Abstract

Disclosed is a device that is an air-type optical system cleaner for an optical disk drive to prevent drive performance degradation due to particulate contamination. This device can clean both an object lens and a beam bender at the same time which are critical parts in the drive for contamination. Also it can be operated with one hand and does not require any electrical power.

Air Type Optical System Cleaner for Optical Disk Drive

       Disclosed is a device that is an air-type optical system
cleaner for an optical disk drive to prevent drive performance
degradation due to particulate contamination.  This device can clean
both an object lens and a beam bender at the same time which are
critical parts in the drive for contamination.  Also it can be
operated with one hand and does not require any electrical power.

      The disclosed device will be best understood with reference to
the drawings.  In Fig. 1, the main body 4 is made similar to an
optical disk cartridge to locate two openings 5 and 6 being the best
position.  Blowing air is made by pushing a box 1 and a pump 2.  The
blowing air passes through a tube 3 which is in main body 4 and then
goes out from the two openings 5 and 6.

      How to use this cleaner is described as follows.  A cleaner is
inserted into an optical disk drive.  When the cleaner comes to the
end of the optical disk drive, two openings 5 and 6 are right above
an object lens 7 and a beam bender 8 (Fig. 4).  Then, if a box
1 is pushed, air from the opening 5 blows against the object lens 7
and air from the opening 6 blows against the beam bender 8. In Fig.
4, heavy lines show air flowing paths.

      Fig. 3 shows the magnified top view of the area around the
openings.  Fig. 2 shows an another type of cleaner with a different
pump.

      The following are the advantageous effects which ar...
