That is, the lateral length W1 of the first sub printed circuit board 310 is shorter than the lateral length W2 of the second sub printed circuit board 320. As described above, the structure is such that the two printed circuit boards 310 and 320 having different areas can be mounted interchangeably.

  The case cover 251 is attached to the front surface of the image control board 71, and on the back surface (inner surface) of the area where the first sub printed circuit board 310 is mounted, as shown in FIG.

The cable holding portions 371 to 374 are elastic bodies having a C-shape, and one end is fixed on the surface of the guide main body 351 and the other end is not fixed. When the cable is pushed into the inside from the non-fixed end, the cable is held in the inside. The second cable guide portion 370 is formed such that the directions of the non-fixed ends of the cable holding portion 373 and the cable holding portion 374 are different by 180 degrees. The cable in the cable holding part can be taken out from the non-fixed end side.

The pawl portion 395 is inserted. Thereafter, the cable guide unit 350 is slid in the arrow direction (Y direction) as shown in FIGS. 15 (c1), (c2), (d1), and (d2).

When the lock receiving portion 396 is provided on the case base 201, the security of the image display unit 70U is lowered due to the opening of the lock receiving portion 396, but the cable guide unit 350 is slid and attached to the case base 201. Thus, since the guide body 351 of the cable guide unit 350 can close the opening of the locking receiving portion 396 of the case base 201, it is possible to prevent the security of the image display unit 70U from being lowered.
In this embodiment, since the locking claw portion 395 is integrally formed with the cable guide unit 350, the opening 397 is also formed in the guide body 351 of the cable guide unit 350.

For example, a cable holding portion or a straight guide portion may be directly formed on the case base 201.

In conventional gaming machines, there are many cables drawn from various boards and cables that connect other boards across the boards, and the routing is troublesome.

It becomes possible to improve the quality of the gaming machine 1.
Further, in the gaming machine 1 of the present embodiment, the first cable guide portion (guide means) 360 includes a cable holding portion (first guide means) 361 and a linear guide portion (in which the shape of the cable holding portion 361 is different) ( 2nd guide means) 362, for example, the work of attaching the cable to the cable guide part, compared to the case where all the guide parts are constituted by the C-shaped cable holding part, for example, the work of attaching the cable is relatively troublesome Becomes easier.
Further, in the gaming machine 1 of the present embodiment, when a plurality of C-shaped cable holding portions are provided in the cable guide portion, for example, a plurality of C-shaped cable holding portions 361 are provided in the first cable guide portion 360. In this case, when the directions of the non-fixed end portions of the two adjacent cable holding portions 361a and 361b are alternately different by 180 degrees, there is an advantage that the cable 410 is difficult to come off.

Since the wiring pattern PT3 of the third voltage supply line that supplies the drive voltage to the solenoid, the motor, etc. consumes more power than the first voltage supply line, it is desirable to set the pattern width to 2 mm or more, for example.
Since the wiring pattern PT2 of the second voltage supply line that supplies the driving voltage to the lamp or the like consumes a large amount of power, it is desirable to set the pattern width to 3 mm or more, for example.
In addition, in order to prevent the influence of noise from the outside, it is desirable that the GND pattern be formed so that portions other than the signal pattern and the power supply pattern are grounded (grounded) to GND (so-called solid ground).

In the printed wiring board 701, a single-side mounting method in which various electronic components and connectors are mounted only on the component surface 701a of the printed wiring board 701 is employed as a mounting method for mounting electronic components.
Further, in the printed wiring board 701, various electronic components such as an insertion mounting type (through hole mounting type) resistor R, capacitor C, transistor Tr, and IC and a connector CN are mounted in a through hole (component insertion hole) formed in the substrate.

<Board structure of image control board>
Next, the substrate structure of the image control substrate will be described with reference to FIGS.
26A and 26B are diagrams for explaining the structure of the image control board. FIG. 26A is a diagram showing the configuration of the component surface (front surface) of the image control board, and FIG.

The image control board 71 uses a printed wiring board 801 in which wiring patterns are formed on both sides of the printed board.
In the present embodiment, the image control board 71 has been described as an example using the printed wiring board 801. However, this is only an example. In the image control board 71, wiring is provided on both sides and the inner layer side of the printed board. A multilayer printed wiring board on which a pattern is formed may be used.
As a mounting method when electronic components are mounted on the printed wiring board 801, various surface mounting type electronic components can be used on the connection electrodes (lands) 802 formed on both surfaces (component surface 801a and solder surface 801b) of the printed wiring board 801. A surface mounting method for mounting connectors and the like is employed. That is, the image control board 71 is configured using a surface-mount type printed wiring board 801.
The production control board 40, the payout control board 50, the lamp control board 60, the relay board 75, the launch control board 80, and the power supply board 90 have the same structure as the image control board 71, that is, surface-mount type printed wiring. Since it is constituted by a substrate or a multilayer printed wiring board, the description is omitted.

  As described above, in the gaming machine 1 of the present embodiment, the main control board 30 is provided with a printed wiring board (a first wiring board) provided with a through hole into which a lead of an insertion mounting type electronic component (hereinafter referred to as “insertion mounting component”) can be inserted. Printed circuit board) 701, and a printed wiring board (second circuit board) having a connection electrode that can be connected to a connection terminal of a surface mount electronic component (hereinafter referred to as "surface mount component") by a substrate other than the main control substrate 30 Printed circuit board) 801.

By the way, a gaming machine installed in a game store such as a hall is used under severe temperature conditions, and thus various control boards mounted are susceptible to external stress (thermal stress). Therefore, although there is no problem in the main control board 30 in which the mounting component is an insertion mounting component, in the control board in which the mounting component is a surface mounting component, for example, the image control board 71 or the like, the connection terminal of the surface mounting component is caused by thermal stress. And cracks in the solder that electrically connects the printed wiring board and the connection electrodes of the printed wiring board may cause problems.
In particular, when the surface mount component is a connector, in addition to the thermal stress described above, external stress is also applied when the cable is inserted / removed, resulting in solder cracks compared to other surface mount components such as resistors and capacitors. There is a risk that an electrical failure may occur.

  In the mounting process of mounting the surface-mounted component on the printed wiring board, cream solder is applied in advance to the connection electrodes formed on the printed wiring board by printing or the like. Next, the surface mount component is placed at a predetermined position on the printed wiring board to which the cream solder is applied. Thereafter, the surface mounted component is mounted on the printed wiring board by heating the printed wiring board on which the surface mounted component is mounted to melt the solder. However, the mounting process has a problem in that a positional shift occurs in the surface-mounted component mounted on the printed wiring board.

  Therefore, in the gaming machine 1 of the present embodiment, the connection electrode groups respectively connected to the connection terminals of one surface-mounted component formed on the printed wiring board are configured as follows.

FIG. 28 is an enlarged view of a part of a printed wiring board used for the image control board.
As shown in FIG. 28, in the printed wiring board (second printed board) 801, land groups 811 and 812 are configured by lands 802 connected to connection terminals of one surface-mounted component.
For example, if the surface mount component is the IC 850 shown in FIG. 26A, a land group 811 for the IC 850 is configured on the printed wiring board 801 by a plurality of lands 802 connected to a plurality of lead terminals of the IC 850, respectively. The In this specification, a plurality of lands 802 respectively connected to a plurality of lead terminals of one surface-mounted component are referred to as a land group.
Similarly, if the surface mount component is the connector 851 shown in FIG. 26A, a land for the connector 851 is provided on the printed wiring board 801 by a plurality of lands 802 respectively connected to a plurality of lead terminals of the connector 851. A group 812 is configured.
The plurality of lands 802 constituting the land groups 811 and 812 include a first land 802a and a second land 802b having a shape different from that of the first land 802a.
Specifically, among the plurality of lands 802 constituting each of the land groups 811 and 812, the shape of the four corner lands 802b is larger than that of the other lands 802a (for example, about 1.5 times).

  As described above, the gaming machine 1 according to the present embodiment includes the main control board 30 that controls the game and the image control board (production board) 71 that controls the effect. The printed circuit board (first printed circuit board) 701 having a through hole (insertion hole) 702 into which the lead electrode is inserted, and the image control board 71 is connected to a connection terminal of a surface mount component (connection) An electrode) 802 includes a printed wiring board (second printed board) 801. The printed wiring board 801 has one land group (connection electrode group) by a plurality of lands 802 respectively connected to a plurality of connection terminals of one surface mount component, and one land group 802 (connection electrode) The group) is configured to have a land 802a (first connection electrode) and a land 802b (second connection electrode) having an area (large) different from that of the first connection electrode.

With this configuration, when a solder paste is applied to the lands 802 of the printed wiring board 801 in a mounting process for mounting surface-mounted components such as the IC 850 and the connector 851 on the printed wiring board 801, for example, a land group 811 corresponding to the IC 850 In the land group 812 corresponding to the connector 851, the amount of cream solder applied to the four corner lands 802b is larger than that of the other lands 802a.
Thus, for example, after mounting a surface mount component such as an IC 850 or a connector 851, the bonding strength between the printed wiring board 801 and the surface mount component can be increased. Even when stress is applied to the solder, it is possible to prevent cracks from occurring in the solder at the joint.
Further, when the surface mount component is the connector 851, there is an advantage that cracks are hardly generated in the solder at the joint portion of the printed wiring board 801 and the connector 851 due to external stress applied when the connector cable is inserted into and removed from the connector 851. is there.

  In particular, since the gaming machine 1 of the present embodiment is used under severe temperature conditions, external stress (thermal stress) or the like is applied to the printed wiring board 801 used in the image control board 71 or the like. Even in such a case, there is an advantage that cracks can be prevented from occurring in the solder at the joint portion between the printed wiring board 801 and the surface mount component.

  Furthermore, according to the present embodiment, when the cream solder is applied to the lands 802 of the printed wiring board 801 in the mounting process of mounting the surface-mounted components on the printed wiring board 801, the land group 811 and the connector 851 corresponding to the IC 850 are applied. Since the amount of cream solder applied to the four corner lands 802b is larger than the other lands 802a, the self-alignment effect during mounting, that is, the surface of the land 802 of the printed wiring board 801 When mounting the mounting component, it is possible to enhance the effect of positioning the surface mounting component at the correct position by the surface tension of the melted solder until the cream solder applied to the four corner lands 802b is melted and solidified. .

In the gaming machine 1 of the present embodiment, a connector 852 having a fixing terminal as shown in FIG. 26A is mounted as a surface mounting component. In this case, as shown in FIG. 28, the printed wiring board 801 includes seven lands 802a connected to a plurality of lead terminals of the connector 852, and two lands 802c for fixing the connector. A land group 813 is configured. In the gaming machine 1 of the present embodiment, depending on the use of the connector 852, the connector fixing land 802c may be grounded to the ground (GND) or may not be grounded to the GND.
For example, when used in an environment where the housing (main body) of the connector 852 is easily charged, that is, when it is desired to remove static electricity (noise) charged in the housing of the connector 852, the connector fixing land 802c is grounded to GND.
With this configuration, the connector 852 can be more firmly fixed, and static electricity charged in the housing can be reliably removed.
In contrast, if the reference level of the signal transmitted by the lead terminal of the connector 852 is not the GND reference, the connector fixing land 802c is not grounded to the GND.
If comprised in this way, while the connector 852 can be fixed more firmly, the reliability (safety) of the signal transmitted can be improved.

  As described above, the gaming machine 1 according to the present embodiment includes the main control board 30 that controls the game and the image control board (production board) 71 that controls the effect. The printed circuit board (first printed circuit board) 701 having a through hole (insertion hole) 702 into which the lead electrode is inserted, and the image control board 71 is connected to a connection terminal of a surface mount component (connection) An electrode) 802 includes a printed wiring board (second printed board) 801. The printed wiring board 801 includes lands 802a (connection electrode regions) connected to connection terminals of one surface-mounted component and lands 802c (fixed regions) that fix one surface-mounted component. If comprised in this way, it will become possible to fix surface mounting components more firmly.
