the application setting screen if the result of determination in step s 65 is u201c yes u201d that is if a long tap operation has been performed on the setting key 72 on which u201c music player u201d is indicated for example the processor 30 displays the input operation setting screen in step s 67 in the other words if the processor 30 has received a long tap operation on the setting key 72 for example the processor 30 displays the input operation setting screen in step s 67 the input operation setting screen for the music player illustrated in fig7 a is displayed for example in the other words the processor 30 displays an input operation setting screen on the display 14 for the music player an example input operation setting screen is shown in fig7 a next the processor 30 performs an input operation setting process in step s 69 for example when an input operation setting process is performed an operation of changing an input operation that corresponds to each finger or the like is accepted in the other words when the processor 30 has performed an input operation setting process the processor 30 accepts an operation of changing an input operation that corresponds to each finger or the like when the processor 30 ends the operation setting process the flow returns to step s 61 and the processor 30 performs the process in step s 61 the processor 30 that performs the process in step s 69 functions as a change unit on the other hand if the result of determination in step s 65.
