Abstract
Abstract A self-sounding tag alarm apparatus having a tag type main body attached to a commodity and automatically operable to sound an alarm when an attempt is made to steal the commodity. The apparatus includes a coupling such as a wire, pin or the like for detachably attaching the main apparatus body to the commodity, an alarm generator mounted in the main apparatus body, a detector for detecting a signal of a particular frequency produced externally of the main apparatus body and removal of the coupling, a reset signal intake device for taking into the main apparatus body a reset signal applied externally of the main apparatus body, and an alarm control device for rendering the alarm generator operative based on a detection signal received from the detector, and rendering the alarm generator inoperative based on the reset signal received from the reset signal intake device.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
125 words
A self-sounding tag alarm apparatus for use on a commodity to prevent shoplifting, said apparatus comprising: coupling means for detachably attaching a main apparatus body to the commodity; alarm generating means mounted in said main apparatus body for generating an alarm; detecting means for detecting a signal of a particular frequency produced externally of said main apparatus body and/or removal of said coupling means; reset signal intake means for taking into said main apparatus body a reset signal applied externally of said main apparatus body; and alarm control means for rendering said alarm generating means operative based on a detection signal received from said detecting means, and rendering said alarm generating means inoperative based on said reset signal received from said reset signal intake means.
Claim 2
Dependent Claim
47 words
An apparatus as defined in claim 1, wherein said coupling means comprises a wire for connecting said main apparatus body to said commodity, said detecting means being operable to generate electrical binary conditions in response to connection and disconnection of said wire to/from said main apparatus body.
Claim 3
Dependent Claim
47 words
An apparatus as defined in claim 1, wherein said coupling means comprises a pin for connecting said main apparatus body to said commodity, said detecting means being operable to generate electrical binary conditions in response to connection and disconnection of said pin to/from said main apparatus body.
Claim 4
Dependent Claim
47 words
An apparatus as defined in claim 1, wherein said coupling means comprises a clip for connecting said main apparatus body to said commodity, said detecting means being operable to generate electrical binary conditions in response to connection and disconnection of said clip to/from said main apparatus body.
Claim 5
Dependent Claim
49 words
An apparatus as defined in claim 1, wherein said coupling means comprises an adhesive tape for connecting said main apparatus body to said commodity, said detecting means being operable to generate electrical binary conditions in response to connection and disconnection of said adhesive tape to/from said main apparatus body.
Claim 6
Dependent Claim
35 words
An apparatus as defined in claim 1, wherein said detecting means includes a resonator circuit for detecting an electromagnetic wave which is said signal of a particular frequency produced externally of said main apparatus body.
Claim 7
Dependent Claim
58 words
An apparatus as defined in claim 1, wherein said reset signal intake means includes a resonator circuit for detecting an electromagnetic wave of a predetermined frequency (reset signal) different from said signal of a particular frequency produced externally of said main apparatus body, and a comparator enabled when an output of said resonator circuit exceeds a predetermined level.
Claim 8
Dependent Claim
52 words
An apparatus as defined in claim 1, wherein said reset signal intake means includes an external terminal for taking in a signal of a predetermined voltage (reset signal) applied externally of said main apparatus body, and a comparator enabled when said signal taken in by said external terminal exceeds a predetermined level.
Claim 9
Dependent Claim
71 words
An apparatus as defined in claim 1, wherein said reset signal intake means includes an external terminal for taking in a predetermined pulse signal (reset signal) applied externally of said main apparatus body, a pulse detecting circuit for outputting a predetermined voltage upon detection of said pulse signal taken in by said external terminal, and a comparator enabled when said voltage outputted from said pulse detecting circuit exceeds a predetermined level.
Claim 10
Dependent Claim
52 words
An apparatus as defined in claim 1, wherein said reset signal intake means comprises a pair of open external terminals arranged on said main apparatus body, said open external terminals being short-circuited externally of said main apparatus body to apply a short-circuited state as a reset signal to said alarm control means.
Claim 11
Dependent Claim
31 words
An apparatus as defined in claim 1, wherein said reset signal intake means includes a magnetic sensor enabled upon detection of magnetism (reset signal) produced externally of said main apparatus body.
