PURPOSE:To facilitate data correction and to make it possible to generate even several kinds of patterns without increasing data memory parts by enabling video fabrication by data fabricated in an external calculator, by constituting a data memory part from RAM while adding a calculator interface. CONSTITUTION:A data memory part 3 is constituted of RAM and informations for showing data for fabricating an address table and video and the completion of data are inputted from an external calculator. When a data transmission demand signal 59 is outputted from this apparatus or an external calculator side, a control part 5 puts in operation for writing data in the data memory part 3 and data inputted to a calculator interface part 8 from the external calculator by a transmission bus line 58 is written in the data memory part 3. When information for showing the completion of data is inputted, the control part 5 enters operation for fabricating video. As mentioned above, because data from the external calculator can be used by adding the calculator interface part, the fabrication or correction of data can be performed by the external calculator and becomes extremely easy. |
