DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light source switching device for reading an image of a passbook printer and a method thereof.

[0002]

2. Description of the Related Art FIG. 3 is a flowchart showing an example of a conventional light source switching method for image reading of a passbook printer. An example of a conventional light source switching method for image reading of a passbook printer will be described with reference to FIG.

First, the operator notifies the host device of the start of image processing (step 31). The host device issues a clamp command (step 32) and an image read command (step 33) to the passbook printer in order to read the image of the medium. At this time, the default color red is specified as the light source of the image.
The passbook printer enters the medium insertion monitoring state by the clamp command (step 32), and prepares to turn on the image light source in red by the image read command (step 33).

Next, the operator notifies the host device of a request to switch the light source from red to green (step 3).
4). The higher-level device issues a cancel command to the passbook printer in order to cancel the process of reading the image in red once (step 35). The passbook printer cancels the medium insertion monitoring by this cancel command (step 35) and cancels the preparation for turning on the image light source in red (steps 36, 37 and 3).
8).

[0005] Then, the host device issues a clamp command (step 39) and an image read command (step 40) to the passbook printer again in order to read the image of the medium. At this time, green is designated as the image light source. The passbook printer executes the preparation for turning on the image light source in green by the clamp command (step 40). Thereafter, the operator inserts the medium into the passbook printer (step 41), and conveys the medium while reading the image with the green light source (steps 41, 42 and 43).

[0006]

The conventional light source switching method for reading an image of a passbook printer is disclosed in Japanese Patent Application Laid-Open No. H11-27300, when the passbook printer is preparing for light emission by an operator's instruction to emit light with a red light source from the host device. When there is an operator change instruction to emit light with the green light source, the host device issues an instruction to cancel the emission of the red light source and the insertion of the medium to the passbook printer, and issues an instruction to emit the light of the green light source and the medium again. I do. Therefore, the image reading process using the light source color (here, red) that has been set once must be canceled and the image reading process using the new light source color (here, green) must be started again. It gets complicated.

An object of the present invention is to switch the light emission of a light source from one light source to another light source instead of canceling the image reading process using the light source color once set and starting the image reading process again using the new light source color. Accordingly, an object of the present invention is to provide a light source switching device for image reading of a passbook printer and a method thereof, in which processing on the passbook printer is simplified.

[0008]

A light source switching unit for image reading of a passbook printer according to the present invention is a light source switching unit for switching light emission of two light sources having different emission colors in accordance with an instruction from a host device via an interface unit. An image reading unit for reading characters or images of a passbook or a voucher using the light source; and a printing unit for performing suction / print / discharge processing of the passbook or the voucher.

Further, in the light source switching device for image reading of a passbook printer according to the present invention, the passbook printer prepares for light emission in response to an operator instruction from the higher-level device through the interface unit to emit light with the first light source. When there is an operator change instruction from the higher-level device via the interface unit to emit light with the second light source, a command to cancel the emission of the first light source and the insertion of the medium from the higher-level device is issued. Instead of performing, the light source switching unit is configured to perform switching of light emission of the light source from the first light source to the second light source.

Further, the light source switching method for image reading of a passbook printer according to the present invention is characterized in that when the passbook printer is preparing for light emission by an operator's instruction from the host device to emit light with the first light source, When there is an operator change instruction to emit light from the second light source, instead of executing a command from the higher-level device to stop emitting the first light source and insert the medium, the light emission of the light source is performed from the first light source. Switching to the second light source is performed.

[0011]

Next, embodiments of the present invention will be described in detail with reference to the drawings.

The image reading light source switching device of the passbook printer according to this embodiment is provided with two light sources 6 and 7 having different emission colors, for example, red or green, in response to an instruction from the host device 13 via the interface unit 4. The reading unit 2 includes a light source switching unit 5 that switches light emission, an image reading unit 8 that reads characters or images of a passbook or a slip by the light sources 6 and 7, a suction processing unit 9 that suctions a passbook or a slip, and print processing. The printing unit 3 includes a print processing unit 10 and a discharge processing unit 11 that performs a discharge process.

The light source switching unit 5 switches the interface unit 4 when the passbook printer 1 is preparing for light emission in response to an operator instruction from the host device 13 via the interface unit 4 to emit light with the red light source 6, for example. Via the host device 13
For example, when there is an operator change instruction to emit light from the green light source, a command to cancel the light emission of the red light source 6 and the insertion of the medium from the host device 13 is executed, and a command to emit the light of the green light source 7 and insert the medium is executed again. instead of,
Only switching the light emission of the light source from the red light source to the green light source is executed.

FIG. 2 is a flow chart showing the flow of processing in this embodiment. The operation of this embodiment will be described with reference to FIG. 2 and FIG.

First, the operator notifies the host device 13 of the start of image processing (step 21). Host device 1
3 issues a clamp command and an image read command to the passbook printer 1 in order to read the image of the medium (steps 22 and 23). On this occasion,
Specifies the default color red as the light source for the image. The passbook printer 1 enters the medium insertion monitoring state by the clamp command (step 22), and prepares to turn on the light source of the image in red by the image read command (step 23).

Next, the operator notifies the host device 13 of a request to switch the light source from red to green (step 2).
4). The host device 13 issues a light source switching command to the passbook printer 1 to switch the image reading light source from red to green (step 25). The passbook printer 1 executes the preparation for turning on the light source for image reading in green by the light source switching command (step 25).

Thereafter, when the operator inserts the medium into the passbook printer 1 (step 26), the light source is green,
The medium is transported while the image is being read (steps 27 and 28).

[0018]

As described above, according to the present invention,
When the passbook printer is preparing for light emission by an operator instruction to emit light from the first light source from the host device, and when there is an operator change instruction to emit light from the second light source from the host device, the passbook printer receives the instruction from the host device. By performing the switching of the light emission of the light source from the first light source to the second light source instead of executing the instruction to cancel the light emission of the first light source and the insertion of the medium, the processing on the passbook printer side is simplified.
