PURPOSE:To perform clean recording by using the constitution wherein resistors which are connected to a capacitor forming an input filter circuit are changed and the scanning speed of a pen is changed, thereby suppressing the effluence of ink. CONSTITUTION:A switching mechanism 11 can change the resistors 12 and 13 which are connected to the capacitor 14. An input signal (a) is applied to a servo motor 4 through the input filter circuit 1 which is provided with the switching mechanism 11, a preamplifier 2, and a power amplifier 3. The recording (b) is performed by the output of the motor through a speed reducing mechanism 5 and a pen mechanism 6. The running speed of the pen can be changed by the changed of the resistors 12 and 13. Therefore the amount of the offluence of the ink is suppressed in the sampling recording, and the clean recording can be performed. |
