Abstract: A control structure. A main body pivots on a corner of an electronic device. The main body has a contact portion, an arm extending in a first direction from one side of the contact portion, and a connecting portion connected to another side of the contact portion. A shaft in the electronic device is connected to the connecting portion. When the contact portion is pressed and rotates around the shaft, the arm contacts the switch.

Abstract: A card ejecting mechanism includes a push member movable relative to a card retainer, and a buffer member including a retarding piece formed thereon and disposed between the card retainer and the push member in such a manner that when the push member is moved to an ejection position, the buffer member bends toward the card retainer so as to abut slidably against a card kept in the card retainer, thereby retarding the ejecting force when the card is ejected from the card retainer.

Abstract: A frame mechanism for facilitating replacement of an electronic device from a computer, which includes a pivotal parallelepiped frame having a mounting side for installing the electronic device (e.g., CD-ROM drive etc.) therethrough. A pivot member of the frame is coupled to a mating pivot member of a parallelepiped cavity provided on the case enabling the frame to be pivotally rotated about the connection of the pivot member and the mating pivot member and enabling first, second, and third engagement members of the frame to be coupled to first, second, and third mating engagement members provided on the cavity while the frame being pivotally rotated, thereby projecting the mounting side of the frame from the cavity to the outside of the computer.

Abstract: A power supply guide device of a computer host is provided as a connection structure between a power supply and a computer case. The power supply guide device comprises a computer case and a power supply placement device. A first guide device is provided on the horizontal plane of the computer case. A first pivotal portion and a second pivotal portion are located at the upper end and the lower end of the vertical plane of the computer case, respectively. The power supply placement device has a space for placing the power supply. A first fastening device above the power supply placement device is fastened with the first guide device. The first pivotal device and the second pivotal device are respectively connected with the first pivotal portion and the second pivotal portion so that the power supply placement device can be pivotally connected with the computer case.

Abstract: A function switch includes a switch base fixed to an apparatus and formed with a plurality of angularly spaced pitches, a knob, base disposed rotatably within an annular opening in the switch base, an external knob disposed on the switch seat and connected securely to the knob base for co-rotation therewith, and a spring member fixed to the knob base and having a resilient extension portion with engaging tongue slidably engaging the switch base to prevent removal therebetween. The engaging tongue collides against a respective groove to generate a clicking sound when the external knob is turned together with the knob base with respect to the switch base.

Abstract: A fast assembly structure module comprises a seat body connected to a control unit at least. The seat body at least has three plate bodies. Each plate body has a plurality of connection holes. The control unit has an arm. A retaining plate, which can be controlled to insert in and extract out a corresponding connection hole, is disposed at the arm. And, the seat body can be combined with a component with projecting sticks corresponding to the connection holes of the plate bodies. Furthermore, the projecting stick is controlled to insert into or extract out the connection hole thorough the retaining plate of the plate body. Thereby, a fast assembly structure for a module can be obtained and a convenient replacement for a damaged part can be reached.
