PURPOSE:To rationalize jobs for production and installation with a stock price display device by writing previously the initialization information on a display means into an external memory and storing said information into a memory contained in the display device from the external memory. CONSTITUTION:The various initialization information necessary for the display control of a display board 4 are written into an external memory 13 via a writing device and stored regardless of the production of the board 4, etc. Then the memory 13 is connected to a controller 1a when the board 4 is forwarded or installed after its carry-in job. Thus the initialization information are written into a RAM in a control part 11. As a result, no limitation is given to the writing jobs of those initialization information on the board 4. In addition, the information can be easily written again from the memory 13 even though the information written once into the RAM of the part 11 are erased. Thus the jobs for production and installation can be rationalized with a stock price display device. |
