Description

Description: FIELD OF THE INVENTION The present invention relates to improvements in pen stock in XY plotters.

(Prior Art) The configuration of the pen stock portion in the conventional XY plotter is such that the pen holder part of the pen stock and the pen holder side of the pen carriage are movable in response to the movement of the pen holder provided in the pen carriage. The parts are operated relative to each other, and the pen is moved to either one of them and held. A mechanism for lowering the pen cap holder is also provided on the penstock side in order to lower the pen cap and open the pen tip.
As an example, there is a lever type for operating a paint cap as shown in FIG.

(Problems to be Solved) In the pen stock portion 10A having such a configuration, the pen stock is provided between the pen holder 3 and the pen holder 41 on the carriage 40 side.
When the operation piece 42 is delivered, the protruding operation piece 42 attached to the carriage 40 side is brought into contact with the cam 4'attached to the paint cap holder 4, and when the operation piece 42 moves forward, the cam 4'is moved. In order that the paint cap holder 4 can be pushed down via the paint cap holder 4,
The fulcrum 5'is attached to the tip of a lever 5 provided at the rear of the penstock 10A portion as shown in FIG.
Reference numeral 2 is a pen stock frame.

Therefore, a groove 8 is formed on the lower side of the pen stock 10A so as not to hinder the downward movement of the pen cap holder 4.

Therefore, foreign matter easily enters the groove 8 and is difficult to take out once the foreign matter enters the groove 8. If foreign matter enters the groove 8, it will hinder the use of the plotter.

In addition, since the pen cap holder 4 has a structure that rotates with the fulcrum 5'as a reference, there is a drawback that the installation width of the pen stock 10A portion becomes large.

According to the present invention, such a problem is solved so that the pen cap holder in the pen stock portion can be operated in the vertical direction, and a cover for covering the moving space is provided at the bottom of the pen cap holder to prevent foreign matter from the outside. It is an object of the present invention to provide a pen stock in an XY plotter that is configured so that the pen stock portion can be compactly gathered while preventing the entry of the pen stock.

(Means for Solving the Problem) According to the present invention, a recess is provided along one side edge on one end side of a drawing board, and a partition is formed in the recess so that a plurality of spaces are formed along the side edge. A wall is provided, and a pen holder that holds a pen and a pen cap holder that attaches a pen cap are provided above the space, and the pen is held between the pen carriage that holds the pen and the pen holder when drawing. A pen stock for an XY plotter, wherein the pen cap holder is arranged on a seat plate that can be moved up and down with the space formed by the wall and bottom of the recess and the partition wall closed. The seat plate is supported by a compression spring provided at the bottom of the recess, and the seat plate is lowered and retracted at the upper part by pressing from a retracting operation piece attached to the pen carriage. It is a penstock of an XY plotter, which is provided with a cam for avoiding.

(Operation) In the device of the present invention, the seat plate on which the pen cap holder is disposed closes the space formed by the wall and bottom of the recess and the partition wall in conjunction with the movement of the pen carriage. It is designed to move up and down. That is, when the pen is transferred (replacement) between the pen holder and the pen stock of the pen carriage, the retracting operation piece attached to the pen carriage is moved by the forward movement of the pen carriage, and the inclined surface of the cam provided on the upper portion of the pen cap holder Press to retract the pen cap holder downward. At this time,
The seat plate moves downward along the wall of the recess and the partition wall while keeping the space closed. When the seat plate is at the lowest position, the pen is handed over. Next, when the pen carriage is retracted in that state,
The pressing of the cam by the retracting operation piece is released, and the seat plate moves upward along the wall portion of the recess and the partition wall while keeping the space portion closed.

(Effect of the Invention) According to the pen stock of the present invention, since the pen cap holder is configured to move only in the vertical direction and retract from the pen tip during the pen replacement operation, the overall width is narrow. Can be compactly assembled. Further, since the seat plate of the paint cap holder covers the upper surface of the moving space part of the paint cap holder and moves up and down while maintaining its posture, foreign matter enters the moving space part of the paint cap holder. It is possible to prevent this, and there is no problem because foreign matter does not fall into the space.
