Claim:
1. A paper receiving device comprising: a paper receiving member that receives a paper sheet; a first detector that detects whether or not a size of the paper sheet received by the paper receiving member is greater than a first size; a second detector that detects whether or not the size of the paper sheet received by the paper receiving member is smaller than a second size that is smaller than the first size; and an open-state detector that detects that the paper receiving device is opened when the first detector detects that the size of the paper sheet is greater than the first size and the second detector detects that the size of the paper sheet is smaller than the second size, wherein the open-state detector detects that the paper receiving device is opened by changing a detection result of the second detector in response to an opening-closing movement of the paper receiving device, the opening-closing movement is a movement in which the paper receiving device is opened or closed by being rotated around a fulcrum, and the second detector includes an actuator and a sensor, and the open-state detector is configured such that when the paper receiving device is opened or closed, the actuator is displaced owing to a weight of the actuator so that a detection result of the sensor is changed.
