[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording / reproducing apparatus, and more particularly to a magnetic recording / reproducing apparatus having a loading post for forming a predetermined tape path.

[0002]

2. Description of the Related Art A so-called DAT (Digital Audio Tape Recorder) is known as a magnetic recording / reproducing apparatus. This DAT pulls out a magnetic tape from a tape cassette mounted in the apparatus by driving a plurality of posts such as a loading post attached to a loading base and a guide arm and a pinch roller attached to a pinch roller arm. A tape path is formed to be in contact with the rotating cylinder over a predetermined range.

FIG. 8 shows the structure of a conventional loading post. The loading post 1 shown in the figure is called a P6 post because it is the sixth loading post from the upstream side with respect to the flow of the magnetic tape in the normal running state. The loading post 1 is integrated with a driving mechanism of the pinch roller 2 to simplify the structure.

The loading post 1 stands upright on a loading arm 4 mounted on a support shaft 3 implanted in a DAT chassis (not shown). Further, the pinch roller 2 is erected on a pinch roller arm 6 which is also supported by a support shaft 5 implanted in a chassis. The loading arm 4 and the pinch roller arm 6 are connected by a coil spring 7, and the two arms 4 and 6 are configured to move integrally.

The two arms 4 and 6 are driven by a cam plate 8 shown by a dashed line in the figure.
The cam plate 8 is driven in a direction indicated by arrows A1 and A2 by a mode motor (not shown). Specifically, an engaging pin 9 is implanted in the loading arm 4, and the engaging pin 9 is engaged with a cam groove 10 formed in the cam plate 8.

When the tape is loaded, the engaging pin 9 is displaced along the shape of the cam groove 10 by the cam plate 8 moving in the A1 direction, whereby the loading arm 4 is rotated at a predetermined timing. Accordingly, the pinch roller arm 6 connected by the coil spring 7
The pinch roller 2 is also rotated to a predetermined position where the pinch roller 2 contacts the capstan 11.

FIG. 9 shows the structure of a conventional loading post 1. As shown in the figure, a loading post 1 having a conventional structure includes a loading arm 4
And a shaft 13 fitted and fixed to the bush 12. Therefore, in the loading post 1 having the conventional structure, after the bush 12 and the shaft 13 are once attached to the loading arm 4, the shaft 1 is attached to the loading arm 4.
The tilt angle and direction of No. 3 could not be adjusted.

FIG. 8 shows a state in which tape loading is completed. In FIG. 8, reference numeral 14 denotes a magnetic tape, 15 denotes a guide member for guiding and holding the pinch roller arm 6, and 16 and 17 denote loading bases. Shown is another post (not shown).

[0009]

In recent years, magnetic tapes have been made thinner to increase the recording time. By making the magnetic tape thinner, the amount of magnetic tape that can be wound around the tape cassette increases, enabling long-term recording and reproduction
However, it is known that the rigidity of the magnetic tape is reduced by reducing the thickness of the magnetic tape.

Further, the running speed of the magnetic tape is also improved. By increasing the running speed of the tape, it is possible to increase the speed of the search and improve the recording density.

However, as the magnetic tape becomes thinner and the tape running speed increases, the accuracy of the loading post greatly affects the stability of the tape running. That is, when the magnetic tape is thinned and the tape rigidity is reduced,
The magnetic tape runs while being guided exactly by the inclination and direction of the loading post. In addition, as the tape running speed increases, the tape running position is greatly deviated from the predetermined running position even if the tilt angle and the tilt direction of the loading post slightly shift.

Attention is again paid to the conventional loading post 1 shown in FIG. 8, and the conventional loading post 1 has a configuration in which the loading post 1 is simply erected on the loading arm 4 and the loading In this state (ie, the state shown in FIG. 8), the loading post 1 is configured to be supported only by the loading arm 4.

For this reason, if the inclination angle or the inclination direction of the loading post 1 is displaced due to an assembling error or the like, the tape traveling position is largely displaced from the predetermined traveling position as described above. There was a problem that magnetic recording and reproduction could not be performed.

In the configuration shown in FIG. 8, since the loading arm 4 and the pinch roller arm 6 are connected by the coil spring 7, when the pinch roller 2 is pressed against the capstan 11, this coil spring 7, a pulling force acts on the loading arm 4, which may cause a deviation in the inclination angle and the inclination direction of the loading post 1.

[0015] The present invention has been made in view of the above points, and has as its object to provide a magnetic recording / reproducing apparatus capable of accurately positioning a loading post.

[0016]

In order to solve the above-mentioned problems, in the present invention, a magnetic tape is pulled out of a tape cassette in accordance with the rotation of the loading arm. A loading post for forming a path, the loading post comprising a shaft fixed to a loading arm, and a tape guide mounted in a displaceable configuration with respect to the shaft; A magnetic recording / reproducing apparatus provided with a stopper for positioning the inclination angle and the inclination direction of the tape guide at a predetermined angle and direction by contacting the loading post at the predetermined loading position.
And the stopper is configured to be displaceable,
An elastic member that elastically biases the stopper toward the loading post is provided , and is brought into contact with the stopper.
Mechanism for fine adjustment of the angle and direction of the tape guide
Is provided.

[0017]

[0018]

With the above arrangement, the tape guide fixed to the loading arm and displaceable with respect to the shaft is positioned at a predetermined angle and direction by contacting the stopper with the stopper. Is done.

Therefore, even if the loading post is displaced in the inclination angle or the inclination direction due to an assembling error or the like, these errors are corrected by the tape guide coming into contact with the stopper and displacing, so that the proper inclination angle and Positioned in the tilt direction.

Since the stopper is configured to be displaceable and is elastically urged toward the loading post by an elastic member, it is possible to prevent a clearance from being generated between the stopper and the tape guide. Can,
The positioning of the tape guide can be performed more accurately.

Further, since the stopper is provided with an adjusting mechanism for finely adjusting the angle and direction of the tape guide, the tilt angle and the tilt direction of the tape guide can be finely adjusted while the apparatus is assembled. It can absorb the formation error and assembly error of each part,
Positioning can be performed accurately .

The schematic configuration of the device will be described.

The cassette loading / unloading mechanism is for loading a tape cassette (not shown) at a predetermined recording / reproducing processing position in the apparatus 20. The tape loading / unloading mechanism moves the cassette holder 25 into which the tape cassette is inserted. The cassette is mounted and unloaded. The cassette holder 25 is configured to move in the directions of arrows A1 and A2 in the figure via a mode cam mechanism 27, a driving lever 28, a link 29, and the like by a driving force of a mode motor 26. At the time of loading, the cassette holder 25 moves in the A2 direction, and at the time of ejection, the cassette holder 25 moves in the A1 direction.

The reel stand device is a mechanism for rotating and driving the supply-side reel device and the take-up reel device. In this embodiment, the supply-side reel device and the take-up reel device are each constituted by a reel motor. The so-called direct drive system is adopted. For this reason, the configuration of the reel base device is extremely simple. In addition, each reel device has a mode of the device 20 (for example, a recording / playback mode,
The rotation speed, the rotation direction, and the like are controlled by a fast-forward / rewind mode, a search mode, and the like.

The rotary cylinder 23 is mounted on a drum base 30 formed of a hard resin. The rotary cylinder 23 has a diameter of about 30 mm, and the magnetic tape is wound around the rotary cylinder 23 at a predetermined angle. The rotary cylinder 23 has substantially the same diameter as the diameter of the drum motor that drives the rotary cylinder 23. Therefore, the rotary cylinder 23 has a compact structure by being disposed coaxially with the upper part of the motor. The rotary cylinder 23 is provided with magnetic heads at intervals of, for example, 90 °. The magnetic head scans a magnetic tape to perform magnetic recording and reproduction.

The tape loading mechanism 24 pulls out the magnetic tape from the tape cassette, and
3 is a mechanism for winding around a predetermined angle. The tape loading mechanism 24 employs a so-called M-loading mechanism. A pair of loading bases 31 and 32 are moved along guide grooves 33 and 34 formed in the chassis 21 by a link mechanism (not shown). The tape is loaded or ejected. On the pair of loading bases 31, 32, loading posts 35, 36 and inclined poles 3 are provided.
7, 38 are erected.

Reference numeral 39 denotes a pinch roller disposed on the pinch roller arm 40. The pinch roller 39 moves by the rotation of the pinch roller arm 40 accompanying the tape loading operation and comes into contact with the capstan 41. The magnetic tape runs at a predetermined tape running speed by running while being sandwiched between the capstan 41 and the pinch roller 39. Further, the chassis 21 has a plurality of loading posts 42 to 4 for magnetic tape to form a predetermined tape.
5 and a tension arm 47 on which a tension pole 46 is provided to detect the tape tension of the magnetic tape.

The apparatus 10 is configured such that most of the components of the above-described reel base device and the tape loading mechanism 24 are disposed in a sub-chassis 48 which moves up and down with respect to the chassis 21. The sub-chassis 48 is configured to move upward during a loading operation and move downward during an ejection. As described above, the reel base unit and the tape loading mechanism 24 are disposed in the sub-chassis 48, and the sub-chassis 48 is moved up and down in accordance with the loading / ejecting operation, whereby the thickness of the apparatus 10 can be reduced.

In the apparatus 10 constructed as described above, the present invention is characterized by a loading post 45 constituting the tape loading mechanism 24. Since the loading post 45 is the sixth loading post from the upstream side in the running direction of the magnetic tape in the normal running state, it is called a P6 post. Hereinafter, the loading post 45 which is a feature of the present invention will be described in detail.

FIG. 1 is an enlarged view showing the loading post 45. As shown in FIG. The loading post 45 is integrated with a driving mechanism of the pinch roller 39 in order to simplify the structure similarly to the loading post 1 having the conventional configuration described with reference to FIG. The drawing shows the loading post 45 in a loading state (magnetic recording / reproducing state).

The loading post 45 stands on the loading arm 48. This loading arm 4
Reference numeral 8 is supported by a support shaft 49 implanted in the chassis 21, and is configured so that the loading post 48 moves as the loading arm 48 rotates. The pinch roller 39 is set up on a pinch roller arm 40 which is supported by a support shaft 50 implanted in the chassis 21.

The loading arm 48 and the pinch roller arm 40 are connected by a coil spring 51, and the two arms 40, 48 move integrally. The arms 40 and 48 are driven by a cam plate 52 shown by a dashed line in the figure.
The cam plate 52 is connected to the mode cam mechanism 27 driven by the mode motor 26.

The cam plate 52 is driven in the directions indicated by arrows B1 and B2 in the figure by the driving force of the mode motor 26 and at a predetermined timing controlled by the mode cam mechanism 27. Specifically, an engaging pin 53 is implanted in the loading arm 48, and the engaging pin 53 is engaged with a cam groove 54 formed in the cam plate 52.

Then, the engaging pin 53 is displaced along the shape of the cam groove 54 by the cam plate 52 which moves in the direction B1 during tape loading, whereby the loading arm 48 rotates about the support shaft 49 at a predetermined timing. Move. Accordingly, the pinch roller arm 40 connected by the coil spring 51 also rotates, and the pinch roller 3
9 contacts the capstan 41.

With the pinch roller 39 in contact with the capstan 41, the magnetic tape 55 pulled out of the tape cassette is in a state of being interposed between the pinch roller 39 and the capstan 41. Since the capstan 41 maintains a constant rotation speed, the pinch roller 39
And the magnetic tape 55 held between the capstans 41 runs at a constant speed.

Here, the structure of the loading post 45 is shown in FIG. As shown in FIG.
Reference numeral 5 denotes a shaft 56 fixed to the loading arm 48 in an upright state, and a tape guide 57 attached to the shaft 56. At a position near the tip of the shaft 56, a cap 59 having a recess 58 formed in the center is provided.

The tape guide 57 is a cylindrical member, and has a projection 60 having a triangular cross section at the center of the inner circumference. The surface of the cylindrical portion 61 of the tape guide 57 is a mirror surface for improving the sliding property with the magnetic tape 55, and the upper and lower ends have flanges 62, which regulate the running position of the magnetic tape 55. 63 are formed.

A convex portion 60 formed on the tape guide 57 is inserted into a concave portion 58 formed on the shaft 56.
Is engaged, the tape guide 57 is moved to the shaft 56.
Attached to. Further, since the concave portion 58 and the convex portion 60 are engaged in a loose fit state within a range where the tape guide 57 does not come off from the shaft 56, the tape guide 57 is
Is displaceable in the direction indicated by arrow C in FIG.

Returning to FIG. 1, the description will be continued. In the figure, 62
Is a pinch roller arm holding member provided to support the pinch roller arm 40, and has a holding groove (not shown in the figure) for engaging with the pinch roller arm 40 to be loaded. When the pinch roller arm 40 enters and engages with the groove, the movement of the pinch roller arm 40 (that is, the pinch roller 39) in the vertical direction (vertical direction with respect to the paper surface) is regulated, and stable running of the magnetic tape 55 is ensured. You. The pinch roller arm holding member 62 is fixed to the chassis 21 by screws 63.

At a predetermined loading position where the above-mentioned loading post 45 is loaded, a stopper which is a main part of the present invention is provided. First, the stopper 64 as a premise of the present invention will be described with reference to FIG.

The stopper 64 is fixed to the chassis 21 by screws 63 together with the pinch roller arm holding member 62. The stopper 64 has a V-shaped groove 65 with which the tape guide 57 provided on the loading post 45 comes into contact. The V-shaped groove 65 regulates the position of the abutted tape guide 57. Therefore, the shape of the V-shaped groove 65 determines the inclination angle and the inclination direction of the tape guide 57 in a state where the tape guide 57 abuts. It is configured to be positioned in an angle and a predetermined direction.

On the other hand, as described above, the loading post 45 has the tape guide 57 with respect to the shaft 56 as shown in FIG.
Since the tape guide 57 is in contact with the V-shaped groove 65, the tape guide 57 is displaced along the shape of the V-shaped groove 65 because the tape guide 57 is in contact with the V-shaped groove 65. Therefore, since the tape guide 57 is regulated by the shape of the V-shaped groove 65, it is positioned at a predetermined angle and in a predetermined direction.

Therefore, even if the loading post 45 (specifically, the shaft 56) is displaced in the inclination angle or the inclination direction due to an assembling error or the like, these errors are corrected by the tape guide 57 in the V-shaped groove of the stopper 64. Since it is corrected by being displaced by contacting with 65, it is positioned at an appropriate tilt angle and tilt direction. Thereby, the magnetic tape 5
Even if the tape 5 becomes thinner and the tape running speed increases, stable tape running without fluctuation in running position can be realized, and good magnetic recording / reproducing characteristics can be maintained.

However, in the configuration in which the stopper 64 is fixed to the chassis 21 as described above, the loading arm 4
In the case where there is a forming error or mounting error in the tape 8, or in the case where there is a mounting error in the stopper 64, the positioning accuracy of the tape guide 57 may also be reduced. Specifically, when the loading arm 48 does not rotate to the predetermined position due to the various errors described above, or when the mounting position of the stopper 64 is deviated from the predetermined position, the V of the stopper 64 in the loading state.
It is conceivable that the character groove 65 and the tape guide 57 are still separated.

As described above, the loading post 45 is configured such that the tape guide 57 can be displaced with respect to the shaft 56. Therefore, if there is a clearance between the V-shaped groove 65 and the tape guide 57, the tape guide 57 is displaced. The magnetic tape 14 is displaced or vibrated due to the running of the magnetic tape 14, so that stable running of the tape cannot be realized. The present invention is characterized in that the stopper is configured to reliably contact the tape guide 57. Hereinafter, the structure of the stopper 70 which is a main part of the present invention will be described with reference to FIG.

The stopper 70 is rotatably attached to a shaft member 71 fixed to the chassis 21. A fixing screw (not shown in the figure) for fixing the pinch roller arm holding member 62 to the chassis 21 is formed at the lower portion of the shaft member 71, and the stopper 70 is rotatable at the upper portion as described above. A supporting shaft portion is formed. A torsion spring 72 (appearing in FIG. 1B) is provided at a lower position of the shaft member 71 where the stopper 70 is provided. One end of the torsion spring 72 is locked by a pinch roller arm holding member 62 fixed to the chassis 21, and the other end is locked by a stopper 70. The stopper 70 is constantly urged to rotate in the direction of arrow D2 in the figure by the elastic force of the torsion spring 72.

The stopper 70 has a V-shaped groove 73 formed therein. The V-shaped groove 73 has the same configuration as the V-shaped groove 65 provided on the stopper 64 described with reference to FIG.
The tape guide 57 is configured to position the tilt angle and the tilt direction at a predetermined angle and a predetermined direction in a state where the tape guide 7 is in contact with the tape guide 57.

The stopper 70 has a tape guide 57
Is provided with a fine adjustment mechanism 74 for finely adjusting the position of the tape guide 57 in a state in which the tape guide abuts on the V-shaped groove 73. this
The fine adjustment mechanism 74 includes a leaf spring member 75 and an adjustment screw 76.

The leaf spring member 75 has a structure in which a fixed portion 77 and a displacement portion 78 bent substantially at right angles to the fixed portion 77 are integrally formed.

The fixing portion 77 is provided with a stopper 7 using a screw 79.
Thus, the leaf spring member 75 is fixed to the stopper 70. When the leaf spring member 75 is fixed to the stopper 70, the displacement portion 78
And extends in the horizontal direction along a side surface 70 a facing the tape guide 57. That is, the displacement portion 78 is configured to contact the upper portion of the tape guide 57 in a state where the tape guide 57 contacts the stopper 70.

The adjusting screw 76 is screwed into a screw hole 80 formed in the stopper 70, and the tip of the adjusting screw 76 is configured to abut a position near the tip of the displacement portion 78. Therefore, by operating the adjusting screw 76 to adjust the degree of screwing thereof, the displacement portion 78 changes the separation distance from the side surface 70a. On the other hand, since the displacement portion 78 is in contact with the upper portion of the tape guide 57 in a state where the tape guide 57 is in contact with the stopper 70 as described above, by adjusting the degree of screwing of the adjusting screw 76, the displacement Tape guide 5
7 can be finely adjusted.

As described above, by providing the fine adjustment mechanism 74, the inclination and the direction of the tape guide 57 can be finely adjusted by the adjustment screw 76 in a state where the tape guide 57 is in contact with the stopper 70. Therefore, the apparatus 20 is assembled. Since the tilt angle and the tilt direction of the tape guide 57 can be finely adjusted in the state, it is possible to absorb the formation error and the assembly error of each part, and to perform the positioning of the tape guide 57 more accurately. Become.

The stopper 70 having the above configuration is configured to be rotatable with respect to the shaft member 71 as described above.
The torsion spring 72 is configured to be urged to rotate in the direction D2 in the drawing . In the ejected state, the stopper 70 comes into contact with the loading post 45 , whereby the rotation in the direction D2 is restricted. The position of the stopper 70 in the eject state is a position displaced in the D1 direction from the predetermined loading position of the loading post 45 (see FIGS. 2 and 3).

Therefore, when the loading post 45 moves in the direction D1 due to the rotation of the loading arm 48 during the loading operation, the loading post 45
Before reaching the predetermined loading position, the loading post 45 comes into contact with the stopper 70, and then the loading post 45
Is pressed, in other words, the loading post 45 moves to the predetermined loading position while maintaining the state of contact with the stopper 70.

With this configuration, no clearance is generated between the tape guide 57 and the V-shaped groove 73 of the stopper 70, and the tape guide 57 can be reliably positioned. Also, the tape guide 57
After the abutment with the V-shaped groove 73, the torsion spring 72 urges the stopper 70 to rotate toward the loading post 45, so that rattling does not occur between the tape guide 57 and the stopper 70. From this point, the running of the magnetic tape 55 can be stabilized.

In the above embodiment, the fine adjustment mechanism 74 is used.
Has been described with the leaf spring member 75 and the adjusting screw 76, but the configuration of the fine adjustment mechanism is not limited to this. For example, as shown in FIG.
2 is integrally formed with a displacement portion 84 which is configured to be displaceable with respect to the main body portion 83.
The position of the tape guide 57 may be adjusted by displacing the tape guide 4 according to the degree of screwing of the adjusting screw 76.
Further, as shown in FIG. 7, the stopper 85 is composed of a base portion 86 and a movable portion 87, and the movable portion 87 can be fixed at a fixed position with respect to the base portion 86 in directions indicated by arrows E1 and E2. It is also possible to use the tape guide 57
Can be adjusted.

In the above-described embodiment, in the structure of the loading post 45, the cap 59 is provided so that the tape guide 57 can be displaced with respect to the shaft 56.
Although the concave portion 58 is formed in the cylindrical portion 61 and the convex portion 60 is formed inside the cylindrical portion 61, the convex portion and the concave portion may be arranged in reverse with the cap 59 and the cylindrical portion 61. Further, another structure may be used as long as the tape guide 57 can be displaced with respect to the shaft 56.

In the above embodiment, the tape guide 5
The V-shaped grooves 6
5 and 73 are shown, the tape guide 57
If the tape guide 57 can be positioned at a predetermined tilt angle and tilt direction, the tape guide 57 may be positioned using a configuration other than the V-shaped groove.

Further, in the above-described embodiment, the DAT has been described as an example of the magnetic recording / reproducing apparatus. However, it is needless to say that the present invention can be applied to a magnetic recording / reproducing apparatus having another configuration such as a video tape recorder. .

[0062]

As described above, according to the present invention, the tape guide fixed to the loading arm and displaceable with respect to the shaft is brought into contact with the stopper so that the inclination angle and the inclination direction can be set to the predetermined angles. Even if the loading post is displaced in the inclination angle or the inclination direction due to an assembly error or the like, these errors are corrected by the tape guide contacting the stopper and displacing, and the proper Positioning is performed at the tilt angle and the tilt direction.

Since the stopper is configured to be displaceable and elastically urged toward the loading post by an elastic member, it is possible to prevent a clearance from being generated between the stopper and the tape guide. Can,
The positioning of the tape guide can be performed more accurately. Therefore, even if the magnetic tape becomes thinner and the tape traveling speed increases, stable tape traveling without fluctuation of the traveling position can be realized, and good magnetic recording / reproducing characteristics can be maintained.

Further, by providing the stopper with an adjusting mechanism for finely adjusting the angle and direction of the tape guide, the tilt angle and the tilt direction of the tape guide can be finely adjusted while the apparatus is assembled. It can absorb the formation error and assembly error of each part,
Positioning can be performed accurately .
