PURPOSE:To shorten a data transfer time and to improve a recording speed by assigning the remaining output terminals except partial output terminals of the respective output terminal groups of plural shift registers in a control device so that they may correspond to the part of one electrode group in a matrix electrode. CONSTITUTION:As to the respective output terminal groups 29 and 30 of the plural shift registers 25A-25C in the control device, the remaining output terminals 29 except the partial output terminals 30 are assigned to correspond to the part of one electrode group of the matrix electrode. Therefore, waste in the data transfer time of the respective shift registers 25A-25C is reduced. Thus, the data transfer time is shortened as the entire device, and the recording speed of the device is improved. Furthermore, the power consumption of the respective shift registers 25A-25C is reduced and calorific value is decreased. |
