Abstract

PURPOSE: To actuate the arithmetic device stably when the first power source is changed by printing and by driving the arithmetic control device through the second electric source means and connecting the second power source means via a diode having a reverse-current preventing action from the first power source of the printing device.
CONSTITUTION: The second power source means 6 is connected in parallel with the arithemetic control device of the table computer of the printing type having a printing device 4. This power source means 6 is constructed by the capacitor and to the second power source means 6, the terminal voltage V1 of the first power source means 1 is added through the diode 5 using PN connection diode and the like which possesses the reverse-current prevention action so as to be charged. Then, in the case where the printing is not done by the printing device 4, the power source means 6 is charged through the diode 6 and when the printing device 4 begins to character print and the voltage of the power source means 1 is changed, the voltage is fed to the arithmetic control device from the power source means 6 to make the action of the computer stable.
