Abstract: A filter device 2 is provided with: a filter body 3 equipped with a filtering material 30; and a mesh-like filter cover 5 that is mounted to the filter body 3 in such a manner as to cover at least part of a filtering surface 32 of the filtering material 30. The filter cover 5 is provided with: a purification part 50 which includes multiple layers formed by folding a single sheet of metal mesh material and which has a rectangular shape that is substantially identical to that of the filtering surface 32 in a plan view; and a first leg 51 and a second leg 52 which intersect with the purification part 50 in a side view. The metal mesh material has a finely corrugated surface formed thereon. The entire outer peripheral edge 59 of the filter cover 5 is completely fitted within the filtering surface 32.

Abstract: An example system is provided that controls a standby time for performing contactless communication based on whether the device performing the communication is a stationary or portable device.

Abstract: A device of an example is a portable information processing device performing settlement processing concerning purchase of a merchandise article or a right in cooperation with a given server, comprising: a non-contact communication unit performing non-contact communication with a data storage medium; a data acquisition unit acquiring data stored in the data storage medium, through the non-contact communication unit as a part of the settlement processing; a settlement processing unit performing settlement based on the data acquired by the data acquisition unit, in cooperation with the server, as a part of the settlement processing; a detection unit detecting at least one of attitude, movement, and a placement state of the own device; and a restriction unit acquiring a detection result from the detection unit and then, when the detection result does not satisfy a given condition, restricting performing of at least a part of the settlement processing.

Abstract: An example system includes: a data storage medium including a storage unit storing data concerning settlement and a non-contact communication unit performing non-contact communication; a server device performing settlement processing concerning a merchandise article sold and purchased, based on data stored in the data storage medium; and a plurality of information processing devices including a non-contact communication unit performing non-contact communication with the data storage medium, a data acquisition unit acquiring data stored in the storage unit of the data storage medium through the non-contact communication unit and a settlement processing unit performing settlement processing with the server device based on data acquired by the data acquisition unit. The plurality of information processing devices include a stationary information processing device and a portable information processing device.

Abstract: A detection sensor detects a position of a level detection lever that touches an uppermost sheet of sheets stacked on a holding tray, and a computing device counts the number of sheets that have been discharged to the holding tray. A judging device judges the amount of sheets stacked based on a sheet surface level detection signal from the detection sensor and a count value of the computing device. The apparatus accurately judges that the maximum amount of sheets have been stacked in the holding tray according to the position of the level detection lever and a count value for a number of sheets. Also, the apparatus selects one of a plurality of values for an offset sheet count, which corresponds to the operating conditions, namely the transporting speed of sheets, the intervals between sheets, and the length of the transport direction of the sheets.
