EXPOSURE HEAD AND IMAGE FORMING APPARATUS - A simplified explanation of the abstract
- This abstract for appeared for patent application number 18203105 Titled 'EXPOSURE HEAD AND IMAGE FORMING APPARATUS'
Simplified Explanation
The abstract describes an exposure head used to expose a photosensitive drum. It consists of a substrate, multiple semiconductor chips with light emitting elements and drive circuits arranged on the substrate, and a lens array to collect light from the light emitting elements. The drive circuit operates between two potentials, while the light emitting element operates between two different potentials. The potential difference between the two potentials of the light emitting element is equal to or greater than the potential difference between the two potentials of the drive circuit.
Original Abstract Submitted
An exposure head configured to expose a photosensitive drum includes: a substrate; a plurality of strip-shaped semiconductor chips each including a plurality of light emitting elements that emit light and a drive circuit that drives the light emitting element, the plurality of semiconductor chips being arranged on the substrate; and a lens array configured to collect light from the light emitting elements on the photosensitive drum. The drive circuit operates between a first potential and a second potential, the light emitting element operates between a third potential and a fourth potential, and a potential difference between the third potential and the fourth potential is equal to or larger than a potential difference between the first potential and the second potential.
