Abstract

PURPOSE:To simplify a mechanism extremely without using a motor, etc. by a method wherein an external heat source is used, and a paper feed roller is turned by the positional relationship of temperature sensing magnets, magnetizing facilitating axial direction thereof changes due to temperature, and permanent magnets. CONSTITUTION:The permanent magnets 2a, 2b are mounted to the both ends of a paper feed roller 1 of a thermal printer, and a plurality of temperature sensign magnets 3a, 3b are disposed around the outsides at regular intervals in response to the width of paper feed. The temperature sensing magnets 4a, 4b are installed at the outsides of the roller 1, and the permanent magnets 5a, 5b and 6a, 6b are mounted to the upper portions and the side portions. The permanent magnets 8a, 8b are disposed to a thermal head, and heating parts are mounted to the lower portions in elongated shapes. Thus, the temperature sensing magnets are heated, the magnetizing directions are changed, and the temperature sensing magnets are operated with the attraction of the permanent magnets. consequently, the roller 1 can be driven by step, and the mechanism can largely be simplified.
