A toilet seat apparatus according to an embodiment includes: a toilet seat on which a user sits; a light emitting unit including a light emitting element that emits light; a light receiving unit including a light receiving element that receives light; and a control unit that controls energization of the light emitting element and application of voltage to the light receiving element, in which the control unit performs light reception control including transmitting a control instruction to open an electronic shutter to the light receiving element and energizing the light emitting element so as to permit reception of the reflected light from feces, and performs control of setting an interval from a start of execution of one light reception control to execution of light reception control subsequent to the one light reception control, to 0.2 milliseconds or more.

Toilet seat apparatus and excrement detection apparatus

A toilet seat apparatus according to an embodiment is a toilet seat apparatus to be placed on an upper part of a toilet bowl having a bowl unit that receives excrement, the toilet seat apparatus including: a toilet seat on which a user sits; a light emitting unit including one or more light emitting elements that emit light in a front direction; a light receiving unit including a light receiving element that receives light; and a housing in which the light emitting unit and the light receiving unit are arranged, in which the one or more light emitting elements are arranged in parallel with the light receiving unit or in front of the light receiving unit in a side view or a top view of the housing.

A toilet seat apparatus according to an embodiment is a toilet seat apparatus to be placed on an upper part of a toilet bowl, the toilet seat apparatus including: a toilet seat on which a user sits; a light emitting unit that emits light; and a light receiving unit that receives light; first memory that stores data received by the light receiving unit; and an arithmetic processing device that executes transfer of data received by the light receiving unit to the first memory, and analysis and deletion of data stored in the first memory, in which the arithmetic processing device transfers the data received by the light receiving unit to the first memory, and deletes the data temporarily stored in the first memory when the data has been analyzed to be data that is not data based on the reflected light from falling feces.

An object of the present invention is to provide a remote control apparatus for a toilet seat apparatus which generates electric power by a user's pressing operation, the remote control apparatus being capable of balancing design quality and transmission accuracy of a signal at a high level. A remote control apparatus RC has a main button group MB, including a water spray button WB and a water stop button MB, and a sub-button group SB, including a stronger button SB, etc. Each button in the sub-button group SB has a circular shape with a diameter smaller than that of each button in the main button group MB from a front view. When a button in the main button group MB is pressed, mechanical energy is transferred to a power generation unit GU by a first slide memberand a second slide member. On the other hand, when a button in the sub-button group SB is pressed, mechanical energy is transferred only by the second slide memberand a loss in the mechanical energy in such situation is smaller than the situation where a button in the main button group MB is pressed.

Remote control apparatus

An object of the present invention is to provide a remote control apparatus for a toilet seat apparatus which generates electric power by a user's pressing operation, the remote control apparatus being capable of balancing operability and the ability to reliably stop water spray at a high level. When a cleansing button MB, being a button other than a stop button MB, is pressed, a slide memberreceives force F' at a branch. When the branchslides in a direction indicated by an arrow A, a main partalso slides in a direction indicated by an arrow A. A power generation unit GU generates electric power using mechanical energy input by a pressing force of an output partof the slide member. When the stop button MBis pressed, the slide memberreceives force Fat a stop input partand slides in the direction indicated by an arrow A. At this time, a loss in the mechanical energy caused until it is transferred to the power generation unit GU by the slide memberis smaller than that caused as a result of the pressing operation of the cleansing button MB
