【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, a schematic configuration of the entire pachinko machine will be described based on FIG. 8 (an exploded perspective view of the pachinko machine). The machine frame 11 of the pachinko machine is formed of plastic such as ABS resin. A pachinko ball launching device 12 and the like are attached to the lower portion of the machine casing 11, and a glass door 14 that covers the front face of the game board 13 is opened and closed via a hinge (not shown) on the front face of the machine casing 11. Mounted as possible.
[0011]
On the other hand, on the back surface of the machine casing 11, a back part mounting portion 15 is integrally formed. The back part mounting portion 15 is formed with an opening 18 through which the center accessory unit 16 and the collecting plate 17 mounted on the back surface of the game board 13 project rearward. Further, the back part mounting portion 15 is formed in a shape that wraps around the outer peripheral portion of the back surface of the game board 13 so as to function as a positioning stopper (mounting recess of the game board 13) at the rear of the game board 13.
[0012]
The back parts attached to the back side of the back part mounting portion 15 are separately assembled into three units, a prize ball supply unit 19, a prize ball discharge unit 20, and a lower unit 21. In this embodiment, the prize ball replenishing unit 19 has a configuration in which a tank 22 for storing a prize ball and a tank rail 23 serving as a passage of a prize ball flowing out of the tank 22 are unitized. On the other hand, the prize ball discharge unit 20 discharges a predetermined number of prize balls supplied from the tank rail 23 each time a proof ball is detected by a proof ball detection unit (not shown) described later. Further, the lower unit 21 includes a safe ball gutter portion (not shown) for collecting safe balls entering a winning opening (not shown), a proof ball detecting portion (not shown) for detecting a proof ball, and a prize ball discharging unit. The unit has a prize ball vertical distribution unit (not shown) for distributing the prize ball discharged from the upper and lower ball trays (not shown) into a unit.
[0013]
Each of these units 19 to 21 is attached by engagement to an engagement receiving portion 24 formed on the back component attachment portion 15, and this engagement state is locked by a lock member 28. The lock member 28 is attached by a spring (not shown) so that it can be displaced in the front-rear direction, and the locked state can be released by pushing the lock member 28 in.
[0014]
On the other hand, the game board 13 is detachably attached to the machine casing 11 from the front side as follows. First, a method of supporting the left side (one side) of the game board 13 will be described with reference to FIGS. At the center of the left side (one side) of the machine frame 11, a stopper metal plate 41, which is a swing type fitting member, can swing in the front-rear direction via a vertically extending shaft pin 42 (see FIGS. 3 and 4) ( (Rotatable). The stopper plate 41 has a rotation restricting portion 41a for restricting a rotation angle in a rearward direction (counterclockwise direction in FIG. 3), and a pressing piece portion 41b for pressing the center of the left side of the game board 13 from the front side. Are integrally formed. A square block-shaped positioning base 43 for positioning the game board 13 in the up-down direction is attached to the pressing piece 41b with screws 44 (see FIG. 4).
[0015]
Further, through holes 45 (see FIG. 3) are formed at two upper and lower portions of the holding piece portion 41b, and bosses 46 formed integrally with the positioning table 43 are inserted into the through holes 45. A spring 47 and a sliding member 48 are inserted through the boss 46, and the sliding member 48 is prevented from being pulled out by a washer 49 screwed to the boss 46. The sliding member 48 comes into contact with the machine frame 11 and plays a role of urging the stopper plate 41 rearward (counterclockwise in FIG. 3) by the elastic force of the spring 47.
[0016]
A fitting recess 50 (see FIG. 2) is formed on the left side of the game board 13 in correspondence with the positioning table 43 described above. Direction positioning is performed. Further, in this embodiment, in order to ensure the vertical positioning of the game board 13, the positioning protrusions 51 (see FIG. 1) extending horizontally in two places above and below the left side (one side) of the machine casing 11. 1) is formed, and by fitting the fitting concave portion 52 formed on the back surface of the game board 13 into the positioning convex portion 51, the game board 13 is vertically positioned. Therefore, in this embodiment, the vertical positioning of the game board 13 is performed by three "positioning portions" of the two positioning projections 51 and the positioning table 43.
[0017]
On the other hand, the rearward positioning of the game board 13 is performed by the back part mounting portion 15 as described above, and in this state, the left side of the game board 13 is pressed from the front side by the pressing piece 41b of the stopper plate 41. The left side of the game board 13 is sandwiched and fixed between the holding piece portion 41b and the back component mounting portion 15.
[0018]
Next, a method of fixing the right side (other side) of the game board 13 will be described. In this embodiment, as shown in FIG. 1, two upper and lower portions on the right side of the game board 13 are pressed and fixed to the back component mounting portion 15 side with a stopper 55. As shown in FIGS. 5 to 7, the stopper 55 is supported by a shaft pin 56 extending in the vertical direction so as to be rotatable in the front-rear direction and slidable in the vertical direction. The stopper 55 is urged upward to the non-engagement position [the position in FIG. 5B] by the axial repulsive force of the torsion coil spring 57 (urging means) mounted below the shaft pin 56. At the same time, the torsional repulsive force of the torsion coil spring 57 urges the game board 13 to turn to a retreat position (a position indicated by a two-dot chain line in FIG. 7) which does not hinder the mounting and dismounting of the game board 13. In addition, a buffer spring 58 for buffering an impact when the stopper 55 returns to the disengaged position is mounted on the upper portion of the shaft pin 56.
[0019]
In this embodiment, as shown in FIG. 5, two engagement holes 59 are formed in the upper and lower portions of the stopper 55 in order to engage and fix the stopper 55 in a state where the stopper 55 is pressed against the game board 13. An engagement pin 60 (engagement member) is provided on the right side of the machine frame 11 corresponding to each engagement hole 59. As shown in FIGS. 6 and 7, each engagement pin 60 is slidably inserted in the front and rear direction through an insertion hole 62 of a positioning boss 61 formed on the right side of the machine frame 11, and attached to the rear side. The spring 63 is biased so as to be pulled backward. The retracting amount of each of the engagement pins 60 is limited by a retaining member 64 screwed to the back surface of the positioning boss 61. A fitting groove 65 is formed in the outer peripheral portion of the front end of each engaging pin 60, and the stopper 55 is engaged with the peripheral edge of the engaging hole 59 of the stopper 55 by fitting into the fitting groove 65. 60 is engaged and fixed. At this engagement fixed position, as shown in FIG. 7, the stopper 55 presses the right side of the game board 13 from the front side, so that the right side of the game board 13 is located between the stopper 55 and the back part mounting portion 15. To fix it.
[0020]
In order to release this engaged state, as shown in FIG. 5, a wide engagement release hole 66 is continuously formed in the stopper 55 from the engagement hole 59 toward the lower side. The engagement pin 60 is disengaged from the engagement hole 59 by sliding the 55 from the engagement fixed position (the position shown in FIG. 5A) to the non-engagement position (the position shown in FIG. 5B). The stopper 55 is automatically rotated to the retracted position (the position shown by the two-dot chain line in FIG. 7) by the torsion repulsive force of the torsion coil spring 57 at the same time when the engagement is released by being released into the hole 66. ing. In addition, a knob 67 is integrally formed at the upper end of the stopper 55 so that an operator can grip the knob 67 and slide the stopper 55 in the vertical direction.
[0021]
As shown in FIG. 2, fitting recesses 68 are formed at upper and lower portions of the right side of the game board 13 so as to correspond to the positioning boss portions 61 on the right side of the machine casing 11. By fitting into the part 61, the right side of the game board 13 is also positioned in the vertical direction similarly to the left side.
[0022]
Next, a procedure for attaching the game board 13 to the machine casing 11 from the front side will be described. First, the fitting recesses 50 and 52 on the left side of the game board 13 are fitted into the positioning base 43 and the positioning projections 51 to position the game board 13 in the up-down direction, and as shown in FIG. The left side of the game board 13 is inserted into the inside (rear side) of the holding piece 41b of the stopper plate 41. As a result, the game board 13 is supported so as to be swingable in the front-rear direction with the stopper plate 41 as a fulcrum. Thereafter, when the game board 13 is swung rearward with the stop metal plate 41 as a fulcrum, as shown in FIG. 3C, the back surface of the game board 13 abuts against the back part mounting portion 15 and the game board 13 The rearward positioning is performed. At this time, the stopper 55 on the right side of the machine casing 11 is held at the retracted position (the position indicated by the two-dot chain line in FIG. 7) by the torsional repulsive force of the torsion coil spring 57, so that the stopper 55 becomes an obstacle. There is no.
[0023]
As described above, after the back surface of the game board 13 is brought into contact with the back part mounting portion 15, the knob 67 of the stopper 55 is pinched and the stopper 55 is rotated to the front side of the game board 13. Then, the stopper 55 is brought into contact with the front of the game board 13. Thereby, as shown in FIG. 5B, the engagement pin 60 enters the engagement release hole 66 of the stopper 55. In this state, when the stopper 55 is slid to the lower engagement position, the engagement pin 60 enters the engagement hole 59 from the engagement release hole 66 as shown in FIG. The periphery of the engaging hole 59 of the stopper 55 is fitted into the fitting groove 65 of the stopper 60, and the stopper 55 is engaged and fixed to the engaging pin 60. If such an engaging operation is performed for the upper and lower stoppers 55, the right side of the game board 13 is pressed and fixed to the back part mounting portion 15 side by the stoppers 55 at the upper and lower two places. Is completed.
[0024]
Thereafter, when the game board 13 is removed, as shown in FIG. 5B, when the stopper 55 is slid to the upper non-engagement position, the engagement pin 60 is disengaged from the engagement hole 59. The engagement is released by exiting into the hole 66. In this state, if the hand is released from the knob 67 of the stopper 55, the stopper 55 is automatically rotated to the retracted position (the position indicated by the two-dot chain line in FIG. 7) by the torsional repulsive force of the torsion coil spring 57. . In this way, after the upper and lower two stoppers 55 are rotated to the retreat position, the game board 13 is swung forward with the stop sheet metal 41 as a fulcrum, and the left side of the game board 13 is moved from the stop sheet metal 41 to the right. The game board 13 is detached from the machine casing 11 by pulling the game board 13 in the direction.
[0025]
According to the embodiment described above, the mounting of the left side of the game board 13 is performed simply by inserting the fitting concave portions 50 and 52 on the left side of the game board 13 into the positioning base 43 and the positioning convex portion 51 and inserting the fitting concave portions 50 and 52 into the stopper plate 41. Well, no other work is needed. On the other hand, the mounting of the game board 13 on the right side only requires that the game board 13 inserted into the stopper plate 41 be swung backward and the stopper 55 is engaged with the engagement pin 60. Therefore, as compared with the above-described conventional configuration, the positioning operation is easy, the number of engagement points is small, and the mounting operation of the game board 13 is extremely simple. When the game board 13 is removed, the stopper 55 on the right side of the game board 13 is disengaged from the engaging pin 60, the game board 13 is swung forward, and the left side of the game board 13 is moved rightward from the stop metal plate 41. It only needs to be pulled off, and the work of removing the game board 13 is extremely simple.
[0026]
Further, in the above embodiment, the stopper 55 is provided so as to be rotatable in the front-rear direction and slidable in the up-down direction, and the right side of the game board 13 is pressed from the front side by rotating the stopper 55 backward. In this state, the stopper 55 is slid downward to engage with the engagement pin 60, so that the stopper 55 is engaged with the game board 13 while being pressed. The work can be performed very easily by the slide operation. In the above embodiment, the stopper 55 is slid “down” to engage with the engagement pin 60. However, the position of each part is adjusted so that the stopper 55 is slid “up” and engaged. The relationship may be changed.
[0027]
In addition, since the stopper 55 is rotationally urged by the torsion coil spring 57 to a position where it does not hinder the attachment and detachment of the game board 13, when the stopper 55 is detached from the engagement pin 60, the stopper 55 is moved. The torsion coil spring 57 automatically retreats to a position where it does not hinder the mounting and dismounting of the game board 13, so that the workability of attaching and detaching the game board 13 is further improved.
[0028]
In the above-described embodiment, the back part mounting portion 15 integrally formed with the machine frame 11 is also used as a positioning stopper (mounting recess of the game board 13) at the rear of the game board 13. A stopper different from the portion 15 may be provided on the machine frame 11. Further, in the above-described embodiment, the vertical positioning of the game board 13 is performed by three “positioning portions” of the two positioning projections 51 and the positioning base 43 provided on the left side of the machine frame 11. For example, the number of the “positioning portions” may be two or less, for example, the positioning table 43 may be omitted.
[0029]
Further, in the above embodiment, the swing type fitting member (stop plate 41) is provided on the left side of the machine frame 11 and the stopper 55 is provided on the right side of the machine frame 11. A swing type fitting member (stop metal plate 41) may be provided on the right side, and a stopper 55 may be provided on the left side.
[0030]
In addition, according to the present invention, the machine casing 11 is formed of a plastic material other than the ABS resin, or the swing type fitting member (stop metal plate 41) is provided at a plurality of locations, and the stopper 55 is provided at only one location. Needless to say, various changes can be made without departing from the gist of the invention.
[0031]
【The invention's effect】
As apparent from the above description, according to the configuration of claim 1 of the present invention, one side of the game board is inserted into the swing type fitting member provided on one of the left and right sides of the machine casing. , So that the other side of the game board is engaged and fixed by a stopper, so that the positioning operation is easier and the number of engagement points is smaller than that of the conventional configuration, The game board can be mounted and removed from the front side of the frame very easily. In addition, since the stopper is rotated and biased by the biasing means to a position where it does not hinder the attachment / detachment of the game board, when the stopper is released from the engagement member, the stopper is biased by the biasing means. It automatically retreats to a position where it does not hinder the attachment and detachment of the game board, and the workability of attaching and detaching the game board can be further improved.
[0032]
Further, according to the configuration of claim 2 of the present invention, the stopper is provided so as to be rotatable in the front-rear direction and slidable in the up-down direction, and the stopper is pressed to the engaging member by a sliding operation in a state pressed against the game board.
