Abstract

PURPOSE:To prevent the lowering of the cleaning function of a cleaner mat by movable providing the cleaner mat in a cartridge case having an opening in a position opposed to the optical pick-up of an optical disk device. CONSTITUTION:When the cartridge is set to the optical disk device at the time of using, since a cam part 4a of a shutter 4 with a cam presses a back support 5, the back support 5 presses the back surface of a cleaner mat 3, the pressed part of the cleaner mat 3 is projected at an opening 1a side of a cartridge case 1, it is brought in contact with the optical pick-up, and sure cleaning is executed. At the time of non-using, since the surface of the cleaner mat 3 is not press-contacted to the inner surface of the cartridge case 1, a peculiarity is not given to a fur and a fiber, and consequently, the cleaning function of the cleaner mat 3 can be maintained for a long period.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cleaning cartridge for cleaning an optical pickup of an optical disc device.

(Prior Art) As the optical pickup of an optical disk device is used, dust and the like gradually adhere to it, degrading the optical writing and continuous output functions, so it is necessary to clean it as appropriate. In order to easily and reliably clean this optical pickup, a cleaning cartridge has been proposed that can be attached to an optical disc device and cleaned in the same way as an optical disc cartridge (for example, Japanese Patent Laid-Open No. 63-31
3378, JP-A-64-30084, etc.).

By the way, in the case of a floppy disk device, a sheet with a cleaning function is placed in the same container as the floppy disk, and this can be attached to easily clean it, but in the case of an optical disk device, If such a sheet is simply placed in a cartridge case, it will not make good contact with the optical pickup, and the purpose of cleaning will not be achieved.

Therefore, it is conceivable to use a member such as a brush or mat (hereinafter referred to as a cleaner mat) in which soft bristles, fibers, etc. stand up, protrude from the opening of the cartridge, and come into contact with the optical pickup.

(Problem to be Solved by the Invention) However, the cleaner mat with such a structure can be used for a long time without using the cartridge. If left unused, the surface of the mat will remain in contact with the inner surface of the cartridge case, causing curls in the bristles and fibers, resulting in a decrease in cleaning performance.

The present invention solves these problems, and when not in use, the surface of the cleaner mat is not pressed by the inner surface of the cartridge case, but when in use, it protrudes into the opening of the cartridge case to ensure reliable contact with the optical pickup. An object of the present invention is to provide an optical pickup cleaning cartridge.

(Means for Solving the Problems) In order to achieve the above object, there is provided a cartridge case having an opening at least at a position facing an optical pickup of an optical disc device, and a cleaner mat movably provided within the cartridge case. and a means for pushing the cleaning mat from the back surface to bring the mat surface into contact with the optical pickup when the cleaning cartridge is set in the optical disc device.

(Function) According to this configuration, when the cleaner mat is not in use, the surface of the cleaner mat is not pressed by the inner surface of the cartridge case, so the hairs and fibers do not get stuck, and therefore, the cleaning function can be maintained for a long time. When in use, a portion of the mat surface protrudes into the opening of the cartridge case, so
The mat and the optical pickup come into good contact, and leaning is performed reliably.

(Example) Hereinafter, embodiments will be described in detail based on the drawings.

FIG. 1 shows an embodiment of the present invention, in which numeral 1 denotes a cartridge case having an opening 1a at least at a position facing an optical pickup of an optical disc device, 2 a shutter provided in the opening 1a, 3 4 is a cleaner mat movably provided inside the cartridge case 1; 4 is a shutter with a cam provided on the rear surface of the cartridge case 1;
Reference numeral 5 denotes a cylindrical back support disposed between the inner surface of the cam-equipped shutter 4 and the back surface of the cleaner mat 3.

The cleaner mat 3 can be a cloth, a nonwoven fabric, or a brush-like material made of a sponge or sheet with fluff on its surface. The shutter 2 closes the opening 1a to prevent dirt from adhering to the mat surface when the cleaning cartridge is not in use, and opens when the cleaning cartridge is set in the optical disc device. Similarly, when the cleaning cartridge is set in the optical disc device, the cam-equipped shutter 4 moves so that the cam part 4a comes to the center as shown in FIG. 1(b), and the cam part 4a pushes the back support 5. It has become.

In this embodiment configured in this manner, as shown in FIG. 1(a), when the cleaner mat 3 is not in use, the surface of the cleaner mat 3 does not come into pressure contact with the inner surface of the cartridge case 1, so hairs and fibers do not get stuck. Therefore, the cleaning function can be extended for a long time. In addition, when used, when the optical disc is set in an optical disc device, the cam part 4a of the cam-equipped shutter 4 pushes the back support 5, as shown in FIG. When the cleaning mat 3 is pressed, the pressed portion of the cleaner mat 3 protrudes toward the opening 1a side and makes good contact with an optical pickup (not shown), thereby ensuring reliable leaning.

FIG. 2 shows another embodiment of the present invention, in which the same reference numerals as in FIG. be.

In this embodiment configured in this manner, as shown in FIG. 2(a), when the cleaner mat 3 is not in use, it is not subjected to any external force, so that its surface does not come into pressure contact with the inner surface of the cartridge case 1. Therefore, the hair and fibers do not become sticky. Also,
When it is set in the optical disc device during use, the
) as shown.

The hook part 6a of the hooked shutter 6 is the back support 7
Hook one end and curve it, so back support 7
presses the back of cleaner mat 3.

The pressed portion protrudes toward the opening 1a and makes good contact with the optical pickup. This embodiment also has the same effects as the embodiment shown in FIG.

(Effects of the Invention) As explained above, according to the present invention, even if the cleaning cartridge is left unused for a long time,
Since no external force is applied to the surface of the mat, the hairs and fibers do not become tangled, and the cleaning function does not deteriorate. Furthermore, during use, a portion of the cleaner mat protrudes and makes good contact with the optical pickup, so that leaning can be performed reliably.
