    摘要: A camera using a film having a magnetic surface for recording magnetic data thereon. The camera includes a magnetic head for writing magnetic data onto the magnetic surface and for reading magnetic data recorded thereon. A pad movable with respect to the magnetic head is opposed to the magnetic head. The film is sandwiched between the pad and the magnetic head when magnetic data is written onto the magnetic surface of the film and the magnetic data recorded thereon is read. The pad is driven by a motor for driving a film feeding mechanism so that the pad moves away from the film feeding path when data writing and data reading is not carried out. A planetary gear mechanism connects the motor selectively to a pad driving mechanism and a film feeding mechanism.

    摘要: An image reproducing system which can automatically output only a portion of an image recorded on a film which conforms to trimming information set upon photographing as an electric image signal without the necessity of a manual operation. The image reproducing device comprises means for detecting an image recorded on a film, means for reading trimming information of the image, the trimming information being recorded on a record medium when the image has been recorded on the film and representing a condition of reproduction of the image, means for generating an electrical image signal in accordance with the image detected by the detecting means, and means for controlling an output of the electrical image signal to be generated by the generating means in accordance with the trimming information read by the reading means.

    摘要: A camera exposure data setting device for setting exposure data in digital form in response to on or off of switches. A first switch actuating member is manually operable for changing mainly an exposure time value and is located at or about the position where a shutter speed setting dial is located conventional cameras, and a second switch actuating member is manually operable for changing mainly a diaphragm aperture value and is located at a position of the camera opposite from the position of the first switch member with respect to the vertical plane passing the optical axis of an objective lens. The first switch actuating member is operated for changing the exposure time value in an exposure time priority automatic exposure control mode and a manual exposure control mode and changing the diaphragm aperture value in a diaphragm aperture priority automatic exposure control mode, and the second switch actuating member is operated for changing the exposure time value in the exposure time priority automatic exposure control mode and the diaphragm aperture value in the exposure time priority automatic exposure control mode and the manual exposure control mode.

    摘要: A composite magnetic head comprising a read/write head section (6A) wherein a plurality of thin film heads are joined such that respective head gaps (R/W-1, R/W-2, . . . ) are aligned at predetermined intervals in the widthwise direction of tracks (T1, T2, . . . ), and an erase head section (6) wherein a plurality of bulk heads respectively corresponding to the thin film heads are joined such that respective head gaps (E1, E2, . . . ) are aligned at predetermined intervals in the widthwise direction of the tracks (T1, T2, . . . ), wherein the read/write head section (6A) and the erase head section (6B) are joined in the longitudinal direction of the tracks (T1 T.sub.2, . . . ) such that the head gaps (R/W-1) and (E1) and (R/W-2) and (E2) of the respective sections are relatively close to each other.The thin film heads can be replaced with a plurality of bulk heads (60A). A means (SW1-SW4, 77) can be added for two magnetic heads so that a predetermined voltage-divided signal of a read signal of one magnetic head differentially acts on a read signal of the other magnetic head. A step-up transformer (31, 32) can be mounted on a base (7) so as to step up the level of the signal picked up by a head chip (6) mounted on the base (7). A read/write switch circuit (100), a write amplifier (93), and a differential input amplifier (90) can be formed into a hybrid IC and mounted on the base (7).
