Abstract

PURPOSE:To make not only the center of the receiving pan of an electronic balance, but also the dimension of an article placed on the receiving pan confirmable at a glance by forming marks which become successively larger as going toward the periphery of the receiving pan from the center of the pan on the pan. CONSTITUTION:In a load cell balance 1, a rectangular receiving pan 2 is provided on the upper surface of a main body housing 3 and a display 4 is provided on the front surface of the housing 3. Rectangular marks 5 having different sizes are formed on the pan 2 so that the sizes of the marks 5 can successively become larger as going toward the periphery of the pan 2 from the center of the pan 2. The marks 5 are classified by color in corresponding to the basic sizes of articles to be weighed. Semispheric projections 7 are formed on the surface of the pan 2 near the four corners of the pan 2 so as to separate objects to be weighed front the surface of the pan 2 and a level 8 is provided in the from edge section of the pan 2. The weight of an object to be weighed is measured from the quantity of distortion of the load cell caused by the object and displayed on the display 4. Since the center of the pan 2 can be confirmed at a glance, the occurrence of weighing errors can be prevented and, in addition, the size of the object can be recognized roughly from the successively expanding marks 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic balance in which a saucer is connected to a movable portion of a load cell in which a fixed portion is connected to a main body housing.

[0002]

2. Description of the Related Art At present, a load cell scale is put into practical use as an electronic scale for calculating the weight of an article as electrical data. This load cell scale is one in which a strain gauge connected in a bridge is provided in the strain-flexing portion of the load cell, the fixed end of the load cell is connected to the main body housing, and the saucer is connected to the movable end. Therefore, such a load cell scale is designed so that the strain amount generated in the load cell due to the weight of the articles loaded on the tray is electrically measured by a strain gauge and measured, and this weight is displayed on the display unit. For example, it is also used for weighing mail and parcels.

[0003]

The load cell balance as described above can measure the weight of the article placed on the tray.

However, in the load cell scale as described above, when an article is placed at a position away from the center of the tray, an unnecessary moment acts on the load cell and an error may occur in the measured value. Therefore, when the weight of the article is precisely measured by a load cell balance, it is desirable to place the article in the center of the saucer, but in reality, the article is often placed on the outer peripheral portion of the saucer. is there.

[0005] In post offices, the weight of postal items, parcels, etc. is measured by a load cell balance in order to determine the delivery fee. Instead, it is often decided in consideration of dimensions. For this reason, the weight of mail, parcels, etc. is measured with a load cell balance, and then the size thereof is measured with a measure or the like, which complicates the work.

[0006]

In an electronic balance in which a pan on which an article is placed is provided on an upper surface of a main body housing, and the pan is connected to a weight sensor provided inside the main body housing, the pan of the pan is Marks were formed on the surface so as to gradually expand from the center toward the periphery.

[0007]

[Function] By the mark formed on the surface of the saucer, which gradually expands from the center toward the periphery, the center of the saucer can be checked at a glance, and the size of the article placed on the saucer can be checked at a glance by the mark It can be so.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As an embodiment of the electronic scale of the present invention, a load cell scale for weighing mail by a load cell will be described below with reference to the drawings. First, the load cell scale 1 which is this electronic scale
Is provided with a saucer 2 on an upper surface of a main body housing 3, and the saucer 2 is connected to a movable end of a load cell (not shown) having a fixed end connected to the main body housing 3. A display 4 is provided on the front surface of the main body housing 3, and the load cell is connected to the display 4 via a processing circuit (not shown).

The receiving tray 2 is formed in a substantially rectangular shape, and rectangular marks 5 having different sizes are formed on the surface thereof from the center toward the periphery. here,
The marks 5 are color-coded into red, blue, yellow, etc. corresponding to the standard dimensions of a mail item (not shown) that is an item to be weighed. For example, the innermost mark 5 is the size of a regular mail item, The second mark 5 is the size of the non-standard size mail. The mark 5 is formed by a single sticker 6 which is attached to the surface of the tray 2 in a replaceable manner.

Further, in this load cell balance 1, hemispherical projections 7 are provided near the four corners of the surface of the tray 2 to release the mail items (not shown) to be placed from the surface of the tray 2.
And a level 8 is provided at the front edge of the surface of the tray 2.

In this configuration, the load cell balance 1 is formed here for the purpose of weighing mail items, and when a mail item is placed on the tray 2, the weight is measured by the amount of strain generated in the load cell. Weight display 4
It is supposed to be displayed.

The load cell scale 1 has a mark 5
Since the center of the tray 2 can be confirmed at a glance, the postal matter is naturally placed on the center of the tray 2, and the weighing error caused by placing the article on the peripheral portion of the tray 2 is prevented. It is like this.

Further, in the load cell balance 1, since the outline of the size of the postal matter placed on the tray 2 can be confirmed at a glance by the mark 5, the weight of the postal matter can be measured and the size can be confirmed to simplify the delivery charge. And you can make quick decisions. Since the size of the postal matter that determines the delivery fee is regulated in stages, the mark 5 is formed corresponding to this reference dimension, and the mark 5 is color-coded according to the delivery fee. The delivery fee can be confirmed easily. In addition, since the mark 5 is formed by one sticker 6 here, even when the mark 5 is soiled or when the standard size of the postal matter is revised due to revision of the law, etc., This can be easily dealt with by replacing the sticker 6.

Further, the load cell balance 1 exemplified as the electronic scale in the present embodiment has exemplified the postal matter as an article for measuring the weight by the mark 5 of the tray 2 and confirming the outline of the dimension, but the electronic scale of the present invention. The use of is not limited to the above embodiment, and can be used for measuring the weight and confirming the dimensions of various articles such as parcels and trays of self-service stores.

In the load cell balance 1 of the present embodiment, the rectangular mark 5 is formed on the rectangular saucer 2, but the present invention is not limited to the above embodiment and can be applied to its application. It is also possible to form a square or circular mark on a rectangular saucer. That is, the shape of the saucer is not directly related to the present invention, and the shape of the mark may be formed so as to correspond to the shape of the article to be confirmed.

[0016]

As described above, the present invention provides an electronic scale in which the tray on which the article is placed is provided on the upper surface of the main body housing, and the tray is connected to the weight sensor provided inside the main body housing. , By forming a mark on the surface of the saucer that sequentially expands from the center to the periphery, the center of the saucer can be confirmed at a glance by the mark,
Articles will be naturally placed in the center of this saucer,
Weighing is easy to perform accurately, and the size of the goods placed on the pan can be checked at a glance with a mark. It is also possible to determine simply and quickly.
