PURPOSE:To totalize sales data only in an in-use time zone by time zones, by storing time-zone specification data and by specifying a time-zone storage means, except a disuse time zone, corresponding to the in-use time zone. CONSTITUTION:An input part 1 is equipped with a time key for inputting time- zone data for totalization by time zones, and a void key for inputting disuse time-zone data. The input part 1 is supplied with a timing signal KP from an I/O port 2 and when keying operation is done at the input part 1, the timing signal KP is selected and inputted as a key input signal KI to an input buffer IB equipped to the I/O port 2. In the I/O port 2, a display buffer HB and a print buffer PB are equipped in addition to the input buffer IB; and the display buffer HB is connected to a display part 3, and the print buffer PB is connected to a print part 4 respectively. |
