With the advancement of technology, existing reading books often combine graphics and sounds to make readers interested in reading books. For example, a CD or an MP3 player that stores a sound file. However, in this way, the user needs to search for the relevant sound file separately when reading the book, which in turn causes inconvenience in reading. Therefore, there is an optical point reading pen which utilizes optical identification technology to read optical recognition on an optical point reading point when it points to a text or image on a book. The code is then generated by a sounding device to improve the effect of reading learning.

In general, an optical point pen includes a light source and an optical sensor that provides light to a page of the book, allowing the optical sensor to sense the optical identification code on the page. Some optical point reading pens are equipped with additional functional components, such as the refill and the corresponding pen holder, so that the optical point reading pen can be used to record or track the movement track of the point pen or in addition to the point reading. Location for writing or touch.

FIG. 5 illustrates optical sensing of a sensing device according to another embodiment of the present invention. In the sensing device 200 of the present invention, the optical sensing module 210, the first pedestal 212, the first opening 212a, the second opening 212b, the optical sensor 216, the additional function module 220, and the second base The arrangement of the socket (not shown), the functional component 224, and the tubular body 226 is similar to that of the optical sensing module 110 of FIG. 1 to FIG. 4, the first pedestal 112, the first opening 112a, and the second opening. 112b, the arrangement of the optical sensor 116, the additional function module 120, the second pedestal 122, the functional element 124, and the tube 126 are arranged and operated, and will not be described herein. The difference between the sensing device 200 and the sensing device 100 is that the light exiting direction A' of the light source 214 is parallel to the surface 52 of the object 50, causing the light source 214 to emit light in a lateral manner.

It is a structure supported between the optical sensing module 210 and the surface 52. Further, in the case where the reflectance of the transparent film is high, the light source 214 is designed to emit light laterally as described above, and the light intensity of the light L is irradiated onto the surface 52 of the object 50, so that the transparent film can be prevented from being reflected. The light L' is too strong to affect the normal operation of the optical sensor 216.

In this embodiment, the structure of the first pedestal 212 at the first opening 212a extends toward the surface 52 of the object 50 as shown in FIG. 5, so that the light source 214 in the first opening 212a can be relatively adjacent to the surface of the object 50. 52, and the first pedestal 212 has a light exit port 212b at the first opening 212a, so that the light L emitted by the light source 214 can be smoothly transmitted to the surface 52 through the light exit port 212d. In other embodiments, the structure of the first pedestal 212 at the first opening 212a can be designed in other suitable shapes and sizes, which is not limited by the present invention.

In summary, in the sensing device of the present invention, the light source and the optical sensor are mounted on the first base, and the functional component is mounted on the second base, and the first base and the second base are It can be fixed or detached from each other by its first fixed structure and second fixed structure. Accordingly, the functional component and the existing light source and the optical sensor are respectively mounted on different pedestals, so that the structure of each pedestal is relatively simple to reduce the difficulty of mold opening, and when the first pedestal or the second pedestal When the design of the design is changed, it is only necessary to re-open the mold for the first base or the second base without reworking all the bases, so the rework is convenient. In addition, when the sensing device does not need to provide a corresponding function by the additional functional component, the second pedestal and the functional component mounted thereon can be directly removed from the first pedestal to effectively reduce the sense The volume of the measuring device increases the flexibility of the optical sensing module and the additional functional components. Further, the first fixing structure of the first base may be fixed to be fixed with the outer casing of the sensing device to improve the first base without installing the second base and the functional component. The versatility of the first fixed structure of the seat. In addition, the light source can be designed to laterally emit light and moderately reduce the light intensity of the optical sensing module to avoid excessive light intensity of the light source and affect the normal operation of the optical sensor.
