Description

[Detailed Description of the Invention] The present invention relates to a scale suitable for measuring the net weight after subtracting the weight of the tare bag.

Previously, for example, Utility Model Publication No. 45-27269,
Japanese Patent No. 52-134364 proposes a scale in which a pointer is rotatably attached to a fixed scale plate, and a rotary scale plate is pivoted to a cover of the fixed scale plate. However, in such conventional scales, the rotary scale plate is pivoted to the cover of the fixed scale plate and is not directly connected to the axis of the fixed scale plate, so when assembling the scale, the axis of the fixed scale plate and the axis of the rotary scale plate It is difficult to align the scales, and the pointer on the fixed scale plate does not accurately point to the scale on the rotary scale plate, resulting in poor measurement accuracy.

In view of these shortcomings, the inventor of the present invention has succeeded in solving them as a result of intensive research and has completed the present invention.

The present invention will be described in detail below with reference to the drawings.

In the drawing, 1 is the scale body. The scale body 1 is not particularly limited, and can be used for commercial purposes such as weighing products at a store, or for cooking at home. Note that 11 is a saucer and 12 is a cover.

Reference numeral 2 denotes a fixed scale plate, which is attached to the front of the scale body 1. The fixed scale plate 2 has a circular outer shape, and allows a rotary scale plate 4 or a transparent disc 6, which will be described later, to rotate smoothly.

3 is a guideline. The pointer 3 is attached to a rotary shaft 31 that projects from the scale body 1 to the center of the fixed scale plate 2, and is rotated by a predetermined angle by the load applied to the scale body 1 to indicate a predetermined scale position on the fixed scale plate 2. It is done like this.

4 is a rotary scale plate. The rotary scale plate 4 is made of a transparent plate, and has scales 41 corresponding to the scales 21 of the fixed scale plate 2. Further, the rotary scale plate 4 is rotatably attached to the fixed scale plate 2 so that its axis coincides with the axis of the fixed scale plate. For example, in the case of FIG. 1, the outer periphery of the rotating scale plate 4 in the form of a transparent disc, which has approximately the same diameter as the fixed scale plate 2, is rotatably attached to the fixed scale plate 2. A side wall 42 is formed extending toward the fixed scale plate 2, and an annular groove 43 is carved in the inner wall of the side wall 42. The outer peripheral edge of the fixed scale plate 2 is fitted into the annular groove 43, and a rotation scale is formed. Knob 5 provided in the center of plate 4
By turning, the rotary scale plate 4 changes to the fixed scale plate 2.
It is configured to rotate on the same axis along the outer periphery of the. In addition, in the example shown in FIG.
1 is rotatably fitted into the annular groove 62 of the transparent disc 6, and the shaft 51 of the knob 5 provided on the transparent disc 6
The rotary scale plate 4 is attached concentrically to the shaft 51, and by turning the knob 5, the rotary scale plate 4 is aligned coaxially with the fixed scale plate 2 via the transparent disk 6. It is designed to rotate on a line.

Next, we will describe how to use the scale of this invention.

First, a tare bag, container, etc. is placed on the tray 11 of the scale body 1. Next, using the knob 5, align the O point of the scale 42 of the rotary scale plate 4 with the pointer 3 indicating the weight of the tare. In this state, while looking at the scale 42 of the rotary scale plate 4, it is sufficient to put the article to be tared into the tare.

As detailed above, in the scale of the present invention, the fixed scale plate and the rotary scale plate are on the same axis, either directly or through a transparent plate, so the pointer can accurately point to the scale of the rotary scale plate, and the scale of the rotary scale plate Improves measurement accuracy.
