In the figure, reference numeral 1 denotes an image reading unit that reads the entire image including the embossed characters on the card 2, and the image reading unit 1 is connected to a light source 3. CCD sensor 4° A/D converter 5. and a drive control section 6 that drives these.

Reference numeral 7 denotes an image processing unit that processes the image of the read card, and the image processing unit 7 includes a first image memory 8 that removably stores the read image data, and detects the characteristics of the card from the read image data. Card feature detection section 9.
Density adjustment setting section 10 in which density adjustment values are set in advance
．． A density conversion processing unit 11 that performs density conversion processing on data of one image read according to the density adjustment value according to the characteristics of the card 2 and the density adjustment value set in the density adjustment setting unit 10. The image data created by the density conversion processing section 11 is
A binarization processing unit 12 that performs digitization processing, and a second image memory 13 that retrievably stores image data created by the binarization processing unit 12. It is composed of an interface section 15 that sends and receives signals to and from the printing section 14.

16 is a main control section that controls the operation of the entire device.

FIG. 2 is a flowchart showing the operation of this embodiment,
The operation of this embodiment having the above configuration will be explained below with reference to the figure.

First, since the density of the image printed on the card 2 differs depending on the printing medium, please enter the density adjustment setting section in advance so that the density matches the type of medium or the desired density of the device adjuster. Set the adjustment value.

Next, when the card 2 used at a bank etc. that can be handled by the automatic transaction device is inserted into the automatic transaction device (S 1 )
, the card 2 is conveyed below the CCD sensor 4 of the image reading section 1 (S2).

Next, when it is detected that the card has been conveyed below the CCD sensor 4, the light source 3 emits infrared light from above the card 2,
While the card 2 is being conveyed, the CCD sensor 4 reads changes in reflected light from the embossed characters and background pattern portions on the surface of the card 2 (S3). At this time, the data of the reflected light is converted into a digital signal (multi-valued data) by the A/D converter 5 and stored in the first image memory 8 as image data (S4).

At the same time, the card feature detection unit 9 settles all the data and detects the features of the card 2 based on the settlement results (
S5).

For example: - Digital value for reflective light mill FF Settlement result → large - Digital value for reflective light field 00 Settlement result → small From this settlement result (Σ), Σ large Reflected light is mostly white → whitish card Σ small Reflection The light is mostly black → a darkish card Σ medium The reflected light is evenly white/black → a grayish card is detected.

The image data of the card 2 converted into multivalued data stored in the first image memory 8 is subjected to density conversion according to the adjustment value set in the density adjustment setting section 10 and the feature detected by the card feature detection section 9. (S6).

For example, the level of the multivalued data of each pixel constituting the image may be made darker for the darker setting in the density adjustment setting section 10,
The multi-valued data of each pixel that makes up the image is made whiter than the lighter setting. In normal settings, there is no density conversion.

In addition to this adjustment, before the binarization process, density conversion of the multi-value data level is synthesized so that the optimum binarization is performed according to the level of the multi-value data at the time of reading.

The density-converted image data of the card 2 is binarized and stored in the second image memory 13 (S7).

The binarized image data of the card 2 stored in the second image memory 13 is transferred to the printing unit 14 via the interface unit 15 (S8), and is printed out onto a printing medium (S9).
