Abstract: The purpose of the present invention is to provide a robot control device capable of efficiently adjusting a parameter. This robot control device comprises: a first application unit that applies a setting parameter to a first safety parameter for verification in a verification mode; a first update unit that updates, on the basis of the first safety parameter, first safety information related to the robot in a verification function in the verification mode; a copy unit that copies the setting parameter; a second application unit that, after switching from the verification mode to the safety mode by a switch unit, applies the setting parameter copied by the copy unit to a second safety parameter; and a second update unit that updates, on the basis of the second safety parameter, second safety information related to the robot in a safety function in the safety mode.

Abstract: A disc reproduction apparatus of the present invention has a signal processing section which displays a pop-up menu and a user interface specific to a title being reproduced by a reproduction section, on a monitor. Upon accepting a user's operation to display the pop-up menu or the user interface, the signal processing section displays only any of the pop-up menu and the user interface on the monitor. Due to such configuration, only any of the pop-up menu and user interface specific to an HDMV mode or BD-J mode title is displayed, and thereby, wrong operations by a user are reduced.
