Description

[Detailed Description of the Invention] The present invention relates to a Tri-Bird's Aid device, which is an exhaust gas measuring device for automobiles.

This type of device is equipped with two pens, a recording pen and a tracking pen, and the recording pen is operated according to instructions from a computer.
While the instructed driving mode is recorded on chart paper that is conveyed at a constant speed, the driver drives the automobile while following the tracking pen along the instructed driving mode.

In conventional devices of this kind, an extremely long chart paper is wound around a holding drum, one end of the chart paper pulled out from the holding drum is placed along the drum, and then wound around the take-up drum. The structure is such that the recording pen and tracking pen are placed against the chart paper that is rotated and positioned on the circumference of the recording drum, and when the chart paper is used up after several measurements, it is replaced with a new chart paper. It was like that.

However, in the conventional type described above, there is a large economic loss because the expensive chart paper is disposable, and in addition to the recording drum, it has a holding drum and a winding drum with a fairly large diameter, so the overall device size is quite large. In addition to this, the length of the welding of the chart paper to the recording drum is increased, which requires a separate guide drum with a small diameter, which complicates the structure.Furthermore, problems may occur due to poor winding of the chart paper. There were various drawbacks such as:

The present invention aims to eliminate the above-mentioned drawbacks all at once, and focuses on the fact that the indicated running mode recorded by the recording pen only needs to be displayed on the chart paper for a relatively short period of time while the tracking pen follows it. The chart paper is made endless and is passed around the recording drum, so that when the endless chart paper is positioned on the circumference of the recording drum, the instruction traveling mode can be recorded on the endless chart paper, while the recording drum The present invention is characterized in that when the endless chart paper is separated from the paper according to the above situation, the instructed running mode recorded on the paper is erased.

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

In the figure, a recording drum 2 and a guide drum 3 are rotatably arranged in a case 1.
An endless chart paper 4 was passed between them.

The endless chart paper 4 is rotated and fed at a constant speed in the direction of the arrow in the figure by rotating at least one of the drums 2 and 3 using a motor (not shown).

In addition, this endless chart paper 4 has a guide drum 3 with a much smaller diameter than the recording drum 2, and by bringing both drums 2 and 3 close together, the length of contact with the recording drum 2 is increased, and this length is indicated by l in the figure. ) has been lengthened.

The portion of the endless chart paper 4 located on the circumference of the recording drum 2 (hereinafter this portion is referred to as the recordable portion, the length of which is l) has a portion extending from the front side to the rear side in the rotational direction of the recording drum 2. A recording pen 5 and a tracking pen 6 are sequentially arranged,
A see-through window 7 is provided in a part of the case 1 so that the tracking pen 6 can be visually observed from the outside of the case 1.

The recording pen 5 is operated according to instructions from the computer (illustrated path).
The instruction running mode is recorded on the recordable portion of the endless chart paper 4, and this recorded instruction running mode is recorded on the recording drum 2 after the endless chart paper 4 has passed the tracking pen 6 as it rotates. The characters are erased when separated from the circumferential surface.

For this reason, for example, the circumferential surface of the recording drum 2 is coated with dark wax, while the endless chart paper 4 is formed of a translucent plastic film.

That is, due to the pressure-sensitive action of the recording pen 5, the indicated running mode is embossed on the surface of the endless chart paper 4, and when the endless chart paper 4 is separated from the circumferential surface of the recording drum 2, this The highlighted instruction driving mode will be erased.

Further, in order to make the characters erasable in this way, magnetism may be used. In this case, the endless chart paper 4 is coated with a color that develops due to magnetism, while the recording pen 5 is used as a magnet. Furthermore, as shown in FIG. 2, a degaussing head 8 is provided behind the tracking pen 6 (in front of the recording pen 5).

Note that, as shown in FIG. 3, if a paint that develops color due to magnetism is applied to the circumferential surface of the recording drum 2 itself, there is no need to use the endless chart paper 4 and the guide drum 3 separately.

Next, the operation of the above-mentioned constituent device will be explained.

As the endless chart paper 4 is rotated and fed, an instruction driving mode is recorded on its recordable portion by a recording pen 5, and the driver drives the automobile while aligning the tracking pen 6 along the instruction driving mode through the see-through window 7.

Once the instructed running mode has been recorded on the endless chart paper 4, when it is separated from the circumferential surface of the recording drum 2, the instructed running mode is erased, so the instructed running mode can be newly recorded in this area as many times as desired. , the measurements are repeated in this way.

As is clear from the above description, the present invention is extremely advantageous in terms of cost since the chart paper can be used repeatedly without being thrown away.

In addition, there is no need for a separate large-diameter drum such as a holding drum or a winding drum other than the recording drum, and there is no need for a special drum for increasing the contact length of the chart paper with the recording drum. The entire device can be downsized and the structure can be simplified.

Furthermore, since the chart paper is endless, there are no problems due to poor winding, and stable operation is always achieved.
