APPARATUS AND METHOD OF MEASURING INSIDE DIMENSION OF FOOTWEAR

PROBLEM TO BE SOLVED: To provide a technique that makes accurate measuring possible of the inside dimension of footwear.SOLUTION: The footwear measuring apparatus for measuring the inside dimension of footwear includes: an emitter/receiver part that emits a laser beam and receives the laser beam reflected in an article of footwear; a light guide part that irradiates the article of footwear at the tip end with the laser beam emitted from the emitter/receiver part, with the reflected laser beam in the article of footwear made incident to the tip end to be received by the receiver part and that, in at least a part of the light path of the laser beam from the emitter/receiver part to the tip end, in at least a part of the periphery of the laser beam, protects the light path of the laser beam; a control arm that controls the position of the tip end of the light guide part and the direction of the light guide part; and a processing part that controls the direction of the light guide part and the position of the tip end of the light guide part by driving the control arm and that, on the basis of the laser beam received by the receiver part, the inside dimension of the article of footwear is calculated.SELECTED DRAWING: Figure 1 【課題】履物の内部寸法を良好に計測することを可能にする技術を提供する。【解決手段】履物の内部寸法を測定する履物測定装置は、レーザ光を発光し、前記履物で反射した前記レーザ光を受光する発受光部と、前記発受光部から発光した前記レーザ光を先端部から前記履物に照射し、前記履物で反射した前記レーザ光を前記先端部にて入射して前記受光部に受光させ、前記発受光部から前記先端部までの前記レーザ光の光路の少なくとも一部において前記レーザ光の周囲の少なくとも一部において、前記レーザ光の光路を保護する導光部と、前記導光部の前記先端部の位置および前記導光部の方向を制御する制御アームと、前記制御アームを駆動して前記導光部の方向および前記導光部の前記先端部の位置を制御し、前記受光部で受光された前記レーザ光に基づいて、前記履物の内部寸法を算出する処理部と、を有する。【選択図】図１
