Bar code reader and bar code read control method

Abstract

A bar code reader has an arrangement to communicate with a host apparatus. The bar code reader includes a read unit that reads a bar code attached to an article, and outputs bar code information corresponding to the read bar code; a term information acquisition unit that acquires term information included in the bar code information; and a term expiration check unit that checks whether the term of the article has expired based on the term information. A notification unit notifies that the term of the article has expired upon determination by the term expiration check unit that the term of the article has expired.

1 . A bar code reader having an arrangement to communicate with a host apparatus in a POS system, the bar code reader comprising: 
 a read unit that reads a bar code attached to an article, and outputs bar code information corresponding to the read bar code;    a term information acquisition unit that acquires term information included in the bar code information;    a term expiration check unit that calculates whether the term of the article has expired based on the term information; and    a notification unit that notifies that the term of the article has expired upon determination by the term expiration check unit that the term of the article has expired.    
   
   
       2 . A bar code read control method applied to a bar code reader having an arrangement to communicate with a host apparatus in a POS system, the method comprising: 
 reading a bar code attached to an article, and outputting bar code information corresponding to the read bar code by using a bar code reader;    acquiring term information included in the bar code information;    calculating whether a term of the article has expired based on the term information, the calculating being performed by the bar code reader; and    notifying that the term of the article has expired upon determination that the term of the article has expired.    
   
   
       3 . A bar code reader for a POS system, the bar code reader comprising: 
 a term expiration check unit that calculates whether a term of an article has expired based on a comparison of a present time with term information; and    a notification unit that notifies a remote apparatus that the term of the article has expired.    
   
   
       4 . A bar code read control method applied to a bar code reader communicating with a remote apparatus in a POS system, the method comprising: 
 calculating whether a term of an article has expired based on a comparison of a present time with term information, the calculating being performed by the bar code reader; and notifying the remote apparatus that the term of the article has expired.
