Abstract

PURPOSE:To ensure that a recording pen is stable without moving out of place by matching the center of a magazine for storing recording pens with an axis on which the recording pen moves, and maintaining one rotor retaining side of the magazine in a linear state while causing a pen holder on the other side to shift its position in freely operating manner during the replacement of the recording pen. CONSTITUTION:A carriage on which a recording pen 2 is mounted moves on a guide 6. The carriage 4 stops at an arrow (a) position during the replacement of the recording pen 2 and replaces the existing pen with another recording pen 2 retained in the magazine 1. The center 5 of the magazine 1 coincides with an axis on which the recording pen 2 is allowed to move in parallel with a guide 6. Therefore, the shape of a rotor 3 for the magazine 1 can be reduced to a maximum allowable short size. In addition, when the recording pen 2 is moved for replacement, one recording pen-holding side of the rotor 3 on the magazine 1 is maintained in a linear state and stops in a half- fixed condition after rotation in parallel with a direction in which the carriage 4 moves, to act as a guide. On the other hand, the other pen holder side is moved out of place in a freely operating manner during the replacement of the recording pen 2.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pen exchanging section in an XY plotter used for recording and making figures.

[0002]

2. Description of the Related Art As a conventional device of this type for an XY plotter used for automatically recording and creating a figure, an X of a carriage for freely moving a recording pen in the left and right directions of the X axis. Since the axial position to move in the axial direction does not match the central axis position of the magazine that houses the recording pen,
There is a drawback that the magazine that accommodates the recording pens becomes large and the entire apparatus also becomes large, and when the recording pens are moved and replaced, the center of the magazine and the recording pens are moved in the X-axis direction. When the axes do not coincide with each other, when the recording pen is moved in the X-axis direction, rotational torque is applied to the rotary blades of the magazine, and the magazine is unstable. Also, even if they match, both the rotary blade of the magazine and the pen holder are movably displaced so that they can be opened and closed freely when the recording pen is replaced.
Since there is no guide for the recording pen, it becomes unstable when the recording pen is replaced, and even when the rotary blade of the magazine is semi-fixed, the rotary blade is not straight and parallel to the X-axis direction,
Since the recording pen becomes unstable due to sideways movement, there is a drawback that the recording pen is easily displaced.

[0003]

SUMMARY OF THE INVENTION The above-mentioned prior art is
It was unsuitable for downsizing the XY plotter, and was insufficient for stable operation when the recording pen was replaced. Therefore, the present invention has been made in view of the above circumstances, and an object of the present invention is to reduce the size of the magazine and the size of the XY plotter, and to improve the accuracy when exchanging the recording pen. The purpose is to provide an XY plotter that maintains stable operation and operates stably.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a recording pen exchange section in which a magazine for accommodating N recording pens and a recording pen in use are set at X. In a device having a carriage that moves freely in the left and right directions of the axis, the rotary blade of the magazine forms N blades for holding a recording pen, and the recording pen is connected to the rotary blade of the magazine. In the configuration of nipping with the pen holder, when the center of the magazine is aligned with the axis for moving the recording pen in the X-axis direction and the recording pen is moved and replaced, the rotary blade of the magazine has at least N. While rotating at an equal angle, the recording pen holding side of the rotary wing of one magazine is straight, and stops semi-fixed in parallel to the X-axis direction, while the other pen holder stops when the recording pen is replaced. Displaceable to open and close freely Is obtained characterized by comprising X-Y plotter with a recording pen replacement part characterized in that to.

[0005]

With this structure, the center of the magazine and the axis for moving the recording pen in the X-axis direction are aligned with each other, so that the shape of the rotary wing of the magazine is formed to have the shortest length. . Further, when the recording pen is moved and replaced, the center of the magazine is aligned with the axis for moving the recording pen in the X-axis direction. Therefore, even if the recording pen is moved in the X-axis direction, It is stable because it is difficult to apply rotational torque to the rotary wing, and the recording pen holding side of the rotary wing of one magazine is a straight line and semi-fixed rotation stops parallel to the X-axis direction, while the other pen holder records. Since the recording pen is movably displaced so that it can be opened and closed when it is replaced, the guide of the recording pen has a straight portion on the recording pen holding side of the rotary blade of the magazine and the rotary blade is linear and parallel to the X-axis direction. As a result, when the recording pen is replaced, it serves as a guide, does not laterally move, does not retract, etc., and does not cause displacement of the recording pen and is stable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a recording pen exchange unit according to the present invention will be described below with reference to the drawings. FIG. 1 is a partial plan view of a plotter showing an embodiment of the present invention. In the recording pen exchanging portion, 1 is a rotary magazine for accommodating eight recording pens. 2 is a recording pen, 3 is a rotary blade of the magazine 1, and 8 sets of wings for holding the recording pen 2 are formed, and
The recording pen is sandwiched between the rotary blade of the magazine and the pen holder. Reference numeral 4 denotes a carriage for freely moving the recording pen 2 in use in the left and right directions of the X axis. 2 is a plan view of the magazine portion, and FIG. 3 is a sectional view of the magazine portion. Next, this operation will be described. The carriage 4 carrying the pen 2 moves on the guide 6 (moves in parallel with the broken line 8 in FIG. 1). The carriage 4 stops at the position of the arrow a when the pen 2 is replaced, and the other pen 2 held in the magazine 1 is stopped.
To replace. In the present invention, at this time, these are arranged so that the center axis 5 of the magazine 1 and the center of the pen 2 mounted on the carriage 4 move coaxially. With this configuration, the center 5 of the magazine 1 and the recording pen 2
Since the axes for moving the guides in parallel with the guides 6 are aligned, the shape of the rotary vanes 3 of the magazine 1 is configured to have the shortest length. If the center of the magazine and the movement axis of the recording pen do not match, the shape of the rotary vanes of the magazine increases in accordance with the amount of deviation. In addition, when the recording pen 2 is moved and replaced, the center of the magazine 1 and the axis for moving the recording pen in the X-axis direction are aligned with each other. Is stable because rotational torque is less likely to be applied to the rotary blades 3 of the magazine 1, and the recording pen holding side of the rotary blades 3 of one magazine is a straight line, and semi-fixed rotation stop parallel to the moving direction of the carriage 4. However, since the other pen holder displaces the recording pen so that it can be opened and closed freely when the recording pen is replaced, the recording pen is guided by the magazine 1.
Since the rotary wing has a straight portion on the side where the recording pen is held and the rotary wing is linear and parallel to the moving axis of the carriage 4, it serves as a guide when the recording pen is replaced, and does not cause sideways retraction. In addition, the recording pen is stable without being displaced.

[0007]

As described above, according to the present invention, the shape of the rotary vanes of the magazine is constituted by the shortest length. Also,
When the recording pen is moved and replaced, it is stable even if the recording pen is moved in the X-axis direction because the rotary torque of the magazine is less likely to be applied to the rotating blades of the magazine. Without causing any withdrawal,
The recording pen is stable without displacement and the like.
