JPS6422168A - Handy scanner printer - Google Patents

Abstract

PURPOSE:To save the consumption of a battery by providing a gate to stop a driving clock signal when a handy scanner printer detects the termination of a writing and reading to a flame memory. CONSTITUTION:A clock signal 110 outputted from a transmitter 101 is controlled by a gate 105, and the opening and closing of the gate 105 is executed by a detector 104. When a start signal 111 is inputted to an input terminal 106, the detector 104 opens the gate 105. Thus, a clock signal 110 passes the gate 105, and a driving signal 107 and an address 108 are outputted from a driving circuit 102 and an address counter 103 respectively. When it is detected 104 that the address counter 103 counts up to a prescribed address, the detector 104 closes the gate 105. Thus, the driving circuit 102 and the address counter 103 stop outputs 107 and 108, stop the writing and reading to the flame memory and prevents the wasteful consumption of the battery.
