    • In a navigation apparatus, HOV information related to a high-occupancy vehicle lane or carpool lane is added into node data of a node as a part of the node data in map data. The HOV information of all nodes in a highway in a guide route is acquired from the map data to calculate the total number of transfer permit points. When it is determined that a guide for HOV is possible based on the calculated total number of transfer permit points, and then it is determined that an entry distance from the present position to a nearest transfer permit point is in a predetermined range suitable for an entrance guide into the carpool lane, the entry distance is determined to be suitable for the entrance guide into the carpool lane. Thereby the entrance guide into the carpool lane is provided.

    • In a small-sized optical pickup device for enabling to obtain a stable servo-signal, as well as, a focus error signal and a tracking error signal, without receiving ill influences of stray lights from other layers, when recording/reproducing a multi-layer optical disc, a reflection light from the multi-layer optical disc is divided into plural numbers of regions by a diffraction grating. And, it is divided into at least four (4) regions, by a division line in the tangential direction of the optical disc and a division line in the radial direction thereof. Light receiving parts, for detecting either one of grating diffraction lights, i.e., a +1st dimensional grating diffraction light or a −1st dimensional grating diffraction light of a light beam entering into the at least four (4) regions, are aligned, nearly, on a straight line in the radial direction of the optical disc, and light receiving parts for detecting the other dimensional grating diffraction light are aligned, shifting, with respect to a direction nearly coincident with a tangential direction of the optical disc.
    • 在能够获得稳定的伺服信号以及聚焦误差信号和跟踪误差信号的小型光学拾取装置中,在不受到来自其它层的杂散光的不良影响的情况下, 来自多层光盘的反射光通过衍射光栅被分成多个区域。 并且,通过光盘的切线方向的分割线和其径向的分割线将其分割为至少四(4)个区域。 用于检测光栅衍射光中的任一个的光接收部分,即进入至少四(4)个区域的光束的+ 1维光栅衍射光或-1维光栅衍射光, 在光盘的径向上的直线上,并且用于检测另一维度光栅衍射光的光接收部分被对准,相对于与光盘的切线方向几乎一致的方向移位。
