Abstract

PROBLEM TO BE SOLVED: To retain compactness and portability and make possible to print desired information to a desired printing medium by equipping with a scanning means to a printing medium, a print head which forms an image as the scanning means scans, and a print head control means which print stored information. SOLUTION: An opening 17 is provided on the left side face of an electronic calculator 1, a roller 19 as a scanning means, and an ink jet head 21 as a print head are arranged in parallel. The roller 19 has an encoder to detect the rotational position. The ink jet head 21 is connected to the head controller as the print head control means together with the encoder. The head controller controls the ink jet head 21 in accordance with the position of the roller 19 which is detected by the encoder and forms a print image. As a printer itself is a manual scanning type which does not have paper and a paper feeding mechanism, it is small and does not increase the size of the electronic calculator itself.
