Description

  The present invention relates to a board attachment structure for attaching a board to a plate-like fixing portion via a predetermined locking tool, and a gaming machine including the board attachment structure, and more particularly to a board attachment structure for attaching a small board such as an LED board. And a gaming machine including the board mounting structure.

  Many boards are attached to gaming machines such as pachinko machines and slot machines. As a board to be attached to the gaming machine, there are a control board such as a main control board and an effect control board, and a component mounting board on which functional parts such as a relay board, a switch, a sensor, and an LED (light emitting diode) are mounted. The LED board used for electrical decoration has the tendency for the number of attachments per game machine to increase.

  Conventionally, screws have been used to attach the substrate. However, in a gaming machine to which a large number of boards can be attached, the number of screwing points is enormous, which increases the manufacturing cost. Such an increase in cost related to board mounting becomes more prominent in a gaming machine to which a large number of small boards such as LED boards that are troublesome to fix with screws are attached.

  Therefore, it has also been proposed to attach the substrate by engagement without using screws. For example, in the gaming machine shown in Patent Document 1, ribs along the four sides of the board are projected from the fixed portion of the board, and a plurality of engaging claws are formed inside the rib. According to such a board mounting structure, the board mounting can be completed only by pushing the board into the ribs of the fixing portion and engaging with the engaging claws.

According to such a substrate mounting structure, it is possible to mount the substrate 30 by engagement without using a screw, but there is no need to project ribs along the four sides of the substrate 30 on the fixing portion 10. Therefore, it can avoid that the fixing | fixed part 10 and its metal mold | die become a complicated shape, and can suppress manufacturing cost.
Further, when the substrate 30 is attached, since the holding portion 21 of the locking tool 20 is elastically deformed, the engagement hole 22 of the locking tool 20 and the engagement claw 11 of the fixing portion 10 are engaged. Even in the fixing portion 10 made of an impossible material, the substrate 30 can be attached by engagement without using screws.

The fixed portion 10 has a front restricting portion 12 that restricts the movement of the substrate 30 in this direction on the front direction side (the U-shaped opening direction side), and the left and right direction side (the direction side orthogonal to the U-shaped shape). It is preferable to include a left and right restricting portion 13 that restricts the movement of the substrate 30 to the right.
If it does in this way, the movement to all the directions of the board | substrate 30 can be controlled with the movement regulation by the latching tool 20. FIG.

When the board | substrate 30 is provided with light emission means, such as LED31, it is preferable to provide the clamping part 21 of the latching tool 20 with the spreading | diffusion part 23 which diffuses the light from a light emission means.
In this case, since the locking tool 20 can also be used as a light diffusing member, the number of parts can be reduced and the cost can be reduced as compared with the case where a diffusing member is separately provided.

Next, the fixing part 10 and the locking tool 20 of the board mounting structure according to an embodiment of the present invention will be described in detail with reference to FIGS.
FIG. 6 is a diagram illustrating a fixing portion (substrate mounting portion) of a substrate mounting structure according to an embodiment of the present invention, where (a) is a perspective view of the fixing portion viewed from the back side, and (b) is AA sectional drawing of a fixing | fixed part, (c) is a rear view of a fixing | fixed part.
As shown in this figure, a substrate mounting portion T according to an embodiment of the present invention has a square tube portion penetrating in the front-rear direction, and the upper side wall portion of the square tube portion functions as the fixed portion 10, and a square shape. The left and right side walls of the tube portion function as the left and right restricting portion 13.

The substrate 30 (about 20 mm × 20 mm) is attached to a position along the lower surface side of the fixing portion 10, and the holding portion 21 of the locking tool 20 holds the substrate 30 together with the fixing portion 10 at this position. Thereby, the attachment state of the board | substrate 30 is maintained.
Then, the substrate 30 in the attached state is restricted from moving forward by the front restricting portion 12 that is formed to project to the front side of the lower surface of the fixed portion 10, and by the left and right restricting portions 13 that are formed from the left and right side walls of the fixed portion 10. The movement in the left-right direction is restricted, and the movement in the rearward direction is restricted by the clamping portion 21 of the locking tool 20.

  Further, on the upper surface side of the fixing portion 10, an engaging claw 11 that engages with the engaging hole 22 of the locking tool 20 is formed to protrude. The rear surface of the engaging claw 11 is an inclined surface 11 a whose height decreases toward the rear side, and the front surface of the engaging claw 11 is an upright surface 11 b that rises vertically from the fixed portion 10.

FIGS. 7A and 7B are views showing a locking tool of a board mounting structure according to an embodiment of the present invention, wherein FIG. 7A is a plan view of the locking tool, FIG. 7B is a front view of the locking tool, c) is a side view of the locking device.
As shown in this figure, the locking device 20 according to an embodiment of the present invention has substantially the same size as the substrate 30 (about 20 mm × 20 mm × 10 mm) and has a substantially cross-sectional shape that can be elastically deformed as a whole. It forms in the shape of a letter and constitutes a clamping part 21 that clamps the substrate 30 together with the fixing part 10.
Further, an engagement hole 22 that engages with the engagement claw 11 of the fixing portion 10 in a state where the substrate 30 is sandwiched is formed in the upper piece 21a of the sandwiching portion 21.

When the substrate 30 is attached, the engaging portion 22 is engaged with the engaging claw 11 of the fixing portion 10 by elastically deforming the holding portion 21.
That is, when the latching tool 20 is slid forward and inserted along the fixed portion 10 so as to hold the substrate 30 and the fixed portion 10, the upper piece 21 a of the holding portion 21 rides on the inclined surface 11 a of the engaging claw 11. Then, when the front end of the engagement hole 22 exceeds the upright surface 11 b of the engagement claw 11, the upper piece 21 a of the clamping portion 21 is elastically restored, and the engagement hole 22 is engaged with the engagement claw 11. Is engaged.
In a state where the engagement hole 22 is engaged with the engagement claw 11, the front end edge of the engagement hole 22 abuts on the upright surface 11 b of the engagement claw 11, so that the locking tool 20 moves backward. The contact portion 24 that is regulated and extends downward from the sandwiching portion 21 and the rear end surface of the substrate mounting portion T, and the substrate 30 between the front restraint portion 12 and the sandwiching portion 21 are engaged. The forward movement of the stopper 20 is restricted.

After the board 30 is attached as described above, when a cable (not shown) is connected to the connector 32 mounted on the upper surface of the board 30 and an LED driving current is supplied to the board 30, the board 30 is mounted on the lower surface of the board 30. The LED 31 is driven to emit light, and the front lower side of the board mounting portion T is irradiated.
At this time, the light from the LED 31 is diffused by the diffusion portion 23 covering the lower side of the LED 31. In particular, when the LED 31 is a chip LED, the light emission is in the form of dots, so that the illumination effect with good visibility without unevenness can be obtained by setting the diffused portion 23 to the surface light emission state.

The diffusing portion 23 of the present embodiment is configured by a thin plate portion extending forward from the lower piece 21b of the sandwiching portion 21.
Further, two ribs 21c projecting upward are formed on the lower piece 21b of the sandwiching portion 21, and by supporting the lower surface of the substrate 30 with these ribs 21c, the LED 31 and the diffusion portion 23 are predetermined. It comes to oppose with the space | interval of.
In addition, the diffusion part 23 can obtain a light diffusing function without unevenness by mixing a diffusing material with the molding material of the locking member 20 or making the molding material milky white.

Next, the locking tool 20 and the substrate 30 are slid into the fixing portion 10 from behind and inserted. At this time, the upper piece 21 a of the sandwiching portion 21 is along the upper surface of the fixing portion 10, and the substrate 30 is along the lower surface of the fixing portion 10.

  When the locking tool 20 and the substrate 30 are slid forward along the fixing portion 10, the upper piece 21 a of the clamping portion 21 rides on the inclined surface 11 a of the engaging claw 11 and elastically deforms upward. When the front end of the joint hole 22 exceeds the upright surface 11 b of the engagement claw 11, the upper piece 21 a of the holding portion 21 is elastically restored, and the engagement hole 22 is engaged with the engagement claw 11. Thereby, the attachment of the substrate 30 is completed.

  In a state where the engagement hole 22 is engaged with the engagement claw 11, the front end edge of the engagement hole 22 abuts on the upright surface 11 b of the engagement claw 11, so that the locking tool 20 moves backward. The abutting portion 24 that is regulated and extends downward from the clamping portion 21 abuts on the rear end surface of the substrate mounting portion T, and is locked by the substrate 30 between the front regulating portion 12 and the clamping portion 21. The forward movement of the tool 20 is restricted.

  Further, the attached substrate 30 is restricted from moving forward by the front restricting portion 12 formed to protrude to the lower front side of the fixed portion 10, and by the left and right restricting portions 13 made of the left and right side walls of the fixed portion 10. The movement in the left-right direction is restricted, and the movement in the rearward direction is restricted by the clamping portion 21 of the locking tool 20.

Then, after the board 30 is attached, when a cable (not shown) is connected to the connector 32 mounted on the upper surface of the board 30 and an LED driving current is supplied to the board 30, the board 30 is mounted on the lower surface of the board 30. The LED 31 is driven to emit light, and the lower front side of the board mounting portion T is irradiated.
At this time, the light of the LED 31 is diffused by covering the lower part of the LED 31 with the diffusion portion 23 of the locking tool 20.

The LED 31 has an end face 9b-1 of the lower opening 9b. Is disposed opposite to the incident portion 9b-2.

Specifically, as shown in FIG. 3, the LED 31 is disposed so as to face the incident part 9 b-2 via the diffusion part 23, and the light diffused by the diffusion part 23 is transmitted from the incident part 9 b-2 to the front surface. The light enters the panel 9. This incident light propagates downward in the front panel 9 and exits to the outside from the lower end face. That is, the front panel 9 serves as a light guide plate, and the lower end surface of the front panel 9 emits light. At this time, since the lower end surface emits light by the light diffused by the diffusing portion 23, it emits light uniformly over a wide range without emitting light in a dotted manner.
Thus, while LED30 is used as the board | substrate 30 which concerns on a board | substrate attachment structure, LED31 is provided so that it may oppose the end surface 9b-1 of the front panel 9 used as a translucent member via the spreading | diffusion part 23, LED31. Is incident on the end surface 9b-1 via the diffusion portion 23, and propagates through the front panel 9 and exits from the lower end surface, so that the lower end surface can emit light uniformly over a wide range. .

There is no need to project ribs along the four sides of the substrate 30 on the fixed portion 10. As a result, it is possible to avoid the fixing portion 10 and its mold from becoming complicated shapes, and to suppress the manufacturing cost.

Further, when the substrate 30 is attached, since the holding portion 21 of the locking tool 20 is elastically deformed, the engagement hole 22 of the locking tool 20 and the engagement claw 11 of the fixing portion 10 are engaged. Even in the fixing portion 10 made of an impossible material, the substrate 30 can be attached by engagement without using screws.
Moreover, the range irradiated with the light diffused by the diffusion part 23 can be expanded by using the substrate 30 as the LED substrate.
