Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a recording device used in an X-Y plotter, a drawing machine, a graph ink writer, etc. using multicolor pens.

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

In FIG. 1, reference numeral 1 denotes a pen holding lever, and normally, when the pressure of a coil spring 2 is applied to the movable core 4 of the electromagnetic plunger 3, force is applied in six directions of arrows around the support shaft δ.
By compressing the pen presser spring 6, the pen 7 is lifted in the six directions of the arrow, and the pen tip 9 is separated from the recording paper 8. Also, when the electromagnetic plunger 3 is energized, the movable core 4 compresses the coil spring 2 and moves in the direction of the arrow, so the force applied to the pen holding lever 1 in the six directions of the arrow around the support shaft 5 is removed, and the pen holder is Due to the elastic force of the spring 6, the pen 7 moves in the direction opposite to the direction of arrow A, and the pen tip 9 is pressed against the recording paper 8.
Recording becomes possible.

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 3 corresponding to the pen of the desired color is energized. By doing so, a pen of a 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.

OBJECT OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks, and its object is to perform the pen color changing operation of a pen-type multicolor recording device by using a rope-like means for conveying a carriage. This makes the device more compact.

The present invention provides a recording device that is lightweight and can be manufactured at low cost.

Structure of the Invention In order to achieve the above object, the present invention provides a carriage equipped with a plurality of recording pens, a rope-like member for transmitting drive of the carriage, an electromagnetic plunger used as a means for pressing the pens against recording paper, and the like. It consists of an electromagnetic clutch part fixed to an electromagnetic plunger, and a pulley forming a part of the electromagnetic clutch part and around which the rope-like member is wound at least once, and the boob is temporarily fixed by electromagnetic force. Then, in accordance with the driving of the rope-like member,
The electromagnetic plunger is moved to a predetermined position to select a pen of a desired color.

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 recording apparatus in an embodiment of the present invention.

In FIG. 3, reference numeral 10.11 denotes a side plate, and a carriage 13 equipped with several pens of different colors is conveyed in the direction of arrow X on a guide shaft 12 fixed therebetween.

In FIG. 4, a pen 17 mounted on a carriage 13
The pen tip 2o receives a force in the arrow input direction from the pen lifting spring 18 via the pen holding lever 19, and the pen tip 2o moves toward the recording paper 21.
away from Note that the pen holding lever 19 can rotate around the support shaft 22.

In addition, there is a pen holding spring 23 on the top of the pen 17, and when the electromagnetic plunger 24 is excited, the movable core 26 moves in the opposite direction to the direction of arrow entry, holding the pen and moving /<-19 around the spindle 22 to enter the arrow entry direction. The pen tip 2o is rotated in the opposite direction to compress the pen lifting spring 18, and the pen tip 2o is pressed against the recording paper 21 by the elastic force of the pen holding spring 23.

The electromagnetic plunger 24 rotates in the direction of arrow B as shown in FIG. 5 around a convex shaft 26 held in a bearing, and forms a radial groove 30 as shown in FIGS. A holding plate 29 made of an elastic body is fixed to the carriage 13 so as to guide the movable core 26 of the electromagnetic plunger. Note that the force of the coil spring 31 causes the electromagnetic plunger 2 to
4 is biased in the direction of arrow C.

Further, an electromagnetic clutch portion 32 is fixed to the electromagnetic plunger≧4 with screws or the like. The electromagnetic multi-latch section 32 includes a yoke 33, an excitation coil 34 therein, and the yoke 33.
It is composed of a pulley shaft 35 which is integrated by caulking or the like, and a pulley 36 which is rotatable around the pulley shaft 36 and around which the rope 14 is wound one or more times as shown in FIG. ing.

The pen color changing operation in the above configuration will be explained.

Normally, when the carriage 13 is driven by the step motor 15, the pulley 36 rotates to the left or right about the pulley shaft 36 in accordance with the movement of the carriage 13. Next, when the color changing operation starts, the excitation coil 34 of the electromagnetic clutch 32 is excited, a magnetic path is formed along the path of the yoke 33, the pulley 36, and the pulley shaft 36, and the pulley 36 is attracted to the yoke 33. , the two are integrated, and rotation of the pulley 36 is prevented. In the above state, when a drive signal is applied to the step motor 15 to move it in the direction indicated by the arrow, the rope 14 on the side wrapped around the pulley moves in the opposite direction to the direction indicated by the arrow, but the pulley 36 rotates in close contact with the yoke 33. Therefore, the electromagnetic clutch portion 22 receives a force in the direction opposite to the direction indicated by the arrow, and the electromagnetic plunger 24, which is formed to move integrally with the electromagnetic clutch 32, receives a rotational force in the direction of the arrow E about the convex shaft 26. receive. Therefore, the movable core, which is positioned by the radial groove 3o of the elastic holding plate 29, receives a force in the direction of arrow E, and as the holding plate 29 is elastically deformed in the direction of arrow C, it moves to another radial groove 30. do. Here, by controlling the signal applied to the step motor 16,
The movable core 26 can be moved and positioned at any position in the radial groove 30. Note that the radial groove 30 is formed in the same width as the pen holding lever 19 arranged corresponding to each color of pen, and by moving the movable core 25 to any position within the radial groove 3°, the desired position can be adjusted. You can choose the color of the pen.

Effects of the Invention As described above, the present invention can be manufactured at low cost because there is no need to increase the number of electromagnetic plungers even when there are many different colors of pens.Furthermore, the carriage can be made lighter and smaller, so the carriage and jig can be made lighter and smaller. This is extremely advantageous when increasing movement speed.
