Top launching device

A top launching device for launching a top, comprising:

• a device body including first and second input rotors to rotate by rotational force, an output rotor configured to hold the top in a state with a central axis of the output rotor aligned with a central axis of the top and configured to rotate and impart the rotational force to the top, and a coupling rotor configured to transmit the rotational force from the first and second input rotors to the output rotor;
• a first operating belt configured to be inserted in the device body, and to be engaged with either the first or the second input rotor when the operating belt is in the device body;
• and
• a second operating belt configured to be inserted in the device body, and to be engaged with either the first or the second input rotor when the second operating belt is in the device body,
• the first and the second input rotors configured to rotate by a user pulling the first and second operating belts from the device body,
• the output rotor configured to rotate the top, impart the rotational force to the top, and release the top,
• the first input rotor having a first gear ratio,
• the second input rotor having a second gear ratio being different from the first gear ratio,
• the first or the second operating belt selectively employed to be selectively engaged with one of the first and second input rotors.
