  • Publication number: 20090090775
    Abstract: Provided are a printer and an issuing apparatus in which there is no risk of causing a jam even when a user blocks a discharge port of a printed sheet, and in which occurrence of sheet jam can be effectively prevented. In a printer or an issuing apparatus having the printer built-in, a send-out means (16) formed of a pair of rollers with which a sheet is sandwiched from thereabove and therebelow to be conveyed by a rotational force is provided upstream of a discharge port (14a) for discharging the printed sheet. One roller (16a) of the pair of rollers is attached so as to be free to rotate at a leading end of a rockable arm (16c) having a rotation center downstream of a conveyance path and is biased toward another roller (16b) by its own weight or a slight spring force, and a space is provided for allowing the roller to move in a direction in which the roller is spaced apart from the other roller and for tolerating a deflection of the sheet to be transferred.

  • Patent number: 7167190
    Abstract: The invention reduces power consumption when, for example, a mobile personal computer is in a power-saving mode or when a cellular phone is in a wait mode, in an electro-optical apparatus, such as a liquid crystal display of the subfield drive type used as a display apparatus for various apparatuses. Three different settings “64”, “16” and “2” are enabled as the number of gray scale levels in an electro-optical apparatus, the number of subfields becoming smaller as the number of gray scale levels is reduced. When a large number of gray scale levels is not required (when in the power-saving mode, the wait mode, etc.), a low number of gray scale levels is set, so that the own capacitance of a liquid crystal layer and storage capacitance are charged and discharged less often.
