Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pen holder used in a printer that performs printing using a pen.

[Conventional technology]

2. Description of the Related Art In general, some printers, which are a type of output device for various types of information, are configured to perform printing using a pen.

A printer using this pen attaches a pen holder directly to a carriage that moves relative to the printing surface, attaches multiple pens of different colors to this pen holder, selects the pen of the color to print, and prints. It is designed so that it can be easily printed in color.

[Problem that the invention attempts to solve]

However, conventional pen-based printers print using a special pen that is uniquely prepared for each printer model, and it is not possible to print using commercially available pens. .
Of course, it was not possible to freely select the properties of the ink and the thickness of the printed characters. In addition, conventional printers
It is only possible to print in a pre-prepared color, and it is not possible to print in a color freely selected from commercially available color pens. Furthermore, in the past, multiple pens were attached to a pen holder, so each pen was made small, so the ink capacity was small, and the ink ran out during printing, making it difficult to replace the pen. In addition, there was a risk of discontinuous printing due to pen replacement.

In view of these points, it is possible to hold various pens with different thicknesses, lengths, shapes, etc. while accurately centering the pen tip, and it is possible to hold various pens with different thicknesses, lengths, shapes, etc., while accurately centering the pen tip.
The present applicant has already filed an application for a pencil mechanism that allows printing by freely selecting the thickness of the print.

The object of the present invention is to provide a pen holder that can hold a pen with a very large diameter that cannot be held by the pen chuck mechanism of the previous application, and can print even thicker characters.

[Means for solving problems]

The pen holder of the present invention includes a pen-shaped support mounted in a pen-chuck mechanism formed in a carriage that moves relatively parallel to a printing surface, and a pen-shaped support that protrudes from the pen-shaped support and holds a pen on the outside of the carriage. and a clip member that can hold the clip.

[Effect]

According to the pen holder of the present invention, the pen-shaped support is mounted inside the pen-chuck mechanism so that the clip member faces outside the pen-chuck mechanism, and the pen is held by this clip member, so that it is possible to hold an extremely thick pen that cannot be inserted into the pen-chuck mechanism. It can be held outside the carriage.

〔Example〕

The present invention will be explained below with reference to embodiments shown in the drawings.

First, a schematic configuration of a printer using a pen chuck mechanism for attaching a pen holder according to the present invention will be explained. In this printer, as shown in FIGS. 2 and 4, a substrate 4, onto which paper 3 is fed, is placed between frames 2, 2, which are fixedly erected at both ends in the width direction. It is set horizontally. Hereinafter, the upper surface of the substrate 4 will be referred to as a printing surface P. Above this substrate 4, an upper fixed shaft 5 and a lower rotating shaft 6 are horizontally suspended in parallel between both frames 2, 2. A carriage 7, which is provided with four plier mechanisms 1, is mounted on the fixed shaft 5 and the rotating shaft 6 so as to be slidable in the axial direction by bearings (not shown). Further, both ends of a carriage drive cable 10 such as a belt wound around a drive wheel 8 and a driven wheel 9 provided on the outside of each frame 2 are fixed to both widthwise ends of the carriage 7, respectively. The carriage 7 is reciprocated parallel to the printing surface P in the X direction, which is the axial direction of each shaft 5, 6, by moving a carriage drive cable 10 via a drive wheel 8. The paper 3 is driven in the Y direction perpendicular to the X direction by a paper drive mechanism (not shown). Therefore, by combining the movements in the X direction and the Y direction, desired printing, etc. can be performed.

Next, the pencil chuck mechanism 1 will be explained with reference to FIGS. 2 and 3. FIG. 2 shows one pencil mechanism 1 in detail. This pliers mechanism 1 consists of a cylindrical sleeve 12 mounted in a sleeve guide 11 of a carriage 7 so as to be able to reciprocate in the vertical direction perpendicular to the printing surface P, and a cylindrical sleeve 12 mounted on the inner surface of the sleeve 12 at equal intervals in the circumferential direction. A plurality of (three in this embodiment) provided holding claws 13, 13
It is formed by... The sleeve 12 and the holding claw 13 are integrally molded from a synthetic resin material, etc., and the sleeve 12 is always kept in contact with the printing surface P by a compression spring 14 interposed between its lower end and the bottom plate 7a of the carriage 7. The upper end of the sleeve guide 11 is stopped by contacting the upper stopper 11a of the sleeve guide 11. Each holding claw 13 elastically clamps and holds a pen 15, and in this embodiment, the pen 15 is formed to hold a commercially available pen. Since many commercially available pens have a hexagonal or circular cross-sectional shape, in order to properly hold both, it is preferable to provide three holding claws 13 as in this embodiment, or six holding claws 13. Each holding claw 13 is long in the vertical direction and curved to be convex toward the outside, and in order to elastically hold the pen 15, in a free state where the pen 15 is not held, As shown by chain lines in FIG. 2, the inner diameter of each holding claw 13 is smaller than the outer diameter of the pen 15. Further, in order to easily and reliably center the nib 15a of the pen 15, and to securely hold and hold the pen 15, which is a commercially available pen, which is often tapered in the direction of the nib 15a, with sufficient strength. The elasticity of each holding claw 13 is equal to the pen tip 15.
The lower end in the direction a is larger than the upper end. In order to reinforce the elasticity with which the holding claw 13 holds the pen 15, as shown in FIG. It is best to wrap it around the outer periphery.

In this embodiment, when the holding claw 13 is stopped at the raised position, the pen tip 15a of the pen 15 is positioned at a mounting reference position protruding from the sleeve 12 by a certain length, that is, at a certain height H from the printing surface P. A pen position adjustment mechanism 17 is provided which allows the pen to be held by the holding claw 13. This pen position adjustment mechanism 17 has a positioning protrusion 18 protruding from the outside of the sleeve 12, and a positioning stopper 19 that stops the descent of the sleeve 12 when the lowering positioning protrusion 18 comes into contact with the pen tip 15a. It is formed by a printing surface P that stops the pen 15 from descending. As shown in FIG. 2, the distance H between the lower surface of the positioning protrusion 18 and the upper surface of the positioning stopper 19 when the sleeve 12 is stopped at the highest position is such that the nib 15a of the pen 15 at that time is It is formed to be equal to the height H rising from the printing surface P.

The pen holder 20 of the present invention, which is attached to the pencil chuck mechanism 1, has a pen-shaped support 21 having an outer diameter that can be inserted into the pen chuck mechanism 1, as shown in FIG. Like the pen 15, this pen-shaped support 21 has a tapered tip 21a at the lower end, and the pen-shaped support 21
A connecting bar 22 that extends laterally is integrally provided at the upper end of the housing. One clamping arm 2 of the clip member 23 is attached to the tip of the connecting bar 22.
The base end of 4A is integrally provided in a protruding manner. This clip member 23 has clamping arms 24A and 24B which are pivotally connected to each other at their middle parts, and each clamping arm 24A, 24B has an arcuate holding part 25A for holding the pen 15 therebetween. , 25B are formed such that they are connected to each other and the end of the holding portion 25A is connected to the connecting bar 22.

In addition, the pivot portion 2 of each clamping arm 24A, 24B
There are flat tabs 27A and 27B on the tip side from 6.
are formed, and the knobs 27A, 27B are always
A spring member 28 for expanding the holding parts 25A and 25B to close the space between the holding parts 25A and 25B is attached to both the holding arms 24A and 2.
It is interposed between 4B.

Next, the operation of the embodiment described above will be explained.

First, in order to install the pen 15 into the pencil mechanism 1, the pen tip 15a is directed toward the printing surface P through the opening of the upper stopper 11a of the sleeve guide 11 provided in the carriage 7. Push it in between the holding claws 13 from above. This pen 15 has each holding claw 13
The pen 15 is inserted downward while expanding against its elasticity, and when the pen 15 is inserted to a certain extent, the frictional force between the pen 15 and each holding claw 13 becomes
The elasticity becomes larger than that of the compression spring 14, and the elasticity of the compression spring 1
The sleeve 12 starts to descend against the elastic force of the sleeve 4. Thereafter, the positioning protrusion 18 protruding from the sleeve 12 comes into contact with the positioning stopper 19, thereby physically preventing the sleeve 12 and the holding claw 13 from descending. Then, when the pen 15 is pushed further, the pen 15 is inserted while further pushing each holding claw 13 apart, and the pen tip 1 of the pen 15 is inserted.
When 5a comes into contact with the printing surface P, its descent is physically prevented. When the pushing force of the pen 15 is released in this state, the sleeve 12, the holding claw 13, and the pen 15 are raised together by the return elasticity of the compression spring 14, and the upper end surface of the sleeve 12 is pushed up against the upper stopper 11a of the sleeve guide 11. It is stopped at the highest position by contacting with.

In this state, the pen 15 is held elastically by each holding claw 13, and the elasticity of the lower end of the holding claw 13 is greater than that of the upper end, so that the centering of the pen tip 15a is accurate, and Even if the pen 15 is tapered, it can be held with sufficient holding force.

Therefore, if you want to use a pen 15 with a thick outer diameter that cannot be inserted into the pen holder mechanism 1, pinch both the grips 27A and 27B of the pen holder 20 with your fingers to widen the space between the gripping arms 24A and 24B. The pen 15 with a thick outer diameter is positioned inside the arms 24A, 24B, and both the knobs 27A, 2
7B, the gripping arms 24A and 24B are closed by the elasticity of the spring member 28, and the pen 15 is gripped by the clip member 23. At this time, pen 1
The gripping position of the pen 15 by the clip member 23 is adjusted so that the lower end of the pen 15a of No. 5 is located on the same plane as the lower end of the tip 21a of the pen-shaped support 21. Then, the aforementioned pencil mechanism 1
In the same manner as the operation of attaching each pen 15 inside the sleeve guide 11, the tip 21a of the pen-shaped support 21 is directed from the opening of the upper stopper 11a of the sleeve guide 11 toward the printing surface P direction, and each holding claw 13 inside the sleeve guide 11 is moved. Insert it into the space from above. When the pen-shaped support 21 continues to be inserted for a certain period of time, the frictional force between the pen-shaped support 21 and each holding claw 13 becomes larger than the elasticity of the compression spring 14, and the sleeve 12 resists the elasticity of the compression spring 14. begins to descend. This lowering of the sleeve 12 continues until the positioning protrusion 18 contacts the positioning stopper 19. When the positioning protrusion 18 contacts the positioning stopper 19, the sleeve 12 is inserted while pushing the pen-shaped support 21 and each holding claw 13 apart. Then, move the pen-shaped support 2
When the pointed end 21a of 1 comes into contact with the printing surface P, its descent is physically prevented. Then, when the pushing force of the pen-shaped support 21 is released, the sleeve 1
2. The holding claw 13 and the pen-shaped support 21 are raised together by the return elasticity of the compression spring 14;
When the upper end surface of the sleeve 12 comes into contact with the upper stopper 11a of the sleeve guide 11, it is stopped at the uppermost position. As a result, the axis of the pen 15 held by the clip member 23 of the pen holder 20 is aligned with the axis of the pen-shaped support 21 at
It will take a position shifted in the direction. In this way, by mounting the pen-shaped support 21 of the pen holder 20 at a predetermined height within the pencil mechanism 1, the clip member 23 holds the pen 15 with a thick outer diameter at a predetermined height outside the cartridge 7. can do.

The clip member 2 of this pen holder 20
In order to perform printing etc. with the thick outer diameter pen 15 held by the pen holder 20, the axis of the pen-shaped support 21 of the pen holder 20 and the axis of the pen 15 held by the clip member 23 should be aligned in the X direction. Since the deviation is solved in advance and this data is stored in the printer's memory, by operating the button for printing with the pen 15 held by the pen holder 20, the carriage 7 moves a predetermined distance in the X direction. Then, the pen 15 is moved to a predetermined position on the paper 3. Thereafter, the pen lowering mechanism provided in the carriage 7 moves the pen holder 2 together with the sleeve 12 and holding claw 13.
0 is lowered, and a predetermined print, etc. is performed on the paper 3 while moving the paper 3 and the carriage 7 relative to each other using the thick outer diameter pen 15 held by the clip member 23 of the pen holder 20. can be carried out.

As described above, according to this embodiment, by attaching the pen 15 to the pen chuck mechanism 1, it is possible to center the pen tip 15a of various pens 15 having arbitrary thicknesses, lengths, shapes, etc. by extremely simple operations. It is possible to accurately perform and hold the ink, to print using any commercially available pen, and to select the color and properties of the ink, the thickness of the print, etc. Furthermore, even a very thick pen 15 that cannot be attached to the pencil chuck mechanism 1 can be held in the clip member 23 of the pen holder 20. Predetermined printing, etc. can also be performed using the .

Note that the present invention is not limited to the above-mentioned embodiments, and can be modified in various ways as necessary.

[Effect of idea]

As explained above, according to the present invention, even extremely thick pens that cannot be attached to the pen chuck mechanism can be held at a predetermined height. Can be expanded.
