PURPOSE: A touch scroll device is provided to reduce the number of touch sensors for performing a scrolling function and to receive an operation instruction from a user. CONSTITUTION: A touch scroll device comprises touch keys(11,12,13,14,15,16), touch sensors(21,22,23), and a controller(30). The touch sensor detects contact between two or more touch keys. The controller controls a scrolling function based on a sensing result from the touch sensors. |
