Description

Conveying device and disk device

Technical field

The present invention relates to a conveying device for conveying a recording medium between an opening through which a disk-shaped recording medium having different diameters can be inserted and a turntable that rotatably holds the recording medium, and a disk Relates to the device.

Background art

Conventionally, in a configuration capable of reading information recorded on a disc-shaped recording medium having different diameters, a configuration for determining the diameter of a recording medium from which this information is read is known (for example, (See Patent Document 1).

In the device described in Patent Document 1, the gain of the amplifier of the spindle servo circuit is set to a gain that can be rotated by a 12 cm CD (Compact Disc), and the servo is turned on. Furthermore, when the CD is rotated at the same rotation speed regardless of the disk diameter and the subcode synchronization signal is detected, the servo is turned off and the acceleration of the spindle motor is started by the acceleration pulse. Then, the timer is started, and when the next subcode synchronization signal is detected, the timer is stopped and the servo is turned on again. After this, when the timer value is longer than the reference time, it is determined that CD is 12 cmCD, and the gain of the amplifier is set to a gain for 12 cmCD. On the other hand, when the timer value is shorter than the reference time, it is determined that CD is 8 cmCD, and the gain for 8 cmCD is set.

The groove 413D moves forward and backward, and the ejection restricting pin 431A is engaged with the large diameter disc ejection restricting groove 424F1 or the small diameter disc eject restricting groove 424F2.

[0039] Further, the slide stopper 424 includes a base end portion of the restriction stopper 424C, which is located on the back surface 10D side of the apparatus main body 10 and intersects the moving direction of the slide stopper 424, specifically Is provided with a large-diameter disk relief portion 424G1 as a relief portion that inclines in a step shape away from the turntable 23. Further, the slide stopper 424 is positioned on the front side 1 OA side of the main body 10 opposite to the large-diameter disk escape portion 424G1 at the base end of the restriction stopper 424C, with respect to the moving direction of the slide stopper 424. In the direction intersecting with each other, more specifically in the direction away from the turntable 23, a small-diameter disk relief groove 424G2 is provided as a concave groove-like relief portion. The clearance 424G1 for large-diameter discs and the clearance groove 424G2 for small-diameter discs engage with the arm restricting pin 414A of the 8cm arm 414 to provide clearance between the guide lever 411 of the disc guide mechanism 41 and the optical disc 1. The disc guide mechanism 41 is moved to the reserved state.

[0040] Further, the slide stopper 424 is provided with a positioning restriction piece 424H that protrudes toward the back surface 10D of the apparatus main body 10 and that has its tip end bent upward (front side in FIG. 1).

Connect and separate. In this contact / separation state, when the engagement protrusion 423C of the link arm 423 contacts the inclined contact portion 424A of the slide stopper 424 and the slide stopper 424 slides toward the right wall 10C, the leaf spring member 417 is elastically deformed. When the engagement protrusion 423C of the link arm 423 moves to the rear surface 10D side and the third engagement recess 424B force of the slide stud 424 is also released, the slide stop is caused by the restoring force due to the elastic deformation of the leaf spring member 417. No. 424 has been moved to the left wall 10B side and is in a state of being located at the steady position shown in FIG.

The disc ejection mechanism 43 is a mechanism for ejecting the optical disc 1 by pushing it into the slot 11.

The disc ejection mechanism 43 includes an assist arm 431 and an eject arm 432.

[0042] As described above, the assist arm 431 is provided with the pivot regulating pin 431A that is provided on the right wall 10C side of the bridge plate 413 so as to rotate and engages with the assist regulating groove 413B. Thereby, the rotation range of the assist arm 431 is regulated in the assist regulation groove 413B. In addition, as described above, the ejection regulating pin 431 A is inserted into the ejection regulating window 424F via the assist regulating groove 413D of the bridge plate 413, and slides. When the Stutno 424 moves and engages with the large-diameter disc ejection regulating groove 424F1 or the small-diameter disc ejection regulating groove 424F2, the rotation of the assist arm 431 is regulated. In other words, the eject restricting pin 431A is in a state where the tongue-like portion located between the eject restricting groove 424F1 for the large diameter disc and the eject restricting groove 424F2 for the small diameter disc closes a part of the assist restricting groove 413D of the bridge plate 413. By advancing and retracting, it is engaged with the ejection regulating groove for large diameter disc 424F1 or the ejection regulating groove for small diameter disc 424F2. Furthermore, a gear 431B is formed at one end of the assist arm 431 on the left wall 10B side. The assist arm 431 is urged counterclockwise by an urging member (not shown), that is, the gear 431B is urged toward the front 10A in the direction of the force. In addition, the tongue 431C is formed with a tongue-like detection piece 431C in a state in which the rotation center force protrudes outward.

[0043] As described above, the eject arm 432 is rotatably provided on the bridge plate 413. The ejector arm 432 is disposed on the top surface side of the bridge plate 413 and the gear portion 432A serving as a gear positioned on the bottom surface side of the bridge plate 413. And a longitudinal arm portion 432B which is positioned. The gear portion 432A meshes with the gear 431B of the assist arm 431, and is urged clockwise by the urging force of the assist arm 431. This urging force urges the arm portion 432B in the clockwise direction, that is, in the direction of pushing the optical disc 1 into the slot 11. In addition, a roller-shaped contact portion 432C that contacts the periphery of the optical disc 1 is provided at the tip of the arm portion 432B. Further, an arm control protrusion 432D is formed on the opposite side of the pivot portion of the eject arm 432 from the arm portion 432B. The arm control protrusion 432D comes into contact with the side edge of the 8cm arm 414 when the eject arm 432 rotates.

Each of the first drive cam 44 and the second drive cam 45 has an engagement groove (not shown), and these engagement grooves are formed on the two side surfaces of the base portion 21. The cam projections (not shown) are respectively engaged. The first drive cam 44 and the second drive cam 45 are formed in a substantially long shape, and are advanced and retracted along the longitudinal direction by a motor and a gear mechanism (not shown). As a result, the pedestal 21 is swung so as to be close to and away from the recording surface of the optical disc 1 mounted on the turntable 23. [0045] The link arm 423, the first drive cam 44, and the lever reduce the amount of the optical disc 1 sent to the turntable 23 when the optical disc 1 is a large-diameter disc 1A, and the optical disc 1 becomes a small-diameter disc 1B. In this case, a disc feeding cam portion 51 is provided to increase the feeding amount of the optical disc 1 to be sent to the turntable 23.

The disc feeding cam portion 51 includes a protrusion 52 provided on the link arm 423, and a cam groove 53 that is engaged with the protrusion 52 and formed in the first drive cam 44. Yes.

And a common cam groove 53C joined at one end with 53B. The first cam groove 53A and the second cam groove 53B are formed to extend in the moving direction of the first drive cam 44, respectively.

[0048] The second drive cam 45 is connected to the first drive cam 44, and moves forward and backward in the left-right direction in conjunction with the forward and backward movement of the first drive cam 44. On the first drive cam 44 side of the second drive cam 45, as shown in FIG. 3, there is provided a force projection 45A that projects in a rectangular shape in plan view in the direction of the back surface 10D. Then, when a sensor (not shown) detects that the center of the optical disk 1 is located on the turntable 23, the first drive cam 44 moves to the rear surface 10D side, and the second drive cam 45 moves to the left wall 10B side. Move to. Due to the movement of the second drive cam 45, the pedestal portion 21 comes close to the recording surface of the optical disc 1, and the optical disc 1 is clamped with respect to the turntable 23. In this state, the turntable 23 rotates and information is recorded on the optical disc 1 or information recorded on the optical disc 1 is reproduced.

Further, as shown in FIGS. 1 and 3, a clamp detection switch 47 as a holding detection unit is provided in the vicinity of the second drive cam 45 in the control circuit unit. The clamp detection switch 47 includes a thin square box-like switch base 47A, and an advance / retreat member 47B that advances and retreats by contact of the cam protrusion 45A of the second drive cam 45 on one side surface of the switch base 47A. Yes. As shown by the imaginary line (two-dot chain line) in FIG. 3, the advancing / retracting member 47B moves when the second driving force drum 45 moves to the left wall 10B side and the optical disc 1 is clamped to clamp the cam projection 45A. Pressed by contact to turn on. Also, as shown by the solid line in FIG. 3, when the second drive cam 45 moves to the right wall 10C side and the clamp of the optical disc 1 is released, the cam protrusion 45A is released from the contact and pressed. It will be turned off. The control circuit unit appropriately controls the operation of the disk device 100 as described above. Further, when the eject detection button is pressed while the clamp detection switch 47 is on, that is, when the optical disc 1 is clamped, the control circuit section recognizes the on-state of the arm position detection switch 46. When it is recognized that the arm position detection switch 46 is in the ON state, it is determined that the large-diameter disk 1A is clamped, and the operation of each member is controlled so that the large-diameter disk 1A is ejected. Further, when it is recognized that the arm position detection switch 46 is in the OFF state, it is determined that the small-diameter disk 1B is clamped, and the operation of each member is controlled so that the small-diameter disk 1B is ejected.

[0051] Further, as shown in FIG. 1, a first switch 48A, which is a detection switch similar to the arm position detection switch 46 and the clamp detection switch 47, is arranged near the slide stopper 424 in the control circuit section. It is installed. In this first switch 48A, the engagement protrusion 423C of the link arm 423 that rotates together with the load arm 421 moves to the front 10A side and comes into contact with the inclined contact portion 424A of the slide stopper 424, and the slide stock 424 moves to the right. When it slides to the wall 10C side, it turns on. In addition, the first switch 48A has the engagement protrusion 423C of the link arm 423 moved to the rear surface 10D side, and the third engagement recess 424B of the slide stopper 424 is also released, and the restoring force of the plate spring member 417 is in the steady position. When the slide stopper 424 is moved to, it is turned off.

Furthermore, in the vicinity of the assist arm 431 in the control circuit section, as shown in FIG. 1, a second switch 48B and a detection switch which are detection switches similar to the arm position detection switch 46 and the clamp detection switch 47 are provided. A third switch 48C is provided. The second switch 48B is located in the vicinity of the tip of the detection piece 431C of the assist arm 431. When the eject arm 432 is at the initial position shown in FIG. When the assist arm 431 is rotated by being carried to the position where it is inserted and held by the turntable 23 and rotated, the assist arm 431 is disposed at a position where it is turned off. The third switch 48C is positioned near the base end of the detection piece 431C of the assist arm 431, and is held in the turntable 23 in the off state when the eject arm 432 is in the initial position shown in FIG. When the assist arm 431 is turned by turning the eject arm 432 that contacts the small-diameter disc 1B from the turning state to the back side 10D, It is arranged at the position. The first switch 48A, the second switch 48B, and the third switch 48C are mounted at predetermined positions, the transport motor 31, the first drive cam 44 and the second drive cam 45, Thus, the operation unit of the present invention is configured.

[0054] (Detection of large diameter disk)

First, the operation of the disk device when detecting the clamp of the large-diameter disk 1A having a disk diameter of 12 cm inserted into the disk device 100 in the initial state as shown in FIG. In the initial state shown in FIG. 1, since the load arm 421 is not rotated and is in the standby position, the slide stopper 424 is not moved and is set in the standby position by the leaf spring member 417, and the first switch 48A is in the OFF state. It is. Further, since the eject arm 432 is also in the standby position where it does not rotate, the second switch 48B is kept in the on state and the third switch 48C is kept in the off state. For this reason, the control circuit unit recognizes these states, determines that the optical disk 1 in “mode 1” is in the initial standby state where no optical disk 1 is inserted, and waits for insertion of the optical disk 1 as shown in FIG. It becomes a state. [0055] Then, when the large-diameter disk 1A is inserted from the slot 11 of the disk device 100 in the initial standby state shown in FIG. 1, the peripheral portion of the large-diameter disk 1A moves the contact portion 42 1A of the load arm 421 to the right. Push to wall 10C and rotate. As a result, the link arm 423 rotates counterclockwise, and the slide stopper 424 slides toward the right wall 10C against the elastic force of the leaf spring member 417. This movement of the slide stopper 424 releases the restriction stopper 424C from the arm restriction groove 413A of the bridge plate 413, thereby releasing the restriction of the rotation range of the 8cm arm 414, and ejecting restriction groove 424F1 for the large diameter disk and the small diameter disk. The tongue-shaped portion located between the eject control groove 424F2 is the assist control groove 413D of the bridge plate 413 and the 413D force is released, so that the restriction of the rotation range of the assist arm 431 is released and the rotation restriction of the eject arm 432 is released. Is done. Further, when the slide stopper 424 slides toward the right wall 10C, the first switch 48A is also turned on, and the control circuit section recognizes the on state of the first switch 48A. In this state, the eject arm 432 is in a state in which the large-diameter disk 1A is not in contact and does not rotate, so that the second switch 48B is on and the third switch 48C is off. The control circuit section also recognizes this state. That is, as shown in FIG. 12, the control circuit unit determines that it is in a “mode 2” standby state and waits for operation control.

[0056] In this state, when the large-diameter disk 1A is further pushed in, the side edge of the large-diameter disk 1A comes into contact with the sliding contact surface 412B of the disk guide 412 and the disk guide 412 is moved to the left wall 1OB side. Turn. At this time, the guide lever 411 is also pushed into the back surface 10D side, and the guide pin 411B moves from the inclined groove 415C and the linear groove 415B of the guide guide groove 415 to the arc groove 415A. Then, the guide pin 411B moves to the left wall 10B side along the circular groove 415A, so that the guide lever 411 is maintained in a state substantially parallel to the conveying direction of the large-diameter disk 1A while maintaining the left wall 10B. The guide part 411 A guides the peripheral part of the large-diameter disc 1 A. Further, the movement of the guide pin 411B causes the 8cm arm 414 to rotate in the direction approaching the back surface 10D. When the 8 cm arm 414 rotates, as shown by the solid line in FIG. 4, the contact member 414E pushes the advancing / retracting member 46B of the arm position detecting switch 46, and the arm position detecting switch 46 is turned on. At this time, the rotation restricting pin 411C of the guide portion 411A is engaged with the pin locking groove 416A of the pusharm 416, and the push arm 416 is also rotated to the left wall 10B side. . Further, when the large-diameter disc 1A is pushed in, the side edge of the large-diameter disc 1A comes into contact with the abutting portion 432C of the ejector arm 432 to rotate the eject arm 432. As the eject arm 432 rotates, the assist arm 431 engaged with the gear 431B also rotates.

[0057] After that, as shown in FIG. 5, for example, about half of the large-diameter disk 1A is inserted, so that the arm 421 is urged inward, that is, in the clockwise direction. Move along the rim of 1A. The load arm 421 then pushes the large-diameter disk 1A toward the rear 10D side by the biasing force. In the state shown in FIG. 5, the ejector arm 432 is further rotated, the second switch 48B is turned off, the third switch 48C is turned on, and the control circuit unit is turned off and the second switch 48B is turned off. 3 Switch Recognizes the ON state of 48C. Since the first switch 48A is in the ON state, the control circuit unit determines that the large-diameter disk 1A has been inserted, and drives the transport motor 31 to drive the first drive cam 44 and the second drive as described later. Move the drive cam 45. If more than half of the large-diameter disk 1A is inserted into the apparatus body 10, and further, if more than half of the large-diameter disk 1A passes through the connecting portion of the guide lever 411 and disk guide 412, the leaf spring 411D is Since it is biased inward, the guide lever 411 is inclined so that the front 10A side protrudes inward, and guides the large-diameter disc 1A to the back.

Then, as shown in FIG. 6, when the central force of the large-diameter disc 1 A is moved onto the turntable 23, the disc loading is completed. Then, as shown in FIG. 7, the large-diameter disk 1A is clamped to the turn table 23. To do this, the insertion detection switch (not shown) is pushed by inserting the large-diameter disk 1A, and as described above, the control circuit unit turns on the first switch 48A, the second switch 48B off, and the third switch. 48C recognizes the ON state, and as shown in FIG. 12, the control circuit unit determines that it is in “mode 8”, drives the conveyance motor 31 (see FIG. 1), and the first drive cam 44 Move to the front 10A side. At this time, the protrusion 52 is inserted into the first cam groove 53A of the first drive cam 44, and the position of the load arm 421 is fixed in a state where a clearance is provided between the large-diameter disk 1A. In conjunction with the movement of the first drive cam 44, the second drive cam 45 also moves to the left wall 10B side. Then, the first drive cam 44 and the second drive cam 45 move the pedestal 21 to the top surface side, and the large-diameter disc 1 A force is clamped. [0059] Further, when the second drive cam 45 moves to the left wall 10B side, the slide stopper 424 moves to the left wall 10B side, and an 8 cm margin is added to the large-diameter disk relief 424G1 of the slide stono 424. The arm restricting pin 414A of the track 414 is engaged so as to ride up, the 8cm arm 414 is moved to the back surface 10D side, and the guide lever 411 is moved to the left wall 10B side (see FIG. 1). Further, the push stopper 424E is brought into contact with the presser piece 416B of the push arm 416. As a result, the guide lever 411 is pressed against the left wall 10B side, and a clearance of a predetermined dimension is provided between the large diameter disc 1A. Also, the movement of the slide stopper 424 causes the eject restricting pin 431A of the cache arm 431 to engage with the eject restricting groove 424F1 for the large-diameter disc, and the abutting portion 432C of the eject arm 432 also has a predetermined size between the large-diameter disc 1A. Movement is restricted with legal clearance. Further, when the second drive cam 45 moves to the left wall 10B side, as shown by the imaginary line in FIG. 3, the clamp detection switch 47 is turned on by pushing the advancement / retraction member 47B of the cam projection 45A force clamp detection switch 47. Switch to the state. Then, the control circuit section recognizes the ON state of the arm position detection switch 46 and the ON state of the clamp detection switch 47, and detects that the large-diameter disk 1A force S has been clamped.

[0060] Thereafter, when the operator presses the eject button, for example, the disk device 100 causes the large-diameter disk 1 A to be turned on and off by the on / off state of the arm position detection switch 46 and the clamp detection switch 47 in the control circuit unit. Since it is judged that the force S is clamped, the discharge process of the large-diameter disk 1A is started immediately.

[0061] (Detection of small diameter disk)

Next, the operation of the disk device when detecting the clamp of the small-diameter disk IB having a disk diameter of 8 cm inserted into the disk apparatus 100 in the initial state as shown in FIG. When the small-diameter disk 1B is inserted from the slot 11 of the disk device 100 in which the control circuit section determines “mode 1” in the initial state shown in FIG. 1, the peripheral edge of the small-diameter disk 1B is loaded as shown in FIG. The abutting portion 421A of the arm 421 abuts against the disc guide 412, and the abutting portion 421A is pushed in the state where the peripheral edge of the small-diameter disc 1B slides to rotate to the left wall 10B side. At this time, the guide lever 411 is also pushed into the back 10D side, and the guide pin 411 B moves from the inclined groove 415C of the guide guide groove 415 to the linear groove 415B. The Note that if the small-diameter disk IB is pushed in and inserted, the peripheral portion pushes the abutting portion 421A of the load arm 421 somewhat toward the right wall 10C and turns it. For this reason, the first switch 48A in which the link arm 423 does not rotate counterclockwise and the slide stopper 424 slides to the right wall 10C side is maintained in the OFF state, and the control circuit section is in the first switch 48A. Recognize off. When the peripheral edge on the right side of the small-diameter disc 1B is inserted to the rear surface 10D side with respect to the contact portion 421A of the load arm 421, the load arm 421 rotates inward to push the small-diameter disc 1B to the center position. I'm going into. Further, in the case where a positional force with the small-diameter disc 1B shifted toward the left wall 10B is also inserted, the small-diameter disc 1B is guided and inserted to the center position along the sliding contact surface 412B of the disc guide 412 (FIG. 1). reference).

[0062] When the right end portion of the small-diameter disc 1B moves to the back surface 10D side from the contact portion 421A of the load arm 421, the small-diameter disc 1B is sent out to the back surface 1 OD side by the urging force of the load arm 421. . At this time, since the guide pin 411 B is engaged with the straight groove 415B, the guide lever 411 has a distance from the guide portion 411 A of the guide lever 411 to the center position of the turntable 23. It almost matches. Therefore, the small-diameter disc 1B pushed by the load arm 421 is conveyed above the turntable 23 along the guide portion 411A of the guide lever 411. At this time, since the guide lever 411 is located away from the left wall 10B, the 8cm arm 414 is located away from the back surface 10D force. For this reason, as shown by the solid line in FIG. 8, the contact member 414E is not pushed against the advance / retreat member 46B of the arm position detection switch 46, and the arm position detection switch 46 is maintained in the OFF state.

[0063] After that, for example, as shown in FIG. 9, when about half of the small-diameter disc 1B is inserted, the load arm 421 is biased inward, that is, clockwise, so that the load arm 421 is almost rotated. The state in which the engagement protrusion 423C of the link arm 423 engages with the third engagement recess 424B of the slide stock 424 is maintained, and the slide stock bar 424 does not move. As a result, a part of the arm restricting groove 413A of the bridge plate 413 is blocked by the restricting stopper 424C of the slide stopper 424, and located between the large diameter disc eject restricting groove 424F1 and the small diameter disc eject restricting groove 424F2. The tongue-shaped part is a bridge A part of the assist regulating groove 413D of the plate 413 is closed, and the moving groove 424F3 is maintained in communication with the small-diameter disc ejection regulating groove 424F2. As a result, the rotational ranges of both the 8 cm arm 414 and the eject arm 432 are restricted. Since the slide stopper 424 is not moved to the right wall 10C side, the first switch 48A is maintained in the off state, and the control circuit unit recognizes the off state of the first switch 48A.

[0064] Then, it is guided between the guide lever 411 and the load arm 421 whose rotation is restricted by the movement restriction of the 8cm arm 414, and, for example, about half of the small-diameter disc 1B is inserted as shown in FIG. Since the load arm 421 is urged inward, that is, clockwise, the small-diameter disc 1B is also pushed into the rear 10D side by the front 10A force. When the small-diameter disc 1B is transported to the state where the center portion is located on the turntable 23 by this pushing, it is not transported further back by the eject arm 432 restricted in rotation, and the center is surely centered on the turntable 23. The part is located and the disk loading is complete. Then, as shown in FIG. 10, the small-diameter disk 1B is clamped to the turntable 23.

Further, when the second drive cam 45 moves to the left wall 10B side, the clamp detection switch 47 is turned on as in the case of clamping the large-diameter disk 1A. The control circuit section recognizes the OFF state of the arm position detection switch 46 and the ON state of the clamp detection switch 47, and detects that the small-diameter disk 1B has been clamped.

[0066] After that, when the operator presses the eject button, for example, the disk device 100 causes the small-diameter disk 1B to be turned on by the arm position detection switch 46 and the clamp detection switch 47 in the control circuit section. Since it is determined that the disk is clamped, the discharge process of the small-diameter disk 1B is started immediately.

The amount of displacement up to the distance can be minimized. That is, the amount of change in the contact state between the contact member 414E and the advance / retreat member 46B can be minimized. Therefore, the diameter dimension discrimination process can be performed with high accuracy.

The movement of the member can be controlled immediately. Therefore, even if the user switches the optical disk 1 immediately after switching the power off and on, for example, the diameter dimension of the optical disk 1 based on the on / off state of the arm position detection switch 46 immediately after the power is turned on. And the discharge operation corresponding to the diameter can be started immediately.
