Description

  The present invention relates to a disk device.

  Conventionally, in a slot-in type disk reproducing apparatus and disk recording apparatus, a disk medium inserted into a slot is transported to a disk mounting position by a disk loading mechanism disposed inside the disk apparatus. When the disc medium is ejected, the disc medium is transported to the ejection position by the disc loading mechanism (see Patent Document 1).

JP 2006-338778 A (Abstract)

  However, in the disk reproducing mechanism described in Patent Document 1, the disk medium is transported and unloaded while only the outer edge portions on both the left and right sides of the disk medium are held by the holding members. For this reason, it is difficult to always keep the disk medium being conveyed in a horizontal state, and the disk medium is inclined downward with respect to the mechanical main body due to its own weight. Since this inclination appears remarkably when the disk medium is inserted and ejected, the slot must be positioned in consideration of the inclination when the disk medium is inserted and ejected, and high accuracy is required for positioning the slot. There is a problem such as.

  Therefore, in order to solve such a problem, the present applicant firstly inclined the back side of the deck downward with respect to the case body when inserting or ejecting the disk medium when inserting or ejecting the disk medium. Proposed a disk device that can make the angle of the disk medium horizontal (Japanese Patent Application No. 2008-068410). In this disk device, slide members having a stepped portion that slides along the transport direction of the disk medium and protrudes upward are provided on both sides of the deck, and the slide member is directed downward from the top surface of the case. The deck is tilted downward by being pressed by the protruding portion that protrudes.

  If such a configuration is adopted, if a damper with a harder operation is used as a damper that supports the deck, or if the damper itself or oil is hardened due to the influence of the outside temperature, the damper that follows the operation of the slider is used. The movement becomes dull. If the following operation of the damper becomes dull, a large load is applied to the slider during operation, and there is a concern that this load may adversely affect the operation of the slider.

  The present invention has been made in view of such a problem, and an object of the present invention is to provide a disk device capable of smoothly operating the slider even when the damper supporting the deck is stiff. To do.

  In order to solve the above-mentioned problems, the present invention carries a disk medium inserted from a slot to a recording position or a reproduction position, records or reproduces information on the disk medium, and records the disk medium at the recording position or the reproduction position. A deck that is carried out toward the slot, a slot is formed, a case body that accommodates the deck so as to be movable up and down, and is arranged on both sides of the deck, and slides along the conveying direction of the disk medium, And a slide member having a step portion projecting upward, a projecting portion projecting downward from the top surface of the case body so as to correspond to the step portion, and a deck and a bottom plate of the case body. And a shock absorbing member that absorbs the shock, and protrudes upward from the step portion in the vicinity of the end portion in the transport direction of the step portion. When the protrusion slides over the protrusion, the shock absorbing member is strongly pressed, and after climbing over, it rides on the stepped portion and presses the slide member downward. The shock absorbing member is configured to be pressed with a smaller force than when overcoming the shock absorbing member.

  According to another invention, in addition to the above-described invention, the deck is pressed downward with respect to the case body in a state where the projecting portion has overcome the protrusion.

  In addition to the above-described invention, another invention is such that an inclined surface is formed on the top of the protrusion, which is inclined downward from the end side toward the opposite direction to the end.

  Furthermore, in addition to the above-described invention, another invention is an oil damper in which the impact absorbing member absorbs an impact with oil.

  According to the present invention, the slider can be operated smoothly even when the shock absorbing member supporting the deck is stiff.

Yes. In the following description, this state is referred to as a standby state. In addition, when the optical disk A is loaded to the clamp position and the optical disk A is recorded / reproduced or after the unloading of the optical disk A, the left slide member 72 moves to the foremost position as shown in FIG. The right slide member 73 has moved to the rearmost position. In the following description, this state is referred to as a reproduction state.

  As shown in FIGS. 2 and 5, in the standby state, the left L-shaped extending portion 66 rides on the left middle convex step portion 75 of the left slide portion 72 and the right L-shaped extending portion 70 slides to the right. It is in a state where it rides on the right middle convex step 81 of the member 73. For this reason, the clamper 64 provided at the front end of the clamp arm 63 is pushed upward against the urging force of the helical spring 67. Therefore, in the standby state, even if the optical disc A is at the clamp position, the optical disc A is not clamped by the turntable 95. Further, in this standby state, the left rear convex portion 37, the left front convex portion 38, the right rear convex portion 35, and the right front convex portion 36 of the cover 18 attached to the base 20 are respectively connected to the left rear convex step portion 76 and the left front convex portion.

  First, the state of the left side surface of the playback deck 14 in the standby state will be described in detail. As shown in FIG. 5A, the left rear convex portion 37 is pushed and bent in a substantially V-shaped form having a top portion 37 a from the top plate portion 21. The left rear convex portion 37 has a rear inclined portion 37b that forms the rear end side of the V shape and a front inclined portion 37c that forms the front end side of the V shape. Among these, the front inclined portion 37c has a steeply inclined portion 37d that bends with a steep inclination from the top plate portion 21, and a gently inclined portion 37e that bends with a gentle inclination from the steeply inclined portion. The left front convex portion 38 is pushed and bent in a substantially V-shaped form having a top portion 38 a from the top plate portion 21. The left front convex portion 38 includes a rear inclined portion 38b that forms the rear end side of the V shape and a front inclined portion 38c that forms the front end side of the V shape. As shown in FIG. 5A, the left rear convex portion 37 is deeply pushed and bent so that the protruding amount is larger than the left front convex portion 38.

  As described above, the left slide member 72 has the left front convex step 74, the left middle convex step 75, and the left rear convex step 76. These protrude upward from a vertically long, substantially rectangular parallelepiped left substrate portion 83. The left rear convex step 76 has a smooth top surface 76a, and has a tapered front tapered surface 76b and a rear tapered surface 76c on the front end side and the rear end side, respectively. Further, as described above, the left rear protrusion 77 is provided at the rear end portion of the left rear convex stepped portion 76. The left rear protrusion 77 has a tapered front protrusion taper surface 77a and a rear protrusion taper surface 77b on the front end side and the rear end side, respectively. The protruding rear taper surface 77b is formed to be flush with the rear taper surface 76c. In addition, a left rear slope 77c (see a partially enlarged view of FIG. 6A) that slopes downward toward the front so as to be connected to the projecting front taper surface 77a and the projecting rear taper surface 77b at the top of the left rear projection 77. ) Is formed. Further, a corner 77d having an intersection angle of about 100 degrees is formed at the boundary between the protruding rear taper surface 77b and the left rear slope 77c.

Further, the right front convex stepped portion 80, the right middle convex stepped portion 81, and the right rear convex stepped portion 82 have substantially the same amount of protrusion.

  As shown in FIG. 5B, in the standby state, the right rear convex portion 35 rides over the right front protrusion 86 and rides above the right rear convex step portion 82, and the right front convex portion 36 has the right front convex step portion 80. Riding up Specifically, the top portion 35a of the right rear convex portion 35 abuts against the top surface 82a of the right rear convex step portion 82 and presses the right rear convex step portion 82 downward, and the top portion 36a of the right front convex portion 36 is front right. The right front convex step 80 is pressed downward by coming into contact with the top surface 80a of the convex step 80. At this time, the right rear convex portion 35 has a larger protruding amount than the right front convex portion 36, so that the right rear convex step portion 82 is pressed more than the right front convex step portion 80. Therefore, although the right front convex stepped portion 80 and the right rear convex stepped portion 82 receive a pressing force, the right rear convex stepped portion 82 that is pressed more greatly pushes the oil damper 84 more than the right front convex stepped portion 80. It descends greatly. As a result, the right side of the playback deck 14 is inclined so that the rear end side is lower than the front end side. Further, the right rear extending portion 70a of the right L-shaped extending portion 70 rides above the right middle convex step portion 81 and engages with a V-shaped cut. For this reason, the right side of the clamp arm 63 is pushed upward against the urging force of the helical spring 67.

  Thus, in the standby state, the playback deck 14 stands by in a state where the left and right rear sides are lowered below the front side. This standby state is achieved by moving the left slide member 72 to the rear side and the right slide member 73 to the front side when the disk device 10 detects the loading of the optical disk A. When the disc device 10 detects the ejection of the optical disc A, both slide members 72 and 73 return to the original state, and the reproduction deck 14 becomes horizontal.

  Next, the state of the playback deck 14 in the disk device 10 in the playback state will be described in detail.

  FIG. 6 is a schematic view of the disk device 10 according to an embodiment of the present invention seen transparently from the side surface in the reproduction state, and FIG. 6A is a view seen from the left side and a partially enlarged view thereof. , (B) is a diagram viewed from the right side and a partially enlarged view thereof.

  First, the state of the left side surface of the playback deck 14 in the playback state will be described in detail. As shown in FIG. 6A, in the playback state, the left slide member 72 is positioned most forward. For this reason, the rear end of the left slide member 72 moves to the front of the left rear convex portion 37, and the left rear convex portion 37 climbs over the left rear convex stepped portion 76 to get over the left rear projection 77, It will be in the state located behind the left back convex step part 76. FIG. Further, the left front convex portion 38 is located inside a left front concave portion 87 formed between the left middle convex step portion 75 and the left front convex step portion 74. Therefore, the left slide member 72 does not come into contact with the left rear convex portion 37 and the left front convex portion 38, and is not pressed downward by the left rear convex portion 37 and the left front convex portion 38. For this reason, the left side of the reproduction deck 14 is supported by the oil damper 84 to maintain a horizontal state. Further, the left front extending portion 66 a is located inside a left rear concave portion 88 formed between the left middle convex step portion 75 and the left rear convex step portion 76. For this reason, the left front extending portion 66 a is not pushed upward against the urging force of the helical spring 67. As a result, the left side of the clamp arm 63 is pushed down by the urging force of the helical spring 67.

  Next, the state of the right side surface of the playback deck 14 in the playback state will be described in detail. As shown in FIG. 6B, in the playback state, the right slide member 73 is located most rearward. For this reason, the right front convex step portion 80 of the right slide member 73 has moved to the rear of the right front convex portion 36. In addition, the right rear convex portion 35 is formed between the right middle convex step portion 81 and the right front convex step portion 80 from the state of riding on the right rear convex step portion 82 and over the right front protrusion 86. The state is located inside the rear recess 90. Accordingly, the right slide member 73 does not come into contact with the right rear convex portion 35 and the right front convex portion 36, and is not pressed downward by the right rear convex portion 35 and the right front convex portion 36. For this reason, the right side of the reproduction deck 14 is supported by the oil damper 84 to maintain a horizontal state. Further, the right rear extension 70a is disengaged from the engagement with the V-shaped notch formed on the top surface 81a of the right middle convex step 81, and between the right middle convex step 81 and the right front convex step 80. It is located in the inside of the right front recessed part 91 formed. For this reason, the right rear extension part 70 a is not pushed upward against the urging force of the helical spring 67. As a result, the right side of the clamp arm 63 is pushed down by the urging force of the helical spring 67.

  Thus, the playback deck 14 maintains a horizontal state in the playback state. In the reproduction state, the clamper 64 applies a force to push down the reproduction deck 14 downward by the urging force of the helical spring 67 locked to the clamp arm 63.

  Next, operations after the optical disc A is inserted from the slot 16 and operations ejected from the slot 16 will be described.

  FIG. 7 is a schematic side view for explaining the state of the optical disc A after being inserted into the slot 16. FIG. 7A is a view for explaining the state immediately after the optical disc A is inserted into the slot 16. FIG. 6B is a diagram for explaining a state in the middle of the optical disc A being carried in toward the clamp position of the reproduction deck 14. Next, FIG. 8 is a schematic side view for explaining the state of the optical disc A after being inserted into the slot 16, and FIG. 8A shows the state where the optical disc A has reached the clamp position of the playback deck 14. (B) is a diagram for explaining a state in which the optical disc A is clamped in the reproduction deck 14. 7 and 8, it is assumed that a decorative panel 92 is disposed in front of the front wall portion 53 of the case body 12 at a predetermined distance.

  As shown in FIG. 7A, the optical disc A is inserted from a panel slot 92 a provided in the decorative panel 92. When the optical disc A is inserted into the panel slot 92a, the reproduction deck 14 is in a standby state (see FIG. 5). Therefore, when the optical disc A is inserted into the panel slot 92a, the playback deck 14 is in a state where the rear end side thereof is slightly inclined downward (see FIGS. 5 and 7A). When the optical disk A is sequentially inserted into the panel slot 92 a and the slot 16, the optical disk A is conveyed toward the clamp position while being guided by the disk guide 62 in the reproduction deck 14. Immediately after the optical disc A is inserted into the panel slot 92a and the slot 16, the rear end A1 of the optical disc A is held between the disc guide 62 and the feed roller 93 (see FIG. 7A). . Since the playback deck 14 is tilted at the rear end side, the disc guide 62 is tilted so that the rear end side is lowered. Therefore, the optical disc A, the rear end portion A1 of which is held between the disc guide 62 and the feed roller 93, is guided by the disc guide 62 so that the rear end side thereof is inclined downward. However, since the optical disc A immediately after insertion is in a state in which only the rear end side thereof is supported by the disc guide 62 and the feed roller 93, the front end portion A2 which is a free end has a moment B which is directed downward due to the own weight of the optical disc A itself. Works. For this reason, the moment B, which is self-gravity, prevails compared to the force that causes the rear end side to tilt downward by the disc guide 62, and the optical disc A has the front end portion A2 (the side opposite to the carry-in side) slightly downward. It will be in an inclined state (see FIG. 7A).

  When the optical disc A is further carried in from the state of FIG. 7A, the rear side from the center of the optical disc A is sandwiched between the disc guide 62 and the feed roller 93 (see FIG. 7B). In this state, the front end A2 of the optical disc A is located in the vicinity of the panel slot 92a. The playback deck 14 still maintains a standby state in which the rear end side is inclined low. Therefore, a force is applied to the optical disc A so that the rear end side of the optical disc A is inclined downward. However, in this state, the optical disc A is supported by the disc guide 62 and the feed roller 93 on the rear side from the center. For this reason, the moment B1 acts on the front end portion A2 of the optical disc A, but the moment B1 balances with the force acting so that the rear end side is inclined low by the disc guide 62, and the optical disc A maintains a substantially horizontal state. (See FIG. 7B).

  When the optical disc A is further carried in from the state of FIG. 7B, the optical disc A is guided to the clamp position. At the clamp position, the center of the optical disc A is located above the spindle motor 94 provided in the reproduction deck 14. In this state, the vicinity of the front end portion A2 of the optical disc A is held by the disc guide 62 (see FIG. 8A). The playback deck 14 still maintains a standby state in which the rear end side is inclined low. Further, the optical disc A is in a state where the back surface or the rear end A1 thereof is supported by a tray (not shown) disposed inside the reproduction deck 14. For this reason, the optical disc A maintains a state substantially parallel to the reproduction deck 14. That is, the optical disk A maintains a state in which the rear end side is inclined obliquely downward with respect to the disk device 10 (see FIG. 8A).

  As shown in FIG. 8A, when the optical disc A is conveyed to the clamp position, the optical disc A is pressed downward by the clamper 64 and mounted on the turntable 95 attached to the spindle motor 94 (FIG. 8 ( B)). When the optical disc A is mounted on the turntable 95, the playback deck 14 shifts from the standby state shown in FIG. 5 to the playback state shown in FIG. ing.

  The state in which the optical disc A is inserted has been described with reference to FIGS. 7A, 7B, 8A, and 8B. This is illustrated in FIGS. 8B, 8A, and 8B. 7B and FIG. 7A, even if the optical disk A is ejected, the optical disk A ejected in the state of FIG. Is maintained.

  Here, an operation of the playback deck 14 shifting from the standby state to the playback state will be described. The playback deck 14 shifts from the standby state to the playback state after the optical disk A is transported to the clamp position in the playback deck 14, and after the optical disk A is completely ejected from the playback deck 14, the playback deck 14 changes from the standby state to the playback state. Transition to a similar state. FIG. 9 is a schematic view transparently seen from the side of the playback deck 14 in the middle of transition from the standby state to the playback state. FIG. 9A shows that the top portion 37a and the left rear slope 77c are in contact with each other. It is the figure which looked at the state from the left side, (B) is the figure which looked at the state which the top part 35a and the right front slope 86c contacted from the right side. FIG. 10 is a schematic view transparently seen from the side of the state where the playback deck 14 is in the transition from the standby state to the playback state. FIG. 10A shows a contact between the gently inclined portion 37e and the corner portion 77d. (B) is a view of the state where the gently inclined portion 35e and the corner portion 86d are in contact with each other as seen from the right side.

  First, the operation on the left side of the playback deck 14 will be described. As described above, in the standby state, the left rear convex portion 37 rides above the left rear convex step portion 76, and the left front convex portion 38 rides above the left front convex step portion 74. Moreover, the left front extension part 66a has climbed over the left middle convex part 75 (refer FIG. 5 (A)). When the left slide member 72 moves forward from this state, the left rear convex stepped portion 76 slides forward while the top surface 76a is in contact with the top portion 37a of the left rear convex portion 37. The convex step portion 74 also slides forward with the top surface 74a in contact with the top portion 38a of the left front convex portion 38. The left middle convex step 75 also slides forward with its top surface 75a in contact with the top 66b of the left front extension 66a.

  When the left slide member 72 moves forward by a certain amount from the state of FIG. 5A, the force to always return to the original position of the oil damper 84 continues to work strongly during this period, so the left rear convex step 76. From the state in which the top surface 76a of the left rear convex portion 37 and the top portion 37a of the left rear convex portion 37 are in contact with each other by the restoring force of the oil damper 84, the rear inclined portion 37b of the left rear convex portion 37 and the projecting front tapered surface 77a of the left rear projection 77 are The contact is made by the restoring force of the oil damper 84. Further, when the left slide member 72 moves forward, the projecting front taper surface 77a slides forward while contacting the rear inclined portion 37b, and the top portion 37a of the left rear convex portion 37 is left rear projection. 77 is in contact with the left rear slope 77c (see FIG. 9A). Further, when the left slide member 72 moves forward, the left rear slope 77c slides forward while contacting the top portion 37a, and the corner portion 77d of the left rear protrusion 77 is in contact with the top portion 37a. Then, the corner portion 77d comes into contact with the gently inclined portion 37e. Further, when the left slide member 72 moves forward by a certain amount, the corner portion 77d slides forward while contacting the gently inclined portion 37e (see FIG. 10A). Thereafter, the projecting rear taper surface 77b and the rear taper surface 76c come into surface contact with the steep inclined portion 37d, and the projecting rear taper surface 77b and the rear taper surface 76c slide forward while making surface contact with the steep inclined portion 37d. I will do it. Thereafter, the left rear convex stepped portion 76 is released from contact with the left rear convex portion 37 and is positioned in front of the left rear convex portion 37 (see FIG. 6A). That is, as the left slide member 72 moves forward, the left rear convex portion 37 climbs over the left rear projection 77 from the state of riding on the top surface 76a of the left rear convex step portion 76, and the left rear convex portion It will move to the rear side of the stepped portion 76. At this time, the left rear protrusion 77 is formed with the protrusion front taper surface 77 a and the left rear slope 77 c, so that the left rear protrusion 37 can smoothly ride on the left rear protrusion 77 without being caught by the left rear protrusion 77. Is possible.

  The front left convex stepped portion 74 slides forward while the top surface 74a is in contact with the top portion 38a of the left front convex portion 38, and then the rear tapered surface 74c is in surface contact with the front inclined portion 38c. It becomes. The rear taper surface 74c slides forward while making surface contact with the front inclined portion 38c. Further, when the left slide member 72 moves forward, the left front convex stepped portion 74 is released from contact with the left front convex portion 38 and is placed in the left front concave portion 87 (see FIG. 6A). .

  The left middle convex step 75 also slides forward while the top surface 75a is in contact with the top 66b of the left front extension 66a. Thereafter, the rear tapered surface 75c comes into surface contact with the front inclined portion 66c of the left front extending portion 66a, and the rear tapered surface 75c slides forward while making surface contact with the front inclined portion 66c. Further, when the left slide member 72 moves forward, the left front extending portion 66a is released from contact with the left middle convex step portion 75 and is placed in the left rear concave portion 88 (FIG. 6 ( A)).

  When the left front convex stepped portion 74 and the left rear convex stepped portion 76 are released from contact with the left front convex portion 38 and the left rear convex portion 37, the rear end side of the left side of the reproduction deck 14 is caused by the restoring force of the oil damper 84. The state (see FIG. 5A) inclined obliquely downward is changed to a horizontal state (see FIG. 6A). In addition, since the oil damper 84 is used as the shock absorbing member, the left side of the reproduction deck 14 is slowly shifted from the inclined state to the horizontal state. Further, the left front extending portion 66 a is released from contact with the left middle convex stepped portion 75 and enters the left rear concave portion 88. For this reason, the left side of the clamp arm 63 is pushed down by the biasing force of the helical spring 67.

  Next, the operation of the right side surface of the playback deck 14 will be described. As described above, in the standby state, the right rear convex portion 35 rides above the right rear convex step portion 82, and the right front convex portion 36 rides above the right front convex step portion 80. Further, the right rear extension 70a rides above the right middle convex step 81 and engages with a V-shaped cut (see FIG. 5B). When the right slide member 73 moves rearward from this state, the top surface 82a of the right rear convex step 82 slides rearward while in contact with the top 35a of the right rear convex portion 35, and the right front convex step. The top surface 80a of the portion 80 also slides rearward while in contact with the top portion 36a of the right front convex portion 36. Further, the right rear extension 70a is disengaged from the notch formed in the right middle convex step 81 and faces rearward with the top surface 81a in contact with the top 70b of the right rear extension 70a. Slide.

  When the right slide member 73 moves a certain amount rearward from the state of FIG. 5B, the top surface 82a of the right rear convex stepped portion 82 and the top portion 35a of the right rear convex portion 35 come into contact like the left side surface. From this state, the front inclined portion 35c of the right rear convex portion 35 and the protruding rear taper surface 86b of the right front protrusion 86 are in contact with each other. Further, when the right slide member 73 moves rearward, the protruding rear taper surface 86b slides rearward while contacting the front inclined portion 35c, and the top portion 35a of the right rear convex portion 35 is moved to the right front protrusion 86. Is in contact with the right front slope 86c (see FIG. 9B). Further, when the right slide member 73 moves rearward, the right front slope 86c slides rearward while being in contact with the top 35a, and the corner 86d of the right front protrusion 86 is in contact with the top 35a. The corner portion 86d comes into contact with the gently inclined portion 35e. Further, when the right slide member 73 moves by a certain amount toward the rear, the corner 86d slides toward the rear while being in contact with the gently inclined portion 35e (see FIG. 10B). Thereafter, the projecting front taper surface 86a and the front taper surface 82b are in surface contact with the steep inclined portion 35d, and the projecting front taper surface 86a and the front taper surface 82b slide forward while contacting the steep inclined portion 35d. I will do it. Thereafter, the right rear convex stepped portion 82 is released from contact with the right rear convex portion 35 and is in a state of being accommodated in the right rear concave portion 90 (see FIG. 6B). That is, as the right slide member 73 moves rearward, the right rear convex portion 35 climbs over the right front protrusion 86 from the state of riding on the top surface 82a of the right rear convex step portion 82, and then enters the right rear concave portion 90. Will move to. At this time, since the right front protrusion 86 is formed with the protrusion rear taper surface 86b and the right front slope 86c, the right rear protrusion 35 can smoothly ride on the right front protrusion 86 without being caught by the right front protrusion 86. .

  Further, the front right convex stepped portion 80 slides backward while the top surface 80a is in contact with the top portion 36a of the right front convex portion 36, and then the front tapered surface 80b is in surface contact with the rear inclined portion 36b. It becomes. The front tapered surface 80b slides forward while making surface contact with the rear inclined portion 36b. Further, when the right slide member 73 moves rearward, the right front convex step portion 80 is released from contact with the right front convex portion 36 and is positioned behind the right front convex portion 36 (see FIG. 6B). ).

  The right middle convex step 81 is disengaged from the engagement with the right rear extension 70a, and the top surface 81a slides rearward while contacting the top 70b of the right rear extension 70a. Thereafter, the front tapered surface 81b comes into surface contact with the rear inclined portion 70c of the right rear extension 70a, and the front tapered surface 81b slides rearward while making surface contact with the rear inclined portion 70c. Further, when the right slide member 73 moves rearward, the right rear extension portion 70a is released from contact with the right middle convex step portion 81 and is in a state of being accommodated in the right front concave portion 91 (FIG. 6B). )reference).

  When the right front convex step portion 80 and the right rear convex step portion 82 are released from contact with the right front convex portion 36 and the right rear convex portion 35, the rear end side of the right side of the reproduction deck 14 is moved by the restoring force of the oil damper 84. From a state inclined obliquely downward (see FIG. 5B) to a horizontal state (see FIG. 6B). In addition, since the oil damper 84 is used as the impact absorbing member, the right side of the reproduction deck 14 slowly shifts from a state inclined obliquely downward to a horizontal state. Further, the right rear extension 70 a is released from contact with the right middle convex step 81 and is accommodated in the right front recess 91. For this reason, the right side of the clamp arm 63 is pushed down by the biasing force of the helical spring 67.

  When the reproduction of the optical disc A is completed, the optical disc A is ejected from the slot 16 to the outside of the disc device 10. The operation of ejecting the optical disk A from the slot 16 is mainly the operation opposite to the operation of insertion. First, as shown in FIG. 8B, the rear end side of the playback deck 14 is inclined downward from the state in which the optical disc A is pressed downward by the clamper 64 and is mounted on the turntable 95 (playback state). Transition to the standby state. At this time, the optical disc A is removed from the turntable 95 and is maintained substantially parallel to the playback deck 14 (see FIG. 8A). Thereafter, the optical disc A is transported forward while maintaining a state substantially parallel to the reproduction deck 14. When the front end portion A2 of the optical disc A passes through the vicinity of the slot 16 and the panel slot 92a, the optical disc A maintains a substantially horizontal state as described above (see FIG. 7B). Further, as the optical disc A is transported forward, the moment B acts on the optical disc A as described above, and the optical disc A is slightly inclined toward the front side.

  Next, the operation of the playback deck 14 shifting from the playback state to the standby state will be described.

  First, the operation on the left side of the playback deck 14 will be described. The operation when the playback deck 14 shifts from the playback state to the standby state is the reverse operation of the slide member 72 that shifts from the standby state to the playback state described above. In the reproduction state, the left rear convex step 76 is positioned in front of the left rear convex portion 37, and the left front convex portion 38 is housed in the left front concave portion 87. Further, the left front extending portion 66a is housed in the left rear recess 88 (see FIG. 6A). When the left slide member 72 moves rearward from this state, the projecting rear taper surface 77b and the rear taper surface 76c come into surface contact with the steep inclined portion 37d, and the projecting rear taper surface 77b and the rear taper surface 76c are in the steep inclined portion 37d. And slides backward while making surface contact. Further, when the left slide member 72 moves rearward, the corner portion 77d of the left rear protrusion 77 comes into contact with the gently inclined portion 37e, and the corner portion 77d moves backward while contacting the gently inclined portion 37e. It slides (see FIG. 10A). Further, when the left slide member 72 moves rearward, the top portion 37a of the left rear protrusion 37 is in contact with the corner portion 77d of the left rear protrusion 77, and the top portion 37a is in contact with the left rear slope 77c. (See FIG. 9A). Further, when the left slide member 72 moves rearward, the left rear slope 77c slides rearward while being in contact with the top portion 37a, and the rear inclined portion 37b of the left rear convex portion 37 and the left rear protrusion 77 are moved. The top 37a of the left rear convex portion 37 comes into contact with the top surface 76a of the left rear convex step portion 76 through the state of contact with the protruding front taper surface 77a. Thereafter, when the left slide member 72 further moves rearward and a reproduction position detection switch (not shown) is operated, the movement is stopped (see FIG. 5A).

  That is, with the rearward movement of the left slide member 72, the left rear convex portion 37 climbs over the left rear projection 77 from the position on the rear side of the left rear convex stepped portion 76, and rides on the top surface 76a. Furthermore, it will move a little. Further, in the present embodiment, since the oil damper 84 is used as the shock absorbing member, the top surface 76a of the left rear convex stepped portion 76 from the state in which the top portion 37a of the left rear convex portion 37 is in contact with the left rear slope 77c. The oil damper 84 is slowly restored when moving to the state in contact with the top and when moving on the top surface 76a, and does not suddenly restore. For this reason, the left slide member 72 does not receive a large load when moving from the state where the top portion 37a is in contact with the left rear slope 77c to the state where it is in contact with the top surface 76a and when moving on the top surface 76a. It will be possible to move smoothly toward the rear.

  On the other hand, when the left slide member 72 moves rearward, the front inclined portion 38c comes into surface contact with the rear tapered surface 74c from the state in which the left front convex portion 38 is housed in the left front concave portion 87 (see FIG. 6A). It will be in a state (refer to Drawing 10 (A)). Further, when the left slide member 72 moves rearward, the rear taper surface 74c slides rearward while being in surface contact with the front inclined portion 38c, and the left front convex portion 38 is above the left front convex step portion 74. The top surface 74a of the left front convex stepped portion 74 and the top portion 38a of the left front convex portion 38 are in contact with each other (see FIG. 5A).

  Further, when the left slide member 72 moves rearward, the left front extending portion 66a is moved from the state where the left front extending portion 66a is housed in the left rear recessed portion 88 (see FIG. 6A), and the front inclined portion 66c is changed to the left middle convex step portion. 75 is in surface contact with the rear taper surface 75c (see FIG. 10A). Further, when the left slide member 72 moves rearward, the rear taper surface 75c slides rearward while being in surface contact with the front inclined portion 66c, and the left front extension portion 66a is a left middle convex step portion. The top surface 75a of the left middle convex step 75 and the top 66b of the left front extension 66a are in contact with each other (see FIG. 5A).

  When the left front convex portion 38 and the left rear convex portion 37 ride on the left front convex step portion 74 and the left rear convex step portion 76, respectively, the oil damper 84 is pressed by the pressing force from the left front convex portion 38 and the left rear convex portion 37. Is pushed, and the rear end side of the playback deck 14 is inclined obliquely downward (see FIG. 5A). Further, when the left front extending portion 66 a rides above the left middle convex step portion 75, the left side of the clamp arm 63 is pushed up against the urging force of the helical spring 67.

  Next, the operation of the right side surface of the playback deck 14 will be described. The operation when the playback deck 14 shifts from the playback state to the standby state is the reverse operation of the slide member 73 that shifts from the standby state to the playback state described above. In the reproduction state, the right rear convex portion 35 is housed in the right rear concave portion 90, and the right front convex step portion 80 is located behind the right front convex portion 36. Further, the right rear extension 70a is housed in the right front recess 91 (see FIG. 6B). When the right slide member 73 moves forward from this state, the projecting front taper surface 86a and the front taper surface 82b are in surface contact with the steep inclined portion 35d, and the projecting front taper surface 86a and the front taper surface 82b are steep inclined portions 35d. And slides forward while in surface contact. Further, when the right slide member 73 moves forward, the corner portion 86d of the right front protrusion 86 comes into contact with the gently inclined portion 35e, and the corner portion 86d slides forward while contacting the gently inclined portion 35e. It moves (see FIG. 10B). Further, when the right slide member 73 moves forward, the top 35a of the right rear protrusion 35 is in contact with the corner 86d of the right front protrusion 86, and the top 35a is in contact with the right front slope 86c. (See FIG. 9B). Further, when the right slide member 73 moves forward, the right front slope 86c slides forward while being in contact with the top portion 35a, and the front inclined portion 35c of the right rear convex portion 35 and the protrusion of the right front protrusion 86 are projected. After the state where the rear taper surface 86b is in contact, the top portion 35a of the right rear convex portion 35 is in contact with the top surface 82a of the right rear convex step portion 82. Thereafter, the right slide member 73 further moves forward, and when the reproduction position detection switch (not shown) is operated, the movement stops (see FIG. 5B).

  That is, as the right slide member 73 moves forward, the right rear convex portion 35 gets over the right front protrusion 86 from the position of the right rear concave portion 90, rides on the top surface 82a, and further moves slightly. Become. Further, in the present embodiment, since the oil damper 84 is used as the shock absorbing member, the top surface 82a of the right rear convex step portion 82 is in a state where the top portion 35a of the right rear convex portion 35 is in contact with the right front slope 86c. The oil damper 84 is slowly restored when moving to the contact state and when moving on the top surface 82a, and is not restored rapidly. For this reason, the right slide member 73 does not receive a large load when moving from the state in which the top portion 35a is in contact with the right front slope 86c to the state in which the top 35a is in contact with the top surface 82a and when moving on the top surface 82a. It will be possible to move smoothly toward.

  On the other hand, when the right slide member 73 moves forward, the right front convex portion 36 is located on the front side of the right front convex stepped portion 80 (see FIG. 6B), and the rear inclined portion 36b is moved to the front tapered surface 80b. It will be in the state of surface contact (refer to Drawing 10 (B)). Further, when the right slide member 73 moves forward, the front tapered surface 80b slides forward while being in surface contact with the rear inclined portion 36b, and the right front convex portion 36 is above the right front convex step portion 80. The top surface 80a of the right front convex step portion 80 and the top portion 36a of the right front convex portion 36 are in contact with each other (see FIG. 5B).

  Further, when the right slide member 73 moves forward, the right rearward extending portion 70a is in the right front concave portion 91 (see FIG. 6B), and the rear inclined portion 70c is the right middle convex step portion 81. Is brought into surface contact with the front taper surface 81b (see FIG. 10B). Further, when the right slide member 73 moves forward, the front tapered surface 81b slides forward while being in surface contact with the rear inclined portion 70c, and the right rear extending portion 70a is a right middle convex step portion. Get on top of 81. Then, the top surface 81a of the right middle convex step portion 81 and the top portion 70b of the right rear extension portion 70a slide while in contact with each other, and the right rear extension portion 70a engages with the notch of the right middle convex step portion 81. (See FIG. 5B).

  When the right front convex portion 36 and the right rear convex portion 35 ride on the right front convex step portion 80 and the right rear convex step portion 82, respectively, the oil damper 84 is pressed by the pressing force from the right front convex portion 36 and the right rear convex portion 35. Is compressed, and the rear side of the right side of the playback deck 14 is inclined obliquely downward (see FIG. 5B). Further, the right rear extending portion 70 a is engaged with the notch of the right middle convex step portion 81, whereby the right side of the clamp arm 63 is pushed up against the urging force of the helical spring 67.

  In the disk device 10 configured as described above, the left rear protrusion step 76 and the right rear protrusion step portion 82 are provided with a left rear protrusion 77 and a right front protrusion 86, respectively. An oil damper 84 is used as an impact absorbing member. The oil damper 84 requires a certain amount of time until it completely returns to its original state after the support portion is pushed in. For this reason, when the left slide member 72 and the right slide member 73 are released from the pressing by the left rear convex portion 37, the right rear convex portion 35, etc., the reproduction deck 14 slowly takes time from the inclined state to the substantially horizontal state. Return. Therefore, when the left slide member 72 and the right slide member 73 are slid rearward and forward, respectively, and the reproduction deck 14 is shifted to the standby state, the left rear protrusion 37 and the right rear protrusion 35 are the left rear protrusion 77 and the right front protrusion. 86, the time from the time when the top 86a is reached to the top surfaces 76a, 82a of the left rear convex step portion 76 and the right rear convex step portion 82 is delayed or the force applied to the top surfaces 76a, 82a is increased by a predetermined time. It becomes possible to weaken only. Therefore, the left rear protrusion 77 and the right front protrusion 86 are pressed by the left rear protrusion 37 and the right rear protrusion 35 to excessively press the oil damper 84, and then the left rear protrusion 37 and the right rear protrusion 35 are pressed. Each of the left slide member 72 and the right slide member 73 can be slid to some extent until they come into contact with the left rear convex step portion 76 and the right rear convex step portion 82, respectively. Or even if contact occurs quickly, the load at that time can be reduced. Therefore, the left slide member 72 and the right slide member 73 can be slid without applying loads from the left rear convex step portion 76 and the right rear convex step portion 82, respectively. As a result, the left slide member 72 and the right slide member 73 can be smoothly slid. Therefore, when the oil damper 84 is hardened due to factors such as a decrease in the temperature of the outside air, the oil damper 84 is pressed while reliably pressing the oil damper 84 by pressing the left rear protrusion 77 and the right front protrusion 86. In this state, the left slide member 72 and the right slide member 73 can be slid. For this reason, even when the oil damper 84 is cured, the left slide member 72 and the right slide member 73 can be smoothly slid without applying a load to the left slide member 72 and the right slide member 73.

  In the disk device 10, a left rear slope 77 c and a right front slope 86 c are formed at the tops of the left rear protrusion 77 and the right front protrusion 86. For this reason, the left slide member 72 and the right slide member 73 are respectively placed in a state in which the left rear convex portion 37 and the right rear convex portion 35 ride on the left rear convex step portion 76 and the right rear convex step portion 82, respectively. When slid forward and backward, the left rear protrusion 37 and the right rear protrusion 35 can smoothly get over the left rear protrusion 77 and the right front protrusion 86 without being caught by the left rear protrusion 77 and the right front protrusion 86, respectively. It becomes possible. Accordingly, it is possible to smoothly slide the left slide member 72 forward and the right slide member 73 backward, respectively.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and can be implemented in various modifications.

  In the above-described embodiment, the left rear protrusion 77 and the right front protrusion 86, which are protrusions, are provided only on the left rear convex step portion 76 and the right rear convex step portion 82, respectively. It is not limited to the convex step portion 76 and the right rear convex step portion 82. For example, in the vicinity of the rear end portion of the left front convex step portion 74 or the left middle convex step portion 75 or the front end of the right front convex step portion 80 or the right middle convex step portion 81 A protrusion may be provided in the vicinity of the portion. Further, in addition to the left rear convex stepped portion 76 and the right rear convex stepped portion 82, a protrusion may be provided on the left front convex stepped portion 74 and the right front convex stepped portion 80. In this case, when the reproduction deck 14 gets over each protrusion, the reproduction deck 14 is pressed downward without tilting in any of the front and rear directions, and the pressure presses oil dampers 84 provided at substantially four corners of the reproduction deck 14. Thereby, in addition to the left rear convex step portion 76 and the right rear convex step portion 82, the left front convex step portion 74 and the right front convex step portion 80 can be smoothly slid.

  In the above-described embodiment, the left rear slope 77c and the right front slope 86c, which are tapered slopes, are formed at the tops of the left rear protrusion 77 and the right front protrusion 86, respectively. The form is not limited to a tapered slope, and may be a curved slope, for example. Further, the left rear slope 77c and the right front slope 86c may not be formed.

  In the above-described embodiment, the oil damper 84 is used as the shock absorbing member. However, the shock absorbing member is not limited to the oil damper, and it takes a certain amount of time to return after being pressed. If so, it is possible to employ other types of shock absorbing members such as rubber dampers and springs.

  Further, in the above-described embodiment, the playback deck 14 is tilted during standby, but the installation of the left rear projection 77 and the right front projection 86 is an impact absorbing member that takes a certain amount of time to return after being pressed. The present invention can be applied to any device that can be used and that must move the slide member when the shock absorbing member is loaded.
