Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an x-y plotter, which is one of data output devices for plotting figures, graphs, etc. on paper, and particularly relates to its pen holder exchange mechanism.

[Conventional technology]

4 and 5 are diagrams for explaining a conventional X-Y plotter. FIG. 4 is an external perspective view, and FIG. 5 is a perspective view showing the internal mechanism. This device has an external appearance as shown in Fig. 4, and its internal mechanism is as shown in Fig. 5, with a pulley 3 attached to the shaft of a motor 2 provided on the left frame 1, and a pulley 3 attached to the right frame 4. A carriage 7 is driven left and right on a guide shaft 6 by a wire 5 stretched between a pulley and a pulley, and the carriage 7 is moved up and down to move a pen 8 gripped by the carriage toward and away from the paper. For example, 180 degrees such that the pen 8 approaches and separates the shaft 9 for
a step motor 10a that rotates reciprocatingly within a range;
A roller 1 is rotationally driven by a step motor 10b attached to the right frame 4 in the same manner as the motor 10a.
1, a pen holder 13 holding a plurality of pens 12, etc. When in use, the recording paper is sandwiched between the roller 11 and a vintillonilla (not shown), and the motor 1
Rotate 0b to move the paper in the forward direction (Y direction),
Rotate the motor 2 to move the carriage 7 in the left and right direction (X direction)
The pen 8 is moved to the carriage 7, and the pen 8 is used to record on the paper. When replacing the pen 8 stuck in the carriage 7, drive the carriage 7 out of the recording area on the left, return the pen 8 to the empty space of the pen holder 13, and replace the multiple pens held in the pen holder. The desired pen is selected from among 12 pens. The carriage 7 has a claw 14 for gripping the pen 8, and the claw 14 can be opened and closed by rotating the shaft 9 in a direction opposite to the vertical movement of the carriage. Further, the pen holder 13 has a plurality of pens 12 arranged parallel to its rotation axis 15.
is held on the circumference, and when selecting the pen, motor 1
This is done by transmitting the rotation of 0b to the pen holder 13 via the roller 11 and a bevel gear (not shown).

[Problem that the invention seeks to solve]

The problem with the above configuration is that when replacing the pens 12 held in the pen holder 13, for example, when replacing a ballpoint pen with a set of felt-tip pens, each pen must be replaced one by one, which is time-consuming. was there.

[Means for Solving the Problems] The present invention provides an X-Y plotter that solves the above-mentioned problems. An X-Y plotter that plots multi-color plots while automatically changing one of the pen holders, characterized in that the pen holder is detachably attached to a shaft that holds and rotates the pen holder. This is done by the pen holder exchange mechanism.

[For production]

The pen holder exchange mechanism of the X-Y block described above allows the pen holder holding multiple pens to be detachably attached to the rotational drive shaft of the pen holder, thereby exchanging the set of four pens held in the pen holder together with the pen holder. This makes it easier to replace the pen set.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a diagram for explaining one embodiment of the present invention,
A is a top view, and b is a cross-sectional view taken along line bb' in figure a.

This embodiment includes a pen holder holding member 25 attached to a hollow shaft 22 as shown in FIG.
6 and a knob 27, and is detachably attached to a shaft 29 biased upward by a spring 28, and is capable of detachably holding a plurality of pens 30 on the same two circumferences. The pen holder 32 has a pen holder 32. In addition, in Fig. 1, 20 is a frame;
21 is a shaft vertically fixed to the frame and rotatably supports the hollow shaft 22; 23 is a bevel gear fixed to the hollow shaft 22; and 24 is a driving bevel gear.

Further, this embodiment will be explained with reference to an exploded perspective view in Fig. 2.
I will clarify. In the same figure, a stepped hole 33 is provided in the center of the pen holder 32, a shaft 29 having a pin 26 is inserted into the liquid hole 33, and a knob 27 is screwed together with a spring 28 in between. 29 is always biased upward.

The pen holder 32 also has a positioning protrusion (not shown) formed on its lower surface. The pen holder holding member 25 attached to the hollow shaft 22 has a shaft 2 of the pen holder in the center.
9 is inserted, and a groove 35 in which the pin 26 of the shaft 29 engages is formed as shown in the developed view of the liquid hole 34 shown in FIG. An engaging recess 36 is formed.

In this embodiment configured as described above, the positioning protrusion of the pen holder 32 is engaged with the groove 36 of the pen holder holding member 25, the knob 27 is pressed against the spring 28, and the shaft 29 is pressed.
While inserting the pin 26 into the hole 34 of the pen holder holding member 25, rotate the pin 26 along the groove 35 and release the pressure on the knob 27 when the pin 26 passes the protrusion 37.
2 is positioned and attached to the pen holder holding member 25. In addition, to remove the pen holder 32 from the pen holder holding member 25, rotate the knob 27 in the opposite direction to remove the pin 2.
6 can get over the protrusion 37 of 435, so the pen holder 32 can be removed more easily than the pen holder holding member 25.

〔Effect of the invention〕

As explained above, according to the present invention, by separating the pen holder from the shaft of the pen holder and making it detachable, it becomes possible to replace the pen set housed in the pen holder with the pen holder. Pen replacement work becomes extremely easy.
