It had been.

[Problems to be solved by the device]

However, in the conventional book stand, since the lower end of the supporting column 4 is inserted into the sliding groove 6, when the book is clamped from both sides, a moment acts around the lower end of the supporting column 4 to support the supporting column 4 of the support fitting. There is a problem that looseness may occur between the lower end of the slide and the sliding groove 6, and both hands are often used for the work of handling the book, and the operability is poor.

In addition, when trying to take out a favorite book out of the books that are leaned against the book stand, it is usually pulled out forward, but if the upper space of the book that is leaned is narrow and it is difficult to insert a finger, It wasn't easy to get right away, and this sometimes messed up the book.

Furthermore, for large and heavy books such as A4 size and B4 size maps, there is a problem that the support metal fitting 3 is structurally weak and difficult to be pinched against the support metal fittings 3,3. .

The present invention has been made to solve such a problem, and a pair of movable bookends and driven bookends facing each other and a fixed bookend fixed to the frame are erected on the frame, and the driven bookends are set up. The purpose of the present invention is to provide a book stand that allows a large and heavy book to be efficiently leaned up and taken out with one hand even by using a drive mechanism that moves a sliding book end by tensioning a spring between the frame and the frame. There is.

[Means for Solving the Problems]

Therefore, in the book stand of the present invention, a sliding book end and a driven book end standing upright against the frame of the book stand, a fixed book end fixed to the frame, and a tension between the driven book end and the frame are attached. It is equipped with a spring and a drive mechanism for moving the moving book end onto the frame.

[Action]

The book stand of the present invention is configured as described above, and when the book is to be taken in and out during use, first the drive mechanism is operated to move the moving book end to the right, and the driven book facing the opposite side. Move away from the end side,
Due to the elastic force of the spring, the book tilts and works so that it can be easily taken in and out.

Next, when you try to sandwich the book in the book stand after inserting or removing the book, you can move it by operating the drive mechanism with the book between the driven bookend on the left side and the moving bookend on the right side. Move the book end to the left to work as if the book were pinched by the book stand.

Furthermore, when the moving book end is moved to the left by the drive mechanism when there is no book in the book stand, it works so as to stop at a position before the fixed book end.

In this way, it works so that even a heavy and large book can be put in and taken out from the book stand with one hand.

A) The operation of putting a book in and out of the bookcase will be described.

When the moving book end 12 is moved to the right by inserting the plug P into an outlet not shown and moving the switch S to the right, the restoring force of the spring 16 causes the driven book end 13 to move slightly to the right. When it becomes easy to take in and out due to the inclination and the clearance, the moving book end 12 can be stopped at a desired position by releasing the hand from the switch S.

Next, when the book S is put in and out and the switch S is moved to the left side, the book between the book ends 12 and 13 is pinched, and the driven book end 13 is gradually moved to the left with the book.
As the spring 16 approaches the fixed bracket 11 against the resilience, the motor 20 is stopped by contacting the switch S3, and the book is sandwiched between the brackets 12 and 13. In this way, it is understood that the book is clamped between the book ends 12 and 13 while being pinched by the action of the elastic force of the spring 16 so as not to rattle.

(B) The operation of inserting a book when there is no book in the bookcase will be described.

In this state, since no book is inserted, the driven book end 13 is set to the initial position A ₀ by the spring 16.

Now, by inserting the plug P into an outlet (not shown) and turning the switch S to the right, the moving bookend 12
Moves to the right, stops the motor 20 by contacting the switch S1, and when it is in the right limit C of the operating range L1, the book is placed between both hook ends 12 and 13, and the switch S is on the left side. As a result, the moving book end 12 is moved leftward, and the driven book end 13 is moved leftward against the elastic force of the spring 16 through the book. In the left limit A of L2, the motor 20 comes into contact with the switch S3.
Stop and pinch the book between both book ends 12 and 13.

In this way, even a heavy and large book works so that it can be taken in and out of the book stand with only one hand.
