It was inconvenient to rewind and prepare for the next recording after each recording. The present invention has been proposed to solve such a problem, and provides a timer reservation setting circuit that enables a tape having a small unrecorded remaining amount to be effectively used.

An embodiment in which this timer reservation setting circuit is applied to a VTR will be shown.

る。In this figure, the remaining tape amount detection circuit 1 detects the unrecorded remaining amount of the recording tape 2. The remaining amount of unrecorded tape is detected by detecting the difference in rotational speed between the tape take-up reel and the delivery reel. The output of the tape remaining amount detection circuit 1 is supplied to a step size setting circuit 3 described later.

終了時刻データは、記憶回路9に記憶される。The recording end time setting switch 8 connected to the end time counter 7 via the step size setting circuit 3 sets the recording end time in the one-touch timer function. When the setting switch 8 is pressed, the value of the end time counter 7 changes by the numerical value set by the step size setting circuit 3 each time the setting switch 8 is pressed. The step width (time width) of the end time counter 7 that is advanced or lowered each time the setting switch 8 is pushed once is large when the unrecorded remaining amount is large, based on the information from the tape remaining amount detection circuit 1, and is not set. If the remaining recording capacity is low, it will be set to a smaller value. The numerical value counted by the end time counter 7 is sent to the timer reservation control circuit 6. The recording start time data and the recording end time data sent to the timer reservation control circuit 6 are stored in the storage circuit 9.

が終了される。The timer reservation control circuit 6 sends a recording start control signal to the video recording control circuit 10 at the recording start time based on the data stored in the storage circuit 9, and the recording tape is controlled under the control of the control circuit 10. Recording starts at 2. When the recording end time comes, a recording end control signal is sent to the video control circuit 10 to end the recording operation on the recording tape 2.

ちいち巻き戻すような不便さが解消される。As described above, according to the present invention, the unrecorded remaining amount of the tape is detected, and when the unrecorded remaining amount of the tape is large, the increment time width of one count of the end time counter is increased. When the setting is made and the unrecorded remaining amount is small, the step time width is set to be small, so that the tape with a small unrecorded remaining amount can be used more effectively. Therefore, it is possible to eliminate the inconvenience of rewinding an excessively unrecorded tape, which has been conventionally done, after recording is completed.
