An external computer 11 such as a personal computer can be connected to the reader / writer 4 at the same time, and the access information is stored as administrator data such as poisonous substances. The access information recorded in the ID card 7 or the external computer 11 leaves a history of handling poisonous substances and the like, so that if necessary, the details of the handling history can be checked.

The plurality of antennas 8, 8,... Do not necessarily need to be scanned by one reader / writer 4.
One reader / writer 4 may be used for one antenna 8, or one reader / writer 4 may be used for some of the antennae 8.
One reader / writer 4 may be used.
Further, it is not always necessary that one antenna 8 recognizes only one reagent bin 5, but a configuration in which one antenna 8 can recognize a plurality of reagent bins 5, 5,. This can be realized, for example, by using an anti-collision (signal collision prevention) function for the reader / writer 4 and the non-contact IC tag 71. If the type of drug is determined, the reader / writer 4 sequentially accesses the reader / writer 4 Access may be made in order by designating a desired drug name (or ID).

Further, the electronic weighing scale 10 is provided with an ID card insertion point 3 so that the same ID card 7 used in the storage and storage device 1 is inserted.

[0015]

Next, an example of the operation procedure of an electronic weighing scale 10 having a built-in reader / writer 4 will be described. First, the reagent bottle 5
Is placed on the electronic weighing scale 10 and at the same time, the same ID card 7 as used in the storage device 1 is taken out and inserted into the ID card insertion point 3. As a result, the electronic weighing scale 10 enters the management mode. The reader / writer 4 built in the electronic weighing scale 10 reads and displays the remaining amount of the last use from the ID tag 71 embedded in the reagent bin 5 via the antenna 41 and also displays the current actual measured value. I do. At this time, if there is a difference between the two display values, it is determined that there has been some unauthorized use or mistake, and some action is taken to notify that fact. This may be, for example, sounding an alarm, or displaying an alarm by a lamp or text.

Further, a work of recording the abnormality information is performed. This may be saved in a non-volatile memory inside the reader / writer 4, or may be recorded on the ID card 7 together with an abnormal mark. Further, it may be recorded in a nonvolatile memory or the like in an electronic circuit that controls the electronic weighing scale 10. Alternatively, when the electronic weighing scale 10 is connected to an external computer 11, data may be transferred to the computer 11 and recorded.

After removing the toxic substance or the like from the reagent bottle 5, the electronic weighing scale 10 is set in a storage mode using a button or the like, and the measured value after the weighing is measured together with the measurement date and time.
1 and the ID card 7. When an extremely small amount less than the resolution of the balance is used, the balance is naturally weighed by a higher-precision balance. In such a case, a self-report may be made using a numeric keypad.

If the electronic weighing scale 10 is connected to an external computer 11 such as a personal computer, various measurement data and access data are transferred to the external computer 11, where they are processed and stored. After all the above operations are completed,
The removed reagent bottle 5 is stored in the storage and storage device 1 for toxic substances or the like. Also at this time, if the door 21 is opened and stored by inserting the ID card 7 into the ID card insertion place 3 of the storage and storage device 1, the reagent is already specified when it is taken out. Can be checked. Thereafter, when the door 21 is closed, the electric lock 2 is automatically locked, and information indicating that the reagent bottle 5 taken out earlier is certainly stored in the original storage 1 is recorded on the ID card 7. These series of operations may be configured to be easier to use by using a button or a switch or the like added to the electronic weighing scale 10 or the storage / storage device 1 for toxic substances or the like.

The apparatus and method described above solves the administrative simplicity problem described in the prior art. However, the method and procedure described in the above embodiment need not be exactly the same, and countless variations are conceivable. For example, as described above, the ID card 7 and the non-contact ID tag 71 may be similar if they have the required functions. That is, a bar code or a magnetic card may be used as the data carrier, and a bar code reader or a magnetic card reader may be used as the reader / writer 4 corresponding to the bar code or the magnetic card so that information can be exchanged between them.

When a read-only data carrier such as a bar code or a magnetic card is used, management (user history, use history, etc.) of information read by the corresponding reader / writer 4 is stored and saved in the management device. It is necessary to be able to read out these stored information when necessary. When the memory of the ID card 7 or the non-contact ID tag 71 is small, a part or all of the data is stored in the memory in the reader / writer 4 or the external computer 11 connected thereto. And may be collectively managed. Either way, ensure that all operation history and data required for management are recorded and saved.
As a result, the manager of the toxicant or the like can always confirm the usage status of the toxicant or the like at any time.
