International ClassB41J 003/36Foreign Application Priority Data1987-04-17 JPAbstractA manually operable sweeping-type compact printer apparatus has an input section, a display section, an electric circuit section, and a printer unit. All these components are incorporated in a housing. The printer unit includes a print head, rollers, an encoder, and a ribbon take-up device--all attached to a chassis which is fixed within the housing. When an operator holds the printer apparatus and moves it across a recording medium, while keeping the rollers and the print head in contact with the medium, the print head prints data on the recording medium. | |
