Key input device
专利汇可以提供Key input device专利检索，专利查询，专利分析的服务。并且PURPOSE: To reduce misoperation at the time of key input by using a button both as a dial button for a telephone and as a button for numerical data input.
CONSTITUTION: If a hand set 21 is lifted to get an off-hook state, switches SW41 and SW42 in a control part 40 respectively become in the state of connection expressed with a continuous line. By pushing down a dial number from a numerical button 12 in a keyboard part 10, a dial signal is transmitted through a line connection part 50 and a communication line 70 and the call is executed when an opposite side answers. In the case of transmitting data with an automatic dialing from a terminal equipment 60, the telephone transmitter receiver 21 is lifted to be put on a hook switch 13 so as to make the switch 13 actuate. Then the switches 41 and 42 in the control part 40 respectively become in the state of connection expressed with a broken line and by pushing down the specific button in button 12 an automatic dialing state is obtained. And the dial signal corresponding to the specific numerical button is transmitted by the program of the equipment 60 through the communication line 70 and the data transmission is executed when the opposite side answers.
