[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a disk device employing a loading system, and more particularly to a disk device that can reliably perform a disk insertion operation and a re-loading operation after ejection.
[0002]
[Prior art]
Some of the conventional in-vehicle disk devices are provided with a guide member for sandwiching the edge of the disk and a conveying means, and a conveying force is applied to the disk from the conveying means.
[0003]
In this type of disk device, when the disk is inserted from the entrance / exit, one edge of the disk is guided by the guide member, and the other edge of the disk is supplied with a conveying force from the conveying means. One edge is transferred while rolling along the guide member.
[0004]
In the disk device using the guide member and the conveying means, a conventional conveying roller that sandwiches the disk from above and below in the thickness direction and exhibits a conveying force becomes unnecessary, and after the loading of the disk is completed, the conveying roller is replaced with the disk. It is not necessary to perform a retraction operation in a direction away from the surface, and the mechanism is simplified and the thickness can be reduced.
[0005]
In addition, since there is no transport roller facing the surface of the disk that has been loaded, the disk that has been loaded into a predetermined position by the guide member and the transport means is moved in the thickness direction of the disk as it is, and a plurality of sheets are loaded in the apparatus. It is easy to realize a structure in which the discs are stocked so as to overlap each other in the thickness direction, or one of the discs is selected by moving the disc in the apparatus in the thickness direction and the selected disc is driven.
[0006]
[Problems to be solved by the invention]
However, the mechanism for holding the edge of the disk between the guide member and the conveying means and transporting the disk has the following problems.
[0007]
(1) When the disc is inserted from the entrance / exit, if the disc is not surely pushed between the guide member and the conveying means, a reliable carrying input may not be given to the disc. That is, when the disc is inserted from the entrance / exit, if the center of the disc is not pushed to a position where the guide member and the transport means face each other, the disc is not securely clamped by the guide member and the transport means, and the loading direction into the disc There is a case that the power of can not be given reliably.
[0008]
(2) In the in-vehicle disc device, after the disc is ejected from the entrance / exit, when the disc exists at the entrance / exit for a certain period of time, an operation of re-injecting the disc into the device is performed. At this time, the disc stopped at the position ejected to the entrance / exit cannot be securely held between the guide member and the transport device, and the disc may not be carried in.
[0009]
(3) When the disc is ejected, the ejecting force to the disc is interrupted when the center of the disc reaches the unloading side end portion of the guide member and the conveying means. Therefore, the protruding dimension from the entrance / exit of the disc that has been ejected is shortened, and the disc protruding from the entrance / exit is gripped by hand and is difficult to retract.
[0010]

The cross-sectional shape of the long groove 8A is a V shape that is wide on the opening end side on the X1 side in the drawing and narrow on the X2 side.
[0025]
A detection arm (detection member) 24 is provided at an end of the guide member 8 on the discharge side (Y2 side). The detection arm 24 is supported so as to be able to rotate clockwise and counterclockwise in FIG. 1 about a shaft 24a, and is urged counterclockwise by an urging member (not shown).
[0026]
The detection arm 24 is formed with a detection piece 24b located at the end of the guide member 8 on the discharge side. When the detection piece 24b is pushed outward (X2 direction) by the outer peripheral edge of the disk D moving in the long groove 8A of the guide member 8, the detection arm 24 rotates clockwise.
[0027]
At the other end of the detection arm 24, a pressing piece 24c bent downward is formed, and this pressing piece 24c faces the actuator 23a of the first detection switch 23. When the detection arm 24 is rotated in the clockwise direction, the actuator 23a is pressed by the pressing piece 24c, and the first detection switch 23 is switched to the ON state. Further, when the detection arm 24 rotates counterclockwise and the detection piece 24b covers the discharge side (Y2 side) end of the long groove 8A of the guide member 8, the pressing piece 24c is the actuator. The first detection switch 23 is switched to the OFF state away from 23a.
[0028]
On the surface of the second moving member 22, a conveying means 10 including first to fourth carry-in rollers 11, 12, 13, 14 arranged in the insertion direction (Y direction) of the disk D is attached to the guide member 8. It is provided facing. At the top and bottom of the first to fourth carry-in rollers 11, 12, 13, and 14, flanges that gradually decrease in thickness from the center toward the outer periphery are formed. Held between.
[0029]
A conveying motor Md is provided in the apparatus, and the power of the conveying motor Md is decelerated by a gear group and transmitted to each of the carry-in rollers 11, 12, 13, and 14, and the first to fourth carry-in rollers 11, 12, 13, and 14 are all driven to rotate in the same direction. When the first to fourth carry-in rollers 11, 12, 13, and 14 are rotated clockwise, the disk D is loaded in the rear direction of the apparatus (Y1 direction) and rotated counterclockwise. The disk D is carried out in the external direction (Y1 direction).
[0030]
The second moving member 22 is provided with a rotating arm 27 that can rotate within a certain angular range with a support shaft 27 a as a fulcrum, and the first carry-in roller 11 has a tip portion of the rotating arm 27. Is supported rotatably. The rotating arm 27 is always urged clockwise by an urging member (elastic pressing means) 26 such as a tension coil spring.
[0031]
A second detection switch (detection means) 29 is provided on the second moving member 22. A pressing piece 27b is formed on the rotating arm 27, and the first carry-in roller 11 is pushed outward at the edge of the disk D as shown in FIG. When the actuator rotates in the direction, the actuator of the second detection switch 29 is pressed, and the switch output is turned ON.
[0032]
A linear position sensor for detecting the movement position of the first moving member 21 in the X direction is provided in the housing of the disk device 1. The linear position sensor is, for example, a linear variable resistor, and can detect the position of the first moving member 21, and as a result, the facing distance between the guide member 8 and the conveying means 10 can be set.
[0033]
Further, inside the disk device 1, there is provided a control means 40 to which a detection output from the first detection switch 23, the second detection switch 29 and the linear position sensor is given. The operation of the setting motor Mr and the transport motor Md is controlled by the control means 40.
[0034]
Inside the disc apparatus 1 is provided a disc holder that holds the outer peripheral edge of the front of the disc that is sandwiched and carried by the guide member 8 and the conveying means 10. A plurality of disc holders are arranged in the thickness direction of the disc. The disk holder is movable up and down in the thickness direction of the disk, and when any disk holder is at a height that coincides with the conveying path of the guide member 8 and the conveying means 10, the disk is loaded into the disk holder, Further, the disc held by the disc holder at the height is carried out by the guide member 8 and the conveying means 10.
[0035]
Further, when the plurality of disk holders are moved up and down, one of the disks is selected and installed at a position where it can be driven. In the housing, there is provided a disk drive unit 6 having a disk rotation driving means 4 for clamping and rotating the disk D, and a pickup means 5 for reading and writing the disk. Driven by the disk drive unit 6.
[0036]
Next, the operation of the disk device will be described.
In the disk device 1, the connecting gear 41 is driven by the setting motor Mr, so that the first moving member 21 and the second moving member 22 move in the X direction synchronously. As a result, the guide member 8 and the distance between the conveying means 10 on the right end side are set.
[0037]
In a standby state where the insertion of the disk D is awaited, the guide member 8 and the conveying means 10 face each other at an interval narrower than the diameter (8 cm) of the small-diameter disk. When the small-diameter disk is inserted from the entrance / exit 2a, only one of the detection arm 24 and the rotation arm 27 is expanded outward, and only one of the first and second detection switches 23 and 29 is ON. become. At this time, the control means 40 determines that the small-diameter disk has been inserted, the first moving member 21 and the second moving member 22 move to the left and right, and the interval between the guide member 8 and the conveying means 10 conveying the small-diameter disk. The small-diameter disk is carried in by the rotational force of each roller of the conveying means 10. However, the small-diameter disk is not loaded into the position held by the disk holder, but is installed in the disk drive unit 6.
[0038]
When a large-diameter disk having a diameter of 12 cm is inserted, the detection arm 24 and the rotation arm 27 are simultaneously pushed outward and the first and second detection switches 23 and 29 are turned on together. At this time, the control means 40 determines that the large-diameter disk has been inserted, the first moving member 21 and the second moving member 22 move to the left and right, and the guide member 8 and the conveying means 10 convey the large-diameter disk. The interval is set, and the large-diameter disk is carried into a position where it is held by the disk holder by the rotational force of each roller of the conveying means 10.
[0039]
Next, the disk unloading operation will be described. Hereinafter, a case where a large-diameter disk is carried out will be described, but the operation is the same when a small-diameter disk is carried out.
[0040]
As shown in step 1-1 of FIG. 4, when an eject button provided on the nose portion 2 or the like is pressed and an eject request is issued to the control means 40, the first moving member 21 and the second moving member 22 is set to an interval corresponding to the diameter of the disc D to be ejected. In step 1-2, the carry motor Md is started, and the carry-in rollers 11, 12, 13, and 14 of the carry means 10 are driven counterclockwise, and carry-out output in the Y2 direction at the right edge of the disk. Is given. Therefore, the disk D is carried out in the Y2 direction so as to roll in the long groove 8A of the guide member 8.
[0041]
As shown in FIG. 1, when the disk D moves in the Y2 direction, the first carry-in roller 11 is pushed outward by the outer peripheral edge on the right side of the disk D, and the rotating arm 27 is rotated counterclockwise.
[0042]
While the disk D is being carried out, the control means 40 monitors the output of the first detection switch 23. When the center of the disk D coincides with the center of the first carry-in roller 11 and coincides with the discharge side end of the guide member 8, the detection piece 24b of the detection arm 24 is located on the left side of the disk D as shown in FIG. , The detection arm 24 is rotated in the clockwise direction, and the output of the first detection switch 23 is switched from the OFF state to the ON state (step 1-3). When the disc D is further ejected and the center of the disc D moves outward from the center of the first carry-in roller 11 and reaches the ejection position, as shown in FIG. 2, it follows the arc shape of the outer peripheral edge of the disc D. Thus, the detection arm 24 rotates counterclockwise and the first switch 23 further switches to the OFF state (step 1-4).
[0043]
At this time, the transport motor Md is stopped by the control unit 40 (step 1-5), and the ejection of the disk D is completed (step 1-6).
[0044]
When the ejection of the disk D is completed, the disk D is located in the entrance 2a and is further urged in the direction in which the open / close door 7 contacts the disk D as shown in FIG. In position, it is held in the entrance 2a. At this time, since the disk D is stopped at the discharge position where the center of the disk D has moved outward from the first carry-in roller 11, the projecting dimension of the disk D from the entrance / exit 2a to the outside increases, It becomes easier to grab the disk D and pull it out.
[0045]
When the disk D is held at the discharge position shown in FIG. 2, the first detection switch 23 is in the OFF state as described above, while the first carry-in roller 11 located on the right side. Since the center of the disk D extends in the Y2 direction, the disk D is returned in the X2 direction along the arc locus of the outer peripheral edge of the disk D. Therefore, the rotation arm 27 is rotated clockwise, and the second detection switch 29 is OFF.
[0046]
In the disc device control means 40, after the disc D ejection operation is completed, a sensor (not shown) monitors whether or not the disc has been pulled out from the entrance / exit 2a within a predetermined time, and the disc still remains without being pulled out. Sometimes a reload request (step 2-1 in FIG. 5) is issued. Alternatively, when the disc ejection operation is completed, regardless of whether or not the disc D is pulled out from the entrance 2a, a reload request in step 2-1 is automatically issued when a predetermined time has elapsed by the timer. Also good.
[0047]
When the reload request (re-import request) in Step 2-1 is issued, the states of the first detection switch 23 and the second detection switch 29 are monitored (Step 2-2). When both the second detection switches 23 and 29 are ON, the disk D is at the position shown in FIG. 1 at this point, that is, the disk D is pushed in a little, for example, so that the center of the disk D is the first carry-in. It is determined that the portion having the diameter dimension of the disk D located at the position coincident with the center of the roller 11 is sandwiched between the guide member 8 and the first carry-in roller 11.
[0048]
At this time, without changing the positions of the first moving member 21 and the second moving member 22, the process proceeds to step 2-10, the carry-in motor Md is started, and the first to fourth carry-in rollers of the carrying means 10 are started. 11, 12, 13, and 14 are operated clockwise, and the disk D is loaded to a position held by the disk holder. .
[0049]
In Step 2-2, when at least one of the first and second detection switches 23 and 29 is in an OFF state, the process of the control means 40 proceeds to (Step 2-3). In step 2-3, the conveyance motor Md is started to operate the first to fourth carry-in rollers 11, 12, 13, and 14 in the clockwise direction (load-in direction), and the setting motor Mr is further started. The first moving member 21 and the second moving member 22 are moved, and the distance between the guide member 8 and the conveying means 10 is gradually narrowed.
[0050]
At this time, when the disk D is held at the discharge position in the entrance 2a as shown in FIG. 2, the first carry-in roller 11 is an urging force that is an elastic pressure unit on the Y1 side from the center of the disk D. The outer peripheral edge of the disk D is gradually pressurized by the urging force of the member 26. Therefore, the transfer force from the carry-in roller 11 surely acts on the outer peripheral edge of the disk D, and the disk D is drawn in the Y1 direction.
[0051]
In this manner, the distance between the guide member 8 and the conveying means 10 is gradually narrowed and the carry-in roller 11 is pressed against the outer peripheral edge of the disk D, so that the center of the disk D is located closer to the Y2 side than the center of the carry-in roller 11. Even in this case, the disk D can be reliably loaded in the Y1 direction.
[0052]
Further, in the state of FIG. 2, the opening angle θ formed by the discharge end of the guide member 8 and the holding point where the disc is clamped by the carry-in roller 11 and the disc center is small, and this angle θ is small. If it is too high, even if the carry-in roller 11 is pressed against the outer peripheral edge of the disk D, it is possible that the component force in the carry-in direction from the carry-in roller 11 to the disk D cannot be reliably applied.
[0053]
However, in this embodiment, the left end portion of the entrance / exit 2a exists as a support portion 2b further outward (Y2 direction) than the discharge side end portion of the guide member 8. Therefore, in the state of FIG. 2, when the gap between the guide member 8 and the conveying means 10 is narrowed and the carry-in roller 11 is pressed against the outer peripheral edge of the disc D, the disc D is sandwiched between the support portion 2 b and the carry-in roller 11. Thus, the opening angle of the clamping point from the center of the disk at this time is θ1, which is wider than θ. Therefore, the component force increases in the Y1 direction of the carry-in input acting on the outer peripheral edge of the disk D from the carry-in roller 11, and the disk D is easily pulled in the Y1 direction.
[0054]
When the disk D is loaded in the Y1 direction, the rotating arm 27 supporting the loading roller 11 is rotated counterclockwise, and the detection arm 24 is rotated clockwise. Both 23 and 29 are turned on (step 2-4). At this time, the control means 40 moves to the processing of step 2-5, controls the setting motor Mr, moves the first moving member 21 and the second moving member 22, and opposes the guide member 8 and the conveying means 10. Increase the interval gradually. The carry-in rollers 11, 12, 13, and 14 of the transport means 10 continue to operate in the clockwise direction.
[0055]
Therefore, the disk D is carried in the Y1 direction by the guide member 8 and the conveying means 10. At this time, the output of the linear position sensor is monitored, and when the first moving member 21 and the second moving member 22 reach a position for conveying a small-diameter disk having a diameter of 8 cm, the outputs of both detection switches 23 and 29 are output. Monitor. At this time, if both the detection switches are not ON but only one of them is ON, it is determined that the reloaded disk is a small-diameter disk, and the first moving member 21 and the second moving member 22 are moved. Stop at that position. On the other hand, when both the detection switches 23 and 29 are ON, it is determined that the large-diameter disk having a diameter of 12 cm is being reloaded, and the first moving member 21 and the second moving member 22 are moved to the large diameter. Move to the position where the disk is transported and stop at that position.
[0056]
As described above, the disk D is reloaded and loaded into the disk drive unit 6. Alternatively, it is loaded in a position held by the disc holder (step 2-6).
[0057]
Then, by narrowing the gap between the guide member 8 and the transfer mechanism 10 in the step 23, and the results obtained by monitoring the outputs of both the detection switches 23 and 29 in step 2 4, both the detection switches 23 and 29 are both If it is not ON, in step 2-7, the output of the linear position sensor is checked to confirm whether or not the facing distance between the guide member 8 and the conveying means 10 has reached a position smaller than the diameter of the small-diameter disk. When the interval is not narrower than the diameter of the small-diameter disk, the process returns to step 2-3, and the setting motor Mr is started again, and the operation of narrowing the interval between the guide member 8 and the conveying means 10 is performed.
[0058]
In step 2-7, when the interval is already confirmed as Ru der following small-diameter disk diameter disk D is not held in the doorway 2a, determines that withdrawn from the doorway 2a (step 2-8) The reloading process is stopped (step 2-9).
[0059]
In the above-described embodiment, the distance between the guide member 8 and the conveying means 10 is narrowed during the reloading process shown in FIG. However, when the disk is inserted for the first time or when the disk D at the discharge position in FIG. 2 is pushed by hand, the disk D is inserted into the Y1 while gradually decreasing the facing distance between the guide member 8 and the conveying means 10. It may be carried in the direction and then operated so as to gradually widen the facing interval.
[0060]
Further, when changing the distance between the guide member 8 and the transport unit 10, only one of the guide member 8 and the transport unit 10 may be moved.
[0061]
【The invention's effect】
According to the present invention described in detail above, when the disk is inserted or re-loaded, the disk can be securely held between the guide member and the conveying means and fed into the apparatus. Further, even when the projecting dimension from the disk entrance / exit is large, the re-in operation can be performed reliably.
