Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention is a kind of foldable input device, especially for a personal digital assistant, and refers to a connection type input device having an input operation function and portable convenience.

[0002]

[Prior art]

 Personal digital assistants are not only light in volume and convenient to carry, but also have outstanding advantages such as pen input and data communication functions. It is an indispensable item for personal daily life. However, since the personal digital assistant is compact in volume, you must sacrifice personal habits and learn a new way to operate it. The most influential among them is the input method. Due to space limitations, personal digital assistants have to use the pen input function instead of typing on a standard keyboard, which not only slows down input, but is especially severe when inputting large amounts of data. Inconvenient. Therefore, it is necessary to find a way to solve this inconvenience. At present, keyboards compatible with personal digital assistants are commercially available. It mainly emphasizes the convenience of carrying and using. One of the most noticeable is the four-fold keyboard. The only selling point is that it folds almost as large as a personal digital assistant, giving the image of a high-quality user, but these products look good, but often look good There are many items that are useless when knocked down. The cause is that the volume of the personal digital assistant was forcibly reduced and reduced, and the traditional size and tactile feel of the keyboard were lost, which made it unsuitable for ergonomics. Cause injury. Because the position where the personal digital assistant fits in is offset to one side of the keyboard, the user must always look at the eyes diagonally. It is imperative that eye health is impaired over time. In addition, the lack of stability when wearing a personal digital assistant means that it may not fall down and be damaged a little. In addition, the price is high, the failure rate is high, and the expansion capacity is poor. Therefore, the conventional mold is not yet a good design. There are several other foldable keyboard products, for example, U.S. Patent Nos. 5,457,453 and 5,653,543. Although the folding structure is used to compete for ideas and fold the keyboard to make it more convenient to carry, however, the user has not been able to adjust the position of the keyboard regardless of the type, so the user's habits will be reduced. The requirements for the combined operation have not yet been met. And since these keyboards and the personal digital assistant are provided separately, the user often forgets to place one of them, resulting in the sudden death of the characteristics of the portable keyboard. As is clear from the above description, the conventional personal digital assistant still has many disadvantages to be improved.

[0003]

[Problem to be solved]

 One of the aims of the present invention is to provide a foldable input device that matches ergonomics, which is not only convenient to fold and carry, but also has a standard keyboard size when opened for use. There is no change, the operation is convenient, and the keyboard can be adjusted to an appropriate position and angle according to the user. The second aspect of the present invention is to provide a foldable input device that is beneficial to eye health, and to attach the personal digital assistant to the center so that the user can look straight at the screen. To prevent eye fatigue. Third, the purpose of the present invention is to provide a foldable input device so that a personal digital assistant and a keyboard are stored together when carrying the device, so that one of them is not misplaced. Fourth, the purpose of the present invention is to provide a foldable input device with an extended function so that necessary software can be easily and easily inserted, thereby expanding the area of use of the personal digital assistant. .

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings to clarify the technical contents of the present invention and the purpose and effect thereof. 1 to 3 show details of the foldable input device of the present invention. As shown in the figure, the main configuration of the present invention is as follows. It is mainly composed of symmetrical cases 11 and 12, and a joint 2 is provided between the pair of cases 11 and 12. Two fan-shaped plates 31 and 32 are connected to the right and left sides of the joint 2 by rotating shafts 21 and 22, respectively. The right and left ends of the fan-shaped plates 31 and 32 are inserted into the respective cases 11 and 12 opposed thereto, whereby the cases 11 and 12 are relatively folded around the joint 2 and closed. Or open left and right. Keyboard portions 41 and 42 are fitted on the surfaces of the cases 11 and 12, respectively. Also, slides 13 and 14 corresponding to the keyboards 41 and 42 are provided at the upper and lower ends of each of the cases 11 and 12, whereby the keyboards 41 and 42 relatively move left and right within the cases 11 and 12. You can do it. A personal digital assistant (PDA) supporter 23 is provided at the upper end of the joint 2 to insert and mount a personal digital assistant (not shown). A connection port 24 is provided in the personal digital assistant (PDA) supporter 23 so as to be connected to a terminal of the personal digital assistant. In addition, the personal digital assistant (PDA) supporter 23 and the joint 2 are connected to a rotating shaft 25, whereby the personal digital assistant (PDA) supporter 23 is folded flat using the rotating shaft 25. It can be put on the joint 2. An extension rack 231 is provided on the surface of the personal digital assistant (PDA) supporter 23, and when the extension rack 231 is opened and extended at the time of use, the stability is further enhanced when the personal digital assistant is mounted. Be strengthened. The cases 11 and 12 are provided with a separate storage space 5 for storing a personal digital assistant or a spare battery. In addition, a connection port 51 is provided in the storage space 5 and is provided for connection to a terminal of the personal digital assistant or a spare battery. In addition, the storage space 5 can be covered with the cover 52. The cases 11 and 12 are further provided with an expansion slot 6, and the expansion slot 6 is used to insert software such as a memory card, a network card, a digital card, or another PC card. Increase the capabilities of assistants.

FIGS. 4 and 5 are views of the folding input device of the present invention when folded and closed. If the cases 11 and 12 are opened on both the left and right sides with the joint 2 as an axis, then folded back and closed, the length becomes only a half length, which is convenient for the user to carry. In addition, the personal digital assistant can be stored in the storage space, saving space and not having to forget the personal digital assistant. It is also possible to charge the personal digital assistant through the connection port 51 using an external power supply. After the cases 11 and 12 are opened, the user adjusts the distance or angle between the keyboards 41 and 42 as needed to make operation easier. The user can also use the expansion slot 6 to increase the functions of the personal digital assistant. For example, the user can increase the memory capacity or extend the area of use infinitely by directly connecting to the Internet. It is possible. It is a well-known technique to incorporate the circuits of the respective devices in the cases 11 and 12, and the description thereof is omitted here.

The present invention can use a built-in battery or a power source of a personal digital assistant. It goes without saying that an externally connected power supply such as a battery box or an AC power supply can be used. This reduces the power consumption of the personal digital assistant. As mentioned above, charging can be performed at the same time.
