Abstract
An optical writing head which is simplified in construction and reduced in production cost. The optical writing head comprises a light emitting means, and a substrate on which the light emitting means is mounted. The substrate has a light transmitting property at a portion thereof which opposes to the light emitting means. Light emitted from the light emitting means is taken out through the substrate so that it may be irradiated upon a light receiving body. A fiber bundle may be provided with one end opposed to the light emitting means and with the other end opposed to an object for exposure. Where the head is of a type wherein it contacts with an object when it optically writes, the other end of the fiber bundle is formed into a curved face, but where the head is of another type wherein it does not contact with an object when writing, a gas blowing out means is provided to assure a gap between the other end of the fiber bundle and an object. A plurality of flexible printed circuits may be connected to the light emitting means in an opposing relationship to a light emitting portion of the light emitting means.
