When the gear 15 is turned, the upper and lower small gears 23 to 25 and 28 to 30, which are in mesh with each other, rotate. Then, the display band 33 is sent in the desired direction, and the desired numbers can be selectively displayed on the windows 5-7.

By the way, as mentioned above, the adjacent large gear 13
-15 have small gears 23-25 and 28, respectively.
~30 are in mesh, so a certain large gear 13~1
Even when one of the gears 5 is rotated, the adjacent large gears are in mesh with the small gears, so a large frictional force acts between the gears, and on top of that, each spring 19, 27, 32 Since the adjacent gear groups are pressed, the gears adjacent to the rotated large gear will not rotate due to the pressing force. Once the large gear has been rotated, the spring will hold it in a stopped state once you release your hand.

That is, no deviation occurs between adjacent display bands 33.

In this way, any price can be displayed.

Incidentally, in the above embodiment, the price can be set freely, but it is not possible to distinguish between the price for one fish and the price for one bag.

An embodiment that improves these points will be described below.

Figures 10 to 12 are for explaining other embodiments of the present invention, and in each figure, the same or corresponding parts as in Figures 1 to 9 are designated by the same reference numerals, and their explanations will be omitted. .

In this embodiment, the overall size is slightly larger, and the windows 5 to 7 for displaying prices are provided on the lower right side of the front cover 2.

A measurement display window 34 is formed on the left side.

In this embodiment, this display window 34 is also one level lower and is formed in a quadrilateral shape.
Part 4 is also transparent.

On the other hand, the shafts 17, 21, 22 are also longer, and the 11th
As shown in the drawings and FIG. 12, another large gear 35 is rotatably supported at a position corresponding to the display window 34. This large gear 35 has the same shape as the other large gears 13 to 15, and has a cylinder 36 that fits into the shaft 17.

However, the mounting direction of the large gear 35 is opposite to that of the other large gears 13 to 15, and the cylinder 36 faces the bearing portion 20 side.

Then, between the large gears 13 and 35, the shaft 1
A spring 37 is elastically loaded in a state where the spring 37 is fitted into the spring 7.

Incidentally, small gears 39 and 40 each having a cylindrical shape are attached to the upper and lower shafts 21 and 22 in the same direction as the large gear 35, and mesh with the large gear 35, respectively.

A weight display band 38 is wound between the cylinders of these small gears 39 and 40 (not shown). In this weight display band 38, weights such as ``1 fish'', ``1 bag'', and ``1 pair'' are printed and displayed at a constant pitch in different colors.

If such a structure is adopted, the respective large gears 35, 13, 14, 15 and small gears 39, 4
0, 23, 24, 25, 28, 29, and 30 are pressed in a certain direction by a spring 37, so that the respective display bands 33 and 38 remain in position, and by turning the large gear 35, the quantity can be displayed. You can choose freely.

As is clear from the above description, according to the present invention, a plurality of display windows are formed on the front cover of the display casing, which is formed by combining a front cover and a back cover with a rearward protrusion.
