Abstract

PURPOSE:To effectively prevent the popping of a cartridge during conveyance by providing a shaft having a stepped notch at the entrance of a magazine and a leaf spring engaging therewith and controlling the deflection of the spring by the rotation of the shaft. CONSTITUTION:The shaft 8 having the stepped notches 9a, 9b at the entrance and exit of the magazine 12 and the leaf spring 10 having a roller 11 attached to the end thereof are provided. During conveyance the shaft 8 is energized downward by the spring 18, the leaf spring 10 contacts the periphery of the shaft 8 and the cartridge 2 is locked by the roller 11, so that during conveyance, the popping of the cartridge 2 can be prevented. When the magazine 12 is set to a device, the shaft 8 is raised by the protrusion 19 of the device main body and the leaf spring 10 engages with the notch 9b, so that the cartridge 2 can be easily unlocked. At the time of inserting the empty magazine, the shaft 8 is rotated by 180 deg. by a thumb 17.

Description

[Detailed Description of the Invention] [Summary] A magazine for use in a magnetic tape device, in which the magazine is provided with a shaft having notches at different levels and a leaf spring that engages with the notch, and the rotation of the shaft is controlled by the shaft. By regulating the deflection of the temporary spring by moving in the direction, the cartridge can be locked/
This allows the cartridges to be unlocked securely in the magazine, preventing them from falling out during transportation, and also making unlocking easier.

[Industrial application field]

The present invention relates to a cartridge magazine for storing cartridges in a magnetic tape device.

A cartridge magazine for storing cartridges in a magnetic tape device is transported with the cartridges inside. Therefore, it is necessary to lock the cartridge so that it does not fly out of the magazine during transportation. Further, when set in the device, the lock needs to be automatically released so that the cartridge can be freely taken in and out.

Also, when inserting a cartridge into an empty magazine, it is necessary to lock/unlock it. Therefore, there is a need for a cartridge magazine that can be automatically locked/frozen.

[Conventional technology]

Figures 3 (a) to (c) are diagrams explaining a conventional cartridge magazine, in which (a) is a perspective view, (b) is a locked state,
(c) indicates the unlocked state.

In the figure, cartridge magazine (hereinafter referred to as magazine) 1
As shown in FIG. 3(A), a storage shelf 3 for storing a plurality of cartridges 2 is provided, and a lid 5 having a protrusion 4 at the entrance/exit of the cartridges is provided. The lid 5 always has a spring 6
The cartridge 2, which is pulled downward by the projection 4 and housed inside by the protrusion 4, is configured so as not to fly out.

Also, the cartridges in magazine 1 are automatically loaded/
When the magazine 1 is set in a magnetic tape device that is unloaded and processed continuously, the lid 5 is lifted up by a projection on the device side (not shown) and the inside of the magazine 1 becomes as shown in FIG. The cartridge 2 is configured to be freely inserted and removed. Note that 7 is a handle that is used for transporting the magazine 1.

[Problem that the invention seeks to solve]

In the conventional magazine 1, the lid 5, which is a means for preventing cartridges from popping out, is constantly pulled downward by a spring 6. Since the lid 5 is fixed only by the spring 6, there is a drawback that the lid 5 moves due to impact during transportation, the protrusion 4 and the cartridge 2 become disengaged, and the cartridge inside pops out.

Also, when storing cartridge 2 in empty magazine 1,
The lid 5 had to be manually lifted and inserted, resulting in poor operability.

[Means for solving problems]

FIGS. 1(A) to 1(F) are diagrams for explaining the present invention in detail.

FIG. 1(A) shows a shaft 8 in which the notches 9a and 9b are at different levels. FIG. 1(b) shows a temporary spring 10 that engages with the notches 9a and 9b, and the cough plate spring 10 is bent into the shape shown, has a roller at the tip, and fixes the base. are doing. Further, the shaft 8 is pulled downward by a spring (not shown), and the plate spring 10 comes into contact with the outer periphery of the shaft 8, as shown in FIGS.

Further, the shaft 8 is rotated 180 degrees as shown in FIGS.

Furthermore, the cartridge 2 is unlocked by moving the shaft 8 upward to engage the temporary spring 10 and the lower notch 9b.

[Effect]

That is, in the locked state shown in FIGS. 1(c) and 1(d), the leaf spring 10 hits the shaft 1 and cannot be bent in the direction of the arrows, so the cartridge 2 is stopped and locked.

In the unlocked state shown in FIG. Can be moved and unlocked.

Note that the lock is unlocked in the same manner as above by lifting the shaft 8 and engaging the leaf spring 10 with the lower notch 9b.

〔Example〕

Figures 2 (a) to (c) show embodiments of the present invention, and (a)
is a perspective view, (b) is a view showing the back side, and (c) is a view (b)
It is an AA sectional view of. Note that the same parts are denoted by the same reference numerals throughout the drawings.

In Figure 1 (A), there is a window 13 so that you can see that it is made of plastic etc., and the rear part is shown in Figures 2 (B) and (A).]
A shaft 8 having notches 9a and 9b at different levels is provided so as to be movable in the vertical direction, and a knob 17 for rotating the shaft 8 is provided on the upper part of the shaft 8. Furthermore, the shaft 8 is pulled downward by a spring 18. A leaf spring 10 that engages with the notches 9a and 9b
The temporary spring 10 (see FIG. 1(B)) has a roller at its tip, is bent in the direction in which the roller 11 is released, and is fixed at its base. [See Figure 1 (C) and (D)] Since the leaf spring 10 contacts the outer periphery of the shaft 8 and cannot be bent, the cartridges 2 in the magazine 12 are securely locked by the rollers 11 and will not pop out during transportation. Things will disappear.

When the magazine 12 is set in the device, the shaft 8 engages with a protrusion 19 provided on the device side, the shaft 8 is lifted and the temporary spring 10 engages with the cutout 9b below, and the temporary spring 10 but〔
(See FIG. 1(E)) Since it can be bent, the cartridge 2 becomes movable and can be taken in and out of the apparatus through the outlet 16. Therefore, unlocking can be easily performed by simply mounting the magazine 12, and therefore reliability is high when used within the device.

In addition, when storing the cartridge 2 in the empty magazine 12, when the operator turns the knob 17 of the shaft 8 by 180 degrees,
The notch 9a on the back side engages with the temporary spring 10, and the leaf spring 10
By bending, the cartridge 2 is unlocked.

Thereby, the operator can insert the cartridge 2 into the magazine 12 without having to manually lock/unlock it as in the conventional case.

〔Effect of the invention〕

As explained above, according to the present invention, the notch in the shaft provided at the entrance/exit of the magazine and the leaf spring that engages with the notch serve as the stopper of the cartridge, and the deflection of the leaf spring is prevented by rotating and moving the shaft in the axial direction. By regulating the cartridges, the cartridges in the magazine can be reliably locked, preventing the cartridges from popping out during transportation, and also making it easy to unload the cartridges, resulting in high reliability when used within the device.
