PURPOSE:To simplify the constitution of a recorder and reproducer device with picture display, by displaying a picture on a heat sensing recording medium reversible in the photo absorption characteristic with a multistylus thermal head according to the digital video information reproduced at the same time with voice, and erasing it with a thermal roller. CONSTITUTION:At the same time when voice is reproduced from the recording medium 1, the digital dot video signal is reproduced with the multihead 11 and applied to the multistylus thermal head 15 via the video signal read-in circuit 12, differentiation circuit 13, and inverting shaping circuit 14 to form the dot picture on the thermal recording medium 16 the photo absorption characteristic of which is reversible. This picture is erased with the thermal roller 20 to which the constant temperature higher than the temperature of the head 15 at the time of image formation. Thus, the constitution of the recorder and reproducer with picture display is simplified, because TV signal processing and the like are unnecessary. |
