SCANNER, AND METHOD FOR PRODUCING PRINTER

To produce a printer in which a printing unit is adjusted with high precision.SOLUTION: A scanner comprises: a scanning unit that performs intermittent scanning in which it moves intermittently; a stop state analysis unit that compares with each other a stop time image obtained through scanning of an identification pattern on a medium at a stop position where the movement of the scanning unit is temporarily stopped, and a resumption time image obtained through scanning of the identification pattern at the stop position at a timing subsequent to the timing when the stop time image is obtained, and based on a result of the comparison, determines whether the medium has moved; and a scanning control unit that, when the medium has moved, interrupts the intermittent scanning that is temporality stopped, and when the medium has not moved, continues the intermittent scanning that is temporarily stopped.SELECTED DRAWING: Figure 1 【課題】高精度に印刷部が調整された印刷装置を生産する。【解決手段】間欠的に移動する間欠スキャンを行うスキャン部と、スキャン部の移動が一時停止する停止位置において、媒体上の識別模様のスキャンにより得られる停止時画像と、停止時画像が得られるタイミングよりも後のタイミングで、停止位置における識別模様のスキャンにより得られる再開時画像と、を比較し、比較結果に基づいて、媒体が動いたか否かを判断する停止状態解析部と、媒体が動いた場合には、一時停止中の間欠スキャンを中断させ、媒体が動かなかった場合に、一時停止中の間欠スキャンを継続させるスキャン制御部とを備える。【選択図】図１
