ることを特徴とする光学情報読取装置。Light from a light source is irradiated onto the letters or marks written on the form, the reflected light from the form is passed through a filter, the wavelength of the reflected light is selected, and the light is received by the light-receiving element. In an optical information reading device that reads characters or marks written on the form, the light source is a light source with a wavelength that can be read by most writing utensils used to write characters or marks on the form, and furthermore, there is a light source between the light source and the form. According to the plurality of filters having different wavelengths and the type of dropout color used in the plurality of filters on the form, the characters or marks written on the writing instrument can be read, and the dropout color can be read. An optical information reading device characterized in that it is equipped with a switching means that is switched and used so that it is always dropped out.
