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 bound collection of leaves having a spine and a method of its manufacture are disclosed. Each leaf of a first plurality of leaves of the bound collection includes a first pattern of tabs by which that leaf is bound. The tabs of the first pattern are distributed along a binding axis of that leaf that is parallel to a spine axis of the spine. Each leaf of a second plurality of leaves of the bound collection includes a second pattern of tabs different than the first pattern by which that leaf is bound. The tabs of the second pattern are distributed along a binding axis of that leaf that is parallel to the spine axis. Each tab of the first pattern and second pattern of tabs extends in a direction orthogonal to the binding axis from within an unbound region to a binding-side edge of that leaf.

A pen holder for engaging a spiral coil of a notebook includes a planar body sized to be inserted into the spiral coil of the notebook having first and second straight edges, a series of slotted perforations defined along the first straight edge and configured to mesh with the spiral coil of the notebook, and a plurality of horizontal slots arranged in a column parallel with the series of slotted perforations and configured to engage a clip of a writing instrument.

A sheet stacking device includes a vacuum system that delivers an individual sheet toward a binder element, a sheet deflector element that presses an end of the individual sheet onto the binder element, and a sheet kick-down element that presses the individual sheet away from the vacuum system.

A tab is provided for notebooks and binders. The tab is placed within the space otherwise occupied by a binding, and thus is protected from wear and does not appreciably increase the overall size of the notebook or binder. The tab may be located at a corner of the binding or at an intermediate point along the binding.

The present invention relates to a multi-purpose three-dimensional object intended to be applied in a three-dimensional form by applying a planar object composed of a pattern portion and a base portion to various uses. That is, the multi-purpose three-dimensional object of the present invention comprises: a plate-shaped pattern portion (2) having a pattern image (21) in which the image is expressed so as to be visually noticed, and a base portion (3) coupled to one side of the pattern portion (2). According to the present invention, by the addition of various functions and design elements to the pattern portion (2), there is an advantage of being used as a three-dimensional interior decoration means or as an educational means for infants.
