Summary: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 CMOS 112 captures images. A processor 122 reads an optical code contained in image data captured by the CMOS 112 and outputs a signal upon a successful read of the optical code. The processor 122 also computes a first contrast during teaching and a second contrast during the successful read, and determines reading stability on the basis of a reduction rate from the first contrast to the second contrast.SELECTED DRAWING: Figure 4 【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】ＣＭＯＳ１１２は、撮像を行う。プロセッサ１２２は、ＣＭＯＳ１１２が撮像した画像データに含まれる光学コードを読取り、光学コードの読取に成功した場合に信号を出力する。また、プロセッサ１２２は、ティーチング時における第１コントラストと、読取成功時における第２コントラストをそれぞれ計算し、第１コントラストに対する第２コントラストの低下率に基づいて読取安定度を判定する。【選択図】図４
