  • Publication number: 20240183510
    Abstract: A light emitting apparatus is supported by a second support supported by a first support laterally relative to the first support alongside an imaging apparatus, and emits light to be detected by the imaging apparatus. The light emitting apparatus includes a light source that emits the light and a lens on which the light emitted from the light source is incident and that transmits the light incident on the lens. The lens includes a part provided with a dimmer that at least partially reduces light to be emitted to the first support out of the light incident on the lens.

  • Publication number: 20240167901
    Abstract: A pressure-sensing element includes a membrane, a substrate, a guard, and a base. The membrane includes a diaphragm. The substrate is opposite to the membrane in a thickness direction. The guard is between the membrane and the substrate and is bonded to the membrane and the substrate. The guard has a closed shape. The base is in an enclosed space defined by the membrane, the substrate, and the guard. The base is bonded to the membrane and is separated from the substrate and the guard. The base includes a first electrode opposed to the diaphragm with a pressure reference chamber between the first electrode and the diaphragm to provide electrostatic capacitance. The base except for the first electrode is bonded to the membrane. A trench extends in the thickness direction entirely through the membrane and partially through the guard.

  • Patent number: 11981531
    Abstract: A sheet feeding device feeds a sheet in a feed direction. The sheet feeding device includes a loading portion, a feeler, and a first detection sensor. The sheet is to be placed on the loading portion. The feeler rotates from a reference position to a pushed position around a support shaft in response to a push by a downstream end of the sheet, which is placed on the loading portion, in the feeding direction. The first detection sensor detects a rotation of the feeler from one of the reference position and the pushed position to the other of the reference position and the pushed position. The loading portion includes a second detection sensor to detect a state in which the sheet is placed on the loading portion.
