<p>PURPOSE:To make it possible to set a copying sheet cassette removably in a housing, by automatically setting a press-contact mechanism into an operative condition or an inoperative condition in association with manipulation for setting or removing the cassette. CONSTITUTION:When a copying sheet cassette 38 is inserted into a cassette receiving section 36 through an opening formed in the left wall of a copying machine housing 2 and then is moved in the direction in which the cassette 38 is inserted, as indicated by the arrow 68, a pair of actuating pieces 18 which are provided on the front wall of a cassette body 58 abut at their lower end against the upper surface of the associated guide member 128 and are slid on the upper surface, exceeding over an abutting part 120 in a predetermined way. When the copying sheet cassette 38 is moved in the direction as indicated by the arrow 68, the cassette 38 abuts against the front end of a releasing level 102 just before it being set in the cassette receiving section 36 as in the predetermined way, and therefore, the releasing lever 102 is turned clockwise overcoming the resilient bias force of a leaf spring 112, thereby the copying sheet cassette 38 is set in the cassette receiving section 36 as in the predetermined way.</p> |
