Description

[Detailed explanation of the invention] This invention is based on the card learning method disclosed in Utility Application No. 55-52728, in which a large number of learning cards with questions printed with correct answers numerically are stacked and stored to perform predetermined card learning. It concerns the improvement of utensils.

In the card study device devised by the earlier application, when the front card of the study cards stacked and stored inside the box is moved slightly upwards after solving a problem, an answer is created in the form of a filled-in pattern that cannot be read as text when the cards are stored. The correct answer display for letters is partially exposed inside the small window hole of the box body, and in combination with the inner periphery of the small window hole, a white correct answer number appears, and it is possible to check whether the answer is correct or not. There is an effect that can be made interesting by looking at the correct numbers on a digital display that appears in the small window of the box.

However, this card learning device devised by the previous application has only one card located at the front among the cards stacked and stored inside the box.
Since each card must be pulled out by hand to check whether the answer is correct or not, it is troublesome to separate the cards one by one and pull them out. There was also the problem that it was difficult to match.

This invention was made with the aim of solving the problems of the earlier invention, and included a storage card push-up lever on the inner bottom of the lower end of the box that can be rotated up and down about a fulcrum on the back side of the box. When the storage card is pushed up by operating this lever, the card end protruding from the upper opening of the box body of the storage card becomes a pushed-up state in which it is tilted diagonally upward so that it is easy to pull out one card. In this state, the correct answer display for answer printing on the frontmost card is automatically aligned in the small window hole of the box body and displayed.

Hereinafter, one embodiment of this invention will be described with reference to the drawings. In the figure, 1 is a box body for storing a large number of cards A in a stacked manner, and an opening 2 for inserting and removing cards is provided at the upper end of the box body. A first window hole 3 having a substantially regular square shape and a second window hole 4 having an oblong shape are provided in the front wall of the body 1 and are displaced toward the box opening 2 and the bottom wall 5 at the lower end of the box. At the same time, above the second window hole 4, a plurality of, for example, four, small window holes 6 for answering characters are provided, which are formed at equal intervals in the lateral direction.

Each of the above-mentioned learning cards A is of a size that can be stored in the box 1 with a portion protruding from the opening 2, and the correct answer that appears in the first window hole 3 when the card is stored is displayed on its surface. Questions a1 and illustrations a4 that appear in numbers, problem-related matters a2 that appear in the small window hole 6 for answer writing when the card is stored, and questions that appear in the second window 4 when the card is stored. When the put-out card is moved upward with a predetermined stroke, a part of the card is exposed in the small window hole 6, and in combination with the inner peripheral edge 6a of the small window hole, the white correct answer number 7 is placed in the small window hole 6. Correct answer display for answer character creation a3 in the shape of an appropriate filled-in pattern that cannot be read as characters in the fully exposed state as shown in Figure 4.
are printed as shown in FIGS. 5 to 7.

In this embodiment, the card problem a1 is a history problem in which the number of years in the Gregorian calendar is answered numerically, and the problem-related items a2 are composed of period indications related to the history problem a1.

The correct answer display a3 for answer character creation is a window block filling part A when the correct answer number 7 appearing in the small window hole 6 is r600J as shown in FIG. Appearance of two O numbers The crushed parts C and C are displayed in an illegible pattern as characters arranged as shown in Figures 1 and 5, and if the correct number 7 is r1620J, 1 is displayed.
Each filled-in area for numbers, 6 numbers, 2 numbers, and 0 numbers is displayed in an illegible pattern as characters arranged as shown in Figure 6.
In the case of 1870°, there is a filled part E for the appearance of 1 number, and 8
The filled-in area G for number appearance, the filled-in area C for 7-order appearance, and the filled-in area for 0 number appearance are arranged as characters as shown in FIG. 7, and are displayed in an illegible pattern.

The study cards A are stacked and stored in the box 1 as shown in FIGS. Read and think about the answer on your own.

At this time, the correct answer display a3 for answer writing is displayed in the second window hole 4 as shown in Fig. 1, but since it has a filled pattern shape that cannot be read as a character at all, the correct answer for the problem a1 is cannot be known in advance.

Therefore, the user (lower grade students, etc.) reads the card question a1 with the cards set as shown in Figure 1, and the illustration a4 exposed in the first window hole 3 and the illustration a4 exposed in the small window hole 6 are displayed. You can also refer to problem-related matter a2 provided in the exam and study by coming up with your own answers.

After answering this answer, if the correct answer display a3 for answer printing on the storage front card A' is exposed in the small window hole 6 as shown in FIG. Since the correct number 7 appears, you can easily check whether your answer is correct by looking at the correct number 7.

After completing the learning process as described above, remove the storage front card A' from the box opening 2, insert it into the rear side of the storage card, and repeat the same method as above. All cards can be learned in sequence.

The structure and operation of the above-described card learning device are almost the same as those devised by the applicant in the earlier application, but the present invention is characterized by the following improvements to the above-mentioned card learning device. It is.

That is, a storage card push-up lever 11 is provided on the bottom wall 5 at the lower end of the box 1 and is operated to rotate up and down about a fulcrum 10 on the back side of the box. The lever push-up movement hole 12 with 11 a protruding outward is cut out at the lower position of the second window hole 4 on the front of the box, and the rotation range of the lever 11 is stored. The display a3 is characterized in that an upper limit stopper 13 for regulating the card movement stroke exposed in the small window hole 6 for answer printing is provided in a protruding manner at the lever push-up end position of the box window hole 4. The support point 1 on the back side of the box body 1 is
0 is shaped as a hole into which the hook-shaped protrusion 11b at the rear end of the lever engages.

Note that the push-up lever 11 of the storage card is connected to the bottom wall 5 of the box body.
The inner bottom plate is shaped to receive and hold the lower edge of the card as shown in FIG. 3, but this shape is not limited to the gist of this invention and can be changed as desired.

Therefore, when the card learning device devised in the earlier application is improved as described above, the card movement and the correct answer number 7 when the correct answer display a3 for answer writing is exposed in the box small window hole 6 and the correct answer number 7 is made to appear. Positioning can be easily and reliably performed by one-touch operation of the storage card push-up lever 11, and in this card push-up state, the end portion of the card that protrudes from the box opening 2 of the storage card is aligned with the imaginary line in Figure 2. As shown in the figure, since the front card is tilted obliquely, it is possible to easily separate the stored frontmost card A' from the other stacked cards and pull it out one by one.
