BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information recording medium conveying apparatus for recording information on a recording medium and/or reproducing information from a recording medium.

0002

BACKGROUND OF THE INVENTION Information recording and reproducing apparatuses have conventionally been of magnetic type and optical type, and of these, the optical type has been attracting attention in recent years. Devices that record/reproduce information using light beams include optical discs such as CDs and video discs that rotate disc-shaped recording media, magneto-optical discs, optical cards that move card-shaped recording media back and forth, and optical tapes. There are some that use. These devices are used depending on the purpose, and optical cards are attracting particular attention because of their portability. When using an optical card as an information recording medium, various conventional methods have been devised in which a light beam is irradiated onto the optical card, the irradiation position of the light beam is moved in a straight line, and then the position is moved perpendicular to the direction of the linear movement. Systems are known in which relative movement is performed in the direction, ie across the information tracks on the optical card.

As conventional examples of such a system, FIGS.
The one shown in FIG. 14 is known. FIG. 11 shows a perspective view of a first conventional example, in which a mounting table, that is, a card stand 2 movably supported in the X direction along rails 1a and 1b, holds an optical card C inserted from the side in a peripheral area. It is pressed and fixed from above by plate springs 3a and 3b of the card pressing member 3. Feed rollers 4a and 4b for inserting the optical card C into the card stand 2 are rotationally driven by a motor 6 via a drive shaft 5, and transport the optical card C. In order to convey the optical card C to the abutting part 2a of the card stand 2, the card pressing member 3 is provided with notches 3c and 3d.
The feed rollers 4a and 4b are arranged so as to fit into the notches 3c and 3d. The motor 6 and the drive shaft 5 are configured such that a movable core 8 fixed to one end of a member 7 rotatable around a shaft 7a is driven by a spring 9 and a solenoid 10 to move up and down. There is.

FIG. 12 shows a cross-sectional view taken along line PP in FIG. 11, in which (a) shows the state in which the optical card C is inserted into the card stand 2, and (b) shows the state in which the optical card C is inserted from the card stand 2 into the transport system. A state in which certain feed rollers 4a and 4b have come off is shown, and (c) shows a state in which an optical card C is ejected from the card stand 2. The optical card C is conveyed to the abutment part 2a of the card stand 2 by the feed rollers 4a and 4b, and when the optical card C is positioned on the card stand 2, the motor stops, and the feed rollers 4a and 4b are raised by the solenoid 10. Then, the optical card C is removed from the conveyed state. Optical card C positioned on card stand 2
is removed from this conveyance system and performs a linear reciprocating movement together with the card stand 2 to perform recording/reproduction.

After recording/reproducing, the motor 6 rotates in reverse and the solenoid 10 lowers the feed rollers 4a, 4b. Therefore, the optical card C enters the conveyance system and moves forward to the feed rollers 4a, 4b.
It is discharged by b.

FIG. 13 shows a second conventional example, in which an optical card C is mounted on a card stand 12 on parallel shafts 11a and 11b arranged vertically.
Feed rollers 13a, 13b, 13c, 13d to be inserted into
are provided and are arranged facing each other so as to sandwich the optical card C therebetween. In this conventional example, in order to insert the optical card C up to the abutting part 12a of the card stand 12, the length of the card stand 12 in the moving direction is made shorter than the length of the optical card C in the longitudinal direction, and the feed roller 13a to 13d are arranged. FIG. 14(a) is a cross-sectional view taken along the Q-Q line in FIG. 13.
As shown in the figure, the optical card C is sandwiched between the feed rollers 13a to 13d and conveyed to the card stand 12. At this time,
The optical card C is inserted while being urged by the card pressing member 14 so as to be parallel to the pressing surface 15, and the optical card C is inserted into the card stand 12.
The optical card C abuts against the abutting portion 12a and the positioning is completed. When the optical card C is positioned, the feed rollers 13a, 13b, 13c, 13
d move up and down, respectively, and separate the transport system from the optical card C. After that, the process shifts to the recording/playback mode in the same way as the first conventional example.
It is then discharged as shown in (c).

[0007]

However, the mechanisms using the above-mentioned feed rollers have the following common drawbacks. That is, in the first conventional example, since a part of the pressing member 3 that presses the optical card C is cut out, it is not possible to remove warping of the optical card C, and the optical card C becomes large during recording/reproduction. It has the disadvantage of being prone to blur and recording/reproduction errors in the optical head. Further, in the second conventional example, a portion of the optical card C protrudes from the card stand 12, resulting in the same drawback as the first conventional example.

[0008] In any of the conventional examples, in such a feed roller mechanism, the feed roller that conveys the optical card C is close to the card stand on which the optical card C is placed, and cannot perform linear reciprocating motion. Because of this interference, when transferring the optical card C to the card stand, it is necessary to immediately retreat the feed roller and separate it from the card stand after positioning the optical card C. At this time, it is required to stop the rotation of the feed roller accurately and reliably just before retracting, or to prevent the optical card from slipping from the feed roller, but this is extremely difficult and requires the setting accuracy of the optical card. There is a problem that the writing start position varies as a result. Further, at the time of ejection, since the feed roller is brought into contact and reversed after the card stand is moved, the operation is intermittent, making it difficult to shorten the time.

[0009] Conventional mechanisms with the above-mentioned drawbacks are capable of accurately positioning and recording/reproducing in a short transport time for today's optical cards that have miniaturized information recording pits and store a large amount of information on one card. It becomes difficult to do so.

The object of the present invention is to solve the above-mentioned problems,
An object of the present invention is to provide a highly reliable information recording medium transport device that can transport an optical card reliably in a short time, accurately position it on a mounting table.

[0011]

[Means for Solving the Problems] The gist of the present invention for achieving the above-mentioned object is to hold an information recording medium on a mounting table, and to move the mounting table in a straight line in a reciprocating manner with respect to an optical head for recording/reproducing. In an information recording medium transport device that records/reproduces information by making a movement, a feeding means that feeds the information recording medium to the mounting table, and a positioning unit that sets the information recording medium to a reference position of the mounting table. The information recording medium conveying device is characterized in that it has a settling means and an ejecting means for ejecting the information recording medium from the mounting table, and the mounting table is provided with a recording medium ejecting member.

0012

[Operation] The information recording medium transport device having the above-mentioned configuration has the following features:
To quickly and reliably position an information recording medium on a mounting table and discharge the information recording medium from the mounting table.

A sensor 53 is fixed to the settling base 46, and a detection piece 54 attached to the settling damper plate 49 detects a relative positional deviation with the settling damper plate 49.

In front of the driving rollers 24a and 24b, a card stand 55 is movably supported by a mechanism not shown, and this card stand 55 receives an optical card C inserted from the rear.
3, 4, 5, and 6, the card is pressed and fixed from above by card pressing members 55a, and an abutment part 55b for positioning the optical card C is provided at the front. is provided. The pressing member 55a has a longitudinally long shaft 55c sandwiched between it and the upper surface of the card stand 55, and is urged downward on the inside by a spring 56 fixed to the card stand 55. Inside the card stand 55, a drawer plate 57 is held at a position in contact with the back surface of the optical card C so as to be slidable back and forth. A contact portion 57a is formed at the front end of the drawer plate 57 and is bent upward at the center.
The front end of the inserted optical card C comes into contact with it, and an engaging part 57b is formed on a part of the lower surface on the right side of the rear end of the drawer plate 57. It projects downward from the opening 55d.

Further, a discharge arm 58 connected to a part of the guide plate 43a is provided below the drive shaft 23, and the front end of the discharge arm 58 is rotatable via a shaft 59 parallel to the drive shaft 23. L having two rollers 60a
A locking member 60 in the shape of a letter is attached and biased downward by a coil spring 61 wound around the shaft 59. A guide plate 62 having a partially inclined surface is disposed below the lock member 60, and the lock member 60 in contact with the upper surface rotates according to the position of the ejection arm 58, and the engagement portion of the drawer plate 57 57b from the front.

A light shielding plate 63 is fixed to the lower surface of the card stand 55, and a sensor 64 for detecting this light shielding plate 63 is installed on the transport frame 21. Further, when the optical card C is inserted, the card stand 55 is moved to the drive roller 2 by a mechanism (not shown).
4a and 24b are positioned and locked along the conveyance path. Note that 65 is an optical head for performing recording/reproduction on the optical card C.

Next, the operation will be explained. When the optical card C is inserted through the insertion slot 20 and is sandwiched between the driving rollers 24a, 24b and the biasing rollers 30a, 30b as shown in FIG. Biasing roller 30 for the thickness of optical card C
a, 30b are lifted, and the support arm 2 is lifted accordingly.
9a and the lever 32 connected thereto rotate in the direction of arrow A, and the pendulum arm 34 is lifted by the convex portion 34a,
The pendulum gear 37 held by the pendulum arm 34 comes off from the move gear 42a. At the same time, the sensor 35 detects the movement of the tip of the lever 32 and drives the drive motor 27. This driving force is transmitted from the motor gear 28 to the drive rollers 24a and 2 of the drive shaft 23 via the reduction gear 26 and the drive gear 25.
4b, the optical card C is conveyed toward the card table 55 while being sandwiched between the rotating drive rollers 24a, 24b and the urging rollers 30a, 30b.

When the optical card C comes off the driving rollers 24a, 24b and the biasing rollers 30a, 30b, the biasing spring 31a moves around the support shafts 29c, 29d as shown in FIG.
, 31b, the support arms 29a, 29b and the lever 32 rotate in the direction of arrow B, and when they return to the initial state, the pendulum arm 34 rotates around the idler gear shaft 33, and the pendulum gear 37 moves to the move gear 42a. The rotational force of the drive motor 27 is transmitted to the move gear 42a via the connection gear 39. During this series of operations, the rotation direction of the drive motor 27 is the same, and when the optical card C comes off the drive rollers 24a, 24b, the pendulum arm 34 is almost continuously switched to the move gear 42a, and rotated by the move gear 42a. Communicate.

Next, when the side plates 43a, 43b start to move forward, the guide pins 47a, 47b move to the L position.
Since it is regulated by the mold grooves 48a and 48b, the setting base 46 slides directly below along the inclined grooves 43c and 43d of the side plates 43a and 43b, and the inclined grooves 43c and 4
The descent ends when it reaches the lowest end of 3d, and this time it horizontally moves forward along the horizontal portions of the L-shaped grooves 48a and 48b, and the operation from the descent of the settling base 46 to the horizontal movement is performed continuously. . Setting damper plate 49 on setting base 46
moves horizontally from the lowered position and urges the rear part of the optical card C in the longitudinal direction.

On the other hand, as the ejection arm 58 moves forward together with the side plate 43a, the locking member 60 moves along the upper end of the guide plate 62, and is rotated downward by the biasing force of the coil spring 61 on the inclined surface of the guide plate 62. When the pull-out plate 57 is moved, the engagement portion 57b of the drawer plate 57 is disengaged. When the front end of the optical card C inserted into the card stand 55 comes into contact with the abutting part 57a at the front end of the drawer plate 57, the abutting part 57a is urged forward and the optical card C is moved forward together with the drawer plate 57. 57 to card stand 5
5 and abuts against the abutting portion 55b provided at 5.

As shown in FIG. 7, the settling damper plate 49 allows the optical card C to contact the abutting portion 5 via the abutting portion 57a.
It stops in the state where it is set to 5b, and the setting base 4
Only 6 overruns. Therefore, after the optical card C is settled on the card stand 55, the settling base 46 further overruns and applies a biasing force to the settling damper plate 49 to ensure that the optical card C is settled on the card stand 55. At this time, there is a distance difference between the settling base 46 and the settling damper plate 49 corresponding to this overrun, so the detection piece 54 and the sensor 53 are used to confirm the settling of the optical card C. The positioning lock of the stand 55 is released. Note that the optical card C is pressed against the pull-out plate 57 by the spring 56 via the pressing member 55a.

Next, the optical card C positioned and placed on the card stand 55 performs reciprocating linear movement for recording/reproducing. At this time, the settling damper plate 49 is on standby with the transport path of the optical card C blocked. Therefore, even if the operator tries to insert another optical card by mistake, the optical card
hits the settling damper plate 49 and can prevent double insertion of the optical card C.

When the card base 55 comes to the eject position after recording/playback is finished, the light shielding plate 63 overlaps the sensor 64 as shown in FIG. 8, and the drive motor 27 is driven in the opposite direction by the signal from the sensor 64. . The driving force of the drive motor 27 rotates the idle gear 36 via the motor gear 28, reduction gear 26, and connection gear 39, and the pendulum arm 34 rotates in the opposite direction. This causes the pendulum gear 37 to move to the move gear 4.
2a, and the side plate 43a retreats due to the reverse rotation of the move gear 42a. The ejection arm 58 also retreats together with the side plate 43a, and the locking member 60 is urged along the inclined surface of the guide plate 62 and rotates upward to engage with the engaging portion 57b, thereby locking the drawer plate 57 into the optical card C.
The entire card is pulled out from the card stand 55. Since the optical card C is longer than the drawer plate 57, the optical card C is longer than the drive roller 2.
4a, 24b and biasing rollers 30a, 30b, and as a result, the pendulum gear 37 and the moving gear 42a are disengaged, and at this time, the settling base 46 reaches the initial position. Furthermore,
The optical card C is ejected into the insertion slot 20 by rotation of the drive rollers 24a and 24b.

In this way, the settling damper plate 49
Accordingly, the optical card C can be accurately positioned on the card stand 55. Further, the rear end portion of the optical card C positioned on the card stand 55 is energized, thereby increasing the startup speed of the card stand 55 and increasing the recording/reproducing speed. Since the optical card C can be held securely, focus errors and tracking errors caused by vibrations of the optical card C during recording/reproduction are reduced. Further, when ejecting the optical card C, the transport time is short because the operations from pulling out the optical card C from the card table 55 to ejecting it by the driving rollers 24a and 24b are performed continuously.

Next, FIGS. 9 and 10 show another embodiment, and only the parts different from the previous embodiment will be explained here. A rotating ring 42c is rotatably fixed near the circumference of the side surface of the move gear 42a on an axis perpendicular to the surface.
It is configured to be engaged with a groove 71a formed in the side plate 70a, convert the rotational movement of the move gear 42a into a link movement via the groove 71a, and cause the side plate 70a to move linearly. A cam plate 72 is fixed to the left end of the connecting shaft 41, and is connected to the left side plate 70b via a rotating ring 72a and a groove (not shown). Also in this case, the side plate 70a
, 70b are the side plates 43a, 43b of the previous embodiment.
Similarly, linear motion will be performed.

[0031]

As explained above, the information recording medium conveying device according to the present invention can position an optical card at high speed and reliably by the optical card positioning and settling means that operates by engaging with the optical card feeding means. Moreover, when ejecting, the ejecting member pulls out the optical card and performs the ejecting operation continuously, so that ejecting is also fast.
