Abstract: A wireless communication device includes an antenna unit including an antenna pattern; a magnetic member arranged over the antenna unit; and a device that acts as a non-contact type integrated circuit, wherein a ratio of an area of the magnetic member to an area of a region including an outermost periphery of the antenna pattern is 90% or more, and wherein a resonant frequency of the wireless communication device has a deviation from a target resonant frequency falls within a range of ?1.720% to +4.334%.

Abstract: A target selection apparatus capable of quickly carrying out selection processing when selecting a desired target according to a target detection result and carrying out image processing on the target. An image corresponding to image data is displayed on a display unit. A drawing line is drawn on the image displayed on the display unit. A target included in the image data is selected based on the drawing line. In response to the drawing line becoming a closed curve, the selected target is determined.

Abstract: A thermal printer which transfers ink to a printing medium to print an image, comprises a transfer unit configured to transfer dye ink to the printing medium to print an image, and transfer an overcoat onto the entire image to protect the image; and a control unit configured to control transfer of the overcoat by the transfer unit. The control unit forms a region where no overcoat is transferred to embed information in the overcoat, and forms, in the vicinity of the region where no overcoat is transferred, a pattern for hiding the information, to avoid visual perception of the information by a difference in gloss between the region where no overcoat is transferred and a region where the overcoat is transferred.

Abstract: A printing method of printing an image corresponding to one frame by using inks of a plurality of colors applied to an ink ribbon allows a printing apparatus to print one image on continuous paper by using inks corresponding to a plurality of ink surfaces. When printing one print image by using a plurality of ink surfaces on an ink ribbon, the printing apparatus sets an area in the print image to be printed by one ink surface on the ink ribbon, by dividing the print image. The printing apparatus then prints one print image by using a plurality of ink surfaces on the ink ribbon based on the set area.

Abstract: This invention is directed to simplify operation to be performed by an operator and allow authentication processing between two apparatuses while each apparatus uses a single wireless communication unit. For this purpose, when an authentication start instruction button is operated, a host apparatus decreases its RF power to set a communication range to about several ten cm. The host transmits an inquiry signal containing verification data and time interval data. A device which has received this inquiry signal transmits an inquiry response signal containing verification data and information for specifying itself at instructed time intervals. The host transmits authentication information only when this inquiry response is received at the set time intervals, the inquiry response contains verification data, the reception signal intensity changes in a predetermined range, and the inquiry response is sent from one device.

Abstract: A wireless communication apparatus which wirelessly communicates with other communication apparatus or apparatuses, comprises a setting unit that sets a maximum number of other communication apparatus or apparatuses up to which the wireless communication apparatus authenticates to perform wireless communication, a storage unit that stores said maximum number set by said setting unit, and an authentication unit that authenticates other communication apparatus or apparatuses within said maximum number stored in said storage unit.
