Claims

[Scope of utility model registration request]

(1) A tuning device that includes a tuning mechanism body on a back cover that is detachably attached to the cabinet body, and operates the tuning mechanism body with a knob that is rotatably attached to the top or side surface of the cabinet body. The knob includes a shaft that protrudes into the cabinet main body and has a drive gear formed at an end thereof, and the tuning mechanism main body is detachable from the drive gear of the knob from a radial direction thereof. It includes a synchronization operation shaft that is connected to a driven gear that transmits the rotation to the dial thread, and a holding means that biases and holds the synchronization operation shaft, and the driven gear is connected to the back cover when the camera back is attached or removed. A tuning device selectively meshing with the drive gear in conjunction with the tuning device.

(2) Utility model registration In claim (1), the holding means includes a substrate and a long hole bored in the substrate in the same direction as the attachment/detachment direction of the back cover, into which the tuning operation shaft is inserted. ,
a spring member that is provided on the substrate and presses the tuning operation shaft; the spring member has a pressing force that resists positional fluctuations of the tuning operation shaft; and the pressing force is applied to the axis of the tuning operation shaft. A tuning device characterized in that the tuning device is adapted to be applied from a direction perpendicular to the direction.
