The cable hook 35 etc. are integrally molded,
An insertion opening 36 through which a connector connected to the connector receiving portion 27 is inserted into a side wall facing the power supply unit 3 in the mounted state.
To form In the present embodiment, a part of the ceiling portion 24a is stepped, and the connector side wall 4
0, a connector room 41 is formed.
The insertion opening 36 is formed by notching a portion of the side wall 1 in a rectangular shape. The insertion opening 36 is provided only with an operating tool having a cross-sectional area smaller than the cross-sectional area of the connector 42 from the outside in a state where the upper lid member 24 and the bottom lid member 25 are held in a closed state by the locking member 23. An opening form in which the lock mechanism can be operated, that is, a cutout opening having a size and a shape in which the lock mechanism can be operated only with the operating tool.

When the connector 42 is fitted into the connector receiving portion 27, the two contacts are electrically connected and electrically connected, and the connection state is maintained by a lock mechanism. Since the connector 42 facilitates the connection of the power supply cable 20, the one used for the pachinko machine 1 generally has a cross-sectional area, particularly a vertical dimension of about several mm less than 1 cm. Smaller than adult fingertips. Therefore, the insertion opening 3 formed in the game control board case 26
In the present embodiment, the size of the connector 6 is also slightly larger than the cross-sectional area of the connector 42 so that the lock mechanism can be operated only by an operating tool having a cross-sectional area smaller than the cross-sectional area of the connector 42. Specifically, the left and right dimensions of the insertion opening 36 are two to three millimeters added to the left and right dimensions of the connector 42, and the vertical dimension is set to less than 1 cm.

As shown in FIG. 7, the lock mechanism according to the present embodiment includes a locking portion 44 provided integrally on the connector 42 side and a locking receiving portion 45 provided integrally on the connector receiving portion 27 side. Consists of

The locking portion 44 has an elastic support piece 46 as an elastic portion that stands upright from substantially the center of the upper surface of the connector 42, and a state in which it protrudes forward (in the connection direction of the connector 42) from the upper end of the elastic support piece 46. And an operating portion 49 projecting rearward from the upper end of the elastic supporting piece 46 on the virtual extension line of the locking piece 47 (in the direction in which the connector 42 is detached). 47 has a sliding locking portion 50 protruding in the left-right direction at the distal end.

On the other hand, the locking receiving portion 45 has left and right locking projections 51 erected at substantially the center of the partially cut-out ceiling surface with an interval at which the locking pieces 47 can just enter. An inclined surface 52 is formed on the near side of the locking projection 51, that is, on the connector 42 side as an inclined sliding portion.

In the connector 42 and the connector receiving portion 27 having the lock mechanism having the above-described configuration, the power supply cable 20 connected to the connector 42 is pinched by a finger, and the tip of the connector 42 is inserted into the game control board case 26. The opening 36 faces the fitting opening of the connector receiving portion 27. In this state, the connector 42 is advanced to
Into the fitting opening of the connector receiving portion 27,
When further advanced, the sliding locking portion 50 of the locking portion 44 comes into contact with the inclined surface 52 of the connector receiving portion 27. When the connector 42 is further advanced, the inclined surface 52 displaces the sliding engagement portion 50 upward in the unlocking direction as the connector 42 advances. Subsequently, when the sliding locking portion 50 is sufficiently advanced to the position where the electrical connection is made, the sliding locking portion 50 is lowered by the elasticity of the elastic supporting piece 46 when the sliding locking portion 50 passes the locking projection 51, and the sliding locking portion 50 is locked. It locks on the back surface of the projection 51 and is in a locked state.

As described above, the power supply cable 20 can be inserted without inserting a finger into the insertion opening 36 of the game control board case 26.
The connector 42 can be connected to the connector receiving portion 27 simply by pinching and inserting the connector 42 at the tip end from the insertion opening 36, and the connection state can be locked by the lock mechanism. In this locked state, since the sliding locking portion 50 of the locking piece 47 is locked to the back surface of the locking projection 51, the connector 42 does not come off even when pulled, and maintains the connected state.

The connector 42 can be detached by pushing the operation part 49 downward while pulling it downward. That is, when the operation portion 49 is pressed downward, the elastic support piece 46 is elastically bent, and the front locking piece 47 is inclined in the direction in which the tip rises. Get off the back. Therefore, when the power supply cable 20 is pulled toward the user in this state, the connector 42 can be retracted and removed.

In this embodiment, the unlocking operation of the lock mechanism is performed by the insertion opening 3 of the game control board case 26.
6 is formed in the form of an opening having a size and shape that allows the lock mechanism to be operated only by an operating tool having a cross-sectional area smaller than the cross-sectional area of the connector 42 from the outside. Can not do it. In other words, the power supply cable 20 can be removed by inserting a thin or thin rod-shaped operating tool through the insertion opening 36 and pulling the power supply cable 20 forward while pressing the operating section 49 downward, but it is larger than the cross-sectional area of the connector 42. An operating tool having a sectional area cannot be inserted through the insertion opening 36, and even if an attempt is made to directly insert a finger, the insertion opening 36 is too small to reach the operation section 49. Also, when the operation tool is inserted and the operation unit 49 is pressed downward to release the lock mechanism, a technique is required as compared with the case of operating with a finger,
It takes time, especially in the state where it is attached to the back of the pachinko machine 1 described later, and it takes longer time in combination with the narrow operation space. In other words, the connector 42 located at the back of the insertion opening 36 can be removed by releasing the lock mechanism, but cannot be easily removed, and can be removed only after a long time. Have been.

It should be noted that even if a fingertip is inserted through the insertion opening 36 and reaches the operation unit 49 to be able to release the operation, the operation unit 4 of the connector 42 housed in the game control board case 26 can be operated.
Disassembly of the connector 9, combined with the fact that the space around the hand is narrowed by the power supply unit 3, is far less than that of dismantling the operation part of the conventional connector exposed to the outside. Extreme difficulty. Therefore, even if the operation of the operation unit 49 can be performed by inserting a fingertip through the insertion opening 36, the operation time is longer than in the past, and the possibility of detecting an illegal act increases.

Next, the power supply unit 3 will be described. As shown in FIG. 5, the power supply unit 3 includes a power supply board case 63 including an upper lid member 61 and a bottom lid member 62 having a locking member 60 as a closed state holding unit at an end in the longitudinal direction. In addition to mounting various electronic components for converting alternating current to direct current or converting to a predetermined voltage, a connector receptacle 6 for a power supply for operating these electronic components.
4 houses a power supply board 65 disposed so as to be close to the side wall on the game control unit 2 side.

The connector receiving portion 6 of the power supply board 65
4 has the same basic configuration as the connector receiving portion 27 of the game control board 29, but has a vertical mounting direction. The connector 66 connected to the connector receiving portion 64 also
It has the same configuration as the connector 42 connected to the game control unit 2, and the lock mechanism also has the same configuration.

The bottom cover member 62 is a transparent plastic, shallow box-shaped body having an open top, and has a lower side wall 62b standing from four sides of a bottom surface portion 62a and a portion on the short side bulging out. An elongated locking hole 67 that forms a part of the locking tool 60
A locking claw 69 is formed on the inner surface of the locking hole 67, and a projecting communication portion 70 for supporting the power supply board 65 is protruded inside the bottom surface 62a. Thus, an extension 71 is formed in which a part of the side wall facing the game control unit 2 is higher than other parts.

The top cover member 61 is a transparent plastic box-like body with an open bottom like the bottom cover member 62, and has four side walls 61b vertically extending from the periphery of a ceiling portion 61a having numerous small holes. A locking piece that constitutes one half of the locking tool 60 is protruded from the short side, and an insertion opening 72 through which the power supply cable 20 passes is formed on the side wall facing the game control unit 2 in the mounted state. In this embodiment, the insertion opening 72 is formed in a notch shape, and the extension 71 of the bottom cover member 62 is inserted into the insertion opening 7 in a state where the top cover member 61 is assembled to the bottom cover member 62.
The power supply cable 20 passes through the opening area and is located so that a finger cannot pass therethrough. The locking piece of the locking tool 60 is provided with a locking hole 67 of the bottom lid member 62.
It is formed as a piece of size and shape that just fits into the inside, and when the upper lid member 61 is sufficiently closed at the substantially central portion, the locking claw portion 6 is formed.
9 is provided with a locking hole 73 for fitting. Therefore,
When the power supply board 65 is fixed on the bottom cover member 62 and the connector 66 is connected to the connector receiving portion 64 as shown in FIG. When the locking piece inserted into the hole 67 is slightly bent outward by the inclined surface of the locking claw 69 and is sufficiently pressed, the locking claw 69 is locked in the locking hole 73 to maintain the closed state. .

In this way, the upper lid member 6 is attached to the bottom lid member 62.
When the cover 1 is put on and closed, as shown in FIG.
The insertion opening 72 through which the power supply cable 20 passes is narrowed, and even if the lock mechanism is directed toward the insertion opening 72, it is in a state where a finger cannot be inserted from the outside and operated.

The game control unit 2 having the above configuration
In order to mount the power supply unit 3 and the power supply unit 3 on the pachinko machine 1, first, the power supply unit 3 is mounted on the common base member 21 with the insertion openings 36 and 72 facing each other. When the power supply cable 20 is connected after the game control unit 2 and the power supply unit 3 are mounted on the base member 21,
Since the space between the two units 2 and 3 is short and the two insertion openings 36 and 72 are opposed to each other, the operation is troublesome, and after connecting the power supply cable 20 to the two units 2 and 3 in advance, the base member 21 It is preferable that both units be connected by a power supply cable 20 after one unit is mounted.

The base member 21 is a metal plate-like member slightly larger than the sum of the game control unit 2 and the power supply unit 3, and as shown in FIGS. Each of the mounting members 74 is loosely fitted into a plurality of openings formed in the rear mechanism panel 7, and is detachably mounted on the columnar mounting portion 7 ′ formed integrally with the back mechanism board 7 by the mounting members 74. Further, the base member 21 is provided with a plurality of holes used when being attached to the back side of the game control unit 2 and the power supply unit 3.

The mounting member 74 shown in this embodiment is the same as that shown in FIG.
As shown in FIG. 5, an insertion end 74b is formed at the tip end of a shaft extending from the head 74a, and is a well-known attachment that can be fastened by one-touch simple manual work. That is, this mounting member 7
4 is an insertion end 74 in a mounting hole in the front end surface of the mounting portion 7 '.
b and the head 74a is pushed by hand, the insertion end 74
b expands and locks into the opening edge of the mounting hole to convert it into a state in which it does not easily come off. Conversely, when the head 74a is pulled forward, the insertion end 74b is reduced in diameter, so The end 74b can be easily pulled out from the mounting hole and removed.

The base member 21 is not limited to a metal member, but may be any conductive member, for example, a resin containing carbon or the like.

In order to attach the game control unit 2 in this embodiment to the base member 21, the game control unit 2 is attached to the base member 21 via the conduction auxiliary member 75 in a state where the game control unit 2 is electrically connected to the base member 21.
Specifically, as shown in FIG. 10, inside the communication portion 33, a male screw portion such as a screw 77 inserted from the opening of the GND portion of the game control board 29 by inserting the conduction assisting member 75 from the back side is inserted. The conductive auxiliary member 75 is electrically connected to GND by being tightened and fixed in the female screw hole of the conductive auxiliary member 75, and one end of the conductive auxiliary member 75 is exposed from the outside opening of the communication portion 33.

In this case, the conduction auxiliary member 75 is

a and a hexagonal flange portion 75b formed at one end of the shaft portion 75a and fitted in a hexagonal concave portion 76 formed outside the game control board case 26. This hexagonal recess 7
The 6 and the flange are fitted to function as a detent. In addition,
The depth of the concave portion 76 is set smaller than the thickness of the flange portion 75b.

When the conduction assisting member 75 having such a configuration is inserted into the communicating portion 33 and sufficiently pressed in, the hexagonal flange portion 75b is fitted into the hexagonal concave portion 76, and the hexagonal concave portion is fitted. The inner peripheral surface of the portion 76 abuts against each side of the hexagonal flange portion 75b to prevent free rotation of the conduction assisting member 75. Therefore, if the flange 75b is fitted in the recess 76, the co-rotation of the conduction auxiliary member 75 is prevented when the screw 77 inserted into the opening guide tube 78 of the game control board 29 is tightened. Can be easily tightened.

Since the flange portion 75b is thicker than the depth of the concave portion 76, the male screw 79 inserted into the hole from the back side of the base member 21 with the game control unit 2 pressed against a predetermined position of the base member 21. Is tightened into the female screw hole of the conduction assisting member 75, the end face of the flange 75b protrudes from the raised portion forming the recess 76. Then, the game control unit 2 can be attached to the base member 21 in a state where the protruding portion abuts on the base member 21 and is in a conductive state, whereby the GND of the game control board 29 is connected to the base member 21 via the conductive auxiliary member 75. Is conducted.

On the other hand, the power supply unit 3 is
1, the communication section 70, as in the game control unit 2, is provided in the case 63 of the power supply unit 3.
Since the guide tube portion, the concave portion 76 and the like are formed, the flange portion 7 is formed.
When the conductive auxiliary member 75 having the conductive member 5b is inserted into the communication portion 70 to connect the GND of the power supply board 65 of the power supply unit 3 to the conductive auxiliary member 75, and the power supply unit 3 is attached to the base member 21 in this state. , Conduction auxiliary member 75
Of the power supply unit 3 and the base member 21 can be conducted through the conduction auxiliary member 75.
