On the other hand, if the power supply device is moved upward and pulled out of the concave portion, the power supply device is released from the concave portion, so that only the concave portion with a simple structure fitted to the lower end portion of the power supply device is used. A guide part can be comprised.
Here, the position where the bottom surface reaches the bottom of the concave portion is defined as a fixing position of the power supply device, and the power supply device placed at the fixed position is pressed against the concave portion so that the power supply device is not pulled out from the concave portion. Therefore, when the internal device close to the power supply device also serves as the movement prevention means, the internal device is also used as the movement prevention means only by providing a contact portion for pressing the power supply device. Therefore, the modification of the internal device is minimally required, and the internal device can be easily used as the movement preventing means.

(Effect of feature point 3 )
According to the feature point 3 , a pair of hopper guide rails that employ a hopper unit that can be juxtaposed with the power supply device on the bottom plate of the housing as the movement preventing means, and that have grooves opened to face each other. Since the hopper locking collar portion of the hopper unit is locked inside the groove of the hopper guide rail and the hopper unit slides along the hopper guide rail. The hopper unit installed on the body can move in the horizontal direction along the hopper guide rail, but cannot move in the vertical direction.
In addition, when the protrusion is provided on the hopper unit, if the protrusion is provided at a height level corresponding to the upper surface of the power supply device, the protrusion of the hopper unit can be obtained by horizontally moving the hopper unit and arranging it next to the power supply device. Since the protrusion is pressed down on the upper surface of the power supply device, the power supply device cannot be removed from the concave portion.

On the other hand, when the claw of the locking claw 53D is released from the peripheral edge of the hole to be locked and the locking state is released, the protective cover portion 54 can move to the fully opened position where the operation panel portion 53 is released. .

(Effect of 1st Embodiment)
According to the first embodiment as described above, the following effects can be obtained.
That is, a socket 31 having a concave portion 33 for fitting the lower end portion of the power supply device 9 is provided on the upper surface of the bottom plate 42 of the housing 2, and the position where the bottom surface of the power supply device 9 reaches the bottom portion of the concave portion 33 is By setting the position where the bottom surface of the power supply device 9 is at the same height level as the top portion of the rising portion 32 which is the side wall of the concave portion 33 as the fixed position of the device 9, Since the socket 31 provided with the concave portion 33 forms the movement guide means including the guide portion for guiding the power supply device 9 between the fixed position and the open position, the bottom surface is the bottom of the concave portion 33. When the power supply device 9 is disposed at a fixed position that reaches the position, the power supply device 9 cannot be moved in the horizontal direction, while the power supply device 9 is moved upward from the concave portion 33 to open the lower end portion of the power supply device 9. When the position is exceeded, the power supply 9 is recessed 33 It is possible to move freely.
Then, a protrusion 22 is provided on the hopper unit 20 that is an internal device close to the power supply device 9, and the protrusion 22 fixes the power supply device 9 in a fixed position when the protrusion 22 is in contact with the upper surface of the power supply device 9. Therefore, if the power supply device 9 is arranged at a fixed position and then the hopper unit 20 is installed at a predetermined position, the power supply device 9 cannot be moved. The device 9 can be fixed.
In other words, since the power supply device 9 can be fixed at the fixed position by contacting the protrusion 22 of the hopper unit 20, the power supply device 9 is fixed without using a connector such as a screw. As a result, the power supply device 9 can be easily attached.
On the other hand, if the hopper unit 20 is removed from the housing 2, the protrusion 22 of the hopper unit 20 moves to a position that does not interfere with the movement of the power supply device 9, so the hopper unit 20 is removed from the housing 2. If this is the case, the power supply device 9 can be easily removed from the concave portion of the socket, whereby the power supply device 9 can be easily detached from the housing 2 and the power supply device 9 can be easily removed. .

Here, the hopper unit 20 seems to be suspicious by anyone if the player removes it from the housing 2, but there is no suspicious point even if a stadium staff removes it from the housing 2, According to the staff, it can be easily detached from the housing 2.
And if the hopper unit 20 is removed, the power supply device 9 can also be easily removed from the housing 2, so that the power supply device 9 can be easily removed from the housing 2 according to the staff of the game hall, Therefore, the installation work of the power supply device 9 can be facilitated.
On the other hand, since the player's act of removing the hopper unit 20 from the housing 2 is conspicuous, the possibility of detaching the hopper unit 20 from the housing 2 is small, and the possibility of removing the power supply device 9 from the housing 2 is also small. As a result, fraud can be prevented.
In the unlikely event that an unauthorized act of removing the hopper unit 20 from the housing 2 is performed, the unauthorized act is prominent, and is immediately detected by an attendant at the game hall. It is possible to prevent the act from being completed, and from this point, it is possible to prevent fraud.
As described above, the power supply device 9 can be easily detached from the housing 2 and the power supply device 9 can be easily attached to the housing 2 by an appropriate operation by a staff member. In operation, the power supply device 9 cannot be removed from the housing 2, so that even if the power supply device 9 can be easily attached and removed, fraud can be prevented.

In addition, a socket 31 having a concave portion 33 for fitting the lower end portion of the power supply device 9 is provided. The power supply device 9 is inserted into the concave portion 33 of the socket 31 from above, and the bottom surface of the power supply device 9 is placed at the bottom of the concave portion 33. If it reaches, the power supply device 9 cannot move downward any more and cannot move in the horizontal direction. On the other hand, if it is pulled out from the concave portion 33, the power supply device 9 is released from the concave portion 33, Free movement is possible.
For this reason, the position where the bottom surface of the power supply device 9 reaches the bottom of the concave portion 33 can be set as a fixed position, and the height level at which the bottom surface of the power supply device 9 reaches the top portion of the concave portion 33 is set as the open position. Therefore, the guide part for guiding the power supply device 9 between the fixed position and the open position can be formed only by the concave part 33 having a simple structure, and the moving guide configured with the guide part can be formed. Means can be easily realized.
Here, when viewed from the front, the hopper locking collars 23, 24 are provided on both sides of the bottom surface of the hopper unit 20, and a pair of hopper guide rails 25, 26 having grooves 27 opened so as to face each other are provided in the housing 2. The hopper locking rails 23 and 24 of the hopper unit 20 are locked in the grooves 27 of the hopper guide rails 25 and 26, and the hopper unit 20 is moved to the hopper guide rails 25 and 26. Therefore, the hopper unit 20 can move along the hopper guide rails 25 and 26, but cannot move in the vertical direction.
Therefore, if the hopper unit 20 is moved horizontally along the hopper guide rails 25 and 26 and arranged next to the power supply device 9, the protrusion 22 of the hopper unit 20 is arranged immediately above the power supply device 9. Thus, the protrusion 22 presses the upper surface of the power supply device 9 to prevent the movement of the power supply device 9, so that the hopper unit 20 can prevent the movement without significantly changing the structure of the hopper unit 20 or the like. Can also be used.
For this reason, when the hopper unit 20 is also used as the movement blocking means, modification and design change to the hopper unit 20 are minimally required, so that the hopper unit 20 can be easily used as the movement blocking means. .
