Abstract: A toy top includes a shaft portion, a body and an attacking member. The body is rotatable relative to the shaft portion in response to an impact applied to the body. The attacking member is movably connected to the body to move in a predetermined direction relative to the body between first and second positions. In the second position, the attacking member protrudes from the body a variable protruding distance which varies according to the rotating position of the body relative to the shaft portion.

Abstract: A spinning top toy includes a shaft part including a rotating shaft arranged to be in contact with a floor when spinning and a body being configured on the shaft part. The body includes a guide groove extending in a direction from the rotating shaft to an outer periphery of the body, the guide groove including a step, and a first spherical-shaped weight member being stored and movable in the guide groove.

Abstract: A spinning top launching device includes a casing; an operation member; a driving wheel being configured to be rotated around a shaft thereof as a center by operating the operation member; a holder being configured outside the casing to hold releasably a spinning top; a power transmission mechanism including a power transmission element, being connected with both the driving wheel and the holder, and being configured to transmit a rotation of the driving wheel to the holder; and a rotation direction switching member being configured to switch a rotation direction of the holder between a first direction and a second direction being opposite to the first direction by moving the power transmission element between a first revolution position and a second revolution position.

Abstract: An ophthalmic apparatus that may include a processor; and a memory storing computer-readable instructions therein, the computer-readable instructions, when executed by the processor, causing the ophthalmic apparatus to perform: acquiring a two-dimensional tomographic image of the subjected eye; calculating a preoperative shape of the subjected eye based on a preoperative two-dimensional tomographic image of a preoperative subjected eye acquired by the acquiring of the two-dimensional tomographic image; calculating a postoperative shape of the subjected eye based on a postoperative two-dimensional tomographic image of a postoperative subjected eye acquired by the acquiring of the two-dimensional tomographic image; and calculating a displacement amount between a first reference axis obtained from the preoperative two-dimensional tomographic image of the preoperative subjected eye and a second reference axis obtained from the postoperative two-dimensional tomographic image of the postoperative subjected eye, bas

Abstract: A toy top includes a shaft unit and a body into which a slot to which a fork of a launcher is to be inserted is formed concentrically with a shaft axis. The body includes a lock receiver which is disposed in an end of a slot, and which is to be locked by a locking part of the fork to be inserted into the slot. A spinning force is applied by rotation of the fork of the launcher in a state in which the fork is slid inside the slot toward the end beforehand so that the lock receiver is locked by the locking part at a previously-set locking position. Locking positions are defined respectively at opposite ends of the slot. The lock receiver is movable to and from the locking positions.

Abstract: A toy top includes a body and a shaft part. A rotating shaft of the shaft part includes plastic or metal shaft tip segments disposed at predetermined intervals in a circumferential direction of the rotating shaft. The shaft tip segment constitutes part of an outer periphery of the rotating shaft. The part of the outer periphery is configured to come into contact with the ground. Rubber is provided at the outer periphery of the rotating shaft so as to protrude outward beyond outer surfaces of the shaft tip segments. The rubber has higher frictional force than the shaft tip segments. The rubber is disposed between adjacent shaft tip segments in the circumferential direction.

Abstract: A spinner for a toy top enables a launching position of a toy top to be easily set and held in place even when a rack belt is vigorously pulled out. The spinner includes an elongated rack belt having a rack gear, and a spinner main body formed with an insertion hole through which the rack belt is inserted. The spinner main body includes a toy top mounting part rotatably provided on one surface thereof. Inside the spinner main body, a rotating mechanism that is actuated by pulling out the rack belt to impart a rotational force to the toy top mounting part is provided. The rack belt can be inserted into and pulled out from the insertion hole in a same direction as an axis of rotation of the toy top mounting part.
