Claim Text:
1. A display device for displaying on a screen an operation of a control target device which is operated by an input of a command value of a position outputted by execution of a control program in a predefined period, as a moving image of a virtual mechanism, the virtual mechanism being an electronically constructed three-dimensional model, the device comprising: a plurality of functional sections, running on at least one processor, including: a virtual mechanism presenting section configured for presenting options of a virtual mechanism on the screen; a virtual mechanism accepting section configured for accepting one selection of the virtual mechanism out of the options of the virtual mechanism presented by the virtual mechanism presenting section; an acquirement section configured for acquiring command values of a sequence of positions or actual measured values of a sequence of positions as execution results of the control program; a moving image data creating section configured for creating moving image data showing a state of the selected virtual mechanism in every period or in a plurality of predefined periods by use of the acquired command values of the positions or the actual measured values of the positions; and a display controlling section configured for displaying a moving image on the screen by use of the moving image data, wherein the virtual mechanism includes a structure in which a plurality of mechanism elements are combined having interlocking relationships, the virtual mechanism presenting section presents at least a plurality of options of virtual mechanisms which are mutually different in kind of the mechanism element or in form of the interlocking relationship among the mechanism elements, and the virtual mechanism includes an abstracted mode not imitating a mode of a specific control target device that can be associated with the virtual mechanism when the virtual mechanism is used by a user, wherein the virtual mechanism presenting section presents at least options of a virtual mechanism having a linear moving element as the mechanism element, the linear moving element has a columnar linear moving shaft and a movable section that moves along the linear moving shaft, and the linear moving element is displayed in a mode where a length of the linear moving shaft remains unchanged from the beginning to the end of reproduction of at least one moving image.
