EXPOSURE HEAD AND IMAGE FORMING APPARATUS: abstract simplified (18203105)

• 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. The head includes a substrate and multiple semiconductor chips arranged on it. Each chip has light emitting elements and a drive circuit. There is also a lens array to collect light from the light emitting elements. The drive circuit operates at different potentials than the light emitting elements, and the potential difference between them is equal to or greater than the potential difference between the drive circuit's potentials.

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.
