Electronic article surveillance apparatus with an alarm
First Claim
1. An electronic surveillance apparatus with an alarm, comprising:
- a signal transmitter for producing a transmission signal;
a tag for generating a warning when said transmission signal from said signal transmitter is received while the tag is in a warning operation state; and
a tag controller, which is selectively coupled to said tag, for controlling the warning operation state of said tag,wherein said tag includes;
a signal receiving section, a warning generating section, a plurality of external connection terminals, a voltage dividing circuit which is connected to said plurality of external connection terminals, and a warning generation control section which is connected between said voltage dividing circuit and said warning generating section, andwherein said tag controller includes;
a plurality of external leadout terminals which are capable of being connected to said plurality of external connection terminals, and a voltage generating section for selectively supplying a high voltage exceeding a power supply voltage of said tag to said plurality of external leadout terminals.

Abstract
An electronic surveillance apparatus with an alarm, including a signal transmitter for producing a transmission signal, a tag for generating an alarm when the transmission signal from the signal transmitter is received while the tag is in a warning operation state, and a tag controller, which is selectively coupled to the tag, for controlling the warning operation state of the tag. The tag includes a signal receiving section, a warning generating section, a plurality of external connection terminals, a voltage dividing circuit which is connected to the plurality of external connection terminals, and a warning generation control section which is connected between the voltage dividing circuit and the warning generating section. The tag controller includes a plurality of external leadout terminals for connection to the external connection terminals, and a voltage generating section for selectively supplying at high voltage exceeding a power supply voltage of the tag to the plurality of external leadout terminals. The tag includes a power battery source for generating the power supply voltage which is connected to one of the external connection terminals, and the tag controller includes a battery level detection circuit which is connectable to the external leadout terminal through an external leadout terminal.
