【Example】

 A description will be given below with reference to the drawings. The substrate 10 for receiving the book B is composed of a back support part 1 for arranging the back part, and wing plates 2 and 3 located on the left and right of the back support part 1 for keeping the book B open (see FIG. 2).

The back support portion 1 is provided in the central portion of the substrate 10 by being recessed in a substantially U-shape, and the size is set based on the tallest one of the assumed size of the book B, and the upper and lower sides thereof are set. Is provided with a pair of engaging pieces 4 and 5 (FIGS. 5 and 6). The engaging pieces 4 and 5 are fixed by adhesion or the like in the grooves formed inside the protruding strips 13 and 14 that can come into contact with the upper and lower ends of the binding portion of the book B, and are arranged to face each other.

Among these, the lower protruding piece 14 can support the binding portion and bear a part of the load of the book B. On the other hand, the upper protrusion 13 is attached to the base plate 10 so as to be vertically movable along the guide groove 11 provided in the up-down direction of the back support part 1, and is a stopper made of screws that penetrate the guide groove 11. It is normally in a loose fitting state by 12 and is fixed at a position corresponding to the height of the book B (FIGS. 5 and 7).

The wing plates 2 and 3 are portions for supporting the front and back covers of the book B and the opened text page, respectively, whereas the backrest portion 1 assumes a tall book B. If anything, the size of the book B is determined based on the small book B, and the book B of a larger size can be handled by adjusting the movement of the holding pieces 6 and 7, which will be described later. As a result, the substrate 10 as a whole has a unique shape in which the upper portion of the back support portion 1 projects (FIG. 2).

The holding pieces 6 and 7 are attached to the left and right ends of the blades 2 and 3 via the elastic members 15 and 16 in order to hold the body page of the open book B. The expansion / contraction members 15 and 16 are provided to correspond to the size of the book, and these are slidably and loosely inserted into the guide grooves 25 and 26 formed in the left and right directions of the blade portions 2 and 3, respectively. The book B is fixed to a position suitable for the size of the book B by a stopper 28 screwed from the rear surface to the elastic members 15 and 16 through a long groove 27 formed in the groove bottom in the left-right direction.

Reference numeral 29 denotes a support shaft that rotatably supports the holding pieces 6 and 7 on the outer ends of the elastic members 15 and 16, respectively. Each of the holding pieces 6 and 7 rises from the shaft fulcrum and is formed in a curved or substantially L-shape bent toward the center in the front surface of the substrate (FIG. 8). A tension force is applied by a spring 30 at a portion above the shaft fulcrum, The one end of the pinch is configured to elastically press the text page. Since the spring 30 is provided between each member 15 and 16 and the holding pieces 6 and 7, the holding force is always constant.

When the book B is set on the substrate 10, roller shafts 8 and 9 for pressing the left and right sides of the text page and turning the pages are attached to the tip ends of the respective holding pieces 6 and 7. Each of the roller shafts 8 and 9 is rotatably supported by a plurality of shaft-supporting projections 31, 32 and 33 provided at the tip of the gripping piece, and friction rollers 17 and 18 are provided so as to come into contact with the text page at least at two positions. They are provided on the shaft at intervals (Fig. 9).

The rollers 17 and 18 are formed by a metal boss 34 fixed to the roller shafts 8 and 9, and a friction ring 35 made of a rubber or other friction material fixed to the outer periphery of the metal boss 34. It is rotated by the knob 19. The friction wheel may have a so-called knurling type friction structure in which a large number of axial irregularities are formed on the circumferential surface, and it is not necessary to rely only on a material such as rubber. The page turning torque can be freely set by the material, structure and diameter.

Clips 23 and 24 are integrally or separately provided on the left and right sides of the lower side of the substrate 10 (FIGS. 1 to 4). The clips 23 and 24 can hold the hard cover of the book B or, in the case of a soft cover, the cover and several pages of the text.

The substrate 10 is set at a desired position by the arm 21 of the base 20 at the mounting portion on the back surface. The attachment portion has direction adjusting means 22 composed of a vertical support shaft 36 and a horizontal support shaft 37 of the book B (FIG. 10).

The arm 21 has a length and a curved shape extending from above the head of a supine user to a required front position, and is connected to the base 20 at the other end. The base 20 can be changed according to the use condition, but in the case of the embodiment, it has a stand base 38 and a locking portion 39, and is suitable for use in a bed. A swing light 40 can be provided at an appropriate position on the base 20 to illuminate the text page. 41 indicates the switch.

In the book stand of the present invention thus configured, the book B is opened on the front surface of the substrate 10, and the left and right covers are sandwiched between the clips 23 and 24, while the back part has the lower end. Engage with the lower engaging piece, slide the upper engaging piece 4 into the upper end to engage and fix it, open the holding pieces 6, 7 to contact the text page from the left and right of the book, and hold the holding piece 6, Fix the position 7 at an appropriate position corresponding to the size of the book.

As shown in FIG. 9, the book set on the reading table is facing downward, but the load is lower than the upper and lower engaging pieces 5 and 4, the left and right holding pieces 6 and 7, and the clip 23. , 24. At this time, the engaging pieces 4 and 5 in the center press the back of the book B against the backrest portion 1, so that the book is stable, and the left and right holding pieces 6 and 7 are two rollers provided on the roller shafts 8 and 9, respectively. Since it is pressed linearly in the vertical direction by 17, 18, there is no risk of the page hanging. It should be noted that it is easy to expand and contract the interval between each of the two rollers 17 and 18 to further comply with the size of the book.

In particular, in the upper engaging piece 4 supporting the upper end of the center of the book B, when the screw 12 is loosely fixed, the projecting piece 13 inclines by the load of the book B, and at the corner Q of the upper engaging piece 4, At the same time as the contact is made, the corner P of the screw head also contacts the lower surface of the back support part 1, so that the frictional force is generated by the biting of these both angles P and Q. Therefore, the protruding piece 13 integrated with the upper engaging piece 4 is fixed at a predetermined position as if the free hook were stopped at an arbitrary height.

One of the roller shafts 8 and 9 is rotated to turn over the page during reading, but in the case of the vertical writing B, as shown in FIG. 1, the right roller shaft 9 is rotated to the right to repeat the page. Then, it is inserted into the rollers 17 and 18 of the left roller shaft 8 by hand, and the left roller shaft 8 is rotated counterclockwise so as to take slack. In the case of horizontal writing, the above operation is reversed. Thus, according to the present invention, the page is effectively stopped almost in the free state.
