Joystick module

A joystick module, comprising:

• a casing;
• a reflective component disposed inside or outside the casing;
• a circuit board;
• a base disposed within the casing;
• a swing arm disposed within the casing, pivotally connected to the base and connected to the reflective component for driving the reflective component to move;
• a joystick connected to the swing arm for driving the swing arm to move;
• a light-emitting unit disposed on the circuit board, disposed opposite to the reflective component and configured to output an emission signal to the reflective component;
• and
• a light-receiving unit disposed on the circuit board, disposed opposite to the reflective component and configured to receive a reflected signal of the transmitted signal which is reflected from the reflective component.

A joystick module, comprising:

• a casing;
• a signal generator disposed outside the casing and configured to generate an emission signal;
• a base;
• a circuit board disposed on the base;
• a signal sensor disposed on the circuit board, disposed opposite to the signal generator and configured to sense the emission signal;
• a swing arm disposed within the casing and directly connected to the signal generator;
• and
• a joystick connected to the swing arm for driving the swing arm to move.
