To allow for performing processes of reading optical codes and determining reading stability while minimizing an increase in conveyance system cost and preventing deterioration in work efficiency.SOLUTION: A CCD 112 captures images. A processor 122 reads a one-dimensional code contained in image data captured by the CCD 112 and outputs a signal upon completion of a reading process when the number of successful reads of the one-dimensional code reaches a determination reference value. The processor 122 also determines reading stability during a period from an initial successful read to the completion of the reading process, and outputs predictive maintenance information (PMI) representing a reading stability determination result.SELECTED DRAWING: Figure 6 【課題】搬送システムのコストの増加を抑え、作業効率の低下を防ぎつつ、光学コードの読取処理と読取安定度の判定処理を行うこと。【解決手段】ＣＣＤ１１２は、撮像を行う。プロセッサ１２２は、ＣＣＤ１１２が撮像した画像データに含まれる一次元コードを読取り、一次元コードの読取成功回数が判定基準値に達した読取処理完了時に信号を出力する。また、プロセッサ１２２は、初回の読取成功時から読取処理完了時までの期間において読取安定度を判定し、読取安定度の判定結果を表す予知保全情報（ＰＭＩ）を出力する。【選択図】図６
