[0012]
The gaming machine locking device 7 according to the present embodiment is for locking and unlocking the front panel 5 with respect to the housing 3. As shown in FIG. 3, the gaming machine locking device 7 includes a cylinder lock 11 having a crankshaft 9, a pressing claw 13 (see FIG. 1), a swing claw 15, a slide plate 17, and a swing regulation. It has a claw 19 as a main component.
[0013]
The front panel 5 has one end in the left and right direction rotatably supported by the housing 3 via a hinge (not shown), and the other end in the left and right direction is opened and closed with respect to the housing 3. The cylinder lock 11 is attached to the other end of the front panel 5 that is opened and closed, and exposes a keyhole 11 a on the front surface of the front panel 5. That is, the cylinder lock 11 rotates around the center of rotation 21 (see FIG. 1) of the gaming machine 1 in the front-rear direction. The crankshaft 9 has a base shaft 9a fixed to a rotating shaft 11a of a cylinder lock 11 shown in FIG. 4, and a distal shaft 9b bent in a crank shape is eccentric with respect to the base shaft 9a. The crankshaft 9 has a tip shaft 9 b protruding toward the housing 3.
[0014]
The pressing claws 13 are located above and below the rear surface of the front panel 5 and fixed. The pressing claw 13 has an L-shape whose tip is bent downward, for example, and protrudes toward the housing 3 side. The pressing claw 13 presses the rocking claw 15 with an L-shaped tip 13a and locks the rocking claw 15 with the L-shaped tip 13a, as described later in detail.
[0015]
A pair of rocking claws 15 are provided in the housing 3 corresponding to the respective pressing claws 13. A substantially L-shaped fixing plate 23 is fixed to the housing 3, and the swinging pawl 15 is swingably attached by a support pin 25 penetrating through a side plate of the fixing plate 23. As shown in FIG. 1, the axis of the support pin 25 is in the left-right direction of the gaming machine 1.
[0016]
As shown in FIGS. 5 and 6, the swing claw 15 has a claw portion 15a separated by a gap 15b. A projection 15c protrudes from the opposite side of the claw portion 15a. Further, the rear surface of the projection 15c is a hook 15d (see FIG. 6) formed by connecting the separated claws 15a. Further, the contact portion 15e is provided with a concave gap portion in a direction substantially the same as the extension direction of the claw portion 15a. As shown in FIG. 5A, the swing claw 15 is locked with the pressing claw 13 by a claw portion 15a. Then, it is fitted into the concave gap between the contact portion 15e.
[0017]
The base plate 27 shown in FIG. The slide plate 17 is slidable in the vertical direction of the gaming machine 1 by engaging the slots 17a, 17b with a pair of regulating pins 29a, 29b provided upright on the base plate 27. A spring 31 is stretched between the base plate 27 and the slide plate 17, and the spring 31 urges the slide plate 17 in one direction, that is, downward in FIG. The slide plate 17 is provided with an engagement hole 33 having a corner 33a shown in FIG. The tip shaft 9b of the crankshaft 9 enters the engagement hole 33. The tip shaft 9b that has entered the engagement hole 33 is disposed at the corner 33a, thereby restricting the slide plate 17 from sliding in the vertical direction.
[0018]
As shown in FIG. 4B, the tip shaft 9 b of the crankshaft 9 is fitted to the crankshaft 9 so as to prevent withdrawal and withdrawal and to move forward and backward. It is biased in the protruding direction. Thus, when the front panel 5 is closed, even if the tip shaft 9b abuts on a portion other than the engagement hole 33 due to poor sliding, the tip shaft 9b compresses the compression spring 35 and enters the inside of the crankshaft 9. The crank shaft 9 or the slide plate 17 is prevented from being retracted and damaged.
[0019]
The swing regulating claw 19 is fixed to upper and lower ends of the slide plate 17 as shown in FIGS. Further, as shown in FIG. 7, the swing regulating claw 19 is guided in a sliding direction through a long hole 19a by a pair of support pins 37a and 37b penetrating through the side plate of the fixed plate 23. The swing regulating claw 19 is formed in a substantially L-shape. As shown in FIG. 8, the tip 19 b abuts on the projection 15 c of the swing claw 15 to regulate the rotation of the swing claw 15. Further, as shown in FIGS. 9 and 10, the swing regulating claw 19 can enter the gap 15 b of the swing claw 15 by sliding the slide plate 17. As a result, the swing claw 15 does not come into contact with the swing restricting claw 19 and the swing claw 15 can rotate counterclockwise as shown in FIGS. 9 and 10.
[0020]
Further, when the swing claw 15 rotates while the swing claw 15 enters the gap 15b, in other words, when the front panel 5 is opened, the swing claw 19 rotates together with the pressing claw 13 and rotates. Is locked to a hook 15d of the swinging claw 15 (a state shown in FIG. 9). Thus, the swing regulating claw 19 is locked to the swinging claw 15 in the swinging state, and regulates the sliding of the slide plate 17 in one direction (downward in FIG. 12). That is, the slide plate 17 is held while being slid upward. This holding is released when the swinging claw 15 is pressed by the pressing claw 13 and rotated. When the shoulder 19c comes off the hook 15d, the slide plate 17 is again slid downward by the urging force of the spring 31 (the state shown in FIG. 1).
[0021]
Accordingly, the swinging claw 15 swings by the pressing of the pressing claw 13 accompanying the closing movement of the front panel 5, and when the front panel 5 is closed, the projection 15 c abuts on the distal end portion 19 b of the swing regulating claw 19. By restricting the swing, the pressing claw 13 is locked, that is, held by the swing claw 15, and the opening movement of the front panel 5 is regulated.
[0022]
Next, the operation of the gaming machine locking device having the above configuration will be described.
11 is an operation explanatory diagram when the slide plate is slid upward, FIG. 12 is an operation explanatory diagram when the front panel is opened, and FIG. 13 is an operational explanatory diagram when the front panel is closed.
[0023]
As shown in FIG. 1, when the front panel 5 is closed, the slide plate 17 is disposed below by the urging force of the spring 31, and the tip 19 b of the swing regulating claw 19 contacts the projection 15 c of the swing claw 15. 6 (see FIG. 6) to prevent the rotation of the swinging pawl 15. Therefore, the front panel 5 in which the pressing claw 13 is locked to the swinging claw 15 cannot be opened from the housing 3 and is locked.
[0024]
On the other hand, when opening the front panel 5 and inserting the duplicate key 41 into the cylinder lock 11 as shown in FIG. 11 and turning the duplicate key 41, the crankshaft 9 rotates. Then, the slide plate 17 is pushed upward by the crankshaft 9 through the engagement hole 33 against the urging force of the spring 31. When the slide plate 17 slides upward, the contact between the distal end portion 19b of the rocking claw 19 and the projection 15c of the rocking claw 15 is released, and at the same time, the rocking control claw 19 is moved into the gap 15b between the rocking claw 15. To enter. Thereby, the regulation of the rocking claw 15 is released, and the rocking claw 15 is in a rockable state.
[0025]
In this state, as shown in FIG. 12, when the front panel 5 is opened by hand, the swinging claw 15 rotates with the pressing claw 13 moving away. As the swing claw 15 rotates, the hook 15d is hooked on the shoulder 19c of the swing regulating claw 19 (see FIG. 9). Thereby, the slide plate 17 is hung on the swinging pawl 15 and held at the upper slide position. The crankshaft 9 is removed from the engagement hole 33 when the front panel 5 is opened. After opening the front panel 5, the duplicate key 41 is turned in the opposite direction again and pulled out of the cylinder lock 11. Thereby, the crankshaft 9 is rotated and returned to the original position, that is, a position where the crankshaft 9 can enter the engagement hole 33 of the slide plate 17 slid downward.
[0026]
Next, as shown in FIG. 13, when the front panel 5 in the open state is closed, the pressing claw 13 presses the contact portion 15e of the swinging claw 15 with the closing movement. The swing claw 15 releases the hook between the hook 15d and the shoulder 19c by swinging. As a result, the slide plate 17 is slid downward again by the urging force of the spring 31. Further, when the front panel 5 is closed, the crankshaft 9 enters the engagement hole 33 of the slide plate 17 slid downward.
[0027]
When the slide plate 17 slides downward, the swing regulating claw 19 again comes into contact with the projection 15 c of the swinging claw 15, and the swinging claw 15 is locked with the pressing claw 13 and cannot swing. As a result, as shown in FIG. 1, the pressing claw 13 of the front panel 5 is again locked to the swinging claw 15 that has become unable to swing, and the front panel 5 is locked to the housing 3 side. Become.
[0028]
According to the locking device 7 for a gaming machine, the swinging pawl 15 locked to the pressing claw 13 is locked by the swing restraining claw 19, and the slide plate 17 to which the swing restraining claw 19 is fixed is engaged with the engagement hole 33. And is locked to the crankshaft 9. That is, since the crankshaft 9 has entered the corner 33a of the engagement hole 33, the slide plate 17 cannot slide unless the cylinder lock 11 is unlocked and rotated.
Therefore, even if a wire or the like is inserted from the gap between the housing 3 and the front panel 5, the swinging pawl 15 is restricted from swinging by the swing regulating pawl 19, and the slide plate 17 is cranked through the engaging hole 33. Since the slide is regulated by the shaft 9, the locking between the pressing claw 13 and the swinging claw 15 cannot be directly moved to be released, and the unlocking of the front panel 5 due to such illegal acts is prevented. . Further, by closing the front panel 5, the swinging pawl 15 is pressed by the pressing pawl 13 and rotates in the locking direction, so that the front panel 5 can be locked only by closing the front panel 5. Become.
[0029]

Therefore, when the front panel 5 is closed, the pair of pressing claws 13 The lock is locked by the pair of swing claws 15. Therefore, the two swinging claws 15 are operated by using one slide plate 17, and the front panel 5 and the housing 3 can be locked by the two sets of the pressing claws 13 and the swinging claws 15. The locking reliability of the panel 5 is improved.
[0030]
In the above-described embodiment, a case has been described as an example in which the locking and locking portion including the pressing claw 13, the swinging claw 15, and the swing regulating claw 19 is disposed at two locations above and below the slide plate 17. In the gaming machine locking device according to the present invention, the locking portion may be provided at one location, or may be provided at two or more locations.
[0031]
Further, the cylinder lock 11 is configured to execute a reset operation of a game control board or the like as an internal device by rotating in a direction opposite to the unlocking direction.
[0032]
Furthermore, the above-described gaming machine locking device 7 has been described as an example of the gaming machine 1 that opens and closes only the front panel 5 with respect to the housing 3, but the gaming machine locking device according to the present invention is not limited to this. For example, the present invention may be applied to a gaming machine having a structure in which a front door that can be opened and closed is further provided on the front surface of the front panel 5. In this case, the cylinder lock 11 can be configured such that the front panel 5 is unlocked by one rotation and the front door is unlocked by the other rotation by adding a separate locking mechanism for the front door.
