Abstract
Provided is a recording head substrate on which are mounted energy generating elements that contribute to the formation of images by a recording head, and on which both light-receiving elements and light-emitting elements, or at least, light-receiving elements are mounted. In addition, provided is a recording head substrate on which are mounted energy generating elements that contribute to the formation of images by a recording head, and on which are mounted a plurality of head position detecting elements for detecting the position of the recording head.
Claims48
A recording head substrate provided with an energy generating element that contributes to the formation of an image in a recording head for forming an image,
- wherein a light-receiving element is formed in a same substrate as said recording head substrate.
A recording head substrate provided with an energy generating element that contributes to the formation of an image in a recording head for forming an image, wherein a light-receiving element and a light-emitting element are formed in a same substrate as said recording head substrate.
A recording head substrate provided with an energy generating element that contributes to the formation of an image in a recording head for forming an image, wherein a plurality of head position detecting elements for detecting the position of said recording head is formed in a same substrate as said recording head substrate.
A recording head for forming an image using an energy generating element, wherein
- a head position detecting element for detecting the position of said recording head is formed in a same substrate as a substrate provided with said energy generating element.
A recording apparatus provided with a recording head for forming an image employing an energy generating element while moving on a line, the recording apparatus comprising:
- a head position detecting element that are provided to said recording head for detecting the position of said recording head;
- and
- a detected member of said head position detecting element, opposed to said head position detecting element and fixed to a main body of the recording apparatus along a track where said recording head moves.
A recording method comprising the steps of:
- calculating data from a head position detecting element and image recording data by an operating circuit;
- and
- applying a drive signal to energy generating elements at a timing based on the result obtained by said calculating step.
