    摘要: During the playback operation for freezing and storing a specific frame of a picture in a memory and thereafter printing the frame, the recording medium is turned reversely for a prescribed amount according to an instruction from a printer in response to the entry of the freeze command in order to accurately search the frame at the entry of the freeze, and thereafter the recording medium is played back in normal mode. The amounts of reverse turn and the successive forward turn in normal playback are counted and compared, and when the difference has become a prescribed value, a freeze signal is produced and the frame of the picture selected by the freeze command is stored in the memory and printed when required. This control method for use in a video print system is designed so that the recording medium is turned reversely for a prescribed amount according to an instruction from the printer and then stopped until the next command is entered.

    摘要: Disclosed is a video image printer for printing a video image of an input video signal onto a printing paper, in which a medium, such as a magnetic sheet disc or magnetic tape for a video cassette recorder, capable of recording/reproducing the information of the video image is employed. In order to obtain a reproduced video signal from the recording/reproducing medium with normal-operation, the video image printer is provided with a mechanical vibration-absorbing mechanism and an electrical reproduced signal correction circuit. Depending upon the requirements of the situation, a plurality of recording/reproducing heads are provided so as to make it possible to record a video image to be printed on the recording/reproducing medium during the printing operation of a previously selected video image.
