To precisely detection rotation deficiency of each wheel at a low cost even if a number of wheels travel continuously without depending on environment in which carriages are provided.SOLUTION: A rotation deficiency detector detects rotation deficiency of wheels provided on a carriage traveling on a rail. Arrival of the weeks is detected each by first and second detection sections that detect arrival of the wheels at predetermined imaging positions and are placed side by side along an advance direction of the carriage, surfaces of the wheels that are fixed to the wheels and include a predetermined mark rotating following rotation of the wheels are captured, based on output signals for detection of the wheels outputted from the first and second detection parts, respectively, two kinds of captured images are generated each, and image processing is performed to the two kinds of generated captured images, thus detecting rotation deficiency of the wheels.SELECTED DRAWING: Figure 4

    【課題】台車が設けられる環境に依らず、かつ、連続して多数の車輪が走行する場合であっても、コストをかけることなく各車輪の回転不良を精度よく検出すること。【解決手段】本発明は、レール上を移動する台車に設けられた車輪の回転不良を検出するものであり、前記車輪が所定の撮像位置に到達したことを検出する、前記台車の進行方向に沿って所定の間隔をあけて併設された第1及び第2の検知部により、前記車輪の到着をそれぞれ検出し、前記第1及び第2の検知部からそれぞれ出力された、前記車輪の検出に係る出力信号に基づいて、前記車輪に固定されており、かつ、当該車輪の回転に伴い回転する所定のマークを含む前記車輪の面を撮像して、2種類の撮像画像をそれぞれ生成し、生成された2種類の前記撮像画像に対して画像処理を行うことで、前記車輪の回転不良を検出する。【選択図】図4
