Description

{Apparatus for turning page automatically}

The present invention relates to a page turning device, and more particularly, to have a relatively simple configuration to reduce the failure rate while allowing each component to operate smoothly with each other organically, so that the page can be automatically flipped. It is about page turning device.

For the general public, it is natural and very convenient to read a book while holding a book in one hand and using the other hand to turn pages. However, even in this extremely general posture, it will never be easy for the physically handicapped person who cannot use both hands smoothly.

However, even if you are not a person with physical disabilities, if a piano player plays the piano, you cannot perform the performance of the piano and handing over the score at the same time. Therefore, when playing the piano, an additional assistant player stands beside the piano and takes over the sheet music at an appropriate time.

As such, despite the fact that turning pages is very easy, there is a great need for automatically turning pages according to people, places, and environments. In response to this need, a technology has been developed for automatically turning pages.

In Publication No. 10-1999-000763, a page turning device is known for automatically turning pages. In the known art, the roller part, the turning bar, the conveying means, the fixed bar, the fixed bar driving means, the switch part, and the control part try to automatically turn the page.

That is, the control unit drives the rotating roller and the turning bar lifting motor at a predetermined speed so that the turning bar is inserted into the space between the bookshelves, and then the conveying bar is driven into the space between the bookshelves. Drive the motor to rotate the transfer belt to which the transfer bar is connected to the left.

When the transfer bar moves to the fixed bar side according to the rotation of the conveying belt, the teeth formed on the rotary teeth and the teeth formed on the rotating plate gear are engaged so that the shaft is rotated so that the fixed bar rotates to be perpendicular to the support. Is passed.

When the page turning process is finished, the controller drives the turning bar lifting motor so that the turning bar is lowered again and reversely rotates the conveying belt driving motor so that the turning bar and the conveying belt are returned to their original positions. At this time, the rotation of the rotating plate gear engaged with the rotary teeth by the movement of the transfer belt reverse rotation, the shaft is rotated reversely, the fixed bar is moved back to the book position.

By the way, in the known prior art, there are substantially many components employed for turning pages. Thus, if they work organically, it may seem easy to turn the page, but it is not easy to apply it in practice, and due to the complicated configuration, the failure rate is high.

Accordingly, the present applicant has developed a one-page automatic page turning device to have a relatively simple configuration to reduce the failure rate, and to operate the components smoothly with each other organically, so that the pages can be automatically and smoothly turned over.

According to the applicant's automatic page turning device, it can be very useful for those who want to read a book in a comfortable state, including a player who needs to play with both hands as well as a physically handicapped person who cannot use both hands.

The present invention was devised to solve the above problems, and the object of the present invention is to reduce the incidence of failures by having a relatively simple configuration, while the components operate smoothly with each other organically and smoothly. It's about providing a one-page automatic page feeder for turning.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a perspective view of a page turning device according to the present invention, Figure 2 is a perspective view of the operating state of FIG.

As shown in these figures, the page turning apparatus 1 according to the present invention includes a book supporting portion 10 for supporting a book, and a plurality of iron pieces fitted to lower edges of both sides of each page P of the book. A holder 40 having a drive motor 30 that can be rotated forward and backward, an electromagnet piece 43a that is magnetically coupled to and decoupled from the iron piece 20, and a page coupled to the holder 40. Rotational movement of the turning bar 50 passing through the rotational force of the driving motor 30 is interposed between the turning bar 50 and the driving motor 30 and the turning bar 50 which are rotatable in a direction in which P is passed and the opposite direction. And a rotation assembly (60) for converting the power, a power supply unit (70) for selectively supplying power to the driving motor (30) and the electromagnet piece (43a), and a controller (80a).

The book support part 10 corresponds to the body of the page automatic page turning device 1 as a part supporting the book. The book support portion 10, according to the position, the body portion 12 and the lower support portion 14 protruding along the horizontal direction in the direction in which the book is gripped from the plate surface of the body portion 12 to support the bottom of the book Has The body portion 12 is again composed of a horizontal plate 12a on which the drive motor 30 is placed, and a vertical plate 12b erected relative to the horizontal plate 12a.

At this time, the body portion 12 is a plate-like body so as to partially expose the drive motor 30, the holder 40, the turning bar 50, the rotation assembly 60 and the power supply 70 described above. Or a common body (not shown) capable of accommodating all of them.

In the case of the former platelet, it is advantageous to use this automatic page turning device 1 on a piano (see FIG. 5) or the like, and in the latter case, it may be used for reading.

As shown in FIG. 3, the iron piece 20 is manufactured separately and selectively fitted to both bottom edges of the page P. As shown in FIG. At this time, the shape of the iron piece 20 may be a rectangular shape, or may be a triangular shape, as shown in Figs.

The iron piece 20 has the polarity of the attraction force that one end of the opening (20a) and both ends of the opening (20a) contact each other so that each corner of the page (P) is inserted. That is, in FIG. 3, if the region 21 on one side has a polarity of (+) and the region 22 on the other side has a polarity of (−), the page P can be easily inserted therebetween. In addition, it is possible to prevent the iron piece 20 from being randomly separated from the page P. Of course, the iron piece 20 is preferably formed to be relatively thin in thickness and light in weight so as not to be restrained in turning the page P.

As shown in FIG. 4, the holder 40 is mounted on one region of the turn-over bar 50 according to the size of the book while having a stopper 41a formed on one side thereof, and a high intelligence portion. A movable boss portion having a projection portion 42a disposed on the stopper 41a formed in the 41 and arranged side by side with respect to the high intelligence portion 41 to rotate within a predetermined angle range with respect to the high intelligence portion 41 ( 42 and a holder body 43 connected to the movable boss portion 42 and rotatable together with the movable boss portion 42 and on which the electromagnet piece 43a is mounted on the plate surface.

At this time, when the movable boss portion 42 is rotated in one direction with respect to the high intelligence portion 41 in one of the high intelligence portion 41 and the movable boss portion 42, the movable boss portion 42 is rotated. It may be advantageous that a return spring (not shown) is provided for returning to the original position.

Although not shown in detail, the electromagnet piece 43a consists of an electromagnet sheet, an iron core, and a coil. The coil is supplied with power from the power supply unit 70, the path of which is formed in the bracket 64 and through the fixed terminal unit 64a connected to the power supply unit 70, as shown in FIG. 5. It may be provided through an electric wire (not shown) disposed in the turn bar 50 via the movable terminal portion 63a formed in the 63.

As shown in FIG. 1, the electromagnet piece 43a is supplied with power from the power supply unit 70 and is attached to the iron piece 20 inserted into the page P in a state before the page P is turned over.

Then, when the turning bar 50 rotates due to the interaction of the driving motor 30 and the rotation assembly 60, the power from the power supply unit 70 is cut off from the point where the page P is half over. This is a time point when the movable terminal portion 63a formed in the shaft rod 63 falls from the fixed terminal portion 64a to which power is applied, as shown in FIG. 5.

Therefore, when the page P reaches more than half, the electromagnet piece 43a is separated from the iron piece 20 so that the page P can be turned over by its own weight.

If the electromagnet piece 43a is arbitrarily rotated about the axis of the turn-over bar 50 in a state where the power is cut off from the electromagnet piece 43a, the electromagnet piece 43a is turned to work for turning the next page P. It will be difficult to attach to the iron piece 20. Accordingly, in the present invention, the stopper 41a and the projection 42a are formed as a means for preventing the movable boss 42 side from rotating arbitrarily with respect to the high intelligence portion 41.

The rotating assembly 60 is connected to the worm 61 coupled to the rotation shaft 30a of the drive motor 30, the worm gear 62 rotating in engagement with the worm 61, and the worm gear 62. One end of the bar 50 includes a shaft rod 63 is fixed. The shaft rod 63 is fixed to the book holding portion 10 by the bracket 64. On the other hand, it is preferable that a bearing (not shown) is interposed between the shaft rod 63 and the bracket 64 for smooth rotation of the shaft rod 63.

On the other hand, the worm 61 is a rack gear, the worm gear 62 can also be implemented as a pinion, Figure 2 is shown in the accompanying drawings. In particular, when the drive motor and gear assembly structure is changed to only the actuator 100 as described below, the structure and the operability can be improved.

As shown in FIG. 5, the shaft bar 63 is provided with a movable terminal portion 63a which co-rotates with the shaft bar 63 when the turning bar 50 is rotated. The movable terminal portion 63a selectively contacts and releases contact with the fixed terminal portion 64a formed on the bracket 64 in association with the rotation of the shaft rod 63.

Accordingly, when the driving motor 30 rotates in one direction, the worm 61 and the worm gear 62 rotate in turn in association with the driving motor 30. As the shaft bar 63 is rotated by the rotation of the worm gear 62, the turning bar 50 connected to the shaft bar 63 rotates in the direction of FIG. 1 to FIG. 2. On the contrary, when the driving motor 30 rotates in the opposite direction as described above, the turning bar 50 returns from the direction of FIG. 2 to the direction of FIG. 1.

On the other hand, the controller 80a controls the rotational speed and the rotational direction of the drive motor 30 and selectively turns on / off the power provided to the drive motor 30 and the electromagnet piece 43a. Therefore, although not separately shown, it is advantageous to have a plurality of mode switches in the controller 80a to select the above items.

The controller 80a may be a button type and may be integrally coupled to the book support 10, or may be a separate remote control type that can be remotely adjusted as shown in FIG. 1.

The operation of the automatic page turning device 1 will be described with reference to FIGS. 1, 2, and 5 as follows.

First, the iron pieces 20 are respectively inserted in the lower edge of each page P of a book. Then, in the state shown in FIG. 1, the turning bar 50 is disposed in the right region of the book, and the electromagnet piece 43a of the holder 40 is in contact with the iron piece 20.

In the initial state in which the electromagnet piece 43a contacts the iron piece 20 (see "A" in FIG. 5), the movable terminal part 63a formed on the shaft rod 63 is applied with the power supply unit 70 and the connection door power source. Since it is in contact with the fixed terminal portion 64a, power is applied to the electromagnet piece 43a.

In this prepared state, the controller 80a is operated so that predetermined power is provided from the power supply unit 70 to the driving motor 30. When the rotation shaft 30a of the driving motor 30 is rotated in one direction by the power supply unit 70, the worm 61 rotates in conjunction with the worm gear 62 to rotate the worm gear 62.

Then, the shaft bar 63 coupled to the worm gear 62 rotates in the same direction as the worm gear 62 and starts to rotate the turning bar 50 toward the "B" region in the "A" region of FIG. . Until the turning bar 50 reaches the " B " region, the movable terminal portion 63a is continuously in contact with the fixed terminal portion 64a, so that power is supplied to the electromagnet piece 43a continuously. Therefore, the electromagnet piece 43a attracts the iron piece 43a while maintaining contact with the iron piece 20.

When the turning bar 50 continues to rotate and reaches the time when it passes the "B" area, that is, when the page P is over half or more, the fixed terminal portion 64a to which the movable terminal portion 63a is supplied with power. ), The power is cut off to the electromagnet piece (43a).

However, since the page P has already been turned over by half, from this point on, the page P is turned over by the self load of the page P, not the magnetic force caused by the electromagnet piece 43a ("C" in FIG. 5). Reference).

As such, when the power is cut off to the electromagnet piece 43a and the page P reaches the point of time when the page P is crossed by its own load (see “C” in FIG. 5), the driving motor 30 rotates in the opposite direction as described above. Return the turning bar 50 to its original position.

Of course, the turning bar 50 may be configured to move up to the point "D" in FIG. 5, but since the page P is already turned over at the point "C", the turning bar 50 is firmly referred to in FIG. 5. There is no need to move to the D "point. On the other hand, at the point "C", since the projection part 42a is limited by the stopper 41a, the rotation of the movable boss part 42 with respect to the high information part 41 is prevented. As a result, due to the high information portion 41 and the movable boss portion 42, the electromagnet piece 43a can always maintain a constant position.

The movable terminal portion formed on the shaft 63 while the turning bar 50 passes through the "B" point to the "A" point again by the reverse rotation of the drive motor 30 after turning one page P. Since the 63a comes into contact with the fixed terminal portion 64a to which the power supply unit 70 and the connection door power are applied, power is again applied to the electromagnet piece 43a.

When power is applied to the electromagnet piece 43a, the electromagnet piece 43a reaching the "A" point magnetically contacts the iron piece 20 sandwiched on the next page. Then, the drive motor 30 is rotated again in the first direction, the turning bar 50 is the "B" and "C" point at the "A" point of Figure 5 by the organic operation of the rotating assembly 60. Rotate to to turn the page.

As such, according to the present invention, a single page automatic flipping device having a relatively simple configuration and reducing the occurrence rate of failures, so that each component operates smoothly with each other organically and automatically turns the page P more smoothly (1) ) Is provided.

In the meantime, the description of the above-described embodiment shows a general page turning apparatus 1, such as reading. However, referring to FIG. 6, an example is shown for the case where the above-described page turning device 1 is applied to a piano.

Referring to FIG. 6, the piano includes a piano body 91, a keyboard 92, a lid 93 for rotating and opening the keyboard 92, and a tuning pedal 94 provided at a lower end of the piano body 91. Has

Looking at such a piano, there is provided a music stand (not shown) for placing the music in the cover 93, the book support 10 of the automatic page turning device 1 of the present invention is placed in this area. And, unlike the one shown in Figure 1, the controller 80b is provided in a position adjacent to the lower tuning pedal 94 of the piano to be adjusted to the left foot.

When playing the piano in this state and reaching the time when the score is reached, the controller 80b is operated by using the left foot, which was not used at the time of playing. Then, since the page P is turned through the above-described process, the player can perform the performance while watching the next sheet music. Therefore, as in the related art, it is possible to solve the inconvenience and inconvenience that the separate assistant player must pass the sheet music instead during the piano playing process.

As such, when the automatic page turning device 1 of the present invention is adopted, it can be very useful for those who want to read a book in a comfortable state, including not only physically disabled persons who cannot use both hands but also performers who need to play with both hands. There will be.

In the above embodiment, the type of book is not described separately. However, in a typical book, it can be seen that the size of each page (P) is different. If you want to apply the ideas of the present invention to all of these books as it is, it is necessary to employ a different turning bar 50, or to change the position of the holder 40 coupled to the turning bar 50.

In the above-described embodiment, the pages P are turned one by one by operating the controllers 80a and 80b, but a separate timer is further mounted on the driving motor 30 and the timers can be set by the controllers 80a and 80b. If so, the pages may be turned one by one in a single operation.

7 of the accompanying drawings is a premise application drawing showing another embodiment of the pivot assembly of the present invention when the assembly structure of the drive motor and gears is simplified by the actuator 100. The driving force is superior to the various examples described above, and the structure is simple.

As described above, according to the present invention, it has a relatively simple configuration to reduce the failure rate, and each component operates smoothly with each other organically has the effect of automatically turning the page more smoothly.
