JPS5935770Y2 - Vertical multi-pen recording instrument recording stand - Google Patents

Description

[Detailed Description of the Invention] Recording instruments that use strip charts are generally divided into two types: flatbed type and vertical type.

Since the recording paper of the flatbed type is arranged horizontally, it is easy to manually write necessary data and items on the surface of the recording paper during recording operation.

The disadvantage is that it requires a large installation space.

Since the vertical recorder is installed so that the recording paper advances along the vertical direction, it requires a small installation space, but it has the disadvantage that it is difficult to write on the recording paper surface by hand.

Figure 1A shows part of a vertical recorder.

The recording paper table 2 is supported at its upper end by a shaft 1, and is provided so as to be able to rotate downwardly and forwardly about the shaft 1 as a fulcrum.

A portion of the recording paper base 2 extending approximately 200° around the axis 1 is cylindrical, and the recording paper on top of this cylindrical portion is placed in contact with the recording paper at equal intervals in the traveling direction of the recording paper. Several pen nibs 5 are arranged.

There is also a vertical recorder in which the lower end of the recording paper base 2 is pulled forward to make writing easier.

In the case of such a vertical multi-pen recorder, when the lower part of the recording paper base 2 is pulled out as shown in FIG. The pen holder 4 comes into pressure contact and lifts up around the pen shaft 3 of the pen holder 4, resulting in a change in the interval between the pen shafts, which causes an error due to a shift in the time axis and affects measurement accuracy.

The present invention provides a recording stand for a vertical multi-pen recorder that solves these problems.

FIGS. 2 and 3 show a recording stand according to the present invention.

5 is a recording stand 7 with several pen tips provided in the same way as in Fig. 1.
It is fixed and provided relatively.

The recording table 7 is provided with a cylindrical sprocket wheel 8 for feeding the recording paper, with about half its circumference exposed to the outside.

A plate-shaped recording paper base 6 is fixed to the recording base 1 so that one edge approaches the outer peripheral surface of the sprocket wheel 8 in a tangential manner and is tilted downward at approximately 3 Cf from the horizontal on one side of the sprocket wheel 80. .

One of the several pen nibs 5 is in contact with the recording paper on the surface of the sprocket wheel 8, and the other pen nibs 5 are provided so as to be in contact with the recording paper on the recording paper base 6.

The recording paper 11 is pulled out from a recording paper holder 12 provided on the recording table 7 by hanging it on the surface of the sprocket wheel 8, passes over the recording paper table 6, and is sent vertically downward from the side opposite to the sprocket wheel 8. Ru.

A shaft 9 is provided at the opposite end of the recording paper base 6 from the sprocket wheel 8, and a shaft 9 is provided vertically along the back side of the recording paper 11 so that the lower end side can rotate toward the front side of the recording paper 11 using the shaft 9 as a fulcrum. A writing table 10 is provided extending in the direction.

This writing stand 10 is fixed with a drawer 1 by an appropriate support arm (not shown) together with the recording paper 11 so as to be in line with the recording paper base 6 as shown by the chain line in FIG. It has become.

According to the recording stand of the present invention, the recording paper stand where the recording paper is written with the recording pen is fixed relative to the pen, so the interval between the pens does not change, and the writing for writing can be done without changing the distance between the pens. The stand is provided so that it can be tilted to make it easier to write on it.1 Normally, it is hung vertically on the back side of the recording paper to save space, and the writing stand can be pulled out and used only when writing. Therefore, it is possible to construct a vertical multi-pen recording instrument that is easy to use, does not take up much space, and does not cause a time axis error.
