`
`Abstract
`
`PROBLEM TO BE SOLVED: To improve operability, to make a design to be clean-cut, to improve the
`strength of a casing case and to improve the formability of the casing. SOLUTION: A rst easing 1, a
`second casing 2, a rocking axis 7 connecting the rst easing 1 and the second easing 2 so that they
`can rock and a key 4 arranged on the rocking axis 7 are installed. A rst face 8 that the rst casing 1
`has and a second face 9 that the second casing 2 has can be folded so that they are almost
`matched. The key 4 can be turned with a turning axis 13 as a center and the key 4 outputs a rotating
`direction. The number of keys arranged on the surface of the casing is reduced and the area of the
`opening part of the casing becomes small. The turning axis 13 is almost matched with the rocking
`axis 7. The key 4 can move in parallel to a direction 15 vertical to the turning axis 13 and it outputs
`on or off based on parallel movement. In the folded state, the key 4 is exposed to an outer part and a
`user can operate the key 4. A display part 19 is included in a third face 18 exposed to the outer part.
`When the key 4 is operated in the folded state, an operation situation is displayed on the display part
`19.

`[0012]
`
`DESCRIPTION OF THE PREFERRED EMBODIMENTS Corresponding to the drawings, an embodiment of a foldable portable communication device according to the
`present invention is formed of a display-side housing and a button-side housing, and is rotated by a hinge portion connecting these. An expression scroll key is provided.
`The display-side housing 1 has a display side surface 8 as shown in FIG.
`The display section 5 is provided on the display side surface 8. Button side housing 2
`Has a button side surface 9 and a plurality of key buttons 6 on the button side surface 9. The display-side housing 1 is a button-side housing 2
`Are pivotally connected around a shaft 7 of the hinge portion 3. The portable communication device 10 includes a display side surface 8 of the display side housing 1.
`And the button side surface 9 of the button-side housing 2 can be folded so as to substantially overlap with each other. Rotary scroll key 4
`Are arranged on the hinge part 3.
`
`FIG. 2 shows a cross section of the portable communication device 10. The display side housing 1 has a printed circuit board 11 inside. The button-side housing 2 has a
`printed circuit board 12 inside. The printed board 11 and the printed board 12 are electrically connected to each other by a exible printed board or a cable (not shown) in
`order to perform the function of the portable communication device 10.
`
`The rotary scroll key 4 has a rotating shaft 13, and has two rotating directions 1 around the rotating shaft 13.
`4 is rotatable. The rotating shaft 13 is a shaft 7 of the hinge 3
`It is generally consistent with. The rotary scroll key 4 is electrically connected to the printed board 11 or the printed board 12. The rotary scroll key 4 outputs the rotation
`direction and the rotation angle rotated by the user to the printed board 11 or the printed board 12. The rotary scroll key 4 has a switch unit 16. The rotary scroll key 4 can
`be pressed in a direction 15 that is substantially perpendicular to the rotation axis 8 and substantially perpendicular to the display side surface 8 or the button side
`surface 9. The switch unit 16 outputs ON or OFF based on whether or not the rotary scroll key 4 is pressed in the direction 15.
`
`By providing the rotary scroll key 4 on the hinge part 3, the number of key buttons 6 arranged on the button side surface 9 of the button side housing 2 is reduced. The
`reduction in the number of key buttons 6 simplies the design of the portable communication device 10,
`The opening of the case of the button-side housing 2 is reduced. The reduction of the case opening improves the strength of the case. The case is manufactured by die
`molding. The reduction in the opening of the case further improves the owability of the raw material during the molding of the case and improves the formability.
`
`The function of the foldable communication device 10 is executed by menu selection using the rotary scroll key 4. A list of a plurality of items corresponding to the
`functions of the foldable communication device 10 is displayed on the display unit 5, and one of the items is selectively displayed so as to be distinguishable from other
`items. When the rotary scroll key 4 is rotated, the item selected and displayed changes according to the rotation angle. Rotary scroll key 4
`Is pressed in the direction 15, the item selected and displayed is determined, and the function corresponding to the determined item is executed.
`
`The rotary scroll key 4 is used for scrolling information displayed on the display unit 11. The information is exemplied by a telephone number, an address book, and the
`like. When the rotary scroll key 4 is rotated, the displayed information is scrolled according to the rotation angle.
`
`With the button-type scroll key, the user must press the key several times to change the item. The rotary scroll key 4 allows the user to select an item only by rotating it
`with his / her nger, which is convenient.
`
`In another embodiment of the foldable portable communication device according to the present invention, a rotary scroll key can be used in a folded state. As shown in
`FIG. 3, the rotary scroll key 4 is exposed to the outside when the foldable portable communication device 10 is folded. Surface 1 of display side housing 1

`
`8 is provided with an LED 19. The surface 18 is a surface on the opposite side of the display side surface 8 of the display side housing 1.
`
`When the rotary scroll key 4 is rotated with the foldable portable communication device 10 folded, the foldable portable communication device 10 has functions required
`in the folded state, such as adjustment of ringtone volume and sensitivity adjustment. Works. LED1
`3 emits light based on this operation, blinking interval, color tone,
`Alternatively, the user is notied of the operation status of the function by a change in illumination luminance. A liquid crystal display screen may be provided instead of
`the LED 19. In this case, the liquid crystal display screen displays the function in the folded state, and executes the function by selecting a menu.
`
`In still another embodiment of the foldable portable communication device according to the present invention, a slide type scroll key is provided on a hinge portion. The
`sliding scroll key 2
`1 has a rotating shaft 23, which substantially coincides with the shaft 7 of the hinge 3. The sliding scroll key 21 has two rotation directions 2 around a rotation axis 23.
`4 and does not rotate more than a predetermined angle from the initial angle. The user can slide the scroll key 21
`When the swing is stopped and the swing is stopped, the slide type scroll key 21 returns to the initial angle. The slide type scroll key 21 is electrically connected to the
`printed board 11 or the printed board 12. Sliding scroll key 21
`Indicates the rotation direction rotated by the user
`1 or output to the printed circuit board 12.
`
`The slide type scroll key 21 has a switch unit 26. The sliding scroll key 21 is substantially perpendicular to the rotation axis 23 and
`Alternatively, it can be pressed in a direction 25 substantially perpendicular to the button side surface 9. The switch unit 26 outputs ON or OFF based on whether or not
`the slide type scroll key 21 is pressed in the direction 25.
`
`In the menu selection, the item selected and displayed changes as the slide type scroll key 21 is swung. If the slide type scroll key 21 has not returned to the initial angle,
`the selected and displayed item changes continuously. When the slide type scroll key 21 returns to the initial angle, the change of the item ends. When the slide type
`scroll key 21 is pressed in the direction 25, the item selected and displayed is determined, and a function corresponding to the determined item is executed.
`
`[0024]
`
`The foldable portable communication device according to the present invention has the following features.
`The scroll keys are arranged on the hinge portion, and the number of key buttons arranged on the housing surface is reduced. The reduction in the number of key buttons
`simplies the design and reduces the number of openings in the housing case. The reduction in the opening of the case improves the strength of the case, improves the
`uidity of the material when forming the case, and improves the moldability.
