Abstract

A printing apparatus and a method to pick up paper using the printing apparatus. The printing apparatus includes a main body; a signal supply section to supply a signal indicative of a type of a paper to be fed from a paper feeding section provided in the main body; at least one friction member provided to form an angle within a predetermined range in relation to the leading edge of a paper picked up from the paper feeding section so that predetermined frictional force is applied to the leading edge of the paper, the friction member being installed to changeable structure within the range; at least one elastic member to elastically bias the friction member in a first direction; a cam unit movably installed to the main body, the cam unit forcibly moving the friction member in a second direction opposite to the first direction to change the structure of the friction member while the cam unit is being moved by driving force; a driving force supply unit movably installed in the main body, the driving force supply unit to supply driving force to the cam unit at the time of being moved; and a control section to control the driving of the driving force supply unit based on the signal in relation to the type of the paper supplied from the signal supply section.

Description

technical field [0001] The present invention relates to a printing apparatus, and more particularly to a printing apparatus having a flexible structure of friction elements to sort a plurality of sheets according to their respective types. Background technique [0002] Typically, printing devices such as laser printers and inkjet printers include a paper feeding mechanism for individually feeding each sheet of paper into a printing stage of the printing device. [0003] Generally, such a paper feeding device includes: a paper cassette portion on which a plurality of sheets of paper are loaded; at least one pick-up roller for feeding in one direction the plurality of sheets of paper loaded on the paper cassette portion; and at least one friction member, It is arranged at a predetermined angle with respect to the sheet conveying direction, thereby individually sorting a plurality of sheets supplied and fed by the pickup roller. [0004] The friction member is arranged at a pr...
