Has become.

[0003]

[Problems to be solved by the device]

 With the multi-functionalization of electronic scales, operators can use various functions such as, for example, simply measuring the weight of a weighed item, measuring the number of parts such as screws, and checking whether the distributed and stored weighed item has a set weight. You can do it. These various functions are displayed on the display unit that displays the weight of the electronic scale. More specifically, by operating the keys, for example, "CAL" is displayed when the setting items are calibration, "COUNT" is displayed when the number of items is measured, and "TIME" is displayed when the clock is displayed. However, as the functions of the electronic scale increase, it is not always easy for the operator to remember all the functions of the electronic scale, and pressing a key causes the function display to be sequentially displayed to select a desired function. Moreover, it is necessary to confirm the function, and it is not always easy to effectively use these various functions.

Further, with the diversification of the functions, various display parts of the display body are also diversified corresponding to the functions. Therefore, the arrangement of these display parts is devised to facilitate the confirmation, and Care must be taken to prevent misidentification. On the other hand, since the electronic scale itself tends to be downsized, the size of the display body for displaying these is naturally limited, and it is necessary to consider this point when arranging the various display parts.

[0005]

Means for Solving the Problems The present invention has been constructed in view of the above-mentioned demands, and a main display portion such as a weight display is arranged in the center of the display body in a horizontally long size so as to be easily visually recognized. A unit display unit for displaying the unit of weight displayed by being connected to the main display unit is arranged. Further, a setting item display unit for displaying setting items is arranged on at least one of the upper and lower sides of the main display unit, and an analog display unit for displaying the outline of the load state on the electronic scale graphically in the vicinity of the display unit. Are placed.

[Action]

 When a predetermined setting is made to the electronic scale by an input means such as a key, a keyword indicating a predetermined setting item is lit on the setting item display section, or a light corresponding to the keyword is lit. Also, if there is data to be output from the electronic scale regarding the setting items, this data is output to the main display section. Furthermore, when measuring the weight of a weighed product, it takes a certain amount of time to output the measured data due to averaging of the measured data, etc. In this case, an approximate load of the weighed product on the device is analyzed. Display on the display.

【Example】

 Embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 shows a plane of a display body according to the present invention. This display is fitted in the display of the electronic scale (usually the keys for making various settings are arranged close to each other). A fluorescent display tube or liquid crystal is used as the display medium.

Reference numeral 1 indicates a display body, and the display body 1 is adapted to be fitted into the display portion of the electronic scale. Of the display body 1, a portion indicated by reference numeral 2 is a large display unit (hereinafter referred to as “main display unit”) for displaying measurement data, various setting items, and the like. It is designed to be illuminated with green, blue, etc.

Reference numeral 3 denotes a unit display unit which is connected to the main display unit 2 and is arranged side by side, and is a unit showing what unit system the weight of the object to be measured is displayed. As the unit of weight, the gram "g" in the metric system is the most common unit system, so only "g" is formed as a gram display unit whose shape is set to g in advance as indicated by reference numeral 3 '. ing.

Next, reference numeral 4 is a setting item display section for displaying setting items when various settings are made on the electronic scale. In the display section, “AUTO” of 4a indicates the setting of the operation of the automation mechanism such as the automatic calibration of the electronic scale, “CAL” of 4b indicates the setting of the calibration, and “ACAI” of 4c indicates the setting of the number measurement. The measurement accuracy improvement setting, 4d “NET”, indicates the gross weight display setting of the weighing object, and 4e “ZERO” indicates the zero point setting. Since each display of the setting item display section 4 can be visually recognized even when the display is turned off, the functions possessed by the electronic scale can be confirmed at a glance by viewing the entire display.

Next, reference numeral 5 indicates an environment setting display portion, which is composed of a maximum of five star-shaped marks in the illustrated configuration. For example, in a precise weight measuring device such as an electromagnetic balance type electronic balance, vibration in the environment where the device is placed, especially in the place where the electronic balance is placed, greatly affects the measurement accuracy of the device, and there are relatively many vibrations. The measured data is not stable in places. In such a case, change the filter setting of the measurement data selection of the electronic scale so that it outputs a stable measured value.On the contrary, if there is no vibration etc. and the environment is good, the measured value will be faster. The average of the filter is changed so as to output. The environment setting display unit 5 is arranged to display a change in the sensitivity of the electronic scale corresponding to such an arrangement environment of the electronic scale. For example, when the star-shaped mark on the environment setting display unit 5 decreases, the sensitivity of the electronic scale is improved, and when it is increased, the sensitivity is decreased.

Reference numeral 6 indicates a comparator function display section. It should be noted that the alternate long and short dash line in the figure shows the range of the comparator function display portion, and the alternate long and short dash line is not displayed on the display body 1. The comparator function display section 6 is composed of symbols "+", "OK", and "-" in order from the top. For example, only "OK" lights up in blue or green like the main display section 2, and " "+" And "-" are configured to light up in the same color as the analog display section described later. The comparator function display portion 6 is a portion for displaying whether or not the weight of the measuring object is outside the allowable value, as described later.

Reference numeral 7 denotes an analog display unit that graphically displays the outline of the measured weight, and is configured by arranging a large number of parallel-line fluorescent units in series and forming a substantially crescent-shaped structure as a whole. There is. The analog display section 7 is lit in a color different from that of the main display section 2, for example, orange, so that the operator of the electronic scale can easily recognize it.

The display unit 1 shown in the figure is configured by arranging the display units in a horizontally long panel as described above. In addition, reference numeral 8 is a clock mode display mark, 9 is a weight placement state or a display prompting this placement, and 10 is a mark indicating a battery power shortage state. In addition, 11 is a granular material or the like, and the granular material is sequentially dropped into the weighing pan using a vibration feeder or the like, and the measurement target is placed on the weighing pan in time series. It is a so-called mark that lights up when measuring. Further, 12 "A NIMAL" indicates a measurement mode in the case where the object to be weighed is a living thing such as a rat and cannot be placed stationary on the weighing dish. Reference numeral 13 denotes a percent display unit that lights up when the display on the main display unit 2 is a percentage display. Further, reference numeral 14 is a stability display mark which is displayed when the electronic scale is stable.

Next, the operation (display) state of the display body will be described using a specific example.

When the electronic scale is first used in the weight measurement mode, the weight measurement key (not shown) is pressed. In this case, none of the displays on the setting item display section 4 light up unless special setting such as wind pulling is performed. Further, in the main display section 2, only the display section at the right end lights up the display of "0". In this state, when the load of the weighing object is applied, a numerical value is displayed on the display, but normally, a stable numerical value is not displayed for a few seconds. On the other hand, at the same time as the placement of the weighing object, the analog display section 7 lights up in orange, for example, and the parallel lines forming the analog section 7 light up sequentially from the bottom according to the weight of the weighing object. The amount of the parallel lines that illuminate corresponds to the maximum weight of the electronic scale, and as shown in FIG. When all lights up, the weight of the weighed item rarely matches the maximum weight of the electronic scale, and in many cases it becomes overloaded and measurement becomes impossible, so remove the weighed item when all of them light up. Is desirable.

FIG. 2 shows a lighting state of the analog display section 7. (A) shows that the weight of the weighed item is about 1/4 of the maximum weight of the electronic scale, and (B) shows that the weight of the weighed item is about 3/4 of the maximum weight of the electronic scale. Shows. Since the analog display section 7 is displayed almost at the same time when the weighing object is placed on the weighing dish, the operator can use the weighing object as a standard of the weight of the weighing object.

When the display unit system of the measured weight is displayed other than the gram display, the desired unit is selected by key operation. The selected unit is displayed on the unit display section, and at the same time as the display of this unit, the gram display 3'is turned off. 5 (A) and 5 (B) show display examples of units in the unit display section, where (A) is "Lb" or bond and (B) is "OZ" or ounce. Indicates.

The operation of the comparator function display unit 6 is as follows. Here, the comparator function is a function to detect whether or not the weight of the weighing object is within a permissible value by comparing it with a preset weight, and for example, it is possible to measure a large number of samples packed in equal amounts. This is convenient when checking whether or not the weight is a predetermined weight. When this function is set, for example, "+", "OK", and "-" composing the comparator function display section 6 blink for a certain period of time to notify the setting.

In the comparator function mode, “+” is lit up when the weight of the weighing object is larger than the set value, and conversely, “−” is lit when it is small. For example, if the weight of the item to be weighed is greater than the set value, and if the measured weight is greater than the set value, “+” and “OK” should light up and clear the standard. Let me know. If it matches the set value, only "OK" lights up. Further, when the value is less than the set value, only "-" lights up, indicating that the standard is not cleared.

When the above display is performed, as described above, “OK” is lit in the same color as the main display part 2 such as blue, and “+” and “−” are lit in the same orange color as the analog display part 7. Then, the combination of “OK”, “+”, and “−” can be clearly recognized.

When an allowable value of +-is set with respect to the set value, if the measured value is larger than the set value and is within the allowed value, "+" and "OK" are lit and the excess weight is displayed. If exceeds the allowable value, only "+" lights. Similarly, if the measured value is less than the set value and within the allowable value, "-" and "OK" are lit, and if the underweight is over the allowable value, only "-" is lit. .. It is also possible to display the actual weight on the main display unit 2 adjacent to the display of the comparator function.

Next, the display state at the time of various settings will be described.

For example, when setting the calibration, the electronic scale is set to the calibration mode by key operation. At the time of this setting, "CAL" of reference numeral 4b lights up on the setting item display portion 4 to display the setting item. Next, when the electronic scale actually enters the calibration operation, the "CAL" display on the setting item display section 4 is turned off, and instead the "CAL" is displayed on the main display section 2 as shown in FIG. When the calibration operation ends, this "CAL" display also goes out. If calibration is not possible due to external disturbances, etc., “CAL no” is displayed as shown in FIG. 3 (B) to indicate that fact.

Next, when the internal check of the electronic scale is performed and the internal mechanism is unstable due to disturbance or the like, an error message is displayed as shown in FIG. 4 (A), or the power cord is erroneously displayed. When the power is turned off and then turned on again due to a power failure or a power failure, that effect is displayed as "P-FAIL" as shown in Fig. 7B.

When the electronic scale is set to correspond to its layout environment, by setting this electronic scale to the environment setting mode, all the star-shaped marks in the front part of the environment setting display section 5 blink, and the predetermined scale is displayed. When the setting is completed, only the number of star marks corresponding to the setting will light up, and the others will go out. It should be noted that the environment setting display unit 5 is kept lit in the set state and displays the set state as long as the electronic scale is in use.

In the case of other clock display, the clock mode display 8 is turned on, and the time is displayed on the main display unit 2 as “08:16”.
