Abstract: The imaging device comprises a first fixed-focus camera, a second fixed-focus camera, and a variable focus camera. The control device reads information of the symbol based on the first image from the first fixed-focus camera, the second image from the second fixed-focus camera, and the third image from the variable focus camera. The control device controls the focal length changing device of the variable focus camera such that the focal length of the variable focus camera is longer than the first focal length of the first fixed-focus camera and shorter than the second focal length of the second fixed-focus camera. The control device reads the information of the symbol based on the third image, which is focused at a distance farther than the first image and closer than the second image, generated by the variable focus camera under the controlled focal length.

Abstract: A sale data processing device includes a member storage memory configured to store input member specification information, and a processor configured to determine whether or not an acquired sale target is a sale target to be sold only to only a member, on the basis of specification information for specifying the sale target. The processor is configured to execute a settlement process related to the sale target only when the sale target is a sale target to be sold to only a member and the member information is stored in the member storage memory.

Abstract: According to an embodiment, a commodity sales data processing apparatus includes a commodity-information acquiring unit configured to acquire commodity information for a commodity associated with a commodity code in a commodity master file. The commodity information includes an on-sale date for the commodity which indicates a particular day/time at which it is acceptable for the commodity to be sold to customers. A commodity identifying unit is configured to identify a first commodity based on the commodity code read from the first commodity. An information presenting unit is configured to cause an information presentation to be performed according to the present date/time and the on-sale date for the first commodity as acquired by the commodity-information acquiring unit for the first commodity.

Abstract: A point of sale device according to an embodiment includes a storage unit, an input unit, a display, a communication interface, and a processor. The input unit receives an input of a customer identification code corresponding to a customer that is performing a transaction. The input unit also receives an input of one or more merchandise information codes each corresponding to a merchandise item that the customer has selected for purchase in the transaction. The processor retrieves, based on the input customer identification code, one or more merchandise reservation codes each corresponding to a merchandise item that the corresponding customer has previously reserved. The display provides a notification that the previously reserved merchandise item is available.

Abstract: A frequency combining circuit in the form of a planar transmission circuit has a four-port directional coupler, two transmission lines respectively coupled to the forward and backward coupling ports of the directional coupler, and two filters respectively coupled to the two transmission lines, one of the two filters being further coupled to a load. By applying a first frequency signal to the coupler input port and applying a second frequency signal to the other one of the filters, the first and second frequency signals are combined in an excellent manner at the coupler output port of the coupler due to the provision of the two filters both of which reject the first frequency signal and pass therethrough the second frequency signal.
