Abstract: A switch unit includes a sliding member which is slidable by pressing operation of the operating member, and a supporting member that supports the sliding member. An electrical contact is opened and closed in accordance with sliding movement of the sliding member. The sliding member includes a pedestal, a first projection provided on a pressing operation side and capable of attaching the operating member, and a column provided on a side opposite to the pressing operation side from the pedestal along the sliding direction. The supporting member includes a plate and a first guide provided from the plate to the pressing operation side along the sliding direction. The pedestal has a first through hole through which the first guide passes, and the first guide has a second through hole into which the column is inserted.

Abstract: A power supply circuit includes a first regulator that includes a first input terminal to which a first voltage is input, a first output terminal from which a second voltage is output, and a first adjustment terminal, and adjusts the second voltage based on a voltage of the first adjustment terminal, a second regulator that includes a second input terminal to which the first voltage is input and a second output terminal from which a third voltage is output, and a differential amplifier circuit that outputs, to the first adjustment terminal, a signal corresponding to a difference between the third voltage and a fourth voltage at a first node between a plurality of first resistors connected in series between the first output terminal and a reference potential lower than the second voltage.

Abstract: A detection device includes a sensor configured to detect first information on motion of a human body of a user, and a processor configured to generate fourth information based on second information on biological activity of the user and third information on biological activity of the user acquired from another detection device, and transmit the fourth information to a server, the second information being generated based on the first information.
