Abstract
A control signal transmitting device is used for a control device, such as a position detecting device. The transmitting device includes a position detecting sensor, and a receiving device situated near the position detecting sensor. The position detecting sensor includes a sensing device, a radio wave transmitting device electrically connected to the sensing device, and a device for directing the radio wave in one direction. The radio wave transmitting device emits radio wave in a direction opposite the sensing device upon receiving a signal from the sensing device. The receiving device includes a radio wave receiving device disposed to face the radio wave transmitting device for receiving the radio wave transmitted from the transmitting device, and a shielding device for covering the receiving device to receive the radio wave from one direction.
