3,134,135A, 135B, 135C, 135D
This increases the strength of the lid 130. Note that the diaphragm portion 135A and the diaphragm portion 135C, or the diaphragm portion 135B and the diaphragm portion 135D may be one continuous diaphragm, but the strength of the lid 130 can be further increased by dividing the diaphragm into a plurality of diaphragms.

Next, the bezel will be described with reference to FIGS. 3 and 4. The bezel 140 is provided with an insertion opening 141, and the insertion opening 141 is formed such that the central portion has the largest width and the width decreases toward both ends. A felt 142 having a notch is attached to the surface of the bezel 140 on the chassis exterior side along the insertion opening 141. As shown in FIG. 4, the felt 142 is bent in the traveling direction of the disc when the disc is loaded from the insertion port 141 or ejected from the insertion port 141. At this time, when the disc is mounted, the disc can be mounted by pushing it in even if there is some resistance, and it is preferable that the insertion opening 141 is narrow and the felt 142 further regulates the position for positioning the disc. However, when ejecting the disc, the felt 142
When the felt 142 bends and becomes parallel to the insertion opening 141, the frictional force between the disk and the surface of the felt 142 becomes extremely large and the disk is not ejected. Will occur. Therefore, in order to prevent troubles when the disc is ejected, the felt 14
It is preferable that the resistance due to 2 is small. So bezel 1

It is preferable that the area of the insertion port 141 on the inner side surface of 0 is wide. In the case of this embodiment in which the width of the insertion opening 141 on the outer side surface of the bezel 140 is narrower than the central portion at both ends, the width of both ends of the insertion opening 141 on the inner side surface of the bezel 140 is smaller. It is preferable that the outer surface of the bezel 140 is formed wider than both ends of the insertion opening 141. Further, the width of the insertion opening 141 on the outer side surface of the bezel 140 is wider than the disc thickness,
It is preferable that the thickness is made narrower than the thickness obtained by adding the felt thickness to the disc thickness, and the width of the insertion opening 141 on the inner side surface of the bezel 140 is formed wider than the thickness obtained by adding the felt thickness to the disc thickness. .

Next, the protect mechanism 120 shown in FIG. 1 will be described with reference to FIGS. 5 and 6. FIG. 5 is a front view of a main part of the protect mechanism according to this embodiment, and FIG. 6 is a side view of the main part of the protect mechanism. Protect mechanism 1
20 is a disc blocking lever 121 and a guide member 122.
Composed of and. A rotary shaft 123 for operating the disc blocking lever 121 is provided at one end of the disc blocking lever 121. Also, the disc blocking lever 12
A guide member 122 is provided on the other end side of the rotary shaft 1 by a rotary shaft 124. Also, the disc blocking lever 121
The end portion on the other end side is formed such that the width on the rotating shaft 123 side is narrower than the width on the tip end side. That is, as shown in FIG. 5, the side portion (left side in the drawing) far from the rotating shaft 123 has the tip end side (upper side in the drawing) outside the rotation shaft 123 side (lower side in the drawing) (left side in the drawing). The rotating shaft 12
The side portion (right side in the drawing) close to 3 has a shape in which the tip side (upper side in the drawing) is extended outward (right side in the drawing) than the rotation shaft 123 side (lower side in the drawing). Here, in a side portion (right side in the drawing) near the rotation shaft 123, a turning radius with the turning shaft 123 as a turning center has a tip end side (upper side in the drawing) on the rotation shaft 123 side (lower side in the drawing). It is formed to be smaller than The guide member 122 is pivotally supported on the base 126 by a rotation fulcrum 125 so as to be rotated by the operation of the disc blocking lever 121. The base 126 is fixed to the base body 10. As shown, when the disc 1C is mounted, the disc blocking lever 121
The other end side of the rotary shaft 123 is rotated about the rotary shaft 123 to a position where the insertion port 141 is closed. Therefore, even if another disc 1 is to be inserted, the disc blocking lever 121 prevents the insertion. Further, even if a load is applied to the disc blocking lever 121 by pushing the disc 1 forcibly, the guide member 122 causes the disc blocking lever 12 to move.
1 cannot be pushed and bent. Therefore, the disc blocking lever 1 due to the disc 1 being forced in is pushed.
Since the deformation of 21 can be prevented, the disk blocking lever 12
The operating space of 1 can be set narrowly. Further, it is possible to effectively use the limited space without providing a structure in which the disc blocking lever 121 has a thickness in the disc insertion direction to increase the strength of the disc blocking lever 121 itself.
Further, since the end of the other end of the disc blocking lever 121 is narrowed on the side of the rotating shaft 123, when the end comes into contact with the disc, the force from the disc causes the end to push toward the tip. To work. Therefore, when the disc is inserted, no force acts on the disc blocking lever 121 in the retracting direction, so that the disc can be reliably blocked from being inserted.

The movement of each member when the disc is inserted will be described below with reference to FIGS. 7 to 13. Figure 7
FIG. 3 is a plan view of the base body of the disc device showing an initial stage when the disc is inserted, which is a state of the disc 1A shown in FIG. 2. It should be noted that the pull-in lever 80 in a state where the disc 1 is not inserted stands by while being rotated by a predetermined angle toward the spindle motor 31 side. In this state, the convex portion 91 of the sub-lever 90 has the long groove 8 that does not reach the groove 83A.
It is located at the movable end of No. 3. The distance between the guide 17 and the second disc guide 81 is smaller than the diameter of the disc 1. At the initial stage when the disc 1 is inserted, the disc 1A first comes into contact with the guide 17 and the second disc guide 81, is supported by the guide 17 and the second disc guide 81, and the position is regulated. Disk 1
When A is further pushed in, the second disc guide 81 pivots in the direction away from the spindle motor 31 with this insertion action. This second disc guide 81
With the swiveling operation of, the convex portion 91 of the sub-lever 90 slides in the long groove 83 toward the fixed side end portion. Therefore, the sub-lever 90 also turns around the turning fulcrum. When the insertion operation of the disc 1A is further continued, the disc 1A contacts the guide 101 of the ejection lever 100. FIG. 7 illustrates this state. Note that in the state shown in FIG. 7, the loading motor 60 does not operate, and therefore the main slider 4
Neither 0 nor the sub lever 50 operates.

FIG. 8 is a plan view of the base body of the disc device showing the stage of inserting the disc, showing the state of the disc 1B shown in FIG. When the disc 1 is further inserted from the state shown in FIG. 7, one end side of the disc is supported by the guide 17 and the other end side is supported by the third disc guide 84. The pull-in lever 80 is the spindle motor 31.
Is most distant from. In this state, the convex portion 91 of the sub-lever 90 is located at the fixed side end portion of the long groove 83. The distance between the guide 17 and the second disc guide 81 is approximately the same as the diameter of the disc 1. On the other hand, since the guide 101 is pushed by the disc 1B, the ejection lever 100 continues to rotate as the disc is inserted. When the disc 1B is further pushed in from the state of FIG. 8, the second disc guide 81 moves in the direction of approaching the spindle motor 31 this time with this inserting operation. As the second disc guide 81 pivots, the convex portion 91 of the sub-lever 90 moves into the long groove 83.
The inside slides from the fixed end to the movable end. Therefore, the sub-lever 90 also turns around the turning fulcrum 92. On the other hand, in the above operation process, the disc 1B contacts the guide 112 of the regulation lever 110, and the regulation lever 1
10 rotates. When the second disc guide 81 rotates by a predetermined angle in the direction of approaching the spindle motor 31, the regulating lever 110 also rotates by a predetermined angle by the disc 1B. Then, when the restriction lever 110 rotates by a predetermined angle, the limit switch operates, and the loading motor 60 starts driving. The guide lever 18
The guide 182 of 0 is in a state of protruding toward the disc 1B side, and the disc 1B is supported by the guide 182 and slides. By driving the loading motor 60, the main slider 40 starts sliding on the rear surface side. Then, by the operation of the main slider 40, the pin 93 of the sub-lever 90 moves along the cam groove provided in the corresponding main slider 40. At this time,
The pin 93 moves to the spindle motor 31 side by the corresponding cam groove. The movement of the pin 93 causes the sub-lever 90 to urge the pull-in lever 80 in the direction in which the movable side end of the pull-in lever 80 pivots to the spindle motor 31 side.
Therefore, the pull-in lever 80 urges the disc 1B in the inserting direction. Due to the urging force of the pull-in lever 80, the disc is pushed further out of the manual operation.

FIG. 9 is a plan view of the base body of the disc device showing the stage where the disc insertion is completed, showing the state of the disc 1C shown in FIG. The disc 1C is supported by three points of the second disc guide 81, the guide 182 of the guide lever 180, and the guide 112 of the regulating lever 110, and the center hole of the disc 1C is regulated to a position corresponding to the spindle motor 31. On the other hand, the loading motor 60 continues to be driven and the main slider 40 also continues to slide. The main slider 40 moves for a predetermined time from the state shown in FIG. 9, but the sub-lever 90 does not move because the cam groove corresponding to the pin 93 of the sub-lever 90 is formed parallel to the moving direction. In this state, the sub lever 9
The convex portion 91 of 0 is located in the groove 83A. The pull-in lever 80 also does not operate and continues to support the disk 1C. On the other hand, the cam lever 70 also does not operate for a predetermined time from the state shown in FIG. That is, the cam grooves corresponding to the pins 72 and 73 of the cam lever 70 are formed parallel to the moving direction of the main slider 40. FIG. 10 is a plan view of the base main body of the disk device showing a stage after the predetermined time has elapsed from the state shown in FIG. From the state shown in FIG. 10, traverse 3
The operation of 0 starts. That is, the traverse 30 starts operating in the direction in which the spindle motor 31 side approaches the lid 130.

The operation mechanism of the traverse 30 will be described with reference to FIGS. 11 to 13. FIG. 11 shows
The spindle motor 31 side of the traverse 30 is the lid 13
FIG. 3 is a plan view of the base body of the disk device showing a state in which it is operated in the direction closest to 0. From the state of FIG.
