Abstract: A camera includes a cover for opening and closing a film chamber, and a lock mechanism that is operable in a first and second modes in the first mode, the lock mechanism inhibits the cover from opening. In the second mode, the lock mechanism allows the cover to open. The first mode starts when the film spool is rotated in a winding direction and continues until the film spool is rotated in a rewinding direction. The second mode starts when the film spool is rotated in the rewinding direction continued until the film spool is rotated in the winding direction.

Abstract: A camera having an electronic flash equipment includes a body case having a generally rectangular shape in a front elevational view. A photographing lens is provided near the center of a front surface of the body case. A strobe mounting arm is pivoted, at a base end thereof, to an upper portion of the body case, to be rotatable between inoperative and operative positions. When the strobe mounting arm is in the inoperative position the strobe mounting arm extends along and on the body case. When the strobe mounting arm is in the operative position, a front end portion of the strobe mounting arm projects outward from a lateral edge of the body case adjacent to the pivotal connection of the body case to the strobe mounting arm. The strobe mounting arm is provided on the front end portion with a strobe light emitter which faces toward a subject to be photographed when the strobe mounting arm is in the operative position.

Abstract: A parallax compensation system in a camera finder includes a mirror surface mounted to a mounting member. The mounting member is rotatably mounted to a mounting frame having protrusions about which the mounting member rotates such that the mounting member is rotatable about an axis defined on the mirror surface. A cam mechanism is rotatably mounted on a top surface of the mounting frame for regulation of the mounting member to have a predetermined position. An urging member biases the mounting member against the cam mechanism, so that when the cam mechanism is rotated, the mounting member is rotated about its axis according to a cam surface of the cam mechanism. The mounting member is rotated about the axis of the mirror surface to change an optical axis of the same to compensate for parallax.

Abstract: An adaptor supports a patrone having a small diameter so as to adapt the patrone for use in a patrone chamber of a camera. The adaptor includes a supporting portion for supporting the patrone of small diameter and a positioning portion that engages with at least one portion of the patrone chamber.

Abstract: A camera is provided having a view finder that includes a field frame varying mechanism for varying the ratio length between the longitudinal and lateral sides of a field of frame of the finder. An aperture varying mechanism is provided for varying the physical size of an aperture for exposure of a film in accordance with the ratio of field frame side lengths.

Abstract: A remotely controllable camera system has a photodetector mounted in a camera housing and facing a front panel thereof. The photodetector detects an external optical command signal beam applied thereto through the front panel. The camera system also has an optical fiber for guiding an external optical command signal beam applied through a rear panel of the camera housing toward the photodetector. The external optical command signal beam is transmitted from an infrared remote controller which may be positioned in front of or behind the camera. The camera has an electrically controllable shutter that can be released in response to the external optical command signal beam detected by the photodetector.

Abstract: A sealed case comprises a communication hole in an outer wall of the case for communicating the inside and outside of the case, and the communication hole is closed by a seal element comprising a highly restorable elastic element having airtightness.

Abstract: In a camera adapted to be sealed against water, a camera having a reciprocating lens barrel, a member for detecting water around the camera, and for controlling the lens barrel, so that the lens barrel will not be moved when water is detected by the detecting member. In another embodiment the camera is provided with a member for detecting water at a certain hydraulic pressure and a member for indicating an alarm when water at such a pressure is detected. Thus, by immobilizing the lens barrel, it is possible to prevent water damage to the camera that might result if the camera were submerged and the lens barrel moved.
