    摘要： A communication quality evaluation system, a device, a method, and a program for evaluating communication quality at an arbitrary location, in the form which can actually felt by a user, are provided. According to an instruction from an evaluator, a control device displays a map or layout diagram of a specified area on a map/layout diagram display device and specifies an evaluation point within a display range of the map or the layout diagram. According to the network quality estimated by a network quality estimation unit, a network quality simulation unit for estimating the network quality when communications are performed at the evaluation point deteriorates the evaluation data and transmits the data to an evaluation device. The evaluation data deteriorated is a sample of data actually transmitted and received in the communication system. The evaluation device uses a communication device actually used by a user in the communication system.

    摘要： In an aperture stop mechanism, two aperture blades are arranged so as to overlap each other and form a single light passage opening into which light utilized in imaging is introduced with the respective edge portions of the two aperture blades. A drive mechanism drives the two aperture blades in directions different from each other, whereby the aperture area of the light passage opening is changed within a predetermined range. When the two aperture blades are located at a minimum aperture position where the aperture area of the light passage opening is minimum within the predetermined range, the two aperture blades are provided so that the single light passage opening surrounded by boundaries including eight straight lines is constituted of the respective edge portions of the two aperture blades.
