It is possible to solve the problem that the scroll display mode is not matched with the user operation feeling. An HDD (12) contains a scroll control program for causing a CPU (14) to function as a control unit for varying the scroll panel mode (scroll initial speed Vs₀ and scroll continuation time T) in accordance with the contact coordinate data outputted before contact release at a touch panel (24). In this scroll control program, the scroll initial speed Vs₀ is defined by Expression "Vs₀ = F(Vtc)" using a variation ratio Vtc of the contact coordinate as a variable. On the other hand, the scroll continuation time T is defined by Expression "T = G(L)" using a change amount L of the contact coordinate as a variable.
