Description

[Detailed description of the invention] This invention relates to a recorder that performs analog recording of measured quantities.

In conventional analog recorders, a recording mechanism such as a recording pen or a marking mechanism records a measured amount on a recording paper.

The amount of measurement recorded was read based on the position of the pointer provided on the recording mechanism on the scale plate.

However, since it has to rely on visual inspection, it has the disadvantage that it is not possible to accurately read the measured amount.

Moreover, in a multi-pen recorder, a recording mechanism must be provided with a scale plate for the number of pens and a pointer, which causes reading errors.

The purpose of this idea was made in view of the above points.
It is an object of the present invention to provide a recorder capable of performing analog recording of a measured quantity on recording paper by a recording mechanism and digitally displaying the measured quantity by a digital display.

FIG. 1 is a front view of a three-pen recorder showing the first embodiment of this invention.

1 is the outer box of the recorder, 21°22.23 is the 1st. Second. Third scale plate, 31, 32.3
3 has a pointer 311, 321, 331° and a recording pen 312, 322, 332, respectively. 2nd゜3rd
4 is a recording paper, 5 is a recording paper feed sprocket that feeds the recording paper 4 forward, 6 is a recording paper presser,
7 is a digital display, 8 is a first . Second. The first step selects the measured amount of the third pen and displays it on the digital display 7. Second. The third pushbutton switch 81.92.93 is the first switch. Second. The first pen corresponds to each input specification of the third pen. Second. This is the third range unit.

When in operation, the recording paper 4 is fed forward by the recording paper feed sprocket 5, and each recording pen 312, 322 of each recording mechanism 31, 32, 33 records the measured amount corresponding to each measurement point on this recording paper 4. , 332, and each scale plate 21° 22 by each pointer 311, 321, 331.
．． 23, the measurement amount is instructed.

At this time, if you select which pen you want to see the measurement quantity instruction for by using the switch 8 by pressing the pushbutton switch 81, 82, or 83, the digital display 7 will display the digital measurement quantity for the selected location. Get instructions.

It is possible to give a digital instruction for a measurement quantity at one location in advance, or it is also possible to make a digital instruction for an arbitrary location at an arbitrary time.

FIG. 2 is a front view of a four-pen recorder showing a second embodiment of this invention.

The same reference numerals as in FIG. 1 indicate the same components, 34 is the recording mechanism of the fourth pen, 71°72.73.74 is the first pen that digitally indicates the measured amount corresponding to each pen. Second. Third. A fourth digital display, 94, represents a fourth range unit for a fourth pen.

In other words, an analog record is obtained for each pen on the recording paper 4, and a digital indication of the measured amount for each pen is always obtained separately from the plurality of digital displays 71, 72, 73, 74.

FIG. 3 is a front view of a multi-location recorder showing a third embodiment of this invention.

The same symbols as in FIG. 1 indicate the same components, 2 is a scale plate,
3 is a multi-point recording mechanism consisting of a marking mechanism; 70 is a point number display; 7 is a digital display; 8 is a plurality of points for selecting each measurement point and digitally displaying the measured amount on the digital display 7; This is a switch consisting of a group of switches.

This switch 8 is used to select the location at which the measured quantity is desired to be displayed.

Then, an analog record of each location is obtained on the record sheet 4, and the location number display 70 displays the location number of the selected measurement location, and the digital display 7 provides a digital indication of the measured quantity at that measurement location. be able to.

Further, by operating the switch 8, it is also possible to record each measurement location and simultaneously issue instructions sequentially.

As detailed above, this device has a recording mechanism for analog recording of the measured quantity on recording paper and a digital display for digitally indicating the measured quantity in separate locations, and is further equipped with a switch to select the display location. It is a recorder.

Therefore, since it is possible to obtain a digital indication of the current measured quantity together with the analog recording result, it is possible to read the measured quantity more accurately without individual differences compared to analog instructions.

In addition, in the case of a multi-pen recorder, if you select the measurement amount for each pen with a switch and have it indicated on one digital display, or if you install a digital display for each pen, you can set the indicator for each pen. It is possible to significantly reduce space when using multiple pens such as 6 pens or 12 pens without requiring a dial or scale plate.

Furthermore, if a multi-location recorder is used to provide a digital instruction for each location along with the location number, there is no need to include a recording location display mechanism in the recording mechanism such as a marking mechanism, and the recording mechanism can be made that much simpler. .

Further, if digital instructions are given along with analog instructions from the pointer and scale plate as in the past, reading can be performed as required.
