を任意に設定できないという問題点があつた。Conventional configuration and its problems In general, a dial drive device, as shown in Figs. 1 and 2, 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 2 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.

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. The gears that mesh with each other are made independent,
By changing the pitch of both gears, the travel distance of the pointer can be determined without being restricted by the shape or relative positional relationship of the drum gears.

ができる。 3 and 4 show one embodiment of the present invention, in which a drum gear 7 attached to a variable capacitor 8 and a pointer 5 are shown.
It is composed of a drive shaft 6 having gears 9A and 9B with different pitches at the portions that mesh with the pointer 5 and the drum gear 7, and when the drive shaft b is driven to rotate, the drum gear 7 rotates in the direction b or b'. , simultaneously the pointer 5 moves in the direction a or a'. gear 9
By arbitrarily combining the pitches of the gears 9A and 9B, the travel distance of the pointer 5 can be arbitrarily determined without being restricted by the shape of the drum gear 7 (gear radius, etc.).
