PURPOSE:To realize an easy and quick input, alternation, etc. for a dot matrix pattern, by providing a pattern input/display board in which the cells are arrayed in a matrix form plus a means to transfer the input pattern to an upper device. CONSTITUTION:In a pattern input/display board 100, cells S in which a switch and an indicator are set opposite to each other are arrayed in a matrix form. At the same time, a means is added to give the drive control to the indicator of a corresponding cell S by a switch operation of an optional cell S. Furthermore a means is provided to transfer the input pattern displayed in a matrix form by the indicator to an upper device of a CPU, etc. For instance, the pattern data following the switch operation is written into a pattern memory 40 under the control of a controller 30. This data is then read to light up the corresponding LED and at the same time transferred to the CPU via an input/output part 70. |
