The pickup device is configured to perform writing and/or reading of information with respect to an optical disc. The guide shaft is configured to movably support said pickup device. The fixing base member is attached to the chassis and configured to fasten one end of the guide shaft. The holding member is attached to the chassis, and includes a receiving chamber in which a corresponding end of the guide shaft. The elastically deformable member for resiliently pressing a corresponding end of said guide shaft in said receiving chamber includes a pressing portion above the receiving chamber of the holding member and a fixing portion engageable with the holding member for attaching the deformable member to the holding member. ## Claims ### Claim 1 An optical disc apparatus comprising: a chassis; a pickup device configured to perform writing and/or reading of information with respect to an optical disc; a guide shaft configured to movably support said pickup device; a fixing base member attached to said chassis and configured to fasten one end of said guide shaft; a holding member attached to said chassis, said holding member including a receiving chamber in which a corresponding end of said guide shaft is positioned; and an elastically deformable member for resiliently pressing a corresponding end of said guide shaft in said receiving chamber, said deformable member including a pressing portion above said receiving chamber of said holding member and a fixing portion engageable with said holding member for detachably attaching said deformable member to said holding member; wherein said holding member further includes a receiving portion aligned with the receiving chamber, said fixing portion of said deformable member is received in said receiving portion. ### Claim 2 (depends on 1) The optical disc apparatus in accordance with claim 1, wherein said receiving portion includes a proximal wall next to said receiving chamber, and a distal wall opposite to said proximal wall, and said fixing portion of said deformable member includes two contact portions elastically contacting with said distal wall and proximal wall of said receiving portion respectively. ### Claim 3 (depends on 2) The optical disc apparatus in accordance with claim 2, wherein said receiving portion further includes two opposite side walls and at least one slot adjacent to said proximal wall, said fixing portion of said deformable member further includes at least one protrusion received in the slot of said holding member. ### Claim 4 (depends on 2) The optical disc apparatus in accordance with claim 2, wherein said receiving portion further includes a top wall partly covering said receiving portion for limiting said fixing portion of said deformable member in said receiving portion of said holding member. ### Claim 5 (depends on 4) The optical disc apparatus in accordance with claim 4, wherein said fixing portion of said deformable member further includes a horizontal contact portion for abutting said top wall of said holding member. ### Claim 6 (depends on 1) The optical disc apparatus in accordance with claim 1, wherein said deformable member is a bent metal sheet. ### Claim 7 An apparatus for supporting an end of a guide shaft above a chassis, said apparatus comprising: a holding member adapted to be attached to said chassis, said holding member including a first receiving portion in which the end of the guide shaft is inserted, and a second receiving portion adjacent to said first receiving portion; and an elastically deformable member for resiliently pressing the end of the guide shaft, said deformable member including a pressing portion above said first receiving portion of said holding member and a fixing portion engageably received in said second receiving portion of said holding member for attaching said deformable member to said holding member. ### Claim 8 (depends on 7) The apparatus in accordance with claim 7, wherein said second receiving portion of said holding member includes two opposite walls, and said fixing portion of said deformable member includes two opposite contact parts respectively contacting said two opposite walls of said holding member. ### Claim 9 (depends on 7) The apparatus in accordance with claim 7, wherein said second receiving portion of said holding member includes at least one slot, and said fixing portion of said deformable member includes at least one protrusion inserted in the slot of said holding member. ### Claim 10 (depends on 7) The apparatus in accordance with claim 7, further comprising an adjusting screw inserted through the chassis into said first receiving portion for adjusting a location of the end of the guide shaft. ### Claim 11 An optical disc apparatus comprising: means for supporting optical discs in said optical disc apparatus; an optical pickup device movably installable beside said means in said optical disc apparatus for retrieving information from said optical discs; and a feeding mechanism for supportively positioning said optical pickup device and guiding movement of said optical pickup device in said optical disc apparatus, said feeding mechanism comprising a chassis disposed beside said means, at least one guide shaft abutting against said optical pickup device so as to allow said optical pickup device guidably movable along said at least one guide shaft while retrieving said information from said optical discs, and at least one holding member attachable to said chassis and capable of accommodating an end of said at least one guide shaft therein, a physically separate, elastically deformable member engageably extending against said at least one holding member for fixedly residing in said at least one holding member and engageably extending against said end of said at least one guide shaft in said at least one holding member so as to contribute to adjustably positioning of said at least one guide shaft relative to said chassis of said feeding mechanism. ### Claim 12 (depends on 11) The optical disc apparatus in accordance with claim 11, further comprising an adjusting screw extending into said at least one holding member engageably against said end of said at least one guide shaft so as to contribute to said adjustably positioning of said at least one guide shaft in cooperation with said elastically deformable member. ### Claim 13 (depends on 11) The optical disc apparatus in accordance with claim 11, wherein said at least one holding member is integrally formed with said chassis.
