  • Tension applying device, sheet conveyance device, and image forming apparatus
    Patent number: 11577532
    Abstract: A tension applying device is attached to a sheet conveyance device. The sheet conveyance device includes a feeding roller for feeding a continuous-form sheet and a winding roller for winding the continuous-form sheet fed from the feeding roller. The tension applying device applies tension to the continuous-form sheet between the feeding roller and the winding roller. The tension applying device includes a guide rail, a slider, a tension bar, and an angle adjustment mechanism. The guide rail is inclined downward toward a continuous-form sheet. The slider slides along the guide rail. The tension bar is supported by the slider and brought into pressure contact with the continuous-form sheet by weight of the slider. The angle adjustment mechanism adjusts an inclination angle of the guide rail with respect to a horizontal direction.
