Description

  The present invention relates to a game locking device that locks a front frame of a gaming machine such as a pachinko machine or a slot machine.

  As a locking device for this type of gaming machine, in order to lock the front frame (front door) attached to the front of the main body frame (cabinet) of the gaming machine via a hinge, A locking device that locks a hook-like hook locked to a metal fitting attached to the main body frame side is known from Patent Document 1 below.

  This locking device usually has a vertically long base frame body formed by molding a mounting plate and a support plate into a substantially L-shaped cross section, with the collar portion facing forward on the upper and lower sides inside the base frame body. The locking lock projectingly provided is slidably arranged, and a cylinder lock is attached to the middle part of the mounting plate of the base frame body. The cam plate attached to the tip of the lock shaft is connected to the lock lock, and the cylinder lock The cam plate is rotated by the key operation, the locking rod is slid to move the collar portion up and down, and the engagement with the metal fitting is released to unlock. In addition, a coil spring that urges the hook toward the locking side is hooked on the locking rod, and when the front frame is closed with respect to the main body frame, the hook is slid against the edge of the receiving bracket while sliding. The locking state is established, and the urging portion of the coil spring returns to the locking position and operates so as to be locked.

  By the way, in this type of gaming machine, in recent years, a model in which a large number of balls and coins are paid out is popular when a big winning prize is achieved, and many gaming machines that produce a big winning prize are manufactured. However, since the probability of winning the jackpot is usually determined by the program and memory data in the control circuit, the front frame of the gaming machine is illegally opened regardless of whether the game hall is operating or not operating. An illegal act that illegally obtains a lot of balls and coins has occurred by exchanging circuit parts in the control circuit with illegal parts and playing a game under advantageous conditions.

Almost all gaming machines are equipped with a locking device having the structure described above. If the locking device is not unlocked by operating the cylinder lock using a normal key, the front frame of the gaming machine will be It ’s almost difficult to open. However, there are cases where the locking device is illegally forcibly or illegally unlocked using an illegal key or the like made from a genuine key, and the illegal operation as described above is performed by opening the front frame. For this reason, even when the locking device is unlocked by an unauthorized key or the like that is illegally made from the genuine key, the locking device can be locked by other means to prevent unauthorized unlocking. A device was desired.

  Therefore, conventionally, in a locking device having a structure in which a cam is fixed to a lock shaft of a cylinder lock, the shaft of the cam is engaged with and disengaged from the lock shaft, and an electromagnetic solenoid is attached to the outside of the cam. Patent Document 2 proposes a lock device having a structure in which the cam shaft is engaged with or released from the lock shaft by the electromagnetic solenoid. However, since this conventional locking device has an electromagnetic solenoid attached to the outside of the cam, when this type of locking device is used as a locking device for a gaming machine, the electromagnetic solenoid is removed from the base frame of the locking device. There is a problem that it protrudes into the front frame and easily interferes with various components in the front frame, so that it cannot be used for a locking device of a gaming machine.

  The present invention has been made in view of the above points, and even when a cylinder lock is illegally unlocked using a key, the gaming machine can prevent unauthorized unlocking using other locking means. An object is to provide a locking device.

  In order to achieve the above object, according to the locking device of claim 1 of the present invention, a vertically long main body frame is formed by bending a mounting plate and a support plate into an L-shaped cross section, and upper and lower portions of the support plate of the main body frame. The hook is pivotally supported via a pivot shaft, the upper and lower hooks are connected by a connecting rod slidably disposed along the support plate, and a cylinder lock is attached to an intermediate portion of the main body frame. A cam plate is fixed to the lock shaft of the cylinder lock, an engagement portion with which the cam plate can be engaged is provided on the connecting rod, and the hook is attached to the main body frame side of the gaming machine. In the locking device of the gaming machine that is locked by the stopper, the upper lock shaft and the lower lock shaft are arranged to be linked in the case of the cylinder lock, and the electromagnetic solenoid is arranged in the case, The rotation of the upper lock shaft is linked to the lower lock shaft in accordance with the operation of the electromagnetic solenoid. And wherein the Rukoto.

  In the locking device according to claim 2, the mounting plate and the support plate are bent in an L-shaped cross section to form a vertically long main body frame, and the hook portion is projected forward on the upper and lower sides of the main body frame. The provided locking rod is slidable up and down, the cylinder lock is attached to the middle part of the main body frame, the cam plate is fixed to the lock shaft of the cylinder lock, and the cam plate can be engaged In a locking device of a gaming machine in which a portion is provided on the locking rod and the hook is locked by a locking portion of a metal fitting attached to the main body frame side of the gaming machine, The lock shaft and the lower lock shaft are arranged so as to be able to be linked, an electromagnetic solenoid is arranged in the case, and the rotation of the upper lock shaft is linked to the lower lock shaft according to the operation of the electromagnetic solenoid. Features.

  Here, in the above-described locking device, an electromagnetic solenoid is disposed between the upper lock shaft and the lower lock shaft in the cylinder lock so that the solenoid plunger can be engaged, and when the solenoid plunger of the electromagnetic solenoid is operated, the upper lock shaft is engaged. The shaft and the lower lock shaft can be engaged to transmit the rotation.

  The locking device having the above configuration is vertically attached to the inside of the front door of the gaming machine, and the upper and lower hooks are locked to the locking portions of the metal fittings attached to the cabinet side of the gaming machine for locking. The electromagnetic solenoid of the cylinder lock is electrically connected to a drive circuit connected to a management computer, for example. Since the upper lock shaft and the lower lock shaft of the cylinder lock of the normal locking device are not linked, the cam plate fixed to the lower lock shaft does not rotate even if the key is inserted and the cylinder lock is turned. It cannot move and cannot be unlocked.

  When the front frame is opened, an unlock command signal is output from the management computer to the drive circuit, and the electromagnetic solenoid in the cylinder lock is operated by the drive circuit (a circuit for turning on and off the solenoid power supply). As a result, the upper lock shaft and the lower lock shaft in the cylinder lock are linked, and when the upper lock shaft is rotated by the inserted key operation, the lower lock shaft is rotated, and the cam plate is rotated. It becomes movable. Accordingly, if the key is inserted into the cylinder lock and rotated in this state, the upper lock shaft, the lower lock shaft and the cam plate are rotated in the unlocking direction, and the front door can be unlocked.

  On the other hand, when the unlock command signal is not output from the management computer and the electromagnetic solenoid of the drive unit does not operate, the lock pin locks the cam plate, and even if you try to unlock from the key inserted in the cylinder lock, The cam plate does not move and cannot be unlocked.

  For example, if there is a person who creates an unauthorized key from the genuine key or attempts to unlock it using the genuine key, insert the key into the cylinder lock and turn the cam plate to slide the connecting rod or locking rod. Even if it tries, if the upper lock shaft and the lower lock shaft are not linked by the operation of the electromagnetic solenoid, the locking device cannot be unlocked, and unauthorized unlocking using the key is prevented.

  Moreover, this locking device can be easily implemented structurally by simply replacing the cylinder lock with respect to the existing locking device. Furthermore, because the electromagnetic solenoid is housed in the cylinder lock, the electromagnetic solenoid does not protrude from the locking device, and internal components do not interfere even if the locking device is installed in a very small space in the gaming machine. In gaming machines such as pachinko machines and slot machines, it can be used as a locking device with high security.

  The locking device having the above configuration is fixed vertically via the mounting plate 4 with the hooks 5 and 6 facing the cabinet side of the main body, for example, inside the front door of the slot machine. A receiving metal fitting is fixed to the facing position. The electrical wiring of the electromagnetic solenoid 20 in the cylinder lock 10 is connected to a drive circuit (power supply circuit) (not shown). The drive circuit is configured to be controllable by the management computer, and when the unlock command signal is output from the management computer to the locking device of the gaming machine, the drive circuit operates to drive the electromagnetic solenoid 20. Composed.

  When the front door to which the locking device is attached is closed with respect to the cabinet, the inclined portions of the upper and lower hooks 5 and 6 of the locking device rotate downward while abutting against the locking portions of the receiving metal fittings. When the front end of the hook recess exceeds the locking portion, the hook springs 5 and 6 are locked to the locking portion by operating to return to the horizontal position by the biasing force of the coil spring 35.

  On the other hand, when unlocking the front door of a gaming machine, first, an unlocking command signal for the gaming machine to be unlocked is input to the management computer and the gaming machine is unlocked via the drive circuit. The electromagnetic solenoid 20 of the apparatus is energized. As a result, as shown in FIG. 5, the electromagnetic solenoid 20 operates, the solenoid plunger 23 is attracted and moved to the right side of the drawing, and the end fitting portion 23b is locked down against the biasing force of the coil spring 28. It is made to fit in the fitting part 27b of the shaft 27. At this time, the tip fitting portion 23 a of the solenoid plunger 23 of the electromagnetic solenoid 20 holds the fitting connection with the upper lock shaft 17, so that the upper lock shaft 17 of the cylinder lock 10 is lowered via the electromagnetic solenoid 20. It will be in the state connected with the lock shaft 27.

  Next, when a predetermined key is inserted into the cylinder lock 10 of the locking device and turned to the right, the upper lock shaft 17, the solenoid plunger 23, and the lower lock shaft 27 are integrally rotated in the same direction. The plate 8 rotates in the same direction. As a result, the first engaging portion 8 a of the cam plate 8 engages with the engaging portion 7 b of the connecting rod 7, and slides upward against the biasing force of the coil spring 35. As a result, the upper and lower hooks 5 and 6 are tilted downward, unlocked from the metal fitting, and unlocked. Therefore, when the electromagnetic solenoid 20 is activated and the key is inserted into the cylinder lock 10 and turned, the cam plate 8 rotates, the connecting rod 7 slides upward, and the hooks 5 and 6 tilt. Unlocking is performed.

  On the other hand, when a predetermined key is inserted into the cylinder lock 10 and turned when the electromagnetic solenoid 20 is not in operation, the tip fitting portion 23a of the solenoid plunger 23 is fitted and connected to the upper lock shaft 17 as shown in FIG. However, even if the upper lock shaft 17 of the cylinder lock 10 is turned by a key, the end fitting portion 23b is not fitted with the fitting portion 27b of the lower lock shaft 27, so that the electromagnetic Only the solenoid plunger 23 of the solenoid 20 rotates, and the lower lock shaft 27 does not rotate. Therefore, even if the cylinder lock 10 is turned by the key, the lower lock shaft 27 and the cam plate 8 do not rotate, and the connecting rod 7 and the hooks 5 and 6 do not tilt, so that the locking device is not unlocked.

  As described above, when the electromagnetic solenoid 20 in the cylinder lock 10 is not energized, it is impossible to turn the cam plate 8 to the unlocking side. Therefore, the key is inserted into the cylinder lock 10 and the unlocking operation is performed. However, the cam plate 8 cannot be rotated, and the locked state of the front door is maintained. The unlocking device can be unlocked only by the double operation of the unlocking switch operation by the administrator's management computer and the key operation of the attendant, and the security of the gaming machine can be further improved. Further, since the electromagnetic solenoid 20 is housed in the case 11 of the cylinder lock 10 in the locking device, the electromagnetic solenoid does not protrude to the outside of the cam plate as in the prior art, and the locking device becomes larger or protrudes. Interference between the parts to be played and other parts is avoided, and the locking device can be attached to a very narrow gap between the gaming machines.

  The electromagnetic solenoid 20 has a structure in which the solenoid plunger 23 can rotate within the yoke 21 when energized. However, the electromagnetic solenoid 23 cannot rotate within the yoke 21 when energized. It is also possible to transmit the rotation of the upper lock shaft 17 to the lower lock shaft 27 by rotating the yoke 21 together with the solenoid plunger 23 in the case 11.

  FIG. 6 shows another embodiment. In this example, a smaller electromagnetic solenoid 50 is accommodated in the case 41 of the cylinder lock 40, and normally the rotation of the lower lock shaft 57 is locked by the solenoid plunger 53. When the electromagnetic solenoid 50 is actuated, the lock is released to enable the cylinder lock 40 to be unlocked.

  That is, as shown in FIG. 6, the upper end of the lower lock shaft 57 is fitted and connected to the fitting portion 17b at the lower end of the upper lock shaft 17 of the cylinder lock 40 having the same configuration as described above. The lower lock shaft 57 is disposed at the axial center position of the cylindrical case 41 and is rotatably supported by a fixed support portion 59 fitted to the end portion of the case. A locking piece 56 projects from one side of the lower lock shaft 57, and the electromagnetic solenoid 50 is attached along the axial direction in the vicinity of the lower lock shaft 57 inside the case 41. The solenoid plunger 53 of the electromagnetic solenoid 50 is engaged with the locking piece 56 at the normal time (when power is not supplied). When the solenoid plunger 53 is pulled back during power supply, the engagement with the locking piece 56 is performed. Canceled. The end of the lower lock shaft 57 protrudes to the inside of the main body frame 2, and a cam plate 58 is fixed to the end thereof. The cam plate 58 is provided with a first engaging portion 58a that can be engaged with the engaging portion 7b of the connecting rod 7 and a second engaging portion 58b that can be engaged with the engaging portion 31b of the switch operating rod 31. ing.

  In the locking device having such a configuration, even when an attempt is made to insert a predetermined key into the cylinder lock 40 during normal operation, that is, when the electromagnetic solenoid 50 is in an inoperative state, as shown in FIG. Is engaged with the locking piece 56 of the lower lock shaft 57, the lower lock shaft 57 cannot be rotated, and the locking device cannot be unlocked.

  On the other hand, in the case of unlocking the locking device, in the same manner as described above, for example, an unlocking command signal for a gaming machine to be unlocked by inputting to a management computer is generated, and the gaming machine is The electromagnetic solenoid 50 of the locking device is energized. Thereby, the electromagnetic solenoid 50 operates, the solenoid plunger 53 is sucked and pulled back to the main body side, and the engagement with the locking piece 56 of the lower lock shaft 57 is released. In this state, when a predetermined key is inserted into the cylinder lock 40 of the locking device and turned to the right, the upper lock shaft 17 and the lower lock shaft 57 rotate integrally in the same direction. As a result, the cam plate 58 rotates in the same direction, the first engaging portion 58a of the cam plate 58 engages with the engaging portion 7b of the connecting rod 7, and the connecting rod 7 is slid upward. The hook connected to 7 is tilted, and the front frame is unlocked.

  As described above, even in the present locking device, when the electromagnetic solenoid 50 is not energized, it is impossible to rotate the cam plate 8 to the unlocking side. And the locking device can be unlocked only by the double operation of the key operation of the clerk, and the security of the gaming machine can be further improved. Further, since the electromagnetic solenoid 50 is housed in the case 41 of the cylinder lock 40 in the locking device, similarly to the above, the locking device is not enlarged and components such as the electromagnetic solenoid do not protrude from the main body frame. Therefore, interference between the protruding component and other components is avoided, and the locking device can be attached to a very narrow gap between gaming machines.

  In the above-described two embodiments, the hooks 5 and 6 are pivotally supported on the support plate 3 so as to be tiltable, and the upper and lower hooks 5 and 6 are connected by the connecting rod 7.
