The present invention relates to a circuit for warning the untimed setting of a video tape recorder. Specifically, the present invention relates to a circuit that displays the fact that the time is not set on the monitor when the time is not set at the time of one-touch recording and program set or on time / off time in the video tape recorder.

When using a video tape recorder, one-touch recording is often used, or a program is set to schedule recording. In some cases, the video tape recorder can be turned on and off automatically by setting on time / off time. In this case, you must use the time adjustment key on the video tape recorder to set the time, or time, to the video tape recorder. However, the conventional video tape recorder does not indicate that the time is not set when the time is not set. Therefore, the user often does not set the time, so one-touch recording and program set or on time / off time cannot be used. There were a lot. In addition, there was no indication that there is no display even when the user presses the visual adjustment key, which is often mistaken for set failure.

An object of the present invention is to provide a circuit for displaying an indication to adjust the time when the user presses a key related to the time adjustment so that the consumer can set the time to solve the above problems on the monitor screen.

The circuit of the present invention is a one-touch recording and program set of a video tape recorder, a time adjusting key (2) for adjusting the time of on time / off time, a video tape recorder operation key (4) for operating various functions of the video tape recorder, A timer microcomputer 6 that receives a signal from the time adjustment key 2 and the video tape recorder operation key 4, an on-screen display integrated circuit 8 that receives a signal from the timer microcomputer 6 and displays characters on the monitor 10. And a monitor 10 for displaying characters on the screen according to a signal transmitted from the on-screen display integrated circuit 8.

Hereinafter, the present invention will be described in detail with reference to FIGS. 1 and 2.

The circuit for executing the time-non-set warning method in the videotape recorder of the present invention includes a conventional videotape including a time adjustment key, a video tape recorder operation key, and a timer microcomputer that receives signals from the time adjustment key and the video tape recorder operation key. In the recorder, when a time adjustment key or a video tape recorder operation key connected to the timer microphone is operated, the recorder receives a signal from the timer microphone and displays a character on the monitor to display the character on the screen of the monitor. It is characterized by the fact that it is connected to display the setting warning.

The operation of the inventive circuit will be described in detail with reference to the flowchart of FIG. In the on-screen display execution mode, it is determined whether the power-on is applied. If it is on, it is determined whether the time is set, and if so, an on-screen display is performed. Otherwise, "PLEASE SET THE CLOCK" is displayed on the monitor 10, and it is determined whether there is any key input. If there is any keystroke, turn off the “PLEASE SET THE CLOCK” display and perform the on-screen display. If there is no key input, it is determined whether 5 seconds have elapsed. If not 5 seconds have elapsed, "PLEASE SET THE CLOCK" is displayed. When 5 seconds have elapsed, the display of characters on the monitor is stopped, and the timer microcomputer 6 determines whether there is a key input related to time. If there is no key input related to time, it performs on-screen display. If there is a key input related to time, " PLEASE SET THE CLOCK " is displayed on the monitor 10 to determine whether there is any key input. If there is any key input, turn off the display of “PLEASE SET THE CLOCK” and perform the on-screen display. If there is no key input, it is determined whether 5 seconds have elapsed. If not 5 seconds have elapsed, continue displaying “PLEASE SET THE CLOCK”. After 5 seconds have elapsed, the display stops displaying characters and performs an on-screen display.

Although the present invention has been described in detail only with respect to the embodiments described, it will be apparent to those skilled in the art that various modifications or changes can be made within the spirit and scope of the present invention, and such variations and modifications are within the scope of the appended utility model claims. Do.

Claims (1)

In a conventional video tape recorder comprising a time adjustment key, a video tape recorder operation key, and a timer microphone receiving a signal from the time adjustment key and the video tape recorder operation key, the time adjustment key or the video tape recorder operation connected to the timer microphone. In the case of key operation, the video tape recorder is connected to display a non-time setting warning on the screen of the monitor via an on-screen display integrated circuit which receives a signal from the timer microphone and displays characters on the monitor. Not set warning circuit.
