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 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: A toy top includes a shaft portion and a body that includes a first body part which is rotatable relative to the shaft portion in response to an impact applied to the main component and a second body part which is rotatable relative to the first body part. First spaced extensions extend radially outward from a circumference of the first body. Second spaced extensions extend radially outward from a circumference of the second body. The second extensions stepwise vary their positions relative to the first extensions when the first body part rotates relative to the shaft portion. The second extensions move into the spaces between the first extensions when the first body part rotates relative to the second body part.

Abstract: A spinning top toy includes a shaft part, a body being detachably attached to the shaft part, a locking part being configured on the body, a first locked part being configured on the shaft part, and a lock mechanism being configured either on the shaft part or the body. The body includes a movable locking part being movable between a first position and a second position. The locking part is configured to allow a relative rotation of the shaft part and the body when the movable locking part is at the first position and to block the relative rotation when the movable locking part is at the second position. The lock mechanism is configured to block a movement of the movable locking part when the movable locking part is at the first position.

Abstract: A spinning top toy includes a shaft part, and a body configured on the shaft part at a first longitudinal end thereof. The shaft part includes a shaft main body part in which an axis line corresponding to a rotation center is defined as a shaft center, and a shaft holding part holding the shaft main body part. The shaft main body includes a ground contact member configured at a second longitudinal end of the shaft part opposite to the first longitudinal end. The ground contact member has an annular-shaped ground contact part being arranged to be in contact with a contact surface and being elastically deformable. The ground contact member is rotatable with respect to the shaft holding part.

Abstract: A spinning top toy is configured to spin in a first direction, where the spinning top toy comprising includes a shaft part, a main body part, and a mounting member. The main body part is detachably configured to the shaft part. The main body is arranged to be detached from the shaft body when receiving a first amount of impact in a second direction opposite to the first direction. The mounting member is detachably configured on an outer periphery of the main body part. The mounting member is arranged to be detached from the main body when receiving an second amount of the impact in the second direction. The first amount being larger than the second amount.
