摘要： A scanner-equipped apparatus includes a combination of a base unit such as a printer unit, personal computer or word processor incorporating a printer unit and a scanner unit. The printer unit and the scanner unit can operate as automatic sheet feeder type apparatus, respectively. The scanner unit can be used as a handy scanner in the state detached from the base unit. The basic unit and the scanner unit are disposed substantially in upstanding posture in parallel with each other, wherein the scanner unit is removably combined with the base unit so that the scanner unit can be used as the handy scanner. A sheet transporting path for the scanner is formed between confronting surfaces of the base unit and the scanner unit. The sheet feeding mechanism for the scanner unit is so implemented as to be used intact as a driving mechanism for the handy scanner. The scanner-equipped apparatus can be realized inexpensively in a simplified mechanical structure while ensuring enhanced manipulatability.
