As shown in FIG. 4, an operation panel 110 is provided on the surface of the exterior cover, and a plurality of operation switches are arranged therein. As an example, by operating the operation switch 110a, A cleaning process to be described later can be started.

FIG. 5 is a block diagram showing a configuration of a control system according to the present embodiment. FIG. 6 is a flowchart illustrating a control method of the printing apparatus according to the present embodiment.

As shown in FIG. 5, in this embodiment, a control circuit section 100 for controlling the magnetic reading device 20 and the printing mechanism section 90 is provided. The operation panel 110 and the magnetic reading head 3 of the magnetic reading device 20
0, magnetizing motor 45 of magnetizing mechanism 40, paper detector 80

It includes a ROM, etc., is connected to the host device 200 via the interface 101, and receives commands from the host device,
Alternatively, the printing apparatus is configured to be controllable based on the data.

The control circuit unit 100 controls the printing mechanism unit 90 based on a signal (command, data) from the host device, an instruction by a signal from the operation panel, a signal sent from the paper detector 80, and the like. It is configured to control the read head 30, the drive motor 63, and the like.

Next, a method of controlling the printing apparatus by the control circuit unit 100 will be described with reference to FIG. 6, and the operation of the printing apparatus 1 according to the present embodiment will be described with reference to FIGS.

In the printing apparatus 1 shown in FIG. 1, when the cleaning process is not selected on the operation panel 110 (step S101, NO), a normal printing process is performed (step S111).

The normal printing process includes a printing process, a magnetic reading process, and a composite process thereof, each of which is executed based on a command from the host device. In step S111, for example, when the magnetic reading process is designated, if the presence of the check paper 5 is detected by the paper leading edge sensor 81, if the magnetic circuit of the magnetizing mechanism is closed, the control circuit 100 According to the command, the magnetizing motor of the magnetizing mechanism unit 40 is driven to rotate the third yoke member 44 in the direction of arrow J shown in FIG. 3 to open the magnetic circuit and supply the magnetic field of the permanent magnet 41 to the check paper. Make it possible. If it is already open, it stands by. This state is stored in the RAM of the control circuit unit 100 so that the state of the magnetizing motor can be monitored.

At the same time, the head pressing section 32 of the magnetic reading head 30 is moved in the direction of arrow B and the driven roller 61 is moved in the direction of arrow G in response to a command from the control circuit section 100 (see FIG. 1). Then, in response to a command from the control circuit unit 100, the shielding unit 71a of the paper stopper 71 is rotated in the direction of arrow E to retract from the paper path 10, and then the drive motor 63 is started to move the check paper 5 in the transport direction A. send.

In this case, the MICR character 5 on the check sheet 5
When the “a” passes over the paper guide member 51 of the magnetization mechanism 40, the MICR character 5a on the check paper 5 is magnetized, and the magnetized MICR character 5a on the head base 31 of the magnetic reading head 30. Read.

Thereafter, the check paper 5 is transported by the transport rollers 93,
The print mechanism unit 90 transfers the check sheet 5 to, for example, the front side (MI side) of the check sheet 5 according to a command from the control circuit unit 100.
The MICR character 5 is printed on the side where the CR character 5a is printed.
The necessary items are printed based on the information read from a. Then, the printed check paper 5 is inserted into the paper discharge port 16.
To be discharged from

On the other hand, when the cleaning process is designated by the predetermined switch 110a of the operation panel 110 (step S101, YES), the magnetizing motor 45 of the magnetizing mechanism unit 40 is turned on by a command from the control circuit unit 100. Drive (step 102), the third yoke member 44 is moved to the position shown in FIG.
The magnetic circuit is closed by rotating the contact surface 42a of the first yoke member 42 and the contact portion 44a of the third yoke member 44 by rotating in the direction of arrow K shown in FIG.
3).

That is, the lines of magnetic force radiated from both pole portions of the permanent magnet 41 are looped through the first yoke member 42, the third yoke member 44, and the second yoke member 43, so that the magnetization mechanism 40 The magnetic circuit is closed at. As a result, the magnetic lines of force from the upper pole portion of the permanent magnet 41 are bent toward the first yoke member 42 without passing through the paper guide member 51. For this reason, the magnetic powder adsorbed on the paper guide member 51 is simply placed on the paper guide member 51 by, for example, the magnetization of the magnetic powder disappearing while the magnetic circuit of the magnetization mechanism 40 is opened. Put on the state.

In order to remove this magnetic powder, in the cleaning process of the present embodiment, for example, check paper 5
Cleaning sheet of almost the same shape as (cleaning member)
Is used. The cleaning sheet has a surface coated with an adhesive agent, and is configured so that small magnetic powders and the like can be easily captured and dust and dirt around the head and the like can be removed. The cleaning sheet is inserted into the paper insertion slot 13 to start conveying the cleaning sheet (step S104).

Then, in the cleaning process in step S105, the cleaning sheet is
The magnetic powder is removed from the paper guide member 25 by adsorbing the magnetic powder on the paper guide member 51 on the back side of the cleaning sheet when passing through the cleaning sheet.

When the cleaning sheet passes through the magnetic reading head 30, for example, the magnetic powder transferred from the paper guide member 51 and adhered to the magnetic reading head 30 is removed by the cleaning sheet.

This cleaning process is performed until the control circuit unit 100 recognizes the end of the cleaning (step S106, NO).

Here, for example, after the leading edge of the cleaning sheet is detected by the leading edge sensor 81, the control circuit unit 100 performs the cleaning based on the information that the leading edge sensor 81 does not detect the trailing edge of the cleaning sheet. An end command is sent to the magnetizing motor (step S10).
7, YES).

The magnetizing motor is driven based on the end command (step S107), and the third yoke member 44 is moved to the position shown in FIG.
To open the magnetic circuit of the magnetization mechanism 40 (step S108).

After that, the cleaning sheet is discharged from the paper discharge port 16 in the same manner as the check paper 5.

As described above, according to the present embodiment,
When the magnetic read head 30 is the MICR character 5a of the check paper 5
Is not read, since the magnetic circuit of the magnetizing mechanism 40 is closed, no magnetism can be generated in the paper path 10 of the printing apparatus 1. Thereby, it is possible to effectively prevent the magnetic powder from adhering to the paper guide member 51 around the permanent magnet 41 in the paper path 10.

As a result, according to the present embodiment, the transfer of the magnetic powder from the paper guide member 51 to the magnetic reading head 30 can be prevented, so that the MICR characters 5a can be read with high accuracy.

Further, according to the present embodiment, the magnetic circuit of the magnetizing mechanism 40 is closed when performing the cleaning process, so that even if the magnetic powder is adsorbed on the paper guide member 51, Since the magnetization disappears, the magnetic powder can be easily removed by the cleaning sheet.

Further, according to the present embodiment, not only the removal of the magnetic powder from the paper guide member 51 but also the
The removal of the magnetic powder of 0 can also be performed by only one conveyance of the cleaning sheet. In addition, since the magnetic powder of the head base 31 of the magnetic reading head 30 is attracted on the surface of the cleaning sheet opposite to the surface of the paper guide member 51 on which the magnetic powder is attracted, the head base 31 does not need to be damaged. There are advantages.

In the present embodiment, the magnetic circuit is opened and closed by a signal from the operation panel 110 to perform the cleaning process. However, the magnetic circuit is controlled by a command transmitted from the host via an interface. May be opened and closed to perform a cleaning process.

The present invention is not limited to the above embodiment, but can be variously modified.

For example, in the above-described embodiment, the third yoke member 44 of the magnetizing mechanism 40 is configured to be rotated by the magnetizing motor. However, in the embodiment shown in FIG. Is provided outside the main body case, and the third yoke member 44 can be opened and closed by manual operation of the lever 115.

Further, according to the present invention, it is possible to obtain a magnetic reading head cleaning method capable of effectively removing magnetic powder and the like from the magnetic reading head even if the magnetic powder and the like are transferred to the magnetic reading head.

Further, the cleaning operation can be set from the operation panel, so that the cleaning operation can be easily performed at any time.

Further, since the magnetic circuit can be opened and closed from the host device via the interface, there is an advantage that the cleaning can be performed by a command from the application of the host device.

In another embodiment of the present invention, since the magnetic circuit of the permanent magnet can be opened and closed by a lever installed outside the main body, the magnetic circuit must be closed when MICR characters are not read for a long time. Thereby, adhesion of magnetic powder and the like can be prevented.
