Abstract
PURPOSE: To prevent the change of an excitation time due to a temperature change and the variation of the speed of a type carrier by reading information memorized after a predetermined time passes and completing the excitation of the electromagnetic magnet by a figure read.
CONSTITUTION: The output (d) of a reset address memory 8 is memorized to a latch 12 at the timing when a CLK1DLY reaches logic "1", and a hammer reset address decoder 6 decodes the output (d) and changes a signal R1 into the logic "1". An effective address decoder 11 decodes a fact that the output (d) is not ineffective data (i) but effective, and turns an effective signal (g) into the logic "1". Accordingly, since HAMRESET, the output of an AND gate 14 reaches the logic "1" at the timing when a CLK 2 reaches the logic "1", an NAND gate opens its gate, and resets a flip-flop. When the flip-flop is reset, a transistor is turned off, and electromagnetism is completed.
