The stopper (50) is biased toward the blocking position and displaces to the nonblocking position in response to a manual opening operation for displacing the lid to the open position.

Abstract: A high frequency receiver capable of stably canceling interference by a transmission signal even if a transmission signal input from a TV antenna is changed. Phase shifter (212) for changing a phase of an interfering distributed transmission signal, detector (216) for detecting a level of a transmission signal included in a receive signal input via an antenna, and level regulator (213) for changing a level of the distributed transmission signal in accordance with this level are provided. A signal input via level regulator (213) and phase shifter (212) and a receive signal are synthesized to be input into mixer (206). Since a transmission signal can be cancelled even if a transmission signal input from an antenna is changed, a high frequency receiver can receive a signal stably when a transmission signal is changed.

Abstract: A high-frequency receiver and a portable device using the same receiver are proposed for reducing power consumption. Image interference determiner (44) determines whether or not image interference exists at the present position in a desirable channel to be received, which channel is obtained by a receiving section (39) or a GPS receiver (43). Power supply control circuit (47) switches mixer (49) from an image rejection mixer to a double balance mixer when determiner (44) determines no image interference involves. This mechanism allows mixer (49) to work as the double balance mixer circuit during the reception of channels free from image interference, so that a mixer consuming less power is achievable. When mixer (49) works as the image rejection mixer circuit, image interference can be reduced.
