Abstract

PURPOSE:To record, reproduce and erase information always in a good condition by providing the cleaning means of a card-shaped recording medium in the neighborhood of the inserting hole of the recording medium. CONSTITUTION:When a card-shaped recording medium 4 is inserted, a brush part 1b rotating in the same way as a loading roller 1 removes foreign matters 6 which adheres to the recording medium 4 as keeping contact with the recording face of the recording medium 4. At this time, all of static electricity charged on the recording medium 4 flows properly into an earth line provided for the main body of the title device through the brush part 1b and the static electricity is completely removed, at the same time. Next, the foreign matters 6 get into a foreign matter housing case 7 fitted at the rear of the loading roller 1.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an optical information recording/reproducing device that records, reproduces, or erases information by irradiating a light beam onto a card-shaped recording medium. be.

2. Description of the Related Art Conventionally, optical discs housed in hard cases have been commercially available as optical information recording media. The hard case is equipped with a shutter mechanism that can be opened and closed, and when the hard case is inserted into the optical disk device, the shutter opens, and when the hard case is ejected, the shutter is closed. Even with such an optical disc, when the shutter is opened and closed, dirt and dust enter the inside of the node case and adhere to the surface of the optical disc. Dirt and dust attached to the recording surface are firmly attached to the surface due to static electricity generated when the optical disk rotates at high speed. In this state, when a light beam is irradiated onto the optical disc, the light beam is blocked by the attached dirt and dust, and the light beam does not reach the recording layer of the optical disc accurately. Because it is re-done by dirt and dust, noise is generated in the playback signal,
A problem occurred in which information could not be accurately recorded, played back, or erased. This tendency is even more pronounced in optical information recording media that do not have a node case, such as compact discs and optical cards. In addition, in the past, dust-proof X7"L/- etc. were used to artificially clean these adhering dirt and dust, but it was very troublesome and required cleaning before use. It was a work in progress.

Problems to be Solved by the Invention As described above, conventional optical information recording and reproducing devices have not been provided with cleaning means for removing dirt and dust or for removing generated static electricity. For this reason, there is a major problem in that the user cannot record and reproduce information satisfactorily unless he or she performs a complicated cleaning operation before using the device.

Means for Solving the Problems In order to solve the above problems, the present invention provides cleaning means for a card-shaped recording medium near the insertion opening of the main body of an optical information recording/reproducing apparatus.

Operation Since the optical information recording/reproducing device of the present invention has the above-mentioned cleaning means, even if a card-shaped recording medium with dirt or dust attached is used, the cleaning means can remove the dirt and dust inside the device. It is possible to take a peek. Thereby, the present optical information recording/reproducing apparatus can record, reproduce, and erase information in a good condition at all times.

Embodiment FIG. 1 is a perspective view showing an embodiment of the present invention. This figure shows a loading section for inserting a card-shaped recording medium into the main body of the apparatus. In addition to the loading section, this device includes a card transfer section that moves the inserted card-shaped recording medium in a linear reciprocating motion at high speed, and an optical head transfer section that moves the optical head that records, reproduces, and erases information to any position. , consists of the card transfer unit, the optical head transfer unit, a control circuit unit that controls the optical head, a circuit unit that processes electrical signals obtained from the optical head, etc., and randomly records and reproduces information on a card-shaped recording medium. Or it has a structure that can be erased. In FIG. 1, a card-shaped recording medium 4 is inserted into the device. The loading roller 1 is composed of an elastic rubber material portion 1a and a conductive and soft brush portion 1b made of carbon fiber or the like.
Moreover, the center portion is fixed to the support shaft 2. On the spindle 2,
It is rotatably fixed to the main body of the device, and one end is A.
It is fixed to a rotating drive body such as a C motor.

At the bottom of the loading roller 1, a loading roller 3 made of an elastic rubber material is fixed to a support shaft 2, and the support shaft 2 is rotatably fixed to the main body of the apparatus, and biasing means such as a plate spring material. , it is urged toward the upper loading roller 1. Said two loading rollers 1.3
At the rear, there is a fixing base 6 for fixing the card-shaped recording medium 4.
is provided. The fixed base 6 is supported by two guide shafts or the like so as to be capable of linear reciprocating motion, and is fixed to a driving body such as a linear motor. With the loading mechanism configured as described above, the card-shaped recording medium 4 can be loaded into two
When inserted between the loading rollers 1 and 3, it is held between the loading rollers 1 and 3 by the urging force of the lower loading roller 3, and is sent to the fixed table 6 as the loading roller 1 rotates. Next, the cleaning mechanism according to this embodiment will be explained using FIG. 2.

When the card-shaped recording medium 4 is inserted, the loading roller 1
The brush part 1b rotating in the same manner as above removes the foreign matter 6 attached to the card shape recording medium 4 while contacting the recording surface of the card shape recording medium 4. At this time, at the same time, All the static electricity charged on the medium 4 properly flows through the brush portion 1b to the ground line provided in the main body of the apparatus, and the static electricity is completely removed. Next, the foreign matter 6 enters the inside of a foreign matter storage case 7 attached to the rear of the loading roller 1. Inside the foreign object storage case,
A static electricity generating means 8 that generates static electricity by applying high pressure to a conductive metal is attached, and the device attracts the foreign object 6 that has entered the foreign object storage case 7 and removes the foreign object that has entered the foreign object storage case 7. 6 prevents it from going outside again. In the embodiments described above, a-
A cleaning guide is provided in a part of the cleaning roller 1.
By providing the brush portion 1b, the loading operation can be directly used for the cleaning operation, and the structure is very simple, and the space inside the apparatus can be used effectively. Further, the foreign matter 6 that is exposed through the eaves is attracted by the static electricity generating means 8, so that it does not float to the outside of the foreign matter storage case 7.

In this embodiment, the loading roller 1 and the cleaning brush portion 1b are integrated into a mechanism, but a cleaning brush may be provided separately.

Further, an exhaust pipe may be attached to the foreign matter storage case 7 to discharge accumulated dirt and dust to the outside of the apparatus.

Effects of the Invention As described above, according to the optical information recording/reproducing apparatus of the present invention, since the cleaning means is provided, the optical information recording medium can be cleaned, and proper recording, reproduction, erasing, etc. can be performed. I can do it. Furthermore, if a static electricity generating means for attracting dirt and dust is provided inside the foreign matter storage case as in the embodiment, the accumulated dirt and dust can be completely contained. Therefore, the influence of dirt, dust, etc. is further reduced, and information is always recorded stably.1. Reproduction and erasing can be performed, and the reliability of the device can be greatly improved. In addition, the user is freed from the conventional complicated leaning work.
