Abstract: A message management unit receives and accumulates a message, wherein the message is distributed for every update, is the message data representing a latest situation of a competition, an explanation generation unit generates an explanatory text for conveying unconveyed information detected from the message, based on conveyed information, a speech synthesis unit outputs a speech converted from the explanatory text, wherein the explanation generation unit stores the unconveyed information for the explanatory text as the conveyed information, stands by until completion of completion of the speech, and initiates a procedure for generating a new explanatory text based on updated unconveyed information.

Abstract: A lid (120), which is provided on a body of an acoustic device and moves as being able to open or close a front side thereof where an insertion slot is provided for inserting a recording medium, is moved by driving a motor (211) of a drive section (210) with an operation of an open/close button of a movement controller (234) of a movement control device (200). A temperature sensor (220) detects a temperature of a heading space of the lid on a movement path in a first direction, and the movement thereof is stopped when the temperature is within a predetermined temperature range. The movement is recovered when the predetermined temperature is not detected after a predetermined time has passed. When a contact sensor (233) recognizes the contact between the lid and an object to be contacted, the moving direction is reversed for only a predetermined time. When a temperature determining section (232) recognizes a temperature change within the predetermined time, the movement is restarted.
