As described above, the link mechanism 4 has a bellows type structure in which a plurality of link arms 51 to 56 are connected by fulcrums 61 to 69, and the operation units 41 and 42 are supported by the support unit 43. The link mechanism 4 expands and contracts along the axis of symmetry A by approaching and separating from the supported fulcrum 63 as a fulcrum. Specifically, as shown in FIGS. 5 to 6, when the operation units 41 and 42 are moved closer to each other in the left-right direction, the length in the front-rear direction of the link mechanism 4 is extended. As a result, the object suction portion 44 attached to the fulcrum 69 moves forward, and the object 9 sucked by the object suction portion 44 moves forward on the upper plate 1 and the sheet 11 accordingly. As shown in FIGS. 5 to 7, when the operation units 41 and 42 are separated in the left-right direction, the length in the front-rear direction of the link mechanism 4 contracts. As a result, the object suction unit 44 attached to the fulcrum 69 moves rearward, and the object 9 sucked by the object suction unit 44 moves rearward on the upper plate 1 and the sheet 11 accordingly. Therefore, the object 9 adsorbed by the object adsorbing unit moves in the front-rear direction on the upper plate 1 and the sheet 11 by the approach and separation of the operation units 41 and 42.

Specifically, as shown in FIGS. 5 to 8, when the operation units 41 and 42 are rotated clockwise with the fulcrum 63 as a fulcrum, the object adsorption unit 44 attached to the fulcrum 69 is clockwise. The object 9 adsorbed by the object adsorbing unit 44 is rotated clockwise on the upper plate 1 and the sheet 11 accordingly. Similarly, when the operation units 41 and 42 are rotated clockwise with the link mechanism 4 extended, as shown in FIGS. 6 to 9, the object adsorption unit 44 is rotated clockwise. The object 9 adsorbed by the object adsorbing unit 44 rotates in the clockwise direction on the upper plate 1 and the sheet 11 accordingly. Further, as shown in FIGS. 5 to 10, when the operation units 41 and 42 are rotated counterclockwise with the fulcrum 63 as a fulcrum, the object adsorption unit 44 attached to the fulcrum 69 is counterclockwise. The object 9 rotated and adsorbed by the object adsorbing unit 44 is rotated counterclockwise on the upper plate 1 and the sheet 11 accordingly. Similarly, when the operation units 41 and 42 are rotated counterclockwise with the link mechanism 4 extended, as shown in FIGS. 6 to 11, the object adsorption unit 44 rotates counterclockwise. The object 9 that moves and is attracted to the object attracting portion 44 rotates in the clockwise direction on the upper plate 1 and the sheet 11 accordingly.

  As described above, the operation unit 41, 42 is moved toward, away from, and rotated from the fulcrum 63 as a fulcrum, so that the object 9 adsorbed by the object adsorbing unit 44 is moved on the upper plate 1 and the sheet 11. It can be moved freely. Since the information for moving the object 9 is described in the sheet 11, for example, as shown in FIG. 12, when the road for moving the object 9 is described in the sheet 11, the operation is performed. The person grasps the operation unit 41 with the left hand, grasps the operation unit 42 with the right hand, and moves the operation units 41 and 42 to approach, separate, and rotate with the fulcrum 63 as a fulcrum, so that the object 9 moves on the road. Training to operate to move. As shown in FIG. 13, when a maze for moving the object 9 is described on the sheet 11, the operator holds the operation unit 41 with the left hand and holds the operation unit 42 with the right hand. The operation units 41 and 42 can be trained to operate so that the object 9 moves in the maze by approaching, separating, and rotating about the fulcrum 63 as a fulcrum. As shown in FIG. 14 and FIG. 15, when a hiragana or alphabet is written as a character on the sheet 11, the operator shows a word by moving the object 9 on the hiragana or alphabet. be able to. And since the support part 43 is arrange | positioned on the symmetry axis A of the link mechanism 4, and the operation parts 41 and 42 are arrange | positioned so that it may become symmetrical with respect to the symmetry axis A, the object adsorbed by the object adsorption part 44 In order to move 9 freely, it is necessary to use the two operation parts 41 and 42 evenly.

Therefore, according to the present configuration, it is possible to provide the educational toy for operation 10 capable of performing fine operation training using both hands.

(2) Since the link mechanism 4 includes the adjustment member 45 that keeps the distance between the object suction portion 44 and the upper plate 1 within a certain range between the object suction portion 44 and the lower plate 2, the object suction portion 44. Even when the object 9 is separated from the object 9 and no longer attracts the object 9, the object attracting unit 44 can return to the state of attracting the object 9 at an early stage.

(3) Since the upper plate 1 is formed of a nonmagnetic member, the object 9 can be smoothly moved on the upper plate 1.

(4) Since the support portion 43 is arranged on the symmetry axis A of the link mechanism 4 and the operation portions 41 and 42 are arranged so as to be symmetric with respect to the symmetry axis A, the two operation portions 41 and 42 are arranged. It is possible to smoothly move the object 9 adsorbed by the object adsorbing unit 44.
