〔産業上の利用分野〕
本発明は画像形成装置、特に複数の選択可能な用紙カセ
ットを有する画像形成装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image forming apparatus, and more particularly to an image forming apparatus having a plurality of selectable paper cassettes.
従来の画像形成装置は選択されていた用紙カセットを記
憶する機能を有していなかった。Conventional image forming apparatuses do not have a function of storing the selected paper cassette.
上述した従来の画像形成装置は電源切断直前に選択して
いた用紙カセットを記憶し、電源再投入時に記憶してい
た用紙カセットを自動的に選択するという機能がないの
で、電源投入後用紙カセットの選択をやり直さなければ
ならないという欠点があった。The conventional image forming apparatus described above does not have a function to memorize the paper cassette that was selected immediately before the power was turned off, and automatically select the memorized paper cassette when the power is turned on again. The drawback was that the selection had to be made again.
本発明の目的は前記課題を解決した画像形成装置を提供
することにある。An object of the present invention is to provide an image forming apparatus that solves the above problems.
前記目的を達成するため、本発明はマイクロプログラム

性メモリとを有するものである。In order to achieve the above object, the present invention provides a microprogram-controlled image forming apparatus including a paper feeding mechanism having a plurality of selectable paper cassettes, and a paper cassette that is selected immediately before the image forming apparatus is powered off. It has a non-volatile memory.
次に本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

揮発性メモリ５に・書き込む。The microprocessor 1, while using the image forming apparatus,
When a paper cassette is selected, information on which paper cassette is selected is read from the hopper control section 4 and written into the nonvolatile memory 5.

直前の用紙カセットを選択する。Thereafter, even if the image forming apparatus is used and the power is turned off, the contents of the nonvolatile memory 5 will not be erased. When the power is turned on again, the microprocessor 1 reads the contents of the non-volatile memory 5, provides the information to the hopper control section 4, and selects the paper cassette immediately before the power was turned off.

を自動的に選択することが可能となる。According to the present invention, in a microprogram-controlled image forming apparatus, the image forming apparatus has a built-in nonvolatile memory 5, and the nonvolatile memory 5 stores the paper cassette that was selected immediately before the image forming apparatus was powered off. When the power is turned on again, the paper cassette that was selected immediately before the power was turned off can be automatically selected.
〔発明の効果〕
