Recording medium overturning mechanism and recording medium processing apparatus using the same

摘要

The present invention provides a recording medium overturning mechanism, comprising: a bracket (100); an entry (50) and an exit (60), arranged in the bracket (100); a first channel (10), communicating the entry (50) with the exit (60) to convey a recording medium which does not need to be overturned; a second channel (20), communicating with the entry (50) to convey a recording medium which needs to be overturned; a third channel (30), communicating with the exit (60) and the second channel (20) to convey the overturned recording medium, wherein the first channel (10), the second channel (20) and the third channel (30) are basically arranged in an inverted triangle and joined with each other; a channel switching mechanism (40), arranged on the bracket (100) and located at a joining area between the first channel (10) and the second channel (20); and an overturning roller (70), arranged on the bracket (100) and located at a joining area between the second channel (20) and the third channel (30), the overturning roller (70) is driven by a motor (M), and the overturning roller (70) firstly rotates in a first direction to convey the recording medium away from the second channel (20), and then rotates in a direction opposite to the first direction to send the recording medium into the third channel (30). The present invention is simple in structure, small in volume and low in cost.
