ABSTRACT:
A picture image input device having the capabilities of a sheet fed scanner with respect to sheet-type original media and realizing the convenience of a hand scanner with respect to original media such as books and the like. The picture image input device includes a light source that emits light for reading an original medium, an image sensor, a projection optical system that composes an image of the original medium on the image sensor, a driving unit that moves the original medium relative to the image sensor and a folding joint unit that changes the usage state between one of an open state and a folded state. In the open state the picture image input device functions as a hand scanner. In the closed state the picture image input device functions as a sheet fed scanner. The reading position of the original medium is the boundary between a reading unit and a driving unit of the picture image input device in the folded state.
