PURPOSE:To prevent the miscontrol of a tape recorder due to a record player owing to the change of a recording source of the tape recorder, by inhibiting the 2nd signal which is produced in response to the action of a tone arm driving means in case an action stop control signal is impressed from an amplifier. CONSTITUTION:An inhibition means FF-3 inhibits the 2nd signal produced by a 2nd signal generating means 114 in response to an action stop control signal in case the action control signal is impressed from an amplifier connected with a record player. In this way, the miscontrol of a tape recorder due to a record player owing to the change of a recoring source of the tape recorder is prevented.

Description

[Detailed Description of the Invention] (a) The field of industrial application is based on a player L2 lock, and in particular, it relates to a record player equipped with a synchronized recording function. .

(b) Conventional technology Conventionally, when recording a signal reproduced from a record player with a tape recorder, the tape recorder is placed in a ``bose'' state prior to the start operation of the record player, and then simultaneously with the start operation of the record player. It is necessary to release the Bose state, which makes the operation complicated.

As a way to solve this problem, for example,
Those disclosed in Japanese Patent Application Laid-open No. 9251 and Japanese Patent Application Laid-Open No. 55-8674 are known.

(C) Problems to be Solved by the Invention The above-mentioned prior art relates to operational control only between a record player and a tape recorder, and this technology is applied to an audio system equipped with an auto-function function that has been proposed in recent years. If this happens, the following problems will occur.

That is, when synchronized recording is performed between the record player and the tape recorder, the recording fi of the tape recorder is
When the tuner's selection button is operated in order to change from a record player to, for example, a tuner, the amplifier function is automatically switched to a tuner selection state and the record player enters a cut operation state. In this way, when the chord player enters the cut operation state, a control signal is sent to stop or pause the table recorder in connection with the drive of the 1-arm, and a signal from the tuner is requested to be recorded. There is a problem in that the tape recorder stops or temporarily stops even though the tape recorder is in use.

(d) Means for solving the problem First signal generating means for generating a first signal of a predetermined width in response to a start operation; a second signal generating means for generating a narrow second signal; and a gate means to which the first and second signals are applied; the first and second signals are selected by the control means of the tape recorder via the gate means. In the record player, when the operation stop control signal is applied from the amplifier to which the record player is connected, the second signal generating means is configured to control the operation of the tape recorder by applying the operation stop control signal to the record player. A prohibition means for prohibiting generation of the second signal is provided.

(E) Effect In the above configuration, when the operation stop control signal is applied from the amplifier, this control signal is applied to the tone arm driving means to operate the tone arm driving means to perform a cutting operation and also to respond to this control signal. The inhibiting output of the inhibiting means activated by the inhibiting means is applied to the second signal generating means, thereby acting to inhibit generation of the second signal.

(114) is a second pulse generating circuit that generates a pulse in response to the closing of a switch (95) provided near Okia (1), and (OR-1) is a second pulse generating circuit (114 ) and a flip-flop (FF-1>).The output is used as a synchronization signal with the cassette tape deck.

Next, the operation of the record player having such a configuration according to the present invention will be explained.

(1) Court lead-in In the circuit shown in Figure 7, when the start/cut switch (Sl) is operated (opened), the NAND gate (NA
ND-2) are both at H level (Flip-flop (FF-2) is reset by the initial pulse from the power supply when the power is turned on).
The gate (NAND-2) outputs an L level signal (see FIG. 8(d)).

In this way, the output signal of the NAND gate (NAND-2>
When the level is reached, the 1 of the NAND gate (NAND-1)
Since human power is at H level, NAND gate (NAND-
1) Output a +H level signal and connect the flip-flop (F
F-2> (see FIGS. 8(g) and (n)).

When the flip-flop (FF-2) is set in this way, the Q output (H level) of the flip-flop (FF-2) is applied to the first pulse generation circuit (112), and the first
A pulse is generated by the pulse generating circuit (112) (see FIG. 8<p)). Such a pulse is generated by a plunger (113
), and the plunger (113) is energized. Therefore, the start/cut lever (40) is moved in the direction of arrow C at plunge ~- (113). The Q output of the reject flip-flop (FF-2> is also applied to the OR gate (OR-4), and the output of the OR gate <0R-
4) outputs an H level signal, and operates a muting circuit (not shown) with this H level signal.

Also, the L level output signal of the NAND gate (NAND-2) is connected to the ground potential (IV'+) via the inverter (IV'+).
Since it is at L level, the NAND gate (NAND-1)
outputs an H level signal, and the flip-flop (FF-1
> (see Figures 8(C) and (m)). The H level signal from the Q terminal of the flip-flop (FF-1) is applied to, for example, a cassette tape deck via an OR gate (OR-1), and becomes a synchronization signal between the record player and the cassette tape deck. By the way, when the plunger (113) is energized and the start/cut lever (40) moves in the direction of arrow C, the switch drive member (30) comes into contact with the tip (41) of the start/cut lever (40). At the same time, press the trigger lever (2) with the pressing part (40a) of the start/cut lever (<40), and then press the trigger lever (2).
Rotate in the direction of arrow G.

In this way, the tip (41) of the start/cut lever (40)
> When the contact piece (30a) of the switch drive member (30) is pressed, the switch drive member (30) is pressed against the spring (32).
It is rotated in the direction of the arrow against the urging force of. When the switch driving member (30) rotates in the direction indicated by the arrow in this manner, the regulation of the first switch lever (50) by the switch driving member (30) is released, so that the switch (3) ON
When the motor drive circuit (not shown) is closed, the small gear (93) rotates.

By the way, at this time, the arrow G'' of the trigger lever '-(2)
) Due to the rotation in the J direction, the first and second levers (91) and (92) on the large gear (1) are moved in the direction of arrow E in FIG. 3. Therefore, the raised part (91a) of the second lever (91) engages with the claw part (93a) of the small gear (93), thereby rotating the large gear (1).

When the large gear (1) rotates in this manner, the guide lever (94) that slides on the cam surface (1b) of the large gear (1) rotates in the direction of arrow H against the urging force of the spring, and the switch is rotated. (95) is turned ON. When the switch (95) is turned on, the H level signal from the power supply (10B) is sent to the OR gate (OR-3).
The OR gate (OR-3> outputs an H level signal. The H level signal is applied to the first pulse generating circuit (112), and the first pulse generating circuit (112) outputs an H level signal.
112), the output of pulses is prohibited. The H level signal continues during the period when the switch (95) is ON (that is, during the period when the mechanism is operating due to the rotation of the large gear (1)) (Fig. 8(b)).
reference).

When the large gear (1) rotates, a sliding plate (1) having a bin (11) that follows the cam groove (1a) of the large gear (1)
0) slides in the direction of arrow F. When the sliding plate (lO) slides in the direction of arrow F, the operation selection lever (15) and the contact lever (60) come into contact with each other, causing the contact lever (60) to rotate in the direction of arrow 1. Arrow 1 of such a contact lever (60)
The first plate is attached to the lower surface of the sliding plate (10) by rotating in the direction.
Rotation: The bar (16) rotates. 1st rotation lever (1
6), the second rotating lever (17), which is integrally attached with a screw (20), also rotates in the force direction. At this time, the pink 17a installed on the second rotation lever (17)
) through the through hole (18b) provided in the third rotation lever (18).
), so the third rotating lever (18)
is rotated counterclockwise. That is, the cutout (18a) of the third rotating lever (18) is connected to the tone arm lever (
80) is rotated to a position where it can come into contact with the engagement pin (80b) provided on the shaft.

Therefore, the sliding plate (lO) starts sliding in the direction of arrow P,
When the cut-out portion (18a) comes into contact with the engaging pin (80b), the tone arm lever (80) is rotated counterclockwise, and the lead-in operation of the tone arm is performed.

By the way, the cam surface (69
The cam body (69) having b) is rotationally driven by a cam surface (12) formed on the side surface of the sliding plate (10).

That is, when the sliding plate (10) slides in the direction of arrow F, a cueing up operation is performed, and when it slides in the direction of arrow F, a cuing down operation is performed.

In addition, the record size selection levers (65) and (66) are also driven by the cam surface (12) of the sliding plate (10), and by sliding in the direction of arrow F, the protrusion of the record size setting lever (67) (
67a), and by contacting the bin (80c) of the tone arm lever (80) at this position, the tone arm is rotated to the position where it makes contact with the bottle (80c) of the tone arm lever (80).
By the way, as the mechanism progresses, the guide lever (94) moves into the recess (1b) of the large gear (1). lb
'), that is, when the rotation of the large gear (1) returns to the initial state where it has stopped), the pressure on the switch (95) by the guide lever (94) is released and the switch (95) turns OFF ( (See Figure 8(b)). Switch like this (
95) is turned off, the signal from the switch (95) is applied via the inverter <IV2).
An H level signal is output from the R gate (OR-2) (
8r5A(i)). The H level signal to decline is applied to the reset input terminals of the flip-flops (FF-1) (FF-2), and the flip-flops (FF-1) (FF-2)
2> (see FIGS. 8(m) and (n)).

Therefore, the output signal of the OR gate (OR-1) to which the Q output of the flip-flop (FF-1) is applied falls (see FIG. 8(h)). At the fall of the output signal of the OR gate (OR-1), the pause of the connected cassette tape deck is released and synchronized recording is started.

Further, the output signal of the OR gate (OR-4) to which the Q output of the flip-flop (FF-2) is applied also falls, and muting is canceled (see FIGS. 8(k) and (r)).

(i) Auto Return After the auto lead-in operation described in (i) above, the record player continues to play the record, and when the playback stylus reaches the innermost groove (lead-out groove), the tone arm lever ( 80) pin (80d) is tricale/<-
(2) and rotate the trigger lever (2) in the direction of arrow G. Therefore, in the same way as in the case of the auto lead 7 mentioned above, move the first and second levers (91 and 92) to the trigger lever (2) in the direction of arrow E, and cut and release the second lever (91). (91a) and the claw part (9) of the small gear (93).
3a), the large gear (1) is rotated.

When the large gear (1) rotates in this manner, the guide lever (94) that slides on the cam surface (1b) of the large gear (1) rotates in the direction of arrow H, turning on the switch (95). switch(
95) is turned on, an H level signal is sent from the power supply (10B) to the second pulse generation circuit (10B) via the cut-off switch (95).
114), and a pulse is output from the second pulse generating circuit (114) (see FIG. 8(Q)). The reject pulse is applied to the cassette tape deck through the OR gate (OR-1), thereby stopping or pausing the cassette tape deck in the recording mode.

Furthermore, the rotation of the large gear (1) causes the sliding plate (10) to slide in the direction of arrow F. However, at this time, since the tone arm lever (80) is rotating counterclockwise from the stopped state shown in FIG. It is rotated in direction B. As the operation determination lever (61) rotates in the direction of arrow B, the operation selection lever (15) is rotated counterclockwise by the shaft (61a) installed in the operation determination lever (61). It is in the lead-out operation selection position.

Now, when playing a record, the engagement pin (80b) of the tone arm lever (80) faces the cutout (14) of the sliding plate (10) in the vicinity thereof. Therefore, by sliding the sliding plate (10) in the direction of arrow F, the tone arm lever (80) is rotated clockwise in FIG. 2, and the tone arm lead-out operation is performed. is returned to the rest position.

At this time, the cam body (69) is rotated as in the case of the auto lead-in operation described above, and the tone arm is in the raised position.

By the way, when the cam body (69) is rotated, the cam body (69)
9) The light shielding plate (100) installed in 1 also rotates together (see Figures 5 and 6).Such rotation is detected by a sensor (photocoupler) (103), and cam body <6
9) is rotated by 9 degrees from the position corresponding to the lowest position of the toe arm, the sensor (103) outputs an H level signal.

The H level signal from the sensor (103) is applied to the muting circuit via an OR gate (OR-4>) to mute the left and right channel signals of the pickup.

Such muting is performed when the tone arm is in the rest position.

Now, as mentioned above, since the operation selection lever (15) is in the lead-out operation selection position, the arrow F on the sliding plate (10)
Contact with the operation selection lever (15) when sliding in the direction /-
- The receiving part (60a> of (60) does not engage. Therefore, the third rotating lever (18) rotates to the position where it abuts the engagement pin (80b) of the trigger lever lever 80). As a result, the lead-in operation is not performed when the sliding plate (10) slides in the direction of arrow F. Then, when the sliding plate (10) finishes sliding in the direction of arrow V, the cam body (69) rotates and the tone arm descends to the rest position, and the switch (3) is turned OFF and the lead-out operation is started. finish.

(i) Cut operation After the lead-in operation explained in section (1) is completed, press the start/cut switch (S) of the record player that is in the playing state.
+), the L level signal is output from the NAND gate (NAND-2), and the NAND gate (NAND
−1) (see Figure 8(a)(d)(g))
, Therefore, an H level signal G is applied from the NAND gate (NAND-1) to the set input terminal of the flip-flop (FF-2'), and the flip-flop (FF-2) is set (see FIG. 8(n). See page>

When the flip-prop (FF-2> is set in this way, the Q output (H level) of the flip-prop (FF-2)
is applied to the first pulse generating circuit (112), so that the first pulse generating circuit (112) generates 7 pulses (see FIGS. 8(n) and (q)). Such a pulse is applied to plunge ~-(113) and plunge ~-(113)
Turn on the power and move the start/cut lever (40) in the direction of arrow C.

Also, when the start/cut lever (40) is slid in the direction of arrow C, the suppressing part (
40g), press the trigger lever (2) and rotate the trigger lever (2) in the direction of arrow G.

By rotating the trigger lever (2) in the direction of arrow G, the first
The second lever (91) (92) moves in the direction of arrow E, and the cut-out (91a) of the second lever (91) and the small gear <93)
The large gear (1) is engaged with the claw part (93a) of the
rotates. This rotation of the large gear (1) causes the tone arm to rotate to the rest position, similar to the auto-return operation described in section (i).

By the way, the Q output of the flip-flop (FF-2> is O
It is also applied to the R gate (OR-4), and the pick-up output is muted by the H level signal from the OR gate 1-(OR-4).Now, the large gear (1 ), the switch (95) is turned on by the guide lever (94), so the second pulse generating circuit (1
14) A pulse is generated.

This pulse is applied to the cassette tape deck through the OR gate (OR-1>), and at its rising edge, the cassette tape deck is stopped from the recording mode or set to the Bose mode.

As the large gear (1) continues to rotate, the guide lever (94)
is the recess (1) of the cam surface (1b) provided on the large gear (1).
b'), the switch (95) turns OFF,
Flip-flops (FF-1) (FF-2>) are reset (see FIG. 8(b), (m), and (n)).

When the flip-flop (FF-2) is reset in this way, its Q output falls, so the output of the OR gate (OR-4) also goes to L level, and muting is canceled.

(jv) Return operation by signal from amplifier (i)
After the auto lead-in operation explained in section 1, as soon as the control signal from the amplifier is applied to the record player in the playback state (see FIG. 9(a)), the second bypass means (111) becomes conductive and the inverter Drop the input end of (IV3) to ground level (L level). Therefore, NAND gate (N
AND-4) (7) 1 human signal becomes l (L, bell,
At this time, since the external power signal is at H level, the output signal of the NAND gate (NAND-4> becomes L level, and after this LL-bell signal is inverted to H level by the inverter (IV4), An input signal is input to the set input terminal of FF-3>, and the clip flop (FF-3> is set (see FIGS. 9(e) and 9(n)).

On the other hand, the L level signal of the NAND gate (NAND-4> is also applied to the NAND gate (NAND-1), setting the flip-flop (FF-2) (see Figure 9 (m)). Therefore, the flip-flop (FF-
2) Q output (H level) is output from the first pulse generation circuit (11
2) Generate a pulse (see FIG. 9(o)).

At the same time, the Q output of the flip-flop (FF-2> is applied to the OR gate (OR-4>), which turns it off.
Muting is applied to the output of 4).

When such a pulse is applied to the plunge ~-(113), the plunge =-(113) becomes energized,
Move the start/cut lever (40) in the direction of arrow C.

When the start/cut tray/<-(40) moves in the direction of arrow C in this manner, the large gear (1) rotates as explained in section (i) (i) above, and the tone arm lever rotates to the rest position. I can move.

Also, when the large gear (1) rotates, the guide lever (94
), turn on the -〇 switch (95〉), and turn on the switch (
The H level signal from the second pulse generating circuit (1
14), but at this time the clip-flop (F
F-3) is fully set, and the clip-flop (FF
-3) Q output (H level) of the second pulse generation circuit (1
14), the second pulse generation circuit (11)
4), no pulse is generated and the OR gate (OR-1
) does not output an H level signal, so cassette 1 to tape deck are not subject to equivalent control.
n) (see p)).

As the large gear (1) continues to rotate and the guide lever (94) reaches the recess (lb') in the cam surface (1b), the switch (
95) is turned OFF. In this way, the switch (95) is turned OFF.
When it comes to F, one person 71 in OR game 1-(OR-2) becomes H.
level, the output signal of the OR gate <0R-2) becomes H level, and this H level signal is applied to the reset terminal of the flip-flop (FF-1>(FF-2)). FF-1) (FF-2>
is 'J(=t) (see Figure 9(It)(m)).

Therefore, the output signal of the OR gate (OR-4>) to which the Q output of the flip-flop (FF-2) is applied falls, and muting is canceled.

(v') Manual queuing up/down 2nd
When the cueing lever (73) is rotated in the stopped (playing) state shown in the figure, the rotating member (72) is activated by the spring (
The cam body (6) rotates due to the urging force of the cam body (6
9) is rotated in the direction of arrow J to enter the rising state (queuing up). By the way, the light shielding plate (100) is attached to the Kamui book (69), and the light shielding plate (100)
) is placed between the light emitting element and the light receiving element of the sensor (103), so it emits light when the cam body (69) is located at the position corresponding to the lowest position of the tone arm (S) during cueing town. Since the amount of light that can be emitted from the element is set slightly lower than the conduction level of the light receiving element, the cam body (69
) is small, the light-receiving element becomes conductive with just one rotation, and the sensor (103) outputs an H-level signal. This H-level signal is applied to the OR gate (OR-4), and muting is applied. .

Such muting is continued until the cam body (69) reaches a position corresponding to the lowest position of the tone arm by a cueing down operation.

(G) Effects of the Invention According to the present invention, when the operation stop control signal is applied from the amplifier, generation of the second signal that can be generated in connection with the operation of the tone arm driving means is prohibited. It is possible to prevent the record player from erroneously controlling the tape recorder due to a change in the recording source of the tape recorder, which has conventionally occurred.
