<p>PURPOSE:To provide a sheet carrier device capable of stably carrying an endless sheet in the forward direction and in the backward direction without slipping and without increasing driving torque. CONSTITUTION:An image forming device is furnished with a sheet carrier device (sheet unit) S, and the sheet unit S has a recording sheet (endless sheet) 10, a means to give tensile force to the recording sheet 10, a recording roller (driving roller) 20 to make contact with the recording sheet 10, a power source and a drive transmission means to transmit power from the power source to the recording roller 20. The means to give tensile force to the recording sheet 10 is constituted of a member to give pressure force or tensile force to the recording roller 20. Consequently, it is possible to smoothly drive the recording roller 20 while giving proper tensile force to the recording sheet 10, and accordingly, it is possible to stably carry the recording sheet 10 in the forward direction and in the backward direction without slipping and without increasing driving torque.</p> |
