Abstract
A height gauge has a touch signal probe provided on a slider vertically movably supported on a support for the purpose of measuring the dimensions or the like of an object by bringing the probe into contact with the object. A rack is formed on the support, and a driving shaft is disposed on the slider, the driving shaft having a pinion engaged with the rack. To the driving shaft are secured a pulley to which the turning force from a motor is transmitted and a control wheel for manually rotating the driving shaft. A clutch member is interposed between the pulley and the control wheel. When the clutch member is engaged with the pulley, the slider is automatically moved up and down, while when the clutch member is engaged with the control wheel, the slider can be manually moved up and down. The height gauge further includes a control circuit which stops the drive of the motor when the touch signal probe generates a touch signal and which holds the indication of a measured value being displayed at that time.
