Embodiment 1

[0021] Embodiment 1: The structure of the wireless input pen is as attached figure 1 As shown, it shows the main installation and connection relationship of each component. Among them: 1-pen tip; 2-pressure sensor can use a reed contact micro switch, the pen tip can move appropriately in the axial direction, and stand on the end of the movable contact of the micro switch, and the micro switch is usually under the action of the spring force of the reed In the disconnected state, the action stroke and elastic force of the switch should be as small as possible, so as to adapt to the feeling habit of writing when writing by hand. In this embodiment, the nib pressure sensor is simply composed of the above two parts; 3-wireless input pen shell; 4- Schematic diagram of the optical motion sensor. The ready-made product can be the ADNS-2620 optical mouse sensor from Aglent Technologies in the United States, which includes an image acquisition system (IAS), a digital signal processor (D...

Embodiment 2

[0022] Embodiment 2: Since the movable nib 1 has a moving stroke when it acts on the nib pressure sensor, it may have an adverse effect on the effective induction of the mobile sensor with a small depth of field. The present invention can also adopt a sleeve structure in which the nib is fixed relative to the sensor : The nib 1 is only a protruding part of the front end of the pen shell 3, the front end of the shell with a fixed nib is equipped with an optical movement sensor 4, the inside of which is provided with a peripheral controller 9 and a circuit board 10, and 31 sets of pen bodies held by hand In the shell 3, the two can slide relative to each other in the axial direction, and the sliding range is limited by the bayonet pin 17 with a reed. The nib pressure sensor 2 is placed at the tail end of the shell 3, and a push-button power switch 14 ( See attached figure 2 ).

Embodiment 3

[0023] Embodiment 3: the shell 3 can also be used as attached image 3The shown shorter structure only houses the optical movement sensor 4 and its combination, the circuit board 10 and other devices are in the pen body 31 for holding, and the optical movement sensor chip pins are passed through flexible cables or brushes. connected to? On the circuit board 10 in the pen body 31 , the pen tip 1 is integrated with the shell 3 , and the pressure sensor 2 is fixed in the pen body 31 and mechanically connected with the tail end of the shell 3 . attached figure 2 And attached image 3 The rest of the number descriptions and appended figure 1 Similarly, after the tip of the pen touches the surface 15 of the object, the casing 3 is shrunk toward the inside of the pen body, causing the pressure sensor 2 to output a signal under pressure. Within the most effective depth of field range, it can also be adjusted at the edge of the effective depth of field range to maximize the effect...

Abstract

The invention refers to a kind of handle photoelectricity inputting pen for computer device. It sets a pressure sensor in or at side of the shell, there set light house and optical mobile sensor near the end, at the front of the mobile sensor, there sets an optical lens. The invention has a reasonable structure, it is convenient, it can input character and localize the position with handwriting mode, and it can be used in a large area, and it needn't the cable.

Description

technical field [0001] The invention relates to an input device for computer equipment, in particular to a hand-held pen-shaped positioning photoelectric input pen for computer equipment, which can be directly placed on the surface of ordinary objects (desktop, book paper or even screen surface, etc.) ) to move and locate and input the movement and status information of the pen to the computer through the wireless transmitter on the pen. Background technique [0002] The current handheld positioning input device is mainly a mechanical input pen. For example, one called "touch input pen" (96108214.3), which can change its length and diameter. The outer diameter of the stylus can be enlarged to ensure an easy grip when entering characters and graphics. The touch input pen is composed of a pen body, a pen tail handle, a grip and a head. The pen body part has a through hole extending along its axis, and the front end of the pen body part tapers. The handle of the pen tail ha...
