PROBLEM TO BE SOLVED: To reduce cost and power consumption and to improve facility of seeing the display of rise and fall by displaying the color of a data display screen in red when stock price fluctuation rises higher than the set value and in green when it falls in correspondence with the rise and fall of stock prices. SOLUTION: A rise and fall lamp of a stock display part 71 is disused, and each data display screen 73 of a data display part 72 is composed of a display element changeable into red and green. In the data display part 72, the color of the data display screen 73 with data display characters 64 arranged to display data stock by stock is displayed in red when stock price fluctuation rises higher than the set value and in green when it falls in correspondence with the rise and fall of stock prices. The color change of the display screen 73 is controlled by a signal of a conventional rise and fall lamp. It can also be so constituted that a data frame is provided around the data display screen 73 and that the color of the data frame part is changed into red or green in correspondence with rise and fall. The cost of a device and power consumption can therefore be reduced in comparison to a conventional device, and facility of seeing the display of rise and fall can be improved. |
