  • Patent number: 12124695
    Abstract: A mobile terminal device includes a display section having a display screen, an input section having a touch input region on the display screen, and a control section for displaying a plurality of keys. The display screen is provided as a software keyboard where a touch operation on a specific key causes an input of the specific key. In the specific display region on the display screen that can display operation keys on the software keyboard, the control section selects these keys from a previously prepared set of input candidate key groups. In response to a specific operation on the specific display region, the control section allows the plurality of keys to be displayed on the specific display region. In response to touch on a desired key in the specific display region, the control section determines that an input of the key has been performed.

  • Publication number: 20220260108
    Abstract: Provided is a position adjustment mechanism including: a case; a moving member including a first engaging part and a second engaging part; a lock member provided in the case so as to be movable between a lock position for regulating movement of the moving member in a first direction with respect to the case and a separate position for allowing relative movement of the moving member with respect to the case; and a long member. The lock member includes: a first engaged part engaging with the first engaging part in the first direction; and a second engaged part engaging with the second engaging part in the first direction. When the lock member is at the separate position, the lock member regulates separation of the moving member from the case by engagement of the first engaging part with the first engaged part in the first direction.
