Abstract

A tablet identification device of a tablet automatic packaging machine for recognizing information of tablets contained in tablet cassettes disclosed. The tablet device includes a plurality of RF tags and a plurality of tablet information access units. The RF tag records information of tablets contained in a corresponding tablet cassette, and attached to one side of a cassette. The tablet information access unit wirelessly receives the tablet information recorded in the RF tag and transmits the tablet information to a host computer or records new tablet information inputted from the host computer in the RF tag.

1 . A tablet identification device of a tablet automatic packaging machine comprising: 
 A) a plurality of RF tags, each of which records information of tablets contained in a corresponding tablet cassette, in which each RF tag is attached to one side of each of a plurality of tablet cassettes; and    B) a plurality of tablet information access units each of which wirelessly receives the tablet information recorded in the RF tag and transmits the tablet information to a host computer or records new tablet information inputted from the host computer in the RF tag, wherein the tablet information access unit includes:    a) an antenna for transmitting/receiving wireless signals to/from the RF tag, in which the antenna is installed facing the RF tag;    b) an RF module for modulating tablet information, which is required to be updated, to wireless signals to be outputted, and for demodulating the wireless signals received by the antenna to tablet information to be outputted;    c) a control unit for controlling transmission of tablet information required to be updated by the host computer to the RF module, and for controlling transmission of the tablet information demodulated in the RF module to the host computer; and    d) an interface unit for interfacing the control unit with the host computer.    
   
   
       2 . The device as set forth in  claim 1 , wherein the tablet information access unit further includes: 
 a tablet discharge sensor for sensing whether tablets contained in the tablet cassette are discharged or not and outputting the sensing signal to the control unit; and    a motor driving unit for driving a motor according to control of the control unit, in which the motor rotates a rotating member in the tablet cassette.
