本発明は電子プリンタに係り、特に机上の設置面積の小
さい電子写真プリンタに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic printer, and particularly to an electrophotographic printer that requires a small footprint on a desk.

需要が増大している。There has been growing interest in electrophotographic printers, especially in the United States, where their quietness and high performance have been praised, leading to demand as terminal output devices for personal computers (hereinafter referred to as PCs) and word processors (hereinafter referred to as word processors). is increasing.
従来の電子写真プリンタの殆どの機種は記録紙が平置き

写真プリンタ５０を事務机上に配列した一例を示すもの
であるが、これによるとおおよそ記録紙の長さに見合う
寸法ｔと幅寸法Ｗが少なくともプリンタ本体５０の前後
に必要である。In most conventional electrophotographic printers, the recording paper is placed flat, so the installation area of the main body is affected by the size of the recording paper, and this has the disadvantage that it takes up too much space for each individual to install it on their desk. Ta. That is, many conventional printers are configured such that recording paper is mounted on a flat surface and the printed recording paper is sent out from a paper feeding tray provided outside the main body. Figure 4 shows an example in which a personal computer body 42, a cathode ray tube (hereinafter referred to as CRT) 43, a keyboard 41, and a conventional electrophotographic printer 50 are arranged on an office desk. t and width dimension W are required at least at the front and rear of the printer body 50.

示のとおり、一般的な事務机の寸法１０６０ｍｍｘ７１
０６Ｏではプリンタ本体５０によりほぼ机面の右半分を
占有され、メモ書きのための面積は残らなくなってしま
い、甚だ都合が悪かった。Therefore, for example, since the size of legal paper that is frequently used in the United States is 216 mm x 356 mm, an area equivalent to twice the paper length of 356 mm, that is, 216 mm x 712 mm, is required on the desk for recording paper. However, as shown in the diagram, the dimensions of a typical office desk are 1060 mm x 71 mm.
In 06O, the right half of the desk surface was occupied by the printer body 50, leaving no space for writing notes, which was very inconvenient.
また従来の電子写真プリンタでは、記録紙をカセットに
収納し、用紙切れの際はカセットごとプリンタ本体５０
からはずし、カセットに記録紙を装填したのちカセット
を側方よりプリンタ本体５０の側方に余剰空間が必要で
あった。また電子写真プリンタは構造上かなりの重量が
あり、本体の向きを変えるのは困難で、カセット着脱用
の余剰空間も一方向に限定されていた。In addition, in conventional electrophotographic printers, recording paper is stored in a cassette, and when the paper runs out, the cassette and the printer body 50
After removing the cassette from the cassette and loading recording paper into the cassette, an extra space was required on the side of the printer main body 50 from the side of the cassette. Additionally, electrophotographic printers are quite heavy due to their structure, making it difficult to change the orientation of the main body, and the extra space for installing and removing cassettes is limited to one direction.
以上のように従来の電子写真プリンタは、個人用の机上
プリンタとしては設置面積が大きく、記録紙の装填が面
倒で使い勝手が悪いという問題点があった。As described above, conventional electrophotographic printers have problems in that they require a large installation area for personal desktop printers, are troublesome to load recording paper, and are not easy to use.
本発明は上記の問題点を解決するためのもので、記録紙
のセットなどの操作性や机上の設置面積が小さく、使い
勝手の良い電子写真プリンタを提供することを目的とす
る。The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an electrophotographic printer that is easy to use, has easy operation such as setting recording paper, and has a small footprint on a desk.

全中心として水平回動可能のように構成することによっ
て達成される。The above purpose is to provide a recording paper holder on the back of the main unit into which the recording paper is loaded in an upright position.The recording paper after printing is fed along the front of the main unit, and the main unit itself is placed in the center of the lower support stand. This is achieved by configuring it so that it can be rotated horizontally.
