<p>PURPOSE:To give necessary instruction immediately and to use a system effectively by enabling a switching operation element to be operated according to a switching operation procedure which is displayed by operating an operation element different from the switching operation element. CONSTITUTION:This device consists of a master equipment side A equipped with the input means consisting of an input device 7 equipped with the switching operation element operated according to the switching operation procedure predetermined so as to select and supply a specific signal to plural slave equipments, a display device 8, and a controller 9 and a slave equipment side B consisting of plural slave equipments 10A - 10N. The switching operation procedure is displayed by operating an operation element such as a help switch, a return switch, and an image switch different from the switching operation element, and the switching operation elements can be operated according to the switching operation procedure. Therefore, even when the switching operation procedure becomes unclear, that is securely relieved and the switching operation elements can securely be switched. Consequently, group learning is carried out effectively.</p> |
