The gear train 80 includes a first gear 81 to a fourth gear 84, each of which is a two-stage gear. The first gear 81 meshes with the gear train 17 provided on the lower frame 11, and the fourth gear 84 is a double gear. When the loading prevention shutter 32 is in the open position, it engages with the transport gear 37. The second gear 82 meshes with the rack gears 72a and 73b when the link lever 72 and the shutter lever 73 move forward.

  A clamper 90 is disposed at the center of the upper frame 12. An iron plate is attached to the clamper 90. On the left and right sides of the clamper 90 are a pair of left and right left holding arms 91 that rotate between a holding position that holds the clamper 90 (see FIG. 12) and a holding release position that releases the holding (see FIG. 15), and a right holding arm. 92 is arranged.

  A pair of left and right left slide levers 93 and 94 that rotate the respective holding arms 91 and 92 are disposed behind the respective holding arms 91 and 92. Each slide lever 93, 94 is urged inward by a spring (not shown).

  Rack gears 93a and 94a are formed at the inner ends of the slide levers 93 and 94, respectively. The rack gear 93 a meshes with the left connecting gear 95, and the rack gear 94 a meshes with the right connecting gear 96. These connecting gears 95 and 96 are rotatably attached to the upper frame 12 and mesh with each other. The slide levers 93 and 94 are formed with pressing portions 93b and 94b that press and rotate the disk support arms 61 and 62, respectively.

  A cam protrusion 94 c formed at one end of the right slide lever 94 is inserted into a cam groove 74 a formed in the cam lever 74. The right slide lever 94 moves as the cam protrusion 94c moves along the cam groove 74a.

  Next, the operation of the above embodiment will be described. Before the insertion of the disk D1, as shown in FIG. 7, the double loading prevention shutter 32 and the sound insulation shutter 41 are set in the open positions for opening the slots 3a and 4a, thereby enabling the insertion of the disk D1. Yes.

  As shown in FIGS. 8 and 13, when the disk D1 is inserted from the slot 4a of the bezel 4, the disk D1 comes into contact with the disk detection portions 51a and 52a of the left and right disk detection arms 51 and 52, and the disk D1 is pushed in. Accordingly, the left disc detection arm 51 rotates counterclockwise in FIG. 13 about the shaft 53, and the right disc detection arm 52 rotates clockwise in FIG. 13 about the shaft 54.

  When the right disc detection arm 52 is rotated, the disc detection switch 18 is turned ON by the switch pressing lever. Based on the ON signal of the disk detection switch 18, the loading motor 16 rotates. The rotation of the loading motor 16 is transmitted to the conveyance gear 37 via the gear train 17 and the gear train 80, and the disk conveyance roller 31 of the double loading prevention shutter 32 rotates clockwise in FIG.

  When the disk D1 is inserted, the double loading prevention shutter 32 is rotated clockwise in FIG. 8, and the disk D1 is sandwiched between the disk guide 30 and the disk transport roller 31. Then, the disk D 1 is carried into the main body case 3 by the rotation of the disk transport roller 31. Even in this state, since there is a gap between the main body 32a and the first interlocking boss 41f, a disk thicker than the disk D1 is inserted, and the double loading prevention shutter 32 is further rotated from the position shown in FIG. Even in this case, the main body 32a does not contact the first interlocking boss 41f.

  When the disc D1 is carried in, as shown in FIG. 14, the rear end portion of the disc D1 comes into contact with the disc support portions 61a and 62a of the left and right disc support arms 61 and 62, and the left disc support arm 61 14 rotates counterclockwise in FIG. 14 and the right disc support arm 62 rotates clockwise in FIG.

  With further loading of the disk D1, the rear end of the disk D1 comes into contact with the disk contact part 67a of the link arm 67, and the link arm 67 rotates counterclockwise in FIG.

  When the disk D1 is loaded to the recording / reproducing position shown in FIG. 14, the pressing portion 67b of the link arm 67 presses the slide lever 71 and moves it forward. When the slide lever 71 moves forward, the link lever 72 is moved forward by being pressed by the slide lever 71, and the rack gear 72 a of the link lever 72 meshes with the second gear 82 of the gear train 80.

  When the rack gear 72a meshes with the second gear 82, the rotation of the loading motor 16 is transmitted to the link lever 72, and the link lever 72 moves forward. When the link lever 72 moves forward, the shutter lever 73 is pressed by the pressing portion 72 b of the link lever 72 and moves forward, and the rack gear 73 b meshes with the second gear 82. As a result, the shutter lever 73 moves forward by the rotation of the loading motor 16.

  As shown in FIG. 15, when the shutter lever 73 moves forward, the cam lever 74 coupled to the shutter lever 73 also moves forward. The right slide lever 94 moves outward along the cam groove 74a because the cam projection 94c is fitted in the cam groove 74a.

  When the right slide lever 94 moves outward, the right connecting gear 96 is rotated by the rack gear 94a of the right slide lever 94, and this rotation is transmitted to the rack gear 93a of the left slide lever 93 via the left connecting gear 95, and the left slide. The lever 93 also moves outward. By the movement of the slide levers 93 and 94, the left and right holding arms 91 and 92 are rotated to the holding release position, and the holding of the clamper 90 is released.

  Since an iron plate is attached to the clamper 90, when the holding is released, the clamper 90 is attracted by the magnet 24 provided on the clamp head 23. As a result, the clamp head 23 enters the center hole D1a of the disk D1, and the disk D1 is clamped between the clamp head 23 and the clamper 90 (see FIG. 9).

  At the same time as the holding of the clamper 90 is released, the left and right disc support arms 61 and 62 are pressed by the pressing portions 93b and 94b of the slide levers 93 and 94 to separate the left and right disc support arms 61 and 62 from the disc D1. Rotate in the direction. By this rotation, the link arm 67 is also separated from the disk D1. Thereby, at the time of disc clamping, the disc D1 is in a free state.

  Further, at the same time when the holding of the clamper 90 is released, as shown in FIG. 9, the shutter contact portion 73 a of the shutter lever 73 contacts the bearing 36 provided on the double loading prevention shutter 32, thereby The double loading prevention shutter 32 is rotated clockwise in FIG.

  When the double loading prevention shutter 32 is rotated, the disc transport roller 31 moves away from the disc D1, and then the main body 32a comes into contact with the first interlocking boss 41f of the sound insulation shutter 41. When the double loading prevention shutter 32 is further rotated from this state, as shown in FIG. 10, the main body 32a presses the first interlocking boss 41f of the sound insulation shutter 41, and the sound insulation shutter 41 is clockwise in FIG. To be rotated.

  As shown in FIG. 11, when the double loading prevention shutter 32 is rotated to the closed position, the sound insulating shutter 41 is also rotated to the closed position in conjunction with this, and is closely attached to the rubber 47, so that the entire range of the slot 4a is reached. Closed. When the sound insulating shutter 41 is located at the closed position, the sound insulating shutter 41 is biased toward the closed position by the left and right toggle springs 45 and 46.

  When the disk D1 is loaded in the main body case 3, the double loading prevention shutter 32 is rotated to the closed position, so that another disk is prevented from being loaded accidentally (for example, the sound insulation shutter 41). Even if an attempt is made to open another disc and load another disc, the double loading prevention shutter 32 prevents it).

  When the disk 3 is clamped and the slots 3a and 4a are closed by the shutters 32 and 41, the loading motor 16 is stopped and the spindle motor 21 is rotated. When the spindle motor 21 rotates, the disk D1 is rotated at a high speed by the turntable 22, the clamp head 23, and the clamper 90. During the high-speed rotation of the disk D1, the pickup head 28 moves in the radial direction of the disk D1, and information is recorded or reproduced. Noise is generated during the rotation of the disk D1, but it is reduced by the sound insulation shutter 41 and is prevented from leaking out of the slot 4a.

  Further, after the disk D1 is carried into the recording / reproducing position by the disk conveying roller 31 and the disk conveying roller 31 is separated from the disk D1, the main body 32a comes into contact with the first interlocking boss 41f and the sound insulating shutter 41 rotates. Be started. As a result, when the disk D1 is loaded, the disk transport roller 31 is not subjected to a load for rotating the sound insulation shutter 41, so that the disk D1 is reliably loaded.

  When the disk D1 loaded in the main body case 3 is carried out, a command from the information device is sent to the disk device 2. A control circuit (not shown) provided on the control circuit board 14 of the disk device 2 first stops the spindle motor 21 and then reverses the loading motor 16. Due to the reverse rotation of the loading motor 16, the shutter lever 73 moves backward. By this movement of the shutter lever 73, the double loading prevention shutter 32 is rotated counterclockwise in FIG.

  When the double loading prevention shutter 32 rotates, the main body 32a presses the second interlocking boss 41g of the sound insulation shutter 41, and the sound insulation shutter 41 is rotated counterclockwise in FIG. When the double loading prevention shutter 32 is rotated to the open position shown in FIG. 7, the sound insulation shutter 41 is also rotated to the open position in conjunction with this, and the slots 3a and 4a are opened. Further, the transport gear 37 meshes with the fourth gear 84, and the disk transport roller 31 rotates (reverses). When the sound insulation shutter 41 is in the open position, it is urged toward the open position by the left and right toggle springs 45 and 46.

  When the rearward movement of the shutter lever 73 is started, the cam lever 74 also moves rearward. In the right slide lever 94, since the cam protrusion 94c is fitted in the cam groove 74a, the right slide lever 94 moves inward along the cam groove 74a, and the left slide lever 93 also moves inward. As the slide levers 93 and 94 move, the left and right holding arms 91 and 92 rotate to the holding position, the clamper 90 is held, and the clamp of the disk D1 by the clamper 90 is released.

  After the clamp is released, the disk D1 is carried out to the eject position shown in FIG. When the disk D1 is unloaded to the eject position, the disk detection switch 18 is turned off and the output of the ON signal from the disk detection switch 18 is stopped. Based on the output stop of the ON signal, the rotation of the loading motor 16 is stopped.

  In the above embodiment, the disk transport roller 31 is attached to the double loading prevention shutter 32, but the double loading prevention shutter is omitted, and as shown in FIG. 16, the left roller support plate 101 and the right roller The disk transport roller 31 may be rotatably mounted between the support plate 102 and the support plate 102. In this case, an insertion rib 101a that is inserted between the first interlocking boss 41f and the second interlocking boss 41g of the sound insulating shutter 41 is formed on the left roller support plate 101. In this embodiment, the sound insulation shutter 41 achieves both functions of preventing sound leakage and preventing double loading of the disk D1.

  The disk transport roller may be omitted from the double loading prevention shutter. In this case, the sound insulation shutter rotates in conjunction with the double loading prevention shutter. A dedicated drive mechanism for rotating the sound insulation shutter may be provided.

  Furthermore, a hole for interlocking with the double loading prevention shutter may be formed in the sound insulation shutter, and a protrusion formed on the double loading prevention shutter may be inserted into this interlocking hole. Further, the sound insulation shutter may be fixed to the double loading prevention shutter.

  A disk device may be used in an environment where noise due to disk rotation is not noticeable. In such a disk device, since a sound insulation shutter is unnecessary, a bezel without a sound insulation shutter is attached to the main body case. In this way, two types of disk device with a sound insulation function and a disk device without a sound insulation function can be easily made, so that it is easy to change the model.
