CONSTITUTION:The cartridge transporting mechanism has cell blocks 2A and 2B fitted to the inner surfaces of two honeycombs 1 opposite to each other, a top casting 7 and an under casting 3 as upper and lower parts for connecting the two honeycombs 1 and the accessor 9 positioned between the top casting 7 and the under casting 3 and also between the cell blocks 2A and 2B. The mechanism has a top roller 4 and an under roller 5 for turning this accessor 9 and a top rail 6 and an X-rail 8, which are fixed to the top casting 7 and the under casting 3 respectively, for guiding these top roller 4 and under roller 5.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic tape device, and more particularly to a magnetic tape device having a cartridge carrying mechanism.

[0002]

2. Description of the Related Art As shown in FIG. 4, a cartridge carrying mechanism used in a conventional magnetic tape device has a base 20.
The honeycomb 11 having a hollow square tube structure fixed to the cell 11 and cell blocks 2A and 2B for accommodating a large number of cartridges fixed to both sides of the honeycomb 11 and the cell blocks 2A and 2B.
In the inner space between B, there is an accessor 9 that moves in the direction perpendicular to the paper surface. This accessor 9 is a cell block 2A, 2B
Is introduced to a predetermined position of, and a desired cartridge is taken into the accessor 9. Here, in order to move the accessor 9, a rectangular rod top rail 6 fixed to the upper portion of the honeycomb 11 and a round rod X rail 8 fixed to the lower portion of the honeycomb 11 (the X-axis in the direction perpendicular to the plane of the drawing) And a top roller 4 which is attached to the upper part of the accessor 9 with the rotating shaft 4A interposed therebetween and which rotates by using the top rail 6 as a guide. There was provided an under roller 5 having a concave surface that rotates using 8 as a guide.
Therefore, the accessor 9 has a structure in which the inner surfaces of the cell blocks 2A and 2B and the outer surfaces of the accessor 9 facing each other maintain a predetermined parallel gap. Top rails 6, X to hold the above-mentioned parallel gaps
The rail 5 was adjusted by finely moving the honeycomb 11, and the top roller 4 and the under roller 5 were finely adjusted so as to rotate smoothly with the rail.

[0003]

This conventional cartridge carrying mechanism is constructed by forming the honeycomb in a box shape, and increasing the accuracy in order to adjust the relative position of the rail and the roller with high accuracy, and minimizing the inclination. Since it has to be finished, it is expensive in terms of man-hours for installation and high-precision finishing. Further, since the top rail is a square bar, there is a drawback that it is not possible to absorb the component tolerance and the assembly variation of the X rails attached to the top rail and the lower portion.

The object of the present invention is to make a large contact between the inner surface of the cell block and the outer surface of the accessor while moving them with an appropriate gap so that the top rail, the X rail, the top roller, and the under roller rotate in contact with each other. An object of the present invention is to provide a cartridge carrying mechanism that can be adjusted with a simple structure without adjusting the honeycomb.

[0005]

SUMMARY OF THE INVENTION A magnetic tape device according to the present invention comprises a cell block portion for accommodating a plurality of magnetic tape cartridges, a honeycomb portion to which the cell block portion is attached, and an accessor for carrying the cartridge. And a rotating mechanism for moving the accessor section in parallel to two opposing surfaces of the cell block section, wherein the honeycomb section is composed of two parallel plates. And a top rail and an under rail that support the upper and lower sides of the above, and a top rail and an under rail that form a part of the rotation mechanism are attached to the top floor and the bottom rail, respectively. A top roller and an under roller that form a part are attached.

The present invention will be described below with reference to the drawings. 1 is a front view of an embodiment of the present invention, FIG. 2 is a cross-sectional view of FIG. 1, and FIG. 3 is a front view showing a state where a honeycomb of the present embodiment is inclined. 1, 2, and 3, the same reference numerals as those in FIG. 4 have the same configurations and functions. 1, FIG. 2, and FIG. 3, the upper and lower sides of the two opposing honeycombs 1 are supported by the under ridge 3 and the top ridge 7, and even when the honeycomb 1 is tilted, an X rail that can be attached to the under ridge 3 8 and the top rail 6 attached to the top object 1, the top roller 4 holding the top rail 6 from the left and right above the accessor and the accessor 9 are also moved.
An under roller 5 sandwiching the X rail 8 from below in the lower part of the table tilts the entire accessor 9 in accordance with the tilt of the honeycomb to keep the gap between the accessor 9 and the cell block 2 constant. The top rail 6 is a round bar,
Even when the honeycomb 1 is tilted, the structure is such that it makes a point contact with the top roller.

[0007]

As described above, according to the present invention, since the inclination of the accessor 9 is adapted to the inclination of the honeycomb, it has an effect of absorbing the vibration and the inclination of the honeycomb generated at the time of assembly. Cost can be reduced by making the honeycomb into two parts, that is, a box type, a top type, an under type and a honeycomb type. In addition, since the gap between the cell block and the accessor 9 can be reduced, it is also effective for downsizing the device.
