IMAGE FORMING APPARATUS, METHOD OF CONTROLLING TENSION OF RECORDING MEDIUM

摘要

An image forming apparatus includes a first roller and a second roller on which a recording medium is stretched; a head which performs image forming on the recording medium in an image forming region between the first roller and the second roller; an opening-shutting door which is provided in an external member; an opening-shutting regulation unit which regulates an opening operation of the opening-shutting door; and a control unit which transports the recording medium while applying a tension to the recording medium in the image forming region by controlling rotations of the first and second rollers, and regulates the opening operation of the opening-shutting door by the opening-shutting regulation unit while the head is performing the image forming, in which the control unit releases a regulation of the opening operation of the opening-shutting door by the opening-shutting regulation unit after performing a preparation operation for releasing the regulation which stops the recording medium in a state in which the tension is applied to the recording medium in the image forming region by controlling the rotations of the first and second rollers.

主权项

1. An image forming apparatus comprising:
a first roller; a second roller on which a recording medium is stretched between the first roller and the second roller; a head which performs image forming on the recording medium in an image forming region between the first roller and the second roller; two rotational shafts with which the recording medium is supported in a roll shaped; and a control unit which transports the recording medium while applying a tension to the recording medium in the image forming region by controlling rotations of the first and second rollers, wherein the recording medium is transported using a roll to roll method from one of the two rotational shafts to the other of the two rotational shafts, and the recording medium is stopped in the image forming region in a state in which tension is applied thereto while the recording medium supported by either of the two rotational shafts is exchanged.
