Abstract: There is provided a communication apparatus including a plurality of radio transmitter sections, which is capable of suppressing unnecessary radiowaves from being generated due to mutual modulation distortion without increasing the size and weight of the whole apparatus. When the communication apparatus receives a signal from a radio base station and it coincides with the ID of a station when one transmitter section is operative, it rejects a process for the incoming call request. Therefore, no transmission is made simultaneously by the different radio transmitter sections, and the quality of the radiowaves transmitted may be kept high.

Abstract: An input apparatus is capable of recognizing an order of selection of a plurality of options displayed in a display region. The input apparatus includes a display unit having the display region with a predetermined coordinate system set thereto, an operating unit including a select key assigned to a direction parallel to one reference axis set in the display region, and a display control unit. The display control unit first causes a predetermined number of options to be displayed in the display region in such an arrangement that predetermined reference points within the options do not have overlapping coordinates in the direction parallel to the reference axis, and that the options form a plurality of rows and a plurality of columns. Then, the display control unit selects one of the options. When the select key of the operating unit is operated by a user, the one option is changed according to the order of selection in response to the key operation.
