And a tag control unit 103 that performs a predetermined operation according to a software program stored in the ROM 103a. The registration device on the management device side assigns a predetermined identification code to the tag control unit 103 through the receiving photoelectric element 101. When a command is given, the identification code is sent to the tag control unit 10.
It is configured to write data into the RAM 103b of the memory 3a.

The tag control section 103 causes the light emitting diode 104 to emit light when the identification code included in the calling signal received through the receiving photoelectric element 101 matches the identification code of the tag control section 103 itself. .

The tag device includes a photoelectric element 105 which generates an electromotive force by receiving light, and a charging element 37 such as a capacitor which is charged by a voltage generated by the electromotive force of the photoelectric element 105. Various operations of the amplifier 102 and the tag control unit 103 are performed by using the power supply 37 as a power supply.

Then, since an optical signal including the unique identification code is transmitted from the tag device 20, the process proceeds to step S13, where the optical signal is received via the identification code acquisition device 50 and transmitted to the tag device 20. An assigned unique identification code is obtained.

Next, in step S14, search management data in which the acquired unique identification code of the tag device 20 is associated with the input document name is created.

On the other hand, when the file 10 is taken out of the storage shelf 1, as shown in the flowchart of FIG. 6, it is determined in step S21 whether or not a document name relating to the file 10 to be taken out has been entered. Then, for example, when an operator who wants to take out one of the files 10 inputs the document name of the file 10, the process proceeds to step S22, where the operator corresponds to the input document name based on the search management data. The identification code is searched.

Then, in step S23, the optical signal including the retrieved calling identification code is transmitted to the portable transmitter through the stationary transmitter 64.

That is, a signal including a calling identification code is received by the infrared light receiving element 76a of the receiving unit 76 by infrared communication with the stationary transmission device 64 of the identification code managing device 60, and this signal is transmitted to the microcomputer control unit 73. , The call identification code is temporarily stored. When a calling command for a desired article is input through the input unit 75 in a state where the identification code for calling is stored in this manner, a signal including the stored identification code is converted into an infrared light signal by the light emitting element 74 for transmission. It is configured to transmit.

Next, the operation of storing the file 10 and the operation of retrieving the file 10 in the search object management system will be described.

0 and the calling identification code is
Is stored.

Next, in step T44, the take-out worker inputs the calling command while holding the portable transmitting device 70 in front of the storage shelf 1. Then, a signal including the calling identification code is transmitted from the portable transmitting device 70 to the tag device 20 of each file 10 in the storage shelf 1. Then, in step T46, each tag device 20 receives the signal including the identification code for calling, and a unique identification code matching the identification code for calling is assigned from among the tag devices 20. The tag device 20 emits light.
