Abstract

A light receiver outputs a log indicating at least one of an operating status of a multiple optical axis photoelectric sensor and an environment surrounding the multiple optical axis photoelectric sensor, at the time of an output being turned off.

First claim

What is claimed is:

1. A status notification device, configured to change an output between two values depending on whether an object is detected, comprising:
a monitoring unit that monitors at least one of an operating status of the status notification device and an environment surrounding the status notification device based on at least one of a physical vibration status, a generation status of noise in signal output, a generation status of optical noise, and a voltage level of a supply voltage in the status notification device; and
a log output unit that outputs a log comprising a monitoring result of at least one of the physical vibration status, the generation status of noise in signal output, the generation status of optical noise, and the voltage level of the supply voltage in the status notification device of the monitoring unit upon a change in the output of the status notification device at least during a normal operation.

2. The status notification device according to claim 1 , wherein
the object is detected by a non-contact sensor.

3. The status notification device according to claim 1 , wherein
the object is detected by a multiple optical axis photoelectric sensor, and
the log output unit outputs the log for identifying a status detected by each of a plurality of light receiving elements of the multiple optical axis photoelectric sensor at a time when the output of the status notification device is changed.

4. The status notification device according to claim 1 , further comprising
a memory unit that stores in advance the log output by the log output unit.

5. The status notification device according to claim 1 , further comprising
a transmission unit that transmits the log output by the log output unit to the outside.

6. The status notification device according to claim 1 , further comprising
an acceptance unit that accepts a user operation and stops the log output unit from outputting the log.

7. A control method for a status notification device, configured to change an output between two values depending on whether an object is detected, the control method for a status notification device comprising:
a monitoring step of monitoring at least one of an operating status of the status notification device and an environment surrounding the status notification device based on at least one of a physical vibration status, a generation status of noise in signal output, a generation status of optical noise, and a voltage level of a supply voltage in the status notification device; and
a log output step of outputting a log comprising a monitoring result of at least one of the physical vibration status, the generation status of noise in signal output, the generation status of optical noise, and the voltage level of the supply voltage in the status notification device of the monitoring step upon a change in the output of the status notification device at least during a normal operation.

8. A non-transitory computer-readable recording medium, having an information processing program recorded therein, the information processing program being for causing a computer to function as the status notification device according to claim 1 , wherein the information processing program is for causing the computer to function as each part of the status notification device.
