Abstract: A reference core position calculation device 100 that calculates a reference core position of an elevator shaft in which an elevator is to be installed includes a measurement unit 101 and a calculation unit 112. The measurement unit 101 measures a dimension of each portion of the elevator shaft. The calculation unit 112 calculates portion dimension values of the elevator shaft based on the reference core position and the dimension of each portion measured by the measurement unit 101. When the reference core position is a first reference core position, the calculation unit 112 determines whether portion dimension values of the elevator shaft calculated based on the first reference core position satisfy a predetermined specification.

Abstract: A refill for staples, which can not be removed from a cartridge unless all sheet-type connected staples in a stapler body are delivered. A refill for staples is installed in a detachable manner in a stapler body, and includes a refill body which holds the sheet-type connected staples, and a pressing member which presses the sheet-type connected staples. A delivery port delivering the sheet-type connected staples and a locking plate provided with a locking section which locks a locked section in the stapler body are formed in the refill body. When the sheet-type connected staples are pressed, the pressing member is engaged with the locking plate not to allow rotation of the locking plate, and, when the sheet-type connected staples are not pressed, the pressing member is disengaged from the locking plate to allow rotation of the locking plate. Thereby, the locking section of the locking plate can be removed from the locked section in the stapler body.
