PERFECTING-PRINTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a perfecting-printing device in which operability of jamming release is good. SOLUTION: The perfecting-printing device is equipped with a sheet cassette 2 capable of housing sheets 3 from the operation face side, with a first conveyance path 5 which takes out the sheet 3 from the sheet cassette 2 and conveys it to a process unit 4 and a transfer part 13 and furthermore a fixing device 14 and with a sheet reversing mechanism 6 having a conveyance direction changeover plate 11. The conveyance direction changeover plate 11 reverses the conveyance direction of the form 3 printed on the front surface through the process unit 4 and the transfer part 13 and furthermore the fixing device 14 and is positioned on the downstream side of the first conveyance path 5 and reverses the conveyance direction just before conducting the sheet 3 conveyed from the first conveyance path 5 to a delivery receiver 10 and conducts the sheet 3 to a second conveyance path 7. Furthermore, the both sides-printing device is equipped with the second conveyance path 7 which conveys the sheet 3 from the sheet reversing mechanism 6 to the upstream side of the first conveyance path 5 and with a sheet conveying mechanism 9. The sheet conveying mechanism 9 is incorporated with the first conveyance path 5, the sheet reversing mechanism 6 and the second conveyance path 7 to take out a jamming sheet from the operation face side and is turned around the prescribed rotation shaft 8 to the operation face side.
