PURPOSE:To improve maneuverability by forming a slave display part with touch keys independently of a master display part and executing necessary key entry by said touch keys. CONSTITUTION:The master display part 6, the slave display part 1 and a network control circuit 7 are connected to a body 4 and a telephone line and a telephone set 8 are connected to the circuit 7. The slave display part 1 is provided with an input means 2 and a display means 3 and the input means 2 is constituted of a transparent substance, and when an operator's finger touches a key area displayed on the display means 3, detects the position and informs the detection to a control means 5. In case of executing telephone control, the control means 5 in the body 4 allows the display means 3 to display the push-buttons or the like of the telephone set and controls the circuit 7 based on a detecting signal of the corresponding input means 2. The control means 5 can use an auxiliary application software by using the slave display part 1 independently of the operation of an application software.
