PROBLEM TO BE SOLVED: To reduce apparatuses for discriminating the vehicle type at a tollgate with a narrow site.SOLUTION: A vehicle detector includes a plurality of light receiving and emitting units each including a light emitting unit, a first light receiving unit, and a second light receiving unit in the height direction. In the vehicle detector, a positional relationship across a lane between a position of the light emitting unit and the first light receiving unit constituting at least one light receiving and emitting unit and a position of the second light receiving unit constituting the light emitting and receiving unit, and a positional relationship across the lane between a position of the light emitting unit and the first light receiving unit constituting another light receiving and emitting unit and a position of the second light receiving unit constituting the light receiving and emitting unit are opposite to each other across the width direction of the lane. The light emitting unit provided on one side in the width direction of the lane emits inspection light toward the other side and the first light receiving unit provided in relation to the light emitting unit on the other side in the width direction of the lane receives the inspection light. The second light receiving unit provided in relation to the light emitting unit on one side in the width direction of the lane receives reflected light of the inspection light.SELECTED DRAWING: Figure 1

    【課題】敷地が狭い料金所において車種判別のための機器を削減する。【解決手段】車両検知器が、発光部と第一受光部と第二受光部とにより構成される受発光ユニットを高さ方向に複数備える。車両検知器において少なくとも1つの受発光ユニットを構成する発光部と第一受光部の位置と当該受発光ユニットを構成する第二受光部の位置との車線を隔てた位置関係と、他の受発光ユニットを構成する発光部と第一受光部の位置と当該受発光ユニットを構成する第二受光部の位置との車線を隔てた位置関係とが、車線の幅方向を隔てて逆となるよう構成される。そして車線の幅方向一方側に設けられた発光部が他方側に向けて検査光を発光し、車線の幅方向他方側に発光部に関連して設けられた第一受光部が検査光を受光する。また車線の幅方向一方側に発光部に関連して設けられた第二受光部が、検査光の反射光を受光する。【選択図】図1
