<p>PROBLEM TO BE SOLVED: To improve operability of jam treatment by composing a reconveying means of a first unit and a second unit, and constituting in such a way that the second unit is spaced from the first unit interlockingly with the fitting/ removal of the other unit. SOLUTION: When an intermediate tray 19 is pulled out onto the front side of a device body at the time of jam treatment, a conveyor belt frame body 22 is rotated downward around a supporting shaft, and a pressure means provided at the intermediate tray 19 comes off a lower unit 18b so as to release pressing of the unit 18b. The lower unit 18b is therefore rotated downward around the supporting shaft and moved into a position spaced from an upper unit 18a. At this time, the lower unit 18b is in a state of being supported only by a lifting spring 21. The force of the lifting spring 21 lifting the lower unit 18b is to be the force required to support the lower unit 18b and can be set small. Accordingly, in the case of a jam being generated in a double-side conveying bus 18, the lower unit 18b is pressed downward with small force to remove a sheet.</p> |
