Pen type input device capable of multi-angle operation

The present invention relates to a pen type input device, and more particularly to a pen type input device capable of supporting multi-angle operation without a adjustment mechanism.

According to the mouse, the tablet, the trackball, etc., different forms of computer input devices are used to connect with the computer to perform input actions. The foregoing devices are all generalized input devices, but each has a specific spatial type in form. Taking a mouse as an example, the mouse in general impressions is in contact with a plane with a large area whether it is wired or wireless. And slip on this plane. However, recently, the aforementioned mouse has undergone considerable changes in form, which is no longer a form that must slide on a plane with a large area, but is similar to a pen type, such as the new patent right in China. As shown in FIG. 8 and FIG. 9 , the M383776 "mouse pen structure" is mainly provided with a touch device 81 and a control circuit in an accommodation space 801 and a track groove 802 inside the tube 80. 82 and a battery module 83 for supplying the operating power of the aforementioned components. The touch device 81 includes a touch switch 811 and upper and lower keys 812 and 813. The touch switches 811 and the upper and lower keys 812 and 813 are respectively disposed on the wall of the pen tube 80, wherein the touch switch 811 is provided. The left mouse button function of the conventional mouse; the control circuit 82 includes a microprocessor circuit board 821 and a detecting module 822. The detecting module 822 is an optical module that can be emitted toward the opening 803 at the front end of the pen tube 80. Light is received through the opening 803 to generate a moving trajectory that is processed via the microprocessor circuit board 821 and wirelessly transmitted to the computer.

As shown in the foregoing and shown in FIG. 9, the mouse pen sends and receives light to the opening 801 by the detecting module 822 provided in the pen tube 80.

When the opening 803 moves up and down, the cursor is moved on the Y-axis. However, since the pen tube 80 is in the shape of a round rod, it is easy to change the radial angle of the pen tube 80 when the user grips, thereby shifting the specified angle at which the detecting module 822 can work normally. In this case, when using When the front end opening 803 of the pen tube 80 moves left and right, in addition to the X-axis data, the Y-axis data is generated. Similarly, if the user moves the front end of the body up and down, the Y-axis data will be generated. The X-axis data is causing operational problems.

In addition to the above-mentioned troubles caused by the user changing the angle of the pen tube 80, the slightly larger diameter of the front end opening 803 of the pen tube 80 is also one of the reasons. Because of its large diameter, a slight movement, a considerable amount of focal length change is generated. , which in turn causes confusion or misjudgment.

Although an automatic input device has been introduced, the driver is mainly installed on the computer. Once the input device has an angular offset, the position is automatically converted to the original specified angle (0 degree) through the software. And solve the aforementioned operational troubles. However, in this way, the software must be installed in advance, and the computer resources are quite considerable. Since the input device sends the data to the computer, the X and Y axis data must be adjusted, so there will be a delay.
