Description

[Detailed explanation of the invention] This invention relates to a reflective projector for card learning that is used by inserting and setting a large number of learning cards one by one. With the card inserted and set so that it protrudes above the card holder and the answer display field is located within the card holder that is illuminated by the lamp, read the questions on this inserted set card, give the answer, and then turn on the lamp. The answer, which is printed on the card upside down and difficult to read before it is set, is enlarged and projected onto the screen as an erect image by the inversion and magnification effect of the convex lens, and by viewing this projected answer from the front. To provide a reflective projector for card learning, which is configured so that the correct answer to the card problem can be easily confirmed, and which has a novel configuration that does not exist in the past, and can effectively perform a prescribed card study. There is a particular thing.

The configuration of a reflective projector for card learning according to an embodiment of this invention will be described below with reference to the drawings. The main body is made of synthetic resin and has a battery box 5 integrally protruding from the right side of the rectangular frame 2, which also serves as a handle.On the rear side of the rectangular frame 2 of the main body, there is a card insertion holding part 8 (the upper side is A card receiving frame 9 is fitted and fixed, and is provided with an open U-shaped frame portion 6 and a card back pressing piece 7 protruding into the U-shaped frame portion.

Reference numeral 10 denotes a miniature light bulb that protrudes into the internal space 11 between the card receiving frame 9 and the rectangular frame 2 of the main body and is held at the end of the rectangular frame of the battery box 5. This miniature light bulb 10 is turned on when the switch 12 is turned on. It is turned on by the stored battery 13 and is arranged as shown in FIG. 1 so as to illuminate the answer display column c2 of the inserted card C diagonally from the front.

Reference numeral 15 denotes a dark box fitted to the front side of the main body rectangular frame 2 and fixed by a tensioning rubber string 16, and a projection screen 18 fixed to the front opening of the dark box 15 with a screen frame 17 is attached. is provided.

19 enlarges the answer A of the reverse print of the study card C fitted into the lens attachment opening 4 of the main body rectangular frame 2 and inserted into the card receiving frame 9 on the screen 18 as an erect image A' as shown in FIG. It is a convex lens that projects images. The large number of study cards C set and used in this reflective projector have an answer display column c2 that is inserted into the card holder 9, and a question display column c1 that protrudes above the card holder 9 when the card is inserted. Then, enter the appropriate question Q in this question display column c1.
(For example, a quiz question that asks you to answer with "false or true") is printed as shown in Figure 4 so that it can be read with the card inserted, and the answer A to this question Q is printed.
(consisting of a lie/true answer display and a picture related to this answer) is placed upside down in the answer display field c2 so that it is difficult to read before the card is inserted and set.
It is printed as shown.

Since the reflective projector for card learning of this invention has the above-mentioned configuration, the question display field c1 projects above the card receiving frame 9, and the answer display field c2 projects from the lamp. With the inserted set card C positioned in the illuminated card receiving frame 9 as shown in FIG. Answer A is printed upside down to make it difficult to read before setting it to
is the screen 18 due to the inversion and magnification effect of the convex lens 19.
Since the image is enlarged and projected as an erect image A', the correct answer to the card problem Q can be easily confirmed by viewing this projected answer from the front, which is a new configuration that has not existed before. ,
It is possible to provide a reflective projector for card learning that can effectively perform predetermined card learning.
