Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an input device provided on an input operation surface of a mobile phone, for example, and more particularly, to an input device and an electronic device that detect a rotation operation of the input operation surface in a non-contact manner.
[0002]
[Prior art]
Generally, as an example of an input device provided in an electronic device such as a mobile phone or a personal computer, a display, a dial unit, left and right push buttons, numeric keys, and various input keys are mounted on the upper surface of the mobile phone. The image displayed on the display is scrolled using the dial portion and the left and right push buttons, or the cursor on the screen is moved in an arbitrary direction.
[0003]
In this case, the rotation information on the rotation direction and the rotation amount obtained when the user rotates the cylindrical dial portion on the upper surface of the mobile phone, the part of which freely protrudes a part of the roller surface, is rotated by the fingertip. In order to perform the detection, rotation information of the dial unit is obtained by an encoder provided on the shaft of the dial unit (for example, see Patent Document 1).
[0004]
[Patent Document 1]
JP-A-2001-283885.
[0005]
[Problems to be solved by the invention]
However, in the detection structure using such an encoder, an electrical signal is read by a mechanical contact-compatible structure that detects rotation information by bringing a conductive member into contact with a part of the dial portion, which has an adverse effect on dust and dust contamination. And the wear of the contacts and brushes increases in proportion to the degree of use of the dial portion. As a result, the contact reliability and the service life have to be reduced with long-term use.
[0006]
In particular, in the structure corresponding to the contact of the dial portion, complicated processing is required for processing of a molded product in which the terminal is embedded, bending of the terminal, and the like, which has been difficult to manufacture. Also, when assembling, since the shape of the parts is complicated, it is difficult to assemble the brush because it is mounted while adjusting the positional relationship with the terminals.
[0007]
In view of the above, the present invention includes a detection unit that detects rotation information of a rotating body rotated by a user in a non-contact manner, so that the detection performance is not deteriorated even when used for a long time, and a highly reliable detection signal is obtained. An object is to provide an input device and an electronic device that can be continuously supplied.
[0008]
[Means for Solving the Problems]
The present invention provides a rotating body that is freely rotatable and pressed by touching a user's fingertip, includes a permanent magnet on the rotating body, and detects the polarity of the permanent magnet. The input device includes a non-contact detecting unit that detects a rotation direction and a rotation amount of the input operation.
[0009]
Here, the rotating body can be constituted by, for example, a cylindrical shaft body that supports both ends in the axial direction and freely rotates forward and backward.
[0010]
The permanent magnet can be formed using a magnet having a high degree of manufacturing freedom suitable for incorporation into details, for example, a bonded magnet that can be manufactured into an arbitrary shape by mixing magnetic powder and resin.
[0011]
The detection means may be constituted by, for example, a Hall IC that detects the polarity of the N pole and the S pole of the permanent magnet and converts the polarity into an electric signal.
[0012]
The input device can be applied to an input operation surface such as a mobile phone that is suitable for a user's fingertip input operation.
[0013]
In this case, by detecting a change in polarity, such as a change in magnetic field strength or the number of occurrences, which alternately appears between circumferentially different polarities of the N pole and the S pole during rotation of the permanent magnet rotating integrally with the rotating body. In addition, it is possible to detect the rotation information of the rotation direction of the rotating body in the forward and reverse directions and the rotation amount in a non-contact manner. As a result, there is no part that is physically worn due to rotational contact, and there is no adverse effect such as debris adhering to the rotational contact part, which degrades contact performance. It is completely eliminated, and a highly reliable detection performance and semi-permanent life extension can be achieved.
[0014]
According to another aspect of the present invention, a rotating body held by a user to be freely rotated and pressed by touching a fingertip and left and right operation buttons held by both sides of the rotating body so as to be freely pressed are independently provided as devices. Mounted on the base of the main body, and on the base on the lower surface opposite to the pressing direction of the rotator and the left and right operation buttons, each push detection switch of the rotator, the left operation button and the right operation button is provided. Non-contact detecting means for providing a rotating body with a permanent magnet, and detecting a rotating direction and a rotating amount input to the rotating body based on detecting a polarity of the permanent magnet. It is characterized by having.
[0015]
Here, the operation button is arranged such that a reversing spring is elastically opposed from below so that the operation button can be pressed from above, and when the operation button is pressed against the reversing spring, a switching operation is performed to detect a pressing signal.
[0016]
The base can be composed of a flat board on which each component is mounted.
[0017]
The press detection switch may be configured as a reversing spring switch that opens and closes between the contact portions corresponding to the operation button.
[0018]
In this case, in addition to a non-contact detection function of detecting rotation information of the rotating body in a non-contact manner, a multifunctional input unit combining a pressing detection function of the rotating body itself and a pressing detection function of both operation buttons. Can be established.
[0019]
Therefore, even in the case of using a composite input that can perform various input operations suitable for input types such as confirmation of display items and on / off operations for execution, rotation information can be detected in a non-contact manner. The performance can be improved and the service life can be extended.
[0020]
Further, when the left and right operation buttons are provided, an internal space for obtaining a vertical pressing stroke is required directly below these buttons, but on the small diameter axis at one end of the rotating body corresponding to this internal space. Permanent magnets can be efficiently installed around and incorporated into the vehicle. Therefore, even if the permanent magnet is incorporated, the size of the input device does not increase.
[0021]
Another embodiment of the present invention is characterized in that permanent magnets having different polarities are alternately provided in the circumferential direction of the outer peripheral surface of the rotating body.
[0022]
In this case, the detecting means detects the change in the polarity between the N pole and the S pole of the permanent magnet disposed in the circumferential direction of the outer peripheral surface of the rotating body in a non-contact manner, and converts the change into an electric signal only by converting it into an electric signal. The rotation information of the rotation direction and the rotation amount can be accurately obtained.
[0023]
In addition, by providing the position where the permanent magnet is provided in the circumferential direction of the outer peripheral surface of the rotating body, the magnetic field generation area is widened, and the detecting means can increase the magnetic force generated by the permanent magnet.
[0024]
Another embodiment of the present invention is characterized in that permanent magnets having different polarities are provided alternately in the annular direction of the end face of the rotating body.
[0025]
In this case, since the N pole and the S pole of the permanent magnet can be provided on one end surface of the shaft, the permanent magnet can be efficiently provided compactly in the axial direction of the rotating body. Can be shortened in the axial direction to reduce the size.
[0026]
According to another embodiment of the present invention, a push detection switch that traverses the axial direction of the rotating body in the left-right direction on the upper surface of the apparatus main body and faces the lower surface side of the rotating body on the axial center line of the rotating body is provided. The input device is set and disposed on the front side of the position.
[0027]
In this case, when the user rotates the rotating body with the fingertip, an operating force may be applied from the near side to the front from the position on the axial center line of the rotating body. Even if the pressing force of the diagonally downward direction is mixed and added, and despite the rotation operation, the force is excessively applied and the rotating body is pressed down, even if the rotating body is pressed down, the pressing corresponding to the pressing diagonally downward and forward Since there is no push detection switch, the erroneous operation is eliminated.
[0028]
For example, when the mobile phone is gripped with one hand, when the rotating body is rotated forward with the belly of the gripping thumb, there is no push detection switch diagonally below the front corresponding to the push, but on the axial center line. Since the press detection switch is disposed on the front side of the position, an erroneous press operation is not applied during the rotation operation, and the erroneous press operation is eliminated by detecting only the rotation operation force during the rotation operation.
[0029]
When such an input device is provided in an electronic device such as a mobile phone, for example, it can be efficiently used as a small and highly reliable input device suitable for fine input operation with a fingertip.
[0030]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings.
1 shows an input device provided in a mobile phone. First, FIG. 1 shows a mobile phone 11, which is provided on a top surface of a case body 12, a display 13, an input device 14, an input key 15. Are arranged in order, and an antenna (not shown) is attached to the upper end or the rear side of the case body 12 to be integrally formed.
[0031]
The above-described input device 14 has a switch function for detecting a rotation operation when input from the upper surface of the case body 12, a switch function for detecting a depression operation at the rotation position, and an independent depression operation at the left and right positions. It has a composite input function having a total of four types of switch functions including both switch functions for detection, and is incorporated in the mobile phone 11.
[0032]
As shown in FIGS. 2 and 3, the input device 14 includes a left operation button 16, a right operation button 17, an operation dial unit 18, and a flexible substrate 19, which are stacked in this order on a base 20 from above. It is integrated.
[0033]
The above-mentioned base 20 has a horizontally long rectangular plate shape. As shown in FIG. 4, a first position for rotatably supporting the operation dial unit 18 is provided at opposing positions in the upper surface in the longitudinal direction. A pair of left and right first standing pieces 21 with a shaft support hole 21a opened, and a pair of left and right second standing pieces with a vertically long slot that guides the vertical movement area of the operation dial unit 18 as a second shaft support hole 22a. 22 are provided standing up.
[0034]
Further, a third upright piece 23 having a third shaft support hole 23a for supporting the left operation button 16 is provided at the front-rear facing position on the left side of the upper surface in the transverse direction of the upper surface, Similarly, at the front-rear facing position on the right side of the upper surface in the lateral direction of the upper surface of the base 20, fourth standing pieces 24 each having an opened fourth shaft support hole 24a for supporting the right operation button 17 are provided so as to rise. .
[0035]
These first to fourth upright pieces 21 to 24 have not only the function of supporting the shaft but also the role of positioning and locking the outer surface of the upright piece, which rises at a substantially right angle, around the outer edge provided corresponding to the base shape of the flexible substrate 19. The front, rear, left and right edges of the flexible substrate 19 are positioned on the base 20 surrounded by the standing pieces 21 to 24 and are mounted at fixed positions.
[0036]
The above-mentioned flexible substrate 19 has a first press detection switch SW1 at the center position of the front end corresponding to the base shape, a second press detection switch SW2 on the left side, and a third press detection switch SW3 on the right side. Further, a hall IC 25 for detecting rotation information corresponding to a permanent magnet described later is mounted at the center position on the right side.
[0037]
The above-described first to third press detection switches SW1 to SW3 are integrally formed by superimposing a circular reversing spring 27 on a circular film 26. Usually, the central part of the circular reversing spring 27 is protruded to a middle height. A pusher, which will be described later, is provided opposite to the upper surface of the central portion. When the circular reversing spring 27 receives a pressing operation force, the circular reverse spring 27 reverses downward and turns on a pressing detection switch to output a detection signal.
[0038]
FIG. 5 shows a state in which the operation dial unit 18 is mounted on the base 20 via the flexible substrate 19, and the operation dial unit 18 pivots a horizontally long operation dial 28 on a horizontally long frame 29 so as to be freely rotatable. It is mounted in a state where it is supported. A first support shaft 29a and a second support shaft 29b protrude from both left and right ends of the frame body 29, and the first support shaft 29a and the second support shaft 29b protruding from the left and right sides are connected to the base 20. The center pusher 30 which is rotatably supported by the first shaft support hole 21a and the second shaft support hole 22a of the upright pieces 21 and 22 standing on both sides of the frame 29, and is vertically provided at the center of the lower surface of the frame body 29. Is provided in correspondence with the depression of the first depression detection switch SW1 on the base 20.
[0039]
After the operation dial unit 18 is mounted, the left and right operation buttons 16 and 17 are mounted. The operation buttons 16 and 17 are mounted in a mountain-shaped semicircular shape so as to cover the upper surfaces on both sides of the operation dial 28. You. The left operation button 16 is configured such that a pair of front and rear third support shafts 31 protruding from the front and rear surfaces are rotatably pivoted in third shaft support holes 23 a of a third upright piece 23 that is erected at the left and front facing positions on the base 20. The right operation button 17 is supported, and a pair of front and rear fourth support shafts 32 projecting to the front and rear surfaces are freely rotatable in fourth shaft support holes 24a of the fourth upright pieces 24 that are erected at right and front opposing positions on the base 20. It is supported by.
[0040]
Further, a left pusher 33 vertically provided on the lower left side of the left operation button 16 is provided in correspondence with the second press detection switch SW2 on the flexible substrate 19, and further vertically provided on the lower right side of the lower surface of the right operation button 17. The right pusher 34 is provided to correspond to the third push detection switch SW3 on the flexible substrate 19 (see FIG. 2).
[0041]
Next, the detection configuration of the first to third press detection switches SW1 to SW3 will be described in detail.
[0042]
First, when the operation dial 28 corresponding to the first press detection switch SW1 receives the pressing operation force of the user, the first support shaft 29a is rotated downward together with the frame 29 at the rotation fulcrum to push the center of the lower surface. The child 30 presses down the first press detection switch SW1 thereunder to perform a switching operation.
[0043]
In this case, the arrangement position of the first press detection switch SW1 is set slightly before the position on the axial center line of the operation dial 28, as shown in FIG.
[0044]
As a result, when the user rotates the upper surface of the operation dial 28 with the fingertip F, an operation force is applied in a direction in which the operation dial 28 is pressed obliquely downward and forward from a position on the axial center line of the operation dial 28 toward the front. However, the first push detection switch SW1 is not provided diagonally below and in front of it, and the first push detection switch SW1 is disposed on the near side of the position on the axial center line. Even if a force is applied diagonally downward and forward, the switch SW1 is not applied, and only a rotation operation force is detected during a rotation operation, and a highly reliable detection signal that eliminates an erroneous pressing operation is obtained.
[0045]
The function of avoiding the erroneous pressing operation is particularly vigorous in a direction in which the fingertip of the thumb extends from the bent state when the operation dial 28 is rotated forward with the thumb of the gripped mobile phone 11 with one hand. Since there is a tendency to move and a strong pressing force is likely to be applied, a remarkable effect can be obtained to avoid an erroneous pressing operation via the operation dial 28.
[0046]
Further, when the left operation button 16 corresponding to the second press detection switch SW2 is pressed from the upper side by receiving the pressing operation force of the user, the second support shaft 31 of the button 16 is turned downward about the rotation fulcrum. By moving (rotating left), the left pusher 33 on the lower surface pushes down a second push detection switch SW2 corresponding to a lower portion thereof to perform a switching operation.
[0047]
Similarly, when the right operation button 17 corresponding to the third press detection switch SW3 is pressed from the upper side by receiving the pressing operation force of the user, the third support shaft 32 of the button 17 is turned downward to the rotation fulcrum. By turning (rotating clockwise), the right pusher 34 on the lower surface pushes down a third push detection switch SW3 corresponding to the lower portion to perform a switching operation.
[0048]
At the time of the switching operation on the first to third press detection switches SW1 to SW3, the operation feeling at the time of pressing is obtained by the feeling when the circular reversing spring 27 is inverted downward. After the pressing operation with the fingertip released, the pressing force is released and the pressing switches SW1 to SW3 are pushed up by the reversing action of reversing the circular reversing spring 27 upward, and return to the original upward movement position.
[0049]
Next, a rotation detecting structure of the operation dial 28 will be described.
FIG. 7 is an exploded view of the operation dial unit 18, and the operation dial unit 18 integrates the operation dial 28, the touch spring 35, the permanent magnet 36, and the frame 29.
[0050]
The above-mentioned operation dial 28 has a sufficient contact resistance when a fingertip touches the outer peripheral surface of the central portion of the long axis to apply either forward or reverse rotational operation force, and is suitable for rotational operation to prevent slipping. An operation surface 37 having small unevenness is provided, and a radial groove 38 for operation feeling of relatively large unevenness is formed on the end face of the small-diameter shaft portion on the left side of the operation surface 37 so as to correspond to a touch spring 35 described later. A cylindrical permanent magnet 36 is integrally fitted and fixed to the small-diameter shaft portion on the right side of the operation surface 37 and is coaxially mounted.
[0051]
In this case, as the permanent magnet 36, a bonded magnet or the like suitable for assembling into the details is used, and as shown in FIG. 8A, permanent magnets having different polarities of N pole and S pole in the circumferential direction of the outer peripheral surface of the cylindrical body. Are alternately equally divided (for example, 6 equally, preferably 12 equally). At this time, a magnetic field μ is generated between different polarities in the circumferential direction of the outer peripheral surface of the permanent magnet 36, and a change in the strength and the number of generated magnetic fields μ are detected by the Hall IC 25 located below.
[0052]
The two Hall ICs 25 are mounted on the upper surface of the lower flexible substrate 19 facing substantially directly below the permanent magnets 36 with their positions shifted. Thus, the rotation direction and the amount of rotation of the permanent magnet 36 are detected by detecting a change in the electric signal corresponding to a change in the intensity of the magnetic field μ generated by the permanent magnet 36 and the number of generations.
[0053]
As described above, when the operation dial 28 is rotated, the Hall IC 25 detects the change and the number of generated magnetic fields μ of the permanent magnet 36 rotating integrally with the operation dial 28 in a non-contact manner, and only converts this to an electric signal. Thus, the rotation information of the rotation direction and the rotation amount of the operation dial 28 can be accurately obtained.
[0054]
The arrangement of the polar portion of the permanent magnet 36 can be set to any shape suitable for manufacturing. For example, as shown in FIG. 8 (B), a pair of left and right circular comb teeth 36a and 36b may be abutted with each other and integrally combined.
[0055]
Small-diameter shafts 28a and 28b protrude from both left and right end surfaces of the operation dial 28, and these small-diameter shafts 28a and 28b are supported by a frame 29 described later substantially horizontally.
[0056]
The above-mentioned frame body 29 is provided integrally with a U-shaped left frame body 39 and a right frame body 40 butted from both sides, and a shaft support hole 39a penetrating through the left end of the left frame body 39 is provided with the operation dial 28. The small diameter shaft 28a protruding to the left is inserted and supported. A small-diameter shaft 28b projecting to the right side of the operation dial 28 is inserted into a shaft support hole 40a penetrating through the right end of the right frame 40 to support the shaft.
[0057]
At this time, between the inner surface of the left end portion of the left frame 39 and the axially opposed surface of the radial groove 38 of the operation dial 28, a tactile spring 35 for providing resistance for rotational feeling of the operation dial 28 is interposed. I have.
[0058]
The above-mentioned touch spring 35 is provided with a leaf spring in an inverted V-shape, and is interposed in the axial direction with elasticity provided between the V-shapes. The radial groove 38 of the operation dial 28 comes into contact with and opposes the protruding piece 35a, and when the operation dial 28 rotates in one of the forward and reverse directions, the uneven surface of the radial groove 38 intermittently contacts the touching protruding piece 35a. Thus, an operational feeling in the rotating direction can be obtained. In addition, a center pusher 30 is vertically provided on the lower surface on the center side of the right frame 40.
[0059]
In this way, the operation dial 28 is supported by the frame body 29 and is freely rotatable forward and backward (see FIGS. 3 and 4).
[0060]
By the way, when the left and right operation buttons 16 and 17 are provided, an internal space for obtaining a vertical pressing stroke is required directly below these buttons 16 and 17, and an operation dial corresponding to this internal space is required. Since the permanent magnet 36 can be efficiently installed around the small-diameter shaft at one end and incorporated, the input device 14 does not increase in size even if the permanent magnet 36 is incorporated.
[0061]
When the user operates the input device 14 configured as described above, for example, in a state where the user touches the upper surface of the operation dial 28 lightly with a fingertip in order to scroll the display image on the display 13 in the vertical direction. When rotated, the coaxial permanent magnet 36 rotates in the same direction in conjunction with the rotation, and the intensity change and the number of generated magnetic fields μ alternately appearing between the N and S poles of the permanent magnet 36 having different polarities. Is detected by the Hall IC 25 corresponding to the lower side and converted into an electric signal, thereby transmitting either the forward or reverse rotation direction and the amount of rotation of the rotated operation dial 28 to a central processing unit (not shown) to display the displayed image. Is controlled to scroll upward or downward by the rotation operation.
[0062]
As a result, display items such as a display menu, an outgoing / incoming call history list, a telephone directory list, and a game image are scroll-displayed on the display 13. In addition to the scroll operation, the cursor on the display screen can be moved and displayed.
[0063]
The operation dial 28 is normally in a press-standby state that can be pressed other than the rotation operation. When the operation dial 28 is pressed downward, the operation dial 28 is pushed down and moves downward, and the central pusher is accordingly moved. The switching operation is performed by pressing the first push detection switch SW1 corresponding to the downward push of the first push detection switch SW1. As a result, selection and determination of the display items displayed on the display 13 can be executed.
[0064]
Further, when the left operation button 16 is pressed down, the left operation button 16 moves down to perform switching operation of the second press detection switch SW2, and an input signal on the left side is detected. Similarly, when the right operation button 17 is pressed, the right operation button 17 is moved down to switch the third press detection switch SW3, and the right input signal is detected.
[0065]
As described above, since the rotation information of the operation dial 28 can be detected in a non-contact manner, there is no need for a mechanical contact portion to physically rotate and contact to obtain a detection signal. Service life can be extended. Further, in addition to the non-contact detection function, a multifunction detection input unit can be constructed by combining the press detection function of the operation dial 28 itself and the press detection function of both the operation buttons 16 and 17. .
[0066]
FIGS. 9 and 10 show an operation dial 91 according to another embodiment of the present invention. The operation dial 91 is provided with a permanent magnet 94 of a tubular body 93 that can be fitted to the right side of a shaft portion 92 of the operation dial 91. It is a thing. Since the operation dial 91 is the same as the operation dial 28 except for the permanent magnet 94, the same description will be omitted, and only different points will be described.
[0067]
In the permanent magnet 94, N poles and S poles are alternately and equally distributed in the annular direction of the end face of the cylindrical body, and the strength and the number of generated magnetic fields μ between different polarities on the end face are detected by the Hall IC. Things.
[0068]
In this case, since the N and S poles of the permanent magnet 94 can be provided on the shaft end surface of the operation dial 91, even if the axial length direction of the permanent magnet 94 is short, the detection of the polarity is not hindered. The magnet 94 can be efficiently provided in a compact manner. As a result, the axial direction of the operation dial 91 can be shortened to reduce the size.
[0069]
In the input device 14, the flexible substrate 19 is mounted on the base 20 for wiring connection. However, the present invention is not limited to this. As shown in FIGS. To the third press detection switches SW11 to SW13, and the first to third press detection switches SW11 to SW13 on the lower surface of the base 111 and the respective terminals 112 respectively corresponding to the Hall IC (not shown). A device 113 can be provided.
[0070]
As described above, since the rotation information of the forward and reverse rotation directions and the rotation amount of the operation dial can be detected in a non-contact manner, there is no part that is physically rotated and worn, and the rotation contact part is No adverse effects such as the deterioration of contact performance due to the adhesion of dust or dirt are eliminated, and the deterioration of detection performance due to wear is completely eliminated, so that highly reliable detection performance and semi-permanent extension of life can be achieved.
[0071]
In correspondence between the configuration of the present invention and the configuration of the above embodiment,
The rotating body of the present invention corresponds to the operation dial 28 of the embodiment,
Similarly,
The detecting means corresponds to the Hall IC 25,
The device body corresponds to the case body 12,
Although the electronic device corresponds to the mobile phone 11,
The present invention can be applied based on the technical idea described in the claims, and is not limited to only the configuration of the above embodiment.
[0072]
For example, in the above-described embodiment, a Hall IC is applied to the detecting means. However, the present invention is not limited to this, and may be configured by a combination of a Hall element and an IC.
[0073]
【The invention's effect】
According to the present invention, since the rotation information of the rotation direction and the rotation amount of the rotating body in the normal and reverse directions can be detected in a non-contact manner using the permanent magnet, there is no part that is physically rotated and worn due to contact. In addition, there is no adverse effect such that dust or dirt adheres to the rotating contact portion to deteriorate the contact performance, and deterioration due to wear is eliminated, thereby improving reliability and extending the life.
