    摘要: A document management system which can reduce the space used in a storage medium of an information processing apparatus which receives data. It is determined whether or not the resolution of image data generated by an image forming apparatus connected to the information processing apparatus managing image data via a network is higher than a predetermined resolution. If the resolution of the generated image data is higher than the predetermined resolution, the resolution of the generated image data is converted into a low resolution. The resultant image data is registered in association with log information in a storage medium, in the information processing apparatus.

    摘要: An antenna apparatus has a first antenna element and a second antenna element branched from one power feed point. The first antenna element and the second antenna element, which have different lengths, are arranged nearly in a loop as a whole with a predetermined clearance provided between distal ends thereof. The first antenna element and the second antenna element are arranged in such a way that the end faces of the distal ends thereof do not face each other with a lengthwise direction of the end face of the distal end of the first antenna element being approximately orthogonal to a lengthwise direction of the end face of the distal end of the second antenna element. Therefore, the antenna apparatus can suppress electric coupling of a plurality of antenna elements which transmit and/or receive radio waves of different frequency bands.
