Abstract: An educational toy comprises a base provided with a plurality of passages having a V-shaped cross-section, a lid having a plurality of openings corresponding to each said passage, and a series of replaceable question and answer combination cards having one opening at each question and answer illustration section. The quiz results are indicated by the rolling of at least one bead.

Abstract: An educational toy comprises a base and a statue mounted thereon. The statue has a movable head and arms. One of numerous replaceable question/answer plates is selectively placed over a quiz device which consists of an electrical conductive bottom layer, a non-conductive marking top layer, and an intermediate circuit layer sandwiched therebetween. A plurality of top opened holes are formed extending through the quiz device to said conductive bottom layer. Said plate is punched at the position corresponding to some of said holes in accordance with the question/answer combination. Two operating rods are provided for selective insertion in said holes to indicate a question and corresponding answer. If a correct answer is given, the statue will be actuated to produce an affirmative nodding and clapping action, whereas if an incorrect answer is given, the statute will render a negative wagging motion.

Abstract: An educational toy comprises in combination a base, a pair of boards and a series of replaceable quiz-and-answer plates. The base has a central spindle. The boards and one of said plates are superimposed over said base. Each board is provided with one groove which is curved in opposite directions between the two boards in such a way that a crossover is formed. A magnet is buried in said crossover. There are various well-designed representations on each plate. An indicator is displaceable over said plate to indicate whether the selected answer is correct or wrong.

Abstract: A shoe provided with a plurality of keys on the underside thereof which when depressed will produce various musical tones by means of an electronic circuit provided inside the shoe.

Abstract: An educational toy comprising a plurality of matched pairs of cartridges, each matched pair including a question cartridge displaying a question and an answer cartridge displaying the correct answer to the question, a body member having two compartments for receiving question and answer cartridges, respectively, mechanical sensing means extending to the compartments for sensing the shape of the inserted cartridges, and correct and wrong answer indicating means displaceable by the sensing means, the cartridges being configured such that a correct answer indication is only produced when a matched pair of cartridges is inserted in the said compartments.

Abstract: A case and question and answer combination cards having notches in various depths on both longitudinal sides. Question setting and answer setting plates with releasable fixing levers and an indication mechanism is provided on the case. A pair of ropes extend between the card and the question setting and answer setting plates and are connected to the indication mechanism. The ropes are pressed by the plates against both notched sides of the card to determine a correct or incorrect answer in accordance with the depth of the notches. The results are indicated by the indication mechanism.

Abstract: An educational toy comprising a case, a plurality of changeable question and answer combination cards with notched longitudinal edges, a series of question actuating means and a series of corresponding answer actuating means, an indication mechanism composed of an affirmative indicator and a negative indicator, a series of question setting plates horizontally displaceable arranged beneath the corresponding question actuating means and having at their undersides at least two ribs with different inclined bottom surfaces, a series of answer setting plates connected at the bottoms of the corresponding answer actuating means and vertically displaceable together therewith, a movable board having a series of wedge-shaped posts along one side to be in selective cooperation with one of the said inclined ribs to set the position of the board and a series of supports laterally extended away from the board, and a pair of rods transversely supported at the free ends of the said supports and each having radially extended a

Abstract: An educational toy comprising an elongated base portion, a cylinder extending longitudinally of the base portion having a plurality of protrusions around its outer periphery extending outwardly in different radial directions, a shaft retained inside said cylinder having a front end and a rear end extending from said cylinder and means permitting it to slide with respect to said cylinder and to rotate together therewith, at least one upwardly extending setting guide member on said cylinder, a first series and a second series of a plurality of push rods longitudinally spaced along said base portion having transverse lever arms extending over the said protrusions on said cylinder, each rod being surrounded by a compressible spring at a section between its lever arm and the bottom of the base portion, a changeable quiz and answer combination card having at least one setting hole for engagement with said at least one guide member for setting the card in place on the said base portion and said cylinder in a positio

Abstract: An educational toy comprises a base and a statue mounted thereon. The statue has movable head and arms. A pair of hands are relatively rotatable about a dial face of a question/answer plate. To each hand is connected a switchboard having a plurality of contacts. Contacts of one switchboard are electrically coupled to contacts of the other switchboard. A first actuating mechanism, including a first drive motor, is coupled to the head and arms of the statue. A second actuating mechanism, including a second drive motor, is connected to the head of the statue. A disc is disposed over the switchboards and includes first and second circuit systems. When the hands are positioned to indicate a question and corresponding answer, electrical contacts on the switchboards contact appropriate contacts on the disc to close the first circuit and thereby actuate the first drive motor to produce an affirmative nodding and clapping action of the statue.
