DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium stocker device.

[0002]

2. Description of the Related Art Although there are various types of structural forms as stocker devices for recording media, for example, a "mini-disc exchange mechanism and its cartridge transfer device" disclosed in Japanese Patent Application Laid-Open No. 7-176126 is known. In the above technique, as shown in FIGS. 1 and 2 of the publication, a plurality of insertion holes 32 are provided in a front panel 31 for inserting a cartridge 25 containing a mini-disc. A plurality of holders 35 are arranged in a multi-stage shape inside the front panel 31, and one of the plurality of cartridges 25 stored in each of the plurality of holders 35 is placed on the deck 60.
And a number of eject buttons 41 corresponding to the insertion holes 32 of the front panel 31 for taking out the cartridge 25 from the insertion holes 32.

[0003]

However, according to the above technique, when the cartridge 25 containing the mini-disc is inserted into and removed from the holder 35 through the insertion hole 32,
Although it is easy to insert and remove the cartridges 25 at each stage one by one, it is difficult to insert and remove a plurality of cartridges 25 at the same time. The reason is as follows. When a plurality of cartridges 25 placed on a plurality of holders 35 are simultaneously inserted and removed, each cartridge 25
Have the same amount of protrusion to the front panel 31, and since the upper and lower cartridges 25 are closely spaced and overlap and project in parallel, it is difficult to grasp each cartridge 25. Further, such a recording medium stocker device requires an erroneous insertion detection mechanism for determining whether or not the cartridge 25 has been reliably placed at a predetermined position. In order to simultaneously insert and remove the plurality of cartridges 25, it is not sufficient to detect the erroneous insertion individually into the plurality of cartridges 25 in the related art. It is necessary to develop an erroneous insertion prevention mechanism that can detect whether or not the insertion has been completed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a stocker for recording media having a mechanism for preventing erroneous insertion which can detect a plurality of recording media at once.

Luo increases toward the lower part a stocker apparatus so that configuration the recording medium, movably provided in a direction substantially orthogonal to the insertion direction of the cartridge on the front side of the plurality of Sutokkatorei, and a plurality When the cartridge is inserted in a normal posture after the cartridge is inserted, the shutter is retracted to a position where it does not hinder the insertion of the cartridge when the cartridge is inserted. While the back surface of the cartridge is shielded by the shutter, when the cartridge is inserted in an incorrectly inserted posture, the cartridge is brought into contact with the side surface on which the back surface of the cartridge protrudes from a normal case.

When the cartridge is inserted in a proper posture, the rear surface of the cartridge is shielded by the shutter. When the cartridge is inserted by mistake, the rear surface of the cartridge protrudes, and the shutter hits the side surface of the cartridge. . Therefore, whether or not a plurality of cartridges can be placed at a predetermined position can be determined collectively based on whether or not the shutter is closed.

According to a second aspect of the present invention, there is provided a drive plate having a cam for moving the plurality of stocker trays and moving the shutter. Since the drive plate having the cam for performing the movement of the plurality of stocker trays and the movement of the shutter is provided, the movement of the stocker tray and the movement of the shutter can be moved by one drive system.

According to a third aspect of the present invention, the shutter prevents double insertion of the cartridge when the rear surface of the cartridge is shielded by inserting the cartridge in a proper posture. The shutter also prevents double insertion of the cartridge when the cartridge is inserted in a proper posture and shields the rear surface of the cartridge, so that a more reliable recording medium stocker device can be embodied.

Here, when the drive gear 64 further rotates counterclockwise, the base frame 12 moves further forward due to the engagement of the drive gear 64 with the rack 12a of the base frame 12. Accordingly, the pins 12b of the base frame 12 move from the second tapered portion 53d of the cam groove 53 formed in the drive plate 52 to the third straight portion 53e. On the other hand, the rack 5 of the drive plate 52
Since 2a is disengaged from the drive gear 64, the drive plate 52 does not move and reaches the left end. Therefore, the shutter portion 5 of the shutter 51 connected to the drive plate 52
1e is retracted to a position where it does not hinder the insertion and removal of the MD cartridge M from the first to third stocker trays 16 to 18.

FIG. 11 is an explanatory view (fourth) of the operation of the drive mechanism. This figure shows that when the drive gear 64 of the drive mechanism 60 further rotates counterclockwise, the base frame 12

The front pins 31g, 31g fixed to 17, 18 also slide forward with different amounts of movement along the front oblong holes 25d, 25e of the right sub-frame 25, respectively. At this time, the front pins 31g, 31
g and the amount of movement of the rear pins 31h, 31h depends on the distance from the fulcrum 12i of the cam plate 15 to the pins 31h, 31h of each stage, and the amount of movement of the third stocker tray 18 below the second stocker tray 17 at the middle stage. Is larger. Accordingly, the protrusions of the front portions of the second and third stocker trays 17 and 18 with respect to the front portion of the first stocker tray 16 are different from T1 and T2, and the first to third stocker trays 16 to 18 are respectively positioned forward. The portions project diagonally upward in parallel and stepwise with different amounts of projection.

FIGS. 16A and 16B are explanatory diagrams (fourth) of the operation of the stocker mechanism. This figure shows the base frame 1

Only slide to the final position forward, where the first
The third to third stocker trays 16 to 18 project to the front of the chassis 11 to reach the MD cartridge insertion / removal position where the MD cartridge M (see FIG. 1) can be inserted / removed. (A) shows the right chassis 22 side, and (b) shows a state where the right chassis 22 is removed.

In FIG. 16A, the base frame 1
2 is a moving distance A3 forward from the standby position indicated by a white arrow.
Just slide horizontally to the final position forward. The pin 25b of the right sub-frame 25 passes through the horizontally long hole 15b of the cam plate 15, and
Has moved to the lower end position of the inclined groove in the cam groove 22c, the pin 25b slides forward by the moving distance A3 indicated by the outline arrow and moves toward the lower mounting surface G direction. Sliding by C2 has reached the final position forward.

In FIG. 16B, the base frame 1
2 indicates that it remains parallel to the mounting surface G.
When the pin 25b of the sub-frame 25 slides by the movement distance C2 (see a) with respect to the mounting surface G, the sub-frame 13 swings clockwise in the drawing around the fulcrum 25a and obliquely upwards with respect to the mounting surface G. It indicates that the inclination is α2 toward the camera. Also, the pin 25b of the sub-frame 25 is moved
2 (see a), slide the cam plate 15
Indicates that β2 swings clockwise in the figure around the fulcrum 12i. Also in this case, when the sub-frame 13 is inclined obliquely upward by α2, the upper first stocker tray 16 fixed to the sub-frame 13 also
Α2 toward the upper side diagonally with respect to the mounting surface G
Lean. On the other hand, when the cam plate 15 is inclined by β2, the front pins 31g, 31g and the rear pins 31h, 31h fixed to the middle and lower second stocker trays 17, 18, respectively.
Slides forward and backward along the oblong holes 25d and 25e in the front and rear of the right sub-frame 25 in the same manner as in the previous figure (FIG. 15).
The amount of movement of 1g and the rear pins 31h, 31h depends on the distance from the fulcrum 12i of the cam plate 15 to the pins 31h, 31h of each stage, and the amount of movement of the third stocker tray 18 below the second stocker tray 17 at the middle stage. Is larger. Therefore, the front portions of the second and third stocker trays 17 and 18 are different from the front portions of the first stocker tray 16 in the projection amounts T3 and T4.

That is, the inclination α2 of the sub-frame 13 is an inclination with respect to the mounting surface G of the first to third stocker trays 16 to 18, and the projection amount T3 is the first stocker tray 16
And a step between the second stocker tray 17 and the protrusion amount T4
Is a step between the first stocker tray 16 and the third stocker tray 18. Therefore, the first to third stocker trays 16
18 project in parallel and diagonally upward stepwise with different amounts of projection at the front part. In this state, when the MD cartridge M is inserted into the first to third stocker trays 16 to 18 from the normal insertion direction, the rear surface MB of the MD cartridge M projects from the front part of each stocker tray 16 to 18 by the dimension L0, and The rear surface MB of the MD cartridge M of each stage also protrudes obliquely upward in a stepwise manner.
The left and right sides can be easily grasped with fingers, and the state shown in FIG. 1 is obtained.

As described above, since the sub-frame 13 is swingably mounted on the base frame 12, the MD cartridge M (see FIG. 1) can be taken out at an angle. The second stocker tray 17 is a plate attached to the base frame 12 so as to be swingable separately from the subframe 13, and swings together with the subframe 13 so that the second stocker tray 17 has a different pushing amount depending on the distance from the swing center. Further, since the cam plate 15 for pushing the third stocker tray 18 forward is provided, the front portions of the first to third stocker trays 16 to 18 can be respectively shifted to form a step-like shape. ~ M mounted on the third stocker trays 16-18
The back surface of the D cartridge M is stepped. Therefore, the first to first
When the MD cartridges M (see FIG. 1) mounted on the third stocker trays 16 to 18 are exchanged, the left and right side surfaces of the MD cartridges M can be gripped separately, so that the insertion / removal operation of the MD cartridges M is good. Become.

FIGS. 17A and 17B are explanatory diagrams (fifth) of the operation of the stocker mechanism. FIG. 16 (a),
At the MD cartridge insertion / removal position shown in (b), the MD cartridge M (see FIG.

Passes through the standby position, and further slides from the standby position to the rear mini-disc reproducing apparatus K side indicated by a white arrow by the moving distance B1 to reach the final rear position, where the MD cartridge of a desired stage is located. M is the mini disc player K
This indicates that the loading position for loading (pulling out) has been reached. (A) shows the right chassis 22 side, and (b) shows a state where the right chassis 22 is removed.

In FIG. 17A, the base frame 1
The second pin 12d and the second pin 12e are guided by the horizontally long grooves 22a and 22b formed in the right chassis 22, and slide horizontally from the standby position to the rear side of the mini-disc reproducing apparatus K indicated by a white arrow by the moving distance B1, and , Right subframe 2
Since the pin 25b of No. 5 slides horizontally from the standby position along the horizontally long groove of the cam groove 22c of the base frame 12 to the side of the mini disc reproducing device K on the rear side indicated by an outline arrow by the moving distance B1, The frame 13, the cam plate 15, and the first to third stocker trays 16 to 18 have reached the loading position without swinging with respect to the base frame 12. FIG. 17 (b) shows the base frame 12, the sub-frame 13, the cam plate 15, and the first
7 shows the third stocker trays 16 to 18 at the loading position.

Next, the operation of the erroneous insertion detection mechanism 50 will be described step by step with reference to FIGS. First, an aspect in which the MD cartridge M is inserted into the first (to third) stocker tray 16 (to 18) will be described with reference to FIGS.

FIGS. 18A and 18B are explanatory views showing a state where the MD cartridge is inserted into the first (-third) stocker tray from the normal insertion direction in the recording medium stocker apparatus according to the present invention. is there. In FIG. 18A, M1
Is a left groove of the MD cartridge M, M2 is a right groove for opening and closing the shutter of the MD cartridge M, M3 is a shutter of the MD cartridge M, MF is a front surface of the MD cartridge M in a normal insertion direction, and MB is a rear surface of the MD cartridge M. , ML
Denotes a left side surface of the MD cartridge M, and MR denotes a right side surface of the MD cartridge M. The MD cartridge M has a width W (W = 71.4 mm) and a depth D (D = 6).
8 mm) according to the standard, and the depth dimension D (D = 68 mm) is the width dimension W (W = 71.4 mm)
Since the setting is slightly smaller than that of the MD cartridge M, although a mark indicating the insertion direction is displayed on the upper surface of the MD cartridge M, some users may mistakenly insert the MD cartridge M into the proper insertion direction without knowing this. An erroneous insertion may occur, for example, when the M cartridge M is inserted with the left and right sides reversed, or when the MD cartridge M is inserted with the left side or the right side at the top. Therefore, when the MD cartridge M is erroneously inserted, the erroneous insertion detection mechanism 50 is provided to detect the erroneous insertion and immediately take out the erroneously inserted MD cartridge M. Here, the first (~~ third) stocker tray 16 (~ 18)
The right and left side surfaces ML and MR in the width direction of the MD cartridge M are aligned with the right guide surface 3 of the first stocker tray 16.
The normal insertion direction of the MD cartridge M is when guided by the left guide surface 1a and the left guide surface 31b. At this time, M
The end of the left groove M1 of the D cartridge M is the left lock lever 3
In this case, the MD cartridge M has been stopped by hitting the lock portion 33b of No. 3. In this state, the rear surface MB of the MD cartridge M is positioned at L0 from the front portion of the first stocker tray 16.
Left and right sides ML, M of the MD cartridge M
R can be easily grasped with fingers. Note that S indicates a reference line on the back surface MB when the MD cartridge M is properly inserted.

FIG. 18B shows that the MD cartridge M is inserted into the first (-third) stocker tray 16 (-18) from the normal direction, but the MD cartridge M is in the first position.
This shows a case where it is not completely inserted into the stocker tray 16. At this time, a gap L1 is generated between the end of the left groove M1 of the MD cartridge M and the lock portion 33b of the left lock lever 33. As a result, the rear surface MB protrudes from the reference line S by the gap L1. (Protruding).

FIGS. 19 (a) and 19 (b) are explanatory views showing a state where the MD cartridge is inserted into the first (-third) stocker tray from the wrong direction in the recording medium stocker apparatus according to the present invention. . FIG. 19A shows a case where the left and right side surfaces ML and MR of the MD cartridge M are reversed and erroneously inserted into the first stocker tray 16 while being turned upside down. At this time, the right groove M2 of the MD cartridge M and the left lock lever 3
3 does not match the height of the lock portion 33b, and the MD cartridge M stops at the lock portion 33b. As a result, this indicates that the back surface MB has protruded from the reference line S by the length L2. FIG. 19B shows that the front direction MF and the rear surface MB in the depth direction of the MD cartridge M are guided by the right guide surface 31a and the left guide surface 31b of the first stocker tray 16 by changing the insertion direction of the MD cartridge M by 90 °. It shows the case of incorrect insertion. In this case, since the depth dimension D (D = 58 mm) of the MD cartridge M is smaller than the dimension between the right guide surface 31a and the left guide surface 31b, rattling occurs on the left and right. Therefore, when the MD cartridge M is inserted obliquely, the left groove M2 of the MD cartridge M and the lock portion 33b of the left lock lever 33 hit, and the insertion direction of the MD cartridge M and the direction of the left groove M2 are different. The cartridge M stops at the lock portion 33b. As a result, this indicates that the left side surface ML has protruded the length L3 from the reference line S. Further, in the above, even when the MD cartridge M is inserted almost straight without being inserted obliquely,
Since the width dimension W (W = 71.4 mm) is in the front-rear direction, the length becomes longer than that at the time of normal insertion, so that it protrudes from the reference line S.

FIG. 20 is an explanatory view (first) of the operation of the erroneous insertion detection mechanism, and is a plan view showing a state where the MD cartridge M is inserted from a normal direction at the MD cartridge insertion / removal position. When the left and right side surfaces ML and MR of the MD cartridge M are guided and inserted into the right guide surface 31a and the left guide surface 31b of the first (-third) stocker tray 16 (-18) at the MD cartridge insertion / removal position. First, Fig. 18
This is a state where the MD cartridge is inserted from a normal direction as described in (a). Here, the shutter portion 51e of the shutter is retracted to the left, the gap δ between the shutter portion 51e of the shutter 51 and the left side surface ML of the MD cartridge M is δ1, and the shutter 51 is
Not hit. Then, insert the MD cartridge M into the first
(-Third) After the stocker tray 16 (-18) is completely inserted from the normal direction, it is moved to the standby position.

FIG. 21 is an explanatory view (second) of the operation of the erroneous insertion detection mechanism, and is a plan view and a perspective view showing a state where the MD cartridge M inserted from a normal direction reaches the standby position. When the MD cartridge M is completely inserted into the first (to third) stocker tray 16 (to 18), first, as shown in FIG.
As described in (a), although the rear surface MB of the MD cartridge protrudes from the front part of the first stocker tray 16 by the dimension L0, the rear surface MB of the MD cartridge is retracted from the back side of the shutter 51, that is, protrudes. The dimension L0 is set to a dimension that does not affect the movement of the shutter 51. Accordingly, since there is a gap μ1 between the back surface MB of the MD cartridge M and the back surface of the shutter portion 51e of the shutter 51, the shutter 51 can be moved rightward from the MD cartridge insertion / removal position. Is shielded from the back surface MB. Therefore, after the shutter 51 shields the back surface MB of the MD cartridge M,
Prevent insertion of a new MD cartridge M, ie, MD
The double insertion of the cartridge M is prevented.

FIG. 22 is an explanatory view (third) of the operation of the erroneous insertion detection mechanism, and is a plan view showing a state where the MD cartridge M is inserted from an incorrect direction at the MD cartridge insertion / removal position. When the front surface MF and the back surface MB of the MD cartridge M are guided and inserted into the right guide surface 31a and the left guide surface 31b of the first (-third) stocker tray 16 (-18) at the MD cartridge insertion / removal position. First, FIG.
This is a state where the MD cartridge is inserted from the wrong direction as described in (b). Here, for example, the back surface MB of the MD cartridge M is connected to the right guide surface 3 of the stocker tray 16.
1a, the gap δ between the shutter portion 51e of the shutter 51 retracted leftward and the front surface MF of the MD cartridge M becomes δ2. Then, the MD cartridge M is moved to the standby position integrally with the first (-third) stocker tray 16 (-18) while being inserted from the wrong direction.

FIG. 23 is a view for explaining the operation of the erroneous insertion detection mechanism (fourth), and is a plan view and a perspective view showing a state where the MD cartridge M inserted from an incorrect direction has reached the standby position. When the MD cartridge M is inserted into the first (to third) stocker tray 16 (to 18) from the wrong direction, the left side surface ML of the MD cartridge M is properly set as described above with reference to FIG. Reference line S of back MB when inserted
Extruded more. When the left side surface ML of the MD cartridge M reaches the standby position while protruding from the reference line S, when the shutter 51 moves rightward from the MD cartridge insertion / removal position, the shutter unit 51 of the shutter 51
e collides with the protruding portion on the front side MF side of the MD cartridge M, and the shutter 51 cannot move to the right any more, whereby it is possible to detect that the MD cartridge M is erroneously inserted. . At the time of this collision, the shutter 5
Since the load on the drive mechanism 60 for driving the drive mechanism 1 becomes large, an excessive current value of the drive mechanism 60 is detected at this time. It is only necessary to return to the retracted position of the cartridge insertion / removal position and remove only the MD cartridge M that has been erroneously inserted. At this time, the shutter portion 51e of the shutter 51 is in the first position.
Since the third stocker trays 16 to 18 have a length equal to the number of stages, erroneous insertion of the MD cartridge M can be detected at any stage in a batch.

Note that, as described with reference to FIG.
When the cartridge M is inserted from a normal direction, but is not completely inserted and the back MB protrudes, or as described in FIG. 19A, the left and right side surfaces ML and MR of the MD cartridge M are reversed. When the back MB protrudes when inserted, the shutter 5
It can be detected by the collision of one shutter unit 51e.

In the embodiment, the recording medium is described as an MD cartridge. However, the recording medium is not limited to the MD cartridge, but includes a stocker mechanism for a recording medium such as a compact disk, a digital video disk, or a cassette tape.
