[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a control device using slide-type electronic components used for controlling audio equipment, air conditioning equipment for automobiles, and the like.
[0002]
[Prior art]

[0004]
In the figure, reference numeral 1 denotes a consumer-use slide-type variable resistor, which is mounted on a printed circuit board 3 that forms a control circuit of an air conditioning control device together with other electronic components 2. Reference numeral 4 denotes a box-shaped case of an air-conditioning control apparatus having an opening on the rear surface. The printed circuit board 3 is mounted from the opening on the rear surface of the case 4, and the tip of the drive lever 1A of the slide-type variable resistor 1 is the case 4 Is slidably penetrated through a linear opening 4A provided on the front surface of the, and an operation knob 5 is attached to the tip of the drive lever 1A of the slide type variable resistor 1.
[0005]
Next, the operation | movement by sliding operation of the operation knob 5 of this air-conditioning control apparatus is demonstrated.
[0006]
When the operation knob 5 is slid, the sliding body (1) formed integrally with the drive lever 1A of the slide type variable resistor 1 is accompanied by the moderation by the moderation portion formed in the slide type variable resistor 1 by the drive lever 1A. (Not shown) slides in conjunction with each other, the output resistance value changes, and the control circuit of the printed circuit board 3 connected to the slide type variable resistor 1 controls the air conditioning control device of the automobile.
[0007]
[Problems to be solved by the invention]
However, control devices using slide-type electronic components used in the above-mentioned automotive air conditioning control devices and audio equipment are becoming more modest depending on the operating force (feeling of weight) and the operating range as the devices are becoming more sophisticated. It is required to change the size, and as a countermeasure for these, instead of the commonly used consumer-use variable slide resistor 1 with a light operating force, a dedicated slide-type variable having a dedicated operating force and moderation is used. Resistor 6 was newly manufactured and attached to cope with it.
[0008]
However, as shown in FIG. 9B, when the mounting position of the printed circuit board 3 to the case 4 of the air conditioning control device cannot be brought close to the front part of the case 4 due to the height restriction of the other electronic components 2. When the operating force (weight feeling) and moderation feeling are increased by the slide type variable resistor 1, the operating force of the sliding body formed integrally with the driving lever 1A of the slide type variable resistor 1 is increased. The torsional moment generated between the front end of the operation knob 5 and the force of pressing the operation knob 5 is increased, and there is a problem that a feeling of twisting occurs and the operation feeling is not smooth.
[0009]
In order to prevent this, as shown in FIG. 10, it is necessary to divide and attach the printed board 3 in order to bring the slide type variable resistor 6 to the front surface of the case 4, which is disadvantageous in terms of assembly and price. It had become something.
[0010]
In the present invention, a control device using such a slide type electronic component can be used for a textured operating force (feeling of weight) and various moderation conditions by using a low-cost consumer-use variable resistor for general use. Another object of the present invention is to provide a control device using a slide-type electronic component that can be operated smoothly.
