  • Patent number: 9878700
    Abstract: An indicator apparatus for a hybrid vehicle includes a display region having a range that extends between first and second ends of the display region. The display region displays a first mark to indicate to the driver a first state amount that changes in accordance with the output demand from the driver, a first edge of the first mark moving across the range between the first and second ends of the display region as the first state amount changes. A second mark having a second edge is displayed so that the second edge extends across and overlaps the display region, the second edge indicating to the driver a threshold at which switching occurs between an EV traveling mode and an HV traveling mode.

  • Patent number: 8988204
    Abstract: A communication unit periodically transmits a request signal toward a prescribed range. When a transmitter exists in the range where the request signal can be received, it sends identification information in a responsive manner. A comparison ECU compares the identification information provided from the communication unit with a predetermined value, and if both of them match with each other, notifies a matching notification to a power source management ECU. On receipt of the matching notification from the comparison ECU, the power source management ECU notifies a lighting-up request for providing an instruction for lighting-up of a light-emitting unit to a body ECU. Upon receipt of the lighting-up request, the body ECU activates a lighting-up command LON. As a result, the light-emitting unit is lit up and notifies a user of the position of a charging port.

  • Patent number: 8134334
    Abstract: Light applied from an illumination unit illuminates a space formed of an accommodation unit, and facilitates a user's operation of coupling a charging connector to an electric power-receiving unit. When a lid unit is in a closed state, a part of the light applied from the illumination unit toward the accommodation unit transmits through a light transmission member provided at the lid unit and leaks toward a space outside a vehicle body. The leaked light enables a user to visually perceive the position of the charging port at a glance even if the lid unit is in the closed state.

  • Patent number: 7824791
    Abstract: An electronic apparatus includes an outer housing; a battery storage compartment provided in the outer housing and having a height and a width and depth larger than the height; a cover for opening and closing an opening of the battery storage compartment; and a battery ejecting spring disposed in a deep portion of the battery storage compartment and for urging a battery being stored in the battery storage compartment along a direction of ejection of the battery from the opening. The battery ejecting spring includes a pivot shaft, an anchor shaft, and an urging shaft. The pivot shaft extends along the width direction. The anchor shaft stops the rotation of the one end portion of the pivot shaft. The urging shaft includes a tip end engaging with an end face of the battery, thereby to perform a pivotal movement about the pivot shaft working as a fulcrum.
