DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0013] Figures 1, 2, 3, and 4 are diagrams showing the external configuration of electronic device 10 in this embodiment. Figure 1 is a plan view of electronic device 10 in this embodiment, Figure 2 is a view of electronic device 10 in this embodiment as seen from the underside, Figure 3 is a perspective view of electronic device 10 in this embodiment, and Figure 4 is a view of electronic device 10 in this embodiment as seen from the right side.

[0014] 1, a key input section 11 and a display section 12 are provided on the top surface of the housing of an electronic device 10. The key input section 11 is provided with a plurality of keys 14, a selector switch 15, and the like.

[0015] The multiple keys 14 include, for example, numeric keys, arithmetic keys, and function keys. The numeric keys include, for example, multiple keys corresponding to each of

[00] [0] to [9]. The arithmetic keys include keys used in normal calculations using the four arithmetic operations, such as the [+] (addition) key, the [-] (subtraction) key, the [×] (multiplication) key, the [÷] (division) key, and the [=] (execute operation) key. The function keys include, for example, an all clear key ([AC] key), a clear key ([C] key), multiple memory keys ([MRC][M-][M+]), a root key ([√] key), and a [%] key.

[0016] The selector switch 15 includes, for example, a round selector, a decimal point selector, and the like.

[0017] 1, the exterior shape of the top surface of the housing of electronic device 10 is formed in a substantially rectangular shape. A display unit 12 is provided on the upper side (the upper edge side of the top surface of the housing) of the top surface of the housing, and a key input unit 11 is provided on the lower side (the lower edge side of the top surface of the housing).

[0018] The display unit 12 has a display 16 disposed on a first housing surface 12a, which is a first region (upper side) of the top surface of the housing. The display 16 has, for example, a rectangular display surface extending in the horizontal direction, and is disposed from a first end side (left side in FIG. 1) of the housing to a second end side (right side in FIG. 1) opposite the first end side.

[0019] The key input unit 11 has a plurality of keys 14 (operation units) arranged on a second housing surface 11a in a second region (lower side) of the housing top surface from the first end side to the second end side of the housing. Each of the plurality of keys 14 has an operation surface 14t on its key top. The plurality of keys 14 are arranged at a predetermined interval (key pitch) with a row direction parallel to the top / bottom side of the housing top surface and a column direction parallel to the left / right side of the housing top surface, for example.

[0020] In the electronic device 10 of this embodiment, the second housing surface 11a of the key input unit 11 is formed so that the inclination angle with respect to the placement surface (housing bottom surface) in the direction from the first end side to the second end side, i.e., in the row direction in which the multiple keys 14 are arranged, is a first inclination angle (angle θ). Also, the first housing surface 12a of the display unit 12 is formed so that it is approximately parallel (or approximately horizontal) to the placement surface (housing bottom surface), or so that the inclination angle with respect to the housing bottom surface in the direction from the first end side to the second end side, i.e., in the row direction in which the multiple keys 14 are arranged, is a second inclination angle different from the first inclination angle (angle θ).

[0021] 2 and 4, the second housing surface 11a of the electronic device 10 is inclined at an angle θ relative to the bottom surface 13 of the housing in the row direction in which the keys 14 are arranged. The angle θ is preferably in the range of 1° to 9°, for example. Furthermore, the angle θ is preferably in the range of 1° to 3°, for example (details will be described later; see FIG. 6).

[0022] 1 to 4, the configuration of the electronic device 10 shows an example in which the second housing surface 11a of the key input unit 11 is tilted to the right (the left side is higher than the right side) as shown in FIGS. 2 and 4. That is, at least a portion of the operation surface 14t of the keys 14 (first operation unit) arranged on the first end side (left side) is formed so as to be higher from the placing surface (bottom surface of the housing) than at least a portion of the operation surface 14t of the keys 14 (second operation unit) arranged on the second end side (right side). For example, the center (first center) of the operation surface 14t of the keys 14 arranged on the first end side is formed so as to be higher from the placing surface (bottom surface of the housing) than the center (second center) of the operation surface 14t of the keys 14 arranged on the second end side.

[0023] This configuration provides good operability for the multiple keys 14 when the user of the electronic device 10 operates it with the right hand (right-handed user), and reduces the user's fatigue.

[0024] It is also possible to configure the second housing surface 11a of the key input unit 11 to be tilted leftward, assuming that the user of the electronic device 10 will operate it with their left hand (a left-handed user). That is, at least a part of the operation surface 14t of the keys 14 arranged on the second end side (right side) is formed to be higher from the placement surface (bottom surface of the housing) than at least a part of the operation surface 14t of the keys 14 arranged on the second end side (left side).

[0025] On the other hand, the display surface of the display unit 12 is formed so that the first end side is not higher than the second end side from the placement surface (bottom surface of the housing). In the example shown in Figures 2 and 4, the first end (left side) and the second end (right side) of the display unit 12 are at the same height, and the upper side of the housing top surface is formed to be higher than the boundary part between the key input unit 11 and the display unit 12, and is tilted in the column direction (front-rear direction) in which the multiple keys 14 are arranged.

[0026] 4, the housing of electronic device 10 is bent at the boundary between key input unit 11 and display unit 12, and the position of the upper edge of the housing top surface is raised. As a result, first housing surface 12a of display unit 12 is inclined in the column direction in which multiple keys 14 are arranged, improving the visibility of the display surface of display 16.

[0027] FIG. 5 is a diagram showing an example of a cross section taken along line AA shown in FIG.

[0028] 5, within the housing of the electronic device 10, a substrate 22 is provided so as to be parallel to the second housing surface 11a of the key input unit 11. The substrate 22 is supported by a plurality of support members 24 formed from the bottom portion 13. The substrate 22 supports a plurality of keys 14 within the housing.

[0029] The keys 14 are composed of, for example, a rubber key 21a and key tops 14a1, 14a2, and 14a3. The rubber key 21a is arranged on the upper surface of the substrate 22. The rubber key 21a has rubber key tops 21a1, 21a2, and 21a3 formed at positions corresponding to the key tops 14a1, 14a2, and 14a3 of the multiple keys 14. The rubber key tops 21a1, 21a2, and 21a3 are attached to the corresponding key tops 14a1, 14a2, and 14a3, respectively, so that the keystroke direction is perpendicular to the second housing surface 11a.

[0030] Openings corresponding to the multiple keys 14 are formed in the second housing surface 11a. The openings are formed so that the opening surfaces are substantially perpendicular to the substrate 22, and the angle between the opening surfaces and the second housing surface 11a is substantially perpendicular. Key tops 14a1, 14a2, and 14a3 pass through the corresponding openings, and their operation surfaces 14ta1, 14ta2, and 14ta3 are supported at positions higher than the second housing surface 11a. Therefore, the side surfaces of the key tops 14a1, 14a2, and 14a3 face the opening surfaces of the openings with a small gap that allows them to move substantially parallel to each other.

[0031] The rubber key tops 21a1, 21a2, and 21a3 are normally attached to the board 2 in order to provide a clicking sensation when the key tops 14a1, 14a2, and 14a3 attached to the top of each are pressed. 2 When pressed down, the substrate 2 2 The rubber key tops 21a1, 21a2, and 21a3 are provided with conductive members at their bottoms, and when the rubber key tops 21a1, 21a2, and 21a3 are pressed down by pressing the key tops 14a1, 14a2, and 14a3, they come into contact with electrodes wired to the substrate 22 to detect the key press.

[0032] 5, operation surfaces 14ta1, 14ta2, and 14ta3 (top surfaces) of keytops 14a1, 14a2, and 14a3 are formed so as to be parallel to bottom surface 13. That is, when electronic device 10 is placed on a horizontal surface, operation surfaces 14ta1, 14ta2, and 14ta3 of keytops 14a1, 14a2, and 14a3 are horizontal. Also, heights L1, L2, and L3 of keytops 14a2 and 14a3 decrease in this order from keytop 14a1 on the first end side to keytops 14a2 and 14a3 on the second end side.

[0033] The key tops 14a1, 14a2, and 14a3 are formed in the same shape, and the stroke length defined by the movable range of the rubber key tops 21a1, 21a2, and 21a3 is the same, so that the heights L1, L2, and L3 relative to the bottom surface 13 are stepped according to the inclination angle θ of the second housing surface 11a, as shown in Figures 2 and 3.

[0034] As shown in Figures 2 and 4, in the electronic device 1 of this embodiment, the second housing surface 11a of the key input unit 11 is inclined at an angle θ in the row direction of the keys 14 with respect to the bottom surface 13, and the operation surfaces 14t of the keys 14 arranged on the first end side are formed to be higher than the operation surfaces 14t of the keys 14 arranged on the second end side, thereby improving operability of the keys 14 and reducing user fatigue.

[0035] Fig. 6 is a diagram showing the results of measuring the amount of muscle activity of a user when the second housing surface 11a of the key input unit 11 is tilted in the row direction of the key arrangement. Fig. 6 targets the pronator teres muscle, and shows the results compiled based on the measurement values ​​of the electromyograph when key operations are performed with the electromyograph attached to the position of the pronator teres muscle on the arm.

[0036] 6 shows the average of the measurement values ​​measured for a plurality of subjects at each angle while changing the inclination angle θ of the second housing surface 11a of the key input unit 11 in 1° increments within the range of 0° to 9°. In addition, in order to show the relative relationship of the measurement values ​​(amount of muscle activity) at each angle, the measurement value when the angle θ is 0° is set to 100%, and the measurement values ​​for other angles of 1° to 9° are normalized.

[0037] As shown in Figure 6, it was detected that the larger the angle θ, the less muscle activity the user experiences when operating the keys. In other words, by tilting the second housing surface 11a of the key input unit 11 in the row direction of the keys, the user is less likely to get tired than when the second housing surface 11a is not tilted in the row direction of the keys.

[0038] Furthermore, when measuring the orientation of the subjects' palms while operating the keys, it was confirmed that the palms of almost all subjects were tilted to the right relative to the horizontal plane (when operating the keys with the right hand). Specifically, the palms were tilted to the right by an angle ranging from 5° to 13°.

[0039] Therefore, by tilting the second housing surface 11a of the key input unit 11 in the row direction of the arrangement of the keys 14, i.e., to the right, the direction of the palm of the user's hand when operating the keys and the second housing surface 11a will be opposite to each other without a large difference in inclination, thereby improving the operability of the keys 14.

[0040] As shown in Figure 6, the larger the angle θ, the less muscle activity the user experiences when operating the keys. However, a larger angle θ may cause discomfort for users who are accustomed to operating existing electronic devices (calculators) whose keys are not tilted to the right. Therefore, it is preferable to set the angle θ in the range of 1° to 3° to improve operability and reduce fatigue in key operation without causing discomfort to the user.

[0041] Furthermore, in the electronic device 10 of this embodiment, the key input unit 11 is tilted to the right and the top surfaces of the keys 14 are formed horizontally. Therefore, users who are accustomed to operating keys on existing electronic devices (calculators) with horizontally formed top surfaces of the keys can operate the keys without feeling uncomfortable.

[0042] In the configuration shown in FIG. 5, the top surfaces of the key tops 14a1, 14a2, and 14a3 are formed horizontally (parallel to the bottom surface 13), but the top surfaces of the key tops may have other shapes.

[0043] Fig. 7 is a diagram showing an example of a cross-sectional view when the shape of the top surface of the key top is changed, taken along line AA shown in Fig. 1. Fig. 7 has the same configuration as Fig. 5 except for the operation unit, and detailed description thereof will be omitted.

[0044] In the example shown in Figure 7, the rubber key tops 21b1, 21b2, and 21b3 of the rubber key 21b, which is formed in the same manner as the rubber key 21a shown in Figure 5, are attached to the corresponding key tops 14b1, 14b2, and 14b3 so that the key stroke direction is perpendicular to the second housing surface 11a.

[0045] 7, operation surfaces 14tb1, 14tb2, and 14tb3 (top surfaces) of the key tops 14b1, 14b2, and 14b3 are formed so as to be parallel to the second housing surface 11a of the key input unit 11. That is, the top surfaces of all the key tops 14b1, 14b2, and 14b3 are parallel to the second housing surface 11a of the key input unit 11, and the heights L from the second housing surface 11a are the same.

[0046] Therefore, in the configuration shown in Figure 7, users who are accustomed to operating the keys on existing electronic devices (calculators) in which the operating surface (top surface) of the key top is formed parallel to the second housing surface 11a of the key input unit 11 can operate the keys without feeling uncomfortable.

[0047] When keys of the electronic device 10 are operated with the right hand, the electronic device 10 is often placed on the right side of the user rather than directly in front of the user. In the electronic device 10 of this embodiment, the second housing surface 11a of the key input unit 11 is tilted to the right, thereby improving operability, while the first housing surface 12a of the display unit 12 is tilted in the column direction of the key arrangement without being tilted to the right in accordance with the second housing surface 11a, thereby ensuring visibility of the display 16.

[0048] Therefore, in the electronic device 10 of this embodiment, visibility of the display 16 is ensured, and the keys 14 are easy to operate, so that the user does not get tired easily.

[0049] In the configuration shown in Figures 1 to 4, the first housing surface 12a of the display unit 12 is inclined so that the position of the upper edge side of the housing top surface is higher, thereby improving the visibility of the display surface of the display 16. However, as shown in Figure 8 or Figure 9, the inclination state of the first housing surface 12a can be configured in a different way.

[0050] Fig. 8 is a view from the right side of the electronic device 10 according to this embodiment, in which the first housing surface 12a of the display unit 12 is modified. In the configurations shown in Figs. 1 to 4, the display unit 12 has the upper edge of the housing top surface higher than the boundary between the key input unit 11 and the display unit 12, so that the display surface of the display 16 is inclined, but in the configuration shown in Fig. 8, the display surface of the display 16 is formed to be approximately horizontal (approximately parallel to the bottom surface of the housing).

[0051] In the example shown in FIG. 8, the left and right sides of the top surface of the housing of the key input unit 11 and the first housing surface 12a of the display unit 12 are formed to be parallel to each other.

[0052] That is, the display surface of the display 16 provided on the display unit 12 is formed to be nearly horizontal (substantially parallel to the bottom surface of the housing), improving the visibility from above the electronic device 10. For example, when a user uses the electronic device 10 by placing it close to the body, the visibility of the display 16 from above the electronic device 10 is improved, and operability can be improved by tilting the second housing surface 11a of the key input unit 11 to the right.

[0053] FIG. 9 is a view of the electronic device 10 of this embodiment, viewed from the underside, showing a modified first housing surface 12a of the display unit 12. In FIG.

[0054] 9, the first housing surface 12a of the display unit 12 is tilted in the direction opposite to the direction in which the second housing surface 11a of the key input unit 11 is tilted. That is, the second housing surface 11a of the key input unit 11 is tilted to the right in the row direction of the plurality of keys 14, and the first housing surface 12a of the display unit 12 is tilted to the left in the row direction of the plurality of keys 14.

[0055] That is, when keys are operated with the right hand, the electronic device 10 is often placed on the right hand side rather than directly in front of the user, and therefore, in this embodiment, the second housing surface 11a of the key input unit 11 is tilted to the right to improve operability, while the first housing surface 12a of the display unit 12 is tilted to the left, opposite to the second housing surface 11a, thereby further improving the visibility of the display 16 compared to when the first housing surface 12a is tilted only in the column direction (front-to-back direction) in which the keys 14 are arranged, as shown in FIG. 2.

[0056] Furthermore, it is possible to improve the visibility of the display 16 not only by tilting the first housing surface 12a of the display unit 12 to the left, but also by forming the first housing surface 12a so that the position of the upper edge of the housing top surface is higher.

[0057] In this way, the electronic device 10 of this embodiment ensures visibility of the display 16, and also makes it possible to improve the operability of the keys 14 and reduce fatigue for the user.

[0058] In the above description, when it is assumed that the user operates the electronic device 10 with the left hand (a left-handed user), the second housing surface 11a of the key input unit 11 is configured to be tilted leftward in the row direction of the arrangement of the multiple keys 14. In addition, by configuring the electronic device 10 in the left-right direction in the opposite direction to the configuration when the user uses the electronic device 10 with the right hand (right-handed), it is possible to realize an electronic device 10 that ensures visibility of the display 16 for left-handed users, has good operability for the keys 14, and reduces user fatigue.

[0059] The present invention is not limited to the embodiments, and various modifications can be made in the implementation stage without departing from the gist of the invention. Furthermore, the embodiments include inventions at various stages, and various inventions can be extracted by appropriately combining the disclosed multiple constituent elements.
