Abstract

A copying apparatus comprises a document table disposed on the top of a housing and having a glass platen on which an original document is to be laid, the glass platen being movable between a first position to cover the top of the housing and a second position to open the top over the length and breadth thereof, a copying mechanism disposed inside the housing to reproduce on a sheet of copying paper an image of the original document laid on the glass platen, and a protective member attached to the housing for covering the opening of the housing, having openings and being able to move between a third position and a fourth position. The protective member covers the upper portion of the copying mechanism while staying in the third position and the protective member exposes the upper portion of the copying mechanism while staying in the fourth position when the glass platen is in the second position.

Dependent claims

A copying apparatus which comprises:

a housing having an opening at the top;
a document table disposed on the top of the housing and having a glass platen on which an original document is to be laid, said document table being reciprocally movable in one direction between a first position wherein the document table fully covers the top of the housing and a second position wherein the document table partially covers the top of the housing, said document table being pivotal around an axis extending in said one direction between the first position and a third position wherein the top of the housing is fully opened;
a copying mechanism disposed inside said housing to reproduce on a sheet of copying paper an image of the original document laid on the glass platen;
and
a protective member attached to the housing for protecting the copying mechanism, said protective member being pivotal around an axis perpendicular to said one direction between a first closed position wherein the protective member is located over the copying mechanism and a second opened position wherein the protective member fully exposes the copying mechanism when the document table is in the third position, wherein
said protective member includes a single protective cover having a first section located over the copying mechanism and extending substantially horizontally, and second sections hanging severally from both end portions of the first section, a lower end of one of the second sections being pivotally mounted on the housing.
