A communication apparatus for carrying out communications to and from an external apparatus that includes a first interconnecting unit and a first non-transparent port and effects an interconnection for communications via the first non-transparent port is provided. The communication apparatus includes a second interconnecting unit that includes a second non-transparent port communicably connected to the first non-transparent port. The second interconnecting unit effects an interconnection for communications via the second non-transparent port. The second interconnecting unit performs, when the communication apparatus carries out communications to and from the external apparatus, address translation between an address for use by the communication apparatus and an address for use by the second non-transparent port.

Communication apparatus, communication system and adapter

An optical scanner, including a frame member; a pair of connection members near a coupling end with the frame member; a pair of elastic members connected with the frame member by the connection members; a mirror substrate supported by the pair of elastic members, the mirror substrate having a bending rigidity outward from the rotational axis for each area in accordance with a bending moment caused by oscillation, the mirror substrate having a slit at both connection ends with the pair of elastic members; and a piezoelectric element provided on each of the connection members, the piezoelectric element generating a torque for driving the mirror substrate oscillatable back and forth around the pair of elastic members as a torsion rotational axis.

Optical scanner and image forming apparatus

A disclosed optical scanning device includes a light beam generating unit configured to generate a light beam; a light beam deflecting unit configured to receive the light beam and deflect/emit the light beam with a deflecting mirror; a light beam ON/OFF control unit configured to control the light beam generating unit so that the light beam deflected by the light beam deflecting unit is turned ON/OFF in a particular light beam scanning region while the light beam is being reciprocally scanned; and a light beam scanning time measuring unit configured to obtain a measurement value by measuring a time at which the light beam passes a reference point provided on an edge part of the entire light beam scanning region that is away from a center part of the entire light beam scanning region. Timings at which the light beam is turned ON/OFF are controlled in accordance with the measurement value.

Optical scanning device and image forming apparatus

A supply cartridge contains at least two types of consumable material which are exhausted substantially at the same time over a course of ordinary image reproduction, and the supply cartridge lacks any substantial replacement part so that the supply cartridge replacement wastes no residual life of replacement hardware parts.
