The CPU executes a control for distinguishing the display displaying the screen in an active state from the display displaying the screen in an inactive state with respect to at least one of the display. ## Claims ### Claim 1 A mobile terminal device, comprising: a first touch panel comprising a first display; a second touch panel comprising a second display: and at least one processor that outputs a first screen for a first application in an inactive state to the first display while outputting a second screen for a second application, that is different than the first application, in an active state to the second display, wherein the second screen in the active state comprises a linear bar image indicating an active state, while the first screen in the inactive state does not comprise the linear bar image, to thereby visually distinguish the active state of the second screen from the inactive state of the first screen, detects that a touch to the first touch panel is performed while the first screen is being output in an inactive state to the first display while the second screen is being output in an active state to the second display, and, in response to the detection that the touch to the first touch panel is performed while the first screen is being output in an inactive state to the first display while the second screen is being output in an active state to the second display, switches the first screen to the active state, switches the second screen to the inactive state, and moves the linear bar image from the second screen to the first screen to thereby visually distinguish the active state of the first screen from the inactive state of the second screen. ### Claim 2 (depends on 1) The mobile terminal device according to claim 1, wherein screen in the inactive state is further visually distinguished from a screen in the inactive state by having a higher brightness. ### Claim 3 (depends on 1) The mobile terminal device according to claim 1, wherein a screen in the inactive state is further visually distinguished from a screen in the inactive state by having a larger size. ### Claim 4 (depends on 1) The mobile terminal device according to claim 1, wherein the first display includes a first key area for inputting a predetermined information, wherein the second display includes a second key area for inputting a predetermined information, and wherein the at least one processor, in response to the detection that the touch to the first touch panel is performed while the first screen is being output in an inactive state to the first display while the second screen is being output in an active state to the second display, further darkens the second key area of the second display. ### Claim 5 (depends on 1) The mobile terminal device according to claim 1, further comprising: a first key module for inputting predetermined information, capable of being lit and provided corresponding to the first touch panel; and a second key module for inputting predetermined information, capable of being lit and provided corresponding to the second touch panel. wherein the at least on processor, in response to the detection that the touch to the first touch panel is performed while the first screen is being output in an inactive state to the first display while the second screen is being output in an active state to the second display, further darkens the second key module. ### Claim 6 (depends on 1) The mobile terminal device according to claim 1, further comprising: a first cabinet having the first touch panel; a second cabinet comprising the second touch panel; and a mechanical part which connects the first cabinet and the second cabinet such that the first and second cabinets are switchable between a first configuration, in which the first touch panel is exposed externally and the second touch panel is covered by the first cabinet, and a second configuration, in which at least a part of the second touch panel and the first touch panel are exposed externally. ### Claim 7 A non-transitory storage medium storing a computer program which, when executed by a processor, causes the processor to: outputs a first screen for a first application in an inactive state to a first display of a first touch panel while outputting a second screen for a second application, that is different than the first application, in an active state to a second display of a second touch panel, that is different than the first touch panel, wherein the second screen in the active state comprises a linear bar image indicating an active state, while the first screen in the inactive state does not comprise the linear bar image, to thereby visually distinguish the active state of the second screen from the inactive state of the first screen; detect that a touch to the first touch panel is performed while the first screen is being output in an inactive state to the first display of the first touch panel while the second screen is being output in an active state to the second display of the second touch panel; and, in response to the detection that the touch to the first touch panel is performed while the first screen is being output in an inactive state to the first display while the second screen is being output in an active state to the second display, switch the first screen to the active state, switch the second screen to the inactive state, and move the linear bar image from the second screen to the first screen to thereby visually distinguish the active state of the first screen from the inactive state of the second screen. ### Claim 8 A control method of a mobile terminal device comprising a first touch panel comprising a first display, and a second touch panel comprising a second display, wherein the control method comprises: outputting a first screen for a first application in an inactive state to the first display while outputting a second screen for a second application, that is different than the first application, in an active state to the second display, wherein the second screen in the active state comprises a linear bar image indicating an active state, while the first screen in the inactive state does not comprise the linear bar image, to thereby visually distinguish the active state of the second screen from the inactive state of the first screen; detecting that a touch to the first touch panel is performed while the first screen is being output in an inactive state to the first display while the second screen is being output in an active state to the second display; and, in response to the detection that the touch to the first touch panel is performed while the first screen is being output in an inactive state to the first display while the second screen is being output in an active state to the second display, switching the first screen to the active state, switching the second screen to the inactive state, and moving the linear bar image from the second screen to the first screen to thereby visually distinguish the active state of the first screen from the inactive state of the second screen. ### Claim 9 (depends on 1) The mobile terminal device according to claim 1, wherein the first display includes a first key area for inputting a predetermined information, wherein the second display includes a second key area for inputting a predetermined information, and wherein the at least one processor, in response to the detection that the touch to the first touch panel is performed while the first screen is being output in an inactive state to the first display while the second screen is being output in an active state to the second display, displays the linear bar image adjacent to the first key area. ### Claim 10 (depends on 7) The non-transitory storage medium according to claim 7, wherein the first display includes a first key area for inputting a predetermined information, wherein the second display includes a second key area for inputting a predetermined information, and wherein the computer program, when executed by a processor, further causes the processor to, in response to the detection that the touch to the first touch panel is performed while the first screen is being output in an inactive state to the first display while the second screen is being output in an active state to the second display, display the linear bar image adjacent to the first key area. ### Claim 11 (depends on 8) The method according to claim 8, wherein the first display includes a first key area for inputting a predetermined information, wherein the second display includes a second key area for inputting a predetermined information, and wherein the method further comprises, in response to the detection that the touch to the first touch panel is performed while the first screen is being output in an inactive state to the first display while the second screen is being output in an active state to the second display, displaying the linear bar image adjacent to the first key area.
