Description

Hand-held electronic device, standard typing keyboard and its multi-function keys

technical field

The invention relates to a hand-held electronic device, in particular to a keyboard structure and multi-function keys applied to the hand-held electronic device.

Background technique

Handheld electronic device (Handheld electronic device) refers to a small, portable electronic device, such as a mobile phone (Mobile phone), a palmtop computer (Pocket PC) or a personal digital assistant (PDA) and so on. Since the handheld electronic device can be used in the fields of wireless communication and Internet, it brings convenience to people's life and more efficient mobile communication processing, and has become the most popular high-tech electronic product nowadays. However, the panel of the handheld electronic device has only the size of a palm, and the area of the screen occupies most of the area of the panel, so the number of keys on the panel is significantly reduced, and the keyboard (QWERTY keyboard) used for general standard typing cannot be used. ) keys are all arranged on the panel, so the portable keyboard (portable keyboard) has gradually become a peripheral input device of a mobile phone.

1 to 3 are schematic diagrams illustrating the assembly of three conventional mobile phones and keyboards respectively. Please firstly refer to FIG. 1, in terms of the design trend of mobile phones, in the past, the area of the screen 12 of the mobile phone 10 only accounted for 1/3 or 1/4 of the total panel area, and most of the remaining areas were arranged in multiple Rows and columns of keys 14 are used, and the keys 14 are generally located on the panel surface below the screen 12 . If the area of the screen 12 of the mobile phone 10 is increased, the distance between the buttons 14 must be relatively reduced and small-sized buttons must be used. However, the buttons 14 are too small to be used, so a large-scale mobile phone that can be connected to an external mobile phone is provided on the market. The keyboard 16 is used to solve the problem of inconvenient input on the mobile phone 10, but the large keyboard 16 occupies too much space and is inconvenient to carry.

In addition, as shown in FIG. 2, more and more mobile phones 20 are designed to be widened horizontally. On the one hand, the total area of the screen 22 can be increased, and on the other hand, the lateral area of the panel can be increased. Build more buttons 24, without a plurality of letter keys or numeral/symbol keys being located on the same button 24. However, this design makes it difficult for the user to hold it with one hand during a call, and the width of the main body casing increases, so the area of the panel must be relatively increased, which cannot meet the design requirements of lightness, thinness, shortness, and smallness.

In addition, please refer to shown in Fig. 3, is to draw another kind of PDA30, the area of its screen 32 even accounts for 3/4 or higher of the total area of the panel, and only some function keys 34 are reserved on the panel, and the remaining number/symbol keys Or letter key then adopts the mode of stylus to click screen 32 to input, but in order to speed up the speed of input, a kind of external miniature keyboard 36 is provided on the market, in order to solve the problem of inconvenient input. However, the keys 38 used in the small keyboard 36 still have disadvantages such as too small spacing and are not easy to carry, so they cannot be used as smoothly and conveniently as the keys used in the large keyboard.

In order to solve the above inconveniences in using the portable keyboard, US Pat. No. 5,861,823 discloses a data input device having multiple rows and columns of multifunction keys. Each function key has an outline such as an egg shape (as shown in Figure 2), a triangle (as shown in Figure 4) or a square (as shown in Figure 5), wherein the central position of the egg shape, triangle or square represents a Numeral symbols, while the two tips of the egg, the triangular area of the triangle or the four corner areas of the square represent a plurality of alphabetic symbols or operational symbols respectively. Although this input device has disclosed a multi-function key that can input at least 3 symbols, when the same multi-function key needs to input different symbols, it is still necessary to use a function key (mode key, such as function key 24 in Figure 1) to switch The symbols to be input are not as easy to use as the keyboard used for standard typing, and the arrangement of the letters and symbols is more unusual than the familiar typing arrangement, which will be more difficult for the user without looking at the keyboard. Alphabetic symbols can be entered.

Then, U.S. Patent Office No. 5,841,374 discloses a small-sized text editing device, which has 12 multi-function keys arranged in standard typing, and each multi-function key has 7 input modes, which can output alphabetic symbols, numerical symbols, and arithmetic symbols in total. And 84 key types such as other function keys. Though the number of keys can be reduced by utilizing multifunctional keys, if viewed from the spacing of the keyboard arrangement, the spacing between adjacent two-letter symbols (such as A, S, D, F) in the middle row is obviously too wide, while the upper row or The distance between two adjacent symbols in the lower row (such as Q, 1, !) is obviously too narrow, so that when the operating flexibility of each finger of the palm and the force and accuracy of the input are deviated, they accidentally touch other buttons on the same button. The possibility of symbols increases, so the user is not easy to enter the input state of normal typing.

Furthermore, US Patent Publication No. 20010006587 discloses a keyboard structure, which has multi-function keys arranged for standard typing, and each multi-function key has three kinds of letters and symbols, which are respectively located on triangular areas of a triangle. Although the number of keys can be reduced by using multi-function keys, if viewed from the spacing of the keyboard arrangement, the letter symbols (such as S) in the middle row are too close to the letter symbols (such as W, E) in the adjacent upper row, causing When the accuracy of finger pressing deviates, the possibility of touching other symbols of different keys increases, so the user is not easy to enter the input state of normal typing.

It can be seen that the above-mentioned existing hand-held electronic devices still have many defects, and further improvement is urgently needed. In order to solve the problems existing in handheld electronic devices, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and general products do not have a suitable structure to solve the above problems.
