Abstract

[Structure] A mobile phone (10) includes a touch panel (38) and a touch control circuit (36) detecting a touch operation, and can set a lock state that a telephone function or the like is restricted. If the lock state is set and a key operation is performed, a message urging to long-depress a touch is displayed on a display (30), and when the touch is detected, a changing object representing an elapse of time is displayed on the display (30). If five (5) seconds elapse in a touched state, a completion image is displayed on the display (30). Then, if a finger is released from the touch panel (38) within three (3) seconds after the completion image is displayed, the lock state is canceled.

Claims

1. A portable terminal having a touch panel and a touch operation detecting portion which detects a touch operation and capable of setting a lock state where predetermined processing based on a touch detected by the touch operation detecting portion is not performed, comprising:

a displaying portion which performs displaying of an object for canceling the lock state when the lock state is set;

a determining portion which determines whether or not a touch operation by which the object is changed to predetermined displaying is performed with respect to the object; and

a canceling portion which cancels the lock state when it is determined by the determining portion that the touch operation by which the object is changed to the predetermined displaying is performed,

wherein the determining portion includes a second determining portion which determines whether or not the touch operation intersecting with the object is performed to the touch panel,

wherein the canceling portion includes a second canceling portion which cancels the lock state when it is determined that the touch operation intersecting with the object is performed to the touch panel by the second determining portion,

wherein the object is defined by a first function and a second function,

wherein the second determining portion includes a third determining portion which determines whether or not the first function is established by coordinates indicated by the touch operation intersecting with the object to the touch panel and a fourth determining portion which determines whether or not the second function is established by coordinates indicated by the touch operation intersecting with the object to the touch panel, and

wherein the second canceling portion cancels the lock state when it is determined that the second function is established by the coordinates indicated by the touch operation intersecting with the object to the touch panel by the fourth determining portion after it is determined that the first function is established by the coordinates indicated by the touch operation intersecting with the object to the touch panel by the third determining portion.

2. A mobile terminal according to claim 1, further comprising a first changing portion which changes the object to a first displaying state when it is determined that the first function is established by the coordinates indicated by the touch operation intersecting with the object to the touch panel by the third determining portion.

3. A mobile terminal according to claim 2, further comprising a second changing portion which changes the object to a second displaying state when it is determined that the second function is established by the coordinates indicated by the touch operation intersecting with the object to the touch panel by the fourth determining portion.
