Publication number: 20240090679Abstract: A seating detection device includes a sensor, a coupler, a power supply, a switch, and a controller. The sensor forms an electric field to detect a change in an electrostatic capacitance. The coupler couples the sensor to a chair. The power supply supplies power for forming the electric field to the sensor. The switch controls transmission of power from the power supply to the sensor. After the switch is turned on, the controller sets a seating threshold based on the change in electrostatic capacitance detected by the sensor. The seating threshold represents a threshold amount of electrostatic capacitance. The controller determines whether an occupant is seated on the chair based on the seating threshold.Type: ApplicationFiled: August 22, 2023Publication date: March 21, 2024Applicant: Toshiba Tec Kabushiki KaishaInventor: Sho KOIKE

Patent number: 11878893Abstract: According to an embodiment, a paper-length detection device includes: a moving mechanism and an angle sensor. The moving mechanism supports a magnet. The moving mechanism causes a first regulatory member to move closer to or further from a second regulatory member in accordance with movement of the first regulatory member. The moving mechanism further causes the magnet to rotate in accordance with the movement of the first regulatory member closer to or further from the second regulatory member. The angle sensor faces the magnet and outputs a signal corresponding to an absolute angle with the magnet.Type: GrantFiled: December 13, 2021Date of Patent: January 23, 2024Assignee: Toshiba Tec Kabushiki KaishaInventor: Sho Koike

Patent number: 11789396Abstract: The image forming apparatus includes a developing device, a toner container, a first mechanism, a toner sensor, and a controller. The developing device adheres toner to an electrostatic latent image on a photoconductor to form a toner image. The toner container supplies toner to the developing device. The first mechanism causes a toner interface to undulate in the toner container. The toner sensor detects a capacitance between a first electrode and a second electrode arranged apart from the first electrode. The controller determines a remaining amount of toner in the toner container based on detection information from the toner sensor.Type: GrantFiled: May 20, 2022Date of Patent: October 17, 2023Assignee: TOSHIBA TEC KABUSHIKI KAISHAInventor: Sho Koike

Patent number: 11175604Abstract: According to one embodiment, an image forming apparatus includes a storage portion, a first electrode, a second electrode, a measuring unit, a detected portion, an image forming unit, and a controller. The storage portion stores a recording material. The measuring unit measures a change of capacitance between the first electrode and the second electrode. The detected portion is located inside the storage portion and is capable of moving so that at least one of a distance to the first electrode and a distance to the second electrode changes. The image forming unit forms an image with the recording material. The controller controls supplying of the recording material to the storage portion in response to the change of the capacitance measured by the measuring unit.Type: GrantFiled: September 17, 2020Date of Patent: November 16, 2021Assignee: TOSHIBA TEC KABUSHIKI KAISHAInventor: Sho Koike
