Image forming apparatus
View Patent ↗An image forming apparatus includes an image forming section that forms an image on a recording material, a human detecting device that detects a person including an optical sensing unit that converts only an upward light of incident light to the optical sensing unit to an electric signal, and a controller unit that controls the image forming section based on the electric signal.
1. An image forming apparatus comprising:
an image forming section that forms an image on a recording material;
a human detecting device that detects a person including an optical sensing unit that receives an upward directing light of incident light to the optical sensing unit and that does not receive a downward directing light of incident light to the optical sensing unit; and
a controller unit that controls the image forming section based on the detecting of the human detecting device,
wherein the optical sensing unit includes:
an optical sensor that receives the upward light of the incident light and converts the upward light of the incident light to an electric signal; and
a cover that has an opening positioned in front of the optical sensor, the opening having a shape so that the shape restricts the incident light passing through the opening to only upward directing light, the upward light being a part of the upward directing light.
2. The image forming apparatus according to claim 1 , wherein the cover includes an inclined surface facing downward, and
wherein the opening is located at the inclined surface.
3. The image forming apparatus according to claim 2 , wherein the image forming apparatus further includes a housing member that covers the image forming apparatus, and the cover is a part of the housing member.
4. An image forming apparatus comprising:
an image forming section that forms an image on a recording material;
a human detecting device including an optical sensor that detects a person;
a cover positioned in front of the optical sensor, a part of the cover restricts an incident light passing through the cover so that the optical sensor receives an upward directing light of the incident light; and
a controller unit that controls the image forming section based on the detecting of the human detecting device.
5. An image forming apparatus comprising:
an image forming section that forms an image on a recording material;
a human detecting device that detects a person; and
a controller unit that controls the image forming section based on an electric signal,
wherein the human detecting device includes:
an optical sensor that receives an upward light of an incident light and converts the upward light of the incident light to the electric signal; and
a cover that has an opening positioned in front of the optical sensor, the opening having a shape so that the shape restricts the incident light passing through the opening to an upward directing light, the upward light being a part of the upward directing light.
