PROBLEM TO BE SOLVED: To provide a device capable of performing detection of a car body without an influence on car shape data, even in the case where water droplets, garbage, dirt and the like are attached to a light emitting part and a light receiving part.SOLUTION: A car washing machine includes: a car shape detection device which takes in a shape of an automobile as car shape data according to relative movement of the automobile and a body frame; a car washing processing device which acts on a car body surface based on the car shape data 10 taken in from the car shape detection device; and a car entering sensor which detects an end part of the automobile. The car shape detection device includes: a car shape sensor 10 comprising a light emitting part 10a in which a plurality of light emitting elements L are arrayed vertically and a light receiving part 10b in which a plurality of light receiving elements R opposing to the light emitting elements L of the light emitting part 10a are arrayed vertically; and a car shape detection part 24 for detecting presence/absence of a car body depending on a light receiving level in the light receiving elements R according to the light emission of the light emitting elements L. A threshold value of the light receiving level for determining presence/absence of the car body changes before and after the detection of the end part of the automobile by the car entering sensor.SELECTED DRAWING: Figure 3

    【課題】発光部や受光部に水滴・ゴミ・汚れ等が付着している場合であっても、車形データへの影響がなく、車体の検出が行える装置を提供すること。【解決手段】自動車と本体フレームの相対移動に伴い、自動車の形状を車形データとして取り込む車形検出装置と、車形検出装置から取り込んだ車形データ10に基づいて車体面に作用する洗車処理装置と、自動車の端部を検出する入車センサとを備えた洗車機において、車形検出装置は、複数の発光素子Lを上下に配列した発光部10aと、該発光部10aの発光素子Lと対向する複数の受光素子Rを上下に配列した受光部10bとからなる車形センサ10と、発光素子Lの発光に伴う受光素子Rでの受光レベルによって車体の有無を検出する車形検出部24とを備え、車体の有無を判断する受光レベルのしきい値を、入車センサで自動車の端部を検出する前後で変更する。【選択図】図3
