  • Patent number: 6615058
    Abstract: A personal communication device is folded for compact portability, yet allows viewing of certain essential data such as caller phone number, signal sensitivity, cell boundaries, battery life and messages, without unfolding the phone as well as accessing important function keys. This is made possible by arranging a part of the display section to be in view even when the phone is folded for carrying. When the ear piece of the phone is opened for telephoning, the overall length of the phone is such that the mouth section is opposite to the user's mouth. In the basic design the receiver is located in the movable ear piece so that its length can be kept short. The keyboard section can be located on any surface of the main body of the phone, and an example shows a side mounted keyboard section, thus allowing to operate the phone without unfolding the phone.

  • Publication number: 20030153372
    Abstract: This invention relates to a folding portable information terminal including an upper unit having a display section on one surface, a lower unit having an operating section on one surface, and a movable joining member which openably and pivotally couples the upper and lower units to each other or openably couples the units to each other at one end of each of the units.

  • Publication number: 20030064688
    Abstract: A portable communication apparatus includes a first unit having at least a display section and a second unit having at least a main operation section, which are coupled by a slide coupling and are freely slidable in a longitudinal direction between a retracted state and an extended state. The first unit and the second unit are urged by an urging member in an extension direction and are releasably locked by a releasable lock mechanism in the retracted state. The locking is released by a predetermined operation. An optical aperture for optical function is provided in one of surfaces of the first and second units that face one another in the retracted state. The optical function section is made operable when the first and second units are positioned in the extended state.

  • Publication number: 20030064758
    Abstract: A foldable portable information terminal includes an upper unit having a display unit on its one side, a lower unit having operation keys on its one side, and a movable connecting mechanism connecting the upper unit and the lower unit allowing the upper unit to be opened, closed, and freely rotated with respect to a longitudinal direction of the lower unit. The displaying mode of the display unit whose direction varies depending on a position of the upper unit is changed depending on a positional relationship of the upper unit and the lower unit.

  • Publication number: 20030025669
    Abstract: An inputting device, an electronic instrument using this inputting device, and an inputting method thereof, in which displacement of an operating section in the direction slanting for the X or the Y direction is detected and the movement of a moving object such as a cursor on a display can be controlled easily and precisely, are provided. The operating section is displaced about in the horizontal direction and the vertical direction for a plane being almost parallel to the surface of a cabinet. In case that orthogonal coordinates having the X axis and the Y axis are set on the plane being almost parallel to the surface of the cabinet, horizontal direction sensors detect the displacement of the operating section in the direction slanting for the X or Y direction, in addition to in the X or Y direction. The cursor moves on the display based on the displacement of the operating section about in the horizontal direction.

  • Publication number: 20020159179
    Abstract: A data recording and reproducing apparatus has a reproduction-only mode capable of reproducing a voice file and a recording and reproducing mode capable of recording and reproducing a voice file as an operating mode. An operating mode switching section automatically switches the operating mode to the recording and reproducing mode when an instruction to record a voice file is given in the reproduction-only mode. A recording section records the voice file after the operating mode is switched to the reproduction-only mode.
