That is, in the device having the above-described configuration, when the end point result signal is input from the end sensor unit 18 during the reservation recording, the microprocessor 8 is based on the stored data of the state memory 20. Control to perform the rewind reservation recording operation.

Next, the present invention will be described in more detail with reference to the flowchart of FIG. 2.

First, when a user inputs a series of reservation recording data such as a reservation recording start time and a reservation recording end time to perform a reservation recording, the microprocessor 8 outputs the corresponding reservation recording data to the reservation recording processing unit 19. . Then, the reservation recording processing unit 19 stores the reservation recording data input from the microprocessor 8 in a predetermined memory, and continuously searches for the reservation recording start time. Thus, when the scheduled recording start time comes, the resultant signal is output to the microprocessor 8, and then the microprocessor 8 is driven to control the deck driver 13 and the deck 14 to perform the reserved recording. Done.

On the other hand, when the user inputs the rewind reservation recording function key 6a, the microprocessor 8 controls to store the mode as predetermined flag data in the state memory.

Then, as described above, when the reservation recording start time is performed and reservation recording is performed (steps ST1 and ST2), the microprocessor 8 continuously checks whether the reservation recording end time has been reached and whether the currently running tape has ended. (Steps ST3 and ST4).

At this time, when a predetermined result signal for the reservation recording end time is input from the reservation recording processing unit 19, the microprocessor 8 terminates the deck 14 and the deck driver 13 to terminate the reservation recording operation. (ST5 step)

In addition, the microprocessor 8 retrieves the recording data of the state memory 20 when a predetermined result signal for the tape end point is input from the end sensor unit 18 (step ST6). At this time, if the recorded data is not the rewind reservation recording data, the control proceeds to step ST5 to terminate the reservation recording end operation, and when the rewind reservation recording data is obtained, the deck 14 and the deck driver 13 are driven and controlled. The tape rewind operation is controlled (step ST7).

At this time, if a predetermined result signal for the start of the tape is input from the start sensor unit 17 during the rewinding operation, the rewinding operation is terminated, and the deck 14 and the deck driving unit continue to perform reservation recording. (13) and the like (ST8 step).

In this case, the microprocessor 8 reads predetermined OSD control data from the OSD data memory 21 and drives the OSD generator 22 based on the data to perform a rewind reservation recording operation. And outputting an OSD message indicating that a rewind schedule recording operation is performed to the recording processor 16. Then, the recording processing unit 16 mixes the OSD message input from the OSD generating unit 22 with the broadcast signal and records it on the tape. (ST9 step)

That is, according to the above, even if the tape is terminated during the reservation recording, the recording is automatically performed after the rewind, so that the maximum recording service can be provided to the user except for the unrecorded portion for several minutes.

On the other hand, the present invention is not limited to the above embodiments and can be modified in various ways without departing from the technical gist of the present invention.

As described above, according to the present invention, when the tape is over during the scheduled recording, the automatic rewinding is performed, and then the scheduled recording function is continuously performed to provide the maximum recording service to the user. Televideo with functions can be realized.
