Abstract

In a cassette type sheet supplying device, two or more adjoining spaces for installing standard cassettes therein are joined into a continuous space to enable a large cassette to be installed in the space in lieu of two stantard cassettes. When no cassette is installed or a standard cassette is installed, a paper feeding unit is pulled to the paper feeding position by a spring, and a claw portion of a lock material engages lock holes formed on paper feeding unit side frames so that the paper feeding unit is held to the paper feeding position. When the large cassette is inserted in the cassette installation space, a lock release projection formed on the large cassette comes in contact with a projection of the lock material and extends it to the outside. At this time, the claw portion comes off from the lock hole. When the large cassette is further inserted, the paper feeding unit is pushed through a cushion material. A paper feeding unit guide roller retreats to the retracted position being guided by a guide hole. According to the cassette type sheet supplying device thus constructed, a plurality of standard cassettes can be installed in a continuous space or one large cassette can be installed in the space in lieu of the standard cassettes.
