Description

[Detailed Description of the Invention] The present invention relates to an improvement of a pen recording pen mechanism used in multicolor XY plotters and the like.

Generally, in this type of recording pen mechanism, a means is often used in which a plurality of pen cartridges corresponding to recording colors are stored together in a pen holder, and the pen holder is attached to the pen cartridge. Furthermore, in such devices, protrusions are provided on the pen cartridge and the pen holder, respectively, so that the pen cartridge and the pen holder can be easily attached and detached when replacing the pen cartridge. However, the protrusions provided on pen cartridge cartridges and pen holders are extremely small due to their structure, and if you try to attach or remove the pen cartridge or pen holder by grasping the protrusions, the protrusions may be removed. You may not be able to grasp the pen properly and may drop the pen cartridge or pen holder, or touch the tip of the pen and get your hands dirty.

The object of the present invention is to eliminate the above-mentioned drawbacks of the conventional device and to realize a recording pen mechanism with a simple structure that allows the pen cartridge and pen holder to be easily attached and detached.

In the recording pen mechanism of the present invention, a pen holder that holds a plurality of pen cartridges with their pen tips positioned radially is provided with an opening from which a part of the pen cartridges protrudes, and the pen cartridge is A protrusion protrudes from this opening and serves as a grip when attaching or removing the pen holder, and the pen holder is grasped using the protrusions lined up on the circumference, and by pushing the protrusion. The pen cartridge is configured to be removed from the pen holder.

The recording pen mechanism of the present invention will be explained below with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the recording pen mechanism of the present invention. In the figure, 1 is a pen holder;
21 to 24 are pen cartridges, and 3 is a paint cartridge. The figure illustrates the case where four pen cartridge cartridges 21 to 24 are stored in the pen holder 1. The pen holder 1 is divided into four storage chambers 11 to 14 by a partition wall 10, and these storage chambers 11 to 14 are divided into four storage chambers 11 to 14. have openings 15 to 18, respectively.
is provided. Also, pen cartridge 21
- 24 have the same shape, and the pen nibs 211,
221, 231, 241 are provided, and
Projections 212, 222, 232, and 242 are provided to project from the openings 15 to 18 of the pen holder 1. Furthermore, in the paint cartridge 3,
A locking shaft 30 for locking the pen holder 1, a slit 3 for positioning the pen tip 211...

14 and attached to the pen cartridge 3 together with the pen holder 1.

FIG. 2 is a partial sectional view showing the assembled state of the recording pen mechanism configured as described above. Now, to explain using the pen cartridge 21 as an example, when the pen cartridge 21 is stored in the storage chamber 11 of the pen holder 1 as shown in the figure, the protrusion 212 will come out from the opening 15 of the pen holder 1. stand out. Furthermore, when the pen holder 1 is locked to the locking shaft 30 of the pen cartridge 3, the pen tip 211 is held in the slit 31 of the pen cartridge 3 and positioned. In addition, pen holder 1
The fixation between the pen holder 1 and the pen cartridge 21 and the locking shaft 30 of the pen holder 1 and the pen cartridge 3 are performed using a click mechanism, a friction mechanism, or the like.

Now, as above, remove the pen cartridge 21.
24 are stored in the storage chambers 11 to 14 of the pen holder 1, each protrusion 212, 222, 232, 2
42 are openings 15 to 18 of the pen holder 1, respectively.
They protrude from the center and line up on the circumference. Therefore, using the entire protrusion, the pen holder 1
When you grab it, the four protrusions 212, 22
2, 232, and 242 constitute a portion corresponding to the conventional protrusion, and the equivalent diameter of this portion is increased, so the pen holder 1 can be gripped securely, and the pen holder 1 can be easily attached and detached. be able to. In addition, the protrusions 212, 222, 23
2, 242 inside the openings 15-18, the pen cartridge cartridges 21-24 can be easily removed from the pen holder 1.

In addition, in the above description, the pen holder is shaped like a trapezoidal cylinder and has an opening provided on its outer circumferential surface. However, the shape of the pen holder and the pen cartridge stored therein are limited to those shown in the drawings. For example, it may be a cylindrical pen holder with an opening provided at its bottom.

As explained above, in the recording pen mechanism of the present invention, a pen holder that holds a plurality of pen cartridges with their pen tips positioned radially has an opening from which a part of the pen cartridges protrudes. At the same time, the pen cartridge is provided with a protrusion that protrudes from this opening and serves as a grip when attaching or removing the pen holder, and the protrusion arranged on the circumference is used to grasp the pen holder. Since the pen cartridge is removed from the pen holder by pushing the protrusion, a recording pen mechanism that can easily attach and detach the pen cartridge and pen holder can be realized with a simple configuration.
