The case comprises a body 1 with a card-receiving chamber 2 and at least one cylindrical keyhole 4, each keyhole 4 being fitted wrth a locking mechanism comprising a dial-type key 5, operable to prevent the card 12 from being withdrawn. Each key 5 has a cylindrical knob 5a received in an enlarged portion 4a of the corresponding keyhole, a shank 5b and a snap member 8 disposed in a recess 7 of shank 5b and biased by a spring 10. A fixing member 11 fixedly receives the free end of the key 5. At least one circular locking hole 13 is formed in the card 12 to receive shank 56. Each hole 13 has an opening 15 so that the opening can allow the key to access to the locking hole but the card 12 can be held by rotation of the key(s). In Figure 4 the locking holes are provided by a separate member (16) mounted to the card (12). <IMAGE> |
