- a housing,
- an optical system,
- an automatic document feeder with a document supplying section at one end in the upper part of said housing,
- an automatic document winding device at the other end of said housing with a drum for wrapping a document therearound,
- a document size sensor for detecting the size of a document supplied from said document supplying section relative to the size of said drum, and
- selecting means capable of automatically selecting on the basis of document size detected by said document size sensor between a first mode of operation wherein a document is transported by said automatic document feeder and said optical system is moved to scan said document and a second mode of operation wherein a document is transported by said automatic document winding device and wherein said optical system remains fixed and said drum is rotated to scan said document.
- 2. The image formation apparatus of claim 1 wherein said automatic document feeder is openable with respect to said housing and said image formation apparatus further comprises an open-close sensor for detecting whether said automatic document feeder is opened.
- 3. The image formation apparatus of claim 2 wherein said selecting means are adapted to select said first mode of operation if said open-close sensor detects that said automatic document feeder has been opened.
- 4.

- 5. The image formation apparatus of claim 2 wherein said selecting means are adapted to select said second mode of operation if said open-close sensor detects that said automatic document feeder has not been opened and said document size sensor detects that document size to be smaller than the circumference of said drum.
- 6. The image formation apparatus of claim 1 wherein said document size sensor serves to determine whether said document supplied from said document supplying section can be wrapped around said drum without overlapping itself.
