<p>PURPOSE:To perform a job for unjamming so easily without any hindrance by dividing a printer body into two parts with a paper feed passage as the border, installing a cover body being free of opening or closing, and interlocking it with a lever, then exposing a developing unit, whose top face is set down to a paper guideway, after being slid outward. CONSTITUTION:A developing unit 6, whose circular top face 6a is set down to a paper guideway, is attached to a printer body 1 equipped with both paper cassettes 3A, 3B at the upper part pushably to the front of the body 1 along a circular guide groove 2 of a body frame via each sliding plate 8 installed at both sides. On the other hand, a resist roller 12, a transfer charger 13, a fixing unit 14 or the like are installed in the body 1 after covering the front with a paper feed passage 5 as the border, and such a cover body as being free of opening or closing with a fulcrum shaft 11 at the supporting point is installed there, while the whole developing unit 6 is made so as to be exposable to the front of the body 1 via the pivoted lever 16. With this constitution, unjamming and inspection plus replacement of the developing unit are facilitated.</p> |
