Abstract: An electronic device with component detaching function includes a casing, a cover and an electronic component. An opening is formed on the casing. The cover is adapted to shelter the opening. The cover is movably disposed on the casing close to the opening, and can move relative to the casing to be switched between a first position and a second portion. The cover includes a first connecting portion. The electronic component including a second connecting portion is detachably disposed on the opening. The second connecting portion is detachably assembled with the first connecting portion. When the electronic component is separated from the casing, the electronic component utilizes an assembly of the first connecting portion and the second connecting portion to slide the cover relative to the casing, and the cover moves from the first position to the second portion.

Abstract: The present invention discloses a protective cover mechanism for protecting a socket of an electronic device. The protective cover mechanism includes a base and a fluid restrictor. The base is disposed on the socket for covering the socket. The fluid restrictor is installed on the base and is for blocking airflow on a side of the socket, so as to guide the airflow to a neighboring electronic component.

Abstract: Methods for detecting a short-circuit problem and an open-circuit problem in an ink jet printer. The ink jet printer includes at least an ink jet unit having an input end, a corresponding nozzle, and a control end. The ink jet printer further includes a driving circuit for providing energy to the ink jet unit via the input end. When the ink jet unit receives an ink jet signal via the control end, the ink jet unit can spray ink via the corresponding nozzle according to the energy received via the input end. The short-circuit problem detecting method includes stopping transmitting the ink jet signal to the control end of the ink jet unit, stopping providing energy to the input end of the ink jet unit, and measuring currents flowing through the input end of the ink jet unit.
