第１項記載の用紙の重送検知装置。[Claims for Utility Model Registration] (1) A device that includes a swinging member disposed on the side of a paper transport path and detects that the swinging member is swung by the paper passing through the paper transport path. , A substantially L-shaped plate member to which a double feed detection means is attached is arranged in correspondence with the swinging member, and a rising portion of the plate member supports a rotation angle detection means having a shaft fixed to the swinging member. A horizontal member configured as a member and set at approximately the same height as the paper conveyance surface of the lower guide plate is arranged so that the lower part of the contact piece of the swinging member is in contact with the horizontal member, and is configured separately from the paper conveyance path. A double feed detection device for paper sheets, characterized in that the plate member is configured to support the entire rotation angle detection means of the swinging member. (2) The plate member to which the double feed detection means is attached is supported by a buffer means against a frame that supports the paper conveyance path, so that it is not affected by vibrations of the main body of the apparatus. A paper double feed detection device according to claim 1 of the utility model registration claim. (3) Set the paper pressing part on the downstream side of the support shaft of the swing arm that presses the paper in the detection part, and determine the ratio of the horizontal distance to the vertical distance between the support shaft and the pressing part. 2. The paper double feed detection device according to claim 1, wherein: is set to 0.5 or less.
