Expanding operating device and operating system

摘要

An expanding operating device (100) has a first connector (106), a second connector (108) and a sensor (104). The first connector (106) has a first shape physically and electrically connectable with a connector (42) provided with an operating device (34). Thus, by connecting the first connector (106) to the connector (42) of the operating device (34), the expanding operating device (100) can be used with the operating device (34) as a single unit, which eventually adds the sensor (104) to the operating device (34). On the other hand, the second connector (108) has a second shape connectable with a connector with the first shape. This allows a connector (40) conventionally connected to the connector of another operating device (36) to be also connected with the second connector (108). Accordingly, if the connector (40) of another device (36) is connected the second connector (108) in a state that the first connector (106) is connected to the connector (42) of the operating device (34), the another device (36) is eventually connected to the operating device (34) via the expanding operating device (100).
