Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape record pause device that temporarily stops a running tape during recording and playback by separating a pinch roller in contact with a capstan via a pause slider.

Conventionally, there is a so-called quick pause, in which tape running is instantaneously stopped when a pause button switch is operated during playback or recording.

This function is necessary during playback, but it is inconvenient during recording because there is no space left and the next recording starts.

Conventionally, in such cases, the method used was to manually feed the tape to take up space.

In addition, recently, a node has been developed that detects the blank time between sentences or words and repeats between sentences or words using a language training machine or the like.

However, in general, even if you have such hardware, when you create your own software, it is difficult to create a blank, so you don't actually create your own software.

Furthermore, when recording radio such as FM broadcasts, pauses are used when you want to eliminate unnecessary broadcasts such as commercials.
When recording the next song after a pause, it feels unnatural because there is no gap between the end of the previous song and the song sounds as if it were a continuation.

The purpose of the present invention is to eliminate the above-mentioned inconvenience,
To provide a tape recorder pause device capable of inserting recording blanks into a recording tape by relatively simple mechanical means.

The present invention provides a pose actuating member that is driven in deceleration rotation from a flywheel shaft via a gear group, an operating device for controlling rotation of the pose actuating member, and the pose actuating member drives a pose slider via a cam. The recording input switch is also opened and closed.

An embodiment of the present invention will be described below with reference to the drawings.

1 and 2, a head plate 9 is mounted on the chassis 1 and is slidable and lockable in the direction of a cassette (not shown) during playback and recording.

On the head plate 9, a head 10 and a pinch roller arm 11 to which a pinch roller 14 is rotatably attached are rotatably attached to a pinch roller arm shaft 12.

The pinch roller arm 11 is attached via a pinch roller spring 13 so that the pinch roller 14 comes into pressure contact with the capstan 6.

15 is a winding arm, 17 is a winding pulley for winding up the tape (not shown) that is fed out during playback and recording, and 16 is a winding roller 15a connected to the winding pulley 17 by a friction mechanism, which is a turntable. 25 is a spring for crimping.

2 is a flywheel bearing at the upper part of the flywheel 5, 3 is a flywheel bearing, and 4 is a flywheel bearing at the lower part of the flywheel 5.

The flywheel 5 is formed integrally with the flywheel shaft, and has a capstan 6 formed at its upper end.A gear 7 of a gear group 21 is formed on the upper surface of the flywheel 5, and a pulley 8 is provided on the lower surface. A belt 8a that transmits power from a motor (not shown) that rotates the motor 5 is stretched around the belt 8a.

A pose slider 19 has a guide hole 19b into which the guide pin 18 is loosely fitted, and is slidable in the direction of the guide hole 19b.The pose slider 28 normally causes the capstan 6 and the pinch roller 14 to come into contact with each other. It is attached and biased in the direction of

19f is an arm pin hole into which the arm pin 15b of the winding arm 15 is inserted, and the arm pin 15b is connected to the cam 19e.
is facing.

19a is a pose slider projection which operates the pinch roller arm 11 and separates the pinch roller 14 from the capstan 6 during a pause.

Further, the arm pin 15b contacts the cam 19e and pulls the winding roller 15a on the winding boob IJ 17 for winding the tape away from the turntable 25.

19d is a lever projection.

19g is an arm provided on the pose slider 19, and is provided with a pose slider cam contact surface 19c that faces and contacts cams 23f and 23g provided on the pose actuating member 23 (see also FIGS. 6 and 7).

20 is a gear shaft, and a gear 22 that meshes with the gear 7 gear 23h is fixed to the gear shaft 20.

Gears 7.21a and 22 constitute a gear group 21, which transmits the rotation of the axis of the flywheel 5 to the pause operation member 23.

The transmission speed is obtained by changing the gear ratio of each gear.

The pause operation member 23 is mainly composed of a giga 23h and a gear 23h.
A cam 23g rotates upward on the same shaft 24 as the cam 3h to contact the pose slider cam contact surface 19c and drive the pose slider 19 to separate the capstan 6 and the pinch roller 14, and the gear 23h is connected to the gear 23h. A cam 23f is provided in contact with the pause slider gum contact surface 19c in the rotational direction to apply a torque.

Also, on the bottom surface of the gear 23h, a recording input switch 44 is provided.
A cam 23e for opening and closing is provided.

As shown in FIG. 1, the gear 23h has toothless parts 23a and 23b located at <90° apart, and is rotated by a slider 26a between the toothless part 23b position and a position 900 degrees ahead of the toothless part 23b position. Pins 23 c and 23 d are provided at positions where they are blocked.

The slider 26a is attached so as to be drawn toward the pose actuating member 23 by a slider spring 29, has an operating portion 26a, and is slidably attached with a guide pin 27 loosely fitted into a guide hole 26b.

In FIGS. 5 to 7, 38 is a button of the operating device 45 for quick pause.

The button 38 is formed integrally with the button plate 37 and has an L that engages with the lever protrusion 19d of the pose slider 19 via the button plate 37.
It is connected to a letter-shaped lever 30.

The lever 30 is rotatably mounted via a lever fulcrum 31, and is rotatably mounted by combining an elongated hole with an operation pin 36 fixed to a button plate 37.

Reference numeral 33 denotes a lock arm, which is rotatably attached via a pin 34 that fits into a longitudinal groove (not shown) in the button plate 37.

35 is a lock pin. Reference numeral 32 denotes a spring attached to draw the lock arm 33 toward the stopper 32a.

The button plate 37 is held in the position shown in FIG. 6 by a spring (not shown).

The button 38, the button plate 37, and the lever 30 form a quick pause operating device 45.

When the button 38 is pressed, the button plate 37 is pressed as shown by the arrow 13 in FIG.
is displaced, the lever 30 connected to the button plate 37 rotates counterclockwise around the lever fulcrum 31, and the pose slider 19
The gear 21a and the pose actuating member 23 are placed on the gear 21a and the pause actuating member 23, which are engaged with each other to move in the direction A shown by the arrow in FIG.

Further, the lock arm 33 is rotated counterclockwise by the stopper 32a, and when the pin 35 is broken, it is brought to the position shown in FIG. 7 by the tension of the spring 32 and locks the button plate 3γ.

Further, 43 is a button for slow pose, which is integrally formed on the button plate 42, and the button plate 42 has an operation pin 41 inserted into a long hole at one end of an L-shaped lever 39 that rotates around the lever fulcrum 40. It is inserted and connected.

The other end of the lever 39 is engaged with the operating portion 26a of the slider 26c.

The button 43, the button plate 42, the lever 39, and the slider 26a form the slow-pause operating device 26.

When the button 43 is pressed, the lever 39 is rotated counterclockwise about the lever fulcrum 40, and the slider 26a is pulled in the direction of the arrow in FIG.

Next, we will discuss the effect of slow pose.

During recording, the head plate 9 slides on the chassis 1 in the direction of the cassette, and the head plate 9 is locked in a predetermined position as shown in FIG.

In this state, the tape is held between the capstan 6 and the pinch roller 14 and driven at a constant speed.

On the other hand, a winding roller 15a having a friction clutch mechanism for winding up the unwound tape is connected to a turntable 25.
The turntable 25 is driven to wind up the tape.

The pose operation member 23 is connected to the pose slider spring 2 by the pose slider cam contact surface 19c on the pose slider 19.
The cam 23f receives a tension of 8 and receives a torque in the direction of arrow C of a biasing force Fl.

However, the upper end of the slider 26c comes into contact with the pin 23c, locking the rotation of the pose actuating member 230.

In this state, the toothless portion 23a faces the gear 22,
The gear 23h portion does not mesh with the gear 22.

Next, when the button 43 is pressed during recording, the lever 39 is rotated counterclockwise in FIG. 8 to draw the slider 26c away from the pause actuating member 23 and remove it from the pin 23c.

Therefore, the pause operation member 23 rotates in the direction of arrow C, and this rotation also rotates the toothless portion 23a, causing the gear 23h to mesh with the gear 22, and being decelerated by the gear group 21, the rotation continues.

Due to this rotation, the cam 23g also rotates, and the pose slider 19 is displaced in the direction of arrow A due to the shape of the cam 23g, thereby moving the pinch roller 14 away from the capstan 6.

When the pause operation member 23 rotates and the toothless portion 23b comes into engagement with the gear 22, the pin 23d is prevented from rotating by the slider 26c, which has already returned to its original position.

Furthermore, the rotation of the pause operating member 230 causes the cam 23e to open the recording input switch 44.

The rotation angle during this time is assumed to be θ3.

In FIG. 4, 01 to θ5 indicate the rotation angles of the pause operation member 23, and θ1 is the rotation angle from the start of rotation until the recording input is cut off at this position.

θ2 is the rotation angle from when the button 43 is pressed until the tape drive stops, when the pinch roller 14 separates from the capstan 6,
At about the same time, the take-up roller 15a separates from the turntable 25, thereby stopping the tape running.

θ3 is the rotation angle from when the button 43 is pressed until it is locked, and the pin 23d is locked by the slider 26c.

In this state, the gear 22 is in the position shown in FIG.
b are opposed to each other, and a torque F2 in the direction of arrow C is applied to the pause actuating member 23.

θ4 is the rotation angle at which the tape starts running and the recording input switch 44 is turned on, and θ is the rotation angle when the tape rotates once (360').

The time t1 required for rotation from θ1 to 02 is the time the tape runs after the recording input is cut off.

Next, we will discuss when to release the slow pause.

When the button 43 is pressed, the slider 26c retreats and comes off the pin 23d in the above order, and the pause actuating member 23 rotates in the direction of arrow C.

As a result, when the gear 23h meshes with the gear 22 and rotates to θ4, the cam 23h releases the recording input switch 44.
At the same time, the pinch roller 14 and the winding arm 15, which were restrained by the pause slider 19, are released and the tape starts running again.

The pose actuating member 23 further rotates and stops at the position θ5 after one rotation when it hits the pin 23c on the slider 26c, resulting in the same state as before starting the pose.

Next, let's talk about a normal quick pose.

When the button 38 is pressed, the button plate 37 moves in the direction of arrow B in FIGS. 6 and 7, and the lever 30 moves to the lever fulcrum 31.
Rotate counterclockwise around the center.

The lock arm 33 rotates counterclockwise, and when the arc ends, it enters the inside and is locked.

The lever 30 moves the pose slider 19 in the direction of the arrow in FIG. 8 and stops in the state shown in FIG.

The displacement of the pause slider 19 causes the pinch roller 14 to move away from the capstan 6, and the tape stops running.

Further, in this state, the cam 23f and the pose slider cam contact surface 19c are provided so as to form a gap 1 as shown in FIG.

Therefore, in this state, no torque is generated in the pause operation member 23 in the rotational direction.

In addition, although the gear 22 has a toothless portion 23a facing the gear 22, even if the button 43 is pressed by mistake when locking the quick pose, no torque is applied to the pose actuating member 23, so a slow pose is not possible during the quick pose. It has become.

When the button 38 is further pressed, the lock pin 3 is closed by a well-known method.
5 is released from the lock arm 33, and by releasing the button 38, the pause is released and the tape runs again.

As described above, according to the present invention, the time delay of the pose as shown at t in FIG. 4 can be obtained by a relatively simple mechanism.

Therefore, by adding this time delay pause, you can easily edit language practice tapes, and you can also create spaces or gaps between songs, stories, etc. in radio broadcasts. , you can listen to it naturally without the misunderstanding that the song and story are continuing.

Furthermore, in the above embodiment, by providing the East Quick Pose together, a common slider etc. can be used and a pose suitable for the purpose can be selected.

Also, it is possible to easily prevent a slow pause malfunction during a quick pause.

The present invention is as described above, and has the effect of allowing recording blanks to be inserted into a recording tape by simple mechanical means.
