摘要： Moving elements in a recording and/or reproduction apparatus change the travel path of a strip-like recording medium mounted in a container. A detector detects a specified part of parts of the medium having a character different from other parts of the medium and at least part of a light emitting and/or light receiving arrangement of the detector moves into and out of the space required for altering the path of the medium.

摘要： A color video camera includes an image pick-up device for converting images into electrical signals including a plurality of color signal elements, white picture forming circuitry for introducing a white picture to the image pick-up device and a white balance control for controlling a proportion of each color signal element contained in an output of the image pick-up device so as to have a prescribed ratio. A power source switch is included for supplying current to individual circuits in the video camera. The camera also includes an operation member having three positions. The member turns off the power source switch in a first position; it turns on the switch in a second position to control the white picture forming circuitry and introduces the white picture to the image pick-up device, thereby actuating the white balance control; in a third position it turns on the power source switch to control the white picture forming circuitry so as to prevent introduction of the white picture to the image pick-up device. The second position is located between the first and third positions.

摘要： A motion picture projector having various functions such as, projecting and rewinding, all of which can be selectively performed by a single control knob, and including an intermittent-drive film advancing mechanism which comprises a pull-down structure, a compound cam of an up-and-down cam wheel and an in-and-out cam disk, and first and second cam followers arranged between the pull-down structure and the compound cam to be consecutively operated so that the pull-down claw enters the perforations of the film and moves it in a forward direction always by the length of a frame and at a desired frequency through a film gate mechanism. The film gate mechanism consists of a film guideway, a resilient thin aperture plate self-biased to move away from the film guideway and defining an actual projection aperture, and a movable film gate member arranged on the opposite side of the aperture plate from the guideway and biased to urge the aperture plate for guidance and support of the film against the guideway. The pull-down structure and the film gate member have respective input means arranged to be consecutively actuable by a common mode changeover means cooperative with the control knob. The mode changeover means has at least three switched positions, that is, a first position for a normal projecting operation, a second position where the pull-down structure is maintained disengaged from the in-and-out cam follower to project a still picture, and a third position where the film gate member and the aperture plate are spaced from the film guideway to permit continuous transportation of the film at a far faster speed than that occurring in the normal projecting mode of operation.

摘要： A recording and/or reproducing device arranged to use a cassette containing a recording medium such as a tape, includes a tape loading mechanism operative to displace the tape contained in the cassette to a position at which the tape is in operative relation to a recording head. A cassette displacing arrangement into which the cassette is first loaded is movable to a position where the cassette is in operative relation to the tape loading mechanism. A member on the displacing arrangement serves to hold the cassette at a certain position relative to the displacing arrangement so that the cassette will be moved into operative relation with the tape loading mechanism by the displacing arrangement.

摘要： The present invention relates to a synchronization system of a cine-projector with a sound tape reproducer. It is characterized in that the phase of a signal corresponding to the film feeding speed of the film projector and that of a signal corresponding to the standard speed coming from the sound tape reproducer are compared with each other so as to control the film feeding speed of the cine-projector by means of the comparison output corresponding to the phase difference. In order to accomplish this, between the driving source for driving the internal mechanism of the cine-projector and the driving member for the internal mechanism, a transmission speed varying mechanism is provided in such a manner that the transmission speed varying mechanism is controlled by means of the film speed control driving source to be driven by the comparison output so as to maintain the synchronized state.

摘要： A tape cassette and a video recording and reproducing system using the same are disclosed. This system provides an increase in the recording capacity of video signals despite the reduction of volume of a tape within the cassette and the resultant reduction in the bulk and size of the cassette and can be loaded with the tape cassette on selection of two conditions. The tape cassette will be turned upside down after the video signals have been recorded on either one of the upper and lower halves of the width of the tape.

摘要： Disclosed is a sound motion picture projection apparatus in which a head pad is urged by a spring member toward a film pressing position at which position the head pad presses a film against a magnetic head disposed along the sound recording and reproducing film path. The apparatus has a set mechanism of the self-holding type which sets the head pad against the urging force of the spring member to a film pressure releasing position at which position the head pad releases the pressing of the film, by the driving force of a driving motor and keeps the head pad to that position. The apparatus further has a film detecting member which is disposed in said sound film path after the magnetic head and operatively connected with the set mechanism in such a manner that the holding of the head pad at the film pressure releasing position by means of the set mechanism is released when the film detecting member detects the film introduced into the sound film path and thereafter the setting operation of the set mechanism is made ineffective as long as the film detecting member detects that a film exists in the sound film path. Thereby when the set mechanism is driven by the driving motor when no film exists at least in the sound film path, the head pad is automatically set to the film pressure releasing position and then the head pad is automatically changed from the film pressure releasing position to the film pressing position when the film detecting member detects the introduction of the film into the sound film path.

摘要： An automatic facsimile signal analyzing system includes a switch unit, a service trunk, a signal identification trunk, a facsimile communication determination unit, and a control unit. The signal identification trunk restores a facsimile control signal from a modulated and encoded facsimile signal on the set speech path and performs collection of communication state information and detection of a start of facsimile communication on the basis of the restored facsimile control signal. The facsimile communication determination unit permits an operation of the signal identification trunk when the classification result from the service trunk represents a type other than the voice signal and analyzes the communication state information from the signal identification trunk. The control unit performs switching/connection control of the switch unit, connects the service trunk and the signal identification trunk, both of which are in an idle state, to the set speech path upon setting of the speech path, disconnects the service trunk from the speech path when the classification result is output, and disconnects the signal identification trunk from the set speech path when the classification result from the service trunk represents the voice signal and when a call corresponding to the set speech path is ended.
