A lateral registration adjusting device for use in an optical writing system, such as a laser beam printer, is provided. When a sheet of recording paper has arrived at a registration roller which is driven to rotate intermittently in association with the rotation of a photosensitive drum, a discrepancy between the sheet of recording paper and a reference position in the lateral direction transverse to the direction of transportation of the sheet of recording paper is detected. Based on this information of lateral discrepancy, the writing start position for writing an image on the photosensitive drum in a scan line is adjusted such that the lateral discrepancy is absorbed. Thus, when the image is formed on the drum and then transferred onto the sheet of recording paper, there is obtained a predetermined relative positional relationship between the sheet of recording paper and the image in the lateral direction at all times.

A modular type image forming system includes a laser printer main unit and a plurality of optional units, such as both side processing unit, a large quantity paper feeding unit and a mail box unit, each of which is operatively coupled to said main unit through a commonly usable optical fiber cable through a commonly usable connector. Each unit has its own CPU and serial communications between the CPUs of different units may be carried out through the optical cables. The CPU of the main unit may determine the identity of each of the optional units connected thereto through such communications. The main unit also includes an interface circuit through which the main unit is operatively coupled to each of the optional units. The interface circuit includes a port selector which establishes a connection pattern between the main and optional units in accordance with the identity information of each of the optional units connected. When paper is fed into a transportation path, paper ID is assigned to the paper and retained until the paper is discharged. If the paper is removed from the path without passing a predetermined location, the same image is printed again.

An image forming apparatus includes a charging device for performing charging and discharging using a power storage device, and a plurality of loads each serving as a target of power supply from said charging device and being used in operation of the image forming apparatus. The image forming apparatus obtains information about an operation status of the image forming apparatus and sets priorities for being a target of power supply from the charging device for the plurality of loads, according to the obtained information. The image forming apparatus controls power supply operation of the charging device according to the information about the remaining capacity of the power storage device and the set priorities.

Disclosed is a multi-layer type light emitting device including: at least two light emitting sources disposed to be multi-layered; and an optical surface disposed so as to correspond to each of the light emitting sources excluding one positioned at the rearmost stage for forwardly reflecting rays of light emitted by the light emitting source and transmitting rays of light emitted by the light emitting source disposed at the rear stage. With this device, rays of light emitted by each of the light emitting sources excluding one positioned at the rearmost stage are reflected from the corresponding optical surface and radiated forwardly. In this case, when a different optical surface is disposed on the front stage, the rays of light transmit the optical surface and are radiated to the exterior. In the case where rays of light emitted by the light emitting source positioned on the rearmost stage are radiated forwardly, they transmit the optical surface positioned at the front stage and are radiated to the exterior. Accordingly, rays of light emitted by the multi-layered light emitting sources are radiated from the same plane to the exterior.

A method for making superconductive ceramics laminates comprises forming a thick film of a composite oxide comprising bismuth, strontium, calcium, copper and oxygen on a flat plane of a substrate, and orienting and crystallizing the thus formed film by heat treatment to cause the c-axis of composite oxide crystals to be substantially perpendicular to said flat plane of said substrate. An intermediate layer formed of a noble metal, MgO, SrTiO.sub.3, yttria-stabilized zirconia or an oxide of a superconductive ceramics-constituting element may be interposed between the film and the substrate.
