Abstract: Advertisements of commodity or service of companies and stores are not easily delivered to customers and readers. Even when the advertisements are delivered with difficulty, the advertisements are lost or discarded without being stored for a long period. Thus, the advertisements are hardly memorized. When conventional four types of mass communication are used, cost effectiveness is poor. When an Internet media is used, it is difficult to attract an attention. Thus, advertising technology capable of exposing individual advertising material while being connected with printing medium and Internet medium is required to cause an action. Calendar numbers are regarded as an advertising medium, advertisements and a calendar are printed integrally on both sides of pages and published.

Abstract: The present invention provides a delivery system for easily collecting/notifying a store/business opening day, anniversary day, or store/business closing day of a company, store and other organizations. In the delivery system, a server accepts, from a sponsor-side communication device, date information regarding any of the store/business opening day and the anniversary day, and an event information of the memorial day. The server calculates the information of the anniversary day for the next and subsequent years based on the date of the store/business opening day. For the store opening day registered in the server by a person opening a new store, the anniversary day is registered by the server, and the registered day is updated for the next and subsequent years when the anniversary day of an existing store is registered. The server accepts the transmission of a keyword from a user-side communication device and searches for a sponsor.

Abstract: A file binder 103 has a back side plate member 2, a projecting member 3, and a front side plate member 6. A lower end part 5 of the back side plate member 2 is bent forward. The projecting member 3 projects forward from a part of the back side plate member 2 higher than the lower end part 5. The front side plate member 6 extends downward from a front end part of the projecting member 3 beyond a front end edge 80 of the lower end part 5, and forms a gap 81 from the front end edge 80. Pillar shape protruding portions 15 protrude backward from the front side plate member 6 under a lowermost end of the back side plate member 2, and beyond the front end edge 80, and reach the substantially same plane as a back surface of a main body part 4 of the back side plate member 2.

Abstract: A desk leaf base has a base formed of a trapezoidal tubular body in a trapezoidal shape in a side view, closed from a bottom surface to a certain height in both sides, and opened in an upper portion therefrom. An inclined front wall of the tubular body is removed from one side to the other side, in a range from the height to a higher height lower than a top surface. A binder mounted along an elongated top surface of the base has an elongated body and rings. The elongated body is mounted along the top surface of the base with an approximately same width as the top surface. The rings are mounted on the body and capable of opening and closing. Each ring includes linear portions that protrude from the body inclining upward on front and back sides when closing.

Abstract: Tear-off perforations 3 are formed vertically and horizontally at a rectangular sheet 1 so as to divide the entire sheet 1 into sixteen equal rectangular leaves 5. The sixteen leaves 5 are provided with binding holes 7 at two corresponding places along one side corresponding to one another. The sixteen leaves 5 have the front surfaces printed in an identical attitude relative to the one corresponding side. Monthly tables of January to December of a prescribed year and monthly tables of January to March of the following year are printed on fifteen leaves out of the sixteen leaves 5. Thus, the manufacturing costs of the printed plurality of leaves can be reduced.

Abstract: A desk leaf base includes a base and a binder. The base is formed of a trapezoidal tubular body that is formed in a trapezoidal shape in a side view, closed from a bottom surface to a certain height in both sides, and opened in an upper portion therefrom. An inclined front wall of the tubular body is removed from one side to the other side, in a range from the certain height to a height higher than the certain height and lower than a top surface. The binder is mounted along an elongated top surface of the base, and includes an elongated body and a plurality of rings. The elongated body is mounted along the top surface of the base with an approximately same width as the top surface. The plurality of rings are mounted on the body and capable of opening and closing. Each of the plurality of rings includes linear portions that protrude from the body so as to extend inclining upward on front and back sides when closing. Accordingly, the desk leaf base which allows the leaf group to easily be replaced is achieved.
