JPS6054854A - Color exchanger for pen-type multi-color recorder - Google Patents

Abstract

PURPOSE:To obtain a small space of color exchanger by using a system in which a gear engaged with a belt for driving a carriage and an electromagnetic plunger to press a pen on a recording paper are temporarily fixed, and the pen of a desired color is selected. CONSTITUTION:When an electromagnetic plunger 32 for triggering is excited, a spring 35 is compressed by a movable core 33, and the tip is fit with a gear 39 to be engaged with a belt 36. Under the condition, when a carriage 13 is about to move by a pulse motor 15, the gear 39 and a plate metal 34 are turned by reverse movement of the belt 36 not fixed to the carriage, the plunger 24 is turned at a projection 27 as a supporting point, and the movable core 25 positioned by the spring 29 at the radial groove 31 of the bearing 30 is turned in the direction of E and moved along the groove 31. By controlling pulse number to be applied to the pulse motor 15 for driving carriage, the pen 17 of desired color can be selected. The color exchanger of a small space can thus be obtained without increasing the number of the electromagnetic plunger.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a pen-type multicolor recording device such as an X-Y block device, a drafting machine, a graphic writer, etc., which uses 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, reference numeral 1 denotes a pen holding lever. Normally, when the pressure of a coil spring 2 is applied to the movable core 4 of an electromagnetic plunger 3, a force is applied in the direction of the arrow about the support shaft 6, and the pen is The pen 7 is lifted in the direction of the arrow by compressing the presser spring 6, and the pen/tip 9 is separated from the recording paper 8. Furthermore, when the electromagnetic granger 3 is energized, the movable core 4 compresses the coil spring 2 and moves in the direction of the arrow, so the force in the direction of the arrow about the support shaft 5 that was applied to the pen holding lever 1 disappears.
The pen 7 moves in the opposite direction to the direction of arrow entry due to the pressure of the pen presser spring 6, and the pen tip 9 is pressed against the recording paper 8, resulting in five-fold 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, and an object of the present invention is to change the pen color of a pen-type multicolor recording device by using a belt for conveying the carriage. The present invention provides a color changing device that can be miniaturized and manufactured at low cost.

Structure of the Invention In order to quickly achieve the above object, the present invention provides a carriage feeding means for transporting a carriage equipped with a recording pen, and also includes a gear meshed with a belt used for drive transmission, and a gear that presses the pen against the recording paper. By providing a mechanism for temporarily fixing the electromagnetic plunger used as a means, it is possible to move the electromagnetic plunger to a predetermined position and select a pen of a desired color from among multicolored pens. It is composed of

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, 1o・, 1□ are the side plates. On a guide shaft 12 fixed therebetween, a keypad 13 equipped with multicolored pens is mounted so as to be slidable in the direction of arrow X.

Note that one side of a belt 14 is fixed to this carriage 13, and a pulse motor 1 for driving the carriage rotates forward and reverse.
It is conveyed in the direction of the arrow X by a pulley gear fixed to the shaft 5 by 160 rotations.

In FIG. 4, a pen 17 mounted on a carriage 13
``To the pen lifting spring 18'': Su, Pe/Stock holding lever 19
The pen tip 20 receives a force in the direction of the arrow through the recording paper 2.
It is far from 1. Note that the pen holding lever 19 is attached to the support shaft 22.
It can be rotated around.

Also, a pen holding spring 23 is attached to the top of the pen 17, and when the electromagnetic plunger 24 is energized, the movable core 25 moves in the opposite direction to the arrow A direction, and the pen holding lever 19 is moved around the spindle 22 in the opposite direction to the arrow entry direction. 0 to compress the pen lifting spring 18, and the pen tip 2o is pressed against the recording paper 21 by the pen holding spring 23. The electromagnetic plunger 24 is designed so that it can rotate in the direction of arrow B using the protrusion 2Y as a fulcrum. A gap 28 is provided in the carriage 13. Note that normally the spring 2 shown in Fig. 5
9 applies a force in the direction opposite to the direction of arrow B, and the movable core 25 is applied to the radial groove 31 provided in the bearing 30 shown in FIG.
are fitted and positioned.

Further, an electromagnetic plunger 32 for a trigger is integrally mounted on the electromagnetic plunger 24. A trigger sheet metal 34 is integrally attached to the movable core 33 of the trigger electromagnetic granger 32, and is lifted up in the direction of arrow C by a coil spring 36. Furthermore, it is engaged with the belt 36 that is not fixed to the carriage 13. Gear 39. A roller 37 and a trigger electromagnetic granger 32 are integrally attached to the belt holder opposite thereto.

In the above configuration, pen color changing will be explained.

When the trigger electromagnetic plunger 32 is excited, the movable core 33
compresses the coil spring 3'5, and the trigger plate 34, which is integrally attached to the movable core 33, moves in the direction of arrow C, and as shown in FIG. 7, the gear 39 meshed with the belt 36. The teeth provided at the tip of the trigger plate 34 fit together.

When a drive signal is applied to the carriage drive pulse motor 15 in the above state to move the carriage 13 in the direction of the arrow, the belt 38 fixed to the carriage moves in the direction of the arrow, and the belt 38 not fixed to the carriage moves in the direction of the arrow. Since the belt 36 moves in the opposite direction, the gear 39 meshed with the belt 36 and the trigger metal plate 34 fitted therewith receive a force in the direction opposite to the arrow direction, and are formed so that they move together with the trigger metal plate 34. The electromagnetic plunger 24 receives a force in the direction of arrow E using the protruding portion 27 as a fulcrum as shown in FIG.

Therefore, the movable core 26, which is positioned by the spring 29 in the radial groove 31 of the bearing 30, receives a force in the direction of arrow E.
Move along the radial grooves 31.

At this time, by controlling the pulse signal applied to the carriage drive pulse motor 15, the movable core 26 can be moved to any position in the radial groove 31. In addition,
The groove 31 is formed in the same width as the pen holding lever 19 arranged corresponding to each color pen, and the movable core 2
A desired color of the pen 17 can be selected by moving the pen 17 to any radial position.

Effects of the Invention As described above, the present invention is inexpensive because there is no need to increase the number of electromagnetic plungers even when there are many 71Vr colors in the pen.
We can manufacture color changing devices in small spaces.
