Description

AREA OF INVENTION

[0001] The present invention relates to an input device comprising a process input part for receiving an input process, which is held vertically movable above a base plate, and an electronic device comprising such an input device. BACKGROUND OF THE INVENTION

[0002] A personal laptop computer (laptop PC) is equipped with various input devices in addition to a keyboard, such as a touchpad and a pointing device, as alternatives to a mouse. A touchpad allows the user to manipulate a cursor displayed on a screen by touching it with a fingertip or stylus.

[0003] For such an input device comprising a touch field, the present applicant proposes in patent specification 1 a configuration that enables a touch operation and an actuation operation (input operation) of the touch field. In this configuration, an operation input element is held vertically movable above a base plate for receiving an input operation. For example, a plurality of pseudo-key areas are configured on a touch surface of the touch field (operation input element), which enables an operator to perform an input operation corresponding to each pseudo-key area by actuating (clicking) the touch field while touching the corresponding pseudo-key area.

[0004] Patent specification 1: JP 2013-025422 A

[0005] In contrast, the previously mentioned input device is equipped with an element to define the rise limit (position) of the touch field. When the activated touch field returns to its original position, it comes into contact with this element that defines the rise limit, resulting in a noise (rebound noise). There is a need to reduce this noise, which occurs when a touch field comes into contact with the element that defines the rise limit.

[0006] From publication US 2015 / 0084898A1, an input device is known which comprises: an actuation area that allows the execution of an input operation by an actuating element coming into contact with or near an upper surface thereof; an input detection area that detects an input operation with respect to the actuation area; a drive element provided below the actuation area that drives the actuation area in a vertical direction; an elastic element provided below the actuation area; a housing element that holds the drive element; a coupling element provided below the actuation area that is connected to the actuation area and is driven together with the actuation area;a limiting element provided between the actuation area and the coupling element, limiting upward movement of the coupling element; and an elastic first damping element provided below the coupling element, which can be brought into contact with the coupling element.

[0007] Publication US 2010 / 0139990A1 discloses user input devices that accept complex user inputs, including a combination of touch and print inputs, and that inputs received by such devices can be selectively ignored or rejected by those devices. BRIEF SUMMARY OF THE INVENTION

[0008] In view of the problem of conventional techniques, the object of the present invention is to provide an input device capable of reducing the noise generated when the actuated input part returns to its original position, and an electronic device comprising such an input device.

[0009] This problem is solved by the subject matter of main claim 1 and dependent claim 7, which define the present invention.

[0010] Preferred embodiments of the present invention are the subject of the dependent claims.

[0011] An input device according to the present invention comprises a process input part for receiving an input process, which is held vertically movable above a base plate, wherein the base plate has a hook that projects towards the process input part, the process input part has an arm element that can come into contact with the hook, wherein contact of the arm element with the hook defines a rise limit of the process input part, and wherein at least one of the arm element and the hook is elastic in the contact direction of the same.

[0012] With this configuration, the arm element of the operation input part comes into contact with the hook of the base plate, thus defining the rise limit of the operation input part. Since at least one of the arm element and the hook is elastic in the direction of contact, the noise (rebound noise) generated by contact between the arm element and the hook when the actuated operation input part returns to its original position can be reduced.

[0013] In the input device according to the present invention, the base plate has a different hook compared to the hook, the process input part has a different arm element compared to the arm element, and the other arm element and the other hook come into contact in a position above the rise limit of the process input part, which is determined by contact with the arm element and the hook.

[0014] In this case, the other arm element is configured to make contact with the other hook in a position above the rise limit of the operation input part. Therefore, contact between the other arm element and the other hook prevents the operation input part from detaching from the base plate, even under high force. This means that this other arm element and hook act as a retainer. For example, if a large force is applied that causes the rise limit to be exceeded by the arm element and hook, the retainer prevents the operation input part from falling off the base plate. The other arm element is configured to make contact with the other hook in a position above the rise limit of the operation input part.When the actuated process input part returns to its original position, the arm element and the hook come into contact first to reduce the rebound noise, and the other arm element and the other hook can then serve as holders.

[0015] In the input device according to the present invention, the other arm element, if the arm element is elastic, preferably has a higher stiffness than the first arm element. Since the other arm element has a higher stiffness than the first arm element, in this case, if a large force is exerted on the touch field and the base plate, contact between the other hook and the other arm element can prevent the touch field from detaching from the base plate.

[0016] In the input device according to the present invention, the other hook, if the hook is elastic, preferably has a higher stiffness than the first hook. Since the other hook has a higher stiffness than the first hook, in this case, if a large force is exerted on the touch field and the base plate, contact between the other hook and the other arm element can prevent the touch field from detaching from the base plate.

[0017] In the input device according to the present invention, the arm element and the other arm element can have protruding pieces at their forward-facing ends that project in their opposite direction, and the hook and the other hook can come into contact with their corresponding protruding pieces.

[0018] Preferably, in the input device according to the present invention, the arm element projects in a direction that intersects with the functional direction of an actuation process on the input part, and a portion at the forward-facing end of the arm element comes into contact with the hook. Since the arm element projects in the direction that intersects with the direction of the actuation process on the input part, an increase in the dimensions of the input device in the thickness direction can be avoided in this case, which means that the input device can be thinner.

[0019] In the input device according to the present invention, the process input part can comprise a touch field that can receive a touch process and an actuation process.

[0020] An electronic device according to the present invention comprises: the input device, a keyboard device and a display device for displaying a result of an input process by the input device and the keyboard device.

[0021] Since, according to the present invention, at least one of the arm element and the hook is elastic in the contact direction of the same, a noise (rebound noise) that occurs when the actuated process input part returns to its original position can be reduced.

[0023] With reference to the accompanying drawings, an input device according to the present invention is described below in reference to an embodiment which is advantageous in conjunction with an electronic device comprising this input device.

[0024] Fig. Figure 1 is a perspective view of an electronic device 12 comprising an input device 10 according to an embodiment of the present invention. The following descriptions are based on the use of the input device 10 as shown in the Fig. In the electronic device 12 shown, for reference the side near the operator is referred to as the front (facing forward), the rear side is referred to as the back (facing backward), the thickness direction of a main housing 14 which forms the electronic device 12 is referred to as the vertical direction, and the width direction of the same is referred to as the horizontal direction.

[0025] As in Fig. As shown in Figure 1, the electronic device 12 is a laptop PC comprising the main housing 14, which includes the input device 10 and a keyboard device 16, and a display housing 18, which includes a display unit 18a, such as a liquid crystal display. The display housing 18 is coupled to the main housing 14 for opening / closing via a pair of left and right hinges 19, 19.

[0026] The main housing 14 internally contains various electronic components, such as a circuit board, a processing unit, a hard disk device, and a memory module, which are not shown. The input device 10 and the keyboard device 16 are located at the front and rear, respectively, on a top surface 14a of the main housing 14. A trackpoint 20 is provided essentially in the center of the keyboard device 16. The trackpoint 20 is used to manipulate a cursor (mouse pointer) displayed on the display unit 18a, serving as an input device that can be used in place of the mouse.

[0027] Although the present embodiment illustrates the configuration in which the input device 10 is built into the electronic device 12, such as a previously mentioned laptop PC, the input device 10 can be built into a keyboard device to form a single unit and to be connected to a desktop PC or the like.

[0028] Next, an example of the configuration of input device 10 will be described. Fig. Figure 2 is a cross-sectional side view that schematically shows the configuration of the input device 10 according to an embodiment of the present invention, and Fig. 3 is a perspective view of the in Fig. 2 of the input device shown 10.

[0029] As in Fig. 1 and Fig. As shown in Figure 2, the input device 10 comprises a touch field (operation input part) 22 for receiving a touch operation from an operator by bringing their fingertip or the like near or into contact with it, and three pushbuttons 24a, 24b and 24c arranged along the part at the rear end of the touch field 22. Fig. 2 and Fig. As shown in Figure 3, the touch field 22 and the push buttons 24a to 24c are held on the side of the top of the base plate 26, which is a metallic plate element.

[0030] Initially, the pushbuttons 24a to 24c function with regard to manipulating the cursor using the trackpoint 20 or the touchpad 22 and are click buttons, each corresponding to a left, middle, and right button of a typical mouse. The pushbuttons 24a to 24c can be located near the front end of the touchpad 22 or can be arranged on a frame of the main housing 14 that lies between the touchpad 22 and the buttons.

[0031] As in Fig. As shown in Figure 2, the pushbuttons 24a to 24c have rear ends 28 that rotatably engage with a retaining piece 30 projecting from the rear end of the base plate 26, allowing these buttons to pivot about the rear ends 28 as a support point. Therefore, when the portion at the front end of each pushbutton 24a to 24c is actuated, a rubber dome 32 located therein is compressed, thereby activating a switch (not shown), such as a membrane switch, provided on the top of the base plate 26.

[0032] Next, the touch field 22 is configured as a click field, which allows a click operation to be performed by pressing in addition to a touch operation.

[0033] As in Fig. As shown in Figure 1, the pseudo-key areas 34a and 34b are configured on a portion of a touch action surface 22a as the surface of the touch field 22 that is close to the front. The pseudo-key areas 34a and 34b each have regions on the touch action surface 22a that are defined by coordinates and are invisible. In response to an actuation of the touch field 22 while a fingertip is brought into contact with one of the pseudo-key areas 34a or 34b, processing or display occurs that corresponds to the pseudo-key area 34a or 34b. For example, the two pseudo-key areas 34a and 34b correspond to the left and right buttons of a typical mouse, respectively.

[0034] As in Fig. As shown in Figure 2, the touch field 22 has a three-layer configuration comprising a receiving plate 40 as a base plate, which is attached to face the base plate 26; a circuit board (printed circuit board) 42, which is layered on top of the receiving plate 40 to detect a touch operation at the touch operation surface 22a; and a field plate (field) 44, which is layered on top of the circuit board 42, the surface of which is the touch operation surface 22a to receive a touch operation. Fig. Figure 3 is missing the illustration of circuit board 42 and field plate 44.

[0035] The circuit board 42 is a printed circuit board having a rectangular shape in plan view, and it is a sensor for detecting a touch operation on the field plate 44 or an actuation operation on the touch field 22. The circuit board 42 is connected to a printed circuit board in the main housing 14 via wiring (not shown). Wiring (not shown) from the pushbuttons 24a to 24c is connected to the circuit board 42. The field plate 44 is a glass or resin plate having a rectangular shape in plan view and is firmly attached to the top of the circuit board 42 by adhesive, double-sided tape, or the like. The circuit board 42 is provided with a ground wire G on its underside near the rear end, the ground wire being a ribbon-like conductive part extending horizontally (see Fig. 2).

[0036] As in Fig. 2 and Fig. As shown in Figure 3, the mounting plate 40 is a resin plate with a rectangular shape in plan view and serves as a housing component to hold the circuit board 42 and the field plate 44. The circuit board 42 is firmly attached to the top of the mounting plate 40 using adhesive, double-sided tape, or the like. The mounting plate 40 has an inclined surface portion 40a at its rear end and near the surface at the forward-facing end of the pushbuttons 24a to 24c, which is inclined downwards towards the rear. This inclined surface portion 40a ensures that the contact area 22 does not obstruct the actuation of the pushbuttons 24a to 24c.

[0037] A pair of left and right elastic pieces 46 are provided on the front of the inclined surface portion 40a of the receiving plate 40 to extend rearward. The elastic pieces 46 are formed by cutting out their two left and right lateral portions and rear portions in the thickness direction to create a piece like a narrow tongue, thus providing a self-supporting structure and allowing for some elasticity. Each elastic piece 46 has a finger 46a at its end (rear end) that can be displaced to be bent downwards.The elastic pieces 46 are not fixed to the underside of the circuit board 42, and at least their fingers 46a are arranged to provide a predetermined gap between their tops and the circuit board 42, whereby projecting pieces 50, formed by cutting the top of the base plate 26 to raise it, as described later, are inserted between the tops of the fingers 46a and the underside of the circuit board 42.

[0038] Furthermore, a plurality of engagement pieces 47 are provided on the front of the inclined surface portion 40a of the receiving plate 40, such that they have a shape essentially similar to that of the fingers 46a of the elastic pieces 46 and extend slightly to the rear. Each of the engagement pieces 47 also engages in the corresponding projecting piece 50, which is cut out to extend from the base plate 26 (see Fig. 2 and Fig. 3).

[0039] Since the elastic pieces 46 and the engagement pieces 47 of the receiving plate 40 rotatably engage with the corresponding projecting pieces 50 of the base plate 26, the receiving plate 40 (contact area 22) can pivot relative to the base plate 26 about these engagement sections as a support point. In the present embodiment, a guide structure (not shown) guides the receiving plate 40 perpendicularly relative to the base plate 26, so that the receiving plate 40 is configured to move perpendicularly while, in effect, it moves the engagement sections of the elastic pieces 46 and the engagement pieces 47 with their corresponding projecting pieces 50 back and forth.

[0040] As in Fig. As shown in Figure 2, a detection switch 55 is provided in a substantially central region on the underside of the receiving plate 40, near the forward-facing end. The detection switch 55 is intended to output a predetermined detection signal when the touch field 22 is actuated. For example, the detection switch 55 is a metal dome switch that curves downward from the underside of the receiving plate 40 and is turned on when the touch field 22 is actuated, until the switch makes contact with the base plate 26 and this ON signal is detected by the circuit board 42.

[0041] As in Fig. As shown in Figure 3, the projecting pieces 50 are formed to extend from the top of the base plate 26. Each projecting piece 50 is formed as an angled U-shape in side view, having a stop plate 50a at its upper end, which is bent backward when a portion of the base plate 26 is cut out to extend upward. A dome-shaped convex element 50b is provided on the top of the stop plate 50a of the projecting piece 50 to arch upward. The projecting pieces 50 are positioned at locations corresponding to the elastic pieces 46 and the engagement pieces 47 of the receiving plate 40. Below these projecting pieces 50, and below the elastic pieces 46, an elastic actuating element 56 is arranged, formed on the top of the base plate 26.

[0042] Fig. 4 is a perspective view showing the main part of the base plate 26 in which Fig. 3 shows input device 10, and Fig. Figure 5 is a perspective view that shows an enlarged view of the main part of the image. Fig. 3 of the input device shown is 10. Fig. Figure 6 schematically shows the main part of the input device 10. Fig. 3, viewed from the back wall, and Fig. Figure 7 is a perspective view showing an enlarged view of the main part of the recording plate 40 in which Fig. The input device shown in section 3 is 10. Fig. Figure 6 shows only a part of the base plate 26 (a first hook 61 and a second hook 62) for better clarity.

[0043] As in Fig. 3 and Fig. As shown in Figure 4, a hook (first hook) 61, which is L-shaped in cross-section on the top of the base plate 26 facing the contact area 22 (process input part), and another hook (second hook) 62 opposite this hook 61 are provided on the base plate 26 of a part near the front end. Two of these first hooks 61 and second hooks 62 are arranged on the left and right sides of the base plate 26 of a part near the front end, with the first hook 61 and the second hook 62 of each pair oriented from front to back (see Figure 4). Fig. 3).

[0044] As in Fig. As shown in Figure 3, a pair of left and right latches 70 are provided on a part near the front end of the receiving plate 40. Each latch 70 has an arm element (first arm element) 71 that can contact the first hook 61, and another arm element (second arm element) 72 that can contact the second hook 62. The latch 70 is essentially V-shaped in plan view and comprises the first arm element 71 and the second arm element 72 (see Figure 3). Fig. 5 and Fig. 6) That is, the first arm element 71 and the second arm element 72 are arranged such that their parts which are located near the forward-facing end are spaced apart from each other.

[0045] This first arm element 71 and this second arm element 72 project in the direction that intersects the functional direction of the actuation process with the contact field 22 and are configured such that their forward-facing ends can each come into contact with the first hook 61 and the second hook 62. The forward-facing ends of the first arm element 71 and the second arm element 72 are each provided with the projecting pieces 71a and 72a, which project in the opposite direction, so that the first hook 61 and the second hook 62 can come into contact with these projecting pieces 71a and 72a.

[0046] In the state where the touch field 22 is not activated, as in Fig. 5 and Fig. As shown in Figure 6, the forward-facing ends of the first hook 61 and the first arm element 71 come into perpendicular contact, thus defining the rising limit of the contact area 22. That is, the first hook 61 and the first arm element 71 are parts that are coupled in the direction in which the receiving plate 40 overlaps the base plate 26.

[0047] Furthermore, in the state where the contact field 22 is not actuated, there is a small gap between the second hook 62 and the second arm element 72, which means that the second hook 62 and the second arm element 72 do not come into contact with each other. That is, the second hook 62 is arranged in a position higher than the first hook 61, so that the former does not come into contact with the second arm element 72 when the contact field 22 is not actuated (see Fig. 9). Thus, the second arm element 72 is configured such that it can come into contact with the second hook 62 in a position above the rise limit of the contact field 22.

[0048] In this embodiment, at least one of the first hook 61 and the first arm element 71 is elastic in the contact direction, and in the present embodiment both the first hook 61 and the first arm element 71 are elastic in their contact direction (vertical direction in Fig. 3) In particular, the first hook 61 has a length from the base end to the forward-facing end that is greater than that of the second hook 62, and the latter has a smaller width, making it elastic in the vertical direction (see Fig. 4) Alternatively, the thickness of the first hook 61 can be reduced, which can increase its elasticity.

[0049] In contrast, the first arm element 71 is made thinner than the second arm element 72 in order to be elastic. In particular, as in Fig. As shown in Figure 7, the first arm element 71 has a thin part 71b which has a thickness L2 that is smaller than the thickness indicated by L3. That is, as in Fig. As shown in Figure 7, the thin part 71b is thinner by the thickness L1 than the second arm element 72.

[0050] In other words, the second hook 62 has a length from its base end to its forward-facing end that is shorter than that of the first hook 61, and it has a greater width, giving the second hook 62 a high stiffness compared to the first hook 61. Furthermore, the second arm element 72 is thicker than the first arm element 71, giving the second arm element 72 a high stiffness compared to the first arm element 71.

[0051] Fig. Figure 8 is a cross-sectional side view that schematically shows the state in which the touch field 22 in the input device 10 is actuated according to an embodiment of the present invention. Fig. Figure 9 is a cross-sectional view along arrow IX-IX from Fig. 5. The upper part of Fig. 9 the state in which the touch field 22 is actuated, and the lower part shows the state in which the actuated touch field returns to its original position (the state in which it is not actuated).

[0052] As in Fig. As shown in Figure 8, when the front part of the touch field 22 is actuated, the touch field 22 rotates relative to the protruding pieces 50, so that the front part of the touch field 22 moves downwards. The detection switch 55 is then actuated, and this actuation is detected by the circuit board 42. As shown in Figure 8, the following processes occur: Fig. 8 and the upper part of Fig. Figure 9 shows that when the touch field is actuated, the first hook 61 and the first arm element 71, which were in contact, separate. The actuated touch field then returns to its original position, and the first hook 61 and the first arm element 71 come back into contact, producing a noise (rebound noise). Since the first hook 61 and the first arm element 71 are elastic in the input device 10, the rebound noise is absorbed by these elastic parts, thus reducing the noise.

[0053] Furthermore, in the input device 10, the second arm element 72 is configured such that it comes into contact with the second hook 62 in a position above the rising limit of the touch field 22. Therefore, contact between the second arm element 72 and the second hook 62 prevents the touch field 22 from detaching from the base plate 26, even if a large force is applied. In other words, this second arm element 72 and this second hook 62 act as a retainer. If, for example, a large force is applied that causes the rising limit of the touch field 22 to be exceeded by the first arm element 71 and the first hook 61, the retainer prevents the touch field 22 from falling off the base plate 26.

[0054] As in Fig.As shown in Figure 9, the second arm element 72 is configured such that it comes into contact with the second hook 62 at a position L4 above the rise limit of the touch field 22. When the actuated touch field 22 of the input device 10 returns to its original position, the first arm element 71 and the first hook 61 come into contact first to reduce rebound noise, and the second arm element 72 and the second hook 62 can then act as a holder.

[0055] Furthermore, the second arm element 72 of the input device 10 has a higher stiffness than that of the first arm element 71, and if a large force is exerted on the touch field 22 and the base plate 26, a contact between the second hook 62 and the second arm element 72, which has this high stiffness, can therefore reliably serve as a holder, thus preventing the touch field 22 from detaching from the base plate 26.

[0056] Furthermore, the second hook 62 of the input device 10 has a higher stiffness than that of the first hook 61, and therefore, if a large force is exerted on the contact field 22 and the base plate 26, a contact between the second arm element 72 and the second hook 62, which has this high stiffness, can reliably serve as a holder, thus preventing the contact field 22 from detaching from the base plate 26.

[0057] Furthermore, the first arm element 71 and the second arm element 72 of the input device 10 project in the direction that intersects with the direction of the actuation process on the contact area 22, thus avoiding an increase in the dimension of the input device 10 in the thickness direction, which means that the input device 10 can be thinner. It should be noted here that the first arm element 71 and the second arm element 72 preferably project in the direction that is substantially orthogonal to the direction of the actuation process on the contact area 22.

[0058] Furthermore, since each bolt 70 is V-shaped and consists of the first arm element 71 and the second arm element 72, the first arm element 71 and the second arm element 72 are forced apart when the first hook 61 and the second hook 62 of the base plate 26 are actuated from below, in order to allow the first hook 61 and the second hook 62 to fit into the bolt 70. The first arm element 71 and the second arm element 72 each have the projecting pieces 71a and 72a at their forward-facing ends, which project in opposite directions. The first hook 61 and the second hook 62 can then each come into contact with these projecting pieces 71a and 72a.

[0059] The present invention is not limited to the embodiments described above and can be freely modified without departing from the spirit of the present invention.

[0060] For example, the embodiment above describes the case where each bolt has a first arm element and a second arm element, and it is possible that the bolt does not have such a second arm element. In this case, the base plate may not have a second hook.

[0061] Alternatively, each bar can have two opposing first arm elements. In this case, these first arm elements can each come into contact with both first hooks, which are elastic.

[0062] The present invention is also applicable to input devices other than a click field, which comprises the touch field 22 that is movably held above the base plate 26.
