Abstract: An electrical connector having an electrical plug (102) to be plugged into an electrical receptacle (130). The electrical plug (102) includes an electrically insulative plate-like substrate and a plurality of first electrical contacts (118) formed in parallel on at least a side surface at one end of the substrate for a predetermined length from the one end. The plug further includes a shielding part (126) formed of an electrical conductor which substantially shields all of the substrate in a position nearer an end other than the one end having the electrical contacts (118). The electrical receptacle includes an electrically insulative receiving member (138) forming at least part of a recess in which the substrate of the plug is inserted. A plurality of second electrical contacts (142) are arranged in the receiving member (138) so as to contact the plurality of contacts in the plug whenever the substrate of the plug is inserted into the recess.

Abstract: A stereoscopic endoscope including an objective lens system for forming an image of an object which objective lens system is arranged at the front end of an inserting section and has a single optical axis; an image transmission device coaxially arranged with the objective lens system and adapted to transmit the image formed by the objective lens system; a pupil dividing device for dividing the image transmitted through the objective lens system and the image transmission device so as to obtain left and right images of the object; an image sensing device for picking up the left and right images obtained by the pupil dividing device; a first support structure containing at least the objective lens system; and a second support structure containing at least the pupil dividing device and the image sensing device, wherein the first and second support structures are rotatable relative to each other around an axis extending along the longitudinal dimension of the endoscope.

Abstract: A three-dimensional vision endoscopic apparatus according to the present invention comprises a pair of optical systems for transmitting an image of a subject as two subject images having a parallax between them, a pair of imaging devices for picking up subject images transmitted by the optical systems, at least one visual field mask, a display unit for displaying the two subject images alternately or concurrently, an adjusting mechanism for adjusting the position of one or both of the imaging devices so that the display images will become consistent on the screen of the display unit, and an adjusting mechanism for adjusting the relative position of the visual field mask.

Abstract: An endoscope light source apparatus which can feed an illuminating light adapted to a scope provided with a frame sequential type imaging device, a scope provided with a color mosaic type imaging device and a fiber scope has a light source lamp which can emit the illuminating light. A filter which can transmit the illuminating light is interposed in the light path connecting the light source lamp with the entrance end surface of a light guide capable of feeding the illuminating light to the scope and is provided within a cassette which is inserted through an inserting aperture provided on a housing containing the light source apparatus.

Abstract: This endoscope light source apparatus can feed illuminating lights to a scope provided with a frame sequential type imaging device, a scope provided with a color mosaic type imaging device and a fiber scope. This endoscope light source apparatus has a frame sequential light source part which can output a plurality of color lights and a white light source part which can output a white light. This frame sequential light source part has a filter which can output a plurality of color lights.

Abstract: The endoscope light source apparatus of this invention has a light source for emitting a white color light as an illuminating light and a connecting part connectable with the light guide of the endoscope. Reflecting members are movably provided in the light path connecting the light source and the connecting part, and switch the light path between a light path through which the illuminating light adapted to an endoscope provided with a frame sequential type imaging device can be made to enter a filter which can sequentially transmit it and a light path which can avoid the filter.

Abstract: A system comprising a frame sequential type color imaging device, a color imaging device provided with a color filter, an illuminating light outputting device which can output illuminating lights corresponding to these different color imaging devices, a signal processing device processing the signals corresponding to the respective color imaging devices and a color monitor displaying the processed color video signals so that any color imaging device can be used.

Abstract: A film cassette includes a cassette main body with a film supply portion and a film take-up portion, a spool rotatably arranged at said film take-up portion of the cassette main body, and bearings arranged at the film take-up portion for rotatably supporting the spool. The spool comprises an outer cylinder around which a film is wound, an inner cylinder which is slidable in an axial direction relative to the outer cylinder and which is rotatable with the outer cylinder, and a compression spring, one end of which is engaged with the outer cylinder and the other end of which is engaged with the inner cylinder and biasing and moving the outer and inner cylinders relative to each other in the axial direction.

Abstract: A film cassette includes a first cylindrical body forming a film supply section, a second cylindrical body forming a film take-up section, and a coupling section extending between the first and second cylindrical bodies and connected at both ends to the two cylindrical bodies thereby integrally coupling the cylindrical bodies. The coupling section has an outer face continuous with the outer peripheral surfaces of the first and second cylindrical bodies. First cylindrical body includes a ridge protruding from the outer peripheral surface thereof, to which is applied an urging force to rock the film cassette around that cylindrical body with the ridge thereon.

Abstract: An automatic focusing apparatus for a camera comprises a first focusing optical system with a half mirror transmitting light from a subject, a second focusing optical system with a mirror to lead another light from the subject to the half mirror and a single focusing element for receiving said different lights thereby focusing detection.

Abstract: An exposure indicator for a camera having an electrical shutter capable of taking pictures under both automatic exposure and manual exposure.
