It is formed in a conical point 5d so that it can be inserted smoothly into the a. The connection between each contact pin 5c and each wiring 5b is held by solder 5e.

The light source device for a gaming machine according to the first embodiment is
The light source 1, the buffer pedestal 3, the support pedestal 4, and the wiring board 5 shown in FIG. 2 are assembled into the form shown in FIG. 1 through the form shown in FIG. That is, the lead wire 1d of the light source 1 shown in FIG.
The light-transmitting bulb 1a of the light source 1 is housed in the housing 3a. At this time, the bottom outer peripheral surface of the light transmissive bulb 1a pushes outward the edge of the buffer pedestal 3 constituting the annular peripheral wall of the storage section. Then, the bottom of the light-transmitting bulb 1a contacts the bottom of the housing 3a,
The light source 1 is seated on the housing 3a of the buffer base 3. After the light source 1 is seated, the edge of the buffer pedestal 3 that has been pushed outwardly shrinks inward due to its own restoring elasticity, and comes into close contact with the outer peripheral surface of the bottom of the light-transmitting bulb 1a and holds the light source 1. Have. Thereafter, the lead wire 1d protruding from the lower end surface of the buffer pedestal 3 is inserted into the guide hole 4a of the support pedestal 4. Then, the buffer pedestal 3 and the support pedestal 4 are brought closer to each other, and the lower end surface of the buffer pedestal 3 is brought into contact with the upper end surface of the support pedestal 4. As described above, the light source 1 includes the buffer base 3 and the support base 4.
In the form of wearing, the plurality of lead wires 1d drawn out from the lower end surface of the support base 4 are folded upward at the lower end surface of the support base 4 so as not to contact each other. By turning back the lead wire 1d, as shown in FIG.
The seating form of the light source 1 on the buffer pedestal 3 and the overlapping form of the support pedestal 4 on the buffer pedestal 3 are maintained.

Finally, the pedestal 2 combined with the light source 1 while maintaining the folded form of the lead wire 1d shown in FIG.
Of the through hole 3b and the guide hole 4a are inserted into the contact pins 5c of the wiring board 5. That is, the support base 4
Guide hole 4a and through hole 3 of buffer base 3
b is pushed into the contact pins 5c of the wiring board 5. At this time, the contact pins 5c are aligned with the guide holes 4a, and the contact pins 5c are inserted into the guide holes 4a. The alignment between the contact pin 5c and the guide hole 4a is most preferably such that the contact pin 5c and the guide hole 4a are coaxial, but the top of the point 5d of the contact pin 5c fits inside the guide hole 4a. Should be fine. In this state, the pedestal 2 and the wiring board 5 combined with the light source 1 are relatively moved in a direction approaching each other, so that the contact pins 5c are elastic via the guide holes 4a of the rigid support pedestal 4. Since the lead is inserted into the through hole 3b of the buffer base 3, the contact pin 5c is inserted.
Of the lead wire 1d and the contact pin 5c can be prevented from occurring.

That is, the tip 5d of the contact pin 5c enters the guide hole 4a by the movement of the pedestal 2 and the wiring board 5 combined with the light source 1. In the process of this approach, the inclined surface of the point 5d of the contact pin 5c slides on the lower end surface peripheral portion of the guide hole 4a of the support base 4, so that the contact pin 5c and the guide hole 4a become coaxial. Be matched. As the contact pins 5c continue to enter the guide holes 4a, the contact pins 5c enter the through holes 3b of the buffer pedestal 3 while sandwiching the lead wire 1d between the contact pins 5c and the guide holes 4a of the support pedestal 4. The contact pin 5c pushes the through hole 3b of the buffer pedestal 3 against the elasticity of the buffer pedestal 3. In the process in which the contact pin 5c enters the guide hole 4a with the lead wire 1d interposed between the guide pin 4c and the guide hole 4a, the contact pin 5c rubs the surface of the lead wire 1d because the support base 4 is hard. , Contact pin 5c
Breaks the naturally formed oxide film and connects to the lead wire 1d.

When the hole of the pedestal 2 combined with the light source 1 is inserted into the contact pin 5c of the wiring board 5, the contact pin 5c is displaced from the guide hole 4a.
When trying to insert the contact pin 5c into the guide hole 4a, since the support pedestal 4 is hard, an operator who inserts the contact pin 5c into the guide hole 4a or a mechanism that inserts the contact pin 5c into the guide hole 4a has a resistance. Receive.
If the contact pin 5c is forcibly inserted into the guide hole 4a with a force that overcomes this resistance, either the support base 4 or the contact pin 5c may be broken. Therefore,
The worker or the mechanical part having received the resistance is
The insertion of the contact pin 5c into the guide hole 4a is interrupted because the position of the contact pin 5c is determined to be misaligned with respect to the guide hole 4a. Then, after the position of the contact pin 5c and the guide hole 4a are re-aligned, the guide hole 4a of the contact pin 5c is
By reinserting the contact pin 5c, the contact pin 5c is guided and inserted into the elastic through-hole 3b of the buffer pedestal 3 via the guide hole 4a of the rigid support pedestal 4, so that the contact pin 5c is erroneously inserted. Also, it is possible to prevent poor contact between the lead wire 1d and the contact pin 5c.

The support base 4 is provided with a contact pin 5c.
By stopping the relative movement between the pedestal 2 and the wiring board 5 combined with the light source 1 when the base reaches the upper surface of the substrate 5a or the upper surface of the board 5a, the assembly of the light source device for a game machine of the form shown in FIG. Complete. In this state, the lead wire 1d of the light source 1 is sandwiched between the hole wall surface of the guide hole 4a of the support pedestal 4 and the hole wall surface of the through hole 3b of the buffer pedestal 3 and the outer peripheral surface of the contact pin 5c. Since the connection is established, when power is supplied to the wiring board 5, the power can turn on the filament 1b via the plurality of wires 5b, the contact pins 5c, and the lead wires 1d of the wiring board 5.

Further, since the contact pins 5c are inserted into the through holes 3b while expanding the through holes 3b of the buffer pedestal 3 outward, the buffer pedestals 3 around the through holes 3b hold the contact pins 5c by their own restoring elasticity. By having, the assembled form of the light source 1, the pedestal 2, and the wiring board 5 is stabilized.

The bottom of the light source 1 is provided in the housing 3 of the buffer base 3.
a, the posture of the light source 1 is stabilized.

The light source device for a game machine emits light from functional components such as a side lamp, a lamp windmill, a center accessory, a stop lamp, a prize ball lamp, a top lamp, and a plate set of a game machine such as a pachinko machine. In a mode in which the display unit is assembled so as to irradiate light, a ball during a game collides with a functional component. Therefore, even when the light source device for a game machine receives an impact, the wiring board 5 can be used. The shock transmitted to the side of the light source 1 is absorbed by the buffer pedestal 3, so that the long service life of the filament 1b can be extended. Moreover, the long service life of the filament 1b can be further improved by the stability of the form in which the light source 1, the pedestal 2, and the wiring board 5 are assembled and the stability of the posture of the light source 1.

FIG. 4 shows a cross section of the pedestal 2 of the second embodiment cut in the vertical direction. The separately formed buffer pedestal 3 and support pedestal 4 are separated by an adhesive before the pedestal 2 is put on the light source 1. 6, the workability of inserting the lead wire 1d of the light source 1 into the hole formed by the through hole 3b and the guide hole 4a of the pedestal 2 can be improved.

FIG. 5 shows a cross section of the pedestal 2 of the third embodiment cut in the vertical direction. The buffer pedestal 3 and the support pedestal 4 before the light source 1 is put on the pedestal 2 are integrated by molding. The bonding operation is omitted. In this case, one of the buffer pedestal 3 and the support pedestal 4 is molded in advance, and this molded product is stored in the product molding space of the other molding die, and then the molding material is supplied to the product molding space of the other molding die. The buffer base 3 and the support base 4 are integrated with each other, or the hardness of the buffer base 3 and the support base 4 are changed by changing the hardness of the base 2 according to molding conditions. What should I do?

FIG. 6 shows a section of the support pedestal 4 of the fourth embodiment cut in the vertical direction. The diameter of the lower end surface of the guide hole 4a of the support pedestal 4 gradually decreases from the bottom to the top. By forming it as a mortar-shaped inclined surface 4b, the contact pin 5c can be easily inserted into the hole of the pedestal 2.
