Abstract:
An information processing device having an initial screen presentable just after turning on a power supply and as necessary thereafter and having a preceding-state returning means for executing, after transition of a screen state from one to another, a procedure for returning from a current screen state to a preceding screen state and an initial-state returning means for executing a procedure for returning from any screen state to an initial screen state, wherein it is provided with a key-operation counting means for counting the number of successive operations of a specific key, a reference storage means for storing the reference number of operations to be successively made on the specific key, said reference number being necessary for starting the initial-state returning function, a comparison means for comparing the number of operations counted by the key-operation counting means with the reference number stored in the reference storage means, and a control means for driving, according to the comparison result, the initial-state returning means when the counted number matches the reference number and the preceding-state returning means when the counted number does not match the reference number.
