Description

The present invention relates to a magnetic reader / writer.

An automated teller machine (ATM) or other automated teller machine or POS (Point Of Sales) terminal device may have a built-in or adjacent magnetic reader / writer. The magnetic reader / writer is a magnetic stripe formed on the plate surface (including the paper surface) of a plate-shaped (including paper leaf-shaped and booklet-shaped) medium such as a magnetic card or a passbook so as to extend in a layered and longitudinal direction. On the other hand, it is a device that reads and writes magnetic data (reads and writes magnetic data).

Generally, a magnetic reader / writer supports a medium transport path for transporting a medium in a transport direction and a surface provided on the medium transport path on which a magnetic stripe of the medium is formed so that the medium can be taken in and out of the magnetic reader / writer. A medium support section, a magnetic head that reads and writes magnetic data to and from the magnetic stripes of the medium supported by the medium support section, and a magnetic head provided to the medium support section in particular on the medium transport path and with respect to the magnetic stripes of the medium. Has an opening for the head through which the magnetic head passes so that the magnetic head can be contacted or approached.

When reading and writing magnetic data to and from the magnetic stripe, the medium and the magnetic head need to move relatively in the extending direction of the magnetic stripe. Specifically, there are a magnetic reader / writer configured to move the medium while reading and writing magnetic data, and a magnetic reader / writer configured to move the magnetic head.

By the way, dirt or dust may be attached to the medium inserted into the magnetic reader / writer in order to read / write magnetic data. Dirt and dust adhering to the medium may peel off from the medium and fall when the medium is conveyed on the medium transport path. Dirt and dust that have fallen from the medium may be mixed as foreign matter further inside the magnetic reader / writer, that is, inside the magnetic reader / writer and outside the medium transport path, through the above-mentioned opening for the head.

In particular, in the magnetic reader / writer configured to move the magnetic head, including those disclosed in Patent Documents 1 and 2, the opening for the head opens in a long range according to the moving range of the magnetic head. ing. Therefore, there is a high possibility that foreign matter will be mixed.

Usually, a moving mechanism of a magnetic head, an electric circuit board, and the like are mounted further inside the magnetic reader / writer. Therefore, the moving mechanism of the magnetic head may bite a foreign substance and hinder the movement of the magnetic head, or the moving mechanism of the magnetic head may be damaged. In addition, foreign matter may short-circuit the electric circuit and damage the circuit components. Therefore, it is desired to take measures against foreign matter entering through the opening for the head.

As a countermeasure against foreign matter entering through the head opening, for example, a measure of providing a shutter that closes the head opening when the magnetic head is not used can be considered. However, since a mechanism for opening and closing the shutter is required depending on the use / non-use of the magnetic head, the structure of the magnetic reader / writer becomes complicated, and there are concerns about an increase in manufacturing cost, a decrease in maintainability, a decrease in durability, and the like. ..

Therefore, an object of the present invention is to provide a magnetic reader / writer which has a simple structure but can prevent foreign matter from entering through the opening for the head.

According to the present invention, it is a magnetic reader / writer that reads and writes magnetic data on a magnetic stripe formed in a layered manner on the plate surface of a plate-shaped medium so as to extend in the longitudinal direction. It is movable in the approaching / detaching direction perpendicular to the surface of the magnetic stripe of the medium supported by the medium support portion and the medium support portion that supports the plate surface of the medium, and is also movable in the longitudinal direction of the magnetic stripe. A magnetic head that is configured to be movable in a slide direction parallel to the magnetic stripe and reads and writes magnetic data while moving in the slide direction while in contact with or in close contact with the magnetic stripe, and a magnetic head of the magnetic head in the slide direction. It has a head opening that opens within a range corresponding to the movement range and allows the magnetic head to pass through the magnetic stripe of the medium supported by the medium support so as to be in contact with or close to the magnetic stripe. The head opening includes a pair of long sides parallel to the sliding direction and a pair of short sides orthogonal to the long side of the pair, and the lengths of the head opening facing each other from the long sides of the pair. A plurality of brush pieces extending in parallel toward the side to the middle portion between the short sides of the pair further have a brush portion formed in parallel over the long side, and the plurality of brush pieces of the brush portion. When reading and writing magnetic data, a magnetic reader / writer is obtained that is displaced by the magnetic head so as to be reversibly deformed so as to be in contact with the side surface of the magnetic head.

According to the present invention, an automated teller machine having the magnetic reader / writer and the medium being a passbook can be obtained.

In FIG. 3, reference numeral 50H indicates a first head drive mechanism that drives the magnetic head 20 in the approach / detachment direction H. Reference numeral 50W indicates a second head drive mechanism for driving the magnetic head 20 in the slide direction W, respectively. In the drawings other than FIG. 3, the first head drive mechanism 50H and the second head drive mechanism 50W are not shown.

The magnetic head 20 has a non-working position (position shown in FIG. 3) that is separated from the magnetic stripe 101 and does not read or write magnetic data, and a read / write position (position that is in contact with or close to the magnetic stripe 101) in the approach / detachment direction H. It is possible to move between the position shown in FIG. 4). The magnetic head 20 also has a retracted position (position shown in FIG. 3) outside (right side in FIG. 4) of one end 101p of the longitudinal direction W of the magnetic stripe 101 in the sliding direction W, and a longitudinal direction of the magnetic stripe 101. It is movable between the other end of W and the other end 101d (FIG. 4).

In the brush portion 30, a plurality of brush pieces extending from each of the long sides of the pair of the head opening 11 to the intermediate portion between the short sides of the pair toward the opposite long sides are arranged in parallel over the long sides. It consists of. The brush portion 30 has a front end surface 20T (see FIGS. 5A and 5B) that reads and writes magnetic data of the magnetic head 20 in a non-working position (position shown in FIG. 3) in the approaching / detaching direction H. And it is provided at the same position.

Moreover, the brush portion, which does not require a power source, has a simple structure and can be manufactured at low cost, as compared with the case where the opening for the head is provided with a shutter mechanism that automatically opens and closes as needed.

As shown in FIGS. 5A and 5B, the plurality of brush pieces of the brush portion 30 are used when reading and writing magnetic data, that is, as shown in FIG. 4 when the magnetic head 20 is in the approaching / detaching direction H. By being pushed away by the magnetic head 20 in the read / write position, the shape is reversibly deformed so as to come into contact with the side surface 20S of the magnetic head 20. As a result, when reading and writing the magnetic data, the brush piece does not intervene between the magnetic stripe 101 and the tip surface 20T for reading and writing the magnetic data of the magnetic head 20, and the magnetic data is read and written. It does not interfere with writing. In the drawings other than FIGS. 5A and 5B showing the magnetic heads in the read / write position in the approach / detachment direction (for example, FIG. 4), the brush pieces are deformed for the purpose of avoiding the complexity of the illustration. I'm drawing it as if it weren't.

At this time, the magnetic head 20 is in the inactive position in the approach / detachment direction H and in the retracted position in the slide direction W.

Next, the magnetic head 20 is driven by the first head drive mechanism 50H (FIG. 3) and moves to the read / write position as shown by the broken line in FIG. 7. At this time, since the magnetic head 20 penetrates the brush portion 30 upward, the tip surface 20T (FIGS. 5A and 5B) is cleaned. That is, in FIG. 7, the magnetic head 20 shown by the broken line is in the read / write position in the approach / detachment direction H and in the retracted position in the slide direction W.

Next, the magnetic head 20 is driven by the second head drive mechanism 50W (FIG. 3), and as shown by the solid line in FIG. 7, from the retracted position toward the other end 101d of the magnetic stripe 101 in the slide direction W. While moving, the magnetic data already recorded on the magnetic stripe 101 is read (read). The magnetic head 20 moves in the slide direction W while pushing away the brush portion 30, but as shown in FIGS. 5A and 5B, the brush piece of the brush portion 30 comes into contact with the side surface 20S of the magnetic head 20. The brush portion 30 does not ride on the tip surface 20T (FIGS. 5A and 5B) of the magnetic head 20, that is, does not enter between the magnetic stripe 101 and the magnetic head 20. Therefore, a read error does not occur due to a decrease in the magnetic read output.

When the magnetic head 20 reaches the other end 101d of the magnetic stripe 101 (strictly speaking, the end of the recording area in front of the other end 101d) and the reading from the magnetic stripe 101 is completed, the magnetic head 20 is moved to the first position. It is driven by the head drive mechanism 50H (FIG. 3) of No. 1 and moves to a non-working position as shown in FIG. That is, in FIG. 8, the magnetic head 20 is in a non-working position in the approach / detachment direction H and is in a position corresponding to the other end 101d of the magnetic stripe 101 in the slide direction W. Further, at this time, the tip surface 20T (FIGS. 5A and 5B) of the magnetic head 20 is at the same height as the brush portion 30 in the approaching / detaching direction H.

Next, the magnetic head 20 is driven by the second head drive mechanism 50W (FIG. 3), and as shown in FIG. 9, from the position corresponding to the other end 101d of the magnetic stripe 101 in the slide direction W, in the figure, Move toward the retracted position on the right side. At this time, since the tip surface 20T (FIGS. 5A and 5B) of the magnetic head 20 is at the same height as the brush portion 30 in the approach / detachment direction H, the tip surface 20T is cleaned.

Next, as shown by the solid line in FIG. 9, the magnetic head 20 is in the inactive position in the approach / detachment direction H and returns to the retracted position in the slide direction W.

As described above, the reading of the magnetic data already recorded on the magnetic stripe of the medium is completed.

By the way, when writing magnetic data to the magnetic stripe of the medium, in order to verify that the writing was performed correctly after writing to the magnetic stripe, the magnetic head 20 slides in the sliding direction W as shown in FIG. Perform verification reading (verify read) while returning and moving in. That is, when writing magnetic data to the magnetic stripe of the medium, first, when the magnetic head 20 moves from the non-working position to the reading position in the approaching / detaching direction H, the magnetic head 20 is moved by the brush portion 30. The tip surface 20T (FIGS. 5A and 5B) is cleaned, but the tip surface 20T (FIGS. 5A and 5B) is not cleaned when the magnetic head 20 moves in the sliding direction W.

However, normally, when writing magnetic data to the magnetic stripe of the medium, the magnetic data is read from the magnetic stripe of the medium prior to this, so cleaning while the magnetic head moves in the sliding direction is also possible. Will be done. Therefore, even if cleaning is not performed at the time of writing, there is no problem in operation.
