A sliding display device includes a housing, a flexible display panel, a first roller, and a second roller. The housing includes a display region between a first edge region and a second edge region. The distance between the first and second edge regions changes as the housing is expanded and contracted. The flexible display panel slides into and out from the housing through the first and second edge regions as the housing expands and contracts. The first and second rollers guide panel regions into and out of empty spaces in the housing. An assistant roller assists in moving one of the panel regions along a non-intersecting path.

Sliding display device

A rollable display device includes a rollable structure including a plurality of unit structures, the rollable structure being rollable and unrollable based on the unit structures, and a display panel structure attached to the rollable structure, wherein respective widths of the unit structures increase in a direction from a first side of the rollable structure to a second side of the rollable structure, the first side of the rollable structure being opposite to the second side of the rollable structure, and wherein each of the unit structures includes a metal plate, the metal plate being bent by a bending limit angle in a direction in which the rollable structure is rolled, and a magnetic object on a side region of the metal plate, the magnetic object being magnetically coupled to an adjacent metal plate.

Rollable display device and electronic device including the same

A mobile terminal having restricted access to an enhanced services system includes a transceiver which transmits and receives wireless signals, a memory which stores a first preferred roaming list (PRL) listing a basic communication system and an enhanced services system, and a second PRL listing the basic communication system but not the enhanced services system, and a controller which restricts access of the mobile terminal to the enhanced services system by deactivating the first PRL and activating the second PRL in response to receipt of an authentication failure report from the enhanced services system. A system for restricting access to an enhanced services system includes an enhanced services system which provides enhanced services to authorized users and prevents unauthorized users from communicating with the enhanced services system.

Mobile terminal, system and method for controlling access to an enhanced services system

A finishing apparatus of an image forming apparatus and a method for controlling the same are disclosed, in which various block modules performing finishing functions are provided and a user can selectively use any module by detachably fixing the same in a copier. The finishing apparatus includes a paper conveyer module detachably fixed to an image tray module, a mail box module, a finisher module, and a booklet module, the paper conveyer module being detachably fixed in a copier. The paper conveyer module includes a controller sensing whether the respective modules are detachably provided to selectively control functions of the respective modules in accordance with an output signal of the copier. In addition, paper path switch devices provided in the paper conveyer module include a plurality of paper dispensers that dispense papers in three or more directions.

Finishing apparatus of image forming apparatus

A tape feeder and a method of controlling the same are disclosed, in which an automatic feeding tape and a manual feeding tape are selectively fed to a binding device. In the method of controlling a tape feeder comprising a tape feeding portion structured to selectively feed manual feeding tapes and automatic feeding tapes to a tape heating unit, a stack cassette having the automatic feeding tapes therein, and a tape moving path moving the automatic feeding tapes in the stack cassette to the tape feeding portion, wherein the tape moving path includes a slot into which the manual feeding tapes are externally input, an automatic feeding tape sensor, and a tape feeding sensor, and the tape feeding portion includes a tape aligning position sensor sensing the position where the automatic feeding tape or the manual feeding tape has been fed to the tape heating unit, the method is characterized in that the manual feeding tape prior to the automatic feeding tape is moved to the tape feeding portion by a signal of the tape feeding sensor when the automatic feeding tape sensor and the tape feeding sensor respectively sense the automatic feeding tape and the manual feeding tape.

Tape feeder and method of controlling the same

A paper binding system of an image forming apparatus, such as a printer and a copier, and a method for controlling the same are disclosed, in which finishing processes such as stapling and folding are performed by exactly gripping papers ejected from the image forming apparatus without any scattering. The paper binding system of the image forming apparatus includes a paper moving meansmoving papers ejected from the image forming apparatus, a paper positioning unittemporarily receiving the papers moved from the paper moving means and positioning them, a stapler unitstapling the papers received in the paper positioning unit, a folding meansfolding the stapled papers, and an eject trayreceiving the papers finished through the stapler unit and/or the folding means.
