る。 Variable resistors are used in radios and other electronic equipment to adjust the volume, sound quality, balance, contrast, etc. independently from the front of the panel. Various methods have already been devised in which a plurality of variable resistors are stacked in the depth direction and fixed to each other, and each variable resistor is operated independently using an outer shaft and an inner shaft arranged concentrically.

が必要となり製造原価の上昇を伴うことに起因す
る。 From the viewpoint of miniaturization and resource saving of recent electronic devices,
There is a strong demand to reduce not only the space in front of the installation but also the space in the depth direction. Conventionally, various ideas have been announced in which two or more resistance elements are arranged concentrically on the same board for the purpose of providing a variable resistor with a small depth. The elements are adjusted at the same time, and there are currently almost no ideas for adjusting them separately using two concentric axes. The reason for this is that a complicated mechanism is required to increase the rotation-stopping strength of the inner shaft to a level that can withstand practical use, resulting in an increase in manufacturing costs.
本考案はこれらの問題点に鑑み、奥行が小さ

に耐える構造となつている。 Figure 1 shows an example of a conventional concentric two-axis variable resistor. As shown in the figure, the outer shaft 4, which is stacked and fixed one after the other and is rotatably fitted into a bearing 3 fixed to the front stage variable resistor 1, is a slider receiver equipped with a slider 6 that slides against the resistor 5. It rotates together with the table 7, and an appropriately adjusted output is taken out from the terminal 9 via the collector 8. Both ends of the resistor 5 are connected to external terminals (not shown) by a known method. The inner shaft 10 rotatably fitted into the outer shaft 4 reaches the inside of the rear-stage variable resistor 2, and the slider 12 provided on the slider holder 11 fixed to the inner shaft 10 moves into the resistor 13. According to the rotation of the inner shaft 10, an appropriately adjusted output can be taken out from the terminal 15 via the collector 14. Both ends of the resistor 13 are connected to external terminals (not shown) by a known method. At both ends of the rotation range of the outer shaft 4 and inner shaft 10, projections 16 and 17 provided on parts of the slider pedestals 7 and 11 fixed to the respective shafts are connected to stoppers 18 provided on the case of the pre-stage resistor 1, respectively. It also comes into contact with a stopper 19 provided on the case of the rear-stage resistor 2, and has a structure that can sufficiently withstand the torque applied to the outer shaft 4 and the inner shaft 10.

The shaft is rotatably held, and an outer shaft slider is fixed to the pedestal of the outer shaft that rotates within the metal case,
An insulating slider pedestal is provided within the concave portion of the pedestal of the outer shaft, which penetrates the pipe shaft of the outer shaft and rotatably fits therein, and rotates with the inner shaft. A shaft slider is fixed, and two sets of conductors and resistors, on which the sliders of the inner and outer shafts slide in concentric circles on the board, are appropriately connected to terminals fixed to the board, and the inner shaft is Furthermore, a stopper plate made of a metal plate extends through the substrate and the back plate, and its end part rotates in contact with a stop protrusion in a stopper recess provided on the surface of the back plate, thereby regulating the rotation angle of the inner shaft. Concentric 2-axis variable resistor with fixed. (2) The concentric twin shafts according to claim 1 of the utility model registration claim, in which a protrusion provided at the end of the inner shaft is rotatably fitted into a shaft support hole provided at a corresponding position on the mounting plate. Variable resistor. (3) The concentric two-axis variable resistor according to claim 1 of the utility model registration, in which the slider pedestal and the inner shaft are integrally molded from synthetic resin.
