Embodiment Construction

[0021] Figures 1 to 3 Shown is a main part of a recording and / or reproducing apparatus for recording and / or reproducing information on and / or from an optical recording medium, such as a CD, a CD-ROM, or the like. In a housing (not shown) of the recording and / or reproducing apparatus, there is a drive board 1 on which various mechanical and electronic components for recording information on and / or reproducing information from an optical recording medium are arranged. 1 on the driver board.

[0022] exist Figures 1 to 3 In particular, a turntable 11 for holding an optical recording medium is shown, which turntable 11 can be driven in rotation via a rotating shaft 14 by a suitable drive mechanism (not shown). Also provided on the driver board 1 is an optical head 9 which is arranged in a suitable housing 4, which itself is shown in FIGS. 4A and 4B and which in particular has an objective or lens System 7. The objective lens 7 is used to align the light beam with the optical...

Abstract

A protective cover for an objective of an optical head is proposed which can be moved between a position covering the objective and a position exposing the objective. In the position exposing the objective, the protective cover is positioned outside the plane between the optical head and an optical recording medium located opposite the optical head.

Description

technical field [0001] The invention relates to a protective cover for an objective lens of an optical head of a recording and / or reproducing device according to the preamble of claim 1; the invention also relates to a recording and / or reproducing device using the protective cover or reproduction device; and the use of the protective cover during the manufacture and / or transportation of the optical head. Background technique [0002] The optical head of a recording and / or reproducing device for an optical recording medium, especially its objective lens is a sensitive part, which must be protected during the manufacture and transportation of the optical head, even when installed in a recording and / or reproducing device should also be protected. In particular, in order to guarantee their usability, protection against dust, fingerprints, mechanical damage, etc. is required. [0003] Thus, for example known optical heads are provided during manufacture and shipping with eg Fi...
