Abstract

PURPOSE:To eliminate the intermittent head of a music at recording, to form automatically an interblock for detecting inter-music and to avoid the intermission of music even when a disc is subject to temporary pause in the playing of the music by using one synchronizing signal line so as to attain the synchronizing recording/stop/pause. CONSTITUTION:The reproduction of a music signal is started after a time T1 from a time Te and the T1 is an interblock recording period to detect the inter-music of a tape recorder. When a pause switch 13 of a CD player is turned on in the timing Th, the output through the synchronizing signal line 11 is inverted, the motor is stopped to stop the music signal. In releasing the pause switch at a time Ti, the output of the line 11 is inverted to logical H to start the motor, the music signal is outputted after a time T2 and recorded. In this case, no head intermission is caused by retarding the leading of the music signal by the start time of the motor in the music. Thus, the condition is given to a microcomputer as a control means to distinguish it from the inter-music detection time T1.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention performs playback, pause, or stop operations of a compact disc player (hereinafter referred to as a CD player) in synchronization with a recording operation of a tape recorder. So-called synchronized recording, synchronized pause.

This relates to a compact disc player with a synchro stop function and a stationary tape recorder.

2. Description of the Related Art In recent years, CD players have made remarkable progress, and products with built-in CDs have appeared in tape 1/coders and car stereos.

When a CD player is built into a tape recorder, in order to improve operability, the CD player is automatically activated when the tape recorder is operated.
A so-called synchronized operation is generally performed to operate the player. FIG. 4 shows a conventional tape recorder with a built-in CD player. 1 is a CD player, 2 is a tape recorder, 3 is a playback switch of the CD player, 4 is a recording switch of the tape recorder, 6 is a playback switch 3. 1 is a control circuit that drives the recording switch 4, and 6 is a control circuit that drives the control circuit 5 ((
A synchronized recording switch issues commands, and 10 is a music signal line.

FIG. 5 shows a timing chart for explaining the operation of the conventional device. a is an operating waveform of the synchronized recording switch, b is an operating waveform of the recording switch 4, and C is an operating waveform of the playback switch 3. Now, when the synchronized recording switch 6 is turned on at timing Ta, the playback switch 3 and the recording switch 4 are closed by the operation of the control circuit 5, and the CD
A playback operation of the player 1 and a recording operation of the tape recorder 2 are performed, and at the same time, a recording signal is supplied to the tape recorder 2, so-called synchronized recording is started. Next, when the recording switch 4 of the tape recorder 2 is released at the time of typing Tb, the tape recorder 2 is stopped, but C
D player 1 will continue to play.

Problems to be Solved by the Invention However, as is clear from FIG. 6, in the conventional device, when the synchronized recording switch 6 is closed, recording starts from the first track on the CD player 1, but the tape recorder 2 is recorded with a time delay. There was a problem that the beginning of the song would be cut off before the song started. There is still a problem that recording always starts from the first track on CD player 1, and a tape recorder still requires a 4-second gap between songs to accurately detect the song interval, but when the song on CD player 1 The inter-track time is about 3 seconds, and when continuous recording is performed, the inter-track time of the CD player 1 is recorded as it is, and there is a problem that the tape recorder cannot accurately detect the inter-track interval. Furthermore, when the recording switch of the tape recorder 2 is released as described above, the tape recorder 2 comes to a stop state, but there is a problem in that it is not possible to perform so-called synchronized stop or synchronized pause, in which the CD continues to play.

Means to Solve the Problems The tape recorder with built-in compact disc player of the present invention is equipped with a recording switch for creating a recording standby state on the tape recorder side, and connects the CD player and tape recorder with the same 1tJi signal line. Recording of tape 1/coder is performed using synchronization signals, which are high and low signals linked to the CD player's play, pause, and stop switches.
It is characterized by being able to pause and stop.

Effects of the present invention With the above-described configuration, when the tape recorder closes the recording standby switch, synchronized recording can be performed simply by turning on the playback switch of the CD player, and when the pause switch of the CD player is closed. The motor of the tape recorder is temporarily stopped to enter a recording standby state, and when the stop switch of the CD player is closed, the tape recorder is also stopped, so-called synchronized recording, synchronized pause, and synchronized stop functions can be realized. Further, a $ control means on the CD player side provides a constant timing between the synchronization signal and the music signal,
This eliminates the cut-off at the beginning of a song or when restarting after a pause, and there is always about 4 seconds of no signal between songs. 1. Not only the first song but also the same song is selected by the CD player by the skip operation, and during the song selection, the tape recorder is in recording standby mode, and after selecting the song, the CD player is in the recording standby state.
By closing the playback switch of the D player, synchronized recording can be performed from any number of songs.

Embodiment FIG. 1 is a block diagram of the present invention, FIG. 2 is a timing chart 1 for explaining its operation, and FIG. 3 is a flowchart of a microcomputer that implements the process shown in FIG. In FIG. 1, the same numbers as in FIG. 4 are the same constituent elements, and their explanation will be omitted. 11 is the synchronization signal line, 12 is the CD player 1
13 is a pause switch of the CD player 1, and 14 is a recording standby switch. In FIG. 2, a is the operating waveform of the recording standby switch 14, b is the operating waveform of the playback switch 3 of the CD player, C is the operating waveform of the synchronization signal line 11, d is the voltage waveform applied to the motor of the tape recorder 2, and e is the operating waveform of the playback switch 3 of the CD player. Operation waveform of music signal line 10, f
is an operation waveform during the pause period A.13 of the CD player. g indicates the operating mode section, 22 is the stopped state,
23 is the RIC stand/dead state, 24 is the CD player's axle 1, and 25.29 is the tape recorder's seventh position.
During the evening start-up period, 26.31, there was no signal recorded for 7'51υ1,
27, 30, 32 (d must arrive signal recording period, 28 is a pause period.

Now, suppose that the recording standby switch 14 is closed at time Tc and the recording standby υ1 state 23 is entered. accesses 111b and reaches 0 minutes 0 seconds at the beginning time Te of the first song, the signal on the synchronization signal line 11 is inverted from L to H,
The motor of the tape recorder 2 starts rotating due to the reversal, and at time Tf, the number of revolutions of the municipal motor reaches one revolution. ^1 The reproduction of the music signal is started after a time T1 from the time Te of the construction record, and the time T1 becomes the silent speech recording period.
If possible, turn on the tape recorder's inter-track detection. 27 is a music signal recording period. , at the timing of Th,
When the pause switch 13 of the CD player is turned on, the same 1
The output of the υ1 signal line 11 is inverted and becomes L, and the output also causes the motor to stop and the music signal to stop as well.Fourth time, at time T1, if you release the pause button,
The output of the synchronizing signal line 11 is inverted to H and the motor is activated by the output, and after time T2, a music signal is output and recorded. At this time, if the song is in progress, the start of the music signal is delayed by the motor activation time, thereby preventing any cut-off at the beginning of the song. Therefore, this condition is given to a microcomputer as a control means to distinguish it from the time T1 of the inter-musical detection. When the first song ends and the beginning of the second song is detected, 0 minutes and 0 seconds are detected, a no-signal section is created for a period of time T1 between songs. The output of the synchronization signal line 11 changes from L to H
FIG. 3 is a flowchart of the microcomputer which determines the setting time of T1, where the period between )01 at J-, where the music signal is outputted to the music signal 'η10 after switching to the music signal 'η10, is defined as T1. 'r2=o, 6 seconds is applied during a pause during a song to absorb the delay in motor startup time. T1-4 seconds is applied when obtaining the time for detecting between songs. As explained above, if you select the beginning of a song using the nudging motion of a CD player, the same thing can be said from any number of songs.

Effects of the Invention According to the present invention, synchronized recording, synchronized stop, and synchronized pause of a tape recorder with a built-in CD player can be performed using a single synchronizing signal line, eliminating the need to cut off the beginning of a song during recording. No-signal sections between songs are automatically created, and even if the song is paused, the song can be recorded without interruption.
