As shown in Japanese Patent Publication No. 51-39128, this type of device has a position where the bottom surface of the head is in contact with the drawing surface, and a position where the head is at its thickest point, at the connection part between the Y cursor and the head. means for changing the head holding force with respect to an intermediate position between the head and the head; It is known that when the head is below the intermediate position, the lowermost surface of the head is brought into close contact with the drawing surface by its own weight.In the case of the above structure, when the head is held in the raised position, There is a problem in that if a downward external stress is carelessly applied to the head, the head will fall and the head will collide with the surface of the drawing board. Also,
There is a device of this type that is configured to lock the head in the raised position, but in the case of this device, if a load is applied to the head in the opposite direction while the head is locked in the raised position,
Since it was impossible to escape the second load, there was a fear that the elevating link supporting the head would be destroyed.
