Abstract
Three independent dialing buttons (10, 20 and 30) have rhombic shapes. Independent switching elements (S1)-(S4) are provided on four corners of the rear surface of each dialing button. Dial numbers (1-9 and 0) and symbols (# and *), grouped four each as (1, 2, 3 and 4), (5, 6, 7 and 8) and (9, 0, # and *), are marked on the respective four corners of the front surfaces of the three dialing buttons which are arranged longitudinally on an operation surface (50). By this construction, the visibility and recognizability of numbers, etc. can be improved and, further, dialing of numbers can be accurately made.
