Description

The invention relates to the field of storage of information on compact discs and can be used to clean an element located in the internal cavity of a device for reading information from compact discs, namely, a spindle bed on which compact discs are mounted.

A device is known for cleaning an optical head for reading information from CDs, containing a cleaning CD, on the surface of which there is a protrusion on the side of the optical head, which creates an air stream during rotation of the CD, US 5088083. This stream blows off dust particles remaining on the optical the head after its contact with the mechanical cleaning element; an insignificant part of the dust is blown out of the internal cavity of the device, and the main part of it again settles.

A device for cleaning the internal cavity of a device for reading information from compact discs is provided, comprising a cleaning CD that can be rotated in this cavity, equipped with an electrically cleaning CD element electrically cleaning the CD, rubbing against the surface of the CD when rotating the latter; an element of dielectric material may be installed on the surface of the cleaning compact disc in the contact zone with its electrifying element; at least one conductive element may be placed on the surface of the cleaning CD; this element in the presence of an element of dielectric material is in contact with it; the conductive element can be connected to the housing of the device for reading information from CDs, RU 2239883 C1.

The device allows you to collect dust in the cavity of the device for reading information, and to evacuate its main part; to a small extent, this device allows you to clean and located in the specified cavity of the spindle lodgement.

Its disadvantage is the fact that the device, based on the electrostatic principle, poorly removes dirt from the surface of the spindle bed, closed during cleaning by the cleaning disk. Contaminations remaining on the surface cause the CDs to skew, lose focus on the reading lens, and malfunction when reading (writing) information.

A device for cleaning the lodgement of the spindle of a device for reading and / or writing information to compact discs, including a housing and a loading module. It contains a cleaning element, which is located on a special cleaning CD, installed in the internal cavity of the device for reading and / or recording information on the spindle bed of this device; the cleaning element is made in the form of grooves or brushes, RU 2334280 C1.

This technical solution is taken as a prototype of both variants of the present invention.

The disadvantage of the prototype is the need for a cleaning device (CD), separate from the reader and / or write information. In the absence of this separate device, the spindle tool tray does not clean. At the same time, the cleaning performed using the prototype device requires an additional procedure to the reading / writing of information, which complicates the operation of the reading / writing device. The need for the next cleaning of the spindle tool tray is detected only when reading / writing information fails, which when reading information can lead to malfunctioning of operating systems, and when writing information - to loss of information, as well as to failure of CDs, which are recorded.

The objective of both variants of the present invention is to simplify operation by including the cleaning process of the spindle lodgement in the operating cycle of the device for reading / writing information, as well as improving the quality of reading / writing information by ensuring the independence of the cleaning process from operator actions.

According to a first embodiment of the invention, in a device for cleaning a spindle bed of a device for reading and / or writing information to CDs, comprising a housing and a loading module comprising a cleaning element, the cleaning element is located on the loading module or housing of the reader and / or information recording device and is equipped with means bringing it into contact with the cleaned surface of the spindle bed when cleaning it; the cleaning element is made in the form of a balancer mounted on the loading module by means of a hinge, while the free end of the balancer on the side of the spindle lodgement is equipped with a brush or scraper, and the means for bringing the cleaning element into contact with the surface of the spindle lodgement is made in the form of a spring; the cleaning element can be made in the form of a rotary console attached to the housing, while the free end of the console on the side of the spindle lodgement is equipped with a brush or scraper.

According to a second embodiment of the invention, in a device for reading and / or writing information to a compact disc including a housing and a loading module comprising a cleaning element, the cleaning element is made in the form of a console made integral with or attached to the loading module, the free end of the console having side of the spindle tool tray is provided with a brush or scraper.

The applicant has not identified any technical solutions identical to the variants of the claimed invention, which allows us to conclude that the invention meets the criterion of "Novelty."

The implementation of the distinguishing features of one or the other variant of the invention leads to important new properties of the object. First of all, it eliminates the need for a separate device (a special CD-ROM) for cleaning the spindle lodgement of the reader / writer device. All operations with the insertion of this CD, the implementation of cleaning with it and its removal upon completion of this process are accordingly excluded. In addition, it is very important that the spindle lodgement is cleaned periodically during the operation of the information reader / writer, and not at the request of the operator after it detects a need for such cleaning, which occurs, as a rule, when reading / writing information fails. This eliminates the malfunctioning of operating systems when recording information and the loss of information, as well as the failure of CDs during recording.

The applicant has not identified sources of information that would contain information about the influence of the distinguishing features of the variants of the invention on the achieved technical result. These new properties of the object determine, according to the applicant, the compliance of the invention with the criterion of "Inventive step".
