Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pen holding mechanism for the XY70.The purpose of this invention is to securely hold a pen with a simple structure formed by bending a single thin metal plate. The purpose is to provide a holding mechanism.

The first I21 is a simplified mW of a known XY plotter.
It shows. In the figure, (1) is the main body of the XY10 tube, (2) is a slider frame, which is transferred in the X direction in the figure within the main body (11), and (3) is a pen carriage, which is attached to the slider frame (2). (4) is an arm held rotatably by a predetermined amount on the Benn carriage (3); The pen holder (5) is fixed to the arm (4), and a pen (6) is detachably attached to the pen holder (5). ), the pen (6) comes into contact with and separates from the recording paper.

By the way, the conventional pen holding mechanism of the XY70 is as shown in FIGS. 2 and 3.

Fig. 2 is a plan view of the main part, and Fig. 3 is a sectional view of the main part. In the figure, (5) is a pen holder made of a thin metal plate bent into a substantially cow shape, and its base end (5a) is fixed to the arm (4) with a screw (7).
a pair of elastic curved arms (5b) from the base end (5a);
(5b) is prominent. (6) is a pen held between the curved arms (5b), (5b), which can be easily attached and detached by moving it with your fingers or the like in the direction of the arrow in FIG. (6a) is the brim part provided on the pen (6), and the grooves (5C), (5C) of the curved arm part (5b), (5b).
) (see Figure 83) to position the pen (6) in the vertical direction. In addition, in FIG. 3, (8j is the pivot shaft of the arm (4).

However, in the above conventional configuration, since the pen (6) is simply held between the curved arms (5b) by elastic force, variations in the dimensional accuracy of the arc portion of the curved arms (5b), etc. The pen tip (6b) tends to move in the direction of the arrow in FIG. 3 due to fluctuations in elastic force, etc., which adversely affects drawing quality.

The present invention has been made in view of the above-mentioned points, and provides a pen holding mechanism that is simple and secure in pen holding.The details of the present invention will be explained below with reference to an embodiment shown in FIGS. 4 to 6. . Note that components that are the same as those of the prior art are given the same numbers, and their explanations will be omitted.

In the figure, (9) is a pen holder formed by pressing a thin metal plate, and has a proximal end (9a) and a pair of elastic pairs protruding from the left and right sides of the proximal end (9a) in Fig. 6. The curved arm portions (9b), (9b) of the proximal end portion (9a) are integrally formed with a pair of protrusions (9d), (9d) protruding from the upper and lower sides in FIG. 6. .

This pen holder (9) is positioned and fixed to the arm (4) by screws (7) within the concave portion of the arm (4) at its base end (9a), as in the conventional example.

Then, move the pen (6) from the direction of the arrow in Figure 3 to the curved arm (9).
b) and (9b), and press the brim part (
6a), curved arm part (9b), groove (9C) of (9b), (
9C) and push the pen (6) all the way,
The pen (6) is held and positioned between the curved arms (9b), (9b). In the installation state of this pen (6), the pen (6) has a curved arm (9b), (9b)
-6) $4 It is urged inward by the elastic force acting in the direction of arrow 8 in Figure 4, and the cylindrical outer periphery is
d) and (9d), and the structure is such that the pen (6) cannot be moved in the direction of the arrow in Figure 5 with respect to the pen holder (9) due to slight vibrations, shocks, etc. .

As described above, in the present invention, a pen holder is formed by bending a single sheet of metal, and a pair of elastic curved arms are formed, and a pair of upper and lower protrusions are formed, and the pen holder is held by the pair of curved arms. Since the pen is pressed against the pair of upper and lower protrusions by the elasticity of the curved part, the present invention provides a simple pen holding mechanism that does not require any other special parts for fixing the position, and that can hold the pen reliably. This is what we provide.
