FOLDING TYPE CAMERA BUILT IN WITH AUTOMATIC FOCUS CONTROLLING MECHANISM

机译:具有自动焦点控制机制的折叠式相机

摘要

PURPOSE:To make the camera easy to carry by forming a distance measuring device consisting of a movable mirror driving part, taking lens driving stopping members, control mechanism, etc. into the construction that it can be folded while maintaining the connection of the respective members in cooperation with a front cover with a hinge as center. CONSTITUTION:When a lock pawl 18 is disengaged from a rack rod 11 by release operation, the rack rod 11 is moved by the force of a spring 14, and a lens 1 is moved by way of a relay lever 13; at the same time a pinion 10 and cam 8 rotate to deflect a mirror 6. Thereby, the distance up to the subject is measured; at the same time a focusing signal is emitted to move an electromagnetic member 15 which in turn causes a pawl member 16 to engage the rack rod 11 thereby stopping the same. When a motor 3 runs to feed the photographing film, the rack rod 11 is pushed back by means of a gear train 4, cam 4', change-over lever 21 and clutch gear 11, and is fixed by the lock pawl 18. Since the distance measuring device may be folded while maintaining the connection by way of the hinge mechanism of the front cover B, it is convenient for carrying.
