Description

writing board

The present invention relates to an input device, and more particularly to a tablet for use in an electronic device.

Today, electronic devices are extremely flooded with everyday life. People often use electronic devices to record a variety of information, making the keyboard the most convenient way for people to input information. However, familiar with the operation of the keyboard, fast input of text is not any Everyone can adapt, such as children who have just learned to write, or the elderly are not suitable for keyboard operation. Therefore, there is a tablet that uses optical touch to implement handwriting input information. Generally, the touch panel using the optical touch method is equipped with a sensing device such as a camera, a sensor, etc. to detect the movement track of the input device to generate corresponding input information. The sensing device of the above-mentioned tablet generally needs to be supported above the tablet through a support bar to sense the movement trajectory of the input device above the tablet, however, the sensing device disposed above the tablet protrudes from the handwriting The upper part of the board is not only inconvenient for the storage of the tablet, and there is a certain safety hazard, and the support rod supporting the sensing device may injure the user.

In view of this, it is necessary to provide a tablet that is convenient to store and safe to use.

A tablet includes a substrate, a lifting plate and a sensing device. The substrate includes an upper surface, and a groove is formed on the upper surface. The lifting plate can be raised The ground is housed in the slot of the substrate. The sensing device is disposed on the lifting plate and can adjust a position of the sensing device relative to the substrate through the lifting plate.

Compared with the prior art, the tablet of the present invention can provide the sensing device by providing a slot on the substrate and carrying the sensing device through a liftable lifting plate housed in the slot. The lifting plate is housed together in the slot of the substrate, and can also be supported by the supporting plate at a position higher than the upper surface of the substrate to implement a handwriting input function. Thereby the tablet has high security of use.

Referring to FIG. 1, a tablet 100 is provided in a first preferred embodiment of the present invention. The tablet 100 includes a substrate 110, a lifting plate 120, and a sensing device 130. The lifting plate 120 is vertically housed in the substrate 110, and the sensing device 130 is disposed on the lifting plate 120.

The substrate 110 includes an upper surface 112 on which a slot 114 is formed. The slot 114 includes a bottom surface 114a and two side walls 114b that are perpendicular to the bottom surface 114a and are parallel to each other. A sliding groove 114c is respectively disposed on the two side walls 114b along the extending direction of the side wall 114b. The sliding groove 114c extends from one end of the side wall 114b to a middle portion of the side wall 114b, and is disposed in the middle of the side wall 114b. There is a card slot 114d perpendicularly intersecting the chute 114c and penetrating the upper surface 112 of the substrate 110.

The lifting plate 120 is housed in the slot 114 of the substrate 110 in a liftable manner. The lifting plate 120 includes a carrier plate 122 and a support plate 124. One end of the carrier plate 122 opposite to the support plate 124 is hinged to each other. Two sliders 122a are respectively disposed on two sides of the other end of the supporting plate 122 away from the supporting plate 124. The two sliders 122a are slidably engaged in the sliding grooves 114c of the substrate 110 through the card slots 114d on the substrate 110. An end of the support plate 124 away from the carrier plate 122 is hinged on an end of the sidewall 114b of the slot 114 away from the slot 114c.

The sensing device 130 is disposed on one end of the carrier plate 122 adjacent to the support plate 124. The sensing device 130 is configured to sense a position change of an input device such as a stylus, and transmit the sensed result to Handwriting input is implemented in an electronic device (not shown) electrically connected to the tablet 100.

In use, the carrier plate 122 is pushed to slide along the sliding slot 114c of the substrate 110. With the sliding of the carrier plate 122, one end of the supporting plate 124 and the carrier plate 122 are hinged The hinge of the support plate 122 rises toward the upper surface 112 of the substrate 110, and the other end of the support plate 124 rotates along the hinge thereof with the substrate 110. When the slider 122a slides to the position where the card slot 114d communicating with the chute 114c is at the position, the sliding stops, and at this time, the sensing device 130 is supported by the support plate 122 at a higher level than the handwriting. At the location of the upper surface 112 of the board 110, the trajectory of the input device moving on the substrate 110 can be sensed to enable handwriting input. When the tablet 100 is not used, the lifting plate 120 and the sensing device 130 can be received in the slot 114 of the substrate 110, thereby facilitating storage, saving space, and flattening the surface of the tablet 100. Will not stab the user.

Referring to FIG. 2, a second embodiment of the present invention provides a tablet 200. The tablet 200 includes a substrate 210, a lifting plate 220, and a sensing device 230. The lifting plate 220 is vertically movably received in the substrate 210, and the sensing device 230 is disposed on the lifting plate 220.

The substrate 210 includes an upper surface 212. The upper surface 212 includes a handwriting area 212a and a receiving area 212b. A receiving groove 212 is formed in the receiving area 212b of the upper surface 212. The slot 214 includes two mutually parallel side walls 214a.

The lifting plate 220 is housed in the slot 214 of the substrate 210 in a liftable manner. The lifting plate 220 includes a carrier plate 222 and a support rod 224. One end of the carrier plate 222 is hinged on the side wall 214a of the slot 214 and adjacent to the handwriting area 212a of the upper surface 212. A groove 222a is formed on a side surface of the carrier plate 222 facing the slot 214. The support rod 224 is hinged to the bottom of the slot 214 of the substrate 210 corresponding to the recess 222a of the support plate 222, and is received in the recess 222a. It can be understood that the support rod 224 can also be directly hinged in the recess 222a of the carrying plate 222, and when the carrying plate 222 is received in the slot 214, the support rod 224 can be received in the The groove 222a of the carrier plate 222 is described.

The sensing device 230 is disposed on a side of the carrier plate 222 that is away from its hinged end.

In use, the carrier plate 222 is flipped to rotate along its hinge with the substrate 210 while lifting the support bar 224 and supporting the support bar 224 on the side of the carrier plate 222 on which the recess 222a is formed. Thereby, the sensing device 230 is supported above the substrate 210. When the tablet 200 is not used, the support bar 224 is lowered and the carrier plate 222 is received in the slot 214 of the substrate 210 while the support bar 224 is received in the carrier plate 222. The inside of the recess 222a is convenient for storage, saves space, and at the same time flattens the surface of the tablet 100 without scratching the user.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. but The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or changes made by those skilled in the art to the spirit of the present invention should be It is covered by the following patent application.
