を特徴とする光学式文字読取装置。[Scope of Claim for Utility Model Registration] A conveying means for conveying a form; a light source for irradiating light onto the form; a reading sensor for detecting reflected light from the form irradiated by the light source; and an output of the reading sensor. A recognition means that recognizes the format of the form and an image written on the form based on the signal, a detection member that comes into contact with the top surface of the carried form and is displaced, and a potentiometer that converts the amount of displacement of the detection member into an electrical signal. an analog/digital converter that converts the output of the potentiometer into a digital signal, an output value X o of the analog/digital converter when the detection member is not in contact with the form, and the detection The difference (X n
-Xo ) with a predetermined threshold value XTH based on the format of the form recognized by the recognition means, and when a result of XTH<( Xn -Xo ) is obtained, the documents are overlapped. 1. An optical character reading device comprising: a control means for detecting that a character is being conveyed.
