Thus, it is preferable to extend from the protruding end of the main body portion 33a. In FIG. 4, the protruding height of the support portion 33 b is set to be larger than the protruding height of the main body portion 33 a, and the front door lock locking piece 33 c is moved from the protruding end of the main body portion 33 a to the back surface of the front door 3. As an example, a configuration of the locking portion 33 is shown in which the extending end surface extends in the right direction toward 3 s so as to be flush with the side surface of the support portion 33 b. As a result, the locking portion 33 has a concave area surrounded by the main body portion 33a, the support portion 33b, and the front door lock locking piece 33c (hereinafter, this area is referred to as a concave area 33s) as the back surface 3s of the front door 3. The structure is on the right side.

  On the other hand, as shown in FIGS. 7 and 8, the front door lock 34 is rotatable to a base member (hereinafter referred to as a front door lock base) 34a provided on the main body frame 2 and the front door lock base 34a. A rotating shaft (referred to as a lock shaft) 34b provided on the movable shaft 34b, a movable member (referred to as a lock claw) 34c supported on the lock shaft 34b, and an elastic force that applies a biasing force to the lock claw 34c. It is a movable structure provided with a member (hereinafter referred to as a lock spring) 34d, and is positioned so that the locking portion 33 of the front door 3 can be locked, and the front side of the main body frame 2 (the back surface 3s of the front door 3). And the vicinity of the lower part of the game board 19.

  The front door lock base 34a includes a plurality of wall members (hereinafter referred to as a base wall) 35 for rotatably supporting the lock shaft 34b, and a lid for covering the lock shaft 34b supported by the base wall 35. And a member (hereinafter referred to as a base lid) 36. In this case, the base wall 35 protrudes forward from the front surface of the main body frame 2 as shown in FIGS. 7 and 8, and the base lid 36 covers a concave region surrounded by the base wall 35. At the same time, it has a flat plate shape having a through hole 36h that can expose the lock shaft 34b to the outside.

  The lock shaft 34b can be accommodated in a concave region surrounded by the base wall 35 of the front door lock base 34a, and has a substantially columnar shape extended with a diameter and a length that can be supported by the base wall 35. And is positioned in the concave region so that its extending direction is parallel to the height direction of the ball game machine, and its upper and lower ends are rotatably supported by the base wall 35 Thus, a part of the through hole 36h of the base lid 36 is exposed.

  By configuring the front door lock base 34a and the lock shaft 34b in such a configuration, the lock shaft 34b has its shaft support position aligned vertically in parallel with the height direction of the ball game machine. The lock claw 34c is fixed to the portion exposed from the through hole 36h of the base lid 36, so that the lock claw 34c is fixed to the front surface of the main body frame 2 (the back surface of the front door 3). It can be moved in the left-right direction toward the surface facing 3s.

  The lock claw 34c includes a fixed portion 37 that is fixed to the lock shaft 34b, and a claw portion 38 that is continuous with the fixed portion 37 and projects forward from the front door lock base 34a. The fixed portion 37 is provided with a stopper 37a for limiting the movable range so that the lock claw 34c does not move more than necessary so as to mesh with the peripheral portion of the through hole 36h of the base lid 36. Yes. Further, the claw portion 38 is provided with a barb 38a whose protruding tip is thicker than the fixed part 37. The barb 38a extends from the protruding tip of the claw part 38 to the protruding base end (with the fixed part 37). It has an inclined structure that gradually increases in thickness toward the direction of (continuous part), and a step 38b is formed by continuing the maximum thickness part and the minimum thickness part of the claw portion 38. .

  7 and 8 show, as an example, the configuration of the lock claw 34c in which the barb 38 has a barb 38a provided on the right side of the front surface of the main body frame 2, the height of the step 38b at that time. (Dimensional difference between the maximum thickness portion and the minimum thickness portion of the return 38a) is such that the front door lock locking piece 33c of the locking portion 33 provided on the front door 3 can be smoothly locked. What is necessary is just to set according to the extension dimension of this front door lock latching piece 33c.

  In this case, the size of the lock claw 34 c (claw portion 38) is set to be slightly smaller than the concave region 33 s of the locking portion 33. That is, by setting the relative sizes of the locking portion 33 and the front door lock 34 as described above, when the locking portion 33 is locked to the front door lock 34, the lock claw 34c (claw portion) 38) can be accommodated in the concave region 33s, and the locking portion 33 and the front door lock 34 can be smoothly locked.

  As shown in FIG. 7, the lock spring 34d has one end (the left end in the figure) fixed to a fixed shaft 44 protruding from the front surface of the main body frame 2, and the other end (the right end). It is fixed to the fixing portion 37 of the lock claw 34c. In this state, the lock spring 34d has a biasing force from the right to the left toward the front surface of the main body frame 2, and the biasing force is always applied to the fixing portion 37 of the lock claw 34c. In other words, the lock claw 34c can always rotate rightward toward the front surface of the main body frame 2 around the lock shaft 34b by the biasing force applied from the lock spring 34d. By retracting from the stopper 37a of 37 to the base lid 36, the posture is kept stationary.

  According to such a configuration, when the front door 3 that is opened with respect to the main body frame 2 is closed, the locking portion 33 causes the front door lock locking piece 33 c to be connected to the lock claw 34 c of the front door lock 34. With the claw portion 38 in contact with the claw portion 38, the lock claw 34 c is rotated counterclockwise around the lock shaft 34 b toward the front surface of the main body frame 2 against the urging force, Along the rear side (backward with respect to the main body frame 2). When the front door lock locking piece 33c further moves rearward and reaches the level difference 38b, the position of the front door lock locking piece 33c relative to the claw portion 38 moves from the right to the left toward the front surface of the main body frame 2. The front door lock locking piece 33c is engaged with the step 38b.

  As a result, the lock claw 34c that has been rotated to the left around the lock shaft 34b against the biasing force again moves the stopper 37a around the lock shaft 34b by the biasing force to the through hole 36h of the base lid 36. The lock claw 34c is stopped in this state by being rotated rightward until it is engaged with the peripheral edge. Accordingly, the position of the front door lock locking piece 33c is fixed with respect to the barb 38a of the claw portion 38, whereby the locking portion 33 can be stably locked to the front door lock 34.

  The extending direction of the front door lock locking piece 33c of the locking portion 33 with respect to the back surface 3s of the front door 3 (in other words, the formation direction of the concave region 33s) and the lock claw 34c (claw portion 38). It is possible to lock the locking portion 33 and the front door lock 34 by setting the disposing direction 38a to the front surface of the main body frame 2 to be the same. Therefore, such a direction is not limited to the right direction toward the back surface 3s of the front door 3 and the front surface of the main body frame 2 as in the present embodiment, and may be any of the left direction and the vertical direction, for example. . At that time, if the lock spring 34d is disposed by setting the direction of the urging force that acts on the lock claw 34c so that the lock portion 33 and the front door lock 34 can be locked stably. Good.

Here, in the present embodiment, when the locking portion 33 is locked with the front door lock 34 as described above, it is not necessary to add an artificial locking operation for that purpose, and the front door 3 can be attached to the main body frame 2. Simultaneously with the closing of the door, the position of the front door lock engagement piece 33c can be automatically fixed to the return 38a of the stationary lock claw 34c (claw portion 38). It can be locked.
Thus, in this embodiment, when the front door 3 is closed with respect to the main body frame 2, the locking portion 33 can be automatically locked to the front door lock 34. The locking of the portion 33 and the front door lock 34 is artificially performed by a locking control means.

  As shown in FIGS. 5 to 13, the locking control means includes a movable member (lock movable piece 25 (specifically, the lower lock movable piece 25 c) that moves in conjunction with the unlocking of the front door 3 by the locking device 24. )), An interlocking lever 39 that moves in conjunction with the movement of the lower lock movable piece 25c, and a connecting member 40 that connects the interlocking lever 39 and the front door lock 34. In this case, the interlocking lever 39 forms a rod body, and the base end portion of the interlocking lever 39 is connected to a member 41 (hereinafter referred to as an interlocking lever bearing) that interlocks with the interlocking lever 39, and the connecting member 40 is connected via the interlocking lever bearing 41. And is disposed in the main body frame 2 in a state in which a portion up to the tip end portion is in contact with the lower lock movable piece 25c.

  In the configuration shown in FIGS. 9 and 10, the interlock lever bearing 41 has a substantially semicircular flat plate shape as an example, and rotates around a predetermined axis 43 (FIGS. 5, 6, and 13) in conjunction with the interlock lever 39. It has a movable structure. In this case, the interlocking lever bearing 41 is connected to the base end portion of the interlocking lever 39 at a string-shaped portion, and the other end portion of the connection member 40 having one end portion connected to the front door lock 34 at the arc-shaped portion. Are connected. Thus, the interlocking lever 39 and the connection member 40 are connected via the interlocking lever bearing 41, and the interlocking lever bearing 41 and the front door lock 34 are connected via the connection member 40. . That is, the interlocking lever 39 and the front door lock 34 are connected by the connecting member 40 through the interlocking lever bearing 41. The interlocking lever 39 and the front door lock 34 may be connected by directly connecting the interlocking lever 39 and the connecting member 40 without providing the interlocking lever bearing 41.

As the connecting member 40, any member having an arbitrary line shape or bar shape can be selected and applied as long as the interlocking lever 39 and the front door lock 34 can be connected. As an example, a case where a piano wire is applied is assumed.
As shown in FIG. 7, the connecting member (piano wire) 40 is provided with a hook 40k at one end connected to the front door lock 34, and the hook 40k is hooked on the fixing portion 37 of the lock claw 34c. The front door lock 34 is connected. On the other hand, the other end of the connecting member (piano wire) 40 is connected to the interlocking lever bearing 41 by a fastening member (for example, a bolt and a nut) as shown in FIGS.

The hook 40k is a hook member that is separate from the connecting member (piano wire) 40, and the hook member is attached to one end of the connecting member (piano wire) 40 by caulking, bonding, or the like. The member (piano wire) 40 may be provided, or the hook 40k may be provided integrally with the connecting member (piano wire) 40 by bending or bending the one end. When the hook 40k has a separate configuration, when the connecting member (piano wire) 40 is laid, all of them are attached to or inserted into a guide member 42 (FIGS. 9 and 10) and a through-hole 37h (FIG. 11) described later. However, when the hook 40k is integrated, there is no need to procure a hook member separately, the number of parts can be reduced, and the hook member need not be attached. The work process can be reduced.
Moreover, the connection method of the connection member (piano wire) 40, the front door lock 34, and the interlocking lever bearing 41 is not limited to the method described above, and may be connected by various known methods.

  In this case, the main body frame 2 is provided with a connecting member (piano wire) 40 and a plurality of members (hereinafter referred to as guide members) 42 for guiding the connecting member (piano wires) 40 (in FIG. 9 and FIG. 10, four pieces). ) Is provided. By providing a plurality of guide members 42 in this way, the connecting member (piano wire) 40 can be connected between the interlocking lever 39 and the front door lock 34 without loosening or bending, and the connecting member (piano wire). Even if a special space for laying 40 is not secured, the connecting member (piano wire) 40 can be laid by effectively utilizing the clearance between the existing members of the main body frame 2.

  Further, the base wall 35 of the front door lock base 34a is cut out at a portion that contacts the laying path of the connecting member (piano wire) 40 as shown in FIGS. 7 and 8, and is locked as shown in FIG. A through-hole 37 h for inserting a connecting member (piano wire) 40 is drilled in the fixing portion 37 of the claw 34 c in the left-right direction with respect to the front surface of the main body frame 2.

  Thus, in this embodiment, the connection member (piano wire) 40 is connected with the hook 40k on the left side toward the front surface of the main body frame 2 of the fixing portion 37 of the lock claw 34c. As a result, by applying a tensile load to the connecting member (piano wire) 40, the lock claw 34c of the front door lock 34 is directed to the front surface of the main body frame 2 around the lock shaft 34b against the urging force of the lock spring 34d. Can be turned leftward.

  When the lock claw 34c is rotated leftward around the lock shaft 34b, the lock claw 34c is fixed to the lock portion 33 locked to the front door lock 34, specifically, the claw portion 38 of the lock claw 34c. The position of the front door lock engaging piece 33c is shifted from the left direction toward the right direction along the step 38b toward the front surface of the main body frame 2. When a tensile load is continuously applied to the connecting member (piano wire) 40 and the lock claw 34c is further rotated leftward around the lock shaft 34b, the front door lock locking piece 33c is engaged. It deviates from the step 38b. As a result, the position of the front door lock locking piece 33c is released with respect to the return 38a of the claw portion 38, and the front door 3 is opened with respect to the main body frame 2 in this state, so that the locking portion 33 and the front The engagement with the door lock 34 can be released.

As described above, the ball game machine according to the present embodiment is provided with the locking device 24 for opening and closing the front door 3, and a keyhole for opening the front door 3 with respect to the main body frame 2. When the key (not shown) inserted into the key 28 is rotated from the lock position to the lock position, the locking movable piece main body 29 is pushed down.
That is, at this time, the lower movable movable piece 25c formed on the movable movable piece main body 29 is pushed down together with the movable movable piece main body 29.

  Since the interlocking lever 39 is in contact with the lower lock movable piece 25c and moves in conjunction with the movement of the lower lock movable piece 25c, when the lower lock movable piece 25c is pushed down, In conjunction with this, the tip is pushed down so as to move downward toward the front surface of the main body frame 2. The interlocking lever 39 is connected to the interlocking lever bearing 41, and the interlocking lever bearing 41 is rotated around the shaft 43 in conjunction with the interlocking lever 39 when the interlocking lever 39 is pushed down. In the present embodiment, the interlocking lever bearing 41 is rotated clockwise as shown in FIGS. When the interlocking lever bearing 41 is rotated clockwise, the turning force acts on the connection member (piano wire) 40 connected to the interlocking lever bearing 41 as a tensile load.

  Therefore, when the key (not shown) inserted into the key hole 28 of the locking device 24 (operation unit 26) is rotated from the lock position to the lock position, that is, the front door 3 is unlocked, and the main body frame 2 When the door is opened, the locking of the locking portion 33 and the front door lock 34 can be released in conjunction with the operation of the key.

  Accordingly, it is not necessary to perform an operation for unlocking the locking portion 33 and the front door lock 34 separately from the key operation for unlocking the front door 3, and the front door 3 is moved by the locking device 24. When unlocked, locking can be released in synchronization with this. That is, the locking control means (for example, the lower lock movable piece 25c, the interlocking lever 39, the connecting member (piano wire) 40, and the interlocking lever bearing) with a simple structure is used to cancel the locking between the locking portion 33 and the front door lock 34. 41), and the unlocking can be performed easily and very smoothly.

  When the tensile load applied to the connection member (piano wire) 40 is released after the engagement between the engagement portion 33 and the front door lock 34 is released, the lock claw 34c is locked by the urging force of the lock spring 34d. The shaft 34b is rotated rightward toward the front surface of the main body frame 2 to return to the state before the locking between the locking portion 33 and the front door lock 34 is released. Further, at that time, the interlocking lever bearing 41 is rotated counterclockwise via the connecting member (piano wire) 40, the interlocking lever 39 is pushed up, and the lower lock movable piece 25c is also pushed up, and these are unlocked. Return to state.

  As described above, according to the ball game machine according to the present embodiment, during the game of the player, the front door 3 is not only locked to the main body frame 2 but also the locking portion 33 of the front door 3. Is engaged with the front door lock 34 of the main body frame 2, and the position of the front door 3 with respect to the main body frame 2 can be fixed. Therefore, the space between the game board 19 and the glass plate 4 cannot be expanded, and an illegal act performed using a space intentionally generated between them can be surely prevented.

In the above-described embodiment, when the front door 3 is closed with respect to the main body frame 2, the locking portion 33 is automatically locked to the front door lock 34. The front door lock 34 may be interlocked with a key operation for closing the front door 3.
In this case, for example, when a key (not shown) inserted into the key hole 28 of the locking device 24 (operation unit 26) is rotated from the unlocked position to the locked position, that is, the front door 3 is locked, When the main body frame 2 is closed (when the door cannot be opened), the interlocking lever 39 is pushed up in conjunction with the pushed-up lower lock movable piece 25c, and the interlocking lever 39 is interlocked. Thus, the interlocking lever bearing 41 may be configured to rotate counterclockwise.

That is, when the interlocking lever bearing 41 is rotated counterclockwise, the turning force acts as a force for loosening the tensile load applied to the connecting member (piano wire) 40 connected to the interlocking lever bearing 41. Can be made. As a result, the lock claw 34c can be rotated to the right and stopped until the stopper 37a meshes with the peripheral edge of the through hole 36h of the base lid 36 around the lock shaft 34b by the urging force of the lock spring 34d. At this time, the front door lock locking piece 33c is engaged with the step 38b of the claw portion 38, and the position of the front door lock locking piece 33c is fixed to the return 38a of the claw portion 38. 33 can be locked to the front door lock 34.
Thus, the locking of the locking portion 33 and the front door lock 34 can be performed together with the unlocking by the locking control means having the simple structure described above.
