1. An operating device connected to an operation controller of a NC machine tool for inputting an operation signal into the operation controller, comprising:
a touch panel including a display unit for displaying a screen and an input unit which is disposed in a state of being overlapped on the display unit for inputting data relating to a position touched by an operator, the display unit being visually recognized from outside; a display screen data storage unit storing therein data relating to display screens to be displayed on the display unit of the touch panel, the display screen data storage unit storing therein at least data relating to a mode switching screen for selecting one from a plurality of operation modes and data relating to a plurality of operation screens for inputting operations corresponding to each of the operation modes; an operation information storage unit storing therein operation information which is defined in correspondence to a position on the display screen for each of the display screens; an attribute information storage unit storing therein attribute information which is set for at least a part of the operation screens set for each of the operations modes and which defines a relationship between each of the operation screens and its corresponding operation mode; a display control unit which sets at least two display areas of a mode switching screen display area and an operation screen display area with respect to the display unit of the touch panel, reads out the display screen data stored in the display screen data storage unit, and displays the mode switching screen and the operation screens in the mode switching screen display area and the operation screen display area, respectively; and an input signal processing unit which performs a processing of receiving a signal input from the input unit of the touch panel, referring to the operation information stored in the operation information storage unit based on the received signal, generating an operation signal corresponding to the received signal, and transmitting the generated operation signal to the operation controller, and, when it is necessary to change the display screen, a processing of generating a display screen changing signal and transmitting the generated display screen changing signal to the display control unit, the display control unit further being configured to receive the display screen changing signal from the input signal processing unit and change the display screen displayed on the display unit of the touch panel in response to the signal, and wherein the operating device further comprises an automatic mode switching unit which monitors the display of the operation screens by the display control unit and determines whether the attribute information is set for the displayed operation screens or not by referring to the attribute information stored in the attribute information storage unit, and in a case where the attribute information is set for the displayed operation screens, generates a mode switching signal for switching to a corresponding operation mode and outputs the generated mode switching signal to the operation controller.
