Furthermore, when the menu key 117 is used, the menu key 117 is pressed and the metal dome 151 is crushed, whereby a contact operation is performed and a function is selected on the display screen 113 of the housing B112.
- Patent Document 1 It is assumed that the entire disclosed contents of Patent Document 1 are incorporated herein by reference. The following analysis was made by the present inventors. The conventional key structure has the following problems.
- FIG. 6A shows a state when the “5” key of the numeric keypad 116 is input.
- FIG. 6B is a diagram when the “enter” key 121 of the center key 118 is input.
- the user selects a character with the numeric keypad 116 below the center key 118 on the plane of the casing A111, and then moves the thumb on the “OK” key 121 of the center key 118. Let the character be determined. Therefore, the thumb has to be moved by the distance L0 between the “5” key 135 and the “decision” key 121, which makes the input operation difficult and takes time.
- FIG. 7A shows a state when the center key 118 is slid.
- FIG. 7B when the analog pointer 120 of the center key 118 is used, the friction between the thumb and the analog pointer 120 is reduced when the skin of the thumb is dry, for example, in winter. In the state where the contact area between the center key 118 and the tip of the thumb is originally small, the thumb slides on the center key 118 when the frictional force between the thumb that is slidingly operating the center key 118 is further reduced. Therefore, the slide operation of the center key 118 may not be performed well.
- the third problem is that the input operation of the key located at the end is difficult.
- FIG. 8A when an input operation is performed with the index finger hooked on the corner of the casing A111, when the key located at the end is pressed, the thumb does not reach sufficiently and the key is difficult to press.
- FIG. 8B when an input operation is performed with the index finger supporting the lower side of the casing A11, when the key located at the end is pressed, the thumb does not reach sufficiently and the key is pressed. Hateful.
- FIG. 9 is a diagram illustrating an example of a simple solution. Note that FIG. 9A shows a conventional mobile phone.
- FIG. 9B shows a mobile phone in which the arrangement and orientation of the cross key 115, the numeric keypad 116, and the menu key 117 are changed in the conventional mobile phone.
- the cross key 115 is arranged at the center on the plane of the casing A 111, and the menu key 117 is arranged just outside the cross key 115.
- the mobile phone in FIG. 9B has a smaller key area (area where keys are arranged) by (A1 + A2) than the mobile phone in FIG. 9A.
- FIG. 9C shows a mobile phone in which the numeric keypad 116 is downsized and the arrangement of the cross key 115, numeric keypad 116, and menu key 117 is changed.
- the mobile phone in FIG. 9C has a smaller key area by (A1 + A2 + A3 + A4) than the mobile phone in FIG. 9A.
- the key area can be reduced, the ease of pressing the key at the end, and the movement distance of the thumb between the cross key 115 and the numeric keypad 116, respectively.
- the input operation time can be shortened by shortening.
- the effect of improving the operability of the slide operation of the center key 118 cannot be obtained by these mobile phones.
- FIG. 27D shows a state in which a long slide operation is performed while the center key 118 is pressed. If the analog pointer 120 is slid for a long time while pressing the “decision” key 121 of the center key 118, the positions of the protrusion 150 and the metal dome 151 are shifted, and therefore the “decision” key 121 is released.
