Abstract

(57) [Abstract] [Purpose] The disc cartridge is quickly detached from the shutter opening / closing operation pin so that the hinge part can move up and down without forming a gap near the hinge part of the disc cartridge in which the upper case and the lower case are integrally molded. Assemble and integrate the case. A disk-shaped medium is rotatably housed in a case 2 composed of an upper case and a lower case provided with a window part, and a shutter for opening and closing the window part is slidably provided in the case 2, and the shutter of the shutter is provided. A disc cartridge having a V-shaped notch portion (11) for locking on the front side of the case with which the opening / closing operation pin abuts. A part of the pin abutting surface reaching the V-shaped notch portion (11) faces the opening direction of the shutter. By forming the slope 12 with a downward slope, the shutter opening / closing operation pin can be quickly detached from the shell, the ejectability of the cartridge can be improved, and a light operation for handling can be guaranteed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a disc cartridge in which a disc-shaped medium such as a flexible disc or a hard disc is rotatably housed in a case.

[0002]

[Prior art]

 Generally, a flexible disk or a hard disk as an information recording carrier is easily scratched, and dust or dust is easily generated, so that it is handled as a disk cartridge housed in a case with a shutter and easily set by a recording / playback device. It is configured. Conventionally, in this type of disc cartridge, an upper case and a lower case are separately formed, and a disc-shaped medium is housed inside to fuse the upper case and the lower case.

[0003]

[Problems to be solved by the device]

 However, in this disc cartridge, when the hard disk is loaded and set, the shutter on the case is slid in the opening direction by the operation pin, but in order to maintain the open state of the window part provided in the case. A V-shaped notch for locking is formed on the front surface of the case with which the shutter opening / closing operation pin abuts. That is, in the conventional shell, as shown in FIG. 4, the front side surface of the case c with which the shutter operating pin abuts is a straight surface a parallel to the sliding direction of the shutter and is continuous with the V-shaped notch portion b. In addition, the shutter opening / closing operation pin came out of the shell slowly, and it took time to discharge the shell from the hardware side, and there was a lack of good discharge, which was a problem in handling. The present invention is intended to eliminate these conventional drawbacks.The shutter opening / closing operation pin is quickly disengaged from the shell to improve the ejectability of the cartridge, and the operation is easy and easy to handle. The purpose is to provide a disc cartridge of

[0004]

[Means for Solving the Problems]

 According to the present invention, a disk-shaped medium is rotatably housed in a case consisting of an upper case and a lower case provided with a window section, and a shutter for opening and closing the window section is slidably mounted on the case. In a disk cartridge having a V-shaped notch portion for locking on the front side of the case with which the opening / closing operation pin comes into contact, a part of the pin abutting surface reaching the V-shaped notch portion is directed toward the opening direction of the shutter. A disk cartridge characterized by being formed on a slope having a downward slope.

[0005]

[Action]

 When the disk cartridge is loaded and set in the hard side, the shutter on the case is slid in the opening direction by the operation pin, the operation pin is fitted into the V-shaped notch, and the window part provided on the case is in the open state. To maintain. When the disk cartridge is taken out, the operation pin is operated to remove it from the V-shaped notch portion, and the operation pin is put on the slope and quickly disengages, so that the cartridge can be ejected satisfactorily and light handling is possible.

[0006]

【Example】

 1 to 3, an embodiment of the present invention will be described. A disk-shaped medium 1 is rotatably accommodated in a case 2 composed of an upper case and a lower case provided with a window part 3, and the window part 3 described above is used. A disc cartridge having a shutter (4) for opening and closing is slidably mounted on the case (2), and a V-shaped notch portion (11) for locking is provided on a front side surface of the case with which an opening / closing operation pin of the shutter (4) contacts. A part of the pin abutting surface reaching the notch 11 is formed as a slope 12 having a downward slope in the opening direction of the shutter to form a disk cartridge.

In this case, it is preferable that the slope 12 has a downward slope with an inclination angle θ in the range of 1 to 3 degrees and is connected to the V-shaped notch portion 11. Further, the shutter 4 has a substantially U-shaped cross section, and a window hole 5 is formed on the shutter plate, and the shutter 4 is slidably fitted in the shutter slide area 6 so as to match the window portion 3.

In the figure, 7 is a liner, 8 is a disc hub fitting hole, 9 is a medium housing portion, 10 is a disc hub, 13 is a label area, and 14 is a case welding boss.

[0009]

[Effect of device]

 According to the present invention, a disk-shaped medium is rotatably housed in a case consisting of an upper case and a lower case provided with a window section, and a shutter for opening and closing the window section is slidably mounted on the case. In a disk cartridge having a V-shaped notch portion for locking on the front side of the case with which the opening / closing operation pin comes into contact, a part of the pin abutting surface reaching the V-shaped notch portion is directed toward the opening direction of the shutter. By forming on the slope with a downward slope, the shutter opening and closing operation pin can be quickly removed from the shell, the dischargeability of the cartridge can be improved, and the operation is easy to handle, and the upper case and lower case can be molded. It has practical effects such as easy processing and assembling work, improved accuracy, and easy mass production.
