PURPOSE:To execute designation of a chain basing on a simple operation, by displaying in order a stored GRI numerical value when selecting the chain, and operating a switch when a desired display is noticed. CONSTITUTION:When a central operation processor CPU is set to a chain selecting mode by an operation switch CH, one GRI numerical value of storage devices C1, C2,... is displayed on an indicator DP in accordance with a program stored in a fixed storage device ROM. Subsequently, the GRI numerical value of the storage devices C1, C2,... is displayed in order, and when a desired display is noticed, its chain data is provided to the operation processor CPU by operating a switch S. Accordingly, since it is unnecessary to provide a special numerical value setting device, a simple device is obtained. |
