The replacement page is configured to receive the fingerprint light signal of the fingerprint acquisition auxiliary device and convert it into an electrical signal, and compare the fingerprint data stored in the memory of the portable electronic device in advance, thereby implementing fingerprint identification. When the fingerprint recognition function is not used, the fingerprint acquisition assisting device can be rotated to expose the lens of the digital camera module, thereby realizing long-distance photography under normal conditions. [0007] Compared with the prior art, the fingerprint identification device has The simple structure can increase the utilization of the structure of the portable electronic device itself, and can also reduce the cost advantage. [Embodiment] The present invention will be further described in detail below with reference to the accompanying drawings. [0009] Referring to FIG. 1 and FIG. 2, a fingerprint identification device 100' includes a fingerprint acquisition assisting device 10 and a digital camera module 20, wherein the fingerprint obtaining assisting device 10 is composed of a light source 11 and a The light guide plate 12 and the hinge mechanism 13 are configured. The hinge mechanism 13, the light source 11 and the light guide plate 12 are integrally formed, and the fingerprint acquisition assisting device 10 is attached to the spindle mechanism 13, and is rotatable as the spindle mechanism 13 rotates. In addition, the fingerprint acquisition assisting device 10 further includes a casing 14 for protecting the fingerprint acquisition assisting device, which encloses a portion of the light source 11 and the light guide plate 12. [0010] The digital camera module 20 is composed of a plurality of lenses 21, a lens barrel 22, a lens holder 23, a glass plate 24, an image sensor 25, and a printed circuit board (PCB) 26. A plurality of lenses 21 are attached to the lens barrel 22, which constitute an optical lens module of the digital camera module. The lens barrel 22 is fixed in the lens holder 23, and the glass plate 24 is mounted behind the lens barrel 22, and is embedded in the inner circumferential surface of the lens 23 for protecting the image sensor 25' for the image sensor 25 for external use. Optical Image Letter 0%11259+Single Number A〇101 Page 7/Total 20 Page 1013290374-0 [0011] From July 2011, the '30th nuclear replacement page number was converted into an electronic image signal' and passed through the printed circuit board 26. The control circuit is used to transmit the signal. Light source 11 can be an LED light source or other illumination source. The light guide plate 12 further includes a fingerprint identification area 12a and a non-fingerprint identification area 12b. The two areas are adjacent to each other. The boundary between the two areas is divided by the protective fingerprint acquisition assisting device casing 14. The non-fingerprint identification area 12b is wrapped in the outer casing 14. The portion of the light guide plate not covered by the outer casing 14 is a fingerprint identification area 12a' having a fingerprint contact surface 12c and a bottom surface opposite thereto. The lower surface of the non-fingerprinting area 12b of the light guide plate has a grating 15 for causing the light source 16 to be coupled into the light guide plate 12 to be reflected at a large angle, thereby causing the light 16 to be totally reflected in the light guide plate 12, and the grating 15 It can be a periodic structure of a mountain shape plus a highly reflective coating layer (Al, Ag coating or a multi-layer high-reflection mineral film). The reflection line of the light 16 in the light guide plate is as shown in FIG. It can be seen that most of the light 16 is reflected by the grating and reflected to the fingerprint contact surface 12c. At this time, the finger signal is placed on the fingerprint contact surface 12c, and the fingerprint signal can be collected. In addition, in order to prevent light from penetrating from the side surface 12d of the light guide plate, a light absorbing film 19 may be plated on the side surface i2d. » [0012] The bottom surface opposite to the fingerprint contact surface 12c of the light guide plate 12 has an aspherical curved surface 17 'It can cooperate with the optical lens module of the digital camera module 2' to image the fingerprint image onto the image sensor 25. Since the material of the light guide plate 12 and the material of the aspherical curved surface 17 can be the same material, such as PMMA (p〇lymethyl methacrylate), PC (p〇lycarbonate, polycarbonate), etc., the light guide plate 12 And the aspherical surface 17 below it can be integrally molded by injection molding. Of course, they can also be separated and glued by means of dispensing. 09611259^Single number A0101 Page 8 of 20 1013290374-0 1380220 From July 30th, 30th, the nuclear power is coming. [0013] In order to keep the distance between the aspherical curved surface 17 and the digital camera module 2〇, the protrusions 18 of the fixed size are fixed on the bottom surface of the optical plate 12 opposite to the fingerprint contact surface 12c, and they are fixed. On the bottom surface, and the upper 18 is pressed against the upper end of the lens barrel 22, the distance between the aspherical surface 17 and the digital camera module 20 can be kept fixed, even if the aspheric surface 17 and the digital camera module are optically fixed. The distance between the lens modules remains fixed, making the imaging quality more stable. [0014] In addition, in order to tightly combine the lens barrel 22 and the protrusion 18, a pair of springs 27 may be disposed at the lower end of the digital camera module 20, and the spring 27 may be used to mount the optical lens module of the digital camera module 20. The aspherical curved surface 17 of the light guide plate and the optical lens module are kept at a fixed distance by pressing. Thus, when fingerprinting is performed, the digital camera module 2 can naturally be spaced apart from the aspherical surface 17 of the light guide plate j2. [0015] The hinge mechanism 13 protrudes from the outer casing 14 of the fingerprint acquisition assisting device 1 and is connectable to the portable electronic split 3〇. It can also be seen that the fingerprint acquisition assisting device 10 is fixed to the portable electronic device 30 via the spindle mechanism 13. By rotating the spindle mechanism 13, the fingerprint acquisition assisting device 10 can be rotated to a direction away from the digital camera module 20. The housing of the portable electronic device 30 has a recess (not shown) for stopping the spindle mechanism 13 after being rotated to a certain angle. [0016] The portable electronic device 3 can be a portable electronic device such as a mobile phone, a personal digital assistant, or a Notebook 'digital camera. When it has a digital camera module itself, the fingerprint acquisition assisting device 1 does not need to cooperate with the coffee machine to reduce the surface 1 9th page 1 〇 13290374 - 07 July 30, 101, the position of the digital camera module itself To set its specific location. [〇〇171 When using the fingerprint recognition device, the finger is placed on the fingerprint contact surface 12c, and the light rays 16 emitted by the light source 11 are refracted in the light guide plate 12, and then reflected by the grating 15 to be placed in the fingerprint contact. On the finger of face 12c. At this time, the optical system composed of the aspherical surface 17 and the optical lens module of the digital camera module 20 can image the fingerprint image onto the image sensor 25 of the digital camera module 20, and the image sensor 25 receives The optical image signal to the fingerprint image 'converts it into an electrical signal. By using the image recognition system in the digital camera module and comparing it with the pre-stored fingerprint information, fingerprint recognition can be realized. [QQ18] When the fingerprint recognition function is not used, 'only need to rotate the fingerprint acquisition assisting device 10 away from the digital camera module 20, and expose the lens of the digital camera', the camera function in general can be realized, and the camera can be photographed at a long distance. . Referring to FIG. 3 and FIG. 4, a portable electronic device 200' with a fingerprint identification device 100a according to an embodiment of the present invention includes a body 4'', a display screen 50, and a plurality of buttons 60. The digital camera module 20a of the identification device i〇〇a is mounted at one end of the body 40, wherein the lens holder 23a of the digital camera module 20a and the mobile phone body 40 are integrated, and the ridge pattern is acquired. The auxiliary device 10a is connected to the body 40 of the portable electronic device 200 via the spindle mechanism 13a. When the digital camera module 2〇a is used alone, it is a general image capturing function; when the fingerprint recognition device is used, the digital camera module 20a and the fingerprint acquisition assisting device i〇a cooperate to obtain a fingerprint image. Image is imaged on the image sensor 2 5 a, and then the image data is transferred to the relevant image recognition system, and pre-stored in the portable electric 1013290374-0 09611259 ^ ^ A 〇 101 page 10 / 20 pages 1380220 101 years .07月·30日修正_^Page· + The fingerprint information of the storage mechanism of the device 2DG is compared, so that fingerprint recognition can be realized. Compared with the prior art, the fingerprint identification device has the advantages of simple structure, increased utilization of the structure of the portable electronic device itself, and cost reduction.
