Problems solved by technology

Sexagesimal has not been found in various address codes in the current digital equipment and communication fields.
[0011] However, the inventors have learned that although the existing decimal coded elements and the corresponding improved decimal coded elements can provide greater coding capacity, because the number of elements is ten times that of the existing decimal coded elements, resulting in its There are great difficulties in quick search, identification and learning, and it is not easy to promote
Simple printing of decimal elements on paper is inconvenient for long-term storage, takes up a large area when used, and is not convenient for comparative learning of decimal elements and decimal elements

Embodiment 1

[0080] like Figure 1-Figure 8 As shown in the figure, this embodiment provides a hundred-element learning slide rule, which includes a base body 1, and a plurality of mutually parallel slide grooves 12 are arranged in a row in the base body 1. As a decimal element, a plurality of sliding pieces can be independently extended and retracted along the chute 12 , so that different sliding pieces are exposed outside the base body 1 .

[0081] The slider has a decimal printing area 7 and a decimal printing area 8, and the marked number of decimal elements in different sliders is the same.

[0082] The surface of the base body 1 forms a marking surface, and the marking surface and the sliders together indicate the decimal elements, the marking surface and each slider are marked with 20 decimal elements, and the number of the sliders is four.

[0083] It can be understood that, in this embodiment, the number of buttons is also four, that is, the first button 3 , the second button 4 ,...

Embodiment 2

[0093] like Figure 9-Figure 12 As shown, a hundred-element learning slider is also provided. The difference between this embodiment and Embodiment 1 is that the slider includes two half-sliders, and the two half-sliders are spliced ​​to form a slider, and each half-slider is The end of the sliding piece is provided with a semi-convex piece, the two sliding pieces are respectively used to indicate the decimal element and the corresponding decimal element value, and the two semi-convex pieces are spliced ​​to form a convex piece; The width direction of the sheet is slid and positioned so that the buttons are respectively aligned with the two half-tabs used together, so that the two half-slides can be independently extended and retracted.

[0094] The number of the upper buckles 10 in each chute 12 is two, and one of the lower buckles 9 is respectively provided on each half-tab.

[0095] Specifically, the drawings in the description exemplarily show a schematic diagram of dispo...

Abstract

The disclosure relates to a slide rule for learning decimal elements, which includes a base body, in which a plurality of parallel chute is arranged in a row, and a sliding sheet is arranged in the chute, and the hundred element is marked on the sliding sheet, and a plurality of sliding slots are arranged in the chute. The sheets can independently expand and contract along the chute so that the different slides are exposed outside the base. The present disclosure facilitates the learning of decimal elements.

Description

technical field [0001] The present disclosure belongs to the technical field of learning teaching aids, and in particular relates to a hundred-element learning slide rule. Background technique [0002] The statements herein merely provide background related to the present disclosure and do not necessarily constitute prior art. [0003] Binary 0, 1 are represented by high level---1 and low level---0 in digital circuits, digital equipment, and computers. Easy to handle in computers and digital devices. Promote the development of binary coding and the progress of modern science and technology. [0004] Decimal counting was invented by the Hindus 1500 years ago and passed down by the Arabs to the 11th century. Various address codes are used the most, such as mobile phone numbers, which use the decimal addressing coding mode. Basic elements of decimal coding: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 every decimal one (full decimal one), the philosopher's explanation: people have ten fing...
