SOLUTION: The rotating barrel 3 is set so that it can be moved in the optical axis direction with respect to a fixed barrel 2 and energized backward in the optical axis direction by a coil spring 20. Then, a cylindrical cam 21 is formed around the inside wall surface of the flange part 2B of the barrel 2 and the cam pin 3B of the barrel 3 is made to abut on the cam surface of the cam 21. When the barrel 3 is rotated, it is moved back and forth in the optical axis direction with respect to the barrel 2 according to the shape of the cam surface of the cam 21. Besides, the first and the second moving barrels 4 and 5 are moved in the optical axis direction so as to execute the focusing operation. Then, the power variable operation and the focusing operation are simultaneously executed by the rotating operation of the barrel 3 by one driving source.

摘要： PURPOSE:To provide a finder switching mechanism by which only a field frame in accordance with a photographing mode is allowed to appear and which does not prevent a camera from being miniaturized by forming a normal field frame and a panoramic field frame in a state where they are superposed on one field frame plate of a lighting finder and shielding the unnecessary field frame from light in accordance with the photographing mode. CONSTITUTION:A light shielding plate for a field frame 10 which can freely slide is provided between a lighting window 12 and the field frame plate 8 on which a normal field frame mark 14 and a panoramic field frame mark 16 are superposed to be formed, and light shielding parts 10a-10d are formed on the plate 10. The light shielding parts 10a-10d are formed at positions where either the mark 14 or the mark 16 is shielded from the light by the light shielding parts 10a-10d when the plate 10 slides. By allowing the sliding of the plate 10 to interlock with the operation of a switching knob 30 for switching the photographing mode, the mark 16 is shielded from the light in a normal photographing mode and the mark 14 is shielded from the light in a panoramic photographing mode.

摘要： PURPOSE:To display only either of field frames for first size or second size, according to the photographing of the first size or that of the second size. CONSTITUTION:In this lighting type bright frame finder, the field frames for full size and panoramic size are changed over according to the photographing of the full size or that of the panoramic size. In other words, two field frames for the full size and the panoramic size 14A and 14B, are prepared. When the photographing of the full size is executed, the field frame for the full size is inserted into a prescribed location and when the photographing of the panoramic size is executed, the field frame for the panoramic size is inserted into the prescribed location. On the other hand, a liquid crystal display unit capable of displaying the field frames for the full size and panoramic size can be used insted of the two field frames. Thus, only the field frame can be displayed according to the photographing of the full size or that of the panoramic size.

摘要： PURPOSE:To facilitate the check of focusing of a fully automatic camera by starting a test mode and setting a photographic lens at a specified position when a back cover opening signal and a test requiring signal are given and the release of shutter is performed and keeping a shutter in an open state for a specified time as long as the release of shutter is not performed again. CONSTITUTION:When the release of shutter is performed in a state where the back cover is opened and a test mode terminal 3 is grounded, the photographic lens is set at the specified position regardless of AF control and AE control. The shutter 14 is kept in the open state for the specified time as long as the release of shutter is not performed again and a light beam is made incident on a focusing surface through the photographic lens and the check of focusing can be performed. Thus, the check of focusing, etc., of the fully automatic camera can be facilitated.

摘要： PURPOSE:To prevent optical backlash by stopping a motor at the time of completing the retreat of a photographic lens, connecting a zoom changeover switch in neutral and driving the motor for a short time again in the case that optical hysteresis occurs at the time of retreating the photographic lens to a wide side. CONSTITUTION:The title camera is provided with zooming devices 51 and 52 which switch a power transmitting path by using clutch means 50b and 50c and make the photographic lens 54 advance and retreat in virtue of the rotation in the same direction of one motor 30 to change a focal distance. When the changeover switch 66 for moving the lens 54 in a direction where the optical hysteresis occurs is disconnected in the case of making the photographic lens 54 advance or retreat in virtue of the rotation of the motor 30, a contact disconnection signal is transmitted and the rotation of the motor 30 is stopped with the contact disconnection signal. Thereafter, the motor 30 is allowed to rotate for a specified time in the case of connecting the changeover switch 66 to a neutral contact. Thus, the backlash caused by the optical hysteresis can be surely eliminated with a simple means.

摘要： PURPOSE:To prevent a lens barrel and inner parts from being damaged or deformed by interlocking a finder variable power mechanism with a finder interlocking member dislocated in response to the advancing and retreating of the lens barrel and interlocking an encoder with an encoder interlocking member. CONSTITUTION:The variable power mechanism of a finder 40 is interlocked with the finder interlocking member 23 dislocated in response to the advancing and retreating of the lens barrel 4, and the encoder 20 is interlocked with the encoder interlocking member 19 dislocated in response to the advancing and retreating of the lens barrel 4. When a motor rotates, the lens barrel 4 moves in the direction of an optical axis to change a focal distance. In response to the advancing and retreating of the lens barrel 4, the magnification of the finder 40 changes. Simultaneously the encoder 20 detects the position of the lens barrel 4, and photographing is performed at exposure corresponding to said focal distance. If external force is applied to the lens barrel intentionally or accidentally, it moves the lens barrel 4 in the direction of the optical axis, and by interlocking the move, the finder 40 and the encoder 20 operate. Thus damages of the lens barrel 40 or inner parts can be prevented.

摘要： PROBLEM TO BE SOLVED: To enable sure reading processing for a data disk, even if a cartridge film provided with the data disk is loaded, after the opening/closing operations of a cartridge cover for a camera are executed without loading the cartridge film. SOLUTION: The camera is equipped with a detecting switch 40 for detecting the presence of the loading of the cartridge film CFL and a spool key 34 connected to the spool of an unexposed cartridge film CFL at a fixed angle position, when this unexposed cartridge film CFL is loaded, in a cartridge loading chamber 32. This chamber 32 is covered/uncovered with the cartridge cover 30. When the cartridge cover 30 is opened/closed in a state where the cartridge film is not loaded in the chamber 32, a microprocessor in a camera body 2 decides the unloaded state, based on the output of the detecting switch 40 and the spool key is kept stopping at a different fixed angle position from the above-mentioned fixed angle position.
