Description

  The present invention relates to a portable information terminal device that can display an image captured by an imaging lens on a display and freely perform fast-forwarding of a reproduced image by an operation ring such as a shuttle ring.

  Conventionally, as a mobile phone with a camera as an example of a portable information terminal device provided with a camera function, a substantially rectangular display portion provided with an imaging lens and a display is provided with a substantially rectangular shape provided with a numeric keypad. Some are attached to the main body so that the angle and direction can be adjusted by a right-angle biaxial joint. (For example, Reference 1)

However, in this type of conventional mobile phone with camera, since the imaging lens and the display are attached to the same display, the rectangular image of the display is maintained while keeping the rectangular angle of view of the imaging lens sideways. You cannot shoot with the corners held sideways.
In addition, this type of conventional camera-equipped cellular phone is not provided with a shuttle ring or the like for fast-forwarding a reproduced image.

Further, as shown in FIG. 3, a power button 44, a connector socket 45, and a strap mounting portion 46 are mounted on one side surface 2 c of the main body 2. Also, a charging connector insertion socket 47 is mounted on the lower end 2e of the main body 2, and a plurality of VHG lamps 48 are mounted on the corner portions of the back surface 2b and the side surface 2c of the main body 2.
A flash 49 is mounted on the upper end of the front surface of the lens barrel 3, and a photographing confirmation lamp 50 is mounted on one side of the upper end side of the front surface 2 a of the main body 2.

Here, a method of using the portable information terminal device 1 based on the above-described embodiment will be described.
(1) First, as shown in FIGS. 1 and 2, the display support unit 6 and the display unit 8 of the portable information terminal device 1 are folded to the folding position of the back surface 2 b of the main body 2. As shown in FIG. 2, with the display support unit 6 and the display unit 8 facing the upper side of the main body 2, the user gently grips the front 2 a side of the main body 2 with the right hand.
(2) Next, lightly place the right thumb on the side surface 6d of the display support 6 and lightly push the display support 6 in the direction of the arrow b with the right thumb.
Then, the display support unit 6 and the display unit 8 are integrally rotated in the direction of arrow b against the spring force of the reversing spring mechanism of the automatic reversing mechanism 15, and the display supporting unit 6 and the display unit 8 are shown in FIG. At the moment when the intermediate position P13 is overcome in the direction of arrow b, the display support portion 6 and the display portion 8 are automatically pulled out in the direction of arrow b to the pulling position P12 shown in FIG. It is.

(3) Therefore, as shown in FIGS. 4 and 5, the display unit 8 is picked up and down with the left hand, and the display unit 8 is rotated 180 ° in the direction of the arrow c around the rotation fulcrum 7 shown in FIG. The display 9 of the display unit 8 is turned rearward.
(4) After that, the display button 37 of the display unit 8 is pressed with the left hand, the display 9 is turned on, the top of the photo and movie is performed by the mode button 32 with the thumb of the right hand, and the cross keys 24, 25, 26 with the thumb of the right hand. And 27 are appropriately pressed to appropriately perform spot focus, strobe setting, macro setting, timer setting, etc., and then press the decision key 28 with the right thumb to determine the setting state.
(5) Further, with the right thumb, the non-slip uneven surface 22 and the anti-slip rib 23 on the outer periphery 21a of the shuttle ring 21 are pressed, and the shuttle ring 21 is moved within a certain angle (θ11 + θ12) from the midpoint P0. After rotating and adjusting in the directions of arrows e and f to adjust exposure at the time of shooting, the photo button 30 or the movie button 31 is pressed with the thumb of the right hand to shoot a still image or a moving image.
At this time, in order to correct the change in the angle of the display 9 associated with the angle of the imaging lens 4 with respect to the subject, the display unit 8 is moved around the rotation support 7 with respect to the display support unit 6 in the directions of the arrows c and d with the left hand. The angle is adjusted and the display 9 is corrected so that it faces the photographer's face correctly.
(6) And, at the time of photographing, as shown in FIG. 9, the display 9 is folded on the back surface 2b of the main body 2 together with the display support portion 6 with the display 9 facing the back side. The left and right ends of the type information terminal device 1 are held with both left and right hands, the photo button 38 or the movie button 39 is pushed with the left thumb, and a captured still image or moving image is displayed on the display 9.
At the same time as shooting, the forward rotation of the forward and backward directions of the still image and moving image is performed by rotating the shuttle ring 21 in the direction of the arrows e and f within a certain angle (θ21 + θ22) from the midpoint P20 with the right thumb. It can be performed.

At this time, for example, as shown in FIG. 4, the display unit 8 is integrated with the display support unit 6 and pulled out to the left pulling position P12 of the main body 2 and the display 9 of the display 8 is set in a horizontal state. When the display unit 8 is folded to the folding position P11 on the rear surface of the main body 2 together with the display support unit 6 and the display 9 of the display unit 8 is set in a horizontal state as shown in FIG. When the image is reproduced, the center point P20 with respect to the display 9 which is the phase state of the shuttle ring 21 and the cross keys 24 to 27 with respect to the display 9, and the rotation direction (arrow 21 , F direction) can always be in the same state.
Therefore, in the folded state of FIG. 9, the operation of rotating the shuttle ring 21 in the directions of arrows e and f with the thumb of the right hand etc. to fast-forward the playback image in the forward direction or the reverse direction is the same as when shooting. There is also a feature that can be performed smoothly.

Next, characteristics of the first example of the angle setting of the imaging lens 4 with respect to the main body 2 will be described with reference to FIGS.
At this time, a reference line extending in the up-down direction along substantially the center in the thickness direction of the main body 2 is defined as a first reference line P1, and a reference line having a right angle θ1 with respect to the first reference line P1 is defined as a second reference line. When P2 is set, the optical axis P2 of the imaging lens 4 is set to an elevation angle of a small angle θ2 that increases toward the front of the main body 2 with respect to the second reference line P2.
The angle θ2 of the imaging lens 4 is preferably 4 ° to 10 °, and most preferably 5 ° to 8 °.
In other words, the optical axis P3 of the imaging lens 4 is preferably set to 94 ° to 100 ° with respect to the first reference line 1, and most preferably set to an angle θ3 of 95 ° to 98 °. .
Incidentally, the axis P4 of the turntable 5 substantially coincides with the second reference line P2.

By setting the optical axis P2 of the imaging lens 4 configured as described above, as shown in FIG. 10, the user (photographer) holds the main body 2 of the portable information terminal device 1 with, for example, the right hand, and the imaging lens. When taking a still image or a moving image with the optical axis P2 of 4 facing the subject, the vertical first reference line P1 of the main body 2 has an angle θ4 of, for example, approximately 5 ° with respect to the vertical line PO1. When the camera is set to be tilted forward (tilt forward and downward) by the elevation angle, the optical axis P2 of the imaging lens 4 is set to be almost horizontal, and the screen of the display 9 is tilted upward by, for example, 5 °. Will be.
That is, in general, when shooting a still image or a moving image with the portable information terminal device 1, the photographer slightly tilts the face (head) FS forward (tilt forward or downward), and the portable information It is the most natural and comfortable posture (= setting mode) that the terminal device 1 is slightly tilted forward so as to be substantially parallel to the direction of the face (head).

  On the other hand, compared with the case where the photographer holds the main body 2 of the portable information terminal device 1 with, for example, the right hand and holds it vertically, the screen of the display 9 is very much better when the main body 2 is tilted slightly forward. It becomes easy to see.

However, in this portable information terminal device 1, for example, the main body 2 held by the right hand is naturally aligned with the photographer's face (head) FS slightly tilted forward by an angle θ4 of 5 °, for example (in parallel). When, for example, the optical axis P2 of the imaging lens 4 is set to a substantially horizontal state when it is set in a state slightly tilted forward by 5 °, the screen of the display 9 is, for example, approximately 5 °. It can be set to an upwardly inclined state by the amount.
As a result, the photographer can drop the line of sight P4 onto the screen of the display 9 inclined slightly upward from the rear and from the uppermost position (seeing the screen). Then, while directly looking at the screen of the display 9 from the upper side in the most comfortable posture, the shuttle ring 2, the cross keys 24, 25, 26, 27, the determination key 28, the mode button 32, The photo button 30, the movie button 31, and other operation buttons can be operated. And the characteristic which can image | photograph a still image and a moving image accurately and smoothly with the most comfortable attitude | position is acquired by the imaging lens 4 which the optical axis P2 was set to substantially horizontal shape.

Next, features of the second example of the angle setting of the imaging lens 4 with respect to the main body 2 will be described with reference to FIG.
First, a tripod mounting base 61 formed in a prismatic shape with a lightweight, high-strength member such as an aluminum alloy or engineering plastic is fixed to one side portion inside the lower end 2e of the main body 2 vertically, A screw hole (female screw) 62 for mounting the tripod is formed concentrically at the lower end of the central portion of the tripod mount 61.
As in FIG. 10, in a state where the second reference line P2 is set at a right angle θ1 with respect to the first reference line P1 extending in the vertical direction substantially along the center of the thickness direction of the main body 2, The elevation angle of the small angle θ2 is preferably set to 4 ° to 10 °, most preferably 5 ° to 8 ° so that the optical axis P2 of the imaging lens 4 becomes higher with respect to the second reference line P2. I'm.
In addition, as the vertical axis P5 of the screw hole 62 of the tripod mounting base 61 moves upward with respect to the above-described first reference line P1 on the front of the main body 2, it is rearward (meaning opposite to the front surface 2a side). This is set to an elevation angle of a small angle θ5 that tilts toward the bottom.

If the portable information terminal device 1 has the relationship between the optical axis P3 of the imaging lens 4 set in this way and the axis P5 of the screw hole 61 of the tripod mounting base 61, as shown in FIG. This is very convenient when taking a moving image while setting on a tripod base 63 for a handy type video camera (video movie) and panning with the imaging lens 4.
At this time, the tripod base 63 for a handy type video camera (video movie) or the like has a camera mounting base 66 mounted on the upper part of a fixed base 65 to which a level 64 is attached so that panning / tilting is possible. The camera mounting base 66 is configured to be panned / tilted by a pan / tilt handle 68 having the above. The operation that is frequently used is photographing while rotating a handy type video camera (video movie) horizontally mounted by a mounting screw 69 on a camera mounting base 66 horizontally set by a level 64. Pan operation (horizontal rotation operation).

Therefore, the portable information terminal device 1 is placed by the main body 2 on the camera mounting base 66 set horizontally on the tripod base 63, and the mounting screws 69 are inserted into the screw holes 62 of the tripod mounting base 61 of the main body 2. When fastened from below, the tripod mounting base 61 is set vertically on the camera mounting base 66, and the axis P5 of the screw hole 62 is set vertical, the first reference line P1 of the main body 2 becomes the screw hole. The angle θ2 of the optical axis P3 of the imaging lens 4 is canceled by the forward tilt angle that is tilted forward by a small angle θ5 as it goes upward with respect to the axis P5 of 62, and the optical axis P3 of the imaging lens 4 is almost It will be automatically set to the horizontal state.
Thereby, when panning (horizontal rotation operation) of the imaging lens 4 by the handle 68 is performed, the optical axis P3 of the imaging lens 4 can be panned easily and stably in a horizontal plane, and the generated moving image Panning can be performed easily and stably.

  However, as shown in FIG. 12, the axis P5 of the screw hole 62 of the tripod mount 61 shown in FIG. 11 is placed so as to coincide with the first reference line P1 of the main body 2, and the main body of the portable information terminal device 1 is placed. 2 is mounted on a camera mounting base 66 set horizontally on a tripod base 63 for a handy type video camera (video movie) or the like, and the mounting screw 69 is inserted into the screw hole 62 of the tripod mounting base 61. Fastened from below, the main body 2 is set vertically on the camera mounting base 66, and an elevation angle such as 5 ° is set on the optical axis P3 of the imaging lens 4 so that still images of a distant view can be easily taken. Is possible.

In a state where the battery 73 is slightly depressed in the direction of the arrow g while being slightly depressed in the direction of g, and the battery 73 is slightly depressed in the direction of the arrow g against the pushing spring 77, as shown in FIG. 17 and FIG. By pushing in the direction of arrow n, the locking member 91 is rotated in the direction of arrow n around the pair of left and right fulcrum pins 92 in the direction of the arrow n, and the locking portion 91a of the locking member 91 is moved to the battery. The fingertip is separated from the locking member 91 by being locked at a right angle to the corner portion of the end surface 73 b of 73.
Then, as shown in FIGS. 17 and 19A, the battery 73 is slightly pushed back in the direction of the arrow g by the pushing spring 77, and the end surface 73 b of the battery 73 is engaged with the locking portion 91 a of the locking member 91. The battery 73 is abutted and locked at right angles, and the battery 73 is prevented from falling off from the storage portion 71.

Next, as shown in FIG. 16, the entire opening / closing lid 78 is moved from the open position shown in FIGS. 16 and 17 to the temporarily closed position shown in FIG. , A position where it is closed in a direction perpendicular to the h direction), and pivots in the arrow j direction around the pair of left and right fulcrum pins 82.
Then, at this position, the opening / closing lid 78 is received by the stopper 90 integrally formed on the side surface of the tripod mounting base 61, and the opening / closing lid 76 is set in a state substantially parallel to the end surface 73 b of the battery 73.
Therefore, as shown in FIG. 15, thereafter, as shown in FIGS. 13 and 14, the finger slip prevention portion 80a formed on the outer surface of the slide lid 80 of the open / close lid 78 on the arrow k direction side is applied. When the slide lid 80 is slid in the direction of the arrow k between the unlock position shown in FIG. 16 and the lock position shown in FIG. 15 along the lid support arm portion 77b of the rotating arm 79 so as to press the fingertip. The pair of locking projections 86 and 87 of the slide lid 80 are simultaneously locked to the pair of locking portions 88 and 89 of the main body 2 from the direction of the arrow k. Then, the distal end 81a of the leaf spring 81 of the rotating arm 79 is relatively locked in one positioning recess 84 of the slide lid 80, and the slide lid 80 is clicked locked.
At this time, as shown in FIG. 15, the locking portion 91 a of the locking member 91 is closed together with the locking member receiver 94 by the end 80 b of the slide lid 80 on the arrow k direction side, and the end of the slide lid 80 is closed. The release preventing portion 80c integrally formed inside the vicinity of the portion 80b is brought close to or in contact with the locking portion 91a of the locking member 91 from the direction of the arrow k. Therefore, in the closed / locked state of the opening / closing lid 78, the locking member 91 is inadvertently rotated in the direction of the arrow o from the battery locking position shown in FIG. 15 to the locking release position shown in FIG. There is no inconvenience that rattling occurs in the portion 71 or that the locking at the closed position of the opening / closing lid 80 is released due to the rattling. Therefore, high safety can be obtained.

Thus, the closing operation of the opening / closing lid 78 is completed, and the battery 73 is doubly locked in the storage portion 71 by the locking member 91 and the opening / closing lid 78.
That is, the corner portion of the end surface 73 b of the battery 73 is locked at a right angle by the substantially U-shaped locking member 91, and the slide lid 80 of the opening / closing lid 78 is supported by the pair of locking projections 86 and 87. The pair of locking portions 88 and 89 of the main body 2 are locked from a direction perpendicular to the arrow h direction, which is the direction in which the battery 73 falls off, and are locked by the leaf spring 81. Even if the member 91 is detached from the corner portion of the end face 73b of the battery 73 in the direction of arrow o, and the load of the battery 73 is applied to the opening / closing lid 78 at a right angle from the direction of arrow h, the member 91 can be opened and closed. The slide lid 80 of the lid 78 inadvertently escapes in the direction of the arrow m, and the slide lid 80 does not detach from the pair of locking portions 88 and 89 of the main body 2 in the direction of the arrow m. There can be prevented from being inadvertently released from the main body 2 in the arrow i direction.

Note that when the battery 73 is taken out, an operation opposite to the above-described operation is performed.
That is, the sliding lid 80 of the opening / closing lid 78 is slid in the direction of the arrow m from the locking position shown in FIG. 15 to the unlocking position shown in FIG. Is detached from the pair of locking portions 88 and 89 in the direction of the arrow m. At this time, the distal end 81a of the leaf spring 81 is slid relative to the positioning recesses 84 to 85 in the direction of the arrow k and is click-engaged again in the positioning locking portion 85. Is temporarily fixed at a position slid in the direction of the arrow m with respect to the rotating arm 79.
Next, as shown in FIG. 17, the entire opening / closing lid 78 is opened by rotating it in the direction of the arrow i to the fully open position shown in FIG. 17 around the pair of left and right fulcrum pins 82. As shown in (B), the battery 73 is pushed in the direction of the arrow g slightly against the pushing spring 77 by the fingertip, and the locking member 91 is opened by the other fingertips around the pair of left and right fulcrum pins 92. When the battery 73 is released so as to rotate in the direction of arrow o, the battery 73 is popped up by the push spring 77 in the direction of arrow h upward from the inside of the storage portion 71 as shown by a two-dot chain line in FIG.
Accordingly, after this, the end surface 73b of the battery 73 can be easily extracted from the storage portion 71 by, for example, picking it with a fingertip.
By the way, according to the opening / closing lid device 72, a pair of fulcrum pins are provided on both side surfaces of the lightweight / high rigidity tripod mounting base 61 in which the light / high rigidity rotating arm 79 of the opening / closing lid 78 is fixed in the main body 2. 82, the opening / closing lid 78 and its mounting structure are very strong, and the portable information terminal device 1 may be inadvertently dropped on the floor or the like.
