Description

The present invention relates to a sliding mechanism and a sliding method of a magnetic tape device for pulling out a magnetic tape in a magnetic tape cartridge and guiding it to a take-up reel.

As an external storage device such as a computer, a magnetic tape device in which a magnetic tape cartridge is loaded is used.
For example, in the tape loading device of the magnetic recording / reproducing device shown in Patent Document 1 related to the present application, a leader pin is connected to the end of a magnetic tape housed in a cartridge, and the leader pin is pulled out by a leading block and wound. By guiding the magnetic tape to the slot of the take-up reel, the magnetic tape is taken up by the take-up reel.
Then, the stored information of the magnetic tape pulled out from the magnetic tape cartridge via the reader pin is read by the magnetic head located in the middle of the moving path.

By the way, since a general leader pin has a size larger than the width of the magnetic tape, it is necessary to provide a notch so that the leader pin does not hit the upper and lower flanges of the take-up reel when the leader pin is pulled into the inside of the take-up reel. is there.
For example, the magnetic tape take-up reel shown in Patent Document 2 related to the present application has a structure in which a notch is provided in a part of the lower flange to avoid contact with a leader pin guided by a leading block. There is.

However, in the take-up reel shown in Patent Document 2, since a notch is provided in a part of the lower flange to avoid contact with the leader pin, the rigidity of the notch end portion becomes low and twisting or bending occurs. There is a problem that it is easy to do.
Then, in such a take-up reel, in order to prevent twisting and bending, for example, as shown in Patent Document 3 related to the present application, the space between the upper and lower flanges is widened to guide the winding of the magnetic tape. It is possible to avoid contact with the leader pin by attaching a protrusion only to the part to be used.
However, in a take-up reel having such protrusions, in order to improve the rotation balance, it is necessary to align the center of mass axis with the center of rotation axis and then increase or decrease the thickness of the flange depending on the location. , There is a problem that the flange processing is costly.

The present invention has been made in view of the above circumstances, and the leader pin connected to the end of the magnetic tape via the leader block is inserted into the slot of the take-up reel without providing a notch in the lower flange. To provide a sliding mechanism and a sliding method for a magnetic tape device, which can be guided to the above, thereby simplifying the flange structure and reducing the production cost.

In order to solve the above problems, the present invention proposes the following means.
The sliding mechanism of the magnetic tape device shown in the first aspect of the present invention grips the reader pin connected to the magnetic tape between the magnetic tape cartridge and the take-up reel by a reader block and moves it in the horizontal direction. The magnetic tape device has a moving mechanism for moving the leader block, and the moving mechanism moves the leader block to the take-up reel when the leader pin moves in an internal space along the radial direction of the take-up reel. It is characterized by being provided with a guide mechanism that moves relative to the lower flange so as to move away from the lower flange.

In the sliding method of the magnetic tape device shown in the second aspect of the present invention, the reader pin connected to the magnetic tape is gripped by the reader block and moved in the horizontal direction between the magnetic tape cartridge and the take-up reel. In the magnetic tape device, when the leader pin moves in the internal space along the radial direction of the take-up reel, the leader block is relatively moved in the vertical direction so as to be separated from the lower flange of the take-up reel. It is a feature.

According to the present invention, it is possible to simplify the flange structure of the sliding device and reduce the production cost.

The wound magnetic tape 1 is housed in the internal space 8 located between the flanges 7.

The moving mechanism 4 has a leader block 3 that grips the leader pin 2 connected to the magnetic tape 1 (see arrow a1) and guides the leader pin 2 to the hub 5 of the take-up reel R.
Further, the moving mechanism 4 draws the reader pin 2 to which the magnetic tape 1 is connected into the internal space 8 along the radial direction of the take-up reel R by the reader block 3, and when moving the internal space 8, the reader is used. A guide mechanism 9 for moving the block 3 relative to the lower flange 7 of the take-up reel R in the vertical direction is provided (see arrows a2 to a5).
In the sliding mechanism 100, the magnetic tape 1 pulled out from the magnetic tape cartridge C by the reader block 3 reads information by a magnetic head (not shown) provided on the way to the take-up reel R. Writing is done.

Then, according to the sliding mechanism 100 of the magnetic tape device configured as described above, the leader pin 2 crosses the internal space 8 along the radial direction of the take-up reel R by the guide mechanism 9 provided in the moving mechanism 4. The leader block 3 to which the leader pin 2 is gripped can be relatively moved in the vertical direction so as to be separated from the lower flange 7 of the take-up reel R.
As a result, in the threading mechanism 100, the leader block 3 and the leader pin 2 can be prevented from interfering with the lower flange 7 of the take-up reel R, and as a result, the lower flange 7 of the take-up reel R can be prevented from interfering with the lower flange 7. It is not necessary to provide a notch on the tape receiving surface 7A, and the flange structure can be simplified and the production cost can be reduced.

Next, the sliding mechanism 101 of the magnetic tape device according to the embodiment of the present invention will be described with reference to FIGS. 2 to 11.
As shown in FIGS. 2 and 3, the sliding mechanism 101 of the magnetic tape device is connected to the end of the magnetic tape 11 between the magnetic tape cartridge C1 loaded in the device main body 10 and the take-up reel R1. It has a moving mechanism 14 (described later) that grips the leader pin 12 by the leader block 13 and moves it in the horizontal direction (arrow A1 direction).

The magnetic tape cartridge C1 is a cassette in which the magnetic tape 11 is wound around an internal take-up reel (not shown), and is provided detachably with respect to the apparatus main body 10.
A leader pin 12 is connected to the end of the magnetic tape 11 housed in the magnetic tape cartridge C1, and the magnetic tape 11 is guided to the take-up reel R1 by pulling out the leader pin 12 by the reader block 13.

Further, as shown in FIG. 3, the magnetic head 20 and the magnetic tape 11 for reading and writing information are guided to the moving path of the magnetic tape 11 located between the magnetic tape cartridge C1 and the take-up reel R1. A tape guide 21 is provided.

Further, as shown in FIG. 4, the take-up reel R1 has an upper flange 16 and a lower flange 17 arranged at regular intervals in the vertical direction so as to be parallel to the hub 15 which is the center of rotation. It is a configuration.
The magnetic tape 11 guided by the leader pin 12 is wound around the internal space 18 located between the upper flange 16 and the lower flange 17.
The length M1 of the leader pin 12 is set to be larger than the width M2 of the magnetic tape 11 and the spacing M3 of the flanges 16 and 17 as shown in FIG. Therefore, it is necessary to control the movement of the leader pin 12 so that the leader pin 12 does not hit the flanges 16 and 17 of the take-up reel R1, which will be described later.

The moving mechanism 14 has a leader block 13 that grips the leader pin 12 connected to the magnetic tape 11 and guides it to the hub 15 of the take-up reel R1 as shown in FIGS. 2 and 3.
Further, the main body 14A of the moving mechanism 14 is provided with a sliding arm 31 having a drive shaft 31A driven by a drive motor (not shown).
In this sliding arm 31, a plurality of link members 31B and 31C are rotatably provided by a connecting shaft 31D (see FIG. 3), and the link member 31B on the proximal end side is connected to the drive shaft 31A and The leader block 13 is supported by the link member 31C on the tip side via the sliding pin 30.

As shown in FIG. 5, the leader block 13 is swingably provided along the axial direction (that is, the vertical direction B1) of the sliding pin 30, and is urged upward by the spring 13A.

Further, the main body 14A of the moving mechanism 14 is provided with a guide rail 33 and a guide protrusion 34 constituting the guide mechanism as shown in FIGS. 6 to 8.
The guide rail 33 serves as a path for guiding the leader block 13, and by contacting and sliding with the upper portion of the leader block 13 urged by the spring 13A, the leader block 13 is directed in a predetermined direction. I will guide you to.

Then, in the guide rail 33, the leader pin 12 to which the magnetic tape 11 is connected is drawn into the internal space 18 along the radial direction of the take-up reel R1 (that is, the horizontal direction along the arrow A1) and moves in the internal space 18. At this time, the leader block 13 has a flange slope 33A that moves the leader block 13 relative to the lower flange 17 of the take-up reel R1 in the vertical direction (direction of arrow B1) (see FIGS. 7, 8 and 10).
That is, the guide rail 33 is a detour route that relatively moves the leader block 13 in the vertical direction so as to be separated from the flange 17 on the lower side of the take-up reel R1.

The guide protrusion 34 is a flange-shaped protrusion provided on the guide rail 33 as shown in FIG. 9, and guides the leader block 13 guided to the hub 15 of the take-up reel R along the guide rail 33 to the leader pin 12 And push it down to insert it into the slot 40 formed in the hub 15.
As a result, the magnetic tape 11 drawn from the magnetic tape cartridge C1 is connected to the hub 15 of the take-up reel R1 and can be taken up by the take-up reel R1.

Further, in the sliding arm 31 of the moving mechanism 14, by reversing the drive motor, the leader pin 12 and the magnetic tape 11 connected to the leader pin 12 can be returned to the magnetic tape cartridge C1 through the guide rail 33.

The operation of the sliding mechanism 101 configured as described above will be described.
By driving the drive motor of the moving mechanism 14, the reader block 13 attached to the sliding pin 30 first comes into contact with the leader pin 12 in the magnetic tape cartridge C1 to grip the leader pin 12.
While the leader block 13 is operating to pick up the leader pin 12, the flange of the guide rail 33 suppresses the ascending operation of the leader block 13.

After that, the leader block 13 gripping the leader pin 12 moves to the take-up reel R1 side, and when it comes to the front of the take-up reel R1, rises along the flange slope 33A of the guide rail 33, and the take-up reel R1 It moves over the lower flange 17 (see FIG. 10).

After that, the leader block 13 that has moved on the lower flange 17 of the take-up reel R1 is lowered by the guide protrusion 34 (FIG. 9) located at the hub 15 of the take-up reel R1, and is lowered together with the leader pin 12 on the take-up reel. It fits in the slot 40 of R1.
In FIG. 19, the leader block 13 moves along the flange slope 33A of the guide rail 33, passes over the flange 17 on the lower side of the take-up reel R1, and is operated until it fits in the take-up reel R1. The locus is indicated by arrows A2 to A5.

Further, when the leader pin 12 is returned from the inside of the take-up reel R1 to the magnetic tape cartridge C1, the leader block 13 is similarly raised along the guide protrusion 34 of the take-up reel R1 to lower the take-up reel R1. Move on the flange 17.
At this time, after the leader block 13 has passed over the lower flange 17 of the take-up reel R1, it descends along the flange slope 33A of the guide rail 33, and the leader pin is inserted into the magnetic tape cartridge C1 at the height position. The operation of returning 12 is performed.

Then, according to the sliding mechanism 101 configured as described above, the leader pin 12 crosses the internal space 18 along the radial direction of the take-up reel R1 by the guide rail 33 constituting the guide mechanism in the moving mechanism 14. At this time, the leader block 13 to which the leader pin 12 is gripped can be relatively moved in the vertical direction so as to be separated from the lower flange 17 of the take-up reel R1.
As a result, in the sliding mechanism 101 of the present embodiment, the leader block 13 and the leader pin 12 can be prevented from interfering with the flange 17 on the lower side of the take-up reel R1.
As a result, in the sliding mechanism 101, as shown in FIG. 11, the tape receiving surface 17A of the lower flange 17 of the take-up reel R1 can be formed in a flat shape, and the flange structure can be simplified and the production cost can be reduced. Can be reduced.

More specifically, in the sliding mechanism 101 of the present embodiment, as shown in FIG. 12, it is not necessary to process a notch 50 on the tape receiving surface 17A of the flange 17 on the lower side of the take-up reel R1. As shown in FIG. 13, processing such as thickening the lower flange 17 to form a groove is not required.
As a result, in the present embodiment, as shown in FIG. 11, the tape receiving surface 17A of the lower flange 17 can be formed in a flat shape, and the flange structure can be simplified and the production cost can be reduced. Is.

That is, in the threading mechanism 101 of the present embodiment, the leader pin 12 is placed under the take-up reel R1 even if the lower flange 17 of the take-up reel R1 has a perfect disk shape without notches, grooves (steps) or protrusions. It can be pulled into the take-up reel R1 without interfering with the flange 17 on the side.
Further, in the sliding mechanism 101 of the present embodiment, since the take-up reel R1 can be resin-molded in a perfect disk shape, high rigidity and good moldability with less sink marks can be obtained.
Further, in the sliding mechanism 101 of the present embodiment, since the lower flange 17 of the take-up reel R1 has a perfect disk shape, the winding unevenness when the take-up reel R1 is rotated to take up the magnetic tape 11 is minimized. It is also possible to make it.
