Belt conveyance device with a meandering correction part shifting one end of a tension roller and an adjustment part shifting the other end

A belt conveyance device comprising:

• a plurality of rollers disposed at intervals from each other and rotating around axes;
• a belt disposed around the plurality of rollers and traveling;
• a meandering correction part which shifts one end portion in an axial direction of a tension roller included in the plurality of rollers in a radial direction within a predetermined range to correct a meandering of the belt;
• an adjustment part which shifts the other end portion in the axial direction of the tension roller, which is an opposite end portion to the one end portion, in the radial direction;
• and
• a control part controlling the plurality of rollers, the belt and the meandering correction part, wherein
• the one end portion of the tension roller is automatically shifted in the radial direction by the meandering correction part controlled by the control part, and
• the other end portion of the tension roller is shifted in the radial direction by the adjustment part operated manually.
