PURPOSE:To prevent the wearing of a frictional member and a separator roller from occurring, to prevent an original from being fed at the time of mode switching, and to simplify the operation by constituting the titled reader so that a reading optical system engages with a rocking arm at the time of coming to a moving original reading position to open an original path and cause original separating members engage with each other. CONSTITUTION:The image sensor unit 11 is moved to a position P3 and locked there. At this time, the roller 111 provided on the end side of the unit 11 is abutted on the rocking arm 29, and pushes it 29 away against the pulling of a spring 292 in the direction of arrow F until the arm 29 comes in a position shown by the broken line at a specific angle. Accordingly, a sheet stopper 293 retreats from a slit 211 to enable the feeding of an original 20. At the same time a transmission member 295 also retreats, and the frictional member is pushed out by a spring 26 and engaged with the separator roller 22. when the originals 20 are present on an original placing tray 21, the originals 20 slides on the tray, comes in contact with the frictional member 23 and the separator roller 22 and stopps temporarily; then the originals 20 are fed out toward the position P3 by the separator roller 22 from the lowermost sheet first and sequentially one by one.
