Claims

[Scope of utility model registration request]

(1) At least the intermediate gear of the inner peripheral gear provided at the center of the slider holder of each of the first, second, and third rotary variable resistors arranged on the same axis. The gear of the second variable resistor is a penetrating type, and is set on the outer periphery of the operating shaft passing through the center of the three variable resistors so that it can mesh with and penetrate the inner gear of the second variable resistor. The serrated gear meshes with any one of the gears around the slider holder body of the three variable resistors at a predetermined position by pulling and pushing the operating shaft, and at that position, the operating shaft A multiple variable resistor in which the slider holder is rotated and slid to change the resistance value by rotating the slider holder.

(2) A serration-shaped gear on the outer periphery of the operating shaft is normally urged by a spring to mesh with a gear on the inner periphery of the slider holder of the intermediate second variable resistor, and the operating shaft is moved against the force of the spring. By pulling or pushing, the inner peripheral gear of the first variable resistor or the third variable resistor engages, and when the pulling or pushing force applied to the operation shaft is removed, the force of the spring causes the second variable resistor to engage again. A multiple variable resistor according to claim 1, which is configured to mesh with an inner peripheral gear of a device.

(3) The serration-shaped gears on the outer circumference of the operating shaft are the first and second gears.
Alternatively, a locking mechanism is provided in which a narrow diameter part provided on a part of the operating shaft is clamped by another spring so that it can be securely locked at the position where it meshes with each of the gears around the slider holding body of the third variable resistor. A multiple variable resistor according to claim 1 of the utility model registration claim.
