Title:
情報コード読取システム
Document Type and Number:
Japanese Patent JP6593141
Kind Code:
B2
Abstract:
A system including a reader and an information terminal is provided. The information terminal displays an information code, while the reader optically reads the information code. The reader includes an emission unit and an imaging unit. The emission unit emits light in a predetermined emission state when the information code is imaged by the imaging unit. The information terminal includes an imaging unit, a control unit and a display unit. The control unit of the information terminal drives/controls the display unit to display the information code only when the predetermined emission state is imaged by the imaging unit. That is, unless the predetermined emission state of the emission unit of the reader is imaged by the imaging unit of the information terminal, the information code is not displayed on the display unit of the information terminal. Thus, security in reading the information code is further improved.
