PURPOSE:To optionally switch the feeding of recording paper either to many paper feeding or to little paper feeding, and switch this paper feeding easily and safely. CONSTITUTION:Either of a paper feeding unit or a many paper feeding mount is elevated to a paper feeding mechanism at one place to be positioned, and then papers are fed. From a cassette, the mounting/demounting condition of the cassette on/from the paper feeding unit is outputted as a signal showing the presence or absence of the cassette by cassette existence detecting means 114 and 100a. A device is started/stopped by the pushing operation of a power source switch 116. By a mode deciding means 100b, a cassette paper feeding mode is adopted when the power switch 116 is turned on and the cassette exists, and a many paper feeding mode is automatically set when the power source switch 116 is turned on and the cassette is unexisting. By a mode control means 100f, the cassette or the many paper feeding mount on a corresponding paper feeding unit is positioned to a paper feeding mechanism part to make recording papers a paper feeding possible condition. |
