Abstract
A cross key is mounted on a headphone. When a support arm and a connection section are pivoted 180 degrees from the (a)-state to change the position of wearing the headphone between left and right, a head-mounted display is set for use by the right eye, and this turns the cross key upside down. Correspondingly, a function allocated to the upper key is allocated to the lower key and a function allocated to the lower key is allocated to the upper key to obtain the (b)-state. In the (b)-state, the functions are changed such that the function allocated to the upper key is allocated to the upper key and the function allocated to the lower key is allocated to the lower key. A cross key does not require any change in key functions and left as is.
