Problems solved by technology

[0020] However, to make Figure 15 The shown rod-shaped driving means 250 slides close to the side of the cartridge 200, and a space for the driving means 250 to move near the side of the cartridge is required, so it is difficult to arrange the above-mentioned holding member 211R.
Therefore, there is a problem that the disk cartridge 200 cannot be held stably, or the engagement between the driving means 250 and the rotor 204 cannot be reliably performed.

Abstract

A disc drive according to the present invention is adapted to a disk cartridge including: a disk; a body to contain the disk; a window provided for the body to allow a data reading and / or writing head to access the disk; a shutter for opening or closing the window; and a rotational member including a gear as a part of its outer periphery and rotating to open or close the shutter. The drive includes a shutter driving mechanism for opening and closing the shutter by rotating the rotational member of the disk cartridge, and the shutter driving mechanism includes a driving gear, which engages with the gear of the rotational member and which turns around a first rotation shaft. The first rotation shaft swings around the center of rotation of the rotational member of the disk cartridge that is held on the holding portion.

Description

technical field [0001] The present invention relates to a disc device for recording on and / or reproducing from a data recording medium such as an optical disc or magnetic disc accommodated in a cartridge-type housing. Background technique [0002] Currently, various disc-shaped data recording media are widespread. For example, CD, DVD, DVD-RAM, etc. are examples of media for recording and / or reproduction using optical beams, and floppy disks are examples of media for recording and / or reproduction using magnetic fields. In addition, recording and / or reproducing MO or MD using light beams and magnetism is also popular. [0003] Among these disc-shaped data recording media, data recording media such as DVD-RAM and MO are accommodated in a cartridge to protect the data recording surface. As an example of such a cartridge, Japanese Patent Application Laid-Open Publication No. 9-153264 discloses Figure 10 Cartridge shown. [0004] The disc cartridge 100 has a cartridge body 10...
