Abstract

PROBLEM TO BE SOLVED: To provide a seal capable of sealing a plurality of small alphabet characters in the state of keeping the vertical relative positions of the characters.SOLUTION: A seal having small alphabet characters printed thereon includes a stamp surface where characters have been printed and an upper surface opposite the stamp surface. In the upper surface, characters identical to the printed characters are displayed. A position of one of four reference lines, i.e., a descender line, a base line, a mean line, and an ascender line of alphabet with respect to the characters printed in the stamp surface and a contour of a seal, or a position of a mark formed in the seal are matched with each other.

Description

  The present invention relates to a stamp in which lowercase letters of the alphabet are engraved as stamps.

  In primary education, character learning using a stamp may be performed. For example, a plurality of stamps corresponding to each character constituting the Japanese syllabary are prepared, and a word to be stamped is designated for the child. The child finds the size of each character composing the designated word, and stamps the characters composing the word in that order. Through such work, the child can learn while enjoying the Japanese syllabary. In recent years, the trend of early English education has risen, and alphabet learning using a stamp is sometimes performed.

  In character learning using such a character, hiragana and katakana basically have a constant vertical width regardless of the character. For this reason, if one reference line is drawn on the paper for stamping the stamp, the child can make a stamp so that each character constituting the designated word is aligned horizontally along the reference line.

Japanese Utility Model Publication No. 6-63336

  However, the lower and upper widths of the lowercase letters of the alphabet vary depending on the characters. More specifically, the relative positions of the upper end and the lower end of the character are determined to be different depending on the character. For example, the character “g” has the same upper end position as the character “a”, but the lower end position is relatively lower. For this reason, unlike Hiragana and Katakana, a plurality of characters cannot be imprinted so as to be arranged side by side while maintaining the original relative position in the vertical direction of the characters (hereinafter also simply referred to as relative position). In such a situation, the child cannot learn the relative position specific to the lower case letters of the alphabet.

  For this reason, there is a need for a stamp that can stamp lowercase letters of a plurality of alphabets in a state where the upper and lower relative positions are maintained. Also, it is desirable that the stamping operation with such a stamp can be performed as easily as possible. Further, it is desirable that the stamp can be easily manufactured.

  2. Description of the Related Art Conventionally, various kinds of stamps with positioning marks for preventing characters (imprints) from tilting are known (for example, Patent Document 1 above). However, these are a method for easily grasping the upper side of the character and a method for correcting the circumferential displacement of the cylindrical stamp, and cannot satisfy the above-described requirements. The above-mentioned problem is not limited to the sign used for education, but is common to the sign stamped with the lower case letters of the alphabet.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as, for example, the following forms.

  The first aspect of the present invention is provided as a stamp in which lowercase letters of the alphabet are engraved as stamps. This stamp has a stamped surface on which a stamp is engraved and an upper surface opposite to the stamped surface. On the top surface, the same characters as the seal are displayed. The position of one of the four reference lines of the alphabet's descender line, base line, mean line, and ascender line, and the position of the contour of the stamp, or the stamp of the stamp. The mark position is aligned.

  According to such a form, the position of the paper-side reference line and the position of the mark formed on the stamp on the stamped paper (paper for imprinting) on which the paper-side reference line is represented along the direction in which the characters are arranged. By aligning and stamping so as to be aligned, the position of the paper-side reference line and the position of one reference line of the stamp are also aligned. As a result, it is possible to impress a plurality of lowercase letters of the alphabet while maintaining the relative positions of the letters in the vertical direction.

  As a 2nd form of this invention, in the 1st form, the mark may be attached | subjected to the stamp. Of the position of the contour of the stamp and the position of the mark attached to the stamp, the position of the mark may be aligned with the position of one reference line. According to this form, it is easy to set one reference line as a base line or a mean line.

  As a third aspect of the present invention, in the second aspect, one reference line may be a baseline. According to such a form, it is possible to obtain a stamped object (a stamped stamped sheet) in which characters are easy to see (easy to read). Moreover, if this type of stamp is used for education, the relative position of each character with reference to the baseline can be suitably learned from the stamped object. The baseline is an effective educational method because it is an important line that serves as a standard in writing the lowercase letters of the alphabet.

  As a fourth form of the present invention, in the second or third form, the mark may include one reference line attached to a character represented on the upper surface. According to such a form, the person who performs the stamp can easily align one reference line with the sheet-side reference line while grasping the stamp and looking at the stamped sheet from directly above the stamped sheet.

  As a fifth aspect of the present invention, the stamp in any one of the second to fourth aspects has a columnar shape in which the marking surface and the upper surface are both end surfaces, and a side surface is formed between the marking surface and the upper surface. It may be. The mark may be attached to the marking side of the side surfaces. According to such a form, since one reference line is attached at a position close to the stamped paper at the time of stamping, it is easy for the person who stamps to see one reference line and the paper side reference line while looking at the side. Can be matched.

  As a sixth aspect of the present invention, the stamp in any one of the second to fourth aspects includes a plate-shaped bottom portion having a marking surface and an upper surface, and a position avoiding the characters represented on the upper surface of the bottom portion. And a grip portion for gripping formed to extend in the direction from the marking surface toward the upper surface. The mark may include one reference line attached to the character represented on the upper surface. According to such a form, when stamping, the stamped paper and the top surface with the mark are in very close proximity. Therefore, the person who makes the stamp can very easily align one reference line with the paper-side reference line when making the stamp.

  As a seventh aspect of the present invention, in the sixth aspect, the bottom may be formed of a transparent member. According to this form, one reference line and the paper side reference line can be more easily aligned. Moreover, since the engraved stamp can be confirmed from the upper surface side, it is easy to imagine the position and size of the character to be stamped on the stamped paper.

  As an eighth aspect of the present invention, in any one of the first to seventh aspects, the same character as the stamp displayed on the upper surface may be expressed in the same size as the stamp. It is easy to imagine the position and size of the stamped characters on the stamped paper.

  The ninth aspect of the present invention is provided as a signature set including the signature of any one of the first to eighth aspects. This set of stamps comprises 26 stamps in which each of the 26 characters constituting the lowercase letters of the alphabet is engraved as a stamp in correspondence with one character per stamper. According to such a stamp set, it is possible to create a stamp containing an arbitrary word expressed in alphabet. In addition, the same effect as any one of the first to eighth embodiments is obtained.

  The tenth form of the present invention is provided as a method of manufacturing a stamp in which lowercase letters of the alphabet are engraved as stamps. The manufacturing method includes a first step of preparing a rubber member on which a stamp surface engraved with a stamp is formed, and a substrate having an upper surface for representing the same character as the stamp, and an upper surface of the substrate. A second step of adhering the rubber member to the surface opposite to the surface, and an alphabet descender line, base line, mean line and And a third step of adding a mark at a position aligned with the position of one of the four reference lines of the ascender line. According to this manufacturing method, after the second step, it is only necessary to place a mark at a position that matches the one reference line for the seal stamped on the rubber member bonded by the third step. The positioning accuracy when the rubber member is bonded is not limited. Therefore, the stamp can be easily manufactured.

It is explanatory drawing which shows the relative position of the up-down direction of the small letter of an alphabet carved in the stamp 20 as an Example of this invention. It is the perspective view which looked at the stamp 20 from the upper surface 30a side. It is the perspective view which looked at the stamp 20 from the stamping surface 41 side. It is the perspective view which looked at the stamp 120 as 2nd Example from the front side. It is the perspective view which looked at the stamp 120 from the side.

  A. Example:

  FIG. 1 shows the relative positions in the vertical direction of lower case letters (hereinafter, also simply referred to as lower case letters) engraved in a stamp 20 as an embodiment of the present invention. As shown in the drawing, the lowercase letters “a” to “z” have different vertical widths depending on the characters, and the relative positions of the characters are also different. This is because the shape for each character is defined by the descender line DL, the base line BL, the mean line ML, and the ascender line AL. In the present application, the alphabet is not limited to the English alphabet, but includes alphabets of various languages such as French, German, Spanish, and Russian.

  Of the lowercase letters “a” to “z”, a, c, e, i, m, n, o, r, s, u, v, w, x, z are the lower end of the character positioned at the baseline BL And the upper end is located on the mean line ML (except for the point above i). The width between the base line BL and the mean line ML is also referred to as X height. On the other hand, in b, d, f, h, k, l, the upper end of the character is positioned on the ascender line AL. For g, j, p, q, and y, the lower part of the character is positioned on the descender line DL. In t, the upper end of the character is positioned between the mean line ML and the ascender line AL.

  The judgment 20 is provided as a judgment set including a set of 26 judgments 20 in which these 26 lowercase letters are engraved with a correspondence of one letter per judgment 20. Hereinafter, the configuration of the stamp 20 will be described.

  2 and 3 show the appearance of the stamp 20. As shown in the figure, the stamp 20 includes a base material 30 and a rubber member 40. The base material 30 is formed in a substantially prismatic shape extending in one direction, and an upper surface 30a and a bottom surface 30b are formed at both ends in the one direction. Four side surfaces 30c to 30f are formed between the upper surface 30a and the bottom surface 30b. The base material 30 can be formed of any material having a strength that does not deform during stamping, such as wood or resin.

  A plate-like rubber member 40 is bonded to the bottom surface 30b with an adhesive. As shown in FIG. 3, a marking surface 41 is formed on the surface of the rubber member 40 opposite to the base material 30. In this example, the letter “g” is engraved as a seal.

  On the side surface 30d on the upper side of the stamp “g”, a groove-shaped cut 32 is formed along a direction orthogonal to the side surface 30c. This notch 32 is formed so that it can be easily grasped that the side surface 30d is the upper side of the stamp.

  A mark 33 is formed on the two side surfaces 30c and 30e corresponding to the horizontal direction of the stamp. This mark 33 is attached along the direction from the marking surface 41 toward the upper surface 30a at a position matching the baseline BL of the stamp “g”. The mark 33 is biased toward the marking surface 41 of the marking surface 41 and the upper surface 30a. In this embodiment, the mark 33 is drawn with ink.

  On the upper surface 30a, the same letter “g” as the stamp is represented in the same direction. In this embodiment, a sticker 31 printed with a letter “g” is attached to the upper surface 30a. However, it may be printed directly on the upper surface 30a. In the present embodiment, the letter “g” shown on the seal 31 is the same size as the stamp “g” carved on the stamp face 41. On the seal 31, a descender line DL, a base line BL, a mean line ML, and an ascender line AL are represented at appropriate positions with respect to the letter “g”. In the present embodiment, the baseline BL shown on the seal 31 is aligned with the baseline of the stamp “g” engraved on the stamp face 41. That is, in the character height direction of the stamp “g”, the position of the baseline BL shown on the sticker 31 and the position of the mark 33 coincide. By doing so, it is easy to imagine the position on the paper on which the seal impression is formed when the stamp 20 is gripped and the seal is formed while viewing the upper surface 30a from above.

  According to the stamp 20, the reference line (hereinafter also referred to as a sheet-side reference line) represented on a sheet (hereinafter also referred to simply as a sheet) on which the stamp is imprinted is aligned with the mark 33. Can be used to obtain imprints of lowercase letters “a” to “z” at appropriate relative positions (see FIG. 1) with the paper-side reference line as the base line BL. The lowercase letters arranged in accordance with the base line BL are very easy to read, and the difference in relative position for each character can be easily grasped at a glance. Therefore, it is very suitable for lower case education in primary education. The paper-side reference line may be expressed on a blank paper with a writing instrument or a printer, or a ruled line printed on a notebook may be used.

  Further, since the mark 33 is attached to the marking surface 41 side, the distance between the mark 33 and the paper side reference line is short, and both can be easily aligned. Moreover, since the mark 33 is attached to the two side surfaces 30c and 30e, alignment can be performed from either side.

  Moreover, since the character represented on the sticker 31 is the same size as the stamp, it is easy to imagine the position and size of the character to be stamped on the paper. In addition, since the base line BL and the like are displayed on the seal 31 together with the characters, when the stamp 20 is used for education, the work for finding the stamp 20 for a predetermined character or the stamp 20 that has been found is stamped. Through this work, the positional relationship between the characters and the baseline BL can be naturally learned. It is also effective to display the order of characters on the sticker 31 together.

  The above-described stamp 20 can be manufactured as follows. First, a rubber member 40 having a stamped surface 41 engraved with a stamp and a base material 30 having an upper surface 30a for displaying the same characters as the stamp are prepared.

  Next, the rubber member 40 is bonded to the bottom surface 30 b of the base material 30. Then, a mark 33 is attached to a position in the base material 30 to which the rubber member 40 is bonded, in alignment with the position of the base line BL with respect to the stamp engraved on the marking surface 41. Finally, the seal 31 is attached to a position on the upper surface 30a where the base line BL and the mark 33 shown on the seal 31 are aligned. In this way, the stamp 20 is completed.

  According to such a manufacturing method, the mark 33 may be attached at a position that matches the base line BL with respect to the seal stamped on the bonded rubber member 40. Therefore, the positioning accuracy when the rubber member 40 is bonded is questionable. I will not. Therefore, the stamp 20 can be easily manufactured. When the position of the base line BL with respect to the stamp is not aligned with the position of the base line BL shown on the seal 31, the seal 31 is attached to the upper surface 30a in advance before the rubber member 40 is bonded. May be.

B. Second embodiment:
4 and 5 show the appearance of the stamp 120 as the second embodiment. In the following, only differences from the first embodiment will be mainly described. As illustrated, the stamp 120 includes a base material 130 and a rubber member 140. The base material 130 includes a bottom part 134 and a grip part 135. The bottom portion 134 has a plate shape, and a rubber member 140 is bonded to the bottom surface 130b. A marking surface 141 is formed on the surface of the rubber member 140 opposite to the side to be bonded. In this embodiment, the letter “a” is engraved as a seal (not shown). An upper surface 130a is formed on the opposite side of the bottom portion 134 from the bottom surface 130b.

  On the upper surface 130a, the same character “a” as that of the stamp “a” is displayed, as in the embodiment. The base line BL, the mean line ML, and the ascender line AL are attached to the character “a” at appropriate positions. Although illustration is omitted, when the stamp is “g”, the letter “g” is represented on the upper surface 130a, and the descender line DL, the base line BL, and the mean line ML are attached. That is, the size of the upper surface 130a may be different depending on the character, and the region where the character is not formed can be omitted.

  Of the base line BL, the mean line ML, and the ascender line AL given to “a” represented on the upper surface 130a, the base line BL is displayed in a color different from the mean line ML and the ascender line AL. The base line BL functions as a mark 133 corresponding to the mark 33 of the first embodiment.

  The grip portion 135 is formed to extend from the position of the bottom portion 134 avoiding the character “a” represented on the upper surface 130a in the direction from the marking surface 141 toward the upper surface 130a. In the present embodiment, the grip portion 135 is formed in a long plate shape. The grip 135 is formed to extend from the upper end of the letter “a” in the upper surface 130a. The grip part 135 is a part where the stamper grips the base material 130. By forming the grip portion 135 at such a position, the stamper can view the position of the mark 133 while looking at the front side 130a at the time of the seal, that is, the grip portion 135 does not disturb the visibility of the upper surface 130a. Can be combined and convenient.

  The grip part 135 includes a bending part 136 and a flat plate part 137. The base end of the bending portion 136 is formed integrally with the bottom portion 134, and the distal end of the bending portion 136 is formed integrally with 137. The curved portion 136 has a curved shape that warps on the back side (the direction opposite to the bottom portion 134). The flat plate portion 137 has a flat plate shape parallel to the vertical direction. In the present embodiment, the grip portion 135 (the curved portion 136 and the flat plate portion 137) is formed of an elastic resin. When the stamper grips the flat plate portion 137 and presses it downward for printing, the bending portion 136 bends forward (in the direction opposite to the back surface). As a result, the pressing force easily acts uniformly on the entire surface of the rubber member 140, and can be stably stamped.

  According to the stamp 120, the sheet and the upper surface 130a to which the mark 133 (baseline BL) is attached are slightly separated from each other by a distance corresponding to the thickness of the bottom portion 134 and the rubber member 140. It becomes a state. Therefore, the alignment between the mark 133 and the paper side reference line is very easy.

C. Variations:
C-1. Modification 1:
In the first embodiment, the rubber member 40 is not necessarily required, and the stamp may be directly engraved on the bottom surface 30b. The same applies to the second embodiment.

C-2. Modification 2:
In the second embodiment, the bottom portion 134 and the rubber member 140 may be formed of a transparent member. This makes it easier to align the mark 133 and the paper-side reference line. Further, no characters may be displayed on the upper surface 130a. By doing so, the stamp on the stamp surface 141 can be confirmed from the upper surface side, so that it is easy to imagine the position and size of the character to be stamped on the paper. In addition, in a state where ink is attached to the stamp surface 141, the stamp can be easily visually recognized from the upper surface 130a side.

  Such a form can also be applied to the first embodiment. However, since the distance between the mark 133 and the paper-side reference line is much smaller in the second embodiment, it is a matter of course that the above-described effect is remarkably large. In the case where the stamp is engraved on the bottom surface 130b, the bottom portion 134 may be formed of a transparent member.

C-3. Modification 3:
The mark 33 (133) is not limited to ink and can be attached by various methods. For example, a line-shaped seal or a seal printed with a line-shaped mark may be pasted. Or you may form a groove | channel in the side surfaces 30c and 30e, or may form a protrusion part.

C-4. Modification 4:
In the above-described embodiment, the positions of the mark baseline BL and the mark 33 (133) are aligned, but instead of the baseline BL, any one of the descender line DL, the mean line ML, and the ascender line AL, The position with the mark 33 (133) may be aligned. Of course, two or more marks corresponding to two or more of the descender line DL, the base line BL, the mean line ML, and the ascender line AL may be attached to the stamp 20 (120).

  Of course, the mark 33 (mark 133) is not essential, and the outline of the upper surface 30a (130a) may be aligned with the descender line DL or the ascender line AL. As in the second embodiment, when the character region represented on the upper surface 130a differs depending on the character, the outline of the upper surface 130a can be aligned with the base line BL or the mean line ML depending on the character.

D. Other forms:
The above-described modification 2 is not limited to a stamp whose lowercase letters are engraved as stamps, but is realized as a stamp (stamp) where any characters, symbols, or figures (including pictures and patterns) are engraved. Is also possible. In this way, since the engraved characters and the like can be confirmed from the upper surface side, it is possible to solve the general problem in this field of making it easy to imagine the position and size of the stamped characters and the like on the paper.

The embodiments of the present invention have been described above based on some examples. However, the above-described embodiments of the present invention are for facilitating the understanding of the present invention and limit the present invention. It is not a thing. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes the equivalents thereof. Moreover, in the range which can solve at least one part of the subject mentioned above, or the range which exhibits at least one part of an effect, the combination of each component described in the claim and the specification, or omission is possible. .
For example, in the first embodiment described above, the same characters as the stamp do not necessarily have to be represented on the upper surface 30a. In this case, for example, in order to identify the plurality of stamps 20, the character may be represented on at least one of the side surfaces 30c to 30f.

20, 120... 30, 130... Base material 30 a, 130 a .. upper surface 30 b, 130 b .. bottom surface 30 c, 30 d, 30 e, 30 f .. side surface 31 ... seal 32 ... notch 33, 133. 141 ... marking surface 134 ... bottom 135 ... gripping part 136 ... curved part 137 ... flat plate part DL ... descender line BL ... base line ML ... mean line AL ... ascender line
