Abstract

PURPOSE:To load and unload the cartridge in and from a holder which has two pockets while selecting a pocket properly with simple constitution by switching the oscillation positions of a 1st and a 2nd support means by a cam means associatively. CONSTITUTION:When the cartridge is taken in an upper holder pocket, a spline shaft 40 is rotated by an upper rotary solenoid S1 as shown by an arrow H. Simultaneously, the other spline shaft 40' is rotated through a transmission shaft 46 as shown by the arrow H. Consequently, upper cam members 41 and 41' rotate upper swing arms 8 and 8' to their operation positions respectively. Consequently, an outward feed roller 7a for the upper pocket clamps both sides of the tip part of the cartridge. At this time, lower swing arms 23 and 23' are still at stand-by positions.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a holder mechanism for a disk cartridge, and particularly to a holder having two pockets, in which a pocket is appropriately selected to insert and remove a disk cartridge. The present invention is applied, for example, to a disk cartridge transport mechanism installed in an optical disk library device or the like.

[Conventional technology]

Optical disk cartridge C (hereinafter referred to as cartridge)
As shown in FIG. 6, the optical disk library device that stores and drives the cartridges includes a storage rack 2 that stores a plurality of cartridges, a drive 3 that drives the cartridge 1, and a storage rack 2 and drive 3 that stores the cartridge 1. A disk cartridge conveyance device 4 is provided for conveying the disk cartridge between the two. In this optical disk library device, a storage rack 2 and a drive 3 are arranged on one side (one side) of the transport device 4. The transport device 4 takes in the cartridge 1-ridge 1 from the storage rack 2 or the drive 3, and transfers the cartridge 1 to the storage rack 2 while holding the cartridge 1.
The holder mechanism HB includes a holder 6 that can move up and down between the drive 3 and the drive 3.

That is, in this holder mechanism HB, the holder 6
As shown in FIG. 7, the cartridge 1 to be transported is taken in and the transported cartridge 1 is sent out from an end opening 6a formed at one end facing the storage rack 2 and the drive 3. It has become. The holder 6 is supported by a base frame 5 disposed around it via a rotating shaft 16, and is connected to an elevating drive means M (such as a motor) via an endless belt (not shown).
6), when the base frame 5 is moved up and down along the transport guide G, the cartridge 1 is transported by moving up and down integrally with the base frame 5. Further, the holder 6 is rotatable by 180 degrees with respect to the base frame 5 by a rotating shaft 16 so that the recording surface of the cartridge 1 accessed by the read head of the drive 3 can be reversed.

Furthermore, this holder mechanism HB includes the holder 6 as described above.
The 8th
As shown in the figure, the end openings 6a on both sides of the holder 6
A pair of outward feed rollers 7, 7 provided so as to be located further outward.

1 provided so as to be located at the center portion on both sides of the holder 6
A pair of central feed rollers 10, 10 are provided. The outward feed rollers 7, 7 are rotatably supported at one end by the other end of swing arms 8, 8 which are swingably attached to the base frame 5 via shafts 9, 9. Similarly,
The central feed roller 10.10 has a shaft 11.10 at one end.
It is rotatably supported by the other end of a swinging arm 13.13 which is swingably attached to the base frame 5 via 11. In addition, each swing arm 8,13.

It swings between an operating position in which each of the feed rollers 7 and 10 contacts the cartridge 1 that is taken in and out of the holder 6, and a standby position in which each of the feed rollers 7 and 10 does not contact the cartridge 1. It is something that will be done. Further, the swinging of each swinging arm 8, 13 is performed by driving means DRI, DR2, which is provided for each swinging arm 8, 13 and is composed of a solenoid, a spring, and the like.

In this holder mechanism HB, when the cartridge 1 is taken into the holder 6 from the drive 3, first, the swing arms 8, 8 are rotated from the standby position to the operating position by the drive means D R1, DRI. The outer feed rollers 7, 7 approach each other while pinching the tip of the cartridge 1 protruding from the drive 3, and rotate by appropriate means, so that the tip of the cartridge 1 is inside the holder 6. Feed until it reaches approximately the center position. Therefore, as the swing arms 8, 8 are returned to their original standby positions by the drive means DRI, DRI, the outward feed rollers 7, 7 also retreat from the cartridge 1 while separating from each other. At the same time, the swing arm 13.
13 is rotated from the standby position to the operating position by the driving means DR2, DR2, the center feeding roller 1
0° 10, while approaching each other, rush into the holder 6 through side openings 6b, 6b formed on both sides of the holder 6, and clamp the tip of the cartridge 1.

By rotating by appropriate means, the cartridge 1 is taken into the holder 6 to a predetermined position as shown by the two-dot chain line. When the cartridge 1 is taken into the holder 6 in this way, the swinging arms 13° 13 are returned to the initial standby position by the driving means DR2, DR2, and the center feeding rollers 10, 10 They also retreat from Car 1-Ridge 1 while separating from each other. Note that when the cartridge 1 that has been taken into the holder 6 and transported in the above manner is sent out from the holder 6 to, for example, the storage rack 2, the cartridge 1 is transported in the order opposite to the above-mentioned order.
It is first fed out by central feed rollers 10, 10 and then by outward feed rollers 7, 7.

In addition, as a holder for transporting the cartridge 1 as described above, as shown in FIG. 9, for example, two holders 6 shown in FIG. There is a double pocket type holder 52 which is provided with two holding parts capable of holding one cartridge 1, that is, an upper holder pocket Pa and a lower holder pocket PB. Incidentally, the holder 6 is a one-pocket type holder. In the holder mechanism using this double pocket type holder 52, for example, when replacing the cartridge 1 driven by the drive 3, the cartridge 1 is taken into the empty upper holder pocket Pa from the drive 3, and the same cartridge is replaced. (i.e., the cartridge 1 is placed in the storage rack 2)
It is now possible to send out the other cartridge 1 to the drive 3 from the lower holder pocket pb holding the other cartridge 1 without having to return it to the holder 6 using the one-pocket type holder 6. This means that work efficiency can be improved compared to mechanism HB. Therefore, in the holder mechanism using the holder 52, the cartridge 1 can be inserted into and removed from each of the upper holder pocket Pa and the lower holder pocket PB, and either of the holder pockets Pa and Pb can be moved as appropriate. The configuration is such that the cartridge 1 can be selectively inserted or removed.

[Problem to be Solved by the Invention] However, in the holder mechanism, in order to be able to appropriately select one of the holder pockets Pa and Pb, each holder pocket Pa and Pb must be selected as appropriate.
It is necessary to selectively operate the outward feed roller pairs, one pair provided for each b, and each swinging arm supporting one outward feed roller must also be selectively swung. . This selective rocking of each rocking arm is
This can be achieved by providing a drive means such as a solenoid for each swing arm 11, but in this case, the structure of the holder mechanism becomes complicated and it becomes difficult to control each drive means accurately.

This invention has been made in view of the above-mentioned points, and it is an object of the present invention to easily and easily insert/remove a cartridge into a holder having two pockets by selecting the pocket appropriately. The purpose of the present invention is to provide a disk cartridge holder mechanism that allows for the following functions.

[Means to solve the problem]

In order to achieve the above object, the holder mechanism according to the present invention includes:
A holder consisting of two side-by-side pockets for holding a disc cartridge in and out, and a first pocket for taking the disc cartridge in and out of one of the pockets.
a second feeding means for moving the disk cartridge into and out of the other pocket; and a second feeding means for moving the disk cartridge into and out of the other pocket; The first support means is pivotably supported between a standby position and a standby position, and the second feeding means is pivoted between an operating position in which the feeding means acts on the disk cartridge and a non-acting position. The second support is swingable between the standby position and the standby position.
a support means, a cam means for switching the position of each support means in conjunction with each other so that at least one of the support means is in an operating position and the other is in a standby position, and a drive means for driving the cam means. and one of the first and second feeding means selectively acts on the disk cartridge in response to driving of the cam means by the drive means, and selects a pocket into which the disk cartridge is to be inserted or removed. This is what I did.

[For production]

The first and second feeding means are oscillated by corresponding first and second supporting means between an operating position in which they act on the disc cartridge in the respective pocket and a standby position in which they do not act on the disk cartridge in the corresponding pocket. movably supported.

The first and second support means are moved in conjunction by cam means and their positions are switched such that when at least one of the support means is in the operating position, the other is in the standby position. The cam means is driven by the drive means.

Therefore, when it is desired to insert or remove a disc cartridge from a desired one of the two pockets in the holder, the driving means drives the cam means, and the supporting means (for example, the first supporting means) corresponding to the desired pocket is driven by the driving means. ) is in the operating position. At this time, the other support means (second support means) becomes standby mode 1δ in conjunction. The first support means set in the operative position causes the corresponding first feeding means to act on the disc cartridge at the desired indentation I.

On the other hand, in the other pocket I-, the corresponding second support means is in the standby position, so that the corresponding second feeding means does not act on the disk cartridge in the pocket I-. In this way, the disc cartridge can be taken out and put into the desired pocket.

As described above, in the holder mechanism according to the present invention, since the swinging positions of the first and second supporting means are switched in conjunction with each other by the cam means, one driving means corresponding to the cam means is driven. The selection of the pocket into which the cartridge is to be inserted or removed can be made by means of the chisel.

Further, a gear 28a is fixed to a portion of each shaft 9 below the upper swing arm 8, and the gear 28a is rotated by rotation of a spline shaft 30 extending through the base frame 5. In the illustrated example, only the spline shaft 30 on one side of the holder 56 is rotated by the motor RM as a rotational drive source, and the spline shirts 1 to 30 are rotated by the motor RM as a rotational drive source. The episode Ji? The movement is transmitted to the spline shirt 1-30' on the other side via an endless belt 29 shaped like an "8". In this way, this other side spline shirt] -30'' rotates in the opposite direction to the central spline shaft 3o of said force.Furthermore, in each said tliJI9.

A gear 28b is fixed to a portion above the lower swing arm 23, and the gear 28b is connected to a drive gear 31 which is rotated by rotation of the spline shaft 3o.
It is engaged with b. In this way, as the drive gear 31a is rotated by the spline shaft 30, each upper pocket outward feed roller 7a is rotated by the gear 28a,
Shaft 9, pulley 26a, endless belt 27a, pulley 24a
and rotates via the axis L6a.

Further, as the driving gear 31b is rotated by the spline shaft 3QJ, each lower pocket circumferential outward feeding roller 7b is rotated via the gear 28b, the shaft 9, the pulley 26b, the endless bells 1 to 27b, the pulley 24b and the shaft 16b. It is designed to rotate.

A roller 8a is provided on the upper surface of the upper swinging arm 8, and the roller 8a is inserted into and fixed to a spline shaft 40 extending through the base frame 5, and is always attached to an upper cam member 41 located outside the arm 8. Being forced. Further, a roller 8b is provided on the lower surface of the lower swing arm 2, and the roller 8b is always pressed against a lower cam member 42 that is inserted into and fixed to the spline shaft 40 and located on the outside of the arm 21. . The upper cam member 41 and the lower cam member 42 are connected to the spline shaft 4.
They are fixed to the spline shaft 4o in opposite directions so as to form an angle of approximately 180 degrees in the horizontal direction with 0 as the center. Furthermore, the upper cam members 41, 41' facing each other on both sides of the upper holder pocket Pa are fixed to their respective spline shafts 40, 40' in opposite directions so as to form an angle of approximately 180 degrees in the horizontal direction. Similarly, the opposing lower cam members 42, 42' are secured to their respective spline shafts, 40, 40', in opposite directions at approximately 180 degrees horizontally. Each cam member 41.41'42.42' rotates with the corresponding endless belt 27a, 27a', 27b, 27b' and swing arm 8,8''21 as the spline shirt 1 to 40.40' rotates. .21' so that the rollers 8a, 8a', 8b, 8b' can be pressed.In addition, when the base frame 5 is moved up and down by the elevating drive means M, the conveyance Guide G and the spline shaft 30.30', 40.40
' It is designed to slide against.

Further, a spring 44 whose end is fixed to the base frame 5 is attached to the outside of each swing arm 8, 21, and the spring 44 always keeps each swing arm 8, 21 in a standby position. It is strong.

That is, the rollers sg and 8b are connected to the corresponding cam member 4.
I am always pushing towards 1.42. In addition, in the illustrated example, the spline shaft 40 on one side of the holder 50
is connected at its upper and lower ends to an upper rotary solenoid S1 and a lower rotary solenoid S2. The upper rotary solenoid S1 rotates the spline shaft 4o in the direction of arrow H, and the lower rotary solenoid S2 rotates the spline shaft in the direction of arrow □1.
It rotates in the direction. The solenoid SL.

When the spline shaft 40 is rotated in either direction by S2, the rotational movement of the spline shaft 40 is transmitted to the spline shaft 40' on the other side of the holder 5o via the transmission shaft 46. .

In this way, the spline shaft 40 on the other side

In this holder mechanism HA, for example, when the spline shaft 40 is rotated in the direction of arrow H by the upper rotary solenoid S1, the upper cam member 41 on one side of the holder 50 does not rotate in the direction of arrow H. By pressing the roller 8a, the upper swinging arm 8 is rotated to the operating position against the biasing force of the spring 44. At this time, the same spline shaft 4 as the upper cam member 41
The lower cam member 42, which is fixed at zero, does not rotate and retreats from the roller 8b. Therefore, the lower swing arm 21 remains in the standby position. At the same time, on the other side of the holder 50, the spline shirt I-40' is rotated in the direction of arrow H through the transmission shirt 1-46, so that the spline shirt I-40' is rotated by 180 degrees with respect to the upper cam member 41. The upper cam member 41', which is provided at an angle of , rotates in the direction of arrow H and suppresses the roller 8a', thereby moving the upper swinging arm 8' against the biasing force of the spring 44. Rotate into position. At this time, the lower cam member 42', which forms an angle of 180 degrees with respect to the lower cam member 42, does not rotate in the direction of arrow H but separates from the roller 8b'.
The lower swinging arm 21' remains in the standby position. In this way, the upper swing arms 8 provided on both sides of the holder 50
, 8' are rotated to the operating position, the upper pocket outer feed rollers 7a, 7a' can grip the cartridge 1 and feed the cartridge 1.

When said upper rotary solenoid S1 is turned off, each swinging arm 8, 8' is energized by a spring 44, 44.
It returns to the standby position by the urging force of. During this return, the roller 8a.

8a' rotates the respective upper cam member 41, 41' and thus the splined shaft 40, 40' into its initial position.

Further, in the illustrated example, when the spline shirt 1-40 is rotated in the direction of the arrow 1 by turning on the lower rotary linenoid S2, the lower cam members 42, 42' are rotated in the direction of the arrow and the rollers are rotated. By pressing 8b, 8b', the lower swing arm 21, 21' is rotated to the operating position against the biasing force of the spring 44. In this way, the lower pocket circumferential outward feeding rerolling rollers 7b, 7b can grip the cartridge 1 and feed the cartridge 1. In addition, at this time, the upper swing arm 8.8
' remains in the standby position.

Center feeding reroller 10a4 for each upper pocket 11. It is now able to swing on the upper surface side of the base frame 1, 5 about the shaft 11 passing through the C base frame 5. It is rotatably supported at the tip of the movable arm 13 via a shaft 37a. In addition, each lower pocket center feed roller 10b
m is attached to the tip of the swinging arm 23 which can swing around the shaft 11 on the lower surface side of the base frame 5.
It is rotatably supported via 37b. Upper pocket 1
The center feed roller 10a for ~ and the center feed roller 10b for lower pockets 1 ~ also rotate with substantially the same configuration as the above-mentioned upper pocket outer feed roller 7a and lower pocket outer feed roller 7b. That is, the upper pocket central feed roller 10a is connected to the spline shaft 30.
As the drive gear 31a is rotated by the drive gear 31a, the gear 32a driven by the drive gear 31a and the shaft 11. It rotates via a pulley 34a, an endless belt 35a, a pulley 36a, and a shaft 37a. In addition, as the drive gear 31b is rotated by the spline shaft 30, the lower pocket central feed roller 10b includes a gear 32b, a shaft 11, a pulley 34b, an endless belt 35b, a pulley 36b, and a shaft 11, which are driven by the drive gear 31b. It is adapted to rotate via a shaft 37b. Further, each of the swing arms 13, 23 is rotated to the operating position when the respective solenoid S is turned on, and returned to the standby position by the biasing force of the spring 38 when the solenoid S is turned off. By rotating the swinging arms 13 and 23 to the operating position as described above, the upper pocket center feed roller loa and the lower pocket center feed roller 10b move to the respective holder pockets Pa and P.
The cartridge 1 is fed by passing through the side openings 20b, 20b formed in the side openings 20b, and entering the corresponding holder pockets Pa, Pb.

As shown in FIG. 1, on both sides of the second storage rack 2B located at the other end of each holder 50, there are the upper pocket outer feed rollers 7a, 7a and the lower pocket outer feed roller 7b. , 7b, a pair of upper pocket outer feed rollers 48a, 48a' and a pair of lower pocket outer feed rollers 48a, 7b (in FIG. 3, upper pocket outer feed rollers 48a, 7b). 48a' only is shown). Outward feed rollers 48a, 4
The outer feed rollers 8a' and the lower pocket outer feed rollers operate with the same structure as that described for the outer feed rollers 7a, 7a', 7b, and 7b'. In this way, in the holder mechanism HΔ, not only is the cartridge 1 inserted and removed between the drive 3 or the first storage rack 2A and the respective holder pockets Pa and Pb, but also the cartridge 1 is inserted into and removed from the second upper pocket. The cartridge 1 is also taken in and out between the second storage rack 2B and the respective holder pockets Pa and Pb by the outward feed rollers 48a, 48a' for ~ and the outward feed roller for the second lower pockets 1~. It looks like this.

Hereinafter, an example of the operation of the holder mechanism HA according to the present invention will be explained with reference to FIG.

First, when the cartridge 1 is taken into the upper holder pocket Pa from the first storage rack 2A, for example, the spline shaft 40 on one side of the holder 50 is rotated in the direction of arrow H by the upper rotary solenoid S1, and at the same time, the transmission When the spline shirts I to 40' on the other side of the holder 50 are rotated in the direction of arrow H via the shaft 4G, the upper cam members 41.41' move the respective upper swinging arms 8.8' to the operating position. Rotate it.

Therefore, the outer feeders 7a, 7a for the upper pocket h clamp both sides of the leading end of the cartridge 1 protruding from the first storage rack 2A. Note that at this time, the lower swing arm 23,
23' remains in the standby position. Next, the spline shirt 1-30 is rotated by the motor RM, and at the same time, the spline shaft 30' is rotated through the endless belt 29.
is rotated, the drive gears 31a, 31a'
starts to rotate, and therefore, the upper pocket peripheral outer feed rollers 7a, 7a' and the upper pocket center feed roller 1
0a and loa' also begin to rotate. By such rotation of the upper pocket peripheral outward feeding rollers 7a, 7a'', the cartridge 1 is taken in to the approximate center position of the upper holder pockets 1 to Pa. In this way, the cartridge 1 is taken in to the approximate center position of the upper holder pocket Pa. When the upper rotary solenoid S1 is turned off, the upper swinging arms 8a, 8a' return to the standby position by the biasing force of the springs 44, 44'. is the cartridge 1
retreat from.

Next, the solenoid S turns on and the upper swing arm 13.13
' rotates to the operating position. In this way, the cartridge 1 is held by the upper pocket peripheral outer feed rollers 10, 10' rotating as described above, and is taken into a predetermined position in the upper holder pocket Pa.

The cartridge 1 taken into and held in the upper holder pocket Pa as described above is integrated into the holder 50 with the base frame 5 moved by the elevating drive means M.
By moving, it is transported to the drive 3, for example. When transported to the drive 3 in this manner, the cartridge 1 is first moved by the upper pocket central feed rollers 10a, +10a'.
Next, it is sent out by the upper pocket outward sending rollers 8a, 8a'. At this time, each of the feed rollers 10a, 10a' 8a, 8a' is rotated in the opposite direction to the direction in which the cartridge 1 was taken into the upper holder pocket l-Pa as described above.

Further, for example, when the cartridge 1 is loaded from the first storage rack 2A to the lower holder pocket pb, the lower rotary lenoid S2 is turned on, so that the spline shaft 40, 40' is rotated in the direction of the arrow 1, Along with this, the lower cam member 42.42'
is rotated in the direction of the arrow ■. In this way, the lower swinging arm 21.21' is rotated into the operating position and the cartridge 1 is transferred to the lower pocket outer feed rollers 7b, 7b'.
is taken into approximately the middle position of the lower holder pocket pb. Thereafter, the cartridge 1 is taken into a predetermined position in the lower holder pocket pb by the lower pocket central feed roller 10b, lob'.

In this embodiment, in order to reduce the heavy electric current in the holder mechanism, the drive is provided from outside the holder mechanism via the spline shafts 40 and 40', but the drive source may be mounted in the holder mechanism.

Note that the holder mechanism HA according to the present invention is not limited to the one described above, and can be used in the transport device of an optical disk library device in which a storage rack and a drive are provided only on one side of the disk cartridge transport device. Good too. Furthermore, the holder mechanism does not need to be incorporated into the transport device. That is, the present invention can be applied even to devices that do not have a transport function.

Further, this holder mechanism HA can be used not only in a disk cartridge transport device of an optical disk library device, but also in a device that transports a magneto-optical disk cartridge or other information medium disk cartridge.

Furthermore, the cam means in the present invention is not limited to rotary cams, but includes linear motion cams (i.e. protrusions) and other cams in which the positions of protrusions or recesses cannot be switched in response to displacement.

〔Effect of the invention〕

As described above, according to the present invention, the cam means swings both the first and second support means so that when one of the first and second support means corresponding to two pockets is in the operating position, the other is in the standby position. Since the moving position is switched in conjunction with each other,
By only driving one drive means corresponding to the cam means, it is possible to select the pocket into which the cartridge is to be inserted or removed. As a result, the holder machine 4 according to the present invention
11 has an excellent effect in that it has a simple structure and allows the cartridge to be taken in and out by appropriately selecting the pocket for a holder having two pockets.
