发明名称 COMMUNICATION TERMINAL EQUIPMENT
摘要 PROBLEM TO BE SOLVED: To connect the terminal equipment to a telephone line at the end of communication without being affected by a voltage drop of a battery with a simple configuration. SOLUTION: The terminal equipment is provided with a 1st capacitor 26 to drive a rest coil to connect a telephone set 1 and a telephone line 2 to a latching relay 7 and a 2nd capacitor 25 to drive a set coil 9 to disconnect the telephone set 1 from the telephone line 2 separately. At start of communication, a voltage across the capacitor 25 is applied to the set coil 9 and the 1st capacitor 26 holding the voltage without being affected by the voltage drop of the battery 13 during communication applies a voltage to the reset coil 10, which is driven.
