Abstract: A disk cartridge includes a case accommodating a disk and having a first hole, a cover installed at the case and having a second hole open to an outside of the cover, a shutter installed to be capable of moving with respect to the case disposed under the disk to open/shut the first hole formed on the case, and a plurality of protruding portions provided at the shutter to support a non information area provided at an outer circumferential side of the disk and having inclined surfaces inclined at a predetermined angle. When the shutter is opened, the disk descends along the inclined surfaces. When the shutter is shut, the disk ascends along the inclined surfaces to closely contact a portion of the cover disposed around the second hole of the cover. Thus, since the shutter contacts only a non-information area of the disk, an information area of the disk can be safely kept from being damaged during an operation of opening/shutting the first hole. Also, since an edge portion of the outer circumferential side of the disk closely contacts a sealing member disposed around the second hole of the cover in a state that the shutter is shut, a gap through which dust can intrude is blocked, so that contamination of the recording surface can be reduced.

Abstract translation: 磁盘盒包括容纳盘并具有第一孔的壳体，安装在壳体处的盖，并且具有通向盖的外部开口的第二孔;安装成能够相对于设置在壳体下方的壳体移动的挡板 盘，以打开/关闭形成在壳体上的第一孔，以及多个突出部分，设置在快门处，以支撑设置在盘的外圆周侧的非信息区域，并具有以预定角度倾斜的倾斜表面。 当快门打开时，盘沿倾斜表面下降。 当快门关闭时，盘沿着倾斜表面上升，以紧密接触设置在盖的第二孔周围的盖的一部分。 因此，由于快门仅接触盘的非信息区域，因此在打开/关闭第一孔的操作期间可以安全地防止盘的信息区域被损坏。 此外，由于盘的外周侧的边缘部分在快门关闭的状态下与设置在盖的第二孔周围的密封构件紧密接触，所以可以阻挡灰尘可以侵入的间隙，使得污染 可以减小记录表面。

Abstract: A disc cartridge includes a shutter unit having an outer shutter and inner shutters to open and shut apertures on the disc cartridge. The outer shutter opens one of the inner shutters corresponding to a side of the disc cartridge being accessed by a pickup. Accordingly, the overall area of the apertures exposed to the exterior during information recording and reproducing operations is reduced. Accordingly, dust is less likely to enter into the disc cartridge.

Abstract: A laser scanning unit (LSU) in a structure capable of radiating heat generated by a light source. The LSU includes at least one light source, a driving source for providing rotational force, and a deflection disk installed on a rotary shaft of the driving source, for diffracting and deflecting light incident from the light sources. The deflection disk has at least one radiating portion which is depressed in and/or protrudes from the surface of the deflection disk facing the light source and induces air flow by contact with air, such that the heat generated by the light sources is radiated by the air flow induced due to the radiating portion.

Abstract: A reel table moving mechanism selectively receives tape cassettes having different sizes. The mechanism includes a deck member in which a head drum and a tape guiding unit are installed and having first and second openings formed to be spaced from each other, each having a predetermined length. A pair of reel tables, operative to move along the first and second openings, selectively receive first and second tape cassettes of a different size. Each reel table has a stopper for locking a pair of reels and a releasing lever for releasing the stopper. A pair of first and second reel bases on which the reel tables are mounted are slidably supported to the deck member. First and second shafts are supported by a supporting mechanism at one side of each of the first and second openings and are slidably connected to the first and second bases. A mechanism moves the first and second reel bases, and first and second releasing devices release each releasing lever of the first and second tape cassettes from being locked. According to the above mechanism, the structure is simplified, and the reel table can be stably maintained.
