SENSOR UNIT AND IMAGE FORMING APPARATUS INCLUDING SENSOR UNIT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18331759 titled 'SENSOR UNIT AND IMAGE FORMING APPARATUS INCLUDING SENSOR UNIT
Simplified Explanation
The patent application describes a sensor unit that includes a light-emitting unit, a light-receiving unit, a flag, and a board with a cutout or hole. The light-emitting unit emits light, which is received by the light-receiving unit. The flag can pass through the space between the light-emitting and light-receiving units. The light-emitting and light-receiving units are mounted on the board, facing each other, with the light traveling straight along the board's surface over the cutout or hole. When the flag moves in a direction intersecting the board's surface and enters the cutout or hole, it blocks the light from reaching the light-receiving unit.
- The sensor unit includes a light-emitting unit and a light-receiving unit.
- A flag can pass through the space between the light-emitting and light-receiving units.
- The light-emitting and light-receiving units are mounted on a board with a cutout or hole.
- The light emitted from the light-emitting unit travels straight along the board's surface over the cutout or hole.
- When the flag enters the cutout or hole, it blocks the light from reaching the light-receiving unit.
Potential Applications
- Object detection and tracking systems
- Security systems
- Industrial automation
- Robotics
Problems Solved
- Accurate detection of objects passing through a specific area
- Reliable blocking of light when the flag enters the cutout or hole
Benefits
- Simplified design and construction of sensor units
- Enhanced accuracy and reliability in object detection
- Versatile applications in various industries
Original Abstract Submitted
A sensor unit includes a light-emitting unit including a light-emitting element configured to emit light, a light-receiving unit including a light-receiving element configured to receive the light emitted from the light-emitting element, a flag configured to pass through a space between the light-emitting unit and the light-receiving unit, and a board, wherein a cutout or a hole is formed in the board, wherein the light-emitting unit and the light-receiving unit are mounted on the mounting surface of the board so that the light-emitting element and the light-receiving element face each other, and the light emitted from the light-emitting element travels straight along the mounting surface of the board over the cutout or the hole, and wherein the flag moves in a direction intersecting the mounting surface of the board and enters the cutout or the hole, thereby blocking the light traveling from the light-emitting element to the light-receiving element.
