DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a timer device for a magnetic recording/reproducing apparatus that can set the recording order on a magnetic tape when making timer reservations for a plurality of programs.

(b) Conventional technology In general, in a timer reservation device of a magnetic recording/reproducing device, when timer reservations are made for multiple programs, the multiple programs are recorded on the magnetic tape as a recording medium in order of start time. Publication No. 60-83242 discloses that in timer recording, in order to start recording without disturbing the joint between recorded parts during playback and without generating any unrecorded parts, tape winding is started a predetermined time before the set time to start timer recording. A technique has been disclosed that starts reversing, detects a previously recorded portion, and performs continuous recording from that point onwards.

(c) Problems to be Solved by the Invention In the above-mentioned conventional timer reservation device of the magnetic recording/reproducing device, when timer reservations are made for a plurality of programs, the plurality of programs are not stored on the magnetic tape which is the recording medium. Since the recording start time is recorded in the order of earliest recording start time, for example, if the recording start time of a program that is expected to be played back frequently is recorded later, the recorded background will also be recorded later on the magnetic tape. Therefore, when the magnetic tape wound on the reel in the cassette is at the beginning of winding, it is necessary to perform fast forwarding, and when rewinding for repeated playback, the start of the program is necessary. There is a problem in that cumbersome operations such as having to end rewinding at a certain position are required.

When the magnetic tape is not located at the recording position stored in the memory, a system CPU drives a tape drive means to perform fast forwarding or rewinding to position the magnetic tape at the recording position. The above problem is solved by a reservation device.

(e) Effect: According to the timer reservation device of the magnetic recording/reproducing device of the present invention, in addition to the recording times of a plurality of programs, it is also possible to input the recording order of the plurality of programs on the magnetic tape into the timer operation section. , the timer CPU sets the recording positions of the plurality of programs on the magnetic tape according to the reservation information input to the tie rod operation section, and schedules recording of the plurality of programs in order of recording start time before a predetermined time. When the position of the magnetic tape is detected by the magnetic tape position detection means, and the magnetic tape is not located at the recording position stored in the memory of the timer CPU, the system CPU drives the tape drive means to perform fast forwarding or winding. The magnetic tape is returned to the recording position and reserved recording is performed.

At the same time as fast-forwarding or rewinding the magnetic tape (2), the control head (6) transmits a detection control pulse via the system CPU (9), and by counting the control pulse, the recording position is moved to the recording position. A stop command is transmitted to the tape drive means (7) so that the magnetic tape (2) is positioned at the same position, and the drive of the reel motor (8) is stopped (step @).

As described above, after the magnetic tape (2) is sent to the recording position through step (2), if the magnetic tape (2) arrives at the recording position from the beginning (step @
YES), when the recording start time of the program to be recorded comes, the main power is turned on and the program is recorded at the recording position set in step (2) above (step 0). Next, the timer CPU (3) determines whether or not the reservation recording of all the programs input in the above-mentioned step (2) has been completed (step (2)). If not (step ■NO), step ■ to step ■ are repeated until it is determined that reservation recording of all programs has been completed in step ■ described above (step ■YES), and reservation recording of all programs is completed. If it is determined that the timer reservation device has done so, the main power source is turned off (step ① YES), and the operation of the timer reservation device is completed.

The above is the operation of the timer reservation device of the magnetic recording/reproducing device which is an embodiment of the present invention.In order to explain the operation of the timer reservation device more specifically, the timer recording reservation shown in the table of FIG. An example of inputting information into the timer reservation device will be described below.

First, turn on the main power of the magnetic recording/reproducing device, and run the programs NOI, NO2, and N shown in the table of FIG.

After inputting the recording start time and recording end time in step 3 into the timer operation section (1), the operator selects the desired magnetic tape (

Then, the timer CPU (3) sets the recording position of the programs NOI, NO2 and NO3 on the magnetic tape (2) based on the position A and the timer recording time input in step (3) above. And the recording order on the magnetic tape (2) input in step (2) above is calculated and set (step (2)). Next, when the operator turns on the timer switch, the main power is turned off and only the timer unit operates, and it starts comparing the current time with the recording start time of the next scheduled recording program, and enters the scheduled recording standby state. (Step O).

Next, among the aforementioned programs NOI, NO2, and NO3, the recording start time of the program NOI with the earliest recording start time is AMIO:00, and if it is before the predetermined time of AMIO200 (at least 10 minutes or more), The timer CPU (3) determines whether or not the magnetic tape (2) is located at the recording position set in the aforementioned step [phase]. ) is located at the position A, and the position C shown in FIG. 4 is the recording position set in step O above.
(Step @No), the timer CPU (3) drives the magnetic tape (2) to the tape drive means (7) via the system CPU (9).

2) is located at the position B (step ■YE
S) When the recording start time of the program No. 3 reaches 9:00 PM, the main power is turned on and scheduled recording starts, and if the scheduled recording continues until the recording end time of PMIO: 00, the program No. 3 will be completed. recorded between the position B and the position C, and the program NO.
The reservation recording of step 3 has been completed, and since the reservation recording of all programs input in step (2) has been completed (step (2) YES), the timer reservation recording operation of the timer reservation device is completed. The above is the operation of a timer reservation device for a magnetic recording/reproducing apparatus according to an embodiment of the present invention when the timer recording reservation information shown in FIG. 3 is input.

In addition, in steps (2) and (2), the presence or absence of any two programs whose recording end time and recording start time are within 10 minutes among the plurality of input programs is detected (step (2) ) and step ■YE
In the case of S, it is determined whether the recording order of the two programs on the magnetic tape (2) is continuous in the order of recording start time (step ■).The reason is that if step ■N
In the case of O, if you proceed with the scheduled recording operation, fast forward or rewind will be performed after the recording of the program with the earlier recording time among the two programs described above is completed (step ■), and the recording set in step [phase] will be performed. This is because, while the magnetic tape (2) is being sent to the position, the recording start time of the later recording time of the two programs may be reached.

(G) Effects of the Invention According to the timer reservation device of the magnetic recording and reproducing device of the present invention, in contrast to the conventional timer reservation device, the program is recorded on the magnetic tape in the order of recording start time. It becomes possible to schedule recording according to the recording order on the magnetic tape desired by the user. For example, when recording two programs, program A and program B, by reservation,
The earliest recording start time is the program A and the program B, but if it is okay to erase the program A, the program B and the program A should be recorded on the magnetic tape in that order. For example, it is advantageous in that it is useful when later erasing the program A and performing reserved recording.
