Abstract: An expanding operating device has a first connector, a second connector and a sensor. The first connector has a first shape physically and electrically connectable with a connector provided with an operating device. Thus, by connecting the first connector to the connector of the operating device, the expanding operating device can be used with the operating device as a single unit, which eventually adds the sensor to the operating device. On the other hand, the second connector has a second shape connectable with a connector with the first shape. This allows a connector conventionally connected to the connector of another operating device to be also connected with the second connector. Accordingly, if the connector of another device is connected the second connector in a state that the first connector is connected to the connector of the operating device, the another device is eventually connected to the operating device via the expanding operating device.

Abstract: A biological information measurement device is constituted of an upper cover and a lower cover and a main body portion. Then, the upper cover and the lower cover are assembled such that they partially overlap with each other. A fingertip insertion portion is formed of a holding member, on which a substrate and a line of the main body portion are placed. By covering the whole main body by assembling the upper cover and the lower cover, the substrate and the line of the main body portion arranged on a side surface of the main body in the inside cannot externally be seen.

Abstract: An example portable, handheld game console includes a main body incorporating a first display screen, and a cover body incorporating a second display screen. The main body is hingedly connected to the cover body along adjacent forward and rearward edges, respectively, such that the cover body is movable between closed and open positions. The main body is provided with a plurality of control buttons and a pair of game card slots for receiving game cards of different dimensions. One of the game cards is substantially square and comprises a substantially flat card body having a plurality of electrically conductive terminal strips adjacent the forward edge. One of the side edges of the card has a single continuous step configuration along substantially the entire length dimension of the card.
