Abstract: An apparatus for controlling a menu including an icon display control section for displaying a first icon corresponding to a first function in relation to a second function within a second icon corresponding to the second function. A function control section executes the function corresponding to the icon selected from the first and second icons being displayed.

Abstract: In an optical media monitoring device that detects presence of light-interrupting media between a photoemitter component and a photoreceptor component provided to operate in cooperation with each other, the photoemitter component is driven at a variable level of light emission, and a comparator compares the output of the photoreceptor component with a reference signal which is also variable. The driving means is controlled to cause the photoemitter component to emit a level of light lower than normally used for media detection. Dust degradation of the sensor is determined by checking, in a state of no media present and the reduced light emission of the photoemitter component, whether the output of the photoreceptor component is greater than the reference signal level.
