Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support structure for a pinion shaft of an integration counter.

FIG. 1 is a perspective view for explaining a conventional integration counter. Numeral wheels 1, 2, 3, and 4 are used to display integrated values, and gears 5 and 6 are on the numeric wheels 2 to 4, respectively. and 7
are integrally provided.

8 is a number axle 9 that rotatably supports number wheels 1 to 4;
10 and 11 are pinions that mesh with the gears 5 to 7, respectively; 12 is a pinion shaft that rotatably supports the pinions 9 to 11; and 13 is the both ends of the numerical axle 8 and the pinion shaft 12.
The support frame 13 has a hole 14 for supporting the numerical axle 8 and a groove 15 for slidably supporting the pinion shaft 12.

Reference numeral 16 denotes a spring mounted between the numerical axle 8 and the pinion shaft 12, and the tensile force of the spring 16 causes the gears 5 to 7 and the pinions 9 to 11 to be pressed and engaged, respectively.

This totalizing counter counts numbers wheels 1 to 4 by counting means (not shown), and also applies rotational force to each number wheel 1 to 4 using a zero return means (not shown). In this way, the pinion shaft 12 is slid in the direction of the arrow A along the groove 15 against the tensile force of the spring 16, and the gears 5 to 7 and the pinions 9 to 11 are disengaged from each other. Return each number wheel 1 to 4 to zero, return each number wheel 1 to 4,
Or move forward. However, this conventional integration counter has disadvantages such as the use of the spring 16, which increases the number of parts, increases the price of the product, and increases the volume of the integration counter. The present invention has been made to eliminate the drawbacks of the conventional integration counter as described above, and will be described in detail below with reference to FIG. 2.

In FIG. 2, parts having the same functions as those in FIG. 1 are given the same reference numerals, and detailed explanation thereof will be omitted. Now, in FIG. 2, reference numeral 17 is a spring formed by cutting out a part of the support frame 13, and the pinion shaft 12 is supported on the free end of this spring 17. This spring 17 has the same role as the spring 16 shown in FIG.
The restoring force of the spring 17 presses the pinions 9 to 11 against the gears 5 to 7 and brings them into contact with each other. When returning to zero, the pinion shaft 12 moves in the direction of arrow B against the restoring force of the spring 17, and the gears 5 to 7 and pinions 9 to 11 are disengaged from each other. As is clear from the above description, according to the present invention, the number of parts can be reduced, so the price of the product can be reduced and the volume of the product can be reduced.
