Description

[Detailed description of the invention] This invention automatically exchanges recording pens using a storage pen holder that stores and holds a plurality of recording pens and a movable pen holder provided on a carriage that freely drives on the X-Y recording surface. , relates to a multi-pen X-Y recorder that performs multi-pen recording.

In conventional multi-pen X-Y recorders of this type, the storage pen holder is fixed to the main body of the recorder.

However, fixing the storage pen holder in this manner requires extremely strict maintenance of setting accuracy, and therefore the following inconveniences often occur.

1. For some reason, if the position of the pen holding part of the storing part pen holder or moving part pen holder changes, the data after a misstep changes.

2. In the storage pen holder and the movable pen holder, a high degree of component accuracy is required in order to smoothly replace the pen, which has the disadvantage of increasing costs.

The present invention was developed to eliminate the above-mentioned drawbacks, and provides a multi-pen X-Y recorder that allows smooth pen exchange by giving the storage pen holder a degree of freedom in the vertical and front-back directions. It is something to do.

Hereinafter, the present invention will be described in detail with reference to one embodiment.

FIG. 1 is a front view showing an embodiment of the present invention. In the figure, 1 is a main body, 2 is a storage pen holder support part provided almost upright on the main body 1, 3 is a storage pen holder, 4 is a recording pen, and 5 is freely driven on the X-Y plane. 6 is a drive mechanism of the carriage 5, and 7 is a movable pen holder provided on the carriage 5. Although not shown, the recording pen 4 is partially or mostly covered with a magnetic material such as iron, and the storage pen holder 3 and the moving pen holder 7 are provided with magnets (FIG. 2, 11). It is installed. Therefore, the recording pen 4 and the storage pen holder 3 or the movable pen holder 7 form a magnetic mechanism.

Further, the positional relationship between the storage pen holder 7 and the movable pen holder 3 is adjusted so that they do not collide when the recording pen 4 is automatically replaced.

FIG. 2 shows the storage pen holder 3 shown in FIG.
In the figure, reference numeral 8 denotes a screw receiving portion for fastening the storage section penholder provided on the storage section penholder support portion 2, 9 a spring, 10 a set screw that engages with the screw receiving portion for fastening the storage section penholder 8, 11 a magnet, and 12 a spring attachment portion provided on the main body portion 1 and the storage section penholder 3 to which the spring 9 is attached. Here, a joint is formed by the storage section penholder 3, the storage section penholder support portion 2, the main body portion 1, and the spring 9. In this case, the screw receiving portion for fastening the storage section penholder 8 may be provided on the main body portion 1.
Furthermore, although not shown, the screw hole provided in the pen holder 3 for engaging with the set screw 10 is an elongated hole extending in the vertical direction. Therefore, the pen holder 3 has a certain degree of freedom in the vertical direction, i.e., in the direction of the arrow A.

In addition, since the tip of the screw receiving part 8 for fixing the storage pen holder is tapered and smoothly rounded, the storage pen holder 3 has a structure that has a slight degree of freedom in the direction of arrow B.

Next, the operation of the apparatus shown in FIGS. 1 and 2 will be explained.

Upon receiving a pen exchange command from an internal control circuit (not shown), the mobile pen holder 7 first attaches the recording pen 4 it owns to the open pen holder 31 of the storage pen holder 3. At this time, the pen holding portion 71 of the movable pen holder 7 becomes empty. In this state, the movable pen holder 7 takes out the desired recording pen 4 from the storage pen holder 3. The pen exchange operation of the recording pen 4 is performed as described above.

The effects of this invention are described below.

1. Since the storage pen holder 3 is configured to have a slight degree of freedom in the vertical and front-back directions, there is no need for a high degree of precision in parts and precision in the operation of equipment, which has the advantage of being inexpensive.

2. Even if the pen holding portion of the storage pen holder 3 or the movable pen holder 7 is damaged for some reason, there is an advantage that the pen replacement operation can be performed without interruption for the same reason as 1.
