Abstract: PURPOSE:To accurately measure light by connecting the optical path of a photometric optical system so that the photometric area of a photometric sensor coincides with a photographic area at the time of close-up photographing such as film photographing. CONSTITUTION:In a camera holder 22, a close-up optical system 30 consisting of a close-up lens 32 and a photometric correction optical system 33 which corrects the optical path to lead the light in the photographic area to a photometric sensor window 3 and consists of a prism 34, etc., are supported in the position facing a photographic lends optical system 2 of a camera 1 and the position facing the photometric sensor window 3 respectively through a supporting member 36. The optical path of the film image is corrected by the optical path correcting prism 34 and the film image is led to the photometric sensor window 3 by an optical path L2 and is condensed through a photometric lends 12 and is made incident on a photometric sensor 13. Thus, light measuring in the photographic area is possible, and accurate light measuring is performed even when the photometric area and the photographic area are different.

Abstract: PURPOSE:To eliminate a need to provide an optical system which leads an object image to a finder and to prevent the camera blur by forming an aperture part through which a film in a film photographic adapter can be directly seen at the time of film photographing. CONSTITUTION:A camera holder 22 is provided with a fixing screw 28 which accurately fixes a camera 1 to its set position at the time of setting the camera 1, and an aperture part 23 for film confirmation is so formed that a film F on a film placing face 20a can be directly visually confirmed from the external. The film face in a photographic area can be confirmed from above through the aperture part 23 by an optical path L3. Thus, it is unnecessary to newly provide the optical system which leads the object image to the finder, and the camera blur is prevented.

Abstract: PURPOSE:To satisfactorily photograph whether a film is set longitudinally or transversely by enabling the film to be inserted onto a film placing part in two directions orthogonal to each other and positioning the film by a means which presses plural positions on the outside of the photographic area and on diagonals of the photographic aria. CONSTITUTION:A film photographic adapter device 20 is provided with a camera holder 22 which holds a camera 1 on a film placing face 20a extended to film insertion slits 21a and 21b, and a film F can be inserted in two directions of arrows (a) and (b) orthogonal to each other. A film retaining member 37 is provided which positions the film F or a film holder FH in each frame and elastically presses it to suppress its rise for the purpose of keeping the object distance constant, and its pression position is set in two positions on the outside of the photographic range of the film F and on diagonals of the photographic area. Thus, photographing is satisfactorily performed whether the film F is longitudinal or transverse.

Abstract: PURPOSE:To use the receiving means for recording a voice in common to a multipurpose by discriminating and fetching a remote control signal or a distance measuring signal from a receiving signal of a voice. CONSTITUTION:When a shutter switch 61 or a sound recording switch 62 of a remote control is depressed, a transmitting circuit 60 transmits an acoustic wave corresponding to each of them from an oscillating means 63. The acoustic wave transmitted from the remote controller is received by a microphone 11, a received signal is supplied to a receiving circuit 21 and the receiving circuit 21 discriminates whether the received signal is for photographing or sound recording and supplies a signal corresponding thereto to a system controller 50. The system controller 50 executes one operation of video recording or voice recording by this signal. In such a way, a receiving means for recording a voice can be used in common to a multi-purpose.

Abstract: PURPOSE:To prevent dusts to stick on the light incident surface of a solid-state image pickup element by installing the solid-state image pickup element on a base plate supporting a shutter mechanism. CONSTITUTION:A solid-state image pickup element 1 is installed on a base plate 3 supporting the shutter mechanism. A cover 4 to cover the incident surface of this element 1 is joined with the base plate 3. A filter 2 to adjust the sensitivity of the element 1 is arranged in a position confronting with the light incident surface of the element 1 and this filter 2 is fixed on the cover 4. The shutter mechanism is constituted by a leading curtain 5 and a trailing curtain 6 which are rotatively fitted into a shaft 7 fixed on the base plate 3. A dust contamination into the shutter mechanism and a dust adherence to the light incident surface of the solid state image pickup element can be prevented.

Abstract: PURPOSE:To make an apparatus small-sized and prevent the infiltration of water into the apparatus by making a driven member and an operating member movable linearly in the same direction and forming a drain groove on the wall face of a housing room of the operating member. CONSTITUTION:When a finger is pressed on the projection 3a of an operating member 3 and the rightward force is applied to the finger, the rightward force is also applied to a sphere 5, the sphere 5 escapes from a recess 2a, and the member 3 starts to be moved to the right. A driven member 3c is moved to the right, when the member 3 reaches the preset position, the sphere 5 drops in a recess 2b, and the member 3 is stopped. When the strong rightward force is applied to the finger pressing the projection 3a, the sphere 5 escapes from the recess 2b, the member 3 is again moved to the right, when the sphere 5 drops in a recess 2c, the member 3 is stopped. Contact pieces 7a and 7c of a switch 7 are brought into contact by the tip of the driven member 3c. During the moving process of the member 3, the water accumulated in the excess space S1 of the housing room of the member 3 is pushed out into a drain groove 1a then discharged to the outside of the room through an opening 1b.

Abstract: PURPOSE:To easily and certainly detect the replacement and replenishment period of a recording material such as ink or an ink ribbon, by issuing an alarm or prohibiting operation when the number of times of the reciprocating movement of a paper feed roller, which reciprocating moves between a retracted position and an operation position each time a cut sheet is automatically fed, become larger than a predetermined value. CONSTITUTION:When a recording apparatus is started and the operation order from a host machine is present, a paper feed roller 11 reciprocating moves between a retracted position and an operation position and, when the number of times of reciprocating movement exceed the predetermined number of times and the switch of a counter is turned ON, alarm display is issued to discriminate whether the reciprocating movement of the paper feed roller 11 is based on the continuous recording from an external apparatus. When said movement is based on the continuous recording from the external apparatus, recording operation is prohibited. When the switch of the counter is not yet turned ON, regular recording operation is performed to complete a series of operations.

Abstract: PURPOSE:To judge securely whether a film can be rewound or not regardless of the total number of frames of the film by providing a reference voltage selecting means which varies the level of a reference level to be compared with a source voltage according to the total number of frames of the film. CONSTITUTION:The reference voltage corresponding to information N on the total number of film frames inputted to the reference voltage selecting circuit 2 is outputted selectively to a source voltage comparing circuit 7. When the (n- 1)th frame is exposed, the (n)th frame of the film begins to be wound and a in- winding signal F from a perforation detecting circuit 11 is passed through a timing generating circuit 8 to output a high-level signal to a latch circut 9. At this time, a signal showing whether the level of the source voltage is higher or lower than the reference voltage is inputted to the source voltage comparing circuit 7, and this signal is sent to a decision circuit 12; when the source voltage is higher than the reference voltage, it is judged that the film can be rewound, and when an exposure end signal D is inputted, a film winding signal I is outputted to a driving circuit 13.
