摘要： A camera for setting the aspect ratio of a photographic image plane and recording information of the set aspect ratio has a full-size frame defining a full-size finder image plane corresponding to a photographing image plane, a vertical mask for vertical trimming of the finder image plane, a lateral mask for lateral trimming of the finder image plane, a shaft supporting the masks, and a camshaft with a cam groove engaged by each of the masks. The masks are moved along the shaft by rotating the camshaft. The visual field range of the finder image plane is changed among a plurality of states corresponding to different aspect ratios. The camera finder visual field frame switching mechanism consists of: a vertical mask for vertical trimming, lateral mask for lateral trimming, cam gear having a cam, vertically movable mask operating member, a vertical trimming switch detecting vertical-mask trimming movement, which is aspect ratio information, and a lateral trimming switch detecting lateral-mask trimming movement positional information which is also aspect ratio information. Another embodiment is provided with a vertical mask for vertical trimming of a finder image plane and a lateral mask for lateral trimming of the finder image plane, which, after the vertical mask retreats from a vertical trimming position, moves the lateral mask to a lateral trimming position. After the lateral mask retreats from the lateral trimming position, the vertical mask is moved to the vertical trimming position.

摘要： A camera having: a substantially cylindrical-shaped, rotatable cam, limited to rotate unidirectionally. A drive belt conveys rotation of the rotary member, which rotates due to zooming of lens array, to drive the cam. A viewfinder optical system including a stationary objective lens, two prisms, a stationary eyepiece lens, and two variable-power lenses, when coupled with the cam member, advances or withdraws along the optical-axis during movement. An eyepiece variable-power lens is inserted into the optical path of the viewfinder optical system. A viewfinder panoramic field mask is united with an eyepiece variable-power lens. Upper and lower masks change picture size. A first rack extends in a moving direction of the masks. A second rack extends in a moving direction of the viewfinder panoramic field mask. A panoramic-mode setting gear engages the two racks. A plurality of panoramic-mode parallax compensation marks appear at a trimmed range position within the viewfinder field mask. Normal picture size-mode parallax compensation marks are removed from the field during a high power. A viewfinder objective lens sliding axis pin retained by the objective lens or first prism, guides the two variable-power lenses along the optical axis. One end of a viewfinder lens base retained by the stationary objective lens or first prism, has a ditch restraining rotation of the two variable-power lenses about the viewfinder objective lens sliding axis.

摘要： A camera comprises a fixed lens barrel including a moving lens barrel movable to a collapsed position for non-photography and to a thrust position for photography, and a lens cover capable of pivoting with support shafts, which lie parallel to a plane substantially perpendicular to the optical axis of a photography lens, as a center so as to move to a closed position at which at least part of the face of the photography lens is shielded and to an open position at which the face of the photography lens is exposed. When the lens cover is open, if an external force is applied in a direction in which the lens cover is further opened, the lens cover comes off from the support shafts. The support shafts are formed with two shaft members whose distal portions are formed with tapered surfaces and which are constrained to move in directions in which they are separated from each other. The support shafts are mounted on a member which allows the support shafts to move along the optical axis of the photography lens.

摘要： A camera includes a body drive motor for driving forwardly or backwardly, a first planetary gear mechanism for selecting whether the output from the motor should be transmitted to a zooming device, a prohibition device for prohibiting the rotation of the planetary gear mechanism after the first planetary gear mechanism has completed the selection, a second planetary gear mechanism for selecting whether the output from the first planetary gear mechanism, which was not transmitted to the zooming device, should be transmitted to a winding device, and a third planetary gear mechanism for transmitting the output from the second planetary gear mechanism, which was not transmitted to the winding device, should be transmitted to either the rewinding device or a photographic image-plane size switching device. The planetary gear mechanism is rotated at a low speed so that the output of the first planetary gear mechanism does not exert an influence upon the second planetary gear mechanism when the driving force of the motor is switched from the zooming device to the photographic image-plane size switching device.
