The arm portion 35a is bent at an acute angle toward the plate portion 31 in the vicinity of the connecting portion, so that the roller 35b can be engaged with an engaging convex portion 42b of the substrate box 40 described later.

  As shown in FIGS. 2 to 4, the board box 40 has a substantially rectangular parallelepiped box shape, and includes a board portion 41 corresponding to a circuit board on which a large number of electronic components are mounted, and a transparent plastic made over the board portion 41. A box-shaped cover 42 is provided. The substrate portion 41 is a rectangle having substantially the same dimensions as the substrate base 30. The cover 42 is placed on the substrate portion 41 except for the long portion 41a on the long side of the substrate portion 41, and is fixed to the substrate portion 41 at the periphery by screws or the like. A connector or the like (not shown) for connection is mounted on the long portion 41a exposed from the cover 42 of the substrate portion 41. As shown in FIG. 2, a locking recess 42a, which is a locking portion into which the engagement piece 34 is inserted, is provided on the side surface position of the cover 42 corresponding to the engagement piece 34 of the substrate base 30. It has been. In addition, an engagement convex portion 42 b that is a clamp engagement portion with which the clamp member 35 is engaged is provided on the upper surface position of the cover 42 on the short side side corresponding to the clamp member 35 of the substrate base 30. .

  The attachment of the substrate box 40 to the substrate attachment member 30 will be described. First, as shown in FIG. 5, the board box 40 is placed on the plate part 31, and the latching recess 42 a is inserted into the engagement piece 34 of the board mounting member 30, whereby the board box 40 is mounted on the board mounting member 30. Are supported by the engagement piece 34 and the support portion 32. Further, as shown in FIGS. 6 and 7, the board box 40 is easily and firmly fixed to the board mounting member 30 by engaging the roller 35 b of the clamp member 35 with the engaging convex part 42 b. Further, when it is desired to remove the board box 40 from the board mounting member 30, the roller 35 b can be removed from the engaging convex part 42 b and the board box 40 can be easily removed by pulling it toward the clamp member 35.

  According to the above embodiment, one side portion of the substrate box 40 is clamped to the substrate base 30, and the opposite side portion of the substrate box 40 is engaged with the substrate base 30. For this reason, it is not necessary to form a flange portion for screw insertion in the substrate box 40, and it is not necessary to form a portion for receiving the flange portion in the substrate base 30, so the substrate box 40 and the substrate base 30 are reduced in size, Even if the board box 40 and the board base 30 become larger, the extra mounting space associated therewith becomes unnecessary. In addition, since it is not necessary to fasten a large number of screws into the substrate base 30, the workability of assembling the substrate box 40 to the substrate base 30 is improved. Further, since the substrate box 40 is pressed against the substrate base 30 by the clamp member 35, the substrate box 40 can be firmly and reliably attached to the substrate base 30 even if the substrate box 40 is increased in size and weight.

  Moreover, since the engagement convex part 42b was provided in the board | substrate box 40, if the clamp member 35 is rotated, the clamp member 35 will engage with the engagement convex part 42b, and will be hold | maintained in the rotation state. For this reason, it is prevented that the clamp member 35 rotates and returns carelessly and the clamp between the substrate box 40 and the substrate base 30 is released. Moreover, the clamp member 35 which has the roller 35b was used. For this reason, since the roller 35b rotates when clamping the board | substrate box 40, the operating force of the clamp member 35 is reduced and operation of the clamp member 35 becomes easy. In addition, since the box support portion 32 is provided on the substrate base 30, the substrate box 40 can be positioned with respect to the substrate base 30 when the substrate box 40 is applied to the box support portion 32. For this reason, since the clamp member 35 can be rotated while the substrate box 40 is positioned, the substrate box 40 is stably attached to a fixed position of the substrate base 30.

  As a modification of the first embodiment, a pair of engaging convex portions 42 b are provided on both end edges of the substrate box 40, and a pair of clamp members 35 are provided on both ends of the substrate base 30. Both clamp members 35 may be engaged with both engaging convex portions 42b and fixed to the substrate base 30. Moreover, in the said 1st Example, although the connection part uses the roller clamp as a clamp member 35 as a clamp member 35, you may use the clamp member of the type which does not provide a roller. In the first embodiment, the clamp member 35 is rotatably mounted on the substrate base 30. However, the present invention is not limited to this. For example, the clamp member 35 is rotatably mounted on the substrate box 40. Then, the substrate base 30 may be clamped to the substrate box 40.

  In the first embodiment, the substrate box 40 is attached to the main set 11 via the substrate base 30. However, the present invention is not limited to this. For example, the clamp member 35 is attached to the main set 11 and the substrate is mounted. The box 40 may be clamped to the main set 11 by the clamp member 35. In this case, the main set 11 also serves as the substrate base. In the first embodiment, the rotatable clamp member 35 is used. However, the present invention is not limited to this. For example, a vise type that presses the substrate box 40 and the substrate base 30 from both sides to the other side. You may use the clamp member of. In the first embodiment, the right side portion of the substrate box 40 is engaged with the substrate base 30 and the left side portion is clamped to the substrate base 30. However, the present invention is not limited to this. One of them may be engaged with the substrate base 30 and the other may be clamped to the substrate base 30.

  Next, a second embodiment of the present invention will be described with reference to FIGS. The same members as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Hereinafter, only different members will be described. A synthetic resin substrate base 50 is fixed to the rear surface of the main set 11 as shown in FIG. The substrate base 50 has a horizontally long plate shape, and an L-shaped attachment plate portion 50a is integrally formed on the upper surface and the right side surface of the substrate base 50. The engagement plate portion 50a has two engagement holes. 50b is formed.

  Two engagement claw portions (not shown) are provided on the rear surface of the main set 11, and the engagement holes 50b of the substrate base 50 are pushed into the outer peripheral portions of the respective engagement claw portions. The claw portion is engaged with the peripheral edge portion of the engagement hole 50b. Further, a screw is tightened on the rear surface of the main set 11 through a mounting plate portion 50a, and the substrate base 50 is fixed to the main set 11 using both the engaging claw portion and the screw.

  As shown in FIG. 9A, a box support portion 50 c is integrally formed on the peripheral edge portion of the substrate base 50. As shown in FIG. 9B, the box support portion 50c has a wall shape protruding rearward, and a concave shape opening rearward is formed between the substrate base 50 and the box support portion 50c. A box storage 50i is formed.

  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.

  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.

  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.

  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.

  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.

  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.

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.
<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.

  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. 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.

  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. It is prevented that the clamp in between is released. 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. 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.

  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.

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.

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.
<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.

  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.

  In the second and third embodiments, the clamp member 53 is rotatably and slidably mounted on the substrate base 50. However, the present invention is not limited to this. For example, the clamp member 53 is mounted on the substrate box 51. May be mounted so as to be rotatable and slidable, and the substrate base 50 may be clamped to the substrate box 51. In the second and third embodiments, the substrate box 51 is clamped to the substrate base 50 by the flange portion 53b of the clamp member 53. However, the present invention is not limited to this, and for example, the base portion of the clamp member 53 A roller may be attached to 53a instead of the flange portion 53b, and the substrate box 51 may be clamped to the substrate base 50 by the roller.

  In the second and third embodiments, the left and right sides of the substrate box 51 are clamped to the clamp members 53. However, the present invention is not limited to this. For example, one of the left side and the right side of the substrate box 51 is used. May be engaged with the substrate base 50, and the other may be clamped to the substrate base 50 by the clamp member 53. In the second and third embodiments, the substrate box 51 is attached to the main set 11 via the substrate base 50. However, the present invention is not limited to this. For example, the clamp member 53 is attached to the main set 11. Then, the substrate box 51 may be clamped to the main set 11 by the clamp member 53. In this case, the main set 11 also serves as the substrate base. In the second and third embodiments, the left and right sides of the substrate box 51 are clamped by the clamp members 53. However, the present invention is not limited to this. For example, the upper and lower sides are clamped by the clamp members 53. Also good.
