Abstract

PURPOSE: To easily confirm the empty storage place of a storage disk by fixing a manual adjusting knob for setting a scale and a scale value outside a protecting housing, and setting this knob so that the full storage content of the storage disk can be viewed from outside. CONSTITUTION: A label 4 equipped with a pocket 9, vertical slit 7, and scale 6 in neighborhood parallel to a side edge 5 of a case 1 is stuck to a flat face opposite to a slide 2 of the case 1. A colored manual adjusting knob 8 is inserted under the slit 7 of the pocket 9, and the knob 8 is moved and set according to the scale according to the full storage capacity of the floppy disk. The pocket 9 is formed by folding the end part of the side edge 5 side of the label 4 at 180 deg., and bonding and fixing a strip 10 folded at 180 deg. again to the label 4. Thus, the empty and full storage contents of the floppy disk can be easily confirmed from outside.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floppy disk comprising a storage disk and a protective jacket.

[0002]

2. Description of the Related Art A floppy disk is a highly-used computer storage medium. Unlike a fixed disk memory (fixed disk), a floppy disk is stored outside the computer and is inserted into an appropriate drive mechanism of the computer only when necessary. As a result, the storage disk of the floppy disk must have a protective jacket. The protective envelope usually consists of paper for a 5,25 inch floppy disk and a hard case for a 3,5 inch floppy disk.

The floppy disk is usually stored in a storage box or the like provided for that purpose. If the floppy disk is partially used, there is room in some circumstances for another program or for storing another data. In that case, if there is information about the required storage capacity, by inserting a floppy disk into the drive mechanism with today's technology and reading the indication of the blocked storage location on the computer screen, the relevant floppy disk will still have sufficient storage location. You have to see if there is.

If several floppy disks have been tested but do not have sufficient storage space and therefore the above procedure has to be repeated, the procedure is cumbersome and time consuming.

[0005]

Therefore, it is a common practice to stop testing free disk floppy disk locations and record new data or programs on a new floppy disk. In that case, the optimum use of the storage location provided by the floppy disk is impossible.

[0006]

Starting from this problem, a floppy disk of the type mentioned at the outset according to the invention, starting from this problem, features a scale mounted on the outside of the protective casing and a manually adjustable knob for setting the scale value. And

In that case, it is preferable to set the scale according to the number of bytes available on the floppy disk. In this way, before or after recording the program and the data to be recorded on the floppy disk, it is possible to manually set the storage capacity of the floppy disk on the scale. It is already visible from the outside in a storage box such as a floppy disk if there is still enough storage space for.

Today's 3,5-inch floppy disks have a hard plastic case. In such a floppy disk, it is preferable to pass a graduation slide through the case itself. For a simple structure, a guide slit is provided parallel to the side of the case for this purpose. The protruding part of the slide surrounding the side edge is engaged with this guide slit. The slide can then move in the direction of the guide slit. In this case, it is appropriate to attach the scale along with the label to the outside of the case.

In a preferred construction that is easy to manufacture, the slides are U-shaped and are preloaded against each other.
Surround the sides of the case with one leg. An alternative structure that does not require engagement of the floppy disk with the case and can also be used with a paper protective jacket, allows the tabs to move in a flat pocket. This flat pocket can be applied to the outside of the protective jacket. In that case, it is preferable that the flat pocket has a scale. The linear flat indicator in the pocket can be moved under the slit. The scale and the scale value display knob can be formed flat so that the floppy disk can be smoothly inserted into the slit of the drive mechanism thereafter. In that case, the indicator does not interfere with the operation of the floppy disk.

In the preferred construction, the tab is a slide that engages a slit in the applied label. The slide can move over the front surface of the slit and overhang behind the edge of the slit. It is particularly advantageous if the slide has a window on the front of the label, which can be moved over the scale and which encloses the scale numbers in a frame.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 shows a generally square flat case 1 for a storage disk (not shown). If the slide 2 with the window 3 is displaced when it is inserted into the drive mechanism of the computer so that the window 3 is aligned with the window of the case, the storage disk can reach the magnetic head.

A label 4 is attached to the upper flat surface of the case 1. The label 4 is formed with a pocket in the vicinity of the side 5 of the case 1 on the opposite side of the slide 2, and has a scale 6 along with the vertical slit 7. The vertical slit 7 is aligned in parallel with the side edge 5. The colored strip 8 inserted in the pocket can be moved inside the pocket and under the slit 7. Depending on the full storage capacity of the floppy disk, this strip can set the scale value.

FIG. 2 shows a sectional view of the structure of the pocket 9 of the label 4. The end portion of the label 4 on the side 5 side is folded back 180 °, and the strip 10 folded back 180 ° is adhered and fixed to the lower side of the label 4 to form the pocket 9. A flat strip 8 is in the pocket 9
It is formed on the paper tape inserted into the device and can be moved under the slit 7 (FIG. 1) together with the paper tape.

In the structure shown in FIGS. 3 to 5, the label 4'is simply attached to the case 1 of the floppy disk. The label 4'finishes at a distance from the side 5 of the case 1 and has a graduation 6'at its end.

The slide 11 is formed in a triangular shape on the upper side shown in FIG. 3, and its apex projects above the scale 6 '. The slide 11 is guided on the lower side of the case 1 shown in FIG. 4 by a guide slit 12 aligned in parallel with the side edge 5.

FIG. 5 shows that the slide 11 has a U-shaped configuration with two legs 13, 14 which are preloaded against each other. The bottoms 15 of the U-shaped legs 11 are designed so as to be in direct contact with the sides 5 and guided. The lower leg 14 has a protrusion 16 toward the inside of the U-shape. This protrusion engages with the guide slit 12 to guide the slide 11 parallel to the side edge 5.

In the structure of FIGS. 1 and 2, the pocket 9 for accommodating the scale 6 and the strip 8 is attached to the outside of the case 1, so that the case may remain completely unchanged, but in the structures of FIGS. The case 1 must be specially constructed by providing a guide slit 12 and optionally a guide surface for accommodating the slide 11 on the underside of the case.

FIG. 6 shows an alternative construction of the label 4'with a slit 7'parallel to the upper edge. Labels can be attached to the entire surface of the floppy disk envelope. However, there is no adhesive in the area of the slit 7 '. The slide 11 'can move in the slit 7'. Label 4 '
On the front side of the slide 11 'is formed as a rectangular window 17. One side of the inside of the frame of the window 17 is cut off, and it extends through the slit 7'as a projecting edge 18 to the back side of the label 4 '. Therefore, the slide 11 'is operated by the window 17 on the front side of the label 4'and the slit 7'
Overhang behind the edge of the. The high stability of this structure results from the high degree of stability of this structure, especially due to the realization of the overall bonding of the label 4'excluding the area of the slit 7'and the area in which the flaring rim 18 is guided behind the label 4 '.
1'can be made of hard or cardboard.
