Abstract
PURPOSE:To store a projection film optionally by providing a cutter which cuts a thermochromic film automatically by projection picture planes after printing on the thermochromic film unwound from a film roll. CONSTITUTION:An image sensor 13 reads an original 8 to be projected in order while the original platen 7 is moved as shown by an arrow L by driving a driving motor 4 after setting an original platen 7 where the original 8 is mounted at a readout position manually. The output of the sensor 13 is inputted to an image processing part 14 to make a shading correction, an MTF correction, etc., and perform A/D conversion, and the read signal is inputted to a head driving part 15 to drive a thermal head 2. At the same time, a platen 3 is rotated to move the thermochromic film 1 as shown by an arrow M and an image read by the sensor 13 is written on the film 1 by the thermal head 2 instantaneously. Thus, while the original image is written, the image is written on the film 1 and every time one projection plane is written, a cutter 16 which is powered on to generate heat fuses and cuts the film 1.
