发明名称 Alphanumeric display device with keyboard for use with photographic system
摘要 A display device for use with a photographic system that includes a platform for receiving objects to be photographed and a support for a camera used for photographing objects received on the platform. The display device includes a plurality of digit sections arrayed to provide a display of a multiple digit number, a keyboard device for selecting characters to be displayed and an electrical circuit. Each of the digit sections includes a display element having an array of a plurality of segments that are separately actuated in response to predetermined combinations of electrical signals for providing a display of a selected numeric character. The electrical circuit provides the predetermined combinations of electrical signals in response to the operation of the keyboard, and further includes counters for increasing the displayed number by one count in response to a predetermined input signal. The display device may be positioned on the platform when a photograph is made of an object received on the platform to enable the photograph to include both the image of the selected characters displayed by the display device and the image of said object.
