Abstract
An optical reading device optically reads information on a surface. The optical reading device includes a contact detection unit, a reading unit, and a signal processing unit. The contact detection unit provides a signal when the optical reading device is within a threshold distance of a surface having information. The reading unit includes a light source unit and a light detection unit, wherein the light source unit irradiates light on the surface and the light detection unit detects light reflected from the surface, based on the signal from the contact detection unit. The signal processing unit identifies the information based on analyzing the light reflected from the surface. In addition, the optical reading device may be implemented in a mobile communications device, which also includes a transmitting unit that transmits the information identified by the signal processing unit.
