Abstract

In an office copier it is often desirable to have an indicator to directly indicate when the end of scan position has been reached without having to open the platen cover. This is accomplished with the device illustrated in the figures without the use of a separate light source or electrical switch. In Figure 1, a light pipe 10 is fixed in the top machine cover 12. When the scanning carriage document lamp 14 is not beneath the light pipe it is shielded from the machine scanning light by a curtain 16 and doesn't light up on the cover. However, as the scanning carriage document lamp 14 is moved to the end of scan position, the deflector 18 in advance of the lamp pushes the curtain against the force of compression spring 22 away from the light pipe, thereby transmitting light to the machine cover as seen in Figure 2.
