Abstract
A cam 37 is rotated in an arrow F direction. This causes sheet conveyance rollers 10a, 10b and guide elements 33, 34 to rotate on a lower conveyance shaft 27 and an upper conveyance shaft 30, respectively, so that they are separated from a drive roller 12. Thus, a spur plate 21 faces the upward stream end with respect to the recording sheet conveyance direction and opens in synchronism with the sheet conveyance rollers 10a and 10b, etc. Accordingly, it is possible to readily remove a recording sheet subjected to the jam.
