A pulse transmitting device is provided to avoid interference between pulses due to multipath influence even in a high speed pulse transmission that is typical of a UWB by making use of a relatively simple method and to improve receiving quality. In the device, a pulse adjusting unit (110) generates pulses in response to transmitting data, a non-use interval setting unit (120) sets up a non-use interval where the pulses generated by the pulse adjusting unit (110) are not transmitted on the basis of a delay time that a delayed pulse caused by the multipath delays from a main pulse and takes until arriving at a communication partner. A pulse position adjusting unit (130) adjusts a pulse position not to transmit the pulses during the non-use pulse interval. An RF transmitting unit (140) converts the pulse, the position of which is adjusted by the pulse position adjusting unit, to a wireless frequency band and transmits a pulse wireless signal after the conversion to the communication partner.

An MPF (Multi Function Peripheral) obtains a BD address and a device name from a communication partner search response when it receives the communication partner search response from a cellular phone. When the MFP successfully obtains the BD address and the BD address is stored in a device management database in a RAM of the MFP, the MFP obtains a user name corresponding to the BD address from the device management database. The MFP obtains settings associated with the user name from an environment database in the RAM of the MFP and stores the same in an environment storage area in the RAM. A display process, etc. in the MFP are performed according to the settings stored in the environment storage area.

As a rotating member of an operating unit is operated, a graphical user interface works so that a band-shaped display area wound on a roll-shaped object looks like being extended upward in visually the same direction as the direction of rotation of the rotating member, from the roll-shaped object. In this case, left and right ends of the roll-shaped object move to look like rotating. When the band-shaped display area is fully extended, the left and right ends stop rotating. Thus, a graphical user interface is provided which does not require a user to repeat troublesome operations until an information processing device executes processing desired by the user, and which enables improvement in user-friendliness.
