PURPOSE: To achieve the reduction of an accumulation tolerances by miniaturization, wt. reduction and the reduction of the number of parts and fixtures and the enhancement of assembling properties by holding a pump mechanism part, a waste ink absorbing element, a separation means, a pinch roller part and a sheet discharge part on a base part and forming a paper supply stack part by the base part. CONSTITUTION: A base 15 holds a pump mechanism part, a pinch roller part, a sheet discharge part and a waste ink holding element and also holds a paper supply stack part, a separation means and a drive transmission part and forms a base unit as a whole. A chasis unit consists of the fed roller 52 of a chasis 50, a carriage guide shaft 3 and the guide rail 4 holding a paper feed roller shaft 53, a carriage 2 and a spur 61. Herein, the fitting groove of the chasis 50 is matched with the boss 15A of the base 15 and the pawl part of the base 15 is fitted in the hole of the chasis by revolving the chasis unit around the boss 15A to unify both units and, since the contact part is energized by a spring, the positional accuracy and assembling properties at the time of the union of both units are enhanced. |
