Description

  The present invention relates to an IC card reader having a function as a time recorder that reads identification information of an employee (worker) stored in an IC card and records the time at that time.

2. Description of the Related Art Conventionally, an IC card reader having a function as a time recorder that reads employee identification information stored in an IC card and records the time at that time is known (for example, see Patent Document 1). .
Such an IC card reader is used in a system for managing the attendance of store employees.

In such a system, employee identification information (hereinafter referred to as ID) such as an employee number is recorded on the IC card. When an employee goes to work and leaves the IC card close to the IC card reader installed in the store, the IC card reader reads the ID recorded on the IC card and records the time at that time. To do. The recorded data is transferred to the management server at the headquarters and used for employee salary calculation.
Japanese Patent Laid-Open No. 9-185740 (4th Mitigation, FIGS. 3, 4, and 5)

  Here, the above-mentioned recording work of the attendance time is a work that an employee can independently perform without monitoring and approval by the store manager who is an approver. Therefore, the employee records the attendance time earlier than the time when the work is actually started, or the work time is recorded after the time when the work is actually finished, or the IC card is stored in another IC card. It can be handed over to employees, etc., and the attendance time can be recorded instead. If such a time record is recorded, the working hours will be more than the actual working hours, so the store manager will have to pay extra wages.

  On the other hand, it is also possible for the store manager himself / herself to perform the work of recording the attendance / leaving time by bringing the IC card reader close to the target employee's IC card. In that case, fraud by the employees described above can be prevented.

  However, in that case, it becomes possible for the store manager to record the attendance time so that the employee cannot confirm whether or not his / her attendance time record has been properly recorded. For this reason, when time and attendance times are recorded, employees become uneasy because they do not know whether their time and attendance times have been recorded properly, creating distrust with the store manager, which increases work efficiency. It has the problem of being lowered.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an IC card reader that enables an employee and his employer to record the time for going and leaving while confirming each other. .

In order to achieve the above object, an IC card reader according to an aspect of the present invention includes:

The control unit may cause the display unit to display information corresponding to the instruction selected by the selection unit, together with a time counted by the current time counting unit.

  Moreover, you may provide the transmission means which transmits the time for management of the working time recorded on the said recording medium to an external device.

A sensor for detecting a tilt of a display surface of the display device;
A reading restriction unit that allows the IC card reading unit to read the IC card to be checked only when the inclination of the display surface is within a predetermined range;
May be provided.

  When reading the IC card to be checked, the IC card reader of the present invention reads only on one surface on which the IC card reader is disposed, so that the display surface is always disposed on the outside. Further, since the IC card reading unit is covered with an electromagnetic shield in the case, the IC card can be read only on one surface on which the IC card reading unit is arranged. Therefore, for example, an employee and his employer can record the time for going and leaving while confirming the time with each other.

  Hereinafter, an IC card reader according to an embodiment of the present invention will be described with reference to the drawings. Note that the IC card reader in the present embodiment functions as a time recorder that registers time.

FIG. 1 is a diagram showing an appearance of an IC card reader 1 according to an embodiment of the present invention.
FIG. 2 is a diagram showing the inside of the IC card reader 1 of FIG.
FIG. 3 is a block diagram showing a control circuit of the IC card reader 1 of FIG.
As shown in FIGS. 1 and 2, the IC card reader 1 includes a case 10, a display unit 11, an operation unit 12, a control board 13, an IC card reading unit 14, and a magnetic shield 15. ing.

  The display unit 11 is configured by a liquid crystal panel, for example, and is incorporated on the upper surface 10 a side of the case 10. The display surface of the display unit 11 is exposed from the case 10, and the current time and an instruction selected by the operation unit 12 described later are displayed on the display surface of the display unit 11.

  The operation unit 12 includes a button switch 12a and a button switch 12b. The button switch 12 a and the button switch 12 b are provided in the display unit 11 on the upper surface 10 a of the case 10. On the surface of the button switch 12a, the characters “attendance” are printed and pressed when recording the attendance time of the worker. On the surface of the button switch 12b, the characters “Leave Work” are printed and pressed when the worker leaves the office.

  The IC card reading unit 14 is located on the bottom surface 10b side of the case 10 and incorporates a coiled antenna circuit. A current having a carrier frequency of 13.56 MHz is passed through the antenna circuit, thereby generating an electromagnetic field in the vicinity of the antenna circuit. Further, the data request signal is superimposed on the carrier frequency and transmitted from the antenna circuit.

  In addition, a coiled antenna circuit is also built in the IC card to be read, and the antenna circuit is connected to an integrated circuit including a CPU, a memory in which identification information is recorded, and the like.

Therefore, when the IC card is brought close to the IC card reading unit 14, a current flows through the antenna circuit in the IC card due to electromagnetic induction, and power for driving the integrated circuit is supplied. Further, when the IC card receives the data request signal transmitted from the IC card reader 14 via the antenna circuit, the IC card reads the information recorded in the memory of the IC card, and the radio wave signal obtained by modulating the information is read from the IC card. It transmits to the reading device 1. Then, the IC card reading unit 14 receives the radio signal by the antenna circuit, demodulates it, and acquires information transmitted from the IC card.
With the above-described mechanism, the IC card reading unit 14 reads identification information (hereinafter referred to as ID) such as a worker recorded on the IC card when the IC card is brought close to the IC card.

  In the case 10, the magnetic shield 15 is disposed so as to cover the portion other than the bottom surface 10 b side of the IC card reading unit 14. The magnetic shield 15 is made of highly permeable iron or the like, and prevents the magnetic field from entering beyond the magnetic shield 15 by bypassing the magnetic field. Thereby, the bottom surface 10b side of the case 10 becomes the reading surface S, and information can be read only from the IC card in a state of facing the bottom surface 10b of the case 10.

  A control circuit for controlling the entire IC card reader 1 is formed on the control board 13. As shown in FIG. 3, the control circuit includes a ROM (Read Only Memory) 131, a RAM (Random Access Memory) 132, a timer unit 133, a recording unit 134, a communication unit 135, and a CPU (Central Processing Unit) 136. And consist of

The ROM 131 stores a program to be executed by the CPU 136 and is connected to the CPU 136.
The RAM 132 is connected to the CPU 136, and the storage area of the RAM 132 is used as a work space when the CPU 136 executes a program stored in the ROM 131.
The clock unit 133 is connected to the CPU 136 and clocks the current time.

The recording unit 134 may be configured by a non-volatile semiconductor memory such as a flash memory, or may be configured by a hard disk drive. In the recording unit 134, an identification code of the store manager and an identification code of the worker are registered in advance, and identification information read from the IC card, information indicating the time and an instruction selected by the operation unit 12 are sequentially displayed. Are recorded in association with each other.
The CPU 136 is connected to the display unit 11, the operation unit 12, and the IC card reading unit 14 and is also connected to the communication unit 135.

  The communication unit 135 has an antenna or the like different from the IC card reading unit, and transmits and receives information to and from an external device by wireless communication.

The IC card reader 1 provided with the communication unit 135 is incorporated into an attendance management system 30 as shown in FIG. 4, for example.
The attendance management system 30 shown in FIG. 4 includes IC card readers 1A to 1C disposed in stores A to C, a plurality of store terminals 31A to 31C respectively disposed in the stores A to C, and a management headquarters. The management server 33 is arranged.

  The IC card readers 1A to 1C are the same as the IC card reader 1 described above, and have the configurations shown in FIGS. In each store A to C, the IC card readers 1A to 1C and the store terminals 31A to 31C are connected by wireless LANs 32A to 32C. The plurality of store terminals 31 </ b> A to 31 </ b> C and the management server 33 are connected by a WAN (Wide Area Network) 34.

  The shop terminals 31A to 31C output information transmission commands to the CPUs 136 of the IC card readers 1A to 1C via the wireless LANs 32A to 32C. The IC card readers 1A to 1C transmit the identification information acquired from the IC card and the time information from the communication unit 135 to the store terminals 1A to 1C as attendance / leaving information. Each store terminal 31A-31C totals the attendance information in each store A, B, C, for example.

  The management server 33 outputs an information transmission command to each store terminal 31 </ b> A to 31 </ b> C via the WAN 34. In response to the information transmission command, the store terminals 31 </ b> A to 31 </ b> C transmit the result of counting the attendance / leaving information at each store or the identification information and time information acquired at each store to the management server 33.

  Next, a method for recording a worker's attendance time using the IC card reader 1 and the operation of the IC card reader 1 will be described.

  First, the store manager confirms the employee who goes to or leaves the store and selects management information from the operation unit 12. For example, the button switch 12a is pressed when the attendance time is recorded, and the button switch 12b is pressed when the leaving time is recorded. The CPU 136 displays management information (attendance or departure) corresponding to the pressed button on the display unit 11.

  Next, the store manager brings the IC card possessed by the store close to the card reading surface S of the IC card reader 1. As a result, the store manager's identification code stored in the IC card is read through the electromagnetic waves radiated from the card reading surface S. The CPU 136 causes the RAM 132 to store the current time measured by the time measuring unit 133 in association with the read store manager identification code.

  The CPU 136 confirms from the identification code registered in the recording unit 134 in advance that the identification information stored in the RAM 132 is that of the store manager. This is an identification code. The CPU 136 monitors the time measured by the timer 133, stores the store manager's identification code in the RAM 132 until the store manager's identification code is stored in the RAM 132, and the predetermined time has elapsed. In addition, the store manager identification code stored in the RAM 132 and the time stored correspondingly are deleted.

The store manager causes the worker to present the IC card owned by the worker until the predetermined time elapses after the IC card reader 1 reads his / her IC card.
When the worker presents the IC card horizontally, for example, the store manager brings the card reading surface S of the IC card reader 1 close to the IC card. Thereby, the identification code of the worker stored in the IC card is read through the electromagnetic wave radiated from the IC card reading surface S. When the IC card is read, the display unit 11 of the IC card reader 1 faces upward, so that both the worker and the store manager can check the time at that time.

  The CPU 136 confirms that the identification information read from the IC card is the identification information of the worker registered in advance in the recording unit 134 and recognizes that the store manager identification information is held in the RAM 132. If these confirmations can be made, the CPU 136 identifies the worker identification information read from the IC card, the time measured by the time measuring unit 133 at that time, and the management information selected by the operation unit 122 at that time. Are recorded in the recording unit 134 in association with each other.

  As described above, when receiving an information transmission command from the store terminal via the communication unit 135, the CPU 136 transmits the identification information, management information, and time information recorded in the recording unit 134 from the storage unit 134 according to the command. Read out and output to the store terminal of the transmission source of the information transmission command.

Next, advantages of the IC card reader 1 of this embodiment will be described.
(1) FIG. 5 schematically shows the store manager e, the employee w, the IC card reader 1 and the IC card C when the above-described work is performed.
As described above, the IC card reader 14 is covered with the magnetic shield 15 except for the card reading surface S. Therefore, information recorded on the IC card C can be read only from the IC card reading surface S. Therefore, when reading the information recorded on the IC card C, the IC card reading surface S is always brought close to the IC card C. Therefore, at that time, the display unit 11 located at the position facing the IC card reading surface S should be in a position where it is easy to enter the field of view of both the person to whom the attendance and attendance times are recorded and the store manager e and the employee w. become. Therefore, the store manager e and the employee w can record the attendance time while confirming the information regarding the record of the attendance time of the employee w displayed on the display unit 11. In other words, since the store manager cannot prevent fraud, the trust of the worker can be obtained.

  (2) Since the store manager reads the store manager's identification code from the store manager's IC card and approves the worker's attendance time using the identification code, the worker uses the IC card reader 1 without permission. If you try to memorize the time incorrectly, you can't.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation is possible. Examples of such modifications include the following.

  (A) In the above embodiment, the button switches 12a and 12b are provided and the management information as an instruction is selected. However, for example, the management information is selected according to the time counted by the time measuring unit 133. Good. For example, attendance may be selected as predetermined management information from 8:00 am to 1:00 pm, and retirement may be selected as predetermined management information from 1:00 pm to 7:00 pm.

  (B) The button switches 12a and 12b may be one button switch, and the management information may be changed each time the one button switch is pressed. Moreover, you may enable it to further select a going-out time, a return time, etc. as management information.

  (C) The approver of the working time of the worker does not need to be a store manager, and may be another manager. Furthermore, you may enable it to approve between workers.

  (D) The IC card reader 1 is provided with a tilt sensor, and the tilt sensor estimates the tilt of the display surface of the display unit 11, and when the tilt is not within a predetermined range, the information read from the IC card is recorded. It may be configured to prohibit the above. If it does in this way, unless the worker and the store manager can see the display of the display part 11 reliably, it becomes impossible to record identification information, and fraud can be prevented.

  (E) The button switches 12a and 12b may be of a touch panel type displayed on the display unit 11 and pressed.

  (F) The store manager may be able to read from the IC card later than the worker's IC card. In this case, the information read from the IC card of the worker is temporarily stored in the RAM 132 and recorded in the recording unit 134 after the reading of the store manager's IC card is completed.

It is the front view (a) and back view (b) of the IC card reader 1 which concerns on embodiment of this invention. It is the figure which represented typically the inside of the IC card reader shown in FIG. It is a block diagram which shows the control circuit of the IC card reader shown in FIG. It is a structure at the time of applying the IC card reader shown in FIG. 1 to an attendance management system.
