Abstract

PURPOSE:To prevent the effect on magazine moving operation even when a cartridge is jumped out of a magazine by constituting a part by a comparatively low friction part where the cartridge is jumped out of the magazine in a cartridge automatic exchange device and in contact therewith. CONSTITUTION:A low friction sheet 10 is provided to a cartridge jump correction member 11 constituted of a low friction member in a taper from a projection of a cartridge tunnel 9 toward a low friction sheet 10 and a part where the cartridge 1 in the magazine 2 is jumped out of the magazine 2 and in contact therewith possibly. If the cartridge 1 in the magazine 2 is jumped out of it due to an earthquake and in contact with the low friction sheet 10, even when the cartridge 1 is moved, a magazine moving mechanism 6 is prevented from being unmoved. If a cartridge 1b jumped out near the cartridge tunnel 9 from the magazine 2 is moved by the magazine mechanism 4, the cartridge is returned into the magazine 2 by the cartridge jumping correcting member 11 and does not contact the cartridge tunnel 9.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic cartridge exchange device, and more particularly to an automatic cartridge exchange device that prevents a cartridge nozzle from popping out from a cartridge magazine.

A magnetic tape device is a device that records information on a magnetic tape or reads information recorded on a magnetic tape based on instructions from a computer or the like. The magnetic tape wound on a reel is attached to a magnetic tape device and reciprocated between the two reels, during which it comes into contact with a magnetic head to read/read information.
A dent is made.

Recently, a magnetic tape and two reels have been made into a cartridge, and a plurality of cartridges 1 are stacked and stored in a cartridge magazine (referred to as a magazine) 2 as shown in Fig. 3, and as shown in Fig. 4. The cartridge is mounted on a stand 5 fixed to the magazine moving mechanism 4 of the automatic cartridge exchange device 3, pushed out by the cartridge push-out mechanism 6, loaded into the recording and reproducing device 7, and subjected to magnetic tape reading/old processing. When the process is finished, there is a device that returns the cartridge 1 to the magazine 2, takes out the next cartridge 1 from the magazine 2, and repeats the process automatically.

Note that the magazine transfer mechanism 4 moves the magazine 2 up and down in order to select the cartridge 1 within the magazine 2. Further, 8 is a cartridge loading/unloading mechanism which returns the cartridge 1 after reading/writing processing to the magazine 2.

In the recording and reproducing apparatus equipped with the automatic cartridge exchange device 3 as described above, the magazine 2 is moved up and down in order to select and take out the cartridge 1 in the magazine 2 when recording and reproducing. It is desired that the vertical movement of the magazine 2 in the automatic cartridge exchange device 3 be performed smoothly without stopping, and that the recording and reproducing device perform automatic recording and reproducing operations.

[Conventional technology]

Conventionally, an automatic cartridge exchange device 3 shown in FIG. 4 has a magazine 2 containing a large number of cartridges l as shown in FIG. 3 mounted on a stand 5 of a magazine moving mechanism 4, so that the magazine 2 can be moved up and down. Cartridge 1 in said magazine 2
The cartridge 1 is pushed out to the recording/reproducing device 7 by the magazine push-out mechanism 6, and the cartridge 1 is automatically replaced.

[Problem that the invention seeks to solve]

As described above, the magazine 2 is transferred to the cartridge automatic exchange device 3.
Cartridge 1 is loaded in magazine 2.
It is constructed so that it can be jumped out of. 10,000 - A protrusion (
There is a cartridge nozzle tunnel 9 at the entrance where the cartridge 1 comes in and out, or a screw head that fixes the automatic cartridge exchange device 3 and the recording/reproducing device 7), and when the magazine 2 is moved up and down by the automatic cartridge exchange device 3, There is a problem that the cartridge l may get caught on the protrusion and the magazine 2 may not be able to move.

In addition, since the A section was made of iron plate or the like and a material with relatively low friction was not used, a relatively large frictional force was generated when the magazine 2 tried to move while the cartridge 1 and the A section were in contact with each other. Since this occurs, there is a problem that the moving operation may not be possible in the same manner as described above.

[Means for solving problems]

The above problem can be solved by providing a low-friction member on the inner surface of the automatic cartridge exchange device near the entrance through which cartridges enter and exit, or by providing a low-friction member that pushes back the cartridges that have ejected from the cartridge magazine mounted in the automatic cartridge exchange device, or by removing the entrance from the automatic cartridge exchange device. This is achieved by the automatic cartridge/nozzle exchange device of the present invention provided on the inner surface of the cartridge.

[Effect]

In other words, by making part A, where a cartridge may come into contact with a magazine in an automatic cartridge exchange device, smooth and made of a relatively low-friction material, it is possible to automatically exchange cartridges that are thrown out due to earthquakes, etc. Even if the magazine moving mechanism moves due to contact with the inner surface of the device, a large frictional force will not be generated. Therefore, the magazine moving mechanism can be smoothly moved up and down.

〔Example〕

Hereinafter, the gist of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of the present invention.

Note that the same reference numerals throughout the figures indicate the same objects.

1, the difference from the conventional example shown in FIG. 4 is that a cartridge protrusion correcting member 11 made of a low-friction member is tapered from a protrusion of a cartridge tunnel 9 toward a low-friction seam O, which will be described later. A low-friction sheet 10 is provided at a portion where the cartridge 1 may jump out of the magazine 2 and come into contact with it.

The magazine 2 is mounted on the cartridge automatic exchange device 3,
Cartridge L in magazine 2 flies out due to an earthquake, etc. and comes into contact with low friction seam 0 (cartridge Ia shown)
), even if the cartridge l moves, it does not generate a large frictional force, so the magazine moving mechanism 6 does not become stuck.

Further, when the cartridge 1b protruding from the magazine 2 near the cartridge tunnel 9 is moved by the magazine moving mechanism 4, it is returned into the magazine 2 by the cartridge protrusion correcting member 11 and does not hit the cartridge tunnel 9. Therefore, as described above, the magazine moving mechanism 4 will not become stuck.

FIG. 2 shows another embodiment in which a low friction member 12 for preventing cartridge ejection is placed at a height equal to or higher than the protrusion of the cartridge tunnel 9 at a portion where the cartridge 1 may come into contact with the protrusion. It is set in.

Since the low friction member 12 for preventing cartridge popping out is formed in a flat shape, the frictional force generated between the cartridge 1 and the low friction member 120 for preventing cartridge popping out becomes smaller. Therefore, the effect is the same as described above, and the magazine moving mechanism 4 does not become stuck.

〔Effect of the invention〕

As explained above, according to the present invention, the parts of the automatic cartridge/nozzle exchange device where there is a possibility that the cartridges may come into contact with the magazines when they come out of the cartridges are made of relatively low-friction members. Therefore, it is possible to obtain a highly reliable automatic cartridge exchange device that does not affect the magazine movement operation.
