Then, the pen type information, the writing distance information, etc. are read (step (3)). The pen type coded information reading circuit 11 recognizes whether or not the recording pen P has expired in the manufacturing date (step (4)). If the expiration date has passed, a message to that effect is displayed on the status information display unit 13 (step (10)), and the recording pen P is returned to the recording pen storage unit 4a. If not expired, proceed to the next step. The writing distance calculation circuit 12 recognizes whether the effective writing distance when the recording pen P is held in step (2) is smaller than zero (step (5)). If the calculation result is smaller than zero, the fact is displayed on the status information display section 9 (step (11)). Further, based on the information stored in the pen type code storage circuit 13, the pen type coded information determination circuit 11 determines whether or not a recording pen P of the same type exists in the recording pen storage section 4a (step (12)). If there is a recording pen P of the same type, the process proceeds to step. If there is no recording pen P of the same type,
The pen type coded information judgment circuit 11 temporarily stops the X motor and the Y motor via the writing speed / writing pressure setting circuit 14 (step (13)). The description is returned to step (5), and when the writing distance calculation circuit 12 recognizes that the calculation result is larger than zero, the effective writing distance held in step (2) is temporarily stored and the recording pen P is set. It is lowered to draw only one vector (step (6)). The writing distance calculation circuit 12 performs a calculation for subtracting the distance moved for drawing one vector from the temporarily stored effective writing distance (step (7)). Next, it is judged whether or not the drawing is completed (step (8)). If drawing is completed, proceed to step. If drawing is not completed, step (9)
Proceed to. In step (9), it is determined whether or not the recording pen P needs to be replaced for a reason other than the above. If replacement is required, proceed to step. If unnecessary, the process returns to step (5) and the same operation is repeated.

When the process proceeds to step, the recording pen replacement control unit 17
The recording pen P currently held on the pen carriage 2 by
Is returned to the recording pen storage section 4a in the + Y direction shown in FIG. 4 (step (15)). As the operation before returning, the effective writing distance information recorded in the writing distance portion 1b of the recording pen P is erased through the control of the magnetic erasing head 8 of the magnetic head control circuit 10 (step (16)). Continued
Through the control of the magnetic writing head 7 of the magnetic head control circuit 10, the calculation result of the effective writing distance by the writing distance calculation circuit 12 is written in the writing distance recording section 1b of the recording pen P (step (17)). Further, the written information is read under the control of the magnetic read head 6 of the magnetic head control circuit 10 and compared with the above-mentioned calculation result to confirm whether it is correct or not (step (18)). When drawing is completed, a series of operations is completed (step (19)). If there is a pen change in step (9),
If there is a pen of the same type in step (12), proceed to step.
