ABSTRACT:
A timer operates when a barcode reader is lifted from a charger and a charger terminal is isolated from the charger and a communication control means transmits an application acknowledgment signal to the fixed unit via a light receiving means when a barcode indicating the ID number of a user is read within the predetermined time after operation of the timer. A check means of the fixed unit watches detection of reception of the application acknowledgment signal by a communication control means and drives an alarm means when such signal is not received within the predetermined time after the timer has operated, while lights a communicating condition display lamp of the charger for each reception of the application acknowledgment signal and each subsequent communication. Accordingly, the fixed unit can be connected easily to a host computer and can easily select its installation area, while the charger can be set to the area near a user. Communication can be confirmed from both handy unit and the charger.
