A box storage 50i is formed.
[0029]
As shown in FIG. 8A, a board box 51 is fitted into the box housing portion 50i from the rear. As shown in FIG. 8 (b), the substrate box 51 is mainly composed of a transparent plastic cover 51a having one surface (front surface) opened and a box body 51b covering the opening of the cover 51a. In the board box 51, a circuit board 51c (see a in FIG. 8) is accommodated. The circuit board 51c is composed of a printed wiring board, and electronic components such as a control circuit (not shown) for driving and controlling the prize ball discharging device 15 are mounted on the circuit board 51c.
[0030]
A part of the circuit board 51c is exposed from the cover 51a as shown in FIG. 8A, and a connector (not shown) is mounted on the exposed part of the circuit board 51c. The cover 51a has a plurality of heat radiation holes 51d, and heat generated from the electronic components on the circuit board 51c is radiated through the plurality of heat radiation holes 51d.
[0031]
As shown in FIG. 9A, plate-like clamp bases 50d and 50d are integrally formed on the left and right side surfaces of the substrate base 50. As shown in FIG. A long plate portion 50e is integrally formed at the upper portion of 50d, and a short plate portion 50f is integrally formed at the lower portion. These plate portions 50e and 50f protrude rearward, and a metal clamp shaft 52 is fixed between the plate portions 50e and 50f of each set.
[0032]
A synthetic resin clamp member 53 is slidably and rotatably mounted on each clamp shaft 52. As shown in FIG. 8B, each of the clamp members 53 includes a base portion 53a having a quadrangular prism shape and a flange portion 53b protruding sideways from the base portion 53a. Is rotated in the direction of arrow A, as shown by a two-dot chain line, each flange 53b engages with the rear surface of the substrate box 51, and the substrate box 51 is clamped to the substrate base 50.
[0033]
Each clamp base 50d is integrally formed with a locking projection 50g as shown in FIG. 9 (d). Each of these locking projections 50g corresponds to a holding member, and when each clamp member 53 is pressed upward from the state shown in FIG. 8A, as shown in FIG. The clamp member 53 slides upward over the locking projection 50g. Then, each clamp member 53 is locked by the locking projection 50g and is held in a state of sliding upward.
[0034]
Each clamp base 50d is integrally formed with a stopper 50h corresponding to a restraining member. Each of these stoppers 50h has a plate shape protruding rearward as shown in FIG. 9D, and when each clamp member 53 slides upward, as shown in FIG. 9C. Furthermore, each clamp member 53 engages with the stopper 50h in a surface contact state, and the rotation operation of each clamp member 53 is restrained.
[0035]
Next, the operation of the above configuration will be described.
<About mounting the board box 51>
The board box 51 is fitted into the box storage part 50i of the board base 50 from the rear. Then, as indicated by the two-dot chain line in FIG. 8B, each clamp member 53 is rotated to the clamp position in the direction of arrow A, and the flange 53b of each clamp member 53 is engaged with the rear surface of the substrate box 51. Combine. Thereafter, each clamp member 53 is pressed upward, and is slid to an upper rotation restraining position over the locking projection 50g, and the rotation of each clamp member 53 is restrained by the stopper 50h.
[0036]
<Removal of board box 51>
Each clamp member 53 is pressed downward, and is slid to a lower rotation allowable position over the locking projection 50g. Then, each clamp member 53 is separated from the stopper 50h, and the rotation of each clamp member 53 is allowed. Therefore, as shown by the solid line in FIG. By rotating to the position, the engagement between the flange portion 53b of each clamp member 53 and the substrate box 51 is released. Then, the substrate box 51 is pulled rearward and removed from the box storage portion 50 i of the substrate base 50.
[0037]
According to the above embodiment, both sides of the substrate box 51 are clamped to the substrate base 50. For this reason, it is not necessary to form a flange portion for screw insertion in the substrate box 51, and it is not necessary to form a portion for receiving the flange portion in the substrate base 50. Therefore, the substrate box 51 and the substrate base 50 are reduced in size. . In addition, since it is not necessary to fasten a large number of screws into the substrate base 50, the assembling workability of the substrate box 51 with respect to the substrate base 50 is improved.
[0038]
Further, since the box support portion 50c is provided on the substrate base 50, the substrate box 51 can be positioned with respect to the substrate base 50 by fitting the substrate box 51 into the box support portion 50c. For this reason, since the clamp member 53 can be rotated while the substrate box 51 is positioned, the substrate box 51 can be stably attached to a fixed position of the substrate base 50.
[0039]
Further, a stopper 50 h that restrains the rotation of the clamp member 53 and a locking convex portion 50 g that restricts the slide of the clamp member 53 are provided. For this reason, the clamp member 53 is prevented from inadvertently sliding to the lower rotation allowable position or inadvertently rotating to the clamp release position in the opposite arrow A direction, so that the substrate box 51 and the substrate base 50 are prevented. It is prevented that the clamp in between is released.
[0040]
Further, the box support 50c, the locking projection 50g, the stopper 50h, and the clamp shaft 52 (clamp member 53) are provided on the substrate base 50. For this reason, there is no need to provide the clamp shaft 52 (clamp member 53), the locking projection 50g, the stopper 50h, and the like on the cover 51a of the substrate box 50, so the design restrictions on the cover 51a are reduced.
[0041]
Further, the clamp member 53 was held at the rotation restraint position by the locking convex portion 50g. For this reason, since it can respond only by integrally forming the latching convex part 50g in the board | substrate base 50, it becomes unnecessary to add the components which hold | maintain the clamp member 53 in a rotation restraint position.
[0042]
Next, a third embodiment of the present invention will be described with reference to FIGS. Note that the same members as those in the second embodiment are denoted by the same reference numerals and description thereof is omitted, and only different members will be described below. A compression coil spring 54 is attached to the outer periphery of each clamp shaft 52 as shown in FIG. Each of these springs 54 corresponds to a holding member, and holds the clamp member 53 in a rotationally restricted position where it is urged upward and is in contact with the plate portion 50e.
[0043]
Next, the operation of the above configuration will be described.
<About mounting the board box 51>
Each clamp member 53 is pushed down against the spring force of the spring 54, and as shown in FIG. 11 (a), is moved to a lower rotation allowable position away from the stopper 50h, and then (b) in FIG. As shown by the two-dot chain line, each clamp member 53 is rotated to the clamp release position in the direction of the opposite arrow A. In this state, after the board box 51 is fitted in the box housing portion 50i of the board base 50, each clamp member 53 is rotated to the clamp position in the direction of arrow A as shown by the solid line in FIG. Then, each flange 53 b is engaged with the rear surface of the substrate box 51.
[0044]
When each clamp member 53 is rotated in the direction of arrow A, the hand is released from each clamp member 53. Then, as shown in FIG. 10 (b), each clamp member 53 slides upward by the spring force of the spring 54, contacts the plate portion 50e, and stops at the rotation restraint position. Then, each clamp member 53 engages with the stopper 50h in a surface contact state, and the rotation of each clamp member 53 is restrained.
[0045]
<Removal of board box 51>
Each clamp member 53 is pushed down against the spring force of the spring 54, and is slid to a rotation allowable position away from each stopper 50h, as shown in FIG. Thereafter, as indicated by a two-dot chain line in FIG. 11B, each clamp member 53 is rotated to the clamp release position in the direction of the arrow A, and the engagement between each flange 53b and the substrate box 51 is performed. The substrate box 51 is removed from the box storage portion 50 i of the substrate base 50.
[0046]
According to the above embodiment, the clamp member 53 is held at the rotation restraint position by the spring 54. Therefore, even when the substrate box 51 is repeatedly attached and detached and the slide operation of the clamp member 53 is repeated, the holding force of the clamp member 53 by the spring 54 is held at a predetermined value, so that the clamp member 53 is held. The lowering of the force prevents sliding to the lower rotation allowable position.
