Although the example - Ming ": The new technology is a reference to the specific ... but it should be understood that the examples described in this article only provide some examples of the beneficial use of this innovative technology. Now refer to Figures 1, 2 and 3, each: ^ Do not follow this A typical example of the invention is the top, side and/or the input device 5. The input device 5 can be used for a mobile phone or for navigation or control of a household: Ϊ Ϊ: in other electronic devices. The input device 5 comprises a non-ferromagnetic material ^ The circular disc 10 is included. The circular disc 10 includes a plurality of ferromagnetic plates 12 attached or inserted into the periphery thereof. The ferromagnetic plate 12 can be placed on one side of the disc 1 , in a circle The disc 1 is either protruded out of the disc. The ferromagnetic plate 12 can be made of any ferromagnetic material such as steel. The disc 10 is mounted on the support member 22 in such a manner as to rotate the bowl. A printed circuit board 18 is attached to or fixed to any of the electronic devices. In general, the support member 22 is rotatably coupled to the axis of the disk, that is, the center of gravity of the disk. Balancing the rotation of the disc 10. The input device 5 is placed on the printed circuit board 18 and located A magnet 14 near the periphery of the disc 10 and a magnetic sensor 16 (e.g., a 'hall, sensor). The magnetic sensor 16 has a specific sensitivity axis. The magnetic sensor 16 outputs when it reaches its hysteresis level. - Signal. This point means that the magnetic sensor 16 outputs the signal when the magnetic field described below exceeds a minimum level. The position of the magnet 14 is to attract each ferromagnetic when the plate 12 is within a predetermined distance from the magnet 14. The board 12 is magnetically sensed 16 on the printed circuit board 18 near the magnet 14 and its sensitivity axis is oriented parallel to the north to south pole of the magnet 14 such that when the board 12 passes the distance from the magnetic sensing 16 - pre-foot distance The time sensor 16 generates a signal that is supplied to a microcontroller (not shown) of the electronic device. The microcontroller responds to the signal, that is, 1267885 (4) ----^ The electronic device displays on-screen, s, and ra reel scrolls. Especially the plywood]?, the magnet 14/magnetic sensor 16 is combined with Ueda, and the eyes, 1 crying in the plate and the magnet 14/magnetic sense. The magnetic field between the 16 combinations becomes a concentration ^ h is concentrated and increased. The magnet Μ and the plate 12 are phased together; the magnetic resistance gap is reduced. -, state 16 responds to the concentration of the magnetic field to produce a detectable signal. The position of the disc 10 is such that the disc 10 and the associated ferromagnetic plate 12 are separated from the magnet 14 and the magnetic sensor 16 so that the 0 disc 1 can be rotated without contacting the magnet 14 and the magnet. Sensor 16. In addition, when the ferromagnetic plate 12 passes over the magnet 14 and the magnetic sensor 16, the magnetic field is concentrated across the gap and is in any contact between the plate 12 and the magnet 14 or the magnetic sensor 16. It should be understood that the gap can be such that there is a suction between the magnet 14 and the plate 12 at any distance to provide sufficient magnetic field concentration to activate the magnetic sensor 丨6. When the ferromagnetic plate 12, the magnet 14 and the magnetic sensor 16 form a concentrated magnetic field, the magnetic sensor 16 outputs a signal through the printed circuit board 18 to connect to the printed circuit board 18 for another component, such as a micro process. (not shown). The microcontroller controls the function viewer to view and display the results on a screen (i.e., an LCD screen (not shown)). However, it should be understood that the signals produced by magnetic sensor 16 can be used in any desired control application. When the disk 10 is rotated and a ferromagnetic plate 12 in the disk 1 is passed over the magnet and the magnetic sensor 16, a gravitational force between the magnet 14 and the plate 12 is applied to the disk 1 One of the rotational resistances of the disc 10, that is, a slight pause. This rotational resistance provides the input device user with a sensible feedback equivalent to some of the operations/functions performed by the signals generated by the magnetic sensor 16. Therefore, the sensible feedback of the attraction between the magnet 14 and the ferromagnetic plate 12 can cause the user to operate the input device 5 by the resistance of the user who feels the rotation of the input device 5 (1) 1268885. feel,. For example, this operation may be a full scrolling menu and in each step of scrolling the user feels a resistance to one of the scrolling steps (i.e., pause). If the user quickly scrolls through multiple entries of the menu, he or she will feel multiple rotational resistance feedbacks, and each feedback is equivalent to one step. Referring now to Figures 4A and 4B, the input device 5 of the present invention is shown in the figure. Another example and a timing diagram of the signals generated by input device 5 in this example. The input device 5 of this example is substantially identical to that described in Figures 1-3. In the present example, however, the input device 5 has at least two magnets 14a and 14b and at least two magnetic sensors 1 and 16b. The magnetic sensor 16a or 16b is located adjacent to the magnet 14a or 14b associated therewith and its sensitivity axis is also parallel to the associated magnet 1 or 14b. The magnets 14a and i4b can be placed symmetrically near the periphery of the disc 10 (i.e., at the opposite ends of the disc) so that the attractive force from the magnet 14 on the ferromagnetic plate 12 does not cause on the disc 1 or the rotation of the disc 1 Balance your strength. The magnetic sensors 16a and 16b are respectively located near the magnets 14& and Hb and are placed symmetrically with each other. In other words, the magnetic sensor... is on the side of the 10 axis of the disc. The positions of the magnetic sensors 16a and I6b are such that when the disk 10 is rotated, the first plate 12a is before the second plate (10) on the opposite end of the disk 10 enters a predetermined distance from the second magnetic sensor 16b. Entering a predetermined distance from one of the first magnetic sensors 16a.

A ferromagnetic plate 12a generates a first signal (S1) by a first magnetic sensor 16a from the first magnet 1 (i.e., due to a high logic value appearing on the output of a concentrator 16a as described above) ). in

However, since the position of the second magnetic sensor 16b is symmetrical with the first magnetic sensor 16a, a concentrated magnetic field is not formed (i.e., the magnetic field does not exceed the minimum level required to generate a signal). When the disc 12 is further rotated, the second ferromagnetic plate i2b causes a concentrated magnetic field between the first magnet 14b and the second ferromagnetic plate through the second magnet ub to cause the second magnetic sensor 16b to generate the second signal (S2). ) (ie, a high logic value appears on the output of the second magnetic sensor 16b). This configuration enables the second magnetic sensor 1 to generate the second signal (S2) faster after the first magnetic sensor 16a generates the first signal (S1). Thus, the direction of rotation of the disc 10 can be varied in accordance with the order in which the first (S1) and second (S2) signals are generated by the first and first magnetic sensors 16a and 16b. For example, if the second signal (S2) is generated by the second magnetic sensor 16b after the first signal (si) is generated by the first magnetic sensor 16a, the rotation of the dove wheel 1 is toward the first direction ( For example, clockwise). In addition, if the face number "S2" is generated before the first signal (S1), it can be confirmed that the rotation of the disk 10 is in the second direction (for example, counterclockwise direction), and the input device should be known. 5 The sensible feedback provided by the user, the operation mode of which is the same as the above-mentioned one is also to provide the rotation resistance when the ferromagnetic plate is near the magnet 14. In a preferred example, the first magnetic sensor 16a is generated. The first signal (S1) disc basket - dj /, - the time difference between the second signal (S2) generated by the sensor 16b (S), η, 会, will make the user feel the two magnets 14a and 14b and The two suctions of the two panels 12a are only a single attraction. This results in an early feedback to the user and shows the signal generated by the desired function and still enables the input device to determine the rotation of the disc 10. Directions. The direction of rotation of the disc 10 can be determined by other methods. For example, -11 - 1267885 Description of the invention (7) Position of at least two magnets 14a and 14b and at least two magnetic sensors 16a and 16b can be placed When the circular disk 10 rotates, the second magnetic sensor 16b is cancelled in the first magnetic sense, and the j device 16a The signal is generated before the signal is generated (that is, the concentrated magnetic field involving the magnetic sensors 16a and 16b can be generated because the iron plate is wide enough). Which one of the stones sensor 16a or 16b starts to generate the signal first. The direction of rotation can be determined. In addition, this configuration helps to avoid the possibility that the direction of rotation may occur when only one of the magnetic senses 16a or 16b detects a concentrated magnetic field. In another option, a single or multiple pairs of magnets/magnetic sensors can be used for ferromagnetic plates 12 of different thicknesses and when one of the plates is formed with magnets 14 or magnetic sensors 16 When a concentrated magnetic field is concentrated, different magnetic field strengths may be generated. Depending on the field strength, the intensity of the signal generated by the magnetic sensor 16 may be different. In this case, the direction of rotation of the disc 10 may be based on the previous signal strength and the current signal. ^ Degrees are compared to determine. It should be understood that placing a number of ferromagnetic plates 12 on the periphery of the disc 1 can increase the discriminating degree of the scrolling operation. Therefore, when there are more plates 12 on the disc 10, one of the discs 10 The step of complete copper rotation The number may increase. For example, if the disc (7) has four ferromagnetic plates 12, in a | | 八, in the turn of the mother four points < one can produce a signal.

When the right disc 10 turns the gravity scent, iEg ^, so that the ferromagnetic plate 12 is within the predetermined distance from the magnet 14, it will not detect the step 八, and if so, the process returns to the waiting dish 1 The extra rotation of the cymbal. ^ When the plate 12 is formed by the magnet si + k ^ , the force is indeed with the magnet Η and a magnetic sensor Η concentrating the magnetic field, the concentrated magnetic field at step 36 enables the magnetic sensor to generate the mud/signal . This current/signal can be used to perform a control job, i.e., scroll up/down volume a menu. As long as the ferromagnetic plate 12 is held within a predetermined distance from the magnet 14, the current/signal continues to be generated. Thus, at step 38, it is determined whether the child's ferromagnetic plate 12 has been removed from the magnet 14 by a predetermined distance. If not removed, the magnetic sensor 16 continues to generate the current/signal. However, in the step * 3 8 - if the ferromagnetic plate 丨 2 has been removed from the predetermined distance (that is, after the disk j 〇 has an additional rotation), the current/signal is stopped at the step and the process returns. Step 30. The process can be repeated any number of times with one or more magnets and/or one or more ferromagnetic plates to navigate through a menu, so that each nickname can initiate a scrolling menu step.
