Abstract: In an information processing device, a first device includes a first wireless communicator, a determiner that determines a movement pattern of the first device, and a notifier that notifies movement pattern information which indicates the movement pattern determined by the determiner via the first wireless communicator, and a second device includes a second wireless communicator that performs wireless communication with the first wireless communicator a the directional antenna, a driver that rotates the directional antenna, and a controller that performs control to drive the driver to rotate the directional antenna according to the notified movement pattern information, so that it is possible to enhance a radio field intensity of wireless communication between the first device and the second device.

Abstract: A printed wiring board having a land for surface-mounting of an electronic component, includes the land having a pair of land pieces arranged in an opposing manner, and each of the land pieces including a plurality of land portions having widths different from each other, and a coupling portion partially coupling a boundary portion between a pair of adjacent ones of the land portions.
