Abstract: A protective cover includes a base, a first member, and a second member. The base includes a sliding portion in an axis direction of the base. The first member includes a first sliding slot and a first fixing portion. The first fixing portion is fixed on a casing of an electronic device. The first sliding slot cooperates with the sliding portion to make the first member slide on the base in the axis direction between a position the first member overlapping the base and a position the first member being stretched out from the base, so as to adjust a length of the protecting cover. The second member is disposed on the base and includes a second fixing portion. The second fixing portion is used for being fixed on the casing.

Abstract: A base includes an engaging module, a release button and a code lock module. The release button presses the engaging module to release the host. The code lock module includes a cam assembly, a plurality of dials and a retaining assembly. The cam assembly includes cams arranged along an axis. Each of the dials has a recess for containing one of the cams. The retaining assembly includes a lock head and an elastic element. When one of the dials is rotated to separate one of the cams from the recess, the cam assembly pushes the lock head to be fastened to the release button and make the elastic element deform. When the dials are rotated to allow each recess to contain one cam, the cam assembly moves away from the lock head, and the elastic element restores to drive the lock head to be separated from the release button.

Abstract: An industrial computer includes a first casing, a second casing, a storage unit, a cover, and a heat dissipation unit. The second casing and the first casing form a closed casing, and the outside of the second casing has a containing area. The storage unit is disposed at the containing area. The cover is removably assembled at the second casing to cover the containing area and contact the storage unit. The heat dissipation unit is disposed at the cover.

Abstract: A computer includes a casing, a carrier, a card reader, and a cover. The casing has a containing space and an opening, and the opening communicates with the containing space. The carrier is located in the containing space and is slidably connected with the casing. The card reader is disposed at the carrier. The cover is pivotally connected with the casing, and the cover has a sealing element for covering and sealing the opening.
