Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a disk device that is applied to a player or a recorder that records or reproduces data on a disk such as an optical disk, or performs recording and reproduction.
[0002]
In particular, the present invention relates to an autoloading mechanism for a cartridge mounting member that loads (loads) an optical disk stored in a cartridge into an optical disk apparatus or ejects the optical disk to the outside.
[0003]
[Prior art]
The conventional optical disk recording / reproducing apparatus shown in FIGS. 15 to 18 will be described. In the figure, 201 is a main body of an optical disk recording / reproducing apparatus, 204 is a cartridge 1 in which an optical disk (not shown) is stored, and a tray on which a single optical disk (not shown) is placed, and 205 is a cartridge provided on the tray 204. 1 is a state detection switch for detecting the completion of placement, and 206 is a flexible lead for connecting the state detection switch 205 and the control circuit.
[0004]
At the center of the cartridge mounting surface 233 of the tray 204, two large and small concave portions provided concentrically are provided. The large-diameter concave portion is prepared by the large-diameter disk mounting portion 231, and the small-diameter concave portion is prepared by the small-diameter disk mounting portion 232 so as to be selectively used according to the outer diameter of the disc mounted on the disc recording / reproducing apparatus main body 201.
[0005]
The tray 204 is formed with 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 1 and are formed perpendicular to the cartridge mounting surface 233. A cartridge preload member 237 is provided on the back side of the tray 204 via a compression coil spring 237a so as to be movable in the front-rear direction. The cartridge preload member 237 is held by the holding unit 250 in a state of being preloaded on the front side of the tray 204. It has a structure.
[0006]
On the back surface of the tray 204, a rack gear (not shown) that engages with the driving gear of the final stage of the loading gear system driven by the loading motor provided on the front side of the mechanical chassis is provided, and the rotation direction of the loading motor is determined. By switching, the tray 204 can be loaded and ejected.
[0007]
The operation of the disk recording / reproducing apparatus configured as described above will be described by taking as an example a case where a disk stored in the cartridge 1 is reproduced. When the cartridge 1 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 1. The cartridge 1 is slid obliquely downward from the upper front side of the tray 204, and is finally placed on the cartridge placement surface 233 so that the front end of the cartridge 1 is in contact with the inner wall surface of the front wall surface 234. 1 is completed.
[0008]
At this time, the front end of the cartridge 1 is pressed to the inside of the front wall surface 234 by the cartridge preload member 237, and the cartridge 1 is substantially positioned with respect to the tray 204 without shaking back and forth.
[0009]
Further, the detection switch 205 is pushed on the side surface of the insertion end of the cartridge 1. For this reason, the loading motor 212 starts to operate, and the tray 204 on which the cartridge 1 is placed is automatically loaded into the disc recording / reproducing apparatus main body 201 by the driving force of the loading motor 212. The cartridge is finally positioned with respect to the tray 204 and the spindle motor by an insertion operation of an alignment pin (not shown) integrally formed on the traverse base to which the spindle motor, the optical pickup, etc. are fixed.
[0010]
[Problems to be solved by the invention]
The above conventional example has the following problems.
[0011]
(1) When inserting a cartridge into the optical disc recording / reproducing apparatus side, it is necessary to avoid the front wall surface at the front end of the tray and insert the cartridge into the optical disc recording / reproducing apparatus obliquely from above.
[0012]
When performing this operation, if the position in the height direction at which the optical disc recording / reproducing apparatus is installed is at least as high as the line of sight of the operator performing the insertion operation, the cartridge insertion operation becomes unnatural and is easy to use. It was bad.
[0013]
(2) When the cartridge is inserted into the recording / reproducing apparatus, after the cartridge is pushed against the pre-load to the front of the cartridge pre-load member, the front wall of the tray, the left wall, the right wall, and the cartridge pre-load member After confirming that the cartridge is completely mounted on the enclosed cartridge mounting surface, insert the cartridge into the optical disc recording / reproducing device by pushing the tray into the device or operating the loading switch installed in another part Needed multiple actions to complete.
[0014]
(3) In this case, if the operator makes an operation error, the cartridge is placed on the tray in an irregular state, and the tray is loaded with the cartridge mounted on the front wall surface or the left and right wall surfaces, The tray opening portion of the optical disc recording / reproducing apparatus and the cartridge interfere with each other, and the loading operation is interrupted.
[0015]
However, in the configuration in which the cartridge itself avoids an erroneous loading operation, there is a possibility that the surface of the cartridge may be damaged or the cartridge may be damaged in the worst case.
[0016]
(4) If a detection switch is provided on the tray that moves during loading and ejection, for example, the cartridge is automatically inserted into the optical disc recording / reproducing apparatus without pushing the tray or operating an operation switch set in another part. Can be completed.
[0017]
However, since the detection switch also moves together with the tray, the routing of the wiring member for transmitting a signal becomes complicated, resulting in lack of reliability.
[0018]
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an auto loading mechanism for a disk device that can simplify the loading operation of the cartridge, simplify the routing of the wiring member of the detection switch, and maintain the reliability.
[0019]
[Means for Solving the Problems]
The present invention comprises the following means in order to solve the above problems.
[0020]
  An auto loading mechanism for a disk device according to claim 1, wherein the device main body;SaidA cartridge mounting member that is provided so as to be able to be carried into and out of the apparatus main body and mounts a cartridge containing a disk; andSaidDriving means for carrying in or carrying out the cartridge mounting member to or from the apparatus main body;The cartridge mounting member is detachably engaged with the engaged portion of the cartridge to position and fix the cartridge relative to the cartridge mounting member, and based on the operation of the engaging portion. Cartridge holding means that also functions as a detection member for detecting that the cartridge is disposed at a normal position.Provided in the device bodyBeforeCartridgeA detection signal is output in response to the detection operation of the holding means.It comprises a mounting detection means and a control means for inputting the detection signal and outputting an operation command to the driving means.
[0021]
  For this reason, for example, an optical disc can be used without pushing the tray or operating an operation switch set in another part only by detecting the loading of the cartridge into the proper position of the cartridge mounting member by the mounting detection means provided in the apparatus main body. It is possible to automatically complete the insertion of the cartridge into the recording / reproducing apparatus. In addition, since the mounting detecting means is installed not on the moving cartridge mounting member but on the fixed side of the mechanical chassis, for example, wiring of the state detecting means can be facilitated and reliability can be ensured, and the cartridge can be mounted on the cartridge mounting member. The detection can be easily performed only by placing the cartridge, and the insertion of the cartridge can be automatically completed.
  Further, since the cartridge holding means serves both as the function of the engaging portion and the function of the detection member, it is not necessary to separately provide a detection means for detecting the completion of the cartridge at the normal cartridge placement position. Further, even if the state detection means and the cartridge at the normal placement position are separated by the intervention of the cartridge holding means, it is easy to install the attachment detection means on the fixed side of the mechanical chassis, for example, not on the cartridge placement member that moves. In addition, wiring of the detection switch can be facilitated.

When the cartridge 1 is not properly placed on the tray 20, the bent portion 30 b of the detection member 30 is in an imaginary line state, away from the switch 31, and when the cartridge 1 is placed, the switch 31 is switched at the other end 30 c. Will be operated. The output line 34 of the detection switch 31 is wired to a substrate control circuit provided on the rear surface of the chassis 60. When the detection signal is input from the detection switch 31, the control circuit outputs an operation command to the loading motor 61 which is a driving means. I have to.
[0042]
The operation of the main body 140 of the disk recording / reproducing apparatus configured as described above will be described by taking as an example a case where the optical disk stored in the cartridge 1 is reproduced.
[0043]
FIGS. 10 to 11 show the case where the cartridge 1 is placed on the tray 20. The cartridge 1 is pushed in the direction in which the cartridge 1 is pushed onto the disk recording / reproducing apparatus main body 140 from the front of the tray 20 onto the cartridge placement surface 21. Slide.
[0044]
Since the left and right end surfaces of the cartridge 1 are being pushed into the tray 20 using the left wall surface 25 and the right wall surface 26 as guides, the distal end shape of the engaging portion 27b serving as the protrusion of the cartridge holder 27 has an inclined surface. The cartridge 1 is easily opened to the width of the left side wall 25 and the right side wall 26 by the insertion force of the cartridge 1.
[0045]
FIG. 12 shows a state where the cartridge 1 is further inserted and the engaging portion 27 b of the cartridge holder 27 is engaged with the engaged portion 6 of the cartridge 1 by the urging force of the coil spring 49. At this time, the operator can recognize that the engagement is completed by a change in the insertion force and a sound generated when the cartridge holder 47 is engaged.
[0046]
A stopper 35 for restricting the insertion limit of the cartridge 1 is provided on the back side of the cartridge mounting surface 21, and the engagement position of the cartridge 1 and the cartridge holder 27 and the insertion limit by the stopper 35 substantially coincide with each other. It is like that. This completes the placement of the cartridge 1 on the tray 20. At this time, the cartridge 1 is restricted from moving in the front-rear direction by the cartridge holder 27 and in the left-right direction by the left wall surface 25 and the right wall surface 26.
[0047]
At the same time, the detection member 30 is pushed at the insertion end of the cartridge 1, and the detection member 30 pushes the operation part 31 a of the detection switch 31 to output a detection signal. A detection signal is output to the control circuit, and the loading motor 61 operates.
[0048]
In this embodiment, the control circuit can be switched so that the driving means is not operated by the operation of the detection switch 31, and the following loading operation can be performed.
[0049]
That is, in the case of manual loading operation, the insertion force to be inserted into the tray 20 is continuously applied to the cartridge 1, and the insertion force is transmitted to the tray 20 through the stopper 35, and the tray 20 manually loads the disc recording / reproducing apparatus main body 140. To start against.
[0050]
While the tray 20 is being manually loaded, a tray passing signal is detected by an eject end switch (not shown) of the tray, a driving voltage is applied to the loading motor 61, and the driving is driven by the rotation of the loading motor 61. The tray 20 starts an automatic loading operation by the rotation of the gear 66.
[0051]
Here, when comparing the insertion force of the cartridge 1 into the cartridge holder 47 with the manual loading force of the tray 20,
After the placement of the cartridge 1 on the tray 20 is completed by setting the spring constant and preload of the coil spring 49 that biases the cartridge holder 27 so that the relationship of cartridge insertion force <manual loading force is established. The tray 20 is manually loaded.
[0052]
If the force relationship is reversed, loading of the tray 20 is started before the insertion of the cartridge 1 into the cartridge holder 47 is completed, and a clamping error of the disk 10 stored in the cartridge 1 occurs.
[0053]
On the other hand, in the case of the automatic loading operation, when loading of the cartridge 1 onto the tray 20 is completed, a loading switch (not shown) of the disc recording / reproducing apparatus main body 140 is turned on to apply a driving voltage to the loading motor 61. The tray 20 starts an automatic loading operation by the rotation of the drive gear 66 that follows the rotation of the loading motor 61.
[0054]
According to the configuration of the first embodiment, after the cartridge 1 is placed on the tray 20, the cartridge 1 is slid on the cartridge placement surface 21 when loading the tray 20 and the cartridge 1 onto the optical disc recording / reproducing apparatus main body 140. Thus, the loading operation is completed by continuing the insertion force as it is. In other words, in the conventional disc recording / reproducing apparatus, the operation of placing the cartridge 1 and the loading operation of the tray 20 is completed by a plurality of operations, and is completed only by the insertion operation of the cartridge 1.
[0055]
In addition, since the conventional disk recording / reproducing apparatus has a box shape having a front wall surface for positioning the cartridge with respect to the tray, when placing a single optical disk on the tray, avoid the front wall surface and place the disk on the tray. There was a sense of incongruity in the operation of placing. However, with the tray 20 of this embodiment, it is generally possible to employ a tray having substantially the same shape as a tray on which only a single optical disk is placed. Therefore, an operation for placing a single disk on the tray is possible. There is no sense of incongruity in sex. In addition, the freedom of the tray design has been improved by eliminating the front wall surface. For example, a high-quality design aiming at a design effect can be adopted from a function-oriented design.
[0056]
Further, according to the configuration of the first embodiment, after the cartridge 1 is placed on the tray 20, the cartridge 1 is slid on the cartridge placement surface 21 when the tray 20 and the cartridge 1 are loaded onto the optical disc recording / reproducing apparatus. The loading operation is automatically started just by releasing the hand from the cartridge 1 in the inserted state, and the cartridge 1 is mounted in the optical disc apparatus. In other words, in the conventional optical disc recording / reproducing apparatus, three series of operations including pushing the cartridge 1 into the tray 20, placing it in the normal position, pushing the tray, and other switched operations are necessary for recording / reproducing. However, it is completed only by placing the cartridge on the tray.
[0057]
Furthermore, it is possible to easily configure the means for detecting the placement of the cartridge 1 on the tray 20 after the placement on the tray 20 and the loading drive means without making it complicated. These easy configurations lead to increased reliability.
[0058]
(Second Embodiment)
A second embodiment of the present invention will be described with reference to FIGS. That is, in the first embodiment, the detection member 30 that drives the detection switch 31 as a means for detecting the completion of placement of the cartridge 1 at the normal position is also used as the cartridge holder 27, and the detection member 30 is omitted. Yes. In the embodiment, the switch pressing portion 27e protrudes from the end opposite to the engaging portion 27b of the cartridge holder 27 in the direction opposite to the spring receiving projection 27c, and the detection switch fixed to the chassis 60 on the switch pressing portion 27e. 31 operation parts 31a are opposed.
[0059]
FIG. 13 shows a state before the detection switch 31 is attached.
[0060]
FIG. 14A shows the same state as FIG. 13 in which the tray 1 is ejected and the cartridge 1 is not mounted on the tray 20. At this time, the operating portion 31a of the detection switch 31 is pressed by the switch 49 with the switch 49 by the spring 49. FIG. 14B shows a state in the middle of mounting the cartridge 1 on the tray 20, and the engaging portion 27b is pushed by the tip on both sides of the cartridge 1, and as a result, the switch pressing portion 27e is separated from the detection switch 31. is there. FIG. 14C shows a state in which the engaging portion 27 b is immersed and engaged with the engaged portion 6 of the cartridge 1, and the operation pressing portion 31 a of the detection switch 31 is pressed again by the switch pressing portion 27 e of the cartridge holder 27. . For this reason, the detection switch 31 outputs to the control means a signal accompanying a series of operations of leaving or being pushed from the state in which the operation unit 31a is pressed, and the control means detects that the cartridge 1 is properly mounted, A drive signal is output to a loading motor 61 which is a driving means, whereby the tray 20 starts loading, and the switch pressing portion 27e is separated from the operation portion 31a of the detection switch 31.
[0061]
According to the configuration of the third embodiment, the detection of the normal position of the cartridge 1 on the tray 20 is also used by the member that holds the cartridge 1, so that it is not necessary to separately provide a detection switch driving means. Thus, the cost of the optical disc recording / reproducing apparatus can be reduced.
[0062]
【The invention's effect】
  According to the auto loading mechanism of the disk device according to claim 1, the tray is pushed in or the other part is detected only by detecting the loading of the cartridge mounting member to the normal position by the mounting detecting means provided in the device main body. For example, it is possible to automatically complete the insertion of the cartridge into the optical disc recording / reproducing apparatus without operating the operation switch set to (2). In addition, since the mounting detecting means is installed not on the moving cartridge mounting member but on the fixed side of the mechanical chassis, for example, wiring of the state detecting means can be facilitated and reliability can be ensured, and the cartridge can be mounted on the cartridge mounting member. The detection can be easily performed only by placing the cartridge, and the insertion of the cartridge can be automatically completed.
  Further, since the cartridge holding means serves both as the function of the engaging portion and the function of the detection member, it is not necessary to separately provide a detection means for detecting the completion of the cartridge at the normal cartridge placement position. Further, even if the state detection means and the cartridge at the normal placement position are separated by the intervention of the cartridge holding means, it is easy to install the attachment detection means on the fixed side of the mechanical chassis, for example, not on the cartridge placement member that moves. In addition, wiring of the detection switch can be facilitated.
