Abstract: According to one embodiment, a checkout apparatus includes an apparatus body, a monitor, a rotation mechanism, a lock mechanism, a notification unit, and a control unit. The apparatus body can switch a mode for checkout processing between a cashier mode in which a cashier operates the apparatus and a self-service mode in which a customer operates the apparatus. The monitor is provided on the apparatus body and displays a status of the checkout processing. The rotation mechanism rotates the apparatus body. The lock mechanism locks the rotation of the rotation mechanism at least at two positions. The notification unit causes the monitor to display guidance showing a procedure for mode switching, including locking and unlocking by the lock mechanism. The control unit switches checkout processing modes in response to that the rotation of the rotation mechanism is stopped at one of the positions with the locking by the lock mechanism.

Abstract: A computer acquires maximum lengths of a structure as measured along X-axis, Y-axis, and Z-axis directions, and acquires numbers of divisions of line segments which extend along the X-axis, Y-axis, and Z-axis directions, respectively, and have the maximum lengths, respectively. The computer then calculates a basic shape, which is the shape of a rectangular parallelepiped divided into a three-dimensional grid, on the basis of the maximum lengths and the numbers of divisions. The computer creates a basic frame of the structure from the basic shape by deleting a selected line, and adding a line between two selected grid points. The computer calculates structure data, which are three-dimensional data representing the structure, by arranging frame members, which are represented by three-dimensional frame member data, along lines between the grid points of the basic frame. The computer then outputs a drawing of the structure from the structure data.

Abstract: A protector comprising an inner tube, a lid connected to the upper opening of the inner tube through a hinge, and an outer tube for holding the inner tube in its inner cavity part. A blood collecting needle to which a tube is connected is stored in the inner tube. The inner tube comprises an annular seat face which seats on the base end part of a hub formed integrally with the blood collecting needle when the blood collecting needle moves downward. An operation lever extending downward is installed at the side of the lid, and the end part of the operation lever is slightly projected outward. When the blood collecting needle is moved, the inner tube is pulled integrally with the tube by the annular seat face to be slid relative to the outer tube until the end part abuts on the lower end part of an operation hole. Then, the lid is closed and the blood collecting needle is stored in the inner tube.
