Patent number: 11997239Abstract: A printing apparatus includes a printing section performing printing, and a USB-Type-C interface configured to perform switching to a first state in which a printing operation is executed or a second state in which the power is supplied to the external device. The USB-Type-C interface includes a state identification terminal held at a first potential indicating that the USB-Type-C interface is coupled in the first state or a second potential indicating that the USB-Type-C interface is coupled in the second state. The state identification terminal is periodically switched between the first potential and the second potential during a unit time when the external device is not coupled to the USB-Type-C interface, and in the unit time, a time at which the state identification terminal is held at the second potential is longer than a time at which the state identification terminal is held at the first potential.Type: GrantFiled: February 28, 2022Date of Patent: May 28, 2024Assignee: Seiko Epson CorporationInventors: Takuto Mori, Katsuo Takeuchi, Toru Matsuyama

Patent number: 11887922Abstract: An electronic apparatus includes an integrated circuit board; a printed circuit board electrically coupled to first and second external circuits; and a ball grid array that couples the integrated circuit board and the printed circuit board, includes a first group including pieces of first ball grid, and includes a second group including pieces of second ball grid. The first group couples the first circuit block and the first external circuit. The second group couples the second circuit block and the second external circuit. The number of the pieces of first ball grid is larger than the number of the pieces of second ball grid. The minimum distance between the first group and the first side is shorter than the minimum distance between the group and the first side and is shorter than the minimum distance between the second group and the second side.Type: GrantFiled: September 2, 2021Date of Patent: January 30, 2024Assignee: Seiko Epson CorporationInventor: Katsuo Takeuchi

Patent number: 11579821Abstract: A printing apparatus includes: a printing section including a plurality of printing elements that performs printing on a medium; a power supply circuit supplying power to the printing section; a control circuit controlling the printing section and the power supply circuit; and a USB-Type-C interface configured to couple an external device and including a data transmission/reception terminal, a power input/output terminal, and a state identification terminal. When the state identification terminal detects that the external device that receives the power via the power input/output terminal is coupled, and the printing section performs printing, an amount of power supplied to the external device is large in a case in which a drive rate of the plurality of printing elements is low as compared with a case in which the drive rate of the plurality of printing elements is high.Type: GrantFiled: February 28, 2022Date of Patent: February 14, 2023Assignee: Seiko Epson CorporationInventors: Takuto Mori, Katsuo Takeuchi, Toru Matsuyama
