Action to the portable phone of present embodiment is described below.

At first, at the state of not operation, as Figure 1A, 1B and shown in Figure 2, operating portion 37c is positioned at lower end, and photograph mechanism 20 (optical facilities 30) is positioned at the off-position (indentation state) that the surface by main body 10 is retracted into.At this moment, lobe plate 37 is positioned at the mobile terminal that V is directed downwards as shown in Figure 5.

At this state, when the operator moves to Figure 1A with operating portion 37c, when the position shown in the double dot dash line of 1B (operating portion 37c '), then follow this to move, lobe plate 37 moves to the top of Fig. 5.Thus, the camming action of the pin 33d of the 1st lens mount 33 by the 1st cam path 37a forwards (arrow F direction) move the position of the pin 33d in Fig. 5.Pin 36d in the 2nd lens mount 36 is by the camming action of the 2nd cam path 37b, and forwards (arrow F direction) moves, the position of the pin 36d ' in Fig. 5 (near the bending point of the 2nd cam path 37b).

At this moment, the position (photograph mechanism 20 ') of the optical facilities 30 lens barrel 33a of concavees lens 32 (keep) shown in the double dot dash line among Figure 1B and shown in Figure 3, outstanding slightly by the surface of main body 10, be positioned the camera site of long coke side end.Meanwhile, the part of lobe plate 37 engages with switch, switch connection, and beginning is powered to CCD24.Thus, horse back can (optical facilities 30 CCD24) be taken by photograph mechanism 20.

But, 37c moves if the operator makes operating portion, then in the shot location of above-mentioned long coke side end, detent mechanism (not shown) action, resistance to move operation increases, owing to can not move it with identical operations power, carve at this moment, make optical facilities 30 be positioned the camera site of long coke side end.

In addition, as detent mechanism, such as, can adopt following proposal: groove (groove) is set, on the side of lobe plate 37 by being pressed in the half-circle projection portion of the spring on the outer peripheral face that is pressed against lobe plate 37 at ordinary times in this groove, to realize the location.

When state from the camera site that is positioned at long coke side end, the operator is with the operating physical force of the detent force that can remove detent mechanism, 37c further moves to Figure 1A with operating portion, position shown in the double dot dash line among the 1B (operating portion 37c "); then follow this to move, lobe plate 37 further moves to the top of Fig. 5.Thus, the pin 33d of the 1st lens mount 33 is under the camming action of the 1st cam path 37a, and forwards (arrow F direction) moves, the pin 33d in Fig. 5 " the position.On the other hand, the pin 36d of the 2nd lens mount 36 is under the camming action of the 2nd cam path 37b, and rearward (arrow R direction) moves, the pin 36d in Fig. 5 " the position.

When the state of operator from the camera site that is positioned at long coke side end, the pulling force of the detent force by can removing detent mechanism when antenna 203 further is stretched to position shown in Figure 12 C, then follows this to move, and lobe plate 37 is moved further to the top of Figure 13.Thus, the camming action of the pin 33d of the 1st lens mount 33 by the 1st cam path 37a forwards moves (arrow F direction), arrives the pin 33d among Figure 13 " the position.On the other hand, the camming action of the pin 36d of the 2nd lens mount 36 by the 2nd cam 37b, rearward (direction of arrow R) moves, and arrives the pin 36d among Figure 13 " the position.At this moment, optical facilities 30 (the lens barrel 33a that keeps concavees lens 32) are as Figure 12 C and shown in Figure 4, and are further outstanding from the surface of main body 200, are positioned the camera site of wide-angle side end.

On the other hand, when the operator carries out on the contrary with antenna 203 indentations, and when it is contained in action in the main body 200, then optical facilities 30 arrive the camera site of long coke side end from the camera site of wide-angle side end, at the moment, and the run of lobe plate 37, switch is disconnected, stop power supply, then, arrive the off-position that is in the indentation state to CCD24.

In the above-described embodiments, varifocal optical system is adopted in optical facilities 30, even but be single-focusing optical facilities, by following moving of antenna 203, optical facilities are positioned the camera site, and then the action of the on/off by making switch realizes interlock, can successfully switch to take action.

Have again, in the above-described embodiments, adopted the camming action of lobe plate 37 as the driving mechanism of the enlargement factor that can change optical facilities 30, but be not limited thereto, can adopt other mechanism.

In addition, in the above-described embodiments, provided the flexible operation of following antenna 203, the structure of driving cam plate 37, but also can on lobe plate 37, form tooth bar, to be connected with the motor driver of the pinion wheel of this tooth bar engagement and motor etc., the flexible operation by following antenna 203 can realize electric driving with switch connection/disconnection.

In addition, in the above-described embodiments, provided portable phone as suitable portable information terminal of the present invention, but also be not limited thereto, also applicable to portable personal computer with antenna etc.

As mentioned above, if adopt this portable information terminal, the operator is only by carrying out the expanding-contracting action of antenna 203, just optical facilities 30 can be positioned the camera site, the expanding-contracting action by CCD24 claps just can be positioned the camera site with optical facilities 30, take by CCD24, and then, can carry out from the camera site of long coke side end, arrive the continuous zoom action of the camera site of wide-angle side end.

Therefore, needn't when taking, carry out the beamhouse operation of trouble,, therefore, can make the time lag that reaches in the time of to take minimum, obtain portable phone with convenience owing to, just can be in shooting state at once only by carrying out the operation of pullout antenna 203.In addition,, just between long burnt shooting and wide angle shot, switch serially, therefore, when changing coverage, needn't little by little change shooting distance owing to only suitably adjust the amount of tension of antenna.

Figure 15 A, 15B～Figure 19 A, 19B, 19C represent the another embodiment of portable information terminal of the present invention (being portable phone here).In addition, because photograph mechanism 20 (optical facilities 30) identical with shown in aforesaid Fig. 2～4, so the omission of the explanation here.This portable phone such as Figure 15 A shown in the 15B, comprise the main body 300 that forms outline; Can show with various signals and send the display part (LCD monitor) 301 that receives relevant information; Telescopic antenna 302; Various action buttons 303; But the cover plate 304 of the folding of overlapping operation button 303 grades; Be used for aforesaid photograph mechanism 20 that photographed is taken etc.

Lobe plate 37 is as Figure 16 and shown in Figure 17, constitutes by the flat board of rectangle, and by being formed at the rectangular opening 21a up and down in the

housing

21,21b, (V direction) leads to it with reciprocal move mode along the vertical direction.The side of lobe plate 37 has the 2nd cam path 37b that makes the 1st linearly obliquely cam path 37a and roughly be the く font.As Fig. 16 and shown in Figure 17, one end 341a of the 1st link 341 is connected in the bottom of lobe plate 37 in the mode that can swing, the other end 341b of the 1st link 341 rotatably is connected on the end 342a of the 2nd link 342 shown in Figure 15 B.The other end 342b of the 2nd link 342 such as Figure 15 B and shown in Figure 180 are connected in the mode that can swing on the bolster 315 of cover plate 304.

Between the 2nd link 342 and cover plate 304, as shown in figure 18, be provided with interlock spring 43.The setting of this interlock spring 43 makes and applies bias force at the 2nd link 342 and cover plate 304 when predetermined angular is thrown off.

That is,, then apply bias force so that both are pushed open if cover plate 304 and the 2nd link 342 are approaching with the angle that is narrower than predetermined angular, on the other hand, if cover plate 304 and the 2nd link 342 will leave with the angle greater than predetermined angular, then apply bias force, so that both are furthered.The direction biasing that turns clockwise, the 1st link 341 is drop-down, on the other hand,, make the 2nd link 342 along the biasing of the direction that is rotated counterclockwise among Figure 15 B at the state that cover plate 304 is opened, will lift on the 1st link 341.By above-mentioned the 1st link 341 and the 2nd link 342, interlock spring 343 etc. just forms and the link gear opening action of cover plate 304 and closing motion interlock, that optical facilities 30 are positioned camera site and accommodated position.

As shown in figure 18, on the 2nd link 342, near the 342b of the other end, form concordant 342c.On the other hand, as Figure 15 A and shown in Figure 180, limiting part 344 is being supported on the main body 300 along the mode that the L direction moves back and forth.But limiting part 344 by with concordant 342c bond-off, realize the cam part 344a of camming action and protrude in that the operating portion 344b of operation constitutes manually from the outside of main body 300.

That is, in Figure 18, when limiting part 344 is positioned at the mobile terminal of L1 direction, the pendulum angle minimum of the 2nd link 342, when limiting part 344 is positioned at the mobile terminal of L2 direction, the pendulum angle maximum of the 2nd link 342.

Limiting part 344 can arrive the moment of the camera site of long coke side end from optical facilities 30 by the opening action of cover plate 304, limits the swing of the 2nd link 342.Then, before optical facilities 30 arrive the camera site of wide-angle side end, can be corresponding with this position, limit the pendulum angle of the 2nd link 342 continuously.

Promptly, can be by the opening action of cover plate 304, at first make optical facilities 30 be projected into the camera site of long coke side end, then, by adjusting limiting part 344, regulate the swing position of the 2nd link 342, can be at the coverage from long coke side end to the wide-angle side end, the zoom operation that carries out optical facilities 30.

In addition, be provided with the switch (not shown) that concordant 342c of detection limit parts 344 and the 2nd link 342 contacts, this switch carries out the action to the on/off of the power supply of CCD24 power supply.That is, the cover plate 304 that will be in closed condition is opened, and in concordant 342c of the 2nd link 342 and this switch motion when cam part 344a contacts, beginning is powered to CCD24.

So when limiting part 344 was arranged in the position of L1 direction end of Figure 18, cover plate 304 was opened, be projected into moment of the position of long coke side end in optical facilities 30, CCD24 becomes on-state, can take.In addition, when limiting part 344 was arranged in the position of L2 direction end of Figure 18, cover plate 304 was opened, and optical facilities 30 are projected into the moment of wide-angle side end position, and CCD24 becomes on-state, can take.When the position of limiting part 344 between above-mentioned two positions, in the moment of the zoom position in the middle of optical facilities 30 are positioned at, CCD24 becomes on-state, can take.

Like this,, can take,, can reduce the time lag before taking so can take at once by CCD24 because only by cover plate 304 is opened, switch just moves.

Cover plate 304 shown in the 15B, has half-round 304a as Figure 15 A, and this half-round 304a can be around bolster 315 rotations, and in closing state, it is overlapping operation button 303 not only, but also covers optical facilities 30.Therefore,, cover optical facilities 30, block, in addition, can prevent from concavees lens 32 grades, to adhere to situations such as dust or generation damage so will enter the exterior light of CCD24 by half-round 304a in closing state.

Like this, the parts as with coverage mode protection optical facilities 30 are not provided with independent parts, and adopt the part of cover plate 304 simultaneously, thus, number of components are reduced, and cost reduces.In addition, here, cover plate 304 is made the shape that covers action button 303 and optical facilities 30 degree, still, obviously, also makes the shape of the degree that covers display part 301.

Below according to Fig. 2～Fig. 4, Figure 17, Figure 19 A, 19B, 119C is described the action of the portable phone of present embodiment.

At first, at the state of not operation, shown in Figure 19 A, cover plate 304 is closed, and optical facilities 30 are in the off-position that is retracted into from the surface of main body 300 as shown in Figure 2.At this moment, lobe plate 37 is positioned at the mobile terminal that V is directed downwards as shown in figure 17.In addition, optical facilities 30 are in the state that is covered by cover plate 304.

At this moment, limiting part 344 is positioned at the mobile terminal of L1 direction.In addition, if at this state, shown in Figure 19 B, the operator opens cover plate 304, then follows this to move, and the 2nd link 342 and the 1st link 341 move, lobe plate 37 is moved to the top of Figure 17, the 2nd link 342 contacts with limiting part 344, realizes stopping, and lobe plate 37 also stops.

Thus, the camming action of the pin 33d of the 1st lens mount 33 by the 1st cam path 37a, forwards (arrow F direction) moves, and arrives the pin 33d among Figure 17, the position.On the other hand, the camming action of the pin 36d of the 2nd lens mount 36 by the 2nd cam path 37b, forwards (arrow F direction) moves, and arrives the pin 36d among Figure 17, the position.

At this moment, optical facilities 30 (the 1st lens mount 33) are shown in Fig. 3 and Figure 19 B, and are outstanding slightly from the surface of main body 300, are positioned the camera site of long coke side end.Meanwhile, switch motion, beginning is powered to CCD24.Thus, can take at once.

If the state from the camera site that is in long coke side end makes limiting part 344 move along the L2 direction, then the 2nd link 342 is further swung, and will lift on the 1st link 341, and the top of lobe plate 37 in Figure 17 is moved further.Then, if make limiting part 344 move to the mobile terminal of L2 direction, then lobe plate 37 moves to top.

Thus, the camming action of the pin 33d of the 1st lens mount 33 by the 1st cam path 37a, forwards (arrow F direction) moves, and arrives the pin 33d among Figure 17 " the position.On the other hand, the camming action of the pin 36d of the 2nd lens mount 36 by the 2nd cam path 37b, rearward (arrow R direction) moves, and arrives the pin 36d among Figure 17 " the position.At this moment, optical facilities 30 (the 1st lens mount 33) are positioned from the surface of main body 300 with the camera site of at utmost outstanding wide-angle side end shown in Fig. 4 and Figure 19 C.

On the other hand, if state from then on makes limiting part 344 move along the L1 direction on the contrary, then the 2nd link 342 is pushed back, optical facilities 30 begin to retreat, and arrive the camera site of long burnt end.In addition, if be in the state of any position at limiting part 344, cover plate 304 is closed, then the 2nd link 342 and the 1st link 341 begin to turn back to the original position, and in the moment that the 2nd link 342 and limiting part 344 break away from, to the power failure of CCD24.Optical facilities 30 also turn back to the off-position of withdrawal.

Like this, the operator is the action by cover plate 304 is opened only, just optical facilities 30 are positioned the camera site, can take by CCD24, only pass through the operation of limiting part 344, just can carry out from the camera site of long coke side end, arrive the continuous zoom action of the camera site of wide-angle side end.

So, when taking, needn't require the beamhouse operation of trouble, only by opening cover plate 304, but just can enter shooting state at once, thus, can make the time lag when taking minimum, obtain portable phone with convenience.In addition,, just grow the switching of burnt shooting～wide angle shot serially, needn't when changing coverage, little by little change shooting distance only by suitably adjusting the position of limiting part 344.

In the above-described embodiments, varifocal optical system has been adopted in optical facilities 30, but, even be single-focusing optical facilities, still can be by linking with cover plate 304, optical facilities 30 are positioned the camera site, and then, can switch smoothly and take action by making the on/off action interlock of CCD24.In addition, in the above-described embodiments, the driving mechanism that changes the enlargement factor of optical facilities 30 has adopted the camming action of lobe plate 37, but is not limited to this, also can adopt other mechanism.

In addition, in the above-described embodiments, though expression is and the interlock of the on-off action of cover plate 304, the structure of driving cam plate 37, but also can form tooth bar on lobe plate 37, will be connected with the motor driver of the pinion wheel of this tooth bar engagement and motor etc., linking by the on-off action with cover plate 304 makes switch connection/disconnection, thus, can realize that electricity drives.

In addition, in the above-described embodiments,, be not limited to this, also can adopt portable personal computer with structure identical etc. with cover plate though be portable phone as what be fit to adopt portable information terminal expression of the present invention.

As mentioned above, if adopt this portable information terminal, then can be only by cover plate 304 is opened and closed, just optical facilities 30 are positioned camera site and accommodated position.In addition, by varifocal optical system is made in optical facilities 30, so can under the situation that does not change the camera site, carry out from long burnt zoom shot to wide-angle.

Also have, spring 343 formations such as grade because link gear by link 341,342, links so make designs simplification, can realize miniaturization, lightweight.

Have again, owing to be provided with limiting part 344, even so under the situation that cover plate 304 is opened fully, still optical facilities 30 can be stopped at the camera site of regulation, in addition, and then can adjust, so can be at the coverage from long coke side end to the wide-angle side end, the zoom operation that carries out optical facilities by the position.

In addition, just begin power supply when making optical facilities 30 be positioned at the camera site, only just can take at once, the time lag before can reducing to take by the opening action of cover plate 304 to CCD24.

In addition, owing to cover optical facilities 30 by cover plate 304, so obviously, can prevent the shading to CCD24, adhering to of the fingerprint of the lens surface of optical facilities 30 or dust etc. because of the dual-purpose of cover plate 304, can realize the minimizing of number of components, the reduction of cost etc.

Figure 20 A, 20B～Figure 23 represent the another embodiment (being portable phone here) of portable information terminal of the present invention.In addition, the difference of photograph mechanism 20 ' (optical facilities 30 ') and aforesaid photograph mechanism 20 (optical facilities 30) only is to form the lobe plate and the housing of driving mechanism, other is identical with aforesaid Fig. 2's～shown in Figure 4, for same structure, omits and describes.
