Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a magnetic disk cartridge, and particularly to a video disk speaker cartridge for an electronic still camera.

B. Prior Art Electronic still cameras that magnetically record still images use small flexible magnetic disks, and it has become possible to record 25 or more still images on one side of the disk, for example, by frame recording. ing. These electronic still cameras have advantages over cameras using silver halide film, such as requiring no development, being reusable, and being easy to transmit electronically.

FIG. 11 shows a conventional video floppy cartridge (hereinafter sometimes referred to as a cartridge) 9.
1. FIG. FIG. 12 is a plan view of the cartridge 91 viewed from the direction of the arrow, and FIG. 13 is a plan view of the cartridge 91 viewed from the direction of the arrow.

This cartridge 91 is constructed such that an opening 14 is formed on both sides of a plastic cartridge body 13 called a shell, and the floppy disk 9 inside faces the opening 14. When the disk is not in use, the opening 14 is normally formed by a metal shutter 6 having a U-shaped cross section.
Although the disk 9 is not exposed because it is shielded by the opening 14, when the disk is driven (magnetic recording), the shutter 6 is moved to the imaginary line position, and the recording surface of the disk 9 is exposed through the opened aperture 14. I'm starting to do that. Note that the disk 9 is rotatably housed within the main body 13 while being fixed to a center hub 11 attached to a spindle on the driver side. The main body 13 has an upper half 4 and a lower half 5
A recess 12 for label attachment is provided on the surface of the upper half 4 of the main body.

Such a still video float speaker storage is, for example, 2 inches, and measures 5.4 cm x 5.4 cm.
It is small, lightweight, and extremely thin at 6.0 cm x 0.36 cm. In addition, since it is flat and made of smooth plastic, it is difficult to grasp it with your fingers when placed on a smooth table, for example, and it may take time to grasp it or may be missed. It is inconvenient to do so. Particularly in laboratories, work is often done while wearing gloves, but it is extremely difficult to hold the cartridge while wearing gloves, and it is necessary to remove the gloves and then hold the cartridge again. It was very inconvenient to have to grasp it again. Of course, similar problems occur in the winter because gloves are often worn and the motor function of the fingertips deteriorates due to the drop in temperature, and in the summer and rainy seasons, sweating due to high temperature and humidity makes it difficult to grip the cartridge. A problem arises.

C. Purpose of the invention The purpose of the invention is to make it easy to grasp with a simple motion from the state placed on the table, and to be able to hold it on the table even when wearing gloves, in low temperature, hot and humid conditions. It is an object of the present invention to provide a magnetic disk cartridge which can be easily grasped from a placed state.

D. Structure of the invention The present invention provides a magnetic disk cartridge in which notches are provided on at least three adjacent sides of the cartridge body, and the side of the magnetic disk cartridge opposite to the side where the notches are provided. The present invention relates to a magnetic disk cartridge characterized in that one end of the cartridge body is lifted up from the cartridge mounting surface by pressing the surface toward the cartridge mounting surface.

Example Hereinafter, embodiments of the present invention will be described in detail.

1a to 1f show a magnetic disk cartridge 1. FIG. 1A is a perspective view of the cartridge 1 seen from the direction of the lower half 5 of the main body, FIG. 1B is a side view similarly seen from the side of arrow b, and FIG. Figure d is a schematic cross-sectional view taken along line dd in figure a, figure e is a plan view of the cartridge 1 seen from the side of the lower body half 5, and figure f is also seen from the side of the upper body half 4. FIG.

The overall configuration of the cartridge 1 is almost the same as the cartridge 91 described in the section of the prior art, and the same functional members are given the same reference numerals and their explanation will be omitted. In addition, in FIG. 1d, 10 indicates a disk frame, which is omitted from illustration in other drawings.

A characteristic feature of the cartridge 1 is that a triangular pyramid-shaped notch 2 is provided at the lower left corner (outer edge corner) of the lower half 5 of the main body. In this embodiment, by employing such a unique configuration, the following remarkable effects can be achieved.

That is, when cartridge 1 is placed on base 22 with lower half 5 side down, as shown by the solid line in Figure 2, the surface of lower half 5 comes into contact with base 22, but because a triangular pyramid-shaped cutout 2 is provided, the triangular inclined surface (cutout surface) 3 (see Figure 1a) does not come into contact with base 22, and a gap is created in the area of cutout 2.

Next, when gripping the cartridge 1 and lifting it from the stand 22, point the notch position of the upper half 4 of the cartridge 1 toward the stand 22, as shown by arrow D in FIGS. 2 and 3. 20 (indicated by virtual line)
Press with . As a result, the cartridge 1 tilts toward the notch 2 as shown by the imaginary line in FIG.
The slope 3 is in contact with the platform 22 over its entire surface, and at the same time, the surface of the lower half 5 is released from contact with the platform 22 and is lifted in the direction shown by arrow E in FIGS. 2 and 3.

Next, as shown in FIG.
1, and then lift the cartridge 1.

As described above, in the cartridge 1, the notch 2 is provided at the outer edge corner of the lower body half 5, so if the upper body half 4 is pressed toward the stand 22 at this notch position, , the cartridge 1 can be tilted, and therefore the cartridge 1 can be easily grasped and lifted with a simple motion. Moreover, the above-mentioned operation is very simple and can be easily carried out without any problem even when wearing gloves, at low temperatures, at high temperatures and high humidity, etc., for example.

FIGS. 4a to 4c illustrate examples of the shape of the notch as described above.

FIG. 4a is a side view showing the shape of the above-mentioned notch 2, and corresponds to the side views shown in FIGS. 1b and 2. The triangular slope 3 has a linear shape when viewed from the side, and as described above with reference to FIG. We will come into contact. When a cutout having such a shape is used, manufacturing is easy, and the cartridge is considered to be stable in an inclined state.

In FIG. 4b, an arc-shaped notch 2B is provided in the lower half 5B of the main body. According to this example, when the notch position of the upper half of the main body is pressed, the inclination angle of the cartridge with respect to the stand (placement surface) changes smoothly, so it is considered that the pressing force is small.

In FIG. 4c, the cutout 2C provided in the lower half 5C has a substantially rectangular parallelepiped shape. According to this example, even when the notch position of the upper half of the main body is pressed, the notch surface 3C does not come into contact with the stand (placement surface), and the apex angles 16 of the notches 2C facing each other, The base and the lower half 5C contact each other at the portion corresponding to the apex angle 17, so that the cartridge body is supported at three points at the portions corresponding to the apex angles 16 and 17. In this example as well, it is considered that when the upper half of the main body is pressed, the cartridge can be stably supported in an inclined state.

FIG. 5 illustrates an example of a position where the above-mentioned notch can be provided.

The overall configuration of the cartridge 31 is similar to that of the cartridge 1. In the lower half 35 of the main body of the cartridge 31, an area 3 indicated by a dashed line in the figure
Any of 2, 36, and 37 can be provided with a cutout as described above, thereby achieving the same effect as described above. Of course, it is also possible to provide notches in two or more of the regions 32, 36, and 37.

Further, it is also possible to provide a notch having a triangular prism-like cross section, for example, in the region 38 shown by the two-dot chain line in FIG. In this case, for example, as shown by arrow F, it is possible to press two or more places with your fingers at the same time, making it easier to tilt the cartridge.

Furthermore, it is also possible to provide a notch having a triangular prism-like cross section, for example, in the region 39 shown by the three-dot chain line in FIG. In this case, since a notch is provided around the entire circumference of the lower half 35 of the cartridge body, the cartridge can be tilted by pressing any position on the periphery of the main body, which eliminates the trouble of confirming the position to be pressed. There is an advantage that it can be saved.

FIG. 6 shows an example of a position where the above-mentioned notch can be provided in the upper half 44 of the cartridge.

The overall structure of the cartridge 41 is also the same as described above. In this main body upper half 44, regions 42 and 4 indicated by a dashed line, a dashed double dot line, or a dashed three dot line.
Any of 6, 47, 48, and 49 can be provided with a notch as described above. Of course, it is also possible to provide notches in two or more of the regions 42, 46, 47, and 48.

By providing the notch in the upper half 44 of the main body in this way, even when the cartridge is placed on a stand with the upper half of the main body facing down, it is possible to completely eliminate the problem as described above using FIGS. 2 and 3. Similarly, by pressing the notch position on the surface of the lower half of the main body, the cartridge can be tilted, and therefore the same effect as described above can be achieved. A label is usually affixed to the top half of the main body, so it is assumed that the cartridge is placed on the stand with the top half of the main body facing upward, but in reality it may be placed in the opposite direction. The cartridge 41 shown in FIG. 6 is suitable for such cases.

In addition, in FIGS. 5 and 6, each area 32,
The shapes of 36, 37, 38, 42, 46, 47, and 48 do not necessarily indicate the shape of the cutout that can be provided in each region.

FIG. 7 is a plan view showing another cartridge 51.

The overall structure of the cartridge 51 is similar to the cartridge 1 shown in FIG. A characteristic feature of the cartridge 51 is that a special label 53 is attached to the label attachment recess 12. That is, although the display 19 is printed on the label 53 as in a normal label, the surface of the label 53 is roughened at the right end of the label 53, that is, around the notch position of the upper half 54 of the main body. Cage, small unevenness 5
5 are provided in large numbers. Therefore, when pressing the notch position of the upper half 4 of the main body to tilt the cartridge 51, the frictional force between the fingertips and the small irregularities 55 acts, so the fingertips do not slip and there is no need to apply unnecessary force to the fingertips. There is no. This is particularly suitable in hot and humid conditions or when wearing slippery rubber gloves.

FIG. 8a is a plan view showing still another cartridge 61, and FIG. 8b is a sectional view taken along line bb--b in FIG. 8a.

The structure of the cartridge 61 is also the same as that described above, but in the upper half 64 of the main body, the label pasting recess 62 has a shape with the right end removed compared to the one described above, and the area of the recess 62 is is getting smaller. However, 63 is a label on which display 19 is printed.

A right triangular anti-slip recess 67 is provided at the lower right corner of the upper half 64 of the main body, that is, at the notch position where pressing is to be performed. The recess 67 is the bottom surface 6
5 and a wall surface 66, and the bottom surface 6
5 is inclined toward the outer edge of the main body. When tilting the cartridge 61 placed on the table, all you have to do is place your fingertips on the bottom surface 65 and wall surface 66 of this recess 67 and press in the direction shown by arrow G. At this time, the wall surface 66 allows your fingertips to slide. Since this is prevented, the cartridge can be tilted more reliably, and the same effects as the cartridge 51 in FIG. 7 can be achieved.

FIG. 9 is a plan view showing still another cartridge 71.

This cartridge 71 also has the same structure as the cartridge 1 shown in FIG. However, the upper body half 74 is molded from transparent plastic so that the interior of the cartridge is visible from the outside. Main body upper half 7
4 may be molded in smoke color, for example. Another notable feature is that the display section 73 is provided on the inner wall surface of the upper half 74 of the main body. That is, the display 19 is sandwiched between the display section 73 and the inner wall surface of the upper half 74 of the main body, and since the upper half 74 is transparent, the display 19 and the display section 73 can be recognized with the naked eye from the outside. It can be done. upper half 74
The display section can be provided on the inner wall surface of the display panel by, for example, in-mold molding, hot pressing, pasting a label on the inner wall surface, stamping, baking, or the like. Note that the surface of the upper half 74 may be made smooth in the portion corresponding to the display portion 73, and the other portion may be frosted glass-like.

According to this example, the display section 73 is
4 and is not exposed to the outside of the main body, so even if you press the lower right end of the upper half 74 of the main body, that is, the notch part, with your fingertips to hold the cartridge 71 at an angle, your fingertips will not touch the display area. 73 is not touched directly, therefore, the display section does not deteriorate such as staining or abrasion, and a good display state can be maintained for a long period of time. Particularly, even in high temperature and high humidity conditions, the display section is not stained by pressure from sweaty fingertips, which is considered to be advantageous.

FIG. 10 is a perspective view showing still another cartridge 76 and storage sleeve 81.

The overall structure of the cartridge 76 is also similar to the cartridge 1 shown in FIG. 1, but in the cartridge 76, a notch 77 is provided at the corner opposite to the cartridge 1 in the lower part of the lower half 5 of the main body.

The overall structure of the storage sleeve 81 is almost the same as that normally used, and has an opening 83 and a notch 82 provided on one side of the main body 84. The dimensions of the storage sleeve 81 match those of the cartridge 76, so that the cartridge 76 can be fixed in the stored state. In addition, when the cartridge 76 is stored, a part of the main body upper half 4 and lower half 5 (the upper left part in the drawing) is exposed through the notch 82, so that when the cartridge 76 is taken out from the sleeve 81, All you have to do is grasp the exposed part with your fingertips and pull it.

A distinctive feature of this sleeve 81 is that a notch 85 is provided at the lower right corner in the drawing. The shape and dimensions of this notch 85 are matched to the notch 78 provided in the cartridge 76, so that the cartridge 7 can be inserted into the sleeve 81.
6 is housed as shown by arrow H, the sleeve 8 corresponding to the part where the notch 85 is provided
The slope (notch surface) 78 is in close contact with the inner wall surface 86 of the first.

In this example, by configuring the sleeve 81 as described above, even when the cartridge 76 is housed in the sleeve 81 and placed on the table with the surface 84b facing down, the main body 84 The sleeve 81 can be tilted by pressing the cutout position of the surface 84a toward the mounting surface, and the sleeve 81 can be easily grasped and lifted. These storage sleeves are usually 5.6cm x 6.1cm x
Since the size is about 0.46 cm, the same problem as the above-mentioned cartridge may occur when placed on a table.

Although the present invention has been illustrated above, the embodiments of the present invention are not limited to those described above, and various modifications can be made based on the technical idea of the present invention.

For example, the shape, number, position, etc. of the notches may be various, and the notches may be provided on both the upper half and the lower half of the main body. The planar shape of the notch may also be other than a triangle, such as an arcuate shape.

In the example shown in FIG. 9, a mirror surface may be provided in place of the display portion 73, and an anti-slip recess as shown in FIG. 8 may be provided at the cutout position on the surface of the upper half 74 of the main body.

The present invention is also applicable to other magnetic disk cartridges.

Effects of the invention According to the magnetic disk cartridge of the invention,
A magnetic disk cartridge in which a notch is provided on at least three adjacent sides of a cartridge body, the surface of the magnetic disk cartridge opposite to the surface provided with the notch facing toward the cartridge mounting surface. By pressing, one end of the cartridge main body is lifted off the above-mentioned placement surface, so the cartridge placed on the placement surface can be tilted and the tilted cartridge can be easily moved with a simple operation. can be grasped. Moreover, since this operation is very simple, it can be easily performed without any problem even when wearing gloves, at low temperatures, and at high temperatures and high humidity.
