Description

[Technical Field]

[0001] The present invention relates to a flashcard book. [Background technology]

[0002] A conventional flashcard book is made up of a number of rectangular cards bound together at their short edges with a ring-shaped binder. Such flashcards are typically used by holding the flashcard book in one hand and flipping through the cards one by one with the other.

[0003] For example, Patent Documents 1 and 2 listed below propose a flashcard that can be used with one hand.

[0004] The vocabulary book (learning memory book) shown in Patent Document 1 is designed so that multiple cards are held in a curved state around the index finger, and the cards are turned over one by one with the thumb of the same hand, using the notches provided alternately on each card.

[0005] The flashcard disclosed in Patent Document 2 is held in one hand, and instead of turning over the cards, the cards are slid out one by one with the thumb of the same hand. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Utility Model Application Publication No. 55-47303 [Patent Document 2] Utility Model Registration No. 3081103 Summary of the Invention [Problem to be solved by the invention]

[0007] However, it is not easy to hold multiple cards in a curved state in one hand and turn over the cards one by one, as with the flashcard in Patent Document 1. Also, it is not easy to slide out only the top card using only your thumb, as with the flashcard in Patent Document 2, and multiple cards may slide out together.

[0008] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a flashcard book that allows cards to be easily turned over one by one with one hand. [Means for solving the problem]

[0009] In order to solve the above problem, the present invention provides a flashcard book including a plurality of substantially rectangular cards and a binding device for binding the plurality of cards at a plurality of locations on the long sides thereof, A notch is provided on one short side of each card, To provide a rote card book in which the position of the notch on the one short side of each card is different from the position of the notch on the one short side of the next card.

[0010] In the rote card book of the present invention, as described above, the cards are bound with binding devices at multiple locations along their long sides. In this case, when turning over a card, the card rotates around the long side bound with binding devices at multiple locations, allowing for more stable turning over than in conventional products in which the short sides are bound with a single binding device. Furthermore, in this invention, a notch is provided on one short side of each card, and the position of the notch on one short side of each card is different from the position of the notch on one short side of the next card. In this case, the next card is exposed through the notch on the top card, so that by holding the next card with a finger through the notch on the top card and inserting a finger between the top card and the next card, only the top card can be easily turned over. As described above, by binding the long sides of the approximately rectangular cards with binding devices at multiple locations and making the notches on adjacent cards different in position, it is possible to easily turn over the cards one by one with the fingers of the same hand while holding the rote card book in one hand.

[0011] The above-mentioned flashcard book has a cover bound together with a plurality of cards with a binder, and the cover preferably has a finger insertion section into which a finger can be inserted along the long side of the card. In this case, by inserting a finger (for example, an index finger) along the long side into the finger insertion section provided on the cover, the flashcard book can be easily held stably in one hand.

[0012] In the above-mentioned flashcard book, it is preferable that a notch is also provided on the other short side of each card, and the position of the notch on the other short side of each card is different from the position of the notch on the other short side of the next card, and the finger insertion section allows fingers to be inserted from both sides of the long side of the card. In this case, it is possible to easily turn over the cards one by one while holding the flashcard book in one hand, either right or left.

[0013] The binding device can be configured, for example, with a pair of rings inserted into a pair of holes provided in a plurality of cards. In this case, if the rings are free to move, the stack of multiple stacked cards will not be stable, which may make it difficult to turn over the cards. Therefore, it is preferable to provide the above-mentioned flashcard book with a collapse prevention part that abuts the pair of rings from the inside of the long sides and prevents each ring from collapsing inward along the long sides. In this way, by preventing each binding device from collapsing inward along the long sides, the shape of the stack of multiple cards will be stable, making it easier to turn over the cards.

[0014] Furthermore, when the binding device is a pair of rings inserted into a pair of holes provided in the plurality of cards, it is preferable that each ring be movable between a usage state in which the long sides of the cards are positioned on the inner periphery of each ring and a storage state in which the short sides of the cards are positioned on the inner periphery of each ring while the pair of rings are inserted into the pair of holes in the cards. When using the flashcard book, the rings are set in the usage state (see dotted lines in FIG. 12 ) to allow the cards to be turned over. On the other hand, when the rings are set in the storage state (see solid lines in FIG. 12 ), the cards get caught on the rings and cannot be turned over. Therefore, when the flashcard book is not in use, for example, when carrying it in a bag, the rings are set in the storage state to prevent the cards from becoming disorganized. [Effects of the Invention]

[0015] As described above, the flashcard book of the present invention makes it possible to easily turn over cards one by one with one hand. [Brief explanation of the drawings]

[0017] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0018] 1 to 4 show a flashcard book 1 as a flashcard book according to one embodiment of the present invention. The flashcard book 1 has a plurality of cards 2, a cover unit 10 integrally having a front cover 11, a back cover 12, and a spine 13, and a binding device for binding them together. In this embodiment, a pair of rings 3 is used as the binding device. Note that, for the sake of convenience, the upper and lower sides in FIGS. 1 and 2 will be referred to as "upper" and "lower" respectively below, but this is not intended to limit the manner in which the flashcard book 1 can be used.

[0019] The multiple cards 2 are generally rectangular. In this embodiment, the multiple cards 2 are made up of a first card 2A (see FIG. 5) and a second card 2B (see FIG. 6) that are different in shape. A pair of holes 2a are provided near the upper long sides of the first card 2A and the second card 2B, spaced apart in the long side direction. Cutouts 2b and 2c are provided on both short sides of the first card 2A and the second card 2B. The cutouts 2b on each short side of the first card 2A and the cutouts 2c on each short side of the second card 2B are provided in different positions. In the illustrated example, the cutouts 2b are provided at the bottom end of each short side of the first card 2A, and the cutouts 2c are provided at the top end of each short side of the second card 2B. A card stack made up of the multiple cards 2 is formed by alternately stacking the first card 2A and the second card 2B.

[0020] The front cover 11 and back cover 12 are rectangular in shape, roughly the same as the card 2, and have a pair of holes 11a, 12a spaced apart in the long-side direction near the upper long sides (see FIGS. 1 and 2). Holes 11a, 12a overlap the entirety of hole 2a of card 2 when viewed in the thickness direction. In the illustrated example, holes 11a, 12a are elongated holes that extend from near the bottom end of hole 2a of card 2 to above hole 2a (to the upper long side in the illustrated example). By stacking the front cover 11, card 2, and back cover 12 and inserting rings 3 into the holes 2a, 11a, and 12a, the card 2, front cover 11, and back cover 12 are bound together at multiple locations on the upper long sides with the pair of rings 3.

[0021] As shown in FIG. 1, the cover 11 has a main body 11c and a pocket-forming portion 11d superimposed on the front side of the main body 11c (the side opposite the card 2). The main body 11c is rectangular, with a pair of holes 11a formed in the upper long side. The upper part of the pocket-forming portion 11d is disposed between the pair of holes 11a, and the lower part has a larger dimension in the long side direction than the upper part. Both upper and lower ends of the pocket-forming portion 11d are connected to the main body 11c, and the middle part in the vertical direction (the area excluding both ends) is not joined to the main body 11c. By widening the gap between the main body 11c and the pocket-forming portion 11d of the cover 11, a finger insertion portion 11b is formed into which a finger can be inserted in the long side direction (see FIG. 9).

[0022] The cover unit 10 has a tipping prevention portion 14. In this embodiment, the tipping prevention portion 14 is provided between a pair of rings 3 on the spine 13 (see FIG. 1). The tipping prevention portion 14 is disposed at a position where it can abut against each ring 3 from the center of the long side. In the illustrated example, the dimension of the tipping prevention portion 14 in the long side direction is approximately equal to the long side distance between the pair of rings 3, i.e., the long side distance between the pair of holes 2a of the card 2 and the pair of holes 11a of the cover 11. In the side view of the flashcard 1 shown in FIG. 4, the tipping prevention portion 14 overlaps a portion of the ring 3. In the illustrated example, the tipping prevention portion 14 has a triangular prism shape, and its apex is disposed above the ring 3. As described above, each ring 3 is supported from the inside in the long side direction by the tipping prevention portion 14, and therefore, each ring 3 is prevented from tipping inward in the long side direction from a state in which it is arranged parallel to the up-down direction (see FIG. 1).

[0023] In this embodiment, the cover 11, back cover 12, and spine 13 are integrated into a cover unit 10. As shown in FIG. 7, the cover unit 10 of this embodiment is formed from a single flat piece of cardboard 20. Specifically, the cardboard 20 integrally includes the back cover 12, the spine 13, the main body 11c and bag-forming portion 11d of the cover 11, and a first portion 14a, a second portion 14b, a third portion 14c, and a fourth portion 14d that form the collapse prevention portion 14. Double-sided tape 21 is attached to the surfaces of the third portion 14c and the fourth portion 14d. As shown in FIG. 8, the cover unit 10 is formed by folding the boundaries of each portion of the cardboard 20. In the illustrated example, the fourth part 14d of the anti-tip part 14 is attached to the back surface of the first part 14a via double-sided tape 21 to form a triangular prism-shaped anti-tip part 14, and the third part 14c of this anti-tip part 14 is attached to the spine 13 via double-sided tape 21.

[0024] The following describes how to use the above-mentioned wordbook 1.

[0025] First, as shown in Fig. 9, the gap between the main body 11c and the pocket-forming portion 11d of the cover 11 is widened, and a finger (for example, an index finger) is inserted into the finger insertion portion 11b formed between them from the long side direction. This integrates the finger and the flashcard book 1, making it easier to hold the flashcard book 1 in one hand.

[0026] Then, as shown in FIG. 10, the cover 11 is turned over to expose the card 2. In this state, the next card 2 (second card 2B) is exposed from the notch 2b provided at the bottom end of the short side of the foremost card 2 (first card 2A). The thumb of the hand (the right hand in the illustrated example) with its fingers inserted into the finger insertion section 11b of the cover 11 is used to press the next card 2 (second card 2B) through the notch 2b of the foremost card 2 (first card 2A) and insert the thumb between the foremost card 2 (first card 2A) and the next card 2 (second card 2B). Then, the foremost card 2 (first card 2A) is turned over by lifting it with the thumb (see FIG. 11).

[0027] Similarly, while holding down the next card 2 (first card 2A) through the notch 2c provided at the top end of the short side of the foremost card 2 (second card 2B), insert your thumb between the foremost card 2 (second card 2B) and the next card 2 (first card 2A) and lift up the foremost card 2 (second card 2B) with your thumb to turn over this card 2. By repeating the above, you can easily turn over the cards 2 one by one with one hand.

[0028] 9 to 11 show the case where the flashcard 1 is handled with the right hand, but the flashcard 1 of this embodiment can also be handled with the left hand. Specifically, in the flashcard 1, the finger insertion section 11b of the cover 11 penetrates in the long side direction, so that the fingers of the left hand (for example, the index finger) can be inserted from the left side of FIG. 1. Also, as shown in FIGS. 10 and 11, the cards 2 have cutouts 2b and 2c on both short sides. Therefore, with the index finger of the left hand inserted in the finger insertion section 11b, the cards 2 can be turned over one by one with the thumb of the left hand using the cutouts 2b and 2c on the left short side of each card 2.

[0029] In the above-described flashcard 1, the cards 2 are bound with rings 3 at multiple locations (two locations in this embodiment) on the long sides, which prevents the cards 2 from sliding or rotating around the short sides. This allows the cards 2 to rotate stably around the long sides, making it easier to turn the cards 2. In particular, in this embodiment, the fall prevention unit 14 prevents the pair of rings 3 from falling inward along the long sides, stabilizing the shape of a card stack made up of many stacked cards 2. This further stabilizes the rotation of the cards 2, making it even easier to turn the cards 2.

[0030] In this embodiment, as shown in FIG. 12 , the ring 3 is movable between a usage state (see dotted line) in which the upper long side of the card 2 is positioned on the inner periphery of the ring 3 while the ring 3 is inserted into the hole 2a of the card 2, and a storage state (see solid line) in which the short side of the card 2 is positioned on the inner periphery of the ring 3. In other words, the positions of the hole 2a of the card 2, the hole 11a of the cover 11, and the hole 12a of the back cover 12, as well as the diameter of the ring 3, are set so that the ring 3 can be moved between the usage state and the storage state. When the flashcard 1 is used, the ring 3 is set to the usage state, and the card 2 is rotatable around the upper long side (see FIGS. 10 and 11 ). On the other hand, when the ring 3 is set to the storage state, the ring 3 restricts rotation of the card 2 around the long side, preventing the card 2 from being turned over. Therefore, when the flashcard 1 is not in use, the ring 3 is set to the storage state, so that the cards 2 do not come apart when the flashcard 1 is stored in a bag or the like.

[0031] The present invention is not limited to the above-described embodiment. Other embodiments of the present invention will be described below, but redundant description of points similar to those of the above-described embodiment will be omitted.

[0032] In the above embodiment, the notches 2b and 2c are provided on both short sides of each card 2. However, this is not limited to this, and the notches 2b and 2c may be provided on only one short side of each card 2. Furthermore, in the above embodiment, the finger insertion section 11b allows fingers to be inserted from both long side directions. However, this is not limited to this, and the finger insertion section 11b may be configured so that it can be inserted from only one long side direction, and the other long side end may be closed. For example, if the notches 2b and 2c are provided only on the right short side of the card 2, and fingers can be inserted into the finger insertion section 11b only from the right side, the card will be a flashcard for right-handed people. On the other hand, if the notches 2b and 2c are provided only on the left short side of the card 2, and fingers can be inserted into the finger insertion section 11b only from the left side, the card will be a flashcard for left-handed people.

[0033] Furthermore, in the above embodiment, finger insertion portion 11b is formed by main body 11c and bag forming portion 11d, but this is not limiting, and finger insertion portion 11b may be formed by, for example, a ring or hook fixed to cover 11. Furthermore, finger insertion portion 11b may be omitted if not particularly required.

[0034] Furthermore, in the above embodiment, the tipping of the pair of rings 3 is restricted by one tipping prevention part 14, but this is not limiting, and it is also possible to provide separate tipping prevention parts, one of which contacts one ring 3 from the inside in the long side direction, and the other of which contacts the other ring 3 from the inside in the long side direction. Furthermore, if not particularly necessary, the tipping prevention part 14 may be omitted.

[0035] The number of rings 3 is not limited to the above, and may be, for example, three or more.

[0036] Furthermore, the flashcard book according to the present invention is not limited to being a vocabulary book for memorizing words, but can also be used as a flashcard book for memorizing things other than words (such as capitals of countries). [Explanation of symbols]
