DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic head device provided in a processor for processing a magnetic information recording medium such as an automatic ticket gate.

2. Description of the Related Art Conventionally, a magnetic head device provided in a processing machine for processing a magnetic information recording medium (hereinafter, referred to as a "magnetic ticket") such as an automatic ticket gate machine has a transport system comprising a pair of endless belts. In the middle of the path, a magnetic head is provided on one side with the conveyance path in the middle, and a pinch roller is provided on the other side.

In the magnetic head device having the above configuration, when a magnetic ticket is conveyed on a conveying path, the magnetic ticket slides on the magnetic head while being pressed by a pinch roller, and data recorded on the magnetic ticket is read. Is read or magnetic data is written on the magnetic ticket.

However, in this conventional magnetic head device, since the magnetic ticket is pressed against the magnetic head by a pinch roller, the pressing is performed by a line, so that the state in which the magnetic ticket is pressed against the magnetic head is improper. There was a problem that the system was likely to be stable, and stable reading and writing could not be expected.

[0005] In order to solve such a problem, the present applicant has proposed a belt type in which a magnetic ticket can be pressed by a rotating pressing belt instead of a conventional pinch roller. In the magnetic head device according to this proposal, the magnetic ticket can be pressed against the magnetic head by the rotating pressing belt, so that the pressed state is flat, the pressed state of the magnetic ticket against the magnetic head is stable, and the reading process and the writing process can be performed. There is a feature that can be performed well.

[0006]

As described above, when the pinch roller of the magnetic head device is formed as a rotating pressing belt, the pressing state of the magnetic ticket against the magnetic head becomes a surface, so that the reading performance and the writing performance are improved. Can be increased,
Even in this belt type, the magnetic head surface is soiled due to long-time use, so it is necessary for an attendant to periodically clean the magnetic head surface. If this cleaning is neglected, a reading error or a writing error is likely to occur. Therefore, the cleaning of the magnetic head surface by the attendant is indispensable, and there is a disadvantage that the burden on the attendant increases.

The present invention has been made in order to solve the above-mentioned drawbacks, and an object of the present invention is to provide a magnetic head device capable of automatically cleaning a magnetic head surface.

[0008]

In order to achieve the above object, a magnetic head device according to the present invention has a magnetic head on one side in the middle of a transport path for transporting a magnetic ticket with the transport path in the middle. A magnetic head device that performs a reading process or a writing process by providing a rotating pressing belt on the other side and pressing a magnetic ticket conveyed in the conveying path against the magnetic head with the rotating pressing belt. So,
Driving means for rotating the pressing belt is provided while the pressing belt is not pressing the magnetic ticket toward the magnetic head. Further, a groove is provided on the magnetic head side of the pressing belt.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a magnetic head device according to one embodiment. The transport path L includes a pair of endless belts, and a magnetic head H is provided on one side (lower side in FIG. 1) of the transport path L in the middle of the transport path L. Have been. The transport path L is provided in a groove (not shown) provided in the magnetic head H.

On the other side of the transport path L in which the magnetic head H is provided, rollers R,
R, a pressing belt B stretched around R is provided. When the magnetic head H is viewed from a plane, a pair of the pressing belts B are provided with the conveyance path L being in the middle.

A motor M is provided on the rotating shaft of one of the three rollers R (R, R, R in the example of FIG. 1). Therefore, when the motor M is driven to rotate, the pressing belt B can be rotated (see FIG. 2B described later). The rotation of the pressing belt B may be performed via a clutch mechanism from the drive source of the transport path L without providing the motor M.

A plurality of grooves 1, 1... As shown in FIG. 2A are provided on the surface of the pressing belt B on the side in contact with the magnetic head H. The grooves 1, 1,... Are provided so as to be orthogonal to the moving direction of the pressing belt B (see the arrow) and at a predetermined interval. FIG.
(B) shows grooves 2, 2,... Of other shapes, which are formed so as to protrude in the direction of movement of the pressing belt B.

The groove 1 as described above is formed on the surface of the pressing belt B.
Since (or 2) is provided, when this surface slides on the magnetic head H, the magnetic head H has a feature of being efficiently cleaned.

The cleaning control operation of the magnetic head device having the above configuration will be described with reference to FIGS. now,
It is assumed that the magnetic ticket A is being conveyed toward the magnetic head H via the conveyance path L (see FIG. 3A).

When it is detected by a sensor (not shown) that the conveyance of the magnetic ticket a has reached a predetermined distance before the magnetic head H,
The motor M starts rotating, whereby the pressing belt B starts rotating. Thus, the magnetic head H is cleaned by the rotation of the pressing belt B (see FIG. 3B).

When the magnetic ticket A is pressed against the magnetic head H by the pressing belt B, the rotation of the motor M is stopped. The pressing belt B is rotated in the same manner as when it is moved by the motor M while being accompanied by the magnetic ticket A conveyed by the conveying path L (see FIG. 3C).

When the magnetic ticket A comes off the magnetic head H, the rotation of the pressing belt B due to the accompanying magnetic ticket A is stopped (see FIG. 3D), and the next magnetic ticket B is awaited.

As described above, since the magnetic head H is automatically cleaned by the pressing belt B, it is possible to omit a regular cleaning work by a person in charge of the related art.

[0019]

According to the magnetic head device of the present invention, the driving means for rotating the pressing belt is provided while the pressing belt is not pressing the magnetic ticket toward the magnetic head.
The cleaning is automatically performed by the pressing belt, so that the regular cleaning work by the attendant as in the related art can be omitted. Further, when grooves are provided on the magnetic head side of the pressing belt, the cleaning effect can be enhanced.
