Problems solved by technology

[0006] The inventor also believes that setting several motors and other power devices in a single camera will increase the cost, increase the weight of the camera, complicate the structure, and reduce the mean time between failures of the device.
[0007] In the case of using one motor to drive in two directions, although it can reduce the weight and structural complexity, it can be regarded as a logic circuit to control the mechanical energy of a single motor, which is expensive

Abstract

The invention relates to a camera-lens position regulating method and apparatus, and camera thereof. The camera comprises: a lens holding member, a motor providing revolution driving force in a predetermined direction, a geared ring, a cam, a potential applying element of which one end is connected with one of the geared ring and the cam and the other end is connected with a movable object, and a clutch for controlling joint and separation between the geared ring and the cam. According to the invention, using mono-directional driving force of the motor to control bi-directional movement of the driving device can realize at least one of focusing operation, film feeding operation, zooming operation, lens retracting operation and shuttering operation, with a cheap structure and without expensive driving source.

Description

[0001] This application is a divisional application based on the patent application whose filing date is May 5, 1999, application number is 99106325.2, and the title of the invention is "lens position adjustment method and device and camera". technical field [0002] The present invention relates to a lens position adjustment method, a lens position adjustment device, and a camera. More specifically, it relates to a camera that is provided with a drive mechanism and a lens position control mechanism that use only one motor to realize several actions. Driving force, the above-mentioned lens position control mechanism can carry out two-way control to the lens position or other movable devices. Background technique [0003] Generally, in a camera, a driving force of a driving source such as a motor is transmitted to camera components to perform various actions. For example, in a single-focus camera, the actions (1) film feeding, (2) focusing, and (3) shutter release are perform...
