Description

[Detailed Description of the Invention] The present invention relates to a moving indicator device for a recording pen in a two-pen recorder.

For small 2-pen recorders, the entire recording device is housed in a box-shaped protective case, and only one end of the protective case is covered with a transparent lid, so it is difficult to move the recording pen during recording. It is difficult to observe the condition directly.

However, when using this type of recorder in practice, it is often necessary to check the movement status of each recording pen or to partially read recorded data.

For this reason, in conventional two-pen recorders, both indicators were placed on the front of the scale, but due to its configuration, one recording pen protruded from the front of the scale, and this caused a connection with the other recording pen. Since it hides the index attached to the front of the scale and the scale attached to the front of the scale, there is a drawback that the error in reading the display and value becomes large.

In view of the above-mentioned circumstances, the present invention has been designed so that the movement status of two recording pens can be observed at a glance during recording work, and if necessary, recorded data can also be partially read from the movement distance of the recording pens. This is intended to provide a moving marking device for a recording pen, and this will be explained in detail based on an embodiment shown below. 1 is a main body frame of a skewer device, 2 and 3 are the same vertical plane. Guide rods 4 and 5 are horizontally suspended on the main body frame 1 so as to be positioned at appropriate intervals vertically within the body frame 1; 6 is a scale plate attached to the front surface of the main body frame 1 and has a suitable scale 6a on its surface;
7 is a pen holder that is slidably mounted on the guide rod 2 and has an indicator 7a hanging down from the front end across the upper edge of the scale plate 6; 8 is a recording pen that is removably attached to the pen holder 7; , 9 is a pen holder slidably mounted on the guide rod 3, 10 is a recording pen removably attached to the pen holder 9, 11, 12, 13, 14.
．． ．． Reference numerals 15 and 16 refer to pulleys rotatably supported on the body frame 1, Q pulleys 17 and 18 each fixed to the main shaft of a not-shown potentiometer attached to the body frame 1, and 19 a pulley fixed to the drive pulley 17. Wound and driven pulley 17. Pulley 11.13
A belt 20 made of wire, thread, etc., which is hung between and connected to the pen holder 7, is wound around the drive pulley 18 and is connected to the drive pulley 18. This wire is hung between the pulleys 12 and 14 and is connected to the pen holder 9.
A belt 21 consisting of a system, etc. is wound once around the drive pulley 18 and is connected to the drive pulley 18. Pulley 12.15,16
．． A belt 22 made of wire, thread, etc. is hung between the recording pen 10 and the scale plate 6 and moves along with the belt 20;
An indicator 23 is connected to a belt 21 in a manner such as shown in FIG. This is a drum for feeding the recording paper 24.

In this case, the support beams 4 and 5 are connected to each recording pen 8 and 1 in the recording state.
This serves to support each pen holder 7.9 so that the zero pen tips 8a, 10a contact the recording paper 24 with appropriate pressure.

Further, the pulleys 12, 14 and the driving pulley 18 are constructed as two-stage pulleys each having the same diameter as illustrated in FIG. lj
, 20 and 21 are selected such that they are located in parallel horizontal planes at different heights.

Since the present device is configured as described above, each recording pen 8, 10 can be moved when the drive boob IJ-17, 18 is operated to the right or to the left depending on the measurement input introduced through the known device. move to the left or right, respectively, and draw continuous recording lines on the recording paper 24.

In this case, each index 7a and 22 moves on the scale plate 6 integrally with or in a position corresponding to the recording pens 8 and 10, so that the moving state of the recording pens 8 and 10 can be easily observed even from the outside. Recorded data can also be read by using the scale 6a.

As described above, according to the present invention, the movement state of each recording pen can be observed extremely reliably as needed even when the recorder is set in a two-pen recorder, so that the recorder can be easily monitored. 1z It is possible to easily discover malfunctions and abnormalities in the recording pen.Since all indicators can be placed close to the scale, recorded data can be easily read visually if necessary, which is extremely useful in practical use. A convenient two-pen recorder can be provided.

Furthermore, since the device of the present invention has a simple structure, there is no particular cost increase compared to a conventional two-pen recorder.
