BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information recording and reproducing apparatus that records and/or reproduces information by moving a mounting table holding an optical card relative to an optical head. [0002] Conventionally, various information recording and reproducing apparatuses for recording information on optical cards and reproducing recorded information have been proposed. For example, JP-A-2-1484
87, as shown in FIG. 5, a card mounting table 31 is provided which moves back and forth via a guide shaft 30 with respect to an optical head for recording and reproducing information, and an optical card 32 is mounted on the card mounting table 31. A loading mechanism is provided. This loading mechanism transports the optical card 32 into the device while being sandwiched between a rubber roller 33 and an opposing roller 34. After loading, these rollers are separated and the optical head records and reproduces information. The content of the information is disclosed. [0003] Furthermore, as shown in FIG. 6, in Japanese Unexamined Patent Publication No. 2-27566, an optical card 36 is conveyed to a shuttle 37 by a rubber roller 35, and the optical card 36 is conveyed to a shuttle 37 by a rubber roller 35.
If the external drive power supply 38 is cut off when taking out the information recording carrier 6, a separate drive power supply 39 is connected to a circuit that supplies power to the conveyance drive source, and the information recording carrier can be removed from the state where it is installed inside the device. The content that can be retrieved is disclosed. [0004]

[Problems to be Solved by the Invention] However, with the above conventional example, if the power supply to the device is stopped due to a power outage or some kind of failure, or if normal operation cannot be performed, the internal It becomes difficult to take out the stored optical card. In other words, in the conventional example having rollers that are separated from each other, the rollers are driven via electromagnetic components such as solenoids, so that it is no longer possible to hold the optical card. Therefore, there is a problem in that extremely complicated work is required, such as disassembling the device to take out the optical card or pinching the optical card with a tool to take it out. [0005] In addition, in the conventional example provided with an emergency drive power source, the shuttle moves to the vicinity of the insertion port, but the roller does not move away, so the ejection knob is connected to the roller with a gear etc. etc. can be discharged by manually rotating it. However, in this device, if the optical card mounting table goes out of control due to some kind of failure, the optical card will collide with the roller, causing damage to both. Furthermore, since the roller is located outside the range of movement of the optical edge during information recording and reproduction, there is a problem in that the overall length of the apparatus becomes longer, leading to an increase in the size of the apparatus. [o o 06] The present invention is proposed to solve the above-mentioned problems, and even if the power supply from the outside is stopped due to a power outage or failure, the optical card can be easily taken out of the device, thereby preventing abnormalities from occurring. The object of the present invention is to provide an information recording/reproducing device that does not cause damage to optical cards or the like and does not cause the device to become larger. [0007]

[Means for Solving the Problems] In order to achieve the above-mentioned objects, the present invention includes: a conveyance roller for conveying an optical card into an apparatus; a separation roller disposed opposite to the conveyance roller and capable of being separated from the conveyance roller; In an information recording and reproducing apparatus that includes a mounting table that holds a transported optical card and a driving means that moves the mounting table with respect to an optical head that records and/or reproduces information, the separating roller is manually operated. and a rotation mechanism for manually rotating the conveyance roller, and the information recording device is provided with a lever that enables the conveyance roller to be manually rotated, and the optical card held on the mounting base can be manually taken out of the device via the conveyance roller. This is a playback device. [0008]

[Operation] By operating the lever connected to the separation roller in this way, the optical card can be easily taken out of the device via the rotation mechanism while the optical card is held between the transport roller and the separation roller. I can do it. [0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings. FIG. 1 shows a first embodiment of the present invention, and is a perspective view of the main parts. A front panel 1 on the front of the device is provided with a card insertion slot 3 for inserting and removing an optical card 2.
A photosensor 4 is provided near the card insertion slot 3 to detect whether or not a card is inserted. The photo sensor 4
The optical card 2 that has passed through the card insertion slot 3 is near the
In order to restrict the intrusion into the inside of the device, a shutter 5 is provided which is opened and closed by a shutter driving means (not shown). [00101 Deeper than the shutter 5, a conveying roller 7 held by a shaft 6 is provided so as to convey the optical card 2 while contacting both ends of the optical card 2. The transport roller 7 includes a worm gear 10 fixed to the power shaft of a motor 9 disposed below so as not to contact the optical card 2 placed on the shuttle 8, and a worm wheel 11 meshed with the worm gear 10. The shaft 6 rotates by receiving the rotational motion of the shaft 6. [00111 A groove 12 is formed at the end of the worm wheel 11 in the direction of the card insertion slot 3 so that it can be rotated by hand 4 by engaging a driver or the like from outside the device. [0012] A separating roller 13 configured to be able to perform a dance is provided above the conveying roller 7, and
The optical card 2 is held between the two rollers as they come close to each other.
They are kept separate except during transportation. Note that the separation roller 13 is rotatably held on a shaft 14. This shaft 14 is held by a rotating member 15, which will be described later. [00131 Deeper inside the device than both rollers, there is provided a rotating member 15 rotatably supported via a central shaft 15a disposed parallel to the shaft 6.14. A lever 16 is connected to one side of the rotating member 15 so that the rotating member 15 can be manually operated from outside the device. The rotating member 15 also has a pull shaft 1 parallel to the central axis 15a.
7 is provided, and the rotating member 15 is driven by a right solenoid 18 and a left solenoid 19 arranged on both sides of the pulling shaft 17. When both solenoids 18 and 19 are attracted (ON), the separation roller 13 approaches the transport roller 7, and the optical card 2 is held between the transport roller 7 and the separation roller 13, and when both solenoids are OFF, The separation roller 13 is separated from the conveyance roller 7 by a return spring 20 provided on the rotating member 15 . [0014] Deeper inside the device than the conveyance roller 7,
A shuttle 8 on which the optical card 2 is placed is provided, and is movable in the Z direction via a guide rail (not shown). The shuttle 8 has a pressing plate 21 and a pushing plate 22, and is adapted to hold the optical card 2 between them. FIG. 2 is a side view of the vicinity of the shuttle 8, showing the shuttle 8 in a loading position. The push-up plate 22 is biased toward the presser plate 21 by a push-up spring 29, and a base 31 is provided with an elastic member 30 below the shuttle 8 to restrict movement of the shuttle 8 in the Z direction. . FIG. 3 is a partial perspective view of another embodiment of the presser plate and the push-up plate, but the basic configuration is shown in FIG.
Since this is similar to the above, further explanation will be given based on this. Although the press plate 23 is fixed, the push-up plate 24 is urged toward the press plate 23 by a spring (not shown). Furthermore, the push-up plate 24 is made of an elastic member, and when the optical card 2 is inserted between them, the protruding pieces 24a of the push-up plate 24 can be provided on the outside of each of the separation rollers 13. certain flange 25
is performed while pushing down and bending. The holding onto the shuttle 8 is completed by abutting against an abutting portion (not shown) provided at the end in the insertion direction. [0015] An optical head 26 for recording and reproducing information on the optical card 2 is disposed above the shuttle 8, and irradiates a light beam onto the information track of the optical card 2 under focus control and tracking control. It is supposed to be done. [0016] Next, the operation of this embodiment configured as described above will be explained. In the initial state of the apparatus before the optical card 2 is inserted into the apparatus, the shuttle 8 is in the loading position shown in FIG. 2 and is fixed by a locking means (not shown). When the optical card 2 is inserted into the card insertion slot 3, the photosensor 4 detects it, and the shutter 5 opens to allow the optical card 2 to be inserted into the device. [0017] Then, the motor 9 starts rotating, and the transport roller 7 rotates to transport the optical card 2 into the apparatus via the worm gear 10, worm wheel 11, and shaft 6. At the same time, the right solenoid 18 and the left solenoid 19 are driven and attracted, thereby moving the pull shaft 17 in the direction of the card insertion slot 3. As a result, the rotating member 15 rotates around the central axis 15a.
, and lowers the separation roller 13 so as to approach the conveyance roller 7. At the same time, the flange 25 is lowered, the push-up plate 22 of the shuttle 8 is lowered, the optical card 2 can be inserted, and the optical card 2 held between the transport roller 7 and the separation roller 13 is inserted into the shuttle 8. When the optical card 2 reaches a predetermined position on the shuttle 8, the motor 9
stops rotating and conveyance of the optical card 2 stops. at the same time,
Since the right solenoid 18 and the left solenoid 19 also stop driving, the rotating member 15 is rotated by the spring 20, and the separating roller 13 and flange 25 are also pulled up. At this time, the shutter 5 is closed and additional insertion of the optical card 2 is prevented. [00181] Next, the shuttle 8 is reciprocated in the Z direction by a drive motor (not shown), while the optical head 26 irradiates a light beam onto the information recording surface of the optical card 2 to record and reproduce information. During recording and reproduction, the separation roller 13 and flange 25 are retracted upward, and the conveyance roller 7 is arranged so as not to obstruct the movement of the shuttle 8, so even if the shuttle 8 moves back and forth from the loading position. , the shuttle 8 and the optical card 2 are connected to the separation roller 1
3. Collision with the flange 25, conveyance roller 7, etc. does not occur. In this respect, compared to the conventional configuration in which the loading position of the shaft 8 is provided outside the range of reciprocating motion during information recording and reproduction, the size in the shuttle movement direction is shortened, making it possible to realize a compact apparatus. In this way,
When the recording and reproduction of information is completed, the shuttle 8 moves to the loading position and is again fixed by a locking means (not shown). [0019] Next, when an ejection signal is outputted by an eject button or the like, the motor 9 is driven and the transport roller 7 is rotated so that the optical card 2 is ejected from the apparatus. At the same time, the left and right solenoids 18 and 19 are driven to rotate the rotary member 15 and lower the spacing roller 13 and flange 25. Further, the shutter 5 is opened, and the optical card 2 held between the separation roller 13 and the conveyance roller 7 is conveyed out of the apparatus. After a predetermined period of time has elapsed, the motor 9 and both solenoids 18, 19 stop driving. At this time, since the optical card 2 protrudes outside from the card insertion slot 3, when the user pulls it out, the photosensor 4 stops sensing and the shutter 5 also closes, completing the series of operations of the device. [00201 If the shuttle 8 runs out of control during reciprocating motion due to a power outage, device failure, etc. during recording and reproduction, the shuttle 8 hits the elastic material 30 and stops while the impact is absorbed. In this case, since the separating roller 13 and flange 25 are retracted upward, the shuttle 8 and the optical card 2 will not collide with them and will not be damaged. [00211] Next, a description will be given of the operation of removing the optical card 2 from the apparatus when the external power supply to the apparatus is stopped due to a power outage or the like, or when a failure of the apparatus occurs. First of all,
The front panel 1 is opened by a front panel opening/closing mechanism (not shown). Next, a knob (not shown) connected to the power shaft of a drive motor (not shown) is turned to fix the shuttle 8 at the loading position. Next, as shown in FIG. 1, the lever 16 is pushed down in the direction of the arrow A to rotate the rotating member 15, bringing the separating roller 13 close to the conveying roller 7 and sandwiching the optical card 2. and,
While pushing down the lever 16, use a screwdriver or the like to rotate it in the direction B through the groove 12 of the worm gear 10. When the worm gear 10 is rotated several times in this manner, the optical card 2 held between the conveyance roller 7 and the separation roller 13 comes out from between both rollers 7.13. At this point, the lever 16 that had been pressed down is released, the open front panel 1 is closed, and the take-out operation is completed. [0022] In this way, even if the optical card is left inside the device due to power outage, device failure, etc., the front panel 1
To open, after locking the shuttle 8 in the loading position, push down the lever 16 and hold the optical card 2 between the separation roller 13 and the transport roller 7, then press the lever 16.
The optical card 2 can be taken out by rotating the worm gear 10 using a drive bar while holding the worm gear 10. In this case, even if the shuttle 8 goes out of control, the shuttle 8,
The optical card 2 is designed not to cause damage. Also,
Since the separation roller 13 and flange 25 are retracted upward during recording and reproduction, a loading position can be provided within the reciprocating range of the shuttle 8, and the apparatus can be made more compact. [0023] In the above embodiment, the lever 16 is not operated by hand, but as shown in FIG. Alternatively, the lever 16 may be operated by rotating it in the direction of arrow C above the lever 16. That is, when the lock plate 28 is rotated to the solid line position, the lever 16 is lowered, and when the lock plate 28 is rotated to the broken line position, the lever 16 is pulled up. [0024]

Effects of the Invention As explained above, the present invention prevents power outages by manually moving the separation roller disposed opposite to the conveyance roller for optical card conveyance via a lever.
Even if an optical card is left behind in the device due to equipment failure,
Can be taken out easily. In addition, the apparatus of this embodiment can prevent damage to optical cards and the like due to runaway of the card mounting table, as well as an increase in the size of the apparatus configuration.
