Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a color changing device for pen-type multicolor recording devices such as X-Y plotters, drawing machines, and graphic writers using multicolor pens.

Conventional Structure and Problems Conventionally, in a pen-type multicolor recording apparatus, the method shown in FIG. 1 has been common as a method for selecting a pen of a desired color.

In FIG. 1, 1 is a pen holding lever, and when the pressure of a coil spring 2 is normally applied to the movable core 4 of the electromagnetic plunger 3, a force is applied in the direction of the arrow around the support shaft 6.
The pen holder spring 6 is compressed to lift the pen 7 in the direction of the arrow, and the pen tip 9 is separated from the recording paper 8. Furthermore, when the electromagnetic plunger 3 is energized, the movable core 4 compresses the coil spring 2 and moves in the direction indicated by the arrow, so the force in the direction indicated by the arrow about the support shaft 6 that was applied to the pen holder 1 is removed, and the pen holder The pressure of the spring 6 causes the pen 7 to move in the opposite direction to the direction of the arrow, and the pen tip 9 is pressed against the recording paper 8, enabling recording.

In the above configuration, when multicolored pens are attached as shown in FIG. 2, the electromagnetic plunger 3 is arranged corresponding to each pen 7, and only the electromagnetic plunger corresponding to the desired color pen is energized. The pen of the desired color is selected.

Therefore, when there are many types of pen colors, many electromagnetic plungers are required, which has the disadvantage of requiring a large space and increasing costs.

OBJECTS OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks.The purpose of the present invention is to simplify the pen color changing operation of a pen-type multicolor recording device, and to provide a color that allows the device to be miniaturized and manufactured at low cost. This provides a replacement device.

Structure of the Invention In order to achieve the above object, the unreleased F3A is provided with a carriage feeding means for transporting a carriage equipped with a recording pen, and also includes an electromagnetic brush 7, which is used as a child actor to press the pen against the recording paper.・It is configured so that it can be moved to a predetermined position by pressing against a protruding rod attached to the side plate of the Kipanodge transport mechanism, allowing the user to select a pen of a desired color from among a variety of colored pens. .

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 3 is a front view of a pen-type multicolor recording device according to an embodiment of the present invention.

In Fig. 3, reference numeral 10.11 denotes a side plate equipped with protruding rods 12.13, and a carriage 15 equipped with multicolored pens is mounted on a guide shaft 14 fixed between the side plates so as to be slidable in the direction of the arrow X. It is being One end of the belt 16 is fixed to the carriage 16 and rotates forward.

The paper is conveyed in the direction of arrow X by the rotation of a pulley gear 18 fixed to the carriage drive step motor 17 (17a) that performs reverse rotation.

In FIG. 4, a pen 19 mounted on a carriage 16
The pen 22 is moved away from the recording paper 23 because a force is applied in the direction of the arrow by the pen lifting spring 20 via the pen holding lever 21 . Note that the pen holding lever 21 can rotate around a shaft 24. Also, there is a pen holding spring 25 at the top of the pen 19, and when the electromagnetic plunger 26 is excited, the movable core 27 moves in the opposite direction to the direction of the arrow. , the pen holding lever 21 is moved around the support shaft 24 in the opposite direction of the arrow entry direction to compress the pen floating spring 20, and the pen tip 22 is pressed against the recording paper 23 by the bend holding spring 26.

Note that a gap 29 is provided in the carriage 16 so that the electromagnetic plunger 26 can rotate in the direction of arrow B using the protrusion 28 as a fulcrum. Note that normally the spring 3 shown in FIG.
A force in the direction opposite to the direction of arrow B is applied, and the movable core 27 is inserted into the radial groove 32 provided in the bearing 31 shown in FIG.
are fitted and positioned. Further, as shown in FIG. 6, through holes 33, 34 are provided in the side surface of the carriage 15, through which the protruding rods 12, 13 shown in FIG. 3 can pass.

In the above configuration, the electromagnetic plunger 26 selects the second pen from the left end as shown in FIG. 6, and the operation when switching to the third pen from the left end will be described.

As shown in FIG. 2, the step motor 18 is driven so that the carriage 15 moves to the left in the It is rotated in the direction of arrow E using part 28 as a fulcrum. Therefore, the movable core 27 positioned in the radial groove 32 of the bearing 31 by the spring 3o receives a force in the direction of arrow E and moves in the radial groove 32. At this time, the movable core 24 can be moved to any position in the radial groove 32 by controlling the number of pulses applied to the carriage drive step motor 17 and the rotation direction.

The groove 32 is formed in the same position as the pen holding lever 21 arranged corresponding to each color pen, and the movable core 2
By moving the pen 7 to an arbitrary position in the radial groove 32, a desired color of the pen 19 can be selected.

Effects of the Invention As described above, the present invention can provide a color changing device that is inexpensive and takes up a small space because it is not necessary to increase the number of electromagnetic plungers even when there are many types of pen colors.
