Description

  The present invention relates to a disk device having a slot-in type transport mechanism.

In a disk apparatus that records or reproduces information using a disk (disk-shaped recording medium) such as a CD (Compact Disc), a DVD (Digital Versatile Disk), or a BD (Blu-ray Disc), a conveyance called a slot-in method is performed. There is a disk device having a mechanism. The slot-in system is a disk transport system in which transport of a disk is automatically started by directly inserting the disk into a slot installed on the front surface of the disk device.
In the case of a slot-in type disk device, when a part of the disk is inserted into the slot, the loading start position where the disk starts to be loaded, and when the disk protrudes from the slot, the disk stops taking out. As the position is as far as possible from the slot, the operability is improved. However, the further away the disk is removed from the slot, the more likely the disk will drop from the slot and cause damage to the disk.

  Patent Document 1 discloses a slot-in type vertical disk device that prevents the disk from dropping from the slot when the disk is unloaded. The disk device of Patent Document 1 includes a pair of upper and lower guide rollers that are fixed integrally with a vertical roller shaft and bias the disk. When the disk rolls obliquely downward and falls, the movement amount of the disk with respect to the upper guide roller becomes larger than the movement amount with respect to the lower guide roller. However, since the pair of upper and lower guide rollers are integrally formed by the roller shaft, the disk biased by the guide roller is prevented from moving and the disk is held.

Is carried in.

As shown in FIG. 4, the link arms 63 </ b> L and 63 </ b> R are flat members that rotate the other front arm in the opposite direction based on the rotation of the one front arm.
The link arms 63L and 63R are arranged so as to cross each other at substantially the center. The link arm 63R is located closer to the bracket 61 than the link arm 63L. At the ends of the link arms 63L and 63R on the carry-in direction side, substantially circular holes are formed, and the link arms 63L and 63R are screwed to the bracket 61 by screws and nuts that pass through these holes. .
A protrusion 63L1 is formed on the side of the link arm 63L facing the bracket 61 at the approximate center. The protrusion 63L1 is slidably fitted in a substantially arc-shaped guide hole 63R1 formed in the approximate center of the link arm 63R. The link arms 63L and 63R constitute a link mechanism in which the movement and position are uniquely determined by the protrusion 63L1 sliding on the guide hole 63R1.
Protrusions 63L2 and 63R2 are formed on the opposite side of the side facing the bracket 61 at the end of the link arms 63L and 63R on the carry-out direction side. The protrusions 63L2 and 63R2 are loosely fitted in the guide hole 62L3 of the front arm 62L and the guide hole 62R2 of the front arm 62R, respectively, and can slide. Thereby, the rotation operation of the link arms 63L and 63R corresponds to the operation of the front arms 62L and 62R.

The detection arm 64 is a flat plate-like member having a substantially fan shape, and the front arm 62 </ b> L is arranged on the side facing the bracket 61. A substantially circular opening 641 is formed in the vicinity of the fan-shaped center of the detection arm 64. The projection 66L1 of the lock arm 66L is inserted into the opening 641. The detection arm 64 is rotatable with respect to the bracket 61.
A substantially cylindrical detection lever 642 is located at a position overlapping the guide hole 616 of the bracket 61 and the guide hole 62L2 of the front arm 62L from the detection arm 64 in the direction facing the bracket 61 and in the opposite direction. It protrudes so as to pass through the hole 62L2. The detection lever 642 is urged toward the unloading direction by a torsion spring (not shown). The detection lever 642 presses the first switch 16, the second switch 17, and the third switch 18 that detect the position of the disk 2 while sliding along the guide hole 616 and the guide hole 62 </ b> L <b> 2 as the disk 2 is transported.

The torsion springs 65L and 65R are springs that urge the front arms 62L and 62R and the detection arm 64 toward the carry-out direction. Alternatively, the torsion springs 65L and 65R are springs that urge the front arm 62L, the detection arm 64, and the front arm 62R toward each other.
The torsion springs 65L and 65R are inserted and engaged with the projections 66L1 and 66R1 of the lock arms 66L and 66R, respectively, and are locked to the front arms 62L and 62R and the detection arm 64.

Next, the operation of the transport mechanism 6 will be described.
FIG. 6 is an explanatory diagram showing the arrangement of the disk 2, the first switch 16, the second switch 17, and the third switch 18. The on / off state of each switch is switched by being pressed by the detection lever 642. Each switch is arranged in the movement path of the detection lever 642, but the first switch 16 and the third switch 18 are arranged at a position close to the slot 4, and the second switch 17 is arranged at a position far from the slot 4. Further, the first switch 16 is disposed at a position slightly closer to the slot 4 than the third switch 18.

  When the disk 2 is inserted from the slot 4, the disk 2 comes into contact with the first fixed roller 62L4, the second fixed roller 62L5, the first drive roller 62R6, and the second drive roller 62R7 (solid line position in FIG. 6). Further, the disk 2 comes into contact with the detection lever 642. When the insertion of the disk 2 is continued against the urging of the front arms 62L, 62R and the detection lever 642 by the torsion springs 65L, 65R, etc., the detection arm 642 that is pushed by the outer peripheral edge of the disk 2 moves 1 switch 16 is pressed to turn it on (the dashed line position in FIG. 6). The first switch 16 outputs an ON signal to the control unit 11. The control unit 11 that has received the ON signal output from the first switch 16 rotates the roller drive motor 15 in the direction in which the disk 2 is loaded. The first drive roller 62R6 and the second drive roller 62R7 that are rotationally driven by the roller drive motor 15 move the disk 2 in the loading direction. As the disk 2 is carried in, the front arms 62L and 62R rotate in a direction away from each other while synchronizing.

  When the disk 2 is carried in slightly in the carrying-in direction from the one-dot chain line position in FIG. 6, the detection arm 642 pushed by the disk 2 pushes the third switch 18 and turns on the third switch 18.

FIG. 7 is an explanatory diagram showing the arrangement of the disk 2 and the front arms 62L and 62R in the middle of loading. Note that the outer shapes of the front arms 62L and 62R in FIG. 7 are drawn in more detail than the outer shapes of the front arms 62L and 62R that are simplified in FIG.
When the loading of the disk 2 is continued, the disk 2 is separated from the first fixed roller 62L4 and the first driving roller 62R6, and the front arms 62L and 62R are rotated approximately 45 degrees in the separating direction or the loading direction, respectively. In this case, the arrangement direction of the first fixed roller 62L4 and the second fixed roller 62L5 and the arrangement direction of the first drive roller 62R6 and the second drive roller 62R7 are substantially the same as the loading direction of the disk 2, respectively.

  Further, when the loading of the disk 2 continues and the disk 2 reaches the dotted line position in FIG. 6, the detection lever 642 presses the second switch 17 to turn it on. The second switch 17 outputs an ON signal to the control unit 11. Upon receiving the ON signal output from the second switch 17, the control unit 11 stops the roller drive motor 15.

When the roller drive motor 15 is stopped, the disk 2 moves from the loading completion position (dotted line position in FIG. 6) to a catching position with a clamper (not shown).
The signal input unit 12 receives an eject signal from the outside of the disk device, and outputs the received eject signal to the control unit 11. The control unit 11 that has received the eject signal output from the signal input unit 12 rotates the roller drive motor 15 in the direction in which the disk 2 is unloaded. Further, the control unit 11 moves the disk 2 from the catching position to the completion of loading. The detection lever 642 pushed by the disc 2 to be carried out pushes the second switch 17. The pressed second switch 17 is switched to the off state.

  The disk 2 is unloaded in the unloading direction, and the front arms 62L and 62R rotate in the approaching direction or unloading direction. When the detection lever 642 presses the third switch 18 as the disc 2 is unloaded, the third switch 18 is turned off and an off signal is output to the control unit 11. The control unit 11 that has received the OFF signal output from the third switch 18 stops the roller drive motor 15. At this time, the disk 2 has been unloaded to the take-out position (the two-dot chain line position in FIG. 6).

  FIG. 8 is an explanatory diagram showing the rotation of the first drive roller 62R6 and the second drive roller 62R7 at the disk 2 take-out position. The first drive roller 62R6 and the second drive roller 62R7 rotate in the direction in which the disk 2 is unloaded by the rotation of the roller drive motor 15, and unload the disk 2 to the take-out position (FIG. 8A). The control of the control unit 11 that has received the OFF signal output from the third switch 18 stops the roller drive motor 15 and stops the rotation of the first drive roller 62R6 and the second drive roller 62R7 (FIG. 8B). ). Further, when the control unit 11 receives the OFF signal output from the third switch 18, the control unit 11 causes the timer 14 to start measuring the standby time. The standby time is the time from when the control unit 11 receives the OFF signal output from the third switch 18 until the roller drive motor 15 is continuously rotated in the direction in which the disk 2 is loaded.

  At the take-out position of the disk 2, the disk 2 is in contact with the first fixed roller 62L4, the second fixed roller 62L5, the first drive roller 62R6 and the second drive roller 62R7, and from the slot 4 to the housing 3 It is also in contact with the felt 4a installed inside. Since the front arms 62L and 62R are urged in the unloading direction by the urging forces of the torsion springs 65L and 65R, the disk 2 is forced to be pushed in the unloading direction by the first fixed roller 62L4, the second fixed roller 62L5, Received from the first drive roller 62R6 and the second drive roller 62R7. However, since the friction force with the felt 4a also acts on the disc 2, the disc 2 is held at the take-out position. However, there is a risk that the disk 2 falls from the slot 4 due to vibration, gravity, or the like from the outside of the disk device 1.

After stopping the roller drive motor 15, the control unit 11 causes the roller drive motor 15 to start the rotation that repeats intermittent rotation at predetermined time intervals in the direction in which the disk 2 is loaded (FIG. 8C )). However, the control unit 11 controls the rotation speed of the roller drive motor 15 to be lower than the rotation speed when the disk 2 is loaded.
When the rotational speed of the roller drive motor 15 is too high, the disk 2 is carried into the disk device 1 again by driving the first drive roller 62R6 and the second drive roller 62R7. On the other hand, when the rotational speed of the roller drive motor 15 is too low, the disk 2 is not held. Therefore, by appropriately reducing the rotational speed of the roller drive motor 15, the urging forces of the torsion springs 65L and 65R and the force for loading the disk 2 are balanced, and the disk 2 can be held at the take-out position.

Intermittently rotating the roller drive motor 15 also has an effect of holding the disk 2 in the take-out position. Even if the loading of the disk 2 is about to start, the disk 2 can be returned to the take-out position by the urging force of the torsion springs 65L and 65R by intermittently stopping the rotation of the roller drive motor 15. .
In addition, by intermittently rotating the roller drive motor 15, the user can be alerted from the rotational sound of the roller drive motor 15, minute vibrations of the disk 2, etc. Therefore, it becomes easy to take out the disk 2. That is, the operability of the disk device 1 is improved.

When the disk drive 2 is ejected while the roller drive motor 15 repeats intermittent rotation at the ejection position of the disc 2, the detection lever 642 presses the first switch 16 by the movement of the disc 2 in the carry-out direction. The first switch 16 is turned off. The first switch 16 outputs an off signal to the control unit 11. The control unit 11 that has received the OFF signal output from the first switch 16 stops the roller drive motor 15.
When the roller drive motor 15 repeats intermittent rotation at the disk 2 take-out position and the disk 2 is not taken out, the timer 14 outputs a signal indicating the end of the standby time to the control unit 11. The control unit 11 that has received a signal indicating the end of the standby time from the timer 14 changes the rotation of the roller drive motor 15 from intermittent rotation to continuous rotation, and changes the rotation speed of the roller drive motor 15 of the disk 2. The speed is controlled to the same speed as the loading speed. That is, the control unit 11 controls the rotation of the roller drive motor 15 to be the same as the rotation at the time of loading the disk 2.

  When the control unit 11 receives an off signal output from the third switch 18 instead of notifying the control unit 11 of the end of the standby time by a signal from the timer 14, the control unit 11 turns off the storage unit 13. The form which memorize | stores the time which received the signal may be sufficient. The control unit 11 reads the time periodically stored in the storage unit 13 while receiving a signal at regular time intervals from the timer 14, and determines that the standby time has elapsed, the rotation of the roller drive motor 15 is changed to the disk 2. The form may be controlled so as to be the same as that at the time of loading.

  After the waiting time elapses, the roller drive motor 15 is continuously rotated at the same direction and the same rotational speed as when the disk 2 is loaded, so that the disk 2 starts to be loaded via the first drive roller 62R6 and the second drive roller 62R7. . Accordingly, when the disk 2 is not ejected from the ejection position even after the standby time has elapsed, the disk 2 can be reliably protected by being carried into the disk device 1.

  Note that the rotational speed of the roller drive motor 15 after the standby time has elapsed is not limited to the same rotational speed as when the disk 2 is loaded, and any rotational speed may be used as long as the disk 2 can be loaded. .

  When the loading of the disk 2 continues and the detection lever 642 presses the second switch 17, the second switch 17 outputs an ON signal to the control unit 11. Upon receiving the ON signal output from the second switch 17, the control unit 11 stops the roller drive motor 15.

FIG. 9 is a transition diagram showing the states of the roller drive motor 15, the first switch 16, the second switch 17, and the third switch 18. With reference to FIG. 9, the movement of the transport mechanism 6 during the transport of the disk 2 will be described.
When the disk 2 is inserted from the slot 4 and the detection lever 642 turns on the first switch 16, the control unit 11 rotates the roller drive motor 15 in the direction in which the disk 2 is loaded. When the loading of the disk 2 continues, the detection lever 642 turns on the third switch 18. When the detection lever 642 turns on the second switch 17, the second switch 17 outputs an on signal to the control unit 11. The controller 11 that has received the ON signal output from the second switch stops the roller drive motor 15. At this time, the loading of the disk 2 of the transport mechanism 6 is completed.

  When the control unit 11 receives the eject signal output from the signal input unit 12, the control unit 11 rotates the roller drive motor 15 in the direction in which the disk 2 is carried out. As the disk 2 is unloaded, the detection lever 642 turns off the second switch. When the disc 2 is carried out to the take-out position and the detection lever 642 turns off the third switch 18, the third switch 18 outputs an off signal to the control unit 11. The control unit 11 that has received the OFF signal output from the third switch 18 stops the roller drive motor 15 and causes the timer 14 to start measuring the standby time. At this point, the unloading of the disk 2 of the transport mechanism 6 is completed.

  The control unit 11 causes the roller drive motor 15 to start rotation that repeats intermittently at predetermined time intervals in the direction in which the disk 2 is loaded. At this time, the rotational speed of the roller drive motor 15 is lower than the rotational speed when the disk 2 is loaded. When the standby time has elapsed, the timer 14 outputs a signal indicating that the standby time has elapsed to the control unit 11. The control unit 11 that has received the signal indicating the elapse of the standby time output from the timer 14 continuously rotates the roller drive motor 15 in the same direction and at the same rotational speed as when the disk 2 is loaded.

  If the detection lever 642 turns off the first switch 16 before the control unit 11 receives the signal indicating the elapse of the standby time output from the timer 14, the first switch 16 outputs an off signal to the control unit 11. To do. The control unit 11 that has received the OFF signal output from the first switch 16 stops the roller drive motor 15.

Next, a process executed by the transport mechanism 6 to control the driving of the roller drive motor 15 when the disk 2 is carried in and out will be described.
FIG. 10 and FIG. 11 are flowcharts showing the procedure of the disk 2 transport process executed by the control unit 11 of the disk device 1.
The control unit 11 determines whether or not the first switch 16 is on (step S1001). When it is determined that the first switch 16 is not in the on state (step S1001: NO), the control unit 11 returns the process to step S1001. When the controller 11 determines that the first switch 16 is in the on state (step S1001: YES), the controller 11 rotates the roller drive motor 15 in the direction in which the disk 2 is loaded (step S1002). Thereby, the disk 2 starts to be carried in. The control unit 11 determines whether or not the second switch 17 is on (step S1003). When it is determined that the second switch 17 is not in the on state (step S1003: NO), the control unit 11 returns the process to step S1003. When the controller 11 determines that the second switch 17 is on (step S1003: YES), the controller 11 stops the roller drive motor 15 (step S1004). Thereby, the loading of the disk 2 by the transport mechanism 6 is completed.

  The control unit 11 determines whether or not the eject signal output from the signal input unit 12 has been received (step S1005). When the control unit 11 determines that the eject signal output from the signal input unit 12 is not received (step S1005: NO), the control unit 11 returns the process to step S1005. When it is determined that the eject signal output from the signal input unit 12 has been received (step S1005: YES), the control unit 11 rotates the roller drive motor 15 in the direction in which the disk 2 is carried out (step S1006). Thereby, the disk 2 starts to be carried out. The control unit 11 determines whether or not the third switch 18 is in an off state (step S1007). When it is determined that the third switch 18 is not in the off state (step S1007: NO), the control unit 11 returns the process to step S1007. When it is determined that the third switch 18 is in the OFF state (step S1007: YES), the controller 11 stops the roller drive motor 15 (step S1008). The control unit 11 causes the timer 14 to start measuring time (step S1009), and intermittently rotates the roller drive motor 15 in the direction in which the disk 2 is loaded (step S1010). Further, the control unit 11 makes the rotation speed of the roller drive motor 15 here lower than the rotation speed of the roller drive motor 15 in step S1002.

The control unit 11 determines whether or not a signal indicating that the standby time has elapsed has been received from the timer 14 (step S1011). When it is determined that the signal indicating the elapse of the standby time has been received from the timer 14 (step S1011: YES), the control unit 11 returns the process to step S1002. In step S1002, the control unit 11 increases the rotational speed of the roller drive motor 15 higher than the rotational speed of the roller drive motor 15 in step S1010.
When it is determined that the signal indicating the elapse of the standby time has not been received from the timer 14 (step S1011: NO), the control unit 11 determines whether or not the first switch 16 is in an off state (step S1012). When it is determined that the first switch 16 is not in the off state (step S1012: NO), the control unit 11 returns the process to step S1011. When the controller 11 determines that the first switch 16 is in the OFF state (step S1012: YES), the controller 11 stops the roller drive motor 15 (step S1013), and ends the process.

When the disc 2 is carried out to the take-out position of the disc device 1, the disc 2 in the take-out position is held by a frictional force with the felt 4 a installed inside the slot 4. However, since the thickness of the disk 2 varies due to manufacturing or the like, in the case of the thin disk 2, the force that the felt 4a holds the disk 2 at the take-out position becomes weak. Further, since the felt 4a is worn by repeated contact with the disk 2, even if the thickness of the disk 2 is a regular thickness, the holding force of the disk 2 by the felt 4a decreases with time.
According to the disk device 1 of the present embodiment, even if the disk 2 is thin or the felt 4a is worn, the first drive roller 62R6 and the second drive that contact the outer peripheral edge of the disk 2 at the take-out position. By rotating the roller 62R7 in the direction in which the disk 2 is loaded, the disk 2 can be reliably held at the removal position. Thereby, the fall of the disk 2 can be prevented and the damage of the disk 2 can be prevented. Further, by intermittently rotating the first drive roller 62R6 and the second drive roller 62R7 and keeping the rotation speed lower than the rotation speed when the disk 2 is loaded, the disk 2 is removed without being loaded. Holding in position continues. That is, the urging force by the torsion springs 65L and 65R balances with the carry-in input by the first drive roller 62R6 and the second drive roller 62R7, and the disk 2 can be kept stationary without dropping at the take-out position.
Further, the frictional force acting between the felt 4a and the disk 2 acts in the carry-in direction or the carry-out direction so as to prevent the disk 2 from moving. Therefore, the friction force by the felt 4a is added to the balance of the above forces, so that the disc 2 is held more stably at the take-out position.

  According to the disk device 1 of the present embodiment, when the disk 2 is held at the take-out position, the first drive roller 62R6 and the second drive roller 62R7 do not contact the recording surface of the disk 2, and therefore the recording surface of the disk 2 Will not hurt.

  According to the disk device 1 of the present embodiment, since the existing components are used to hold the disk 2 at the take-out position, it is not necessary to add new components, and the number of components can be increased. The apparatus 1 is not complicated and large.

  In the present embodiment, a slot-in type disk device related to a driving roller having a rotating shaft substantially perpendicular to the disk surface and driven in contact with the outer peripheral edge of the disk is handled. However, the disk device according to the present invention may be a slot-in type disk device having a rotating shaft parallel to the disk surface and a pair of drive rollers that convey the disk across the disk surface. In such a case, the disk can be held at the take-out position by rotating the pair of drive rollers that sandwich the disk in the direction of loading the disk.

In the present embodiment, the disk is held at the take-out position by inverting the roller drive motor in the direction in which the disk is carried in with respect to the disk carried to the disk take-out position. However, the rotation direction of the roller drive motor may always be the same direction. By installing a gear that reverses rotation in the drive transmission mechanism that transmits the driving force of the roller drive motor to the drive roller, the rotation of the drive roller that conveys the disk is reversed without changing the rotation direction of the roller drive motor. Because it can.
Further, intermittent rotation of the drive roller is also possible by switching gears. Further, the rotational speed of the drive roller can be easily changed by appropriately switching the diameter size and the number of teeth of the gear to be engaged. Therefore, in order to control the rotation of the driving roller, a control unit that takes into account a gear switching unit in addition to the control unit that controls the roller driving motor may be employed.

In this embodiment, the driving force of the disk is adjusted by changing the rotational speed of the driving roller. However, the drive force of the disk may be adjusted by changing the torque of the drive roller. In other words, the disk device may include control means characterized in that the forward rotation torque of the drive roller is made smaller than the forward rotation torque when the disk is loaded. This is possible by controlling the torque of the roller drive motor. Similarly, the disk device may include a control unit characterized in that when a signal indicating the passage of the standby time is received, the forward rotation torque of the drive roller is increased.
Thereby, the disc can be held at the take-out position. In addition, when the standby time has elapsed, the disk can be carried into the housing of the disk device to protect the disk.

  A specific implementation target device of the disk device of the present embodiment is a disk device built in a television, a DVD recorder, a BD recorder, a PC (Personal Computer), or the like. Further, the disk device may be separable from these devices. Further, the disk device may be distributed as a single unit.

  The present embodiment is merely an example of the implementation of the present invention, and the technical scope of the present invention should not be construed in a limited manner. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.
