         [0043]    As shown in  FIG. 6 , when the operator uses the intermediate device  12 , if the option of emitting a single signal is selected, the intermediate device  12  will emit a single medicine location signal to the receiving device  13 . When the receiving device  13  receives the signal, not only the receiving device will generate weak warning signals, such as analog light signals or sound, as notification, but also the drawer  101  will automatically eject from the storage cabinet, allowing pharmacists to fetch the medicine more conveniently. 
         [0044]    As shown in  FIG. 7 , when the operator uses the intermediate device  12 , if the option of emitting multiple signals is selected, the intermediate device  12  will emit a plurality of medicine location signals to the receiving devices  13 . When the receiving devices  13  receive the signals, not only the receiving devices will generate weak warning signals, such as analog light signals or sound, as notification, but also the drawers  101  will automatically eject from the storage cabinet, allowing pharmacists to fetch the medicine more conveniently. 
         [0045]    Referring to  FIG. 8 , it is the schematic diagram of the embodiment of the operation of the invention. As shown in  FIG. 8 , the complete workflow of fetching the medicine of the invention is: Through the input device  11 , the medicine signals are transmitted to the intermediate device: Under the condition of being connected online, the computer  111 , having the signal transmission function via cables or the wireless method, directly transmits the medicine signals to the intermediate device  12 ; under the condition of being offline, insert the memory card  1213  containing the medicine location database into the memory card slot  1211  installed on the intermediate device  12  (or other devices that have the function of storing to or retrieving from the memory); then input the medicine information through the barcode scanner  112  or the radio frequency identification (RFID) device  113  and the medicine signals are transmitted to the intermediate device  12 . 
         [0046]    The medicine signals are converted into the medicine location signals through the intermediate device  12 ; the signals are then transmitted to the receiving devices  13 . 
         [0047]    When the receiving device  13  receives the signal transmitted by the intermediate device  12 , the receiving device will generate analog light signals or sound as notification; with the ejecting device electrically connected with the receiving device  13 , the drawer  101  can automatically eject from the storage cabinet. 
         [0048]    Referring to  FIG. 9 , it is the schematic diagram of another form of storage cabinet  100 B of the invention. According to the diagram, the storage cabinet  100  can be replaced by the storage cabinet  100 B with no drawer. The storage cabinet can be used for storing patients&#39; medical records (or other hard copy records). The medical personnel can directly input patient&#39;s information (such as name, date of birth, etc.) through the input device  11  to the intermediate device  12 ; the intermediate device  12  transmits the record location signals to the receiving device  13 ; after receiving the signals, the receiving device  13  emits analog light signals or sound, to notify the medical personnel, thus to increase the speed of locating the medical records by the medical personnel. 
         [0049]    In summary, the advantages of the fetching device for fast and accurately fetching or caching items of the invention are as follows: When the invention is applied to the medical facilities, the operator can get started immediately in different facility of pharmacy. Through the help of the input device to locate the medicine, the receiving device to notify the precise location of the prescribed medication, the operator can easily retrieve the correct medicines. Therefore, the time to retrieve the medicines and dispense the medication is shortened. The operation provides an efficient implementation. Since the receiving device can prompt with warning signals, the condition of other medicines mistakenly being retrieved can be avoided. As a result, the workflow of fetching medicines can be simplified and more effective. When the invention is applied to cache the medicines, if a medicine is to be located from the storage cabinet for caching, the medicine can be fetched easily without mistakenly being replaced with other medicines. Thus, errors can be minimized during the process when the pharmacist hands the patient with the wrong medication instead of the correct prescribed medication.
