[Embodiment 1]
An embodiment of the present invention will be described with reference to the drawings.

  The portable terminal with a projector function (this terminal) of this embodiment is a portable terminal that is easy to carry and can use the projector function while being held in the hand. As this portable terminal, for example, a cellular phone can be used.

  As shown in FIG. 2, the terminal is a folding (clamshell) portable terminal, and includes an upper cabinet (first casing) 1, a lower cabinet (second casing) 2, a hinge unit 3, A display unit (sub display unit) 4 and a projector unit (projector) 5 are provided.

  The upper cabinet 1 is a plate-like body (a rectangular parallelepiped) like the lower cabinet 2 and has a role as a housing for various members together with the lower cabinet 2. The upper cabinet 1 has a display unit (display unit) 4 on both sides or one side, while the lower cabinet 2 has an operation button group (not shown). In addition, although the upper cabinet 1 of this Embodiment is the structure which provided the display part 4 on both surfaces, about another display part (main display part), it is not illustrated.

  The hinge part 3 connects the upper cabinet 1 and the lower cabinet 2 so as to be rotatable (foldable) with respect to each other. The display unit 4 has a role of displaying various images. The upper cabinet 1, the lower cabinet 2, the hinge unit 3, and the display unit 4 have the same configuration as a conventional general mobile phone, and can be appropriately replaced with a mobile phone having another conventional configuration.

  Here, it should be particularly noted that a folding (clamshell) portable terminal is provided with a projector function. More specifically, the projector unit 5 is provided at one end of the upper cabinet 1, that is, at the end of the projector unit 5 opposite to the hinge unit 3 (fixed). The projector unit 5 includes a lens and a light source.

  Thus, by providing the projector unit 5 at one end of the upper cabinet 1 of the terminal, the terminal can be held in a hand like a flashlight in the open state as shown in FIGS. You can project images on the screen.

  Further, the projector function can be used while copying the same image as the image projected by the projector unit 5 to the main display unit and viewing the image of the main display unit. For this reason, fine adjustment of the image projected by the projector unit 5 can be achieved by the operation button group arranged in the lower cabinet 2. Furthermore, by providing the projector unit 5 in the foldable terminal, it is possible to provide a foldable portable terminal with a projector function that has not existed before.

  Further, in the above terminal, as shown in FIG. 1, the direction of the lower cabinet 2 held (gripped) in the hand (direction to be projected; the longitudinal direction of the lower cabinet 2; the direction of arrow A; from the tip of the second casing) The projector unit 5 so that the direction (in the direction along the second housing toward the hinge unit) and the direction actually projected by the projector unit 5 (the direction of arrow B) coincide with each other (so as to be parallel). However, it is preferable that the upper cabinet 1 is disposed obliquely.

  Here, the arrangement of the projector unit 5 is slanted. However, if the projection direction by the projector unit 5 can be changed, it is not always necessary to change the arrangement position of the projector unit 5 itself. In addition, although the direction of the arrow A and the direction of the arrow B coincide with each other, the direction actually projected by the projector unit 5 is not limited to the case where they coincide with each other, and the direction of the upper cabinet 1 (hinge unit) From the direction along the first housing from the direction toward the first tip) to the direction of the lower cabinet 2 as long as possible.

  As shown in FIGS. 1 and 3, most portable terminals that are widely used in the world are opened up to 180 degrees so that the distance between the speaker and the ear and the distance between the microphone and the mouth are shortened during a call. It has no structure. Therefore, as shown in FIG. 3, if the projector unit 5 is arranged so that the direction projected by the projector unit 5 coincides with the direction of the upper cabinet 1 (longitudinal direction of the upper cabinet 1), the direction of the lower cabinet 2 (projection is desired). The direction (arrow V direction in FIG. 3) and the direction actually projected by the projector unit 5 (the direction of the upper cabinet 1; the arrow W direction in FIG. 3) do not match.

  On the other hand, if the projector unit 5 is arranged so that the direction of the arrow A and the direction of the arrow B coincide with each other as in this terminal shown in FIG. Can do. That is, since the projection direction of the projector unit 5 is directed not in the direction parallel to the upper cabinet 1 but in the direction parallel to the lower cabinet 2, the direction in which the user intends to project and the actual projection direction match. Can be used without a sense of incongruity.

  Further, the present invention is not limited to the configuration of the terminal shown in FIG. 1 and may have the following configuration. That is, in addition to the configuration of the terminal described above, as shown in FIGS. 4 and 5, the projector cabinet 6 and the angle detection sensor (angle detection means) 7 may be provided in the terminal.

  The projector unit cabinet 6 is provided in the upper cabinet 1. The projector unit 5 is connected to the upper cabinet 1 via the projector unit cabinet 6. The projector unit cabinet 6 adjusts the projection angle of the projector unit 5 (projection direction; the direction of the projector unit 5). In other words, the projector unit cabinet 6 allows the projector unit 5 to rotate with respect to the upper cabinet 1.

  The angle detection sensor 7 is provided in the hinge portion 3 and detects an angle formed by the upper cabinet 1 and the lower cabinet 2. The angle detection sensor 7 electronically controls the projector unit cabinet 6 so that the projection direction projected by the projector unit 5 is parallel to the direction of the lower cabinet 2 according to the detected angle.

  Thereby, irrespective of the magnitude | size of the angle which the upper cabinet 1 and the lower cabinet 2 comprise, the direction to project can be adjusted. That is, it can always be used in the projection direction without a sense of incompatibility regardless of the opening / closing angle of the portable terminal. FIG. 5 shows a state in which the projector unit 5 projects an image on the screen with the upper cabinet 1 and the lower cabinet 2 fully opened.

  Here, the angle detection sensor 7 is provided, and the projection direction (projection angle) projected by the projector unit 5 is adjusted by electronically controlling the projector unit cabinet 6. However, the present invention is not limited to the angle detection sensor 7, and for example, the projection angle of the projector unit 5 is adjusted by interlocking the projector unit cabinet 6 with the hinge unit 3 by a mechanism such as a gear between the hinge unit 3 and the projector unit cabinet 6. Also good. Further, the projector unit cabinet 6 may be used alone.

  Also, the case has been described in which each of the above terminals is projected in an appropriate direction (direction to be projected) when the projector function is used by holding (grabbing) it in the hand. Next, a description will be given of a portable terminal that can not only use the projector function by hand but also can appropriately project an image even when placed on a desk or the like.

  That is, in addition to the configuration of the terminal described above, as shown in FIGS. 6 and 7, the lower cabinet 2 is provided with a contact sensor (state detection means) 8 and the upper cabinet 1 is provided with a lens shift function (not shown). Also good. The contact sensor 8 is provided at a position where the hand touches when using the projector function with a hand, and detects whether the hand is touching (whether it is in a gripped state) and shifts the lens. It has a role of outputting a detection signal to the function. The lens shift function has a function of shifting the lens up and down based on an output signal from the contact sensor 8.

  43 (a) and 43 (b) are enlarged cross-sectional views showing the periphery of the projector unit 5 shown in FIG. 43A shows the projector unit 5 and the projection direction when the portable terminal is used on a desk or the like, and FIG. 43B shows the case when the portable terminal is used with the hand held. The projector unit 5 and the projection direction are shown. As shown in FIG. 43A, when the portable terminal is used on a desk or the like, the direction of the projector unit 5 and the projector unit cabinet 6 coincides with the direction of the upper cabinet 1 (direction to be projected; X direction). It is supposed to be. Thereby, it can project upwards. On the other hand, as shown in FIG. 43 (b), when the portable terminal is used in the hand, the projector unit 5 and the projector unit cabinet 6 rotate in the Y direction from the state shown in FIG. 43 (a). The direction of the projector unit 5 and the projector unit cabinet 6 is made to coincide with the direction of the lower cabinet 2 (direction to be projected; Z direction). Thereby, the lower cabinet 2 can be projected in the direction.

  The operation of the portable terminal will be described. First, the contact sensor 8 detects whether or not a hand is touching the lower cabinet 2. As shown in FIG. 6, when the hand is touching (grasping), the lens shift function matches the light source and the center of the lens constituting the projector unit 5 (the light source and the center of the lens are aligned). Shift the lens so that they face each other. Thereby, when using it with a portable terminal, the direction actually projected and the direction (direction to project) of the lower cabinet 2 can be made to correspond.

  On the other hand, as shown in FIG. 7, when the mobile terminal is placed on the desk 13 or the like and is not touched, the lens shift function controls the center position of the lens to shift above the light source. When the lens is shifted upward with respect to the light source, as shown in FIG. 7, the range in which the image is projected (projection range) is shifted upward. Therefore, even when the portable terminal is placed at a relatively low position such as the desk 13, the video can be projected in an appropriate direction.

  Here, although the lens is shifted using the lens shift function, the light source may be shifted instead of the lens (the light source shift function may be used). That is, when the hand is touching the mobile terminal, the light source constituting the projector unit 5 is matched with the center of the lens by the light source shift function, while when the hand is not touching the mobile terminal, the light source shift function May shift the light source below the center of the lens.

  Further, the projector cabinet 6 and the angle detection sensor 7 may be used instead of the lens shift function (or the light source shift function). However, when the projector unit 5 is used while being placed on the desk 13 or the like, the projector unit 5 is projected upward, and thus trapezoidal distortion occurs. In order to prevent this trapezoidal distortion, the trapezoidal distortion correction function may be controlled according to the output signal of the contact sensor 8 described above.

  Furthermore, in the above description, the contact sensor 8 is used to detect whether or not the hand is touching the mobile terminal. However, an acceleration sensor (not shown) may be provided instead of the contact sensor 8. Since the acceleration sensor can detect vibration, it can be determined whether or not it is held by hand. Moreover, you may control the position of a lens or a light source using the sensor which detects whether it is contacting the desk 13 etc. instead of the said contact sensor 8.

  Moreover, the following portable terminals may be used. That is, the portable terminal has an upper cabinet 1, a lower cabinet 2, a hinge unit 3, a main display unit 50, a sub display unit 4, and a projector unit 5, as shown in FIGS. 8 (a) and 9 (a). is doing. Further, when the portable terminal is opened, the lower cabinet 2 is used by hand as shown in FIG. 8A. On the other hand, when the portable terminal is closed, FIG. 9A is used. As shown in FIG. 2, the upper cabinet 1 and the lower cabinet 2 are used by grasping them by hand. Further, in the mobile terminal shown in FIG. 8A, the direction to be projected (the direction of the lower cabinet 2) coincides with the projected direction, and the direction in which the mobile terminal shown in FIG. And the projected direction coincide with each other. In the portable terminal shown in FIG. 9A, the direction to be projected, the direction to be projected, the direction of the upper cabinet 1, and the direction of the lower cabinet 2 all match.

  8B is an enlarged cross-sectional view of the projector unit 5 shown in FIG. 8A, while FIG. 9B is an enlarged cross-sectional view of the projector unit 5 shown in FIG. 9A. . As shown in these drawings (FIGS. 8B and 9B), the projector unit 5 includes two optical systems 60 and 61 having different projection directions, an optical system switching mechanism (not shown), and an open / close state. It has a sensor (not shown). The optical system 60 has a light source 51 and a lens 52, while the optical system 61 has a light source 53 and a lens 54. The optical system switching mechanism can switch the projection direction (that is, the optical systems 60 and 61 to be used) depending on whether the portable terminal is closed or open. The open / close sensor has a function of detecting whether the portable terminal is closed or open. For example, a contact sensor provided at a contact portion between the upper cabinet 1 and the lower cabinet 2 or an angle provided at the hinge portion 3. It can be realized by a detection sensor or the like.

  The optical system 60 is disposed obliquely with respect to the upper cabinet 1. More specifically, when the portable terminal is opened and the projector function is used, the projection direction (the linear direction connecting the light source 51 and the lens 52 in the optical system 60) is the direction to be projected (the direction of the lower cabinet 2). To match.

  On the other hand, the optical system 61 is arranged in a direction along the upper cabinet 1. When the portable terminal is closed and the projector function is used, the projection direction (straight direction connecting the light source 53 and the lens 54) coincides with the direction to be projected (the direction of the lower cabinet 2 and the upper cabinet 1). Yes.

  With the above configuration, the open / close sensor detects whether the mobile terminal is closed or open, and the optical system 60 or 61 is selected based on the detection result, so that the mobile terminal is open or In any state in which the portable terminal is closed, the projection direction and the direction to be projected can be matched.

  Here, a portable terminal that can use the projector function in both the opened state and the closed state using the two optical systems 60 and 61 and the optical system switching mechanism together with the open / close sensor is shown. However, the present invention is not limited to this, and the two optical systems 60 and 61 and the optical system switching mechanism are combined with the above-described contact sensor, acceleration sensor, etc., and are either held in a hand or placed on a desk. In this case, a portable terminal that can use the projector function may be used.

  Next, a portable terminal (gear-equipped portable terminal) provided with the above-described gear mechanism will be described. FIG. 10 is a plan view transparently showing a state in which the geared mobile terminal is opened.

  As shown in the drawing, the mobile terminal with gear includes an upper cabinet 1, a lower cabinet 2, a hinge portion 3, a first gear 63, a second gear 64, a third gear 65, a fourth gear 66, 1 shaft 70, second shaft 71, third shaft 72, projector section cabinet 67, and projector section 5. For convenience of explanation, the main display unit 50 and the sub display unit 4 are not shown.

  The first shaft 70 is fixed to the lower cabinet 2 and has a role of fixing the first gear 63, that is, the first gear 63 is also fixed to the lower cabinet 2. If the first gear 63 is fixed by being embedded in the lower cabinet 2, the first shaft 70 is not necessarily required.

  Specifically, the first shaft 70 is disposed perpendicular to the upper cabinet 1 and the lower cabinet 2 and along the direction in which the hinge portion 3 extends. The first gear 63 has a hole at its center, and the first shaft 70 is passed through the hole.

  The second shaft 71 has a role of supporting the second gear 64 and the third gear 65, and is located on the upper cabinet 1 in the direction of the upper cabinet 1 (direction orthogonal to the first shaft 70). Along with the upper cabinet 1, it is rotatably arranged. The second gear 64 is fixed to the end of the second shaft 71 and is rotatable integrally with the second shaft 71. Further, the second gear 64 meshes with the first gear 63 fixed to the lower cabinet 2, and rotates in conjunction with opening and closing of the geared mobile terminal. The second shaft 71 is rotated in conjunction with the rotation of the second gear 64.

  The third gear 65 is provided at the end of the second shaft 71 opposite to the end where the second gear 64 is provided, and in conjunction with the rotation of the second shaft 71, It is being fixed to the 2nd shaft 71 so that it may rotate.

  The third shaft 72 has a role of supporting the fourth gear 66 and is fixed to the projector section cabinet 67 and the projector section 5 that are provided to be rotatable with respect to the upper cabinet 1. That is, the third shaft 72, the projector unit cabinet 67, and the projector unit 5 can rotate together independently of the upper cabinet 1. The third shaft 72 is disposed in parallel with the first shaft 70.

  The fourth gear 66 is fixed to the end portion of the third shaft 72 and is rotatable integrally with the third shaft 72. Further, the fourth gear 66 meshes with the third gear 65 and rotates in conjunction with the third gear 65.

  Next, operation | movement of this portable terminal with a gear is demonstrated using FIG.10 and FIG.11 (a) (b).

  When the geared mobile terminal is shifted slightly from the open state shown in FIG. 11 (a) to the closed state shown in FIG. 11 (b), the second gear 64 rotates in the G direction shown in FIG. Accordingly, the third gear 65 connected to the second gear 64 via the second shaft 71 also rotates in the G direction. When the third gear 65 rotates in the G direction, the fourth gear 66 engaged with the third gear 65 rotates in the H direction. When the fourth gear 66 rotates, the projector unit 5 connected to the fourth gear 66 via the third shaft 72 rotates, so that the projection direction and the projection direction always coincide with each other. ing.

  FIG. 12 is a side view showing a state where the geared mobile terminal is shifted from the opened state to the closed state. As shown in the figure, when the geared mobile terminal is closed, the projector unit 5 can be stored in the geared mobile terminal facing inside. More specifically, from 180 degrees (open state) to 0 degrees (closed state), by rotating the projector unit cabinet 67 and the projector unit 5 while matching the projection direction and the projection direction, In the state, the projector unit 5 can be stored facing the inside of the mobile terminal with gear.

  Further, when the opening / closing angle of the geared mobile terminal is less than 90 degrees (the closed state is 0 degrees and the opened state is 180 degrees), it is determined that the projector unit 5 is not in use and the projection is stopped. The application related to the unit 5 may be stopped.

  Moreover, as shown in FIG. 13, you may provide a cam mechanism (not shown) in said portable terminal with a gear. This cam mechanism has a role of switching the rotation direction of the projector unit 5 between an opening / closing angle of up to 90 degrees and after 90 degrees. The specific operation of the geared mobile terminal equipped with this cam mechanism is such that the projection direction (K direction in the figure) and the direction to project (the direction of the lower cabinet 2) coincide with each other until the opening / closing angle is 90 degrees. The projector unit 5 is rotated in the I direction, and the projector unit 5 is rotated in the J direction opposite to the I direction when the opening / closing angle is 90 degrees or more. Thereby, the projector unit 5 can perform projection even in the closed state. However, in the case of a portable terminal that can be used in an open state or a closed state, the projector unit 5 is turned upside down between the open state and the closed state. It is necessary to reverse it.

[Embodiment 2]
In the above-described embodiment, the portable terminal provided with one rotating hinge (one-axis rotating hinge; hinge portion 3) has been described. However, the present invention is not limited to this, and a swivel type mobile terminal (swivel mobile terminal) having two rotary hinges (biaxial rotary hinges) may be used. The swivel portable terminal is a portable terminal that can reverse the surface on which the main display unit 50 is provided and the surface on which the sub display unit 4 is provided by fixing the lower cabinet 2 and rotating the upper cabinet 1. .

  As shown in FIGS. 14 and 15, the swivel portable terminal includes an upper cabinet 1, a lower cabinet 2, a hinge unit 3, a hinge unit 3 ′, a main display unit 50, a sub display unit 4, a projector unit 5, and a projector unit.

More specifically, this figure shows the projector unit shown in FIG. 15 when it is changed from the open state to the closed state using the hinge unit 3 (that is, the main display unit 50 is in contact with the lower cabinet 2). 5 and the projector section cabinet 6 are shown. FIG. 17 is a cross-sectional view of the swivel portable terminal showing a state in which the projector function is used when the projector is closed. As shown in FIG. 17, the projection direction matches the projection direction even when closed. For this reason, the top and bottom (upper and lower) of the projected image is reversed between when it is opened and when it is closed. When closed as shown in FIG. 17, the projection 75 of the projector cabinet 6 shown in FIG. 16 is pushed by the lower cabinet 2, and the projector cabinet 6 and the projector 5 rotate in the L direction, and the main display unit The projector unit 5 and the lower cabinet 2 are parallel to each other in a state where the 50 and the lower cabinet 2 are in contact with each other.

  FIG. 18 is an enlarged cross-sectional view of the vicinity of the projector unit 5 of the swivel portable terminal. More specifically, FIG. 15 shows that the hinge portion 3 3 ′ is closed from the opened state shown in FIG. 15 (ie, the sub display portion 4 is in contact with the lower cabinet 2). The operation of the projector unit 5 and the projector unit cabinet 6 is shown. And FIG. 19 is sectional drawing of the swivel portable terminal which shows the state which is using the projector function when closed.

  As shown in FIG. 19, the projection direction matches the projection direction even when closed. Therefore, the top (top and bottom) of the projected image is the same when opened and when closed. When closed as shown in FIG. 19, the projection 76 of the projector cabinet 6 shown in FIG. 18 is pushed by the lower cabinet 2, and the projector cabinet 6 and the projector 5 rotate in the N direction, and the sub display unit The projector unit 5 and the lower cabinet 2 are arranged in parallel with each other in a state where 4 and the lower cabinet 2 are in contact with each other. By using such a swivel portable terminal, when the projector function is used in a state as shown in FIG. 19, the main display unit 50 can confirm the image projected by the projector or use various applications relating to the projector. Can be.

[Embodiment 3]
In addition, although the present invention has been described with reference to a foldable portable terminal, the present invention is not limited thereto, and may be a slide-type portable terminal as shown in FIGS. 20 and 21A and 21B. As shown in FIG. 8, the slide type mobile terminal includes an upper cabinet (third housing) 41, a lower cabinet (fourth housing) 42, a display unit 4, and a projector unit 5.

  In this slide type mobile terminal, the joint surface M between the upper cabinet 41 and the lower cabinet 42 is not a straight line but is curved. Specifically, the upper cabinet 41 is gradually thinner as it goes in the direction in which the projector unit 5 is arranged, while the lower cabinet 42 is gradually thicker in the direction in which the projector unit 5 is arranged. Yes.

  Then, the upper cabinet 41 and the lower cabinet 42 are slid along the joint surface M to switch between the slide closed state (see FIG. 21A) and the slide open state (see FIG. 21B). Is possible. This slide type mobile terminal is also provided with the projector unit 5 tilted with respect to the upper cabinet 41 in the same manner as the above terminal. Specifically, in the slide open state, the direction of the lower cabinet 42 (arrow C direction; direction to be projected; direction along the fourth housing in the slide direction) and the direction projected by the projector unit 5 (arrows) (D direction; projected direction) coincides with each other.

  Although not shown, the above-mentioned projector cabinet 6 may also be provided in this slide type portable terminal. When the projector unit cabinet 6 is provided in a slide type portable terminal, it is preferable to provide a slide amount detection sensor (not shown) instead of the angle detection sensor 7 described above. The projector unit cabinet 6 is preferably electronically controlled so that the projection direction projected by the projector unit 5 is parallel to the direction of the lower cabinet 42 in accordance with the slide amount detected by the slide amount detection sensor. Thereby, irrespective of the magnitude | size of the slide amount of the upper cabinet 41 and the lower cabinet 42, the direction to project and the direction to project can be made to correspond.

  Further, although not shown, the slide type mobile terminal may be provided with the contact sensor 8 and the lens shift function (or light source shift function). Further, an acceleration sensor may be provided instead of the contact sensor 8, or a sensor (not shown) for detecting whether or not the desk 13 is touched may be provided.

  Also, a slide type portable terminal that uses a projector function in a state where it is placed on a desk or the like as shown below may be used. That is, FIG. 22 is a perspective view showing a slide type mobile terminal.

  This slide type mobile terminal has an upper cabinet 1, a lower cabinet 2, a main display unit 50, a projector unit 5, and a projector unit cabinet 80.

  FIG. 23 is a perspective view showing the lower cabinet 2 of the slide type mobile terminal. As shown in the figure, the lower cabinet 2 has a notch 81 that is inclined at the end. In FIG. 22, the projector cabinet 80 enters the cutout 81. However, as shown in FIG. 24, the projector section cabinet 80 may not enter the cutout section 81, and a gap 82 may be provided between the lower cabinet 2 and the projector section cabinet 80.

  FIG. 25A is a cross-sectional view showing a state where the slide type mobile terminal is closed (a state where the slide type mobile terminal is not slid). As shown in the figure, the projector section cabinet 80 is in pressure contact with the cutout section 81 of the lower cabinet 2. More specifically, the projector unit cabinet 80 has a rotation shaft 83, and the notch portion 81 of the lower cabinet 2 is pushed by a force to rotate about the rotation shaft 83 in the O direction. The projector cabinet 80 includes a spring (not shown) and the like, and the spring rotates about the rotation shaft 83 in the O direction.

  Therefore, when this portable terminal is slid, as shown in FIG. 25 (b), the projector cabinet 80 rotates in the O direction around the rotation shaft 83, and the projector unit 5 faces upward to change the projection direction. It can be directed obliquely upward, and the projection direction can be changed smoothly. In addition, since the projector unit cabinet 80 is pressed against the notch 81 of the lower cabinet 2, there is no gap between the projector unit cabinet 80 and the lower cabinet 2, and the appearance can be improved.

  Moreover, the following slide type portable terminals may be used. FIG. 26 is a cross-sectional view showing a portable terminal of a type that can be used both when used by being placed on a desk or the like by using a lens shift function.

  As shown in FIG. 26, the slide type portable terminal includes an upper cabinet 1, a lower cabinet 2, a main display unit 50, a projector unit 5, a lens push-up unit (see FIGS. 27A and 27B) 86, and A lens push-up groove 87 is provided. Then, as shown in FIGS. 27A and 27B, the projector unit 5 includes a lens 88 and a light source 89. In addition, the slide-type mobile terminal illustrated in FIG. 26 is in a closed state.

  The lens pushing-up groove 87 is provided in the lower cabinet 2, and the depth of the groove becomes deeper as the end of the lower cabinet 2 is approached, as shown in FIGS. 27 (a) and 27 (b). Yes. However, not only the lens pushing-up groove 87 as described above, but also a notch may be provided at the end of the lower cabinet 2 as shown in FIGS. 25 (a) and 25 (b).

  FIG. 27A is a cross-sectional view showing the closed state of the slide type mobile terminal, and FIG. 27B is a cross-sectional view showing the open state.

  As shown in these drawings, the light source 89 is fixed to the upper cabinet 1, and the lens 88 can move integrally with the lens push-up portion 86. When the lens 88 moves relative to the light source 89, the lens can be shifted and the projection direction can be switched. Specifically, the lens push-up portion 86 is lowered by a certain amount when no force is applied from below (opened state), and the projection direction can be lowered (FIG. 27A). On the other hand, in a state where the force from the bottom is applied (closed state), it is raised by a certain amount, and the projection direction can be raised (see FIG. 27B).

  28 (a) and 28 (b) are cross-sectional views showing the projector unit 5 and its surroundings in FIGS. 27 (a) and 27 (b) in greater detail. Again, as shown in FIG. 28A, when the slide-type portable terminal is closed, the lens 88 is shifted upward with respect to the light source 89, and the image is projected (projection range). Spreads upward. This makes it possible to match the projection direction with the projection direction when used on a desk or the like. On the other hand, as shown in FIG. 28B, when the slide type portable terminal is slid, the lens moves in the P direction (downward), and the center of the light source 89 and the center of the lens 88 coincide with each other. The projection direction matches the direction of the lower cabinet 2. Thereby, the projection direction and the direction to project can be made to correspond.

  Furthermore, as shown in FIGS. 29A to 29C, the tip of the lens push-up portion 86 may be cut obliquely instead of providing the lens push-up portion groove. Specifically, as shown in these drawings, the lens push-up portion 86 is cut so as to increase in length as it approaches the tip of the upper cabinet 1. FIG. 29A shows a state in which the slide type mobile terminal is closed, and FIG. 29B shows a state in which the upper cabinet 1 and the lower cabinet 2 are relatively slid, FIG. 29 (c) is a schematic view showing a state in which it is completely slid. With this configuration, when the upper cabinet 1 and the lower cabinet 2 are relatively slid from the closed state of the slide type mobile terminal, the lens push-up portion 86 moves in the P direction (downward), Even in the closed state and the slid state, the projection direction and the projection direction can be matched.

  Moreover, the following slide type portable terminals may be used. This slide-type portable terminal is configured to rotate the projector unit 5 with a gear. FIG. 30 is a plan view transparently showing the upper cabinet 1 in this slide type mobile terminal. As shown in the figure, the upper cabinet 1 includes a rubber roller 90, a fourth shaft 91, a fifth shaft 92, a sixth shaft 93, a fifth gear 94, a sixth gear 95, and a seventh gear 96. , An eighth gear 97, a projector unit cabinet 98, and the projector unit 5.

  FIG. 31A is a cross-sectional view showing a state in which the slide type mobile terminal is closed, and FIG. 31B is a cross-sectional view showing a state in which the slide type mobile terminal is slid.

  The rubber roller 90 is formed integrally with the fifth gear 94, and rotates on the lower cabinet 2 when the portable terminal is slid. The fourth shaft 91 is connected to the fifth gear 94, and supports the rotation of the fifth gear. The sixth gear 95 meshes with the fifth gear 94 and can rotate together with the fifth gear 94. The seventh gear 96 is connected to the sixth gear 95 via the fifth shaft 92 and rotates in conjunction with the rotation of the sixth gear 95. The eighth gear 97 meshes with the seventh gear 96 and can rotate together with the seventh gear 96. The sixth shaft 93 is connected to the eighth gear 97 and rotates together with the eighth gear. The projector section cabinet 98 is rotated by the rotation of the sixth shaft 93 and has a role of rotating the projector section 5. In the drawing, reference numerals R, S, T, and U denote a fifth gear 94, a sixth gear 95, and a seventh gear 96, respectively, when shifting the mobile terminal from the closed state to the slid state. And the rotation direction of the eighth gear 97 is shown.

  According to the above configuration, in the closed state, the projection direction can be matched with the direction to be projected when held in the hand like a flashlight, while in the slid state, it is placed on a desk or the like. Sometimes the projection direction can coincide with the direction to be projected.

[Embodiment 4]
Another embodiment of the present invention will be described with reference to the drawings.

  In the first embodiment, the folding type or sliding type portable terminal has been described. However, as in this embodiment, a straight-type mobile terminal (straight terminal) including a single housing that does not have a folded portion or a slide portion may be used. In this embodiment, in order to explain the difference from the first embodiment, for the sake of convenience of explanation, members having the same functions as those described in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Is omitted.

  As shown in FIG. 32, the straight terminal includes a cabinet (fifth housing) 10, a button group 11, a display unit 4, a projector unit 5, and a housing support unit 12.

  The cabinet 10 is a plate-like body (cuboid) and plays a role as a housing for various members. The button group 11 has a role of switching an image on the display unit 4 and switching various functions such as a projector function or a call function.

  In particular, as shown in FIG. 33, the housing support portion 12 has a role of lifting one end of the cabinet 10 (the end where the projector unit 5 is provided) when placed on a desk 13 or the like. In general, when the projector function is used on a desk 13 or the like, it is often projected to a position higher than the position where the projector is placed. According to the above configuration, when the straight terminal is placed on the desk 13 or the like, the projected direction can be set to a position higher than the placement position of the straight terminal, as shown in FIG. Therefore, it is possible to match the direction of projection with the direction of projection. Furthermore, the housing support part 12 shown in FIG. 33 has a contact sensor 100 at its tip. The contact sensor 100 has a function of detecting whether or not it is in contact with a desk or the like, and correcting a trapezoid when detecting contact with a desk or the like.

  Moreover, since the housing support portion 12 is provided at one end of the cabinet 10, it should not be disturbed when the straight terminal is held in the hand, and should be held in the hand and used as shown in FIG. You can also. When the straight terminal is held straight, the direction of the cabinet 10 and the direction projected by the projector unit 5 coincide with each other as shown in FIG.

  In addition to the configuration of the straight terminal, a projector unit cabinet 15 may be provided in the cabinet 10 as shown in FIG. This projector unit cabinet 15 has a built-in projector unit 5 and can be rotated 360 degrees in the direction of arrow E. The projector unit 5 is projected to the outside of the cabinet 10 (see FIG. 36B), The projector unit 5 can be switched between a storage state (see FIG. 36A) in which the projector unit 5 faces the inside of the cabinet 10. That is, the projector unit cabinet 15 can rotate the projector unit 5.

  Further, as shown in FIG. 36 (a), the portable terminal determines that the projector function is not used in the housed state, and the projector function is stopped.

  In addition, the portable terminal has a structure in which the housing support portion 12 automatically protrudes when the portable terminal is rotated in the arrow F direction from the above-described storage state to the projection state shown in FIG. In this case, a sensor for detecting the rotation of the projector unit 5 may be provided, and the housing support unit 12 may come out by a driving device (not shown) in accordance with an output signal of the sensor. Moreover, the structure which the housing | casing support part 12 protrudes in response to rotation of the projector part 5 may be sufficient.

  Further, the above-described straight terminal is provided with the housing support portion 12, but this housing support portion 12 is not necessarily an essential configuration. Instead of the case support unit 12 in the straight terminal, a direction switching unit 19 that switches the direction of the projector unit 5 may be provided as shown in FIGS.

  The direction switching unit 19 is composed of a spring, a mainspring, or the like, and can switch the projection direction of the projector unit 5 when it is held in a hand or placed on a desk 13 or the like. Inside the direction switching unit 19, the projector unit 5 is provided, and the projector unit 5 is driven in conjunction with the operation of the direction switching unit 19.

  Specifically, when no external force is applied to the direction switching unit 19 (when the portable terminal is held in the hand), the projection direction is the direction of the cabinet 10 (the length of the cabinet 10) as shown in FIG. Direction). In this case, the direction switching part 19 has a part (protrusion part 33) protruding downward. That is, as shown in FIG. 38, the direction switching unit 19 is in a state where the lower end (projection portion 33) is obliquely lowered.

  On the other hand, as shown in FIG. 39, when the mobile terminal is placed on the desk 13 or the like, the protrusion 33 is pushed up by the reaction force from the desk 13. Therefore, the direction switching unit 19 is straightened, and the projector unit 5 is also pushed up in conjunction with the operation of the direction switching unit 19 so that the projection direction is directed upward as compared with the case where it is held in the hand. That is, by driving the projector unit 5 by the operation of the direction switching unit 19, it is possible to match the projection direction with the projection direction. Further, in the straight terminal shown in FIG. 39, the projector unit cabinet 15 is provided with a rotation angle detection means, and an output signal of the rotation angle detection means detects that the portable terminal is placed on a desk or the like. In this case, keystone correction is performed.

  Further, in the straight terminal described above, the housing support portion 12 is provided, but instead of the housing support portion 12, a rod-shaped lens push-up portion 25 may be provided as shown in FIG. This straight terminal includes a lens 26 and a light source 27 as shown in FIG. The lens push-up portion 25 extends downward from the lower end portion of the lens 26 and protrudes from the cabinet 10. The lens pusher 25 is movable up and down, and the lens 26 can be pushed up by a force from below. That is, the lens push-up portion 25 has the lens shift function described above.

  When the portable terminal having the lens push-up portion 25 is used by being held in hand, the lens push-up portion 25 is not added from below as shown in FIG. At this time, the light source 27 and the center of the lens 26 coincide with each other (the light source 27 and the center of the lens 26 face each other). For this reason, the direction of the housing (the direction in which the image is desired to be projected) matches the actually projected direction.

  On the other hand, when the portable terminal having the lens push-up part 25 is used on the desk 13 or the like, the lens push-up part 25 is pushed up by the reaction force from the desk 13 as shown in FIG. Shifts up. For this reason, the projection range actually projected moves upward. Therefore, the projection range actually projected can be brought close to the projection range to be projected. Although the lens 26 is shifted here, the light source 27 may be shifted.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims, and embodiments obtained by appropriately combining technical means disclosed in different embodiments. Is also included in the technical scope of the present invention.

  The portable terminal with a projector function of the present invention can be suitably used particularly for a cellular phone equipped with a projector.
