Abstract

PURPOSE:To facilitate the confirmation of accuracy by providing an operating means for selecting a specific input channel and displaying the selected channel in digital or analog or recording the selected channel thereby realizing an interlocked designating operation of a specific channel. CONSTITUTION:When the designation of a specific channel is desired, a mode selection switch 61 on an operating means 6 is depressed thus switching a normal multipoint continuous display mode to a single point continuous display mode. A channel selection switch 62 is then depressed in order to select a specific input channel. The channel number is displayed on the channel display section 51 of a display means 5 so that it can be confirmed. When a desired channel is selected, a confirmation key switch 63 is depressed and the specific channel is displayed digitally on a digital display section 52. Furthermore, a recording means 3 is shifted to a position corresponding to a predetermined measuring amount of a recording paper 4 in the breadthwise direction thereof. Since the measurement value can be determined based on the position of a pointer 3a on a scale board 2, the accuracy of measurement can be confirmed easily by providing an identical input.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recorder for taking in a plurality of input signals and recording them.

[0002]

2. Description of the Related Art A recorder which takes in a measurement input signal such as temperature and records the signal is, for example, sequentially inputting a plurality of input signals at predetermined time intervals (for example, 5 seconds) on a scale plate and then on a recording paper. To record.

[0003]

However, since most recorders that perform analog instruction or analog recording do not have a digital display means, it is necessary to check the accuracy of the analog when inspecting or checking the recorder. Then, the channel switches continuously and the measurement instruction is not constant, and it is difficult to confirm the accuracy with the analog scale plate.

SUMMARY OF THE INVENTION In view of the above points, an object of the present invention is to provide a recorder capable of continuous indicating operation for a specific channel and facilitating accuracy confirmation.

[0005]

SUMMARY OF THE INVENTION According to the present invention, in a recorder for capturing a plurality of input signals and recording on recording paper, a specific input channel is selected, and analog display or digital display or recording of that channel is performed. It is a recorder equipped with operation means for performing the operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 is a front view showing the embodiment of the present invention.

In the figure, reference numeral 1 is a case of a recorder, which has a scale plate 2 on the front surface thereof, and a pointer 3a for giving an analog instruction (display) to the scale plate 2 on a recording paper 4 in the center. A recording unit 3 for recording, a digital display unit 5 and an operating unit 6 are provided below the central recording paper 4.

That is, as shown in the block diagram of FIG. 2, the input signals e1, e2, ..., En captured at the input terminals t1, t2, ..., Tn are input to the switches S1, S2 ,. ,, Sn is sequentially selected and fetched,
The signal is amplified by the amplifier 8 by a predetermined factor, converted into a digital signal by the AD converter 9, and stored in the memory 11 by the processing device 10 such as a microcomputer. And this signal is
After the predetermined processing, it is digitally displayed on the display means 5, and the recording means 3 is driven to sequentially record predetermined positions on the recording paper 4. The processing device 10 also controls the feeding of the recording paper feeding device 12, and also controls the input switching device 7, the gain of the amplifier 8, the AD converter 9, and the like.

Referring again to FIG. 2, when it is desired to obtain an instruction or the like for a specific channel, for example, by pressing the mode selection key switch 61 of the operation means 6, the normal multi-point continuous display mode is switched to the one-point continuous display. Switch to mode. Then, by pressing the channel selection key switch 62, a specific input channel is selected. This channel number can be confirmed by displaying it on the channel display section 51 of the display means 5. If this number is acceptable, by pressing the confirmation key switch 63, the digital display of the specific channel is displayed on the digital display section 52, and the recording means 3 corresponds to a predetermined measurement amount in the width direction of the recording paper 4. The measurement value can be known by moving to the position where the pointer 3a is located on the scale plate 2, and the measurement accuracy can be easily confirmed by giving the same input.

In the case of this one-point continuous display, the recording operation of the recording means 3 is not normally performed, but by turning on the operation switch 60, the recording paper feeding device 12 is driven and the recording paper 4 is fed to perform recording. Recording can be performed by the means 3 and one-point continuous recording can be performed.

If the digital display means 5 is not provided, the scale plate 2 and the pointer 3a of the recording means 3 can perform only analog display, and recording and display in various modes are possible. The recording method of the recording means 3 is analog,
Various types such as digital are conceivable, and the recording means 3
The driving method may be either an automatic balancing method or a raster scan method.

Further, when the point 50 of the channel number display section 51 of the display means 5 is blinking, multi-point continuous display,
When it is not blinking, it can be distinguished by displaying it as one-dot continuous display.

[0013]

As described above, the present invention can perform analog display, digital display, or recording of a specific input channel. It is possible to give sufficient time for the input instruction, and it is possible to easily check the scale accuracy, check, and confirm the accuracy of the configuration. Also, if necessary, it is possible to display multiple points continuously after a certain channel has reached a predetermined measurement value, or to instruct and record a specific channel, and to use a recorder with various functions. can do.
