Problems solved by technology

[0004] Patent CN88104538 discloses a coordinate input device for handwriting input, wherein the coordinate indicator is a stylus, which is composed of a capacitor and a coil, which can receive and transmit electric waves, and the corresponding position is induced by the coil group. At the same time, Chinese patent CN01145283 also discloses a stylus, which is also composed of magnetic elements and coils, and can measure position and pressure according to frequency changes. The above two schemes can complete handwriting input, but the device itself is an integral structure, which is not suitable for carrying and on portable devices using
[0005] The stylus used in the above two kinds of handwriting input devices has an overall structure, which is relatively large and not easy to carry or fold.

Embodiment 1

[0024] Such as figure 1 As shown, the stylus pen is composed of two parts: a penholder 1 and a movable part 2. The movable part 2 can move axially relative to the penholder 1, in a drawing structure, that is, the movable part 2 is coaxially assembled with the penholder 1, and the penholder 1 is nested in Among the moving parts 2. The movable part 2 is sleeved at the rear of the penholder 1, and the inner diameter of the assembly port of the movable part 2 and the penholder 1 and the outer diameter of the penholder 1 are transitional fit, and the clearance fit with zero clearance is optimal. The end of the barrel 1 is provided with a chuck a101 in the circumferential direction. The equivalent outer diameter of the chuck a101 (the sum of the height of the chuck a101 and the outer diameter of the barrel 1) is larger than the outer diameter of the barrel 1, and the corresponding movable part 2 The inner diameter is larger than the equivalent outer diameter of the chuck a101, the fr...

Embodiment 2

[0028] Such as image 3 As shown, in this embodiment, the movable part 2 is connected and assembled with the penholder 1 in rotation, the movable part 2 is connected with the penholder 1 through a rotating shaft 3, and the movable part 2 has a frame structure. Such as Figure 4 As shown, the movable part 2 has a slot 202 in the axial direction. The width of the slot 202 is greater than the diameter of the pen holder 1. The pen holder 1 can be folded into the slot 202 of the movable part 2 through the rotating shaft 3 to be placed, so that it can be rotated by 180 Therefore, placing the penholder 1 in the slot 202 shortens the length of the pen by nearly one-half. When the penholder 1 is opened from the slot 202, the length of the entire stylus increases, making it easier to hold.

Embodiment 3

[0030] Such as Figure 5 As shown, in this embodiment, the movable part 2 and the penholder 1 have a movable plug-in structure, the inner diameter of the movable part 2 is larger than the outer diameter of the penholder 1, and the two are in clearance fit. The movable part 2 can be directly inserted and pulled out vertically on both ends of the penholder 1, and it can be easily inserted or pulled out. It can protect the stylus pen tip when inserted. After pulling out, it can extend the length of the pen by putting it on the back end of the penholder 1. More convenient to hold and use.

[0031] The above-mentioned technical solution can make the stylus easy to carry and easy to place.

Abstract

A portable electromagnetic pen, belongs to the external device of the computer inputting field. The electromagnetic pen comprises a penholder (1) and a movable part (2) which is used for holding at least a part of the penholder (1) and can move relatively to the penholder (1). A capacitor and a coil are equipped within the penholder (1) so as to generate an electric signal in responding to the electromagnetic field formed by an electromagnetic board. The movable part (2) is pivotally connected to the penholder (1) through a pivotal annex, the internal diameter of the movable part (2) is greater than an external diameter of the penholder (1), a groove is equipped in the movable part (2), and the penholder (1) is held in the groove after pivoting on the pivotal annex. The movable part (2) can also be coaxially equipped with the penholder (1), and each end of the penholder (1) is equipped with a guide channel along which the movable part (2) can slide. The movable part (2) can also be equipped in an inserted and drawn structure with the penholder (1), and be separate from the penholder (1) to be inserted into and drawn from the two ends of the penholder (1). The electromagnetic pen can be conveniently carried and located, and be applicable to a portable handwriting input device.

Description

Technical field [0001] The invention belongs to a peripheral device in the computer input field, and is a handwriting pen applied to the external handwriting input of a computer and easy to carry. Background technique [0002] Trajectory input computer equipment is an important external computer input device, among which handwriting input is the most important and common. In addition to handwriting font input, it is also widely used in painting, art, advertising, banking and other fields and industries. [0003] The electromagnetic stylus in the stylus generally has an electromagnetic induction circuit. The signal measuring device behind the electromagnetic induction circuit and the matching handwriting board, such as an antenna board, induces and generates a changing current, so that the handwritten information is recorded. [0004] Patent CN88104538 discloses a coordinate input device for handwriting input, in which the coordinate indicator is a stylus, which is composed of a capac...
