A lane determining device that determines the lane traveled by the host vehicle traveling on a road with a plurality of lanes in each direction comprises: road geometry obtaining means that obtains road geometry; imaging means that images the road; division line recognition means that recognizes a division line from an image imaged by the imaging means; first path computation means that computes a path of the host vehicle by repeatedly computing a distance from the division line recognized by the division line recognition means to the imaging means; second path computation means that computes a path of the host vehicle based on the road geometry obtained by the road geometry obtaining means and on autonomous navigation; third path computation means that computes a path of the host vehicle based on a first path computed by the first path computation means and on a second path computed by the second path computation means; and traveled lane determination means that determines the lane traveled by the host vehicle based on a third path computed by the third path computation means.

The invention includes an image sensor, a shutter which opens / closes by making a front curtain and a rear curtain travel, a light source which illuminates the image sensor, a control unit which performs control to make the front and rear curtains travel with a predetermined time shift to form a slit-like opening, and to make the light source emit light a predetermined period of time after the start time of traveling of the front and rear curtains, a detection unit which detects the deviation between the position of an image of the recorded slit-like opening and a predetermined reference position, a computation unit which calculates the error between the traveling start timing of the front and rear curtains on the basis of the detected deviation, and a correction unit which corrects the calculated error between the traveling start timing of the front and rear curtains.

A travel device is capable of determining a deviation angle by which the traveling direction thereof deviates from a travel line parallel to a wall by a simple method and of correcting the deviation of the traveling direction. when the travel device travels along a wall along a travel line parallel to the wall and at a fixed distance from the wall, a deviation angle by which the traveling direction of the body deviates from the travel line parallel to the wall by using: tan θ=H / L, where θ is deviation angle, L is a predetermined travel distance and H is a distance of deviation of the body from the travel line parallel to the wall.

An external operating handle mechanism for a mold cased circuit breaker comprising: an external operating handle; a pinion gear coupled to the external operating handle to be rotatable in response to a rotation of the external operating handle; a movable member provided with a rack gear portion coupled to the pinion gear to be linearly movable according to the rotation of the pinion gear, and provided with a handle connecting portion connected to the handle of the mold cased circuit breaker to linearly move the handle of the mold cased circuit breaker; and a guide member for guiding the movable member to linearly move, by which it is easy to control a stroke required for a displacement of the handle of the mold cased circuit breaker and the displacement of the external operating handle according to the stroke, and it is possible to accurately and efficiently transfer power upon performing a reset operation. Accordingly, unreasonable force may not be applied to resin molding components related to the reset operation including a handle among switching mechanisms, and thus damage or deformation of these components and a unsuccessful or imperfect reset operation can be prevented.
