ABSTRACT:
A light in weight, hand held device that enables people having low vision capabilities to read small alphanumeric characters. A pin hole lens camera having a long, narrow profile is housed in a housing of the same configuration. A small opening is formed in the leading end of the housing in open communication with the pin hole lens to admit light into the lens. A low intensity light source is positioned immediately adjacent that opening. Roller members are transversely mounted on the leading end of the housing to facilitate displacement of the housing in lateral directions of the type needed to read printed matter. The output of the camera is conductively coupled to a remote monitor and the alphanumeric characters transmitted to the monitor are up to sixty times larger than the original characters. The housing may be adjustably mounted to a support plate so that the user may select the size of the field of view desired, and a rotatably mounted wheel enables adjustment of the focus of the pin hole lens.
