検出機構。 In a paper detection mechanism that detects the presence or absence of paper using a combination of a light emitting element and a light receiving element that can be mounted in the paper hopper of an information processing output printer or printing machine, the optical path from the light emitting element to the light receiving element is connected to the paper multiple times. Paper detection mechanisms arranged so that they intersect.
