A WATCH OF PATROL TYPE WHICH CONSISTS OF ELECTRONICS CIRCUITS

摘要

The watch prints the information memorized in the patrol course and time. The watch includes phototransistors (Q1-Q4) for receiving infrared signals from a photodiode housed in each of patrol boxes, a CPU (4) for storing position data memorized at a EP rom (6) and time data of timer (5) in a ram (7), a control circuit (10) comprising a EP rom (6) to control operation of CPU (4) by a program, a printer (15) and display circuit (20) for printing or displaying the position and time data stored in the ram (7).
