Wrist-mounted optical scanning and pointing systems

摘要

A wrist-mounted terminal for use in electro-optically reading bar code symbols, includes a main body having a display, and a strap for securing the body on and around a wrist of an operator. The terminal includes a detector for detecting light reflected off a symbol. A keypad is mounted on the body for movement between a concealed position in which manually depressible keys are hidden by the body, and an exposed position in which the keys are accessible. The keypad is preferably slidingly received within the body, or hinged to the body.
