Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a data processing device for a measuring instrument.
More specifically, the present invention relates to a data processing device in which a data processor and a printer, which process and output measurement signals from a measuring device in a predetermined manner, are configured to be connectable and separable.

[Background Art and Problems Therewith] A data processing device is usually relatively large because it includes an operation section, a calculation section, an input/output section, a display section, a printer, and the like.

By the way, in the field of measuring instruments, in contrast to the conventional mechanical scale reading method, there are new methods that incorporate optical or capacitive encoders into the measuring instrument body and display measurement results digitally and/or analogously. So-called electronic measuring instruments are also becoming widespread.

However, with both mechanical scale reading measuring instruments and electronic measuring instruments, the inspector records the measurement results in a notebook.
In order to use this as data for quality control, etc., it must be calculated manually using a calculator or input into a computer and processed. Therefore, in either case, work efficiency is extremely poor.

Therefore, we installed an input/output circuit for this type of measuring device.
It is also conceivable to configure the measurement value so that it can be transmitted directly to the data processing device. However, even with this configuration, there are the following problems.

If the measuring instrument and data processing device were directly connected, the whole device would have to be carried to the measurement site, which would defeat the purpose of a portable measuring instrument. In other words, this results in a reduction in measurement work, and even in some cases makes measurement impossible.

Even if the data processing equipment is made as small as possible,
As long as the two are directly connected, the printer must also be integrated, so the weight cannot be reduced that much since the power supply for the printer consumes the largest amount of power in the system. Furthermore, it is necessary to prepare as many data processing devices as there are measuring instruments.

When a certain measurement item is measured in sections using a plurality of measuring instruments, unless the sections are measured by all the measuring instruments, the measured values cannot be seen at all unless one visits the measurement site. That is, since immediate evaluation is not possible, the data cannot be used as feedback data to the processing machine that obtains the object to be measured.

This is a common problem not only with measuring instruments but also with general data processing devices to which external signals are input, such as those that receive detection signals from other machines and process the data.

[Purpose of the invention] The purpose of the present invention was to solve these conventional problems.It is convenient to carry, allows for easy connection work, and prevents erroneous operation when connected. It is an object of the present invention to provide a data processing device for a measuring instrument that can improve operability with minimal effort.

[Means and effects for solving the problem] Therefore, in the present invention, a printer that consumes a large amount of power (in the case of a battery, it becomes large and heavy due to the large battery) and a data processor that includes a calculation section, etc. In addition to making it possible to combine and separate the main unit, each has its own power supply system and is configured to be able to operate independently.Moreover, when the two are combined, both power supply systems are automatically unified, and either one of the power supply on/off switches can be used. The above object is achieved by configuring the device so that the entire device can be started and stopped by the following steps.

Specifically, it has a first power supply connection terminal, a first power supply on/off switch, a signal input terminal and a data output terminal for connecting a measuring instrument capable of transmitting a measurement signal to the outside, and through the signal input terminal. a data processor that processes the input measurement signal from the measuring device in a predetermined manner and outputs it through the data output terminal; a second power connection terminal; a second power on/off switch; and a data input terminal; A printer that outputs output data from the data processor input through a terminal in a predetermined format is configured to be mechanically connectable and separable, and on each coupling surface between the data processor and the printer,
When the data processor and the printer are mechanically coupled, the data output terminal and the data input terminal are arranged in correspondence so that they are connected to each other when the two are mechanically coupled. In order to prevent one of the first and second power on/off switches from being exposed to the outside, one of the power on/off switches is provided on the coupling surface, and an electric circuit switch for unifying the power supply system of the data processor and the printer is coupled to both sides. The data processor and the printer are arranged in correspondence with each other, and the data processor and the printer are integrated and activated by the other power on/off switch, and output data from the data processor is printed out on the printer. It is said that

[Example] FIG. 1 shows a data processing device for a measuring instrument according to this example. The data processing device for the measuring instrument includes a data processor 11 that receives a measurement signal from a measuring instrument, processes the measurement signal in a predetermined manner, and outputs it, and prints out the output data from this data processor 11 in a predetermined format. It consists of a printer 21. These two parts are configured to be connectable and separable from each other, for example, by a plug-in structure in which one side has a convex part and the other side has a concave part.

As shown in FIG. 2, the housing 12 of the data processor 11 is provided with an operating section 13 with various key switches arranged on its top surface and a digital display section 14, as well as an arithmetic section 15A and a storage section inside. 15B is built-in. The calculation unit 15A is
Processes the received measurement signal according to a preset procedure, displays it on the display section 14, and stores it in the storage section 15.
It has a function of storing data in the storage section 15B and outputting the data in the storage section 15B to the outside. Note that the calculation unit 15A
It has been made into a unit and can be replaced with one with other functions. Also, on the rear surface of the housing 12, there is a first power connection terminal for connecting an external power supply.
A first signal input terminal _I 1 to which a measuring device T ₁ and a micrometer 31 are connected is respectively provided. When an external power source is connected to the first power supply connection terminal _T1 , the data processor 11 becomes able to operate independently. The micrometer 31 has a function of transmitting measured values to the outside by operating a data transfer switch 32. Furthermore, the housing 1
A first power on/off switch SW ₁ , a data output terminal J ₁ and one electric circuit switch C ₁ are provided on the coupling surface, that is, the side surface, which is coupled with the printer 21 of No. 2.

As shown in FIG. 3, the housing 22 of the printer 21 has an operating section 23 and a cutter 2 on its top surface.
4 is provided, and an operation section 23 is provided inside.
A printer control section 25A that drives the printing mechanism based on commands from the printer and a storage section 25B are built in. The printer control unit 25A edits the output data from the data processor 11 into a predetermined format and stores it in the storage unit 25B,
The printing mechanism is operated based on the data in the storage section 25B. Further, a second power supply connection terminal T ₂ for connecting an external power supply is provided on the rear surface of the housing 22 , and a second power supply connection terminal T 2 is provided on the side surface opposite to the connection surface with the data processor 11 .
A power on/off switch SW ₂ is provided for each. When an external power supply is connected to the second power supply connection terminal _T2 , the printer 21 becomes able to operate independently. Furthermore, the data processor 11 of the housing 22
The first data output terminal J _{1 is connected to the first data output terminal J 1}
A data input terminal _J2 is disposed at a position corresponding to the above-mentioned _one and electrically connected thereto, and the other electric circuit switch C2 is arranged at a position corresponding to the one electric circuit switch _C1 and electrically connected thereto. is installed. The electric circuit switches C ₁ and C ₂ have, for example, a limit switch structure that is turned on by the coupling force when the data processor 11 and the printer 21 are integrally coupled.

When the data processor 11 and the printer ₂₁ are connected to each other, as shown in _FIG .
The power supply systems for the data processor 11 and the printer 21 are unified, that is, the power from the external power supply connected to the second power connection terminal T ₂ is supplied to each circuit of the data processor 11 in addition to each circuit of the printer 21. Both power supply systems can be turned on and off using the second power on/off switch _SW2 . At this time, since the first power on/off switch _SW1 provided on the data processor 11 side is turned on by the coupling surface of the printer 21, this first power on/off switch SW1 is turned on by the coupling surface of the printer 21.
A second power on/off switch SW ₂ provided on the printer 21 side is connected between SW ₁ and the display section 14 and calculation section 15A to make the on/off state of the first power on/off switch SW ₁ irrelevant. An interlocking interlock switch SW ₃ is inserted.

Next, how to use this embodiment will be explained.

First, with the data processor 11 and the printer 21 separated from each other, the data processor 11 is carried to the measurement site, and the first power connection terminal _T1 of the data processor 11 is connected to an external power source, and the first signal Measurement is performed by connecting a measuring device, that is, a micrometer 31, to the input terminal _I1 . In measurement, when the data transmission switch 32 is pressed after setting the object to be measured on the micrometer 31, the measured value measured by the micrometer 31 is transmitted to the calculation unit 15A through the first signal input terminal _I1 of the data processor 11. transmitted to.
The calculation unit 15A sequentially takes in the measurement values transmitted from the micrometer 31, and when a plurality of preset measurement data are taken in, calculates them to obtain quality control data. For example, a maximum value, a minimum value, an average value, a histogram for understanding the variation in measurement data, a control chart, etc. of a plurality of measurement data are obtained, and these are stored in the storage unit 15.
Store it in B.

After the measurement work at each measurement site is completed in this manner, the data processor 11 is brought to a predetermined location such as a control room and connected to the printer 21. Then, since the external power supply is connected to the second power supply connection terminal _T2 of the printer 21, when the second power on/off switch _SW2 is turned on, power from the external power supply is supplied to each circuit of the printer 21. Along with
Data processor 11 through circuit switches C ₁ and C ₂
It is also supplied to each circuit. In this state, the quality control data stored in the storage section 15B of the data processor 11 is transferred to the printer control section 2 of the printer 21 through the data output terminal J ₁ and the data input terminal J ₂ .
Output to 5A. The printer control unit 25A edits the provided data into a predetermined format and stores it in the storage unit 25B, and then or after storing the output data from the plurality of data processors 11,
Print these out.

On the other hand, when measuring small parts, the small parts can be brought to the measuring instrument and measured, so the data processor 11 and printer 21 can be handled in a state where they are connected to each other from the beginning.

Therefore, according to this embodiment, the data processor 11
and the printer 21 can be combined and separated,
Moreover, since these are configured so that they can be operated independently, even when performing measurements at the measurement site, it is only necessary to carry the relatively small and quantifiable data processor 11. Since there is no need to carry the printer 21, it is extremely convenient to carry and does not reduce work efficiency.

Moreover, in a state where the two are separated, while the data processor 11 is used for measurement, the printer 21 can be used independently for other purposes. Furthermore, since the printer 21 is provided with a storage section 15B, it is possible to sequentially store data from a plurality of data processors 11 and then output the data all at once to the printer.

Furthermore, when the data processor 11 and the printer 21 are mechanically coupled, both power systems are automatically unified, and both can be started and stopped only by the second power on/off switch SW ₂ on the printer 21 side. Since the configuration is configured so that the power on/off switches for the data processor 11 and the printer 21 are operated separately, operability can be improved. This, that is, the ability to start and stop using the power on/off switch SW ₂ on the printer 21 side means that if you prepare at least one data processor 11 equal to the number of measuring instruments, the printer 21
It has the advantage of being able to be used in common.

Furthermore, since the first power on/off switch _SW1 on the data processor 11 side is not exposed to the outside, it can be operated reliably with fewer erroneous operations, and can also be expected to be dust-proof and liquid-proof.

Further, since the data output terminal J ₁ of the data processor 11 and the data input terminal J ₂ of the printer 21 are also connected to each other, it is possible to eliminate the work of connecting them. Therefore, the joining operation can be easily performed.

Note that if a recess 26 is provided on the connecting surface side of the printer 21 to hide the first power on/off switch SW ₁ of the data processor 11, as shown by the dashed line in FIG. power on/off switch
Since SW ₁ is not turned on, there is no need to provide the interlock switch SW ₃ in FIG. 4.

The printer 21 is also provided with a second signal input terminal _I2 similar to the signal input terminal _I1 of the data processor 11, as shown by the dashed line in FIG. If it is possible to connect a measuring device, the measured values obtained with the measuring device can be directly printed out. Furthermore, the printer 21 may not be provided with the storage section 25B, and the printers may be sequentially output.

In addition, batteries B ₁ and B ₂ are built into the data processor 11 and the printer 21, respectively, as shown by the dashed lines in FIG. Good too. This is particularly convenient for carrying. Furthermore, when the data processor 11 and printer 21 are combined, it is also possible to charge the battery B ₁ on the data processor 11 side. In this way, reliable operation can be achieved without having to check the battery after separating the two. can be guaranteed.

Furthermore, the mechanical configuration that allows the data processor 11 and printer 21 to be combined and separated is as follows:
The structure is not limited to the plug-in structure described in the above embodiment, but any structure that can be combined and separated may be used.

Further, in the above embodiment, the first power on/off switch _SW1 is provided on the coupling surface of the data processor 11 so that it is not exposed to the outside when the two are coupled, and the second power on/off switch _{SW2 is provided with the first power on/off switch SW1} . I tried to turn both power systems on and off, but
A second power on/off switch SW ₂ is provided on the connecting surface of the printer 21 so that it is not exposed to the outside, and the first power on/off switch SW ₁ is used to turn on and off the power systems of both. You can.

Further, in the above embodiment, the electric circuit switch has a limit switch structure that is activated by the coupling force when the data processor 11 and the printer 21 are integrally coupled, but this may be a connector or the like.

In the above embodiment, a data processing device for a measuring instrument has been described, but the present invention can also be applied to a general data processing device to which an external signal is input, such as receiving a detection signal from a processing machine and processing the data.

[Effects of the invention] As described above, the present invention provides a data processing device for a measuring instrument that is convenient to carry, allows for easy connection work, and improves operability with fewer erroneous operations in the connected state. can do.
