(2)2. (N) 3 with device numbers 1, 2, respectively. It is assumed that the recording-only device 4 is also set to a device number that does not overlap with the playback-only device. control 1
The command from 115 is applied to all playback-only machines and recording-only machine 4 with the same control signal, but the controller 5 always specifies the device number and issues an operation command or mode response request to identify the target device. and other devices can be distinguished and controlled.

In addition, it is assumed that the playback tape (1) is installed in the playback-only machine (1), the playback tape (2) is installed in the playback-only machine (2), and the playback tape (N) is installed in the playback-only machine (N). .

First, the user plays the playback tapes (1), (2), (N).
The necessary music signals are checked from among them, and the equipment numbers and song numbers in which each music signal exists are inputted into the input means 15b of the controller 5 in the order desired for dubbing, and programmed into the microcomputer 15c. For example, if the first step is the 1st song of device number (1), the second step is the 5th song of device number (2), and the G step is the Mth song of device number (N>), the first step is [1]
, [MACHINEI.

[1], [ENTER], and [5] as the second step.

[MACHINEl, [2], [ENTER], [M], [MACHINE], [N] as G-th step.

Enter [ENTER]. Then, the song number and equipment number of each step are stored in the microcomputer 15c as shown in FIG.

Next, the user operates [RFC] to start a dubbing operation, and from then on, editing operations are automatically executed. It is assumed that the microcomputer 15c is configured to determine that an operation of the [REC] key after inputting a program is a dubbing command.

Through the above operations, the controller 5 first determines the device number and song number of the first step, that is, the device number (1) and the song number (
1) is read from the memory and commands the playback-only device (1) 1 with device number (1) to search for the first song. The reproduction-only device (1) 1 receives a command from the controller 5 and searches for the first song using the song number search means 1b. - The first track number search is performed using the PNO-ID and start ID recorded on the tape. When the search is completed, the reproduction operation mode replying means 1a replies to the control 1115 that the operation has ended.

Next, the controller 5 outputs a one-track playback start command to the playback-only machine 0)1 in order to send a recording start command to the record-only machine 4.

The recording-only device 4 enters a recording operation using the recording means 4b, and the reproduction-only device (1) 11 enters a one-piece reproducing operation using the one-piece reproducing means IC. When the playback-only device (1) 11 detects a skip ID or a silent playback portion longer than a predetermined time, it determines that it is the end point of the song, stops the playback operation of the first song, and controls the playback operation mode response means 1a to end the operation. Reply to 5. Upon completion of the reproduction of the first song, the controller 5 instructs the recording device 4 to stop recording, and further issues a silent recording instruction. After performing silent recording for a predetermined period of time, the recording-only device 4 sends a response to the controller 15 indicating the end of the operation using the recording operation mode response means.

In this way, the first song on the playback tape (1) is dubbed as the first song on the recording tape.

Next, the controller 15 sets the program step counter to 2 and uses the data of the second step to set the playback tape (2) to 5 of the playback tape (2) in the same way as described above for the playback-only machine c2) 2 and the recording-only machine 4 with the device number (2). Dubbing the song as the second song on the recording tape.

Hereinafter, the playback tape (
Dub the Mth song of N) as the 6th song on the recording tape.

In this way, the controller 5 repeats the same dubbing operation until the final step.

In this embodiment, the start and end of a song are specified by a start ID, a skip ID, or a silent playback section longer than a predetermined time, but as an alternative method, if an absolute time code is recorded on the tape, It is also possible to store and judge the start point and end point of each tape in the form of a corresponding absolute time code.

Effects of the Invention The present invention uses a plurality of playback-only machines, a recording-only machine, and one controller, sets different unique equipment numbers to the plurality of playback-only machines, and recording-only machines, and the control machine sets the equipment number. By issuing both operation commands and operation commands, it becomes possible to control multiple devices by simply connecting control lines, and as a result, music signals, etc. that are distributed across multiple tapes, can be easily, freely, and automatically integrated into one. It is possible to dub a book to tape, and the final result is a single, well-edited recorded tape.
