Description

Application of Article 30, Paragraph 2 of the Patent Act ・October 5th to October 8th, 2021 Seiran Tanaka disclosed an educational ruler and print cutting method at the Familiar Hints and Inventions Exhibition.

The present invention relates to a ruler that integrates various functions useful for learning.

Used as a cutter to cut printed matter to the desired size, it has a base with frame lines drawn for vertical and horizontal sizes such as A and B versions, and a narrow paper holder that can move approximately vertically relative to the base. There are some types that consist of a push-cutting blade rotatably supported on a base, or a downwardly protruding blade whose movement is restricted along the longitudinal direction of a narrow paper holding part. The cutting machine can cut the printed matter to a desired size by passing the printed matter to be cut through the gap between the table and the paper holding part, aligning it with the frame line of the desired size, holding down and fixing the printed matter with the paper holding part, and cutting.

Furthermore, there are work papers and notebooks that have grids that allow you to count the number of characters, and there are also rulers that make counting easier by marking numerical scales on the top, bottom, left and right sides.

There are 30cm rulers and foldable rulers that can be used to measure long objects without using a cutting machine or a notebook with squares. There are also multifunctional rulers that have the function of a protractor in the center of the ruler, allowing you to measure not only length but also angles.

On the other hand, memorization sheets existed as memorization tools for learning. Printed matter or handwritten parts of the same color can be hidden with red or green sheets of various dimensions depending on the size of the target textbook or reference book. By holding the memorization sheet over the target area and lifting it away, you can easily understand your memorization status.

If you paste the B5 size printouts handed out at schools or cram schools into B5 size notebooks and make new notes, the prints will stick out. Therefore, in order to cut the print to the desired size using a cutter, it is necessary to shift the print toward the cutting side from the frame line. This can be done by drawing a new frame line, but since a large number of prints are to be cut, you may end up choosing the wrong frame line and end up having to do it twice. Moreover, the cutter is large to accommodate the size of the target printed matter, and has a certain amount of weight, making it difficult to transport.

When using grid paper such as graph paper, the divisions between the grids are clear, and it is easy to check the number of characters by looking at the scales written on the top, bottom, left and right edges. However, since the scale is only on the edge, the scale is completely useless at a position away from the edge.

A 30cm ruler is carried so that it protrudes from a school bag, so there is a risk of injury due to the protrusions on the corners. Therefore, to ensure safety, it is necessary to take measures such as transporting the product in a storage bag. Folding rulers are easy to store and transport, but they have fewer functions.

If a memorization sheet that is larger than a textbook or reference book is carried in a school bag or bag, it will bend, become uneven, and turn white, making it difficult to read. On the other hand, if it is small, these problems do not occur, but the answer may be visible because the part you want to hide cannot be hidden, or the location of the hidden part may become unknown.

In order to solve the above problems, the inventions and devices of Patent Documents 1 to 3 have various shapes and structures, but none of them are rulers that can be used to count the number of characters or substitute for memorization sheets. Ta.

In order to solve the above problem, the invention of claim 1 provides a ruler 2 having a stop hole 2 and a hollowed out part 2, a ruler 3 having a fixed hole 3 and a hollowed out part 3, and a ruler 3 having a fixed hole 4 and a hollowed out part 4. A memorization film 5 having a ruler 4 and a stop hole 5 is provided, the stop hole 2, the stop hole 3, the stop hole 4 and the stop hole 5 are fixed with a stopper, and the ruler 2 and the ruler 3 are provided. , the ruler 4 and the memorization film 5 are rotatably supported at one point around the stopper.

According to the present invention, it is possible to easily align the distributed prints to a line slightly inside the notebook while maintaining the ability to store them in a pencil case, etc., and it is possible to paste the prints neatly without protruding from the notebook. become. Furthermore, it is possible to easily create a frame for an answer column for a question with a specified number of characters, making it possible to study efficiently. Also, it becomes possible to measure the length and draw lines of long objects. Furthermore, since the memorization sheet is rotatably fixed with a ruler and a stopper, its whereabouts will never be unknown.

Embodiments of the present invention will be described below with reference to the accompanying drawings. The following embodiments are illustrative for explaining the present invention, and are not intended to limit the present invention only to the embodiments. Further, the present invention can be modified in various ways without departing from the gist thereof. Furthermore, in each drawing, the same components are given the same reference numerals as much as possible, and duplicate explanations will be omitted.

<Embodiment>
FIG. 1 shows an overall view of a multi-functional ruler according to an embodiment of the present invention, FIG. 2 shows an exploded view of the surface of a multi-functional ruler according to an embodiment of the present invention, and FIG. 3 shows a multi-functional ruler according to an embodiment of the present invention. The back side of the exploded view is shown for each. The stop holes 21, 31, 41, and 51 are fixed by a stopper 1, and a ruler 2, a ruler 3, a ruler 4 having different lengths in the form of strips and a memorization film 5 are rotatably supported at one point. The three types of rulers have hollowed out portions 22, 32, and 42 having different lengths in the center in the lateral direction.

Here, as an example, a case is shown in which ruler 2 and ruler 3 are combined for pasting on a B5 notebook, and ruler 3 and ruler 4 are combined for pasting on a B6 notebook. The widths W of the ruler 2, ruler 3, ruler 4, and memorization film 5 are preferably the same size, but may be different within a few mm. . Further, the width W is most preferably 30 mm, as is the case with popular rulers, but the size is not particularly determined. The memorization film 5 is preferably made of a red translucent material used for learning purposes.

In addition, the length H2 of the ruler 2, the length H3 of the ruler 3, the length H4 of the ruler 4, and the length H5 of the memorization film 5 are not particularly determined, but considering portability, etc., H2 is around 260 mm, respectively. Preferably, H3 is around 190 mm, H4 is around 120 mm, and H5 is around 150 mm.

On the front side of the ruler, character count guides 201 to 204, 301 to 304, 311 to 313, 401 and 402 may be written in order to make it easier to count the number of characters shown in FIG. Scales 23, 33, and 43 may be written as shown.

As shown in the figure, the ruler 2, the ruler 3, and the ruler 4 each have cutouts 22, 32, and 42 having the same width and different vertical dimensions. The cutout portions 22, 32, and 42 may be aligned with the character number guides 201 to 204, 301 to 304, 311 to 313, 401, and 402, and the vertical dimension may correspond to the length of the desired number of characters.

By drawing lines along the cut-out portions 22, 32, and 42 and marking them in accordance with the scale of the character count guide, an answer column specifying the 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 obtained even if each letter is made independent like a square window frame.

<Example 1>
Next, a print cutting method will be explained using FIGS. 4 and 5. 4 and 5 show how to use a ruler for B5 print 6. As shown in FIG. 4, the rulers 2 and 3 are opened in an L-shape, and placed so that the axis of rotation is aligned with the lower left corner of the print 6, and the center of the ruler in the width direction is at the edge of the print 6.

By drawing a line along the inside of the L-shape formed by rulers 2 and 3, the cutting location is clearly indicated. Then, as shown in Figure 5, rotate 180 degrees while maintaining this L-shape, align the stopper with the upper right corner of the print 6, and draw a line along the inside of the inverted L-shape to mark the cut point. Can be made clear.

<Example 2>
6 and 7 show how to use a ruler for the B6 print 7. Using ruler 3 and ruler 4, you can clearly mark the cutting location in the same way as the B5 version. Although the B5 and B6 sizes are used here, it goes without saying that the same effect can be obtained by adjusting the print size to the desired print size, or by combining three or more types.

<Example 3>
FIG. 8 is an explanatory diagram regarding the creation of an answer column for a question specifying the number of characters. As mentioned above, the three types of rulers 2, 3, and 4 are provided with hollow parts 22, 32, and 42, and character number guides 201 to 204, 301 to 304, 311 to 313, 401, and 402 are written on the surface. has been done.

As shown in the figure, when the words "This invention facilitates learning" are superimposed on the cutout 22, it can be easily determined that the number of characters is 15 from the character number guides 201 to 204. As an example, based on characters written on a 10 mm grid notebook that is often used for learning, there are hollowed out parts 22, 32 and 42, and character number guides 201 to 204, 301 to 304, 311 to 313, 401 and 402 may be prepared, or other sizes may be used as a base.

<Example 4>
FIG. 9 shows a case where the length of a long object is measured. When the ruler 3 is rotated 180 degrees with respect to the ruler 2, the scale written on the back side of the ruler becomes continuous, and it can be transformed into a 42 cm ruler, as an example.

<Example 5>
FIG. 10 shows how to use the memorization film 5. The three types of rulers are kept in the same posture, and only the memorization film 5 is rotated by 90 degrees. By moving the ruler up and down while pressing the longitudinal edge of the ruler against the edge of the notebook, the memorization film 5 can be moved along the horizontally written lines, improving convenience. If you want to write vertically, just rotate the entire page 90 degrees so that it aligns with the top edge of the notebook.

Here, the width of the memorization film in the lateral direction is the same as that of the ruler, but if the memorization film is made of a material that is hard to break, it is possible to install a memorization film wider than the width of the ruler.

Here, for simplicity, three types of rulers and the memorization film 5 are rotatably fixed with a stopper 1. Attachment and detachment can be facilitated by using known techniques such as screws. Alternatively, by making the rotating part into an inverted V shape, for example by adding a magnet to the inverted V part of the memorization film 5, and by making the inverted V part of the other rulers made of iron, attachment and detachment can be facilitated.

Furthermore, it goes without saying that in addition to the functions described here, it is also possible to incorporate known techniques such as a paper knife function, a protractor function, and a light shielding plate function.
