Abstract: Solved is a problem of difficulty in operating, with an operation unit casing held by one hand, both of a touch panel and a key operation unit without changing the hand which holds the unit. A portable terminal device comprising an operation unit casing 10 having a key operation unit 15 formed of a key switch and a display unit casing 20 having a display unit and a touch panel 30, in which the display unit casing is laterally positioned with respect to the operation unit casing such that both of the key operation unit 15 and the touch panel 30 are operable by one-handed operation by a hand which holds the operation unit casing 10.

Abstract: A data storage unit (2) associates data which is transmitted from a poster's terminal with the date and time at which the data is transmitted and stores same. A setting unit (5) sets, in identifying information of a user who views the poster's data, a viewing interval wherein the data may be viewed. In response to a data access request which is transmitted from a user terminal, a control unit (6) refers to the date and time of the data which is stored in the data storage unit (2) and the viewing interval which is set in the identifying information of the user which is included in the data access request, and if the date and time are included in the viewing interval, transmits to the user terminal the data which is transmitted at said date and time.

Abstract: An electronic apparatus includes a display unit configured to display an image, an operation unit capable of detecting plural input positions, and a control unit. The control unit computes an operation target region that is formed by the plural input positions detected by the operation unit and performs first processing on plural operation targets included in the operation target region and associated with the image displayed on the display unit, according to a change in the area of the operation target region.

Abstract: An object of the present invention is to provide a sliding mechanism with which when a state of two connected members is changed to a plurality of states by sliding, the state can be changed from an arbitrary state to another arbitrary state without passing through the other state. The sliding mechanism of the present invention is disposed between a first member and a second member and includes a body to be guided arranged on the first member and a guide body arranged on the second member and guides the body to be guided. The guide body includes an annular guide groove which guides the body to be guided. The guide groove is a groove section composed of at least three sides including an arc-shaped side and a linear side.
