DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The embodiments of a mouse with a movable signal input module of the present invention are described. Other advantages and objectives of the present invention can be easily understood by one skilled in the art from the disclosure. The present invention can be applied in different embodiments. Various modifications and variations can be made to various details in the description for different applications without departing from the scope of the present invention. The drawings of the present invention are provided only for simple illustrations, but are not drawn to scale and do not reflect the actual relative dimensions. The following embodiments are provided to describe in detail the concept of the present invention, and are not intended to limit the scope thereof in any way.
First, referring to FIG. 1 and FIG. 2, one of the embodiments of the present invention provides a mouse device with a movable signal input module, comprising: a housing 1, a control module 2, and a signal input module 3.
The housing 1 includes a base 11 and a cover 12 assembled to the base 11. The base 11 and the cover 12 together form an accommodating space 13 of the housing 1. The fore part of the cover 12 is provided with two adjacent keys 121. An opening 122 is formed between the two keys 121, and two pressing arms 1211 are respectively extended from two inner sides of the two keys 121.
The control module 2 is disposed in the accommodating space 13 of the housing 1 and can be positioned on the base 11. The control module 2 includes a main board 21 and a micro-controller 22 disposed on the main board 21. It is worth noting that the control module 2 may further include other components disposed on the main board 21.
The signal input module 3 is movably disposed in the accommodating space 13 of the housing 1 and coupled to the control module 2.
More particularly, the signal input module 3 includes a roller 31, and the roller 31 partially protrudes from the housing 1 through the opening 122.
In the present embodiment, the signal input module 3 can further include a circuit board 32 and two switches 33 disposed on the circuit board 32. The two switches 33 respectively correspond to the positions of the two pressing arms 1211 of the two keys 121. The two keys 121 can be pressed by fingers to allow the two pressing arms 1211 to press the two switches 33, thereby generating the corresponding operating signals to the control module 2.
More particularly, the roller 31 is operatively disposed on the circuit board 32 and located between the two switches 33. The roller 31 can be driven to rotate, swing left and right, or press downward relative to the circuit board 32 by a user's finger, thereby generating the corresponding operating signals to the control module 2.
More particularly, referring to FIG. 3 and FIG. 4, the circuit board 32 is movably disposed in the accommodating space 13 of the housing 1. The circuit board 32 is linearly movable relative to the housing 1 along a travelling direction D. The travelling direction D is a linear direction and can be regarded as a longitudinal direction of the housing 1. When the circuit board 32 is linearly moved relative to the housing 1 along the travelling direction D, the roller 31 is driven in sync to move linearly relative to the housing 1 along the travelling direction D. In addition, the signal input module 3 can further include a push element 34 disposed at the circuit board 32 for pushing the circuit board 32 to move, and the push element 34 can be, but is not limited to, a push button.
Therefore, if a user wishes to adjust the position of the roller 31 during operation, the user can push the push element 34 to drive the circuit board 32 to linearly move forward and backward, such that the position of the roller 31 relative to the housing 1 can be adjusted linearly. Specifically, the roller 31 shown in the FIG. 4 is located closer to the front as compared with the roller 31 shown in FIG. 3, so that the roller 31 is capable of moving forward to satisfy the needs of the user with a longer index finger. Of course, the roller 31 is capable of moving backward to satisfy the needs of the user with a shorter index finger.
More particularly, when the circuit board 32 is linearly moved relative to the housing 1 along the travelling direction D, the two switches 33 disposed on the circuit board 32 are driven to move synchronously for adjusting the positions of the two switches 33 relative to the housing 1, such that the positions of the two switches 33 relative to the two keys 121 of the housing 1 are also adjusted. Specifically, the switch 33 shown in the FIG. 4 is located closer to the front as compared with the switch 33 shown in FIG. 3, so that the switch 33 is capable of moving forward for increasing the length of the force arm under the same torque, and the user can, through the key 121, press the switch 33 with a lighter force. Of course, the switch 33 is capable of moving backward for decreasing the length of the force arm under the same torque, and the user can, through the key 121, press the switch 33 with a harder force. In this way, the user can adjust the click force when clicking the key 121.
Therefore, the signal input module 3 is linearly movable relative to the housing 1 along the travelling direction D to allow the roller 31 and the switches 33 to in sync linearly move relative to the housing 1 along the travelling direction D, for adjusting the positions of the roller 31 and the switches 33, in order to satisfy different needs.
In the present embodiment, the mouse device can further comprise a position detector 4. The position detector 4 is disposed in the accommodating space 13 of the housing 1 and coupled to the control module 2. The position detector 4 is used to detect the position of the circuit board 32 relative to the housing 1 and output a position signal to the control module 2. For example, the position detector 4 can be a hall sensor, a light blocking device, an optoelectronic sensor, or a variable resistance device. In the present embodiment, the position detector 4 is taken as a variable resistance device and will be described below in detail.
The position detector 4 is used to output a resistance value to serve as a position signal to the control module 2 according to the position of the circuit board 32 relative to the housing 1, such that the control module 2 can determine the position of the circuit board 32 relative to the housing 1 according to the position signal. By way of example, when the circuit board 32 is located at the front relative to the housing 1, the position detector 4 may output a larger resistance value. Conversely, when the circuit board 31 is located at the rear relative to the housing 1, the position detector 4 may output a smaller resistance value, and thereby the resistance value can be used as a position signal of the signal input module 3.
In more detail, if a first user has a longer index finger, so that the signal input module 3 is, for example, adjusted and located at the front relative to the housing 1, the position detector 4 outputs a resistance value of about 10 ohms. If a second user has a shorter index finger, so that the signal input module 3 is, for example, adjusted and located at the rear relative to the housing 1, the position detector 4 outputs a resistance value of about 5 ohms. Thus, the control module 2 records the position signal of the signal input module 3 according to the size of resistance value when the first user or the second user operates the mouse device. The control module 2 can have a storage element (not shown) used for storing the position signal of the signal input module 3 when either a first user or a second user operates the mouse device.
In the present embodiment, the control module 2 can further include a setting interface 23. The setting interface 23 is disposed on the main board 21 and operatively coupled to the micro-controller 22. The setting interface 23 is used to generate a setting signal to the micro-controller 22, such that the micro-controller 22 can control the position detector 4 to record the position signal according to the setting signal. The setting interface 23 can have a first setting key 231 and a second setting key 232. When the first user operates the mouse device the first time, the first user adjusts for a most suitable position of operation by means of the signal input module 3. Next, the first user presses the first setting key 231, so as to record the position signal of the signal input module 3 when operating the mouse device. Therefore, when the first user operates the mouse device again, the first user again presses the first setting key 231, and the signal input module 3 can be automatically adjusted to the most suitable position which has been previously set. Likewise, the first setting key 231 and the second setting key 232 can record respectively the position signal of the signal input module 3 when the first user and the second user operate the mouse device, thereby automatically performing the adjustment.
In another embodiment, as shown in FIG. 5, the mouse device can further comprise a display module 5. The display module 5 is disposed in and partially exposed from the housing 1, and the display module 5 is operatively coupled to the control module 2. The display module 5 can be, but is not limited to, a liquid crystal display, an indicator, or a seven-segment display. In the present embodiment, the display module 5 is, for example, a liquid crystal display. The display module 5 is used to display the position signal indicative of a current position of the signal input module 3 when a user operates the mouse device, thereby informing the user.
In conclusion, the present invention provides a mouse device with a movable signal input module, in which the roller 31 can be linearly moved, for linearly adjusting the position of the roller 31, due to the design of the signal input module 3 including a roller 31 partially protruding from the housing 1 and being linearly movable relative to the housing 1 along a travelling direction D to allow the roller 31 to synchronously move forward and backward along the travelling direction D. Moreover, the roller 31 and the switches 33 can be moved in sync, for linearly adjusting the positions of the roller 31 and the switches 33, due to the design of the roller 31 and the switches 33 being disposed on the circuit board 32, and the circuit board 32 being linearly movable relative to the housing 1 along a travelling direction D to allow the roller 31 and the switches 33 to move in sync relative to the housing 1 along the travelling direction D.
