Abstract

PROBLEM TO BE SOLVED: To quickly and easily mount a wiring board with one-touch operation by providing an elastic piece that receives one end part of the wiring board for pressing at one side end of a mounting plate, by allowing a gear-lock part that gear-locks the other to project at the other, and by holding the wiring board for fixing. SOLUTION: One end 14a of a wiring board 14 is applied to reception parts 18 and 18 of an elastic piece 17 of a mounting plate 15. Then, force is applied, and the wiring board 14 is pushed downward for bending the elastic piece 17. In this state, the other end 14b of the wiring board 14 is gear-locked to a gear- locking part 19 while the other end 14b is being pressed to the mounting plate 15, thus bringing the wiring board 14 into contact with a reception stage part 20 and the elastic piece 17. Holding and fixing can be made between the elastic piece 17 and the gear-lock part 19 by pressing to the side of the gear-lock part 19 by the spring force of the elastic piece 17. To remove the wiring board 14 being fixed to the mounting plate 15 as needed, the elastic piece 17 is pressed downward, and at the same time the other end 14b of the wiring board 14 may be removed from the gear-lock part 19 of the other side end.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of the electric accessory A employing the wiring board mounting structure of the present invention as viewed from the front, and FIG. 2 is a perspective view as viewed from the back. The electric accessory A has a variable display 2 mounted on an upper half of a front surface of a mounting board 1 mounted on a game board (not shown), and a variable winning opening 3 mounted on a lower half thereof. On the front surface of the variable display 2, a screen 4 for displaying a plurality of symbols such as a plurality of numbers, characters, patterns, etc. is provided. On the upper part, a prize hole 6 for opening and closing a pair of movable wing pieces 5, 5 is provided. I have. A pair of movable wings 7, 7 that open and close on both sides of the lower part of the variable winning opening 3 are pivotally mounted, and a display unit 8 that displays the number of opening operations of the movable wings 7, 7 is provided on the lower front surface. ing.

Further, a plurality of decorative lamps 9 are provided on both sides of the screen 4 and the variable winning opening 3 respectively. A case body 10 that forms a spherical passage is provided on the back surface of the mounting plate 1, and the movable wing pieces 5, 5 are provided on the back surface of the case body 10.
Solenoids 11 and 12 for opening and closing the switches 7 and 7 are mounted.

[0008] When a hit ball wins a starting winning opening (not shown) mounted on the game board, the numbers and the like on the screen 4 fluctuate, and satisfy a specific condition, for example, when the same numbers are arranged,
The movable wing pieces 5, 5 are opened for several seconds. During this time, if a hit ball wins in the prize-winning opening 6, a special right can be obtained. 7, 7 keep releasing until a predetermined time (for example, 30 seconds) or 10 winning balls are counted, so that many winning balls are generated at one time. The number of times the movable wing pieces 7, 7 are opened is generally set to 16 times, and the number of times is displayed on the display unit 8.

Reference numeral 13 denotes a plurality of support rods protruding rearward from the back surface of the case body 10. A mounting plate 15 for mounting a wiring board 14 described later is screwed to the rear end of the support rods 13. The mounting plate 15 is formed in a rectangular shape, and its periphery is formed in a box shape surrounded by an edge frame 16. Of the pair of opposing side ends (upper and lower ends in FIG. 3), a lower side frame 16 a is provided. The support piece 17b from the central base end 17a
Arc-shaped elastic piece 1 formed by bifurcating 17b
7, and receiving portions 18, 18 are provided at the upper ends of the support pieces 17b, 17b. Also, the side frame 16 at the upper end
b has a locking portion 19 facing inward. Reference numeral 20 denotes a receiving step provided along the inside of the side frame 16b.

The wiring board 14 has a size substantially matching the mounting plate 15, and has a surface on which a display section 8, decorative lamps 9, or electric wiring (not shown) such as solenoids 11 and 12 are connected. Electric parts such as 21 and electric resistance 22 are attached. Further, notches 23 are provided at the lower end portions on both sides to abut against the receiving portions 18 at the distal end of the elastic piece 17. Further, the wiring board 14 is provided with recesses 23 ', 23' and through holes 24 at the upper corners and at the center where the screw heads of the mounting plate 15 fixed to the support rod 13 face.

The mounting structure of the wiring board according to the present invention has the above-mentioned structure, and one end 14a (the lower end in FIG. 3) of the wiring board 14 is applied to the receiving portions 18 of the elastic piece 17 of the mounting plate 15. The elastic piece 17 is deflected by applying a force to push down the wiring board 14 downward, and in this state, the other end 14 b (upper end in FIG. 3) of the wiring board 14 is pressed against the mounting plate 15 while the locking portion 19 is pressed. When the wiring board 14 is stopped, the wiring board 14 comes into contact with the receiving step portion 20 and the elastic piece 17, and is pushed toward the locking portion 19 by the elastic force of the elastic piece 17, and the elastic piece 17 and the locking portion 19 are pressed. And fixed between them. Thus, the mounting of the wiring board 14 is completed. In order to remove the wiring board 14 fixed to the mounting plate 15 from the mounting plate 15 as necessary, the elastic piece 17 is pressed downward while the wiring board 14 is Can be easily removed by removing the other end.

FIG. 6 shows another embodiment, in which contact portions 25, 25 are provided at the tips of receiving portions 18, 18 provided on both support pieces 17b, 17b of the elastic piece 17, respectively.
Is extended. In this embodiment, the wiring board 14
Notches 23, 23
Since the contact portions 25, 25 that engage with the abutment contact the surface of the wiring board 14, the contact portions 25, 25 are securely fixed without easily falling off.

FIG. 7 also shows another embodiment, in which the inside of side frames 16c and 16d of another pair of side ends (left and right side ends in the figure) of the mounting plate 15 facing each other. Are provided with locking portions 19a, 19a facing the elastic pieces 17, and the wiring board 14 is provided with cuts 26, 26 to be engaged with the locking portions 19a, 19a. Also in this embodiment, as in the embodiment in which the contact portions 25, 25 are provided, the locking portions 19a, 19a engage with the cuts 26, 26 to engage the side ends 14c, 14d of the wiring board 14. Because it stops, it does not fall off easily. Note that, in addition to the above-described embodiment, all the locking portions 19 and 19a and the contact portion 25 may be provided.
Further, a cover plate 27 is provided on both sides of the lower end 16a of the mounting plate 15.
27, and the wiring board 14 is provided inside the cover plates 27, 27.
By inserting both ends of the lower end portion 14a, the mounting state can be made extremely strong. Note that, in the embodiment of the present invention, the case where the mounting structure of the wiring board is applied to the back surface of the electric accessory is described, but in addition to this, the back surface of the pachinko machine, for example, a mechanism plate mounted there, It can be applied to any part to which a wiring board is attached, such as a control board box for controlling a game state, a terminal board, etc., and can be applied to general electric equipment having a wiring board other than a pachinko machine. Of course.

[0014]

As described above, in the wiring board mounting structure of the present invention, since the wiring board is sandwiched and fixed between the locking portions of the mounting plate and the elastic pieces, the mounting is easy by one-touch operation. And the working efficiency is improved. Further, since the wiring board mounted on the mounting plate is firmly held by the locking portion or the contact portion, there is no possibility that the wiring board will fall off. In addition, since the wiring board can be easily and easily removed when it is removed, the pachinko machine has advantageous effects such as being convenient when the electric accessory is replaced due to failure.
