PROBLEM TO BE SOLVED: To reuse a performance controlling board 310 mounted with a VDP (Video Display Processor) 314 when replacing a sub liquid crystal 125 for producing a new model.SOLUTION: A CGROM (Character Generator Read Only Memory) 331 stores image data. A second oscillator 902 generates a second operation frequency lower than a first operation frequency generated by a first oscillator 901. The VDP 314 generates drawing data from the image data by use of the first operation frequency to make an image to be displayed on a main liquid crystal 104, and generates drawing data from the image data by use of the second operation frequency to make an image be displayed on the sub liquid crystal 125. The VDP 314 is disposed on the performance controlling board 310. The second oscillator 902 is disposed on a liquid crystal relay board 320. The liquid crystal relay board 320 has a prescribed connection part 903 connecting the second oscillator 902 and the VDP 314, and can be separated from the performance controlling board 310. |
