In order to allow an advertisement company to register advertisement information using the Internet and conduct publicity activities aimed at specified target users, profile data of a plurality of users is managed using a database, selection conditions for selecting specific users to whom advertisement information should be distributed are received, specific users to whom the advertisement information should be distributed are selected based on the received selection conditions and the managed profile data, and the advertisement information is distributed to the selected specific users utilizing a digital broadcasting system.

Information distributing method and information distributing system

A laser recording apparatus includes a laser optical unit having an integral combination of a laser for emitting a laser beam and an optical system for converting the laser beam into an expanded and collimated beam; a deflector unit for directly receiving the laser beam emergent from the laser optical unit and directing the laser beam toward a recording medium; a photoreceptor unit having an integral combination of a reflecting member for reflecting the laser beam deflected by the deflector unit and a photoreceptor for receiving the laser beam reflected by the reflecting member; a support member having standard portions respectively for mounting the laser optical unit, the deflector unit and the photoreceptor unit.

Laser recording apparatus

In an image information recording apparatus which comprises a laser oscillator, means for deflecting and modulating the laser beam from the laser oscillator by an external signal, a recording medium, optical means for imaging the modulated laser beam on the recording medium and means for causing the laser beam to scan over the recording medium, the light path of the laser beam is divided into a plurality of light path sections and partition plates are provided before and behind each of the light path sections and have holes formed at the portions thereof corresponding to the center of the optical axis. Thus, the optical axis in the apparatus may be adjusted by passing the laser beam through the center of the holes in the partition plates.
