Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to an electronic circuit unit that is incorporated into electronic game machines such as slot machines, pachinko machines, and video game machines.

<Prior Art> This type of electronic game machine incorporates a large number of circuit boards on which control circuits for controlling mechanical operations are mounted. In order to incorporate these circuit boards in an aligned manner into the limited internal space of the machine, a housing for accommodating a plurality of circuit boards is installed at appropriate locations in the internal space. At the bottom of this housing, a plurality of connectors are aligned and arranged, and a guide groove is formed at a position perpendicular to and facing the connectors, and by inserting both edges of the circuit board into this guide groove and pushing it, the circuit board A connecting terminal is coupled to the connector. This structure has the advantage that it is easy to assemble the circuit board and connect it to the connector, and that the circuit board can be easily inserted and removed during inspection and repair.

Incidentally, control of entertainment business machines such as slot machines must be carried out based on legal requirements, and the setting of the control state is carried out by each machine manufacturer. Therefore, it is illegal to arbitrarily adjust or modify the control circuits in amusement facilities where this type of machine is installed.

In order to prevent this illegal act, a method was devised in which a circuit board enclosed in a protective case was incorporated into a machine, and a circuit unit suitable for such use was also proposed (Japanese Utility Model Publication No. 55-8304).
Publication No.).

<Problems to be solved by the invention> However, the circuit unit described in the publication does not have a structure in which both end surfaces of the protective case can be inserted into the housing, so this type of circuit unit can be used as is in the current model. Therefore, it is necessary to improve the protective case and provide slide pieces protruding from both end faces to engage in the guide groove.

This invention was made in view of the above problem, and aims to provide an electronic circuit unit that can fit into the guide groove of the housing without forming a special slide piece on the side of the protective case. purpose.

<Means for Solving the Problems> The electronic circuit unit of this invention consists of a circuit board with a rectangular planar shape on which electronic components are arranged, and a protective case with a rectangular planar shape that covers the circuit board.

The circuit board has a width larger than the protective case, and a connection terminal connected to a connector is formed on one side perpendicular to the width direction.

The circuit board is placed in a protective case, the connection terminals are made to protrude from the front end surface of the protective case to the outside of the case, and both edges are made to protrude from both end surfaces of the protective case to the outside of the case, and the circuit board and the protective case are connected. are integrally fixed, and both edges of the circuit board protruding from the protective case are formed as sliding pieces.

<Function> The connecting terminal is connected to the connector by inserting the slide piece into the guide groove and pushing the electronic circuit unit, and the slide piece is formed by making both edges of the circuit board protrude from both end faces of the protective case. Therefore, there is no need to provide a sliding piece protruding from the side of the protective case.

<Embodiment> FIG. 1 shows an electronic circuit unit 6 according to an embodiment of this invention installed in an electronic device 1 such as a slot machine.
This shows the state in which it is installed.

A housing 2 for incorporating an electronic circuit unit 6 is attached to a suitable position in the internal space of the electronic device 1, a connector 21 is attached to the bottom of the housing 2, and an electronic circuit is installed at a position orthogonal to and opposite to the connector 21. Connect unit 6 to connector 2
A guide groove 22 is formed to guide the guide to the 1.

The electronic circuit unit 6 includes a circuit board 3 having a rectangular planar shape, and a protective case 4 having a rectangular planar shape that covers the circuit board 3.

The circuit board 3 has a width larger than that of the protective case 4, and has a large number of electronic components 32 mounted on the surface of a printed circuit board 31, as shown by imaginary lines in FIG. This circuit board 3 has a connection terminal 3 to the connector 21 on one side perpendicular to the width direction.
3, and a predetermined width of both side edges perpendicular to the connecting terminal 33 is provided in the guide groove 22 of the housing 2.
The slide piece 34 is engaged with the slide piece 34.

The protective case 4 is a synthetic resin case, and as shown in FIGS. 2 to 5, it has a dish-shaped case body 4 that covers the surface of the electronic component 32 side of the circuit board 3.
1, and a hinge part 45 on one side of this case body 41.
A lid 4 that covers the back side of the circuit board 3 that is connected via the
It consists of 6.

On the front of the protective case 4, there is a case body 41.
A portion of the peripheral wall 42 of the circuit board 3 is cut out to form a take-out part 43 for the connecting terminal 33 on both sides of the hinge part 45, and the upper edge of the surrounding wall 42 is formed on both end surfaces perpendicular to the hinge part 45. A substrate edge extraction portion 44 is formed by lowering the thickness by the thickness of the substrate. Protective case 4
The corners of the case body 41 and the lid 46 correspond to the positioning holes 35 drilled in advance in the circuit board 3.
A stopper hole 47 is provided opposite to the stopper hole 47 .

positioning the circuit board 3 in a protective case 4;
The connecting terminal 33 is made to protrude from the front end surface of the protective case 4 to the outside of the case, and both edges thereof are made to protrude from the both end surfaces of the protective case 4 to the outside of the case. The circuit board 3 is integrally fixed with the protective case 4, and at this time, both side edges of the circuit board 3 protruding from the protective case 4 constitute slide pieces 34.

The rear end surface of the main body case 41 abuts against the lid 46,
An opening/closing regulating means 5 is provided between this rear end surface and the lid 46.

The opening/closing regulating means 5 of this embodiment has a seal 50 attached to the rear end surface and a part of the corresponding lid 46 as attachment surfaces, and the circuit board 3 is removed from the protective case 4 after being shipped from the manufacturer. If the seal 50 breaks, this can be determined by the breakage of the seal 50. Furthermore, the opening/closing regulation means 5
If necessary, the case body 41 and part of the lid 46 may be welded together, but in this case, the circuit board 3 cannot be removed.

When storing the electronic circuit unit 6 in the housing 2 of the electronic device 1, as shown in FIG. Slide the electronic circuit unit 6 in the direction of arrow a until the portion 33 is coupled to the connector 22.

<Effects of the invention> As described above, this invention forms a slide piece that projects into the guide groove by making both edges of the circuit board protrude from both end faces of the protective case. This has the advantage that the electronic circuit unit can be inserted into the guide groove without having to do so.
