Embodiment Construction

[0022] The drawings are not drawn to scale and certain dimensions, such as those in the thickness direction, are exaggerated for clarity. In the respective drawings, corresponding areas or parts are denoted by the same reference numerals whenever possible.

[0023] figure 1 is a schematic perspective view of the first embodiment of the optoelectronic input device according to the present invention, figure 2 is a schematic cross-sectional view taken along line II-II. because figure 2 The cross-sectional view of is circularly symmetric, so only half of it is shown. The input device 10 of this embodiment comprises a module 11 with a carrier board 4 , in this case a PCB (Printed Circuit Board) 4 . The laser 1 and the photodiode 3 are installed on the wiring pattern, and the wiring pattern is arranged on the carrier board 4 . For the upper connection of the laser 1 and the photodiode 3 a wire connection 20 is used. Located on one side of the laser 1 and the photodiode 3 is ...

Abstract

The invention relates to an opto-electronic input device (10), wherein the input is formed by detected movements of an object (M), which opto-electronic input device is provided with an optical module (11) comprising at least one laser (1) mounted on a carrier plate (4), which laser emits a radiation beam (S) that is guided to a plate (V) close to the object (M) and, after reflection therefrom, causes a change in the resonant cavity of the laser (1) which is representative of the movement of the object (M), and which is measured within the module (11). According to the invention, the plate (V) close to the object (M) comprises, within a projection of the object (M), a first portion (VI) through which the beam (S) can pass and which has a fixed position with respect to the carrier plate (4), and a second portion (V2) which is movable in a direction perpendicular to the carrier plate (4) and which comprises signal means which, when they are moved, provide a signal that is observable by a user of the device (10). In this way, the device (10) provides feedback to a human user through his tactile sense and preferably also through his auditory sense. The invention also comprises a method of manufacturing such a device and a method of inputting the movement of an object (M) using such a device.

Description

technical field [0001] The invention relates to an optoelectronic input device, wherein the input is formed by the movement of a detected object, the input device is provided with an optical module, the optical module includes: at least one laser with a resonant cavity for generating a measuring radiation beam; Optical means directed to the plate close to the target, and conversion means for converting radiation from the measuring radiation beam reflected by the target into electrical signals, wherein the conversion means consist of the resonator of the laser and the measurement of the change in the resonator during operation The measurement device is combined. The change of the resonant cavity is caused by the interference of the reflected radiation from the measuring radiation beam passing through the resonant cavity and the standing wave in the resonant cavity. The change of the resonant cavity represents the relative movement of the target relative to the module, where The...
