Abstract: A vacuum cleaner head capable of implementing a plurality of functions having different cleaning purposes and capable of changing the cleaning mode, thereby performing efficient cleaning without inconvenience is provided. The vacuum cleaner head includes a first part having a first air passage communicating with a main air passage of a cleaner main body, a second part having a plurality of cleaner function units provided at different positions and a plurality of second air passages communicating between each of the cleaner function units and the first air passage. The second part is connected to the first part so that the inclination angle of the second part is changeable in multiple steps. By changing the inclination angle of the second part with respect to the first part, some of the plurality of cleaner function units is disposed so as to be usable and the second air passage is communicated with the first air passage for switching to the portion of the plurality of cleaner function units to be used.

Abstract: An image forming device is provided. The image forming device includes at least one memory, a display configured to display at least one print image based on at least one file, and at least one processor configured to control to select at least one of the at least one displayed print image, as a page to print (print page), based on a received instruction, perform a print process based on the at least one selected print page, acquire the at least one file from at least one file storage area connected to an external system and provide the acquired file to the display, and create print data, based on at least one print page that has received a selection instruction via the selection.

Abstract: A keypad and a slide type mobile terminal having the same are provided. The slide type mobile terminal includes a first main body; a keypad having an upper surface part and a lower surface part, and a second main body coupled to the first plate positioned at one end of the upper surface part of the keypad and slidably connected to the first main body. The upper surface part has a plurality of parallel first plates that form an upper surface of the keypad, and the first plates positioned at each end of the upper surface part each have a downward facing first latch disposed at one side thereof and the remaining first plates each have a downward facing first latch disposed at two sides thereof. The lower surface part has a plurality of parallel second plates that form a lower surface of the keypad, and each second plate has an upward facing second latch disposed at two sides thereof. One second latch of each second plate contacts an adjacent first latch.
