Embodiment 1 of the Invention
A gaming machine according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of a gaming machine (also called a slot machine or a revolving gaming machine).
A player who wants to enjoy a game with the slot machine 10 first borrows a medal as a game medium from a medal lending machine (not shown) or the like, and inserts a medal directly into the medal insertion slot 63 of the medal insertion device. The medal slot 63 is provided at a substantially central height on the front surface of the slot machine 10.

  The slot machine 10 has a square box-shaped housing 11. A square window-like display window 12 facing the player side is formed at the center and upper part of the casing 11. A symbol display window 13 through which the symbols 61 of the three rotary reels 40 can be seen is formed at the center of the display window 12 at the center. The bet switch 16 is a switch located below the rotary reel 40, and reduces the number of stored medals inserted and stored in the medal insertion slot 63 to replace the medal insertion. The settlement switch 17 is a switch located obliquely below the rotating reel, and pays out the stored inserted medal. The start switch 30 is a lever positioned obliquely below the rotary reel 40 and starts driving the reel unit 60 on condition that a game medal is inserted or the bet switch 16 is inserted. The stop switch 50 is for stopping the driving of the reel unit 60. The reel unit 60 is composed of three rotating reels 40. Each rotary reel 40 includes a rotary drum made of synthetic resin and a tape-like reel tape 42 attached around the rotary drum. A plurality of (for example, 21) symbols 61 are displayed on the outer peripheral surface of the reel tape 42. Reference numeral 62 denotes a liquid crystal display unit for performing various effects.

  Inside the slot machine 10, a control device for controlling the overall operation of the slot machine 10 is incorporated as will be described later. The control device is configured around a CPU and includes a ROM, a RAM, an I / O, and the like. Then, the CPU (processing unit) is operated by reading the program stored in the ROM (storage unit) in response to the player's operation. Specifically, the CPU operates the start switch 30 and the stop switch 50. Based on this, the rotation and stop of the rotary reel 40 are controlled, and the display of lamps, speakers, and the like are controlled. Temporary data necessary for the operation of the CPU is RAM (storage unit: RAM is generally a volatile memory, and data is lost in principle when the power is turned off. A backup power source such as a battery may be prepared. In this case, data is not lost even if the power is cut off). The CPU performs a predetermined operation in accordance with a program recorded in the ROM, records temporary data necessary for processing in the RAM, and reads out and refers to the recorded data as necessary.

  The start switch 30 is a lever that is positioned obliquely below the rotary reel 40 as described above. The start switch 30 can be obtained on the condition that a game medal is inserted or the bet switch 16 is inserted or according to a winning determination. "Replay)" is to start driving the reel unit 60 on condition that a predetermined time has elapsed since the previous game.

  The stop switch 50 is for stopping the driving of the reel unit 60 as described above. Specifically, the stop switch 50 includes three switches corresponding to each rotary reel 40, and one stop switch 50 is disposed below each rotary reel 40. The operation of the stop switch 50 corresponding to the rotating reel 40 is set to stop the rotation of the corresponding rotating reel 40.

  When the start switch 30 is operated on the condition that the medal is inserted or the bet switch 16 is inserted, or on the condition that a predetermined time elapses from the previous game at the time of the “replay”, the reel unit 60 is driven, and the three The rotary reel 40 starts to rotate. Thereafter, when one of the stop switches 50 is operated, the rotation of the corresponding rotary reel 40 is stopped. When all three stop switches 50 are operated, the rotation of the three rotary reels 40 is stopped. At this time, if a predetermined symbol 61 on the effective pay line of the display window 13 stops, it is determined that the winning is made, and a predetermined number of medals are paid out through a hopper unit (not shown). In addition, you may credit instead of paying out medals.

  FIG. 2 is a block diagram showing an electrical schematic structure of the slot machine 10. In this figure, the display about the power supply system is omitted. The slot machine 10 includes a main substrate 1 (first processing unit) and a sub-substrate 2 (second processing unit) that receives a command from the main substrate 1 and operates as a main processing device. At least the main substrate 1 is accommodated inside the case so that it cannot be contacted from the outside, and a sealing process is performed so that traces remain when the substrates are removed.

In the setting change mode, a change request for internal settings such as a winning probability is received from the setting switch / reset switch 84, and the internal setting is changed. The setting change unit 1a is realized by software or hardware (the same applies to the following functions). The setting key according to the embodiment of the present invention is not a mere key, but at least includes a storage unit (memory) therein, stores an ID code as identification information, and communicates the ID code with a gaming machine It is possible. Specifically, the setting key is an IC chip built-in key that contains an IC chip including a CPU and a memory, a non-contact IC card that can communicate with the outside wirelessly, and is inserted into a slot provided in advance to make electrical contact with the main body Such as a contact IC card.

  In addition to the IC card, a wireless IC tag (RF-ID) can be used. RFID (radio frequency identification) is a system in which a chip transmits an identification number using radio waves as power when a radio wave is applied to an IC chip with a reader, or a device therefor. An internal memory is provided, and a certain amount of data can be read and written. Used as a product tag for logistics and inventory management. Data is stored in a tag with a size of several centimeters, which is excellent for the environment, and communicates with the reader via radio waves. In recent years, a tag that does not have a battery and can be used semipermanently has appeared by a non-contact power transmission technique from the antenna side. The tag has various shapes such as a label type, a card type, a coin type, and a stick type, and is selected according to the application. The communication distance ranges from several millimeters to several meters, and these are also properly used depending on the application.

(3) Collation unit 1c: a circuit or function for collating the identification information stored in the setting key with the identification information stored in advance in the gaming machine (hereinafter, the identification information may be expressed as an ID code). (Identification information and ID code are the same). The collation unit 1c sends the collation result to the setting change unit 1a. The setting change unit 1a executes the setting change mode only when the two ID codes match in the verification process. If they do not match, the collation unit 1 c sends an error notification command to the sub-board 2.

(4) Storage unit 1d: a storage unit (memory) that stores identification information of gaming machines. The storage unit is configured to retain the stored content even when the power is turned off (for example, a battery backup is provided or a nonvolatile memory such as an EEPROM).

(5) ID code updating unit 1e: a circuit or function for updating the ID code after executing the setting change. The updated ID code is stored in both the setting key storage unit and the gaming machine storage unit 1d.

  The sub-board 2 is for receiving a command signal from the main board 1 and notifying the result of the internal lottery and performing various effects. The sub-board 2 includes a CPU that performs a control operation according to a preset program corresponding to the command signal, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results and the like.

  The sub board 2 includes an error notification section 2a (implemented by software or hardware) that receives an error notification command from the main board 1 and performs error notification.

  The sub-board 2 receives a command from the main board 1 and performs effects and other processing according to the command. The flow of commands is only one from the main board 1 to the sub board 2, and conversely, no command or the like is issued from the sub board 2 to the main board 1.

  In order to count the number of medals paid out from the random number generator 20, start switch 30, stop switch 50, reel drive 70, reel position detection circuit 71, hopper drive 80, hopper 81 and hopper 81 on the main board 1. Are connected to a medal detection unit 82, a setting key switch 83, and a setting switch / reset switch 84. Note that the random number generator 20 may be provided as hardware or software in the main board 1. A peripheral board (local board) such as a control board 200 of the liquid crystal display device 62, a speaker 201, and an LED board 202 is connected to the sub board 2. Hereinafter, these peripheral substrates / devices except for the start switch 30 and the stop switch 50 will be described.

  The random number generation unit 20 has a random number generation function for generating a pseudo random number by updating the numerical values in a certain range at high speed, and a sampling function for extracting an arbitrary random number from the generated random numbers in response to the player's operation. It is to be prepared. As a specific example, it is composed of a counter and a latch.

  The reel driving unit 70 is a circuit that drives a stepping motor (not shown) that rotationally drives the three reels 40. Each stepping motor is subjected to 1-2 phase excitation by the reel drive circuit 70 and rotates once when a drive signal having a predetermined number of pulses is supplied.

  The reel position detection circuit 71 is provided in the vicinity of the reel 40, receives an output pulse signal from a photo interrupter (not shown) for detecting the rotation position of the reel 40, detects the rotation position of each of the three reels 40, and detects it. A signal is output. A photo interrupter (not shown) detects a shielding plate provided on each reel 40 and generates a reset pulse every time each reel 40 rotates once. This reset pulse is given to the CPU of the main board 1 via the reel position detection circuit 71. In the RAM of the main board 1, a count value corresponding to the rotation position within one rotation range is stored for each reel 40, and when the CPU receives the reset pulse, the count value formed in the RAM is stored. Clear to “0”. By this clearing process, the deviation generated between the movement display of each symbol and the rotation of each stepping motor is eliminated every rotation.

  The hopper driving unit 80 is a circuit that drives a motor of a hopper 81 that stores medals and pays out the number of medals corresponding to the designated winning.

  The medal detection unit 82 is for counting the number of medals paid out from the hopper 81. The CPU of the main board 1 stops driving by the hopper driving unit 80 when the actually paid out medal count value received from the medal detection unit 82 reaches the predetermined payout number data corresponding to the winning. Finish paying out. A predetermined number of medals are paid out to the player by the hopper driving circuit 80 and the medal detection unit 82 based on a winning obtained as a result of the game.

  The setting key switch 83 and the setting switch / reset switch 84 are provided on a panel of a power supply unit (not shown). The setting switch / reset switch 84 serves both as a setting switch for selecting an internal setting value (setting value) and a reset switch for canceling an error.

The liquid crystal control board 200 is a circuit for driving the liquid crystal display unit 62.
The speaker 201 is for generating sound such as voice and sound effects.
The LED substrate 202 is a circuit for driving a display lamp and a back lamp (not shown).

  The liquid crystal display device 62 controlled by the liquid crystal control substrate 200 and the LED substrate 202 including the speaker 201 and the display lamp constitute an effect display device. This effect display device is for notifying a player of a prize or the like, or for teaching a user a specific small role during a certain game with some action during a so-called assist time (AT).

  The ROM of the main board 1 stores game processing procedures executed in the slot machine 10 as a sequence program, and stores a winning probability table, a symbol table, a winning symbol combination table, and the like. Has been. The winning probability table is divided so as to divide the random number extracted by the random number generation unit 20 into each winning mode, and the random number extracted from a certain range of numerical values generated by the random number generating unit 20 is assigned to each winning mode. The data to be partitioned into is stored. That is, the winning probability table has an area divided for each winning mode corresponding to the entire area of random numbers taken by the random number generator 20. For example, a range of 0 to a certain number is divided into a plurality, one division (area) is excluded, and the other division (area) is set as winning 1, winning 2,. The extracted random number data is collated with each of the winning determination area data divided for each winning mode in all areas corresponding to the random number generated from the random number generator 20, and the winning prize to which the extracted random number data belongs. The winning corresponding to the aspect is determined. For example, it is determined to which category (region) of the winning probability table the extracted random number value belongs, and if the category is, for example, a category of winning 1, it is determined as “winning 1”. Similarly, if the extracted random number value belongs to an out-of-range category (region) in the winning determination table 5, it is determined as “out”. For example, when the evaluation of the lottery process is out of place, it is set so that the predetermined symbols are not aligned (so-called kicking), and when winning, the predetermined symbols are aligned on the condition that the stop switch is pressed at a predetermined timing. (So-called pull-in). And if predetermined symbols are prepared, medals corresponding to winning symbols are paid out. Various winnings are generated under the probability according to the data setting of the winning probability table, and the symbol stop control is performed. For example, the operating hours of the day are not influenced by the skill of the player. The total medal payment rate is maintained almost constant.

  FIG. 3 is an internal setting process flowchart in the gaming machine according to the first embodiment of the present invention. Hereinafter, the operation of the gaming machine will be described based on this figure. In order to change the internal setting for selecting the winning probability table, the following procedure is required.

S1: The setting key is set and the setting key switch 83 is turned on. The setting key switch 83 is provided on a panel of a power supply unit (provided inside the door) (not shown). Normally off.

S2: A power switch (not shown) is turned on. As a result, power is supplied to the gaming machine. Since the setting key switch 83 is on, the CPU of the main board 1 reads this and executes the processes after S3. When the setting key switch 83 is off, S10: normal game processing is executed immediately.

S3: Perform ID code verification processing. The ID code stored in the setting key is collated with the ID code stored in the storage unit 1d.

S4: When the result of the collation in S3 matches, it is determined that the operation is performed with a regular setting key, and the setting change process after S5 is executed. If the result of the collation in S3 is inconsistent, it is determined as an illegal act and S11: error notification is performed. The processes of S3 and S4 will be described in more detail later.

S5: Select the internal setting. The internal setting can be set, for example, in 1 to 6 stages. When the setting switch / reset switch 84 is operated, the displayed set value changes.

S6: Press down the start switch 30.
S7: The set value is determined by the operation of S6, and the set value is stored in the main board 1.

S8: Update the ID code. This process will be described in more detail later.

S9: The setting key switch 83 is turned off. Then, the set value display on the display (not shown) disappears.

S10: The gaming machine is set to a normal gaming state. Thereafter, the game can be accepted.

S11: Error notification. The error notification is performed by emitting or blinking all or a part of the lamps, LEDs, and liquid crystal display device 62 that can be controlled by the sub-board 2, or by lighting or displaying a specific pattern, or blowing a speaker. Alternatively, it is performed by arbitrarily combining the notification modes. Instead of or in addition to this, an error signal may be output to the outside. This error signal is received by the hall computer, for example, and an error is displayed on the hall monitoring device.

  According to the gaming machine according to the first embodiment of the invention, in the operation of changing the setting of the gaming machine, the ID code of the setting key is collated with the ID code of the gaming machine, so the setting key storing the correct ID code is used. Unless it is changed, the setting cannot be changed. Even when the wiring of the setting key switch 83 is short-circuited, the setting change mode is not entered, so that unauthorized setting changes can be prevented. Moreover, since the ID code is updated every time the setting is changed, it is difficult to know the current ID code. Therefore, even if a setting key is prepared, the setting cannot be changed illegally by itself. According to the first embodiment of the present invention, an illegal setting change act can be effectively prevented.

  FIG. 4 is an explanatory diagram of the ID collating process according to the first embodiment of the invention. FIG. 5 is a detailed flowchart of the ID collation processing in S3 and S4. FIG. 6 is a detailed flowchart of the ID update process in S8.

The ID collation process and the ID update process will be described in detail with reference to FIGS.
As shown in FIG. 4, the setting key 100 includes a processing unit (CPU) 100a, a communication unit 100b, and a storage unit 100c. The communication unit 100b communicates with the communication unit 1b of the gaming machine 10. The storage unit 100c stores an ID code.

  First, the ID verification process will be described with reference to FIG.

S20: A predetermined signal is transmitted to the setting key 100. This signal is a signal for activating an IC built in the setting key 100 to perform a predetermined operation. The IC of the setting key 100 is designed to respond when a specific signal is received.

  If the setting key 100 is set in the setting key switch 83, the setting key 100 receives the above signal from the communication unit 1b of S30: gaming machine, and in response, reads out the S31: ID code. Send ID code.

S21: Determine whether there is a response. If there is no response, the setting key 100 is not set, or the setting key switch 83 is short-circuited, or a false key that does not include the communication unit 100b is inserted. S10: The normal game process is executed without changing. Note that error processing may be performed when it is determined to be a fraudulent action to notify the error and not accept the normal game.

S22: If there is a response, a signal (ID code) is received from the setting key 100.

S23: The ID code is read from the storage unit 1d.

S24: The ID code received in S22 is collated with the ID code read in S23. If these ID codes match, the collation is OK, so the setting change process after S5 in FIG. 3 is executed. If they do not match, the collation is NG, so S11 in FIG. 3: error notification is performed.

  Next, the ID update process will be described with reference to FIG.

S40: After the setting change process, a random number is acquired from the random number generator 20. For example, a random number is acquired when the start switch 30 is pressed. The random number generator 20 can also be used as a lottery processing circuit, but may be provided separately. Further, time data may be used instead of random numbers.

S41: The acquired random number value is overwritten and stored in the storage unit 1d of the gaming machine 10 as an ID code. Thereby, the ID code of the gaming machine is updated. Instead of using the random number value acquired as the ID code as it is, the random value may be converted by a predetermined algorithm, and the converted value may be stored as the ID code.

S42: A new ID code and an ID code update command are transmitted to the setting key 100. In response to this (S50), the setting key 100 overwrites and stores a new ID code in the storage unit 100c (S51). As a result, the ID code of the setting key 100 is updated.

  Through the processes of S40 to S42, S50, and S51, the ID codes of both the gaming machine and the setting key are updated. At the next setting change, if the setting key 100 is used, the collation process can be passed and the setting can be changed. However, if another setting key is used, the setting cannot be changed because the ID codes do not match. The ID code of the embodiment of the present invention is a so-called disposable key, and its safety is high.

  The above processing is based on the premise that the ID code of the setting code matches the ID code of the gaming machine. In order to change the setting, an initial setting is required to make the two coincide at the first use. The initial setting will be briefly described below.

(1) It is conceivable to write the same ID code on both the setting key and the gaming machine using a dedicated device at the time of factory shipment or hall installation for initial setting. If an IC card writing device for a setting key is used, an ID code can be written on the setting key, and an ID code can also be written in the storage unit 1d of the gaming machine 10 using a dedicated device. In this case, the ID code can be changed for each gaming machine and for each hall, which is preferable in terms of safety.

(2) An ID code for initial setting may be written in advance on both the setting key and the gaming machine. For example, “0000” is set as an ID code for initial setting, and this value is written in advance in both the setting key and the gaming machine. When the setting key is set for the first time after the hall is set, the ID code always matches, so the setting can be changed. After that, since the random number value acquired from the random number circuit becomes the ID code, the ID code is different for each gaming machine and each setting key. In the ID update process, when an ID code for initial setting is acquired, it is desirable to discard the ID code and acquire another ID code.

(3) A special code dedicated to initial setting is written in advance in the storage unit 1d of the gaming machine, and in this state, the gaming machine makes a verification OK with respect to the ID code of an arbitrary setting key (or when it is a special code) (The collating step may be skipped). For example, “FFFF” is a special code, and when this code is stored in the storage unit 1d of the gaming machine, the setting change is accepted regardless of the ID code of the setting key. An arbitrary setting key is accepted only at the beginning, but only a specific setting key is accepted thereafter. It is desirable to disable special codes after initialization. For example, once “FFFF” is received, a flag is set, and when the flag is set, “FFFF” is not accepted (the flag is not reset even in the initialization process of the gaming machine). This process eliminates the need to initialize the setting key ID code. Existing setting keys held on the hall side can also be used for newly installed gaming machines. In the ID update process, when the special ID code is acquired, it is necessary to discard it and acquire another ID code.

Embodiment 2 of the Invention
In the first embodiment of the present invention, there is one ID code stored in the setting key 100. In this case, it is necessary to prepare as many setting keys 100 as the number of gaming machines. FIG. 7 is an explanatory diagram of ID collation processing according to the second embodiment of the invention. As shown in FIG. 7, if a plurality of ID codes for each gaming machine are stored in the setting key 100, a plurality of gaming machines can be managed with one setting key 100. Specifically, the ID code is stored in association with the gaming machine specific code given to each gaming machine. The game machine specific code is written in advance at the time of factory shipment, for example.

  FIG. 8 is a detailed flowchart of ID collation processing according to the second embodiment of the invention. FIG. 6 is a detailed flowchart of the ID update process according to the second embodiment.

  In the verification process of FIG. 8, communication with the setting key is performed (S20 '), and if communication is possible (YES in S21'), a gaming machine specific code is transmitted to the setting key 100 (S21a). The gaming machine unique code is received (S30 '), the ID code corresponding to the gaming machine unique code is read (S30a), and the read ID code is transmitted (S31'). The gaming machine receives the ID code from the setting key 100 (S22). The following processing is the same as in the case of FIG. If communication with the setting key is not possible (NO in S21 '), a normal game is played (S10).

  In the update process of FIG. 9, the game machine unique code is transmitted together with the new ID code (S42 ′), and the new ID code is overwritten on the address of the game machine unique code with the setting key (S50 ′, S50a, S51 ′). Thus, the ID code of the setting key 100 is updated.

Embodiment 3 of the Invention
In the first and second embodiments of the present invention, an ID code is used as identification information. In the third embodiment of the present invention, a security code composed of the history of operation switches can be used as the ID code as identification information. The ID code according to the third embodiment of the invention is an arbitrary code registered by the hall manager using various operation switches such as the start switch 30 and the stop switch 50 of the gaming machine. The code is made up of the operation switches of the gaming machine that are pressed and their order. For example, as shown in FIG. 13, STOP1 → STOP2 → START_LEVER + STOP2 is the ID code. An unauthorized setting change request can be rejected based on the ID code.

  FIG. 10 is a block diagram showing an electrical schematic structure of the gaming machine 10 according to the third embodiment of the invention. 10, the same parts as those in FIG. 2 are denoted by the same reference numerals. The gaming machine 10 of FIG. 10 does not have the ID code storage unit 1d of FIG. 2, but includes an operation procedure monitoring unit 1f for generating an ID code instead.

  FIG. 11 shows a flowchart of the collation process according to the third embodiment of the invention. The process of FIG. 11 is executed when the power is turned on with the setting key set. The setting cannot be changed unless the processing of FIG. 11 is performed.

S20: A predetermined signal is transmitted to the setting key 100. This signal is a signal for activating an IC built in the setting key 100 to perform a predetermined operation. The IC of the setting key 100 is designed to respond when a specific signal is received.

  If the setting key 100 is set in the setting key switch 83, the setting key 100 receives the above signal from the communication unit 1b of the gaming machine S30, and in response to this, S31 '': related to the switch operation sequence The ID code is read and the read ID code is transmitted.

S21: Determine whether there is a response. If there is no response, it is considered that the setting key 100 is not set, or the setting key switch 83 is short-circuited. Therefore, the setting is not changed, and S10: normal game processing is executed. Note that error processing may be performed when it is determined to be a fraudulent action to notify the error and not accept the normal game.

S24: When the switch operation order is received from the setting key, this is temporarily stored.

S25: The switch operation order is monitored. Specifically, it is monitored which switch is pressed. One switch may be pressed, or a plurality of switches may be pressed simultaneously.

S26: It is monitored whether the stack switch is pressed. The stack switch is, for example, the bet switch 16.

S27: When the stack switch is pressed, the switch operation sequence is stacked on the RAM of the main board as an operation code. This will be specifically described with reference to FIG. When the first stop switch 30 is first pressed and then the bet switch 16 is pressed, the data A of the first stop switch 30 is stacked in the memory M (FIG. 13A). Next, when the third stop switch is pressed and then the bet switch 16 is pressed, the data B of the third stop switch is stacked in the memory M (FIG. 13B). Next, when the start switch 30 and the second stop switch are pressed, and then the bet switch 16 is pressed, data C indicating that the start switch 30 and the second stop switch are pressed simultaneously is stacked in the memory (FIG. 13). (C)). Data about which switch is operated in what order by A to C is obtained.

S28: It is monitored whether the registration switch is pressed. The registration switch is, for example, the start switch 30. When the start switch 30 is pressed alone, it functions as a registration switch. However, as described above, when it is pressed simultaneously with other switches, it is treated as data and stacked. The same applies to the bet switch 16.

S29: An operation code (for example, FIG. 13D) stacked in the RAM of the main board is acquired as an ID code.

S4: The ID code stored in S24 is collated with the ID code acquired in S29. If these ID codes match, the collation is OK, so the setting change process after S5 in FIG. 3 is executed. If they do not match, the collation is NG, so S11 in FIG. 3: error notification is performed.

  FIG. 12 shows a flowchart of the ID update process of the third embodiment of the invention.

S43: The switch operation order is monitored. Specifically, it is monitored which switch is pressed. One switch may be pressed, or a plurality of switches may be pressed simultaneously.

S44: It is monitored whether the stack switch is pressed. The stack switch is, for example, the bet switch 16.

S45: When the stack switch is pressed, the switch operation sequence is stacked on the RAM of the main board as an operation code. The details have already been explained.

S46: It is monitored whether the registration switch is pressed. The registration switch is, for example, the start switch 30. When the start switch 30 is pressed alone, it functions as a registration switch. However, as described above, when it is pressed simultaneously with other switches, it is treated as data and stacked. The same applies to the bet switch 16.

S47: When the registration switch is pressed, the operation code stacked in the RAM of the main board is stored in the RAM as an ID code. As shown in FIG. 13D, data of A, B, and C are stored as ID codes.

S48: The stored ID code is read, and a new ID code and an ID code update command are transmitted to the setting key 100. In response to this (S50), the setting key 100 overwrites and stores a new ID code in the storage unit 100c. As a result, the ID code of the setting key 100 is updated.

  As described above, according to the third embodiment of the present invention, when an operation of a pre-registered procedure is requested when performing a setting change and an operation that does not match a pre-registered ID code is performed, An error can be notified, and an illegal act related to a setting change can be prevented. Note that when the pre-registered procedure is not performed within a certain period of time, it may be timed out so that setting changes are not accepted.

  The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
