Description

  The present invention relates to a loading mechanism for a mounting member for mounting a cartridge in a disk device.

  In general, in a disk device, a cartridge containing a disk is placed on a tray, and the tray is carried into and out of the apparatus main body.

  With reference to the conventional disk device (optical disk recording / reproducing device) shown in FIGS.

  In FIG. 26, 201 is a main body of an optical disk recording / reproducing apparatus, 204 is a tray on which a cartridge and a single optical disk are placed, and 100 is a cartridge in which an optical disk is stored.

  At the center of the cartridge placement surface 233 of the tray 204, two large and small concave portions arranged concentrically are provided. The large-diameter concave portion is the large-diameter disk mounting portion 231, and the small-diameter concave portion is the small-diameter disk mounting portion 232.

  The tray 204 has a front wall surface 234, a left wall surface 235, and a right wall surface 236 that are slightly larger than the outer dimensions of the cartridge 100 and are formed perpendicular to the cartridge mounting surface 233.

  As shown in FIG. 27, a cartridge preloading member 237 is provided on the back side of the tray 204 so as to be movable in the front-rear direction, and is held in a preloaded state on the front side of the tray 204.

  As shown in FIG. 28, a rack gear 288 that engages with the final stage drive gear of the loading gear system is provided on the back surface of the tray 204.

  The tray 204 is configured to be capable of loading and ejecting by switching the rotation direction of a loading motor (not shown) provided on the front side of the mechanical chassis 209.

  A slide cam 251 that engages with the mechanical chassis 209 is provided on the front side of the traverse base so as to be movable in the left-right direction.

  A rack gear 252 is provided on the front side of the slide cam 251 and is driven right and left by an intermediate gear of a loading gear system.

  As the slide cam 251 moves to the left and right, the traverse base, the alignment pin, and the detection lever are driven in the vertical direction.

  The operation of the optical disc recording / reproducing apparatus 201 configured as described above will be described by taking as an example a case where the optical disc stored in the cartridge 100 is reproduced.

  When the cartridge 100 is placed on the tray 204 surrounded by the front wall surface 234, the left wall surface 235, and the right wall surface 236, the cartridge preload member 237 is pushed toward the back side with respect to the tray 204 at the rear end of the cartridge 100. The cartridge 100 is slid obliquely downward from the upper front side of the tray 204, and finally placed on the cartridge placement surface 233 so that the front end of the cartridge 100 is in contact with the inner wall of the front wall surface 234. 100 placement is completed.

  At this time, the front end of the cartridge 100 is pressed against the inside of the front wall surface 234 by the cartridge preloading member 237, and the cartridge 100 is positioned with respect to the tray 204 without back and forth, right and left play.

  The tray 204 on which the cartridge 100 is placed is automatically loaded into the optical disc recording / reproducing apparatus 201 by the driving force of the loading motor.

  The tray 204 and the mechanical chassis 209 are resin molded products, and the sliding surface of the mechanical chassis 209 during loading is formed smoothly. The sliding surface of the lower surface of the tray 204 has a rail shape with a convex cross section, and several guide members are provided in the vicinity of the sliding surface of the mechanical chassis 209 to prevent meandering during loading of the tray 204. It has a structure.

  Until the tray 204 is completely loaded, the spindle motor, traverse motor, and optical pickup held on the traverse base are retracted below the loading path of the tray 204 in order to avoid interference with the tray 204, cartridge 100, and disk. doing.

  Immediately before the tray 204 reaches the insertion completion position, the pin 254 of the slide cam 251 engaged with the guide 253 provided on the lower surface of the tray is driven by the guide 253 provided on the lower surface of the tray. When it passes through the cam portion 255, it moves to the right.

  While the slide cam 251 moves to the right, the rack portion 252 engages with the intermediate gear and is driven. At the same time, the drive gear is detached from the rack of the tray 204 and is driven by the pin 254 of the slide cam 251.

  When the pin 254 of the slide cam 251 enters the horizontal portion of the guide 253, the movement of the tray 204 is completed.

The ejecting operation of the tray 204 is almost the reverse process of the loading operation, and a description thereof will be omitted.

  However, the conventional disk apparatus (optical disk recording / reproducing apparatus) as described above has the following problems.

  For example, if the shape of the pickup becomes large, or if the shape of the traverse base becomes large as a result of mounting multiple pickups of different types, the slide that moves the lower surface of the tray 204 to the right and left perpendicular to the tray insertion direction If the cam 251 is disposed, the drive height becomes high.

  In addition, when a plurality of pickups are mounted, the traverse base occupies most of the lower surface of the tray 204, so that the place where the gear for driving the tray 204 is arranged is limited and the slide cam 251 cannot be arranged. There was a problem.

  Further, in the case of the tray 204 corresponding to the cartridge 100, the depth dimension of the cartridge 100 is larger than that of the disk alone, so that it is necessary to increase the discharge amount of the tray 204 from the housing as compared with the tray corresponding only to the disk. The total length of the tray 204 needs to be increased. Since the depth of the drive depends on the total length of the tray, there is a problem that the total length of the drive is also increased.

  The present invention has been made in view of such problems, and it is not necessary to increase the drive height even when the traverse base is large, and to increase the discharge amount of the tray without increasing the depth dimension of the drive. It is an object of the present invention to provide a loading mechanism for a disc device that can be used.

It is provided and moves from the front end of the carry-in path end area to the middle of the area by being engaged with the holder member, and from the middle of the carry-in path end area to the rear end of the area by the driving means. When the placing member is separated from the drive means after the middle of the area, the holder member is engaged and moved, and the holder member is moved to the disk loading position at the rear end of the carry-in path end area. It is a loading mechanism of a disk device provided with a cam member to be lowered.

  The invention according to claim 2 is the invention according to claim 1, wherein the moving speed of the mounting member by the driving means and the moving speed of the cam member by the driving means are set to be equal to each other, and the carry-in path This is a loading mechanism for a disk device in which the mounting member is separated from the driving means after the cam member is connected to the driving means in the middle of the end region.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the holder member is provided so as to be swingable, and engages with the apparatus main body until the mounting member reaches before the carry-in path end region. Thus, the swinging member that holds the holder member in a stopped state is provided, and the swinging member is swung by the mounting member when the mounting member moves from the front of the carry-in path end region to the front end of the region. This is a loading mechanism of the disk device that is moved to disengage from the device main body and is engaged with the mounting member over the entire area of the carry-in path end.

A rack gear 52 is provided at the lower portion of the slide cam 51, and the rack gear 52 is provided at the lower right front portion of the apparatus main body 40. It meshes with a pinion gear 82 driven by a loading motor 80 (see FIG. 24) provided.

  Further, the left slide cam 50 is connected so as to move in the same direction as the right slide cam 51 moves. The moving speed of the left and right slide cams 50 and 51 by the pinion gear 82 and the moving speed of the tray 20 by the drive gear 81 are set to be equal.

  The left and right slide cams 50, 51 are formed with groove-like operating cams 53 (see FIG. 10) that engage the protrusions 63 on both sides of the tray holder 60, and are shown on the left and right side walls of the clamp arm 62. A groove-like operation cam 54 is formed to engage the protrusion that is not to be engaged.

  Further, the left and right slide cams 50, 51 are formed with an insertion side engagement wall 55 and a discharge side engagement wall 56 at the top of the operation cam 53.

  Further, projections (not shown) provided on the left and right side walls of the clamp arm 62 are also engaged with groove-like operation cams 54 (see FIG. 10) formed on the left and right slide cams 50 and 51.

  As shown in FIG. 11, a lock arm 70 is attached to the upper surface of the tray holder 60 so as to be swingable about a support shaft 71 and urged clockwise by a spring (not shown) in plan view. It has been.

  As shown in FIG. 9, the lock arm 70 includes a downward pin 72 and an upward pin 73 at the tip of the rocking portion. The downward pin 72 is configured to be freely disengaged from the guide groove 28 of the tray 20, and the upward pin 73 is a cam groove 46 formed in the top cover 45 along the loading / unloading direction, and the cam groove 46. The engaging groove 47 (see FIG. 15) that is substantially orthogonal to the engagement groove 47 is configured to be disengageable.

  Further, a long groove 48 extending in parallel with the cam groove 46 is formed in the top cover 45, and a protrusion 68 formed on the upper surface of the tray holder 60 is engaged with the long groove 48.

  Further, the top cover 45 is provided with a spring (not shown) that applies a force acting downward on the tray holder 60 when the tray holder 60 is in the raised state.

  Next, the operation of the disk device 10 configured as described above will be described.

<First step (see FIG. 25 (1))>
If the cartridge 1 is placed and an insertion force is applied to the tray 20 in a state where the tray 20 is ejected and pulled out from the apparatus main body 40, the tray 20 starts a loading operation on the apparatus main body 40 manually.

  During this manual loading operation, an eject end switch (not shown) of the tray 20 detects the passage of the tray, and the power of the loading motor 80 is turned on by the signal. As a result, the drive gear 81 meshing with the rack gear 27 starts to rotate and starts moving the tray 20 in the loading (loading) direction.

  At this time, the tray 20 is packed with the tray holder 60 and is not subjected to an excessive load. Therefore, the tray 20 smoothly moves along the tray holder 60 during the loading operation. Moving.

  At this time, since the lock arm 70 is in the position shown in FIGS. 11 and 12, the upward pin 73 is engaged with the locking groove 47 of the top cover 45. Therefore, since the tray holder 60 is integrally locked to the top cover 45 by the lock arm 70, the tray holder 60 is held in a stopped state even if the tray 20 moves.

<Second step (see FIG. 25 (2))>
When the rear end of the tray 20 (front end in the carrying-in direction) reaches the position of the downward pin 72 of the lock arm 70, the downward pin 72 enters the guide groove 28 of the tray 20 and moves along the inclination of the guide groove 28. The lock arm 70 swings counterclockwise (A direction) when viewed around the support shaft 71 in plan view against the biasing force of the spring.

  As a result, the upward pin 73 of the lock arm 70 is in the position shown in FIGS. 13 to 15, and the tray holder 60 is locked to the top cover 45 by moving from the locking groove 47 of the top cover 45 to the cam groove 46. Is released.

  At the same time, the downward pin 72 of the lock arm 70 engages with the front end of the guide groove 28 of the tray 20, whereby the tray holder 60 is integrally locked to the tray 20 in the loading direction by the lock arm 70. .

<Third step (see FIG. 25 (3))>
When the movement of the tray 20 by the drive gear 81 continues, the tray holder 60 locked to the tray 20 in the movement direction moves integrally with the tray 20. At this time, the upward pin 73 of the lock arm 70 moves along the cam groove 46 of the top cover 45, and the upper surface protrusion 68 of the tray holder 60 moves along the long groove 48 of the top cover 45.

  With the movement of the tray holder 60, as shown in FIG. 17, first, the projection 63 abuts against the insertion side engaging wall 55 of the slide cams 50 and 51 to cause the slide cams 50 and 51 to be inserted in the insertion direction (B direction). To follow.

  At this time, as shown in FIG. 18, since the protrusion 63 of the tray holder 60 is placed on the guide portion 42 of the mechanical chassis 41, the tray holder 60 moves in the horizontal direction along the guide portion 42.

<4th process (refer FIG. 25 (4))>
When the slide cams 50 and 51 are driven for a while due to the movement of the tray 20 and the tray holder 60 by the drive gear 81, the rack gear 52 of the slide cam 51 meshes with the pinion gear 82, and the slide cams 50 and 51 change from driven to gear drive. Switch.

  Then, the movement of the tray 20 and the tray holder 60 by the drive gear 81 and the movement of the slide cams 50 and 51 by the pinion gear 82 are parallel for a while.

<5th process (refer FIG. 25 (5))>
When the parallel movement state by the drive gear 81 and the pinion gear 82 continues for a while, the rack gear 27 of the tray 20 passes through the drive gear 81 and is disconnected from the drive source. Therefore, the tray 20 and the tray holder 60 are stopped at that position.

  On the other hand, since the slide cams 50 and 51 continue to move by the pinion gear 82, as shown in FIG. 19, the discharge side engaging wall 56 abuts against the protrusion 63 of the tray holder 60 so that the tray holder 60 is inserted in the insertion direction (B Direction).

  At this time, as shown in FIG. 20, since the protrusion 63 of the tray holder 60 is placed on the guide portion 42 of the mechanical chassis 41, the protrusion 63 does not descend along the operating cam 53, and the slide cams 50 and 51 are engaged on the discharge side. The contact state with the wall 56 is maintained.

  Further, when the tray holder 60 is driven in the insertion direction, the downward pin 72 of the lock arm 70 is inclined away from the front end of the guide groove 28 of the tray 20 if the lock arm 70 can swing clockwise as viewed in a plan view. The tray 20 is left behind.

  However, since the upward pin 73 of the lock arm 70 moves in the insertion direction along the cam groove 46 of the top cover 45, the lock arm 70 cannot swing, so the downward pin 72 of the lock arm 70 is guided by the guide. The tray 20 is driven together with the tray holder 60 while being engaged with the front end of the guide groove 28 by the inclination of the groove 28.

<6th process (refer FIG. 25 (6))>
When the slide holders 50 and 51 are moved by the pinion gear 82, the tray holder 60 is driven for a while with the tray 20, and the protrusion 63 reaches the position of the groove 43 of the mechanical chassis 41. The tray holder 60 is pushed downward by the action of the spring provided on the top cover 45, and the projection 63 is guided downward by the operation cam 53 of the slide cams 50 and 51 as shown in FIG. As a result, the projection 63 descends along the groove 43 of the mechanical chassis 41 as shown in FIG.

  As a result, the tray holder 60 is lowered to the disc loading height with the tray 20, and the disc on the tray 20 is loaded into the spindle motor.

  Immediately after that, a detection switch (not shown) detects the leading ends of the slide cams 50 and 51 in the insertion direction, thereby detecting that it is a loading end and stopping the operation of the loading motor 80.

  Since the ejection operation is the opposite of the loading operation described above, detailed description is omitted.

  According to the cartridge loading mechanism of the disk apparatus according to the present invention as described above, since the cam members (slide cams 50 and 51) can be configured on the left and right sides of the traverse base, even if the traverse base is very large, the drive height is almost the same. The loading mechanism can be configured without increasing.

  Further, when the movement amount of the tray 20 and the movement amount of the tray holder 60 are added, the horizontal movement amount of the tray 20 with respect to the drive can be increased, so that the tray without increasing the dimension in the drive depth direction (dimension in the depth direction of the tray 20). It is possible to increase the amount of 20 emissions.

  Further, as long as the phases of the drive gear 81 and the pinion gear 82 are matched, the linear velocity of the rack gear 27 of the drive gear 81 and the tray 20 and the linear velocity of the rack gear 52 of the pinion gear 82 and the slide cam 51 are constant. Therefore, the gear change from the drive gear 81 to the pinion gear 82 can be performed smoothly.

  In addition, since the protrusion 63 of the tray holder 60 cannot push the cam member (slide cams 50 and 51) until the tray 20 is completely moved with respect to the tray holder 60, malfunction can be prevented.

  Further, the lock arm 70 allows the tray 20 to be fixed to the tray holder 60 and moved together.
