A reproducing means for performing reproduction processing on digital data which is read out from a predetermined recording medium recording the digital data, a manipulating means for making an instruction of reproducing the digital data inserted in the recording medium, a control means for reading the digital data from the recording medium in accordance with the reproduction instruction input with the manipulating means and sending it to the reproducing means, and for controlling the reproducing means to perform reproduction processing on the digital data, and a cylindrical case for containing the reproducing means and the control means are provided, and wherein the manipulating means is provided on one end side on one plane in the longitudinal direction of the cylindrical case. Thereby the user can manipulate the manipulating means without taking out a portable recording and/or reproducing device from a bag or a pocket, thus making it possible to remarkably improve its manipulation.
摘要:
A mobile phone base station sends to a mobile phone device information requesting location data thereof, receives location data sent back by the mobile phone device according to the information, and outputs the location data to a location data collection system. The location data collection system inputs the location data, and generates state-of-move information constituted from a location distribution, a moving speed distribution, and a moving direction distribution, or information obtained by filing these information, based on the location data. Then, the location data collection system broadcasts the generated state-of-move information to the car navigation system located in a predetermined area through the mobile phone base station. The car navigation system displays the received state-of-move information on a screen of a display unit thereof with a map indicating the vicinity of the location of the vehicle.
