ABSTRACT:
The improved package of thermal recording sheets of the invention is wrapped as a stack which contains at least one maintenance sheet in addition to the thermal recording sheets. The improved thermal image recording apparatus of the invention uses the improved package, detects directly or indirectly that the next sheet is the maintenance sheet by a detection sensor and allows the first or detected maintenance sheet to be carried to a recording section by a transport device and a treatment associated with the maintenance sheet to perform in the recording section by a control device. Other improved apparatus of the invention is provided with a maintenance sheet magazine for accommodating maintenance sheets and allow the treatment to perform at the recording section in the same manner. Therefore, the improved package and apparatus permit the thermal head to be cleaned periodically in an automatic fashion. As a result, the thermal head can be maintained in a sufficiently good condition to ensure consistent thermal recording to produce high-quality images.
