Game machine topper device capable of noncontact power supply, control method thereof, and game machine using same

A gaming machine comprising:

• a gaming machine body which displays game images through a body display and controls operations of a game according to a user's input to provide the game to the user;
• and
• a topper device for a gaming machine, which is coupled to an upper portion of the gaming machine body and operates by displaying content data provided from the gaming machine body,
• wherein the topper device for a gaming machine receives power wirelessly from the gaming machine body in a non-contact manner using a wireless power receiving coil unit which magnetically couples with a wireless power transmission coil unit included in the gaming machine body,
• wherein the topper device comprises a control module which sets different operation modes of the topper device corresponding to the current level of power received wirelessly from the wireless power receiving module, and controls to restrictively operate at least a portion of display elements of the topper device according to the operation modes,
• wherein the control module confirms a current level of a receiving current received wirelessly through the wireless power receiving coil unit, and
• wherein:
• when the confirmed current level is below a preset first current level, sets the operation mode to a first mode, and wherein in the first mode, the control module limits brightness of a display module within a first range, and restricts a content displayed on the display module to standby content:
• when the confirmed current level is equal to or above the preset first current level but below a second current level, which is set higher than the preset first current level, the control module sets the operation mode to a second mode, and wherein in the second mode, the control module does not limit the brightness of the display module, and does not restrict the content displayed on the display module;
• and
• when the confirmed current level exceeds the second current level, the control module sets the operation mode to a third mode, and wherein in the third mode, the control module does not limit the brightness of the display module, does not restrict the content displayed on the display module, and a light-emitting border provided at an edge of the display module performs a lighting operation.
