Abstract: Disclosed herein is an external storage device. The external storage device includes a non-volatile storage medium for storing digital data, a Universal Serial Bus (USB) port for providing an interface with an external apparatus, and an expansion slot for accommodating a conventional memory module. The external storage device provides access channels complying with USB Mass Storage Class (MSC) specifications so that the external apparatus accesses the non-volatile storage medium and the memory module, inserted into the expansion slot, through the USB port. When the external storage device receives a medium access command from the external apparatus through the USB port, the external storage device determines whether the medium access command aims to access the non-volatile storage medium or the memory module inserted into the expansion slot by interpreting the medium access command, and provides an access service corresponding to the medium access command.

Abstract: The present invention is directed to a cutter having a disposable blade cartridge, a grip for handling by a user, and a coupling arrangement for coupling the cartridge to the grip in such a manner to prevent undesired rotation of the cartridge with respect to the grip. The blade cartridge includes a blade, an upper cover, and a lower cover, the blade being rotatably supported therebetween. The upper cover is further provided with a locking protrusion at one end and a locking recess. The locking protrusion is inserted into a locking aperture that is carried by the grip, thereby acting against a spring-biased pusher within the aperture. The grip further carries a spring-biased locking member that mates with the locking recess of the upper cover. To attach the blade cartridge to the grip, the locking protrusion is inserted into the locking aperture, against the spring-biased pusher. The cartridge is then rotated 90° clockwise, thereby locking the protrusion in the aperture.
