[Problems to be solved by the device]

 In the case of the above-mentioned counter, it is very convenient to place balls while counting, or to physically check the number as a number of gatherings, but it is a decimal decimal place where 10 and 1 are exchanged. Not suitable for learning number systems. Also, abacus is a very good calculator for learning the scale, but abacus using 5 beads and 1 beads in combination is quite difficult for young children.

The technical problem of the present invention is to realize a counter which enables children of infancy to easily understand not only concrete numbers but also abstract numbers accompanied by scales, and to enjoy learning.

[0007]

[Means for Solving the Problems]

 According to a first aspect of the present invention, as illustrated in FIG. 4, each of the shafts 2 fixed in parallel to the quadrangular frame 1 is provided on each of ten balls 3 in a comb-like shape. A counter that can be used as a hundred-counter counter by providing at least 10 rows of comb-shaped shafts 2, and that can be used as a scale counter by displaying a scale on the surface of the horizontal frame 1a. Is. As shown in the figure, the scale display 4 shows the letters indicating 1, 10, 12, 100, 100, and bun in order from the right side. Characters representing places may be Chinese or arithmetical numbers.

According to a second aspect of the present invention, as illustrated in FIG. 1 or 2, at least one of the horizontal frame 1a and the vertical frame 1b is arranged so that the balls 3 do not protrude from both front and back surfaces. In the counter, the thickness of the frame is made larger than the diameter of the ball 3 of the counter, and the scale display 4 is provided on either side of the horizontal frame 1a. In the frame 1, a portion provided parallel to the shaft 2 is called a vertical frame 1b, and a portion provided at a right angle to the shaft 2 and to which the shaft 2 is attached is called a horizontal frame 1a. The shaft 2 is preferably attached at the center of the thickness of the frame 1.

A third aspect of the present invention is a counter, as shown in FIG. 1, in which two sets of scale indications 4 are repeatedly provided on the surface of the horizontal frame 1a. From the right side, the scale display 4 is composed of five characters, 1, 10, 12, haku, sen, and bun, repeated twice in the right side scale display part and the left side scale display part. The place name may use Chinese or arithmetic numbers.

According to a fourth aspect of the present invention, as illustrated in FIG. 1 (1), among the respective balls 3 supported by the respective shafts 2, the upper 5 pieces 3a and the lower 5 pieces 3b are different. The counters are colored, and the upper five 3a are counters of different colors. Therefore, the balls with the same number have the same color scheme.

[0011]

[Action]

 According to claim 1, having both the functions of a hundred-counter counter and a scale counter, one counter can be used to learn a specific number and to calculate an abstract number or calculation based on the scale. It can be used for both learning and is economical because it is not necessary to prepare two counters for each purpose.

When the thickness of the frame 1 is made larger than the diameter of the ball 3 of the counter and the horizontal frame 1a is provided with a scale display 4 on either side of the front and back sides, the front and back sides can be arranged. Both sides can be used, one side can be used as a hundred-counter counter, and the other side can be used as a scale counter. By inverting both sides, it is easy and quick to use two counters. Functions can be used.

When the counter 4 is provided with two sets of scale indications 4 on the surface of the horizontal frame 1a repeatedly, as shown in FIG. 3, as shown in FIG. Can be displayed. Therefore, it is easy to understand the difference when judging by comparing the difference between the two numbers. Also, since the numbers can be displayed on the right side scale display part and the left side scale display part, respectively, and these two displayed numbers can be used for calculation as they are, the movement of the ball 3 can be visually confirmed, It will be easier to understand the mechanism of calculation by the grade taking.

According to a fourth aspect, in each of the balls 3 supported by the respective shafts 2, the upper 5 pieces 3a and the lower 5 pieces 3b have different colors, and the upper 5 pieces further. If 3a is a counter having a different color for each position, the numbers are easier to count by different colors, and since the respective positions have the same color, comparison is easy. You can also enjoy the colors by using colorful primary colors.

【Example】

 Next, a practical example of how the counter according to the present invention is implemented will be described. 1 is an embodiment of a counter according to the present invention, (1) is a plan view of the surface, and (2) is a vertical sectional view taken along line AA. FIG. 2 shows an example of the back surface of the counter according to the present invention.

In this counter, ten balls 3 are provided in a comb-like shape on each axis 2 fixed in parallel with a rectangular frame 1, and the comb-like axis 2 is 10 in number. There are rows. In addition, the thickness of the vertical frame 1b is made larger than the diameter of the ball 3 of the counter so that the balls 3 do not project from both the front and back surfaces of the vertical frame 1b of the rectangular frame 1, and the front and back sides of the horizontal frame 1a are also made. The thickness of the lateral frame 1a is set to be smaller than the diameter of the ball 3 of the counter so that the ball 3 projects from both sides. The thickness of the horizontal frame 1a may be the same as the thickness of the vertical frame 1b, as indicated by the dashed-dotted line in FIG. As the balls 3, plastic abacus balls are used.

A display 4 is provided on the surface of the horizontal frame 1a for scale. The scale display 4 is composed of two sets of letters from the right, in the order of 1, 10, 10, haku, sen, and bun, and is displayed on the surface of either one of the upper and lower horizontal frames 1a. In addition, the place name may use Chinese numerals or arithmetic numerals. Further, each of the balls 3 supported by the respective shafts 2 has the upper 5 pieces 3a classified into 5 types by each position, and the lower 5 pieces 3b are white. The counter configured in this way uses the front side with scale display as a scale counter and the back side without scale display as a hundred-ball counter.

The hundred-ball counter is a very effective device for learning the number of children in infancy, and it can be used to move the ball 3 with a finger so as to keep track of the number or count the number of sets. , It is widely used to interact with numbers in a fun way and to make the concept easy to understand.

In the counter according to the present invention, among the 10 balls 3 of each axis 2, the upper 5 pieces 3a and the lower 5 pieces 3b are colored in different colors, so that the division of 5 pieces is intuitive. It is easy to recognize the number, and the upper 3 balls 3a of each shaft 2 are color-coded for each position, so that the position can be easily recognized. In addition, because the colors are arranged in colorful primary colors, even children in early childhood can be familiar, interested, and have fun in learning numbers.

As described above, the conventional one-hundred coin counter is mostly used as a counter for recognizing a concrete concept of a number, and the principle of the decimal notation system and addition / subtraction Is not suitable for learning. The present invention, when used together as a scale counter, makes it possible to learn the mechanism and calculation of the decimal scale very effectively.

As shown in FIG. 3, since the scale display 4 is repeatedly displayed at two places on the left and right, in the case of addition, etc., the number to be added to the left scale display is set and added to the right scale display. The number can be set, and the calculation can be done while looking at both numbers. As a result, the number of mental calculations is reduced, and calculations can be performed while visually recognizing sufficiently, making it easier to understand.

For example, in the case of the calculation of 23 + 8, as shown in FIG. 3 (1), 2 is placed in the tens place and 3 is placed in the ones place in the left side scale display part, and the right side scale display part is displayed. Put 8 in the first place. Here, replacement is performed in order to change 10 of the first digit of the right scale display unit to 10. In other words, the two balls of the unit A on the left side of the scale display section are replaced with the two balls of the unit B on the right side of the scale display unit. By this replacement, the arrangement of the balls 3 becomes as shown in (2). Here, further, the ten balls in the C part of the first place in the right scale display part are replaced with the one ball in the D part of the tens place in the left scale display part. As a result of the calculation, as shown in (3), three balls at the tens place and one ball at the ones place remain on the left scale display part, and the answer becomes 31.

In this way, since the replacement of the number being calculated can be visually confirmed by the movement of the ball 3, there are less parts to be mentally calculated than when the abacus is used, and even a child in early childhood can understand the decimal number. It will be easier. Calculations such as subtraction may be similarly performed.

FIG. 4 shows a counter with a movable scale display plate according to the present invention. (1) shows the usage state as a scale counter, and (2) shows the usage state as a hundred-counter counter. (3) is a side view of the A portion. This counter is provided with ten balls 3 which are inserted in a comb-like shape on each axis fixed in parallel with a quadrangular frame 1, and ten rows of the comb-like axis 2 are provided. Each ball is fixed so as to protrude from the surface of the frame 1. The frame 1 is composed of a vertical frame 1b provided parallel to the axis and a horizontal axis 1a to which the axis 2 is attached and which is provided at a right angle to the axis 2. Is provided with a movable scale display plate 5.

This movable scale display plate 5 is provided with a plate 6 on the surface of which the scale is displayed, and rotary support fittings 7 at the left and right ends of the display plate 6, and the rotary support fitting 7 is a horizontal frame. It is fixed to both ends of 1a.

As shown in FIG. 4, this counter has a structure in which the scale display plate 6 is movable, and with the rotation support metal fittings 7 fixed to both ends of the horizontal frame 1a as a fulcrum, as shown in FIG. ), And the scale display plate 6 is set on the horizontal frame 1a. This allows the 100-ball counter to be used as a scale counter. The rotary scale display plate 5 may be attached to either or both of the upper and lower horizontal frames 1a. The operation is only required to rotate the rotary scale display plate 5, and a counter having both functions of a hundred-ball counter and a scale counter can be easily realized. Contrary to the above, the scale may be displayed on the horizontal frame 1a without displaying the scale on the display plate 6, or the scale display plate may be detachably provided on the horizontal frame 1a. .

Further, by attaching the movable scale indicator plate 5 to the conventional hundred-counter counter, the function of the scale counter can be provided easily and inexpensively, which is economical.
