Abstract
An improved sheet feeding apparatus for use in printers, typewriters, facsimile equipment and copying machines. The apparatus comprises a cassette loading system wherein the cassette may be automatically loaded into operative position, and locked therein, in a sequence of two substantially transverse movements which prevent sheet misfeed and require a minimum of operator activity.
Claims11
Sheet feed apparatus for feeding sheets from a stack to a utilization device having internal support members and sheet removing means, wherein the stack of sheets is contained within a receptacle movable in a first direction into and out of said utilization device and movable in a second direction toward and away from said sheet removing means, the improvement being characterized by including
- slider means on opposite side walls of said receptacle,
- guide means on said support members, for receiving said slider means and for controlling the direction of movement of said receptacle, and
- reciprocable cam means supported by said guide means, said cam means having a cam surface for simultaneously urging said slider means in said first and second directions, whereby as said slider means moves within said guide means said cam means initially urges said slider means out of said utilization device in said first direction and subsequently urges said slider means in said second direction to lock said receptacle in place within said utilization device and to move said receptacle so that said sheet removing means is in driving contact with the sheets in said stack.
