Description

[Detailed Description of the Invention] (A) Technical Field The present invention relates to an improvement of a synchronized recording device, and in particular controls the pause circuit of a tape recorder by moving the tone arm of a record player up and down, and This invention relates to an improvement of a synchronized recording device that can switch between a recording state and a recording pause state.

(b) Background of the Technology A synchronized recording device has been proposed that switches a tape recorder between a recording state and a stop state in conjunction with the movement of a tone arm of a record player. Such a synchronized recording device puts the tape recorder in a recording pause state, and when the tone arm of the record player descends to play the record, the recording pause is released, the tape recorder enters the recording state, and the performance ends. However, the tape recorder is brought to a halt when the tone arm enters the final groove of the record and makes a large displacement, or when the auto-return mechanism is activated to perform auto-return of the tone arm.

However, if a synchronized recording device such as the one described above is used to record the output of a programmable automatic music selection record player, the first selected song will finish playing, and the second selected song will start playing. This has the disadvantage that the tape recorder maintains the recording state even during the no-signal period until the start of the recording, leading to unnecessary tape consumption and the gap between recorded songs becoming very long. was.

Therefore, the same applicant as the present applicant proposed a synchronized recording device that switches the tape recorder between a recording state and a recording pause state according to the vertical movement of a tone arm without detecting the end of a record performance. This synchronized recording device differentiates the cue signal for moving the tone arm up and down, applies the differentiated pulse to the pause circuit of the tape recorder, and switches the tape recorder between a recording state and a recording pause state each time the differentiated pulse is applied. , the tape recorder is set to the recording state only while the record is being played. This synchronized recording device is better and easier to use than conventional ones, but it detects the end of a song by detecting the silent gap between songs and raises the tone arm. Because it is a song that is used to record only the second verse of a song, it was not possible to use it to record only the second verse of a song.

(C) Main points of the invention The present invention was created in view of the above points, and includes signals generated in response to the vertical movement of the tone arm (including cue signals for vertical movement of the tone arm).
A control circuit that generates a control signal by differentiating the rising and falling edges of the control circuit, a pause circuit of a tape recorder to which the output control signal of the control circuit is applied, and a switch inserted between the control circuit and the pause circuit. When necessary, the switch circuit is cut off to prevent the control signal from being applied to the pause circuit, thereby making it possible to perform partial recording.

(d) Embodiment Figure 1 shows an embodiment of the present invention.
2 is a cue signal generating circuit of a record player; 2 is a first differentiating circuit for differentiating the rising edge of the cue signal output from the cue signal generating circuit 1; and 3 is a second differentiating circuit for differentiating the falling edge of the cue signal. , 4 is an inverting circuit for inverting the output of the second differentiating circuit 3; 5 is an inhibiting circuit for preventing differential output from being generated when the tone arm is on the armrest;
6 is a tape recorder pause circuit; 7 is the first
A switching circuit consisting of a FET gate etc. is inserted between the common output point A of the differentiating circuit 2 and the inverting circuit 4 and the pause circuit 6, 8 is a push button circuit for controlling the switching circuit 7, and 9 is a push button circuit. a manual pause button that is associated with the push button circuit 8 and that manually controls the pause circuit 6;
By applying a signal generated during operation to the push button circuit 8, the push button circuit 8 generates a signal that turns the switch circuit 7 into a conductive state.

Next, the operation will be explained. It is assumed that the tone arm of the record player is on the armrest, and the tape recorder is in a recording pause state with an "H" signal applied from the pause circuit 6. Furthermore, since the tone arm is on the armrest, the inhibit circuit 5 is activated and the output point A is grounded by the inhibit circuit 5.

Now, in order to move the tone arm located at the armrest position to the record playing position, when the cue signal is set to "H" at time t ₀ , its rising edge is differentiated by the first differentiator circuit 2, and no differentiated pulse is generated at output point A. shall be. However, due to the action of the prohibition circuit 5, the differential pulse is not applied to the pause circuit 6, and the tape recorder maintains the recording pause state. The tone arm raised by the cue signal "H" is horizontally rotated by a horizontal drive means (not shown), and when the tip of the record stylus reaches above the introduction groove of the record at time _t1 , the tone arm is horizontally rotated. Then, as shown in FIG. 2A, the cue signal becomes "L" and the tone arm begins to descend. When the queue signal becomes "L", its falling edge is differentiated by the second differentiating circuit 3 and inverted by the inverting circuit 4. At that time, since the tone arm is not at the armrest position, the inhibition circuit 5 stops operating, and the output point A is in a state where it has no influence. Therefore, a pulse such as a in FIG. 2C is generated at the output point A, which is applied to the pause circuit 6.
Since the output becomes "L" as shown in FIG. 2D, the tape recorder enters the recording state and records the signal generated from the record player.

When the performance of the song ends and the cue signal becomes "H" in order to raise the tone arm at time _t2 , its rising edge is differentiated, and the first differentiating circuit 2 outputs b in Fig. 2 (b).
A pulse as shown in FIG. 1 is generated, which is applied to the pause circuit 6 from the output point A, and the output of the pause circuit 6 becomes "H", and the tape recorder enters the recording pause state. Further, the tone arm is raised by the cue signal "H", and then the tone arm moves to the playing position of the next song or returns to the arm rest position depending on the programming. If it is necessary to lower or raise the tone arm, for example, the queue signal becomes "L" at time _t3 ,
If the queue signal becomes "H" at time _t4 , differential pulses c and d are generated accordingly. Therefore, the output signal of the pause circuit 6 becomes "L" due to the differential pulse c, and becomes "H" due to the differential pulse d, so that the tape recorder is sequentially switched between the recording state and the recording pause state.

By the way, differential pulses a to d are generated only when the tone arm moves up or down.
Therefore, it is not possible to release the tape recorder from the recording pause in the middle of a song and put it into recording mode. Therefore, in the present invention, the switch circuit 7 is provided,
By manually operating the pushbutton circuit 8, the switch circuit 7 can be controlled, making it possible to perform special recording as described above. That is, if the switch circuit 7 is cut off by operating the push button circuit 8 before time _t1 when the differential pulse a is generated,
The differential pulse a is cut off by the switch circuit 7,
It is not applied to the pause circuit 6. Therefore, the tape recorder maintains the recording pause state and does not enter the recording state. As the performance of the song progresses and the pause is manually released when the desired part is reached, the tape recorder enters the recording state and can record the part after the desired part.

On the other hand, when the manual pause button 9 is operated to release the pause, a signal generated by the operation is applied to the push button circuit 8. Therefore, the push button circuit 8
The switch circuit 7 becomes conductive due to the signal generated from the switch circuit 7. Therefore, after the pause is released, the synchronized operation is restored without any special operation to make the switch circuit 7 conductive, and the performance of the song is completed and the tone arm is raised. The pulse b generated at this time can put the tape recorder into the recording pause state again.

(e) Effects As described above, according to the present invention, the signal generated in response to the vertical movement of the tone arm is not applied to the pause circuit by blocking the switch means, so that the performance of the record player can be improved. To provide a synchronized recording device which can release a pause regardless of the vertical movement of a tone arm and put a tape recorder into a recording state by operating a manual pause button when the tone arm reaches a desired recording part. Furthermore, the synchronized recording device according to the present invention associates a manual pause button with a push button circuit, so that when the switch means is in a cutoff state, operating the manual pause button brings the switch means into a conductive state. Therefore, after the pause is released, there is an advantage that the synchronized operation can be restored without any special operation of turning on the switch means.
