Abstract
A stamp device is capable of selecting a current supply time for use by a thermal head in accordance with an ink temperature detected by a temperature sensor so as to control the size of perforations to be formed on a heat sensitive stencil paper by the thermal head. Therefore, the stamp device can form uniform images even when there is a variation in the viscosity of ink caused by changes in the evironmental temperature of the stamp device.
