Abstract

PURPOSE:To close a photosensitive drum cover so as to protect a photosensitive drum from being photosensitized by impact and light from the outside by providing the movable photosensitive drum cover and a rail for moving which guides to move the photosensitive drum cover. CONSTITUTION:The photosensitive drum cover 1 is provided, which is attached to a printer so as to protect the photosensitive drum 5 from the impact and the light from the outside toner than at the time of closing the cover of a printer. The photosensitive drum cover 1 is constituted so as to be opened and closed by the rail 2 for moving the cover. Fixing members 4 are set on both ends of the photosensitive drum cover 1 and fixed by a raised latch 3 at the time of opening and closing the photosensitive drum cover 1. Thus, the photosensitive drum 5 is protected by closing the photosensitive drum cover 1 if necessary.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は電子写真プリンタのドラムカートリッジに関し
、特に電子写真方式プリンタのドラムカートリッジの感
光ドラムを保護する機構に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drum cartridge for an electrophotographic printer, and more particularly to a mechanism for protecting a photosensitive drum of a drum cartridge for an electrophotographic printer.

〔従来の技術〕[Conventional technology]

従来、この種の電子写真プリンタのドラムカートリッジ
はプリンタに装着後、プリンタのカバーを開けた場合、
またはプリンタに装着せず単体で放置した場合、感光ド
ラムが露出したままの構造となっている。Conventionally, when the drum cartridge of this type of electrophotographic printer was installed in the printer and the cover of the printer was opened,
Alternatively, if the printer is left alone without being attached to the printer, the photosensitive drum remains exposed.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

上述した従来の電子写真プリンタのドラムカートリッジ
は、プリンタに装着しプリンタカバーを閉じた時以外、
感光ドラムが露出しているため外部からの衝撃を直接受
ける構造になっており、また長時間光に当てると感光し
てしまうという欠点がある。The drum cartridge of the conventional electrophotographic printer described above is not used when the drum cartridge is installed in the printer and the printer cover is closed.
Since the photosensitive drum is exposed, it is structured to receive direct impact from the outside, and it also has the disadvantage that it becomes sensitive if exposed to light for a long time.

〔課題を解決するための手段〕[Means to solve the problem]

本発明の電子写真プリンタのドラムカートリッジは、感
