Provided are an operation panel capable of reliably pressing down a target operation key while saving arrangement space of operation keys, an image forming device provided with the same, and an image reading device. An operation panel (3) is provided with a main body unit (10) having a panel surface (10a) tilted with respect to a horizontal direction and operation keys (12 to 16) protruded from the panel surface. The operation keys have operation surfaces (12a to 16a) pressed down by a user and protrusion portions (12b to 16b) formed so as to be protruded from the operation surfaces along lower end portions of the operation surfaces.

The present invention relates to a keyboard switch including a base, a supporting member, a spring, a button and an upper cover. The supporting member includes a first plate connected to the base to seal the opening, a tube extending substantially perpendicularly from a surface of the first plate, and a plurality of blocks extending substantially perpendicularly from the first plate and configured around the tube. There is a gap between the tube and the plurality of blocks. The base and the supporting member may be made of different materials and colors from the base, so that the supporting member may have a good light-shielding performance and durability; and the base may be made of a collocation of different materials and colors, and has a wide design space.

A key structure including a bottom plate, a switch element, a keycap, a positioning element, and a linkage rod is provided. The switch element is disposed on the bottom plate. The keycap is disposed on the switch element, and the switch element is located between the bottom plate and the keycap. The positioning element is connected to the bottom plate and located between the bottom plate and the keycap. The linkage rod is disposed between the keycap and the positioning element. The linkage rod has a portion disposed at a position corresponding to a groove, and two opposite sides of the linkage rod are each in contact with the keycap and the positioning element.

An electronic apparatus is configured for processing a network communication operation. The electronic apparatus includes a frame and a plurality of electronic modules. The plurality of electronic modules are disposed on the frame and each electronic module is closely surrounded by other electronic modules for forming a pillar-shape wind channel, such that the electronic apparatus is assisted to process a heat dissipation.

A connector combination includes a transmission line and a connector. The transmission line includes a woven shield for providing a signal reference of a radio-frequency signal, and blocking noise to prevent the radio-frequency signal from being interfered with the noise. The connector is coupled to the transmission line, includes a pipe, wherein a soldering area is formed on the pipe for allowing the woven shield to be soldered with the pipe after the transmission line is combined with the connector.

A fan carrier apparatus for an electronic apparatus includes a base, at least one fan and a current-conduction module. The base includes at least one opening. The at least one fan is disposed at the at least one opening of the base. The current-conduction module is disposed on the base and includes at least one hole. Accordingly, an air corresponding to the at least one fan penetrates the at least one hole to assist heat dissipation of the electronic apparatus.

A power supply system includes: a power supply terminal, for receiving first power from an external power source or outputting second power to a load; at least one battery, for receiving and storing first power in a charging mode, and outputting second power to the power supply terminal in a discharging mode; a charger, enabled in the charging mode for charging the battery by first power; a switch, turned on in the discharging mode for transmitting second power to the power supply terminal; a current detection circuit, for detecting a current of the power supply terminal to determine whether the power supply system is operated in the charging or discharging mode. The current detection circuit controls the charger to be enabled in the charging mode and disabled in the discharging mode, and controls the switch to be turned on in the discharging mode and turned off in the charging mode.

A button structure applied in an electronic device includes at least a flexible connector connected to a circuit board of the electronic device and a pressing portion located at a terminal of the at least a flexible connector. When a user presses the pressing portion, the pressing portion applies an acting force on the at least a flexible connector and the at least a flexible connector generates an electrical signal to the circuit board.
