  As shown in FIG. 1, the ball game machine 1 has a game board 3 fitted in an outer frame 2 installed in a game facility, and effects information such as numbers and symbols relating to the game are displayed behind the game board 3. The display device (not shown) is arranged, and is stored in the ball storage tray 5 provided on the front surface by rotating the operation handle 4 provided on the lower right portion of the front surface in the clockwise direction. A predetermined game can be performed by driving a game ball from a launching device (not shown) into a substantially circular game area 31 provided on the surface of the game board 3.

  On the surface of the game board 3, a circular (including elliptical) game area 31 surrounded by the guide rails 6 and 7 is provided, and the game balls launched from the launching device are guided by the guide rails 6 and 7. Then, the game area 31 is driven.

  The game area 31 includes a number of game nails (not shown) that change the flow direction of game balls that are driven into the game area 31 as main components, and a perspective display that allows visual display of the effect information displayed on the display device. The window 8, the decorative member 9 for decorating the periphery of the transparent display window 8, the through chucker 10 through which the game ball can pass, the symbol start port 11 through which the game ball can win, the first state disadvantageous for the player (the game ball wins the game) A large winning opening 12 or the like that can be changed between an impossible closed state) and a second state advantageous to the player (open state in which game balls can be won) is arranged. In addition, at the bottom of the game area 31, an out port 13 is provided for discharging the game balls that have been driven into the game area 31 to the back side of the game board 3.

  When a game ball that has been driven into the game area 31 wins the symbol start port 11, the presentation information displayed on the display device is variably displayed based on a predetermined probability, and after a predetermined time has elapsed. Stop and confirm. And, when the combination of the numbers, symbols, etc. that are confirmed and displayed is a predetermined display mode, for example, when the same numbers and symbols are aligned, a big hit state is generated and the big prize opening 12 is in the first state. To a second state to give a predetermined game value to the player.

  When a game ball that has been driven into the game area 31 passes through the through chucker 10, a lottery such as generating a right for a big hit or a small hit chance is performed in the gaming machine 1 based on a predetermined probability. The control unit provided in

  The through chucker 10 has a synthetic resin holding member 14 attached to the front surface of a mounting hole 32 penetrating in the front-rear direction provided in the game board 3, and is held in the holding member 14 to magnetically pass the game ball. And a sensor 15 for detecting by optical or electrical means.

  The holding member 14 protrudes forward from the front surface of the base portion 141 and is fixed to the surface of the game board 3 with a screw 16 that forms a fastening member, and the front half of the sensor 15 can be inserted from the rear. The game board 3 protrudes rearward from the back surface of the base part 141 and the surrounding part 142 whose upper and lower surfaces are opened so that the game ball can pass from the upper side to the lower side. The left and right holding portions 143 and 144 that can hold the left and right sides of the sensor 15 are integrally formed. The left and right holding portions may be reversed left and right.

  The left holding portion 143 is a vertical piece for holding the left side surface 15a of the sensor 15 by holding the left side surface 15a including the lower corner portions 15b and 15c from the upper and lower sides and the left side on the left side surface 15a side of the rear half of the sensor 15. A vertical horizon portion 143b, a horizontal horizontal upper portion 143b and a lower horizontal piece 143c that are bent at a right angle from the upper and lower ends of the vertical piece 143a to the inside, and suppress a part of the upper and lower sides of the sensor 15. It has a substantially U-shaped vertical cross section (in particular, see FIG. 8) and is formed so as not to be elastically deformed substantially in the left-right and up-down directions. The length of the left holding portion 143 in the front-rear direction is set so that the rear end protrudes rearward from the rear end surface of the sensor 15.

  The right holding portion 144 has an almost inverted L shape that suppresses the upper corner portion 15e on the right side surface 15d side of the rear half of the sensor 15, and substantially has an upper piece portion 144a that is not elastically deformed in the left-right and up-down directions. 2 in the front-rear direction between the lower piece 144b, which is substantially L-shaped to suppress the portion 15f, and which is substantially not elastically deformed in the left-right and up-down directions, and between the upper piece 144a and the lower piece 144b and whose rear end is open. An elastic piece having a slit 144c, 144c, and a flange 144d between the slits 144c, 144c, which is elastically deformable in the left-right direction and that can be engaged with a part of the rear end surface of the sensor 15 at the rear end. 144e is integrally formed. With this configuration, that is, by providing the slits 144c and 144c between the elastic piece portion 144e and the respective piece portions 144a and 144b, the elastic piece portion 144e has its own elasticity when the sensor 15 is mounted in the holding member 14. The deformation can be flexibly and elastically deformed without affecting the lower piece portions 144a and 144b. In addition, the upper and lower pieces 144a and 144b are not substantially elastically deformed even though the elastic piece 144e can be softly elastically deformed. be able to.

  The sensor 15 has a rectangular shape in plan view, and a game ball passing gate 151 is provided in a substantially front half inserted and held in the surrounding portion 142 of the holding member 14, and the game ball driven into the game area 31. Passes the game ball passage gate 151 to detect the passage of the game ball.

  The sensor 15 is attached to the holding member 14 by inserting the sensor 15 from the rear side between the left holding portion 143 and the right holding portion 144 of the holding member 14 and pushing it forward while slightly bending the elastic piece portion 144e outward. As a result, substantially the front half of the sensor 15 enters the surrounding portion 142 of the holding member 14, and the flange portion 144 d of the elastic piece portion 144 e engages with a part of the rear end surface of the sensor 15. In this case, since the flange portion 144d is provided only on the elastic piece portion 144e of the right holding portion 144, the sensor 15 can be easily inserted into the holding member 14 and attached.

  In a state where the sensor 15 is held by the holding member 14, the elastic piece portion 144 e of the holding member 14 is engaged with a part of the rear end surface of the sensor 15, so that the backward movement of the sensor 15 is suppressed. The sensor 15 does not fall off the holding member 14. In addition, the left and right portions of the left and right holding parts 143 and 144b of the holding member 14 that are not elastically deformed substantially include upper and lower pieces 144a and 144b including the respective corners 15b, 15c, 15e, and 15f of the sensor 15. Even if the elastic piece portion 15e can be elastically deformed flexibly so as to hold the both side surfaces 15a and 15d side, the sensor 15 is held by reliably preventing rattling of the sensor 15 in the left-right direction. The member 14 can be securely held.

  Furthermore, the left holding portion 143 of the holding member 14 has a length that protrudes rearward from the rear end surface of the sensor 15, so that the rear left corner portion 15 g of the sensor 15 particularly has a structure as shown in FIG. Since the sensor 15 can come into contact with the inner surface of the left holding part 143, the sensor 15 rattles in the direction in which the sensor 15 is easily detached from the collar part 144d. Specifically, as shown by an arrow in FIG. It is possible to effectively suppress the wobbling of the tilt that is biased to the left.
