PROBLEM TO BE SOLVED: To provide a locked function releasing apparatus for a display and construction equipment, which facilitates release of a function locking state of the display without using a special tool for releasing even if an authorized user forgets a PIN number (operating pattern) for releasing the function locking state of the display such as a monitor panel, thereby changing a display screen to a next one, and facilitates release of the function locking state of the display without using a special tool for releasing the locking, even if the authorized user of the construction equipment forgets a PIN number (operating pattern) for releasing the locking state of a starting function or an operating function. SOLUTION: A plurality of setting operating patterns which are different from each other are set in storage sections 16a and 16b. When an operating pattern input by input means 3 to 15 corresponds to one of the setting operating patterns set in the storage sections, the display screen 2 of the display 1 is permitted to be changed to the next screen 100, to thereby release the locking state of the starting function or operating function of the construction equipment. |
