う問題点があった。Conventional Structure and Problems Generally, as shown in Figs. 1 and 2, a dial drive device consists of a rotating body (hereinafter referred to as a drum gear) 1 attached to a rotation adjustment element (hereinafter referred to as a variable capacitor) 4. , a pointer 2, a drum gear 4, and a drive shaft 3 that meshes with the pointer 2. By rotating the drive shaft 3, the position of the pointer 2 is moved, and at the same time, the variable capacitor 4 is rotated and adjusted. In this case, the travel distance of the pointer 20 is determined by the size of the drum gear 1. If the travel distance of the pointer 2 is to be changed, the size of the drum gear 1 must be changed, and there is a problem in that the relative position between the variable capacitor 4 and the drive shaft 3 cannot be set arbitrarily.

指針の走行距離を決めることができるものである。Structure of the Invention The dial drive device of the present invention is composed of a drum gear having a gear on the outer surface attached to a variable capacitor, a drive shaft that meshes with the drum gear, and a pointer that meshes with the drive shaft. By making the gears that mesh with the drum gear independent and changing the pitch of both gears, it is possible to determine the travel distance of the pointer without being restricted by the shape or relative positional relationship of the drum gears.

It consists of a drum gear 7, a pointer 6, and a drive shaft 6 having gears 9A and 9B with different pinches at the parts that mesh with the pointer 6 and the drum gear 7. When the drive shaft is driven to rotate, the drum gear 7 is b (or b')
direction, and at the same time, the pointer 5 moves in the a (or a7) direction. By arbitrarily combining the pitches of the nine gears and the gear 9B, the travel distance of the pointer 50 can be arbitrarily determined without being restricted by the shape of the drum gear 7 (gear radius, etc.).
