Abstract

PURPOSE:To reduce the time required for picture formation, by enabling the readin even for the reciprocation of the readin means, in the picture forming unit scanned with optical readin. CONSTITUTION:At the side of the optical readin section 4, the guide member 9 inserted to the guide rail 3 and the indication member 13 for position are provided. The detection members 19-22 are present at the forward path where the rod shape protrusion 16 of the indication member 13 passes and the readin start signal is output through the passage of the protrusion 16. The indication member 13 is provided with the flat plate protrusion 17, and when the protrusion 17 passes through the second initial position detection member 30, the stop signal is output. In the readin of picture at the next return, a signal is fed to the laser emission circuit in the opposite order to the forward to make agreement the direction of picture with the copy at forward.
