Abstract: An image reading device (100) includes a lens array (4), a light receiver (6), and at least one light blocking member. The lens array (4) includes first lens bodies arranged in a line in a main scanning direction with predetermined spacing therebetween to converge light from a reading target. The light receiver (6) receives light converged by each first lens body. The at least one light blocking member is disposed between the light receiver (6) and an end of the lens array (4) proximate to the reading target at at least one position corresponding to the predetermined spacing in the main scanning direction. The at least one light blocking member blocks light from the reading target propagating between the first lens bodies, and each of the at least one light blocking member separates optical paths of light converged by ones of the first lens bodies adjacent to each other.

Abstract: Provided is a wiring circuit board capable of suppressing peeling of a terminal from an insulating layer. The wiring circuit board includes a base insulating layer, and a conductive pattern disposed on one surface of the base insulating layer in a thickness direction. The conductive pattern includes a wiring and a terminal. The terminal protrudes from one end edge of the wiring. The terminal includes a first terminal layer and a second terminal layer. A ratio (Y/X) of the volume Y of the wiring in a folded region with respect to the volume X of the terminal is 0.1 or more. The folded region is a region when a region of the terminal when viewed in the thickness direction is folded back toward the opposite side in a protruding direction of the terminal with the one end edge of the wiring as a starting point.

Abstract: An origin determination method includes the steps of adjusting a positional relation between a chuck table and a grinding unit by a moving mechanism such that lower ends of grinding stones and a holding surface are brought apart along a moving direction, moving the chuck table and the grinding unit relative to each other by the moving mechanism such that the lower ends of the grinding stones and the holding surface are brought closer to each other by a predetermined distance, and determining whether a measurement value of a load applied to the holding surface has reached a threshold. If the measurement value is determined to have reached the threshold, a positional relation between the chuck table and the grinding unit at that time is determined to be an origin of the moving mechanism. Otherwise, the step of moving and the step of determining are then performed again.
