Abstract
A device for adjusting tension applied to a photoreceptor belt in a printing apparatus. The tension adjusting device includes a control mechanism for controlling the operation of a driving motor such that a tension adjusting mechanism operates in three modes including a normal print mode where the tension is applied to the photoreceptor belt for normal printing, a loosened tension mode where the tension to the photoreceptor belt is loosened due to suspension of the printing operation, and a belt replace mode where the tension to the photoreceptor belt is released so that the photoreceptor belt can be replaced. For mode switching, the control mechanism controls the driving motor according to the position of the tension adjusting mechanism, detected by a sensing mechanism, or by detecting the load applied to the driving motor. Therefore, during suspension of the printing operation, the mode can be switched into the loosened tension mode, so that the tension to the photoreceptor belt can be released without damage to the photoreceptor belt. As a result, a partial stiffening and folding of the photoreceptor belt at the bent portion thereof can be prevented.
