Position to position. In other words, when the off information is input from the switch 37, the CPU 38 restricts the clamping unit 14 or the disc reproducing unit 5 from clamping the CD2.
- the CPU 38 controls the motor 22 to separate the pick-up unit 16 from the turntable 17, and the clamp pawl 20, that is, the disc reproducing unit 5 is set to the above-described clamp position. Position.
- the CPU 38 allows the clamp unit 14 or the disc reproducing unit 5 to clamp the CD2.
- the CD changer 1 having the above-described configuration first reads the information of one CD2 arbitrarily selected by the operation unit described above from among a plurality of CDs 2 accommodated in the device body 3.
- the cam members 36a and 36b should be positioned so that the protrusion 30 does not enter the cam groove 42. Further, the locking members 29 of all the trays 35 are positioned at the locking positions for locking to the outer edge of the CD 2 shown in FIG.
- the other end portion 13b of the swing chassis 13, that is, the clamp portion 14 and the pick-up portion 16 of the disc reproducing portion 5 is also retracted by a plurality of CD2 forces. Further, as shown in FIGS. 9 and 11, the intrusion portion 27 enters between the turntable 17 and the movable member 19, and the clamp pawl 20 is positioned at the unclamping position.
- the cam members 36a and 36b are moved along the thickness direction Z, and as shown in FIGS. 13 (a) and 13 (b), one arbitrarily selected CD2 from which information is read is read.
- Held tray The opening 43 of the cam groove 42 is opposed to the protrusion 30 of 35.
- the cam members 36 a and 36 b are slid along the depth direction Y and gradually approach the protrusions 30 of the tray 35.
- the projection 30 of the tray 35 holding one CD 2 described above enters the cam groove 42 through the opening 43.
- the projection 30 of the tray 35 holding one CD 2 described above passes through the horizontal portion 44 and is positioned in the rising portion 45 and moves in the rising portion 45.
- the tray 35 holding one CD2 described above gradually rises. Further, the protrusion 30 (indicated by reference numeral 30a) of the tray 35 positioned above (one side) the tray 35 holding the one CD2 is positioned above (one side) the cam portions 40, 41. A protrusion 30 (indicated by reference numeral 30b) of the tray 35 positioned below (on the other side) the tray 35 holding the one CD2 is positioned on the lower side (the other side) of the cam portions 40, 41.
- the cam members 36a and 36b move relative to the apparatus body 3 to separate the CD2 held in one tray 35 from the plurality of trays 35 and the CD2 held in the other tray 35 from each other. .
- the protrusion 30 force of the tray 35 holding the one CD 2 described above, as shown in FIGS. 14 (a) and 14 (b), is located at the intersection of the rising portion 45 and the first lowering portion 46. Then, a space is created between the tray 35 holding one CD 2 described above and the lower tray 35. Then, the swing chassis 13 rotates around one end 13a, and the other end 13b of the sliding chassis 13, that is, the pickup section 16 and the turntable 17 enter between the trays 35, that is, CD2. To do. At this time, of course, as shown in FIGS. 9 and 11, the disc reproducing unit 5 is located at the unclamping position, and the switch 37 is turned off.
- the switch 37 is turned on, and the CPU 38 controls the motor 22 to move the pickup unit 16 away from the turntable 17 and position the disc reproducing unit 5 at the clamp position. Then, the movable member 19 approaches the turntable 17 and the clamp claw 20 is locked to the CD2. Thus, the turntable 17 or the disc playback unit 5 is shown in FIGS. 10 and 12. Clamp CD2.
- the protrusion 30 is positioned on the tray switching portion 49. Then, as shown in FIG. 8, the first cam portion 40 contacts the contact portion 34 of the locking member 29 and rotates the locking member 29 against the urging force of the spring 33. Then, the locking of the tray 35 holding one CD2 to the CD2 is released.
- the cam members 36a and 36b move by moving relative to the device body 3 when reproducing the information of the CD 2 held in one of the plurality of trays 35.
- the CD 2 held on the one tray 35 is pressed against the turntable 17 of the disc reproducing unit 5 until the release of the locking of the one tray 35 to the CD 2 is completed.
- the protrusion 30 described above is located at the back of the reproduction position 50 of the cam groove 42 as shown in FIGS. 17 (a) and 17 (b). Then, the turntable 17 rotates the clamped CD2, and the pickup unit 16 reads information from the CD2 (reproduces CD2). As described above, when reproducing the information of the CD 2 held in one tray 35 among the plurality of trays 35, the disk displacement mechanism 7 moves the CD 2 locked to the one tray 35 to the disk. After clamping to the turntable 17 of the reproduction unit 5, the locking of the one tray 35 is released.
- the protrusion 30 of one tray 35 holding CD2 clamped on the turntable 17 is located behind the playback position 50 of the cam groove 42. Is located. Then, the protrusion 30 slides the cam members 36a and 36b in the direction of force from the back of the cam groove 42 toward the opening 43.
- the protrusion 30 in the cam groove 42 rises through the reproduction position 50 and switches the tray. Located in part 49. Since the protrusion 30 in the cam groove 42 rises, the one tray 35 described above approaches the CD 2 clamped on the turntable 17. Further, when the projection 30 slides the cam members 36a, 36b in the direction of the force from the back of the cam groove 42 to the opening 43, the first cam portion 40 does not contact the contact portion 34 of the locking member 29. Then, due to the urging force of the spring 33, the locking member 29 rotates, and the locking claw 32 of the locking member 29 is locked to the outer edge of the CD2.
- the protrusion 30 gradually rises through the second descending portion 48. For this reason, the one tray 35 described above is further pressed against the CD 2 clamped on the turntable 17. Then, the protrusion 30 is positioned in the clamp switching portion 47. Then, the switch 37 is turned on and off, and the CPU 38 controls the motor 22 to bring the pickup unit 16 close to the turntable 17 and position the disc reproducing unit 5 at the unclamping position described above.
- the CD2 clamp of the turntable 17 is released.
- the cam members 36a and 36b are moved with respect to the device main body 3 when stopping the reproduction of the information of one CD2, so that the CD2 clamp of the turntable 17 of the disc reproducing unit 5 is clamped.
- the disc displacement mechanism 7 locks the CD 2 clamped to the turntable 17 of the disc reproducing unit 5 to the one tray 35 when stopping the reproduction of the information of one CD 2. After that, the clamp of the turntable 17 of the disc reproducing unit 5 is released. In this way, the cam members 36a and 36b move relative to the apparatus body 3 to connect the CD2 held in one tray 35 of the plurality of trays 35 and the CD2 held in the other tray 35 to each other. Release. [0093] According to this embodiment, the CD 2 is always held on one of the tray 35 and the turntable 17 of the disc reproducing unit 5, so that the clamp and unclamp of the turntable 17 of the disc reproducing unit 5 are maintained. And switching between locking and non-locking of the CD2 of the tray 35 can be performed reliably.
- the disc displacement mechanism 7 includes movable cam members 36a and 36b on the device main body 3, and when the cam members 36a and 36b play back information on CD2, CD2 is pushed onto the disc playback section 5. At the same time, press the tray 35 against the CD2 to stop playing the information on the CD2. For this reason, when reproducing the information on CD2, CD2 can be securely clamped to disc reproducing section 5, and when stopping the reproduction of information from CD2, CD2 can be securely locked to tray 35.
- the tray 35 is brought into contact with and separated from each other, so that the power source for bringing the tray 35 into and out of contact with each other, the locking of the tray 35, and the clamp of the disk reproducing unit 5 are switched And a common power source. Therefore, the increase in the number of parts can be suppressed, and the cost can be reduced and the size can be reduced.
