Description

Description: TECHNICAL FIELD The present invention relates to a dubbing control device from a disc player to a tape recorder.

(Prior Art) Conventionally, there is known an automatic exchange type CD player that can select an arbitrary CD from a plurality of compact discs (hereinafter, referred to as CDs) and set the selected CD at a signal reproduction position. Have been.

In such a CD player, a plurality of desired songs can be sequentially reproduced from a plurality of CDs in accordance with a reproduction program set by a user, and the reproduced signal can be dubbed to a magnetic tape by a tape recorder.

In this case, if the time required to reproduce all songs to be dubbed is longer than the recordable time of one magnetic tape, dubbing over a plurality of magnetic tapes is required. At this time, it is desirable that the non-recorded portion generated at the end of each magnetic tape be as short as possible.

Therefore, conventionally, the most efficient reproduction order has been determined by comparing the reproduction time of each song to be dubbed by the user with the total recording time of the magnetic tape.

Also, when the CD needs to be replaced during dubbing, such as when the song to be dubbed extends over multiple CDs,
It is necessary to temporarily stop the recording operation of the tape recorder.

In such a case, conventionally, the user has manually stopped the tape recorder.

(Problems to be solved) In the conventional dubbing of a plurality of songs using an automatic exchange type CD player and a tape recorder, it is necessary for a user to set an optimal dubbing program and operate the tape recorder when exchanging a CD. The dubbing operation is extremely complicated. Further, when the dubbing program is poorly edited, there is a problem that a long unrecorded portion is formed on the magnetic tape and the use efficiency of the magnetic tape is deteriorated.

An object of the present invention is to automatically create an efficient dubbing program capable of reducing unrecorded portions generated on a magnetic tape as much as possible in dubbing music recorded on a plurality of disks to a magnetic tape. Still another object of the present invention is to provide a dubbing control device which can automatically set the tape recorder to a temporary stop mode during disk replacement.

(Means for Solving the Problems) A dubbing control device according to the present invention comprises: input means for setting recording time information W of a magnetic tape to be set in a tape recorder and a desired dubbing program; Reproduction time reading means (31) for reading reproduction time information R from the disc; recording time information W from the input means; and reproduction time information R from the reproduction time reading means (31).
Order selecting means (32) for editing an efficient dubbing program based on the information, and a reproducing control means (34) for controlling disc exchange and signal reproducing operation based on output information of the reproducing order selecting means (32). And a control signal generating means (33) for generating a control signal C for stopping the recording operation of the tape recorder during disc replacement and transmitting the control signal C to the tape recorder.

(Operation) First, the input means is operated to set the recording time of the magnetic tape and the dubbing program.

According to the dubbing program, one disk to be reproduced is set at the signal reproduction position, and as a result, the reproduction time reading means (31) reads the reproduction time information R from the disk.

The recording time information W set in the input means and the reproduction time information R read from the disc are sent to the reproduction order selection means (32).

The reproduction order selecting means (32) creates a dubbing program composed of, for example, a tune (video) to be dubbed and a large number of combinations having different reproduction orders, and from among the dubbing programs, the non-recorded portion of the magnetic tape is the shortest. The dubbing program is selected and this information is sent to the reproduction control means (34).

As a result, signal reproduction is started in accordance with the selected dubbing program, and disc exchange is performed as necessary.

The reproduced signal is sent to a tape recorder and recorded on a magnetic tape.

When the disc is exchanged during dubbing, a control signal C for stopping the recording operation during disc exchange is sent to the tape recorder by the control signal creation means (33).
After completion of the disk exchange, dubbing is started again.

For the music excluded from the dubbing program, the same dubbing process is performed after exchanging the magnetic tape.

(Effects of the Invention) According to the present invention, an efficient dubbing program that can reduce unrecorded portions generated on a magnetic tape as much as possible is automatically created, and the tape recorder is automatically paused when a disk is replaced. Therefore, the dubbing operation becomes extremely simple.

(Example) The example is intended to illustrate the present invention, and should not be construed as limiting the invention described in the claims or reducing the scope thereof.

FIGS. 1 and 2 show an example in which the dubbing control device according to the present invention is applied to an automatic exchangeable CD player.

The CD player (1) includes a CD changer (14) capable of selectively setting one CD (11) from a plurality of CDs to a drive shaft of a spindle motor (12) as is well known. The audio signal read from the set CD (11) by the pickup device (13) is transmitted to the tape recorder (2) via the signal reproducing circuit (4).

The operation of the CD changer (14) is controlled by a music selection circuit (5).

The spindle motor (12), pickup device (1
3) A main control circuit (3) including a microcomputer is provided to control the operations of the signal reproducing circuit (4), the music selecting circuit (5), and the tape recorder (2).

The main control circuit (3) is supplied with a reproduction end signal E from the signal reproduction circuit (4) and a mode signal M from the synchro-recording control circuit (8). An indicator (7) is connected. The end of reproduction of one disk is detected by the reproduction end signal E, and the operation state of the tape recorder (2) is detected by the mode signal M.

On the other hand, the tape recorder (2) is based on a device main body (21) composed of a tape running system, a signal recording system, and the like, and a control signal sent from a main control circuit (3) of the CD player (1). A synchro-recording control circuit (8) for controlling a recording operation synchronized with the reproduction signal.

According to the computer program set in the main control circuit (3), the reproduction time reading means (31) shown in FIG.
A playback order selection means (32), a control signal creation means (33), and a playback control means (34) are configured.

Hereinafter, the operation of the apparatus based on the computer program will be described with reference to the procedure shown in FIG.

At the time of dubbing, the user first operates the key input device (6) shown in FIG. 1 to input a plurality of songs to be dubbed in an arbitrary order, for example, a recording order on a CD.
As a result, a dubbing program as a first plan is created, and this information is sent from the main control circuit (3) to the music selection circuit (5).

Further, the user inputs the recording time of the magnetic tape set in the tape recorder (2) by a key together with the music selection operation.

CD changer according to the dubbing program (1
4) is controlled, and one disk to be reproduced first is set on the spindle motor (12).

Thereafter, after the completion of the setting of the disc is detected (FIG. 3 (9)), the signal reproduction of the time table provided on the signal surface of the disc is performed.
The playback time is sent to the playback time reading means (31) of the main control circuit (3), whereby the playback time of each music included in the dubbing program is read (FIG. 3 (91)).

The read reproduction time information R is sent to the reproduction order selection means (32) of the main control circuit (3) in FIG.

Next, after detecting that the recording time of the magnetic tape has been input (FIG. 3 (92)), the reproduction order selecting means (32) of the main control circuit (3) is set to the key input device (6). The most efficient dubbing program plan is created based on the recording time information W and the reproduction time information R (FIG. 3 (93)).
Then, this information is sent to the reproduction control means (34) and the display (7) in FIG.

Various well-known scheduling methods can be applied to create the most efficient dubbing program. For example, the recording order on the CD is initially set as the first plan, and the reproduction time is calculated while gradually changing the reproduction order from the first plan within a range not exceeding the recording time of the magnetic tape. A method of selecting a plan that makes the unrecorded portion shortest can be adopted.

As a result, the dubbing program plan is displayed as characters on the display (7).

The user inputs into the key input device (6) whether or not the dubbing program displayed on the display (7) is sufficient.

The main control circuit (3) determines whether or not the dubbing program plan is accepted based on the key input (third one).
(Fig. 95). If no, another dubbing program plan is created and displayed.

When the dubbing program proposal is accepted, the main control circuit (3) sets the dubbing mode (FIG. 3 (96)).
Then, a recording start command is sent to the synchro recording control circuit (8), and according to the accepted dubbing program,
Start playing the disc.

When the reproduction of one tune is completed (FIG. 3 (97)), it is determined whether or not the disk needs to be replaced (98). If the replacement is not necessary, the process proceeds to the reproduction of the next tune (102).

If it is determined that the disc needs to be replaced, the control signal generating means (33) shown in FIG. 2 sends a pause signal to the synchro recording control circuit (8) of the tape recorder (2) (see FIG.
9)) As a result, the recording operation of the tape recorder (2) is temporarily stopped.

After detecting the end of the disk exchange (FIG. 3 (100)), the main control circuit (3) sends a pause release signal to the sync recording control circuit (8) (FIG. 3 (101)). As a result, dubbing from the replaced disk is continued.

Thereafter, when the reproduction of all the songs included in the dubbing program ends (FIG. 3 (103)), the main control circuit (3)
Sends a stop signal to the sync recording control circuit (8) (FIG. 3, (104)), and ends the dubbing procedure.

If the magnetic tape to be set on the tape recorder (2) is a cassette tape that can be recorded on the A side and the B side, the unrecorded data for each side is specified in the creation of the dubbing program plan (93) in FIG. The dubbing program may be edited so that the portion is minimized.

If all songs to be dubbed have not been recorded on one magnetic tape, a new magnetic tape is set on the tape recorder, and then the above dubbing operation is repeated for unrecorded songs.

According to the above-mentioned dubbing control device, an efficient dubbing program capable of reducing unrecorded portions generated on the magnetic tape as much as possible is automatically created, and the tape recorder is automatically paused during disk replacement. Therefore, the dubbing operation becomes extremely simple.

The drawings and description of the above embodiments are intended to illustrate the present invention and should not be construed as limiting the invention described in the claims or reducing the scope thereof.

Further, the configuration of each part of the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made within the technical scope described in the claims.
