The door opening switch 150 includes a photosensor 151 including a light emitting unit and a light receiving unit (not shown) fixed to the attachment plate 66, and a light shielding plate 152 fixed to the movable plate 61. Further, the door closing switch 200 is slid up and down along the surface of the mounting plate 66 opposite to the mounting side of the movable plate 61, and the photosensor 201 including the light emitting unit 210a and the light receiving unit 201b fixed to the mounting plate 66. A light shielding plate 202 is provided on a second movable plate 67 that is formed to be movable.
Here, the mounting plate 66 is formed with an opening 66A that allows the projections 74a and 74b to pass through the inside when the rotating plate 74 rotates.

Further, the movable plate 61 is formed with an opening 64 through which the protrusion 74a can pass when the rotating plate 74 rotates in the direction indicated by the white arrow in FIG. 8A. When rotating in the direction indicated by the white arrow in FIG. 8A, the projection 74a engages with the opening 64 without interfering with the second movable plate 67 and pushes down the movable plate 61, and the light shielding plate 152 is moved to the photosensor 151. Move to a position outside of As a result, the door opening switch 150 is turned ON, and a drive motor 211 of the automatic opening / closing device 210 described later is driven for a predetermined time to open the lower door 40.
Furthermore, below the opening 64 of the movable plate 61, a second opening 61A is formed through which the protrusion 74b can pass when the rotating plate 74 rotates in the direction indicated by the white arrow in FIG. 8B. The second movable plate 67 has an opening 68 through which the projection 74b can pass as the rotating plate 74 rotates in the direction indicated by the white arrow in FIG. 8B. When the rotating plate 74 rotates in the direction indicated by the white arrow in FIG. 8B, the projection 74b passes through the second opening 61A without interfering with the movable plate 61, and is engaged with the upper end of the opening 68. In addition, the second movable plate 67 is lifted and the light shielding plate 202 is moved to a position where the photosensor 201 is shielded. As a result, the door closing switch 200 is turned ON, and a driving motor 211 of an automatic opening / closing device 210 described later is driven in reverse to be closed for a predetermined time to close the lower door 40.

Since the second movable plate 67 is biased downward by a spring (not shown), after the closing switch 200 is turned ON, the rotational force applied to the rotary plate 74 is lost (that is, the key 7). If you loosen the hand turning), it will move downward and return to its original position. As a result, the protrusion 74b is pushed down to the upper end of the opening 68, and the rotating plate 74 also returns to its original position (position indicated by a thin line in FIG. 8).
(Cylinder lock 70)
As shown in FIG. 5, the cylinder lock 70 is a columnar lock device, and includes a cylindrical outer cylinder 71, an inner cylinder 72 housed in the outer cylinder 71, and a rear (lower side) of the outer cylinder 71. It has a rotating plate 74 provided on the back side of the door 40 (the same applies hereinafter).

The outer cylinder 71 is a hollow cylinder having an opening on the front (front side of the lower door 40; the same applies hereinafter) fixed to the back plate of the lower door 40, and the opening forms a keyhole 44. is doing. A lock release device 90 is attached to the upper rear portion of the outer cylinder 71.
The inner cylinder 72 is a cylinder fitted into the hollow portion of the outer cylinder 71, and is fixed along the inner surface of the outer cylinder 71 so as to be rotatable in the left-right direction in front view. A concave key receiving portion 76 is formed in the front portion of the inner cylinder 72. The concave key receiving portion 76 has irregularities formed outside the circumference.
Here, as shown in FIG. 5, the key 7 used for the cylinder lock 70 is provided with a flat tab portion 79 at one end portion of a cylindrical main body, and a ring-shaped portion at the other end portion. An insertion part 78 having an unevenness formed on the outer periphery is provided. Then, the predetermined key 7 is inserted from the key hole 44, and the insertion portion 78 of the key 7 is inserted into the key receiving portion 76. When the shape matches, the key 7 can be rotated. It rotates inside the outer cylinder 71.

Further, as shown in FIGS. 5 to 7, a rectangular locking hole 75 is provided in the rear portion of the inner cylinder 72. The locking hole 75 is configured to prevent the rotation of the inner cylinder 72 by the stopper 91 of the unlocking device 90 projecting therein.
Further, a rotating plate 74 connected by a shaft 73 is attached to the rear end portion of the inner cylinder 72. As shown in FIG. 5, the rotating plate 74 is a deformed cam type plate member having a protrusion 74a and a protrusion 74b. Then, when the key 7 is inserted into the key hole 44 (with the insertion portion 78 of the key 7 fitted in the key receiving portion 76) and rotated to the right by a predetermined angle, the protrusion 74a is moved to the movable plate. When 61 is pushed down to disengage the hook 62 from the protruding piece 65 and the key 7 is rotated to the left by a predetermined angle, the projection 74b lifts the second movable plate 67 so that the door closing switch 200 is turned on. It has become.

(Key sensor 80)
The key sensor 80 is a contact sensor provided on the inner cylinder 72 and detects whether or not the key 7 is inserted into the key hole 44. Specifically, as shown in FIG. 6, a switch provided at the back of the recess formed in the center of the key receiving portion 76 of the inner cylinder 72 is directed from the end of the insertion portion 78 of the key 7 in the insertion direction. When the protruding projection 77 is pressed, the switch is turned on and the insertion of the key 7 is detected. When the key sensor 80 detects the key 7, an unlocking device 90 described later operates to allow the inner cylinder 72 of the cylinder lock 70 to rotate. On the other hand, when the key sensor 80 does not detect the key 7, the unlocking device 90 does not operate and the inner cylinder 72 of the cylinder lock 70 cannot be rotated.

Here, as shown in FIG. 7, the convex portion 77 does not reach the key sensor 80 unless the insertion portion 78 matches the key receiving portion 76. Further, the inner cylinder 72 cannot be rotated unless the key 7 having the insertion portion 78 whose shape matches the key receiving portion 76 is used. Accordingly, when the proper key 7 is inserted to the proper position, the inner cylinder 72 of the cylinder lock 70 can be rotated to bring the cylinder lock 70 into the unlocked state.
(Unlock device 90)
The unlocking device 90 prevents the rotation of the inner cylinder 72 of the cylinder lock 70 in the locked state, and releases the blocking state of the inner cylinder 72 when the key sensor 80 outputs a detection signal. The inner cylinder 72, and hence the rotating plate 74, can be rotated, and the hook 62 can be moved up and down to allow the lower door 40 to be unlocked.

  Specifically, the lock release device 90 is a device using a solenoid, and is housed in a case fixed to the upper rear end portion of the outer cylinder 71 as shown in FIGS. And a plate-like stopper 91 protruding downward through a through-hole formed in the outer cylinder 71. The stopper 91 has a shape that can be fitted into a locking hole 75 formed in the inner cylinder 72, and projects into the locking hole 75 when the lock release device 90 is in a non-energized state. . On the other hand, when the unlocking device 90 is energized, the electromagnet housed in the case is excited and pulled upward against the pressing force of the spring.

Further, the lock release device 90 is in a non-energized state at the time of locking, that is, when the key sensor 80 does not detect the insertion of the key 7 into the key hole 44, and the stopper 91 is fitted into the locking hole 75. Therefore, the inner cylinder 72 cannot rotate. On the other hand, when the key sensor 80 detects the insertion of the key 7, the lock release device 90 is energized, the stopper 91 is pulled upward, and the engagement between the stopper 91 and the locking hole 75 is released. The inner cylinder 72 can be rotated.
In the above-described lock release device 90, the stopper 91 is projected by a solenoid, but a motor may be used as a drive source for operating the stopper 91. For example, although not particularly illustrated, the stopper 91 moves by meshing between a gear rotated by a motor and a rack provided on the stopper 91, or a hook-like protrusion provided on the tip of the motor shaft is formed on the outer periphery of the inner cylinder 72. You may make it latch to a notch.

(Unlocking and locking the lower door 40)
The unlocking and locking by the lower door lock mechanism 60 having the above configuration will be described.
First, in the locked state, the hook 62 is in the position shown in FIG. 4, and the hook 62 is locked to the protruding piece 65. At this time, as shown by a thin line in FIG. 8B, the tip 74a of the rotating plate 74 is positioned at the upper end of the opening 64 of the movable plate 61, and the door opening switch 150 is in the OFF state. . Further, as shown in FIG. 6, the unlocking device 90 projects a stopper 91 to prevent the inner cylinder 72 from rotating.
Subsequently, when the insertion portion 78 of the predetermined key 7 is inserted into the key receiving portion 76, the key sensor 80 provided on the concave surface of the key receiving portion 76 is turned on by the convex portion 77 of the key 7, and the lock release device 90 is energized. Put it in a state. When the lock release device 90 is energized, the stopper 91 comes out of the locking hole 75 of the inner cylinder 72, and the inner cylinder 72 can be rotated (see FIG. 7). Therefore, when the key 7 is rotated to the right, the rotating plate 74 pushes down the movable plate 61 with the projection 74a engaging the lower end of the opening 64 as shown in FIG. At this time, the hook 62 and the protruding piece 65 are disengaged, and at the same time, the opening switch 150 is turned on. As a result, the automatic opening / closing device 210 operates for a predetermined time, and the lower door 40 rotates in the opening direction. The movable plate 61 pushed downward is raised to the original position by the restoring force of the spring 63, and the lower end portion of the opening 64 pushes the protrusion 74a upward, so that the inner cylinder 72 is moved to the original position. Return to.

  Next, when closing the lower door 40, the key 7 is rotated leftward. As shown in FIG. 8B, the rotating plate 74 has the projection 74 b engaged with the upper end portion of the opening 68 of the second movable plate 67 to push down the second movable plate 67. At this time, the closing switch 200 is turned on. As a result, the automatic opening / closing device 210 reversely operates for a predetermined time, and the lower door 40 rotates in the closing direction. The second movable plate 67 pulled upward is lowered to the original position by a restoring force of a spring (not shown), and the upper end portion of the opening 68 pushes the projection 74b downward, so that the inner cylinder 72 is originally moved. Return to position. When the lower door 40 is rotated to the position where it covers the front of the housing 1, the hypotenuse of the hook 62 comes into contact with the protruding piece 65, whereby the movable plate 61 is pushed down and the hook 62 and the protruding piece 65 are engaged. To do. If the key 7 is pulled out from the keyhole 44 when the lower door 40 is closed, the key sensor 80 is turned OFF and the energization to the lock release device 90 is stopped. The lock release device 90 protrudes the stopper 91 to prevent the inner cylinder 72 from rotating, and the lower door 40 is locked.

(Other forms of key sensor 80 and key 7)
By the way, when the key sensor 80 is formed as described above, if the key 7 has been stolen or a matching key has been created, an unauthorized opening by a third party unless the lock itself is replaced. The lock cannot be prevented. Therefore, the key sensor 80 and the key 7 may be formed in a configuration capable of randomly changing a light emitting / receiving pattern to be described later, as shown in FIGS.
That is, as the key sensor 80, a light emitting unit 81 having a plurality of light emitting elements and a light receiving unit 82 having a plurality of light receiving elements capable of receiving light emitted from the plurality of light emitting elements are provided. On the other hand, the cylinder lock 70 uses a key 7 ′ having a translucent portion 84 in the plate-like insertion portion 78, and the inner cylinder 72 is a key having a rectangular hole in which the plate-like insertion portion 78 can be inserted. A receiving portion 76 is provided. As shown in FIG. 10, the light emitting unit 81 and the light receiving unit 82 are installed outside the slit provided on the side surface of the outer cylinder 71, and the insertion portion 78 of the key 7 ′ is inserted into the key receiving portion 76. The light emitted from the light emitting portion 81 is formed so as to be able to reach the light receiving portion 82 through the light transmitting portion 84.

In addition, the light emitting unit 81 may emit any one, two, or all of the light emitting elements according to a preset light emitting pattern stored in the control unit (lock control device 100). And the light receiving part 82 is in a state where any one or two of the light receiving elements receive light from the light emitter 81 with the key 7 'inserted in the key receiving part 76. A predetermined detection signal is output. Then, when the light receiving unit 82 outputs an appropriate detection signal based on a preset light receiving pattern stored in the control unit, the unlocking device 90 is activated, and the inner cylinder 72 of the cylinder lock 70 is moved. It can be rotated.
Here, the light transmitting portion 84 may be a hole 85 as shown in FIG. 12A or a notch 86 as shown in FIG. The translucent part 84 is provided at a position where light emitted from the light emitting element of the light emitting part 81 can pass when the key 7 ′ is inserted into the key receiving part 76. At least one of the light emitting elements is provided. Is not provided with a corresponding translucent part 84. That is, the light transmitting portion 84 is formed so that the light emitted from all the light emitting elements does not pass through at the same time. The light emission pattern of the light emitting unit 81 and the light reception pattern of the light receiving unit 82 are set so as not to match. That is, the light emitted from the light emitting unit 81 not only passes through the translucent part 84 of the key 7 ′ inserted into the key receiving part 76, but is also shielded by a portion other than the translucent part 84 of the key 7 ′. The light receiving pattern is formed. That is, the installation number and installation position of the light transmitting parts 84 are set according to the light emission pattern of the light emitting part 81 and the light reception pattern of the light receiving part 82.

  Note that the key 7 ′ may have a fitting member 87 fitted in a hole 85 formed in the insertion portion 78, as shown in FIG. The holes 85 are provided corresponding to all the light emitting elements. As the fitting member 87, a light transmitting member 87a made of a transparent material and a light shielding member 87b made of an opaque material are provided. The hole 85 into which the translucent member 87a is fitted becomes the translucent portion 84. If formed in this way, a plurality of types of translucent portions 84 can be obtained with a single key 7 depending on which of the holes 85 corresponding to the light emitting elements is fitted with the translucent member 87a and which is fitted with the light shielding member 87b. Can be created. Instead of providing the translucent member 87a, the translucent portion 84 may be formed as a hole 85, and the light shielding member 87b may be fitted only where it is not desired to be the translucent portion 84.

  As described above, a plurality of different light emission patterns can be set by determining the light emitting elements to emit light, and a plurality of different light emission patterns can be set by determining the light receiving elements in which light reception is effective. . Then, the mode of the translucent part 84 of the key 7 ′ is determined in order to realize the light receiving pattern set by the set light emission pattern. Therefore, if a plurality of light emitting / receiving pattern data and a key 7 'corresponding thereto are prepared, even if the key 7' is stolen, different light emitting / receiving pattern data is given to the control unit (lock control device 100). By inputting, it is possible to cope quickly without changing the lock. In addition, for example, by changing the light receiving / emitting pattern randomly on a daily basis, it becomes difficult to decode the light receiving / emitting pattern, and security can be improved.

The key sensor 80 includes an energizing switch 83 (see FIG. 10) provided at the back end of the key receiving portion 76 and a convex portion 77 (see FIG. 12) provided at the end of the insertion portion 78 of the key 7 ′. ) May be energized by pressing, and the light emitting unit 81 may emit light. By forming in this way, the light emitting element does not always emit light and is useful for energy saving.
(Another example of unlocking device 90)
Further, in the above-described embodiment, the above-described lock release device 90 maintains the locked state by preventing the rotation of the inner cylinder 72 of the cylinder lock 70, and when the proper insertion of the key 7 is detected. Although it was positioned as a prohibition release means that allows the rotation of the cylinder 72, the cylinder lock 70 is formed so that the rotating plate 74 rotates regardless of the rotation of the key 7, and the unlocking device 90 is actively unlocked. You may form so that it may function as the cancellation | release means to perform. That is, as long as the proper key 7 is inserted into the key hole 44, the inner cylinder 72 may be automatically unlocked without being rotated.

  Specifically, as shown in FIG. 9, a motor 92 is embedded on the rear side of the inner cylinder 72, the motor shaft of the motor 92 is connected to a shaft 73, and the drive of the motor 92 is directly transmitted to the rotary plate 74. It can be made like this. In the locked state, that is, when the predetermined key 7 is not inserted into the key receiving portion 76, the motor 92 is positioned so that the protrusion 74a of the rotating plate 74 is engaged with the upper end portion of the opening 64 of the movable plate 61. The drive is stopped. That is, the movable plate 61 is lifted upward by the protrusion 74a. When the key sensor 80 detects an appropriate key, the driving is started, and the driving is stopped by rotating the rotating plate 74 by a predetermined angle. Thereby, the protrusion 74a of the rotating plate 74 pushes down the lower end portion of the opening 64, and the movable plate 61 is moved downward to release the engagement between the hook 62 and the protruding piece 65. In the state where the key 7 is still inserted in the key receiving portion 76, the motor 94 is not driven, and when the detection signal output of the key sensor 80 is stopped by pulling out the key 7 from the key receiving portion 76, this time By rotating in the reverse direction, the rotating plate 74 is rotated to the position at the time of locking.

When unlocking the lower door 40 having the unlocking device 90, the key sensor 80 is activated by inserting a predetermined key 7 into the key hole 44 to detect the key, and the motor 92 is driven to rotate the rotating plate. By rotating 74, the hook 62 and the protruding piece 65 are disengaged, and the door can be opened. On the other hand, when locking the lower door 40, the lower door 40 is closed with the key 7 inserted into the key hole 44, and when the key 7 is removed from the key hole 44, the motor 94 is driven reversely to reverse the rotating plate 74. The movable plate 61 is pulled up by the protrusion 74a engaged with the opening 64 and moved upward, the hook 62 and the protruding piece 65 are engaged, and the door is locked.
Also in the above-described unlocking device 90, when the key 7 is rotated in a predetermined direction, the rotating plate 74 is rotated until the hook 62 is in the unlocked position, and when the key 7 is rotated in the reverse direction, the hook 62 is in the locked position. The rotating plate 74 may be formed so as to rotate.

(Automatic switchgear 210)
Next, details of the automatic opening / closing device 210 will be described.
As shown in FIG. 13, the automatic opening / closing device 210 is a rotational drive device including a gear box 213 provided in the lower door 40, a drive motor 211 provided in the housing 1, and a connecting shaft 212.
First, as shown in FIG. 13, the lower door engaging portion 46 in the present embodiment includes an opening 47A provided in the rear vertical frame 47 on the back side of the lower door 40, the rear vertical frame 47 and the lower door. The receiving plate 48 is fixed to 40 side plates and extends in the horizontal direction. The lower door 40 is attached to the housing 1 by supporting the lower surface of the receiving plate 48 on the upper surface of the housing hinge 19. When the door 40 is rotated, the housing hinge 19 does not interfere with the rear vertical frame 47 through the opening 47A.

  The drive motor 211 is fixed to the lower side of the lower casing hinge 19, and its motor shaft is fixed to a connecting shaft 212 that penetrates the upper and lower casing hinges 19. Further, as shown in FIG. 14, a gear 214 that meshes with a gear 215 provided inside a gear box 213 fixed to the upper surface of the receiving plate 48 is fixed to the connecting shaft 212, and is driven by the drive motor 211. The connecting shaft 212 and the gear 214 are configured to rotate. 14A is a cross-sectional view of the hinge portion when the lower door 40 is closed, and FIG. 14B is a view taken along the line II-II in FIG. 14A. When the gear 214 rotates, a rotational force is transmitted to the gear 215, and the lower door 40 to which the gear box 213 is fixed rotates about the connecting shaft 212.

Further, the automatic opening / closing device 210 is configured such that when the drive motor 211 stops driving, a force is applied in a direction in which the lower door 40 is rotated to rotate the gear 215 and the gear 214, thereby causing the drive shaft to idle. Door rotation lock means 230 for blocking is provided.
As shown in FIG. 14, the door rotation lock unit 230 includes a solenoid 232 provided in the rear vertical frame 47 and a substantially L-shaped locking plate 231 that is operated by the solenoid 232. The locking plate 231 is installed so that the gear 214 is positioned at a portion exposed above the gear box 213, and when the driving motor 211 stops driving, the bent distal end portion has a bent end as shown by a solid line in FIG. Engagement with the teeth of the gear 214 prevents the rotation of the gear 214. Further, while the drive motor 211 is driven (including reverse rotation drive), as shown by a two-dot chain line in FIG. 14A, the engagement with the gear 214 is disengaged and the rotation of the gear 214 is not interfered. ing. Because of this formation, the lower door 40 cannot be rotated because the gear 215 is engaged with the gear 214 that is prevented from rotating when the drive motor 211 is stopped.

Further, although not particularly illustrated, the automatic opening / closing device 210 is provided with a rotation detection sensor for stopping the driving when a certain load or more is applied to the motor 211. As a result, when there is some trouble in the opening / closing operation of the lower door (40), for example, when the door is caught by something, or when the locking device 190 works and the hook 62 and the protruding piece 65 collide, If the motor 211 does not close, the motor 211 automatically stops driving.
In the illustrated example, the gear 214 fixed to the connecting shaft 212 directly meshes with the gear 215, but one or more connecting gears may be provided between the gear 214 and the gear 215.
The door rotation lock means 230 may be a device different from the drive motor 211 as described above, but the drive motor 211 itself may be formed so that the drive shaft does not rotate when the drive is stopped. . When formed in this way, the automatic opening / closing device 210 is not particularly shown in addition to the one housed in the hinge part, but pushes or retracts the anti-hinge side of the lower door 40 by the rotation of the drive shaft of the drive motor 211. For example, an arc-shaped rack plate that is movable may be provided. In this case, the drive motor 211 is provided on the bottom plate 15 of the housing 1 and the end of the rack plate is fixed to the lower end of the lower door 40 so that the rack plate does not get in the way when the door is opened.

(Lock control device 100)
The lock control device 100 is for controlling the operation of the unlocking device 90 and the automatic opening / closing device 210, and is a control board provided separately from the control device of the slot machine S, although not particularly shown. As shown in FIG. 16, the lock control device 100 includes a determination unit 110 and an opening / closing control unit 120, and includes a key sensor 80, a large opening switch 130, a timer 140, a door opening switch 150, and a door closing switch 200. Is received, and the operation of the drive motor 211 of the unlocking device 90 and the automatic opening / closing device 210 is controlled. The door rotation lock means 230 is activated by receiving a signal from the drive motor 211.

Here, the large opening switch 130 is, for example, a switch provided on the back side of the lower door 40 or the inside of the housing 1, and is a lower switch rotated by a predetermined angle in the opening direction by the automatic opening / closing device 210. The door 40 is further rotated to open the lower door 40 fully. The timer 140 can be, for example, a pulse counter provided in the lock control device 100, a CR timer provided in the vicinity of the automatic opening / closing device 210, or the like. It is for measuring.
The opening / closing control means 120 drives the driving motor 211 for a predetermined time to open the lower door 40 to a predetermined angle when the opening switch 150 is turned ON and when the large opening switch 130 is operated. On the other hand, when the door closing switch 200 is operated or when a certain time has elapsed (when the time count of the timer 140 exceeds a certain value), the drive motor 211 is driven in reverse to close the lower door 40. It is.

By the way, the key sensor 80, the lock release device 90, and the lock control device 100 are connected to an uninterruptible power supply connected to an external power supply, separately from the power supply of the slot machine S, as shown in FIG. . The external power supply and the uninterruptible power supply are arranged in the island facility of the game arcade where the slot machine S is installed. The key sensor 80, the lock release device 90, and the lock control device 100 operate even when the main power supply of the slot machine S is OFF or when the external power supply is OFF.
(Open / close control of lower door 40)
The opening / closing control of the lower door 40 by the lock control device 100 having the above configuration will be described based on the flow of FIG.

First, in step 100 in FIG. 21, it is determined whether or not the key sensor 80 is turned on. That is, it is determined whether or not the key 7 having the convex portion 77 that matches the key receiving portion 67 has been inserted into the key hole 44. If the key sensor 80 is turned on, the process proceeds to the next step 101.
In step 101, the lock of the cylinder lock 70 is released. That is, the lock release device 90 is energized, the stopper 91 comes out of the locking hole 75, and the inner cylinder 72 can be rotated. Then, the process proceeds to the next step 102.
In step 102, when the door opening switch 150 is turned on (that is, by turning the key 7 clockwise), the drive motor 211 of the automatic opening / closing device 210 is driven. When the drive motor 211 is in the drive state, the door rotation lock means 230 releases the lock (the same applies hereinafter). Then, the drive motor 211 starts to rotate in the direction of opening the door. At the same time, the timer 140 starts time counting, and the drive motor 211 stops after being driven for a predetermined time. This “predetermined time” can be set to a time during which the lower door 40 opens to an opening angle of 45 degrees, for example, by driving the drive motor 211. Further, when the drive motor 211 stops driving, the door rotation lock unit 230 is locked and prevents the drive shaft from rotating. For this reason, the lower door 40 cannot be manually opened and closed (the same applies hereinafter). Then, the process proceeds to the next step 103.

In step 103, it is determined whether or not the key sensor 80 is turned off. This is for checking whether the key 7 is pulled out with the lower door 40 opened. If the key sensor 80 is not OFF, the process proceeds to the next step 104.
In step 104, it is determined whether or not the large opening switch 130 is turned on. When the large opening switch 130 is turned on, that is, when the large opening switch 130 is operated, the process proceeds to the next step 105.
In step 105, the drive motor 211 of the automatic opening / closing device 210 starts to rotate in the direction of opening the door. The drive motor 211 stops after the lower door 40 is opened to a maximum opening angle, for example, 90 degrees. Here, the timer 140 resets the time count and starts counting from zero again. Whether or not the maximum opening angle has been reached may be determined by the time count of the timer 140, or a limit switch may be provided on the lower door 40 or the housing 1. Then, the process proceeds to the next step 106.

If the large opening switch 130 is not ON in step 104, the process skips step 105 and proceeds to step 106.
In step 106, it is determined whether or not the closing switch 200 is turned on. If the closing switch 200 is not ON, the process proceeds to the next step 107.
In step 103, if the key sensor 80 is turned off, that is, if the key 7 is pulled out with the lower door 40 opened, the process skips steps 104 to 106 and proceeds to step 107.
In step 107, it is determined whether or not a certain time has elapsed since the drive motor 211 was driven, that is, since the lower door 40 was first opened or the lower door 40 was opened by the large opening switch 130. . The predetermined time is preferably a short time of about several tens of seconds, assuming that the door is opened for the first time when the door is opened (small opening), for example, for replenishing medals to the hopper or releasing clogged medals. When the door is opened by the large opening switch 130, it is preferable to set the opening time longer than the small opening time, for example, assuming maintenance of the hopper unit or replacement of the lower panel. Even if such a setting is made, there is no inconvenience because it is unlikely that the door will be greatly opened when performing an illegal act. A “timer stop switch” that can be operated only when the door is fully opened may be provided so that the time count is stopped to prevent the door from closing during the maintenance of the gaming machine. If the predetermined time has not elapsed, the process returns to step 103. On the other hand, if the predetermined time has elapsed, the process proceeds to the next step 108.

In step 108, a predetermined error warning is made. As warnings, for example, an error is displayed on the display unit 32 of the slot machine S, a warning sound is emitted from the speaker 35, the lamp of the decoration unit 33 is blinked, or conversely, the fuse is disconnected and the lamp is disconnected. Or turn off the lights and give notifications. At the same time as the error warning, the slot machine S enters a game-disabled state (invalid operation of the start switch 4141C and no medal acceptance). Then, the process proceeds to next Step 109.
If the closing switch 200 is turned on in step 106, the process skips steps 107 and 108 and proceeds to step 109.

In step 109, the drive motor 211 of the automatic opening / closing device 210 starts to rotate in the direction of closing the door. The drive motor 211 stops after being driven for a predetermined time. This predetermined time is a time necessary and sufficient for the lower door 40 to rotate to a position where the lower door 40 is in the closed state (locked state). Alternatively, the drive of the motor 211 may be stopped by the limit switch when the lower door 40 is closed. In this way, the lower door 40 opens the door with the key 7 attached when the key sensor 80 is turned off when the door is opened, that is, when the key 7 is removed, regardless of the closing switch 200. In this case, after a predetermined time elapses, a predetermined warning is given and then forced closure is performed.
Here, when the lower door 40 is opened, the key 7 is pulled out from the keyhole 44, or the lower door 40 is opened without using the key 7 by any means. When forcibly closing, the lock release device 90 is in a locked state (the stopper 91 protrudes). Therefore, the movable plate 61 of the lower door lock mechanism 60 cannot move up and down, and the hook 62 and the protruding piece 65 are in contact with each other, and the lower door 40 is not locked and has a gap between the housing 1 and the housing 1. Stays closed. Of course, in this state, a game cannot be performed. If the motor 211 continues to be driven without closing the lower door 40, a constant load is applied to the motor 211, so that the rotation detection sensor is activated and the driving of the motor 211 is stopped.

On the other hand, when the lower door 40 is forcibly closed after a predetermined time has passed with the key 7 inserted into the keyhole 44, the lock release device 90 is in the unlocked state (the stopper 91 does not protrude), so the lower door 40 Closes the front surface of the housing 1 and simultaneously the movable plate 61 moves up and down to engage the hook 62 and the protruding piece 65, and the lower door 40 is closed and locked.
When the reverse drive of the drive motor 211 is stopped, the process proceeds to the next step 110.
In step 110, it is determined whether or not the key sensor 80 is turned off. That is, it is confirmed whether or not the key 7 has been pulled out from the keyhole 44. If the key sensor 80 is not turned off, the process returns to step 110. On the other hand, if the key sensor 80 is turned off, the process proceeds to the next step 111.

If the key sensor 80 is not ON in step 100, that is, if the predetermined key 7 is not properly inserted into the key hole 44, the process proceeds to step 111.
In step 111, the cylinder lock 70 is locked. That is, the lock release device 90 is deenergized, the stopper 91 protrudes into the locking hole 75, and the inner cylinder 72 cannot be rotated. Then, the door opening / closing control ends.
Thus, according to the present embodiment, the lower door 40 can be rotated only by driving the drive motor 211, and when the lower door 40 is opened, the door opening switch 150 is not turned ON by operating the key. Since the drive motor 211 does not operate, the door does not open, and the door cannot be closed unless the door closing switch 200 is operated even when the door is closed because the drive motor 211 does not operate. Therefore, it becomes difficult to open and close the door without using the predetermined key 7. In addition, if the door is left open, the door is forcibly closed by the operation of the drive motor 211. For example, even if you make a lock key and open the door, the door is closed during the goto action. There is a high possibility that it will end. Therefore, it becomes more difficult to perform an illegal act by opening the door, and it also serves as a deterrent to the act.

In the above embodiment, the door closing switch 200 is formed to be turned on by rotating the key 7 in the reverse direction. However, the door closing switch is not limited to such a configuration. It may be a push switch provided in the inside of the housing 1 or the back surface of the lower door 40 that can be operated when opened. In this case, the operation of this switch is enabled only when the key sensor 80 detects the insertion of the key 7, and the switch can be depressed even if the switch is pressed without inserting the key 7 into the key hole 44. The door 40 does not rotate in the closing direction.
In the above-described embodiment, the lower door 40 is provided with the cylinder lock 70 and unlocked by the key 7, and the lower door 40 is opened so that the upper door 30 can be unlocked. However, the upper door 30 may be provided with a lock similar to the cylinder lock 70 so that the lower door 40 can be locked and unlocked separately. The lock mechanism 6 is not limited to the one described in the above embodiment, and may be any form that can be opened and closed with the key 7 inserted. For example, by operating the key 7, the convex portion protrudes into the concave portion provided on the inner side of the side plate 16 of the housing 1 to be in a locked state, and the convex portion is activated by the operation of the unlocking device 90 based on the insertion of the key 7 May be formed so as to escape from the recess.

  Furthermore, it goes without saying that the present invention can also be used in slot machines in which the front door 3 is a single door, and game machines other than the slot machine.
