Abstract:
1. The computer mouse including an optoelectronic module, wherein the optoelectronic module includes: (a) a light source circuit; (b) at least one photoreceptor circuit configured to pick up light originating from the light source circuit directly or via reflection on an external surface, having contact pads; (c) a flexible substrate on which the photoreceptor circuit is directly mounted, wherein the substrate includes—a first portion on which the photoreceptor circuit is mounted and electrically connected, having contact pads corresponding to the contact pads of the photoreceptor circuit, —a second portion including electrical connection terminals, and—a connecting portion between the first portion and the second portion, having conductive paths, wherein the contact pads of the photoreceptor circuit are electrically connected to the corresponding contact pads of the first portion, which are connected to the electrical connection terminals of the second portion via the connection paths of the connecting portion, wherein the connecting portion allows a height and/or spacing of the second portion to be adjusted relative to the first portion, wherein the width of the connecting portion is less than half the width of one side of the first portion from which the connecting portion is connected, and the connection portion is shifted relative to the center of the side of the first portion, wherein the optoelectronic module further includes an opaque cover arranged on the first portion of the flexible substrate on a side of the photoreceptor circuit, wherein the cover includes a light passage arranged above a photosensitive area of the photoreceptor circuit and made in an external projecting part of the cover, wherein a transparent unit of complementary shape to the external surface of the cover is mounted on one part of an external surface of the cover, and wherein the transparent unit includes at least one lens arranged on the light passage above the projecting part on the photosensitive area of the photoreceptor circuit, wherein the computer mouse further includes, in a case, a mother printed circuit board at a distance from a bottom of the case, wherein the transparent lens unit of the optoelectronic module is secured to the bottom of the case above a through aperture made in the bottom of the case for the passage and reception of light, wherein an assembly formed of the cover and the first portion of the flexible substrate is secured inside the case on the transparent unit and arranged in part inside a through aperture made in the mother printed circuit board, wherein the connecting terminals of the second portion of the flexible substrate are connected to corresponding connecting pads of the mother printed circuit board next to the through aperture made in the mother printed circuit board, wherein the height and/or the spacing of the second portion is adjusted via the connecting portion, with respect to the first portion of the flexible substrate and as a function of the space between the mother printed circuit board and the bottom of the case.
