PURPOSE: An alarm generation unit for a goods storage box is provided to generate an alarm by mutual contact point short circuit operation of a second sensing switch and first sensing switch, thereby rapidly preventing a burglary of stored goods. CONSTITUTION: A first sensing switch(20) is electrically connected to an external alarm buzzer. The first sensing switch is attached in the inside of a main body(10). The first sensing switch generates an alarm signal according to an on/off signal. An operation body(30) is touched with the first sensing switch and short-circuits a contact point of the first sensing switch according to an opening state of a door(15). A second sensing switch(40) is touched with the operation body from the opened inner side of the main body and transfers the alarm signal according to the opening state of the door. |
