  The restricting means described in Patent Document 1 has a structure in which the restricting arm portion is directly rotated by the advancing and retracting member that moves forward and backward within the lower restricting member. On the other hand, the restricting arm portion needs to be rotated by approximately 90 degrees from a retracted posture in which the disc is in the selected position so as not to interfere with the restricting posture connecting the lower restricting member and the upper restricting member. For this purpose, it is necessary to move the advancing / retracting member that rotates the restricting arm part in the lower restricting member for a long distance in the vertical direction.

  For this reason, the lower restriction member is longer in the vertical direction than necessary, but the gap between the lower restriction member and the upper restriction member needs to be set to be somewhat long. As a result, the lower restriction member and the upper restriction member Longitudinal dimensions occupied by the hinder the thinning of the equipment.

  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 in which a restricting means for preventing a disk moving by a selection operation from being detached from a disk holder can be formed thin. .

  The disk storage type disk apparatus of the present invention has a structure in which a rotating member is rotated by an advancing / retracting member, and a regulating body is rotated by the rotating member. Since the distance from the turning fulcrum to the connecting fulcrum with the regulating body is longer than the distance from the turning fulcrum of the turning member to the acting point of the force that operates the turning member with the advance / retreat member, the turning member is Then, the advance / retreat operation of the advance / retreat member is amplified and transmitted to the regulating body. Therefore, even if the advance / retreat operation distance of the advance / retreat member is short, the restricting member can be largely rotated from the retracted position to the restricting position. Therefore, the length of the base of the disk regulating mechanism can be shortened, which can contribute to the thinning of the apparatus.

When the link arms 104, 104 rotate in the α1 direction shown in the figure, the connecting fulcrum shaft 107A enters the interlocking space 105d. When the link arms 104 and 104 are further rotated in the α1 direction shown in the figure, the connecting fulcrum shaft 107A presses the short convex portion 105b1 surrounding the interlocking space 105d upward as shown in FIG. 11B. As a result, the rotational force of the link arms 104, 104 acts on the restricting body 105 from the connecting fulcrum shaft 107A, and the restricting body 105 rises from the substantially horizontal retracted posture shown in FIGS. 3 (B) and 11 (A). To the restriction posture shown in FIG. 3 (A) and FIG.

  Here, when the restricting body 105 is in the retracted position, as shown in FIG. 11A, the connecting fulcrum shaft 107A provided on the link arms 104, 104 is connected to the end of the connecting elongated hole 105b formed in the restricting body 105. The restricting body 105 is held so as not to move in the retracted posture. When the link arms 104, 104 are rotated in the α1 direction shown in the figure, the connecting fulcrum shaft 107A moves into the interlocking space 105d as shown in FIG. 11B, and the link arms 104, 104 are further rotated in the α1 direction shown in the drawing. When it moves, as shown in FIG. 12, the regulating body 105 stands up in the regulating posture. At this time, the connection fulcrum shaft 107A enters the connection elongated hole 105b again, and presses the end of the connection elongated hole 105b. The restricting body 105 that has received this pressing force is pressed against the inner peripheral surface of the cylindrical opposing restricting member 111 as shown in FIG. 4A, and the restricting body 105 is held so as not to move in the restricted posture. .

  As described above, when the drive unit 14 moves to the retracted position, as shown in FIG. 3A, the restricting body 105 is positioned between the cylindrical body 101B of the base body 101 and the lower end 111a of the opposing restriction member 111. To come. Therefore, in the selection operation of the support body 21, when each support body 21 moves in the Z1-Z2 direction shown in the figure, the center hole D1 of the disk D held by the support body 21 is always restricted, and the disk D is supported. It can prevent coming off from the body 21.

  Next, one of the supports 21 is moved to the selected position shown in FIGS. 3A and 3B, that is, into the gap between the cylindrical body 101B and the opposing regulating member 111, and is supported by the support 21 at the selected position. When driving the disk D, the rack member 30 of the first switching mechanism 12 shown in FIG. 1 is moved in the Y1 direction. The drive unit 14 is rotated in the direction shown in FIG. 2A by the drive pin 33 provided on the switching slider 34 that moves in the Y1 direction together with the rack member 30 to reach the drive position shown in FIG.

  At this time, since the intermediate slider 31 shown in FIG. 10 moves together with the switching slider 34 in the Y1 direction, the switching link 110 is rotated in the β3 direction by the switching pin 31a of the intermediate slider 31, and the drive slider 109 is further moved. It is moved in the direction shown in FIG. Therefore, as shown in FIG. 8, the rotation drive member 102 is rotated in the β2 direction by the rack portion 109a, the sliding convex portion 103c is lowered in the Z1 direction by the cam groove 102a, and the advance / retreat member 103 is moved. Be lowered. At this time, the link arms 104 and 104 rotate in the β1 direction shown in FIG. 11A through FIG. 12B to FIG. 11B, and the regulating body 105 rotates toward the retracted posture. Be made.

  As a result, as shown in FIG. 3B, a space is formed between the disk D supported by the support 21 at the selected position and the restricting body 105 in the retracted posture, and the drive unit is directed into this space. 14 turntables 82 can intervene.

  As shown in FIGS. 4, 8, and 9, an action shaft 103 b that is an action point of force from the advance / retreat member 103 to the link arm 104 from the axis of the rotation fulcrum shaft 107 </ b> B that is the rotation fulcrum of the link arm 104. The distance from the rotation fulcrum to the axis of the connection fulcrum shaft 107A, which is the connection fulcrum between the link arm 104 and the restricting body 105, is longer than the distance to the axis. Therefore, the raising / lowering operation of the advance / retreat member 103 is amplified and acts on the restricting body 105, and even if the advance / retreat movement distance of the advance / retreat member 103 is short, the restricting posture where the restricting body 105 stands up vertically from a substantially horizontal restricting posture. It is possible to rotate it largely (approximately 90 degrees).

  Further, as shown in FIGS. 11A and 11B and FIG. 12, the distance from the axis of the support shaft 108, which is the rotation fulcrum of the regulating body 105, to the axis of the connection fulcrum shaft 107A is It is always shorter than the distance from the shaft center to the shaft center of the action shaft 103b. Therefore, even if the rotation angle of the connecting fulcrum shaft 107A is small, a large rotation angle of the restricting body 105 can be ensured.

  As described above, the elevation distance of the advancing / retreating member 103 can be shortened, and the rotation angle of the connecting fulcrum shaft 107A can be reduced. Therefore, the height dimension of the disc restricting mechanism 100 can be shortened, and as a result, it can contribute to thinning of the device. Become.

  In this embodiment, the first switching mechanism 12 performs both the switching operation for moving the drive unit 14 to the retracted position and the switching operation for raising the regulating body 105 to the regulated posture. And the operation of the disk restricting mechanism 100 can be synchronized. For example, when the drive unit 14 is rotated to the drive position, the restrictor 105 cannot be rotated to the retracted position, and the drive unit 14 and the restrictor 105 are Inconveniences such as hitting can be avoided.

  In contrast to the above-described embodiment, a structure may be employed in which an interlocking space 105d is formed in the link arm 104 that is a rotating member, and the connecting fulcrum shaft 107A is fixed to the restricting body 105.
