The present invention relates to an optical scanning device in which a light beam is incident twice on a deflective reflecting facet and its object is to reduce curvature in scanning line trail or make the curvature substantially zero, or correct scanning line displacement due to the curvature in scanning line trail. Two stationary plane mirrors (13, 14) are disposed to face a deflective reflecting facet (11) which can be rotated about its rotational axis (12) such that a light beam (a1) being incident on and reflected from the deflective reflecting facet (11) is reflected by the two stationary plane mirrors (13, 14) sequentially. The reflected light beam (a3) is incident on and reflected by the deflective reflecting facet (11) again. Assuming that a plane being parallel to the rotational axis (12) and including the light beam (a0) which is first incident on the deflective reflecting facet is an incident plane, the central ray of an emergent light beam (a4) when the emergent light beam (a4) after the second reflection by the deflective reflecting facet (11) is on the incident plane and a straight line as the central ray of a light beam being projected on the incident plane when the deflective reflecting facet (11) is revolved by the maximum rotational angle are set substantially parallel to each other.

A device with weighing capability (or “scale feature”) and also anvil capability (or “tapping feature”) allows accurate and precise filling of an espresso portafilter with coffee grounds for use in beverage preparation. Some versions switch between a protected mode for anvil use, and a weighing mode for accurate weighing of the portafilter and its grounds, by pivoting the entire load cell into and out of a protected location wherein tapping/shocks do not flex/strain the load cell free end. In other versions, one or more stop(s)/limit(s) are near the load cell free end or associated elements, and the free end/elements move during said tapping/shocks but only to the stop(s)/limit(s), corresponding to a safe amount of strain for the load cell. Also, this way, weighing the portafilter and its contents may continue between taps without switching to a separate protected mode.

A self-adjustable anti-chucking device for a vehicle liftgate includes a wedge portion that is attachable to the liftgate and a base portion that is attachable to a vehicle body. The wedge portion includes a wedge-shaped slider block that is biased by a resilient member. The base portion includes an oblique surface shaped to contact a surface of the slider block. When the liftgate is closed and latched, the friction between the slider block and the oblique surface and the biasing force of the resilient member securely hold the liftgate in place. If the liftgate shifts position, the biasing force of the resilient member will cause the slider block to shift to compensate for any change in the liftgate position relative to the vehicle body.
