In the pachinko gaming machine 1 of the third embodiment in which the game board 5 is housed in such a procedure, it is not necessary to provide a structure for fastening the mounting base 30 to the game board 5 separately from the lock mechanism 90. The number of component parts 5 can be kept low. Moreover, the base side latching | locking part 100 which can be rotated independently of the storage side latching | locking part 76 by simple structure is realizable.

  By the way, the lock mechanism may be able to maintain the lock posture by utilizing the collision of game balls flying in the game area 6. For example, the lock mechanism 70 of the fourth embodiment shown in FIG. 16 has basically the same configuration as that of the second embodiment, but differs in that a buffer member is connected to the locking member 73. More specifically, the game board 5 in the fourth embodiment is a cut-out portion of the partition member 29 disposed in front of the lock mechanism 70 (specifically, the lock mechanism 70 positioned above the game board 5). A ball entry space 115 is formed, and the ball entry space 115 is communicated with the game area 6 so that a game ball can enter. Further, an extension rod 116 is extended forward on the front center side of the panel side locking portion 75, in other words, on the extension line of the connecting shaft 82 until reaching the ball entry space portion 115. A strip-shaped fastening base portion 118 is fastened to the front end of the base plate, and the fastening base portion 118 is set to extend in a vertical direction with the locking member 43 in a locked posture. A rubber cushioning member 119 is fastened to the front side of the fastening base 118 by the fastening member 120, and the side of the cushioning member 119 faces the ball entry space 115. Further, a lid 121 that closes the front side of the board-side recess 47 is provided at the front end of the locked base part 46 to prevent the game ball from entering the board-side recess 47, and the upper part of the lid 121 is The movable stopper 122 protrudes in a detachable state, and the pivot stopper 122 is disposed on the upstream side of the lock pivot direction D on the upper side surface of the buffer member 119 positioned above the extension rod 116 (FIG. 16A). ), The buffer member 119, the extension rod 116, and the locking member 73 are prevented from rotating in the release rotation direction C. When the game board 5 is removed from the game board storage part 18, the rotation stopper 122 can be removed from the lid part 121 and the locking member 43 can be rotated in the release rotation direction C.

  With such a configuration, when a game ball flying in the game area 6 enters the ball entry space 115 and collides with the upper part of the buffer member 119 from the upstream side in the lock rotation direction D, the game ball is buffered. It bounces off at the member 119 and flows down to the game area 6 below. Further, due to the impact received by the buffer member 119 from the game ball, a rotational moment in the lock rotation direction D is generated around the extension rod 116 (that is, on the extension line of the connecting shaft 82) in the buffer member 119 and the extension rod 116. Then, this rotational moment is transmitted from the extension rod 116 to the locking member 73. As a result, the locking member 73 is urged in the direction of rotation in the lock rotation direction D. Therefore, the locking mechanism 70 not only prevents the locking member 73 from rotating in the release rotation direction C by the engagement of the rotation stopper 122 and the buffer member 119, but also temporarily stops the locking member 73. Even if it is rotated in the release rotation direction C, the locking member 73 can be returned to the locked posture by using the flying force of the game ball.

  By the way, in each said embodiment, although the division member 29 and the buffer member 35,119 were arrange | positioned ahead of the board side latching | locking part and the board side recessed part 47, this invention is not limited to this, A part of game board 5 As long as it is a game board constituent member that constitutes, any thing may be arranged.
