Patent ID: 8720887

Claim:
A conveying mechanism for conveying a sheet, comprising: a first conveying element including an upstream end on which a feeding assembly for feeding the sheet is formed; a second conveying element configured to confront the first conveying element; the second conveying element at least partially defining a conveying path for guiding the sheet in cooperation with the first conveying element has a turning element including a first end and a second end which are aligned along a sheet feeding direction, and a displacement element coupled to the turning element, a positioning mechanism configured to position the displacement element with respect to the first conveying element when the turning element is located in the first position, wherein the first end is held pivotally near the first conveying element, the second end is coupled pivotally to the displacement element, the displacement element extends along the first conveying element and defines the conveying path between the displacement element and the first conveying element when the turning element is located in a first position where the turning element extends along the first conveying element, and the displacement element translates away from the first conveying element to form a corner with the turning element when the turning element turns from the first position to a second position where the second end of the turning element moves away from the first conveying element, wherein the positioning mechanism includes: (i) an engaging hole defined in the first conveying element, (ii) a retractable engaging piece attached to the displacement element and configured to engage with the engaging hole, and (iii) a biasing member configured to bias the engaging piece so as to protrude the engaging piece with respect to the displacement element.
