Description

  The present invention relates to a mobile phone, and more particularly to a slide-type mobile phone in which casings stacked in a stacked manner slide relative to each other.

  In recent years, mobile phones have been increasingly demanded to be thin and small. At the same time, in order to improve operability, it is also required to provide a display with a large area and an operation unit. In response to such demands, in recent years, a slide-type mobile phone having a structure in which two casings such as a casing on the display side and a casing on the operation key unit side slide relative to each other from a stacked state has been used.

On the other hand, if the mobile phone is further reduced in thickness, if an antenna is provided on the back side of the operation key unit side housing, a sufficient distance between the antenna element and the slide mechanism unit, which is a metal body, should be secured. Therefore, it has been difficult to ensure radiation efficiency. At the same time, as the distance between the antenna element and the human body becomes closer due to the reduction in thickness, the SAR (specific absorption rate) has also increased, and Japan standards (2.0
There was a problem that it was difficult to satisfy (10 g average).

  As a method for solving the above problem, there is also used a method in which a part of a housing is formed by projecting and an antenna is placed in the projecting part regardless of slide deployment / storage. However, in such a method, when the slide is stored, the protruding portion remains protruding from the housing, and it is difficult to store the mobile phone, for example, when the user catches the mobile phone in a pocket or bag. was there. Further, depending on the position where the antenna portion is formed, there is a problem that a user operating the mobile phone may cover the antenna with his hand, and in such a case, radiation efficiency may deteriorate.

  In recent years, curved slide type mobile phones have been introduced. The curved slide type is a structure in which the casing slides in a curved shape, whereby the operation key side casing and the display unit side casing are positioned at an appropriate angle when the slide is expanded. In this way, the user gets a natural feeling of operation, and the housing that slides and expands to the shape of the side of the face fits when making a call, so the receiver and ear, microphone and mouth are brought closer to each other more naturally. be able to. As a result, a call can be made without feeling stress, and operability can be improved.

  However, in the case of a curved slide type mobile phone as well as the above-described normal slide type terminal, when a reduction in thickness is pursued, the problem that the antenna radiation efficiency is lowered due to the influence of the slide mechanism part may occur in the same manner. Moreover, the solution has only the method of protruding an antenna part like the said slide type terminal. Further, in the SAR measurement, as described above, since the housing and the face side of the pseudo human body are fitted, the antenna element is closer to the face surface of the human body, so the SAR is larger than that of the normal slide type terminal. There is a tendency to end up.

JP 2004-328346 A

  Here, Patent Document 1 discloses a configuration for improving antenna radiation efficiency or SAR in a foldable mobile phone in which two housings are opened and closed. In this document, in conjunction with the opening / closing operation of the mobile phone, the tip of the antenna is configured to start away from the base of the mobile phone, that is, the back of the housing, starting from the base end.

  However, since the configuration disclosed in Patent Document 1 is configured to be applicable to a foldable mobile phone, such a structure cannot be applied to the above-described slide-type mobile phone. There has been a problem that communication quality cannot be improved while achieving reduction in thickness and thickness. Further, in the above document, the antenna tip always protrudes from the main body, and is intended for a rod-shaped antenna that is configured to be extended and used in use, so that the structure for separating the long antenna portion from the main body becomes complicated and large. There was a problem.

  For this reason, the present invention improves the above inconveniences. In particular, in a slide type mobile phone, the antenna structure can be reduced without protruding from the casing when the slide is housed, and the slide structure can be sufficiently thinned while being thinned. An object of the present invention is to provide a mobile phone capable of obtaining high radiation efficiency.

  Therefore, in the slide type mobile phone of the present invention, a pair of housings arranged in a stacked manner, a slide mechanism provided between the pair of housings to open and close each other, and a communication radio wave And an antenna unit that performs transmission and reception, and when the pair of housings are opened by sliding, an antenna moving means is provided to move the antenna unit away from the slide mechanism.

  According to the present invention configured as described above, when the housing is slid and opened by the slide type mobile phone, the antenna unit is moved away from the slide mechanism. Therefore, since the distance between the antenna unit and the slide mechanism formed of a metal body is increased, the radiation efficiency of the antenna can be improved and the communication quality can be improved. Have

  The present invention is characterized in that, in a slide type mobile phone terminal, antenna radiation efficiency at the time of slide deployment can be ensured with a simple configuration, and at the same time, SAR (specific absorption rate) can be improved. Further, when the present invention is applied to a curved slide type terminal, the angle of the optical axis of the camera and the display surface of the display device can be kept vertical during camera shooting regardless of whether the slide is unfolded or stored.

  A slide-type mobile phone according to an aspect of the present invention includes a pair of casings arranged in a stacked manner, a slide mechanism that is provided between the pair of casings, and opens and closes the pair. And an antenna unit that transmits and receives radio waves for communication, and includes an antenna movable unit that moves the antenna unit away from the slide mechanism when the pair of housings are opened by sliding. The configuration is taken.

  According to the above invention, when the housing is slid and opened by the slide type mobile phone, the antenna unit is moved away from the slide mechanism. Therefore, when the casing is slid and opened during a call or the like, the distance between the antenna portion and the slide mechanism formed of a metal body is increased, so that the radiation efficiency of the antenna can be improved. As a result, communication quality can be improved.

  Further, in the present invention, the antenna moving means is configured to move so that the antenna portion is separated from the formation surface of the speaker that outputs the reception sound and the microphone that inputs the transmission sound provided in the pair of housings. take. Thus, when the user slides and opens the mobile phone to make a call, the antenna unit is separated from the speaker and microphone formation surface of the housing. Therefore, the antenna unit can be separated from the head of the user who makes a call with the mobile phone placed on the head, and the SAR (specific absorption rate) can be reduced.

  Moreover, in this invention, the structure which provided the antenna part in the surface on the opposite side to the formation surface of the speaker and microphone of a housing | casing is taken. Furthermore, the present invention employs a configuration in which the antenna portion is provided at the end of the housing where the housings overlap each other when the pair of housings are opened by sliding.

  As a result, since the antenna portion is provided on the surface opposite to the speaker and microphone forming surface where the human head is closer to the housing, the speaker, microphone, and slide mechanism are more Can be separated. In particular, when it is slid and opened, the antenna part is provided on the opposite side of the end of the casing located near the center and where the casings overlap. The part will be located. Therefore, communication quality can be further improved and SAR can be reduced.

  Also, in the present invention, the antenna moving means is predetermined by a sliding operation of the other casing with respect to a member interlocked with the antenna portion provided in one casing when the pair of casings are opened by sliding. The antenna part is moved by energizing the force of the above. Specifically, the antenna movable means is equipped with an antenna portion, engages with one housing, and is movable with respect to the one housing, and the other housing is provided in the other housing. And a movable force urging portion that urges a force that moves the movable portion when the slide is opened. More specifically, the movable portion includes a protrusion that protrudes toward the slide surface of the other housing, and the movable force biasing portion is formed on the slide surface of the other housing, and protrudes from the movable portion. And a groove portion that urges a force to move the movable portion by pressing the protruding portion when the other housing is slid and opened.

  Thus, when the casing is slid, a member that interlocks with the antenna section, for example, a movable force biasing section provided on the other casing that slides on the protruding section formed on the movable section equipped with the antenna section. The antenna portion can be moved by pressing at the groove portion and energizing a predetermined force. In this way, it can be realized with a simple configuration, and manufacturing can be facilitated and costs can be reduced.

  Further, in the present invention, the slide mechanism is a mechanism that slides the pair of casings in a curved manner, and includes a speaker that outputs a reception sound and a microphone that inputs a transmission sound provided in the pair of casings. A configuration in which a camera unit is provided on a housing surface opposite to the forming surface, and a camera moving unit that moves the camera unit so that the shooting direction of the camera unit changes when the pair of housings are opened by sliding is configured. take. The camera moving means adopts a configuration in which the camera unit is moved so that the optical axis representing the shooting direction by the camera unit is perpendicular to the display surface of the display unit provided in the housing. Furthermore, in this invention, the structure of equip | installing a camera part in the movable part equipped with the said antenna part is taken.

  For this reason, for example, in the case of a curved slide type terminal, because of a pair of casings that are curved and slid, the optical axis of the display unit and the camera does not become a right angle when it is slid and opened, and natural shooting is not possible. However, since the optical axis of the camera unit and the display surface of the display unit are positioned at a right angle even when it is slid and opened, natural and simple shooting is possible.

  A first embodiment of the present invention will be described with reference to FIGS. 1 to 5 and FIGS. 10 to 13. FIG. 1 is a diagram showing an external appearance of a slide type mobile phone according to the present embodiment, and shows a state when the slide is developed. FIG. 2 is a side sectional view of the mobile phone, and FIG. 3 is a side sectional view when the mobile phone is slid and developed. 4 to 5 are diagrams showing the configuration of each housing. 10 to 13 are diagrams showing a basic configuration of the mobile phone.

And as shown in FIG. 1, a pair of housing | casing 10 and 20 is comprised by the upper side housing | casing 10 in which the display part 11 was provided, and the lower side housing | casing 20 in which the operation part 21 was provided, It is comprised so that it can slide mutually along the long side direction of each housing | casing 10 and 20 (refer arrow A). For example, when an operation such as a call is performed, the slide is unfolded (slide open (state shown in FIG. 1)), and when not used or only the display screen is viewed, the slide is stored (slide and close). The slide type mobile phone 1 according to the present invention is not limited to the configuration and shape shown in FIG. For example, a part of an operation unit having a cross key, a determination key, or the like may be formed below the display unit 11 of the upper housing 10.

  Here, the basic configuration of the slide type mobile phone will be described with reference to FIGS. FIG. 10 shows a side cross-sectional view when the slide type mobile phone 201 is slid and housed, and FIG. 11 shows a side cross-sectional view when the slide type mobile phone 201 is slid and deployed. First, the upper housing 210 includes a substrate 212 therein, and includes a display unit 211 that is installed on the substrate 212 and positioned on the surface of the upper housing 210 (the right side surface in FIG. 10). In addition, an upper slide mechanism 213 that engages with the lower housing 220 and can be opened and closed is provided on the back surface (the left surface in FIG. 10) of the upper housing 210 that is the opposite surface. . FIG. 12A shows a view of the upper housing 210 in which the upper slide mechanism 213 is formed as viewed from the back side. FIG. 12B is a cross-sectional view taken along line EE in FIG.

  As shown in FIG. 12, the upper slide mechanism 213 is formed of a thin plate-like metal plate having a predetermined thickness provided on substantially the entire back surface of the upper housing 210. It is formed in a substantially rectangular shape that is slightly smaller than the rectangular back surface. Two concave rail grooves 213a having a predetermined depth are formed in the vicinity of each long side along the long side direction. In addition, in the lower end portion of the upper casing 210, that is, in FIG. 11, each race is positioned on the operation section 221 side of the lower casing 220 when it is slid and unfolded. The groove 213a ends and a rail end is formed.

  The lower housing 220 includes a substrate 222 therein, and includes an operation unit 221 that is installed on the substrate 222 and located on the surface of the lower housing 220 (the right side surface in FIG. 10). Further, a battery 224 is provided on the back surface (the left surface in FIG. 10) of the lower housing 220 which is the opposite surface. Furthermore, a lower slide mechanism 223 that engages with the above-described upper housing 210 and can be opened and closed is provided on the surface of the substrate 222.

FIG. 13B shows a cross-sectional view taken along line FF in FIG.

  As shown in FIG. 13, the lower slide mechanism 223 is disposed above the back side of the lower housing 220 and is formed of a thin metal plate having a predetermined thickness. The lower slide mechanism 223 is formed in a substantially rectangular shape having a short side on the long side of the lower housing 220 that is substantially rectangular, and extends along the short side (the long side of the housing 220). Thus, two convex guides 223a having a predetermined height are formed near each short side. The guides 223a are respectively fitted into the rail grooves 213a formed in the upper slide mechanism 213, and the guides 223a slide in the rail grooves 213a, so that the pair of housings 210 and 220 slide. It becomes possible, and deployment and storage are realized. The rail groove 213a terminates at the lower end side, and the guide 223a abuts against the rail end, so that the sliding operation stops in the state of being slid and unfolded as shown in FIG. The position at the time of 220 slide development is determined. Note that by adjusting the length of the guide 223a and the length of the rail groove 213a, the positional relationship between the upper casing 210 and the lower casing 220 during deployment and storage can be set.

  Note that the upper slide mechanism 213 and the lower slide mechanism 223 are applied with a strong force when the cellular phone 201 is dropped or the like, so that it is necessary to ensure the strength, and metal is desirable. In particular, since it is a place exposed to the outside air, it is preferable that it is formed using SUS304 which is resistant to corrosion among metals. However, this is an example, and the slide mechanisms 213 and 223 may be formed of any material.

  In addition, on the back side of the lower housing 220, as shown in FIG. 11, in the vicinity of the center when the slide is unfolded and in a portion overlapping the upper housing 210, transmission / reception of communication radio waves is performed. An antenna unit 240 is provided for performing the above. In other words, the antenna unit 240 is provided on the upper end side opposite to the lower end side provided with the battery 224 that is slid and held by the user. A camera unit 250 for acquiring images is also provided on the back side of the lower housing 220.

  The mobile phone 1 according to the present embodiment is configured based on the configuration described with reference to FIGS. 10 to 13 described above. The configuration of the mobile phone 1 in the present embodiment will be described with reference to FIGS.

The pair of housings 10 and 20 are provided with the upper housing 10 (the other housing) provided with the display unit 11 and the speaker 16 for outputting the reception sound on the surface, and the operation unit 21 and the transmission sound on the surface. It is comprised by the lower housing | casing 20 (one housing | casing) in which the microphone 26 was provided.

  2 shows a side sectional view when the slide type mobile phone 1 is slid and housed, and FIG. 3 shows a side sectional view when the slide type mobile phone 1 is slid and developed. First, similarly to the above, the upper housing 10 is equipped with a substrate 11 and includes a display unit 11 that is installed on the substrate 11 and is located on the surface of the upper housing 10 (the right side surface in FIG. 2). Yes. In addition, an upper slide mechanism 13 that engages with the lower housing 20 and can be opened and closed is provided on the back surface (the left surface in FIG. 2) of the upper housing 10 that is the opposite surface. . FIG. 4A shows a view of the upper housing 10 in which the upper slide mechanism 13 is formed as seen from the back side. Moreover, the sectional view on the AA line of Fig.4 (a) is shown in FIG.4 (b).

  As shown in FIG. 4, the upper slide mechanism 13 is formed of a thin plate-like metal plate having a predetermined thickness provided on substantially the entire back surface of the upper housing 10. It is formed in a substantially rectangular shape that is slightly smaller than the rectangular back surface. Two concave rail grooves 13a having a predetermined depth are formed in the vicinity of each long side along the long side direction. It should be noted that each lower end of the upper housing 10, that is, an end portion that is located on the operation unit 21 side of the lower housing 20 and is below the display unit 11 when being slid and deployed as shown in FIG. The race groove 13a is terminated and a rail end is formed. Further, the upper slide mechanism 13 in this embodiment is formed deeper than the rail groove 13a on the center line along the longitudinal direction and from the upper end to a position slightly below the center in the longitudinal direction. A concave antenna movable groove 13b (movable force biasing portion (groove portion)) is formed. As will be described later, the antenna movable groove 13b is fitted with a protrusion 23b of the movable part 30 provided with the antenna part 40, and further, the antenna movable groove 13b is in contact with the movable part 30 when the slide is unfolded. The movable force will be energized.

  In addition, the lower housing 20 includes a substrate 22 therein, and includes an operation unit 21 that is installed on the substrate 22 and is located on the surface of the lower housing 20 (the right surface in FIG. 2). Further, a battery 24 is provided on the back surface (the left surface in FIG. 2) of the lower housing 20 which is the opposite surface. In the same manner as described above, a lower slide mechanism 23 that engages with the above-described upper housing 10 and allows opening and closing is provided on the surface side of the substrate 22. FIG. 5A shows a view of the lower housing 20 in which the lower slide mechanism 23 is formed as viewed from the front surface side. FIG. 5B is a sectional view taken along line BB in FIG.

  As shown in FIG. 5, the lower slide mechanism 23 is disposed above the back side of the lower housing 20 and is formed of a thin metal plate having a predetermined thickness. The lower slide mechanism 23 is formed in a substantially rectangular shape having a short side on the long side of the lower casing 20 that is a substantially rectangular shape, and along each short side, Two convex guides 23a having a predetermined height are formed. The guides 23a are respectively fitted in the rail grooves 13a formed in the upper slide mechanism 13, and the guides 23a slide in the rail grooves 13a, whereby the pair of housings 10 and 20 slide. It becomes possible, and deployment and storage are realized.

  Further, in the lower casing 20 in the present embodiment, the upper end portion thereof, that is, the end portion that overlaps the upper casing 10 even when the upper casing 10 is slid out is separated from the operation section 21 side. Thus, the movable part 30 including the antenna part 40 is configured. And this movable part 30 is engaged with the lower housing | casing 20 by the hinge 31 on the back side so that rotation is possible. For example, two hinges 31 are provided, and the movable part 30 side and the casing 20 on the operation part 21 side are in close contact with each other by an appropriate force by elastic parts such as a metal spring and rubber. It is configured to apply a force in the direction. As will be described later, the movable unit 30 rotates about the hinge 31 as a fulcrum when the slide is unfolded, whereby the antenna unit 40 located on the back side further moves to the back side (see FIG. 3).

  Further, on the surface side of the movable portion 30, a protrusion 23 b (protruding portion) that protrudes toward the back surface side of the upper housing 10, that is, the upper slide mechanism 13 is formed. As shown in FIG. 5, the protrusion 23 b is located substantially at the center on the lower housing 20 side of the movable portion 30, and corresponds to the position of the antenna movable groove 13 b formed in the upper slide mechanism 13 described above. is doing. The depth also protrudes by a length that can be accommodated in the antenna movable groove 13b. As shown in FIG. 3, when the upper casing 10 moves upward, the protrusion 23b comes into contact with the rail end, which is the terminal end of the antenna movable groove 13b formed at substantially the center of the upper slide mechanism 13, and moves upward. The force pressed by the is energized. Thereby, the movable part 30 will rotate with the hinge 31 as a fulcrum. Note that a camera unit 50 for image acquisition is also provided on the back surface of the lower housing 20 located below the movable unit 30.

  As described above, the movable portion 30 equipped with the antenna portion 40, the protrusion 23b formed on the movable portion 30, the upper slide mechanism 13 that accommodates the protrusion 23b and serves as a guide and presses the protrusion 23b when the slide is unfolded. As will be described later, the antenna movable groove 13b formed in the above functions as an antenna movable means that can move the antenna portion 40 away from the slide mechanisms 13 and 23. It should be noted that the arrangement of the protrusion 23b and the antenna movable groove 13b, the length and width of the groove 13b, and the strength of the spring of the hinge 31 are such that the antenna portion 40 rotates to an appropriate angle with the hinge 31 as a fulcrum when the slide is deployed. Adjusted.

[Operation]
Next, the operation of the slide type mobile phone 1 having the above configuration will be described. First, as shown in FIG. 2, the protrusion 23b is accommodated in the antenna movable groove 13b when the upper housing 10 and the lower housing 10 are in the state of being fully stacked. Due to the spring force of the hinge 31, the movable part 30 is urged clockwise with the hinge 31 as a fulcrum. Accordingly, the movable portion 31 is in close contact with the lower housing 20, and the back surface of the movable portion 30 and the back surface of the lower housing 20 are in a straight line to form a flat plane. That is, the antenna unit 40 is flat with respect to the surface of the battery 24.

  Thereafter, as shown by an arrow Y1 in FIG. 3, when the upper casing 10 is slid upward with respect to the lower casing 20, as described above, the guide 23a formed in the lower slide mechanism 23 is moved upward. While moving along the rail groove 13 a formed in the mechanism 13, the protrusion 23 b of the movable portion 30 moves along the antenna movable groove 13 b formed in the upper slide mechanism 13. When the upper housing 10 moves to a position where the upper housing 10 can slide to the maximum extent, the protrusion 23b of the movable portion 30 is formed on the rail end of the antenna movable groove 13b formed at a substantially central position in the longitudinal direction of the upper slide mechanism 13. Abuts and presses the projection 23b upward. Then, since the movable part 30 is pivotally supported on the lower housing 20 by a hinge 31 on the back side, when a pressing force is urged upward on the protrusion 23b, the movable part 30 can move integrally with the protrusion 23b. The portion 30 rotates counterclockwise with the hinge 31 as a fulcrum (see arrow Y2). That is, since the protrusion 23b is integral with the movable part 30 equipped with the antenna part 40, the movable part 30, that is, the antenna part 40 is moved in conjunction with the movement of the protrusion 23b. Then, as shown in FIG. 3, the antenna unit 40 provided on the back side of the movable unit 30 can be further separated from the back surface.

  In particular, the antenna unit 40 can be separated from the metal slide mechanisms 13 and 23 by the above operation, so that it is possible to improve the radiation efficiency during a call. As a result, call quality can be improved. At the same time, the antenna unit 40 located on the back side rather than the surface on which the speakers and microphones are formed is further separated from the front side, so that the distance of the antenna unit 40 from the human head can be further increased during a call. SAR (specific absorption rate) can also be reduced. At this time, in particular, the movable unit 30 that moves the antenna unit 40 is provided at the upper end of the lower housing 20, so that the antenna unit 40 can be prevented from being gripped by the user during a call and from the head. Since the position is further away, the SAR can be lowered while further improving the communication quality. And as above-mentioned, since it can implement | achieve with a simple structure, manufacture can be facilitated and cost reduction can be achieved.

  Next, a second embodiment of the present invention will be described with reference to FIGS. In the mobile phone 101 according to the present embodiment, first, as described above, a pair of substantially rectangular casings 110 and 120 having a predetermined thickness are engaged so as to be slidable with respect to each other. In particular, as will be described later, the pair of housings 110 and 120 are formed so that the slide surfaces of the slide mechanism are curved. When the slides are slid to each other and are slid and deployed, they form a predetermined angle with each other. Thus, it is configured to have a “ku” shape.

It is formed in a substantially rectangular shape that is slightly smaller than the rectangular back surface. Two concave rail grooves 113a having a predetermined depth are formed in the vicinity of each long side along the long side direction. Each race groove 113a is positioned on the lower end of the upper casing 110, that is, on the operation section 121 side of the lower casing 120 when being slid and deployed as shown in FIG. On the end side, the groove is terminated and a rail end is formed. Further, the upper slide mechanism 113 in the present embodiment has a concave antenna movable groove formed on the center line in the longitudinal direction and deeper than the rail groove 113a from the upper end to the center portion in the longitudinal direction. 113b (movable force biasing portion (groove portion)) is formed. As will be described later, one end of an insulator 125 that interlocks with the movable portion 130 provided with the antenna portion 140 is fitted into the antenna movable groove 13b. Further, the antenna movable groove 113b is interposed via the insulator 125. Thus, a movable force is applied to the movable portion 130.

  In addition, the lower housing 120 includes a substrate 122 therein, and includes an operation unit 121 that is installed on the substrate 122 and positioned on the surface of the lower housing 120 (the right surface in FIG. 2). Further, a battery 124 is provided on the back surface (the left surface in FIG. 2) of the lower housing 120 which is the opposite surface. In the same manner as described above, a lower slide mechanism 123 that engages with the above-described upper housing 110 and can be opened and closed is provided on the surface side of the substrate 122. FIG. 9A shows a view of the lower casing 120 in which the lower slide mechanism 123 is formed as viewed from the front side. Moreover, the DD sectional view taken on the line of Fig.9 (a) is shown in FIG.9 (b).

  As shown in FIG. 9, the lower slide mechanism 123 is disposed above the back side of the lower housing 120 and is formed of a thin metal plate having a predetermined thickness. The lower slide mechanism 123 is formed in a substantially rectangular shape having a short side on the long side of the lower housing 120 that is a substantially rectangular shape, and near each short side along the short side. Two convex guides 123a having a predetermined height are formed. The guides 123a are fitted into the rail grooves 113a formed in the upper slide mechanism 113, and the guides 123a slide in the rail grooves 113a. It becomes possible, and deployment and storage are realized. Note that the slide surface, which is a contact surface between the upper slide mechanism 113 and the lower slide mechanism 123, is formed in a curved shape by drawing an arc, whereby the slide operation is curved.

  Further, the lower casing 120 in the present embodiment is configured such that the upper end portion thereof, that is, a part of the end portion that overlaps when the upper casing 110 is slid and deployed, is a separate member from the operation unit 121 side. The movable unit 130 including the antenna unit 140 and the camera unit 150 is configured. And this movable part 130 is engaged with the frame part extended from the lower housing | casing 120 with the hinge 131 at both ends of the surface side so that rotation is possible. For example, two hinges 131 are provided, and the back side of the movable part 130 and the surface side of the lower housing 120 are applied with appropriate force by elastic parts such as a metal spring and rubber. It is comprised so that force may be applied to the direction which adjoins. The movable part 130 rotates with the hinge 131 as a fulcrum, so that the antenna part 140 and the camera part 150 located on the back side further move to the back side (see FIG. 7).

  In addition, a substantially L-shaped insulator 125 is pivotally supported at the center of the lower casing 120, and one end of the insulator 125 is on the rear side of the upper casing 110, that is, the upper slide mechanism 113. It becomes the protrusion (protrusion part) which protrudes toward. As shown in FIG. 9, this protrusion is located at substantially the center of the short side of the lower housing 120 and corresponds to the position of the antenna movable groove 113 b formed in the upper slide mechanism 113 described above. . The height also protrudes by a length that can be accommodated in the antenna movable groove 113b. As shown in FIG. 7, when the upper casing 110 moves upward, the protrusion is a rail end that is a terminal end of the antenna movable groove 113b formed in the central portion along the longitudinal direction of the upper slide mechanism 113. Come into contact with each other and are pushed upward to rotate. Then, the other end of the lever 125 presses the claw portion 132 fixedly mounted on the movable portion 130, whereby the movable portion 130 rotates with the hinge 131 as a fulcrum.

  When the slide is unfolded, as shown in FIG. 7, the pair of casings 110 and 120 are curved and slid, so the surfaces of the casings 110 and 120 are positioned at an angle. In conjunction with this, the movable part 130 rotates and the angle of the back surface of the movable part 130 on which the camera unit 150 is mounted also changes. At this time, the movable unit 130 moves so that the optical axis C, which is the shooting direction of the camera unit 150, is perpendicular to the display surface of the display unit 111 provided in the upper housing 110. In addition, the movable angle of the movable part 130 includes all projections of the insulator 125, the arrangement of the antenna movable groove 113b, the length and width of the groove 113b, and the strength of the spring of the hinge 131. Can be set so that the desired angle, that is, the optical axis C and the display surface of the display unit 111 are at right angles.

  As described above, the movable unit 130 equipped with the antenna unit 140 and the camera unit 150, the insulator 125 that moves the movable unit 130, and the projection that is one end of the insulator 125 are accommodated to serve as a guide for the housing. The antenna moving groove 113b formed in the upper slide mechanism 113 that slides and presses the movable portion 130 when the slide is unfolded is an antenna moving means for moving the antenna portion 140 and a camera moving means for moving the camera portion 150 as well. Is functioning as

[Operation]
Next, the operation of the slide type mobile phone configured as described above will be described. First, as illustrated in FIG. 6, when the upper housing 110 and the lower housing 120 are fully stacked, the protrusion of the insulator 125 is housed in the antenna movable groove 113b. . Further, the movable portion 130 is biased by the spring force of the hinge 131 so as to rotate counterclockwise with the hinge 131 as a fulcrum. Therefore, the back surface of the movable part 130 and the back surface of the lower housing 120 are in a straight line to form a flat plane. That is, the antenna unit 140 and the camera unit 150 are flat with the surface of the battery 124. As a result, the optical axis C of the camera unit 150 and the surface of the display unit 111 are at right angles.

  Thereafter, as shown by an arrow Y11 in FIG. 7, when the upper casing 110 is slid upward with respect to the lower casing 120, the guide 123a formed on the lower slide mechanism 123 is moved upward as described above. The protrusion of the insulator 125 moves along the rail groove 113b formed in the upper slide mechanism 113 along the rail groove 113a formed in the mechanism 113. Since the slide surfaces of the slide mechanisms 113 and 123 are formed to be curved, the upper casing 110 also moves in a curved manner with respect to the lower casing 120 and has a predetermined angle with each other. It becomes the character shape.

  When the upper housing 110 moves to a position where it can be slid to the maximum, the protrusion of the insulator 125 comes into contact with the rail end of the antenna movable groove 113b formed at substantially the center position in the longitudinal direction of the upper slide mechanism 113. The projection is pressed in the slide development direction, that is, upward in FIG. Then, as shown by an arrow Y12 in FIG. 7, the insulator 125 rotates counterclockwise, and the end opposite to the protrusion presses the claw 132 provided on the movable portion 130 toward the back side. . Thereby, the movable part 130 will rotate with respect to the lower housing | casing 120 by using the hinge 131 as a fulcrum (refer arrow Y13). That is, the antenna unit 140 provided on the back side of the movable unit 130 can be further separated from the back surface. At the same time, the camera unit 150 provided on the back side of the movable unit 130 is also separated from the back side, and the angle of the optical axis C changes. However, as described above, the display surface of the display unit 111 of the upper housing 110 is caused by the curved slide. The angle is also changed, and the movable state is set so that the angle of the optical axis C of the camera unit 150 also changes corresponding to the change. Specifically, the movable unit 130 is set to move so that the optical axis C that is the shooting direction of the camera unit 150 is perpendicular to the display surface of the display unit 111 provided in the upper housing 110. Yes.

  As described above, because of the pair of cases 110 and 120 that are curved and slid, the inconvenience that the optical axes of the display unit 111 and the camera unit 150 do not become a right angle when slid and opened may occur. As a result, even when sliding open, the optical axis C of the camera unit 150 and the display surface of the display unit 111 are positioned at a right angle. Therefore, natural and easy shooting is possible.

  Similarly to the above, since the antenna unit 140 can be separated from the metal slide mechanisms 113 and 123, the radiation efficiency during a call can be improved. At the same time, the antenna unit 140 located on the back side rather than the surface on which the speakers and microphones are formed is further separated from the surface side, so that the distance of the antenna unit 140 from the human head can be further increased during a call. SAR (specific absorption rate) can also be reduced. And since this structure is realizable with a simple structure, manufacture can be facilitated and cost reduction can be achieved.

  Further, as in the first and second embodiments described above, the part equipped with the antenna unit 140 and / or the camera unit 150 that is a part of the casing is moved in conjunction with the sliding operation, so that the irregular operation is performed. Can be enjoyed and the design can be improved.
