Abstract
An information processing device that can use two different functions for returning an initial screen and a preceding state by a simple method, a control method of the same device and a recording medium for recording a control program for the same device are provided. An information processing device having an initial screen including an initial image presentable after turning on a power supply and having a returning means for returning from a current screen state to a preceding screen state or returning from any screen state to the initial screen, wherein it is provided with a key-operation counting portion for counting the number-of-operations of a specific key, a reference storage portion for storing the reference number-of-operations of the specific key, a comparison portion for comparing the number of operations counted by the key-operation counting portion with the reference value stored in the reference storage portion, and a control means for driving the returning means according to the comparison result in such a way that the returning means executes its function for returning to the initial screen state when the counted number matches the reference number and the returning means executes its function for returning to a preceding screen state when the counted number does not match the reference number.
