There is illustrated and described a printing device having an integrated paper feeding apparatus adapted for supplying individual sheets of paper to the printing device to effect printing thereon. The integrated printer and paper feeding apparatus of the present invention is particularly suitable for use in word processing systems where the information to be printed in hard copy is contained in a memory device such as a floppy disk or the like. The apparatus may be directly linked to word processing equipment to receive the text of material to be printed. In addition to having the capability of automatically feeding individual sheets of paper from one or more paper trays to the printing device, the apparatus includes an automatic envelope supply mechanism for supplying individual envelopes to the printing device, as well as a manual paper feed option. After effecting printing on the paper or envelope, an ejector mechanism ejects the printed paper from the apparatus and into a receptacle in collated form. All components of the apparatus are enclosed in a single housing having suitable sound reducing material provided to reduce the operational noise of the apparatus. The housing is provided with openings to receive the paper trays and an envelope tray, as well as a top liftable cover designed to provide easy access to the components of the apparatus within the housing.

A paper loading assembly for a printing device, said printing device including paper advancing means for advancing a sheet of paper within said printing device, said paper loading assembly comprising: paper storing means for storing a plurality of individual sheets of paper, said paper storing means being insertable into and withdrawable from said printing device and having first and second spaced cam surfaces thereon; paper feeding means for feeding individual sheets of paper from said paper storing means along a paper feed path to said paper advancing means when said paper storing means has been inserted into said printing device; engaging means movable between an operative position and an inoperative position, said engaging means being biased toward said operative position so as to be engageable with said paper storing means when said paper storing means has been inserted into said printing device to position the plurality of individual sheets of paper within said paper storing means into a position for feeding at least one of said individual sheets by said paper feeding means along said paper feed path, and said engaging means being movable to said inoperative position to permit said paper storing means to be inserted into and withdrawn from said printing device; and a cam follower member engageable with said first and second cam surfaces on said paper storing means for controlling the positioning of said engaging means during insertion and withdrawal of said paper storing means relative to said printing device, said cam follower member and said first and second cam surfaces on said paper storing means being so arranged that said cam follower member engages said first cam surface upon initial insertion of said paper storing means into said printing device to move said engaging means from said operative position to said inoperative position and thereafter engages said second cam surface upon further insertion of said paper storing means within said printing device to permit said engaging means to return to said operative position and into engagement with said paper storing means when insertion of said paper storing means into said printing device has been completed, and so arranged that said cam follower member engages said second cam surface upon initial withdrawal of said paper storing means from said printing device to move said engaging means from said operative position to said inoperative position and thereafter engages said first cam surface upon further withdrawal of said paper storing means from said printing device to premit said engaging means to return to said operative position when withdrawal of said paper storing means from said printing device has been completed, whereby said engaging means is automatically moved to said inoperative position upon initial insertion or initial withdrawal of said paper storing means relative to said printing device and automatically returned to said operative position after said paper storing means has been inserted into or withdrawn from said printing device.
