Abstract
In a contact-type image sensor comprising an array of photosensor elements for receiving light reflected from a document, and a protective layer disposed above the array of photosensor elements for protecting the array of photosensor elements when contact is made with the document, means are provided for discharging electric charges accumulated on the protective layer. This may comprise the protective layer with a relatively low resistivity or a separate conductive layer above or within the protective layer.
