Abstract:
1. A control device for use in an injection molding machine that melts synthetic resin material and injects a predetermined amount of molten synthetic resin material into a metal mold to obtain a molded product, comprising: a display section in which a touch panel is disposed on a display screen; and a human-machine interface section equipped with a general-purpose operating system, the human-machine interface section being provided with at least a storage section to store set values which are various molding conditions for each mold article and a control section which controls the display of the display section, the human-machine interface section displaying, on the display section, a main screen to chance settings for the molding conditions stored in the storage section and a subscreen to display indications such as monitors, and also constantly displaying a change switch for a change of the screen in a fixed region of the display section, wherein the human-machine interface section includes: a buffer memory which temporarily stores the set value; means for opening a setting window having a copy button when a set value display region displayed in the display section is touched; means for temporarily storing, in the buffer memory, the set value displayed in the setting window when the copy button provided in the opened setting window is touched; and means for copying the set value stored in the buffer memory as the set value in the set value display region to be touched next when the set value display region is touched in a case where the unit of the set value in the set value display region to be touched next is the same as the unit of the set value stored in the buffer memory and where the set value stored in the buffer memory is within an allowable range of the set value in the set value display region to be touched next.
