However, since the support moved to the selected position does not have another support at the upper and lower approach positions, the support at the selected position cannot be constrained by the other support. Therefore, when the disc held on the support at the selected position is transferred to the turntable and rotated, the support remaining at the selected position is likely to generate rattling noise.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and disc storage that can prevent a support that is stopped at a selected position from rattling due to external vibration when the disc is held by a rotary drive unit. An object of the present invention is to provide a type disk device.

A disc storage type disc device according to the present invention is capable of supporting a disc in a housing, and a plurality of supports arranged to be stacked in the thickness direction of the disc, and a holding member for holding the disc between the supports And a support selection means for moving one of the supports to the selected position, a switching drive member for moving the holding member to the holding release position when the support moves to the selected position, and the holding member holding A drive unit having a rotation drive unit that moves to the release position and holds the center hole of the disc separated from the support at the selected position; and
A pressing part that is operated together with the switching drive member is provided, and when the holding member moves to the holding release position, the pressing part is moved to a position that presses the support at the selected position, When the holding member moves to a holding position for holding the disc with the support, the pressing portion is moved to a position that does not come into contact with the support at the selected position.

  In the present invention, the holding member provided on the support moved to the selected position moves to the hold release position, and the disk held on the support stopped at the selected position is separated and received by the rotation drive unit. When being passed, the support in the selected position is pressed by the pressing portion. Therefore, it is easy to prevent the support remaining at the selected position from rattling due to external vibration when the disk is driven to rotate. Further, when the holding member moves to the holding position and the disc is held between the support and the holding member, the pressing portion is retreated to a position where it does not hit the support, so the disc is held. When the support moves in the thickness direction, the pressing portion does not prevent the movement.

  According to the present invention, each support body is provided with the holding member and a biasing member that biases the holding member to the holding position, and the switching drive member is provided in the housing, and the support member moves to the selection position. The holding member provided on the support is moved to the holding release position by the moving force of the switching drive member.

  Since the switching drive member faces only the support at the selected position, only the support at the selected position is pressed by the pressing portion. Therefore, it can prevent that the support body other than a selection position receives unnecessary restraint by a press part.

  For example, in the present invention, the pressing portion is provided integrally with the switching drive member.

  That is, the pressing portion is integrally formed of the same material as that of the switching drive member, or the pressing portion is constituted by a part attached to the switching drive member. Alternatively, when the switching drive member operates, a member that is driven separately from the switching drive member by its power may be provided, and the pressing portion may be provided on this member.

  In the present invention, the pressing portion has an inclined portion that is inclined with respect to the support at the selected position, and the support at the selected position is suppressed from above by the inclined portion.

  When the support is pressed by the inclined portion provided in the pressing portion, the support can eliminate backlash in both the surface direction and the thickness direction, and can effectively prevent the support from rattling.

  In the disk storage type disk device of the present invention, it is possible to prevent the support remaining at the selected position from shaking when the disk is separated from the support at the selected position.

Next, the operation of the disk storage disk device 1 will be described.
(Disc loading operation)
When the operation unit or the remote controller provided on the front surface 7 of the housing 2 is operated and an operation for designating any one of the supports is performed, the power of the motor provided in the second power transmission unit 16 is 3, and the selection shafts 151 </ b> A, 151 </ b> B, 151 </ b> C are rotated synchronously by the transmission gear 99. The support body 21 is moved in the Z1-Z2 direction by the spiral selection groove 152 formed on each of the selection shafts 151A, 151B, 151C, and the designated support body 21 not holding the disk D is moved to the selection position. Be made.

  When the designated support 21 is moved to the selected position by the above operation, the power from the motor of the second power transmission unit 16 to the transmission gear 99 is cut off, and the rotation of the selection shafts 151A, 151B, 151C is stopped. Therefore, the designated support body 21 stops at the selected position.

  The support 21 is in the selected position when moved to the coarse pitch portion in the middle of the selection groove 152, but the support bodies 21 other than the support 21 in the selection position are the dense pitch portion on the lower side of the selection groove 152 or the upper side. It is located in the dense pitch part.

  The plurality of supports 21 positioned in the dense pitch portion on the upper side of the selection groove 152 are stopped at short intervals in the vertical direction. At this time, the upper restricting member 525 shown in FIG. 3 is inserted into the center hole Da of the disk D held by the respective support bodies 21 positioned in the upper dense pitch portion, and the disk is moved from each support body 21 to the disk. D is prevented from escaping.

  Moreover, in the support body 21 located in the upper dense pitch portion, the first support piece 211 shown in FIG. 2 (B) presses the disk D provided on the lower surface of the support body 21 located thereon from below. The second support piece 212 presses the disk D positioned thereon from below. Therefore, the support 21 located in the upper dense pitch portion and the disk D held by the support 21 are less likely to be rattled due to external vibration or the like.

  The same applies to the support 21 that is overlapped at a short distance in the lower position in the housing by the dense pitch portion below the selection groove 152.

  When the designated support member 21 stops at the selected position, the switching pressing portion 403b provided on the first holding switching member 403 faces the driving recess 27g of the holding member 27 as shown in FIG. However, since the first holding switching member 403 is moved in the Y1 direction, no pressing force is applied to the driving recess 27g from the switching pressing portion 403b, and the holding member 27 is moved in the γ2 direction by the tension coil spring 26a. It is rotated. Further, the switching pressing portions 505b and 505c of the second holding switching member 505 are opposed to the driving concave portion 28g of the holding member 28 and the driving concave portion 29g of the holding member 29, but the second holding switching member 505 is in the X2 direction. Therefore, no pressing force acts on the drive recess 28g and the drive recess 29g. Accordingly, the holding member 28 and the holding member 29 are rotated in the γ4 direction by the tension coil springs 26b and 26c, respectively. Therefore, the support 21 moved to the selected position can hold the disk D between its lower surface and the holding claws 27a, 28a, 29a.

  Further, immediately after the support 21 is stopped at the selected position, the first switching drive member 511 is moved and stopped in the Y1 direction, so that as shown in FIGS. 5, 6, and 7 (A), The pressing portion 530 provided in the first switching drive member 511 faces the concave portion 21d on the Y1 side of the left edge portion 21b of the support body 21, and the pressing force is applied from the pressing portion 530 to the support body 21 at the selected position. Is not working. That is, when the support body 21 is selected, the support body 21 moves in the Z1-Z2 direction, but the pressing portion 530 does not prevent the movement.

  When the designated support body 21 stops at the selected position, the first power transmission unit 12 shown in FIG. 1 operates, and the rack member 32 moves in the Y1 direction. The force at this time causes the drive unit 14 to move to FIG. 5 to the intervention position shown in FIGS. 5 and 6.
