초록 ▼

An optical reader having a reading head which includes a light source, an optical system and in imaging device such as a CCD. An opening is formed in a tip portion of the reading head which forms an area in which an information pattern to be read is positioned. The information pattern is illuminated by the light source, and the light reflected from the information pattern is sensed by the CCD. A closing plate is slidably supported by guide grooves provided on edge portions of the opening. The opening is opened and closed by the closing plate. The closing plate has a plurality of notches to provide flexibility.

대표청구항 ▼

[ We claim:] [1.] An optical reader for optically reading an information pattern representing coded data, said reader comprising:a reading head which optically senses said information pattern, said reading head being provided with an opening forming an area in which said information pattern is positioned for sensing;a closing plate that opens and closes said opening, said opening being completely closed by said closing plate when said optical reader is not in use, whereby foreign matter is prevented from entering through said opening; anda power switch that actuates said optical reader, said power switch comprising a limit switch having an operation member, said power switch being turned ON and OFF in association with opening and closing of said closing plate, said operation member being engaged by said closing plate to close said limit switch when said closing plate fully opens said opening, and being released from said closing plate to open said limit switch when said closing plate is not fully opened.
