[Problem] The purpose of the present invention is to provide a device that is capable of content display with good operability or with a relatively simple configuration. [Solution] A control frame control means 4 detects when a control button which controls the display content of a content frame 22 is clicked in a control frame 2. Addressed to a content frame control means 8, said control frame control means 4 sends an indication that the control button has been clicked to a shared control means 8, which is the control means above the control frame control means 4. Among directly controlled control means, the common control means 8 receiving said indication does not have a content frame control means 8, to which the indication is addressed, so forwards said indication a lower-level shared control means 9. Among directly controlled control means, the lower-level shared control means 9 has a content frame control means 6 to which the indication of the clicked control button is addressed, so sends said indication thereto. Receiving this, the content frame control means 6 controls display in the content frame 22. |
