Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk cartridge, and more particularly to a surface structure of a cartridge case for storing a disk-shaped recording medium.

[Conventional technology]

Conventionally, disk-shaped recording media such as magnetic disks and optical disks are placed in a hard plastic cartridge case in order to protect them from dust and other foreign substances, and to make them easier to handle when mounted on and stored in a disk drive. 2. Description of the Related Art There is known a disk cartridge which is rotatably housed, and in which a disk-shaped recording medium can be mounted on a disk drive while being housed in a cartridge case.

As another example, a disk-shaped recording medium is stored in a cartridge case so that it can be inserted into and removed from the cartridge case, the cartridge case is inserted into a disk drive, and the disk-shaped recording medium is mounted on the disk drive. 2. Description of the Related Art Disk cartridges that are removed from a driving device are known.

This type of disk cartridge grips the rear end of the disk cartridge (the part opposite to the end inserted into the disk drive) with fingers when the disk cartridge is mounted on or taken out of the disk drive. It is operated by.

[Problems to be solved by the invention]

However, in the conventional disk cartridges described above, since the outer surface of the cartridge case is formed smoothly, the fingers are easy to slide when gripped, so that it can be dropped during handling or can be securely attached to and detached from the disk drive. There is a problem that there is no case.

In addition, since the outer surface of the cartridge case is formed smoothly, the contact area between the fingers to be gripped and the surface of the cartridge case is large, and there is a problem that dirt on the fingers is easily transferred. In particular, in a disk cartridge of a type in which one label is stuck around the rear end surface of the cartridge case from the front surface to the back surface of the cartridge case, dirt on fingers is directly transferred to the label, and the appearance is significantly impaired. Not only will it be lost, but the information on the label will be lost or difficult to read. Also, on the back side of the cartridge case, since the finger touches the sticking end of the label, there is a problem that the label is easily peeled off.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned drawbacks of the related art, and has as its object to provide a disk cartridge which is easy to handle and inconspicuous.

[Means for solving the problem]

In order to achieve the above object, the present invention forms a shallow concave portion for attaching a label to an outer surface of the cartridge case in a disk cartridge comprising a disk-shaped recording medium stored in a cartridge case, Irregular non-slip is applied to a portion behind the concave portion, and the tip of the ridge forming the non-slip is disposed outside the surface of the concave portion.

[Action]

If the outer surface of the cartridge case is provided with a non-slip surface, it is possible to prevent slippage when handling the disk cartridge, thereby preventing inconveniences such as dropping during handling and uncertainty of the operation of attaching / detaching to / from the disk drive. In addition, when the uneven non-slip is formed, the contact area between the finger and the grip portion is reduced, so that the dirt transferred from the finger to the cartridge case becomes less noticeable. Further, a shallow concave portion for attaching a label is formed on the outer surface of the cartridge case, and an uneven slip is applied to a rear portion thereof, and a tip of a peak portion constituting the slip preventive is located outside the surface of the concave portion. When the rear end portion of the cartridge case is gripped, even if the tip portion of the finger projects toward the recessed portion, the finger is less likely to touch the label, and the label is prevented from being soiled and peeled. Further, since it is difficult for the finger to touch the label, the area for forming the slip stopper can be narrowed and the area for forming the recessed portion can be widened, so that a label having a large writing area can be attached.

As shown in FIG. 3, the cartridge case 2 includes an upper case 4 and a lower case 5 which are formed in a substantially shallow dish shape and have substantially the same shape and the same size, and are formed by joining these two cases 4 and 5 together. Components such as the disk-shaped recording medium 1 are stored in the space to be formed.

A shallow concave portion 6 for housing the shutter 3 is formed in a portion extending from the front end A of the upper case 4 and the lower case 5 to the middle of the surface, and head insertion holes 7 and 8 are opened substantially in the center. Have been. Further, between the rear end of the concave portion 6 and the rear end B of the upper case 4, a maker name and a model of the disc cartridge are printed, and a blank portion for the user to write required items. A shallow recessed portion 10 for attaching a label 9 provided with a mark is formed. Further, a portion extending from the rear end of the recessed portion 10 to the rear end B of the upper case 4 and a portion facing the lower case 5 have a mountain portion 13a extending linearly in the width direction of the cartridge case. The non-slip 13 is formed by alternately forming the valleys 13b. As is apparent from FIG. 3, the tip of the peak 13a is located outside the surface of the recess 10 and outside the surface of the label 9 attached to the recess 10. Have been. The configuration of the slip stopper 13 is not limited to this, and the slip stopper 13 can also be formed by subjecting the area to graining or forming the surface of the area to have a satin finish. In addition, a spindle hole 12 for opening a center hub 11 set at the center of the disc-shaped recording medium 1 to the outside is formed in the center of the lower case 5.

The shutter 3 is formed in a substantially U-shape with two face plates 14 and 15 covering the surface of the upper case 4 and the surface of the lower case 5 and a connecting piece 16 connecting one end of the face plates 14 and 15.
