[0002] Signing in refers to recording that one has attended or participated in an event. In university courses, in order to improve the teaching quality and students' enthusiasm for class, signing in is generally used to avoid students' absences. At present, it is generally done by students signing on the sign-in paper or by teachers calling the roll. The teacher calling the roll has the problem of taking up a lot of teaching time, and the signature signing method generally uses ordinary sign-in paper. Signing on a blank paper has the problem of confusing the position of the student's signature, which is inconvenient for teachers to count, and it is easy to have the phenomenon of signing on behalf of others, affecting the attendance results. The patent authorization announcement number is CN220155079U, which discloses a sign-in device. Students can complete the sign-in by pressing the signature block corresponding to their names on the sign-in device, but there will still be the phenomenon of signing on behalf of others, and it is not convenient for teachers to count absence information in time. In addition, the classrooms of university courses are not fixed. The use of the above device requires teachers or students to carry the sign-in device to the corresponding classroom for each class, which is extremely inconvenient to use; and the existing clock-in machine only has the function of simple clock-in, which cannot be combined with teaching activities and has a relatively single function.

[0015] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0016] See also Figure 1-4 , the utility model provides a technical solution of a sign-in device: Example

[0017] according to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a sign-in device includes a clock-in machine 1, a power cord 9 is provided on the side of the clock-in machine 1, a central processor 7 and a data transmission module 6 for transmitting data are provided in the clock-in machine 1, a course information library of all courses in the classroom where the clock-in machine 1 is located and a student fingerprint library of students to be in class are stored in the central processor 7, and a touch screen 5 electrically connected to the central processor 7 is provided on the clock-in machine 1. Before class, the first teacher or student to arrive at the classroom can retrieve the corresponding course information and the fingerprint of the corresponding student from the central processor 7 by operating the touch screen 5, and the name information of the students to be in the corresponding course stored in the central processor 7 is displayed on the touch screen 5. The clock-in machine 1 is provided with a fingerprint identification area 8, which includes a fingerprint sensor 82 installed in the clock-in machine 1. A finger groove 83 is provided on the surface of the clock-in machine 1, and a fingerprint collection screen 81 is embedded in the finger groove 83. The fingerprint collection screen 81 is connected to the fingerprint sensor 82. When a student signs in, the fingerprint information is collected through the fingerprint collection screen 81, and the fingerprint sensor 82 recognizes and transmits the identification information to the central processor 7. The central processor 7 analyzes and determines whether the student needs to participate in the course. If the student needs to participate in the course, the student's name information is transmitted through the data transmission module 6, and the corresponding student name on the touch screen 5 disappears.A circuit board 2 is installed in the card recorder 1, and a plurality of circuit board contact plugs 21 corresponding to the desks in the classroom are evenly distributed on the circuit board 2. A fixing plate 3 is installed in the card recorder 1. The fixing plate 3 is located on the front side of the circuit board 2, and a through hole 31 corresponding to the circuit board contact plug 21 is opened on the fixing plate 3. The card recorder 1 is provided with a plurality of key components 4, including a movable column 41 penetrating through the through hole 31 of the fixing plate. A transparent cover 43 is provided at the front end of the movable column 41, and a micro display screen 42 is installed in the transparent cover 43. The micro display screen is an LED. Display screen, a compression spring sleeved on the movable pressing column 41 is provided between the corresponding end faces of the fixing plate 3 and the micro display screen 42, an interface pin 45 is provided on the micro display screen 42, and the interface pin 45 penetrates the movable pressing column 41 and matches the contact plug of the corresponding circuit board 2. After the student's fingerprint recognition is completed, he presses down any key component 4, and the pressed key position is the seat selected by the student during class. When the key component 4 is pressed down, the interface pin 45 can be correspondingly plugged into the contact plug of the circuit board 2, so that the micro display screen 42 is connected to the micro display screen 42 through the interface pin 45. The circuit board 2 is connected. At this time, the information transmitted by the data transmission module 6 is transmitted to the micro display screen 42 through the circuit board contact plug 21 of the circuit board 2. The micro display screen 42 displays the corresponding student name. The reset member 44 formed by the compression spring can reset the key assembly 4 by pressing down. After the key assembly 4 is reset, the circuit board contact plug 21 is separated from the corresponding interface pin 45, so as to facilitate the transmission of the next signed-in student information through the circuit board 2. The name displayed on the micro display screen 42 can be displayed all the time when the card punching machine 1 is powered on. When the card punching machine 1 is powered off, the name on the micro display screen 42 disappears; if the student does not need to attend the course, the student information is not displayed on the touch screen 5, and the student cannot select a seat, which can avoid the phenomenon of going to the wrong classroom. After the student sign-in is completed, the remaining student name on the touch screen 5 is the student who has not attended the class, which is convenient for the teacher to grasp the information of the student who has not attended the class in time. Moreover, when the teacher is in class, the student name displayed on the corresponding micro display screen 42 on the card punching machine 1 is the seat of the student in class, which is convenient for the teacher to ask questions directly during the teaching process according to the name and position on the card punching machine 1, thereby improving the teaching effect. ;

[0018] In specific use, the utility model provides a sign-in device. When using the time clocking machine 1 to sign in and clock in, firstly, the time clocking machine 1 is powered on through the power cord 9, and then the student or teacher selects the information of the course to be taken on the touch screen 5. After the selection is completed, the name of the student who needs to take the course is displayed on the touch screen 5. Then the students sign in and clock in continuously on the time clocking machine 1. When clocking in, the student's fingerprint is first identified by the fingerprint identification area 8. After the fingerprint identification is completed, a button component 4 is pressed down at will. The position of the pressed button corresponds to the seat selected by the student during class. When the button component 4 is pressed down, the interface pin 45 is correspondingly plugged into the circuit board contact plug 21, and the micro display screen 42 is connected to the circuit board 2. At this time, the student name information transmitted by the data transmission module 6 is transmitted to the micro display screen 42 through the circuit board 2 and displayed. Then the next student identifies the fingerprint and selects the button whose name has not been displayed to sign in and clock in. After all students have signed in, the remaining student names on the touch screen 5 are the students who have not attended the class, and the student sign-in work before class is completed.
