[0010]
[Problems to be solved by the invention]
However, the above-described magazine-loading type recording medium driving device has the following problems.
Since the magazine 2 is made of synthetic resin, the bottom surface 2B on which the guide groove 2a is formed is soft and easily bent. Furthermore, if the overall thickness of the disk device 1 is reduced and the number of disks D that can be stacked in the magazine 2 is increased, it is necessary to reduce the thickness of the bottom surface 2B of the magazine 2. As a result, the rigidity of the bottom surface 2B further decreases. In addition, when the thickness of the bottom surface 2B is reduced, the depth t of the guide groove 2a shown in FIG.
[0011]
As a result, when the magazine 2 is loaded, the lock pin 4b is disengaged from the guide groove 2a on the bottom surface 2B of the magazine 2, and the bottom surface 2B is bent and deformed, so that the portion other than the guide groove 2a on the bottom surface 2B It may ride on the lock pin 4b. When such a phenomenon occurs, the magazine 2 cannot be reliably loaded into the disk device 1 in a normal posture.
[0012]
Even if the magazine 2 is inserted into the disk device 1 in a normal posture and the lock pin 4b is fitted and locked in the lock recess 2c, the lock pin is urged in the α1 direction by the urging member 6. There is a possibility that 4b may come off from the lock recess 2c due to, for example, vibration of a car. If the lock pin 4b is removed from the lock recess 2c, the magazine is not held in a normal posture in the disk device 1. For example, when the disk is returned from the disk drive unit to the magazine 2, the disk is not stored in the magazine 2. Problems such as failure to return to the normal position occur.
[0013]
The present invention is for solving the above-described conventional problems, and even if the bottom surface of the magazine is easily bent, the magazine can be reliably guided and loaded, and further, the magazine can be reliably locked in the apparatus. It is an object of the present invention to provide a recording medium driving device of the type.

This tray is pulled out in the Y1 direction by a tray pulling device provided in the drive unit K shown in FIG. 1, and the tray is returned into the magazine M when the disk is loaded in the drive unit K. It has become.
[0035]
As shown in FIG. 3, substantially L-shaped guide grooves Ma and Mb are provided on the opening M1 side of the bottom plate M2 of the magazine. As shown in FIG. 2, the guide grooves Ma and Mb are formed through the bottom plate M <b> 2 of the magazine M inward and outward. The guide grooves Ma and Mb include insertion portions Ma1 and Mb1 extending in the insertion direction of the magazine M, and contact portions Ma2 and Mb2 extending in a direction perpendicular to the insertion direction of the magazine M on the back side. Lock recesses Ma3 and Mb3 extending in the X1 direction from the contact portions Ma2 and Mb2 are provided.
[0036]
As shown in FIGS. 3 and 5, in all the inner portions of the insertion portions Ma1 and Mb1, the contact portions Ma2 and Mb2, and the lock recesses Ma3 and Mb3 of the guide grooves Ma and Mb, a step is formed on the inner surface side of the bottom plate M2. The thin sandwiching portions Ma4 and Mb4 are formed to extend into the insertion portion and the lock recess.
[0037]
As shown in FIG. 2, the thickness dimension t1 of the thin sandwiching portions Ma4 and Mb4 is high between the lower surface of the heads 18a and 19a of the sliding members 18 and 19 and the guide surface (the surface of the top plate 11C). It is formed slightly thinner than the length h. The thickness t2 of the bottom plate M2 of the magazine M is substantially equal to the height from the guide surface to the top surfaces of the heads 18a and 18b, or the thickness t2 is equal to or greater than the height. .
[0038]
As shown in FIG. 3, the distance W1 between the centers of the guide groove Ma and the guide groove Mb is set to be the same as the distance W0 between the axial centers of the sliding member 18 and the sliding member 19 ( W0 = W1). Therefore, when the magazine M is inserted in the Y1 direction shown in FIG. 3, the holding portions Ma4 and Mb4 of the guide grooves Ma and Mb of the magazine M are connected to the heads 18a and 19a of the sliding members 18 and 19 and the guide surface ( It is possible to enter between the surface of the bottom plate 11C. At this time, the upper surfaces of the sliding members 18 and 19 do not protrude significantly from the bottom plate M2 in the magazine M into the magazine.
[0039]
Further, the contact portion Mb2 of the guide groove Mb is located forward of the contact portion Mb2 of the guide groove Ma by a dimension L4 in the magazine insertion direction (Y1 direction). The length dimension L4 is set to be substantially the same as the length dimension L3 in the Y direction of the guide portion 14a of the control hole 14 (L3 = L4). In addition, a guide groove Mc that extends linearly in the Y direction shown in the figure, which is the insertion direction of the magazine, is formed on the lower surface of the bottom plate M2. The guide groove Mc is formed in a concave shape on the lower surface of the bottom plate M2, and does not penetrate the bottom plate M2.
[0040]
The operation of the magazine-loaded recording medium driving apparatus configured as described above will be described.
As shown in FIG. 3, in the standby state before the magazine M is loaded in the magazine loading unit 11A, the lock member 15 is in the standby position (A). That is, the guide / lock pin 16 provided on the lock member 15 is positioned at the sign (1) at the left end (X2 direction) of the long hole 13. The other guide / lock pin 17 is located at the sign (3) of the Y2 side end of the guide portion 14a of the control hole 14. The lock member 15 is rotated in the discharge direction (in the direction of β1 in the drawing) by using the guide / lock pin 16 at the position of the reference numeral (1) as a fulcrum by the Y2 direction component of the urging force F of the urging member 21. .
The state in which the lock member 15 is positioned at symbol (A) is the standby position before loading the magazine and the discharge position for discharging the magazine M from the magazine loading section 11A.
[0041]
When the magazine M is inserted into the magazine loading portion 11A of the housing 11 of the disk device from the Y1 direction in the figure, first, the magazine M is fixed on the bottom plate 11C of the magazine loading portion 11A in the guide groove Mc formed in the bottom plate M2 of the magazine M. The guide convex portion 12a enters. When the magazine M is further inserted, the guide convex portion 12b enters the guide groove Mc. Therefore, the guide groove Mc of the magazine M is guided by the pair of guide convex portions 12a and 12b and is linearly guided in the Y1 direction.
[0042]
As shown in FIG. 3, since the guide groove Mb of the magazine M is formed in the insertion direction (Y1 direction in the drawing) from the guide groove Ma, in the process of inserting the magazine M, the guide convex portion will be described in detail. Immediately before 12b enters the guide groove Mc, the sandwiching part Mb4 previously formed in the insertion part Mb1 of the guide groove Mb is between the head 19a of the sliding member 19 and the surface (guide surface) of the bottom plate 11C. Get in. Further, when the magazine M is inserted in the Y1 direction in the drawing, the sliding protrusion 19c of the sliding member 19 comes into contact with the contact portion Mb2 of the guide groove Mb. At this time, the clamping portion Ma4 formed in the insertion portion Ma1 of the guide groove Ma enters between the head portion 18a of the sliding member 18 and the guide surface.
[0043]
Thus, in the process of inserting the magazine M, the holding portions Ma4 and Mb4 formed on the bottom plate M2 of the magazine M are held between the heads 18a and 19a of the sliding members 18 and 19 and the guide surface. Therefore, while the magazine M is inserted, the sliding protrusions 18c and 19c of the sliding members 18 and 19 do not come off from the guide grooves Ma and Mb.
[0044]
When the magazine M is further inserted in the Y1 direction, the sliding protrusion 19c of the sliding member 19 is pressed in the insertion direction (Y1 direction) by the contact portion Mb2 of the guide groove Mb. Therefore, the lock member 15 is rotated in the β2 direction with the guide / lock pin 16 on the left side in the drawing as a fulcrum, and the sliding member 19 reaches the position indicated by the broken line (4) indicated by the broken line. At this time, since the lock member 15 receives the force of the X1 direction component of the urging force F of the urging member 21, the lock member 15 is moved in the X1 direction in the figure, and the guide / lock pin 17 is moved to the control hole 14. It enters into the lock part 14b. As a result, the lock member 15 reaches the lock position (B) shown in FIG.
[0045]
Therefore, the sliding member 18 on the left side of the figure reaches the position indicated by reference numeral (2) moved in the X1 direction in the long hole 13, and at the same time, the sliding member 19 indicates reference numeral (4) in the control hole 14 shown in FIG. From the position of ▼, it is moved to the position of reference numeral (5) shown in FIG. 4 moved in the X1 direction (see FIG. 4).
[0046]
At this time, the sliding members 18 and 19 move in the X1 direction in the respective guide grooves Ma and Mb of the magazine M. Therefore, the sliding members 18 and 19 enter the lock recesses Ma3 and Mb3. As a result, the magazine M is locked in the magazine loading section 11A so that it cannot be discharged in the Y2 direction.
[0047]
Since a component force in the X1 direction of the urging force F by the urging member 21 is acting on the lock member 15 in the lock position (b) shown in FIG. Lock recesses Ma3 and Mb3 of the guide grooves Ma and Mb are pressed in the X1 direction. The magazine M is pressed against the wall surface on the X1 side of the magazine loading portion 11A or the side surfaces of the pair of guide convex portions 12a and 12b by this pressing force, and the magazine M located in the magazine loading portion 11A is not rattling. Can be prevented.
[0048]
As shown in FIG. 5, in the locked state, the holding portions Ma4 and Mb4 of the lock recesses Ma3 and Mb3 formed in the guide grooves Ma and Mb of the magazine M are the guide surfaces and the heads 18a of the sliding members 18 and 19. 19a in this locked state, the sliding members 18 and 19 do not come out of the locking recesses Ma3 and Mb3, and the magazine M is held in the magazine loading portion 11A in a stable state. .
[0049]
In this way, while the sliding members 18 and 19 reach the lock recesses Ma3 and Mb3 from the insertion portions Ma1 and Mb1 of the guide grooves Ma and Mb of the magazine M, the clamping portions Ma4 and Mb4 are sandwiched under the heads 18a and 19a. Therefore, even if the bottom plate M2 of the magazine M is soft and thin and easily deformed, the bending or bending of the bottom plate M2 is corrected by being pressed against the guide surface by the heads 18a and 19a. Therefore, the bottom plate M2 is in close contact with the guide surface, and as a result, the other guide convex portions 12a and 12b are difficult to come out from the guide groove Mc on the bottom surface of the magazine M.
[0050]
On the other hand, as shown in FIG. 4, when the lock member 15 moves to the lock position (b), the actuator 22a of the detection switch 22 is pressed by the pressing piece 15b of the lock member 15, and the switch state of the detection switch 22 is switched. . Thereby, it can be detected that the magazine M is loaded in the magazine loading unit 11A.
[0051]
When a magazine discharge switch or the like provided on the front panel or remote controller of the disk device is operated, the magazine M is discharged from the magazine loading unit 11A. At this time, the lock member 15 is at the position indicated by the symbol (b) shown in FIG. 4, and the lock release portion 15c of the lock member 15 is pushed in the X2 direction by a lock release drive member (not shown). By this pressing force, the guide / lock pins 16 and 17 move in the X2 direction through the long hole 13 extending in the X direction and the lock portion 14b extending in the same direction. That is, since the long hole 13 and the lock portion 14b extend in parallel in the same direction, the entire lock member 15 linearly moves in the X2 direction by the pressing force in the X2 direction applied to the lock release portion 15c.
[0052]
As a result of the linear movement, when the guide / lock pin 17 exits the lock portion 14b and reaches the guide portion 14a, the left guide / lock pin 16 moved to the position (1) by the urging force of the urging member 21. As a fulcrum, the lock member 15 is rotated in the β1 direction. At this time, the sliding members 18 and 19 fixed to the guide / lock pins 16 and 17 come out of the lock recesses Ma3 and Mb3 of the magazine M, and the contact portion Mb2 of the guide groove Mb of the magazine M is moved by the sliding member 19. Pressed in the Y2 direction, the magazine M is discharged from the magazine loading unit 11A in the Y2 direction.
During this time, since the holding portions Ma4 and Mb4 of the magazine M are held under the heads 18a and 19a of the sliding members 18 and 19, the magazine M is surely discharged.
[0053]
In the above embodiment, the lock member 15 is provided with two guide / lock pins. However, the present invention is not limited to the above embodiment, and the lock member 15 receives one guide / lock pin. Alternatively, three or more may be provided.
[0054]
【The invention's effect】
According to the present invention described in detail above, even if the bottom plate of the magazine is soft and thin, the magazine is reliably guided by the protrusions. Further, when the magazine is locked by the protrusion, the protrusion does not come out of the lock recess of the bottom plate of the magazine, and the locked state is stabilized.
