<p>PURPOSE:To display a picture plane without inputting a picture number by storing a picture plane retrieving data group for specifying the picture plane number, selecting that which coincides with an input data from in said group, and displaying a corresponding picture plane data. CONSTITUTION:A key input device 1 is provided with an up key of the number of stages 2, a down key 3 of the number of stages, each direction shifting right and left key 4, 5, a stage number key 6, direction key 7, equipment key 8 and a control key 9; and a data for specifying a picture plane number is stored in advance as a picture plane retrieving data group in a memory 19. Subsequently, a picture plane retrieving data of a stage, direction, etc. inputted from the device 1 is compared with the data of the memory 19 by a comparing means 20; a data which has coincided with each other is selected, and a picture plane number assigned to said data is outputted to a read-out means 21. Next, a picture plane data corresponding to its number is fetched from a picture data memory 14 by the means 21 and displayed on a CRT indicator 16.</p> |
