By such a connecting mechanism of the lower housing 2 and the upper housing 3 by the pair of slider guides 32, the lower side of the main display 22 of the upper housing 3 is along the front surface 11 (keypad 12) of the lower housing 2. Can move.

  Next, the mounting structure of the lift guide 41 will be described. FIG. 4 is a rear view of the mobile phone 1 for explaining the mounting structure of the lift guide 41. As shown in FIG. 4, a concave portion 27 is formed from the upper portion of the back surface 26 of the upper housing 3 to the central portion, and a pair of holes 28 are formed on both sides of the central portion of the concave portion 27. The lift guide 41 is a long plate-like member, and rotating pins 43 extend from both sides of one end side 42 thereof, and each rotating pin 43 is rotatably fitted in each hole 28.

  A recess 30 is formed above the keypad 12 on the front surface 11 of the lower housing 2, and a pair of holes 29 are formed on both sides of the central portion of the recess 30. Rotating pins 45 extend from both sides of the other end side 44 of the lift guide 41, and each rotating pin 45 is rotatably fitted in each hole 29.

  The length between the rotation centers of both end portions 42 and 44 of the lift guide 41 is sufficiently longer than the length between the slide portion 33 and the rotation portion 34.

  Next, the operation of the opening / closing mechanism between the lower housing 2 and the upper housing 3 by the slider guide 32 and the lift guide 41 as described above will be described with reference to FIGS.

  FIGS. 5 and 6A to 6E are side views of the mobile phone 1. FIGS. 5 and 6 (a) to 6 (e) show the operation of the mobile phone 1 when the slide portion 33 is brought closer to the rotation pin 45 (in the direction of arrow L). The mobile phone 1 can tilt the upper housing 3 with respect to the lower housing 2 depending on the position of the slide portion 33.

  As is clear from FIG. 5, FIG. 5 (a) shows the state of FIG. 1 (a) in which the cellular phone 1 is completely closed, and the upper housing 3 has the front surface 21 (main display 22 side) up. The lift guide 41 is housed in the recesses 27 and 30 in a state where it is completely overlapped on the front surface 11 (on the keypad 12) of the lower housing 2.

  Then, as the slide portion 33 is moved closer to the rotation pin 45, the slide portion 33, the rotation is calculated from the sum of the length between the rotation pins 43, 45 and the length between the rotation portion 34 and the rotation pin 43. The space between the pins 45 is narrowed, and the lift guide 41 gradually raises the main display 22 side of the upper housing 3 with respect to the lower housing 2 with the rotation pin 35 as the rotation center. The state of FIG. 6C shows a state in which the upper housing 3 is raised most.

  When the slide portion 33 is further moved closer to the rotation pin 45 side, the main display 22 side of the upper housing 3 is lowered from the state shown in FIG. 6C (FIG. 6D). Falls completely and the lower housing 2 and the upper housing 3 are completely opened (FIG. 6E). In this state, the back surface of the upper housing 3 is completely in contact with the front surface 11 of the lower housing 2, and the lift guide 41 is stored in the recesses 27 and 30.

  When the mobile phone 1 is placed on a table or the like and a plurality of people watch TV on the main display 22, the mobile phone 1 may be opened in a state as shown in FIG. In this case, in the above-described conventional clamshell type mobile phone, when it is opened in the state shown in FIG. 8B, the connection portion 105 at one upper end of the keypad 102 of the lower housing 101 is used. Since the entire upper housing 103 is supported, it is unstable when it is placed on a table or the like as it is, and there is a risk of falling down due to some inclination or vibration.

  On the other hand, in the mobile phone 1 according to the present embodiment, the upper housing 3 is supported by the lower housing 2 by the slide portion 33 and the rotating portion 34 even when the mobile phone 1 is opened in such a state. That is, it is supported at two points in the length direction of the lower housing 2 (one end portion and an intermediate portion in the length direction), and one point at the end portion in the length direction as in a clamshell type mobile phone. Only the lower housing 101 does not support the upper housing 103.

  At this time, since the amount of movement of the center of gravity by opening the mobile phone 1 can be reduced as compared with the conventional clamshell type and slide type, it is opened in a state as shown in FIG. Even if placed as it is, the mobile phone 1 is stable and does not easily fall down.

  Further, as is apparent from FIGS. 5 and 6, when the cellular phone 1 of the present embodiment is completely closed (FIG. 5A), the lower casing 2 and the upper casing 3 are the same as those described above. The positional relationship is the same as that of the slide type mobile phone (FIG. 8A). Also, in the fully opened state (FIG. 6E), the lower housing 2 and the upper housing 3 are in the same positional relationship (FIG. 8B) as the conventional slide type mobile phone described above, You can make a phone call.

  However, as the upper housing 3 is opened from the state shown in FIG. 5A, the above-described movements shown in FIGS. 5 and 6A to 6E are not present in the conventional mobile phone. In addition, it is possible to provide a mobile phone having a novel opening / closing mechanism other than the clamshell type or the slide type.

  Incidentally, the guide rail 31 and the slider guide 32 may be provided on the outer surfaces of the lower housing 2 and the upper housing 3, for example, on both sides. However, in the present embodiment, since these are housed in the lower housing 2 and the upper housing 3, there is an object between the slider guide 32 and the lower housing 2 and the upper housing 3 due to the movement of the slider guide 32. There is no such thing as getting caught.

  Further, since the guide rail 31 and the slider guide 32 are not exposed outside the casing, it can be said that the appearance of the mobile phone 1 is clean and aesthetically pleasing.

  Furthermore, since the slider guide 32 is housed in the recesses 27 and 30, the back surface of the upper housing 3 completely overlaps the front surface 11 of the lower housing 2 in the state shown in FIGS. 5 (a) and 6 (e). The open state and the closed state similar to the slide type can be realized. Therefore, in the closed state of FIG. 5A, the mobile phone 1 can be stored compactly.

  As shown in FIG. 3, a stopper 36 made of an elastic member that abuts against the slide portion 33 and elastically presses the slide portion 33 in the guide rail 31, for example, in the rail direction 1 or a plurality of locations on the bottom surface thereof. It may be provided. In the present embodiment, a plurality of stoppers 36 are formed by bending a long plate-like plate spring 37 at a plurality of locations in the length direction.

  By providing the stopper 36 in this manner, when the slide portion 33 is positioned on the stopper 36, the slider guide 32 (lower casing 2) becomes heavy and the lower casing 2 can be lightly fixed and supported at the position. it can. And when the slide part 33 gets over the position of the stopper 36, a motion will become light again, and the user can get a click feeling and can know the stop position of the lower housing | casing 2 tactilely.

  As specific mounting positions of the stopper 36, a completely closed position (FIG. 5A), a fully opened position (FIG. 6E), and a position where the upper housing 3 rises highest (see FIG. It can be considered to be provided at three places in FIG.

  As shown in FIG. 1C, a speaker 51 for guidance voice that emits a ringtone, an operation sound, etc. of the mobile phone 1 is provided in the recess 30 of the lower housing 2.

  That is, the mobile phone 1 includes a keypad 12, a main display 22, a receiving speaker 23, a transmitting microphone 13, a connector (not shown), an infrared communication element, a camera lens, a sub display, and the like in a small surface area. is doing. The keypad 12, the main display 22, the reception speaker 23, the transmission microphone 13, and the like are not provided in the recess 30 because the slider guide 32 is obstructive. Even if the slider guide 32 gets in the way, it can be provided in the recess 30 because there is no problem in use.

  Therefore, by providing the speaker 51 in the recess 30 where the keypad 12, the main display 22, the receiving speaker 23, the transmitting microphone 13 and the like cannot be provided, the narrow surface area of the mobile phone 1 can be effectively utilized, A member can be arranged effectively.

  FIG. 7 is a conceptual diagram illustrating electrical connection of the mobile phone 1. As shown in FIG. 7, in addition to the keypad 12, various electronic components such as a main board 61 and a battery 62 are housed in the lower housing 2, and the main display 22 is also disposed in the upper housing 3. In addition, various electronic components such as the sub-board 63 are accommodated. And the electronic component in the lower housing | casing 2 and the electronic component in the upper housing | casing 3 must be connected by wiring.

  Therefore, in this embodiment, the main board 61 and the sub board 63 are connected by using the flexible printed wiring board 64 as a wiring. However, as shown in FIG. The lift guide 41 is inserted between the body 2 and the body 2.

  Such wiring can be inserted through the slider guide 32. However, since the slider guide 32 moves in the lower housing 2, the wiring in the lower housing 2 needs to be longer than necessary. And since this wiring moves in the lower housing | casing 2, if the movement space is not ensured, wiring itself will be easy to hurt. Therefore, it is desirable to store the wiring in the lift guide 41 between the upper housing 3 and the lower housing 2 in terms of protecting the wiring itself and effectively using the space in the lower housing 2.

  In addition, although the example which applied the portable information terminal device of this invention to the mobile telephone 1 was demonstrated so far, the portable information terminal device of this invention is not limited to application to a mobile phone, PHS, PDA, etc. The present invention can be applied to various types of portable information terminal devices.
