Semiconductor chip for a recording head

摘要

The invention relates to a recording head and apparatus as well as to a semiconductor chip and substrate usable for the recording head. The substrate comprises electrical contacts for external electrical connection in order to receive image signals used for driving recording elements. A logic circuit converts the image signals which are serially supplied to the electrical contacts into parallel signals to be applied to the recording elements via electrical leads. The electrical contacts, the recording elements, the logic circuit, and selectors for selectively driving the recording elements are built in the substrate. The selectors are disposed in a one-to-one relation with the recording elements, corresponding to the interval of the recording elements. <IMAGE>
