Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a book placement device, and particularly to a book placement device that is used to read the contents of a book while automatically changing the pages of the book. Regarding equipment.

[Prior Art] With the recent development of optical character reading devices, it is now possible to automatically read the contents of books, for example, to read them to blind people or young children, or to read the vast amount of information stored in books to optical discs, etc. There is a lot of research being done on how to store data in a compact manner.

As shown in FIG. 4A, the conventional book placement device for automatic reading is designed to place a book in an open state on a flat surface 1, and to read the book one by one while changing pages. The contents of the book were automatically read by an optical character reading device or the like placed above the mounting table 1.

Further, the holding member 3 used to flatten the double-page spread of the book is made of a transparent plate made of a flat plate, and is designed to move the mounting table 1 upward each time a page is changed so that it comes into contact with the double-page spread of the book. I was getting used to it.

[Problems to be Solved by the Invention] However, in this conventional book placement device, since the surface 1a of the placement table 1 is flat, when the book is set on that surface, the book tends to shift horizontally and vertically, making positioning difficult. There was a drawback that it could not be done easily.

Also, when the flat holding member is brought into contact with the facing side of a book, if the left and right halves of the book have different thicknesses, only the thicker left or right half will be pressed, as shown in Figure 4B. This made it difficult to press the thinner left or right half flat, making it difficult to focus on the page when reading a book, which caused problems.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to make it easier to set a book in a predetermined position, and to make it possible to hold the entire double-page spread of the book flat.

[Means for Solving the Problems] For this reason, the present invention includes a book mounting table 1 and a pressing member 3 for pressing the double-page spread of the book placed on the mounting table 1.
A book mounting device having a surface 11a of the first mounting table 11 on which the left half of the double-page spread of the book is placed, and a second mounting table on which the right half of the double-page spread of the book is placed. 12 surfaces 12a are arranged to be inclined at a predetermined angle θ, and the first and second surfaces 12a are
A coil spring 45 and an auxiliary coil spring 46 are provided at the lower part of the placing tables 11 and 12, respectively, and each is independently movable in the vertical direction with respect to the book placing surface. One end is connected to the mounting table 11, the other end is connected to the second mounting table 12, and the central part 47
A has a connecting member 47 pivotally attached to the base 2, and the first mounting table 11 and the second mounting table 12 are relatively movable in the vertical direction.

[Function] In the present invention configured as described above, when the presser member is brought into contact with the double-page spread of the book, the first mounting table and the second mounting table are arranged so that the entire double-page spread of the book contacts the presser member flatly. Each of the mounting tables moves freely in the vertical direction.

Further, since the surface of the first mounting table on which the book is placed and the angle formed by the second mounting table have a predetermined angle, the book is set so that the spine of the book is always in a fixed position.

[Examples] Examples of the present invention will be described below based on the drawings. FIG. 1 is a perspective view showing the entire book placement device according to the present invention.

In FIG. 1, a book table 1 is mounted on a base 2, and a presser member 3 is placed above the book table 1. As shown in FIG.

This book mounting table 1 is divided into a first mounting table 11 on which the left half of the double-page spread of the book is placed, and a second mounting table 12 on which the right half of the double-page spread of the book is placed. 1 and 2nd respective mounting tables 11, 1
2 is attached to the base 2 so as to be movable in the direction perpendicular to the book mounting surface.

This mounting table 1 is a first mounting table 1 on which a book can be placed.
The angle θ between the surface 11a of the first mounting table 1 and the surface 12a of the second mounting table 12 has a predetermined angle, and the total surface of the surfaces 11a and 12a of the first and second mounting tables 11 and 12 is V. One edge 11b of the surface 11a of the first mounting table 11 is in contact with one edge 12b of the surface 12a of the second mounting table 12.

Further, the base 2 is supported by a guide rail 22 that can freely move up and down along a sliding hole 21a formed in the support member 21, and the front part 2a of the base 2
When you pull the handle 23 attached to the guide rail 2
The base 2 is pulled out forward by rolling on top of the base 2.

On the other hand, the holding member 3 is attached to the first and second mounting tables 1.
The housing is made up of a chevron-shaped transparent plate with its central part protruding so as to come into contact with the entire surface including surfaces 11a and 12a of Nos. 1 and 12, and in which mechanical parts such as an optical character reading device (not shown) are housed. It is fitted into the bottom of the body 31.

The housing 31 into which the presser member 3 is fitted is fixed to the support member 21.

FIG. 2 is a perspective view of the first and second mounting tables 11 and 12 attached to the base 2. FIG.

In FIG. 2, front and rear letter-shaped locking plates 40a and 40b are fixed on the base 2. As shown in FIG.

In addition, two support shafts 41a, 41b extend vertically from the bottom surfaces of the first and second mounting tables 11, 12.
are provided in a protruding manner, and a guide column 42 is horizontally suspended between the support shafts 41a and 41b.

This guide column 42 is a locking plate 4 attached to the base 2.
It is sandwiched from both sides by 0a and 40b, and its movement is restricted.

Moreover, this guide column 42 and the locking plates 40a, 40b
are pivotally supported by guide shafts 43a, 43b passing through both the guide column 42 and the locking plates 40a, 40b.

A holding shaft 44 projects from the center of the guide column 42 toward the base 2 and is inserted into a holding hole 44a formed in the base 2. A coil spring 45 is wound around this holding shaft 44 .

Further, auxiliary coil springs 46a, 46b are wound around the support shafts 41a, 41b.

In such a configuration, a guide shaft 43 that passes through both the guide column 42 and the locking plates 40a and 40b
The guide column 42, which is pivotally supported by the guide pillars 40a and 43b, is movable in the vertical direction without any horizontal movement, and the range of vertical movement is limited by the locking plates 40a and 40b. It's getting old.

Further, the guide column 42 is urged upward by the coil spring 45 wound around the holding shaft 44, and the guide column 42 and the Since the space between the first and second mounting tables is biased to be wider, the first and second mounting tables are subjected to an upward force without any external force being applied. working, 1st and 2nd
The mounting tables 11 and 12 are pushed upward by locking plates 40a and 40b within a limited vertical movement range.

In this case, the first mounting table 11 and the second mounting table 12 are connected using the connecting member 47, and when the first mounting table 11 moves upward, the second mounting table 12 is moved downward. When the first mounting table 11 moves downward, it is preferable to move the second mounting table 12 upward.

Therefore, the center portion 47a of the connecting member 47 is connected to the base 2.
A guide in which one end of the connecting member 47 is pivotally connected to a guide column 42 which is horizontally suspended on the first mounting table 11, and the other end of the connecting member 47 is horizontally suspended on the second mounting table 12. It can also be pivoted to the pillar 42.

As a result, when the facing side of the book placed on the mounting table 1 is brought into contact with the holding member 3, the first mounting table 1
The first and second mounting tables 11 and 12 are moved relative to each other in the vertical direction so that the force acting on the second mounting table 1 becomes the same as the force acting on the second mounting table 12.

Next, the operation of the book placement device constructed as described above will be explained with reference to the operational diagram shown in FIG.

As shown in FIG. 3A, when a book is placed on the mounting table 1 but the presser member is not pressing the double-page spread of the book, the first and second mounting tables are

Due to the force relationship with the biasing force of the auxiliary coil spring 46 wound around the
The upper and lower positions of 2 are determined.

Here, as shown in FIG. 3B, the guide rail 22 is moved upward along the sliding hole 21a formed in the support member 21 so that the facing side of the book comes into contact with the presser member 3. The first and second mounting tables move relatively in the vertical direction, so that the left half spread surface and the right half spread surface of the book spread come into contact with the presser member 3, respectively. Furthermore, in the present application, a detection mechanism is provided at an appropriate position to detect the thickness of the left half of the book's spread and the thickness of the right half of the book's spread. It is also possible to provide a mechanism that automatically adjusts the heights of the first and second mounting tables based on the information.

[Effect] As explained above, according to the present invention, since the surface of the first mounting table on which the book is placed and the surface of the second mounting table have a predetermined angle, when setting the book, This has the effect of making it difficult for books to be set diagonally and preventing them from shifting in the left and right directions.

In addition, the mounting table is separated into a first and a second mounting table, and each of the mounting tables is configured to be relatively movable by a connecting member, so that the right half and left half of the book are separated. The position of the book does not shift even when the amount is different, the two-page spread surface can always be kept at the same height, and unnecessary force is not applied to the binding margin so that it is not damaged.

Furthermore, since the first and second mounting tables are configured to be able to move slightly in the vertical direction using coil springs and auxiliary coil springs, the coil springs work even if the number of pages in the left half and the right half differ slightly. The double-page spread can always be kept at a constant height.

As a result, the double-page spread surface of the book becomes flat, which has the effect of making it easy to focus on the double-page spread surface even when reading the contents of the book automatically.
