Description

[Detailed Description of the Invention] This invention relates to a rotating body control device for a magnetic recording/reproducing device.

2. Description of the Related Art A video tape recorder (hereinafter referred to as a VTR) can be loaded with a cassette tape to obtain functions such as recording and playing back the cassette tape.

In other words, insert the cassette into the cassette storage of the VTR,
When the cassette storage body is pressed into a predetermined position on the VTR main body, the cassette is associated with the reel shaft of the VTR.

In this case, the tape in the cassette is automatically pulled out from within the cassette by a loading disk and wrapped around the outer circumference of the rotating head, ready for the next operation.

In this way, VTRs use a rotating head for recording, so once the cassette is loaded in a predetermined position, the tape is pulled out of the cassette and wound around the rotating head to prepare for the next operation. Requires functionality for

This function is tentatively referred to as a preparation function here.

When operating the above preparation function, various automatic controls of the VTR are required.

First, ■ detecting that the cassette has been inserted and installed in the specified position, ■ then driving the loading disc to rotate, ■ loosening the brake on the reel stand, and ■ moving the loading disc to the specified position. Various control functions are required, such as stopping this rotational drive when the tape has spun, (2) and applying a brake to the reel stand at the same time as this stopping to apply tension so that the tape does not become loose.

Furthermore, during rapid feed or rewinding, it is necessary to control the reel stand so that no unnecessary moment of inertia remains.

With these restrictions, VTRs are required to have continuous tape forwarding and rewinding functions, but after performing this fast forwarding or rewinding, it is easy to immediately obtain the next function (playback or recording function). There is a need for a control device.

This idea was made in view of the above circumstances, and in particular, after the fast forwarding or rewinding function has been activated, it is possible to immediately return to the function that was set before the fast forwarding or rewinding. It is an object of the present invention to provide a rotating body control device for a magnetic recording/reproducing device that can obtain the following with a simple configuration.

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

FIG. 1 shows the inside of the VTR main body. A ring-shaped loading disk 11 is disposed on the chassis, and this loading disk is supported by guide rollers 12, 13, and 14 whose inner peripheral edges are supported by guide grooves. It is rotatably held.

Furthermore, a toothed surface is formed on the outer peripheral surface of the loading disk 11, and a gear 15 meshes with the toothed surface.

This gear 15 is rotationally driven by a motor 16 that is turned on during the preparation operation, and rotationally drives the loading disk 11 in the direction of arrow A in the figure.

Further, since the motor 16 is rotated in the reverse direction during injection, the loading disk 11 can also be rotated in the direction of arrow B in the figure.

Next, inside the loading disk 11, a rotary head 25 is arranged at an eccentric position of the disk.

Furthermore, inside the loading disk 11, a capstan 26, a magnetic head 27 for audio/control signals, a magnetic head 28 for erasing, a tension lever 29, a pole 30, etc. are also arranged.

On the other hand, a pair of reel stands 41 and 42 are arranged on the outer peripheral side of the loading disk 11.

Reel shaft 41' of this reel stand 41.42. 42' is used by fitting the reel shaft hole of the cassette 43.

Note that 45, 46, 47, and 48 are tape guides inside the cassette.

The above-mentioned FIG. 1 shows a state in which the cassette 43 is installed in a predetermined position and preparation is completed, but at the beginning of the preparation, the loading disk is in the position shown in FIG. 2, and the pinch roller 22, tape guide roller 19 , 20, tape tension pole 30, etc. are located in the tape pull-out section 44 of the cassette 43.

In this state, when the cassette 43 is pressed to a predetermined position, the switch of the motor 16 is turned on by the cassette 43, and the motor 16 rotates the loading disk 11 in the direction of arrow A in the figure through the gear 15. Rotate it to the position shown in Figure 1.

When the loading disk 11 rotates while pulling the tape 50 to a predetermined position, the motor 16 is stopped by a switch changeover means to be described later.

The loading disk 11 is arranged to be inclined with respect to the axis so that the left side in the figure is downward and the right side is upward. At the same time, the guide rollers and the like that rotate from the left side in the figure at the cassette position are set so that they do not get caught on the tape while the tape is being drawn out.

Further, when the preparation is completed and the recording or playback operation member is operated, the pinch roller 22 is pushed in the direction of the arrow shown in FIG. At the same time, the tape is inserted and tape feeding begins.

In this case, during the preparation period, the tension lever 29 is rotated by a cam or the like in the direction of arrow E, as shown in FIG. 1, and operates to elastically apply tension to the tape.

During the preparation operation described above, it is necessary to sequentially detect the operation process and cause the VTR to perform correct control operations.

Therefore, in this invention, a loading disk state detection member 60 as shown in FIG. 3 is used.

In FIG. 3, reference numeral 60 denotes a loading disk state detection member rotatably supported on the chassis by a fulcrum shaft M□. It extends in the direction of rotational angle and has an integral part.

The first friction member 71 is attached to the tip of an arm 73 having a relatively flexible elastic force, and the second friction member 72 is attached to the tip of a hard arm 74.

These arms are integrally formed of synthetic resin, but the arms 73 may be made of metal plate springs.

Further, this brake member 70 has the arms 73, 74
It also integrally includes a release arm 75 that extends in a rotational angle direction different from that of the other devices.

A long hole 76 is formed at the tip of the release arm 75 and is elongated in the tangential direction in which the arm rotates.

The loading disk state detection member 60 is rotatable in the direction of the arrow GOH shown in the figure, but the spring 66
A biasing force is applied in the direction of arrow H in the figure.

The brake member 70 is also rotatable in the direction of arrows I-J in the figure, but normally the brake member 70 is rotated in the direction of arrow 1 in the figure.
The biasing force is given by

One end of a wire-shaped connecting member 85 is secured to the elongated hole 76 with a sufficient margin for wobbling.

The other end of the connecting member 85 extends toward a plunger device 86 disposed on the chassis at the peripheral edge of the loading disk, and is attached to a pinch roller control member 87 of the plunger device 86 .

This pinch roller control member 87 is a plunger device 86
By moving the movable element, rotation control is performed in the direction of arrow R4+S shown in the figure about a fulcrum shaft M3 set on the chassis.

Next, in the brake member 70, for example, the arm 14 is provided with a locking piece 18, which can also be locked to a plate-shaped slide member P1 that is linked to the operation of a fast-forwarding operator and a rewinding operator. .

Next, a support member 90 is disposed between the reel stands 41 and 42 and is rotatable in the ++L direction in the direction of the illustrated arrow around a fulcrum shaft M4 set on the chassis.

A rapid feed idler 91 that is constantly rotated by a motor is attached to one end of the support member 90.

Further, the other end of this support member 90 extends toward the operation section side of the VTR.

Furthermore, between the peripheral surfaces of the rapid feed idler 91 and the reel stand 41, there is disposed an unwinding idler 92 that can press against or separate from both rotating bodies.

This rewinding idler 92 is indicated by the arrow 04+ in the figure.
It is rotatably attached to a slide support member 93 that is slidable in the P direction.

Further, this slide support member 93 is slid in conjunction with the rewind operator.

Next, a winding idler 95 for playing and recording is disposed close to the rotating peripheral surface of the reel stand 42.

This take-up idler 95 is constantly rotated by a motor and is attached to one end of the support member 94.

This support member 94 is rotatably controlled in the direction of arrow T++U shown in the figure around a fulcrum shaft M5 set on the chassis.
The other end is interlocked with a play operator or a recording operator.

Next, a take-up and brake idler 96 can be pressed against or separated from the rotating circular surface of the reel stand 41.

This winding and brake idler 96 is connected to the support member 9
The belt 1 is rotatably supported at one end of the belt 7.
00, it can be linked to the gear 15.

Further, the support member 97 is rotatable in the direction of arrow M++N shown in the figure around a fulcrum shaft M6 set on the chassis.

The other end of the support member 97 extends toward the operation section of the VTR, and is driven in the direction of arrow M in the figure during functional operations such as recording, playback, fast forwarding, and rewinding.

The other end of the support member 97 is tensioned by a spring 98, and is biased in the direction of arrow M in the figure.

Furthermore, a pin-shaped protrusion 99 is provided at the other end of the support member 97 so as to protrude from the upper surface.

A slide member P2 disposed so as to overlap the slide member P1 can also be locked to this pin 99.

The slide member P2 can also slide in the direction of the arrow (■) in conjunction with the loading disk state detection member 60.

That is, this slide member P2 is attached to the reel stand 41.
The pin 81 of the loading detection arm 79 extending from the fulcrum shaft M1 can be engaged with the pin 81 of the loading detection arm 79 through the lower part of the fulcrum shaft M1.

This loading detection arm 79 is rotatably supported by a fulcrum shaft M1, and is supported by a spring 8 in the direction of arrow G in the figure.
0 to the brake control arm 63.

The device generally operates as follows.

First, when the cassette is mounted at a predetermined position in the cassette mounting section as shown in FIG. 2, the motor 15 is turned on and drives the loading disk 11 to rotate in the direction of arrow A in the figure.

Accordingly, the roller 64 rides on the second circumferential surface 1b of the cam portion 111, so that the loading disk state detection member 60 rotates in the direction of arrow G in the figure and assumes the second rotation angle position.

In this case, the loading detection arm 79 is
direction, and the slide member P2 is slid by the pin 81 in the direction of the arrow V shown in the figure.

As a result, the support member 97 is rotated in the direction of the arrow N shown in the figure, so that the winding and braking of the reel stand 42 by the brake idler 96 are released.

On the other hand, on the reel stand 41 side, the brake control arm 63 of the loading disc state detection section 60 rotates the brake member 70 in the direction of arrow J in the figure against the spring '77.

In this case, the rotation angle range is such that the brake member 70 is
As shown in the figure, the first friction member 71 is set to be in pressure contact with the reel stand 41.

In this case, a load such as a counter is applied to the reel stand 42 side.

In such a braking state, a preparatory action is obtained and the tape is drawn out from the cassette, resulting in the drawn out state as shown in FIG.

In addition, in the case of the above preparation operation, the brake member 70 is rotated by the brake control arm 63, but the slide member P2 is provided with a locking portion P21, which engages with the pin 81 and rotates the brake member 70. It may be arranged to be in a state as shown in Fig. 4.

When the above preparatory operation progresses and the state as shown in FIG. 1 is reached and the tape is completely pulled out, the roller 64 of the loading disk state detection member 60 moves to the third circumferential surface 1C.
and reaches the third rotational angular position.

This state is as shown in FIG.

In this state, the loading disc state detection member 60
is in a state where it has rotated to the greatest degree in the direction of arrow H in the figure than before.

Therefore, the switch drive arm 62 of this member 60 can drive the switch 65, and the output signal of this switch 65 is used as a stop signal for the drive circuit of the motor 15.

On the other hand, since the brake control arm 63 no longer acts on the brake member 70, the brake member 70 rotates in the direction of the arrow {circle around (2)} in the figure due to the tension of the spring 77, and presses the second friction member 72 against the reel stand 41.

Further, since the slide member P2 is also returned by the spring, the support member 97 is rotated in the direction of arrow M in the figure, and the reel stand 4
Apply the brakes for 2.

The above operation completes the preparation operation, and the tape is
The arrangement will be as shown in the figure.

Further, at this time, a large load is applied to each of the reel stands 41 and 42, and the tension state of the tape is maintained well.

In this state, various functions of the VTR can be operated.

VTR functions include playback, recording, fast forward, rewind, eject, pause, etc., which can be obtained by operating operators corresponding to each function.

The state shown in FIG. 5 is similar to the state shown in FIG. 3, but the turning-on of the switch 65 and the rotational angular position of the loading disc detection member 60 are somewhat different.

Therefore, the operations and effects during operation will be explained with reference to FIG. 3, which shows each idler.

In this device, first, during the preparation operation, that is, when the roller 64 is in contact with the second circumferential surface 1b, the brake member 70 is in the state shown in FIG. The brake is in a half-brake state.

The brake member 70 is rotatably supported, and a flexible arm 73 as an auxiliary brake and a hard arm 7 constitute two types of brake friction means.
This is obtained by having 4 in one piece.

In particular, it is difficult to set the rotation stroke of the brake member 70 to bring the brake state to a half-brake state, but with this device, since the arm 73 is biased by elastic force, it is relatively easy to approach the desired load. It also has the advantage of expanding tolerances in the design and accuracy of parts such as these brake members.

The purpose of obtaining such a half-brake state is to rotate the supply reel stand 41 while applying tension to the tape while the tape is being drawn out.

If too large a load is applied to the supply reel stand 41, there will be no tape winding residue on the take-up reel stand when the cassette is first used, and accidents such as tape stretching, twisting, and cutting may occur.

Therefore, in this device, the load on the supply reel stand 41 side can be automatically adjusted.

The situation in which a half-brake state as shown in Fig. 4 is obtained is as follows.
It can also be obtained when the VTR is switched to rewind mode or fast forward mode.

In other words, this is the rewind eye when the rewind operator is operated.

The idler 92 is moved in the direction of the arrow O shown in the figure, and the idler 91
The rotation is transmitted to the reel stand 41, and the reel stand 41 rotates in the winding direction.

In this case, the slide member P1 may be set to drive the brake member 70 in conjunction with the rewind operator.

In addition, during fast feed, the fast feed idler 91 is rotated in the direction of the arrow shown in the figure by the fast feed operator, and the reel stand 42 is rotated by the fast feed operator.
Rotate.

In this case as well, it is preferable to set the slide member P1 to slide in the direction of the arrow V shown in the figure in conjunction with the rapid feed operator, and to drive the brake member 70 in the direction of the arrow J shown in the figure.

As mentioned above, the brake member 70 moves in the direction of the arrow J shown in the figure.
During the preparation operation, during fast forwarding, rewinding, etc., the state shown in FIG. 4 is reached.

Of course, in such a case, the idler 9 on the reel stand 42 side
6 releases the brake on the reel stand 42 by the slide member P2.

Furthermore, during the rotational movement of the brake member 70 as described above, the plunger device 86 is off.

Furthermore, the pinch roller control member 87 provided in association with the plunger device 86 does not need to rotate.

Therefore, the rotational stroke of the brake member 70 during preparatory operation, rapid feed, and rewinding is controlled by the elongated hole 7 provided in this member.
6 to prevent unnecessary movement of the connecting member 85.

Next, a case in which a pause operation is performed in this device will be described.

When the brake member 70 is in the state shown in FIG. 5, a brake control means for recording, reproducing, or pausing is obtained as follows.

That is, when a recording or playback operation is performed, the plunger device 86 is turned on in conjunction with each operation because it is necessary to feed the tape at a constant speed.

Therefore, the pinch roller control member 87
In order to press the supporting member in the direction of the arrow R shown in the figure, the pinch roller pinches the tape together with the capstan 26, thereby making it possible to feed the tape at a constant speed.

In this case, the pinch roller control member 87
The brake member 70 is rotated in the direction of arrow J in the figure.

In this case, the tension stroke by the connecting member 85 is set such that both the grinding members 71 and 72 of the brake member 70 are in a non-contact state with the reel stand 41.

This effectively utilizes the operation of the plunger device 86 for pinch roller control for brake control.

In this way, by effectively utilizing the action of the plunger device 86 for brake control, the reel stand 41 can be rotated smoothly, and the timing for releasing the brake can also be accurately obtained at the same time as the tape is fed at a constant speed. During recording and playback in which six tapes are fed at a constant speed, which is advantageous, the support member 94 of the take-up idler 95 is elastically rotated in the direction of arrow U in the figure by these operators, so that the idler 95 The rotational force is transmitted to the reel stand 42.

In this case, the recording and playback controls are slide member P1.
The support member 97 of the idler 96 is rotated in the direction of the arrow N by elastically sliding it with an appropriate stroke in the direction of the arrow (■) shown in the figure.

Therefore, the brake on the take-up reel stand 42 is also released.

Next, when a pause operation is performed during recording and playback as described above, in conjunction with this pause operation, the support member 94 of the idler 95 in the operated state is elastically pressed and rotated in the direction of the arrow T in the figure. The reel stand 42 stops its rotation.

Further, since the slide member P1 is also elastically slid in the direction of arrow W in the figure, a brake is applied to the idler 96 on the reel stand 42.

Further, the plunger device 86 is turned off by the pause operator.

As a result, the brake member 70 returns in the direction of the arrow 1 shown in the figure, and the friction member 74 serving as the main brake is pressed against the reel stand 41.

Therefore, the reel stand 41 is braked accurately and strongly in time.

Therefore, a pause can be obtained without losing tape tension.

As described above, for the reel stand 41, the operation of the plunger device 86 that controls the pinch roller is linked to the brake member 70 to obtain brake release during recording and playback, and main brake operation during pause. The configuration provides accurate brake control of the reel stand.

Next, from the state shown in FIG. 5 in which the preparation operation is completed in the above device, an eject operation is also possible.

When the eject operation is performed, the rotation of the motor 16 is switched in the direction opposite to that during the preparatory operation by a switch interlocked with this operator, so that the belt 100 is rotated in the direction indicated by the arrow
Rotate in the direction.

Then, the loading disk 11 is returned in the direction of arrow B in the figure.

In this case, the rotational force of the motor 16 provided for driving the loading disk 11 is also transmitted to the idler 96, thereby rotating the reel stand 42 in the winding direction.

At this time, the reel stand 42 is braked as shown in FIG.

Therefore, as shown in FIG. 1, the portion of the tape pulled out of the cassette 43 is wound up by the take-up reel stand 42.

As mentioned above, the idler 96 is used for multiple purposes: 1. Furthermore, the rotation and stopping of the motor 16 can be effectively utilized and realized with a simple configuration.

In other words, when the loading disk stops, the idler 9
6 is used as a brake, and the stopping load of this idler 96 is applied to the gear 15, so that a stable brake torque can be applied to any direction of rotation of the reel stand 42.

In addition, since tape winding ends with the idler 96 in pressure contact with the take-up reel stand 42, the reel stand does not rotate into an unnecessary window when the cassette is floated from the cassette mounting section, and the inside of the cassette is Do not allow the tape to sag.

Furthermore, depending on the selection of the center of the gear 15 and the fulcrum shaft M6 of the support member 97, the idler 96 may
00 can also be used as the pressing force of the idler 96 against the reel stand 42, and the spring 98 can also be weakened.

Next, the features of this invention, particularly the control mechanism of the reel stand 42 and the tension lever 29, will be explained with reference to FIG. 6, together with the operations of the fast forwarding and rewinding functions.

In FIG. 6, the tension lever 29 is connected to the fulcrum shaft MIO.
The tension lever engaging arm 29a is rotatably attached to the chassis by a lever, and this lever is provided with a tension lever engaging arm 29a that rotates together with the lever.

A first arm 121 of a tension lever control member 120, which is rotatably attached to the chassis by a fulcrum shaft M9, can engage with this arm 29a.

The tension lever control member 120 has second and third arms 122 and 123 that extend in different rotation angle directions from the first arm 121 and are integrally formed.

The second arm 123 and the tension lever 29
A spring 124 is stretched between the engagement arms 29a, and a biasing force is applied to the tension lever 29 in the direction of arrow E in the figure.

The tension lever 29 is driven to position the pole 30 at the position shown by the broken line in the figure before the play operation, that is, at the time when the preparation operation is completed as shown in FIG.

This is because the tension lever control member 120 is rotated by an appropriate rotational angle in the direction of arrow 2F in the drawing, for example, by a cam on the inner periphery of the loading disk.

Third arm 12 of the tension lever control member 120
3, the pin provided on this is the play operation interlocking member 12
Further, the first arm 126 of No. 5
driven in the direction.

The play operation interlocking member 125, which receives this drive as shown in FIG. 6, is rotatably attached to the chassis by a fulcrum shaft M5.

The above-mentioned support member 94 is also attached to this fulcrum shaft M5, and as described above, this support member 94 is provided with the take-up idler 95.

The play operation interlocking member 125 has its second arm 12
7 extends along the support member 94 so as to protrude toward the winding idler 5 side.

The tip of this second arm 127 and the support member 9
A spring 129 is stretched between a part of 4.
As a result, the idler of the support member 94 is biased in the direction of arrow U in the drawing.

Therefore, when a play operation is performed as shown in the figure, the idler 94 is pressed against the circumferential surface of the reel stand 42.

Of course, the third arm 128 of the play operation interlocking member 120 extends toward the operation section of the VTR.

Next, the support member 94 includes, in addition to a portion that supports the take-up idler 95, first, second, and third arms 94a, 94b* 94c extending in three different rotation angle directions.
It has integrally.

The first arm 94a is for fast feed operation detection, the second arm 94
b is used to detect the rewinding operation, and the third arm 94c is used to release the tension lever.

The operation part of the VTR has a fulcrum shaft M? , a fast-forwarding operation interlocking member 131 and a rewinding operation interlocking member 133, which are rotatably attached around M8, are provided in parallel.

A portion of each of these interlocking members 131, 133 extends toward the tip of the first arm 94a for detecting rapid feed and the second arm 94b for detecting rewinding, and is provided at the extending end thereof. The pins 132 and 134 can be engaged with each arm, respectively.

The fast forwarding operation interlocking member 131 and the rewinding operation interlocking member 133 are indicated by arrows 2A4+2B in the figure, respectively.

It is freely rotatable in the 2C4+2D direction.

When the fast-feeding operation interlocking member 131 is rotated in the direction of the arrow 2A in the figure, the support member of the take-up idler is rotated in the downward direction of the arrow in the figure, and the idler 95 and the reel stand 42 are separated.

Furthermore, when the rewinding operation interlocking member 133 is rotated in the direction of the arrow 2C in the figure, the idler 95 and the reel stand 42 are similarly separated.

Next, when the rewinding operation interlocking member 133 or the fast forwarding operation interlocking member 131 rotates and rotates the support member 94 in the downward direction of the arrow shown in the figure, the third arm 94c for releasing the tension lever also supports this support member 94. It rotates together with the member in the downward direction shown by the arrow.

A pin 137 of a tape tension correction member 135 is disposed on the rotational path of the tension lever release arm 94.

The tape tension correction member 135 is indicated by arrow 2 G+ in the figure.
It is placed on the chassis so as to be movable in the +2H direction, and one end is connected to the engagement arm 29a of the tension lever 29 via an intermediate member 136 in the form of a wire, for example.

Further, one end of a flexible tension correction brake member 138 made of, for example, leather is attached to the other end of the tape tension correction member 135.

This tape tension correction brake member 138 is arranged so as to wrap around the small diameter portion of the lower part of the supply side reel stand 41 at an appropriate rotation angle, and the other end is fixed to the chassis.

Therefore, when the tape being pushed and stretched by the tension pole 30 loosens in the state shown in FIG. The brake member 137 applies a load to the reel stand 41 and vice versa.

The above-described control mechanism shown in FIG. 6 allows fast forwarding and rewinding to be performed even when the VTR is in the play operation state, with the operator maintained in the operating state.

This is because the support member 94 of the take-up idler 95 is interlocked with the arm of the play operation interlocking member 125 by a spring 129 as an elastic body, and the support member 94 is connected to the arm 94 of the play operation interlocking member 125. a, 9
4b, etc., and the fast feed interlocking member 131, the rewinding interlocking member 133, etc. are configured to be engaged with these arms, respectively.

Further, the rotation of the support member 94 at this time is effectively utilized, and the pin 137 is used for releasing the tension lever.
can be engaged with.

As a result, when rewinding or fast forwarding is performed during a play operation, when the operator is released, the original play operation can be immediately resumed, which has the effect of simplifying the operation.

Moreover, this control function can be simply achieved by providing an arm on the support member, and furthermore, by integrating a control arm for loosening the tape tension, the internal structure of the VTR can be further simplified.

As explained above, this invention is particularly capable of returning to the function that was set before fast forwarding or rewinding immediately after the fast forwarding or rewinding function has been activated, and this can be achieved with a simple configuration. It is possible to provide a rotating body control device for a magnetic recording and reproducing device.
