2. Description of the Related Art In a conventional automatic transaction apparatus, when a deposit transaction, a withdrawal transaction, or the like is performed, the transaction contents are printed out as a transaction record in a journal. A thermal printer is used as a print unit for printing transaction records on such a journal, and is composed of a thermal head (print head) and thermal paper printed out by the thermal head. Transaction records to this journal had to be made reliably.

In such a thermal printer using thermal paper, a power supply is required to check whether printing can be performed correctly, for example, whether the loaded paper is really thermal paper or the coloring surface is in contact with the thermal head. At the time of self-diagnosis or the like after input, a color development check is performed using a reflection type optical sensor (hereinafter, reflection sensor).

Then, the magnetic card is taken into the magnetic card reader 31 and the account information such as the bank number, the branch number, and the account number recorded in the magnetic stripe portion is read, and the image reader 46 reads the emboss area of the magnetic card. An image is captured. The account information is checked by the main control unit 21 and when it is determined that the magnetic card is not correct, the main control unit 21
Performs error handling. When determining that the magnetic card is correct, the main control unit 21 instructs the journal printer 33 to perform printing. Thereby, the journal printer 33
First prints this image on the journal paper 64, and then prints account information such as transaction date and time, transaction item, and account number on the journal paper 64.

The main control section 21 is provided with the magnetic card reader 3.
Create a transaction request message consisting of the account information read in step 1,
The created transaction request message is transmitted by the transmission control unit 20 to the host computer 24. At the same time as the above processing, the main control unit 21 causes the liquid crystal display device 6 to display "Please press your personal identification number", and also displays a numeric keypad and a correction key.

Next, the user enters a password by pressing down the portion on which the numeric keypad is displayed in accordance with the guidance. Also, while the personal identification number is being input by the user, the main control unit 21 receives the balance content electronic message as the transaction response electronic message including the personal identification number from the host computer 24 via the transmission control unit 23 (reception). Do).

Then, the main control section 21 compares the personal identification number from the host computer 24 with the inputted personal identification number. If the collation results match, the main control unit 21 causes the liquid crystal display device 6 to display "balance is in yen".
When the confirmation key is input by the user, the main controller 21 causes the card slot 9 to eject the magnetic card. Thus, the customer receives the magnetic card and ends the transaction.

Further, the main control section 21 outputs to the journal printer 33 an instruction to print information such as transaction establishment and transaction failure based on a transaction response message from the host computer 24. As a result, the journal printer 33 prints information such as transaction completion and transaction failure on the journal paper 64.

As described above, printing (recording) by the journal printer 33 is a small transaction, and is important as an automatic transaction apparatus. As described above, at the time of self-diagnosis after the power is turned on, three check patterns a, b, and c are printed on the journal paper 64 as check marks, and the check patterns a,
The thermal head 61 compares the voltage values from the reflection sensors 68 and 69 at points a, b and c where b and c are printed and at point d where no check pattern is printed.
The drive IC blocks 61a, 61b, 61c, and 61d determine whether or not normal printing is performed, and detect a failure or abnormality for each of a plurality of drive IC blocks that constitute a thermal head for journal printing. It was done.

Thus, at the time of self-diagnosis after power-on,
It is possible to accurately confirm whether journal printing can be normally performed. As a result, it is possible to prevent the printing process from continuing without being able to recognize the occurrence of the printing failure.

That is, it is possible to detect a printing failure due to poor contact between the thermal head and the paper due to a partial contact of the thermal head or adhesion of dust and the like, thereby preventing fatal incomplete printing as a journal print printer.

By arranging a reflection sensor for detecting an abnormality at a position opposite to the center of two driving IC blocks, the number of the reflection sensors is divided by the number of driving IC blocks by 2 (the remainder is added. ).

In the above embodiment, the output voltage value from the reflection sensor is converted into a digital value by the A / D converter and checked. However, the check may be performed by using a comparator.
