摘要： PROBLEM TO BE SOLVED: To provide a paper feeding device capable of freely controlling a paper gap at the time of feeding paper to a device main body at low cost without increasing the size of the paper feeding device. SOLUTION: A pick roller and a feed roller are driven by a single motor. Instead of a gear, an electromagnetic clutch is provided on a transmission path of driving force of the motor to the pick roller. A paper sensor is provided in the downstream side of the feed roller. By detecting the rear end of preceding paper by the paper sensor, transmission timing of driving force to the pick roller by the electromagnetic clutch is determined, and a paper gap during paper conveyance is controlled, Meanwhile, the paper sensor may be provided in the vicinity of the pick roller before the feed roller.

摘要： PROBLEM TO BE SOLVED: To obtain an efficient mechanism, capable of being utilized also as a handy scanner by detaching a scanner device from a base device by confronting medium guides provided on the scanner device and the base device, arranging them so as to be gradually narrow toward a medium drawing port and providing at least one medium guide with a level difference part so as to limit the inflow of a medium toward the medium drawing port step by step. SOLUTION: Two paper guides 32 and 33 are arranged face to face, so as to gradually narrow toward a lower paper drawing port 35, and even if plural pieces of paper are set, few sheets of paper are automatically narrowed at the top end. When there are a large number of papers to be set, jamming occurs easily because of the pressure of paper, but by providing a level difference part 34 in the middle of the paper guide 32 in dealing with this problem, the pressure at the top end of paper is released partially so that pressure can be prevented from being concentrated in the paper drawing port 35. Moreover, the level difference part has a smooth inclination so as to slide paper down toward the paper drawing port 35.
