{MEDIUM HANDLING DEVICE}

The present invention relates to a medium handling apparatus.

A medium handling apparatus for handling a medium such as a magnetic card or an IC card includes a first rotation conveying section for conveying the medium by rotation and a second rotation conveying section for conveying the medium by rotating the medium with the first rotation conveying section interposed therebetween And a second rotation conveying section for conveying the second rotation conveying section. Generally, a rubber having a high hardness is used in the rotating transporting portion to be driven, in order to secure the transportation by increasing the frictional force with the medium and to suppress the deformation caused by the pressing from the rotating transporting portion formed as a pair. A material such as rubber or plastic is used for the rotating transporting portion to follow, in order to prevent the surface of the medium from being scratched.

In the state in which the medium is not being conveyed, the first rotation conveying section and the second rotation conveying section are provided at the narrowing section (clamping section), which is a section where the first rotation conveying section and the second rotation conveying section sandwich the opposite report medium, There is a media handling device in contact. In such a medium handling apparatus, when the first rotation conveying section and the second rotation conveying section are formed of elastic bodies such as rubber, the following problems arise. That is, when the medium having a predetermined thickness is inserted into the narrow-width portion, or when the medium is discharged from the narrow-width portion, since the first rotation conveying portion and the second rotation conveying portion are deformed, . The fluctuation of the conveying speed may interfere with reading of the IC in the magnetic card or the IC card in the magnetic card.

In order to suppress such fluctuation of the conveying speed, there is a medium handling apparatus in which a gap is provided beforehand between the first rotating conveying section and the second rotating conveying section in the narrowing section. In such a medium handling apparatus, when a medium (such as a sheet or a film) thinner than the gap is inserted, the thin medium can not be transported and can not be half-returned (returned). In the medium conveying mechanism disclosed in Patent Document 1, a gap is provided between the first rotation conveying portion and the second rotation conveying portion, and a conveying portion for conveying a thin medium in addition to the first rotation conveying portion and the second rotation conveying portion is separately provided It is possible to make a half of a thin medium by installation.

A. First Embodiment:

1 is a diagram showing an outline of a card processing apparatus 100 according to an embodiment of the present invention. FIG. 1 shows XYZ axes which are mutually orthogonal. The XYZ axis in FIG. 1 corresponds to the XYZ axis in the other drawings. The card processing apparatus 100 processes the card 108. In the present embodiment, the card processing apparatus 100 corresponds to a " medium handling apparatus ". In the present embodiment, the card 108 is an IC card which is a card in which an integrated circuit (IC) is assembled. The card processing apparatus 100 includes a card insertion portion 101, a main body processing portion 102, and a card recovery portion 103. [

The card 108 is inserted into the card insertion portion 101. The card insertion portion 101 is provided with a magnetic head 109. The magnetic head 109 performs card information reading and writing processing.

The main body processing unit 102 processes the inserted card 108. Fig. The main body processing section 102 includes a sensor 104, a conveying motor 105, a two-stage pressing mechanism 300, and an IC head 110. The sensor 104 detects the inserted card 108 and outputs a signal to a control unit (not shown). The transport motor 105 is operated based on an instruction from the control unit which has received the signal. The card recovery unit 103 performs recovery of a card used illegally.

The two-stage pressing mechanism 300 has a structure for pressing in two steps according to the thickness of the medium to be conveyed. The two-stage pressing mechanism 300 includes a driving roller 301 and a driven roller 302. The driving roller 301 is driven in accordance with the power from the driven conveying motor 105. The follower roller 302 receives the card 108 with the drive roller 301 interposed therebetween and conveys it.

The IC head 110 performs card information reading and writing processing. In the present embodiment, the reading and writing process of the medium conveyed by the driving roller 301 and the driven roller 302 is performed.

When the medium 201a (sheet or film or the like) thinner than a predetermined thickness is transported by the drive roller 202 and the driven roller 203, the medium 201a is weakly pressed by the weak spring 205. [ When the medium 201b having a predetermined thickness is transported by the drive roller 202 and the driven roller 203, the holding portion 204 holding the driven roller 203 is moved to the Z axis Direction to the negative side. The displaced holding portion 204 presses the strong spring 206 so that the strong spring 206 strongly urges the driven roller 203 to the driving roller 202 through the holding portion 204. [ As a result, the medium 201b is strongly pressed.

However, in the two-stage pressing mechanism 200 shown in Fig. 2, in order to realize an appropriate gap and pressure between the holding portion 204 and the strong spring 206, a high precision assembly and high precision parts Is required. In addition, a sufficient conveying force may not be obtained due to a change in the component of the year.

The components constituting the driven roller 302 side facing the drive roller 301 are driven by the card processing device 100 through the fixed bracket 308 fixed to the drive roller 301. In this embodiment, As shown in Fig. In another embodiment, the component constituting the driven roller 302 side may be fixed to a stable position such as a conveying guide through the fixing bracket 308. [ In this embodiment, the fixing bracket 308 corresponds to " fixing portion ".

The drive roller 301 feeds the medium by sandwiching the medium together with the driven roller 302 and rotating together with the driven roller 302. In this embodiment, the drive roller 301 is driven by the conveying motor 105. [ In this embodiment, the driving roller 301 and the driven roller 302 sandwich the facing medium therebetween. In this embodiment, the drive roller 301 corresponds to a " first rotation conveying portion ".

The driven roller 302 sandwiches the medium with the drive roller 301 and transports the medium as the medium is transported by the drive roller 301. [ In this embodiment, the driven roller 302 is disposed on the -side of the driving roller 301 in the Z-axis direction. In another embodiment, the driven roller 302 may be disposed on the positive side of the driving roller 301 in the Z-axis direction. In this embodiment, the driven roller 302 corresponds to the " second rotation conveying portion ".

In this embodiment, the adjustment shaft 305 is a bolt. The adjusting nut (306) is screwed to the adjusting shaft (305). In this embodiment, the adjustment shaft 305 and the adjustment nut 306 correspond to an " adjustment unit ".

Fig. 4 shows a cross section of the two-stage pressing mechanism 300 seen from the arrow F4-F4 in Fig. 3 (b). In this embodiment, the adjustment shaft 305 is formed in the through hole formed in the driven roller holder 303, the through hole formed in the sliding bush 307, the inside of the compression spring 310, A bolt hole, and an adjusting nut 306 are inserted. The adjustment shaft 305 through which these members are inserted is fastened to the fixing bracket 308 by an adjustment nut 306. [ The position of the adjusting shaft 305 with respect to the fixing bracket 308 can be changed in the range along the axial direction of the adjusting shaft 305 by turning the adjusting shaft 305 which is a bolt.

The position of the pressing portion 305a is changed and the sliding bush 307 is also pressed to change the position in accordance with the positional change in the range along the axial direction of the adjusting shaft 305. However, The distance d is adjusted by not being displaced. Therefore, the distance d can be adjusted according to the thickness of the medium to be inserted. Further, it is possible to individually adjust the deviation of the distance d due to the assembly of the plurality of two-stage pressing mechanisms 300, the deviation of the part precision, and the change of the aged parts.

As a result, the conveyance of the stable medium 311 can be realized.

When the medium (sheet or film or the like) thinner than a predetermined thickness is inserted, the state of the two-stage pressing mechanism 300 in Figs. 5 and 6 is the same as that in the state in which the follower roller 302 is in contact with the torsion spring 309, , It is possible to transport the thin medium because it is pressed toward the + side in the Z-axis direction. The moment when the medium is ejected is the same as the two-stage pressing mechanism 300 in the state of Fig. 6, and the driven roller 302 is pressed to the plus side in the Z-axis direction only by the torsion spring 309 , The fluctuation of the conveying speed at which the medium is conveyed can be reduced.

According to the embodiment described above, when the medium to be inserted is not sandwiched between the first rotation conveying portion and the second rotation conveying portion, the second rotation conveying portion is lightly pressed from the first elastic body, The fluctuation can be suppressed. Further, when a thinner medium than the medium to be inserted is inserted, the thin medium can be half-angle without separately forming the carry section. When the medium to be inserted between the first rotation conveying portion and the second rotation conveying portion is fitted, the second rotation conveying portion is strongly pressed from the second elastic body, so that stable conveyance of the medium can be realized.
