Abstract

In automatic reproducing machines it is desirable to know when the document on the platen has been copied. The figure illustrates a very simple mechanism for doing this in a copier with a scanning optical system so that when the lamp carriage is returned to the home position it is so indicated to the operator. In the figure a document 10 is placed on copying platen glass 14 and the platen cover 12 is lowered on to the top of the document 10 to hold it in position. The document is scanned from the home position to an end of scan position with an optical exposure system including exposure lamp 16 (depicted in the figure at the home position). After scanning the document the exposure lamp which is still energized is returned to the home position. The copier cover has a hole 20 in it and the platen cover also has a hole in it both being placed directly over the home position of the exposure lamp. If desired a rod made of Lucite or similar material may be secured in the hole in the platen cover so that the light from the lamp is transmitted from the hole in the copier cover through the hole in the platen cover.
