PROBLEM TO BE SOLVED: To enjoy a bingo game alone. SOLUTION: This handy bingo machine whose prerequisite is handiness is formed into a rectangular column rotating three rows and three columns of bingo cards and withstands the repetitive use. This handy bingo machine employs a rotary plate instead of a bingo ball and selects a division mark by its agreement with the indicator provided in a body. Pictures which are more intelligible than the letters and numbers are used for the machine for the infant. COPYRIGHT: (C)2004,JPO&NCIPI
