  The moving member 51 has a horizontal portion disposed closer to the insertion opening 11 than the notch 35 of the guide arm 30 and the pressing portion 47 of the slide member 41. Further, the moving member 51 is disposed at a position where the horizontal portion 57 can contact the notch 35 of the guide arm 30. Further, in the moving member 51, the linear portion 56 is disposed on the side farther from the insertion port 11 than the pressing projection 23 of the slide cam 21, and the linear portion 56 extends along the depth direction Y with the pressing projection 23 of the slide cam 21. The linear portions 56 are arranged at positions where they can contact the pressing protrusions 23 of the slide cam 21.

  The rack member 52 has a longitudinal direction arranged parallel to the depth direction Y, and is supported by the side plate 15 so as to be slidable along the depth direction Y. The rack member 52 is attached to the moving member 51. The rack member 52 is disposed at a position where it can mesh with the gear 50.

  The coil spring 53 is stretched between the side plate 15 and the rack member 52, and urges the rack member 52 and the moving member 51 toward the insertion port 11.

  In the moving unit 29 having the above-described configuration, the guide arm 30 rotates as the CD 2 is inserted into the apparatus main body 3 through the insertion port 11, and the moving member 51 gradually moves toward the insertion port 11 by the notch 35. Pressed. At this time, since the rotational driving force of the gear 49 that rotates along the arrow A by the driving force of the motor 4 is not transmitted to the gear 50, the gear 50 moves to the arrow A along with the movement of the rack member 52 that meshes with the gear 50. Even if it rotates along, rotation of both gears is independent. Then, the rack member 52 and the gear 50 are disengaged, and the moving member 51 moves away from the notch 35 of the guide arm 30 and moves toward the insertion port 11 by the biasing force of the coil spring 53.

  Further, when the moving unit 29 ejects the CD 2 from the apparatus main body 3, if the slide cam 21 is moved away from the insertion port 11, the moving member 51 is inserted into the insertion port by the pressing protrusion 23 of the slide cam 21. 11 is pushed in a direction away from 11. The rack member 52 of the moving unit 29 meshes with the gear 50. At this time, since the rotational driving force of the gear 49 rotating along the arrow B by the driving force of the motor 4 is transmitted to the gear 50, the rack member 52, that is, the moving member 51 moves. As described above, the moving member 51 is moved by the driving force from the motor 4 that drives the transport roller 17 and is moved by the moving member driving unit 28.

  At this time, when the carriage chassis and the clamp arm 18 are moved away from each other by the movement of the slide cam 21, the urging of the spring attached to the carriage chassis to the burring 46 is released, and the slide member 41 moves away from the insertion port 11. Then, the other end 33b of the guide arm 30 contacts the outer edge of the CD2. As CD 2 is ejected, the guide arm 30 rotates in a direction in which the other end portions 33b of the arm body 33 approach each other.

  Here, the moving member 51 gradually moves in a direction away from the insertion port 11 while in contact with the one end portion 33 a of the arm main body 33 of the guide arm 30. The moving member 51 moves while pressing the one end portion 33a so that the other end portion 33b presses the CD 2 to the outside of the device main body 3.

  The CD player 1 having the above-described configuration operates as follows. First, as shown below, the CD 2 is inserted into the device body 3. At this time, as shown in FIGS. 6 and 7, the other end portions 33 b of the arm main bodies 33 of the pair of guide arms 30 are closest to each other, and the one end portion 40 a of the interlocking lever 40 is located closest to the insertion port 11. The slide member 41 is positioned at a position farthest from the insertion port 11. Further, the inner edge of the notch 35 of one guide arm 30 and the horizontal portion 57 of the moving member 51 are in contact with each other, and the rack member 52 and the gear 50 are engaged with each other. Further, the slide rack 24 and the transmission gear 20 are spaced from each other. Further, the disk guide and the transport roller 17 are close to each other, and the carriage chassis and the clamp arm 18 are separated from each other. Furthermore, the convex part 59 has come out of the concave part 58.

  In this state, the CD 2 is inserted into the device main body 3 through the insertion port 11. Then, a switch or the like provided on the device main body 3 detects that the CD 2 has been inserted into the device main body 3. Then, the motor 4 is driven to rotate the transport roller 17 in the direction in which the CD 2 is inserted into the device main body 3. Then, the gear 49 closer to the inside of the device body 3 of the gear member 48 is idled in the direction of arrow A.

  When the CD 2 is inserted into the apparatus main body 3 by the transport roller 17, the protruding pin 34 and one end portion 40a of the interlocking lever 40 are pressed by the outer edge of the CD 2, as shown in FIGS. The arm main body 33 of the guide arm 30 rotates in a direction in which the portions 33b are separated from each other, and the interlocking lever 40 rotates in a direction in which the other end portion 40b of the interlocking lever 40 approaches the insertion port 11, so that the slide member 41 is inserted into the insertion port. Move towards 11. Further, in conjunction with the rotation of the guide arm 30, it is pressed by the one end portion 33 a of the guide arm 30, and the moving member 51 of the moving unit 29 moves toward the insertion port 11. At this time, since the one-way clutch does not transmit the rotation in the above-described direction, the gear 49 of the gear member 48 idles in the arrow A direction as the rack member 52 moves toward the insertion port 11. Thus, the gear member 48 does not transmit the driving force of the motor 4 to the moving member 51.

  Then, the pressing protrusion 45 of the slide member 41 comes into contact with the pressed protrusion 22 of the slide rack 24, and the pressed protrusion 22 of the slide rack 24 is pressed toward the insertion port 11 by the pressing protrusion 45. Then, the transmission gear 20 and the slide rack 24 approach each other. Further, as shown in FIG. 10, when the CD 2 is inserted into the back of the apparatus main body 3, the transmission gear 20 and the slide rack 24 are engaged with each other, and the slide rack 24 is inserted into the insertion slot 11 by the driving force of the motor 4. Move gradually toward. When the slide rack 24 moves by a predetermined length, the slide rack 24 and the slide cam 21 are moved together toward the insertion port 11 thereafter. Also at this time, as shown in FIG. 11, the protruding pin 34 of the guide arm 30 and the one end 40a of the interlocking lever 40 are in contact with the outer edge of the CD2. Further, the pressing portion 47 of the slide member 41 presses the pressed piece 37 of the guide arm 30. Then, CD2 is positioned at the playback position.

  When the CD 2 is positioned at the reproduction position, the conveying roller 17 and the disc guide are separated from each other by the cam groove of the slide cam 21 and the plurality of cam pins, and the clamp arm 18 and the carriage chassis are close to each other, so that the CD 2 is The clamp reproduction unit 6 clamps. Further, the burring 46 is pressed by the spring of the carriage chassis, and the slide member 41 moves toward the insertion port 11 more. And as shown in FIG. 13, the protrusion pin 34 of the guide arm 30 and the one end part 40a of the interlocking lever 40 leave | separate from the outer edge of CD2. Furthermore, the rack member 52 and the gear 50 are disengaged, and the rack member 52 and the moving member 51 are further moved toward the insertion port 11 by the biasing force of the coil spring 53 as shown in FIG. Then, the moving member 51 is spaced from the one end 33 a of the arm main body 33 of the one guide arm 30. Thus, the CD player 1 clamps the CD 2 positioned at the reproduction position with the clamp reproduction unit 6, reads out information from the CD 2, and reproduces it. In this state, the slide rack 24 and the transmission gear 20 are engaged with each other.

  Next, the CD player 1 discharges the CD 2 in the device main body 3 as follows. First, when the motor 4 is driven, the conveying roller 17 is rotated in a direction in which the CD 2 is discharged out of the apparatus main body 3, and the slide rack 24 meshed with the transmission gear 20 is separated from the insertion port 11 by a predetermined length. After that, the slide rack 24 and the slide cam 21 are moved together. Then, when the slide cam 21 moves, the carriage chassis and the clamp arm 18 move away from each other, so that the urging of the spring attached to the carriage chassis to the burring 46 is released.

  Then, as shown in FIG. 15, the slide member 41 moves away from the insertion slot 11, and the one end 40a of the interlocking lever 40 and the protruding pin 34 of the guide arm 30 come into contact with the outer edge of the CD2. As shown in FIG. 14, the pressing protrusion 23 of the slide cam 21 abuts on the moving member 51 of the moving portion 29 and presses the moving member 51 in a direction away from the insertion port 11. Then, the rack member 52 moves away from the insertion port 11 against the biasing force of the coil spring 53 and meshes with the gear 50, and the moving member 51 comes into contact with the one end portion 33 a of the guide arm 30.

  Further, when the CD 2 is discharged, the interlocking lever 40 whose one end 40a is in contact with the outer edge of the CD 2 is discharged from the device body 3 by the biasing force of the spring 42 as shown in FIGS. Rotates following CD2. Further, since the gear 50 and the rack member 52 are engaged with each other, the moving member 51 gradually moves away from the insertion port 11 in a state where it is in contact with the one end portion 33a of the guide arm 30. Then, the moving member 51 moves in the direction away from the insertion port 11 while pressing the guide arm 30 in the direction in which the other end 33b ejects the CD 2 out of the device main body 3. That is, the moving member 51, that is, the pressing mechanism 8 presses the CD 2 from the rear in the CD 2 ejection direction.

  Thereafter, as shown in FIGS. 18 and 18, the pair of guide arms 30 is positioned in a state where the projecting pins 34 are closest to each other, that is, the initial position, and the CD 2 is ejected to the outside of the device body 3. Thus, as shown in FIG. 18, a part of CD2 protrudes from CD player 1 at the initial position where protruding pin 34 cannot follow CD2 any more. The moving member 51 of the pressing mechanism 8 described above presses the one end portion 33a of the guide arm 30 until the guide arm 30 is positioned at the initial position described above. In this way, the pressing mechanism 8 is driven together with the conveying roller 17 and presses the CD 2 from the rear in the ejection direction until at least a part of the CD 2 protrudes from the device main body 3. In this manner, since the CD2 is discharged by the transport unit 17 and the guide arm 30, the force for discharging the CD2 is increased.

  Further, when the CD player 1 described above discharges the CD 2, for example, if the transport roller 17 and the CD 2 slide with each other in the state shown in FIGS. 16 and 17, the CD 2 is not discharged out of the apparatus main body 3. Since the rack member 52 is engaged with the gear 50, the moving member 51 moves in a direction away from the insertion port 11. Then, the moving member 51 presses the one end portion 33 a of the guide arm 30 in a direction away from the insertion port 11. The guide arm 30 in which the moving member 51 is moved further away from the insertion port 11 by the driving force of the motor 4 and the one end 33a is pressed by the moving member 51 is a direction in which the other end 33b approaches each other. Is pressed from the moving member 51.

  Then, the other end 33 b of the arm body 33 of the guide arm 30, that is, the protruding pin 34 presses the outer edge of the CD 2 toward the outside of the device body 3. Even if the transport roller 17 and the CD 2 slide with each other, the moving member 51 presses the one end 33 a of the guide arm 30, and the guide arm 30 ejects the CD 2 to the outside of the device main body 3. Here, the conveyance roller 17 and the CD 2 slip each other. The length of the discharge distance of the CD 2 per one rotation of the conveyance roller 17 corresponds to the outer circumference of the conveyance roller 17 (in the illustrated example, the length of the outer circumference). ) Indicates less state (sliding state). As described above, the moving member 51 of the moving unit 29 of the pressing mechanism 8 is driven by the driving force of the motor 4 together with the transport unit 5 when the transport unit 5 ejects the CD 2 to the outside of the apparatus main body 3. When the five transport rollers 17 and the CD 2 slide with each other, the CD 2 is pressed toward the outside of the apparatus main body 3 through the guide arm 30.

  Further, the moving member 51 of the moving portion 29 of the pressing mechanism 8 described above allows the driving force from the motor 4 when the transport roller 17 and the CD 2 slide with each other when the transport unit 5 ejects the CD 2 out of the apparatus body 3. Thus, the projecting pin 34 provided on the other end portion 33 b of the arm body 33 presses the one end portion 33 a of the arm body 33 of the guide arm 30 in the direction in which the CD 2 is discharged out of the device body 3.

  Further, when the moving member drive unit 28 of the pressing mechanism 8 ejects the CD 2 to the outside of the apparatus main body 3, the moving member 51 is moved in contact with the one end portion 33 a of the guide arm 30, so that the transport roller 17 and the CD 2 are mutually connected. When slipping, the moving member 51 is pressed against the one end 33 a of the guide arm 30 to cause the moving member 51 to press the guide arm 30.

  The pressing mechanism 8 further includes a spring 32 as a biasing unit that biases the guide arm 30 in a direction in which the other end 33b approaches CD2, and a gear member 48 of the moving member driving unit 28. Further, the pressing mechanism 8 has a configuration in which the other end 33b of the guide arm 30 is brought into contact with the outer periphery of the CD2 to press the CD2 from the rear in the ejection direction.

  According to the present embodiment, in addition to the conveying roller 17, the pressing mechanism 8 that presses the CD 2 from the rear until a part of the CD 2 protrudes from the apparatus main body 3 is provided, so that the conveying roller 17 and the CD 2 slide with each other. However, even if the CD 2 is dirty, the CD 2 can be reliably discharged out of the apparatus main body 3.

  Further, the pressing mechanism 8 is rotatable about the one end portion 33a and the guide arm 30 as a guide member that can be in contact with the CD 2 at the other end portion 33b, and the movement for pressing the guide arm 30 by the driving force of the motor 4. And a member 51. For this reason, when the moving member 51 presses the guide arm 30, the guide arm 30 can reliably press the CD 2 out of the device main body 3.

  The pressing mechanism 8 is moved by the driving force of the motor 4 that drives the conveying roller 17. For this reason, the number of parts can be reduced, and downsizing and cost reduction can be achieved.

  Further, the pressing mechanism 8 may include a spring 32 that biases the guide arm 30. In this case, the guide arm 30 can reliably press the CD2. The pressing mechanism 8 includes a moving member drive unit 28 that restricts transmission of driving force from the motor 4 to the guide arm 30 during insertion and allows it during ejection. For this reason, the conveyance roller 17 and the moving member 51 can be reliably driven by one motor 4.
