PURPOSE:To enable printing-out of letters on ordinary paper in photo-process by utilizing color development of photosensitive liquid through light irradiation and liquid injection on paper in correspondence to letters. CONSTITUTION:Printing head 7 is moved by feed system 10 corresponding to synchronizing signal 9'', while pressure-wave generating device 1 is operated corresponding to letter signal 9' to make photosensitive liquid flow out from storing chamber 2 into pipe line 4. Applying rays from light source 6 to the photosensitive liquid so as to develop the color thereof, liquid injection is made on ordinary paper 11. Only the part of paper having received the jet of the developed liquid is recorded and, by repeating these operations several times, one letter is printed. Thus, the design for the system is easy and the printing of letters on ordinary paper is enabled. |
