New description: [New technical field] This creation is related to endoscopes, especially for an endoscope. ^ [Prior Art] The structure of the conventional endoscope is mainly provided in a main sleeve with a lens at the front end of the main sleeve, an illumination device disposed on the periphery of the lens and emitting light forward, and a rear lighting device disposed at the rear of the lens The image sensor (for example, Charge Coupled Device 'CCD), and a control circuit; the endoscope can be used to view the front surface of the lens. When the endoscope needs to be used to view the side surface of the lens side, the front end of the main sleeve is further provided with an accessory sleeve. The fitting sleeve has a side opening, and a mirror is arranged in the fitting sleeve. The mirror reflects light from the illumination device from the side opening while the pupil surface outside the side opening is reflected by the mirror to the lens. In other words, the illumination device of the conventional endoscope itself can only be illuminated forward, and the lateral illumination is achieved by the mirror. However, if the quality of the ore film of the mirror is not good or the mirror surface is stained, the light will be reflected after reflection, resulting in poor image quality of the endoscope. Therefore, the illumination device of the conventional endoscope still has its deficiencies and needs to be improved. [New content] In view of the above-mentioned shortcomings, the main purpose of this creation is to provide an illumination device for an endoscope that can supply the light source required for the forward and lateral inspection of the endoscope without specular reflection. The endoscope has a better picture quality. In order to achieve the above object, an illumination device for an endoscope provided by the present invention comprises a circuit board unit, and at least one front light-emitting member and at least one light-emitting member disposed on the circuit board unit, wherein the front light-emitting member is used for Illuminating toward the front of one of the endoscopes 'the side illuminating member is for emitting light toward one side of the endoscope. Thereby, when the endoscope is to look at the front of the lens: the front surface, the front light emitting member can be used to provide a desired light source; when the inner mirror is to view the side surface of the lens, a reflective surface is provided. When the mirror is mounted on the sleeve, the side illuminator can be used to illuminate the image capturing range of the lens through the mirror. In this way, the illumination device can supply the light source required for the endoscope, such as the side and side view, without mirror reflection, so that the endoscope can be picked up to have a better quality. The detailed construction, features, assembly or use of the illumination device for the endoscope provided in this creation will be described in the detailed description of the subsequent embodiments. However, in the field of abstraction, the knowledge of (4)f should be able to explain in detail and implement the specific examples listed in this creation, as follows: The system is used to say that the county (four), the financial_restricted patent application patent [implementation method] The following is a description of the technical content and features of the present invention by the illustrated examples.
