Description

  The present invention relates to a disk device adopting a loading system, and more particularly to a disk device that can project a disk greatly from an entrance.

  In a conventional in-vehicle disk device, as described in Patent Document 1 below, the edge of the disk is sandwiched between a guide member and a conveying means, and a conveying force is applied from the conveying means to the disk. Some are carried into the apparatus and are carried out from the apparatus.

  In this type of disk device, when a disk is inserted from the doorway and when a command to eject the disk is issued, a conveying force is applied to one edge of the disk from the conveying means, and the other edge of the disk is The part is transferred while rolling along the guide member.

Since this disk apparatus does not use a conventional conveying roller for clamping the disk from above and below in the thickness direction, the mechanism can be made thin.
JP 2002-329360 A

  However, in the structure in which the disk is held between the guiding means and the conveying means and the disk is carried out, the carry output from the conveying means to the disk can be applied because the center of the disk is carried out by both the guiding means and the conveying means. Up to a position that substantially coincides with the side end, that is, until the portion where the width dimension of the disk is the largest reaches the unloading side end of the guiding means and the conveying means, and the disk is further moved outside the apparatus by the conveying force of the conveying means. Cannot be transferred to.

  As described above, when the output of the disc is cut off at a position where the center of the disc coincides with the end on the carry-out side, the disc stops at a position where the center hole does not sufficiently protrude from the entrance opening that opens in the apparatus. Resulting in. When removing a disk from the disk device, it is common to put out a finger in the center hole of the disk and pull it out. However, as described above, if the center hole does not sufficiently protrude from the doorway, the disk can be removed from the doorway. The operation of taking out is difficult.

  In particular, when the nose portion is loaded with various electronic components and has a large depth dimension, the projecting dimension of the center hole of the disk from the doorway is further reduced.

  DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned conventional problems, and when a disk is sandwiched and carried by a guide means and a conveyance means, the disk can be sufficiently projected from the entrance and the conveyance operation can be stopped The object is to provide a device.

The present invention provides an inlet / outlet through which a disc is inserted, guide means located inside the entrance / exit to guide one edge of the disc, and opposed to the guide means, thereby applying a transfer force to the other edge of the disc. Conveying means, interval setting means for changing the facing interval between the guiding means and the conveying means, and control means for changing the facing interval by controlling the interval setting means,
When unloading the disc, set the facing distance between the guide means and the transport means to a transport interval that can transport the disk, operate the transport means in the unloading direction, and guide the disk after reaching the position where it protrudes from the entrance / exit A control is performed to stop the operation of the conveyance means before or after the discharge interval is set by narrowing the facing interval between the means and the conveyance means and setting the discharge interval so that the disk is further protruded from the entrance / exit It is a feature.

  In the disk apparatus of the present invention, when the operation of the conveying means is stopped, the facing distance between the guiding means and the conveying means is narrower than the distance when the disk is conveyed. The disc stops when it is slightly pushed out of the doorway. Therefore, the projecting dimension of the disc from the entrance / exit can be increased, and the disc can be easily taken out from the insertion port thereafter.

  For example, in the present invention, while the operation of the transport unit in the carry-out direction is continued, the interval between the guide unit and the transport unit is set to the discharge interval, and then the transport unit is stopped.

  In this structure, the disc is reliably projected from the insertion port in a state where the guide means and the transport means are set at the carry-out interval.

  However, in the present invention, when the disk reaches a position where it protrudes from the entrance / exit, the operation of the transport unit may be stopped, and thereafter, the interval between the guide unit and the transport unit may be narrowed to set the discharge interval.

  In the present invention, preferably, after the operation of the conveying means is stopped, control for expanding the guiding means and the conveying means is performed. In this case, it is preferable to widen the guide means and the transport means and set the transport interval.

  If the setting is made as described above, the disc can be immediately carried into the apparatus when the disc is pushed in after the operation of the conveying means is stopped.

  In the present invention, it is preferable that at least one of the guide means and the transport means is provided with an elastic pressure means for elastically holding the disk at the end on the disk carry-out side.

  If the elastic pressure unit is provided as described above, the disc can be securely held between the guide unit and the transport unit when the disc is pushed in after the transport unit has stopped.

  For example, the present invention is provided with detection means for detecting that the disk has reached a position protruding from the entrance, and after the detection means detects, the facing interval between the guide means and the transport means is reduced. The discharge interval is set, and the operation of the conveying means is stopped after a predetermined time after detection.

  In addition, when the re-insertion of the disc is detected after the operation of the conveying means is stopped, the conveying means can be started in the disk loading direction, or after the operation of the conveying means is stopped, When the disc is not pulled out from the entrance / exit even after a lapse of time, it is possible to control the carry-in of the disc by further narrowing the distance between the guide means and the transport means and operating the transport means in the carry-in direction. .

  In the above, when the disc is not pulled out from the entrance / exit after a predetermined time has passed, it is preferable that the interval between the guide unit and the transport unit is further narrowed than the discharge interval.

  By narrowing the distance between the guide means and the transport means to be smaller than the discharge distance, the disk can be securely held and loaded.

  The guide means does not have a disk transport function, or has a disk transport function in the same manner as the transport means.

  In the present invention, after the disk protrudes from the entrance / exit by the carry-out output of the transport means, the amount of protrusion of the disk from the entrance / exit is increased by controlling the distance between the guide means and the exit means. For example, the center hole of the disk can be reliably projected outside the doorway, and the disk can be easily taken out.

  The disk device 1 shown in FIG. 1 is provided with a nose portion 2 having a liquid crystal display panel and various operation members on the front of the device main body. The nose portion 2 is provided with a slit-shaped entrance / exit 2a extending in the width direction (X1-X2 direction). An opening / closing door 7 is provided at the entrance / exit 2a (see FIG. 3), and is supported so as to be pivoted inward of the apparatus about the shaft 7a so as to be opened.

  The rotating shaft 7a of the opening / closing door 7 is provided with a biasing means such as a torsion coil spring (not shown), and the opening / closing door 7 is biased in the closing direction. The disk D is inserted from the doorway 2a so as to push open the opening / closing door 7 inward (Y1 direction). Further, when the disk D is unloaded, the door opening mechanism (not shown) is operated to open the door 7 inward, and when the disk D starts to be unloaded from the doorway 2a, the door 7 is urged. It is biased in the closing direction by the means.

  As shown in FIGS. 1 and 2, a first moving member 21 and a second moving member 22 that move in the width direction are provided inside the entrance 2a. The first moving member 21 and the second moving member 22 are provided with rack portions facing each other. A connecting gear 41 that functions as a distance setting unit meshes with both the rack of the first moving member 21 and the rack of the second moving unit 22. When the connecting gear 41 is rotated by the setting motor Mr, the first moving member 21 and the second moving member 22 move in the approaching direction and the separating direction in synchronization.

  The first moving member 21 is provided with a guide member (guide means) 8 extending in the Y1-Y2 direction, which is the disk introduction / unload direction.

  A guide long groove 8A extending in the Y direction in the drawing is formed on the surface of the guide member 8 on the opposite side (X1 side in the drawing). 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.

  A detection arm (detection member) 24 is provided at the end of the guide member 8 on the carry-out 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).

  The detection arm 24 is formed with a detection piece 24b located at the end of the guide member 8 on the carry-out 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.

  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. When the detection arm 24 rotates counterclockwise and the detection piece 24b covers the carry-out side (Y2 side) end of the long groove 8A of the guide member 8, the pressing piece 24c is moved to the actuator. The first detection switch 23 is switched to the OFF state away from 23a.

  On the surface of the second moving member 22, a conveying means 10 composed of first to fourth conveying 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. Above and below the first to fourth transport rollers 11, 12, 13, 14 are formed flanges whose thickness gradually decreases from the center toward the outer periphery, and the outer periphery of each transport roller has a cross section V. A letter-shaped circumferential groove is formed. The edge of the disk D is held by the circumferential groove between the flanges.

  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 the conveying rollers 11, 12, 13, and 14, and the first to fourth conveying rollers 11, 12, 13, and 14 are all driven to rotate in the same direction. When the first to fourth transport 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).

  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 transport 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.

  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 conveying 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.

  A linear position sensor that detects the movement position of the first moving member 21 in the X direction is provided in the housing of the disk device 1. This 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, can detect the facing distance between the guide member 8 and the conveying means 10.

  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.

  A disk storage unit is provided at the back of the disk device 1 on the Y1 side. The disc storage portion is provided with 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 the disk holders are arranged in the thickness direction of the disk, and the disk holder can be moved up and down in the thickness direction of the disk. Furthermore, holder selection means for moving any one of the disk holders to a selection position that coincides with the conveyance path of the guide member 8 and the conveyance means 10 is provided. When any one of the disc holders is at the selected position, the disc is carried into the disc holder, and the disc held by the disc holder at the selected position is directed toward the entrance / exit 2a by the guide member 8 and the conveying means 10. Are carried out.

  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. The central hole of the disc inserted from the entrance 2a and sandwiched between the guide member 8 and the transport means 10 is held by the disc rotation driving means 4 and is driven to rotate. In addition, the disk held by the disk holder that has been moved to the selected position in the disk storage unit is sandwiched between the guide member 8 and the conveying means 10, pulled out by the power of the conveying means 10, and held by the disk rotation driving means 4. And is driven to rotate.

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.

  In a standby state where the insertion of the disk D is awaited, the guide member 8 and the conveying means 10 are opposed to each other at an interval slightly narrower than the diameter (8 cm) of the small-diameter disk.

  When the small-diameter disk is inserted from the entrance / exit 2a, at least one of the detection arm 24 and the rotation arm 27 is pushed outward. At this time, the first and second detection switches when the small-diameter disk is pushed in due to the relationship between the rotation stroke of the detection arm 24 and the rotation stroke of the rotation arm 27 and the diameter (8 cm) of the small-diameter disk. Only one of 23 and 29 is set to ON, and both the first and second detection switches 23 and 29 are set not to be turned ON at the same time.

  When only one of the first and second detection switches 23 and 29 is turned on, the control means 40 determines that a small-diameter disk has been inserted, and the first moving member 21 and the second moving member 22 are left and right. The guide member 8 and the transport means 10 are set to a small-diameter disk transport interval that can sandwich and transport the small-diameter disk. At the same time, the transport motor Md is started, and the small-diameter disk is carried in the Y1 direction toward the inside of the housing by the rotational force of each roller of the transport means 10. However, the small-diameter disk is not carried to the position where it is held by the disk holder, and the transport motor Md is stopped by rotation in which the center hole of the disk coincides with the center of the disk rotation driving means 4, and the center hole of the disk rotates. Clamped on means 4.

  When a large-diameter disk having a diameter of 12 cm is inserted in the standby state in which the guide member 8 and the conveying means 10 face each other at a slightly narrower distance than the diameter (8 cm) of the small-diameter disk, The rotating arm 27 is 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 sandwich the large-diameter disk. Is set to the large-diameter disk conveyance interval. At the same time, the transport motor Md is started, and the large-diameter disk is carried to the position held by the disk holder at the selected position in the disk storage portion by the rotational force of each roller of the transport means 10. Alternatively, the conveyance motor Md stops when the center of the large-diameter disk carried in by the rotational force of each roller coincides with the center of the disk rotation driving means 4, and the center hole of the large-diameter disk becomes in the disk rotation driving means 4. Clamped.

  Next, the disk unloading operation will be described. In the following, the case where the large-diameter disk is carried out will be mainly described, but the operation is the same when the small-diameter disk is carried out.

In the flowchart of FIG. 4, each step is indicated by “ST”.
In ST1 (step 1), an eject button provided on the nose portion 2 or the remote controller is pressed, and an eject request is issued to the control means 40. Until then, the first moving member 21 and the second moving member 22 have moved away from each other, and the guide member 8 and the conveying means 10 are located away from the disk held by the disk holder. Alternatively, the guide member 8 and the conveying means 10 are located away from the disk clamped by the disk rotation driving unit 4.

  When the ejection request is issued, in ST2, the setting motor Mr is started, the first moving member 21 and the second moving member 22 move in a direction approaching each other, and the guide member 8 and the conveying means 10 are opposed to each other. The interval is narrowed. In ST3, the output of the linear position sensor is monitored, and the moving distance between the first moving member 21 and the second moving member 22 is monitored. Then, it is determined whether or not the interval between the guide member 8 and the conveying means 10 is set to an interval (a large-diameter disc conveyance interval or a small-diameter disc conveyance interval) that matches the diameter of the disc D to be carried out.

  If it is determined in ST3 that the facing distance between the guide member 8 and the conveying means 10 is set to the large diameter disk conveying interval or the small diameter disk conveying interval, the process proceeds to ST4, the conveying motor Md is started, and each conveying roller is started. 11, 12, 13, and 14 are driven in the disk unloading direction. A transport output in the Y2 direction is given to the right edge of the disk D from each transport roller, and the disk D is transported in the Y2 direction so as to roll in the long groove 8A of the guide member 8.

  As shown in ST5, while the disk D is being carried out, the control means 40 monitors the output of the first detection switch 23 and / or the second detection switch 29. When the unloaded disk D moves to the vicinity of the unloading end of the guide member 8 and the conveying means 10, the first conveying roller 11 is pushed outward by the outer peripheral edge on the right side of the disk D, and the rotating arm 27 is moved. It is turned counterclockwise. Then, the second detection switch 29 is switched from OFF to ON by the rotating arm 27.

  Since the rotating arm 27 is urged clockwise by the urging member 26, the left edge of the disk D is pressed against the long groove 8 </ b> A of the guide member 8 by the first transport roller 11. As a result, when the center of the disk D substantially coincides with the center of the first transport roller 11 and the end of the guide member 8 on the carry-out side, the detection piece 24b of the detection arm 24 provided on the guide member 8 side is moved to the disk. The detection arm 24 is pushed clockwise by the left outer peripheral edge of D, and the output of the first detection switch 23 is switched from OFF to ON.

  When the disk is unloaded, the first detection switch 23 is switched from OFF to ON shortly after the second detection switch 29 is switched ON. Alternatively, the first detection switch 23 is switched from OFF to ON almost simultaneously with the second detection switch 29 being switched ON. Further, when the disk D is unloaded and the center of the disk D moves slightly outward from the center of the first transport roller 11, the detection arm 24 moves counterclockwise along the arc shape of the outer peripheral edge of the disk D. By rotating, the first switch 23 further switches from ON to OFF. Alternatively, the rotation arm 27 is rotated clockwise and the second detection switch 29 is switched from ON to OFF.

  When the control means 40 detects the operation of the first detection switch 23 or the second detection switch 29, the process proceeds to ST6 and the disk final ejection operation is performed.

  Here, the timing of the detection operation of the first detection switch 23 or the second detection switch 29 and the setting of the disc final ejection operation is performed by any of the following variations.

(1) Immediately after the second detection switch 29 is switched from OFF to ON, the operation proceeds to the disc final ejection operation.

(2) Immediately after the first detection switch 23 is switched from OFF to ON, the operation proceeds to the disc final ejection operation.

(3) After the above (1), immediately after the second detection switch 29 is further switched from ON to OFF, the operation proceeds to the disc final ejection operation.

(4) After the above (2), immediately after the first detection switch 23 is further switched from ON to OFF, the disk final ejection operation is performed.

  Any of the above (1) to (4) may be used. Alternatively, the series of detection operations (1) to (4) may be confirmed, and the disc final ejection operation may be performed at any timing of (2) to (4).

  Alternatively, the positions of both switches 23 and 29 may be determined so that only the first detection switch 23 operates and the second detection switch 29 does not operate when the disc is ejected. In this case, (2) or (4) is set.

  In the disc final ejection operation of ST6, the setting motor Mr is started while continuing the rotation of the transport rollers 11, 12, 13, 14 (at least the transport roller 11) in the unloading direction. As shown in FIG. 2, the first moving member 21 and the second moving member 22 are moved closer to each other, the facing distance between the guide member 8 and the conveying means 10 is narrowed, and the facing distance is set to the large-diameter disk conveying distance. Alternatively, the discharge interval is set to be narrower than the small-diameter disk conveyance interval. The narrowing distance from the large-diameter disk conveyance interval or the small-diameter disk conveyance interval to the discharge interval is about 1 to 10 mm. For example, when discharging a large-diameter disk, if the narrowing interval is set to 5 mm, the disk D can be pushed out in the Y2 direction by about 12 mm.

  In ST7, the time after the disc final ejection operation is started is measured by a timer, and if it is determined that a predetermined time has elapsed, the process proceeds to ST8. The predetermined time is about 100 to 1000 msec.

  In ST8, the conveyance motor Md is stopped, the rotation of the conveyance rollers 11, 12, 13, 14 is stopped, the setting motor Mr is started, and the first moving member 21 and the second moving member 22 are separated from each other. And the facing distance between the guide member 8 and the conveying means 10 is increased. When the large-diameter disk is unloaded, the gap between the guide member 8 and the conveying means 10 is set to the large-diameter disk conveyance interval, and when the small-diameter disk is unloaded, the small-diameter disk conveyance interval is set. Then, the discharging operation is completed (ST9).

  As described above, after the center of the disk reaches the end of the guide member 8 and the conveying means 10 on the carry-out side, the disk D is discharged from the entrance / exit 2a (Y2 direction) by performing the final disk discharge operation of ST6. As shown in FIG. 2, the center hole of the disk D can be completely projected outward from the outer surface of the nose portion 2. Therefore, it becomes possible to insert the finger into the center hole of the disk D and take out the disk D from the entrance 2a.

  In ST8, when the distance between the guide member 8 and the conveying means 10 is increased and the large-diameter disk conveying interval or the small-diameter disk conveying interval is set, the edge of the disk D becomes the long groove 8A or the outer peripheral groove of the conveying roller 11. It is possible that they will fall out of the range. However, as shown in FIG. 3, when the ejection of the disk D is completed, the disk D is positioned in the entrance / exit 2a, and the opening / closing door 7 is biased in the nose portion 2 in a direction in which the disk D comes into contact with the disk D. The disc D is held in the doorway 2a in a state of protruding from the nose portion 2.

  In the disc device control means 40, after the disc D is unloaded, the 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 is issued.

  When a reload request (reloading request) is issued, the transport motor Md is started to start the transport rollers 11, 12, 13, and 14 in the transport direction. At the same time, the setting motor Mr is started to move the first moving member 21 and the second moving member 22 closer to each other, and the operation of narrowing the facing distance between the guide member 8 and the conveying means 10 is performed. The facing distance between the guide member 8 and the conveying means 10 when narrowed may be the discharge interval set in ST6, but is preferably narrower than the discharge interval.

  By this operation, the disk D supported by the entrance / exit 2a is sandwiched between the long groove 8A of the guide member 8 and the outer peripheral groove of the conveying roller 11. Since the rotating arm 27 receives the urging force from the urging member 29 and is pressed into contact with the outer peripheral edge of the disk D so that the V-shaped outer peripheral groove of the conveying roller 11 is engaged, the rotation of the conveying roller 11 in the loading direction is performed. The force acts on the outer peripheral edge of the disk D, and the disk D is carried in the Y1 direction. After the disk D starts to be carried in, the distance between the guide member 8 and the conveying means 10 is gradually widened by the setting motor Mr, and is set to the large diameter disk conveying interval or the small diameter disk conveying interval. Similarly, the disk D is carried into the housing. Then, the disk is held by the disk holder at the selected position, or the center hole of the disk D is clamped by the disk rotation driving means 4.

  Further, as shown in ST9, the disc ejection operation is completed, the facing distance between the guide member 8 and the conveying means 10 is set to the large diameter disc conveying interval or the small diameter disc conveying interval, and the disc D is supported by the entrance / exit. When the disk D is further pushed into the disk D case, the same operation as when the disk is inserted is performed. That is, in the case of a large-diameter disk, when both the first detection switch 23 and the second detection switch 29 are turned on at the same time, the transport rollers 11, 12, 13, and 14 are rotated in the loading direction so that the disk is It is brought in. In the case of a small-diameter disk, when one of the first detection switch 23 and the second detection switch 29 is turned on, the transport rollers 11, 12, 13, and 14 are rotated in the loading direction, and the disk is loaded. .

  Thus, in ST8, when the disk unloading is completed, the guide member 8 and the guide means 10 are set to the large-diameter disk conveyance interval or the small-diameter disk conveyance interval, so that the disk supported by the entrance / exit is reinserted. In this case, the disk can be loaded into the housing by the same control as in the normal disk insertion operation.

  In the present invention, in the final disc ejection operation of ST6, the gap between the guide member 8 and the conveying means 10 is reduced without rotating the conveying roller 11 in the carrying-out direction, and the guide member 8 and the conveying means 10 approach each other. The disc D may be pushed out in the Y2 direction by the force to be applied.

  Further, when the final disc ejection operation of ST6 is completed, the facing distance between the guide member 8 and the conveying means 10 may be kept narrow. In this case, when the insertion of the disk is detected, the transport rollers 11, 12, 13, and 14 are started in the carry-in direction, and control is performed to gradually widen the facing distance between the guide member 8 and the transport means 10.

  Alternatively, the guide member 8 may be provided with a plurality of transport rollers, and the disk may be transported by the rotational force of both the transport roller of the guide member 8 and the transport rollers 11, 12, 13, 14 of the transport means 10. Further, instead of the conveying roller, a belt extending in the Y1-Y2 direction may circulate, and the disk may be transferred by the circulatory force of the belt.
