The transport device 4 includes a holder 6 that takes in the cartridge 1 from the storage rack 2 or the drive 3 and is movable up and down between the storage rack 2 and the drive 3 while holding the cartridge 1.

That is, as shown in FIG.
The cartridge 1 is taken in and the transported cartridge 1 is sent out. Moreover, this holder 6 is
It is supported by a base frame 5 disposed around the base frame 5 via a rotating shaft R, and is driven by a lifting/lowering driving means M (see FIG. 4) such as a motor via an endless belt or the like (not shown).

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 rotated by a rotation axis R at a 180° angle with respect to the base frame 5 so that the recording surface of the cartridge 1 accessed by the head of the drive 3 can be reversed.
It can be rotated by degrees.

Furthermore, this conveying device 4 is configured to transport cartridges in and out (feed and take in) between the holder 6 and the storage rack 2 or drive 3 as described above.
A pair of outward feed rollers (hereinafter referred to as pick rollers) 7a and 7b are provided so as to be located outward from the entrance/exit port 6b on both sides of the holder 6; A pair of Chuo Expressway Rerollers 10a.

Alternatively, at the point immediately before being introduced into the storage slot S, only the end portion thereof is guided by the aforementioned inner wall surface, and reliable guidance is not performed.

[Problem to be solved by the invention]

However, as mentioned above, the solenoid SL.

The pick rollers 7a, 7b are moved to the cartridge 1 by rotating the swinging arms 8a, 8b to the operating position by the SL.
In this type of conveying device that presses the
The points at which L and SL are turned on are not necessarily the same, and
The powers of the solenoids SL and SL are not necessarily the same. Further, the swing arms 8a and 8b are not necessarily provided so as to be symmetrical about the holder 6 (that is, have the same inclination angle with respect to the holder 6) when in the standby position. Therefore, both the big rollers 7a and 7b are not positioned symmetrically with respect to the holder 6. For this reason, one pick roller 7
The timing and the pressing angle (therefore, the pressing force) when the pick rollers a and 7b press against both sides of the cartridge being taken in and taken out from the holder 6 are also different between the pick rollers 7a and 7b. For the reasons mentioned above, the cartridge 1 transferred by both pick rollers 7a and 7b is placed between the holder 6 and the drive 3 or the storage slot S.
There will be a tilt in the transfer posture (tilt with respect to the holder 6) at the point immediately before the introduction between the cartridges 1 and 2, and if such a tilt is severe, it will be particularly difficult to take the cartridge 1 into the holder 6 from the drive 3 or the storage slot S. A situation has arisen in which it is no longer possible to do so (1 (b) in Figure 4).
reference).

Further, in the transport device of the optical disk library device, it is difficult to stop the holder 6 in a state where it is completely facing the drive 3 or the storage slot S.
As shown in the figure, the cartridge entrance/exit 6b of the holder 6, the cartridge entrance/exit 3b of the drive 3, or the storage slot S
The cartridge entrance/exit sb is tilted or misaligned relative to the cartridge entrance/exit sb. In this case, the cartridge 1 stored in the drive 3 or storage slot S will also be tilted or misaligned with respect to the holder 6. If such tilting or misalignment is severe, the cartridge 1 stored in the drive 3 or storage slot S will be tilted or misaligned with respect to the holder 6. Cartridge 1 cannot be loaded into 6. Also, due to such inclination or positional deviation, both pick rollers 7a and 7b may
As a result, the timing and pressing force when pressing are different, and even if the inclination or positional deviation of the cartridge 1 with respect to the holder 6 is relatively small, the cartridge 1 cannot be taken into the holder 6.

The present invention has been made in view of the above-mentioned points, and it is an object of the present invention to provide a feeding mechanism in a recording medium cartridge transport device that can reliably take a cartridge into a holder.

[Means to solve the problem]

A feeding mechanism according to a first aspect of the present invention is a recording medium cartridge conveying device including a holder that holds a recording medium cartridge taken in from a cartridge entrance and conveys it to a desired location, in which a recording medium cartridge is inserted into and taken out from the holder. The feeding mechanism includes a first swinging member and a second swinging member that are provided on both sides of the holder to be swingable about respective fulcrums, and a second swinging member that is located outwardly from the cartridge entrance/exit. and the first
and a transfer position provided on each of the second swinging members, which rotates by pressing against both sides of the recording medium cartridge to be taken in and out of the holder as the swinging members swing, thereby feeding the cartridge. a first feed roller member and a second feed roller member that move between a retracted position and a retracted position from which the cartridge is retracted, and are swingably attached to each of the first and second swing members. first and second actuating members, one of which has a right-handed threaded portion and the other has a left-handed threaded portion, and are threadedly engaged with the right-handed threaded portion and the left-handed threaded portion of the first and second actuated members, respectively. a rotating member having a right-hand threaded portion and a left-hand threaded portion, which hold both the actuating members by the screwing; and by rotating the rotating member in one direction, the first and second actuating members By bringing the actuating members close to each other, rotating the first and second swinging members in a direction in which both the feed roller members are in the transfer position, and rotating the rotating members in the other direction, the threaded engagement is achieved. drive means for rotating the first and second swinging members in a direction in which the first and second actuating members are separated from each other and both of the feed roller members are brought to a retreat position. .

Further, the feeding mechanism according to the second aspect of the present invention includes the first
A single actuating member is used in place of the first and second actuating members and the driving rotating member in the feeding mechanism according to the embodiment, and the actuating member is directly rotated by the driving means. That is, the actuating member is swingably attached to one of the first and second swinging members at one end thereof, has a threaded portion at the other end, and has a threaded portion at the other end thereof. It is screwed into the threaded part provided on the other side. The driving means rotates one actuating member in one direction, thereby causing first and second swinging in a direction in which both feed roller members are brought to the transfer position by screwing the actuating member and the other swinging member. By rotating the member and rotating the actuating member in the other direction, the first and second swinging members are rotated in the direction in which both the feed roller members are brought to the retracted position by the aforementioned screw engagement. .

[Effect]

In the feeding mechanism according to the first aspect of the present invention.

When the recording medium cartridge is to be taken into the holder from the transfer source, the rotating member is rotated in one direction by the driving means. In this way, the first and second actuating members, each provided with a right-handed threaded portion and a left-handed threaded portion, move an equal distance in a direction toward each other due to the screw engagement with the rotating member, and accordingly, The first and second swinging members rotate so that each sending member is at the transfer position. At this time, since the first and second swinging members are driven by a common driving means, they are rotated by the same driving force. Further, both feed roller members press against both side surfaces of the cartridge while drawing arcuate loci of the same radius.

Therefore, the cartridge at the transfer source is not tilted or misaligned with respect to the holder, and the first and second cartridges are not tilted or misaligned with respect to the holder.
If the swinging member of is provided so as to be symmetrical with respect to the holder when it is in the standby position, both of the feed roller members press simultaneously against both sides of the cartridge with an equal pressing force. , the cartridge can be transferred to the cartridge inlet/outlet and reliably taken into the holder without being tilted or misaligned with respect to the holder. On the other hand, when the cartridge at the transfer source is tilted or misaligned with respect to the holder, or when the first and second swinging members are in the standby position, it is possible to make the cartridge symmetrical about the holder. If it is not provided, there will be a difference in the timing when both feed roller members press against the side of the cartridge as both swinging members rotate, and both swinging members may be at different angles relative to the cartridge. Stop. However, after both the feeding roller members press the cartridge, the first and second swinging members continue to be given the same rotational driving force by the common driving means, so that at least the cartridge is pressed against the feeding member. At the point just before the cartridge is introduced into the cartridge entrance/exit of the holder (just before the introduction point), the cartridge is rotated so as to have the same inclination angle with respect to the holder, and the pressing force of both feed roller members against the cartridge is also equalized. Become. In this way, the cartridge can be properly adjusted by both feed roller members so that it is not tilted or misaligned with respect to the holder, and can be transferred to the cartridge entrance/exit of the holder, and can be reliably taken into the holder.

Furthermore, in the feeding mechanism according to the second aspect of the present invention, when the recording medium cartridge is to be taken into the holder while being transferred, the actuating member is rotated in one predetermined direction by the driving means. For this reason, the actuating member is swingably attached to one of the swinging members at one end thereof, and is screwed to the other swinging member at the other end, so that both the swinging members can be controlled, respectively. The feed roller member rotates in the direction to the transfer position. Even in this case, after both the feed roller members press the cartridge, the same rotational driving force continues to be applied to both the swinging members by the common driving means, so that at least the cartridge is moved to the cartridge entrance/exit of the holder. When the cartridge reaches the point immediately before introduction, both the swinging members rotate so as to make the same inclination angle with respect to the holder, and the pressing forces of both the feeding members against the cartridge are also made equal. In this way, the cartridge is properly adjusted so that it is not tilted or misaligned with respect to the holder, and is transferred to the cartridge entrance and exit port, and is reliably taken into the holder.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the accompanying drawings.

FIG. 1 shows only a portion of a transport mechanism A according to an embodiment of the present invention, and this embodiment is a transport system [4] of an optical disk library apparatus as shown in FIGS. 4 and 5.
This was carried out in Components labeled with the same reference numerals as in FIGS. 4 and 5 have the same functions as those in the same figures. In FIG. 1, the holder 6 is stopped at a position where its cartridge inlet/outlet 6b directly faces the cartridge inlet/outlet 3b of the drive 3. Further, the leading end portion of the cartridge 1, which has been driven by the drive 3, protrudes from the cartridge entrance/exit port 3b.

In the feed mechanism A, the first swing arm 11 and the second
The swing arm 12 is swingably attached to horizontal frame portions 5a, 5a located on both sides of the holder 6 in the base frame 5 via a support shaft 13.13. The support shaft 13.13 is provided at a position such that a straight line connecting both support shafts 13.13 is perpendicular to the center line 6a of the holder 6 (hereinafter referred to as the holder center line), and
Distance to d1. d2 are equal to each other (d1=d2). In addition, both swing arms 11 and 12 have the same length from each support shaft 13.13 to the tip,
Extending outwardly from the holder 6 toward the drive 3;
Each tip reaches near both sides of the tip portion of the cartridge 1. Pick rollers 7a and 7b are rotatably attached to the tips of each of the swing arms 11 and 12 via shafts 16 and 16, respectively. The pick roller 7a
.

7b is the distance L from each support shaft 13.13.

L2 are attached at positions that are equal to each other (that is, L□=L2), and are opposed to both sides of the distal end portion of the cartridge 1. The pick rollers 7a, 7b are rotated by their respective shafts 16, 16 being driven by rotational driving means (not shown) comprising a motor or the like. In the figure, both swing arms 11.12 are in the standby position, and therefore the pick rollers 7a, 7b are also in the retracted position.

Reference numeral 18 denotes a tension spring that functions as a buffer when the pick rollers 7a and 7b press against the cartridge 1 as the two swing arms 11 and 12 rotate.

In the first and second swing arms 11.12, the distances, L4, from each support shaft 13.13 are the same (
r-z = L4), first and second actuating shafts 19.20 of equal length, extending towards the center line 6a of the holder 6, are attached to each swing arm 11.12. It is connected so as to be able to swing relative to the other end. The first operating shaft 19 has a right-hand male threaded portion 19a in its distal half, and the second operating shaft 20
A left male threaded portion 20a is formed in the tip half of the.

The right male threaded portion 19a of the first operating shaft 19 and the left male threaded portion 20a of the second operating shaft 20 have a stone layer threaded portion (not shown) at one end and a left female threaded portion (not shown) at the other end. It is threadedly engaged with the same cylindrical rotating body 22 formed with the same cylinder (not shown). In this way, the two actuating shafts 19, 20 are connected via the rotating body 22 so as to be perpendicular to the center line 6a of the holder 6. A driven gear 23 is spline-coupled to the outer periphery of the rotating body 22 so as to be slidable in the longitudinal direction of the rotating body 22, that is, in a direction crossing the center line 6a of the holder 6. With such a spline connection, the gear 2
3 rotates the rotating body 22 by rotating itself. Further, the gear 23 is connected to the operating shaft 19.
It meshes with a drive gear 26 that is rotated by a drive shaft 24 that is parallel to 20 .

With this configuration, when the drive shaft 24 is rotated in the H direction by a drive means (not shown) such as a reversible motor, and the driven gear 23 is rotated by the drive gear 26, one rotating body 22
rotates in the J direction. As the rotating body 22 rotates, the rotating body 22 is rotated at each threaded portion 19a, 20a.
By moving along said threaded portion of the first and second actuating shafts 19.20 are moved an equal distance in the direction towards each other. As a result, the first and second swing arms 11 and 12 rotate around the support shafts 13 and 13 to the operating position, and as a result, the pick rollers 7a and 7b move onto both sides of the distal end portion of the cartridge 1. It comes to the transfer position to be pressed. On the other hand, when the pick rollers 7a, 7b are returned to the retreat position after the transfer of the cartridge 1 by the pick rollers 7a, 7b is completed, the drive shaft 24 is
It is rotated in the opposite direction (i.e., the direction).

The rotating body 2 via the driving gear 26 and the driven gear 23
Rotates in two directions. As the rotating body 22 rotates in this manner, the rotating body 2
By moving to the threaded portion of No. 2, the first and second threaded portions
The actuating axes 19,20 of are moved an equal distance away from each other. As a result, the first and second swing arms 11.12 return to the standby position again.

As described above, in this feeding mechanism A, 1) the first and second
The swinging arms 11 and 12 are provided to swing around support shafts 13 and 13 located symmetrically about the holder centerline 6a, and 2) the pick rollers 7a and 7b are
The first and second swing arms 11 and 12 are provided at positions where the distances L□ and L2 from the respective support shafts 13 and 13 are the same, and 3) both the swing arms 11 and 12 are connected to gears. 26.23, the drive 3 is oscillated with the same driving force by a common drive means consisting of the rotating body 22 and the first and second operating shafts 19.20.
Alternatively, the cartridge 1 in the storage slot S is moved along the holder center line 6a and the holder 6 by the pick rollers 7a and 7b.
The cartridge can be transferred to the cartridge inlet/outlet 6b while being appropriately adjusted so that there is no inclination or positional shift.

For example, as shown in FIG. 2, when the drive 3 and the holder 6 are relatively tilted and misaligned, when the cartridge 1 used in the drive 3 is taken into the holder 6, both swing arms 11, 12 As the pick rollers 7a and 7b press against both sides of the cartridge 1 due to the rotation of the cartridge 1, there is a difference in timing.
2 stop at different angles to the cartridge 1, as shown by two-dot chain lines, and in this state also make different angles to the holder center line 6a. Therefore, the pick rollers 7a and 7b
Press with different pressing forces on both sides. however,
The cartridge 1 is transferred by the pick rollers 7a, 7b to a point immediately before the cartridge entrance/exit 6b of the holder 6 (the point immediately before introduction), and is released from the guide by the inner wall surface of the drive 3. ), both swing arms 11 and 12 are rotated to a position where they are at the same angle with respect to the holder center line 6a while being continuously driven by the drive means. Along with this, the pick rollers 7a and 7b press and hold the cartridge 1 and move it to a position that is symmetrical about the holder center line 6a, so that the cartridge 1 is moved so that its center line 1a is aligned with the holder center line. Align it so that it lines up with 6a. At the same time, the pick roller 7a,
The pressing forces of 7b on both sides of the cartridge 1 are made equal. In this manner, the cartridge 1 is automatically adjusted to a state where it is not tilted or misaligned with respect to the holder 6 while being transported by the pick rollers 7a and 7b, and can be accurately inserted into the cartridge entrance/exit port 6b.

Note that the reason why the one rotating body 22 and the driven gear 23 are spline-coupled is that the pick rollers 7a, 7
b to the transfer position, for example, if one pick roller 7a presses the other pick roller 7b, by continuing to rotate the rotating body 22, the oscillator to which the other pick roller 7b is attached is moved. moving arm 1
This is to enable rotation of only the holder 2, and to enable both swing arms 11 and 12 to rotate at the same angle with respect to the holder center line 6a as described above.

Next, the operation of the feeding mechanism A according to the present invention will be explained with reference to FIG.

For example, as shown in the figure, when the drive 3 takes in the used cartridge 1 into the holder 6, the drive shaft 24 is rotated in the H direction, so that the drive gear 26 and the driven gear 23
The rotating body 22 rotates in the J direction via. As a result, the first and second swing arms 11, 12 are rotated to the operating position via the first and second operating shafts 19.20, and as a result, the big rollers 7a, 7b are moved to the transfer position. , press and hold the tip of the cartridge 1. Next, the pick rollers 7a and 7b transfer the pressed and clamped cartridge 1 toward the cartridge entrance/exit 6b of the holder 6 by being rotated by the aforementioned rotation drive means.

At this time, the cartridge 1 is always transported by both pick rollers and its center line 1a is appropriately adjusted to a state where there is no inclination or positional deviation with respect to the center line of the holder 6, so that the cartridge loading/unloading of the holder 6 is prevented. You will definitely be guided during 6b.

When the cartridge 1 is taken into the holder 6 in this manner, the drive shaft 24 is rotated in the mechanical direction, and as the rotating body 22 is rotated in the opposite direction, the first and second swing arms 11, 12 are rotated. is pivoted back to the standby position via the first and second actuating shafts 19,20. Thereafter, the cartridge 1 is taken into a predetermined position within the holder 6 by intermediate feed rollers (not shown) provided on both sides of the intermediate portion of the holder 6. For example, when the cartridge 1 taken into the holder 6 is transported by the holder 6 and fed into the storage slot S of the storage rack 2, after the holder 6 moves to a position directly facing the storage slot S, the cartridge 1 is fed out by the intermediate feeding roller until its leading end protrudes from the cartridge entrance/exit port 6b. Thereafter, as the drive shaft is rotated in the H direction, the first and second swing arms 11, 12 swing to the operating position,
The cartridge 1 is fed into the storage slot S by the big rollers 7a and 7b rotating while holding the tip portion of the cartridge 1. Thereafter, in order to transport the cartridge 1 in another storage slot S to the drive 3, the same operation as described above is performed in the feeding mechanism A when taking the cartridge 1 from the storage slot S into the holder 6. It happens. In particular, when the cartridge 1 is taken into the holder 6 from the storage slot S, the same automatic adjustment by the pick rollers 7a and 7b as described above ensures that the cartridge 1 is taken into the entrance 6b without being tilted or misaligned with respect to the holder 6. It will be done.

3A and 3B show a feeding mechanism A' according to another embodiment of the invention.

This feed mechanism A' swings the first and second swing arms 11 and 12 by one operating shaft 24 provided with a male threaded portion (right male threaded portion or left female threaded portion) 24a on one end side. This mechanism is different from the feeding mechanism A shown in FIG. 1 in that it is configured to do so. That is, the operating shaft 24 is connected to the threaded portion 24a.
At the opposite end, the second swing arm 12 is swingably attached to the second swing arm 12 via a shaft 25 . Further, the operating shaft 24 has a first threaded portion 24a.
It is screwed into a female threaded part (not shown) of a female threaded member 28 fixed in a through hole 11a formed in the swinging arm 11, and the tip part on the side of the male threaded part 24a is connected to the first swinging arm 11. It protrudes from arm 11.

The distance from the fulcrum 13 in the second swing arm 12 to the center of the shaft 25 and the fulcrum 1 in the first swing arm 11
3 to the center of the female threaded portion of the female threaded member 28 are equal to each other.

The tip end portion on the side of the male threaded portion 24a is connected to rotation driving means (not shown) such as a motor. In the illustrated example, when the actuation shaft 24 is rotated in the L direction by the rotation drive means, the first and second swing arms are moved by relative movement between the male threaded portion 24a and the female threaded portion. 1
1 and 12 are rotated to the operating position. Further, when the operating shaft 24 is rotated in the M direction when both swing arms 11, 12 are in the operating position, the first and second swing arms 11, 12 are rotated to the standby position. In this embodiment as well, 17 swinging arms 11.12 are connected to fulcrums 13.13 located symmetrically about the holder center line 6a.
2) The shaft 25 and the female threaded portion are provided at the same distance from each fulcrum 13.13, and 3) Both swing arms 11.12 are provided as operating shafts. 24, the cartridge 1 can be transferred to the cartridge entrance/exit port 6b without being tilted or misaligned with respect to the holder 6.

The present invention is not limited to a transport device for an optical disk library device, but may be applied to a transport device that handles magnetic disk cartridges and other types of recording medium cartridges.

〔Effect of the invention〕

As described above, in the present invention, when a recording medium cartridge is taken into a holder, after both feed roller members move to the transfer position, the first and second swinging members are driven equally by a common drive means. By continuing to be driven to the operating position by force, the recording medium cartridge rotates to a position at an equal angle to the holder, so while being transported by the feed roller member, the recording medium cartridge does not tilt or misalign with respect to the holder. It is automatically adjusted to a state where there is no As a result, the present invention has the excellent effect that the recording medium cartridge can be transferred to the cartridge entrance of the holder without being tilted or misaligned, and that the cartridge can be reliably taken into the holder. Furthermore, since the driving means is shared for both swinging members, the structure is simple.
