Abstract

A camera having a device for feeding a film, includes a driving unit for generating driving force, a first unit to be driven for feeding the film in a first direction, a second unit to be driven for feeding the film in a second direction which is different from the first direction, and a portion to be driven always engaged with the driving unit, a shaft unit being angularly moved by the driving unit, a driving portion always engaged with the first unit to be driven for moving the shaft unit while angularly moving the shaft unit in an axial direction of the shaft unit when the shaft unit is angularly moved by the driving unit, and an engagement portion for being engaged with the second unit to be driven.

Claims7

Dependent claims

A driving-force transmission mechanism for a camera, comprising:

a single rotative driving source capable of being rotated in a first and second opposing direction for respectively rotating normally and reversely;
a lens-frame including a photographing lens;
a lens-frame driving gear mechanism for moving said lens frame forwardly and rearwardly along an optical axis;
a film driving gear mechanism for winding and rewinding a film;
a planetary gear mechanism for selectively transmitting driving force of said rotative driving source to one of said lens-frame driving gear mechanism and said film driving gear mechanism;
first disengagement means for being engaged with and disengaged from said planetary gear mechanism in interlocking arrangement with operation of said lens-frame driving gear mechanism to change over normal and reverse driving of said lens-frame driving gear mechanism and said planetary gear mechanism;
and
second disengagement means for being engaged with and disengaged from said planetary gear mechanism in interlocking arrangement with operation of said film driving gear mechanism to change over normal and reverse driving of said film driving gear mechanism and said planetary gear mechanism.
