When the locking member 21 is lifted, the operating member 25 shown in FIG. 3A is operated upward, so that the locking member 21 is locked together with the mounting member 23 that can be moved up and down by the long hole 36. The member 21 is lifted upward.

  As shown in FIG. 6 (d), when the lock is released, the state in which the opening side of the concave portion 33 is closed by the leaf spring 22 is maintained. Even if the main body 11 is inclined, the concave portion 33 can be pulled out smoothly and straight without being caught by the locking hole 14. The leaf spring 22 preferably covers at least the width of the bottom plate portion 38 to be the same as the width of the recess 33 in order to cover the entire recess 33. In addition, the folded portion 39 has a sufficient length so that the folded portion 39 is not caught by the holder 12 when the leaf spring 22 is pushed backward.

  According to the present invention, when pulling out the machine body 11, the bottom plate portion 38 of the leaf spring 22 closes the recessed portion 33 and the unlocked state is maintained, so there is no need to put a hand in the unlocking direction, It can be easily pulled out with one hand. Therefore, it is not necessary to open the adjacent game table. Furthermore, if the lock is released, it is possible to close the gaming table and pull it out from the outside. Thereby, since it takes only a short time to open the game table and expose the inside of the game table, for example, a third party such as a player can prevent acts such as attaching an unauthorized member from the back of the game table.

  Moreover, the present invention has a very simple configuration, can be implemented at low cost, and can be easily replaced and maintained.
