摘要： A motion picture camera which can use a cartridge for film having a sound track includes sound recording means and a mechanism which actuates and releases the sound recording means to an operative state and to an inoperative state, respectively, in response to an actuation and a release of a shutter release member. All such parts which are needed to engage a film are arranged in a cartridge chamber defined in the camera housing so that the operator enables to readily insert a cartridge into the chamber so long as the sound recording means are set to their inoperative position.In another phase of the present invention, in order to insure proper sound effect, a motion picture camera of the type described and having a manually switchable picture image frame frequency control device having a plurality of switched positions is provided with locking means positioned adjacent the control device upon engagement therewith to lock the control device in a particular position for image-sound synchronous recording operation, and operatively associated with one of the switches of the circuit of the sound recording means upon engagement with the control device to close the switch.

摘要： A photographic camera in which a film cartridge, housing a photographing film having a recording belt capable of recording sound signal, can be loaded, wherein for the purpose of effecting the recording of sound signal simultaneously with photographing a sound signal recording head and a constant speed film running mechanism are provided at the sound signal recording part being separated from an intermittent film transport mechanism for running the above mentioned film with a constant speed. The above mentioned sound signal recording head can take an active state wherein sound signal recording on the above mentioned sound signal recording belt is possible and an inactive state wherein said recording is impossible, selectively, and the shifting from said inactive state to the active state is done in an association with the action of the locking means of the cover of a chamber for the above mentioned film cartridge so that simultaneous sound recording and photographing can be done immediately after the camera cover is locked.

摘要： An information displaying apparatus includes, bundles of optical fibers with their ends coplanar and disposed in line. A movable masking member imposes information on the light input to the fiber array. At the output end, information markings are selectively illuminated or otherwise luminously designated to display various kinds of information. Displaying means may be disposed within a view finder or on the outer casing of a camera. An artificial light source operates to provide light through the masking member and may be switched on manually or automatically when needed for information display.

摘要： A film gate formed as one integral unit by molding a black synthetic resin material includes a film gate portion, a recess for receiving a film driving member for reciprocal movement therein, film guide walls, positioning means and protective walls to protect resilient side pressure members from damage from careless loading of a film magazine. The positioning means may be used as reference position to secure the gate unit to a fixed frame of a motion picture apparatus. The side pressure members are formed as extensions of a holding member that also applies resilient force to the film driving member near the root of its film-advancing pawl.

摘要： A zoom lens structure for use with an optical instrument comprises a zooming optical system movable along the optical axis thereof and including a magnifying system and a correcting system; support frames for holding the zooming optical system; a plurality of guide shafts fitted in the support frames of the zooming optical system to cause sliding of the support frames; a frame member for holding the guide shafts at the opposite ends thereof and surrounding the zooming optical system; a fucusing optical system; a holder frame for permitting the focusing optical system to be moved along the optical axis independently of the zooming optical system; and a mechanism using a cam to drive the holder frame. Within the frame member surrounding the zooming optical system, a beam splitter for splitting an object light beam to derive a viewfinder light beam is interposed between the portion of the frame member remote from an object to be photographed and the zooming system. The side wall of the frame member is formed with an opening for passing therethrough the viewfinder light beam. Thus, the lengths over which the zooming optical system holder frames and the guide shafts are fitted together can be increased to enhance the zooming accuracy.

摘要： A zoom optical system is composed of a positive focusing lens group, a negative variating lens group, a negative compensating lens group and a positive rear fixed lens group. A rotating grooved cam moves the variating lens group and the compensating lens group in a given relation to each other along the optical axis in the normal focusing range. The focusing lens group is moved along the optical axis normal range for focusing. The variating lens group is kept stationary on the optical axis while the compensating lens group is moved along the optical axis during close-range focusing.
