Abstract

The invention provides a theft surveillance case having a stationary member (100) and hook-shaped locking portions (203, 204). Two projecting portion groups (121, 122; 123, 124) are formed in the stationary member (100) with a predetermined distance between them, so that they can lock a CD accommodating case (500) either at a fixing position where the CD accommodating case is clamped by pawl portions (105, 205) or at a position where the CD accommodating case can be disconnected. The distal end portions of the hook-shaped locking portions (203, 204), which are positioned and locked at either a position where they have ridden over the outer one of the two projecting portions of the projecting portion group (121, 122; 123, 124) or a position where they have ridden over the projecting portion at the deeper side, have substantially L-shaped sections and flat portions at their top portions. The distal end portions of the hook-shaped locking portions (203, 204) have a predetermined flexibility, so that they can ride over the projecting portions.

A theft surveillance case for fixing to a merchandise accommodating case (500) having an end portion and oppositely positioned first and second side surfaces, said theft surveillance case comprising a first and a second member for clamping said merchandise accommodating case (500) (100, 200), wherein

said first member (100) has a clamp portion for clamping the first side surface of said merchandise accommodating case (500), positioning portions (102, 103) for forming surfaces against which the end portion of said merchandise accommodating case (500) is abutted and positioned, a sensitive element accommodating portion (130) capable of holding, in a storing state, a sensitive element that can be sensed by a theft surveillance unit under said positioning portions (102, 103), and a locking portion for accommodating part of said second member (200) and formed with at least two projecting portions (121, 122;
123, 124) with a predetermined gap therebetween, so as to be able to lock said second member (200) at either a first position where said merchandise accommodating case (500) is clamped and fixed or a second position where said merchandise accommodating case (500) can be disconnected, and
said second member (200) has a clamp portion for clamping the second side surface of said merchandise accommodating case (500), and at least one engaging means (203;
204) having a distal end portion disposed in said first member (100), said distal end portion locking said second member (200) at the second position, where said merchandise accommodating case (500) can be disconnected, upon being located between said two projecting portions (121, 122;
123, 124) of said locking portion, and said distal end portion being locked at the first position, where said merchandise accommodating case (500) is clamped and fixed, upon being located deeper than said two projecting portions, the second member also including jig receiving holes for providing access to the at least one engaging means:
and
wherein, a jig (310) having L-shaped projections (311, 312) must be inserted into the jig receiving holes formed in the first member and moved in a lateral direction to disengage the at least one engaging means (203, 204) from the projecting portions.
