Title: Perfecting printer for cutform
Inventor: ANDO HARUYUKI
IPC: B41J3/60
Filed: 1990-08-20
Abstract: PURPOSE:To achieve perfecting of a cutform by receiving a cutform printed on one face through a cutform printer, turning the cutform by 180 deg. and returning the turned cutform to the cutform printer under a state for printing on the rear surface and then turning over the cutform immediately in front of a printing mechanism. CONSTITUTION:A cutform is printed on the surface at a print mechanism section and carried through a guide 11 to a converting unit 8 thence through a carrying roller 5 to a sensor 9. When the sensor 9 detects the leading end of the cutform, a solenoid 1 functions to lower a plunger 101 so as to lift a drive roller 3 which is thereby separated from the carrying roller 5. A conversion motor 6 is then operated based on the operational information of the solenoid 1 and the converting unit 8 is rotated by 180 deg. by means of a converting belt 7 and a rotary roller 10 thus turning over the cutform. The solenoid 1 is then operated again to return the drive roller 3 and the cutform is carried by means of the carrying roller 5, a slit 81 and the guide 11 to the print mechanism section thus bringing rear surface printing state.
