Problems solved by technology

[0010] In other words, if the finger sliding unit is constructed with a large width to accommodate thick fingers, when the device is used by a person with thin and narrow fingers, the positioning of the fingers in the lateral width direction relative to the finger sliding direction will be difficult. may change, thereby reducing the success rate of correct verification in one operation
This creates an unpleasant feeling: not only does the user need to place their finger on the fingerprint verification device multiple times to authenticate the fingerprint, but the person who should be recognized may not be identified

[0050] Hereinafter, a fingerprint authentication device 1A according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 6, wherein the first embodiment is taken as an example of a case where the fingerprint authentication device is arranged on an elevator. In this case, the elevator is used as an entrance of the control area or verification area, which only allows specific users to enter buildings such as apartment buildings or office buildings, and the elevator is equipped with a fingerprint verification device 1A.

[0051] As shown in FIG. 1 , the fingerprint verification device 1A is installed on a car control panel 101 in an elevator passenger car 100 . The car control panel 101 is arranged on the door frame box part (that is, the accommodating part provided for the sliding elevator door), that is to say, the control panel is arranged on the transfer side plate 103, and the user enters the passenger car After 100, when it turns ar...

[0067] A fingerprint authentication device 1B according to a second embodiment of the present invention will be described below with reference to FIGS. 7 and 8 . Those components having the same functions as those in the fingerprint authentication device 1A according to the first embodiment will be designated by the same reference numerals, and further description will be omitted.

[0068] The bottom 22a of the finger slide unit 22 of the fingerprint authentication device 1B shown in FIGS. 7 and 8 is smoothly arched and convex as it approaches the fingerprint detection portion 4 in the finger slide direction. Along with this, the side portions 22b, 22c provided with the inclined portions 22d, 22e are also curved to follow the shape of the bottom portion 22a so as to be convex in the depth direction of the finger slide unit 22, wherein the inclined The portions 22d, 22e rise obliquely at both edges of the bottom 22a in a direction of spreading away from each other. In other wo...

[0071]A fingerprint authentication device 1C according to a third embodiment of the present invention will be described below with reference to FIGS. 9 and 10 . Those components having the same functions as those in the fingerprint authentication device 1A or 1B according to the above-mentioned embodiment will be designated by the same reference numerals, and further description will be omitted.

[0072] In the fingerprint verification device 1C shown in FIG. 9 , a ground terminal 8 having a conductive member is provided on the finger sliding plate, which is located upstream of the fingerprint detection part 4 in the finger sliding direction, in other words, it is closer to the starting point. Start part 3a. As shown in FIG. 10, the ground terminal 8 is grounded by a lead wire 9 passing through the circuit board 6 provided in the circuit board accommodating portion 5b of the inner frame 5 from the rear side of the finger slide plate 3. It should be noted that, as shown in FIG...

Abstract

A fingerprint authentication device (1A) reads a fingerprint by sliding of a finger relative to a fingerprint detection section (4) that is arranged at the bottom section (22a) of a channel-shaped finger sliding unit (22). The shape of the finger sliding unit (22) is formed wider at the open top section thereof than at the bottom section (22a).

Description

technical field [0001] The present invention relates to a fingerprint verification device and an elevator using the fingerprint verification device. In the present invention, the finger slides along a groove-shaped finger sliding unit, and the fingerprint can be read by a fingerprint detection part arranged at the bottom of the finger sliding unit . Background technique [0002] In order to maintain the secrets of enterprises and institutions or protect private property, the method of setting up control areas is gradually adopted in practice. Only authorized specific personnel can enter these control areas, and each time a person enters, he must control the access to these areas. District people to verify. People have devised multiple methods for individual verification, but considering the cost factor, people widely adopt a fingerprint verification device using fingerprints. [0003] The method for reading fingerprints in the fingerprint verification device includes: [...
