A conveying device includes a controller configured to control conveyance of a workpiece. The controller includes a first calculator configured to calculate a first roll estimated radius of a first roll varied as a first support shaft rotates. The controller further includes a second calculator configured to calculate a second roll estimated radius of a second roll varied as a second support shaft rotates. The controller also includes a first support shaft drive controller configured to cause a first support shaft driving motor to rotary drive at a first angular velocity according to the first roll estimated radius. The controller further includes a second support shaft drive controller configured to cause a second support shaft driving motor to rotary drive at a second angular velocity according to the second roll estimated radius.

Conveying device and image forming device

An operation mode control system includes an obtainment processing portion and a shift processing portion. The obtainment processing portion obtains sound volume data indicating a sound volume level of ambient sound around an image forming apparatus that is operating in a first mode in which all or a part of functions relating to image formation is restricted. The shift processing portion shifts, when a count of a number of times it is determined during a preset specific time period that the sound volume level is a first reference level or more, is a preset specific count or more, the image forming apparatus into a second mode in which it is possible for image formation to begin.
