Title: Tension arm mechanism
Inventor: KIJIMA TAKUMI
IPC: G11B15/43
Filed: 1990-01-16
Abstract: PURPOSE:To minimize a load to turn and fix a tension arm at an unloading position by using a superelastic spring as an energizing material to energize the tension arm in a prescribed direction. CONSTITUTION:The superelastic spring made of superelastic alloy is used as the energizing material 4 which energizes the tension arm 3 and supplies prescribed tension to a magnetic tape 1 as a result. Therefore, the desired energizing force can be generated in a range where the magnetic tape 1 comes into contact with a tension pole 2 in a loading state and the tension arm 3 performs tape tension control, and since superelasticity is generated when the tension arm is located at the unloading position which requires the high stretch of the spring, the energizing force is scarcely increased. Thereby, it is possible to reduce the load at the unloading position.

Abstract: PROBLEM TO BE SOLVED: To easily perform a jam processing even when paper jamming occurs at the time of a switchback operation by performing the switchback operation by reversing the advancing direction of one end of transferred paper after the one end is temporarily projected on the upper surface of an image forming part. SOLUTION: When a carrier unit 4 for copying double-sides is used, an image is formed on one surface side of paper P in process that paper P is carried by successive way of an image making part 16 and a fixing roller 17. Paper P is successively discharged by a discharge roller 31 from the tip part to the outside of a paper discharge port 18. The discharge roller 31 stops the revolution in a state that the roller 31 holds the rear end part of paper P. Continuously, the discharge roller 31 starts revolution which is reverse to the previous revolution. Paper P is sucked into the discharge port 18 again, is further guided to a paper discharge port 19 and is discharged by a discharge roller 32. By this switchback operation, the front and rear surfaces of paper P are reversed for the advancing direction.  Thus, even if a paper jamming is generated in process of the operation, a jam processing can be easily performed.
