Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pause device for a tape recorder that temporarily stops a running tape during recording/playback.

The conventional technique is so-called quick pause, in which tape running is stopped instantaneously when a pause button (switch) is operated during playback and recording. This feature is
Although it is necessary during playback, there is an inconvenience that there is no space during recording and the next recording starts. Conventionally, in such cases, the method was to manually feed the tape to take up space. Recently, hardware has been developed that detects the spatial time between sentences or words and repeats between sentences (between words) using language practice machines and the like. However, even if you have such hardware, when you create your own software, you will have a hard time creating a blank, so you will not actually create your own software. Also, when recording radio such as FM broadcasts, pauses are used when you want to cut unnecessary broadcasts such as commercials, but when you pause and record the next song, there is no blank space between the end of the previous song and the pause is used. It sounds unnatural and as if the song is continuous. SUMMARY OF THE INVENTION An object of the present invention is to provide a pause device for a tape recorder that uses a relatively simple mechanism to temporarily stop a running tape, insert a blank, and record a specific signal during the blank. . The present invention provides a pinch roller in contact with a capstan that is separated via a pause slider to temporarily stop the running tape during recording and playback, and a pause actuating member that is rotationally driven from a flywheel shaft via a gear group. A second operating device is provided to control the rotation of the pause actuating member, and the pause actuating member drives the pose slider via the cam, opens and closes the recording input switch, and outputs a specific signal while the recording manual switch is open. It is configured to close and open a signal recording switch to be recorded.

An embodiment of the present invention will be described below with reference to the drawings. Figure 1,
In Fig. 2, 1 is a chassis, and on the chassis 1 are
A head plate 9 is attached which can slide and lock in the direction of a cassette (not shown) during playback and recording. head plate 9
A head 10 is fixed thereto, and a pinch roller arm 11 rotatably supporting a pinch roller 14 is rotatably attached via a pinch roller arm shaft 12. The pinch roller arm 11 is biased and attached to rotate toward the capstan 6 via a pinch roller spring 13, and when the pinch roller 14 is pressed against the capstan 6, it drives a tape (not shown). It's summery. 15 is a winding arm; 16 is a spring attached to the turntable 25 to urge the winding roller 15a; and 17 is a winding pulley connected to the winding roller 15a by a friction mechanism.

2 is the Dobe bearing of the flywheel 5, 3 is the flywheel holder,
4 is a lower bearing of the flywheel 5, and 6 is a capstan formed at the end of the shaft of the flywheel 5.

7 is a gear formed coaxially with the flywheel 5, and 8 is a belt that is rotated by a motor (not shown) to a pulley 8a integral with the flywheel 5.

A gear shaft 20 fixes a gear 21a and a gear 22 that mesh with the gear 7 coaxially.

Gear group 21 is formed by gear 7, gear 21a, and gear 22. 19 is the pose slider, pose slider 1
The pose slider protrusion 19a of 9 is the pinch roller arm 1.
1, and when the pose slider 19 is activated, the pose slider protrusion 19a separates the pinch roller arm 11 from the capstan 6.

The pose slider 19 is attached to the capstan 6 via a pose slider spring 28 which is always biased in a direction in which the pinch roller 14 comes into contact with the capstan 6. 19b
is a pose slider guide hole in which the pose slider 19 is guided by a guide pin 18 and slides in the longitudinal direction of the Bose slider guide hole 19.

15b is an arm pin of the winding arm 15, which faces the cam 19e on the pose slider 19.

Reference numeral 23 denotes a pause operation member, which is mainly composed of a gear, and a cam 23e1, a cam 23f, a cam 23g, and a cam j are fixed to the shaft 24 of the gear.

The cams 23e and 23j are attached to the lower surface and rotate to open and close the recording input switch 23h and the signal recording switch 231. Cam 23f23g
is attached to the upper surface, and when the pose slider 19 is in a non-operating state, the cam 23f is locked to the cam contact surface 19c of the pose slider 19 as shown in FIG. 1 and FIG. As shown in the figure, the locking point is formed so as to generate a torque on the cam 23f in the counterclockwise direction as shown by the arrow c. That is, the pose slider 19 is attracted by the tension of the Bose slider spring 28, the cam 23f receives this force, and therefore the pose actuating member 23 also receives this torque. The gear part of the pause operation member 23 is provided with toothless parts 23a and 23b at positions 90 degrees apart, a pin 23c is fixed at the position of the toothless part 23b, and a pin 23d is fixed at a position 900 degrees further than the pin 23c. It is set up. The recording input switch 23h and the signal recording switch 231 are inserted into the circuit shown in FIG. 11, and in FIG. 11, 45 is a microphone,
46 is an amplifier, 47 is a variable resistor, 48 is a head, 49 is a tape, 50 is a ground, and 51 is an AC power source.

As shown in Fig. 4, the recording input switch 23h is connected to the cam 23.
When the signal recording switch 231 is opened from θ1 to θ4 by e, the signal recording switch 231 is closed as shown in FIG. 11 by the cam 23j for T3 seconds after T2 seconds have elapsed after the recording switch 23h has been opened. . In Figure 4, θ1
is the rotation angle of the pause operation member 23 until the recording input is cut off, θ2 is the rotation angle of the pause operation member 23 until the tape drive stops, θ3 is the rotation angle of the pause operation member 23 when the pause is activated, and θ4 is the tape running again. This is the rotation angle at which the recording input switch 23h opens at the same time as the recording starts. t1 is the time from opening the recording input switch 23h to stopping the tape running, and is determined by the reduction ratio of the gear group 21. T2 turns on the signal recording switch 231 after the recording input switch 23h is opened.
T3 is the time until the circuit is closed, and T3 is the signal recording switch 231.
This is the time when the circuit is closed. In FIGS. 1, 5, and 8, the second operating device 26 includes a slider 26c, a lever 39, a button plate 42, and a button 43.

The slider 26c has a guide shaft 27 loosely fitted into an elongated slider guide hole 26b, and is attached to be slidable in the same direction as the pose slider 19, and when not in operation, one end is connected to the pin 23c by the tension of the slider spring 29. It is installed so that it locks on. One end of an L-shaped lever 39 that rotates around a lever fulcrum 40 is locked in the lever locking part 26a of the slider 26c, and the long hole at the other end of the lever 39 is connected to the operating pin 41 of the button plate 42. It is locked in.
Reference numeral 30 denotes a first operating device, which includes a pose slider lever protrusion 19d formed on the pose slider 19 and an L-shaped lever that rotates around a lever fulcrum 31, as shown in FIGS. 1, 5 to 7. 30a, a button plate 37, and a button 38.

The lever 30a has one end connected to the projection 19 for the lighter lever.
d, and an operating pin 36 fixed to a button plate 37 is engaged in a long hole at the other end. A lock arm 33 has an arm pin 34 inserted into a long hole (not shown) in a button plate 37, and one end of which is connected to a lever 30a by a lever spring 32.

35 is a lock pin, and 35a is a stopper.

Next, we will discuss the effect.

During recording, slide the chassis 1 in the direction of the force setting and press the head 10. The head plate 9 on which the pinch roller 14 etc. are attached is the first
It is locked in place as shown. In this state, the tape is held between the capstan 6 and the pinch roller 14 and is driven at a constant speed. On the other hand, a winding roller 15a having a friction clutch mechanism for winding up the tape that has been fed out presses against the turntable 25, drives the turntable 25, and winds up the tape. The speed is reduced by the gear 21a which is constantly engaged with the flywheel 5 and the gear 7 which rotates in the direction of arrow b.
The gear 22, which is fixed to the gear shaft 20 coaxial with and facing the toothless portion 23a of the pause operation member 23, is also rotating. The gear 22 faces the toothless portion 23a, but does not mesh with it. The pose actuating member 23 uses the pose slider cam contact surface 19c on the Bose slider 19 to apply the tension of the pose slider spring 28 to the cam 2 as described above.
3f, an eccentric force indicated by arrow F1, and a torque in the direction of arrow c.

However, the end of the slider 26c comes into contact with the pin 23c,
Rotation of the pause actuating member 23 is prevented. Next, the eighth
In the figure, when the button 43 of the second operating device 26 is pushed in the direction of the arrow, the lever 39 is rotated counterclockwise, and the slider 26
Move c in the direction of the arrow. Therefore, pin 23c comes off,
The pause actuating member 23 rotates in the direction of arrow c, and the toothless portion 23
As a rotates, the gear portion meshes with the gear 22 and is driven. Due to this rotation, the cam 23f also rotates, and the cam 23g
The pose slider 19 moves in the direction of arrow A depending on the shape. As shown in FIG.
When the pin 3b comes to a position facing the gear 22, another pin 23d contacts the slider 26c and is prevented from rotating. Pause actuation member 2
3 is explained with reference to FIG. 4. When the pin 23c is removed by the slider 26c, the pause actuating member 23 moves from the 0 position.
starts rotating in the direction of arrow c. When the rotation reaches θ1, the recording input switch 23h is opened. When the rotation reaches θ6 after T2 hours, the signal recording switch 231 is closed and the rotation reaches θ7.
A specific signal is recorded for a period of time T3. This signal can be made variable by changing the number of pulses or the pitch of the sound, and has the advantage that addresses can be easily detected.
In this signal recording, as shown in FIG. 12, the tape 52 advances as shown by the arrow, and after recording H,
The recording input switch 23h is opened at point C, the signal recording switch 231 is turned on at point D, and the signal recording switch 231 is turned on at point D, and the tape 5 is turned on at point E.
2 stops, and at the lower point the tape starts running again, the recording input switch 23h is closed, and recording G is started. Further, when the pose actuating member 23 rotates to θ2, the cam 23g rotates and the pose slider cam contact surface 19
c in the direction of arrow A in FIG. 1, the pinch roller 14 separates from the capstan 6, and at the same time, the take-up roller 15a separates from the turntable 25, thereby stopping the running of the tape 52.

When the pose actuating member 23 reaches the θ3 point, the pin 23d is locked by the slider 26c as described above. In this state, the cam contact surface 19e is in opposing contact with the cam 23g so as to generate a torque of F2. The time t1 required for rotation from θ1 to θ2 is the recording manual cut-off tape 52.
It's time to run. Next, we will discuss the case of cancellation.

Button 43. When is pressed, the slider 26c slides away from the pause actuating member 23 in the above order and is removed from the pin 23d. The pose actuating member 23 rotates in the direction of arrow c by a rotational moment due to an eccentric force F2. Due to this rotation, the toothed portion of the gear meshes with the gear 22, and is driven by the gear 22 to rotate. When the rotation angle of the pause operating member 23 reaches θ4, the input cutoff of the recording input switch 23h is released, and almost at the same time, the pinch roller 14 and the winding roller 15a, which were restrained by the pause slider 19, are released. Tape running starts again. The pose actuating member 23 further rotates and the pin 23 is attached to the slider 26c at the position θ5 after one rotation.
c comes into contact and stops. This state is the same as before the start of operation. Next, when the button 38 of the first operating device 30 is pressed,
The button plate 37 moves in the direction B, and the lever 30a rotates counterclockwise about the fulcrum 31 by the operation pin 36 of the button plate 37.

The lock arm 33 tries to rotate clockwise by the spring 32 using the arm pin 34 as a fulcrum, but is held in the position shown in FIG. 6 by the stopper 35a of the chassis 1. The lock arm 33 is rotated counterclockwise by the pin 35 on the button plate 37, and when the arc is broken, the spring force moves the lock arm 33 to the position shown in FIG. 7 and locks the button plate 37. At this time, the lever 30a acts on the pose slider lever protrusion 19d of the pose slider 19, moves the pose slider 19 in the direction of arrow A, and moves the lever 30a as shown in FIG.
The tape is restrained and stands still, and the tape stops running. In this state, a distance 1 is created between the cam 23f of the pose actuating member 23 and the pose slider cam contact surface 19c. Therefore, during operation with the first operating device 30, no rotational moment acts on the pause operation member 23, and the toothless portion 23
Since a is opposed to the gear 22, even if an attempt is made to operate the second operating device by mistake, the slider 26c moves, but the pose operating member 23 does not rotate and cannot be operated. If the button 38 is pressed again, the lock arm 33 is released from the lock pin 35, and by releasing the button 38, the pause is canceled and the tape starts running again.

As described above, the present invention can provide a pause time delay at low cost with a relatively simple mechanism, and can easily edit a tape for language practice.

Further, blanks can be appropriately created between songs, stories, etc. in radio broadcasts, etc., and recording can be performed without causing the misunderstanding that the songs or stories are continuous. Furthermore, while the recording input switch is cut off during a pause, the signal recording switch for recording a specific signal can be closed and opened, and the unrecorded section can have a specific signal section, which is convenient for use in address detection and other purposes. Furthermore, since the first operating device and the second operating device are arranged side by side using a common pose slider, it is possible to select a pose that suits the purpose and also reduce the number of parts. The present invention is as described above, and it is possible to pause a running tape and insert a pause time delay blank using a simple mechanism, and to record a specific signal during this blank. It has the following effects:
