Description

[Detailed explanation of the invention] This invention relates to a card teaching tool, in particular, the answer display part of the question card is made invisible from the outside in the initial state, the answer is exposed after a desired time has elapsed, and the response time to the question is The present invention relates to a new female card training tool that allows the user to set the following.

An embodiment of this invention will be described below with reference to the drawings.

Reference numeral 1 denotes a question card, and as shown in FIG. 6, a question display section 2 and an answer display section 3 are divided and printed on the surface thereof.

The question format and answer format of the question card are arbitrary, but one example is that question 4 and multiple answers 5 are printed on the question display section, and the correct answer number 6 among the multiple answers is printed on the answer display section. It is printed in a color such as red.

Reference numeral 10 denotes a base, and 11 denotes a question card storage section that is vertically installed on the base. The front plate 12 has a through hole 13 large enough to allow the correct answer 6 of the question card 1 to be exposed to the outside, and the left side plate 14
An insertion hole 15 into which a rotating arm operating protrusion 32 to be described later is inserted.
is drilled.

A fan-shaped cover plate 16 is rotatably attached to the back side of the front plate 12, and in the normal position, the stop piece 17 engages with the stopper piece 18, so that it just covers the through hole 13. Retained.

In the embodiment shown in the figure, the part covering the through hole 13 is made of a red filter so that the correct answer 6 of the question card 1 cannot be seen from the outside, but this cover plate is made of an opaque material. Also good.

Reference numeral 21 denotes a rotating arm rotatably disposed on the back side of the storage section 11, which includes a disk section 23 having a circumferential flange 22, and projecting pieces 24 and 25 extending outward from its eccentric position. , an oval-shaped housing section 28 that houses a weight 2T attached to the projecting piece 24, and a support piece 2 that extends forward from the left side when viewed from the back side.
9 and an actuating piece 31 extending from its tip in parallel with the accommodating part 2B and having a through hole 30 of the same shape as the through hole 13 of the accommodating part 11 at its free end. 32, a scale 33 is attached to the back surface of the disc part 23 by engraving, pasting, etc., and a gear box to be described later is installed in a bearing 34 set in the center of the disc part 23. 40 rotating shafts 4
8 is removably inserted, so that it can be rotatably pivoted.

Reference numeral 35 denotes a stopper piece for regulating the rotational position of the rotating arm 21, and a scale indicator piece 36 is disposed at the tip.

Reference numeral 40 denotes a gear box attached to the back side of the storage section 11, and as shown in FIG. A ratchet wheel 44 having, for example, six pawls connected via speed gears 42 and 43, and a rotatable pendulum 46 having a retaining portion 45 that engages with the pawls of the ratchet wheel 44 are installed inside. The tip of the pendulum 46 extends downward from the gear box 40.

The speed-increasing gear 42 is slightly movably supported in the case of the gear hook 40 by a relief hole 47, and the intermittent gear 4
1 is designed so that it does not mesh with the gear 43 when it is rotated counterclockwise when viewed from its rear side.

The shaft 48 of the intermittent gear 41 projects and extends toward the back side of the case, and the rotary arm 21 is detachably attached to this.

In this case, the positional relationship between the intermittent gear 41 and the rotating arm 21 is such that the rotating arm 21 is at a position where its operating piece 32 is located above and can be rotated counterclockwise when viewed from the front due to the weight of the weight. When this happens, the teeth of the intermittent gear 41 mesh with the gear 42 for the first time, and from this state, the actuating piece 31 of the actuating piece 32 is inserted into the insertion hole 13 of the storage portion 11 by rotating counterclockwise. The meshing state with the gear 42 is selected so that the meshing state with the gear 42 is released immediately before the gear 42 is moved.

Next, the operation of the above configuration will be explained.

First, a plurality of question cards 1 are stacked and stored in the storage section 11 with the question display section and answer display section on the front side and the correct answer display section 3 on the bottom side, and then the rotating arm 21 is placed on the scale on the back side. Turn it clockwise to the desired operating time position (Fig. 7).

In this state, the cover plate 16 of the storage 11 is not engaged with the operating piece 31 of the rotating arm 21, so the through hole is closed.
The correct answer for question card 1 is printed in the same color as the filter, so it cannot be seen from the outside.

When you release your hand from the rotating arm 21 in this state, the rotating arm 21 moves counterclockwise due to the weight of the weight.
It gradually begins to rotate at a speed determined by the child.

During this time, the learner answers the questions.

When a desired time has elapsed, the intermittent gear 41 disengages from the gear 42 and the rotating arm 21 rotates all at once, and its actuating piece 31 is inserted into the storage portion 11 and rotates the cover plate 16. Rotate clockwise.

In this state, the through hole 30 of the actuating piece portion 31 is inserted into the housing portion 11.
The correct answer 6 matches the through hole 13 and is exposed to the outside, making it possible to determine whether the learner's answer is correct or incorrect.

Thereafter, it is possible to move on to the next question by similarly rotating the rotating arm 21 to a desired position and then replacing the question cards or pulling out the first card.

As described above, according to the present invention, the answer is displayed after the set time has elapsed, so the answer time for the question can be set arbitrarily. The setting time can be lengthened and vice versa, and the setting time can be made more motivated to shorten the setting time, making it particularly suitable as a teaching tool for self-study.

In addition, in the above embodiment, since an intermittent gear is used and the rotating arm is detachably attached, the mounting positional relationship between the rotating arm and the intermittent gear is shifted by, for example, 18 (j). Since the intermittent gear is in a position where it does not mesh with the speed increasing gear, the rotating arm can rotate freely. Therefore, by attaching a weight holder etc. to the protrusion 25, it can also be used as a scale or a balance meter. It is possible.

Also, in the above embodiment, the case where gravity is used as the rotational force of the rotating arm was explained, but it is also possible to use a mainspring like a clock, or use rubber, spring, etc. as the power source. Of course, you can use it.

Furthermore, a sliding rod having a rack may be used instead of the rotating arm, and the rack may be meshed with the speed increasing gear.
