Description of the invention () Detailed description [Background of the invention] The present invention relates to a multifunctional key for the main item of the scope of patent application. The Blue Dot catalog "Sound und Fahrvergnuegen pur. Mobile Kommunikation von Blaupunkt. Programm, 97" has mentioned the car radio Autoradio Berlin RCM303-A, which has a multi-function key, which has four multi-function keys on the key surface On the action surface, they are each marked with an arrow symbol. This multi-function key can be brought into four different positions with this action surface. [Advantages of the invention] Compared with this, the function key with the main item of the patent application scope has the advantage that: a bulge is provided between the contacts, which should be hemispherical, which is better than the contact by the opposite of the key surface The side protrudes more. In this way, when one contact moves, it can prevent adjacent contacts from having unwanted closed circuit at the same time. Another advantage is that the multi-function key is integrated into a switch pad in a flexible manner through a diaphragm, so the multi-function key springs back to its starting position after the action. In this way, the manufacture of this multi-function key is simpler because it can be integrated with the entire keyboard into the form of a single switch pad, so an additional key for the multi-function key can be omitted. [Explanation of the drawings] Embodiments of the present invention are shown in the drawings and described in detail in the following description. In the drawing: The first picture is a front view of a switch pad (2) with integrated multi-function keys. ____3____ This paper size is applicable to the Chinese National Standard (CNS) Λ4 specification (210X 297 KRW) ~ "; ( Please read the precautions before filling this page], -0- Λ7 Η 7 V. Description of the invention () The second picture is the rear view of the switch pad with the integrated multi-function key, and the second picture is after the invention A cross-sectional view of one embodiment of the multi-function key, and the fourth diagram is a perspective view of the second embodiment of the multi-function key of the present invention. [Explanation of the embodiment] Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (Please read the precautions before filling this page) The first picture shows the front of a switch pad (2) of a radiotelephone. Here, the switch pad (2) contains an alphanumeric keypad. Telephone keypad. The keyboard keys of the telephone keypad are connected to the switch pad (2) through a surrounding diaphragm, so there is no need for additional key buttons. In addition, a multi-function key (1) is integrated into the switch pad (2). The multifunctional is connected to the switch pad ⑵ via a surrounding diaphragm ⑻. The function key (1) is elastically integrated into the switch pad 经 via the diaphragm ⑻. Here, the multi-function key (1) and the diaphragm (8) are also composed of silicone rubber. Therefore, the switch pad (2) and the telephone The key and the multi-function key (1) are connected into a whole. The multi-function key (1) has a round bottom surface, and the bottom surface is divided into four symmetrical action surfaces (9) on a key surface (3), of which each action surface (9 ) Is provided with an arrow-shaped symbol (5) to indicate the direction of motion. For example, using this multi-function key (1) can comfortably select an operation on an operation surface of an item (which is displayed on a display of this radiotelephone). Function, where the use of the multi-function key (1) can save four individual keys for the corresponding selection direction or action direction, and saves the need for a lot of space on the keyboard. The second figure shows the rear of the switch pad (2) View, in which the same drawing number represents the same element. It can be clearly seen here that the starting operation surface is indicated by a dashed line in the second figure (on the side (1)) opposite to the key surface ⑶ of the multifunctional key. Each is matched with a point (6), and the contact can be used with a _ when the related action surface (9) is depressed. 4____ The scale of this paper is applicable to the Chinese storehouse standard (CNS) Λ4 specification (21〇X2y7). The middle of the Ministry of Goods " ^ / Jy η Xiaoxianhe M ^ 1 卬? Water A7 B7____ 5. Description of the invention () The pair of standing contacts (11) of the plate (12) are connected as shown in the third figure. To this end, the contacts (6) are shown in the third figure, from the multi-function key (1) to the key surface ( 3) The opposite side (10) protrudes. According to the second and third figures, a half circle is provided between the contacts (6) at the center of the side (10) opposite to the key surface (3). Shaped bulge (7) The semi-circular bulge (7) protrudes more from the side (10) opposite the key surface (3) than the contact (6), so the bulge When the action surface (9) is pressed down and a contact (6) comes into contact with the opposite contact (11), it rests on the plate (12). This creates a tilting effect that prevents adjacent contacts from improperly contacting the opposite contact at the same time. In the third figure, the same elements are indicated by the same drawing numbers. As can be seen from the third figure, the multi-function key (1) is approximately designed as a truncated conical key shaft (4), and the outer edge of the side (10) opposite to the key surface (3) passes through the surrounding diaphragm (8) Connect with switch pad (2). Here, the diaphragm (8) can make the multi-function key (10 after the action [that is, after an action surface (9) of the key surface (3) is depressed]] spring back to its starting position, which is characterized by: A contact (6) is provided to connect with the opposite contact (11) of the related plate (12). The fourth figure shows another embodiment of the multi-function key (1), wherein four of the key surface (3) The two action surfaces (9) bulge at least partially. Here, the action surface ⑼ should bulge at the outer edge of the key surface (3), and decrease in degree of program at the boundary (14) of the two action surfaces (9). It is smaller than when the maximum distance between the two action surfaces (14) is reached. This shape allows the user to make a neat connection. When the multi-function key (1) is depressed, the action direction is determined by the raised portion If you do not use the raised action surface (9) of the multi-function key (1) in the fourth figure, [or in addition to this raised surface, you can also make an arrow shape _________5___ / 丨】 Middle-Lanner (CN'S) A4 Specification (2 丨 0X297mm) '^ Read the precautions on the back before filling this page) Order.

Explanation of the invention () ^ The symbol (5) bulges on the key surface (3), which makes it easier for the user to operate and makes the action mode more clearly visible. Because the arrow-shaped symbols (5) point in various directions. The raised portion of the arrow-shaped symbol (5) is shown in the third figure, and is represented by the figure number (13). The design of this multi-function key (1) is also particularly beneficial for the visually impaired or blind, who can only discern the direction of the action in this way. The application of the multi-function key (1) of the present invention is not limited to wireless telephones, but can be used for all electrical appliances to save the space occupied by the individual keys originally required. It can also be used in car radios, mobile phones, radios, computers, personal computers, laptop (Laptop) or the like. In the above embodiment, 'this multi-function key (1) can be brought to four different positions using the action surface (9) to contact the contact (6) with the relevant opposite contact (11), but it can also be based on demand, Use the multi-function key 本 of the present invention to make more or fewer positions, where 'if necessary, when making more than four different positions, the geometry of the multi-function key (1) can be correspondingly matched, To prevent multiple contacts at the same time. If hemispherical bulges (9) are not used, bulges of other shapes can also be used, which similarly protrude more from the side opposite to the key surface (3) than the contact (6) 'and therefore can be the same The method makes the multi-function key (1) tilt between different positions, so that a contact (6) contacts a pair of standing contacts (11), without simultaneously improperly making an adjacent contact (6) opposite to it. Contact (11) contacts. ____6 This paper is in Shizhou 屮 Hardware House 桴 ϋ CNS) 8 4 Specifications (2〗 〇ί 297 公 牦) 4 Read the precautions before filling out this page) Ding ··
