Abstract
A device is provided for writing in the dark which has the external appearance of a book. Inside the book, a box is attached to the inside of one of the covers. The box contains a continuous strip paper supply which is drawn from underneath an illuminated translucent panel through channels that lead the paper over the translucent panel and under a lid which guides the paper across the pane so that the paper may be drawn out from the box. The lid has an opening through which the user may write on the paper. When in use, the box provides sufficient light so that the user can see to write on the paper yet does not provide so much light that others attempting to sleep nearby are disturbed. The covers may be folded over the box to give the device the appearance of a book.
Claims19
A device for writing in the dark, comprising:
- a casing that is light-tight except for an opening formed in the casing;
- illumination means mounted within the casing, the casing being adapted to allow light to emerge from the opening in the casing;
- paper supply means for a continuous strip of paper located underneath the illumination means within the casing;
- and
- channel means for directing the continuous strip of paper from the paper supply means to and over the illumination means so that a user can write on a portion of the continuous strip of paper illuminated by the illumination means.
A device for writing in the dark, comprising:
- an open-faced box having a bottom and sides that define a first cavity;
- illumination means adapted to be placed within the first cavity;
- spacer means for separating the illumination means from the bottom of the box so that the box and illumination means define a second cavity that is a portion of the first cavity and is sized to contain and store a folded continuous strip of paper;
- a lid detachably fastened to the box, the lid having an opening which is congruent with a substantial portion of the illumination means when the lid is fastened to the box and overlapping the box so that light cannot escape from the illumination means except through the opening;
- a translucent pane which fits over the illumination means and under substantially all of the opening in the lid;
- and
- a first channel provided between the illumination means and the sides of the box to permit a continuous strip of paper stored in the second cavity to be drawn through the first channel and over the translucent pane under the opening in the lid.
A device for writing in the dark, comprising:
- a rectangular open-faced box having a bottom and four sides that define a first cavity having the general form of a rectangular parallelopiped;
- a rectangular lid hingeably attached to the box so that the lid can be rotated away from the box to expose the first cavity or rotated against the box to cover the first cavity, the lid being formed and adapted to fit into place over the first cavity so as to prohibit the exit of light from within the first cavity except through a rectangular window formed in the lid;
- a rectangular illumination tray sized and adapted to be placed within the first cavity substantially underneath the window in the lid when the lid covers the first cavity, and spaced from the bottom of the box by spacer means interposed between the bottom of the box and the illumination tray thereby to form a second cavity defined by the illumination tray and the bottom and sides of the box, the second cavity having the general form of a thin rectangular parallelopiped and sized and adapted to hold and store a supply of a folded continuous strip of paper;
- electric illumination means mounted in the illumination tray;
- a translucent panel detachably mounted on the illumination tray and between the illumination tray and the window of the lid when the lid is in place on the box covering the first cavity so that the light emitted from the electric illumination means in the illumination tray passes through the translucent panel and thence through the window in the lid;
- a first channel formed between the box and the lid to permit the continuous strip of paper to be drawn from the second cavity to above the illumination means and thence between the lid and the translucent panel so that the continuous strip of paper may be drawn between the translucent panel and the window for the user of the device to write on the paper strip;
- and
- second channel means formed in the lid or between the lid and the box permitting egress of the paper and allowing the paper strip to be drawn from the device and a portion thereof torn off.
