The present invention relates to an automatic reversing type tape recorder capable of facilitating fast forwarding and rewinding operations by manual operation.

If you have an automatic reversing tape recorder with a fast-forwarding feature, you typically send a tape quickly to the right (usually called the forward direction) and one operating member to the left (usually called the reverce direction). An operation member or the like is formed and these two operation members are used to quickly send the tape to the right or left direction.

In such a configuration, however, during the playback or recording operation, when the tape is to be driven at the same speed (or in the opposite direction) as the direction in which it is now traveling, the tape running direction at that time is checked, and then the driving direction is checked. There was a problem that it was necessary to judge which operation member to operate in accordance with the driving direction, and there was a problem that it was easy to misoperate. Also, during the playback or recording operation, the tape running direction was switched by manual operation before reaching the end of the tape. In addition, if the number of parts is increased, the configuration becomes more complicated, and thus the production cost is also increased.

The present invention has been made to solve these problems, and its purpose is to quickly or easily rewind the tape during playback or recording, so that it is possible to quickly or easily It is possible to provide a self-inverting tape recorder capable of traveling and at the same time enabling a tape driving direction to be changed by manual operation.

Therefore, the present invention forms a fast-acting operation member and a rewinding operation member, and when the magnetic head and the pinch roller are in the operating position, the magnetic head and the pinch roller are retracted in the direction of the stop position by manual operation of any operation member. Form a restraining member that interlocks with both the actuation and the double acting of the attenuation operation member, and when the attenuation operation member is in the middle of movement, restrains the operation of the rotation detecting member with the restraining member and returns the attenuation operation member when the actuation or double acting again. It is configured to solve the restraint.

Sending quickly during reproducing or recording operation When the operation member is moved, the magnetic head and the pinch roller retreat, and the tape is sent quickly in the same direction.

Then, the magnetic head and the pinch roller return to the operating position by returning to the thrust of the operating member and return to the original playback or recording operation state.

When the winding operation member is moved back during the playback or recording operation, the magnetic head and the pinch roller retreat, and at the same time, the restraining member restrains the copper of the rotation detecting member during the movement of the winding operation member. As described above, the tape running direction switching mechanism is operated to switch the tenip driving direction, and the tape is sent at high speed in the opposite direction.

Then, the high speed member once again constrains the rotation detecting member's motion while the winding operation member is moving, and the tape running direction switching mechanism is operated again, and the tape running direction is changed to its original state, and the magnetic head and the pinch roller return to the operating position. To resume playback or recording operation.

If the winding operation member is moved back to an intermediate position during the playback or recording operation, the restraining member restrains the operation of the rotation detecting member to activate the tape traveling direction switching mechanism, and the playback or recording operation is performed while the tape running direction is switched. Continue.

1 is a plan view of a mechanical element of a cassette type tape recorder having an automatic reversing function, in which 1 is a main board.

On the upper surface side of the main board 1, a tape drive mechanism including a pair of rail shafts 2a and 2b, capstan shafts 3a and 3b, and a motor 4 for rotationally driving them is mounted.

The motor 4 simultaneously rotates both cap stand shafts 3a and 3b in the tape sending direction, and simultaneously rotates one box of real shafts 2a and 2b in the tape winding direction, respectively.

On the upper surface of the main board 1, a head substrate 1a (see FIG. 6) mounted with a magnetic head for recording and reproducing is mounted with a sliding material in the up and down direction in FIG. 1 (or FIG. 6). 6a and 6b are attached to the pinch rollers corresponding to each of the cap stand shafts 3a and 3b.

A cassette holder 7 is mounted on the upper surface of the main board 1. The cassette holder 7 is a rotating plate 8 which is rotated in an up and down direction (orthogonal to the surface) with the right edge as the axis in FIG. It consists of a cassette insert 9 which rotates in the vertical direction with the left edge of the axis as the axis.

In addition, the amount of rotation in the upward direction of the rotating plate 8 is regulated by the stopper 10 formed on the side wall of the main plate 1, where the rotating plate 8 and the cassette insert 9 are generally moved from the main plate 1 where the rotating plate 8 moves upward. Keep parallel.

The cassette insert 9 has a cassette inserting hole 11 on the left end side in FIG. 1, and the tape cassette 12 can be inserted through the cassette inserting hole 11.

Then, as the rotating plate 8 rotates downward while the tape cassette 12 is inserted into the cassette insert 9, the tape cassette 12 is loaded on the rail shafts 2a and 2b and the cap stand shafts 3a and 3b.

Here, the position where the rotation plate 8 rotates downward and the tape cassette 12 is mounted on the rail shafts 2a and 2b and the cap stand shafts 3a and 3b is called the "operation position" of the cassette holder 7, and the rotation plate 8 is moved upward. The position where the cassette inserting hole 11 is rotated to enable the cassette inserting of the tape cassette 12 is referred to as the “stop position” of the cassette holder 7.

When the cassette holder 7 moves from the “stop position” to the “operation position”, the head substrate 1a moves upward in FIG. 1 in conjunction with this, and the magnetic head 5 is inserted into the tape cassette 12 so that the magnetic It comes in contact with the tape.

When the magnetic head 5 is inserted into the tape cassette 12 in this manner, the pinch rollers on the same shaft as the rail shaft on the side driven by the motor cooperate with the operation of the head substrate 1a to accumulate on the capstan shaft on the same side.

For example, when the right rail shaft 2a is driven, the right pinch roller 6a contacts the right capstan shaft 3a. In this way, the magnetic tape is driven in the right direction (or left direction) to record and play. Will be

In Fig. 1, reference numeral 13 denotes a rewinding operation member which also functions as a ruler tape traveling direction switching operation member, and 14 denotes a fast forward operation member.

Both of the operation members 13 and 14 are polymerized with each other in the upper position of the magnetic head 5, and are disposed to move forward and backward in the left and right directions in the drawing.

Then, by turning the winding operation member 13 in the right direction in the drawing, the rotational force of the motor is transmitted as the high speed rotation to the right rail 2b.

On the upper surface of the rotating plate 8, a spring receiving member 15 is supported by the shaft 15a, one end of which is mounted as a rotating material, and an ejecting member 16 is mounted on the rotating plate 8 in the inserting direction of the tape cassette 12 (left and right direction in the drawing). It is equipped with sliding material.

The spring receiving member 15 has its rotational end generally positioned toward the ejecting member 16, and its rotational amount is regulated by an arc hole 17 provided in the pivoting plate 8.

And between the ejection member 16 and the one end of the spring receiving member 15, the ejection spring 18 which consists of a deployment spring is crossed.

The ejection member 16 has at one end (left end in the drawing) a contact portion 19 to abut the tape cassette 12 inserted into the cassette insert 9, and at the other end into a one-tailed hub hole of the tape cassette 12 inserted into the cassette insert 9 It has 20 engaging projections.

In addition, on the lower surface side of the rotating plate 8, a plate-shaped locking member 21 is mounted on the shaft 15a of the spring receiving member 15 as a rotating material.

The locking member 21 is provided with a contact piece 22 positioned on an operation line of the eject member 16, and an engaging portion 23 for displaying the cassette holder 7 at an operating position by locking on the side wall edge of the main board 1. Always tense in direction.

In the above configuration, the tape cassette 12 is first inserted into the cassette holder 7 in the cassette holder hole 7 in the longitudinal direction in a generally parallel state with the main board 1 in the reproduction or recording operation.

In this way, the tip of the tape cassette 12 presses against the contact portion 19 of the eject member 16, and as a result, the eject member 16 moves against the eject spring 18,

In addition, when the elastic deformation amount of the eject spring 18 gradually increases as the ejection member 16 moves, and exceeds the position where the elastic deformation amount becomes the maximum, the elastic force of the eject spring 18 acts to move the eject member 16 in the moving direction.

Therefore, the force for pressing the tape cassette 12 is unnecessary, and the tape cassette 12 is drawn into the cassette holder 7 by the elastic force of the eject spring 18, while the eject member 16 presses the contact piece 22 of the locking member 21.

The locking member 21 rotates in response to the pulling spring 24, the locking portion 23 moves away from the side plate-like edge of the main board 1, and the cassette holder 7 lowers to the operating position, and the tape cassette 12 in the cassette insert 9 is the rail shaft 2a, 2b. And the cap stand shafts 3a and 3b.

In this case, when the lower end position of the cassette holder 7 is reached, the head substrate 1a is moved in conjunction with this, the magnetic head 5 is in contact with the magnetic tape, and the pinch roller (for example, 6a) corresponds to the corresponding capstan. In contact with the axis 3a, the recording or reproducing operation is performed.

Next, the tape rewinding operation will be described. Figs. 2 and 7 and later show the configuration of the tape traveling direction switching mechanism and its peripheral portion, and reference numeral 31 in the drawing denotes a switching plate.

This switching plate 31 is arrange | positioned at the upper surface side of the said main board | substrate 1, and is slidable to the left-right direction in drawing by engaging with the guide hole 32 and the guide pin 33. As shown in FIG.

A plate-shaped restraining member 34 is disposed on the lower surface side of the switching plate 31, and the restraining member 34 is slidable in the up and down direction in the drawing by fitting the guide hole 35 and the guide pin 36. The three-membered shaping portion 34a protrudes, and the bending piece 13b (see FIG. 5) formed in a part of the copper member 13 is pressed against the inclined surface of the shaping portion 34a by pressing the rewinding member 13. Move upward in the figure.

Rotating arms 37a and 37b are connected to the left and right sides of the switching plate 31 by fitting the long hole 39 and the pin 40.

Each pivot arm 37a, 37b is a rotation material centering around the cap stand shafts 3a, 3b, and gears 41a, 41b are rotatably mounted to the arms 37a, 37b via the shafts 42a, 42b.

In Figs. 2 and 7 and the subsequent figures, the gears are marked by a simple simple circle on the pitch circle for the sake of simplicity, and the interlocking parts of the gears are indicated by a tab.

In each of the gears 41a and 41b, the eccentric caps 43a and 43b and the pressing pins 43aa and 43bb are integrally formed.

Each of the gears 41a and 41b is engaged with gears 44a and 44b which rotate integrally with the eccentric cap stan shafts 3a and 3b, and the rotational force of the motor 4 is transmitted through the gears 44a and 44b.

Reference numerals 45a and 45b are left and right cam followers, which are mounted on the main board 1 as a rotating material, and the extension pieces 46a and 46b formed at one end are welded to the main surfaces of the eccentric cams 43a and 43b.

Further, abutment pieces 47a and 47b are formed adjacent to each of the extension pieces 46a and 46b at one end of each cam follower 45a or 45b.

Moreover, the hydraulic pressure piece 48a, 48b protrudes in the vicinity of the rotation center of each reduction lever 45a, 45b.

On the other hand, rotation detection plates 49a and 49b are arranged coaxially with each of the reel shafts 3a and 3b, and the pressing pieces 50a and 50b and the stopper pieces 51a and 51b are respectively protruded adjacent to the outer circumference of the detection plates 49a and 49b, respectively. The pressing pieces 50a and 50b are in contact with the hydraulic pieces 48a and 48b in the rotational direction.

The amount of rotation in the counterclockwise direction of the left rotation detection plate 49a is limited by the stopper piece 51a contacting the stopper 51aa, and the amount of rotation in the clockwise direction of the right rotation detection plate 49b is limited by the stopper piece 51b contacting the stopper 51bb. It is intended to be.

The rails 2a and 2b are mounted on the main board 1 as shown in FIG. 3 (However, the mounting structures of the left and right rails 2a and 2b are the same, and only the rail shafts 2b on the right side are shown in FIG. 3). do).

As shown in FIG. 3, a fixed shaft 52 is installed in the main board 1, and a cylindrical body 53 is installed in the fixed shaft 52 as a rotating material, and a flange 54 is formed at the lower end of the cylindrical body 53, and this flange 54 On the upper surface side of the rail, the rear gear 55b (the rear rail shaft 2a has a rear gear 55a) and the hydraulic plate 56 are rotatably disposed on the outer circumference of the cylindrical body 53, and the rotation on the upper surface side of the hydraulic plate 56 is performed. The detection plate 49b is arrange | positioned with the rotating material.

Then, a part of the hydraulic plate 56 is joined to the lower end of the rail shaft 2b in the rotational direction, and the rear plate 56 and the rail shaft 2b are rotated integrally.

In addition, a friction plate 57a, 57b, 57c made of felt or the like is inserted between the flange 54 and the reel gear 55b, the reel gear 55b and the hydraulic plate 56, and the hydraulic plate 56 and the rotation detection plate 49b, respectively. Doing.

The coil springs 59 and 60 were inserted between the rail retaining plate 58 and the rotary detection plate 49b mounted on the outer periphery of the rail shaft 2b and the hydraulic detection plate 49b, and between the hydraulic plate 56 and the rail shaft 2b, respectively. Friction mechanism for rotation transmission is formed by 57a, 57b, flange 54, reel gear 55b, hydraulic plate 56, and detection friction mechanism is applied by spring 59, friction plate 57c, hydraulic plate 56, and rotation detection plate 49b. Consists of.

Therefore, when the rotational force of the motor 4 is transmitted to the rail gear 55b, the rotational force is transmitted to the rail shaft 2b through the rotation transmission friction mechanism.

While the rail shaft 2b is rotating, the pressing piece 50b formed on the rotation detecting plate 49b pushes the hydraulic piece 48b of the cam follower 45b.

When the rail shaft 2b receives an excessive load during the rotation of the motor 4, such as when the tape end is reached, slippage occurs on the upper and lower surfaces of the friction plates 57a and 57b, and the rail shaft 2b is forcibly stopped. The pressure on the vessel is lost.

On the lower surface side of the restraint member 34, as shown in FIG. 2, the temporary stopper plate 61 is rotatably installed about the axis 62 on the main plate, and the stopper plate 61a is formed on the stopper plate 61 at this time. When the member 34 is slid upward in the drawing, the projection 63 protruding from the lower surface side of the restraining member 34 is engaged with the supporting portion 61a to prohibit the restraining member 34 downward.

A bent portion 61b is formed on the temporary plate 61, and a triangular ridge portion 31a is formed on the switch plate 31. When the switch plate 31 slides in the left and right directions in the drawing, the triangular ridge portion 31a The inclined surface is in contact with the bent portion 61b to rotate the temporary sign plate 61 counterclockwise in the figure.

Next, the relationship between the head substrate 1a on which the magnetic head 5 is attached, the returning member 13, and the fast-forward operation member 14 will be described according to FIGS. 4 to 6, and the head substrate 1a is in a state where the tape cassette is loaded. In the upper forward position in Fig. 4, that is, the playback or recording operation position.

On the other hand, projections 71 and 91 of the same shape are formed in the overlapping positions on the side edge portions of the rewinding operation member 13 and the fast-forward operation member 14.

In addition, a part of the lock member 72 (see FIG. 5) is positioned in the middle of the movement of the projections 71 and 91. The lock member 72 engages the projections 71 or 91 and prohibits the return of the operation member 13 or 14.

Rewind and rewind the operating member 13 or fast-forward operation member 14. When operating, press a part of the operating member to a part of the rotating member 75 (refer to FIG. 4) supported on the main board 1. Rotate to the direction.

Therefore, the rotating member 75 presses the pin 76 placed on the head substrate 1a downward in the drawing to move the head substrate 1a downward in the drawing.

The lock member 72 is supported by the auxiliary member 73 through the pin 74 as shown in FIG.

The auxiliary member 73 holds the lock member 72 in the return direction by the spring 77.

When the rewinding operation member 13 is pressed, the bending piece 13b of the rewinding operation member (refer to FIGS. 5 and 2) 13 is brought into contact with the inclined surface of the angled rib portion 34a to advance the restraining member 34. .

Therefore, the rotation transfer mechanism for selectively transmitting the rotational force to the rail shaft 2a or 2b in the motor 4 is operated to return from the regeneration operation to the winding operation.

Reference numerals 82a and 82b denote rod springs mounted on the switching plate 31, and reference numerals 83 and 84 denote pressing pieces formed at the lower ends of the lock member 72 and the auxiliary member 73, respectively.

2 shows a state in which the magnetic tape is driven in the right direction and the regeneration operation is being performed. At this time, the activator plate 31 is moving in the right direction in the drawing, and the right gear 44b, 41b and the reel gear 55b are engaged with each other in order. 6b is pressed against the gap stand shaft 3b by the right pinch.

In addition, since the switching plate 31 is moving in the right direction, the left ignition arm 37a is rotated counterclockwise in the drawing about the cap stand shaft 3a.

As a result, the gear 41a is pinched away from the reel gear 55a and 6a is also returned to the pivotal arm 37a at a position away from the cap stand shaft 3a.

The right cam follower 45b receives the pressurization by the press piece 59b of the rotation detection plate 49b as the hydraulic piece 48b, and pushes the extension piece 46b to the outer periphery of the eccentric cam 43b. Repeats the reciprocating operation.

At this time, when the longest radial portion of the eccentric cam 43b is in contact with the extension piece 46b, the contact portion 47b is positioned on the rotational track of the pressing piece 43bb, but the pressing piece 43bb is contacted with the rotation of the eccentric cam 43b before contacting the contact portion 47b. Since the follower 45b rotates clockwise in the drawing, the press pin 43bb does not contact the contact piece 47b as long as the cam follower 45b is pressed by the rotation detection plate 49b.

In addition, the cam follower 45a on the left side does not receive a pressing force from the pressing piece 50a of the rotation detection plate 49a, and always rotates in the clockwise direction with the rod spring 82a attached to the switching plate 31.

Therefore, the cam follower 45a repeats the reciprocating motion every time the gear 41a rotates once the extension piece 46a is pushed outward of the eccentric cam 43a.

In this state of FIG. 2, when the high-speed rewinding operation member 13 is pressed and operated, as shown in FIG. Rhythmically

Therefore, of the engaging arm portions 85b and 85a which will protrude on both sides of the upper end of the restraining member 34, the right engaging arm portion 85b pushes the stopper piece 51b of the detection plate 49b to separate the pressing piece 50b from the hydraulic pressure piece 48b, and counterclockwise of the detection plate 49b. Prohibit turn to travel.

There, the cam follower 45b stays in the position as it rotates counterclockwise by pushing the extension piece 46b from the longest radius of the eccentric cam 43b.

In this state, when the gear 41b rotates again, the pressing pin 43bb contacts the tip of the contact piece 47b, and the turning pressure 37b rotates clockwise as shown in FIG.

On the other hand, the restraint member 34 is moved back and then the projection 63 is engaged to the engagement portion 61a of the temporary stopper 61. Even after the bent piece 13b of the operating member 13 passes through the convex portion 34a of the restraint member 34, the restraint member 34 immediately follows. It does not return.

Then, if the switch plate 31 slides to the left in the drawing due to the rotation of the pivotal rock 37b, the triangular shaped convex part 31a of the switch plate 31 is combined with the bent portion 61b of the temporary signboard 61 to halve the temporary signboard 61. By rotating in the direction, the restraining member 34 releases the gage by the temporary gage plate and returns to the original position as shown in FIG.

In addition, when the restraining member 34 moves, the protrusion 34b formed at the rear end of the restraining member 34 pushes the pressing piece 84 of the auxiliary member 73 (see FIG. 5) to the left in the drawing as shown in FIG.

Therefore, even if the temporary plate 61 rotates in the counterclockwise direction as shown in FIG. 8, the end portion 61b of the temporary plate member 61 does not contact the pressing piece 84, and of course, the rotational force of the temporary plate 61 is locked through the pressing piece 84. It also does not deliver to the 72 pressing piece 83.

Accordingly, no malfunction occurs in which the winding operation member 13 is released by releasing the temporary stopper plate 61 in accordance with the operation of the switching plate 31.

In the clockwise rotation of the pivotal arm 37b, the gear 41b is separated from the reel gear 81b. As a result, the left pivotal arm 37a rotates in the clockwise direction in the drawing and moves as shown in FIG. Engage 41a with the reel gear 81a. Accordingly, the rotational force of the motor 4 is transmitted to the real gear 81a through the gears 44a and 41a.

At this time, the pinch roller 6a is retracted, and the head substrate 1a is retracted in accordance with the movement of the winding operation member 13, falling off the cap stand shaft, and the tape is returned to the left direction.

At this time, the temporary billboard 61 is returned to its original position.

Next, when the tape returns to the desired position and returns to the original regeneration operation, it is necessary to press the fast forward operation member 14, i.e., during the reverse winding operation, the tape is returned as shown in FIG. 6 and the winding operation member 13 is pressed by the lock member 72. Although held in the position, when the quick forwarding operation is operated, the lock member 72 is pushed downward in FIG. 6 at the tip inclined portion of the recessed portion 91 of the member 14 to be retracted by the lock member 72. The holding of the winding operation member 13 is released.

Therefore, the winding-up member 13 is returned by the spring 13a, but in the middle, the bent piece 13b abuts the part 34a of the restraining member 34, and once the restraining member 34 is moved as shown in FIG.

As a result, the left engagement arm 85a of the restraining member 34 returns the stopper piece 51a of the left detection plate 49a to the counterclockwise direction.

Therefore, the cam follower 45a is pushed to the longest radial portion of the eccentric cam 43a and remains at the position rotated in the clockwise direction. Therefore, the pressing pin 43aa contacts the tip of the contact piece 47a, and the rotation arm 37a is rotated counterclockwise by the rotational force of the gear 41a. Rotate on.

As a result, the gear 41a moves away from the reel gear 81a and the switch plate 31 moves in the right direction.

Therefore, the rotational arm 37b of the right side rotates counterclockwise and engages the right gear 41b with the reel gear 55b as shown in FIG.

By returning, the winding operation member 13 returns to the original non-operation position so that the head substrate 1a is advanced, the magnetic head 5 and the pinch roller 6b return to the operation position, and are in the original regeneration operation state.

When the tape is rolled up to the end in the return winding operation state of FIG. 9, the rail axis 2a and the detection plate 49a stop.

Therefore, the force of the cam follower 45a is lost, the longest radius of the eccentric cam 43a contacts the extension of the cam follower 45a, the push pin 43aa abuts the tip of the contact 47a, and the pivot arm 37a counterclockwise. Rotate in the direction.

Therefore, the switching plate 31 moves in the right direction in the drawing to rotate the right pivot arm 37b counterclockwise, and engages the gear 41b with the reel gear 55b.

In addition, the temporary plate 61 rotates counterclockwise in response to the movement of the switching plate 31 to press the pressing piece 84 of the auxiliary member 73, and press the pressing piece 83 of the lock member 72 through the pressing piece 84 again.

Therefore, the lock member 72 rotates and returns to release the holding of the winding operation member 13. As the operation member 13 returns, the head substrate 1a moves forward and returns to the original regeneration operation state. Next, during the regeneration operation, the tape is quickly sent to the desired position, and when it is returned to the original regeneration operation, it is sent quickly. And pinch to retract 6b.

As a result, the state of the fast forwarding operation is brought, and the tape is rolled back to the desired position, and the winding operation member 13 is pushed and released by the lock member 72 of the fast forwarding operation member 14.

The above described the case where the fast forwarding operation is performed while the tape in the right direction runs and the regeneration operation is performed. However, the rewinding operation member 13 can be pressed again while the rewinding operation is performed in the left direction. In this case, push the quick operation member 14 to operate.

Also, the operation of rewinding and fast forwarding during the recording operation is the same as during the playback operation.

As described above, in the present invention, in the case where the magnetic tape is running in either of the left and right directions to play or record, the rollback operation may be performed by operating the winding operation member. Since the operation member can be sent quickly, it is not necessary to check the running direction of the tape, and it is designed to rewind the tape and change the direction by operating it manually by using an automatic reverse tape running direction switching mechanism. The configuration is extremely simple.
