IMAGE FORMATION DEVICE, IMAGE FORMATION CONTROL METHOD, AND IMAGE FORMATION CONTROL PROGRAM

PROBLEM TO BE SOLVED: To efficiently perform printing by using a long sheet of paper by an image formation device for cut paper.SOLUTION: An image formation device is equipped with a control part for executing control to create an image request signal for requesting image formation on each sheet of a regular size, create an effective region signal for each sheet corresponding to the sheet length in the sheet conveyance direction in correspondence with the image request signal, and read out image data based on the effective region signal for forming an image. When image formation is performed using a long sheet whose sheet length in the conveyance direction is longer than a sheet of a regular size, the control part executes control to repeat the formation of an image request signal for the sheet of a regular size, the formation of a basic effective region signal corresponding to the sheet of a regular size based on the image request signal, and the formation of a completion notice corresponding to the completion of the basic effective region signal, and executes control to create a continuous effective region signal which is continuous in correspondence with the long sheet by using as a trigger an image request signal at the start of image formation for the long sheet, and read out image data based on the continuous effective region signal for forming an image on the long sheet.SELECTED DRAWING: Figure 1 【課題】カット紙用の画像形成装置で、長尺用紙を用いて効率良くプリントする。【解決手段】定型サイズの各用紙への画像形成を要求する画像要求信号を生成し、画像要求信号に対応して用紙の搬送方向の用紙長に対応した有効領域信号を用紙毎に生成し、該有効領域信号に基づいて画像データを読み出して画像形成するよう制御する制御部を備えた画像形成装置で、定型サイズの用紙よりも搬送方向の用紙長が長い長尺用紙を用いて画像形成する際に、定型サイズの用紙に対する画像要求信号の生成と、画像要求信号に基づく定型サイズの用紙に対応した基本有効領域信号の生成と、基本有効領域信号の終了に応じた終了通知の生成とを繰り返すように制御すると共に、長尺用紙に対する画像形成開始時点の画像要求信号をトリガとして長尺用紙に対応して連続した状態の連続有効領域信号を生成し、連続有効領域信号に基づいて画像データを読み出して長尺用紙に画像形成する、【選択図】図１
