Abstract

The printwheel setting apparatus is used in a postage meter for setting the posting date printwheels. Each settable member of the apparatus includes digital encoding marks thereon. A charge coupled device is arranged to detect the encoding marks of one or more settable members simultaneously. A lens is disposed between the settable member and the charge coupled device to focus the image of the encoding marks onto the surface of the charge coupled device. Thus, the settings of a number of settable members such as thumbwheels may be determined simultaneously. A shutter may be closed across the charge coupled device to protect it from damage, dust contamination.
