Claims

[Scope of utility model registration request]

A fixed pen storage section and a pen holding section of a carriage that can be moved in the X and Y directions are arranged in positions where they can face each other when exchanging pens, and the pen can be taken out and stored by moving the pen holding section. In the pen exchanging device such as an XY plotter, the pen storage section includes a storage section fixing arm, which is biased in the direction of the storage section fixation arm, is capable of holding the pen, and has first and second abutting arms. The pen holder includes a holder fixing arm having a pen locking claw and a holder fixing arm that is biased in the direction of the holder fixing arm to hold the pen. Rotatable holding part rotating arms that can be held and have a protrusion that comes into contact with one of the abutment surfaces at the tip end thereof are provided at different height positions from each arm of the pen storage section, respectively. and when storing the pen, the position of the pen holding part with respect to the pen storage part is shifted toward the holding part fixing arm side by a distance corresponding to the width of the locking claw compared to when the pen is taken out,
When the pen is taken out, the protrusion comes into contact with the first abutting surface and presses the storage section rotating arm, and when the pen is stored, the protrusion comes into contact with the second abutting surface and presses the holding section rotating arm. A pen changing device characterized in that the pen changing device is configured to
