Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recorder capable of arbitrarily selecting the function of the device itself.

[0002]

2. Description of the Related Art There are general-purpose recorders of different types according to various functions such as input of recording object and recording method on recording paper. That is, a type having a part of an input section corresponding to various input targets, a type having an input section corresponding to all assumed input targets, a type using recording paper in the recording method, and a screen display. There are some types that do. Therefore, current recorders are either preconfigured with the minimum configuration or with all features.

[0003]

However, when the internal configuration of the recorder is further classified and examined by function, first, the input signal forms from various measurement targets to be applied are different in DC / AC and signal There are differences in level, differences in digital / analog, etc., a converter and an arithmetic circuit adaptable thereto are required, and various recording and display forms desired by the user are included. ..
However, current recorders have not been able to provide a recorder having only the functions required by each user. For this reason, the user has to use the recorder in a relatively limited application range, or even in this case, there is an inconvenience that the user has to select a model having a considerably high grade. This results in high costs for the user.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a recorder capable of forming a recorder having only the functions desired by a user and reducing the cost.

[0005]

In order to achieve the above-mentioned object, the present invention provides an arithmetic unit A in a device box 1, and a signal input unit B and a recording unit C are electrically connected to the arithmetic unit A. The recorder A is a first unit configured such that the main control system board 7 and the function control system board 8 attached to the main control system board 7 can be removably attached to the motherboard 3. Yes, the signal input section B
Is a second unit equipped with signal converters 11a and 11b for each channel corresponding to various measuring devices. The recording section C is a chart print recording unit 9 which can be selectively connected to the arithmetic section A, and a hardware unit. The disk drive 9a for the recording unit or the video display unit 15 is featured.

[0006]

Therefore, by additionally incorporating the control system boards 7 and 8 for each desired function in the arithmetic unit A as the first unit, and in the signal input unit B as the second unit. , Signal converter 11 for each required function
By incorporating a and 11b, it is possible to replace the chart printing recording unit 9 in the recording display form requested by the user, the disk drive 9a for the hard recording unit, and the image display unit 15 in the recording unit C. Assembled parts can be realized without waste, and the recorder can be provided at an appropriate cost corresponding to the function desired by the user.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view of the recorder, and FIG. 2 is an exploded perspective view showing the recorder from the back side. In these drawings, reference numeral 1 is a device housing, and its front and rear ends are open. In addition, the inner unit 2 which is similarly opened at the front and the rear is removably fitted and inserted into the device housing 1.

In the internal unit 2, the arithmetic unit A of the present invention is constructed as a first unit. That is, a mother board 3 is detachably mounted in the internal unit 2, and the mother board 3 is located at the front and rear,
Connectors 4 and 5 for connecting signal cables are provided. Further, board connecting terminal members 6 (6a, 6b, 6c) are provided at a predetermined pitch in the central portion, and the board connecting terminal member 6 includes a main control system board 7 including a CPU and an accessory member for the main control system board 7. Each terminal of the function control system board 8 (8a, 8b, 8c) for each function, for example, for communication modem, for each channel calculation, for each record display function, and for storing floppy disk is detachable.

Further, at the front open end of the apparatus casing 1,
As the recording unit C, a chart printing recording unit 9 such as a dot printing type, a pen type, or a dot printing and character printing type (hybrid type) is arranged. The chart print recording units 9 of the respective methods are individually prepared and have the same outer shape that can be exchangeably connected to the apparatus housing 1. Further, instead of the chart print recording unit 9, a disk drive 9 for storing a floppy disk is provided.
It is also possible to connect a. In this case, the image recording unit 15 and the data analysis software may be separately prepared so that the chart can be displayed as an image.
Alternatively, a display unit may be connected as the recording unit C to directly visually recognize the recording result. Each unit is provided with a connector 4a at the end of the flexible printed wiring board 10, and the connector 4a is connected to the arithmetic unit A via the connector 4 of the motherboard 3. A keyboard for operation setting is separately attachable to and detachable from the motherboard 3 of the unit.

Further, at the rear open end of the apparatus casing 1,
The signal input section B is detachably connected as a second unit. The signal input section B includes a signal converter 11a compatible with various measuring instruments. The signal converter 1
1a is, for example, a DC current input of 4 to 20 mA, 0-1
Digital signal converters corresponding to function-specific channels such as DC current input of 00mA, DC current input of 5V, thermocouple signal input, resistance value signal input, etc. are configured individually or in combination, and each input signal is configured. The corresponding input terminals 12 and 13 for each channel are provided. The signal converter 11a may be detachably mountable with an input conversion board for each function and a conversion circuit board for signal linearization, and may be equipped with a channel selection key. Further, in the case of DC signal input, the power supply unit may be equipped.
The AC signal converter 11b may include, for example, an input / output terminal unit 14 for a communication cable. In each of the signal converters 11a and 11b, the connector 5a connected to the connector 5 of the arithmetic unit is connected via the flexible printed wiring board 15.

In such a configuration, the system board can be selected and combined in the arithmetic unit according to the user's request, the input signal type can be selected in the signal converter 11, and the recording can be performed. Since a combination of display units can be selected, it is possible to realize a hybrid configuration that is optimal for the user's request and to minimize the cost by simply preparing a relatively small number of various parts and units.

[0012]

According to the present invention, the signal input unit, the arithmetic unit, and the recording / display unit are unitized, and the units and blocks can be freely combined to constitute the exchange functionality of each unit.
There is an effect that it is possible to construct a recorder in a form that is closest to the user's request at a low cost by simply preparing a relatively small number of types of parts that are excellent in capacity conversion.
