Abstract
A scanning-printing integrated apparatus comprises a scanning passage (1), a printing passage (3) communicated with the scanning passage (1), a transitional passage (2) providing printing medium to the printing passage (3), a first driving mechanism for driving the paper conveying roller (12) of the scanning passage (1) and the paper conveying roller (312) of the printing passage (3), and a second driving mechanism for driving the paper conveying roller (21) of the transitional passage (2) and the paper conveying roller (312) of the printing passage (3). The two ends of the paper conveying roller (312) of the printing passage (3) are respectively transmission-connected to the first driving mechanism and the second driving mechanism via one-way bearings (71, 72). By providing one-way bearings at the two ends of the paper conveying roller of the printing passage, the first driving mechanism and the second driving mechanism work independently without interfering with each other, so that the two driving mechanisms drive the manuscript or printing paper to be freely conveyed in the scanning passage, the printing passage and the transitional passage without increasing loads.
