The toner image is transferred onto the paper, and the toner image is fixed onto the recording paper and discharged.

  The reception unit 26 has a function of taking out a beacon signal by receiving and demodulating the modulated wave transmitted from the beacon signal transmitter 1 and outputting the extracted beacon signal to the control unit 27.

  The control unit 27 is connected to the operation panel 21, the document reading unit 22, the storage unit 23, the image processing unit 24, the printing unit 25, and the receiving unit 26, respectively. The control unit 27 is an information processing unit such as a microcomputer including a CPU, a ROM, a RAM, and the like. The ROM stores a control program for controlling the operation of the attendance management apparatus 2. The CPU of the control unit 27 reads out a control program stored in the ROM and develops the control program in the RAM, thereby controlling the entire apparatus. The control unit 27 functions as a reception period setting unit 41 and an attendance confirmation unit 42.

  The reception period setting unit 41 divides the lecture time for each reception period Ta and instructs the attendance confirmation unit 42 to perform a beacon signal reception operation for each reception period Ta. For example, when the lecture time is 1 hour from 9:00 to 10:00 and the reception period Ta is set to 20 minutes, the reception period setting unit 41 performs 9:00 to 9: 9 in one lecture. 20, 9:20 to 9:40 and 9:40 to 10:00 are divided into three times to instruct the beacon signal reception operation.

  The attendance confirmation unit 42 performs a beacon signal reception operation for each reception period Ta instructed by the reception period setting unit 41 to confirm attendance of the student.

Next, a beacon signal transmission operation in the beacon signal transmitter 1 will be described in detail with reference to FIG.
The beacon signal transmitter 1 performs a beacon signal transmission operation at a preset operation interval Tb. The operation interval Tb is set to a time shorter than ½ of the reception period Ta set by the reception period setting unit 41 of the attendance management apparatus 2, and is twice or more in one reception period Ta. A beacon signal transmission operation is executed. Each beacon signal transmitter 1 operates asynchronously.

  At the execution timing of the beacon signal transmission operation, the control unit 12 functions as the beacon signal generation unit 15 and generates a beacon signal including the unique ID 14 (step 101).

  Next, the control unit 12 functions as the transmission operation control unit 16 and sets 0 to the variable n (step 102). Then, the transmission operation control unit 16 determines whether another beacon signal transmitter 1 is transmitting a beacon signal based on whether or not the beacon signal is received by the transmission / reception unit 13 (step 103).

  When a beacon signal is received by the transmission / reception unit 13 in step 103 and another beacon signal transmitter 1 is transmitting a beacon signal, the transmission operation control unit 16 sets a random standby time Tc (step 104). .

  Then, the transmission operation control unit 16 waits for the elapse of the standby time Tc (step 105), returns to step 103 after the elapse of the standby time Tc, and determines whether another beacon signal transmitter 1 is transmitting a beacon signal. to decide.

  When there is no reception of the beacon signal by the transmission / reception unit 13 in step 103 and the other beacon signal transmitter 1 is not transmitting the beacon signal, the transmission operation control unit 16 uses the transmission / reception unit 13 to generate the beacon generated in step 101. A signal is transmitted (step 106).

  Next, the transmission operation control unit 16 increments the variable n (step 107), and determines whether or not the variable n has reached a preset number of transmissions N (step 108).

  If the variable n has not reached the number of transmissions N (where N is an integer equal to or greater than 2) in step 108, the transmission operation control unit 16 returns to step 104 and sets a random waiting time Tc. Thereby, even if the beacon signal is transmitted in step 106 simultaneously in the plurality of beacon signal transmitters 1 and the beacon signals collide, the next beacon signal is transmitted in the plurality of beacon signal transmitters. 1 is performed after a random waiting time Tc has elapsed. Therefore, it is possible to prevent the transmission of beacon signals by a plurality of beacon signal transmitters 1 from being repeated at the same timing.

  If the variable n reaches the number of transmissions N in step 108, the transmission operation control unit 16 ends the beacon signal transmission operation. Thereby, a beacon signal is transmitted N times in one beacon signal transmission operation executed every operation interval Tb, and even if each beacon signal transmitter 1 operates asynchronously, a beacon signal is reliably transmitted. Can do.

  The operation time Td required for one beacon signal transmission operation is set to 1/10 or less, which is sufficiently shorter than the operation interval Tb. Thereby, the transmission timing of the beacon signal from each beacon signal transmitter 1 operating asynchronously is distributed.

  Next, a beacon signal reception operation by the attendance management apparatus 2 will be described in detail with reference to FIGS. 5 and 6.

  When the set reception period Ta is reached, the reception period setting unit 41 instructs the attendance confirmation unit 42 to perform a beacon signal reception operation.

  Referring to FIG. 5, attendance confirmation unit 42 prepares for reception of a beacon signal from beacon signal transmitter 1 (step 201), and reception period setting unit 41 determines whether or not reception period Ta ends. (Step 202).

  When the beacon signal is received in step 201, the attendance confirmation unit 42 determines whether or not a beacon signal having the same unique ID 14 is received in the reception period Ta (step 203).

  If the same beacon signal is not received in step 203, the attendance confirmation unit 42 sets 1 to the variable m (step 204), and returns to steps 201 and 202.

  If the same beacon signal is received in step 203, the attendance confirmation unit 42 transmits the beacon signal having the same unique ID 14 in one beacon signal transmission operation based on the reception interval of the beacon signal having the same unique ID 14. It is determined whether or not it is a thing (step 205).

  If the beacon signal reception interval with the same unique ID 14 is within the operation time Td, it is determined in step 205 that the beacon signal is transmitted in one beacon signal transmission operation, and the attendance confirmation unit 42 returns to steps 201 and 202. .

  If the reception interval of the beacon signals with the same unique ID 14 exceeds the operation time Td, it is determined in step 205 that the beacon signal is not transmitted in one beacon signal transmission operation, and the attendance confirmation unit 42 increments the variable m. (Step 206).

  Next, the attendance confirmation unit 42 determines whether or not the variable m has reached a preset reception count M (step 207). Note that the number of receptions M is set to be equal to or greater than the number of times a beacon signal transmission operation is performed in one reception period Ta. For example, when the reception period Ta is 20 minutes and the operation interval Tb is 5 minutes, the beacon signal transmitter 1 performs a maximum of four beacon signal transmission operations in one reception period Ta. In this case, the reception count M is set to any one of 2 to 4 times.

  If the variable m has not reached the number of receptions M in step 207, the attendance confirmation unit 42 returns to steps 201 and 202.

  When the variable m reaches the number of receptions M in step 207, the attendance confirmation unit 42 identifies the student corresponding to the unique ID 14 included in the beacon signal by referring to the student information 32 (step 208).

  Then, the attendance confirmation unit 42 registers the attendance of the identified student in the attendance management information 33 (step 209), and returns to steps 201 and 202.

  When the reception period Ta ends in step 202, the reception period setting unit 41 instructs the attendance confirmation unit 42 to end the beacon signal reception operation, and the attendance confirmation unit 42 ends the beacon signal reception operation.

  FIG. 6 shows attendance management information 33 for a lecture X held from 9:00 am to 10:00 am on May 10. The attendance management information 33 is output by being displayed on the operation panel 21 or printed on recording paper by the printing unit 25. In FIG. 6, a circle signifies registration of attendance. Thereby, attendance confirmation of the student in the lecture X can be managed for each reception period Ta. For example, the attendance status of the start time and the end time can be easily grasped.

  FIG. 6 shows one-time attendance management information 33 for lecture X. When outputting, it is possible to output a plurality of lectures at once or a plurality of lectures at a time. For example, it is possible to easily grasp the attendance status for one week and the attendance status for one month.

  Also, when outputting lectures multiple times on a record sheet, the format of lecture name, students, date of attendance, etc. is printed first as an attendance management ledger, and attendance confirmation is confirmed in this attendance management ledger (○ mark, etc.) May be printed at any time. Thereby, the attendance management ledger can be easily managed by passing the attendance management ledger through the attendance management device 2 every lecture or once a day.
