JP2005040550A - Book rest for soft and rectangular back type book - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a book rest preventing the paper face of an optionally opened page from returning to an original state by holding slight partial areas of a cover and a back cover of a book from both sides to compensate for such a defect of the rectangular back type book that many of the rectangular back type book of A5 size or larger stand still in a readable state when turning the pages around the middle and letting go the hold but the paper faces of pages close to the beginning and the end mostly return to the original state when letting go the hold even if pressing them hard by hand. <P>SOLUTION: A portion with shallow depth in an edge direction from the back of a soft and rectangular back type book is held and lightly fixed by two sliding blades, and either one of the blades is slightly moved by a screw or a cam and pressed hard to complete setting, thus permitting reading of the optional page. After reading, the screw or cam is slightly loosened for easy detachment. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

Detailed Description of the Invention

  The present invention relates to a pedestal intended for a book whose paper surface is stationary in a state where it can be read without being held down by a hand when a page close to the middle is opened with a square cover of a soft cover.

  As a method of preventing the open paper surface from returning to its original state, the conventional stand has a method of mechanically pressing the paper surface and removing the presser and pressing it each time it is turned.

Problems to be solved by the invention

There are many cases where the corners of a soft cover turn back when you release the hand after turning the page of the page near the beginning or end.
The conventional method of pressing a part of the opened paper using a presser is time-consuming and troublesome, such as removing the presser by hand for each page and pressing it again.

Means for solving the problem

  In order to make the present invention easier to understand, for example, when a corner book is inserted shallowly about 10 mm in depth from the back to the fore edge in a vise “grip face” and tightened and the page close to the cover is turned, the paper surface is hardly restored, Stand still in the open state. The present invention applies this principle and solves the above-mentioned problems by providing a stand that is small, safe and can be set quickly, and that an arbitrarily opened paper surface can always be read without bothering hands.

  As a representative pedestal of the present invention, as shown in FIG. 2 and FIG. 3, a square spine is inserted between a blade 4 that slides on a ratchet and is finely moved on a pedestal base 3. Slide 4 and pinch it lightly. Subsequently, one of the blades 5 is turned by a screw 9 (cam 10 in FIG. 4), and is finely moved and pressed firmly. When the book is opened arbitrarily, the stand will not come off and keep it almost vertical.

The invention's effect

  When a corner book is set on the stand of the present invention and a page near the first or last page is turned as shown in FIG. 2-12, the paper surface remains open and still. There is no hassle of holding it with your hand each time you turn it, or holding it with a weight each time. The type of pedestal illustrated here is often hidden under the book and invisible to the reader.
