PURPOSE:To provide a printing mechanism adapted to improve the reliability of print recording by effectively loading thermosensitive sheets at the setting direction of a thermosensitive color developing surface of the sheet to a print heat generator side. CONSTITUTION:A main controller 17 instructs a first print input of irregular random number which is different at each time of loading to a printing mechanism 2 at the time of loading thermosensitive sheets 5. A printing unit 7 prints it on the sheet 5, which is recognized by the person in charge by his visual observation. When it coincides with data by second print input by an amount input key, its transaction is conducted. When it does not coincide with the data, it is judged that the sheet 5 is erroneously loaded. |
