Abstract
A sensor unit for an electronic device having a pivotable cover member includes a signal emitter, a signal receiver spaced from the signal emitter, and a baffle attached to the cover member and disposed in the space between the signal emitter and the signal receiver when the cover is in its closed position. A transmit window disposed between the signal emitter and the signal receiver is permeable to signals falling within a specified wavelength range, thereby ensuring the accuracy of the signal. When the sensor unit is applied to a cellular phone, for example, the phone can be automatically in an 'off hook' or 'on hook' condition automatically in accordance with whether the cover member is in its open position or closed position, and an operator need only perform a single operation to answer or terminate a call or to power up the phone.
