Abstract

A spin speed measuring device almost free of malfunction is provided at low cost. The spin speed measuring device includes a casing, a spinning body pivotally supported in the casing, a pinion gear configured to spin together with the spinning body, a belt having a rack and a plurality of indicators, the rack being configured to mesh with the pinion gear, and a detector attached to the casing to detect the indicator passing by. The spin speed measuring device measures the spin speed of the spinning body. A spin speed of the spinning body is calculated from a time period from when one of the indicators passes by to when another one of the indicators passes by, the time period being obtained using signals output from the detector.

Claims

1. A spin speed measuring device for a launcher to spin a spinning toy, the spin speed measuring device comprising:

a casing;

a spinning body pivotally supported in the casing to spin the spinning toy;

a pinion gear configured to spin together with the spinning body;

a belt having a rack and a plurality of indicators, the rack being configured to mesh with the pinion gear; and

a detector attached to the casing to detect the indicator passing by, wherein

a spin speed of the spinning body is calculated from a time period from when one of the indicators passes by to when another one of the indicators passes by, the time period being obtained using signals output from the detector.

2. The spin speed measuring device according to clam 1, wherein

the indicator is a protrusion or a notch provided on the belt, and

the detector is a contact switch activated by the protrusion or the notch.

3. The spin speed measuring device according to clam 2, wherein the protrusion or the notch is provided on either one of side faces of the belt, the side faces being faces other than a face provided with the rack.

4. The spin speed measuring device according to clam 1, wherein the spin speed of the spinning body is calculated by an external processing device connected by wire or wirelessly.

5. The spin speed measuring device according to clam 1, wherein calculation of the spin speed of the spinning body is performed by a processing device in an internal memory.

6. The spin speed measuring device according to clam 1, comprising three or more of the indicators and configured to calculate acceleration by differentiating speeds corresponding to a plurality of sections defined between the indicators.

7. The spin speed measuring device according to clam 1, wherein the spinning toy is a dummy for obtaining the spin speed of the spinning body, the spin speed being used as manipulating information to play game in video or on a network.
