Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a time clock having a function of managing entry into each room in addition to an original function of printing and storing work data (work data). .

[Conventional technology]

In a conventional time recorder, various cards such as a time card, a magnetic card, or an IC card are used as a medium for recording employment data of each person. The time and the like are printed and stored.

On the other hand, an employee ID card (ID card) that records the code of each employee is widely used for entry control into various rooms, etc., and this employee ID card is inserted into the terminal for entry and registered with the read code. Only if the code matches
The mechanism is such that the electronic lock device of the entry door is unlocked to enable entry into the room.

[Problems to be solved by the invention]

Therefore, since different cards are required for recording employment data and managing entry, there are various problems in management, cost, handling, and the like, and a time card, a magnetic card, or an IC card. Even if you insert a wrong person's card into the time clock, the employment data will be printed and stored in the wrong state even if it is mistaken, so cancellation and correction processing is very troublesome, and management work is remarkable. There was a problem that it became complicated.

Also, in the case of entry control using an employee ID card, if the code is a registered employee ID card, even if it is an employee ID of another person, it can be easily unlocked by inserting it into the terminal for entry. There was also a problem that the security purpose of entry control could not be sufficiently achieved.

Furthermore, the above entry management can be performed without a card,
As a device that can prevent unauthorized unlocking by others, a face image recognition / collation device or various entrance management devices using a fingerprint or voice recognition / collation device have already been developed. In order to accurately identify and match facial images, fingerprints, or voices, a large-scale integrated circuit (LSI) that performs enormous signal processing and hardware and software that perform various other complicated processes are required. As a result, there has been a problem that the entire apparatus becomes complicated and expensive, and it is difficult to spread the apparatus in general.

Therefore, the technical problem of the present invention is to process employment data recording and entry management together using a single employee ID card,
This simplifies the process of recording and entering a room, as well as misuse of recording employment data on another person's card or unauthorized entry into a room using another person's card to unlock the room. The problem is to ensure that the problem can be prevented with relatively simple devices.

[Means for solving the problem]

Means taken by the present invention to solve the above technical problem are as follows.

(1) A function to receive a personal code transmitted from an employee ID card must be provided.

(2) A personal file having the same code as the received personal code exists in the personal files stored in the memory, and the personal code read from the inserted time card is the same as the received personal code. Provide a function to print and write work data to the time card and the personal file in the memory when they match.

(3) When receiving the entry code from the employee ID card or the time card, after the printing and writing of the employment data are completed, the function of unlocking the lock device of the room corresponding to the entry code for a certain period of time. To have

(4) The same code as the personal code received from the employee ID card
The display lamp for determining whether the file exists in the personal file stored in the memory and the personal code read from the inserted time card match the personal code received from the employee ID card. And a display lamp for determining whether or not the lock device of the room corresponding to the entry code is unlocked.

(5) To be able to arbitrarily adjust the time during which the lock device in each room is unlocked in proportion to the distance between the time clock and each room.

Here, the employee card means an IC card having a function of storing a code (ID code) of each person and transmitting (transmitting) the code information to the time clock.

[Action]

 The above means works as follows.

The element of the above (1) specifies the personality of the employee standing in front of the time recorder by causing the time recorder to receive personal code information transmitted from the employee card by turning on a key switch provided on the employee card. To make it possible.

The element of the above (2) is used only when the same code as the personal code transmitted from the employee card is registered in the memory of the time clock and the owner of the inserted time card and the employee card are the same. The work data is printed and written to the time card and the personal file.If these are different, the work data is not printed and stored. It can be prevented.

The factor (3) is that when the printing and storage of the work data on the time card and the personal file are executed, the lock device of the room corresponding to the entry code is unlocked.
This eliminates the need to insert the employee ID card into the terminal or the like again to enter the room, simplifying the operation of entering the room. Until you find the time card and insert it into the time clock, and then print out the work data and write the personal file, you will not be able to unlock the lock. It can be prevented.

The element of the above (4) is to determine whether or not the personal code of the employee card is received, whether or not the received personal code is registered in the time clock, and the personal code of the inserted time card and the reception. In order to inform the judgment of whether or not the obtained personal codes coincide with each other and the judgment of whether or not the locking device is unlocked with the display lamps, while confirming the lighting condition of these lamps, the employment data is checked. It enables printing, storage and entry into the room to proceed smoothly.

The element of the above (5) is to increase the unlocking time of a room far from the time clock and to shorten the unlocking time of a nearby room. It is possible to solve the problem that the lock device is locked early or the lock device is kept unlocked more than necessary after entering the room.

As described above, the technical problems described above can be solved by the above means, and the problems of the conventional technology can be solved.
