In some embodiments, an array of printed information sheets to be placed in a business establishment may include at least two stacks of printed information sheets being detachably connected to each other. Each stack of printed information sheets may include at least a first multiple product information sheet and a second information sheet that are removably attached to each other or to the stack. The first multiple product information sheet may have printed thereon first product information about a first product to be displayed in the business establishment and a first location indicator indicating a first predetermined location in the business establishment where the first multiple product information sheet is to be displayed. The second multiple product information sheet may have printed thereon second product information and a second location indicator.

An image forming apparatus includes: a first apparatus configured to perform punching on a sheet by using a punching member; a second apparatus, including a stacking part on which a plurality of sheets punched by the first apparatus is stacked, and configured to perform binding so as to obtain a bookbinding article in which a binding member penetrates in a ring shape through punched holes of the plurality of sheets; a notification unit notifying information; and a control unit configured, in a case of starting a job using the first apparatus and the second apparatus and determining that a jam has occurred in the stacking part, to cancel the job, and to cause the notification unit to notify that a thickness of a sheet stack stacked on the stacking part exceeds a thickness that enables to be bound by the binding member used by the second apparatus.

A binding component holding sheet is configured to detachably hold a binding component obtained by spirally winding a wire rod and includes a holder configured to hold the binding component by insertion of a circumferential portion of the spirally wound binding component. The holder is configured to hold the binding component so that an area greater than a half of the binding component in a circumferential direction protrudes to one side of the binding component holding sheet and an area less than the half of the binding component in the circumferential direction protrudes to the other side of the binding component holding sheet.

A sheet system including a sheet having an edge and at least one generally triangular hole positioned adjacent to but spaced apart from the edge. A side of the triangle is oriented generally parallel with the edge of the sheet.

A book binding apparatus includes: a first processing section which is configured to perform a first process on a medium; a second processing section which is configured to perform a second process on the medium on which the first processing section has performed the first process; a first discharging section to which the medium on which the first processing section has performed the first process is discharged; and a second discharging section to which the medium on which the first processing section has performed the first process, and on which the second processing section has performed the second process is discharged.

A photoluminescent writing pad, wherein a) the writing pad is fastened to a back cover of a notebook and arranged to be turned to a writing pad of a page of the notebook, b) the writing pad is arranged to gleam through a writing page thus enabling reading and writing in darkness and c) the writing pad has notches for accommodating a spiral wire, especially spiral or wire or similar binding, of a notebook for securing the writing pad under the page of the notebook to function as an interleaf.

A book has a front cover having a first edge which is unconnected, and an opposing second edge which is connected to a spine. A back cover has first edge which is connected to the spine and an opposing second edge which is connected to flexible joint or fold-line. The book has a third cover having a first edge which is connected to the flexible joint, that couples the third cover to the back cover, and an opposing second edge which is connected to binding. The front cover is configured to fold back about the spine to retain the third cover proximal the second edge of the third cover to retain the book in a propped-up position for reading. A page holder slides along the left and right sides of the third cover and has an opening that allows a page to be pushed therethrough.
