Abstract

PURPOSE:To accurately read out information by forming a 2nd carrying means on the insertion port side from a magnetic head independently of a 1st carrying means. CONSTITUTION:When a motor 31 is rotated, driving rollers 9, 47 are rotated in the inserting direction, and when a magnetic card 3 is inserted from the insertion port 5 into a guide case 1, the card 3 is held between the driving roller 47 and an idler 49 and carried to the magnetic head 19 side. The carrying speed is a fixed speed proper for reading out information from a magnetic stripe surface 13. When the card 3 is reached between the driving roller 9 and an idle roller 11, the card 3 is carried by the driving force of the roller 9 and the head 19 reads out the information on the magnetic stripe surface 13. At that time, the roller 9 is raised by the thickness of the card 3 and a frame 43 is rotated together with a subframe 59. Since the distance of the subframe 59 from a fulcrum 45 is longer than that of the frame 43, the driving roller 47 is raised and separated from the card 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to, for example, a portable medium reading device, and more particularly to a reading device with an improved portable medium transport mechanism.

(Prior Art) As a conventional portable medium reading device, there is one shown in FIG. 5, for example. In the device shown in FIG. 5, a guide case 101 is provided with an insertion slot 105 for inserting a magnetic card 103, which is a portable medium, and a magnetic head 107 for reading information on the card 103.

A motor 109 is provided inside the guide case 101, and a drive roller 111 is connected to a drive shaft of the motor 109. The drive roller 111 is in contact with an idle roller (not shown), and the magnetic card 103 is conveyed within the guide case 101 by sandwiching the magnetic card 103 between both rollers.

The magnetic head 107 picks up the magnetic card 103 using the bin 113.
This causes the magnetic head 107 to slide relative to the magnetic stripe surface 115 of the magnetic card 103 to read information.

By the way, the magnetic head 10 is installed in the guide case 101.
7 is disposed on the side of the insertion port 105, thereby reducing the size of the entire reading device. On the other hand, the magnetic stripe 115 of the magnetic card 103 is formed from one edge of the magnetic card 103 to the other edge. Therefore, when the magnetic card 103 is inserted into the guide case 101, the information on the magnetic stripe surface 115 is immediately read.

However, the magnetic card 10 to the guide case 101
3 is inserted manually, so
The beginning of reading Magnetic Strive 115 is magnetic card 103.
If the conveyance speed is slow or uneven, there is a risk that the magnetic head 107 will not be able to read the magnetic information accurately.

On the other hand, it is conceivable to simply provide another driving roller and an idle roller closer to the insertion slot 105 than the magnetic head 107 and to convey the magnetic card 103 at an even and moderate conveying speed.

However, in the above-mentioned reading device, the driving force of the drive roller 111 and the other drive rollers interferes with each other, causing the conveyance speed to fluctuate, which may make accurate reading difficult. Furthermore, since the magnetic card 103 is driven forward and backward in the conveyance direction, the conveyance resistance is large and the durability of the motor 109 and the like is reduced. Furthermore, there is a problem in that so-called jitter occurs due to slight differences in rotational speeds of the re-driving rollers.

(Problems to be Solved by the Invention) As mentioned above, in the conventional portable medium reading device,
Accurate reading was difficult because the magnetic head was located on the insertion port side of the main body.

This invention was made in view of the above problem, and aims to provide a portable medium reading device that can accurately read information while having a configuration that suppresses fluctuations in conveyance speed without impairing durability. do.

[Configuration of the Invention (Means for Solving the Problems)] In order to achieve the above object, the present invention provides an insertion port provided in a main body for inserting a portable medium, and a side of the insertion port of the main body. reading of a portable medium, comprising: a first conveying means provided in the holder for holding and conveying the portable medium; and an information reading means for reading information on the portable medium conveyed by the first conveying means. In the device U, a second conveying means is provided which is located closer to the insertion opening than the information reading means and which grips and conveys the portable medium.
The transport means is configured to separate from the portable medium when the portable medium is being transported by the first transport means.

(Function) In the above configuration, when a portable medium is inserted through the insertion opening of the main body, the second conveyance means conveys the portable medium to the information reading means side, so that a stable conveyance speed can be obtained.

Further, since the second conveying means separates from the portable medium while the first conveying means is conveying the portable medium,
The first and second conveyance means do not interfere.

(Example) Examples of the present invention will be described in detail below based on the drawings.

1 and 2 show a portable medium reading device according to an embodiment of the present invention.

Here, Fig. 1 is a schematic plan cross-sectional view, and Fig. 2 is a schematic cross-sectional view of Fig. 1.
−■ It is a sectional view.

In Figures 1 and 2, the guide case 1 which is the main body
has an insertion slot 5 for inserting a magnetic card 3 as a portable medium, and a slot 5 for inserting the magnetic card 3 in communication with the insertion slot 5.
A conveyance path 7 is formed in which the materials are conveyed.

On the insertion port 5 side of the conveyance path 7, a drive roller 9 made of an elastic material such as rubber and an idle roller 11, which is a driven roller, are arranged facing each other. The drive roller 9 is driven in a forward and reverse direction, and the idle roller 11 is configured to be rotatable. Such drive roller 9 and idle roller 11 are in contact with each other in FIG.
The magnetic card 3 is sandwiched between them, and by rotating the drive roller 9 in the forward and reverse directions, the magnetic card 3 is inserted into the transport path 7 (rightward in the figure) or ejected (leftward in the figure). Furthermore, when the magnetic card 3 is sandwiched between both rollers 9 and 11, the drive roller 9 is raised by the thickness of the magnetic card 3. Note that the driving roller 9 and the idle roller 11 constitute a first conveyance means.

A magnetic stripe 13 is formed on the magnetic card 3. The magnetic stripe surface 13 is formed in the conveyance direction of the magnetic card 3, and various types of information are stored therein.

One end of a leaf spring 15 is fixed to the guide case 1 by a fixing screw 17, and a magnetic head 19 serving as an information reading means is attached to the other end of the leaf spring 15 with both rollers 9 and 11 in the conveyance direction of the magnetic card 3. They are supported at approximately the same position. A head surface 21 of the magnetic head 19 faces into the transport path 7 and is capable of sliding contact with the magnetic stripe surface 13 of the magnetic card 3. Then, the magnetic card 3 is transferred to the transport path 7 by both rollers 9 and 11.
The structure is such that the magnetic head 19 reads information on the magnetic stripe surface 13 by conveying the inside.

The drive roller 9 is connected to one end of the first shaft 23. A forward rotation gear 25 or a reverse rotation pulley 27 is selectively connected to the other end of the first shaft 23 by a switching mechanism (not shown). The forward rotation gear 25 is meshed with the reverse rotation gear 29.
9 is a drive gear 35 connected to the drive shaft 33 of the motor 31
is engaged with. A belt 39 is wound around the reversing pulley 27 around a boo 937 coaxial with the reversing gear 29. Therefore, by rotating the motor 31 and switching the switching mechanism, the drive roller 9 can be rotated in the forward and reverse directions via the gears 35, 29, 25, etc.

The motor 31 is fixed on a support base 41 provided on the guide case 1. On the other hand, the gears 29 and 25 are pivotally supported by the frame 43 along with the drive roller 9, the first shaft 23, and the like. The frame 43 has a fulcrum 45 provided in the guide case 1 and located coaxially with the drive shaft 33 of the motor 31.
It is rotatably supported around the center. Therefore, when the magnetic card 3 is held between the drive roller 9 and the idle roller 11, the drive roller 9 will rise by the thickness of the magnetic card 3, and the frame 43 will rotate about the fulcrum 45.

In the conveyance path 7 of the guide case 1, a driving roller 47 and an idle roller 49, which is a driven roller, are disposed facing each other at both ends of the conveyance path 7 on the side closer to the insertion port 5 than the magnetic head 19. Both rollers 47 and 49 are made of an elastic material such as rubber, and are capable of holding both ends of the magnetic card 3.

The drive rollers 47, 47 are connected to both ends of the second shaft 51, respectively. A pulley 53 is connected to an intermediate portion of the second shaft 51, and a boo 955 is also connected to an intermediate portion of the first shaft 23. A belt 57 is wound between both pulleys 53 and 55, so that the drive roller 9 and the drive roller 47 move in the same direction. On the other hand, the idle roller 49 is configured to be rotatable.

Drive roller 47 and idle roller 49 are in contact with each other in FIG. The magnetic card 3 is conveyed within the conveyance path 7 by rotating the drive roller 47 in forward and reverse directions with the magnetic card 3 sandwiched between the rollers 47 and 49.

Further, when the magnetic card 3 is sandwiched between the rollers 47 and 49, the drive roller 47 is raised by the thickness of the magnetic card 3. Note that the drive roller 47 and idle roller 49 constitute a second conveyance means.

The second shaft 51 is pivotally supported by a subframe 59. The sub-frame 59 is biased in the direction of holding the magnetic card 3 by a leaf spring 63 whose one end is fixed to the guide case 1 with a fixing screw 7 . A restraining piece 61 is provided between the subframe 59 and the frame 43, and the rotation of the subframe 59 in the direction of holding the magnetic card 3 with respect to the frame 43 is restrained. Also. Conversely, the drive roller 47
When the magnetic card 3 is held between the idle roller 49 and the idle roller 49,
The drive roller 47 rises, and the subframe 59 moves to the fulcrum 45.
It is configured to rotate around the center. Note that the drive rollers 9 and 47 are biased by a leaf spring 63 in a direction to sandwich the magnetic card 3.

Further, the sub-frame 59 is rotated about the fulcrum 45 by the restraining piece 61 in conjunction with the frame 43 rotating in the direction to release the magnetic card 3 from being held. Therefore,
When the magnetic card 3 is held between the drive roller 9 and the idle roller 11, the frame 43 and the subframe 59 rotate about the fulcrum 45.

Next, the operation will be explained based on FIGS. 3 and 4.

In the above configuration, when the motor 31 is rotated, the drive rollers 9 and 47 rotate in the same direction (insertion direction). In this state, when the magnetic card 3 is inserted into the card case 1 through the insertion slot 5, it is sandwiched between the drive roller 47 and the idle roller 49, and the magnetic card 3 is conveyed to the magnetic head 19 side. This conveyance speed is appropriate for the magnetic head 19 to read information on the magnetic stripe surface 13, and there is no unevenness in the speed as would be the case with manual operation.

Thereafter, when the magnetic card 3 reaches between the drive roller 9 and the idle roller 11, the magnetic card 3 is conveyed by the driving force of the drive roller 9, and the magnetic head 19 reads the information on the magnetic stripe surface 13.

At this time, the drive roller 9 rises by the thickness of the magnetic card 3, and the frame 43 rotates together with the subframe 59. Since the subframe 59 has a longer distance from the fulcrum 45, the drive roller 47 rises and separates from the magnetic card 3.

Therefore, when the magnetic card 3 is being conveyed by the drive roller 9 side, the driving force on the drive roller 47 side is not transmitted to the magnetic card 3. Therefore, the driving forces of the drive rollers 9 and 47 do not interfere with each other, and accurate and stable reading can be performed without fluctuations in the conveyance speed. Furthermore, the transport resistance of the magnetic card 3 can be kept low, and the durability of the motor 31 is not impaired. Furthermore, the drive roller 9
Since the driving forces of .degree. 47 do not interfere with each other, it is possible to suppress jitter of the magnetic card 3 caused by a slight difference in the rotational speed of both rollers 9 and 47.

Furthermore, after the magnetic head 19 has finished reading the information on the magnetic card 3, the drive roller 9° 47 is rotated in reverse (
discharge direction). Then, the magnetic card 3 is moved to the driving roller 9.
is conveyed in the discharge direction by the driving force of. When the magnetic card 3 is conveyed from the drive roller 9 and the idle roller 11 to the insertion slot 5 side, the frame 43 and the sub-frame 59 rotate in a direction to sandwich the magnetic card 3, and the drive roller 9 descends to remove the magnetic card 3. is held and conveyed in the discharge direction.

In this way, even when the magnetic card 3 is ejected, the durability of the motor 31 is not impaired and jitter can be suppressed as in the case when the magnetic card 3 is inserted.

Note that the present invention is not limited to the device of the above embodiment; for example, instead of the leaf spring 63, the frame 43 and the subframe 5 are used.
It goes without saying that the same effect can be obtained even if the plate spring 15 for urging the magnetic head 19 is constructed of a pin or a spring.

Further, a plurality of drive rollers 47 may be provided, and other configurations may be used as the first and second conveyance means. In this case, for example, a movable holding means for holding the magnetic card 3 may be provided near the insertion slot 5, and the magnetic card 3 may be transported by moving this holding means, for example, by a link mechanism.

[Effects of the Invention] As explained above, according to the present invention, since the second transport means is provided on the insertion port side of the magnetic head in addition to the first transport means, the transport speed of the portable medium is stabilized. Can read information accurately. Also, the first and second
The transport means of the portable medium do not interfere with each other, and fluctuations in the transport speed of the portable medium and occurrence of jitter can be suppressed, and the durability of the transport means can be maintained.
