Educational device for learning geographical names and locations

Abstract

Abstract An educational device for use in learning the locations and names of the various states in the United States as well as other information pertinent to each state is disclosed. The device comprises a rectangularly shaped board having a map of the United States on its front surface, a plurality of lamps mounted on the board, one lamp within the boundary of each state and preferably at the state capitol, a battery holder containing a battery, a cartridge receptacle mounted on the board and arranged to selectively connect the battery to each lamp, and a plurality of cartridges adapted to be inserted into the receptacle one at a time to electrically connect one of the lamps to the battery. Each cartridge contains printed matter pertinent to its particular state and is made of translucent material. When inserted into the receptacle, the cartridge is illuminated by a lamp mounted on the bottom of the receptacle and connected to the battery so that the printed matter can be easily read. In one embodiment the receptacle comprises a female card-edge connector having a plurality of pairs of contacts, one contact in each pair connected to the battery and the other contact connected to a different lamp. The cartridge contains a mating male card-edge connector. In another embodiment the receptacle includes a row of microswitches and the cartridges each include a differently positioned button for closing a different microswitch when it is inserted into the receptacle.
