However, in all of the above-mentioned prior arts, the substrate of the rotary operation type electric component on which the arc-shaped conductive pattern is formed is perpendicular to the sliding direction of the slide operation type electric component. In order to secure the pattern width of the conductive pattern, the pattern forming surface of the substrate cannot be made too small, so that it becomes a composite operation type electric component having a large diameter portion. It was difficult to reduce the overall size.

Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art and to provide a composite operation type electric component which does not require a large diameter portion and can be easily downsized.

In the composite operation type electric component constructed as described above, when the operation shaft is rotated, the rotatable second slider receiver is not interlocked, but the first slider receiver is rotated. Since the slider provided on the first slider receiver slides on the first conductive pattern formed on the arc-shaped wall surface of the insulating base, it can be operated as a rotary operation type electric component. Also,
When the operating shaft is slid, the first slider receiver spline-coupled does not interlock, but the second slider receiver slides, and the slider provided in the second slider receiver is an insulating base. Since it slides on the second conductive pattern formed on the linear wall surface of the table, it can be operated as a slide operation type electric component. Further, since the arc-shaped wall surface of the insulating base is located around the operation shaft, the first conductive pattern used during the rotating operation can be formed in the small diameter portion while ensuring a necessary pattern width. , Miniaturization becomes easy.

In these figures, reference numeral 1 is a highly rigid operation shaft having a knob 1a at one end, and 2 is a splined connection to the operation shaft 1 and rotates in conjunction with the rotational movement of the operation shaft 1. Reference numeral 1 is a slider receiver, 3 is a first slider which is made of a spring metal plate and is fixed to the outer peripheral surface of the first slider receiver 2, and 4 is opposite to the knob 1a side of the operation shaft 1. Is a second slider receiver rotatably held at the side end, and the second slider receiver 4 does not rotate even if the operation shaft 1 is rotated, but It slides in conjunction with the sliding movement of the shaft 1. Reference numeral 5 denotes a second slider which is made of a spring metal plate and is fixed to the outer peripheral surface of the second slider receiver 4, and 6 denotes the first slider 2 and the second slider receiver 4. A spacer 7 is slidably and rotatably held on the operation shaft 1 between the arch-shaped wall portion 7a facing the first slider bearing 2 and the second slider bearing 4 facing each other. An insulating base 7 having a flat wall portion 7b,
8 is a first conductive pattern formed in an arc shape along the inner peripheral surface of the arched wall portion 7a of the insulating base 7, and 9 is a flat surface of the flat wall portion 7b of the insulating base 7. The second conductive patterns 10 formed in a straight line along the first conductive pattern 8 are integrated with the insulating base 7 by insert molding.
Alternatively, the external lead-out terminal connected to the second conductive pattern 9 is a mounting hole 1 for inserting the operation shaft 1.
1a and a metal frame which has an engagement piece 11b for fitting into the engagement groove 7c of the insulating base 7 and closes the base 7 with a lid, and 12 is a periphery of a mounting hole 11a of the metal frame 11. The retaining ring 13 is attached to the second retaining member 13 and the E ring 13 is provided to prevent the second slider receiver 4 from being displaced relative to the operating shaft 1. That is, the first and second slider receivers 2 and 4 held by the operation shaft 1 are housed in the space covered by the insulating base 7 and the metal frame 11, and the first sliding member The child receiver 2 is arranged at a position facing the inner peripheral surface of the arched wall portion 7a, and the first slider 3 is brought into sliding contact with the first conductive pattern 8, and the second slider receiver is also provided. 4 is arranged at a position facing the flat surface of the flat plate-shaped wall portion 7b, and the second slider 5 is brought into sliding contact with the second conductive pattern 9.

In this embodiment, MID (Molded)
By adopting a known technology called "Interconnection Device", the insulating base 7 is molded by injecting the molten resin while the film having the conductive pattern printed on one side is clamped in the mold, and the insulating base 7 is molded. First and second conductive patterns 8 and 9 are transferred from the film to predetermined positions of the base 7.

In the composite operation type electric component thus constructed, when the operation shaft 1 is rotated by turning the knob 1a, the second slider receiver 4 which is rotatable with respect to the operation shaft 1 is interlocked. However, since the first slider receiver 2 rotates and the first slider 3 fixed to the slider receiver 2 slides on the first conductive pattern 8, the rotary operation type electric It can be operated as a component. When the operating shaft 1 is slid by pushing or pulling the knob 1a, the first slider receiver 2 which is slidable with respect to the operating shaft 1 does not interlock, but the second slider receiver 4 does not move. Since the second slider 5 fixed by sliding on the slider receiver 4 slides on the second conductive pattern 9, it can be operated as a slide operation type electric component. A single arc-shaped conductive pattern 8 used during the rotating operation is provided on the inner peripheral surface of the arch-shaped wall portion 7a located around the operation shaft 1, and the conductive pattern 8 is formed.
Since it is not necessary to increase the inner diameter of the arch-shaped wall portion 7a even if the necessary pattern width is secured, the conventional product in which the arc-shaped conductive pattern is formed on the wall surface standing up to the sliding direction of the operation shaft is used. Compared to this, it is an extremely slim composite operation type electrical component, and its miniaturization is being promoted.

Further, in the composite operation type electric component, the operation shaft 1 having the first and second slider receivers 2 and 4, the spacer 6 and the retaining ring 12 attached thereto is mounted on the metal frame 11 at the time of assembling. Since it can be held as a unit, the assembly is completed only by combining these unitized members and the insulating base 7, and after the assembly, the insulating base 7 and the metal frame 11 maintain dustproofness. Therefore, defective conduction between the sliders 3 and 5 and the conductive patterns 8 and 9 due to adhesion of dust can be prevented in advance. Therefore, there is an advantage that the assemblability is good and the high reliability can be maintained.

The spacer 6 used in the above embodiment is for restricting the slide movement amount of the operating shaft 1. The spacer 6 is the first slider receiver 2 or the second slider. It may be integrated with the receiver 4.

In the above embodiment, the knob 1a is provided at one end of the operation shaft 1 in the longitudinal direction to provide a new type of composite operation type electric component which can perform the push type slide operation and the rotation operation. If the knob protruding in the lateral direction of the operation shaft is configured to be movable in the longitudinal direction and the circumferential direction of the operation shaft, the same operation mode as that of the conventional composite operation type electric component can be realized.
