Abstract: A display controller which displays an electronic book and enables a user to perform intuitive operations when switching between pages to be displayed. A CPU detects a cursor position on the most frontally-displayed one of a plurality of pages in response to a user operation. Further, the CPU extracts respective areas of shapes dependent on the detected cursor position, from an image representing the most frontally-displayed page and an image representing a reverse page with respect to the most frontally-displayed page. Then, the CPU draws the extracted areas on the screen.

Abstract: A client device receives a page file containing a link to data from a server device which manages a plurality of data and downloads the data associated with the link from the server device. The client device receives link control information corresponding to the link included in the page file from the server device, determines whether to edit each link included in the page file based on the link control information, edits the link based on determination result, transmits a request for data associated with the link to the server device based on the edited link and the unedited link, updates the link to the page file based on a download destination of the data in the client device, and stores the page file including the updated link.

Abstract: A switch device includes a switch housing having an operation member receiving part and an operation member which is mounted on the operation member receiving part of the switch housing as the main components. The switch housing has a regulation wall between an engaged region and a predetermined region X where a front end of the operation member is brought into contact with the switch housing by a seesaw operation of the operation member. The regulation wall is positioned such that the regulation wall facingly contacts an extension part of the operation member in a state in which the extension part of the operation member is in contact with the top surface (predetermined region X) of the switch housing, and the regulation wall does not facingly contact the extension part of the operation member when the operation member is mounted on the switch housing.

Abstract: A rocking operation type electric component is presented that includes: an operation knob that has a bottomed case-shaped configuration and is rockably held; a signal generating unit that includes a movable element pressed and driven by the operation knob and generates a different electric signal in response to a position change of the movable element; and a case on which a mounting frame for pivotally supporting the operation knob is protrusively provided formed and in which the signal generating unit is received. A pair of rotation shafts which face each other are protrusively formed on inner wall portions of the operation knob, respectively. Through-holes are respectively formed in a pair of wall portions of the mounting frame which face each other. The rotation shafts are fitted into the through-holes from the outside of the mounting frame to be rotatably supported by the mounting frame.
