に記載のビデオテープレコーダ。[Claims for Utility Model Registration] ■ A reproduction control signal detection section that detects the presence or absence of a reproduction control signal, and a reproduction control signal detection section that is activated by the output signal of the detection section when there is no reproduction control signal and outputs a character signal for character display. Switching is controlled by the character signal generating section and the output signals of the detecting section when the playback control signal is present and when the playback control signal is not present, and when the playback control signal is present, the raw video signal of the tape is transmitted to the display device, and the A video cheap recorder comprising a switching section that transmits the character signal to the display device when there is no reproduction control signal. ■ The character signal generation part includes a counter part that divides the frequency of the reference clock signal and outputs an address signal, a memory part from which character data stored in the address signal is read out, and a frequency-divided signal of the reference clock signal and the counter part. a synchronous data creation unit that receives the address signal and forms a character signal together with the character data; a memory control unit that receives the address signal and outputs an active signal for commanding the character data readout to the memory unit; 2. The video tape recorder according to claim 1, further comprising a changeover switch that changes the output timing of the active signal and changes the display position of the character signal displayed on the display device by a switching operation.
