DOT MATRIX DISPLAY DEVICE

PURPOSE:To input patterns such as arbitrary numerals, characters and symbols and to store the said pattern data, by using a key matrix corresponding, one to one, to the display of a dot matrix display for each one digit for the content. CONSTITUTION:Through the key input of a key matrix (M)1, a position of a display matrix 4 corresponding, one to one, to the key M1 is illuminated. The display data of the display matrix 4 is transferred to a digit of the display section 5 with a key group 2 and a key group 3 can arbitrarily display data of a plurality of digits to the display section 5. The key group 2 stores the display data of the display M4 or the display section 5, allowing to display the data already stored to the display M4 or the display section 5. In the said operating function, an arithmetic control section 8 designates the operation function mode with the input from the key groips 1, 2 and 3 and the function is realized by using an operation circuit 12.
