Abstract:
1. A sheet bundle conveying apparatus that conveys a paper sheet bundle in which one or more paper sheets are stacked, along a conveying path, comprising: a carrier including one or more push-out plates that come into contact with the paper sheet bundle to push the paper sheet bundle, the carrier being moved along the conveying path; an impeller that suppresses the paper sheet included in the paper sheet bundle from entering a gap existing between a lower wall or an upper wall of the conveying path and one of the push-out plates, the lower wall or the upper wall of the conveying path contacted with the paper sheet bundle pushed by the carrier; and a power source that rotates the impeller, wherein the impeller includes a plurality of elastic members each of which has an elastic force and which protrude along a radial direction and are provided at a given interval in a circumferential direction; and the impeller suppresses, when the carrier is stopped, the paper sheet from entering the gap, by means of the impeller with the elastic members being in contact with the lower wall or the upper wall of the conveying path, and the impeller suppresses, when the carrier is moved, the paper sheets from entering the gap, by causing the power source to rotate the impeller and applying a push-out force to the paper sheet via the elastic members coming into contact with portions of the paper sheet, the portions each having entered the gap.
