PURPOSE: A device for supplying a paper is provided to enable a user to confirm a size of a paper stored in a cassette without taking the cassette out of a printer main body. CONSTITUTION: A size sensing device of a paper supplier is composed of a link member(220) installed to possibly rotate, centering on a hinge shaft(223) prepared in a cassette, a rack member(230) slid by being connected to the link member, a rotary plate(240) rotated by butting with the rack member and a sensor unit(300) for sensing a size of a paper by recognizing a mark prepared on the rotary plate. Herein, the rack member is butted with the rotary plate supported to rotate on one side wall of the cassette, and the plural projections(241) are formed as a make for pointing the size of each paper on the rotary plate. Thereby, the size of the paper is corresponded in each case by using the number of the case caused by the arrangement of the projection, and the sensor unit senses the size of the paper.
