The main IC 300x is, for example, a V5 chip, and incorporates a main CPU 300a, a main ROM 300b, and a main RAM 300c (not shown in FIG. 4, see FIG. 8). Based on the input signals from each detection switch and timer, the main CPU 300a reads the program stored in the main ROM 300b and performs arithmetic processing, directly controls each device and display, or produces the result of arithmetic processing. Send commands to other boards accordingly. Further, the main RAM 300c functions as a data work area during arithmetic processing of the main CPU 300a.

A RAM clear button 305 is provided at the lower left portion of the main control board 300. The RAM clear button 305 is arranged so as to be exposed to the outside from the main control board case 311 so that the RAM clear button 305 can be operated with the main control board case 311 sealed. When the RAM clear button 305 is pressed, the RAM clear detection switch 305s (see FIG. 8) detects the pressing operation of the RAM clear button 305, and a RAM clear signal is output. The RAM clear signal is used, for example, to determine whether or not the main CPU 300a initializes the main RAM 300c when the power is turned on.

(Setting key operation)
The main control board 300 is provided with a setting key insertion port 306 in addition to the RAM clear button 305. The setting key insertion port 306 is an insertion port (keyhole) for inserting a dedicated key (setting key) used for changing a setting value or referring to the setting value, which will be described later. The game machine 100 according to the present embodiment is configured so that the set value can be set in 6 stages of 1 to 6 by pressing the RAM clear button 305 together with the operation of the setting key. As will be described in detail later, in the game machine 100, the game progresses according to the set value being set, and the degree of advantage differs depending on the set value.

The setting key insertion port 306 is composed of a cylinder lock having a cylinder. Further, the cylinder of the setting key insertion port 306 is provided in a state of penetrating the main control board case 311 (a state in which the periphery of the cylinder is surrounded by the main control board case 311). Therefore, it is possible to insert the setting key into the setting key insertion port 306 and perform the rotation operation while the main control board 300 is sealed in the main control board case 311.

(Internal configuration of control means)
FIG. 8 is a block diagram showing an internal configuration of a control means for controlling the progress of the game.

The main control board 300 controls the basic operation of the game. The main control board 300 includes a main CPU 300a, a main ROM 300b, and a main RAM 300c. Based on the input signals from each detection switch and timer, the main CPU 300a reads the program stored in the main ROM 300b and performs arithmetic processing, directly controls each device and display, or produces the result of arithmetic processing. Send commands to other boards accordingly. Further, the main CPU 300a uses the main RAM 300c and the internal register (not shown) of the main CPU 300a as a data work area at the time of arithmetic processing.

Here, among the memory areas used by the main CPU 300a as the work area, application examples of the memory areas (F000H to F3FFH) allocated to the main RAM 300c will be described with reference to FIG.
As shown in FIG. 9, in the game machine 100 according to the present embodiment, the regions of the addresses F000H to F1FFH are divided into four regions from the first region to the fourth region according to the type of data to be stored. The first area is an area for storing information related to the set value (setting value related information) and information related to the gaming state (game state related information). The second area is an area for storing checksum-related information and backup-related information used for error detection related to power recovery in the CPU initialization process described later. The third area is an area for storing error-related information and the first normal game state information. The fourth area is an area for storing the second normal game information and an area used as a stack area.
The areas of addresses F000H to F1FFH including the first to fourth areas are referred to as used areas. The used area is a memory area for storing information (data) essential for the progress of the game machine, and the used capacity is limited by the game rules.

In the main RAM 300c, the areas of addresses F300H to F3FFH are areas used for storing information that is not essential for the progress of the game, and are referred to as unused areas. In this example, information related to display control of the performance display 300d (performance display-related information) is stored in the non-use area. In addition, information related to output control of the test signal may be stored in the non-use area. The test signal is the current internal state of the game machine 100 (for example, special game management phase, normal game management phase, launch position designation state, execution status of major game, game state (high probability, low probability, time reduction, non-time reduction). ) Etc.) is a signal output to notify the outside of the main control board 300 immediately (in real time).

Further, as shown in FIG. 9, the area between the used area and the unused area (the area of the addresses F200H to F2FF) is an unused area that is not used for storing data.
As described above, in the game machine 100, the main RAM 300c is composed of a used area, an unused area, and an unused area. In this example, the main RAM 300c is assigned an address value for each byte area. Therefore, an area corresponding to 256 bytes is allocated as an unused area. As the unused area, an area of at least 16 bytes or more may be allocated.

Returning to FIG. 8, the games executed by the game machine 100 of the present embodiment mainly include a special game started by entering the game ball into the first start port 120 or the second start port 122, and the gate 124. It is roughly divided into a normal game that is started when a game ball passes through. The main ROM 300b of the main control board 300 stores various programs for advancing special games and normal games, as well as data and tables required for various games.

The main control board 300 has a general winning opening detection switch 118s for detecting that a game ball has entered the general winning opening 118, and a first starting port for detecting that a game ball has entered the first starting port 120. Detection switch 120s, 2nd start port detection switch 122s for detecting that a game ball has entered the 2nd start port 122, gate detection switch 124s for detecting that a game ball has passed through the gate 124, 1st grand prize opening The first large winning opening detection switch 126s that detects that a game ball has entered 126, and the second large winning opening detection switch 128s that detects that a game ball has entered the second large winning opening 128 are connected. A detection signal is input to the main control board 300 from each of these detection switches.

Further, the main control board 300 opens and closes the ordinary electric accessory solenoid 122c that operates the movable piece 122b of the second starting port 122, the opening / closing door solenoid 126c1 that operates the opening / closing door 126a, and the first special winning opening 126. The first special winning opening solenoid 126c2 that operates the opening / closing door 126b and the second special winning opening solenoid 128c that operates the opening / closing door 128b that opens / closes the second special winning opening 128 are connected by the main control board 300. , The opening / closing control of the second starting port 122, the first special winning opening 126, and the second large winning opening 128 is performed.

Further, the main control board 300 includes a first special symbol display 160, a second special symbol display 162, a first special symbol hold indicator 164, a second special symbol hold indicator 166, a normal symbol display 168, and a normal symbol display. The symbol hold indicator 170 and the right-handed notification indicator 172 are connected to each other, and the display control of each of these indicators is performed by the main control board 300.

Further, the front frame opening switch 141s, the out detection switch 143s, and the inner frame opening switch 145s are connected to the game machine 100. Hereinafter, the inner frame opening switch 145s and the front frame opening switch 141s may be collectively referred to as an opening / closing frame member opening switch. The opening / closing frame member release switch is a switch that detects that the opening / closing frame member such as the inner frame 104 or the front frame 106 is open in the game machine 100.

When the front frame opening switch 141s detects that the front frame 106 is open, the front frame opening switch 141s outputs an opening detection signal (on signal) to the main control board 300. Further, when the inner frame opening switch 145s detects that the inner frame 104 is open to the outer frame 102, the inner frame opening switch 145s outputs an opening detection signal (on signal) to the main control board 300.

Further, although not shown in FIG. 8, in addition to the opening / closing frame member release switch, the game machine 100 detects that there is an abnormality in each configuration of the game machine 100 or a possibility of fraud for each configuration. An abnormality detection switch may be provided. For example, the game machine 100 may be provided with a radio wave detection switch for detecting radio waves, a magnetic detection switch for detecting magnetism, and the like as abnormality detection switches.

When the out detection switch 143s detects that the game ball launched into the game area 116 has passed through the game ball discharge path (not shown) that is passed when the game ball is discharged to the outside of the game machine 100, the out detection switch 143s is connected to the main control board 300. Outputs an out-ball detection signal (on signal).
A game ball that has entered any of the general winning openings 118, the first starting opening 120, the second starting opening 122, the first major winning opening 126, and the second major winning opening 128, and any of the winning openings. The game ball that has entered the discharge port 130 without passing through the above-mentioned game machine ball discharge path. That is, all the game balls that are aggregated and discharged to the outside after being launched into the game area 116 are detected by the out detection switch 143s in the game ball discharge path.

Further, on the back surface of the game board 108, a setting key switch 180s and a RAM clear detection switch 305s are provided. The setting key switch 180s is configured to be accessible by the setting key described above. When the setting key switch 180s detects the rotation operation of the setting key inserted into the setting key insertion port 306, the setting key rotation detection signal (ON signal) indicating the state of the rotation operation (rotation state) is sent to the main control board 300. Output.
Further, the RAM clear detection switch 305s is configured to be accessible by pressing the RAM clear button 305. When the RAM clear detection switch 305s detects the pressing (pressing operation) of the RAM clear button 305, the RAM clear detection switch 305s outputs a pressing detection signal (on signal) to the main control board 300.

The game machine 100 according to the present embodiment can change the set value by using the setting key and the RAM clear button 305 that can access the setting key switch 180s.
Here, the procedure for changing the set value will be described.

(Procedure for changing setting values)
The procedure of the operation for changing the setting value among the operations related to the setting value will be described.
First, when the power of the game machine 100 is not turned on (power is turned off), the operator who changes the setting opens the inner frame 104 with respect to the outer frame 102 by using a dedicated key. As a result, the components such as the main control board 300 arranged on the back surface of the game machine 100 become visible.
On the back surface of the game machine 100, a setting key insertion port 306 for inserting the setting key and a RAM clear button 305 are provided as described above (see FIG. 4). The operator inserts the setting key into the setting key insertion port 306, and rotates (changes) the setting key in one direction (for example, clockwise direction). Further, the operator presses the RAM clear button 305.

Next, the operator turns on the game machine 100 while rotating the setting key and pressing the RAM clear button 305.
When the power is turned on, the inner frame opening switch 145s detects that the inner frame 104 is open to the outer frame 102, and the opening detection signal (on signal) is input to the main control board 300. Further, the setting key switch 180s detects that the setting key is rotated clockwise when the power is turned on, and the setting key rotation detection signal (on signal) is input to the main control board 300. Further, the RAM clear detection switch 305s detects that the RAM clear button is pressed by turning on the power, and the press detection signal (ON signal) is input to the main control board 300. The game machine 100 can change (switch) the set value based on the on signal being input to the main control board 300 by the inner frame opening switch 145s, the setting key switch 180s, and the RAM clear detection switch 305s. The setting is changed).

The operator changes the set value to any one of a plurality of stages (for example, 6 stages) by pressing the RAM clear button 305 any number of times in the setting change state and accessing the RAM clear detection switch 305s. be able to. At this time, the set value is displayed in the display area 361-364 of the performance display 300d, for example.

When the operator changes the set value to an arbitrary value, the operator rotates the setting key rotated clockwise at the time of the change operation counterclockwise to return it to the original position (return operation). By the return operation, the setting key switch 180s detects that the setting key has returned to the original position, and a signal (off signal) indicating the detection is input from the setting key switch 180s to the main control board 300. The main control board 300 confirms the change of the set value based on the input of the off signal. The setting key switch 180s periodically outputs a setting key rotation detection signal (on signal) to the main control board 300 based on the detection of the rotation operation, and outputs the on signal until the return operation is detected. If it continues and the return operation is detected, the output of the setting key rotation detection signal (ON signal) to the main control board 300 may be stopped. In this case, the main control board 300 may confirm the change of the set value based on the fact that the input of the on signal is stopped.

When the change of the set value is confirmed and the operator pulls out the setting key from the setting key insertion port 306, the set value displayed on the performance display 300d is erased and the display of the set value ends (the set value is changed). It will be hidden). Finally, the operator closes the inner frame 104 of the game machine 100 and locks it with a dedicated key. This completes the setting change work. When the setting change work is completed, the normal game is started.

Although the details will be described later, when the set value is changed, the main CPU 300a of the main control board 300 sets the changed set value to a predetermined area of the main RAM 300c (for example, the first area among the used areas to be backed up). ). As a result, the set value being set during the game can be referred to.

In this way, the game machine 100 detects the change operation of the setting key in the setting key switch 180s (setting key ON) when the power is turned on, and the inner frame 104 is released in the inner frame opening switch 145s (inner frame open state). ) Is detected and the RAM clear button 305 is pressed by the RAM clear detection switch 305s (RAM clear pressed state), the setting change state (setting change mode) is set.
In the setting change state, the indicators 160 to 172 that display information such as special games and ordinary games are not displayed, and normal games such as launching a game ball and a prize ball of a game ball cannot be performed. In the setting change state, each display 160 to 172 may maintain the off state, or maintain a dedicated (specific) lighting pattern in the setting change state and display different from the normal display. It may be an embodiment.

(Setting confirmation status)
Although the change of the set value has been described above, in the game machine 100, as an operation related to the set value, it is possible to perform an operation of confirming the set value currently being set without changing the set value.
Specifically, when the power is turned on to the game machine 100 without pressing the RAM clear button 305 in the state where the setting key is changed (rotated in the clockwise direction) in the above setting changing procedure, the setting is currently being performed. It becomes a state where the setting value of can be confirmed (setting confirmation state).

That is, when the power is turned on, the game machine 100 detects the operation of changing the setting key with the setting key switch 180s (setting key ON), and releases the inner frame 104 images with the inner frame opening switch 145s (inner frame open state). When it is detected and the RAM clear button 305 is not detected by the RAM clear detection switch 305s (RAM clear not pressed state), the setting confirmation state (setting confirmation mode) is set.
Similar to the setting change state, in the setting confirmation state, each display 160 to 172 is not displayed, and a normal game such as a game ball launch or a game ball prize ball cannot be performed. In the setting confirmation state, each display 160 to 172 may maintain the off state, or maintain a dedicated (specific) lighting pattern during the setting confirmation and display mode different from the normal display. It may be. Further, in the setting confirmation state, each display 160 to 172 may maintain a dedicated (specific) lighting pattern and have a display mode different from the setting change state.

As shown in FIG. 8, the payout control board 310 and the sub control board 330 are connected to the main control board 300.

The payout control board 310 controls for launching the game ball and controls for paying out the prize ball. The payout control board 310 also includes a CPU, a ROM, and a RAM, and is connected to the main control board 300 so as to be able to communicate in both directions. A game information output terminal board 312 is connected to the payout control board 310, and various information on the game progress output from the main control board 300 is transmitted via the payout control board 310 and the game information output terminal board 312. It will be output to the hall computer of the amusement store.

Further, the payout control board 310 is connected to a payout motor 314 for paying out the game balls stored in the storage unit to the player as prize balls. The payout control board 310 controls the payout motor 314 based on the payout number designation command transmitted from the main control board 300 to control the player to pay out a predetermined prize ball. At this time, the payout of the game balls is detected by the payout detection switch 315s, the number of game balls paid out is detected by the payout ball counting switch 316s, and it is grasped whether the prize balls to be paid out are paid out to the player. It has become. Each time the prize ball is actually paid out by driving the payout motor 314, the detection signal from the payout detection switch 315s and the count signal from the payout ball counting switch 316s are input to the payout control board 310.

Further, the payout control board 310 is connected to a dish full tank detection switch 318s that detects the full tank state of the lower dish 134. The plate full tank detection switch 318s is provided in a passage that guides the game ball to be paid out as a prize ball to the lower plate 134, and each time the game ball passes through the passage, a game ball detection signal is input to the payout control board 310. It is supposed to be done.

Then, when a predetermined amount or more of game balls are stored in the lower plate 134 and become full, the game balls stay in the passage toward the lower plate 134, and the plate full tank detection switch 318s is directed toward the payout control board 310. , The game ball detection signal is continuously input. When the game ball detection signal is continuously input for a predetermined time, the payout control board 310 determines that the lower plate 134 is in a full tank state, and transmits a plate full tank command to the main control board 300. On the other hand, if the continuous input of the game ball detection signal is interrupted after the dish full tank command is transmitted, it is determined that the dish full tank state has been released, and the dish full tank release command is transmitted to the main control board 300.

Further, the launch control board 320 is bidirectionally connected to the payout control board 310 so as to be communicable. When the launch control board 320 receives the launch control data from the payout control board 310, the launch control board 320 permits the launch. The launch control board 320 is provided on the operation handle 112, and is connected to a touch sensor 112s that detects that the player touches the operation handle 112 and an operation volume 112a that detects the operation angle of the operation handle 112. .. Then, when a signal is input from the touch sensor 112s and the operation volume 112a, the launch control board 320 is controlled to energize the launch solenoid 112c provided in the game ball launcher to launch the game ball.

The sub-control board 330 mainly controls each effect such as during a game or during standby. The sub control board 330 includes a sub CPU 330a, a sub ROM 330b, a sub RAM 330c, an image control unit 340, a voice control unit 350, a lighting control unit 360, and a movable body control unit 370. The sub CPU 330a, the image control unit 340, the voice control unit 350, the lighting control unit 360, and the movable body control unit 370 may each be configured by individual circuits. Further, at least two or more of the sub CPU 330a, the image control unit 340, the voice control unit 350, the lighting control unit 360, and the movable body control unit 370 are configured by one circuit (for example, one package or one chip). It may be configured as a functional block of the circuit.

The sub-control board 330 is unidirectionally connected to the main control board 300 from the main control board 300 to the sub-control board 330 so as to be communicable. Based on the command transmitted from the main control board 300, the input signal from the timer, etc., the sub CPU 330a reads the program stored in the sub ROM 330b, performs arithmetic processing, and displays a command for executing the effect as an image. It transmits to at least one of the control unit 340, the voice control unit 350, the lighting control unit 360, and the movable body control unit 370. At this time, the sub RAM 330c functions as a data work area during the arithmetic processing of the sub CPU 330a.

The image control unit 340 performs image display control for displaying an image on the effect display unit 200a of the effect display device 200, and includes a CPU, a ROM, a RAM, and a VRAM. The ROM of the image control unit 340 stores a large amount of image data such as a design and a background displayed on the effect display unit 200a, and the CPU outputs the image data based on the command transmitted from the sub-control board 330. The image display of the effect display unit 200a is controlled by reading from the ROM to the VRAM.

The voice control unit 350 performs voice output control for outputting voice from the voice output device 206 based on a command transmitted from the sub-control board 330. Further, the lighting control unit 360 performs lighting control for lighting the effect lighting device 204 based on a command transmitted from the sub-control board 330. The movable body control unit 370 moves the effecting accessory device 202 or causes the pressing button 208a of the effect operating device 208 to pop out to the player side based on the command transmitted from the sub-control board 330. Control the operation. Further, the movable body control unit 370 is connected to the button operation detection switch 208s1 for detecting that the pressing button 208a has been pressed, or the lever operation detecting switch 208s2 for detecting that the effect lever 208b of the effect operation device 208 has been input-operated. When the operation detection signal is input, a predetermined command or control signal is transmitted to the sub-control board 330.

A power supply board (not shown) is connected to each board, and power is supplied from a commercial power source to each board via the power supply board. Further, the power supply board is provided with a backup power supply composed of a capacitor.

Next, the game in the game machine 100 of the present embodiment will be described together with various tables stored in the main ROM 300b.

As described above, in the game machine 100 of the present embodiment, two types of games, a special game and a normal game, proceed in parallel, and a low-probability game state is defined as a game state when both of these games are performed. Alternatively, the game proceeds in any of the gaming states in which any of the high-probability gaming states and the non-time-saving gaming state or the time-saving gaming state are combined.

The details of each game state will be described later, but in the low-probability game state, the probability of acquiring the right to execute the big role game in which the first big prize opening 126 and the second big prize opening 128 are opened is set low. It is a gaming state, and a high-probability gaming state is a gaming state in which the probability of acquiring the right to execute a major role game is set high.

Further, the non-time-saving game state is a game state in which the movable piece 122b is unlikely to be opened and the game ball is difficult to enter the second starting port 122, and the time-saving game state is compared to the non-time-saving game state. However, the movable piece 122b is likely to be in the open state, and the game ball is likely to enter the second starting port 122. The initial state of the gaming machine 100 is set to a low-probability gaming state and a non-time-saving gaming state, and this gaming state is referred to as a normal gaming state in the present embodiment.

When the player operates the operation handle 112 to launch the game ball into the game area 116 and the game ball flowing down the game area 116 enters the first start port 120 or the second start port 122, the player is allowed to play the game. A lottery for whether or not to give a profit (hereinafter referred to as a "major role lottery") is held. In this big role lottery, if a big hit is won, the first big winning opening 126 (or the second big winning opening 128) is opened and the game ball to the first big winning opening 126 (or the second big winning opening 128) A large role game that enables entry into a ball is executed, and the game state after the end of the large role game is set to any of the above game states. The major role lottery method will be described below.

Although detailed description will be omitted, when a game ball enters the first starting port 120 or the second starting port 122, various random numbers (big hit determination random numbers, winning symbols) used in the big win lottery will be triggered by this entry. Random numbers (random numbers, reach group determined random numbers, reach mode determined random numbers, fluctuation pattern random numbers) are acquired, and each of these random numbers is stored in the special figure reservation storage area of the main RAM 300c. In the following, various random numbers stored in the special figure hold storage area when the game ball enters the first start port 120 are collectively referred to as special 1 hold, and the game ball enters the second start port 122. The various random numbers stored in the special figure hold storage area are collectively called special 2 hold.

The special figure reservation storage area of the main RAM 300c includes a first special figure reservation storage area and a second special figure reservation storage area. The first special figure reserved storage area and the second special figure reserved storage area each have four storage units (first to fourth storage units). Then, when the game ball enters the first start port 120, the special 1 hold is stored in order from the first storage unit of the first special figure hold storage area, and when the game ball enters the second start port 122, the special 1 hold is stored. 2 Holds are stored in order from the first storage unit of the second special figure hold storage area.

For example, when a game ball enters the first starting port 120, if the hold is not stored in any of the first to fourth storage units of the first special figure hold storage area, the first storage unit is used. Special 1 Hold is stored. Further, for example, when a game ball enters the first starting port 120 in a state where the special 1 hold is stored in the first storage unit to the third storage unit, the special 1 hold is set to the fourth storage unit. Remember. Even when the game ball enters the second starting port 122, the special 2 hold is stored in the 1st to 4th storage units of the 2nd special figure hold storage area in the same manner as described above. Special 2 hold is stored in the storage unit with the smallest number (ordinal number).

However, the number of special 1 hold (X1) and the number of special 2 hold (X2) that can be stored in the first special figure hold storage area and the second special figure hold storage area are set to four, respectively. Therefore, for example, when a game ball enters the first starting port 120, if four special 1 holdings are already stored in the first special figure holding storage area, the first starting port 120 is entered. No new special 1 hold is memorized by entering the game ball. Similarly, when the game ball enters the second starting port 122, if four special 2 holdings are already stored in the second special figure holding storage area, the game to the second starting port 122 is played. No new special 2 hold is memorized by entering the ball.

As described above, in the game machine 100, a special game triggered by the entry of the game ball into the first start port 120 or the second start port 122 (see FIG. 3) and a game to the gate 124 (see FIG. 3). A normal game triggered by the passage of the ball progresses in parallel at the same time. The process related to the special game is executed stepwise and repeatedly. Similarly, in the game machine 100, the process related to the normal game triggered by the passage of the game ball to the gate 124 is executed stepwise and repeatedly.

In the game machine 100, the main CPU 300a provided on the main control board 300 performs each process related to the special game and each process related to the normal game in a predetermined cycle (this description is omitted) in the CPU initialization process (detailed description is omitted). In the embodiment, it is executed in the timer interrupt processing that interrupts by 4 milliseconds, hereinafter "milliseconds" is expressed as "ms"). The main CPU 300a transmits a command including information on the result of the process related to the special game and the process related to the normal game in the timer interrupt process to the sub-control board 330.

Next, a specific configuration of the movable cover 309 provided in the game machine 100 according to the present embodiment will be described with reference to FIGS. 4 to 7 and 10 to 12 with reference to FIGS. 13 and 14. FIG. 13 is a six-view view of the movable cover 309. The upper part of FIG. 13 shows a plan view of the movable cover 309, and the middle part of FIG. 13 shows a rear view, a left side view, a front view, and a right side view of the movable cover 309 from the left. The bottom view of the movable cover 309 is shown in the lower part of 13. FIG. 14 is a perspective view of the movable cover 309.

As shown in FIGS. 13 and 14, the movable cover 309 has a main body portion 391 arranged on the back side of the set value operation unit 301 (see FIG. 4) when the back cover 302 is attached to the game machine 100. are doing. The main body 391 has a thin plate shape. The main body portion 391 has a rectangular shape when viewed in the normal direction of the main body portion 391. The main body 391 is made of, for example, a transparent resin material (for example, polycarbonate). Therefore, even when the movable cover 309 is in the closed state, the set value operation unit 301 can be visually recognized through the main body unit 391.

As shown in the front view and the rear view in FIG. 13, the movable cover 309 has a shaft portion 392L formed at the upper left corner portion of the main body portion 391. The shaft portion 392L has an extending portion 392Lb extending from the left side wall of the main body portion 391 and a protruding portion 392La protruding from the extending portion 392Lb. The protruding portion 392La is formed so as to be substantially parallel to the long side of the main body portion 391 and projecting toward the left side. As shown in the left side view in FIG. 13, the protrusion 392La has a cylindrical shape slightly crushed in one diameter direction. The extending portion 392Lb is integrally formed of the same material (for example, polycarbonate) as the main body portion 391. The protruding portion 392La is integrally formed of the same material (for example, polycarbonate) as the extending portion 392Lb.

As shown in the front view and the rear view in FIG. 13, the movable cover 309 has a shaft portion 392R formed at the upper right corner portion of the main body portion 391. The shaft portion 392R has an extending portion 392Rb extending from the right side wall of the main body portion 391 and a protruding portion 392Ra protruding from the extending portion 392Rb. The protrusion 392Ra is formed so as to be substantially parallel to the long side of the main body 391 and to protrude toward the right side. As shown in the right side view in FIG. 13, the protrusion 392Ra has a cylindrical shape slightly crushed in one diameter direction. The extending portion 392Rb is integrally formed of the same material (for example, polycarbonate) as the main body portion 391. The protruding portion 392Ra is integrally formed of the same material (for example, polycarbonate) as the extending portion 392Rb.

The central axis of the protrusion 392Ra and the central axis of the protrusion 392La are arranged in a straight line. As a result, the movable cover 309 ensures a smooth rotational operation with respect to the back cover 302.

The protrusion 392La is formed to have a shorter width in the lateral direction and a longer width in the longitudinal direction than the width of the U-shaped opening formed in the bearing portion 322Lb (see FIG. 12) forming the shaft arrangement portion 322L. .. Further, the protrusion 392Ra is formed to have a shorter width in the lateral direction and a longer width in the longitudinal direction than the width of the U-shaped opening formed in the bearing portion 322Rb (see FIG. 12) forming the shaft arrangement portion 322R. ing. As shown in the left side view and the right side view in FIG. 13, the protrusions 392La and 392Ra are formed so that the longitudinal direction coincides with the thickness direction of the movable cover 309. Therefore, when the movable cover 309 is in the closed state, the protruding portions 392La and 392Ra have bearing portions 322Lb and 322Rb so that the lateral direction coincides with the width direction of the U-shaped opening formed in the bearing portions 322Lb and 322Rb. Placed in. On the other hand, when the movable cover 309 is in the open state, the protrusions 392La and 392Ra are arranged in the bearing portions 322Lb and 322Rb so that the longitudinal direction coincides with the width direction of the U-shaped opening formed in the bearing portions 322Lb and 322Rb. Will be done. The width of the protrusions 392La and 392Ra in the longitudinal direction is larger than the width of the U-shaped opening.

Therefore, the rotation range of the movable cover 309 is restricted, and the rotation angle at which the movable cover 309 can rotate is smaller than 90 °. As a result, when the movable cover 309 in the open state is released, the movable cover 309 is in a state of closing the opening 321 although it is not in the locked state (details will be described later). In this way, in the game machine 100, even if the operator forgets to lock the movable cover 309 after performing the operation related to the set value, the movable cover 309 is in the state of closing the opening 321. It is possible to prevent the portion 301 from being maintained in an exposed state.

As shown in FIGS. 13 and 14, the movable cover 309 has a wall-shaped portion 393 formed along an end facing the end of the main body 391 provided with the shaft portions 392L and 392R. .. When the movable cover 309 is closed, the wall-shaped portion 393 is provided in a predetermined area including the center of the end portion of the main body portion 391 provided with the shaft portions 392L and 392R. The wall-shaped portion 393 is provided at a position corresponding to the convex portion 323 (see FIG. 11) provided on the back cover 302. As shown in FIG. 14, the wall-shaped portion 393 has a thin plate shape protruding toward the front side of the movable cover 309. As shown in the left side view and the right side view in FIG. 13, the wall-shaped portion 393 has a bent portion 393a formed by bending the vicinity of the tip end. Although the details will be described later, when the movable cover 309 is closed, the tip end portion of the convex portion 323 provided on the back cover 302 is hooked on the bent portion 393a of the wall-shaped portion 393. As a result, the game machine 100 is configured to be in a locked state in which the movable cover 309 is maintained in the closed state.

As shown in FIGS. 13 and 14, the main body portion 391 has an overhanging portion 391a provided on both sides of the wall-shaped portion 393 and overhanging outward. The overhanging portion 391a is provided so that an operator or the like can hook a finger when the movable cover 309 is changed from the closed state to the open state. The overhanging portion 391a has a thin rectangular parallelepiped shape. The overhanging portion 391a is formed so as to extend in a direction substantially orthogonal to the projecting direction of the wall-shaped portion 393. When the movable cover 309 is closed, the two overhanging portions 391a are provided at positions corresponding to the two concave portions 324 (see FIG. 11) provided on the back cover 302. The concave portion 324 is formed to be recessed on the side opposite to the side on which the overhanging portion 391a is arranged. Therefore, a gap is formed between the overhanging portion 391a and the concave portion 324. As a result, the catching of the finger on the overhanging portion 391a is improved, so that the operator or the like can easily shift the movable cover 309 from the closed state to the open state.

Next, a method of attaching the movable cover 309 to the back cover 302 and a relative relationship between the back cover 302 and the movable cover 309 will be described with reference to FIGS. 10 to 13 with reference to FIGS. 15 and 16. FIG. 15 is a cross-sectional view of the back cover 302 to which the movable cover 309 is attached, cut along the line AA shown in FIG. 11 (b). FIG. 15 is a cross-sectional view of the back cover 302 to which the movable cover 309 is attached, which is cut along the line BB shown in FIG. 11 (b).

First, a method of attaching the movable cover 309 to the back cover 302 will be described with reference to FIG. The movable cover 309 is attached from the back side of the back cover 302. Further, in the movable cover 309, after the shaft portion 392L (or the shaft portion 392R) is arranged on the shaft arrangement portion 322L (or the shaft arrangement portion 322R), the shaft portion 392R (or the shaft portion 392L) is placed on the shaft arrangement portion 322R (or the shaft). It is pushed into the arrangement portion 322L) to arrange the protrusion 392Ra (or the protrusion 392La) on the bearing portion 322Rb (or the bearing portion 322Lb). As a result, the movable cover 309 is rotatably attached to the back cover 302.

More specifically, for example, first, the protrusion 392Ra of the shaft portion 392R is inserted from the left side between the inclined portion 322Ra and the bearing portion 322Rb of the shaft arrangement portion 322R. Next, from the back side of the back cover 302, the protrusion 392La of the shaft portion 392L is pressed against the inclined portion 322La of the shaft arrangement portion 322L. Then, the protrusion 392La receives a force from the inclined portion 322La in the direction in which the opening 321 is provided. As a result, in the shaft portion 392L, the protruding portion 392La slides the inclined portion 322La toward the opening portion 321 in a state where the extending portion 392Lb is flexed in the direction of the opening portion 321 and elastically deformed. When the protrusion 392La reaches the opening 321, the protrusion 392La does not receive a force from the inclined portion 322La. Therefore, the extending portion 392Lb returns from the elastically deformed state to the original state (linear state). As a result, the protrusion 392La is inserted into the space surrounded by the inclined portion 322La and the bearing portion 322Lb from the U-shaped opening formed in the bearing portion 322Lb, and the shaft portion 392L is arranged in the shaft arrangement portion 322L. In this way, the attachment of the movable cover 309 to the back cover 302 is completed. The shaft portions 392L and 392R are arranged in the shaft arrangement portions 322L and 322R unless the protrusion 392La (or the protrusion 392Ra) receives a force enough to disengage from the shaft arrangement portion 322L (or the shaft arrangement portion 322R). The state can be maintained.

As described above, in the game machine 100, since the shaft arrangement portions 322L and 322R have the inclined portions 322La and 322Ra, the movable cover 309 is backed by pushing the shaft portions 392L and 392R into the shaft arrangement portions 322L and 322R. It can be attached to the cover 302. On the other hand, in the game machine 100, in order to remove the movable cover 309 from the back cover 302, a force sufficient to disengage at least one of the protrusions 392La and 392Ra from the shaft arrangement portions 322L and 322R must be applied to the shaft portions 392L and 392R. It doesn't become. Therefore, the game machine 100 has a structure in which the movable cover 309 can be easily attached to the back cover 302, and the movable cover 309 is difficult to remove from the back cover 302 (the movable cover 309 is hard to come off from the back cover 302).

Next, the relative relationship between the back cover 302 and the movable cover 309 will be described with reference to FIG.
