Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an automatic tape loading recording and/or reproducing device that performs recording and reproducing by pulling out a magnetic tape from a cassette using a loading member and loading it onto a tape path attached to a guide drum. .

BACKGROUND TECHNOLOGY In general, an automatic tape loading type VTR has a structure in which a base on which a loading pole is installed moves along a guide groove of a chassis, and the loading pole pulls out a magnetic tape from a cassette. A pair of circular protrusions, which are guided parts, are arranged on the lower surface of the base and are spaced apart in the direction of movement of the base.
The base moves by being guided by the guide groove on the front and rear circular protrusions. The loading pole moves along the center line of the guide groove. With conventional VTRs, there are no particular problems with the movement of the base and loading pole, but for example, as explained later, in connection with the enhancement of VTR functions, the audio control head protrudes into the loading pole movement path. However, when the chassis guide groove was bent significantly to accommodate this, the following problems occurred.

The loading pole base will move while being caught at the bent part of the guide groove.
The tape loading operation will not be performed smoothly.

The loading pole base moves by locking the pin on the lower surface to the radial slit in the ring that rotates during tape loading, but when the guide groove bends, the pin moves beyond the end of the slit. , it becomes impossible to perform a tape loading operation using a conventional loading ring.

Means for Solving the Problems Therefore, the present invention aims to provide an automatic tape loading recording and/or reproducing device that solves the above problems.
In the figure, a base 9 having a loading pole 10 erected on its upper surface moves guided portions 9a and 9b on its lower surface guided by a guide groove 12 of a chassis 7, and the loading pole 10 cassettes a magnetic tape 56. 2
In the apparatus 1 which performs recording and reproduction by pulling out the tape from the guide drum 5 and loading it onto a predetermined tape path 71 attached to the guide drum 5, a tape is inserted into the guide groove 12 in correspondence with the audio control head 35 disposed close to the guide groove 12. While forming a relief part 12a bent on one side,
A loading pole guide member 36 for guiding the loading pole is supported so as to elastically protrude into the guide groove 12 from a portion on the opposite side of the relief portion 12a, and The guided parts 9a and 9b are in the guide groove 1.
2 and when the base 9 passes the loading pole guide member 36, the loading pole 10 is moved around the guided parts 9a and 9b to move the loading pole 10 along the audio guide member 36. It is configured to move without colliding with the control head 35.

Function The loading pole guide member 36 guides the loading pole 10 on the upper surface of the base 9, and cooperates with the relief part 12a of the guide groove to direct the movement trajectory 80 of the loading pole 10 to the audio control head 75. It shall be bent to avoid collision.

The loading pole guide member 36 does not act on the guided parts 9a and 9b on the lower surface of the base, and
moves smoothly.

9 is a tape guide pole, and the arm 28
The pinch roller 26 is mounted on a bracket 30 that is integral with the pinch roller 26, and is located close to the pinch roller 26. The tape guide pole 29 has flanges 29a and 29b for guiding the upper and lower edges of the magnetic tape, and has the function of regulating the tape running height position. In addition, the bracket 30 is

The shape and center of rotation of the pinch roller support arm 28 are as shown in FIG. and the tape guide 59 of the cassette 2 so that it can come into contact with the magnetic tape from the outside.

In connection with the fact that the pressing position of the pinch roller 26 is biased to the left, the magnetic tape entering the tape clamping drive section consisting of the pinch roller 26 and the capstan 33 is not attached to the pinch roller 26 and is pushed to the clamping drive section. The tape guide pole 34 is installed in the positions shown in FIGS.
In addition, in order to ensure that the audio control head (A/C head) 35 is in contact with the magnetic tape, it is also offset to the left in the figure. That is, it is biased towards the guide drum 5 side and is disposed very close to the guide groove 12.

In connection with arranging the A/C head 35 in this way, the guide groove 12 has a wide shape with only one side bent at the A/C head 35 as shown in FIGS. 7A and B. The loading pole guide member 36 (hereinafter referred to as guide plate 36), which is a main part of the present invention, is provided. The guide plate 36 is supported by a shaft 37, is biased clockwise by a spring 38, and is locked to a stopper 39, and the guide portion 36a passes under the A/C head 35 to the above-mentioned escape point. It protrudes into the guide groove 12 on the opposite bank side of the portion 12a.

When the cassette is not installed, the drive ring assembly 1
9 and 18 are in the rotational positions shown in FIGS. 4A and 5A, respectively, and the loading pole mechanisms 13 and 8 are in the positions shown in FIG. 1, respectively. Tension arm 40 is rotating clockwise, and tension pole 41 is close to tilt pole 16. The left end of the slide plate 42 is locked to the sliding member 24 and slides to the left against the spring 43, and the arm 2
8 is rotated clockwise by a spring 44 until its locking arm 28a abuts the bent locking portion 42a at the right end of the slide plate 42, and the pinch roller 26 is further away from the capstan 33. Further, the main brakes 45, 46 and the loading tension brake 47 are in the on state as they are in contact with the corresponding reel discs 3, 4, respectively, and the sub brakes 48, 49 are in the off state as they are separated from the reel discs 3, 4. It is in. Further, the rotating arm 50 has a roller 51 at the tip thereof in contact with the outer circumferential surface of the sliding member 24, and is rotated counterclockwise about a shaft 52 by a spring (not shown).

In the above state, the cassette 2 is installed as shown in FIG. The vertical loading pole 15, the inclined pole 16, and the tension pole 41 are in the notch 2.
In a, the vertical loading pole 10 and the inclined pole 11 relatively enter into the notch 2b, and the capstan 33 relatively enters the notch 2c. When the attachment of the cassette 2 is detected by a micro switch (not shown), the brake solenoid 54 is energized, the main brakes 45 and 46 are turned off, and the loading motor (not shown) is started to close the drive ring. The assembly 18 rotates counterclockwise, the drive ring assembly 19 rotates clockwise, and the loading pawl mechanisms 8 and 13 move along the guide grooves 12 and 17, respectively, as shown by the arrows.
Start moving in the A ₁ and B ₁ directions.

When the drive ring assembly 18 rotates about 10 degrees, the protrusion 24b of the sliding member 24 toward the outer circumference pushes the roller 51, and the rotating arm 50 moves against the spring, as shown in FIG. It rotates clockwise, and this is detected by the sensor 55. When the sensor 55 detects the arm 50, the loading motor stops, and the loading pole mechanisms 8, 13 stop in a so-called half-loading state in which the magnetic tape 56 is partially pulled out from the cassette 2, as shown in the figure. The slide plate 42 moves to the right by the rotation of the drive ring assembly 18, and the arm 28 is pushed by the bending locking part 42a and rotates counterclockwise against the spring 44, and the pinch roller 26 is close to the capstan 33, and the tape guide pole 29 contacts the magnetic tape 56 from the outside of the tape path. In this state, the magnetic tape 56 is pulled out from the supply side tape winding body 57, guided by the tape guide 58 of the cassette 2, comes out of the cassette 2, guided by the vertical loading pole 15 and the inclined pole 16, and then guided by the tape guide 58 of the cassette 2. The capstan 33 and the pinch roller 26 are guided by an inclined pole 11 and a vertical guide pole 10 through a position remote from the drum 5.
A tape path 61 is formed in which the tape is guided by the tape guide pole 29 through between the tape guide 59 of the cassette 2, enters the cassette 2, and reaches the tape winding body 60 on the winding side. Ru.
After this, the brake solenoid 54 is turned off and the main brake is turned on.

In this state, fast forwarding and rewinding operations are performed. When performing fast forward operation, brake solenoid 5
4 is energized to turn off the main brakes 45 and 46, and the loading brake solenoid 53 is energized to turn off the loading tension brake 47.
is also turned off, the take-up reel motor is driven, the magnetic tape 56 is wound onto the take-up tape winding body 60, and the magnetic tape 56 runs at high speed in the forward direction along the tape path 61. The magnetic tape 56 is
Guided by a vertical loading pole 15 near the tape exit side of the cassette 2, guided by a vertical loading pole 10 at an approximately intermediate position, further guided by a tape guide pole 29 near the tape entrance side to the cassette 2, Fixed flanges 15b, 15c, 10b, 10c and flanges 29 at respective locations
The vehicle travels while being guided by the upper and lower edges by a and 29b and its travel height position is regulated. Therefore, the magnetic tape 56 runs along the tape path 61 without causing vibration in the tape width direction, and the tape winding body 60 on the winding side is in a state where the tape end surfaces are aligned in the same plane and there is no stepped winding. It is formed. Also, during rewinding operation,
The magnetic tape 56 is fed by running at high speed in the opposite direction without causing vibration in the tape width direction, with the tape running height position being regulated by the tape guide pole 29 and vertical loading poles 10 and 15 in the same way as in the above case. The side tape winding body 57 is formed without step winding.

Therefore, during the recording/reproduction mode and the reverse reproduction mode, which will be described later, the magnetic tape 58 remains at a constant height at the point where it is pulled out from the tape windings 57, 60.
Extracted from 0. Therefore, even at the exit point from the cassette 2, the magnetic tape 58 is pulled out of the cassette 2 without being displaced in the tape width direction, and the tape height position is kept constant. There will be no adverse effect on the tape, and there will be no damage to the side edges of the tape.

Note that during the above-mentioned fast forwarding and rewinding, since the rotating arm 50 is rotating clockwise as described above, the sub-brake arms 62 and 63 are released from the locking by the pin 64 on the rotating arm 50. Tebane 6
5, the sub brakes 48 and 49 press against the reel discs 3 and 4 by rotating clockwise and counterclockwise. As a result, reel discs 3 and 4
A braking force for applying tape back tension is applied to. Since the braking force for applying this back tension is applied mechanically, it is more stable than the electromagnetic brake of the reel motor.

If you perform a stop operation during fast forwarding or rewinding,
The reel motor stops and the brake solenoid 54
is turned off, and each reel disc 3, 4 is braked by the main brakes 45, 46. Also, the loading brake solenoid 53 is turned off,
A loading tension brake 47 brakes the reel disc 4.

When a recording or reproducing operation is performed in the above half-loading state, the brake solenoid 54 is energized, the main brakes 45 and 46 are turned off, the loading motor is started again, and the drive ring assemblies 18 and 19 are rotated counterclockwise, respectively. , rotates clockwise, and the loading pole mechanisms 8 and 13 pull out the magnetic tape 56 from the cassette 2 while the guide groove 1
2 and 17 in the direction of arrows A ₁ and B ₁ .
At this time, loading tension brake 47
is pressed against the reel disk 4 on the take-up side and turned on, and the magnetic tape 56 is pressed against the reel disk 4 on the take-up side.
7 and is pulled out from the cassette 2. The tension arm 40 once rotates to a position where it is stopped by the cancel lever 66, and then stops.
At the final stage of the loading operation, the cancel lever 66 is locked by the convex portion 23b on the ring 23 and rotated clockwise, thereby being released from the lock and rotating to the final position shown in FIG.
The operating transformer 67 that varies the rotational speed of the supply reel motor is operated. Also, the pinch roller solenoid 68 is energized, the arm 28 rotates counterclockwise, the pinch roller 26 is pressed against the capstan 33, and the tape guide pole 29 enters the notch 2c of the cassette 2.

The loading pole mechanisms 8 and 13 move to the final positions where they are pressed against the stoppers 69 and 70, respectively, and the magnetic tape 56 is placed on the circumferential surface of the guide drum 5 over a predetermined angular range as shown in FIG. The tape is loaded into a predetermined tape path 71 including an attached tape path. The magnetic tape 56 is guided by a tape guide 58 and pulled out of the cassette 2 from the supply tape roll 57, and is sequentially attached to the guide pin 72, tension pole 41, guide roller 73, full-width erasing head 74, and impedance roller 75. The guide drum 5 is in contact between the inclined poles 16 and 11.
Then, it is attached to the A/C head 35, the tape guide pole 34, and the pinch roller 26.
The tape guide 59 is clamped by the capstan 33 and attached to the tape guide pole 29.
The tape enters the cassette 2 and reaches the tape winding body 60 on the winding side.

When the tape loading operation is completed, the capstan 3
3 rotates in the normal direction, and the magnetic tape 56 is transferred to the pinch roller 26.
The tape is held and driven by the capstan 33 and runs along the tape path 71, and recording or reproduction is performed. When a reverse playback operation is performed, the capstan 33 is reversed, the magnetic tape 56 is pulled out from the tape winding body 60, runs in the reverse direction along the tape path 71, is wound around the tape winding body 57, and is played back in the reverse direction. will be carried out. Search again
When operating FF or search REW, capstan 3
3 rotates forward or reverse at a faster speed than normal, and the magnetic tape 56 is held and driven to run at about 10 times the normal speed to perform a forward search or a reverse search.

In each of the above modes, the magnetic tape 56 between the pinch roller 26 and the tape guide 59 runs while the tape running height position is regulated by the tape guide pole 29. For this reason, when the tape is running in the forward direction, the magnetic tape 5 is fed out from the pinch drive unit consisting of the pinch roller 26 and the capstan 33.
6, the tape running height position is regulated by the tape guide pole 29, and in this state, the tape guide 59
It enters into the cassette 2 guided by. Therefore, the tape travels within the tape path from the clamp drive unit to the take-up tape roll 60, and the take-up tape roll 60 is formed with the tape ends aligned on a flat surface. Ru. When the tape runs in the reverse direction,
The magnetic tape 56 is guided by a tape guide 59 and pulled out of the cassette 2.
The tape guide pole 2 is installed before reaching the clamping drive part.
9, the tape traveling height position is regulated, and in this state it enters the clamp drive section. Therefore,
The height of the tape running in the clamping drive unit remains constant without changing, and the tape running within the tape path on the downstream side of the clamping drive unit, that is, on the guide drum 5 side, becomes stable, and the reproduced image during reverse playback becomes stable. This prevents any adverse effects on the images, and allows good images to be reproduced even during reverse reproduction.

Here, the tape guide pole 29 described above moves together with the pinch roller arm 28, and a pinch roller contact/separation mechanism is used to move the tape guide pole 29 between the operating position and the non-operating position. There is no need to provide a dedicated mechanism, and the configuration is simple. In addition, since the tape guide pole 29 is not fitted into the notch 2c from the beginning, its diameter is not limited by the dimensions of the notch 2c and is made sufficiently large, so there is no concern about strength and reliability. becomes more sexual. Furthermore, the magnetic tape 56 is attached to the tape guide pole 29.
The attachment angle of the tape guide pole 29 is small, so the influence of the inclination of the tape guide pole 29 on the tape path is reduced, and assembly errors of the tape guide pole 29 are tolerated to a certain extent, which is also advantageous.

Also, since the location of the tape guide pole 34 has been changed, the magnetic tape 56 relative to the tape guide pole 34 has been changed.
The wrapping angle increases, and the tape running height regulating force at this portion also increases.

Further, in each of the above modes, the rotating arm 50 rotates counterclockwise, the sub brakes 48 and 49 are turned off, and the loading tension brake 47 is also turned off.

Furthermore, when the stop operation is performed during each of the above modes, the members related to the tape loading operation move in the opposite direction to the above, and the loading pole mechanisms 8 and 13 move in the directions of arrows A ₂ and B ₂ , respectively. After returning to the position shown in Figure 1, follow the arrows A ₁ ,
B The VTR ₁ moves a little in the 1 direction and then stops, and the VTR 1 is in the state shown in Fig. 2. If you perform the eject operation in this state, the loading pole mechanisms 8 and 13 will move to the first position.
Returning to the position shown in the figure, the cassette 2 is removed from the VTR 1.

Next, the operation of the loading pole mechanism 8, which is the essential part of the present invention, when it passes through a location facing the A/C head 35 will be explained with particular reference to FIGS. 7A and 7B.

As described above, the loading pole mechanism 8 moves in the direction of arrow _A1 with the hanging pin 9c being pushed by the side wall of the elongated hole 24a and the circular protrusions 9a and 9b being guided by the guide groove 12. When the vertical loading pole 10 located on the upper front side in the moving direction of the loading pole mechanism 8 is placed at a location facing the A/C head 35, the vertical loading pole 1
0 comes into contact with the guide portion 36a of the guide plate 36 protruding above the guide groove 12, and is guided thereby, the loading pole mechanism 8 moves the circular protrusion 9b side as shown in FIG. 7A. Rotating counterclockwise around the center, the vertical loading pole 10 moves to avoid the A/C head 35 without colliding with it. The above-mentioned rotation of the loading pole mechanism 8 is made possible because the circular protrusion 9a on the vertical loading pole 10 side enters into the relief portion 12a of the guide groove 12. When the vertical loading pole 10 passes the front side of the A/C head 35, the guidance of the vertical loading pole 10 by the guide portion 36a is released, and the circular protrusion 9a is guided by the relief portion 12a and moves into the guide groove 12.
Returning to the inside, the loading pole mechanism 8 rotates clockwise around the circular protrusion 9b.

The loading pole mechanism 8 moves without being guided by the guide part 36a other than the vertical loading pole 10, and the rear circular protrusion 9b is the seventh
As shown in FIG. B, it moves along the center of the guide groove 12 without entering the relief part 12a of the guide groove 12.

That is, the loading pole mechanism 8
6a, the vertical loading pole 10 moves along the guide portion 36a as shown by the solid line 80 in FIG. 8, and the rear circular protrusion 9b moves along the guide groove 12 as shown in FIG. It moves as shown by the middle broken line 81. Here, since the protrusion 9b moves along the guide groove 12 without being guided by the guide portion 36a, the movement range of the hanging pin 9c is limited to the sliding member 2.
4, and even if the radial displacement range of the drive ring assembly 18 of the vertical loading pole 10 exceeds the range of the elongated hole 24a, The drive ring assembly 18 described above can be used without problems.

During tape unloading, the vertical loading pole 10 is connected to the A/C head 35 in the same way as above.
Move to avoid.

Note that the guide plate 36 is not fixed by screws, but is rotated by a spring 38 and positioned in a state where it is stopped by a stopper 39. Therefore, even if the guide portion 36a protrudes excessively, the guide plate 36 is pushed by the loading pole 10 and is rotated counterclockwise against the spring 38, so that the guide portion 36a moves into the guide groove. By being partially pushed out of the loading pole 12, the loading pole 10 can move smoothly. That is,
The mounting position error of the guide plate 36 is designed so that it does not adversely affect the movement of the loading pole mechanism 8.

Effects As described above, according to the automatic tape loading recording and/or reproducing apparatus of the present invention, the loading pole guide member acts on the loading pole on the upper surface of the base, and does not act on the guided portion on the lower surface of the base. In order to avoid this problem, and because the guide groove relief part and the loading pole guide member are provided in the part corresponding to the audio control head,
It has the following features.

By making the guide groove a simple shape that allows the guided portion of the base to easily pass through, it is possible to transport the loading pole along, for example, a complicatedly curved trajectory.

The loading pole can be moved along a freely set trajectory using a conventional base moving mechanism without changing the shape of the guide groove, that is, without changing the design of the mechanism for moving the base.

Applicable to a device in which the audio control head is arranged close to the guide groove, the base moving mechanism remains the same as before, and the loading pole is prevented from colliding with the audio control head. It can be moved to .
