Claims

[Claims for Utility Model Registration] A contact piece against which the leading edge of the paper being transported in the paper path comes into contact;
a swing arm consisting of a detection piece that swings integrally with the contact piece; a swing arm configured to position the contact piece within the paper path when the paper does not contact the contact piece; urging means for rotationally biasing the contact piece toward the upstream side of the paper path; and a detection means installed at a position close to the detection piece when the contact piece is located in the passage, and detecting the proximity of the detection piece. and a paper detecting device provided with a regulating means for regulating rotation of the swinging arm urged by the urging means by contact with the arm when the paper does not contact the contact piece. 2. A paper detection device, characterized in that an elastic material is provided at a portion of the regulating means that the swinging arm contacts or a location of the swinging arm that the regulating means contacts.
