Is formed, and behind the recess 17, a substantially rectangular recess 19 for accommodating a magnetic head 21 described later is formed.

Next, the support structure of the touch roller, which is a feature of the present invention, will be described with reference to FIGS. 3 to 7. Reference numeral 20 denotes a side plate made of a flat metal, and as shown in FIG. 1, the concave portion 5 is formed so as to face the side force member 8 via the two bent portions 20a, 20a formed by bending. It is attached to the lower case 2 so as to be erected on one side portion. A magnetic head 21 is attached to the side plate 20 via a bracket 22 having a substantially U shape in a plan view, and the first reading unit 21a and the second reading unit 21a are provided on the upper surface of the magnetic head 21 formed in an arc shape. Reading unit 21b
Are formed.

As shown in FIG. 4, both side plates 22a, 22a of a bracket 22 to which both sides of the magnetic head 21 are fixed are shown.
Is formed so as to be inclined with respect to the bottom plate 22b fixed to the side plate 20 by the azimuth angle α of the magnetic information in the magnetic card 6 with respect to the card transport direction AB. Therefore, the first reading unit 21a and the second reading unit 21b of the magnetic head 21 also form an angle α with respect to the card transport direction AB.
The reading sections 21a and 21b are arranged so as to be inclined only by a distance δ with respect to the card transport direction AB. On the magnetic head 21, a first touch roller 30 and a second touch roller 31 rotatably supported by a shaft 24 pivotally supported by the side plate 20 are in contact with each other.

That is, as shown in FIGS. 5 (a) and 6, the shaft 24 has a base portion 25 formed in a substantially cylindrical shape, and one end surface of the base portion 25 is configured so that its axial centers are offset from each other. It is formed by a large-diameter first shaft portion 26 that is provided in a protruding manner, and a small-diameter second shaft portion 27 that is provided so as to protrude from an end surface of the first shaft portion 26. A small-diameter boss 25a is projectingly provided on the other end surface of the base portion 25, and a blind hole-shaped screw portion 25b is formed on the end surface of the boss 25a. The portion is chamfered, and the boss 25a is formed in a D-cut shape in a front view.

The axis of the first shaft portion 26 and the axis of the second shaft portion 27 are formed so as to be offset by δ, and an annular groove 27a is formed at the tip of the second shaft portion 27. There is. The first touch roller 30 and the second touch roller 31 are formed to have the same outer diameter.
In the center holes of the touch roller 31 of different inner diameters,
Sleeves 32 and 33 having flanges formed at both ends are fitted and inserted, respectively. In such a configuration, the shaft 24
The boss 25a of the base portion 25 of the
0a and screw the screw 28 through the washer 25
The shaft 24 is attached to the side plate 20 in a direction orthogonal to the card transport direction A-B by screwing the shaft 24 into the side plate 20. Rotation of the attached shaft 24 is regulated by the D-cut, and as shown in FIG. 6, the axis of the second shaft 27 is aligned with the axis of the first shaft 26 in the card transport direction. It is configured to be attached to the side plate 20 so as to be displaced by δ.

As described above, since the base portion 25 is formed in a D-cut shape so that the rotation of the shaft 24 is regulated, when the shaft 24 is attached to the side plate 20, the rotation direction of the shaft 24 is changed. Positioning is done. Therefore, the first shaft portion 2
The axis of the second shaft portion 27 is positioned with respect to the axis of 6 in the state of being accurately offset by δ in the card transport direction (arrow AB direction), so that the first and second axes will be described later. The first and second touch rollers 30 and 31 rotatably supported by the shaft portions 26 and 27 of the
Positioned exactly on a, 21b. Therefore, the first
Also, the reading failure by the second reading units 21a and 21b is prevented, and the assembling work of the shaft 24 is facilitated.

A first touch roller 30 is rotatably supported by being engaged with a first shaft portion 26 of the shaft 24 through a sleeve 32, and a second touch portion is supported on a second shaft portion 27 by a second touch. The roller 31 is rotatably supported by being engaged via the sleeve 33. The E ring 34 is engaged with the annular groove 27a of the second shaft portion 27, so that the first and second touch rollers 30 and 31 are prevented from coming off the shaft 24.

In this way, in order to position the first and second touch rollers 30 and 31 while displacing each other by δ,
Supporting with one shaft 24 not only reduces the number of shafts, but also eliminates the need for a mounting bracket.
The number of parts is reduced and the assembling work is simplified. In FIG. 1, reference numeral 35 denotes a support shaft that is erected above the rear portion side of the lower case 2 described above and in a direction orthogonal to the card transport direction AB.

Next, referring to FIG. 2, the upper case 3
Will be explained. The upper case 3 is formed in a shallow dish shape with an upper opening, and the hook portion 40 formed at the rear end is engaged with the support shaft 35 of the lower case 2 described above, so that the upper case 3 supports the support shaft 35. The front end portion is configured to be openable and closable in the direction of arrow C-D in the figure, with the center of rotation as the center of rotation. When the front end of the upper case 3 is rotated in the direction of the arrow D and the upper case 3 closes the upper part of the lower case 2, a magnetic field is generated between the bottom part 41 of the upper case 3 and the card carrying part 4 of the lower case 2. The card transport path 42 is formed at an interval slightly larger than the thickness of the card 6.

A window 43 is formed in the bottom portion 41 of the upper case 3 so as to face the window 11 of the lower case 2,
A pinch roller 45 facing the drive roller 12 of the lower case 2 is rotatably supported above the front end of the window 43. A pinch roller 46 facing the driven roller 13 is rotatably supported above the rear end of the window 43, and a driven belt 47 that is in contact with the drive belt 14 described above is interposed between the pinch rollers 45 and 46. It is stretched. 48 is a tension roller, 49 is a pinch roller 1
6 is a pinch roller that faces 6.

Next, a card processing operation in the card reader having such a configuration will be described. In FIGS. 1 and 2, when the magnetic card 6 is inserted through the card insertion / return port 10a, this is detected by a detection means (not shown), a motor (not shown) rotates in the forward direction, and the driving roller is driven. Since 12 rotates counterclockwise in FIG. 2, the drive belt 14 runs in the direction of arrow A. Following this running, the driven belt 47 that is in contact with the drive belt 14 also runs in the direction of arrow A, so that the magnetic card 6 is conveyed in the direction of arrow A so as to be sandwiched between these belts 14 and 47. It

When the magnetic card 6 is positioned on the magnetic head 21, the first and second touch rollers 30, 31 are placed.
The magnetic card 21 is pressed against the first and second reading units 21a and 21b of the magnetic head 21, and the magnetic information recorded on the magnetic card 6 is read.

When the magnetic card 6 is determined to be a normal card, the rotation of the motor is temporarily stopped, so that the magnetic card 6 stops on the card transport section 4. Then, when the service provided by the device equipped with the card reader 1 is completed, the motor rotates in the opposite direction and the magnetic card 6 is moved to the arrow B.
The magnetic head 21 conveys the value information such as the balance and rewrites the value information. After the rewriting, the punch unit 18 punches holes corresponding to the rewriting of the value information, and the punch holes are returned from the card insertion opening / return opening 10a.

In the present embodiment, the magnetic head 21
Of the first and second reading units 21a and 21b
However, the number may be three or more. Further, although two reading units are provided in one magnetic head, two or more magnetic heads each having one reading unit may be provided. Further, in order to restrict the rotation of the shaft 24 attached to the side plate 20, the boss 25a of the base portion 25 is formed in a D-cut shape, but it may be formed in an H-cut shape and various design changes are possible. is there.
