Abstract
A discharging and light emitting element included in a CIS unit includes a transparent electrode having an external electrode and a substrate having an internal electrode. A first lead is led out from the internal electrode and a second lead is led out from the external electrode, and first and second leads are led out from end portions of the substrate and the transparent electrode at the same side.
Claims2
A contact image sensor unit, comprising:
- a discharging and light emitting element;
- and
- a photoelectric conversion element converting light directed to a manuscript from said discharging and light emitting element and reflected from the manuscript into an electric signal, wherein
- said discharging and light element including a discharge space formed between a first substrate having a first electrode formed inside the discharge space and a second substrate disposed on the first substrate and having a second electrode formed outside the discharge space,
- an insulating layer formed in contact with and over at least part of the first electrode inside the discharge space,
- a first lead portion coupled to said first electrode from a first connection location outside of the discharge space at one side of the discharging and light emitting element,
- a second lead portion coupled to said second electrode at a second connection location not over the discharge space and at the one side of the discharging and light emitting element, and
- said second substrate has a protrusion protruding over said first substrate on which the second connection location is provided and said first connection location is arranged below said protrusion.
