The present invention relates to an information recording / reproducing apparatus having

2. Description of the Related Art This type of information recording / reproducing apparatus has conventionally been classified into a magnetic system and an optical system. In recent years, the optical system has attracted attention. Examples of devices for recording / reproducing information using a light beam include a CD, a laser disk for rotating a disk-shaped recording medium, an optical card for reciprocating a card-shaped recording medium, and an apparatus using an optical tape. Can be These devices are properly used depending on the purpose of use, and among them, optical cards have been particularly attracting attention because of their excellent storage and portability.

In this optical card, tracks are formed at intervals of several microns, and between the tracks, spots of several microns are formed by a light beam to record information and to form the formed spots. Is irradiated with a light beam and the reflected light is detected to reproduce information. As an apparatus for this, the mounting table on which the optical card is mounted and the optical head are driven in directions orthogonal to each other,
An information recording / reproducing apparatus that performs recording / reproducing by irradiating an optical card with an optical beam while following the track in parallel has already been proposed.

In such an information recording / reproducing apparatus, since information is recorded / reproduced using a light beam, the surface of the optical card on the light beam incident side needs to be clean.
There has been proposed an information recording / reproducing apparatus in which a cleaner for cleaning the surface of an optical card is incorporated inside the apparatus. FIG.
Shows an example of an information recording / reproducing apparatus in which a cleaner is built in the apparatus. Here, the cleaner is provided inside the apparatus near the insertion slot 30. In the figure, reference numeral 32 denotes a detecting means of the optical card C, 33 denotes a cleaning roller having a cleaning member, and 34 denotes a transport roller. The cleaner is for cleaning the surface of the optical card C on the recording surface side. As a specific configuration, a cleaning roller 33 is used here. This has an ultra-fine fiber cloth on its surface, and the cleaning roller 33 and the transport roller 34 are arranged at a predetermined interval. The cleaning roller 33 includes an urging spring 39.
, And is urged toward the transport roller.

Reference numerals 35 and 36 denote transport roller pairs, 3
Reference numeral 7 denotes a mounting table, and 38 denotes a notch roller provided corresponding to the mounting table.
The transmission 36 (not shown) between the gear train or the pulley and the timing belt is rotated by a motor (not shown) as the same drive source so that the roller 36 and the notch roller 38 rotate.
And are linked.

When the optical card C is inserted through the insertion slot 30, the leading end of the optical card C is detected by the detecting means 32.
The motor is driven, and the driving force is transmitted via the transmission system, and rotates the transport roller 34, the transport rollers 35 and 36, and the notch roller 38, respectively. When the leading end of the optical card C reaches the portion of the cleaner, the rotation of the cleaning roller is stopped by a ratchet (not shown). Thus, the optical card C is transported by the transport roller 34 rotated by the motor while the surface of the optical card C is cleaned by the cleaning roller.
And the cleaning roller 33, and then sent to the inside of the apparatus. Next, the sheet is further sent to the inside of the apparatus by a pair of conveying rollers 35 and 36, and finally, by a notch roller 38 to a predetermined position on the mounting table. Conveyed.

In this way, the optical card C is
Is mounted, the mounting table 37 is moved in a direction perpendicular to the paper surface, and the optical head 40 is relatively moved in a direction orthogonal to the moving direction of the mounting table 37 to record or reproduce information. It is.

[0008]

In the above-mentioned conventional example, the detecting means is provided just inside the insertion slot 30, and the driving of the transport system is started based on the output signal. Therefore, at the beginning of the conveyance, the optical card C is
It is necessary to convey only with the conveyance roller 34. The surface of the optical card is cleaned while sliding on the cleaning member whose rotation has been stopped. At this time, frictional resistance occurs between the cleaning member and the surface of the optical card C. The coefficient of friction between the ultrafine fiber cloth used as the cleaning member and the surface of the optical card C is about 0.2 when the cleaning member is new and clean, but when the cleaning member is dirty, , About 0.4. At this time, the transport resistance by the cleaner is 0.4 W, where W is the urging spring force.

On the other hand, as a material of the transport roller, for example, polyurethane rubber is used. The coefficient of friction between the polyurethane rubber and the optical card is about 0.9 when the surface of the optical card is clean, but is 1/3 when a fingerprint or the like is attached to the surface of the optical card in contact with the drive roller. It drops to about 0.3. At this time, the card conveying force of the driving roller is 0.3 W.

Therefore, if an optical card with a fingerprint is inserted when the cleaning member becomes dirty, the frictional resistance of the cleaner by the cleaner becomes larger than the card conveying force of the conveying roller 34, and the optical card cannot be conveyed. There was a problem.

Although this problem can be solved by providing a pair of conveying rollers having a conveying force between the detecting means 32 and the cleaner, it requires a new pair of conveying rollers and a transmitting means. This leads to an increase in the complexity, size and cost of the apparatus, which is not preferable.

In the conventional example, when the leading edge of the optical card enters the gap between the cleaning roller 33 and the transport roller 34, the edge of the optical card damages the surface of the transport roller 34, and as a result, the optical card is rotated by the motor. There is also a problem that the conveying force of the conveying roller 34 is reduced.
In addition, since the transport roller 34 of the cleaner is connected to and driven by a transmission such as a gear train, a pulley and a belt with respect to a motor serving as a driving source, the number of parts constituting the apparatus increases. , Equipment complexity, assembly man-hours up,
It is a factor of cost increase.

Further, in the conventional example, when the optical card is loaded,
The edge of the leading end of the optical card in the insertion direction is a pair of transport rollers 35,
Since it is pressed against the circular surfaces of the roller 36 and the notch roller 38, the circumference of each roller is shaved by the edge, and there is also a problem that the durability is reduced. If there is an optical card detecting means closer to the insertion port than the pair of rollers for transporting the optical card, the drive source of the transport roller is started based on this output signal, so that after the rotation of the transport roller is started, In addition, since the time required to start the transport of the optical card is not constant, it is necessary to rotate the motor as a drive source more than necessary, so that the loading time of the optical card becomes longer and extra power is consumed. was there.

The present invention has been made based on the above circumstances, and an object thereof is to provide an information recording / reproducing apparatus incorporating a cleaner for cleaning the surface of an information recording medium such as an optical card with a simple configuration. Another object of the present invention is to provide an information recording / reproducing apparatus having good operability, capable of securely loading an optical card, and having card loading means having excellent durability.

[0015]

In order to achieve this object, the present invention provides a cleaner for cleaning the surface of an information recording medium inserted into an apparatus through an insertion port, and a method for cleaning the inserted information recording medium. It has a transport means for transporting, and a mounting table for mounting and positioning the information recording medium accommodated inside the apparatus, and mounting the information recording medium on the mounting table and moving the mounting table. In an information recording / reproducing apparatus for performing recording and / or reproduction, the transporting means is an information recording medium which is sequentially arranged along a transport direction of the information recording medium on a side opposite to the insertion port with the cleaner interposed therebetween. At least two pairs of transport rollers for transporting the recording medium, and means for detecting the information recording medium on the side of the transport roller pair facing the cleaner, which is disposed at a position furthest away from the cleaner. The distance from the outer surface of the insertion opening to the detection means is shorter than the length of the information recording medium in the insertion direction, and at least one roller of each transport roller pair is a notch roller having a notch formed on its peripheral surface. hand,
The transport unit is configured such that, when the information recording medium is inserted, the rollers of all the transport roller pairs form an interval equal to or greater than the thickness of the information recording medium, and the detecting unit detects the inserted information recording medium. The information recording medium is controlled so as to be loaded based on an output signal when a side on the insertion direction side is detected.

Accordingly, when the operator inserts and pushes the optical card from the insertion slot by hand, the optical card sequentially has an interval larger than the thickness of the information recording medium while the surface of the optical card is cleaned by the cleaner. After passing through a plurality of pairs of transport rollers, the rollers reach a detection unit. Thereafter, the side of the optical card in the insertion direction is detected by the detecting means, and the drive signal of the transporting means is driven by the detection signal as a trigger to load the optical card.

In addition, according to the present invention, the optical card is inserted between the pair of transport rollers, and then the transport rollers are rotated. Therefore, there is no need to transport the optical card by the cleaner.
Parts for driving the cleaner are no longer required, simplifying,
The size and cost can be reduced. Also, since the optical card is not conveyed at the cleaner, even if the edge of the optical card insert damages the surface of the roller facing the cleaning member, the card loading is hardly affected. Absent. Further, in the present invention, the optical card is sandwiched between a plurality of pairs of transport rollers and then the driving unit of the transport unit is driven, so that the optical card can be transported reliably against the sliding resistance of the cleaning member.

According to an embodiment of the present invention, at least one of a plurality of pairs of transport rollers is a notch roller having a notch in the circumference, so that a transport roller is inserted when an optical card is inserted. Since the distance between the rollers of the roller pair can be set to be equal to or greater than the thickness of the information recording medium, when inserting the optical card by hand, it is possible to insert the optical card with a small force without impairing operability, and at the time of loading, Since the leading edge does not cut the circumferential surfaces of the transport roller pair and the notch roller, durability and reliability are improved.

Further, in this embodiment, the information recording / reproducing apparatus is arranged such that, when the information recording medium is ejected from the mounting table, the side of the information recording medium, which is ejected by the information recording medium detecting means, is opposite to the ejection direction of the information recording medium. After the detection, the notch roller is stopped at a position where the distance between the rollers of all the conveying roller pairs is equal to or greater than the thickness of the information recording medium. Never touch. Therefore, the information recording medium can be easily pulled out of the device.

Further, according to the present invention, the cleaner for cleaning the surface of the information recording medium inserted into the apparatus through the insertion port, the transport means for transporting the inserted information recording medium, and the cleaning device are housed inside the apparatus. A mounting table for mounting and positioning an information recording medium, and for recording and / or reproducing information while mounting the information recording medium on the mounting table and moving the mounting table. The cleaner is configured so as not to perform a transport operation on the information recording medium when loading and discharging the information recording medium onto and from the mounting table, and the transport unit is disposed on a side opposite to the insertion port with the cleaner interposed therebetween. , A first transport roller pair disposed adjacent to the cleaner, a second transport roller pair disposed at a position corresponding to the mounting table, and a second transport roller pair disposed on a side facing the cleaner. Is And a detecting means of the information recording medium, the distance to the detector from the outer surface of the insertion opening,
The length of the information recording medium is shorter than the length in the insertion direction, and at least one roller of each transport roller pair is a notch roller having a notch formed on a peripheral surface thereof, and the transporting means includes: At the time of insertion, the rollers of the first and second transport roller pairs form an interval equal to or greater than the thickness of the information recording medium, and the detecting means detects the side of the inserted information recording medium in the insertion direction. To perform the loading operation of the information recording medium based on the output signal when the
The information recording medium is conveyed to the mounting table by the first conveyance roller pair and the second conveyance roller pair while the information recording medium is positioned at a predetermined position, and then the second conveyance roller pair is slipped. The second pair of conveying rollers to reduce the conveying force of the first pair of conveying rollers, and the conveying force of the first pair of conveying rollers and the conveying force of the second pair of conveying rollers. Is set to be larger than the frictional resistance of the cleaner.

Therefore, when the information recording medium is conveyed into the apparatus and the information recording medium is simultaneously held by the cleaner, the information recording medium is always transported by the first conveying roller pair and the second conveying roller pair. The information recording medium is conveyed while being clamped. Since the sum of the conveying force of the first conveying roller pair and the conveying force of the second conveying roller pair is larger than the frictional resistance of the cleaner, the information recording medium is conveyed into the apparatus. be able to.

Further, since the two pairs of conveying rollers cooperate to convey against the frictional resistance of the cleaner, the conveying force of each pair of conveying rollers can be reduced, and the durability of the conveying rollers is improved. I do.

In this case, the first conveying roller pair and the second conveying roller pair
The information recording medium is transported to the mounting table by the transport roller pair, and after the information recording medium is positioned at a predetermined position, the second transport roller pair is slipped to perform positioning, and the second transport roller pair is positioned. Is smaller than the conveying force of the first conveying roller pair, the information recording medium is positioned at a predetermined position on the mounting table, and then the second conveying roller pair slips on the information recording medium. The required force can be reduced. For this reason, it is possible to reduce the size of the motor as the drive source, reduce power consumption, and reduce the size of the device.

Further, since the conveying force of the second conveying roller pair is small, the clamping force of the second conveying roller pair on the information recording medium can be reduced, and the load on the conveying roller can be reduced.
, The durability of the transport roller can be improved.

In the case where the first conveying roller pair and the second conveying roller pair have the same conveying force, the second conveying roller pair always slips when the information recording medium is loaded.
Although the durability was lower than that of the first conveying roller pair, in the present invention, the conveying force of the second conveying roller pair is made weaker than the conveying force of the first conveying roller pair. Can be made closer to the durability of the first transport roller, and the loading durability of the information recording medium as an apparatus is improved.

Reference numeral 14 denotes an optical head,
It is configured to be able to reciprocate in the BB direction.

(First Embodiment) Next, FIGS.
The operation of loading the optical card according to the first embodiment of the present invention will be described with reference to FIG. In FIG. 1, the optical card 1 is inserted in the direction of arrow C. The optical card 1 is inserted into the information recording / reproducing device 2 from the insertion slot 3, and then,
The leading end of the optical card 1 reaches the cleaning roller 4 and the receiving roller 5 which are arranged opposite to each other with a predetermined gap, and the cleaning roller 4 urged in the direction A by the urging spring 6 is moved.
The urging spring 6 is slightly pushed up in the direction A 'opposite to the urging direction. As a result, the cleaning member on the outer circumference of the cleaning roller 4 is pressed against the surface of the optical card 1 on the recording surface side 1c. Assuming that the urging force of the urging spring 6 at this time is W and the friction coefficient between the cleaning member and the recording side surface of the optical card is μ1, the frictional resistance is μ1 ×
W. The coefficient of friction μ1 during cleaning when using a microfiber cloth as the cleaning member is about 0.2 when the cleaning member is clean, and is about 0.4 when the cleaning member is contaminated. Therefore, the frictional resistance due to the cleaner is expressed by the following equation.

The frictional force by the cleaner = 0.2 × W to 0.4 × W (1) Specifically, since W is about 200 g, the insertion resistance is about 40 to about 80 g. Here, since the receiving roller 5 is not connected to the motor as the driving source, it does not transport the optical card 1.

The position of the first notch roller 7 and the second notch roller 11 is controlled by generally known position detecting means combining a notch disk and a photodetector. When the optical card is inserted, as shown in FIG. 1, the distance between the first notch roller pairs 7 and 8 and the second notch roller pairs 11 and 12 is equal to or greater than the thickness of the optical card 1. Stopped at a certain position.

Therefore, when the optical card 1 is further inserted against the frictional resistance of the cleaner 10, the leading end of the optical card 1 in the insertion direction firstly cuts the notch roller 7 as the first conveying roller pair. After passing through the notch portion and the gap of the first roller 8 which is equal to or more than the thickness of the optical card 1, the notch portion of the notch roller 11, which is the second conveying roller pair, and the optical card 1 of the second roller 12 And reaches the detecting means 13 through a gap not less than the thickness of. The state is shown in FIG.

At this time, the edge of the leading end in the insertion direction of the optical card 1 passes through the first notch roller 7 and the second notch roller 11 without being in contact with the respective circumferential portions. At the time of rotation, the circumferential portion for transporting the optical card 1 is not damaged. Further, since the distance from the outer surface of the insertion slot 3 to the detection means 13 of the information recording medium is shorter than the length of the optical card 1 in the insertion direction, when the optical card 1 is inserted, the optical card 1 becomes It is detected by the detecting means 13.

Next, based on the detection signal of the optical card 1 from the detecting means 13, the first notch roller 7 and the second notch roller 11 rotate in the direction of arrow D in FIG. A motor (not shown) is rotated to perform the operation. Then, as shown in FIG. 3, the optical card 1 is moved to the first conveying roller pair by the first conveying roller pair.
The sheet is conveyed into the apparatus by the circumferential portion of the notch roller 7 and the first roller 8 and the circumferential portion of the second notch roller 11 and the second roller 12 of the second conveying roller pair. Here, the material of the first notch roller 7 and the second notch roller 11 is polyurethane, and the frictional resistance when a fingerprint adheres to the surface 1a on the recording surface side of the optical card 1 is about 0.3. Assuming that the holding force of the first conveying roller pair 7 and 8 and the second conveying roller pair 11 and 12 for each optical card 1 is W as in the case of the cleaner, the first conveying roller pair 7 and 8 is provided. And the transport force of the second transport roller pair 11 and 12 is 0.3 × W, respectively. Accordingly, the conveying force by the two pairs of conveying rollers is as follows.

The conveying force of the two pairs of conveying rollers = 2 × 0.3 × W = 0.6 × W (2) Comparing this conveying force with the equation (1) for the frictional resistance of the cleaner 10, Since the frictional force of the maximum is 0.4 × W and the conveyance force of the two pairs of conveyance rollers is 0.6 × W, the conveyance force of the two pairs of conveyance rollers> frictional resistance of the cleaner, Even in the worst case where a cleaning member is dirty and a slippery optical card with a fingerprint attached is inserted, the optical card 1 can be reliably placed on the mounting table 9 because the card transport force exceeds the frictional resistance of the cleaner. Can be transported.

When the rotation of the motor is further continued, the side opposite to the insertion direction of the optical card 1 sequentially passes through the cleaner 10 and the first pair of conveying rollers 7 and 8, and finally the second side. The sheet is conveyed by a pair of conveying rollers 11 and 12. When the leading end of the optical card 1 in the insertion direction contacts the stopper 9a of the mounting table 9, the circumference of the second notch roller 11 and the surface 1c of the optical card 1 slip. As shown in FIG. 4, at a position where the notch of the second notch roller 11 forms an interval with the second roller 12, the rotation of a motor (not shown) is stopped and the mounting table of the optical card 1 is stopped. Then, the loading operation to the No. 9 is completed. Here, as shown in FIG.
Since the optical card 1 and the optical card 1 are not in contact with each other, the mounting table 9 can freely move in a direction perpendicular to the paper surface.

When the optical card 1 is ejected out of the apparatus, the optical card 1 shown in FIG.
When the mounting table 9 is returned to the position where the optical card 1 is inserted and the motor is rotated in the opposite direction of the loading, the first notch roller 7 and the second notch roller 11 rotate in the direction of arrow E. First, the optical card 1 is conveyed in the discharge direction on the circumferential surface of the second notch roller 11, and is then sandwiched between the first notch roller pairs 7 and 8, so that the first notch It is conveyed on the circumferential surface of the roller 7. Then, the leading end of the optical card 1 in the ejection direction passes through the cleaner 10 and is exposed to the outside of the apparatus from the insertion slot 3.

Further, the transport of the optical card 1 is advanced, and after the detecting means 13 detects the side opposite to the discharging direction of the discharging optical card 1, the first roller pair 7, 8 and the second roller pair are detected. At a position where the distance between the rollers of the roller pairs 11 and 12 is equal to or greater than the thickness of the optical card 1, the motor is stopped and the discharging operation is stopped. In this state, the circumference of the first notch roller 7 and the circumference of the second notch roller 11 are not in contact with the surface of the optical card 1, so that the optical card 1 can be easily pulled out. .

In this embodiment, an information recording / reproducing apparatus of a type in which an optical head reciprocates in a direction parallel to an optical card insertion direction and a mounting table reciprocates in a direction orthogonal to the optical card insertion direction will be described. However, the same effect can be obtained in an information recording / reproducing apparatus of a type in which the mounting table reciprocates in a direction parallel to the insertion direction of the optical card and the optical head reciprocates in a direction perpendicular to the insertion direction of the card.

Further, in the embodiment of the present invention, an optical card has been described as an example of the information recording medium, but any card-shaped recording medium may be used, such as a magnetic card, a magnetic / optical hybrid card, an IC card, or the like. Of course, an information recording medium such as a card or a hybrid card of an IC and an optical card may be used.

(Second Embodiment) Next, a second embodiment of the present invention will be described.
An embodiment will be described. In this configuration, the cleaning roller 4 and the surface 1a on the recording surface side of the optical card 1 are provided.
Assuming that the frictional resistance between the first pair of conveying rollers is Rc, the conveying force of the optical card in the first conveying roller pair 7 and 8 is F1, and the card conveying force of the second conveying roller pair 11 and 12 is F2, the following three conditions are satisfied. Is determined to meet.

Rc <F1 + F2 and F1> F2 (1) Since other points are the same as those of the first embodiment,
Description is omitted.

The loading operation of the optical card here is almost the same as that of the first embodiment, but here, in particular, the optical card 1 further resists the frictional resistance with the cleaning member.
Is inserted, the leading end of the optical card 1 in the insertion direction first passes through the gap between the notch of the notch roller 7 as the first transport roller pair and the first roller 8, and then the second roller
Then, it passes through the gap between the notch portion of the notch roller 11, which is the pair of conveying rollers, and the second roller 12, and reaches the detecting means 13.

As in the above-described embodiment, the distance from the outer surface of the insertion slot 3 to the information recording medium detecting means 13 is shorter than the length of the optical card 1 in the insertion direction. When the optical card 1 is inserted, the optical card 1 is detected by the detecting means 13. Next, based on the detection signal of the optical card 1 from the detection means 13, the motor () is rotated so that the first notch roller 7 and the second notch roller 11 rotate in the direction of arrow D in FIG. (Not shown). Then, as shown in FIG. 3, the optical card 1 is moved by the circumferential portion of the first notch roller 7 of the first conveying roller pair and the first roller 8 and by the second roller of the second conveying roller pair. It is simultaneously pinched by the circumference of the notch roller 11 and the second roller 12.

At this time, the sum of the frictional resistance of the cleaner 10, the conveying force of the first conveying roller pair 7, 8 and the conveying force of the second conveying roller pair 11, 12 is expressed by the following equation (1). For this reason, the optical card 1 can be conveyed against the frictional resistance of the cleaner 10. At this time, since the optical card 1 is transported by two pairs of transport rollers, the transport force per transport roller pair can be set lower than when transported by only one transport roller pair. Therefore, the holding force of the pair of transport rollers on the optical card 1 can be reduced, and the load on the transport rollers can be reduced, so that the durability of the transport rollers can be improved.

When the first conveying roller pair 7, 8 and the second conveying roller pair 11, 12 cooperate to convey the optical card 1, the side opposite to the insertion direction of the optical card 1 becomes Cleaner 1
As a result, the optical card 1 is transported by the first transport roller pairs 7 and 8 and the second transport roller pairs 11 and 12. After this, optical card 1 and cleaner 1
Since the frictional resistance of 0 disappears and the transport resistance decreases,
The transport force required to transport the optical card 1 is reduced, and transport can be performed with a very small transport force.

Next, the side opposite to the transport direction of the optical card 1 is separated from the first transport roller pairs 7 and 8, and finally transported by the second transport roller pairs 11 and 12. At this time,
Since the optical card 1 is not held between the cleaners, the required conveying force is very small.

The leading end of the optical card 1 in the insertion direction is placed on the mounting table 9.
Abuts against the stopper 9a of the second notch roller 1
1 and the surface 1c of the optical card 1 slip.

As described above, although the optical card 1 is transported, the first transport roller pairs 7, 8 and the optical card 1 do not slip with each other, but the second transport roller pairs 11, 12
Slip at the last stage of transport operation. For this reason, the second notch roller 11 is under more severe conditions than the first notch roller 7, and the wear progresses faster.

In this embodiment, the conveying force of the first conveying roller pairs 7 and 8 and the conveying force of the second conveying roller pairs 11 and 12 are set so as to satisfy the expression (1). The pinching force of the optical card 1 between the pair of conveying rollers 11 and 12 is smaller than the pinching force between the pair of first conveying rollers 7 and 8. Therefore, the load due to the pinching force of the second notch roller 11 can be reduced more than the load due to the pinching force of the second notch roller 11, so that the durability of the second notch roller pair can be improved.

Here, the second transport roller pair 1
Since the transport force of 1 and 12 is reduced, the force required to slip the second notch roller may be small, and the motor as the driving source can be reduced in size. As a result,
The size of the device can be reduced, and the power consumption when the optical card 1 is loaded can be reduced.

As shown in FIG. 4, at a position where the notch of the second notch roller forms an interval with the second roller 12, the rotation of the motor (not shown) is stopped and the optical card 1 is stopped.
Then, the loading operation to the mounting table 9 is ended. Here, FIG.
As shown in the figure, the second notch roller 11 and the optical card 1
Are not in contact with each other, the mounting table 9 can freely move in a direction perpendicular to the paper surface.

Thus, the optical head 14 reciprocates in the BB direction, and the mounting table 9 reciprocates in the direction perpendicular to the plane of the drawing to record and reproduce information. In this embodiment, the information recording / reproducing apparatus of the type in which the optical head reciprocates in the direction parallel to the optical card insertion direction and the mounting table reciprocates in the direction orthogonal to the optical card insertion direction has been described.

A first conveying roller pair, a second conveying roller pair disposed at a position corresponding to the mounting table, and an information recording medium detecting means on a side of the second conveying roller pair facing the cleaner. And The distance from the outer surface of the entrance to the information recording medium detecting means is shorter than the length of the information recording medium in the insertion direction, and at least one roller of each transport roller pair is a notch roller having a notch formed on the peripheral surface. In addition, when the information recording medium is inserted, the rollers of the first and second transport roller pairs are configured to form an interval equal to or greater than the thickness of the information recording medium. An information recording medium loading operation is performed based on an output signal when a side of the inserted information recording medium in the insertion direction is detected, and the first transport roller pair and the second transport roller pair are used. The information recording medium is transported to the mounting table, and after the information recording medium is positioned at a predetermined position, the second transport roller pair is slipped to perform positioning, and the transport force by the second transport roller pair is reduced by the second. 1 carry While smaller than the conveying force of the roller pair, the conveying force of the first conveying roller pair and the second
Is set to be larger than the frictional resistance of the cleaner.

Therefore, when the information recording medium is conveyed into the apparatus and when the information recording medium is held between the cleaners, the information recording medium always includes the first conveying roller pair and the second conveying roller. The pair is conveyed while being pinched.
Is greater than the frictional resistance of the cleaner, the information recording medium can be transported into the apparatus.
In addition, since the two pairs of conveying rollers cooperate to convey against the frictional resistance of the cleaner, the conveying force of each pair of conveying rollers can be reduced, and the durability of the conveying rollers is improved. Has advantages.

Further, the information recording medium is transported to the mounting table by the first transport roller pair and the second transport roller pair, and after the information recording medium is positioned at a predetermined position, the second transport roller pair is moved. Is slipped for positioning, and since the conveying force of the second conveying roller pair is smaller than the conveying force of the first conveying roller pair, after positioning the information recording medium at a predetermined position on the mounting table, The required force can be reduced when the second transport roller pair slips on the information recording medium. For this reason, it is possible to reduce the size of the motor that is the drive source, reduce power consumption, and achieve an advantage of downsizing the device. Further, since the conveying force of the second conveying roller pair is small,
Since the force for nipping the information recording medium between the second pair of conveying rollers can be reduced, the load on the conveying rollers can be reduced, and the durability of the second conveying rollers can be improved. .

When the conveying force of the first conveying roller pair is equal to the conveying force of the second conveying roller pair, the second conveying roller pair always slips when the information recording medium is loaded.
Although the durability was lower than that of the first conveying roller pair, in the present invention, the conveying force of the second conveying roller pair was made weaker than the conveying force of the first conveying roller pair. The durability can be made closer to the durability of the first transport roller, and there is an advantage that the loading durability of the information recording medium as an apparatus is improved.
