Learning ruler and print cutting method

Abstract

To solve the problem that there have been rulers in various shapes and structures in the past, but none of them count the number of characters or serve as a substitute for a flashcard.SOLUTION: Provided is a learning ruler including a ruler 2 having a stopper hole and a cutout portion, a ruler 3, a ruler 4, and a film 5 for memorization having a stopper hole, the stopper hole being fastened by a fastener 1, and the ruler 2, the ruler 3, the ruler 4, and the film 5 for memorization being pivotally supported at one point around the fastener. This allows the printout to be easily aligned to a line slightly inside the notebook while maintaining the storage capacity to be stored in a pencil case, and also allows the frame of the answer column to be easily created for questions with a specified number of characters, making it possible to study efficiently. It also allows the length of long objects to be measured and lines to be drawn. Furthermore, since the memorization sheet is fixed rotatably by the ruler and the fastener, its location will not become unknown.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention relates to a ruler that integrates various functions useful for learning. [Background technology]

[0002] There are cutters that cut printed materials to the desired size, which consist of a base with frame lines drawn for vertical and horizontal sizes such as A and B, a narrow paper holder that can move approximately vertically relative to the base, and a push-cutting blade that is pivotally supported on the base, or a blade that protrudes downward and is restricted in its movement along the longitudinal direction of the narrow paper holder. The cutter cuts printed materials to be cut to the desired size by passing the printed material to be cut through the gap between the base and the paper holder, aligning it to the frame lines of the desired size, and then pressing and fixing the printed material with the paper holder and cutting it.

[0003] In addition, there are work papers and notebooks with grids that allow you to count the number of characters, and there are also rulers that make counting easy by marking the top, bottom, left, and right with numbers.

[0004] There are 30cm rulers and foldable rulers that can be used to measure long objects without using a paper cutter or a gridded notebook. There are also multi-purpose rulers that have a protractor function in the center, allowing you to measure angles as well as length.

[0005] On the other hand, flashcards exist as a memorization tool for study. They are available in various sizes to fit the size of the textbook or reference book in question, and can be used to cover printed or handwritten parts of the same color with red or green sheets. By holding the flashcard over the target part and then removing it, you can easily check your own memorization status. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Jitsuzen Showa 60-026897 [Patent Document 2] Actual total number 4-113997 [Patent Document 3] Patent Publication No. 2012-158040 Summary of the Invention [Problem to be solved by the invention]

[0007] When you paste a B5-sized printout distributed at school or cram school into a B5-sized notebook to create a new notebook, the printout will go over the edge. This means that in order to cut to the desired size using a paper cutter, you need to shift the printout toward the cutting edge rather than the border. This can be solved by drawing a new border, but since there are many printouts to cut, it is possible to get the borders wrong and end up cutting twice. Moreover, paper cutters are large in order to accommodate the size of the printed matter, and are somewhat heavy, making them difficult to transport.

[0008] With graph paper and other paper with grids, the divisions of the grids are clear, and it is easy to check the number of characters by looking at the scales on the top, bottom, left, right, and edges. However, since the scales are only on the edges, they are completely useless if you are away from the edges.

[0009] A 30cm ruler sticks out of a backpack, so there is a risk of injury from the sharp corners. For this reason, to ensure safety, it is necessary to carry it in a storage bag. Folding rulers are easy to store and carry, but they have fewer functions.

[0010] If the flashcards are larger than textbooks or reference books, they will bend and become uneven when carried in a backpack or bag, and will turn white, making them difficult to see. On the other hand, if the flashcards are small, these problems will not occur, but the answers will be visible if you cannot hide the parts you want to hide, or you will not know where you put the flashcard.

[0011] In order to solve the problems described above, the inventions and devices in Patent Documents 1 to 3 have various shapes and structures, but none of them are rulers that count the number of characters or serve as a substitute for a flashcard. [Means for solving the problem]

[0012] In order to solve the above problem, the invention of claim 1 comprises a ruler 2 having stop holes 2 and cut-out portions 2, a ruler 3 having stop holes 3 and cut-out portions 3, a ruler 4 having stop holes 4 and cut-out portions 4, and a flashcard film 5 having stop holes 5, wherein the stop holes 2, the stop holes 3, the stop holes 4 and the stop holes 5 are fastened with fasteners, and the ruler 2, the ruler 3, the ruler 4 and the flashcard film 5 are supported by a single axis around the fastener so as to be freely rotatable. Effect of the Invention

[0013] According to the present invention, while maintaining the storage capacity of being able to be stored in a pencil case, etc., the distributed printout can be easily aligned to a line slightly inside the notebook, and the printout can be neatly pasted without going beyond the notebook. In addition, for questions with a specified number of characters, the answer column can be easily framed, making it possible to study efficiently. It is also possible to measure the length of long objects and draw lines. Furthermore, since the flashcard is fixed rotatably with a ruler and a fastener, it will not become unknown where it is.

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. The following embodiment is an example for explaining the present invention, and is not intended to limit the present invention to the embodiment. Furthermore, the present invention can be modified in various ways without departing from the gist of the invention. Furthermore, the same components in each drawing are denoted by the same reference numerals as much as possible, and duplicated explanations are omitted.

[0016] <Embodiment> Fig. 1 shows an overall view of a multi-functional ruler according to an embodiment of the present invention, Fig. 2 shows the front side of an exploded view of a multi-functional ruler according to an embodiment of the present invention, and Fig. 3 shows the back side of an exploded view of a multi-functional ruler according to an embodiment of the present invention. The fastening holes 21, 31, 41, and 51 are fastened with fasteners 1, and rectangular rulers 2, 3, and 4 of different lengths and a flashcard film 5 are supported rotatably at one point. The three types of rulers have cutouts 22, 32, and 42 of different lengths formed in the center of the short side.

[0017] As an example, we will show a combination of ruler 2 and ruler 3 for pasting on a B5 size notebook, and ruler 3 and ruler 4 for pasting on a B6 size notebook. The width W of ruler 2, ruler 3, ruler 4, and flashcard film 5 is preferably the same size, but may differ within a few millimeters. The width W is most preferably 30 mm, the same as that of a commonly used ruler, but no particular size is specified. The flashcard film 5 is preferably made of a red translucent material used for study purposes.

[0018] In addition, the length H2 of ruler 2, the length H3 of ruler 3, the length H4 of ruler 4, and the length H5 of flashcard film 5 are not specifically defined, but taking into consideration portability, etc., it is preferable that H2 be approximately 260 mm, H3 be approximately 190 mm, H4 be approximately 120 mm, and H5 be approximately 150 mm, respectively.

[0019] In order to facilitate counting the number of characters as shown in FIG. 2, character count guides 201 to 204, 301 to 304, 311 to 313, 401 and 402 may be marked on the front side of the ruler, and scales 23, 33 and 43 may be marked on the back side as shown in FIG. 3.

[0020] As shown in the figure, ruler 2, ruler 3 and ruler 4 are respectively configured with cutouts 22, 32 and 42 of equal width but different vertical dimensions. The cutouts 22, 32 and 42 may be aligned with character count guides 201 to 204, 301 to 304, 311 to 313, 401 and 402, and the vertical dimensions may correspond to the length of a desired number of characters.

[0021] By drawing lines along the cutouts 22, 32, and 42 and marking the marks on the character count guide, an answer column with a specified number of characters can be easily created. Here, the cutouts 22, 32, and 42 are continuous in a rectangular shape, but it goes without saying that the same effect can be achieved by making each character independent, like a square window frame.

[0022] <Example 1> Next, the print cutting method will be explained using Figures 4 and 5. Figures 4 and 5 show how to use the ruler for a B5 print 6. As shown in Figure 4, open rulers 2 and 3 into an L shape, align the rotation axis with the lower left corner of print 6, and set the ruler so that the center of the short side is at the edge of print 6.

[0023] The cut point can be clearly indicated by drawing a line along the inside of the L shape formed by rulers 2 and 3. Furthermore, as shown in Figure 5, by rotating the print 180 degrees while maintaining this L shape, aligning the stopper with the upper right corner of print 6, and drawing a line along the inside of the inverted L shape, the cut point can be clearly indicated.

[0024] <Example 2> Figures 6 and 7 show how to use rulers for a B6 print 7. Using rulers 3 and 4, you can clearly indicate the cutting points in the same way as for a B5 print. Here, we have focused on B5 and B6 prints, but it goes without saying that you can match them to any desired print size, and you can also combine three or more types to achieve the same effect.

[0025] <Example 3> Fig. 8 is an explanatory diagram for creating an answer column for a question with a specified number of characters. As mentioned above, the three types of rulers 2, 3, and 4 have cutouts 22, 32, and 42, and character number guides 201 to 204, 301 to 304, 311 to 313, 401, and 402 are written on the front.

[0026] As shown in the figure, when the words "This invention makes learning proceed smoothly" are superimposed on the cutout 22, it is easy to tell that the number of characters is 15 from the character count guides 201 to 204. As an example, the cutouts 22, 32, and 42 and the character count guides 201 to 204, 301 to 304, 311 to 313, 401 and 402 on the front may be prepared based on characters written on a notebook with a 10 mm grid that is frequently used for studying, or another size may be used as the base.

[0027] <Example 4> Figure 9 shows how to measure the length of a long object. When ruler 3 is rotated 180 degrees relative to ruler 2, the markings on the back of the ruler become continuous, and it is possible to transform it into a 42 cm ruler, for example.

[0028] <Example 5> Figure 10 shows how to use the flashcard film 5. The three types of rulers are in the same position, and only the flashcard film 5 is rotated 90 degrees. By pressing the long edge of the ruler against the edge of the notebook and moving it up and down, the flashcard film 5 can be moved along the horizontal lines, improving usability. For vertical writing, simply rotate the whole ruler 90 degrees to align it with the top edge of the notebook.

[0029] Here, the width of the flashcard film in the short direction is set to be the same as that of a ruler, but if the film is made of a material that is less likely to break, the flashcard film can be set to be wider than the width of a ruler.

[0030] Here, for simplicity, the three types of rulers and the flashcard film 5 are fixed rotatably with a fastener 1. Using known technology such as screws makes it easier to attach and detach. Alternatively, the rotating part can be made in an inverted V shape, and for example, a magnet can be added to the inverted V-shaped part of the flashcard film 5 and the inverted V-shaped parts of the other rulers can be made of iron, making it easier to attach and detach.

[0031] Furthermore, in addition to the functions described here, it goes without saying that it may also be equipped with functions such as a paper knife function, a protractor function, and a light shielding plate function, which are well known in the art. [Explanation of symbols]
