[0012] To better understand the technical content of the present invention, the following preferred specific embodiments are provided for illustration.

[0013] First, please refer to Figures 1 to 3 at the same time, where Figure 1 is a three-dimensional schematic view of the first embodiment of the input device of the present invention, Figure 2 is a side schematic view of the first embodiment of the input device of the present invention, Figure 3 is a front schematic view of the first embodiment of the input device of the present invention.

[0014] First, it should be noted that the present invention provides an input device 1a. A user can control a corresponding electronic device by operating the input device 1a, and the input device 1a can be set in various mouse devices or keyboard devices, etc., but the application scope of the input device 1a is not limited thereto. In the first embodiment of the present invention, the input device 1a can be used for a mouse device, which is arranged inside the mouse device and covered by a housing 3. Since the shape of the housing 3 of the mouse device is not the focus of the present invention, it will not be described in detail here. The input device 1a includes a circuit board 2, a roller 10, a support frame 20, a push switch 31, a left tilt switch 32a, and a right tilt switch 32b. The surface of the roller 10 can be made of rubber. The roller 10 has a rotation axis 11 and is pivotally connected to the support frame 20, so that the roller 10 can be toggled by the user, thereby sending a control instruction to make the electronic device execute a command. Since this technology is already well known to those skilled in the technical field to which the present invention pertains, it will not be elaborated here.

[0015] The support frame 20 is used to support the roller 10 and can be driven by the roller 10. The support frame 20 includes a body 21, a left extension arm 22a, a right extension arm 22b, a first support portion 23, and a second support portion 24a. The roller 10 is pivotally connected to the body 21 with a rotation axis 11, enabling the roller 10 to rotate relative to the body 21, and the user can drive the support frame 20 to press down and tilt towards at least one side by manipulating the roller 10. The first support portion 23 is pivotally provided at one end of the body 21, enabling the body 21 to be driven by the roller 10 to press down. The first support portion can be pivotally provided to the pivot portion 2a of the circuit board 2 by using a fixed shaft 231. The second support portion 24a is connected to the left and right sides of the body 21. The second support portion 24a is a spring that supports on the circuit board 2 and provides a restoring force when the user presses the roller 10. Thus, the first support portion 23 and the second support portion 24a support the entire support frame 20 to bear the weight of the roller 10 and the force when the user presses the roller 10.

[0016] The push switch 31 is provided on the circuit board 2 and is disposed corresponding to the body 21 below the body 21, so that when the user presses the roller 10, the body 21 is driven to press down to trigger the push switch 31 to generate corresponding control signals. And Figure 2 it can be seen that the second support portion 24a is disposed between the rotation axis 11 and the first support portion 23, the push switch 31 is disposed between the second support portion 24a and the first support portion 23, and the left extension arm 22a is also disposed between the second support portion 24a and the first support portion 23. Therefore, from the side view of the input device 1a, the positions of the above components from the front to the back are in sequence the rotation axis 11, the second support portion 24a, the push switch 31, the left extension arm 22a, and the first support portion 23, and neither the second support portion 24a nor the first support portion 23 exceeds the position where the rotation axis 11 is located.

[0017] In the first embodiment of the present invention, the input device 1a includes a left extension arm 22a, a right extension arm 22b, a left tilt switch 32a, and a right tilt switch 32b, but the present invention is not limited thereto. The input device 1a can also be provided with a single extension arm to cooperate with a single tilt switch to achieve the purpose of tilt control. The left extension arm 22a and the right extension arm 22b respectively extend obliquely downward from the left and right sides of the body 21. The left tilt switch 32a and the right tilt switch 32b are provided on the circuit board 2 and are located below the left extension arm 22a and the right extension arm 22b. Just as Figure 3As shown, the left extension arm 22a is disposed on the left side of the main body 21 and corresponds to the left tilt switch 32a, and the right extension arm 22b is disposed on the right side of the main body 21 and corresponds to the right tilt switch 32b. Thus, when the user controls the roller 10 to tilt to the left, the left extension arm 22a is driven to tilt and downwardly trigger the left tilt switch 32a. Similarly, when the user controls the roller 10 to tilt to the right, the right extension arm 22b is driven to tilt and downwardly trigger the right tilt switch 32b. With the structure of the input device 1a described above, the user does not need to apply too much force to trigger the push switch 31, the left tilt switch 32a or the right tilt switch 32b.

[0018] Next, please refer to Figure 4 a perspective view of another direction of the first embodiment of the input device of the present invention.

[0019] In the first embodiment of the present invention, the input device 1a may further include a light emitting element 41, and the light emitting element 41 may be a light emitting diode. The light emitting element 41 is disposed on the support frame 20 at a component that does not rotate or tilt with the roller 10, for example, disposed on the encoder 50 that senses the rotation state of the roller 10, but the present invention is not limited thereto. The light emitting element 41 extends into the inner side of the roller 10 to emit light of different colors or brightness according to different controls of the user, thereby increasing the aesthetics of the input device 1a, but the present invention does not limit that the light emitting element 41 can only be disposed inside the roller 10.

[0020] Finally, please refer to Figure 5 a side view of the second embodiment of the input device of the present invention.

[0021] In the second embodiment of the present invention, the push switch 31 of the input device 1b is disposed below the roller 10, and the input device 1b only has one second support portion 24b. The second support portion 24b is located directly below the main body 21 and is disposed between the push switch 31 and the first support portion 23. Therefore, from the side view of the input device 1b, the positions of the components from the front to the rear are the push switch 31, the rotation axis 11, the second support portion 24b, the left extension arm 22a and the first support portion 23 in sequence, and neither the second support portion 24b nor the first support portion 23 exceeds the position where the rotation axis 11 is located. With the structure of the input device 1b described above, the user also does not need to apply too much force to drive the main body 21 to trigger the push switch 31, the left tilt switch 32a or the right tilt switch 32b.

[0022] Thus, the input devices 1a, 1b of the present invention can allow the user to easily press or tilt the roller 10 to generate control commands to solve the defects of the prior art.
