Claims

[Scope of utility model registration request]

A housing, a printer head disposed within the housing for printing on external recording paper, a printer control means for driving the printer head as the housing moves in contact with the recording paper; an ink ribbon interposed between the printer head and the recording paper; an ink ribbon moving means for moving the ink ribbon as the housing moves; and data to be printed by the printer head. a print data detection means for detecting the presence or absence of data to be printed; and an ink ribbon movement prevention means for preventing the movement of the ink ribbon by the ink ribbon movement means when the print data detection means detects that there is no data to be printed. A small printing device characterized by:
