Optical object identification apparatus, and printing apparatus and object classification apparatus using same |
摘要 |
An optical object identification apparatus has a light emitting-side optical system ( 23 ), a light receiving-side optical system ( 26 ), and a signal processing section ( 29 ). The light emitting-side optical system ( 23 ) irradiates light from a light emitting device ( 21 ) via an objective lens ( 22 ) to a moving target object ( 27 ) such as printing paper sheets. The light receiving-side optical system ( 26 ) receives reflected light from the target object by means of the light receiving device ( 25 ) via an objective lens ( 24 ), and outputs an output signal with a waveform corresponding to the surface projections and depressions of the target object ( 27 ). The signal processing section ( 29 ) executes signal processing on the output signal by at least one signal processing method to identify the target object.
