To provide an apparatus and a method for recording a time capable of realizing an automatic control of an applied pressure to a material to be time recorded, shortening a time taken when lines to be time recorded are not connected or when the material is moved between characters to be time recorded and shortening the overall time recording time.
A speed of reciprocating motion of a pen is controlled by controlling a rotating speed of a motor 1a so that an output of a tachometer 1a' is maintained at a value previously set in a pulse duty setter 21a, and an output of an amplifier 29 is compared with a value previously set in a torque setter 21c to sense a contact of the pin with the material to be time recorded. A pressure to be applied of the pen to the material to be time recorded is controlled by controlling a torque of the motor 1a so that the output of the amplifier 29 is maintained at a value previously set in a pulse duty setter 21b. Further, a pulse switch 33 is switched by an applied pressure switching signal 32, the torque of the motor 1a is controlled so that the output of the amplifier 29 is maintained at a value previously set in a pulse duty setter 30. Thus, the pen does not almost apply a force to a processing surface.
