Abstract: Provided is an abnormality detection device, in which a sound signal acquisition unit connected to a passenger conveyor converts a sound wave around each of inspection guide shoes mounted to a step into a sound signal. A sound signal analysis unit analyses the sound signal and extracts a sound pressure or a main frequency. The controller has not only a function as a command unit configured to command an operation for causing the step to run but also a function as an abnormality determination unit configured to determine an abnormality in skirt guards based on the sound pressure or the main frequency. The sound signal analysis unit in the abnormality detection device analyzes the sound signal acquired by the sound signal acquisition unit under a state in which the step is caused to run, and extracts the sound pressure or the main frequency.

Abstract: A search keyword input device includes multiple keyword type selection keys for showing multiple keyword types for the purpose of distinguishing and narrowing down multiple search keywords so as to be selectable, and used for selection of the multiple keyword types, a display unit which corresponds to the multiple keyword type selection keys, and which displays multiple selecting notification display elements for the purpose of notifying that the multiple keyword types are selected, and a control unit for controlling the selecting notification display elements corresponding to the keyword type selection keys to be displayed on the display unit as instructed when the keyword type selection key for selection of the keyword type is instructed.
