  FIG. 5 is a functional block diagram showing an electrical configuration of the pachinko machine. In the functional block diagram shown in the figure, only the portions related to the present invention are shown, and other portions are omitted. The pachinko machine 2 includes a game control device 120. The game control device 120 includes a CPU 121, a ROM 122, and a RAM 123. The CPU 121 functions as the control unit 126 and the state determination unit 127 by executing the game control program 125 stored in the ROM 122. For example, when the control unit 126 wins a winning device provided in the game area 25, the control unit 126 executes payout of a gaming ball as a winning ball, or when the transition lottery is performed, the symbols on the symbol display device 32 can be changed. Display and stop display indicating the lottery result are executed. In addition, an effect start signal is output to the lamp control device (transmission stop means) 130 and the sound control device (transmission stop means) 131. In response to this, lighting / extinguishing of the main body side lighting 132 assembled to the main body member 3 and the lighting boards 11 and 12 provided on the upper door 4 are executed. In the sound control device 131, the production sound is reproduced on the speaker 133 provided on the main body member 3 and the speakers 13 and 14 provided on the upper door 4.

  The state determination unit 127 is provided to determine whether or not the first contact terminal 88 and the second contact terminal 89 are energized, that is, whether or not the key switch 85 is turned on. When the state determination unit 127 determines that the key switch 85 is turned on, the control unit 126 outputs a power supply stop signal to the lamp control device 130 and the sound control device 131. While the control unit 126 is in the on state after the output of the power supply stop signal, the lamp control device 130 and the sound control device 131 stop the power supply to the electrical boards 11 and 12 and the speakers 13 and 14, and Regulates the output of the production start signal. Note that not only the production start signal but also the output of the control signal when the production is being performed may be restricted. In the present embodiment, when the key switch 85 is turned on, both the power supply stop to the control device (lighting board) on the upper door 4 side and the output restriction of the production start signal are performed. However, it is also possible to only stop power supply to the control device (lighting board) on the upper door 4 side.

  Next, the operation of this embodiment will be described. In a state where the pachinko machine 2 is disposed in the island facility of the game hall, the main body member 3 of the pachinko machine 2 is held in a closed state with respect to the fixed frame 8 by the locking device 50. The upper door 4 is also held in a closed state with respect to the main body member 3 by the locking device 50. As shown in FIG. 6, in this state, since the unlock key 22 is not inserted into the key cylinder 20, the key switch 85 is in the OFF state. For example, when the maintenance of the game board or the replacement of the upper door 4 such as the adjustment of the obstacle nail disposed in the game area 25, the upper door 4 is rotated to the open state. A shop clerk or worker in the field rotates the unlocking key 22 in the direction A in FIG. 1 after inserting the unlocking key 22 into the key hole 21 of the key cylinder 20. For example, when the unlock key 22 is inserted into the key cylinder 20, the tip of the unlock key 22 comes into contact with the insertion portion 86 b of the pin 86 that has entered the cylinder portion 75. In this state, the unlock key 22 is not completely inserted into the key cylinder 20 and cannot be rotated. Therefore, it is necessary to further insert the unlock key 22 into the key cylinder 20.

  Further, when the unlocking key 22 is inserted into the key cylinder 20, the pin 86 abutted against the tip of the unlocking key 22 is pressed and moves in the H direction in FIG. 7 against the bias of the coil spring 87. When the pin 86 moves in the H direction in FIG. 7, the tip of the pressing portion 86 c comes into contact with the tip of the first contact terminal 88, and then the tip of the first contact terminal 88 faces the second contact terminal 89. Press. As a result, the distal end portion of the first contact terminal 88 is curved and contacts the second contact terminal 89. Energization is performed by contact between the first contact terminal 88 and the second contact terminal 89, that is, the key switch 85 is turned on.

  Since the state determination unit 127 determines whether or not the key switch 85 is turned on, the key switch 85 is turned on when the first contact terminal 88 and the second contact terminal 89 are brought into contact and energized. It is determined that it is in a state. In response to this determination, the control unit 126 outputs a power supply stop signal to the lamp control device 130 and the sound control device 131. Thereafter, the control unit 126 stops the power supply to the lighting boards 11 and 12 assembled to the upper door of the lamp control device 130, and stops the power supply to the speakers 13 and 14 and starts the production of the sound control device 131. Regulate signal output. Thereby, it is possible to prevent the upper door 4 from being opened during the electrical communication from the control unit 126 to the control device on the upper door 4 side, thereby causing a data communication failure.

  A store clerk or worker at the amusement hall inserts the unlock key 22 into the key cylinder 20 and then rotates it in the direction A in FIG. At this time, the engagement between the first locking claw 51 of the locking device 50 and the engaging portion 60 provided on the upper door 4, and the engagement provided on the first locking claw 52 of the locking device 50 and the upper door 4. The engagement with the joint portion 61 is released, and the upper door 4 can be rotated from the closed state to the open state. Thereby, the operator and worker of a game hall will rotate the upper door 4 to an open state. In the process of turning the upper door 4 to the open state, the fitting between the main body side connector 45 and the door side connector 46 is released. In addition, in the state where the locking of the main body member 3 and the upper door 4 by the locking device 50 is released, power supply and signal transmission are performed on the electric decoration boards 11 and 12 and the speakers 13 and 14 assembled to the upper door 4. Because it is not known, there will be no electric shock or data reading trouble. In addition, since it is not necessary to turn off the power switch of the pachinko machine 2 in advance when the upper door 4 is replaced, the amount of work during such replacement can be reduced.

  Further, when the replacement of the upper door 4 is completed, the upper door 4 is turned to the closed state. When the upper door is turned to the closed state, after the main body side connector 45 and the door side connector 46 are fitted, the upper door 4 and the main body member 3 are locked by the locking device 50. Then, the unlock key 22 is pulled out from the key cylinder 20. By pulling out the unlocking key 22 from the key cylinder 20, the pin 86 moves in the G direction in FIG. 4 or 6 by the bias of the coil spring 87, so that the contact between the first contact terminal 88 and the second contact terminal 89 is made. Is released. That is, the key switch 85 is turned off. At this time, since the state determination unit 127 determines that the key switch 85 is in the OFF state, the lamp control device 130 and the sound control device 131 start supplying power to the electrical boards 11 and 12 and the speakers 13 and 14. At the same time, the output restriction of the production start signal is canceled. Thereby, the lighting / extinguishing control of the LED 10 mounted on the electrical decoration boards 11 and 12 and the sound reproduction by the speakers 13 and 14 become possible. In this case, since power is supplied to the game control device 120 incorporated in the main body member 3, chattering (ON) that occurs when the power switch of the pachinko machine 2 is turned on after the replacement work is completed. However, it is possible to suppress the occurrence of the ON / OFF state or the influence thereof.

  In this embodiment, the power supply to the upper door is stopped by detecting that the unlocking key is inserted into the key cylinder by the key switch. However, the present invention is not limited to this. By detecting the rotation of the unlocking key inserted in the power supply, it is possible to stop the power supply to the upper door and to restrict the output of the signal. In the following, portions having the same functions as those of the present embodiment will be described with the same reference numerals as those of the present embodiment.

  As shown in FIGS. 8 to 10, the key switch (rotation detecting means) 140 includes a top member 141, a first contact terminal 142, second contact terminals 143 and 144, and a holding member 145 that holds these members. To do. The top member 141 includes a pair of arc-shaped connecting pieces 141b and 141c that protrude in the front direction from one surface of a base portion 141a having a substantially disk shape. The connecting pieces 141b and 141c are inserted into a pair of arc-shaped insertion holes 146a and 146b provided in a disk-shaped transmission member 146 fixed to a rotating shaft 76 protruding from the rear surface of the cylinder portion 75 of the key cylinder 20, respectively. Is done. Thereby, as the cylinder part 75 rotates, the piece member 141 also rotates in conjunction with it.

  A pin 141d protrudes from the center of the surface in the back direction which is the base 141a of the top member 141 and is opposite to the surface on which the connecting pieces 141b and 141c are provided. A substantially rhombus cam 147 is provided at the tip of the pin 141d in a direction orthogonal to the axial direction of the pin 141d. The cam 147 rotates with the rotation of the top member 141, contacts the contact portions 150 and 151 of the first contact terminal 142, and the second contact terminals 143 that are spaced apart from the contact portions 150 and 151. , 144 respectively. By this pressing, the first contact terminal 142 is deformed outward and comes into contact with the second contact terminals 143 and 144.

  The first contact terminal 142 is formed in a substantially U shape that is held by an insulating support piece 152 provided on the holding member 145, and is formed so that both end portions 150 and 151 thereof are substantially parallel. . A cam 147 is located between both ends. Both end portions 150 and 151 (hereinafter referred to as contact portions 150 and 151) are pressed outwardly by the rotating cam 147, and are deformed toward the outside to come into contact with the second contact terminals 143 and 144, respectively. Note that the tips of the contact portions 150 and 151 are formed in an arc shape protruding toward the second contact terminals 143 and 144. Thus, by making the front-end | tips of the contact parts 150 and 151 into the circular arc shape which protrudes toward the 2nd contact terminals 143 and 144, the contact parts 150 and 151 of the 1st contact terminal 142, and the 2nd contact terminals 143 and 144 are provided. Can be reliably brought into contact with each other.

  The second contact terminals 143 and 144 have one ends of cables 153 and 154 connected to the game control device 120 fixed thereto, respectively. The second contact terminal 143 is provided outside the contact portion 150 of the first contact terminal 142, and the second contact terminal 144 is provided outside the contact portion 151 of the first contact terminal 142 so as to be separated from each other. Yes.

  For example, when the upper door 4 is replaced, when the locking of the upper door 4 and the main body member 3 by the locking device 50 is released, the unlocking key 22 is inserted after the unlocking key 22 is inserted from the key hole 21 of the key cylinder 20. In FIG. 9, it is rotated in the R direction. As shown in FIG. 9, before and after the unlock key 22 is inserted, the long side direction of the cam 147 is parallel to the contact portions 150 and 151 of the first contact terminal 142 or the second contact terminals 143 and 144. Thus, the first contact terminal 142 and the second contact terminals 143 and 144 are not in contact with each other. That is, the key switch 140 is in an off state.

  When the unlocking key 22 is rotated, the cylinder portion 75 of the key cylinder 20 and the transmission member 146 fixed to the rotating shaft 76 of the cylinder portion 75 rotate together with the cylinder portion 75. Since the connecting pieces 141b and 141c of the top member 141 are respectively inserted into the insertion holes 146a and 146b provided in the transmission member 146, the top member is synchronized with the rotation of the transmission member 146 in the R direction in FIG. 141 also rotates in the same direction. The rotation of the piece member 141 in the R direction in FIG. 9 changes the respective end portions in the long side direction of the cam 147 toward the second contact terminals 143 and 144, and the contact portions 150 and 151 of the first contact terminal 142. Since it becomes longer than the gap, the cam 147 is brought into contact with the contact portions 150 and 151 of the first contact terminal 142, and the contact portion 150 of the first contact terminal 142 is moved in the S direction in FIG. The contact portion 151 is pressed in the T direction in FIG. By the pressing of the cam 147, the tip of the contact portion 150 comes into contact with the second contact terminal 143 and the contact portion 151 comes into contact with the second contact terminal 144 (see FIG. 10). Thereby, the 1st contact terminal 142 will be in the state contacted with the 2nd contact terminals 143 and 144, and electricity supply will be performed. That is, the key switch 140 is turned on. During the rotation operation of the unlocking key, the engagement between the first locking claw 51 and the engagement piece 60 and the engagement between the first locking claw 52 and the engagement piece 61 are respectively released.

  Since the state determination unit 127 determines whether or not the key switch 140 is turned on, the first contact terminal 142 contacts the second contact terminals 143 and 144 and is energized, whereby the key switch 140 is turned on. It determines with it being in an ON state. In response to this determination, the control unit 126 outputs a power supply stop signal to the lamp control device 130 and the sound control device 131. Thereafter, the control unit 126 stops the power supply to the lighting boards 11 and 12 assembled to the upper door 4 in the lamp control device 130, and the sound control device 131 stops the power supply to the speakers 13 and 14, and effects. Regulate the output of the start signal. Thereby, not only the insertion of the unlocking key 22 but also the rotation of the unlocking key 22 is detected, thereby stopping the power supply to the board and electrical components assembled in the upper door 4 and regulating the output of signals. Is possible.

  In the case of the key switch 140 that detects the rotation operation of the unlocking key 22, the shape of the first contact terminal 142 is not limited to a substantially U shape, and may be a plate shape. When the first contact terminal is plate-shaped, it is necessary to fix one end of the cable from the game control device to each of the first contact terminal and the second contact terminal with solder or the like.

  Although not described in detail, the key switch may be configured not only to detect the insertion of the unlocking key or to detect the rotation operation of the unlocking key, but also to a key switch that combines these.

  In this embodiment, the details of the connection between the main body side connector and the door side connector are not touched, but in order to make the fitting of these connectors good when the upper door is closed, the door side connector or It is also possible to bias any one of the main body side connectors toward the other.
