2. Description of the Related Art FIG. 3 is a perspective view showing a support structure of an ink container in a conventional ink writing recorder. A galvanometer 1 converts a change in electric current into a rotational movement or the like and outputs it visually so that it is used, for example, in a seismograph or the like. Reference numeral 2 denotes a pen attached to the output shaft of the galvanometer 1, 2a denotes a pen tip of the pen 2 in contact with the recording paper 3, and the recording paper 3 travels in the arrow direction to draw a trace 4.

Reference numeral 5 denotes an ink container for accommodating the ink to be supplied to the pen tip 2a, which is made of a transparent or translucent transparent plastic material or the like. Reference numeral 6 denotes a cap that is fitted in the mouth of the ink container 5 while maintaining airtightness, and 6a is a ventilation hole that is provided so as to pass through the cap 6 in the vertical direction. A discharge pipe 7 is provided so as to penetrate the cap 6 so as to maintain airtightness, and a tip located inside the ink container 5 is immersed in ink. Reference numeral 8 is an ink tube, and the tip of the discharge pipe 7 located outside the ink container 5 and the pen tip
It is connected to an ink passage 2b that guides the ink to a and to a suction pipe 9 provided in the pen 2 connected to the ink passage 2b.

Reference numeral 10 denotes a holder which covers the lower surface side and the entire side surface of the ink container 5 and is accommodated therein. The holder 10 is made of a non-permeable material having a spring property, and is formed so that the accommodation capacity for the ink container 5 is slightly smaller. When the ink container 5 is housed, the side surface of the holder 10 that is in contact with the side surface of the ink container 5 elastically deforms and acts on the side surface of the ink container 5.
A frictional force is generated between the side surface of 0 and the side surface of the ink container 5,
The ink container 5 can be held at any desired position in the holder 10.

Reference numeral 11 denotes a stand to which the holder 10 is fixed, and a screw 11a is cut at the lower portion.
A base 12 supports the stand 11 and the like, and a screw 11a of the stand 11 is screwed into the base. Reference numeral 13 denotes a nut to be screwed into the screw 11a of the stand 11, and by rotating the stand 11 with the nut 13 in a loosened state in which the nut 13 is not in contact with the base 12, the holder 10 located above the stand 11 is rotated. You can change the height,
When the nut 13 is tightened to a position where it comes into contact with the base 12, the stand 11 cannot be rotated, and the holder 10 is held at an arbitrary height.

The method of using the ink recording device having the above structure will be described. First, the cap 6 is fitted into the ink container 5 containing the ink, the ventilation hole 6a of the cap 6 is covered with a finger, and the side surface of the ink container 5 is covered with a finger. When pressure is applied, the volume of the ink container 5 decreases, the internal pressure rises, and the ink rises inside the ejection pipe 7. At this time, by setting the ink container 5 to a position higher than the suction pipe 9 of the pen 2, the ink is guided to the suction pipe 9 of the pen 2 via the ink tube 8 and passes through the ink passage 2b in the pen 2. Then, it reaches the pen tip 2a, and the recording trace 4 can be drawn on the recording paper 3.

In this way, when the ink reaches the pen tip 2a, the ink container 5 is stored in the holder 10. Here, from the ink container 5 housed in the holder 10 to the pen tip 2
In order to stably supply ink to a, first, stand 1
The nut 13 screwed into the threaded portion 11a of the base 1
Then, the stand 11 is rotated and the screw portion 11a is moved up and down around the base 12 to adjust the height of the holder 10. This height is determined so that the liquid surface of the ink in the ink container 5 is always higher than the suction pipe 9, and after the height of the holder 10 is adjusted, the nut portion 13 is brought into contact with the base 12 and the screw portion 11a. Tighten against
After suppressing the movement of the stand 11 to determine the height of the holder 10, the ink container 5 is housed in the holder 10. Further, since the holder 10 is made of a material having a spring property as described above and the ink container 5 can be held at a desired position inside the holder 10, it is possible to slightly move the ink container 5 up and down in the holder 10. Fine adjustment of ink supply is possible.

As a result, since the liquid level of the ink in the ink container 5 is higher than the suction pipe 9 of the pen 2, the ink passes from the ink container 5 to the discharge pipe 7 and from the ink tube 8 to the suction pipe 9. Then, the trace 4 can be drawn on the recording paper 3 by being guided to the pen tip 2a through the ink passage 2b of the pen 2. In the case of ink replenishment, the ink refilling operation is completed by pulling out the ink container 5 from the holder 10, pulling out the cap 6 from the ink container 5, and inserting the cap 6 into the new ink container 5.

[0009]

However, when the conventional ink container support structure described above is used, the ink container 5
Since it is made of a transparent or semi-transparent transparent plastic material, the remaining amount of ink can be easily checked. However, the holder 10 is made of a non-transparent material, and when the ink container 5 is housed in the holder 10, the ink is stored. Is consumed and the liquid level of the ink drops below the upper end of the holder 10, the liquid level of the ink is hidden by the holder 10, and the remaining ink amount cannot be confirmed unless the ink container 5 is pulled out from the holder 10. There is. If it is not possible to easily check the remaining ink level in this way, neglecting to check the remaining ink level will cause ink shortages when an unexpected phenomenon such as earthquake observation recording is being recorded, and the earthquake record will not be recorded. There is a problem that you cannot get it.

According to the present invention, since the remaining amount of ink, which is the above-mentioned problem, cannot be confirmed, and the recording failure due to ink shortage is eliminated, the remaining amount of ink can be easily confirmed. An object of the present invention is to provide an excellent support structure for an ink container that can prevent missing recording.

[0011]

To achieve this object, the present invention provides an ink container made of a permeable material into which ink can be visually inserted, and a non-transparent material which covers and holds the entire side surface of the ink container. In a structure of an ink container support in an ink writing recorder having a holder made of a conductive material and a pen for supplying ink from the ink container to record on a medium, the holder has a spring property and the ink container is
When it is stored, it elastically deforms to hold the ink container, and
On the side surface of this holder, a peep window extending in the direction that follows the change of the liquid level of the ink in the held ink container is provided, and a ruled line that crosses the peep window is parallel to the liquid surface of the ink. Is displayed on the holder.

[0012]

According to the present invention having the above-described structure, the ink container is held in the holder and the ink in the ink container is supplied to the pen to record on the medium. Here, when the ink container is held in the holder, the entire circumference of the side surface of the ink container is covered by the holder, but the change in the liquid level of the ink can be confirmed through the viewing window. You can check it at any time without removing it. Also, the peep window extends following the change in the ink surface, and the end of the peep window on the side where the ink surface seen from the peek window changes when the remaining amount of ink decreases. A ruled line indicating the ink replenishment timing is displayed on the side of the holder across the sighting window so that it is parallel to the ink surface that can be seen through the sighting window in the vicinity of the area. Can be done easily.

The holder 10 is made of a non-permeable material having a spring property, and is formed so that the accommodating volume for the ink container 5 is slightly small. The side surface of the holder 10 that comes into contact with the side surface of the ink container 5 when the ink container 5 is stored elastically deforms and acts on the side surface of the ink container 5.
The ink container 5 can be held at any desired position in the holder 10 by generating a frictional force between the side surface of the ink container 5 and the side surface of the ink container 5.

Reference numeral 14 indicates the ink container 5 so that the remaining amount of ink in the ink container 5 housed in the holder 10 can be confirmed.
This is a peephole that is provided by partially opening the side surface of the holder 10 so as to extend in the same direction as the change direction of the liquid surface due to the increase / decrease of ink in the inside so as to form an elongated hole shape. At least one is provided on an arbitrary side surface of the holder 10 for easy confirmation.

Reference numeral 15 is a peep near the lower end portion of the peep window 14 on the side where the liquid level of the ink in the ink container 5 visible from the long peep window 14 changes when the remaining amount of the ink becomes small. The holder 10 is arranged so as to traverse the observation window 14 so as to be parallel to the liquid surface of the ink which can be seen through the window 14.
If the liquid level of the ink drops to the position of the ruled line 15 in the ruled line indicating the time of refilling the ink displayed on the side of the, it means that the ink remaining amount in the ink container 5 has decreased to the amount to be replenished. The display position is determined so that it is visible. Here, the ink container 5 is a holder 10
The vertical position of the ink container 5 can be adjusted by adjusting the height of the holder 10 itself to adjust the vertical position of the ink container 5 in the holder 10. The adjustment amount is small because it is used for fine adjustment, and the ruled line 15 is a rough indication that the remaining ink amount has decreased to the amount to be replenished.

The method of using the ink writing recorder having the above structure will be described. First, the cap 6 is fitted into the ink container 5 containing the ink, the ventilation hole 6a of the cap 6 is covered with a finger, and the side surface of the ink container 5 is covered with a finger. When pressure is applied, the volume of the ink container 5 decreases, the internal pressure rises, and the ink rises inside the ejection pipe 7. At this time, by setting the ink container 5 to a position higher than the suction pipe 9 of the pen 2, the ink is guided to the suction pipe 9 of the pen 2 via the ink tube 8 and passes through the ink passage 2b in the pen 2. Then, it reaches the pen tip 2a, and the recording trace 4 can be drawn on the recording paper 3.

In this way, when the ink reaches the pen tip 2a, the ink container 5 is stored in the holder 10. Here, from the ink container 5 housed in the holder 10 to the pen tip 2
In order to stably supply ink to a, first, stand 1
The nut 13 screwed into the threaded portion 11a of the base 1
Then, the stand 11 is rotated and the screw portion 11a is moved up and down around the base 12 to adjust the height of the holder 10. This height is determined so that the liquid surface of the ink in the ink container 5 is always higher than the suction pipe 9, and after the height of the holder 10 is adjusted, the nut portion 13 is brought into contact with the base 12 and the screw portion 11a. Tighten against
After suppressing the movement of the stand 11 to determine the height of the holder 10, the ink container 5 is housed in the holder 10.

As a result, since the liquid level of the ink in the ink container 5 is higher than the suction pipe 9 of the pen 2, the ink passes from the ink container 5 to the discharge pipe 7 and from the ink tube 8 to the suction pipe 9. Then, the trace 4 can be drawn on the recording paper 3 by being guided to the pen tip 2a through the ink passage 2b of the pen 2.

When recording is performed in the above state, the ink is consumed from the pen tip 2a, and the liquid level of the ink in the ink container 5 is lowered. At this time, when the remaining amount of ink is large, the liquid surface of the ink is above the upper end portion of the holder 10 and can be easily viewed. When the ink is further consumed, the liquid surface of the ink is hidden by the holder 10, but the change of the ink liquid surface can be confirmed from the observation window 14 provided on the side surface of the holder 10. If the ink is consumed further and the liquid level drops to the ruled line 15,
Since that time is an ink replenishment time, the cap 6 is removed from the ink container 5 and ink is replenished. At this time, the ink may be replenished by removing the ink container 5 from the holder 10 and replacing it with a new ink container, or replenishing only the ink, or the replenishment time can be grasped without removing the ink container 5 from the holder 10. The ink container 5 may be removed from the holder 10 and the cap 6 may be removed to only replenish the ink.

[0023]

As described above, according to the present invention, the ink container is made of a permeable material into which the ink is visibly put, and the non-permeable material which covers and holds the entire side surface of the ink container. In a structure of an ink container support in an ink writing recorder having a holder and a pen for supplying ink from an ink container to perform recording on a medium, the side surface of the holder follows changes in the liquid level of the ink in the held ink container. In addition to providing a peep window extending in the direction of the direction, the liquid level of the ink visible from the peek window changes when the remaining amount of ink is low. The ruled line indicating the ink replenishment time is displayed on the side surface of the holder so as to cross the viewing window so as to be parallel to the liquid surface of the ink.

Therefore, the change in the liquid surface of the ink can be confirmed through the observation window, and the remaining amount of ink can be confirmed at any time without removing the ink container from the holder. Also, if the ink level drops to the level of the ruled line, it is the replenishment time, so there is the effect that the judgment of the ink replenishment time can be made easily, and it is easy to check the ink remaining amount. Since the replenishment time can be easily determined, the ink will be prevented from running out, and the recording will not be missed due to the ink running out at the time of recording a sudden phenomenon such as an earthquake.
