Abstract

PURPOSE: To make it possible to operate a reader over a look at a display device, by displaying on a display device the status of the memory amount of certain information which is being stored in a memory.
CONSTITUTION: Memory unit M consists of memory Mm of (m) by (n) bits, m- scale X address counter Cs, and Y address counter Cy whose count value increases by one every time the count value of Cx reaches (m). An address signal supplied from Y address counter Cy to memory Mm is supplied to display device counter Ci as well and display device counter Ci counts the advance number of Y address counter Cy and, every time its count value reaches a fixed numeral, sends a pulse to the display device driver. The display unit driver consists of flip-flop and transistors and operates display device composed of light emission diodes Pd to display the memory status of the memory on the display device.
