- the disc feed mechanism 50 includes an arm 421 whose one end abuts the optical disc 1 and whose other end is rotatable, and a connecting member 423 whose one end is connected to the arm 421.
- the other end of the connecting member 423 is connected to a first drive cam 44 that is driven to advance and retreat.
- the connecting member 423 and the first drive cam 44 have a rotation amount of the arm 421 when the optical disk 1 is large.
- the disk feed cam 51 is provided to increase the amount of rotation of the arm 421.Therefore, the diameter of the optical disk 1 is determined by the rotation angle of the arm 421. Based on this determination, the connecting member 423 and the first drive cam 44 are relatively moved by the disc feed cam portion 51. Therefore, even if the diameter of the optical disk 1 is different, the optical disk 1 can be accurately sent to the turntable 23 by a simple means called a cam according to the diameter.
- the disc feeding cam portion 51 includes a protrusion 52 provided on the connecting member 423, and a cam groove 53 that is engaged with the protrusion 52 and formed in the first drive cam 44.
- the cam groove 43 includes a first cam groove 53A for feeding the large optical disk 1 and a second cam groove 53B for feeding the small optical disk 1.
- the disc feeding cam portion 51 can be formed with a simple structure in which the cam groove is formed and the projection 52 is provided on the connecting member 423. Therefore, the cost for manufacturing the disc feeding cam portion 51 can be reduced.
- the second disk delivery mechanism also serves as the disk guide mechanism 41, the number of parts can be reduced, and the disk device can be reduced in size and cost.
- the first disk delivery mechanism 61 includes eject arms 611 and 612 that have one end rotatably supported inside the apparatus main body 10 and the other end abutted against the peripheral edge of the optical disk 1. It is configured. Therefore, since the optical disc 1 can be easily sent out to the slot 10A side by rotating around one end of the eject arms 611 and 612, the structure of the first disc delivery mechanism 61 can be simplified. .
- the actuator 29 is configured to separate the objective lens 28 from the optical disk 1 in accordance with the insertion or ejection of the optical disk 1.
- the disc ejection mechanism 43 passes through the window 21B. Therefore, the actuator 29 is operated in response to the insertion or ejection of the optical disc 1, thereby causing interference between the objective lens 28 and the disc ejection mechanism 43. It can be surely prevented.
- the disk device is provided with a switch for inserting or ejecting the optical disk 1 from the slot 10A, and is configured to separate the objective lens 28 from the optical disk 1 by detecting the pressing of the switch.
- the actuator 29 is operated, and the interference between the objective lens 28 and the disc ejection mechanism 43 can be surely prevented.
- the disk discharge mechanism 43 that discharges the optical disk 1 disposed on the turntable 23 toward the slot 10A is described as a shielding object.
- the shielding object of the present invention is not limited to this. It is not something. That is, any member that passes on the plane of the cover 21A of the disk device corresponds to the shielding portion, and therefore the present invention can protect the pickup mechanism 24 including the object lens 28 from the shielding object. .
- the force that includes the disk guide mechanism 41 as the disk discharge mechanism 43 can also be applied to a configuration without the id mechanism 41.
- the eject arms 611 and 612 are formed long, their tips may reach the pickup mechanism 24 in the standby state and become a shielding object. Is possible.
- the lens holder 292 has three positions: a standby position, a position closer to the force bar 21A (optical disc 1) than the standby position, and a position where the cover 21A (optical disc 1) force is separated from the standby position.
- a standby position a position closer to the force bar 21A (optical disc 1) than the standby position
- a position where the cover 21A (optical disc 1) force is separated from the standby position it may be possible to switch at two positions.
- the apparatus main body 10 provided with the slot 1 OA for inserting and ejecting the optical disk 1 and the optical disk 1 which is provided inside the apparatus main body 10 and rotates are driven.
- a pickup mechanism 24 that irradiates light through an objective lens 28 facing the optical disk 1, a pickup feed mechanism 25 that moves the pickup mechanism 24 close to and away from the turntable 23, and a pickup mechanism 25
- a window 21B cut out along the feed direction is formed, and a substantially flat cover 21A provided inside the apparatus main body 10 is provided, and the disc is ejected as a shield so as to pass through the window 21B.
- the objective lens 28 is moved to the optical disk while the disk ejection mechanism 43 is moving at least. Since the structure has an actuator 29 that is separated from 1, even when the disc ejection mechanism 43 moves over the upper surface of the cover 21A so as to pass through the window 21B, it may accidentally enter the window 21B. Since the objective lens 28 is also retracted by the actuator 29, the objective lens 28 does not interfere with the disc ejection mechanism 43. Therefore, it is possible to avoid disk device failures and malfunctions.
- a slot for inserting and ejecting a disk-shaped recording medium is provided in the apparatus main body, and a rotation driving unit that rotationally drives the disk-shaped recording medium inside the apparatus main body;
- the present invention can be used as a recording medium driving device provided with a pickup mechanism for irradiating light toward a disk-shaped recording medium and a pickup feeding mechanism for moving the pickup mechanism close to and away from the rotation driving unit.
