Description

[Detailed description of the invention] This invention is a recording paper feeding mechanism (hereinafter simply referred to as feeding mechanism).
This invention relates to a pen-lifting device for a recorder having a structure in which the pen is opened forward around a shaft fixed to an internal device to allow recording paper to be loaded and replaced.

In some pen lifting devices of this type, the pen lifting operation is not independent from the opening operation of the feed mechanism, so the pen lifting operation cannot be performed separately; This can be done independently, regardless of the opening operation of the feeding mechanism, but since the pen lifting operation starts at the same time as the feeding mechanism is opened, the feeding mechanism starts moving before the pen tip is far enough away from the recording paper, and the recording The paper may drag the pen and cause recording errors.

The present invention eliminates these drawbacks and provides a pen-lifting device for a recorder that allows the feeding mechanism to be easily released after lifting the pen, and also allows the pen-lifting operation to be performed independently, regardless of the feeding mechanism. This is what we provide.

The drawing is an explanatory configuration diagram showing the main parts of the embodiment of the present invention. FIG. 1 shows a state in which the feeding mechanism is stored in the meter, the pen lifting device and the feeding mechanism are locked, and recording is possible.

In the figure, reference numeral 1 denotes a feeding mechanism which has a recording paper storage box 2 at the rear, and the recording paper 3 stored in the storage box 2 is sent forward by a recording paper feeding drum 4 and stored in a lower part 5.

Further, this feeding mechanism 1 is supported so as to be rotatable in the front and rear directions around a shaft 6 fixed to the internal device, and when opened forward, the recording paper 3 can be replaced.

7.8 is the first. In the second pen, the first pen 7 has a first main shaft 9,
The second pen 8 is attached to the first slider 11, which moves left and right on the first auxiliary shaft 10, and the second slider 14, which moves left and right on the second main shaft 12 and second auxiliary shaft 13, uses the recording paper by its own weight or the force of a spring. 3 so that recording can be done with an appropriate pen pressure.

15 and 16 are respectively the 1st. Use the second pen lift lever to move the first and second pen up levers respectively. Rotatably supported by the second main shafts 9 and 12,
A rotational force is applied in the direction indicated by arrows A and B, respectively, and the stoppers are locked at two positions, ie, stoppers 17.18 and 19.20, respectively.

21 and 22 are respectively the 1st. The second pen lifting shafts are rotatably supported by the 1st and second main shafts 9 and 12, respectively, and receive rotational forces in the directions of arrows C and D due to their own weight or spring force, respectively. It comes to rest at a position in contact with a protrusion 23.24 fixed to the second pen up lever 15.16.

Furthermore, arms 211 and 221 are provided at the ends of the first and second pen lifting shafts 21 and 22, respectively, and are long in the lateral (perpendicular to the drawing) direction.
．． A slight gap is maintained with the second pen 7.8.

Reference numeral 25 is a link, and a second stage arm 253°2 which is long in the horizontal (perpendicular to the drawing) direction is attached to the end of the first stage arms 251 and 252, respectively.
54, and the first spring 26 applies an upward force indicated by arrow E to the lower end 255.

Reference numeral 27 denotes a clamp lever rotatably supported by the internal device or the feed mechanism 1. A downward force in the direction of arrow F is applied by the second spring 28, and a recess 271 provided at the tip of the lever 27 engages the clamp pin 29. engage.

That is, this state is a clamp state, and at this time the link 25
The tip 272 of the clamp lever 27 pushes the protrusion 256 downward in the direction of arrow E against the force of the first spring 26 to suppress the force of the spring 26, and the second stage arm 253, 254 of the link 25 are the first. Second pen lift shaft 21
．． 22, or is held with a slight gap between them.

Therefore, the arms 211 and 221 of the pen raising shafts 21 and 22 are the first and second arms, respectively. The first pen 7.8 is slightly apart from the second pen 7.8. Second
Since the pen 7.8 contacts the recording paper 3 with an appropriate pen pressure, the first. It is possible to record on the recording paper 3 with the second pen.

In addition, 30.31 is the elongated hole 257, 25 of the link 25, respectively.
The height of the link 25 in the vertical direction, that is, in the direction of the arrow E, can be adjusted by loosening the guide pins 30 and 31 inserted in the guide pins 8 and 8.

Since the pen lifting device of the present invention has such a structure, as shown in FIG. Then, the recess 271 is disengaged from the clamp pin 29, the tip 272 is separated from the protrusion 256 of the link 25, and the restraining force on the first spring 26 is released.

That is, at this time, the clamp is released and the link 25
is pushed up in the direction of arrow E by the force of the first spring 26, and the arms 253 and 254 of the second stage of the link 25 push up the pen lifting shafts 21 and 22 in the directions of arrows H and J, respectively.

As a result, the arms 211.degree. The second pens 7 and 8 are pushed up and separated from the recording paper 3 together.

At this time, if the clamp lever 27 is supported by the internal device, remove the clamp (not shown) for the feed mechanism 1, put your hand on the feed mechanism 1, and pull it toward you, and the clamp lever 27 1, the clamp lever 27 will release the clamp on the feeding mechanism 1 at the same time as the pen lifting mechanism, so the clamp lever 27 will be released.
By pulling 27 towards you, the feeding mechanism 1 can be easily opened forward and the recording paper 3 in the storage box 2 can be replaced.

When replacing the recording paper 3 and starting recording again, push the clamp lever 27 or the feed mechanism 1 backward to close the feed mechanism 1, and hold the end 273 of the clamp lever 27 to push the recess 271 into the clamp pin 29. When the feed mechanism 1 is clamped, the protruding portion 256 of the link 25 is pushed by the tip 272 of the clamp lever 27 at the same time, and the clamping state shown in FIG. 1 is easily established. The second pen 7.8 can touch the recording paper 3 and record.

Furthermore, the first. When it is desired to separate the second pens 7 and 8 individually from the recording paper 3, as shown in FIG. The second pen lift shaft 22 is pushed up in the direction of arrow M by the protrusion 24 fixed to the pen lift lever 16, and the second pen 8 is rotated in the direction of arrow M by the arm 221 of the second pen lift shaft 22. Pen 8 easily prints recording paper 3 on its own
be separated from

Further, when the first pen lifting lever 15 is removed from the stopper 17 and rotated, the first pen 7 is similarly separated from the recording paper 3 by itself.

As is clear from the above explanation, when according to the present invention,
By operating the clamp lever, you can easily release the clamp on the pen lifting mechanism and release all the pens at the same time, and then the feeding mechanism is pulled forward, so you can leave the feeding mechanism as it is and remove all the pens at the same time. Of course, when the feeding mechanism is opened forward, the pen is not dragged by the recording paper and unnecessary recording is not left on the recording paper, unlike in the conventional case.

Also, when a clamp lever is attached to the feeding mechanism, not only does it have the same effect, but when the pen lifting mechanism is released from the clamp, the feeding mechanism is also released at the same time, allowing all pens to be raised and fed at the same time with one clamp lever. It is even more convenient because the mechanism can be opened forward and pulled out.

In the above embodiment, each pen can be separated from the recording paper individually, and the effect is extremely large.
