Abstract: The present invention provides a broadcast receiver having viewing reservation function which, when a viewer is viewing a different program while a program is reserved for viewing, allows the viewer not only to select and switch a program reserved for viewing according to the viewer's judgment but also to select whether the program reserved for viewing or the program that the viewer is currently viewing should be recorded, or to cancel the viewing reservation. Viewing reservation information of a program reserved for viewing is stored in a viewing reservation data storing unit 21 of a main microcomputer 4. If a broadcast starting time reserved for viewing approaches in a state in which the viewer is viewing a program sent from a tuner, a message display unit 24 displays a channel change confirmation message and a recording confirmation message, and the viewer can selectively switch the program that the viewer is currently viewing or the program reserved for viewing according to the viewer's judgment.

Abstract: Extraneous matter such as snow or mud sticking to an ultrasonic sensor is detected. An obstacle (10) reflects transmitted waves from an ultrasonic sensor (3), and the indirect waves (k) are received by an ultrasonic sensor (2), whereby the obstacle (10) is detected. The ultrasonic sensor (3) generates direct waves (t) directly received by the ultrasonic sensors (2) and (4), and therefore the ultrasonic sensors (2) and (4) are arranged to monitor also the direct waves (t). The direct waves (t) are attenuated when extraneous matter (8) such as snow or mud sticks to the ultrasonic sensor (4), and the presence of the extraneous matter is detected according to this attenuation.
