Description

  The present invention relates to a gaming machine equipped with a circuit board case for closing an area in which an electronic circuit board on which electronic components are assembled is accommodated.

  An electronic circuit board (for example, a main control board) mounted on a gaming machine is basically attached to a circuit adapter or the like on the back of the gaming board while being accommodated in a circuit board case.

  In particular, the main control board is an important board that governs the progress of the game, and the main control board also performs a lottery or the like that results in giving a lot of prize balls to the player. Hereinafter, a main control board will be described as an example of a representative electronic circuit board.

  The main control board is placed on a base plate that constitutes a part of the circuit board case, and a box-type upper lid is attached and sealed so as to surround the periphery of the base board. As a result, the main control board is accommodated by the base plate and the upper lid.

  A seal seal is stuck between the base plate and the upper lid so as to straddle them. This seal seal is no different from the well-known seal seal in that the trace remains when it is peeled off, and after the base plate and the upper lid are sealed once, The trace of opening can be left (refer patent document 1).

  Patent Document 2 proposes a circuit box in which an RFID function is added to a seal sticker. For example, an IC tag composed of an antenna and an IC chip is a typical example. When an external radio wave is received, power is generated by electromagnetic induction and information stored in the IC chip is output.

  The information stored in the IC chip of the IC tag provided on the seal sticker is collated with the identification code information of the main control board accommodated in the circuit board case. For example, only the main control board is peeled off after the seal sticker is peeled off. When exchanged, it is possible to recognize unauthorized exchange by comparing information stored in the IC chip with identification code information set on the main control board.

  Furthermore, when the seal seal is cut with a blade or the like, the antenna is cut. In this case, too, an error (eg, no response) is generated in a collation program that is regularly executed, so that it is recognized that the fraud has occurred. can do.

  However, in Patent Document 1 and Patent Document 2, for example, the circuit board case is removed from the circuit adapter on the back of the gaming machine, peeled off with a special solvent without breaking the seal, and some electronic components on the main control board are replaced. However, it is not necessary to launch a verification program to read the information stored in the IC chip with a reader for visual inspection of each game machine for the tricks such as reattaching the peeled seal. Must not. In some cases, it is not possible to quickly and easily find out that there has been a fraud in such an appearance inspection or collation program. In particular, Patent Document 2 is not general in terms of reader versatility and degree of spread, and the facilities are complicated, so that it may be difficult to obtain an understanding of the acceptance system from the store side.

  In view of the above facts, an object of the present invention is to obtain a gaming machine capable of quickly and easily confirming whether or not the circuit board case has been detached from the gaming machine.

The present invention provides a housing for housing an electronic circuit board, holding means for detachably holding the casing on a specific gantry, and conduction when the casing is mounted on the specific gantry by the holding means. A pair of terminals to be turned off, and the pair of terminals are made non-conductive in accordance with the detachment operation of the casing from the specific mount, and the non-conductive is maintained even when the specific mount of the casing is remounted. A displacement structure that is displaced in such a manner, and monitoring means for monitoring a conduction state between the pair of terminals at a specific time,
have.

  According to the present invention, when the housing is first mounted and held on a specific mount by the holding means, the pair of terminals are electrically connected.

  On the other hand, when the case is detached from the specific gantry, even if the pair of terminals become non-conductive with the detachment operation and the displacement structure is displaced and the case is mounted on the specific gantry again. The pair of terminals are not in a conductive state, and a non-conductive state is maintained.

  For this reason, the electrical connection state between the pair of terminals differs between the first time and the second and subsequent times when the housing is mounted on a specific frame.

  The monitoring means monitors the conduction state between the pair of terminals at a specific time.

  By this monitoring, it can be confirmed that the housing once attached has been detached once or more. That is, for example, even if the housing is detached due to fraud and is reattached so that it is difficult to understand visually, the determination can be made based on the monitoring result of the monitoring means.

  In the present invention, the pair of terminals are brought into a conductive state in accordance with an initial mounting operation of the casing to the specific mount by the holding means.

  As a result of the first mounting operation of the casing to the specific mount by the holding means, a pair of terminals are brought into a conductive state, so that no special process is added for fraud detection. Man-hours can be reduced.

  The present invention is further characterized by further comprising a notifying means for notifying at least the gaming machine unit of the monitoring result by the monitoring means.

  By notifying the monitoring result of the monitoring means by the notification means, it is possible to recognize the history of attachment / detachment of the housing by the gaming machine alone without adding a special device or utilizing the network.

  In the present invention, the specific time is a time when power is supplied to the electronic circuit board.

  For example, when the gaming machine arrives at the store from factory shipment, monitoring by the monitoring means is performed when the power is turned on, so that the attachment / detachment state of the housing being transported can be recognized. Further, by performing monitoring by the monitoring means when the power is turned on at the opening of each day, it is possible to recognize the attachment / detachment state of the casing after the previous closing.

  Furthermore, in the present invention, the pair of terminals are connected to signal lines wired to the electronic circuit board, respectively, and prior to execution of the gaming machine activation program that is activated when the power is turned on in the electronic circuit board, Monitoring by the monitoring means is executed, and when the conduction state between the pair of terminals is abnormal as a result of monitoring by the monitoring means, the starting of the gaming machine starting program is stopped.

  If the conduction state between the pair of terminals is abnormal as a result of monitoring by the monitoring means, for example, the progress of the game on the electric circuit board different from the regular electronic circuit board is stopped by stopping the activation of the gaming machine activation program Can be prevented in advance.

  Further, in the present invention, the displacement structure can be moved to a fixedly arranged first conductor, a conduction position that is electrically connected to the first conductor, and a non-conduction position that is not electrically connected to the first conductor. A second conductor, and the second conductor is engaged with the pair of terminals in the first attachment of the housing to the specific mount in the conduction position, and after the engagement. It is characterized by moving to the non-conducting position in accordance with the separation operation.

  The first conductor and the second conductor are in a conductive state before the housing is mounted. As a result, the pair of terminals are engaged with the second conductor, so that the pair of terminals It becomes a conductive state.

  On the other hand, since the second conductor moves to the non-conduction position in accordance with the detachment operation of the housing, the first conductor and the second conductor are non-conductive even when the next housing is mounted. As a result, it is possible to realize that the pair of terminals do not become conductive.

  Furthermore, in the present invention, the movement of the second conductor from the conduction position to the non-conduction position is accompanied by a visible breakage of the displacement structure.

  In the second conductor, since the movement from the conducting position to the non-conducting position is accompanied by a visible breakage of the displacement structure, it is possible to confirm the detachment of the housing from the appearance.

  According to the present invention, there is a case for housing the electronic circuit board, holding means for detachably holding the case on a specific gantry, and an operation for mounting the case on the specific gantry by the holding means. A displacement structure that conducts between a pair of terminals, displaces so that the pair of terminals become non-conducting in accordance with the detachment operation of the casing from the specific mount, and is maintained even when reattached And monitoring means for constantly monitoring the conduction state between the pair of terminals, and storage means for storing at least non-conduction in the monitoring means.

  According to the present invention, when the holding means is mounted to hold the casing on a specific gantry, the pair of terminals are brought into conduction with the mounting operation.

  On the other hand, when the case is detached from the specific gantry, even if the pair of terminals become non-conductive with the detachment operation and the displacement structure is displaced and the case is mounted on the specific gantry again. The pair of terminals are not in a conductive state, and a non-conductive state is maintained.

  For this reason, the electrical connection state between the pair of terminals differs between the first time and the second and subsequent times when the housing is mounted on a specific frame.

  The monitoring means always monitors the conduction state between the pair of terminals.

  By this monitoring, it can be confirmed that the housing once attached has been detached once or more. That is, for example, even if the housing is detached due to fraud and is reattached so that it is difficult to understand visually, the determination can be made based on the monitoring result of the monitoring means.

  Further, the monitoring means always monitors the mounting state of the housing and the specific mount, and the storage means stores at least non-conductivity under the monitoring of the monitoring means. It is possible to grasp the number of times the casing is detached, the date and time, and the like.

  As described above, the present invention has an excellent effect that it is possible to quickly and easily confirm whether or not the circuit board case has been detached from the gaming machine.

That is, although not shown, an IC chip and an antenna (IC tag) are provided on the back side of the seal seal 260. Whether or not the RFID function is provided can be selected depending on the specification, and may simply be the seal sticker 260.

(Circuit board case attachment / detachment structure)
Hereinafter, taking the circuit board case 210 that houses the electronic circuit board 218 constituting the main controller 150 as an example, a structure for attaching to and detaching from the circuit adapter 220 (see FIG. 3) will be described. In addition, about the other circuit board cases 212, 214, and 216, when the same attachment / detachment structure as the circuit board case 210 is taken, another fixing means may be taken.

  As shown in FIG. 5, the hook portion 229 is formed from the front end of the holding portion 227 provided on the side wall on one short side of the closing cover portion 222 of the circuit board case 210 as described above.

  On the other hand, the circuit adapter 220 has an engaging portion 233 corresponding to the hook portion 229.

  As shown in FIG. 5, the engaging portion 233 has a box shape and is formed with a groove portion 233A into which the hook portion 229 is fitted. Here, when the circuit board case 210 is attached to the circuit adapter 220, first, the circuit board case 210 is abutted against the attachment surface of the circuit adapter 220 in a substantially parallel state (see FIG. 7A). The hook portion 229 is inserted into the groove portion 233A of the engaging portion 233 by sliding movement (generally, sliding the circuit board case 210). In this state, the circuit board case 210 is positioned at a specific position of the circuit adapter 220 (first step).

  Here, the base portion 224 of the circuit board case 210 is provided with an anchor pin 235 on the side opposite to the short side where the protruding piece 231 is formed (the side where the trace portion 232 is provided).

  With the circuit board case 210 positioned on the circuit adapter 220, the axis of the anchor pin 235 is aligned with the axis of the hole 220A (see FIGS. 7B and 7C) provided in the circuit adapter 220. It has become so. For this reason, by pressing the anchor pin 235 in the positioning state, the anchor pin 235 is inserted and fixed in the hole 220A (second step).

  Through the operations of the first step and the second step, the circuit board case 210 is completely attached to the circuit adapter 220.

(Circuit board case attachment / detachment history monitoring structure and monitoring control)
As shown in FIG. 7, an attachment / detachment monitoring device 300 for monitoring each other's attachment / detachment history is provided between the circuit adapter 220 and the circuit board case 210 according to the present embodiment.

  The attachment / detachment monitoring apparatus 300 includes a terminal unit 302 on the circuit adapter 220 side and a conduction unit 304 on the circuit board case 210 side.

  The terminal unit 302 includes a rectangular case attached to the engaging portion 233 of the circuit adapter 220, and a pair of metal (conductor) terminal portions 306 protrude from the side surface of the case. The protruding direction of the terminal portion 306 is the attaching / detaching operation direction of the circuit board case 210. For this reason, the front-end | tip part of a pair of terminal part 306 faces the circuit board case 210 of mounting | wearing operation | movement. Moreover, the front-end | tip part of a pair of terminal part 306 is bent in the shape of a hook in the mutually opposite direction.

  In the case of the terminal unit 302, the pair of terminal portions 306 are electrically connected to a harness portion 308 attached to the upper surface portion of the case so as not to contact each other. The harness unit 308 includes a connector unit 310 at the tip. In the present embodiment, the harness portion 308 has a structure in which a plurality of wirings are arranged in a flat manner. However, a necessary number of lead wires (in this embodiment, at least two lead wires) are simply used. You may comprise.

  On the other hand, the conduction unit 304 includes a rectangular case attached to the closing cover portion 222 (flat portion 222A), and an opening 312 that receives the pair of terminal portions 306 on a side surface facing the pair of terminal portions 306. Is formed.

  As shown in FIGS. 8 and 9, a pair of metal (conductor) round bars 314 are arranged in the case of the conduction unit 304 with the vertical direction as the axis. The pair of round bars 314 can move in the direction perpendicular to the axis along the guide portion 316 in the case.

  The guide portion 316 communicates with the opening 312 and both ends of the pair of round bars 314 in the moving direction are refracted to the side opposite to the side where the opening 312 is provided (hereinafter referred to as “back side”). It is formed to do.

  In addition, a metal (conductor) plate 318 (corresponding to the top and bottom of the opening 312) is attached to the back side of the guide portion 316, and is always in contact with a pair of round bars 314 that move the guide portion 316. It is supposed to be. In other words, as long as the pair of round bars 314 are accommodated in the guide portion 316, it can be said that the plates 318 are always in a conductive state.

  Here, when the circuit board case 210 is attached to the circuit adapter 220, the distal ends of the pair of terminal portions 306 of the terminal unit 302 enter the opening 312 of the conduction unit 304 as the attachment operation moves. It will be.

  Further, as the mounting operation proceeds, the pair of terminal portions 306 interfere with the pair of round bars 314, respectively, and depend on the bending of the pair of terminal portions 306 and the movement of the pair of round bars 314 at the guide portion 316. Thus, a so-called engaged state is obtained. In this engaged state, the pair of terminal portions 306 are in a conductive state via the pair of round bars 314 and the plate 318. That is, no special work is required for electrical connection, and the work of attaching the circuit board case 210 to the circuit adapter 220 also serves as a process for detecting fraud, so that the number of work steps can be reduced.

  In the engaged state, that is, after the circuit board case 210 is attached to the circuit adapter 220 (see FIG. 7B), the wiring connector portion 230 exposing the connector portion 310 from the closing cover portion 222. (See FIG. 7C).

  As a result, a signal related to the conduction state of the pair of terminal portions 306 of the terminal unit 302 can be processed in the electronic circuit board 218 attached in the circuit board case 210.

  In the present embodiment, when power is turned on in main control unit 150 (see FIG. 4), first, an attachment / detachment history determination program for determining the conduction state of the pair of terminal units 306 is activated. It has become.

  Further, in the conduction unit 304, after the pair of terminal portions 306 are engaged with the pair of round bars 314, the engagement state cannot be released unless the case of the conduction unit 304 is damaged. It has become.

  Here, in the case of the conduction unit 304, the peripheral portion of the opening 312 is structurally lower in strength than the other portions. As a means for reducing the strength, for example, a structure in which the peripheral portion of the opening 312 is thinner in thickness than the other portions, or the peripheral portion or a part thereof is notched is conceivable.

  In other words, when trying to remove the circuit board case 210 once attached to the circuit adapter 220, the pair of terminal portions 306 move with the pair of engaged round bars 314, and the low-strength opening portion As a result, the pair of round bars 314 are dropped from the case, and the structure of the attachment / detachment history can be visually confirmed.

  Even if the circuit board case 210 is attached to the circuit adapter 220 again, the pair of terminal portions 306 will not be in a conductive state. As described above, the conduction state of the pair of terminal portions 306 can be confirmed by control determination by starting the attachment / detachment history determination program. In the control judgment, for example, when there is an abnormality, it is preferable to activate a warning system that displays the fact on the LCD display unit 106 or notifies the hall computer.

  FIG. 10 is an example of a circuit for determining the conduction state of the pair of terminal units 306 in the main control unit 150. A signal line 320 connected to one terminal unit 306 via the harness unit 308 is determined in advance. A voltage + V (for example, a voltage of a control signal level such as 3.3 V or 5.0 V) is applied.

  The signal line 322 connected to the other terminal portion 306 via the harness portion 308 is branched, one is grounded via the resistor 324, and the other is connected to the input end of the CPU 326.

  As a result, when the pair of terminal portions 306 are conductive, a high level signal (H signal) is input to the CPU 326, and when the pair of terminal portions 306 is non-conductive, the CPU 326 has a low level. Signal (L signal) is input. By monitoring the state of this signal, the conduction state of the pair of terminal portions 306 can be recognized.

  The operation of this embodiment will be described below.

  In a game using the pachinko machine 10, when a player operates the grip unit 26, the ball is shot upward by the launching device 165 one by one (for example, the firing interval is about 100 balls / 60 seconds). The launched game ball PB is driven into the game area of the game board 18 along the outer rail 102 and falls in the game area while changing the direction by hitting a game nail or a windmill. Then, the game ball PB reaching the lower end of the game area without winning a prize is collected into the pachinko machine 10 from the out port 124.

  When the game ball PB wins a special symbol start winning opening (A) or a special symbol start winning opening (B) provided in the game area, or passes through the passing gate 118, a process based on each game specification (for example, , Lottery, etc.), and an image display effect on the LCD display unit 106, a sound effect using the speaker 60, and the like are executed. In addition, when winning a prize in the general winning opening 120, a predetermined prize ball (payout) is executed.

(Outline of game specifications)
First, the game control centered on the lottery process in the main control unit 150 will be described.

  When the game ball PB wins the special symbol start winning opening (A) 130 or the special symbol start winning opening (B) 134, it is determined whether or not it is an effective start winning prize. The effective start winning is a game where the reserved balls are not full (for example, four for one start opening) and the special symbol starting winning opening (A) 130 or the special symbol starting winning opening (B) 134 is played. Saying that the ball PB has won a prize, and thereby, a lottery right is obtained. In the invalid starting prize, the right to draw is not given, but a predetermined number (about 3 to 5) of prize balls may be paid out.

  If the starting prize is an effective starting prize, a random number is acquired, a pre-stored winning value is read, and both are compared to determine whether the lottery is winning or not.

  If the current gaming state is in the design variation effect, add 1 (+1) to the number of holdings to hold the right to draw, and when the design variation effect is no longer in the normal gaming state The lottery process is executed by subtracting the number of holdings by one.

  Based on the winning / losing of the lottery, a symbol variation effect time is set, and a command including the lottery result and the symbol variation effect time is sent to the effect control unit 152.

  The effect control unit 152 notifies the result of the lottery using the set effect time (execution of the symbol variation effect).

  After this notification, if the result of the lottery is a win, a special gaming state (a jackpot process) is executed. In the special game state, the attacker 112 that is always closed under the normal game state is opened and closed by a predetermined number of rounds (R) (for example, about 2R to 16R).

  The maximum opening time of the attacker 112 is about 30 seconds, and when the attacker 112 wins a predetermined number (for example, 4 to 10) of game balls during the opening time, the attacker 112 After the closing time, move to the next round (open). Thus, the player can receive a lot of prize balls in the same time in the normal gaming state.

  This game specification is a game specification accompanied by a special drawing lottery. However, in this embodiment, the game specification is not limited, and so-called blades in which the game state changes only by the flow of game balls. It may be a game specification of a type or a game specification using a combination of a plurality of game specifications.

(Illegal avoidance structure of circuit board case)
Here, the progress of the game is executed by control by cooperation of a plurality of electronic circuit boards 218 provided on the back surface of the game board 18. A plurality of electronic circuit boards 218 and the like are housed and protected in circuit board cases 210, 212, 214, and 216, respectively. In particular, the electronic circuit board 218 corresponding to the main control unit 150 is an important board that performs the winning determination process and the lottery process and manages the progress of the game based on the winning determination result and the lottery result. A mechanism for leaving a trace in the open / close state of 210 is provided. In the present embodiment, an example in which the circuit board case 210 is provided has been described.

  More specifically, a screwdriver is assigned to the cylindrical portion 234, the cover member 236 is pierced, and the internal screw is screwed into the small hole of the circular groove portion 238, thereby opening the next opening. Sometimes, it is necessary to cut off either or both of the cylindrical portion 234 and the circular groove portion 238 that have been screwed together with a nipper, a cutter, or the like as a tool, so that traces can be reliably left.

  Further, when the RFID function is added to the seal sticker 260, if the seal sticker 260 is genuine, it matches the identification information stored in the IC tag reader, and if it is illegal, it is stored in the IC tag reader. The identification code information does not match (or the identification code information cannot be acquired by the IC tag reader).

  Further, since the seal seal 260 is accommodated in the cavity 240 and cannot be touched from the outside, for example, the seal seal 260 is peeled off with a solvent, the internal electronic components are replaced, tampered, etc. Unauthorized actions such as re-pasting are impossible.

(History of attaching / detaching the circuit board case 210)
In the above, it is illegal avoidance when separating the closing cover portion 222 and the base portion 224 of the circuit board case 210.

  On the other hand, the circuit board case 210 itself may be removed from the circuit adapter 220. The purpose of detachment may be fraudulent behavior, dropout due to improper mounting, etc.

  When the purpose is fraud, when another circuit board case is attached to the circuit adapter 220 instead of the circuit board case 210 that was originally attached, the trace portion 232 and the seal seal 260 are detachable in appearance. There are no traces left. Therefore, in the present embodiment, the attachment / detachment monitoring device 300 is provided to monitor attachment / detachment of the circuit board case 210 visually and in a controlled manner.

(Visual attachment / detachment monitoring)
A procedure for mounting the circuit board case 210 to the circuit adapter 220 and a procedure for removing the circuit board case 210 from the circuit adapter 220 will be described with reference to FIGS.

  First, when the circuit board case 210 is attached to the circuit adapter 220, as shown in FIG. 7A, the circuit board case 210 is abutted against the attachment surface of the circuit adapter 220 in a substantially parallel state and slides in this state. It is moved (generally, the circuit board case 210 is slid) (see FIG. 7A). As a result, the hook portion 229 is inserted into the groove portion 233A of the engaging portion 233 (the first step described above), and the tip of the anchor pin 235 is inserted into the hole 220A by pressing the anchor pin 235 in the positioning state. And fixed (the second step described above).

  The circuit board case 210 may be mounted on the circuit adapter 220 by providing a protruding piece on the long side and sliding it.

  On the other hand, as shown in FIG. 9A, a pair of terminal portions 306 projecting from the terminal unit 302 of the attachment / detachment monitoring apparatus 300 are connected to the conduction unit 304 by the operations of the first step and the second step. Depending on the bending of the pair of terminal portions 306 themselves and the movement of the pair of round bars 314 in the guide portion 316, the pair of terminal portions 306 and the pair of round bars 314 are so-called engagements. It becomes a joint state.

  The engagement state is not necessarily accompanied by the operations of the first step and the second step, and the manual operation of another step is performed during the initial mounting operation of the circuit board case 210 and the circuit adapter 220. It is good also as an engagement state.

  When the circuit board case 210 is attached to the circuit adapter 220, the connector part 310 provided on the terminal unit 302 via the harness part 308 is connected to one of the wiring connector parts 230 (FIG. 7B to FIG. 7 (C) state).

  Next, when detaching the circuit board case 210 from the circuit adapter 220, the connectors including the connector portion 310, all the connectors connected to the wiring connector portion 230 are removed, and the anchor pin 235 is released in the second step described above. Then, contrary to the operation in the first step, the hook portion 229 is detached from the engaging portion 233 (detachment operation).

  At this time, as shown in FIG. 9B, since the pair of terminal portions 306 are engaged with the pair of round bars 314, the pair of round bars 314 move with respect to the detachment operation. As a result, the peripheral portion of the opening 312 provided in the case of the conduction unit 304 is pierced and discharged (see FIG. 7D).

  As a result, in the mounting operation between the circuit board case 210 and the circuit adapter 220 other than the first, the pair of round bars 314 are not dropped and do not exist, and thus the pair of terminal portions 306 are not in a conductive state.

(Attachment / detachment monitoring control by attachment / detachment history judgment program)
FIG. 8 and FIG. 9 show a state change specialized for the attachment / detachment monitoring apparatus 300 in the attachment / detachment operation of the circuit board case 210 with respect to the circuit adapter 220.

  FIG. 9A shows a state change when the circuit board case 210 is attached to the circuit adapter 220 (change from FIG. 8A to FIG. 8B).

  FIG. 9B shows a state change when the circuit board case 210 is detached from the circuit adapter 220 (change from FIG. 8B to FIG. 8C).

  As shown in FIGS. 8B and 9A, when the circuit board case 210 is attached to the circuit adapter 220, the pair of terminal portions 306 are in a conductive state via the pair of round bars 314 and the plate 318. It turns out that it becomes.

  On the other hand, as shown in FIGS. 8C and 9B, it can be seen that when the circuit board case 210 is detached from the circuit adapter 220, the pair of terminal portions 306 become non-conductive. In this embodiment mode, the conduction information of the pair of terminal portions 306 is determined using the circuit shown in FIG.

  FIG. 11 is a flowchart showing an attachment / detachment history determination control routine based on signals from the pair of terminal units 306, which is executed in the main control unit 150 based on the circuit shown in FIG.

  In addition, the time of power-on includes power-on at the time of factory shipment, power-on when installing in a hall, trial operation, power-on on hall business day, power-on by inspection during closing, power-on after power failure recovery, Conditions may be selected as necessary.

  As shown in FIG. 11, in step 350, first, a voltage (+ V) is applied to one terminal unit 306 of the attachment / detachment monitoring apparatus 300, and the process proceeds to step 352.

  In step 352, a signal from the attachment / detachment monitoring apparatus 300, that is, a signal indicating the conduction state of the pair of terminal portions 306 is captured.

  In this case, since a voltage is applied to one terminal portion 306, a high level signal (H signal) is sent to the CPU 326 when the pair of terminal portions 306 are in a conductive state via the pair of round bars 314 and the plate 318. ) Is entered.

  When the round bar 314 is removed (discharged) and the pair of terminal portions 306 are in a non-conducting state, a low level signal (L signal) is input to the CPU 326.

  In the next step 354, the level of the signal input to the CPU 326 is determined.

  If it is determined in step 354 that the H signal has been input to the CPU 326, it is determined that the circuit board case 210 once attached to the circuit adapter 220 has not been detached, and the process proceeds to step 356.

  In step 356, it is recognized that the normal state of the circuit board case 210 is maintained, the execution of the gaming machine activation program is instructed, and this routine ends.

  If it is determined in step 354 that the L signal has been input to the CPU 326, it is determined that the circuit board case 210 once attached to the circuit adapter 220 has been detached, and the process proceeds to step 358.

  In step 358, it is recognized that the circuit board case 210 is in an abnormal state (a state where there is a history of removal from the circuit adapter 220), and a warning notification is executed. As a form of warning notification, there are a control for displaying a warning on the LCD display unit 106, a control for turning on and blinking the light emitting element 137, a control for outputting a sound from the speaker 60, and the like. Is done. The warning notification may be combined with a plurality of forms. In any case, the history of attachment / detachment of the circuit board case 210 from the circuit adapter 220 can be recognized by a pachinko machine alone without adding a special device or using a network.

  In the next step 360, the hall computer is notified, and then the routine proceeds to step 362 to instruct to stop the execution of the game machine starting program, and this routine ends.

  As described above, in the attachment / detachment monitoring apparatus 300 according to the present embodiment, when the circuit board case 210 itself is removed from the circuit adapter 220, the pair of terminal portions 306 are brought into a conductive state along with the removal operation. Since the pair of round bars 314 are ejected from the guide portion 316 and the conductive state of the pair of terminal portions 306 is released, the removal trace of the circuit board case 210 can be visually confirmed, and when the power is turned on Also, determination can be made in terms of control.

  When the pair of terminal portions 306 of the terminal unit 302 of the attachment / detachment monitoring device 300 are engaged with the pair of round bars 314 with the conduction unit 304, the circuit board case 210 is attached to the circuit adapter 220 along with the mounting operation. However, the engaging operation does not necessarily have to be accompanied by the mounting operation of the circuit board substrate case 210 to the circuit adapter 220, either before or after the circuit machine board case 210 is mounted to the circuit adapter 220. In addition, the engaging operation may be performed in a separate process. In other words, when the circuit board case 210 is removed from the circuit adapter 220, the engagement between the pair of terminal portions 306 and the pair of round bars 314 may be released along with the removal operation.

  The attachment / detachment monitoring apparatus 300 according to the present embodiment is particularly effective in the transport process from factory shipment to store. That is, in the conveyance process, the monitoring system of the pachinko machine 10 has not been established, and the attachment / detachment history of the circuit board case 210 could not be recognized. However, in the present embodiment, the pachinko machine 10 arrives at the store, and when the power is turned on after the pachinko machine 10 is installed on the island, it is possible to confirm the history of attachment / detachment of the circuit board case 210 during the transportation process.

  In addition, even when the power is turned on before opening each day in the store, it is possible to automatically check the attachment / detachment state of the circuit board case 210 since the previous store closing, so that complicated check work (one by one) The operation of visually checking the pachinko machine, particularly the control circuit system, or using a specific inspection instrument) can be omitted.

  In the present embodiment, the determination control of the attachment / detachment monitoring device 300 is performed when the power of the pachinko machine 10 is turned on. However, as shown in FIG. 12, the attachment / detachment monitoring device 301 independent of the main control unit 150 is provided. It may be. The attachment / detachment monitoring device 301 includes a monitoring circuit 301A and a memory 301B, and may include a power supply 301C (for example, a battery). As a result, even if the circuit board case 210 once removed is attached to the circuit adapter 220 again, even if a device for short-circuiting the pair of terminal portions 306 is taken, the history of attachment / detachment in the process from factory shipment to hall installation Can be stored in the memory 301B, and the stored information can be taken out from the output terminal 301D.
