ABSTRACT:
A media sensor68includes a cap85with a common opening85bfor restricting the beam spread of light emitted from a light-emitting element82and the range of light receivable by a light-receiving element83, while suppressing the effects of disturbance. Accordingly, the media sensor68can prevent a decline in detection accuracy while using inexpensive elements with low directivity. Since the light-emitting element82and light-receiving element83are oriented perpendicularly to the paper P, the media sensor68is superior to sensors equipped with elements disposed at an angle to the paper P by avoiding a decline in detection accuracy caused by errors in the angular positioning of the elements, errors in angular positioning of the sensor itself, and the like, and by reducing the space required in the sensor to dispose the elements, thereby reducing the size of the sensor.
