用途の複合機としては技術的に成立たない。The device shown in U.S. Pat. No. 4,241,990 is configured as a reflective type imaging lens of a normal electrophotographic copying device, and its reflective surface is used for both the electrophotographic copying device and the laser printing device. In particular, laser printing devices have complicated structures and are expensive, and are not technically viable as small, low-priced multifunction devices for personal use, for example.

即ち通常の電子写真複写装置と全く別々に小型のプリン
ト装置として半導体発光素子アレイが構成されている。That is, the semiconductor light emitting element array is configured as a small printing device completely separate from a normal electrophotographic copying device.
しかし、空間的配置が構成要素から必然的に決められる

を考慮しなければ目的達成は出来ない。この面からみて
特開昭57−8561のものは、その点の考慮がないた
め小型化には限界がある。However, since the spatial arrangement is inevitably determined by the constituent elements, if you try to construct an ultra-compact composite device that includes a developing unit, photoreceptor drum, etc. as a kit, you will have to consider common optical elements. It cannot be achieved. From this point of view, the method of Japanese Patent Application Laid-open No. 57-8561 does not take this point into account, so there is a limit to miniaturization.

いる点である。The multifunctional device of the present invention is characterized by a cartridge containing a latent image forming and developing means including a photoreceptor drum, a corona discharger, a developer, and a photoreceptor cleaner, and a focusing optical fiber that projects light onto the photoreceptor drum. The focusing optical system selectively selects either the dot signal light for printing generated by the array and the solid-state scanner, such as an optical shutter or a light emitting diode element, arranged in an array that operates on the light from the document and the external information signal. The fiber bundle is provided with an optical light path switching means for guiding the light to the fiber bundle.

It can be attached to and detached from the main body of the apparatus along the guide rail 4'. Reference numeral 6 is a transfer paper sent by a roller. Reference numeral 7 is a printing function device, which includes an optical shutter array 7', a condensing system 7'', It consists of a light source 7''. 8 is a switching mirror. The optical shutter array 7' is, for example, an array of optical shutter elements using liquid crystals that can be switched between transparent and opaque by applying an electric signal. Document table 1, optical shutter array 71
The arrangement relationship between the focusing optical fiber array 3 and the photosensitive drum 5 is such that the reflected light from the document placed on the document table 1 and the light exiting the optical shutter array 7' (in the case of the latter light, The light is reflected by the switching mirror 8), passes through the focusing optical fiber array 3, and forms an image on the surface of the photoreceptor drum 5. The positional relationship between the paper platen 1, the optical shutter array 7', and the photosensitive drum surface (5) is optically conjugate.

The light that has passed through the condensing system 7'' from '' is intermittently converted into an optical dot signal by each optical shutter of the optical shutter array 7'' operated by an external information signal, and this optical dot signal is sent to the switching mirror 8 and the focusing system. The image is formed on the surface of the rotating photoreceptor drum 5 via the optical fiber array 3 to form a corresponding dot latent image (6).The subsequent process is the same as in the case of copying.
