  Each rib of the first rib 111 and the second rib 121 includes a rail-like member formed continuously in the longitudinal direction in the vicinity of both side surfaces on the inner surface of the housing. In addition, each rib 111, 121 is formed by connecting two rail-like members provided in the vicinity of both side surfaces of one housing at the front end portion of the housing, and forming a U-shape on the inner surface of the housing as a whole. The ribs 111 and 121 are formed so as to be continuous. The cross sections of the ribs 111 and 121 are continuously formed so as to have a substantially U-shaped cross section covering the display surface side periphery from the outside of the display 160, that is, an open shape for receiving the display 160. And the rib is not provided in the area | region of the hinge side edge part of a housing | casing inner surface, The hinge side and termination | terminus part of a rib are comprised with the open shape of the substantially U-shaped cross section being maintained.

  The height of each rib (the first rib (first guide portion) 111 and the second rib (first guide portion) 121) is such that the front end of the display 160 can be inserted from the end portion on the hinge 170 side when the mobile phone 100 is assembled. In addition, the height of the open shape of the cross section is configured to be equal to or slightly larger than the thickness of the display 160. Thereby, the display 160 inserted in each rib 111,121 cannot move easily with respect to the longitudinal direction and the lateral direction of the casing. In FIG. 1, the display 160 inserted in each rib is shown in a dotted line frame. Further, one end of the display 160 in the longitudinal direction and the opening / closing axis direction is covered by the ribs 111 and 121, and the other display 160 is shown by a linear rectangle. Accordingly, the display 160 can move in a direction parallel to the opening / closing axis without bonding the display 160 to the inner surface of each housing, and from the housing in a direction perpendicular to the inner surface of each housing. Can be prevented from leaving.

  The display 160 is restricted from moving in the thickness direction of the casing in the vicinity of the center portion of each casing fixed by the ribs 111 and 121, but the hinge 170 is not fixed by the ribs 111 and 121. In the vicinity, movement in the thickness direction is possible in a substantially semicircular region according to the opening and closing of the housing. In FIG. 1, the part (variable part 161) which is not fixed by each rib of the display 160 is shown by the hatched part in a frame.

  As will be described later, since the material of the display 160 is made of a flexible material, the variable unit 161 can be bent or deformed according to the opening / closing of the housing.

  A first fixing pin (first fixing member) 112 is provided on the first casing side and a second fixing pin (second fixing member) 122 is provided on the second casing side at the end portion of the rib of each casing. ing.

  Each casing is provided with two fixing pins (first fixing pin 112 and second fixing pin 122), and they are located at a predetermined interval in parallel with the lateral direction of each casing. .

  The display 160 includes a flexible display member (flexible display) such as an organic EL display (Organic Electro Luminescence Display) or electronic paper. From the above configuration, the display 160 can be bent or deformed, and is formed so as not to be easily torn. Note that the display 160 may be made of any material as long as it can be bent, and is not limited to the above-mentioned display.

  In the display 160, a connection portion 162 is formed on the back surface of the second housing 120 on the second fixing pin 122 side end portion. As will be described later, the connection unit 162 connects the circuit board 130 and the battery 150 provided in the second housing 120 and the display 160 via a supply line. With the above configuration, the display 160 arranged across the first housing 110 and the second housing 120 is separated from the circuit board 130 and the battery 150 via the connection portion 162 provided on the second housing 120 side.

  Since the connecting portion 162 is formed on the back surface of the display 160 so that the width in the short direction is shorter than the terminal portion of the second rib 121, the entire surface is covered with the second rib 121 and exposed to the outside as shown in FIG. do not do.

  In FIG. 1, the display 160 is shown in a dotted frame, and the portion exposed to the outside without being covered by the ribs 111 and 121 is shown in a straight frame.

  Further, the display 160 does not have to be arranged on almost the entire inner surface of the first casing 110 and the second casing 120 in the closed state as shown in FIG. Any size may be used as long as it is continuously provided on the hinge 170 side of the body 120. Further, the length of each rib in the longitudinal direction and the position in the lateral direction may be changed as the width of the display 160 in the longitudinal direction and the lateral direction changes.

  Further, as shown in FIG. 2, the hinge connection end of the inner surface of the first housing 110 has a storage portion (concave portion) 114 that is stored in a state where the variable portion 161 of the display 160 is deformed when the housing is closed. And a sponge (elastic member) 115 filled in the storage part (recessed part) 114 is provided.

  The storage part (recessed part) 114 is provided at the hinge connection end on the inner surface of the first casing 110 and has a configuration that opens in the longitudinal direction of the first casing. Further, the width in the short direction of the storage portion (recessed portion) 114 is equal to or larger than the width in the short direction of the display 160. In order to have the above configuration, the variable portion 161 of the display 160 is folded and stored in the storage portion (concave portion) 114 when the housing is closed. Details of the storage state of the variable portion 161 in the storage portion (recessed portion) 114 will be described later with reference to FIG.

  The sponge (elastic member) 115 is filled in the storage portion (recessed portion) 114 described above, and a part of the surface is exposed to the outside. The exposed surface of the sponge (elastic member) 115 is indicated by a hatched portion in FIG.

  The sponge (elastic member) 115 is supported in the opening direction of the housing in a state where the back surface of the variable portion 161 of the display is in contact with the exposed surface when the housing is in the open state. Even when the housing is in the closed state, the opening direction of the housing is still in contact with the back surface of the variable portion 161 of the display 160 when the variable portion 161 of the display 160 is deformed and stored in the storage portion (recessed portion) 114. To support.

  Details of the sponge (elastic member) 115 will also be described later.

  Next, FIG. 3 is a cross-sectional view taken along the line AA ′ in the opened state of the mobile phone 100 according to FIG.

  As shown in FIG. 3, each fixing pin (first fixing pin 112, second fixing pin 122) described above is formed in a convex shape. When the mobile phone 100 is assembled, the first fixing pin 112 passes through a part of the display 160 inserted into the first rib 111 and is inserted into the first hole 116 formed perpendicular to the thickness direction of the first housing 110. Is done. Similarly to the first fixing pin 112 described above, the second fixing pin 122 penetrates a part of the display 160 inserted into the second rib 121 and is vertically formed in the thickness direction of the second housing 120. The two holes 125 are inserted.

  With the above configuration, the display 160 is restricted from moving in the longitudinal direction and the lateral direction with respect to the first casing 110 and the second casing 120. Furthermore, when the configurations of the ribs are combined, the display 160 is restricted from moving in each direction with respect to the casing except for the variable portion 161. For this reason, it is possible to prevent the occurrence of bending or distortion other than the variable portion 161 of the display 160.

  Further, as shown in FIG. 3, the storage portion (concave portion) 114 formed on the inner surface on the first housing 110 side has an opening structure that opens in the longitudinal direction, and the opening structure allows the mobile phone 100 to be opened from the side surface side. The section is U-shaped. The storage portion 114 has a top surface in the thickness direction that is inclined with respect to the inner surface of the first housing, and the inclined surface supports a part of the back surface of the variable portion 161 of the display 160 in the opening direction of the housing. ing. With the above-described configuration, since the variable portion 161 of the display 160 is substantially parallel to the display 160 disposed in the second housing 120, no fold is generated.

  The sponge (elastic member) 115 housed in the housing part (concave part) 114 is formed in the shape of a trapezoidal pillar having an inclined surface of about 30 degrees with respect to the inner surface of the first housing 110, and the inclined surface is a housing. It is exposed to the outside in the longitudinal direction of the body and is stored in the storage portion (recessed portion) 114.

  In addition, since the angle of the inclined surface of the sponge 115 is formed at an angle substantially equal to the inclined surface of the top surface in the thickness direction of the storage portion 114, an angle other than the above may be used.

  The sponge (elastic member) 115 has a cushioning property that can be easily bent and contracted, and is formed of a material such as rubber having a stress smaller than that of the variable portion 161 of the display 160. Therefore, the sponge (elastic member) 115 is pressed to reduce the shape when the cellular phone 100 is assembled, and is sandwiched between the upper end and the lower end in the thickness direction of the storage portion 114, so that the inside of the storage portion (recess portion) 114. It is filled without gaps. With the above-described configuration, it is possible to prevent dust and dust from entering the storage portion (recessed portion) 114.

  The sponge (elastic member) 115 supports the display 160 in the opening direction of the housing in a state where the display 160 is in contact with the back surface of the variable portion 161. Therefore, even if the case is maintained in the open state and a force in the opening direction of the case is applied due to an unexpected impact, the case can be prevented from being easily closed.

  Next, an inclined surface 124 is formed in the second casing 120 so as to face the first casing 110 at the end on the second hinge 123 side. The inclined surface 124 supports the back surface of the variable portion 161 of the display 160 in the opening direction of the housing.

  The hinge 170 is formed on the display 160 side on both side surfaces of the storage portion 114 of the first housing 110. Therefore, when the first housing 110 and the second housing 120 are in the open state, a part of the first hinge side end portion of the outer surface of the first housing 110 falls with respect to the second housing 120. In addition, when each case rotates from the closed state and the angle α formed by the cases becomes equal to or greater than a certain value, the end on the first hinge 113 side of the first case 110 becomes the end of the second case 120. Contacting the second hinge side end, further rotation of each casing is restricted. As a result, the hinge 170 constituting the opening / closing mechanism having the above-described configuration prevents the display 160 from being broken or cracked by the rotation of each casing at a certain angle or more.

  However, the open angle of each of the casings 110 and 120 is not limited to the angle α shown in FIG. 3, and the first casing 100 and the second casing can be changed by changing the configuration of the hinge 170 described above. It is possible to adjust the angle at which 120 is opened, and to realize an angle in an open state in which the display becomes flat as a whole.

  As shown in FIG. 3, a touch sensor 140, a circuit board 130, and a battery 150 that are superimposed on the display 160 are installed inside the second housing 120.

  Further, as described above, the display 160 is provided with the connection portion 162 that receives signals and power from the circuit board (control portion) 130 and the battery 150. Although not shown in the drawing, the supply line connecting between the circuit board 130 and the battery 150 and the connection portion 162 is connected to the display 160 through a hole provided in the vicinity of the second hole 125 of the second housing 120. Connected to the unit 162. The supply line is arranged in a gap such as a circuit board inside the second housing 120. Therefore, by installing the connection portion 162 of the display 160 on the second housing side, the circuit board 130, the battery 150, and the supply line are concentrated inside the second housing 120 and supplied to the hinge 170 and the first housing 110. There is no need to provide a structure for passing the wire. Thereby, the internal structure of the hinge 170 and the first housing 110 is simplified, and the thickness of the mobile phone 100 can be reduced as a whole by reducing the thickness.

  The touch sensor 140 is provided adjacent to the circuit board 130 and the battery 150 in the second housing 120 on the display 160 side on the surface of the second housing 120. Regarding the display control of the display screen by the touch sensor 140, first, when the contact of the finger or the touch pen with the display 160 is detected, a finger detection signal is transmitted from the touch sensor 140 to the control circuit in the circuit board 130, and from the control circuit. By transmitting an image control signal corresponding to the detection signal from the connection unit 120 to the display 160, a display screen corresponding to the detection of the touch sensor 140 is displayed on the display 160. For example, letters and numbers keys are displayed on the display 160 on the second housing 120 side, and a display screen such as an application is displayed on the display 160 on the first housing 110 side. When the displayed character or numeric key is touched with a finger, the touch sensor 140 detects the touch of the finger, and the screen displayed on the display 160 on the first housing 110 side changes according to the operation.

  The circuit board 130 has a control circuit in which various circuit components such as a memory and a CPU are incorporated, and realizes image display control of the display 160, battery power supply control, and the like. Further, as described above, the circuit board 130 is installed in the second housing 120 and is connected to the display connection portion 162 via the supply line to supply a signal to the display 160.

  Further, the circuit board 130 incorporates a small microphone for realizing a telephone function, a small sound generator, and a circuit driving battery 150.

  The battery 150 is installed inside the second housing 120, and is connected to the circuit board 130, the touch sensor 140, and the display 160 via a supply line. Further, by using a battery 150 that does not easily damage other members such as an elastomer, it is possible to prevent the adjacent circuit board 130 and the inner surface of the second casing 120 from being damaged.

  Although not shown in the drawing, a battery housing part for housing the battery 150 and a battery lid for removing the battery from the housing are formed on the outer surface and the side surface of the second housing 120. .

  Next, FIG. 4 is a cross-sectional view taken along the line BB ′ in the opened state of the mobile phone 100 according to FIG.

  As shown in FIG. 4, a first rib 111 is provided on the side surface of the first casing 110 so as to extend inward in the lateral direction of the housing. The first rib 111 is in contact with a part of the top surface and the side surface of the display 160 on the inner surface, and is formed so as not to cause a gap for the display 160 to move inside the housing. Therefore, the display 160 is restricted from moving in the thickness direction and the lateral direction of the housing by the first ribs 111, and can prevent the occurrence of bending or distortion.

  Next, FIG. 5 is a cross-sectional view taken along the line AA ′ in the closed state of the mobile phone 100 of FIG.

  As shown in FIG. 5, the inclined surface (inclined portion) 124 configured at the hinge side end portion of the second housing 120 is a sponge (elastic member) stored in the storage portion (recessed portion) of the first housing 110. ) 115 is formed to face the exposed surface.

  The first fixing pin 112 and the second fixing pin 122 protrude from the inner surfaces of the first casing 110 and the second casing 120, and elastic damper rubber (elastic material) is formed. When the first fixing pin 112 and the second fixing pin 122 face each other in the closed state, the damper rubber (elastic material) comes into contact. With the above-described configuration, it is possible to prevent the first housing 110 and the inner surface of the second housing 120 or the displays 160 arranged in the respective housings from being brought into contact with each other, and reduce the impact generated in each housing.

  The variable portion 161 of the display 160 is bent gradually so that the central portion protrudes in the longitudinal direction on the hinge 170 side of the casing as the casing angle α decreases from the opened state of the casing. The deformable variable portion 161 is accommodated in the accommodating portion 114 from the vicinity of the central portion, and is deformed by pressing the accommodated sponge (elastic member) 115. When the angle α of the housing becomes zero and the housing is completely closed, the variable portion 161 bends into a cylindrical shape, and almost all is housed in the housing portion 114 and the sponge 115 is pressed. Reduce to less than half the size.

  It should be noted that when the casing is in a closed state, bending stress generated when the variable portion 161 of the display 160 is bent into a cylindrical shape, and elastic stress generated when the sponge (elastic member) is deformed by the variable portion 161 of the display 160 are provided. It occurs in the opening direction of the body. Therefore, although not shown in the figure, in order to prevent the casing from automatically shifting to the open state due to the stress described above, each fixing pin (first fixing pin 112, second fixing pin 122) In addition to the above-described damper rubber, magnets having different polarities may be provided.

  6 is an enlarged view of the vicinity of the hinge 170 in FIG. 3, and FIG. 7 is an enlarged view of the vicinity of the hinge in FIG.

  As shown in FIG. 6, the inclined surface 124 of the second housing 120 is composed of two inclined surfaces, a first inclined surface 124a and a second inclined surface 124b. The first inclined surface 124a is positioned closer to the hinge 170 than the second inclined surface 124b, and is formed at a smaller angle with respect to the surface other than the inclined surface of the second housing 120.

  The first rib 111 is formed in an arc shape in the thickness direction in the vicinity of the storage portion 114 and is formed so that the end portion on the hinge side 170 is the highest. Further, since the first rib 111 is formed in the vicinity of the storage portion 114 so as to face the exposed surface of the sponge 115, the surface of the variable portion 161 of the display 160 is defined by the first rib 111. The back surface is supported by the inclination of the sponge 115 and the storage portion 114. Therefore, the variable portion 161 can prevent the bending and the separation from the storage portion 114 and the sponge 115 on the first housing 110 side.

  In addition, the first housing 110 has a recess formed on the inner surface where the display 160 is disposed, in accordance with the shape of the first rib 111 facing each other.

  The second rib 121 is inclined in the vicinity of the first inclined surface 124a so as to face the first inclined surface 124a.

  In the open state, the angle of the end of the first rib 111 on the hinge 170 side with respect to the inner surface of the second housing 120, the angle of the first inclined surface 124a of the second rib 121, and the sponge (elastic member) 115 The angle of the exposed surface and the inclination angle of the storage portion 114 are all substantially equal. For this reason, the vicinity of the variable portion 161 of the display 160 is substantially flat and is not bent, so that it is possible to prevent the user from being uncomfortable in viewing the screen.

  Next, as shown in FIG. 7, the first casing 110 and the second casing 120 face each other in the closed state, and the first rib 111 and the second rib 121 have a certain gap. Facing each other. At this time, since the damper rubber provided on the first fixing pin 112 and the second fixing pin 122 contacts with each other, the first casing 110 and the second casing 120, the first rib 111 and the second rib 121. Do not contact each other, and a certain gap is generated in the thickness direction.

  Further, the second rib 121 is formed with an end portion up to the vicinity of the intermediate portion of the first inclined surface 124a. Therefore, it is possible to prevent the first rib 111 and the second rib 121 from coming into direct contact with each other when the housing is in the closed state. The first rib 111 includes the variable portion 161 of the display 160 and the second inclined portion 124b. 161 is supported in a direction opposite to the direction in which 161 is supported. Therefore, when the housing is in the closed state, the variable portion 161 can be maintained in a cylindrical shape and can be prevented from being bent at a steep angle.

  Further, the first inclined surface 124a is formed in parallel to the recess of the inner surface of the first housing 110 described above, and the variable portion 161 of the display 160 is directed obliquely with respect to the inner surface of the second housing 120. Therefore, it is possible to realize a symmetrical cylindrical shape and prevent a sharp bend.

  The variable portion 161 of the display 160 is housed in the housing portion (concave portion) 114 by deforming the sponge (elastic member) 115 by pressing. Since the storage part (recessed part) 114 is formed with a larger width in the thickness direction than the variable part 161, it is possible to prevent the bending due to the variable part 161 coming into contact with the storage part (recessed part) 114.

  In the above-described embodiment, the connection unit 162, the circuit board 130, the battery 150, and the touch sensor 140 are provided on the second housing 120 side, but these may be all provided on the first housing 110 side. Good. Further, the form of each casing (the first casing 110 and the second casing 120) is not limited to the present embodiment, and for example, the inner surface of each casing is large enough to arrange the entire display unit. If so, the width and thickness in the longitudinal direction and the transverse direction are not particularly limited.

  In the above-described embodiment, the mobile phone 100 has been described as an example. However, the present invention is not limited to the above-described embodiment, and for example, any of a speaker, a microphone, a communication unit, and an operation unit For example, it can be used in portable display devices such as portable televisions, portable car navigation devices, electronic dictionaries, and portable game machines.

  Needless to say, elements may be added or changed as appropriate without departing from the spirit of the present invention.
