Roller input device

A roller input device comprising:

• a substrate having a top surface, wherein the top surface is provided with a click button switch and a first tilt button switch, the click button switch has a click pressing stroke, and the first tilt button switch has a first pressing stroke;
• a bracket assembly disposed on the substrate, wherein the bracket assembly comprises a first bracket and a second bracket arranged apart from each other;
• a roller seat disposed on the substrate and between the first bracket and the second bracket, wherein the roller seat has a first end and a second end opposite to the first end, the first end is liftably and pivotally connected to the first bracket, the second end is pivotally connected to the second bracket, the click button switch is adjacent to the first end, and the roller seat selectively moves downward to a pressing position or swings to a first tilt position along a first side direction;
• and
• a stopping member connected to the roller seat, wherein the stopping member has a first stopping portion, the first stopping portion and the first tilt button switch are at one side of the roller seat, and a first initial spacing is between the first stopping portion and the top surface of the substrate;
• wherein when the roller seat is at the pressing position, the roller seat presses and triggers the click button switch, so that the first initial spacing is reduced to a first spacing, and the first spacing is less than the first pressing stroke of the first tilt button switch;
• when the roller seat is at the first tilt position, the roller seat presses and triggers the first tilt button switch, so that the first initial spacing is reduced to a second spacing, and the second spacing is less than the click pressing stroke of the click button switch.
