Abstract: A content delivery system and content delivery method allow data or files acquired by delivery to be replayed multiple times on each terminal without redelivery and can prohibit replay by people without permission. Included are the steps of determining, when predetermined information is input from the terminal 14A, whether the information is identical to predetermined member information, and of receiving a request, via a predetermined application 20A of the terminal 14A, and delivering content by streaming to the terminal 14A when the information input from the terminal 14A is identical to the member information.

Abstract: A ball throwing machine includes a ball throwing mechanism that is mounted on a frame that rotates about a vertical axis so that balls are ejected at preset positions along an arc. In a preferred embodiment, the ball throwing mechanism is mounted on a base plate that rotates back and forth through a 90-degree arc. A timing plate controls the rotation of the throwing mechanism and includes projections that trigger the ejection of the balls at preselected angular positions.
