Abstract

PURPOSE:To eliminate vertical dead space and make it possible to stably deliver cut paper by long paper delivering stroke by a method wherein a paper delivering device, with which the cut paper is delivered normal to its transferring direction at printing, consists of a paper delivering slider, which moves rectilinearly, and its driving mechanism. CONSTITUTION:When a driving gear 115 is rotatingly driven by the motor 111 of a paper delivering device 10 to the direction indicated with the arrow (m), a driving arm 117 is integrally rotated to the same direction as mentioned above so as to drive a guide pin 109 in a guide groove 108 by means of an elongated hole 117 to the direction indicated with the arrow (d). Thus, the guide pin 109 and a guide piece 103b are guided by the guide groove 108, resulting in rectilinearly moving a paper delivering slider bar 103 on a paper delivering guide 107 by a long paper delivering stroke to the direction indicated with the arrow (d) ranging from the forwarding motional position to the backwarding motional position. Thus, by the rectilinear motion of the slider 103 to the direction indicated with the arrow (d), a pair of paper delivering pieces 104 push the two points at the rear end of a cut paper parallel to each other, resulting in stably and parallel delivering the cut paper from the higher positional part to the lower positional part of a paper delivering rack.
