Abstract: A photoelectric rotary encoder includes a light source that emits a light beam, a returning section that returns the emitted light beam to a direction opposite to an emitting direction of the beam, and a photodetector that is disposed on a substrate on which the light source is disposed and that detects the returned light beam via a disk having a detection pattern section. The photoelectric rotary encoder detects rotational displacement of the disk based on the detected returned light beam. In this photoelectric rotary encoder, an optical element that lets a stray beam component of the light beam from the light source escape via a side surface of the optical element, is disposed in front of the substrate on which the light source and the photodetector are disposed. The optical element covers the substrate and integrates the optical element and the substrate.

Abstract: A network apparatus is provided, which allows another network apparatus to recognize the disconnection with reliability, if a power supply to the network apparatus is interrupted. A control unit operating with a first power supply outputs a first signal, which is level-converted and supplied as a second signal to an intermediate potential supply unit operating with a second power supply. In the intermediate potential supply unit, a switch receives a reset signal as a switch signal and outputs, when the power supply is interrupted, a ground potential to a driver instead of the second signal. As a result, an intermediate potential supplied to a cable is forcibly set to the ground potential.
