Mobile terminal and key operation method capable of restoring operation environment
First Claim
1. A mobile terminal for outputting a desired result by user'"'"'s key operation from an idle screen, said mobile terminal comprising:
- key input storing means for sequentially storing information including the type of a pressed input key as one piece of history data each time for executing the pressed key input; and
restoring means for restoring an operation environment before interrupt based on the history data stored by said key input storing means, when the operation is interrupted before outputting the desired result by executing the key input and the idle screen is undone and then a specific key is pressed.

Abstract
A control circuit sets, as one piece of history data, information including the type of an input key for an operation for inputting data by the key each time of an operation of an arbitrary key from an idle screen, and stores the history data into an operation environment storing unit in a memory. If interrupting the operation for inputting the data by the key due to any processing, an undo key is pressed and then the control circuit sequentially executes the history data stored in the operation environment storing unit in the order of the old history data, thereby restoring a screen just before the interrupt. The operation environment storing unit stores, as one piece of the history data, image data or text data made by the operation for inputting the data by the key.
