Patent number: 11922389Abstract: A payment terminal includes a camera configured to capture an image, a card slot for inserting a contact type IC card, and a panel arrangement surface on which a touch panel is arranged. A lens of the camera, the card slot, and the panel arrangement surface are arranged in order in the height direction from a placement surface of the payment terminal. The panel arrangement surface is oriented obliquely upward toward a user positioned in front of the card slot. An optical axis direction of the lens is obliquely upward toward the user, and the lens is provided closer to the user than the card slot.Type: GrantFiled: September 3, 2021Date of Patent: March 5, 2024Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Kyohei Kida, Yasuyuki Tanaka, Yasuji Wakiyama, Takeyuki Sasaki, Kohei Takada
