摘要： PURPOSE:To facilitate the change of power transmission route by providing an energizing means between an engaging hook and a subhook so that the subhook is displaced in the direction engaged with a switch lever, and detecting the specified torque at the end of winding up a film. CONSTITUTION:When the film is completely wound up with the planetary gear 22 of a switching planetary clutch mechanism 20 engaged with a winding gear 24, a torque detecting lever 33 detects the specified torque to release the engaging hook 40. Rotational force is transmitted to the switch lever by means of a motor; the switch lever 26 is not held by any members when the engaging hook 40 is released, and consequently it receives rotational force to turn itself. Because of the turning of the switch lever 24, the planetary gear 22 of the switching planetary clutch mechanism 20 is engaged with a rewinding gear 25, and then rotational force of the motor is transmitted to a rewinding gear train to rewind the film. In order to switch the engagement of the planetary gear from the winding gear to the rewinding gear, the switch lever 26 is turned up to the original position. Thus, transmission route can be easily switched.

摘要： PURPOSE:To prevent a planetary gear from biting to a gear to be moved and escaping from it by providing the planet gear which rotates once around a sun gear, the gear to be moved on a tele or wide side which meshes with the planetary gear and a stopper mechanism for regulating the meshing position of the planet gear in a focal distance varying mechanism. CONSTITUTION:A planet clutch mechanism is provided for switching tele and wide of the focal distance varying mechanism. The planetary gear 120 of the planetary clutch mechanism can rotate once around the outer periphery of the sun gear 95A and it is arranged so as to mesh with the gear to be moved of a gear train on the tele side and a gear train on the wide side. The stopper mechanisms 128A and 128B are provided, which turn by interlocking with the planetary gear 120 and a knob provided on an external part and regulate the meshing position of the planet gear with the gear to be moved of the gear train on the tele side or the gear train on the wide side. Therefore, the planetary gear 120 of the planetary clutch mechanism 120 can rotate around the outer periphery of the sun gear 95A in a tele-operation or a wide-operation. Thus, the positioning relation between the planet gear 120 and the gear to be moved can be made neutral, neither biting nor escaping.

摘要： PURPOSE:To facilitate initial adjustment for focal length by moving lens groups in the direction of the optical axis only by rotating a focus adjusting pin. CONSTITUTION:This mechanism consists of a driving member 22 which is associated operatively with the forward/backward movement of a moving lens barrel 4 and the focus adjusting pin 7 having a support pin 7e and an eccentric pin 7a whose center is eccentric with the center of the support pin 7e. When the support pin 7e which is associated with the driving member 22 is rotated, the eccentric pin 7a swivels around the center of the support pin 7e. The moving lens 2 is associated with the eccentric pin 7a, so the optical-axis directional position of the moving lens 2 changes with the coupling position between the eccentric pin 7a and moving lens 2. Consequently, the focal length is adjusted initially with ease.

摘要： PURPOSE:To execute the operation of a film and the operation for a focusing by detecting specified torque at the time of completing the taking-up of all the film, linking a 1st planetary clutch mechanism with a film rewinding mechanism and changing the focal distance variably by means of a 2nd planetary clutch. CONSTITUTION:With the normal rotation of a motor 10, the planetary gear 30 of a 1st planet clutch mechanism is made to mesh with the gear 32 of a film taking-up mechanism. And when the rotation is prevented by a film end, the gear 30 is made to mesh with the gear 34 of the rewinding mechanism with the rotational force of the motor 10 and that of an arm. When the engagement of a pin 40 with an arm 28 by operating an engaging lever 38 from the external part of a camera is released, manual taking-up is executed with a motor 10. And when the motor 10 is made to inversely rotate, the planetary gear 74 of a 2nd planetary clutch mechanism is made to mesh with the gear 80 of a focusing switching mechanism, so that a lens barrel is drawn out and the focusing is altered.

摘要： PURPOSE:To take-up and rewind a film with the normal rotation of a motor and to execute other works with reverse rotation, by providing a torque detection mechanism for detecting a specified torque at the time of completing the taking-up of all the film and making a planetary clutch mechanism link with a film rewinding mechanism. CONSTITUTION:By the eneragizing force of the spring 44 of an engaging lever 38 and the spring 48 of the torque detection lever 46, the planetary gear 30 meshes with the gear 32 of a film taking-up mechanism and the film which is not shown in a drawing is taken up to a spool 76. Next, at the time of completing the take-up of the film, the spool 76 can not be rotated. When a motor 10 tries to rotate in such a state, the torque detection lever 46 turns counterclockwise and the gear 30 is linked with the rewinding mechanism and the film is rewound into a cartridge. When a zoom knob 136A is held on a teleposition, the rotational force from the motor 10 transmits the clockwise rotating force to the gear 32. Then a lens barrel 120 can be contained.

摘要： PURPOSE:To range-find in a wide range and to almost surely range-find even when an object is dislocated from the central part of a finder by disposing plural range-finding optical systems horizontally in a line and obliquing both the longitudinal direction of a projecting part in the range-finding optical system and detecting direction of the photodetector in a light receiving part. CONSTITUTION:The range-finding system constituted with projecting part 13 and light receiving part 14 is disposed horizontally in a line while pinching a finder 12 in the projecting part 13, a projecting element 13a is obliquely disposed so that the object is irradiated obliquely with the light; in the light receiving part 14, the photodetector 14a is disposed so that it receives the light reflected by the object and detecting direction is oblique. Thus, when the camera is held horizontally or perpendicularly, the light is obliquely projected to the object in the form of a slit or plural dots. Since the detecting direction of the light receiving part is oblique, the part receives surely the light which is obliquely projected to the object and reflected by it. The object is detected in a wide range of all directions; thus, information on range for accurate range-finding is obtained in photographing.

摘要： PURPOSE:To shoot a night view by exposing for a specific long time even if the longest exposing time is limited with an automatic exposure control by providing a release control means for releasing a shutter in a specific exposing time for night view shooting in preference to be exposing time under the automatic exposure control when an external world is darker than a specific luminance at the time of requiring a distant view shooting. CONSTITUTION:The title device is provided with a brightness discrimination means for discriminating whether or not the external world is darker than the specific luminance and the release control means for releasing the shutter in the specific exposing time for night view shooting in preference to the exposing time under the automatic exposure control when the external world is darker than the specific luminance at the time of requiring the distant view shooting. Namely, since a photographic lens is set so that infinity is an optimum focusing distance and a specific long exposing time is set by requiring the distant view shooting when the external world is darker than the specific luminance, the night view shooting can be accomplished even if the longest exposing time is limited with the automatic exposure control.

摘要： PURPOSE:To easily take-up and rewind a film with the rotation of a motor in the same direction, by detecting specified torque at the time of completing the taking-up of all the film and making a planetary clutch mechanism link with a film rewinding mechanism from a film take-up mechanism. CONSTITUTION:When the motor 10 normally rotates (clockwise rotation) in a state where the planetary gear 30 of a planetary clutchmechanism meshes with the gear 32 of the film take-up mechanism, the rotational force is transmitted to the take-up mechanism and a spool 76 rotates counterclockwise so as to take up the film to the spool 76. And when the full length of the film is taken up to the spool 76 and the film end is detected, a torque detecting lever 46 is actuated so that the film can be rewound into a cartridge in the normal rotational direction of the motor 10. Since the specified torque is detected and the planetary clutch mechanism is made to link with the rewinding mechanism from the film take-up, mechanism, the wind-taking-up and the rewinding of the film can be executed with the rotation of the motor in the same direction and a control circuit can be simplified.
