Claims

[Claims for Utility Model Registration] (1) The bottom plate on which the paper is placed is raised so that it comes into contact with the paper with a predetermined pressing force against the nudger roller of the paper feeder, and In a paper feeding device configured to feed paper by rotating a roller, the raising operation of the bottom plate is controlled by a timer or the like set in a control device, and the movement of the bottom plate is controlled from the upper limit position of the paper. A detection device is provided in the upper part of the paper at a position close to the paper feeding device in order to detect the rising state of the paper, and the drive mechanism that raises the paper is directly stopped by the detection device. A paper rising position detection device characterized by comprising: (2) By raising the bottom plate on which the paper is placed so that it contacts the paper with a predetermined pressing force against the nudger roller of the paper feeder, and by rotating the roller of the paper feeder, In a paper feeding device configured to feed paper, a detection device having two detection means is provided so as to detect an upper limit position and a lower limit position of the paper, and an operation for controlling the rise of the paper is provided. A rising position detection device for paper, characterized in that it is configured as follows. (3) By raising the bottom plate on which the paper is placed so that it contacts the paper with a predetermined pressing force against the nudger roller of the paper feeder, and by rotating the roller of the paper feeder, In a paper feeding device configured to feed paper, a detection device having two detection means is provided so as to be able to detect an upper limit position and a lower limit position of the paper, and a detection device having two detection means is provided so as to detect an upper limit position and a lower limit position of the paper. A sheet of paper characterized in that, in order to detect the rising state of the paper, the drive mechanism for lifting the paper is directly stopped by a detection device at a position close to the paper feeding device. rising position detection device.
