Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / reproducing apparatus, and particularly to a recording / reproducing apparatus in which a tape-shaped recording medium is obliquely loaded around a drum having a rotating head, and the rotating head is brought into contact with the tape-shaped recording medium. Also, the present invention relates to a recording / reproducing apparatus that performs reproduction.

[0002]

2. Description of the Related Art A VTR (Vi) for recording a video signal
A helical scan type recording / reproducing device is used as a data recorder for performing data recording of a digital tape recorder or a digital tape recorder. In this type of recording / reproducing apparatus, a magnetic tape is obliquely wound around a rotary head drum, and recording / reproducing is performed by bringing the rotary head into contact with the surface of the magnetic tape. At this time, since the magnetic tape is wound obliquely, if the magnetic tape runs slowly, the head scans obliquely on the magnetic tape, thereby performing helical scan recording and / or reproduction. It is.

[0003]

In such a helical scan type recording / reproducing apparatus, a magnetic head provided on a rotary head scans a magnetic tape traveling slowly, so that the magnetic tape is obliquely scanned. If a recording track is to be formed by effectively utilizing substantially the entire surface of the magnetic tape in the width direction, the rotary head scans the magnetic tape diagonally from near the edge of the magnetic tape. That is, the vicinity of the end in the width direction of the winding start position of the magnetic tape with respect to the drum is the entry position of the magnetic head. Therefore, during tape loading, the magnetic head interferes with the edge of the magnetic tape to be loaded, thereby damaging the edge of the magnetic tape. In particular, such a tendency becomes remarkable when the thickness of the base film constituting the magnetic tape is reduced.

A rotary head drum device is composed of a rotary drum having a head and a fixed drum, and a guide step is spirally formed on the outer peripheral surface of the fixed drum. The vehicle runs while guiding the lower edge of the vehicle. Therefore, when the magnetic tape is unloaded, the edge portion of the magnetic tape is caught on the guide step, thereby damaging the magnetic tape.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has been made in order to prevent damage by a head during loading of a tape-shaped recording medium and damage by a guide step during unloading. It is an object to provide a playback device.

[0006]

According to one aspect of the present invention, a tape-shaped recording medium is obliquely loaded around a drum having a rotary head, and the rotary head is brought into contact with the tape-shaped recording medium to perform recording and / or recording. Alternatively, in a recording / reproducing apparatus adapted to perform reproduction, loading means for loading and unloading the tape-shaped recording medium onto and from the drum, and the tape-shaped recording medium when the loading means unloads or unloads the tape-shaped recording medium. And a shift means for shifting a medium in the axial direction of the drum.

Here, the shift means is arranged such that the position where the widthwise side end of the tape-shaped recording medium intersects with the head at the time of loading is higher than the winding surface of the tape-shaped recording medium with respect to the drum. The tape-shaped recording medium may be shifted so as to be on the upstream side in the rotation direction or to reduce the time during which the side end of the tape-shaped recording medium and the head intersect. In addition, the side end of the tape-shaped recording medium is regulated by a step formed on the outer peripheral surface of the drum, and the shift means moves the side end of the tape-shaped recording medium from the step at the time of unloading. The tape-shaped recording medium may be shifted so that the tape-shaped recording medium floats or is caught between the stepped portion and the tape-shaped recording medium. Further, the shift means is constituted by guide means arranged along the periphery of the drum, and when the height of the guide means is changed, the sliding plate provided with the tape pull-out member moves along the guide means. The tape pull-out member may be shifted in the height direction. The guide member may shift the tape pull-out member on the slide plate on the supply side. Further, the guide member may shift the tape pull-out member on the sliding plate on the winding side.

Another main invention of the present application is to load a tape-shaped recording medium obliquely around a drum having a rotary head and record and / or reproduce data by bringing the rotary head into contact with the tape-shaped recording medium. A recording / reproducing apparatus configured to perform the loading and unloading of the tape-shaped recording medium onto and from the drum; and loading or unloading the tape-shaped recording medium by the loading means when loading or unloading the tape-shaped recording medium. And a tilting means for tilting the drum with respect to the outer peripheral surface of the drum.

[0009] Here, the inclining means may incline the tape-shaped recording medium so that a side end of the tape-shaped recording medium intersecting with the head is separated from an outer peripheral surface of the drum during loading. Also, the side end of the tape-shaped recording medium is regulated by a step formed on the outer peripheral surface of the drum, and the tilting means moves the side end of the tape-shaped recording medium away from the step during unloading. The tape-shaped recording medium may be inclined as described above. Further, the inclination means is constituted by a guide member arranged along the periphery of the drum, and a sliding plate provided with a tape pull-out member by changing an inclination angle of the guide surface of the guide member in a direction perpendicular to the running direction. When moving along the guide means, the inclination of the tape pull-out member may be changed. The guide member may change the inclination of the tape pull-out member on the slide plate on the supply side. The guide member may change the inclination of the tape pull-out member on the take-up side slide plate.

A preferred embodiment of the present invention includes a mechanism for moving the tape recording medium up and down in the height direction of the drum when the tape recording medium is loaded on the drum. Here, the mechanism for vertically moving the tape-shaped recording medium may be configured to vertically move independently the loading means disposed on the supply side with respect to the drum and the loading means disposed on the winding side with respect to the drum. . The loading means can not only move up and down in the height direction of the drum, but also can be inclined with respect to the drum.

According to the above aspect, since the tape-shaped recording medium moves up and down during loading,
Intersection between the tape-shaped recording medium and the head that causes damage can be avoided or reduced. Alternatively, it is possible to prevent or reduce the tape-shaped recording medium from being caught from the guide step of the fixed drum during unloading. This makes it possible to reduce damage during loading or unloading of the tape-shaped recording medium and extend the life of the tape-shaped recording medium. Also, by adding a function of inclining the loading mechanism with respect to the drum, the posture of the tape-shaped recording medium is changed during the loading operation or the unloading operation, thereby preventing damage to the tape-shaped recording medium, particularly to the edge portion. By inclining in the direction of reduction, damage to the tape-shaped recording medium can be prevented or reduced. Accordingly, the thickness of the tape-shaped recording medium can be reduced, and the length of the tape-shaped recording medium stored in a cassette or a cartridge can be further increased.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment shown in the drawings. This embodiment relates to a data recorder embodying the present invention. As shown in FIGS. 1 and 2, the data recorder includes a one-reel type cartridge 10, and pulls out a magnetic tape 11 wound in the cartridge 10 and winds the magnetic tape 11 around the head drum device 12. , Rotating magnetic head 1
3 (see FIGS. 13 and 15) is brought into contact with the magnetic tape 11 to perform recording and / or reproduction. After this, the magnetic tape 11 is taken up by the take-up reel 14.
To be wound up.

The cartridge 10 has a casing that is substantially square when viewed from above, and has a holding portion 1 on a part of a wall portion 18 thereof.
9 is provided, and the leader block 20 is held in the holding section 19. The leader block 20 is fixed to a portion on the leading end side of the magnetic tape 11. Then, when such a cartridge 10 is mounted on the apparatus, the leader block 20 is pulled out by the tape drawing means, and the leader block 20 is fixed to the substantially central portion of the take-up reel 14. In order to enable the leader block 20 to be fixed to the take-up reel 14, a cut 15 is formed in a flange portion of the take-up reel 14.

As described above, the leader block 20 is pulled out of the holding portion 19 of the cartridge 10 and the take-up reel 1 is
4 is fixed to the center of the magnetic tape 11.
Are located on the head drum device 12 side with respect to the supply side sliding plate 35 and the winding side sliding plate 38. That is, when the magnetic tape 11 is pulled out, the head drum device 12 is located on one side of the magnetic tape 11 and a sliding plate 35 having a roll guide 36 and an inclined guide 37 at the opposite side; The slide plate 38 having the roll guide 39 and the inclined guide 40 is located. Such a positional relationship enables tape loading described later.

As shown in FIGS. 13 to 17, the head drum device 12 includes a rotating drum 23 and a fixed drum 2.
4 is provided. The magnetic head 13 is mounted on the outer peripheral surface of the rotating drum 23 and at the lower end thereof. As shown in FIGS. 1 and 18 to 20, a spiral guide step 25 is formed on the outer peripheral surface of the fixed drum 24.

Next, a loading mechanism for mounting the magnetic tape 11 on the outer peripheral side of the head drum device 12 will be described. A guide block 30 is arranged around the head drum device 12. The guide block 30 is a member integrally formed of a synthetic resin molded body as shown in FIGS.
1, 32 are formed. These guide grooves 31, 32
Constitute a supply-side guide rail 33 and a winding-side guide rail 34, respectively.

A supply side slide plate 35 is mounted on the guide block 30 so as to move along the supply side guide rail 33 of the guide block 30. Sliding plate 35
Has a roll guide 36 and an inclined guide 37 at its upper part. On the other hand, a take-up sliding plate 38 is arranged to slide on the guide rail 34 on the take-up side.
A roll guide 39 and an inclined guide 40 are provided on the slide plate 38. The guide rails 33, 3
Receiving members 41 and 42 are fixed to the ends of 4 respectively.

As shown in FIG. 1, when the magnetic tape 11 is pulled out and not mounted on the head drum device 12, the vicinity of the roll guide 36 and the inclined guide 37 on the sliding plate 35 is set. , An intermediate roll guide 43 and a pair of supply side guides 44 and 46 are disposed. These guides 44, 46 are supported on an intermediate lever 45. A roll guide 47 is provided near the intermediate roll guide 43 and is movably supported by a lever 48.

A take-up guide 51 is arranged close to the roll guide 39 and the inclined guide 40 on the take-up sliding plate 38, and is supported on a lever 52. A capstan 53 is arranged near the end of the guide rail 34 of the guide block 30 and near the receiving member 42. The magnetic tape 11 is pressed against the outer peripheral surface of the capstan 53 by a pinch roller 54 so that the magnetic tape 11 runs at a constant speed.

In the above configuration, when the cartridge 10 around which the magnetic tape 11 is wound as shown in FIG. 1 is mounted on the recording / reproducing apparatus, the leader block 20 is pulled out from the holding portion 19 of the cartridge 10. With
The leader block 20 is moved by moving means (not shown), and is fixed to the center of the take-up reel 14 through the cut 15 of the reel 14. Thus, the magnetic tape 11 is wound between the cartridge 10 and the take-up reel 14. At this time, a pair of sliding plates 35 and 38 are located on the side opposite to the head drum device 12 with respect to the magnetic tape 11.

Accordingly, when the sliding plates 35 and 38 are moved along the guide rails 33 and 34 of the guide block 30, respectively, the magnetic tape 11 is loaded. That is, when the sliding plate 35 is moved along the guide rail 33, the roll guide 36 and the inclined guide 37 on the sliding plate 35 move the magnetic tape on the outer peripheral surface of the head drum device 12 and the left side in FIG. Wrap around the part. On the other hand, when the sliding plate 38 is moved forward along the guide rail 34, the roll guide 39 and the inclined guide 40 provided on the sliding plate 38 hook the magnetic tape 11 and It is wound around the head drum device 12 on the winding side.

The magnetic tape 11 is wound around a head drum device 12 comprising a rotating drum 23 and a fixed drum 24, and a capstan 53 and a pinch roller 5 are provided.
4 and slowly travels at a speed equal to the surface speed of the capstan 53. At this time, the magnetic tape 11 is pulled out of the cartridge 10 and is gradually taken up by the take-up reel 14.

On the other hand, the rotating drum 23 constituting the head drum device 12 rotates at a high speed, and the magnetic head 13 provided on the rotating drum 23 scans the magnetic tape 11 obliquely. Helical scan recording and / or reproduction is performed along an oblique track formed above.

After the predetermined recording and / or reproduction is completed, the guide rails 33 of the guide block 30
The sliding plates 35, 38 move back along the direction 34 in the unloading direction, that is, from the position shown in FIG. 2 to the position shown in FIG. As a result, the magnetic tape 11 is returned to a position where the cartridge 10 and the take-up reel 14 are directly connected, and the loading of the magnetic tape 11 onto the head drum device 12 is released. In such a state, the above-described moving mechanism removes the leader block 20 from the central portion of the take-up reel 14, removes the leader block 20 from the take-up reel 14 by the cut 15, and is formed on the wall portion 18 of the cartridge 10. It is stored in the holding unit 19. Therefore, the cartridge 10 which has been subjected to the predetermined recording and / or reproduction can be removed from the apparatus.

In the guide block 30 shown in FIGS. 3 to 8, the guide rail 33 on the loading side is not at a fixed height but along the moving direction of the sliding plate 35 as shown in FIG. The height is changing. That is, in the configuration shown in FIG. 9, the guide rail 33 is lower at the intermediate position. Accordingly, when the sliding plate 35 moves along the guide rail 33, the sliding plate 35 having the roll guide 36 and the inclined guide 37 descends on the way and then rises again.

The shifting operation of the sliding plate 35 in the height direction during the loading is to prevent the magnetic tape 11 from intersecting with the rotary head 13 or to reduce the intersecting time. That is, as shown in FIG. 13 and FIG.
3 and the outer peripheral surface of the fixed drum 24 are obliquely wound. At this time, the magnetic head 13 provided on the lower end side of the rotating drum 23 and protruding above the outer peripheral surface thereof intersects with the lower edge portion of the magnetic tape 11.

This is for the following reason. In order to effectively use the entire surface of the magnetic tape 11 in the width direction to form an oblique track, the magnetic head 13 starts to contact the magnetic tape 11 near the edge of the magnetic tape 11 when loading is completed. In addition, the traveling path of the magnetic tape 11 is regulated by the head drum device 12, the roll guide 36, and the inclined guide 37. However, when the magnetic tape 11 is loaded, the positional relationship between the roll guide 36 and the inclined guide 37 with respect to the drum 12 changes, and accordingly, the traveling path of the magnetic tape 11 also changes. Due to this change in the traveling path, the edge of the magnetic head 13 and the edge of the magnetic tape 11 intersect at the position where the magnetic tape 11 starts winding around the rotating drum 23. And the magnetic head 13
May damage the edge portion of the magnetic tape 11.

Therefore, in this embodiment, the slide plate 35 on the supply side is lowered when the tape is particularly loaded, so that the roll guide 36 and the inclined guide 37 are lowered in the height direction of the head drum device 12, and Within the range of the winding angle of the tape 11, the magnetic head 1
3 is prevented from intermingling with the magnetic tape 11, or even if interlaced, the time is reduced. That is, the magnetic tape 11 intersects with the magnetic head 13 outside the range of the winding angle and at the upstream side in the rotation direction of the rotary head 23.

Outside the range of the winding angle, as shown in FIGS.
, The magnetic head 13 does not intersect with the edge of the magnetic tape 11. That is, the magnetic head 13 starts contact with the magnetic tape 11 on the center side in the width direction of the magnetic tape 11. This avoids a round-up phenomenon in which the edge of the magnetic tape 11 is damaged by the edge of the magnetic head 13. After this, since the sliding plate 35 rises again and returns to the normal height, the formation of the tracks on the magnetic tape 11 is not disturbed or disturbed.

Next, the guide rail 34 on the winding side of the guide block 30 will be described with reference to FIG. As shown in FIG. 10, the guide rail 34 on the winding side has an intermediate position that is higher with respect to the beginning and the end, so that the slide plate 38 having the roll guide 39 and the inclined guide 40 has The loading operation is performed so as to rise once in the middle and then descend. In addition, during unloading, it will rise once at the intermediate position.

The reason why the guide rail 34 on the winding side is raised at the intermediate position will be described with reference to FIGS. That is, the magnetic tape 11 runs on the outer peripheral surface of the head drum device 12 in a state where the lower edge portion is regulated by the oblique guide step 25 of the fixed drum 24. When the unloading operation is performed from the horizontal direction during the unloading, the lower edge portion of the magnetic tape 11 is hooked on the upper surface of the guide step 25 as shown by a chain line in FIG. The lower edge is damaged.

However, when the sliding plate 38 is raised by the guide rail 34 during the unloading, the lower edge portion of the magnetic tape 11 separates from the guide step 25 as shown in FIG. Move in the direction in which catching is reduced. Therefore, the lower edge portion of the magnetic tape 11 is not hooked on the guide step 25 or the hooking is reduced, thereby preventing or reducing damage to the edge portion of the magnetic tape 11.

FIG. 11 shows another embodiment. This embodiment shows a guide rail 33 on the supply side of the guide lock 30. Here, as shown in FIG. 11A, when the height of both sides of the guide groove 34 is changed, the sliding plate 35
Is inclined to one side with respect to the guide groove 31.
Therefore, the roll guide 36 and the inclined guide 37 on the sliding plate 35 are also inclined with respect to the head drum device 12.

FIG. 11A shows a state where the upper ends of the roll guide 36 and the inclined guide 37 are inclined away from the rotary drum 23. On the other hand, FIG. 11B shows that the upper ends of the roll guide 36 and the inclined guide 37 are
3 is tilted so as to be close to the upper surface of FIG. Such a roll guide 36 and an inclined guide 3
The adjustment of the inclination angle of 7 may be combined with the change in the height direction of the roll guide 36 and the inclination guide 37, or only the inclination may be adjusted.

For example, when the roll guide 36 and the tilt guide 37 are tilted as shown in FIG.
17, the cross section in the width direction of the magnetic tape 11 is inclined as shown in FIG. Therefore, from this, especially the lower edge portion of the magnetic tape 11 is separated from the head drum device 12. This means that the entering magnetic head 1
3 can be prevented or reduced at the edges of the magnetic tape 11. As a result, rounding up of the magnetic tape 11 by the magnetic head 13 can be prevented or reduced.

FIG. 12 shows a state in which the inclination of the guide rail 34 of the guide block 30, particularly on the winding side, is changed. That is, as shown in FIG. 12A, the upper ends of the roll guide 39 and the inclined guide 40 on the slide plate 38 are inclined to the head drum device 12 side. Alternatively, conversely, as shown in FIG. 12B, the upper ends of the roll guide 39 and the inclined guide 40 on the slide plate 38 are separated from the peripheral surface of the head drum device 12 by inclining the guide rail 34 with respect to the width direction. Lean on.

FIG. 19 shows, in particular, as shown in FIG. 12A, the roll guides 39 and 40 on the sliding plate 38 are inclined toward the head drum device 12 so that the magnetic tape 1
The lower end of 1 is separated from the outer peripheral surface of the fixed drum 24. At this time, the sliding plate 35 is simultaneously shifted in the height direction by the structure shown in FIG. 10, so that the lower edge portion of the magnetic tape 11 is lifted up from the guide step 25 of the fixed drum 24. This makes it possible to prevent or reduce damage to the magnetic tape 11 due to the guide step 25 during unloading of the magnetic tape 11.

As described above, the data recorder of the present embodiment is provided on both sides of the head drum device 12, and the sliding plates 35, 38 which move along the guide rails 33, 34 of the guide block 30 hold the magnetic tape 11 on the magnetic tape 11. The head drum device 12 is pulled out and mounted on the head drum device 12 as shown in FIG.

As shown in FIG. 9, the surface of the guide rail 33 on the supply side is provided with a gradient, and when the sliding plate 35 moves on the guide rail 33, the gradient of the surface of the guide rail 33 is increased. Then, the roll guide 36 and the inclined guide 37 on the sliding plate 35 move up and down. The magnetic tape 11 moves up and down at the time of loading along with these up and down movements. In particular, the magnetic tape 11 using the vertical movement
The magnetic head 13 and the magnetic tape 11 can be shifted to the outside of the winding angle of the magnetic tape 11 when the loading operation is performed while the magnetic head 13 is lowered, and the magnetic head 13 starts contact with the magnetic tape 11. The position to be moved shifts to the center side in the width direction of the magnetic tape 11. This prevents or reduces the rounding up of the magnetic tape 11 by the magnetic head 13.

The guide rail 34 on the winding side has a slope independent of the guide rail 33 on the supply side as shown in FIG. Is carried out by the sliding plate 38 on the winding side. Such movement can prevent or reduce interference with the guide step 25 of the fixed drum 24 during unloading of the magnetic tape 11, thereby preventing or reducing damage to the magnetic tape 11.

The change in the height direction of the guide rails 33 and 34 as described above can be replaced by a change in the angle as shown in FIGS. 11 and 12, or a change in the height and the change in the angle. Can be used in combination. Therefore, the sliding plates 35 and 38 can be moved independently and in different positions in the height direction or while changing the angle with respect to the head drum device 12.
