Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a prize winning game device, and more particularly to a prize winning game device in which a prize is grasped by operating a grasping eye.

[Technical background of the invention and its problems]

Various game devices have been devised in the past, in which the game player manipulates the fingers to win prizes, and this type of game device has a game space surrounded by a transparent board or a semicircular member. A gripper that can be opened and closed is provided so that it can be moved to any desired position and can be moved up and down. Then, the game player moves the grasping eye, and the grasping eye automatically descends to grasp a predetermined prize.

However, in the conventional device described above, the gripping eye is connected to the end of the chain, and the gripping eye is moved up and down by winding up and unwinding the chain, so the gripping eye may swing. Otherwise, there was a problem that the prize could not be grasped reliably due to rotation. This has the problem of giving the game player a sense of anxiety and causing him to lose his desire to play the game. In addition, the opening/closing operation of the gripper is such that when the gripper lowers via a link mechanism, it opens and closes as the gripper rises. It has the disadvantage that there is variation. This drawback can be overcome by using a motor, but when a motor is used, there are problems in that the weight is large and the gripping force on the prize is large and the prize may be crushed.

[Purpose of invention]

The present invention has been developed in view of the above points, and is a prize-grabbing game device that can reliably move the gripper up and down without rocking, and can also reliably open and close the gripper. The purpose is to provide the following.

[Summary of the idea]
