI 300 determines whether or not the state change flag stored in the state change flag storage area of the RAM 304 is set to ON (step S427). The state change flag is set to ON in step S446 of a door monitoring state detection process (see FIG. 50) described later. When it is determined in step S427 that the state change flag is set to OFF (NO in step S427), the control LSI 300 ends the door monitoring process, and proceeds to the door monitoring unit main process (see FIG. 48). Return to step S404).

  On the other hand, when it is determined in step S427 that the state change flag is set to ON (when the determination in step S427 is YES), the control LSI 300 determines that the latest number stored in the latest number storage area of the EEPROM 305 is 128 or more. It is determined whether or not this is the case (step S428).

  If it is determined in step S427 that the latest number stored in the latest number storage area of the EEPROM 305 is 128 or more (YES in step S428), the control LSI 300 stores the latest number in the latest number storage area of the EEPROM 305 as the latest number. "1" is set (step S429). Then, the control LSI 300 shifts the processing to step S431.

  In step S427, when it is determined that the latest number stored in the latest number storage area of the EEPROM 305 is less than 128 (NO in step S428), the control LSI 300 sets the value of the latest number storage area of the EEPROM 305 to " "1" is added (step S430). Then, the control LSI 300 shifts the processing to step S431.

  In the process of step S431, the control LSI 300 determines whether or not the history counter stored in the history counter storage area of the EEPROM 305 is less than 128 (step S431). In the process of step S431, when it is determined that the history counter is less than 128 (when step S431 is YES), the control LSI 300 adds 1 to the history counter (step S432). Then, the control LSI 300 shifts the processing to step S433.

  On the other hand, when it is determined in step S431 that the history counter is not less than 128 (when step S431 is NO), the control LSI 300 shifts the processing to step S433.

  In the processing of step S433, the control LSI 300 stores the open / close history information stored in the second detection result storage area of the RAM 304 in the open / close history information storage area with the latest number stored in the latest number storage area of the EEPROM 305. Is stored.

  Next, the control LSI 300 sets the state change flag stored in the state change flag storage area of the RAM 304 to OFF (step S434). Then, the control LSI 300 ends the door monitoring process, and returns the process to step S404 of the door monitoring unit main process (see FIG. 48).

[Door monitoring status detection processing]
Next, the door monitoring state detection processing in step S421 of the door monitoring processing (see FIG. 49) will be described with reference to FIG. FIG. 50 is a flowchart illustrating an example of the door monitoring state detection process according to the present embodiment.

  In the door monitoring state detection processing, the control LSI 300 firstly stores state information (information indicating whether the door is open or closed) in the opening / closing history information stored in the first detection result storage area of the RAM 304 and an input port information storage area of the RAM 304. It is determined whether or not the status information stored in the storage device is different from the status information (step S441).

  In step S441, when it is determined that the state information of the first detection result storage area and the state information of the input port information storage area are not different (match) (if step S441 is NO), the control LSI 300 The door monitoring state detection process ends, and the process returns to step S422 of the door monitoring process (see FIG. 49).

  If it is determined in step S441 that the state information of the first detection result storage area is different from the state information of the input port information storage area (if step S441 is YES), the control LSI 300 returns the current time from the RTC 301 to the current time. The date and time information is acquired, and the open / close history information including the acquired date and time information and the status information of the input port information storage area is stored in the first detection result storage area (step S442).

  Next, the control LSI 300 determines whether or not the state change flag stored in the state change flag storage area of the RAM 304 has been set to OFF (step S443). When it is determined in step S443 that the state change flag is not set to OFF (when the determination in step S443 is NO), the control LSI 300 ends the door monitoring state detection processing and proceeds to the door monitoring processing (see FIG. 49). Return to step S422).

  On the other hand, when it is determined in step S443 that the state change flag is set to OFF (if step S443 is YES), the control LSI 300 assigns the latest number stored in the latest number storage area of the EEPROM 305. It is determined whether or not the status information of the opening / closing history information stored in the opened / closed history information storage area and the status information of the input port information storage area are different (step S444).

  In the process of step S444, it is determined that the state information of the opening / closing history information stored in the opening / closing history information storage area with the latest number and the state information of the input port information storage area do not differ (match). At this time (when step S444 is NO), the control LSI 300 ends the door monitoring state detection processing, and returns the processing to step S422 of the door monitoring processing (see FIG. 49).

  On the other hand, when it is determined in the process of step S444 that the state information of the opening / closing history information stored in the opening / closing history information storage area with the latest number is different from the state information of the input port information storage area (step S444). If S444 is YES), the control LSI 300 acquires the date and time information of the current time from the RTC 301, and stores the opening and closing history information including the acquired date and time information and the state information of the input port information storage area in the second detection result storage area. (Step S445).

  Next, the control LSI 300 sets the state change flag stored in the state change flag storage area of the RAM 304 to ON (step S446). Then, the control LSI 300 ends the door monitoring state detection processing, and returns the processing to step S422 of the door monitoring processing (see FIG. 49).

[Door monitoring record judgment processing]
Next, the door monitoring record determination process in step S422 of the door monitoring process (see FIG. 49) will be described with reference to FIG. FIG. 51 is a flowchart illustrating an example of the door monitoring record determination process according to the present embodiment.

  In the door monitoring record determination process, the control LSI 300 first refers to the recording mode storage area of the EEPROM 305 and determines whether the recording mode is set to the constant recording mode (step S451). In the process of step S451, when it is determined that the recording mode is not set to the continuous recording mode (when step S451 is NO), the control LSI 300 shifts the process to step S454 described below.

  In the process of step S451, when it is determined that the recording mode is set to the continuous recording mode (when step S451 is YES), the control LSI 300 stores the recording start time counter storage area of the RAM 304 and the recording start time storage of the EEPROM 305. With reference to the area, it is determined whether or not the value of the recording start time counter is equal to or greater than the count number corresponding to the recording start time (step S452). If it is determined in step S452 that the value of the recording start time counter is not equal to or greater than the count corresponding to the recording start time (if step S452 is NO), the control LSI 300 shifts the processing to step S454 described below.

  In step S452, when it is determined that the value of the recording start time counter is equal to or greater than the count number corresponding to the recording start time (when step S452 is YES), control LSI 300 is stored in the recording permission flag storage area of RAM 304. The recording permission flag is set to ON (step S453). Then, the control LSI 300 ends the door monitoring record determination process, and returns the process to step S423 of the door monitoring process (see FIG. 49).

  In step S454, the control LSI 300 sets the recording permission flag stored in the recording permission flag storage area of the RAM 304 to OFF (step S454). Then, the control LSI 300 ends the door monitoring record determination process, and returns the process to step S423 of the door monitoring process (see FIG. 49).

[Reception interrupt processing]
Next, a reception interrupt process executed by the control LSI 300 every time the serial communication circuit 307 of the control LSI 300 receives a command or data of one byte from the host device will be described with reference to FIG. FIG. 52 is a flowchart illustrating an example of the reception interruption process according to the present embodiment.

  In the reception interrupt processing, the control LSI 300 first determines whether or not the received data is “STX” (step S461). If it is determined in step S461 that the received data is “STX” (if step S461 is YES), the control LSI 300 determines whether the value of the reception counter stored in the reception buffer and the reception counter storage area of the RAM 304 is “1” is set, and the ETX reception flag stored in the ETX reception flag storage area of the RAM 304 is set to OFF (step S462). Then, the control LSI 300 ends the reception interrupt processing.

  On the other hand, if it is determined in step S461 that the received data is not “STX” (if step S461 is NO), the control LSI 300 returns to the reception buffer corresponding to the value of the reception counter stored in the reception counter storage area. (Step S463).

  Next, the control LSI 300 adds 1 to the value of the reception counter (Step S464). Next, the control LSI 300 determines whether or not the received data is “ETX” (step S465). When it is determined in step S465 that the received data is “ETX” (if step S465 is YES), the control LSI 300 sets the ETX reception flag stored in the ETX reception flag storage area of the RAM 304 to ON. . Further, the value of the sum counter of the RAM 304 is cleared (step S466). Then, the control LSI 300 ends the reception interrupt processing.

  On the other hand, if it is determined in step S465 that the received data is not “ETX” (NO in step S465), the control LSI 300 sets the ETX reception flag stored in the ETX reception flag storage area of the RAM 304 to ON. It is determined whether or not it has been performed (step S467). If it is determined in step S467 that the ETX reception flag is not set to ON (NO in step S467), the control LSI 300 ends the reception interrupt processing.

  If it is determined in step S467 that the ETX reception flag is set to ON (if step S467 is YES), 1 is added to the value of the sum counter (step S468).

  Next, the control LSI 300 determines whether or not the value of the sum counter is 2 (step S469). When it is determined in step S469 that the value of the sum counter is not 2 (when the determination in step S469 is NO), the control LSI 300 ends the reception interrupt processing. On the other hand, if it is determined in step S469 that the value of the sum counter is 2 (if step S469 is YES), the control LSI 300 turns on the reception completion flag stored in the reception completion flag storage area of the RAM 304. The setting is made (step S470), and the reception interruption process is ended.

[Reception processing]
Next, the reception processing in step S404 of the door monitoring unit main processing (see FIG. 48) will be described with reference to FIG. FIG. 53 is a flowchart illustrating an example of a reception process according to the present embodiment.

  In the reception process, the control LSI 300 first determines whether or not the reception completion flag stored in the reception completion flag storage area of the RAM 304 is set to ON (step S471). If it is determined in step S471 that the reception completion flag is not set to ON (if step S471 is NO), the control LSI 300 ends the reception processing and proceeds to the door monitoring unit main processing (see FIG. 48). Return to step S405.

  On the other hand, when it is determined in step S471 that the reception completion flag is set to ON (when the determination in step S471 is YES), the control LSI 300 refers to the reception buffer of the RAM 304, and receives the received sum value and the received data. Then, a consistency determination process is performed to determine whether or not is consistent (step S472). More specifically, in the consistency determination processing, the reception data (see FIG. 43A) stored in the reception buffer of the RAM 304 is sequentially added to the reception data in 1-byte units up to “ETX” excluding “STX” to obtain 1 byte. A byte sum value is calculated, and the calculation result is converted to an ASCII code to generate a 2-byte sum value. The generated sum value and the sum value stored in the reception buffer (SAM (ASCII 2)) to determine whether the received data is consistent. Note that, as a specific example of the consistency determination processing, an example in which a sum value is calculated by addition has been described. However, the present invention is not limited to this. Further, instead of calculating the sum value, the sum value may be determined by converting the sum value stored in the reception buffer from an ASCII code to a binary code.

  Next, as a result of the consistency determination processing in step S472, the control LSI 300 determines that the received sum value matches the received data, that is, determines whether the result of the consistency determination processing is OK. Is determined (step S473). If it is determined in step S473 that the result of the consistency determination process is not OK (if the determination in step S473 is NO), the control LSI 300 ends the reception process and proceeds to the door monitoring unit main process (see FIG. 48). It returns to step S405.

  On the other hand, if it is determined in step S473 that the result of the consistency determination processing is OK (if step S473 is YES), control LSI 300 determines whether the received command is a privileged command (step S473). S474). Specifically, the control LSI 300 refers to the reception buffer, and if the received data includes the ID of the privileged command (for example, SI, ST, SA, SB, SC, SW, etc.), the received command is It is determined that the command is a privileged command. If not included, it is determined that the command is not a privileged command.

  If it is determined in step S474 that the received command is not a privileged command (NO in step S474), control LSI 300 shifts the processing to step S477 described later. On the other hand, if it is determined in step S474 that the received command is a privileged command (YES in step S474), control LSI 300 sets the login flag stored in the login flag storage area of RAM 304 to ON. It is determined whether or not there is (step S475).

  If it is determined in step S475 that the log-in flag is not set to ON (NO in step S475), the control LSI 300 ends the reception processing and proceeds to the door monitoring unit main processing (see FIG. 48). It returns to step S405.

  On the other hand, when determining in step S475 that the login flag is set to ON (YES in step S475), control LSI 300 performs a privileged command reception process (step S476). In the process at the time of receiving the privileged command, the control LSI 300 performs various processes according to the received privileged command. The specific contents of the privileged command receiving process will be described later with reference to FIG. After the privileged command receiving process, the control LSI 300 ends the receiving process, and returns the process to step S405 of the door monitoring unit main process (see FIG. 48).

  Here, returning to the description of the processing of step S474, when it is determined that the received command is not a privileged command (when step S474 is NO), the control LSI 300 sets the login flag to OFF (step S477).

  Next, the control LSI 300 performs a general command receiving process (step S478). In the processing at the time of receiving a general command, the control LSI 300 performs various processing according to the received general command. The specific contents of the general command receiving process will be described later with reference to FIG. After the general command receiving process, the control LSI 300 ends the receiving process, and returns the process to step S405 of the door monitoring unit main process (see FIG. 48).

[Process when receiving privileged command]
Next, the process at the time of receiving the privileged command in step S476 of the reception process (see FIG. 53) will be described with reference to FIG. FIG. 54 is a flowchart illustrating an example of processing at the time of receiving a privileged command in the present embodiment.

  In the privileged command receiving process, the control LSI 300 first determines whether or not the received privileged command is an initialization command (step S481). The control LSI 300 refers to the reception buffer, and if the received data includes “SI”, which is the ID of the initialization command, determines that the privileged command is an initialization command and includes “SI”. If not, it is determined that the command is not an initialization command.

  If it is determined in step S481 that the received privileged command is an initialization command (if step S481 is YES), the control LSI 300 performs an initialization process (step S482). Thereafter, the control LSI 300 ends the privileged command receiving process.

  Thereafter, similarly, when each of the clock set command, the monitoring interval time setting command, the recording start time setting command, the recording mode setting command, and the secret key setting command is received, the corresponding control is performed (step S483 to step S492).

[Process when receiving general command]
Next, the general command receiving process in step S478 of the receiving process (see FIG. 53) will be described with reference to FIG. FIG. 55 is a flowchart illustrating an example of a process at the time of receiving a general command according to the present embodiment.

  In the general command receiving process, the control LSI 300 first determines whether or not the received general command is a serial ID command (step S501). The control LSI 300 refers to the reception buffer, and if the received data includes “CR”, which is the ID of the serial ID command, determines that the general command is a serial ID command and includes “CR”. If not, it is determined that the command is not a serial ID command.

  If it is determined in step S501 that the received general command is a serial ID command (if step S501 is YES), the control LSI 300 performs a serial ID command receiving process (step S502). In this process, the control LSI 300 acquires the serial ID stored in the serial ID storage area of the EEPROM 305. Thereafter, the control LSI 300 ends the processing at the time of receiving the general command.

  Thereafter, similarly, when a version request command, a random number command, a login command, a logout command, a clock read command, a latest number command, an open / close history information read command, an open / close history information count command, and a status read command are received, (Steps S503 to S520).

  Similarly, for other general commands, control is performed so as to determine what the received privileged command is, and to perform processing according to the determined privileged command.

[Sending process]
Next, the transmission processing in step S405 of the door monitoring unit main processing (see FIG. 48) will be described with reference to FIG. FIG. 56 is a flowchart illustrating an example of the transmission process according to the present embodiment.

  In the transmission process, the control LSI 300 first determines whether or not the reception completion flag stored in the reception completion flag storage area of the RAM 304 is set to ON (step S541). If it is determined in step S541 that the reception completion flag is not ON (if step S541 is NO), the control LSI 300 ends the transmission process and proceeds to step S406 of the door monitoring unit main process (see FIG. 48). return.

  On the other hand, when it is determined in step S541 that the reception completion flag is set to ON (when step S541 is determined to be YES). The control LSI 300 sets the reception completion flag to OFF (step S542).

  Next, the control LSI 300 determines whether or not the received command is a privileged command (Step S543). Specifically, the control LSI 300 refers to the reception buffer, and if the received data includes the ID of the privileged command (for example, SI, ST, SA, SB, SC, SW, etc.), the received command is It is determined that the command is a privileged command. If not included, it is determined that the command is not a privileged command.

  If it is determined in step S543 that the received command is a privileged command (YES in step S543), control LSI 300 performs privileged answer transmission processing (step S544). In the privilege answer transmission process, the control LSI 300 performs various transmission processes according to the received privilege command. The specific contents of the privilege answer transmission process will be described later with reference to FIG. Thereafter, the control LSI 300 ends the transmission processing, and returns the processing to step S406 of the door monitoring unit main processing (see FIG. 48).

  If it is determined in step S543 that the received command is not a privileged command (step S543 is NO), the control LSI 300 performs a general answer transmission process (step S545). In the general answer transmission process, the control LSI 300 performs various transmission processes according to the received general command. The specific contents of the general answer transmission process will be described later with reference to FIG. Thereafter, the control LSI 300 ends the transmission processing, and returns the processing to step S406 of the door monitoring unit main processing (see FIG. 48).

[Privilege answer transmission processing]
Next, the privilege answer transmission process in step S544 of the transmission process (see FIG. 56) will be described with reference to FIG. FIG. 57 is a flowchart illustrating an example of a privilege answer transmission process according to the present embodiment.

  In the privilege answer transmission process, the control LSI 300 first determines whether or not the received command is a secret key setting command (step S551). The control LSI 300 refers to the reception buffer of the RAM 304, and if the received data includes “SW” which is the ID of the secret key setting command, determines that the privileged command is the secret key setting command, and determines “SW”. Is not included, it is determined that the command is not a secret key setting command.

  If it is determined in step S551 that the received command is not the secret key setting command (if step S551 is NO), the control LSI 300 performs the process of step S555 described later. On the other hand, if it is determined in step S551 that the received command is a secret key setting command (if step S551 is YES), the control LSI 300 returns the secret key stored in the reception buffer, that is, the received secret key setting command. It is determined whether the secret key included in the command matches the secret key stored in the secret key storage area of the EEPROM 305 (step S552).

  If it is determined in step S552 that they match (step S552 is YES), a transmission process of transmitting an answer to the effect that the setting result is OK to the host device is performed (step S553). Then, the control LSI 300 ends the privilege answer transmission process.

  If it is determined in step S552 that they do not match (step S552 is NO), a transmission process of transmitting an answer to the effect that the setting result is NG to the host device is performed (step S554). Then, the control LSI 300 ends the privilege answer transmission process.

  Here, returning to the description of step S551, when it is determined that the received command is not the secret key setting command (if step S551 is NO), the control LSI 300 refers to the reception buffer of the RAM 304, and Is specified (step S555).

  Next, the control LSI 300 performs a transmission process (step S556) of transmitting an answer corresponding to the command specified in step S555 to the host device. Then, the control LSI 300 ends the privilege answer transmission process. In steps S553 and S554, an answer whose ID for the answer corresponding to the ID of the received privileged command includes “setting result OK” or “setting result NG” information is transmitted to the host device. However, in step S556, since there is no information corresponding to the answer ID, only the answer ID corresponding to the received privileged command ID is transmitted to the host device as the answer.

[General answer transmission processing]
Next, the general answer transmission processing in step S545 of the transmission processing (see FIG. 56) will be described with reference to FIG. FIG. 58 is a flowchart illustrating an example of general answer transmission processing according to the present embodiment.

  In the processing at the time of receiving a general command, the control LSI 300 first determines whether or not the received general command is a serial ID command (step S561). If it is determined in step S561 that the received general command is a serial ID command (YES in step S561), the control LSI 300 returns the serial ID command acquired in the serial ID command reception process (step S502 in FIG. 55). Is transmitted to the host device (step S562). After that, the control LSI 300 ends the general answer transmission process.

  Thereafter, similarly, when a version request command, a random number command, a login command, a logout command, a clock read command, a latest number command, an open / close history information read command, an open / close history information count command, and a status read command are received, (Steps S563 to S580).

<Door opening / closing monitoring process in sub-control circuit>
Next, as an example of a process performed by the sub control circuit 101 and the 24h door monitoring unit 63, a process performed when the sub control circuit 101 (sub control board 72) monitors the open / closed state of the front door 2b from the time of startup is described. This will be described with reference to FIG. FIG. 59 is a diagram illustrating an example of processing in which the sub-control circuit 101 transmits and receives commands between the 24h door monitoring unit 63 and the sub-control circuit 101 based on a sequence, and monitors the open / close state of the front door 2b. .

  At the beginning of this processing, the sub-control circuit 101 refers to the sequence table, executes a start-up sequence, and issues commands in the order of a version request command (CV), a serial ID command (CR), and a status read command (CS). Transmit to the door monitoring unit 63 for 24h.

  First, the sub control circuit 101 transmits a version request command (CV) to the 24h door monitoring unit 63 (C21). The 24h door monitoring unit 63 that has received the version request command transmits (replies) the program version stored in the EEPROM 305 to the host device (C22: version answer).

  Upon receiving the program version, the sub-control circuit 101 compares the received program version with the program version stored in the sub-SRAM 103b, which is a nonvolatile storage unit of the sub-control circuit 101. If they do not match, a second warning display process is performed. In the second warning display process, the sub control circuit 101 causes the display device of the sub control circuit 101 to display a screen indicating that login is not permitted. For example, the liquid crystal display device 11 displays a warning screen (not shown) in which a message “Program version is different” is arranged at the center of the screen.

  Further, upon receiving the program version, the sub control circuit 101 transmits a serial ID command (CR) to the 24h door monitoring unit 63 (C23). The 24h door monitoring unit 63 that has received the serial ID command transmits (replies) the serial ID stored in the EEPROM 305 to the sub control circuit 101 (C24: serial ID answer).

  Upon receiving the serial ID, the sub control circuit 101 compares the received serial ID with the serial ID stored in the sub SRAM 103b of the sub control circuit 101. If they do not match, a third warning display process is performed. The sub control circuit 101 displays a screen indicating that the 24h monitoring door monitoring unit has been replaced in the third warning display process. For example, on the liquid crystal display device 11, a warning screen in which a message “Monitoring unit has been replaced” is displayed at the center of the screen (not shown). At the lower part of the warning screen, the serial ID stored in the storage device of the sub control circuit 101 is displayed as "OLD UNIT SERIAL ID", and the received serial ID is displayed as "NEW UNIT SERIAL ID". .

  Further, upon receiving the serial ID, the sub control circuit 101 transmits a status read command (CS) to the 24h door monitoring unit 63 (C25). The 24h door monitoring unit 63 that has received the status read command transmits (replies) the opening / closing history information stored in the first detection result storage area of the RAM 304 to the sub control circuit 101 (C26: status answer).

  When the transmission of the command related to the start-up sequence ends, the sub-control circuit 101 refers to the sequence table, executes the entire history acquisition sequence, and executes the opening / closing history information count command (CC), the latest number command (CN), The command is transmitted to the 24h door monitoring unit 63 in the order of the read command (CB).

  First, the sub-control circuit 101 transmits an opening / closing history information count command (CC) (C27). The 24h door monitoring unit 63 that has received the opening / closing history information number command transmits the value of the history counter to the sub control circuit 101 (C28: opening / closing history information number answer).

  Next, the sub control circuit 101 transmits the latest number command (CN) (C29). The 24h door monitoring unit 63 that has received the latest number command transmits the latest number to the sub control circuit 101 (C28: latest number answer).

  The sub control circuit 101 compares the received latest number and the value of the history counter with the latest number stored in the sub SRAM 103b of the sub control circuit 101 and the value of the history counter. As a result of the comparison, if there is a difference, the number of the opening / closing history information storage area from which the opening / closing history information is acquired is specified based on the latest number and the value of the history counter. Then, the sub-control circuit 101 transmits an open / close history information read command (CB) specifying the open / close history information storage area to which the number of the specified open / close history information storage area is assigned (C31).

  The 24h door monitoring unit 63 that has received the opening / closing history information read command transmits (replies) the opening / closing history information stored in the opening / closing history storage area corresponding to the number included in the read command to the sub-control circuit 101 (C32: Opening / closing history information reading answer).

  Note that C31 and C32 are repeated until the opening / closing history information is acquired from all the opening / closing history information storage areas to which the number of the specified opening / closing history information storage area is assigned.

  When the transmission of the command related to the entire history acquisition sequence ends, the sub-control circuit 101 executes the first state detection sequence with reference to the sequence table, and reads the status read command (CS), the open / close history information number command (CC), The command is transmitted to the door monitoring unit 63 in the order of the latest number command (CN). Hereinafter, the first state detection sequence is executed at predetermined intervals, in this embodiment, every 500 msec.

  First, the sub control circuit 101 transmits a status read command (CS) to the 24h door monitoring unit 63 (C33). The 24h door monitoring unit 63 that has received the status read command transmits (replies) the opening / closing history information stored in the first detection result storage area of the RAM 304 to the sub control circuit 101 (C34: status answer).

  If the received opening / closing history information indicates that the front door 2b is open, the sub-control circuit 101 causes the liquid crystal display device 11 to display a screen (not shown) indicating that the front door 2b is open. (Door open display).

  Next, the sub-control circuit 101 transmits the opening / closing history information number command (CC) to the 24h door monitoring unit 63 (C35). The 24h door monitoring unit 63 that has received the opening / closing history information number command refers to the history counter storage area of the EEPROM 305 and transmits (replies) the value of the history counter to the host device (C35: opening / closing history information number answer). The sub-control circuit 101 that has received the history counter value compares the history counter value already stored in the sub-SRAM 103b of the sub-control circuit 101 with the received history counter value. The value of the history counter thus set is stored (overwritten) in the sub SRAM 103b.

  Next, the sub control circuit 101 transmits the latest number command (CN) to the 24h door monitoring unit 63 (C37). The 24h door monitoring unit 63 that has received the latest number command refers to the latest number storage area of the EEPROM 305 and transmits (replies) the latest number to the sub-control circuit 101 (C38: latest number answer). The sub control circuit 101 that has received the latest number compares the latest number already stored in the sub SRAM 103b of the sub control circuit 101 with the received latest number. (Overwrite).

  When the received latest number does not match the latest number stored in the sub SRAM 103b, the sub control circuit 101 executes a history acquisition sequence.

  The sub-control circuit 101 executes a history acquisition sequence and transmits an opening / closing history information read command (CB) to the 24h door monitoring unit 63. Note that this open / close history information read command includes the latest number stored in the sub SRAM 103b of the sub control circuit 101.

  The 24h door monitoring unit 63 that has received the opening / closing history information read command transmits (replies) the opening / closing history information stored in the opening / closing history storage area corresponding to the number included in the opening / closing history information reading command to the sub-control circuit 101. (C40: Opening / closing history information reading answer). Then, the sub-control circuit 101 that has received the opening / closing history information stores the received opening / closing history in the sub SRAM 103b.

  As described above, in the process of monitoring the open / closed state of the front door 2b from the time of activation, the sub-control circuit 101 sequentially executes the activation sequence, the entire history acquisition sequence, the first state detection sequence, and the history acquisition sequence. In each sequence, the sub-control circuit 101 transmits a command to the 24h door monitoring unit 63, and the 24h door monitoring unit 63 returns an answer to the sub-control circuit 101 in response to the received command. . That is, in this process, the sub control circuit 101 is the master (machine), and the 24h door monitoring unit 63 is the slave (machine).

<Process of door monitoring unit setting reading tool>
Next, an example of processing of the door monitoring unit setting reading tool executed in the external computer (computer 400) will be schematically described with reference to the flowchart in FIG.

  First, in step S601, it is determined whether the setting read button has been pressed. For example, the setting read button is the setting read button 652 displayed on the setting display screen 651 of the door monitoring unit setting read tool shown in FIG. When the setting read button is pressed (YES in step S601), in step S602, the door monitoring unit setting reading tool transmits all the commands of the setting reading sequence corresponding to the setting reading instruction to the 24h door monitoring unit 63. It is determined whether or not.

  If not all the commands of the setting reading sequence have been transmitted (NO in step S602), the next command is transmitted to the 24h door monitoring unit 63 based on the setting reading sequence in step S603. Next, in step S604, an answer corresponding to the transmitted command is received, and the received information is stored in a predetermined storage unit. After step S604, the process returns to step S602 to determine whether there is another command to be transmitted. Here, for simplicity, the process of transmitting a command and the process of receiving an answer to the transmitted command are collectively represented as steps S603 and S604.

  If all the commands in the setting reading sequence have been transmitted (YES in step S602), in step S605, the door monitoring unit setting reading shown in FIG. 37 is read based on the setting values and the like received by the answer corresponding to the transmitted command. The tool setting display screen 651 is edited. For example, information on version information, self-diagnosis check result, serial ID, current time, monitoring unit status, last communication history, normal mode setting, door setting, opening / closing history data number, latest opening / closing history data number, etc. is displayed in a corresponding display area. Perform editing processing to display in.

  Next, in step S606, the door monitoring unit setting reading tool displays the edited setting display screen 651 on the display 409 of the computer 400. This state is shown, for example, on the setting display screen 651 shown in FIG. After step S606, the process returns to step S601 to determine whether the setting read button has been pressed.

  If the setting read button has not been pressed (NO in step S601), it is determined in step S607 whether the validity verification button has been pressed. For example, the validity verification button is the set value validity verification button 654 displayed on the setting display screen 651 of the door monitoring unit setting reading tool shown in FIG. If the validity verification button has been pressed (YES in step S607), in step S608, the door monitoring unit setting reading tool checks the validity of the setting values and other information displayed on the setting display screen 651 according to a predetermined criterion. Determine gender.

  Then, in step S609, the setting display screen 651 is edited based on the determination result of the validity. For example, the background of a display area that displays information on version information and self-diagnosis check results is set to green when the information is determined to be valid, and to red when the information is determined to be invalid. .

  Next, in step S610, the door monitoring unit setting reading tool displays the edited setting display screen 651 on the display 409 of the computer 400. This state is shown, for example, on the setting display screen 651 shown in FIG. If the validity verification button has not been pressed (NO in step S607), or after step S610, the process returns to step S601 to determine whether the setting read button has been pressed.

  As can be seen from the setting display screen 651 shown in FIG. 38, like the self-diagnosis check result, the value read from the 24h door monitoring unit 63 indicates the diagnosis result (for example, either “normal” or “abnormal”). In this case, the door monitoring unit setting reading tool determines that “normal” is valid and the other “abnormal” is not valid. On the other hand, a predetermined threshold value is set for the monitoring interval time of the door setting, the recording start time, and the like, and the validity is determined based on the threshold value.

  As described above, in the setting display screen 651 of the door monitoring unit setting reading tool of the present embodiment, the background color in the display area of the setting values and the like changes according to the result of the validity verification. In addition, even when many items are displayed at once, invalid items can be easily and reliably found.

  The opening / closing history data for displaying a list of door opening / closing histories displayed on the setting display screen 651 is a door opening / closing history display section 658 when one of the history data or a predetermined number of errors has occurred. The door opening / closing history title display section 657, which is a representative area of, can be displayed with a green background color or a red background color according to the determination of validity. As described above, by changing the display mode of the title portion in accordance with the validity, even if there is an error in the history data that is not displayed (the history data that is not displayed unless scrolled down), that fact is removed. It can be surely grasped. At this time, the background color of the display line or the display item indicating the history data having an error can be individually changed at the same time.

  Further, in the door monitoring unit setting reading tool of the present embodiment, the information such as the operation record and the setting value displayed on the setting display screen 651 is displayed by selecting, for example, “File (F)” at the upper left of the setting display screen 651. , Can be output as a text file to a hard disk (external storage device 413) of the computer 400 and stored. Further, in addition to the information such as the operation record and the set value displayed on the setting display screen 651, together with the verification result of the validity, the text file is output to, for example, a hard disk (external storage device 413) of the computer 400 or the like. Can be. On the setting display screen 651, a display information save button, a display information & verification result save button, and the like can be arranged, and an operation menu can be prepared so that the user can instruct the output of such information.

  As described above, the encryption key provided from the computer 400 to the 24h door monitoring unit 63 is used to generate a password for logging in to the 24h door monitoring unit 63.

  With the configuration of the present embodiment described above, the 24h door monitoring unit 63 performs data communication with both the external computer (computer 400) and the sub-control circuit 101 using the same protocol simply by switching the connection destination of the cable 320. be able to. Therefore, there is no need to perform an operation of changing the setting of the 24h door monitoring unit 63 according to the connected hardware, and the connection destination hardware can be easily switched. The 24h door monitoring unit 63 can switch processing depending on the type of command received from the connected hardware, and the connected computer 400 and the sub-control circuit 101 also receive the answer from the 24h door monitoring unit 63, respectively. It is possible.

  Further, with the above-described configuration, the 24h door monitoring unit 63 receives the encryption key from the external computer (computer 400) as initialization processing, but in the communication between the 24h door monitoring unit 63 and the computer 400, When the encryption key is encrypted with a predetermined encryption key, the encryption key can be distributed more safely.

  In addition, since the encryption key file that encrypts and stores the encryption key is created by the door monitoring unit encryption key creation tool, the encryption key can be easily created and the created encryption key can be securely stored.・ Can be managed.

  In the present embodiment, the command between the 24h door monitoring unit 63 and the computer 400 is transmitted and received in a predetermined communication format, and the data is encrypted. Does not perform encryption using the encryption key, and the receiving side can determine the command type and then decrypt the data following the ID with the encryption key. Further, encryption using an encryption key including an ID indicating a command type can be performed. In this case, decryption including data indicating a command type is performed on the receiving side.

  The pachislot 1, the medal selector 201, the 24h door monitoring unit 63, the computer 400, and the like according to the embodiment of the present invention have been described so far by showing specific examples in which the present invention can be implemented. Are merely examples for explaining the present invention, and the scope of the present invention is not limited to these specific examples. The technical idea of the present invention can be realized by various other methods and configurations.

  In the above description of the embodiment, a pachislot machine has been described as an example of a gaming machine, but the present invention is not limited to this, and the technical idea of the present invention can be applied to other gaming machines other than pachislot machines. For example, the present invention can be applied to a pachinko machine, an enclosed game machine, or the like, and the encryption between the game medium identification device other than the medal selector and the game machine can be configured as described above.
