发明名称 Optical reading device
摘要 A portable communication equipment having an optical reading device for optically reading information on a sheet. A contact detection unit for detecting that a contact surface of the optical reading device with the measured matter contacts any of the information and a surface of sheet having the information thereon, the contact detection unit being provided on the contact surface. A reading unit having a light source unit and a light detection unit, wherein the light source unit is put in an operation state when the contact detection unit detects the contact of any of the measured matter and the surface of the sheet having the information thereon, and irradiates light from the contact surface to the information, and the light detection unit is put in the operation state when the contact detection unit detects the contact surface and any of the information and the surface having the information formed thereon, receives, from the contact surface, reflected light from the information, the light being irradiated from the light source, and converts the reflected light into an electric signal. A signal processing unit for analyzing the electric signal obtained by the light detection unit and changing to the electric signal into electrical information. A transmitting unit for transmitting the information, the information being read by the optical reading device. <IMAGE> <IMAGE> <IMAGE>
