PURPOSE:To clearly discriminate a telephone fee from a residual call time and display them by displaying a telephone fee numercially on a multidigit dot matrix type display and a residual time in analog terms. CONSTITUTION:The telephone fee obtained by multiplaying contents in a call frequency counter by a unit telephone fee (Yen10) is numerically displayed at the right on the 16-digit display, while prescribed characters showing a telephone fee are displayed at the left. Together with displaying a telephone fee a bar with length corresponding to the residual call time is displayed at the left with the aid of appropriate digits. The embodiment uniformly displays a 6-digit numeric if the residual call time exceeds 36 sec. Whenever every five sec decrease in that case, the length of the bar is reduced by one digit from the six digits. If the residual time is 10 sec or below, a message that is written by characters and explains one call time soon will end is displayed. When the residual call time becoms minimal, characters alarms the effect.
