It is preferable to switch the recording to the deck 14 promptly. In the first embodiment, the second deck 14 is started up after the operation input to the reproduction start switch 22, but the second deck 14 can be set in a pause state before that.

The end of the first recording / reproducing switching operation on the second deck 14 and the first reproducing operation on the first deck 12 will be described first with reference to the operation shown in FIG. In the case of FIG. 2, before the operation of reproducing the information on the first video tape set in the first deck 12 ends,
A recording end command is output from the time counter 28.
In this case, the second recording-reproduction switching control unit 52 inputs a recording end command from the clock counter 28 at 11:00 pm, so that the determination in step 3 in FIG. 6 becomes YES and a recording end signal is output ( Step 4 in FIG. The second recording / playback switching control section 52 further includes a second deck 14
Is stopped, and the tape count value XE2 at this time is acquired by the second tape counter 18 (step 6 in FIG. 6). The second recording / playback switching control unit 52 further includes
Tape start count value XS obtained in step 1 of
The second video tape is rewound to 2 (step 7 in FIG. 6).

Thereafter, the second recording / reproducing switching control section 52 repeats the determination in step 8 until the determination in step 8 in FIG. 6 becomes YES.

On the other hand, the first deck 1 whose reproduction operation is continuing
2 is controlled by the first reproduction / recording switching control unit 44. The first reproduction / recording switching controller 44 determines whether or not the first video tape has reached the tape count value (XE1-A) based on the output from the first tape counter 16 (FIG. 5). Step 4). Although the count value A will be described later, here, it is determined whether or not a predetermined tape count value before reaching the recording end position on the first video tape has been reached. When the determination in step 4 in FIG. 5 is YES, the first reproduction / recording switching control unit 44 determines whether a recording end signal has already been output (step 5 in FIG. 5). In the case of the operation example shown in FIG. 2, since the recording end signal has already been output in step 4 in FIG. 6, the determination in step 5 in FIG. 5 is YES.

Thereafter, the first reproduction / recording switching control section 44
Determines whether the first video tape has reached the tape count XE1, which is the recording end position, based on the output from the first tape counter 16 (step 7 in FIG. 5). When the determination in step 7 in FIG. 5 is YES, the first

Further, the first reproduction / recording switching control unit 44 determines that the recording end signal has already been output by executing step 10 in FIG. 5, thereby ending all the operations for the first deck 12.

When the reproduction switching signal is output in step 9 in FIG. 5, the determination in step 8 in FIG.
The second recording / playback switching control unit 52
Is started (step 9 in FIG. 6).

In the case of the operation example shown in FIG.
In order to stop and drive No. 4, the second reproduction / recording switching control unit 54 executes Steps 10 to 15 in FIG. First, the second reproduction / recording switching control unit 54
Indicates that the tape count value of the second video tape is (XE2
-B) is determined (step 1 in FIG. 6).
0). Although the count value B will also be described later, here, it is assumed that the determination in step 10 is YES at the timing before reaching the tape count value XE2. In step 11 of FIG. 6, since the recording end signal has already been output, the determination here is YES, and the process proceeds to step 13 of FIG. When the tape count value of the second video tape has reached the recording end position XE2, the determination in step 13 of FIG.
4 is stopped (step 14 in FIG. 6). Thereafter, the second reproduction / recording switching control section 54 outputs a reproduction switching signal (step 14 in FIG. 6), but since the first deck 12 has already completed all operations, this signal is invalid. Becomes Further, in the case of the operation example of FIG. 2, since the recording end signal has already been output, the determination in step 16 of FIG. 6 becomes YES, and all the operations of the “simultaneous recording / playback operation” of the present invention are ended. I do.

The second and subsequent recording operations on the first deck 12 In the case of the operation example of FIG. 3, unlike the operation example of FIG.
During the first reproduction operation on the first deck 12, a recording end signal has not been input. In this case, the operation of the second deck 14 will be described first. Since the determination in step 3 in FIG. 6 is NO, the process proceeds to step 5 in FIG. In step 5 of FIG. 6, it is determined whether or not a reproduction switching preparation signal to be described later has been output. As long as the determination in step 5 of FIG. 6 is NO, the recording operation of the second deck 14 is continued. Will be.

On the other hand, the operation of the first deck 12 will be described. After the reproduction operation of the first deck 12 is started in step 3 of FIG. 5, during the first reproduction operation, a recording end signal is output. Since no data is output, the determination in step 5 of FIG. 5 is NO. As a result, the process proceeds to step 5 in FIG. 5, and a reproduction switching preparation signal is output. The timing at which this playback switching preparation signal is output is
This is when the determination in step 4 of FIG. 5 is YES.
At this time, the determination in step 5 in FIG. 6 is YES, the second deck 14 during the recording operation is stopped, and the count value XE2 of the recording end position is obtained (step 6 in FIG. 6). Thereafter, the second deck 14 is rewound to the tape head count value XS2 (step 7 in FIG. 6).

In realizing the operation shown in FIG. 3, the switching between the reproduction operation on the first deck 12 and the reproduction operation on the second deck 14 is smoothly performed to reduce the blank period occurring on the reproduction screen. Is preferred. For this purpose, the second playback operation is performed before the first playback operation on the first deck 12 is completed.
It is better to rewind the deck 14 to the tape head count value. In the first embodiment, the second deck 14
In step 4 of FIG.
We go when it becomes S. Therefore, step 4 in FIG.
The tape count value A in the above is a time enough for the second deck 14 to rewind the second video tape to the tape start count value before the reproduction operation on the first deck 12 ends. What is necessary is just to be set.

When the rewinding operation of the second deck 14 is completed by the execution of step 7 in FIG. 6, in synchronism with step 9 in FIG. The determination is YES, and the first reproduction operation on the second deck 14 is started in step 9 of FIG.

On the other hand, the first deck 12 proceeds to step 11 in FIG. 5 because the determination in step 10 in FIG. 5 is NO. That is, the first reproduction / recording switching control unit 44 rewinds the first video tape set on the first deck 12 to the tape head count value XS1 (step 11 in FIG. 5), and immediately thereafter. The recording operation of the first deck 12 is controlled to start (step 12 in FIG. 5).

In this way, the second recording operation on the first video tape set on the first deck 12 is started.

The third and subsequent reproduction / recording switching operations for the first video tape set on the first deck 12 are performed by the first reproduction / recording switching control unit 44 from step 4 in FIG. This is performed by performing Step 12.

Regarding the Second and Subsequent Playback Operations of the First Deck The second and subsequent recording / reproduction switching control for the first video tape set in the first deck 12 is performed in the third manner.
Is performed by the recording / reproduction switching control unit 46. This operation step is shown in steps 13 to 18 and step 3 in FIG. Steps 13 to 18 in FIG. 5 are the same as steps 3 to 8 in FIG.
The recording end signal is output only when the recording end time has come during the recording operation on the first deck 12 (step 14 in FIG. 5), and when it is determined in step 18 that the reproduction switching signal has been output, Only the operation proceeds to step 3, and the reproduction operation of the first deck 12 is started.

Here, in the first deck 12, the second deck
In the case where the recording operation is switched to the reproducing operation after the second recording operation, it is preferable that the reproducing operation on the first deck 12 is started immediately after the reproducing operation on the second deck 14 is completed. This is preferable because the number of blank sections can be reduced. The tape rewinding operation before switching from the recording operation to the reproducing operation in the first deck 12 is performed in step 17 in FIG. 5, and the timing of this rewinding is determined as YES in step 15 in FIG. Wait for it to be done.
The reproduction switching preparation signal defined in step 15 in FIG. 5 is output by executing step 12 in FIG. 6, and the timing at which the reproduction switching preparation signal is output is determined in step 10 in FIG. The tape count value of the second video tape being played on the deck 14 of (XE2-
B). The tape count value B defined in step 10 of FIG. 6 is also the same as the tape count value A defined in step 4 of FIG. Defines the timing before the reproduction operation on the second deck 14 ends. As described above, the tape count value A in step 4 in FIG.
When the playback operation is switched from the first deck 12 to the second deck 14 by setting the tape count value B in the above to a predetermined value, it is possible to switch from the second deck 14 to the first deck 12. Also in the case of switching, screen reproduction can be performed almost continuously without providing a blank section on the reproduction screen.

As described above, in the first deck 12,
When performing the second or subsequent recording operation, switching to the reproduction-recording operation is performed by the first reproduction-record switching control unit 44,
When performing the second or subsequent reproduction operation on the first deck 12, recording-reproduction switching can be performed by the third recording-reproduction switching control unit 46.

On the other hand, in the second and subsequent recording and reproducing operations of the second deck 14,
When performing the recording operation after the first time, reproduction-recording switching can be performed by the second reproduction-recording switching control unit 54,
When performing the second or later reproduction operation on the second deck 14, the switching control of the recording-reproduction operation can be performed by the second recording-reproduction switching control unit.

By such control, as shown in FIG. 3, the recording operation and the reproducing operation can be alternately repeated in the first deck 12 and the second deck 14.

In the case of FIG. 3, the operation of FIG.
During the playback operation on the deck 12, a recording end signal is input, so that a recording end signal is output in step 4 of FIG. 6, and then the tape end count value XS2 is reached in step 7 of FIG. After rewinding the video tape, the second deck 14 waits until a reproduction switching signal is output in step 8 of FIG. Meanwhile, the first deck 1
Since it is determined on the side 2 that the recording end signal has been output in step 5 in FIG. 5, after performing the reproducing operation up to the recording end position in step 7 in FIG. 5, step 8 in FIG.
, The reproduction operation on the first deck 12 is stopped. Further, a reproduction recording signal is output in step 9 in FIG.
Thereafter, since the determination in step 10 in FIG. 5 is YES, all the operations in the first deck 12 are completed.

When the reproduction switching signal is output in step 9 in FIG. 5, the determination in step 8 in FIG.
The last reproduction drive on the second deck 14 is started. When the tape recording end position is reached, the determination at step 13 in FIG. 6 is YES, the reproduction operation on the second deck 14 is stopped (step 14 in FIG. 6), and the process proceeds to step 16 in FIG. , All the operations on the second deck 14 end. Note that a playback switching signal is output in step 15 of FIG. 6, but since all operations on the first deck 12 have been completed, this playback switching signal is invalidated.

Although the embodiment of the present invention has been described above, the present invention is not limited to the case where the timer recording switch 20 is operated and then the reproduction start switch 22 is operated to perform the “simultaneous recording / reproduction operation”. For example, when bathing from 9:00 pm to 9:20 pm while watching a broadcast program broadcasted from 8:00 pm to 10:00 pm, the recording start switch 24 is operated at 9:00 pm If the recording operation is started on the first deck 12 and the reproduction start switch 22 is operated at 9:20 pm after bathing, the “simultaneous recording / reproduction operation” is performed in the same manner as the operation of the above-described embodiment.
It can be performed. In this case, unlike the case of timer recording, the recording end time is not input at the start of recording. However, when the recording end switch 26 is operated at 10:00 pm, the recording end from this switch 26 is completed. The command can be handled in the same manner as the recording end command from the clock counter 28 in the above-described embodiment.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIGS. FIG.
In the device of the second embodiment shown in FIG. 7, in addition to the configuration of the device of the first embodiment shown in FIG.
And a read driver 74. Auxiliary memory 70
Is a small memory such as a semiconductor storage device, which stores video information, audio information, and the like in a readable and writable manner. A write driver 72 and a read driver 74 that access the auxiliary memory 70 perform information writing driving and information reading driving with respect to the auxiliary memory 70 based on a command from the deck control unit 30. is there.

Next, "simultaneous recording / reproducing operation" in the second embodiment will be described with reference to FIG.
FIG. 8 shows the same operation example as FIG. 3, in which a recording start command is output at 9 pm and a reproduction start command is output at 9:20 pm. The first recording operation and the first reproducing operation on the second deck 12 shown in FIG. 8 and the first recording operation on the second deck 14 are performed in the same manner as in the first embodiment. That is, the first recording operation on the first deck 12 is performed in steps 1 to 4 of FIG.
Is performed. When the reproduction start command is output at 9:20 pm, the determination in step 7 in FIG. 4 becomes YES, and the first deck 12 executes steps 1 to 3 in FIG. Deck 1
The first reproduction operation in 2 is started. On the other hand, on the second deck 14 side, the first recording operation on the second deck 14 is started by executing steps 1 and 2 in FIG.

The difference between the second embodiment and the first embodiment is that the recording blank between the end of the recording operation on the second deck 14 and the start of the recording operation on the first deck 12. During this period, information input during that period is written and driven in the auxiliary memory 70. Thus, the information in the blank space in the first embodiment can also be recorded in the auxiliary memory 70. The write driver 72 shown in FIG. 7 drives the writing of information to the auxiliary memory 70 based on a command from the deck control unit 30.
Here, the deck control unit 30 controls the 1
Immediately before ending the second recording operation, step 6 in FIG.
Since a reproduction switching preparation signal is output, the information writing operation of the writing driver 70 may be started based on the reproduction switching preparation signal. The operation of ending the information writing operation by the writing driver 72 may be performed based on this detection signal by detecting the rewind operation before the start of recording in the first deck 12.

On the other hand, the reading of the information written in the auxiliary memory 70 may be started in synchronization with the end of the reproducing operation on the second deck 14.
Information reading can be started based on the reproduction switching signal from 0. In the operation example shown in FIG. 8, after the reproduction operation on the second deck 14 is completed, first, the information written in the auxiliary memory 70 is read, and thereafter, the information recorded on the first deck 12 is read. Is played.
Therefore, the first deck 12 does not immediately start the reproduction operation based on the reproduction switching signal, but starts the reproduction operation after the information reading from the auxiliary memory 70 is completed. For this purpose, the deck controller 30 controls the read driver 7
4 can receive a read end command.

In this way, the continuously input information can be reliably recorded by the first deck 12, the second deck 14, or the auxiliary memory 70, thereby reducing the discontinuity of the playback screen. can do.

At this time, the storage capacity of the auxiliary memory 70 is not so required. The rewinding time in the first and second decks 12 and 14 depends on the recording time. For example, in the case of triple speed recording, it is possible to rewind several tens of minutes in a few seconds. Therefore, the information stored in the auxiliary memory 70 is about several seconds to about several tens of seconds, and even if it is video information, the storage capacity is not so large.

(Third Embodiment) As shown in FIG. 9A, the apparatus of the first embodiment is a double deck
The present invention is applied to one videotape 10 on which is mounted, but is not limited thereto.

FIG. 9B shows a case where two video tape recorders 80 and 90 are connected to perform the above-mentioned "simultaneous recording / playback operation". In this case, in addition to the first deck 12, the deck control unit 30, the various operation keys 20 to 27, and the second video tape recorder 80, for example,
A first output terminal 82 for outputting a recording command to a second tape recorder 90 on which the deck 14 is mounted;
A second output terminal 84 for outputting a reproduction command.

As described above, the first and second decks 12, 1
4 are separately arranged in the first video tape recorder 80 and the second video tape recorder 90, respectively, by providing the deck control unit 30 in one of them, the same as in the first embodiment. "Simultaneous operation of recording and reproduction" can be performed.

Fourth Embodiment In the fourth embodiment, a first video tape recorder 110 equipped with a first deck 12 and a second video tape recorder 112 equipped with a second deck 14 are The control device 100 is connected to perform the “simultaneous recording / playback operation”. The video control device 100 outputs a recording command and a reproduction command to a first deck 110, and outputs a recording command and a reproduction command to a second video tape recorder 112. And a second output terminal 104 for performing the operation. The various operation keys 22 to 27 may be provided in the video control device 100 as shown in FIG. 9C, but use the operation keys provided in the first and second video tape recorders 110 and 112. It is also possible.

As described above, the above-mentioned “simultaneous recording / reproducing operation” can be performed only by connecting the video control device 100 to two ordinary video tape recorders 110 and 112.

The present invention is not limited to the above-described first to fourth embodiments, and various modifications can be made within the scope of the present invention. For example, in the embodiment shown in FIG. 1, the recording start position and the recording end position are set to the first and second positions.
Is recognized based on the tape count values of the first and second tape counters 16 and 18 provided in the decks 12 and 14, however, the present invention is not limited to this. For example, if the tape running position is recorded on the tape-shaped recording medium itself, the recording start position and the recording end position can be recognized by detecting the recording. Alternatively, if the recording start time and the recording time are known, the recording start position and the recording end position on the tape-shaped recording medium can be recognized by time or time control.

In the various embodiments described above, the present invention has been described with respect to "simultaneous operation of recording and reproduction" in a video tape recorder. However, even when music information is recorded on a magnetic tape or the like,
The invention is equally applicable. Therefore, the present invention is applicable to a cassette tape recorder equipped with a double deck.

Furthermore, the present invention is not necessarily limited to recording and reproduction on a tape-shaped recording medium, and the present invention is similarly applied to recording and reproduction on various storage media such as a disk-shaped storage medium. be able to. When the first and second recording media are the first and second disk-shaped recording media, the first and second recording / reproducing means perform the first and second recording / reproducing operations.
A rotary drive unit for rotatingly driving the disk-shaped recording medium; a reproducing head for reading information by scanning in the radial direction of the first and second disk-shaped recording media; and recording information by scanning in the radial direction in the same manner. And an information recording head. In this case, unlike the tape-shaped recording medium, it is not necessary to perform rewinding after the end of recording or reproduction, so that it is possible to realize smooth reproduction with almost no recording blank period or reproduction blank period. Become.

Further, the present invention is not limited to the one having two recording / reproducing means, and the “simultaneous recording / reproducing operation” of the present invention can be carried out using three or more recording / reproducing means. In the apparatus of the second embodiment, an auxiliary memory such as a semiconductor storage memory is prepared in addition to two decks, and the “simultaneous recording / playback operation” is performed using three recording media. However, three or more recording media of the same type are used. It is also possible to carry out using.

In the case of a tape-shaped recording medium, it is necessary to rewind after the reproduction or recording is completed. In this case, if the recording period is too short, the normal running and the fast rewind for performing the recording or the reproduction are repeatedly performed, so that a considerable load acts on the player. For this reason, it is preferable to perform control for invalidating the input from the reproduction start switch 22 unless a predetermined time has elapsed after the recording is started.

When two tape-shaped recording media are used, the recording or reproducing operation cannot be performed during the rewind time as described above. For this reason, a commercial inserted in the broadcast information may be detected, and rewinding may be performed during the commercial broadcast time. At this time, since the reproduction or recording switching timing can be known in advance, if a commercial is broadcast at a position close in time to the reproduction or recording switching timing, the rewind operation is performed during the commercial period. Things can be given priority.

In the first embodiment, the reproduction operation on the other deck is started immediately after the reproduction on one deck is completed in order to minimize the number of blank reproduction screens. However, the recording operation is prioritized. It is also possible to control so that In this case, the playback blank period becomes longer, but it is preferable to control the recording operation so as not to be interrupted when the recording is watched again later. The deck control unit 30 shown in FIG.
It is preferable to have a changeover switch for giving priority to the reproducing operation or the recording operation.
