Description

  The present invention relates to a disk storage type disk device in which a plurality of disks are stored inside a housing, and the disks are selected and driven.

  As a disk storage type disk device for in-vehicle use, etc., a drive unit having a rotation drive unit (turn table) is provided in one case, and a plurality of supports are provided in the case in a stacked manner. There is something that holds the disc in the body.

  In this type of disk storage type disk device, with the drive unit retracted to the outside of the outer peripheral edge of the disk supported by each support body, the support body is moved in the overlapping direction so that either support is performed. The body is moved to the selected position. After the support is selected, the drive unit is moved to an opposing position that overlaps the selected support.

  When the disc is inserted from the insertion port of the housing, the disc is supplied to the rotation drive portion of the drive unit at the opposite position by the conveying means, clamped by the rotation drive portion, and driven to rotate. Alternatively, the selected disk held on the support moved to the selected position is transferred to the rotation drive unit of the drive unit and clamped, and the disk is driven to rotate.

  The selected disk that has been rotationally driven by the drive unit is returned to the insertion slot of the housing by the conveying means. Alternatively, the selected disk that has been rotationally driven is delivered to the support at the selected position, and a plurality of disks are stored and held together with the support in the housing.

  In this type of disk storage type disk device, since the disk is held by a plurality of supports provided in the housing, for example, a drive mode in which the selected disk is rotationally driven by a drive unit or a housing is provided. In the standby mode in which the disc is inserted from the insertion slot, the discs held on the respective supports may move and rattle.

Therefore, in the disk device described in Patent Document 1 below, a restricting plate that presses a disk other than the selected disk clamped by the drive unit from the outer peripheral edge thereof is provided. When the drive unit moves to a drive position for rotationally driving the disk, the restriction plate is operated by the moving force of the drive unit, and the outer peripheral edge of the disk other than the selected disk is pressed by the restriction plate.
JP 2003-141809 A

  However, in the disk device described in Patent Document 1, since the outer peripheral edge of the disk is pressed by the restriction plate, an area in which the restriction plate moves is provided outside the outer peripheral edge of the stored disk in the housing. This makes it difficult to reduce the size and thickness of the device. Further, since bending stress acts on the disk whose outer peripheral edge is pushed by the restriction plate, it is not preferable in terms of deterioration of the disk quality.

  Further, since the disc device described in Patent Document 1 has a structure in which the regulating plate is operated by the moving force of the drive unit, the disc is pressed by the regulating plate only when the drive unit reaches the driving position for driving the disc. Therefore, it is difficult to design the disc so as not to move in a mode other than the drive mode for driving the disc.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object of the present invention is to provide a disk storage type disk device that can reliably regulate disks other than selected disks among the disks stored in a housing.

  Another object of the present invention is to provide a disk storage type disk device capable of restricting a disk in various modes other than a selection mode in which a disk is selected by moving a support.

The present invention provides a plurality of supports that can support a disk and are arranged in the thickness direction of the disk in a housing, support selection means for moving any one of the supports to a selected position, and support for the selected position. In a disk storage type disk device having a drive unit that clamps and rotates the selected disk supported by the body,
In the casing, a movable member that moves between a restricting member located in a central hole of a disc other than the selected disc, a pressure contact position protruding from the restricting member, and a retracted position retracting toward the restricting member. And a switching mechanism for moving the movable pressing portion between the press-contact position and the retracted position,
The movable pressing portion and the restricting member at the press-contact position are press-contacted to an inner peripheral edge of a central hole of a disc other than the selected disc.

  In the disc storage type disc device of the present invention, the central hole of the disc other than the selected disc is held from the inside by the movable pressing portion and the regulating member at the press contact position. Therefore, it is not necessary to arrange the regulating member and the mechanism for operating the regulating member outside the disk in the housing, and the space in the housing can be used effectively. Further, since the center hole of the disc is held, unnecessary bending stress does not act on the disc.

  For example, in the present invention, at least in the drive mode in which the selected disk is rotationally driven by the drive unit, the movable pressing portion is moved to the press contact position.

  Since the movement of the disks other than the selected disk can be restricted when the selected disk is driven to rotate, it is possible to prevent other disks from rattling due to vibration when the selected disk is driven.

  Alternatively, the present invention can be configured such that the movable pressing portion is moved to the press contact position in at least the standby mode in which the introduction of the disk into the housing is on standby.

  With this configuration, it is possible to prevent the disk from rattling even in the standby mode even if vehicle body vibration or the like acts.

  Further, the present invention provides an elastic structure in which the movable pressing portion is brought into pressure contact with the inner peripheral edge via an elastic force at least one of a power transmission path of the switching mechanism and a press contact portion between the movable pressing portion and the inner peripheral edge. It is preferable that a member is provided.

  When the movable pressing portion is pressed against the center hole of the disk via an elastic force, an excessive pressure contact force does not act on the center hole of the disk, and the shape of the center hole of the disk can be easily maintained in a normal state.

  Further, according to the present invention, the restricting member is provided with a movable restricting portion that protrudes in the moving direction of the support, and in the selection mode in which the support is selected by the support selecting means, The movable restricting portion located in the center hole of the selected disc after the center holes of all the supported discs move along the outer peripheries of the restricting member and the movable restricting portion and the selected disc stops at the selected position. However, it retreats toward the regulating member.

  For example, the movable pressing portion and the movable restricting portion are operated synchronously by the switching mechanism, and the movable restricting portion retracts toward the restricting member when the movable pressing portion moves to the press contact position. When the movable pressing portion moves to the retracted position, the movable restricting portion protrudes from the restricting member.

  Since the movable pressing portion and the movable restricting portion are driven synchronously by the same switching mechanism, the configuration of the switching mechanism can be simplified. Also, since the movable pressing portion is in the pressure contact position when the movable restricting portion protrudes and the support is selectively moved, the structure can be configured to restrict the disc in all modes other than the selection mode. It is.

  In the disk storage type disk device of the present invention, disks other than the selected disk can be securely held, and the arrangement space of the mechanism for holding the disk can be reduced. Furthermore, it is possible to hold the center hole of the disk in conjunction with the operation of the movable restricting portion protruding from the restricting member.
