  According to the first aspect of the present invention, the first case having the display unit and the second case having the key input unit are connected to each other by the connecting unit including the photographing unit so as to be opened and closed. When the two cases are opened, the display surface of the display unit and the input surface of the key input unit face the same direction, and the photographing direction of the photographing unit faces the opposite direction with respect to the display surface and the input surface. The display surface of the display unit can be directed in the direction opposite to the shooting direction of the shooting unit with a simple operation by simply opening the case.

  For this reason, when taking a picture, it is possible to take a picture while looking at the image of the subject displayed on the display unit, and it is possible to hold one of the first and second cases in a natural state, so that the entire device has it. In addition to being easy to operate and having a zoom function unit, the shooting range of the subject can be adjusted while viewing the image of the subject displayed on the display unit. It is possible to obtain a good image of the subject. Further, since it is only necessary to connect the first and second cases so as to be openable and closable by the connecting part incorporating the photographing part, it is possible to obtain an inexpensive structure.

  According to the second aspect of the present invention, since the connecting portion is provided in a direction perpendicular to the display surface of the display portion and the input surface of the key input portion, the first, Since only one of the second cases is rotatably attached and the other of the first and second cases is only rotatably attached or fixed to the other end of the connecting portion, the connecting structure is simple. At this time, in a state where the first and second cases are overlapped, the connecting portions may be connected so that the display portion of the first case is always exposed. In this way, the first and second cases can be opened and closed by rotating the first and second cases along the surface direction of the display surface and the input surface around the connecting portion. Since the display unit is always exposed, the information displayed on the display unit can be freely viewed at any time regardless of whether the first and second cases are opened or closed.

  According to invention of Claim 3, a connection part is orthogonal to this 1st axial part with the 1st axial part provided in the orthogonal | vertical direction with respect to the display surface of a display part, and the input surface of a key input part. One of the first and second cases is rotatably attached to the first shaft portion excluding the portion where the second shaft portion is provided, and the second shaft portion is provided with the second shaft portion. 1. The other of the first and second cases is attached to the other side (for example, the first case) with the other side of the first and second cases (for example, the second case) centered on the first shaft portion. On the other hand, it can be relatively rotated along each surface direction of the display surface and the input surface, and the other of the first and second cases (for example, the first case) is centered on the second shaft portion. It can be rotated in the direction that stands up with respect to the second case) In addition to being able to open the first and second cases, the other of the first and second cases is further rotated around the first shaft portion while the other of the first and second cases is raised. Thus, the orientation of the display surface of the display unit and the input surface of the key input unit can be changed.

  Thus, when the first and second cases are overlapped and closed, the display surface of the display unit and the input surface of the key input unit can be directed in the same direction, and the display surface of the display unit and the key input unit The first and second cases can be overlapped and closed in any state. At this time, when the first and second cases are overlapped with the display surface of the display unit and the input surface of the key input unit facing in the same direction, the image is taken as in the invention of claim 1. Since the shooting direction of the display unit can be directed in the direction opposite to the display surface of the display unit, even when the first and second cases are overlapped and closed, shooting is performed while viewing the subject image displayed on the display unit. Can do.

  According to the fourth aspect of the present invention, when the zoom function unit of the photographing unit zooms in a direction perpendicular to the display surface of the display unit and the input surface of the key input unit, the photographing unit has the zoom function unit. However, the display unit of the first case and the key input unit of the second case are not restricted by the zoom function unit of the photographing unit, and each installation area of the display unit and the key input unit is defined in the first and second cases. Each can be secured sufficiently.

  According to the fifth aspect of the present invention, since the external operation element for zooming the zoom function unit is provided on one side surface of the first and second cases, the external operation element is a display unit or a key input unit. In this way, it is possible to secure a sufficient installation area for the display unit and the key input unit, and in particular, an external operation element is provided on one of the side surfaces of the first and second cases. As a result, the external operator is always exposed to the outside even when the first and second cases are overlapped and closed, or the first and second cases are opened to each other. And it can operate satisfactorily.

  In this case, for example, if the external operation element is provided on one side surface of the first and second cases located in the vicinity of the connecting portion, the first and second cases are closed and overlapped with each other. Even if you hold two cases with both hands, or with one hand holding one of the first and second cases with the first and second cases open to each other, for example, the second case having a key input section, Since the finger is naturally arranged at a position where it comes into contact with the external operation element, the external operation element can be operated satisfactorily and reliably during photographing.

  According to the sixth aspect of the present invention, the external operation element operates the zoom function unit of the photographing unit when it is half-pressed, and captures an image of the subject with the photographing unit when the external operation unit is fully depressed. Since the zoom function of the shooting unit operates when the control is half-pressed, the subject angle can be set by adjusting the shooting range of the subject when the external control is pressed halfway. When the external operation element is completely pushed in, the image of the subject is captured by the photographing unit, so that the subject image can be favorably photographed at a desired angle.

  According to the invention described in claim 7, the motor unit for zoom driving the zoom function unit of the photographing unit, the external operator provided on one of the first and second cases, and the operation of the external operator In response to the operation, the drive rotation of the motor unit is transmitted to one of the first and second cases to open and close the first and second cases, thereby operating the external operator. Then, in response to the operation of the external operation element, the rotation transmitting unit transmits the driving rotation of the motor unit to one of the first and second cases, and the first and second cases are relatively opened and closed around the rotation axis. Therefore, the first and second cases can be opened and closed easily and automatically by a one-touch operation, and the drive source of the zoom function unit is used, so the first and second cases can be opened and closed relatively. This eliminates the need for a dedicated drive source. It is possible to minimize the number, it is possible to achieve even lower cost.

  According to the invention described in claim 8, the detection means for detecting the relative open / close state of the first and second cases, and the display form of the display unit are controlled based on the detection signal detected by the detection means. And a control means, so that when the first and second cases rotate relative to each other about the connecting portion, the open / close state is detected by the detection means, and based on the detected detection signal. Since the control means controls the display form of the display unit, the display state of the display unit can be automatically changed to the vertical display or the horizontal display according to the open state of the first and second cases.

  For example, when the first and second cases are rotated by the connecting portions along the respective surface directions of the first and second cases, the first and second cases are relatively rotated by 90 ° and opened. The information displayed on the display is automatically displayed in landscape orientation, and the information displayed on the display is automatically displayed in portrait orientation when the first and second cases are rotated by 180 ° relative to each other and opened. Thus, even if the opening angle of the first and second cases changes, it is possible to make information such as an image displayed on the display unit easier to see.

  According to the ninth aspect of the invention, since the flash unit that emits a flash toward the subject to be photographed by the photographing unit is provided, it is possible to irradiate the subject with light emitted from the flash unit during photographing. This makes it possible to photograph the subject satisfactorily and clearly even in a dark place.

  According to the tenth aspect of the invention, the flash unit includes the light irradiation adjusting mechanism that varies the radiation direction or the light emission range of the light emitted from the flash unit according to the photographing state of the photographing unit. The emission direction of the emitted light or the emission range of the light can be adjusted by the light irradiation adjustment mechanism, so that the light of the flash part can be efficiently directed toward the subject. The subject can be illuminated brightly and uniformly both when shooting a subject and when shooting a subject with a short focal length.

Also in this case, the second transmission gear 38 rotates together with the second intermediate gear 35 of the second rotating shaft 36 without the second slip mechanism 37 slipping in a normal state where a predetermined load or more is not applied. Thus, the driving rotation of the motor 20 is transmitted to the ring gear 26 of the first case 1 to rotate the second case 2 relative to the first case 1, and the second transmission gear 38 is loaded more than a predetermined load. As a result, the second slip mechanism portion 37 slips, thereby causing the second intermediate gear 35 of the second rotating shaft 36 to idle, so that the drive rotation of the motor 20 is not transmitted to the ring gear 26 of the second case 2. It is configured.

  The switching lever 27 detachably locks one of the first and second transmission gears 33 and 38 in accordance with the operation of the operation switch 8 provided in the second case 2 and applies a load exceeding a predetermined value. The rotation of the motor 20 is transmitted to one of the first and second transmission gears 33 and 38. That is, as shown in FIGS. 9 and 10, the switching lever 27 is disposed in the vicinity of the first and second transmission gears 33 and 38, and is in the first state when the operation switch 8 is half-pressed. The first transmission gear 33 is locked, the driving rotation of the motor 20 is transmitted to the second transmission gear 38, the second case 2 is rotated relative to the first case 1 together with the ring gear 26, and the operation switch 8 Is in the second state in which the first transmission gear 33 is completely pushed, the second transmission gear 38 is locked by releasing the locking to the first transmission gear 33, and the drive rotation of the motor 20 is transmitted to the first transmission gear 33. The rotating cylinder 19 of the zoom mechanism unit 18 is configured to rotate.

  By the way, relative rotation angles of the first and second cases 1 and 2 are detected on the opposing surfaces of the first and second cases 1 and 2 in the vicinity of the rotating shaft 3 as shown in FIGS. An optical sensor unit 39 is provided. The optical sensor unit 39 includes a light emitting element 40 provided in the first case 1 and a plurality of light receiving elements 41 a to 41 c provided in the second case 2. In this case, the plurality of light receiving elements 41 a to 41 c are provided at predetermined positions corresponding to the rotational movement locus of the light emitting element 40. For example, the first light receiving element 41a is provided at the first position corresponding to the light emitting element 40 when the first and second cases 1 and 2 are overlapped with each other, and the second light receiving element 41b is the first, When the second cases 1 and 2 are relatively rotated by about 90 °, the light emitting element 40 is provided at the corresponding second position, and the first and second cases 1 and 2 are relative to each other in the third light receiving element 41c. Thus, the light emitting element 40 is provided at the corresponding third position when rotated by about 180 °.

  Accordingly, as shown in FIGS. 1 to 3, in the optical sensor unit 39, when the first and second cases 1 and 2 are overlapped and closed, the light emitting element 40 faces the first light receiving element 41 a. Then, the light emitted from the light emitting element 40 is received by the first light receiving element 41a, thereby detecting that the first and second cases 1 and 2 are overlapped. Further, as shown by a two-dot chain line in FIG. 4, when the first and second cases 1 and 2 are relatively rotated by about 90 °, the light emitting element 40 faces the second light receiving element 41b and the light emitting element 40 When the second light receiving element 41b receives the light emitted in step 1, it is detected that the first and second cases 1 and 2 are opened by about 90 °. Further, as shown by a solid line in FIG. 4, when the first and second cases 1 and 2 are relatively rotated by about 180 °, the light emitting element 40 is opposed to the third light receiving element 41c and emits light by the light emitting element 40. By receiving the received light by the third light receiving element 41c, it is detected that the first and second cases 1 and 2 are in an open state of about 180 °.

Next, the circuit configuration of this mobile phone will be described with reference to FIG.
The circuit of the cellular phone includes a CPU (Central Processing Unit) 45 that controls the entire circuit, an image processing circuit 46 that processes an image signal from the image sensor 17 such as a CCD, and a zoom mechanism unit 18 of the photographing unit 4. , And a motor driving circuit 47 for controlling the driving of the zoom motor 20 for rotating the first and second cases 1 and 2 relative to each other, and the light sensor 39 to drive the light receiving elements 41a to 41a. A detection circuit 48 for processing a detection signal from 41c, a switch circuit 49 for processing an electrical signal corresponding to the switch operation of the operation switch 8 and the shutter switch 9, and a display unit 5 for displaying information such as telephone information and photographed images Display drive circuit 50 for controlling the driving of the mobile phone, input processing circuit 51 for processing input signals from the operation unit 6 and the key input unit 7, and transmission of call information and image information Processing the broadcast and a receiving circuit 52 for processing the received signal received by the antenna 10 and sends to the antenna 10.

Next, an operation flow of display switching control processing and zoom processing of the mobile phone will be described with reference to FIGS.
As shown in FIG. 12, in the display switching control process of the mobile phone, when this process flow starts, it is determined whether or not the operation switch 8 is operated and the first state is half-pressed (step S1). If the operation switch 8 is not operated at this time, it waits until the operation switch 8 is operated. In addition, when the operation switch 8 is operated and half-pressed in this step S1, the switching lever 27 of the rotation transmission portion 23 interlocks with this and the first transmission gear 33 is locked and the idling state. In addition, the drive rotation of the motor 20 can be transmitted to the ring gear 26 of the second case 2 via the second transmission wheel 25, and the motor 20 is driven and rotated in this state to move the second case 2 to the first case 2. Rotate relative to case 1.

  And it is judged whether the relative rotation angle of the 1st, 2nd cases 1 and 2 is 90 degrees or less (step S2). At this time, the light emitting element 40 of the optical sensor unit 39 corresponds to which of the plurality of light receiving elements 41a to 41c, and which of the light receiving elements 41a to 41c outputs the detection signal, The relative rotation angle of 2 is determined. That is, the light emitting element 40 corresponds to the first light receiving element 41a and a detection signal is output from the light receiving element 41a, or the light emitting element 40 corresponds to the second light receiving element 41b and detected from the light receiving element 41b. When the signal is output, the relative rotation angle of the first and second cases 1 and 2 is determined to be 90 ° or less, and the display state of the display unit 5 is set to the horizontally long state (the solid line display unit 5 shown in FIG. (Refer to Reference) (step S3), and this flow ends. In addition, when the light emitting element 40 of the optical sensor unit 39 corresponds to the third light receiving element 41c and a detection signal is output from the light receiving element 41c, the relative rotation angles of the first and second cases 1 and 2 are changed. It is determined that the angle is 180 °, the display state of the display unit 5 is switched to the vertically long state (step S4), and this flow is finished.

  Further, in the zoom control process of the cellular phone, as shown in FIG. 13, when this process flow starts, it is determined whether or not the operation switch 8 is operated and the second state is fully depressed (step S5). . At this time, if the operation switch 8 is not in the fully depressed state, this flow is terminated. Further, when the operation switch 8 is fully pushed, the switching lever 27 of the rotation transmission unit 23 engages with the second transmission gear 38 in an idle state in conjunction with this, and the motor 20 The driving rotation of the zoom mechanism 18 is transmitted to the rotary cylinder 19 of the zoom mechanism 18 by the first transmission wheel 24. In this state, the motor 20 is driven and rotated to zoom control the zoom mechanism 18 of the photographing unit 4 (step S6).

  At this time, as shown in FIGS. 6 and 7, the motor 20 of the zoom mechanism 18 of the photographing unit 4 is rotated forward, and the rotation of the motor 20 is driven by the drive gear 22, the first transmission wheel 24 of the rotation transmission unit 23, When transmitted to the rotating cylinder 19 via the driven gear 21, the rotating cylinder 19 in the state shown in FIG. 6 rotates in the direction of the arrow X shown in FIG. As a result, the first and second spiral grooves 19a and 19b of the rotary cylinder 19 are rotationally moved so that the first and second protrusions 12a and 13a of the first and second lens frames 12 and 13 are guided into the guide holes of the lens barrel 11. 11a, the first and second lens frames 12 and 13 move together with the first and second lenses 14 and 15 toward the outside of the rotating shaft 3 to move the subject. The first lens 14 is projected out of the rotating shaft 3 to take a telephoto state in order to magnify the image, and this flow is terminated.

  Next, a case where such a mobile phone is used will be described. Since this cellular phone has a telephone function and a photographing function, communication can be performed by the telephone function, and a subject can be photographed by the photographing function. You can display it. That is, when communicating by the telephone function, as shown by the solid line in FIGS. 4 and 5, the first and second cases 1 and 2 are relatively substantially aligned along the direction of each surface around the rotation shaft 3. The first and second cases 1 and 2 are opened to each other by rotating 180 °.

  As a result, as shown by a solid line in FIG. 4, the key input unit 7 of the second case 2 is exposed in the same direction as the display surface of the display unit 5 of the first case 1. In this state, an input operation is performed on the operation unit 6 and the key input unit 7 to transmit an e-mail to the communication partner, to talk with the communication partner, or to transmit a photographed subject image as described later. Can do. At this time, since the photographing unit 4 is stored in the rotary shaft 3 without projecting from the rotary shaft 3 to the outside, the photographing unit 4 is not damaged or disturbed at the time of communication and can be used well. it can.

  When the subject is photographed by the photographing unit 4, as shown in FIGS. 1 to 3, the first and second cases 1 and 2 are overlapped and closed, and the first and second cases 1 are closed in this state. Hold 2 sideways with both hands sandwiched from both sides. At this time, when the display unit 5 of the first case 1 is directed to the user side, the photographing unit 4 provided in the rotation shaft 3 faces the subject side. In this state, when the operation switch 8 provided on the side surface of the second case 2 located in the vicinity of the rotation shaft 3 is completely pushed into the second state, the motor 20 of the zoom mechanism portion 18 is driven and rotated, Since the first and second lenses 14 and 15 are moved from the rotary shaft 3 to the outside, the photographing unit 4 is in the telephoto state.

  That is, when the operation switch 8 is completely pushed in, the switching lever 27 of the rotation transmission unit 23 locks the second transmission gear 38 in conjunction with the operation switch 8 as shown in FIGS. In addition to the idling state, the drive rotation of the motor 20 can be transmitted to the rotary cylinder 19 of the zoom mechanism unit 18 by the first transmission wheel 24. 6 and 7 (see FIG. 2A), the motor 20 of the zoom mechanism unit 18 rotates in the forward direction, and the forward rotation of the motor 20 is the first transmission of the drive gear 22 and the rotation transmission unit 23. This is transmitted to the rotary cylinder 19 via the wheel 24 and the driven gear 21, and the rotary cylinder 19 rotates in the direction of the arrow X shown in FIG.

  As a result, the first and second spiral grooves 19a and 19b of the rotating cylinder 19 rotate and move, and as shown in FIG. 8, the first and second spiral grooves 19a and 19b become the first and second lens frames 12 and 13, respectively. The first and second projections 12a and 13a are moved along the guide hole 11a of the lens barrel 11, respectively, so that the first and second lens frames 12 and 13 are rotated together with the first and second lenses 14 and 15. 3 (see FIG. 2B), the photographing unit 4 is in the telephoto state. At this time, the image of the subject projected on the image sensor 17 by the first and second lenses 14 and 15 is converted into an electrical signal by the image sensor 17 and captured as an image signal, and displayed based on the captured image signal. Since the image of the subject is displayed on the unit 5, the subject can be photographed by operating the shutter switch 9 while viewing the displayed image.

  Further, in this mobile phone, it is not always necessary to shoot with the first and second cases 1 and 2 overlapped and closed, and the first and second cases 1 and 2 are relatively rotated in the plane direction. Shooting even when the first and second cases 1 and 2 are rotated 90 ° or 180 ° relative to each other and opened, for example, as shown by a two-dot chain line or a solid line in FIGS. Can do. At this time, if the palm of the left hand is applied to the back side of the second case 2 and the second case 2 is gripped with the left hand, the thumb of the left hand is disposed at a position where it touches the operation switch 8 and the shutter switch 9. The operation switch 8 and the shutter switch 8 can be easily operated while holding the second case 2 with one hand.

  For this reason, in this state, when the operation switch 8 is half-pressed to the first state, the switching lever 27 of the rotation transmission unit 23 locks the first transmission gear 33 to drive the motor 20 to rotate the second transmission wheel 25. Is transmitted to the ring gear 26 of the second case 2, so that the first and second cases 1 and 2 are relatively rotated and opened as shown in FIGS. 4 and 5. In this state, when the operation switch 8 is fully depressed, the motor 20 of the zoom mechanism unit 18 is driven to bring the photographing unit 4 into the telephoto state. Thereafter, the subject can be photographed by pressing the shutter switch 9. Also at this time, the subject image can be displayed on the display unit 5 and the subject can be photographed while viewing the displayed image.

  As described above, according to this mobile phone, the first case 1 having the display unit 5 and the second case 2 having the key input unit 7 are connected by the rotary shaft 3 so as to be openable and closable. Since the photographing unit 4 having the mechanism unit 18 is provided on the side opposite to the display surface of the display unit 5 so that the photographing direction is directed, the first and second cases 1 and 2 are attached to the rotary shaft 3 when photographing. The photographing direction of the subject by the photographing unit 4 can be directed in the direction opposite to the display surface of the display unit 5 in the opened state or the closed state. Therefore, the subject can be photographed while viewing the image of the subject displayed on the display unit 5, and the zoom mechanism unit 18 is zoomed in the axial direction of the rotation shaft 3 by the drive rotation of the motor 20, so that the display unit The shooting range of the subject can also be adjusted while viewing the image of the subject displayed in FIG. 5, thereby making the shooting operation simple and easy.

  In this case, since the first and second cases 1 and 2 are simply connected to each other via the rotating shaft 3 with the photographing unit 4 built in, the structure is simple and inexpensive. In response to the operation of the operation switch 8, the rotation transmitting unit 23 transmits the driving rotation of the motor 20 to the second case 2 to relatively rotate the first and second cases 1 and 2 around the rotation shaft 3. Therefore, the first and second cases 1 and 2 can be opened and closed easily and automatically by a one-touch operation. In addition, since the drive source of the zoom mechanism unit 18 is used, a dedicated drive source for relatively rotating the first and second cases 1 and 2 becomes unnecessary, thereby minimizing the number of drive sources. Since it can suppress, cost reduction can also be achieved.

  In particular, since the photographing unit 4 is provided in the rotary shaft 3 that is the rotation center of the first and second cases 1 and 2 so as to be zoomable along the axial direction, the photographing unit 4 includes the zoom function unit 18. However, the display unit 5 of the first case 1 and the key input unit 7 of the second case 2 are not restricted by the zoom function unit 18 of the photographing unit 4, and each installation area of the display unit 5 and the key input unit 7 is not limited. Can be sufficiently secured in the first and second cases 1 and 2, respectively. In this case, since one end of the rotating shaft 3 is provided in the first case 1 without being exposed to the front side of the first case 1, the front surface of the first case 1 corresponding to the rotating shaft 3 is provided. Thus, the operation unit 6 can be arranged, and the installation area of the key input unit 7 can be further widened.

  Further, in this cellular phone, the display unit 5 is provided on the outer surface of the first case 1 that is exposed to the outside in a state where the first and second cases 1 and 2 are overlapped and closed. Even when the first and second cases 1 and 2 are rotated in the plane direction at the center and overlapped with each other and closed, the first and second cases 1 and 2 are rotated in the plane direction around the rotation shaft 3. Even in a state where they are open to each other, the display surface of the display unit 5 can always be exposed to the outside, so that the information displayed on the display unit 5 can be freely viewed at any time. In particular, since the photographing unit 4 is provided in the rotary shaft 3 with its photographing direction facing away from the display surface of the display unit 5, the first and second cases 1 and 2 are overlapped and closed. However, even when the first and second cases 1 and 2 are opened to each other in the plane direction, it is possible to shoot well while looking at the image of the subject displayed on the display unit 5 at the time of shooting. You can get things.

  In this case, since the key input unit 7 is provided in the second case 2 so as to face the same direction as the display surface of the display unit 5, the first and second cases 1 and 2 are rotated in the plane direction and opened. In this state, the key input unit 7 is exposed in the same direction as the display surface of the display unit 5, so that the key input unit 7 can be operated by keys while viewing the display unit 5. Further, when the first and second cases 1 and 2 are overlapped and closed, the first case 1 is disposed so as to overlap the surface of the key input unit 7, so that the key input unit 7 is protected by the first case 1. For this reason, when the first and second cases 1 and 2 are carried in a state of being overlapped and closed, malfunction of the key input unit 7 can be prevented.

  Further, since the operation switch 8 and the shutter switch 9 are provided on the side surface of the second case 2, the operation switch 8 and the shutter switch 9 do not restrict the display unit 5 and the key input unit 7. In addition to ensuring a sufficient installation area for the unit 5 and the key input unit 7, the operation switch 8 and the shutter switch 9 are always exposed to the outside, so the first and second cases 1 and 2 are overlapped and closed. Since the operation switch 8 and the shutter switch 9 can be operated even in the opened state or in a state where the first and second cases 1 and 2 are relatively opened in the plane direction, the operation switch 8 can be freely operated at any time. In addition, the shutter switch 9 can be operated, and this is also convenient.

  In this case, the operation switch 8 and the shutter switch 9 are provided on the side surface of the second case 2 located in the vicinity of the rotating shaft 3, so that the first and second cases 1 and 2 are connected as shown in FIG. 1. The second case can be held with both hands in an overlapped and closed state, or with the first and second cases 1 and 2 relatively rotated in the plane direction and opened as shown in FIG. 2 with one hand from the back side, the finger of that hand can be brought into contact with the operation switch 8 and the shutter switch 9 in a natural state, so that the operation switch 8 and the shutter switch 9 can be easily and at the time of shooting. It can be operated reliably.

  In the first state where the operation switch 8 is half-pressed, the switching lever 27 of the rotation transmission unit 23 engages the first transmission gear 33 to make it idle, and the motor 20 is driven to rotate. The first transmission case 25 can be transmitted to the ring gear 26 of the second case 2 by the second transmission wheel 25 to relatively rotate the first and second cases 1 and 2, and when in the fully pushed second state, The switching lever 27 engages the second transmission gear 38 to make it idle, and the driving rotation of the motor 20 is transmitted to the zoom mechanism unit 18 of the photographing unit 4 by the first transmission wheel 24 to cause the zoom mechanism unit 18 to move. The zooming operation is performed, so that the photographing unit 4 is brought into the telephoto state, and the angle of the subject can be set by adjusting the photographing range of the subject.

  Therefore, the opening / closing operation of the first and second cases 1 and 2 and the zooming operation of the zoom mechanism 18 can be selected with one operation switch 8, whereby the first, second case 1, 2 can be opened and closed, and the zoom mechanism 18 can be zoomed, and the number of switches can be minimized, thereby reducing the number of parts and reducing the cost.

  Further, in this mobile phone, the first and second cases 1 and 2 are rotated around the rotation shaft 3 so as to overlap each other and closed, and the first and second cases 1 and 2 are relatively 90 °. When in the opened state, the display unit 5 of the first case 1 switches to landscape display, and the first and second cases 1 and 2 are rotated by 180 ° relative to the rotation axis 3 and opened. Since the display unit 5 of the first case 1 is switched to the vertically long display when in the state, the state in which the first and second cases 1 and 2 are overlapped with each other, and the first and second cases 1 and 2 are relatively When shooting in the open state after being rotated by 90 °, the subject image can be viewed in a horizontally long state, and the first and second cases 1 and 2 are rotated and rotated by 180 ° and taken in the open state. The subject image can be viewed in a portrait orientation.

  As a result, the display form of the display unit 5 is automatically switched to the vertical display or the horizontal display according to the opening angle of the first and second cases 1 and 2. Even if the opening angle changes, information such as an image displayed on the display unit 5 can be easily viewed. In this case, particularly when the operation switch 8 is half-pressed, the rotation rotation of the motor 20 for zooming the zoom mechanism 18 of the photographing unit 4 is applied to the ring gear 26 of the second case 2 by the rotation transmitting unit 23. Simultaneously with the transmission, the relative rotation angles of the first and second cases 1 and 2 are detected by the optical sensor unit 39, and the display form of the display unit 5 is controlled by the CPU 45 based on the detection signal. The first and second cases 1 and 2 can be easily opened and closed by an operation, and the display form of the display unit 5 is automatically displayed vertically in accordance with the opening angle of the first and second cases 1 and 2. The display can be switched to landscape display, and a user-friendly display can be obtained.

(Embodiment 2)
Next, a second embodiment in which the present invention is applied to a mobile phone will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected and demonstrated to the same part as Embodiment 1 shown by FIGS.
This mobile phone has a structure in which the photographing unit 55 has both a telephoto function and a wide-angle function, and has substantially the same structure as that of the first embodiment except for this. That is, the photographing unit 55 is implemented by a zoom mechanism unit 56 that moves the first lens frame 12 that holds the first lens 14 and the second lens frame 13 that holds the second lens 15 along the axial direction. It has a different structure from the zoom mechanism portion 18 of the first embodiment.

  The zoom mechanism 56 includes a first spiral groove 57 that moves the first protrusion 12 a of the first lens frame 12 to the inner peripheral surface of the rotary cylinder 19 that is rotatably provided on the outer peripheral surface of the lens barrel 11. A second spiral groove 58 for moving the second protrusion 13 a of the second lens frame 13 is provided. In this case, when the rotary cylinder 19 is rotated in the direction of the arrow X shown in FIG. 14 by the normal rotation of the motor 20, the first spiral groove 57 moves the first lens frame 12 from the rotary shaft 3 to the outside as shown in FIG. It is comprised so that it may move toward (upward in the figure). Further, the second spiral groove 58 allows the second lens frame 13 to be moved from the rotation shaft 3 to the outside (as shown in FIG. 15) when the rotary cylinder 19 is rotated in the direction of the arrow X shown in FIG. The second lens frame 13 is configured to gradually move away from the first lens frame 12 after approaching the first lens frame 12 while moving upward (in the drawing).

  As a result, the zoom mechanism 56 is configured such that the first lens frame 12 and the second lens frame 12 move from the rotary shaft 3 toward the outside (upward in FIG. 14), while the second lens frame 13 moves to the first lens frame 12. The second lens frame 13 moves to the outside (upward in the figure) while the first and second lens frames 12 and 13 move from the rotary shaft 3 toward the outside (upward in the figure). 12 is configured to be in a wide-angle state by moving away from 12 toward the image sensor 17 side in the rotation shaft 3. In the second embodiment, a zoom function switch (not shown) is provided in the vicinity of the shutter switch 9 (see FIG. 1), and the telephoto function and the wide-angle function are switched by this switch. Yes.

  Such a cellular phone has the same effects as those of the first embodiment. In particular, when the telephoto function is selected by operating a changeover switch (not shown), the motor 20 of the zoom mechanism unit 56 rotates in the forward direction. When the rotary cylinder 19 is rotated, the first and second spiral grooves 57 and 58 of the rotary cylinder 19 move the first and second lens frames 12 and 13 toward the outside of the rotary shaft 3 while moving the second lens. Since the frame 13 is brought close to the first lens frame 12, the telephoto state is set, and thus telephoto shooting can be performed. Further, when the wide-angle function is selected by operating the changeover switch, if the motor 20 of the zoom mechanism unit 56 rotates forward to rotate the rotating cylinder 19, the first and second spiral grooves 57, 58 of the rotating cylinder 19 are rotated. While moving the first and second lens frames 12 and 13 toward the outside of the rotation shaft 3, the second lens frame 13 is once brought close to the first lens frame 12 and then the imaging element 17 is moved from the first lens frame 12. Since it is separated toward the side, it becomes a wide-angle state, so that wide-angle shooting can be performed.

(Embodiment 3)
Next, a third embodiment in which the present invention is applied to a mobile phone will be described with reference to FIGS. Also in this case, the same portions as those in the first embodiment shown in FIGS.

Is provided.

  The second case 2 is formed in a size that is substantially the same size as the first case 1. As in the first embodiment, a key input unit 7 and a microphone unit 54 are provided on the opposite surface of the second case 2 where the first case 1 overlaps (see FIG. 4). Further, as in the first embodiment, a shutter switch 9 is provided on the side surface on the upper side in the second case 2 shown in FIG. An antenna 10 is provided so that it can appear and disappear. Also in this case, the key input unit 7 includes various keys necessary for telephone functions such as a numeric keypad, a memo key, and a manner key, and each key faces the first case 1 in the vertically long state of the second case 2. The two cases 2 are arranged vertically on the facing surface.

  As shown in FIG. 16, the shutter switch 9 is provided on the side surface on the upper side of the second case 2 located in the vicinity of the rotation shaft 3, and when the shutter switch 9 is half pressed, the zoom function of the photographing unit 60 is performed. Is operated to output a switch signal for adjusting the focal length with respect to the subject and the light emission direction by the first and second strobe units 61 and 62, and the first state when the second state is fully pushed. The second strobe units 61 and 62 are caused to emit light, and the photographing unit 60 is configured to output a switch signal for capturing the subject image.

It is configured to be in a state of being opened by rotating at a predetermined angle, for example, 90 ° or 180 °. The first and second cases 1 and 2 are electrically connected by a connecting member (not shown) via the rotating shaft 3.

  The photographing unit 60 has an autofocus function (autofocus function) and a zoom function unit. As shown in FIG. 17, the photographing unit 60 is in a state in which the photographing direction is directed to the back side of the second case 2, that is, the first case 1.

And a zoom mechanism unit 70 that performs zoom movement along the three axial directions.

  In this case, in the photographing unit 60, the first to third lens frames 63 to 65 move along the axial direction in the rotation shaft 3, and the first lens frame 63 protrudes and protrudes toward the back side of the second case 2. It is configured to. As shown in FIG. 17, the imaging unit 69 includes a housing 71 fixed in the rotary shaft 3, and a configuration in which an imaging element 74 such as a CCD is disposed in the housing 71 via a crystal filter 72 and a protective glass 73. It has become. The image sensor 74 is disposed on the optical axis 4a that is the axis center of the rotation shaft 3, and is configured to convert the image of the subject projected by the first to third lenses 66 to 68 into an electrical signal and output it. ing. The first and second lenses 66 and 67 are lenses for a zoom function, and the third lens 68 is a lens for adjusting the focal length.

  The first to third lens frames 63 to 65 are each formed in a cylindrical shape as shown in FIGS. 17 to 19, and the first lens frame 63 is movably accommodated in the second lens frame 64. The second lens frame 64 is movably accommodated in the third lens frame 65, and the third lens frame 65 is movably accommodated in the rotation shaft 3. In this case, slit-like guide holes 75 and 76 for guiding the first and second lens frames 63 and 64 along the axial direction are provided on the peripheral surfaces of the second and third lens frames 64 and 65 in the axial direction. It is provided along. A guide projection is provided on the outer peripheral surface of the first lens frame 63 so as to be inserted into the guide hole 75 of the second lens frame 64 and into the guide hole 76 of the third lens frame 65. A guide protrusion is provided on the outer peripheral surface of 64 to be inserted into the guide hole 76 of the third lens frame 65.

  As shown in FIGS. 17 to 19, the zoom mechanism unit 70 is provided in the photographing unit 60 and is based on the measurement results of a distance measuring unit 93 (see FIG. 22) that measures the distance to the subject. A cylindrical electromagnetic coil portion 77 for moving the three lens frames 63 to 65 by magnetic force is provided. The electromagnetic coil portion 77 is formed by arranging a large number of coil portions 77a to 77j in a cylindrical shape and is arranged concentrically in a recess 3b provided on the inner peripheral surface of the rotating shaft 3, and in this state, each coil portion Each coil part 77a-77j is comprised so that a magnetic field may be each independently generated by sending an electric current selectively to 77a-77j. In addition, first to third permanent magnets 78 to 80 are provided on the distal ends of the guide protrusions of the first and second lens frames 63 and 64 and the outer peripheral surface of the third lens frame 65, respectively. It is provided in a state close to the inner peripheral surface. In this case, the first to third permanent magnets 78 to 80 are configured to correspond to any one of the coil portions 77 a to 77 j of the electromagnetic coil portion 77.

  The zoom mechanism unit 70 drives the electromagnetic coil unit 77 according to the distance to the subject measured by the distance measuring unit 93, thereby moving the first to third lens frames 63 to 65 to the first to third lenses 66 to 66. 68 is configured to move along the optical axis 4a which is the central axis of the rotating shaft 3. That is, when the zoom mechanism unit 70 drives the electromagnetic coil unit 77 based on the measurement result by the distance measuring unit 93, a current flows selectively through each of the coil units 77a to 77j to generate a magnetic field. The first to third permanent magnets 78 to 80 are attracted according to the magnetic field, and when the coil portions 77a to 77j through which current flows are sequentially changed in this state, the first to third permanent magnets 78 to 78 are changed accordingly. 80 is configured to move along the axial direction of the rotary shaft 3.

  For example, when the first lens 66 is zoomed (moved toward the outside of the electromagnetic coil unit 77 (left side in FIG. 18)) from the initial position (the state of FIG. 18 housed in the electromagnetic coil unit 77), In the initial position shown in FIG. 18, the first permanent magnet 78 of the first lens frame 63 causes a current to flow through the coil part 77d of the corresponding electromagnetic coil part 77 to generate a magnetic field, and then the outer side adjacent thereto (FIG. 18). Then, when a current is passed through the coil portion 77c on the left side to generate a magnetic field, the first permanent magnet 78 is attracted to the coil portion 77c, and thereafter, the coil portion on the outer side (left side in the figure) adjacent thereto. When a current is passed through 77b to generate a magnetic field, the first permanent magnet 78 is attracted to the coil portion 77b. In this way, as shown in FIGS. 18 and 19, the first lens 66 is positioned from the position of the coil portion 77d of the electromagnetic coil portion 77 where the first permanent magnet 78 of the first lens frame 63 is the initial position. It moves to the position of the external coil part 77a.

  Further, when the second lens 67 is zoomed (moved toward the outside of the electromagnetic coil unit 77) from the initial position (the state of FIG. 18 housed in the electromagnetic coil unit 77), the initial position shown in FIG. In FIG. 18, the second permanent magnet 79 of the second lens frame 64 causes a current to flow through the coil portion 77g of the corresponding electromagnetic coil portion 77 to generate a magnetic field, and then the outer (left side in FIG. 18) adjacent coil portion. When a current is passed through 77f to generate a magnetic field, the second permanent magnet 79 is attracted to the coil part 77f, and then a current is further passed through the coil part 77e on the outer side (left side in the figure) adjacent thereto. When the magnetic field is generated, the second permanent magnet 79 is attracted to the coil portion 77e. Thus, as shown in FIGS. 18 and 19, the second lens 67 is external to the position of the coil portion 77g of the electromagnetic coil portion 77 where the second permanent magnet 79 of the second lens frame 64 is the initial position. It moves to the position of the coil portion 77d on the side.

  Further, when the focal length is adjusted by moving the third lens 68, the third permanent magnet 80 of the third lens frame 65 corresponds to the coil portion 77j of the corresponding electromagnetic coil portion 77 at the initial position shown in FIG. After a current is generated to generate a magnetic field, a third permanent magnet 80 is attracted to the coil portion 77i by generating a magnetic field by supplying a current to the outer (left side in FIG. 18) adjacent coil portion 77i. Thereafter, when a magnetic field is generated by passing a current through the coil portion 77h on the outer side (left side in the figure) adjacent to the third permanent magnet 80, the third permanent magnet 80 is attracted to the coil portion 77h. In this way, as shown in FIGS. 18 and 19, the third lens 68 is external to the position of the coil portion 77j of the electromagnetic coil portion 77 where the third permanent magnet 80 of the third lens frame 65 is the initial position. It moves to the position of the coil portion 77g on the side.

  On the other hand, the first and second strobe units 61 and 62 are provided in the vicinity of both sides of the rotating shaft 3 on the back surface of the second case 2 as shown in FIG. As shown in FIGS. 20 and 21, the first and second strobe units 61 and 62 include a light emitting element 81 and a reflector 82 that reflects light from the light emitting element 81. The light emitting element 81 is composed of a light emitting diode (LED). The reflector 82 is formed in a paraboloidal surface or an elliptical curved surface, and the light emitting element 81 is arranged at the focal position thereof, so that the light emitted from the light emitting element 81 is reflected almost parallel to the optical axis 82a of the reflector 82. It is configured. In this case, each reflector 82 is provided with a support shaft 83 on both outer surfaces corresponding to the focal position on the optical axis 82 a, and the support shaft 83 is rotatably supported by the support member 84. The second case 2 is configured to rotate in the left-right direction to change the light emission direction.

  Further, as shown in FIGS. 20 and 21, the first and second strobe units 61 and 62 are light that varies the radiation direction of the light emitted from the light emitting element 81 according to the focal length of the photographing unit 60 at the time of photographing. An irradiation adjustment mechanism 85 is provided. The light irradiation adjusting mechanism 85 drives the strobe motor 86 based on the measurement result of the distance to the subject measured by the distance measuring unit 93, and rotates the drive gear 87 by the strobe motor 86. When the driven gear 88 provided on the support shaft 83 of the reflector 82 is rotated, as shown in FIGS. 21 (a) and 21 (b), the reflector 82 is rotated and the irradiation angle by the reflector 82 is measured. It adjusts according to the focal distance of the imaging | photography part 60 in.

  By the way, on the opposing surfaces of the first and second cases 1 and 2 in the vicinity of the rotating shaft 3, light for detecting the relative rotation angle of the first and second cases 1 and 2, as shown in FIG. A sensor unit 39 is provided. As in the first embodiment, the optical sensor unit 39 includes a light emitting element 40 provided in the first case 1 and a plurality of light receiving elements 41 a to 41 c provided in the second case 2. In this case, the plurality of light receiving elements 41 a to 41 c are provided corresponding to the rotational movement locus of the light emitting element 40. For example, the first light receiving element 41a receives the light corresponding to the light emitting element 40 when the first and second cases 1 and 2 overlap each other, and the second light receiving element 41b includes the first and second cases. When the two cases 1 and 2 are relatively rotated by 90 °, the light emitting element 40 correspondingly receives the light, and the first and second cases 1 and 2 of the third light receiving element 41c are relatively 180 °. The light emitting element 40 correspondingly receives the light when rotated.

  Next, the circuit configuration of this mobile phone will be described with reference to the block diagram shown in FIG. This cellular phone includes a CPU 90 that controls the entire circuit according to a program stored in advance. Around the CPU 90, an image processing circuit 91 that processes an image signal from an image sensor 74 such as a CCD, a zoom drive circuit 92 that drives the zoom mechanism unit 70 of the imaging unit 60, and a subject that is imaged by the imaging unit 60 Measuring circuit 94 for driving the distance measuring unit 93 for measuring the distance to the light emitting element, a light emission driving circuit 95 for driving the respective light emitting elements 81 of the first and second strobe units 61 and 62, and a strobe motor of the light irradiation adjusting mechanism 85. 86, a motor drive circuit 96 for driving 86, a detection circuit 97 for processing a detection signal obtained by driving the optical sensor unit 39, a switch circuit 98 for processing an electrical signal in accordance with the operation of the shutter switch 9, and a telephone A display driving circuit 99 that controls driving of the display unit 5 that displays information such as information and captured images, and an input processing circuit that processes input signals from the operation unit 6 and the key input unit 7 00, and a reception circuit 101 for processing the received signal received by the antenna 10 with processing the transmission information information such as call information, image information sent to the antenna 10.

  The operation flow of the photographing process in this mobile phone will be described with reference to FIG. In this photographing process, when the power switch is turned on and the photographing mode is selected by the operation unit 6, this processing flow starts and the photographing standby state is set (step S10). Then, it is determined whether the shutter switch 9 has been half-pressed (step S11). If the shutter switch 9 has not been half-pressed, the process returns to step S10 to maintain the photographing standby state. When the shutter switch 9 is pressed halfway, the distance measuring unit 93 of the photographing unit 60 measures the distance to the subject (step S12), and the focal length is adjusted based on the measurement result (step S13). At this time, the electromagnetic coil unit 77 of the zoom mechanism unit 70 of the photographing unit 60 is driven by the zoom drive circuit 92, and the first to third lens frames 63 to 65 move in accordance with the measurement result of the distance measuring unit 93. Thus, the focal length of the photographing unit 60 is adjusted.

  That is, in each initial position of the first to third lenses 66 to 68, each coil of the electromagnetic coil unit 77 to which the first to third permanent magnets 78 to 80 of the first to third lens frames 63 to 65 correspond respectively. A current is passed through the portions 77d, 77g, and 77j to generate a magnetic field, and then a current is passed through each of the outer coil portions 77c, 77f, and 77i adjacent to the portions (on the left side in FIG. 18) to generate a magnetic field. The first to third permanent magnets 78 to 80 of the third lens frames 63 to 65 are attracted, respectively, and then a magnetic field is generated by passing a current through the outer coil portions 77b, 77e, and 77h adjacent to the third permanent magnets Then, the first to third permanent magnets 78 to 80 are attracted to the coil portions 77b, 77e, and 77h, respectively. Accordingly, the focal lengths of the first to third lenses 66 to 68 are adjusted by moving the first to third lens frames 63 to 65.

  When the focal lengths of the first to third lenses 66 to 68 are adjusted in this way, the light irradiation adjusting mechanism 85 adjusts the light emission directions by the reflectors 82 of the first and second strobe units 61 and 62 ( Step S14). That is, when the focal length is adjusted, the motor driving circuit 96 drives the strobe motor 86 of the light irradiation adjusting mechanism 85 based on the measurement result obtained by measuring the distance to the subject by the distance measuring unit 93, and this strobe motor 86. As a result, the drive gear 87 is rotated, and the driven gear 88 provided on the support shaft 83 of the reflector 82 is rotated in accordance with this rotation. As a result, the reflectors 82 of the first and second strobe units 61 and 62 rotate about the support shaft 83, and the intersection angle of the optical axis 82a of each reflector 82 with respect to the optical axis 4a of the photographing unit 60 is adjusted. .

  For example, when photographing a far object with a long focal length, as shown in FIG. 24A, the reflector 82 is arranged so that the intersection angle of the optical axis 82 a of the reflector 82 with respect to the optical axis 4 a of the photographing unit 60 becomes small. By reducing the rotation angle, the light emitted from the first and second strobe units 61 and 62 is concentrated toward the subject. Also, when photographing a near subject with a short focal length, as shown in FIG. 24 (b), the reflector 82 is arranged so that the intersection angle of the optical axis 82a of the reflector 82 with respect to the optical axis 4a of the photographing unit 60 becomes large. By increasing the rotation angle, the light emitted from the first and second strobe units 61 and 62 is concentrated toward the subject. When the shutter switch 9 is fully pushed in such a state, the first and second strobe units 61 and 62 emit light, and the light is concentrated and irradiated toward the subject by the reflectors 82. The image of the irradiated subject is captured as image data by the image sensor 74, and this flow is finished.

  Thus, according to this mobile phone, the first case 1 having the display unit 5 and the second case 2 having the key input unit 7 are connected to the first and second cases 1 and 2 by the cylindrical rotating shaft 3. Since the photographing unit 60 having the zoom mechanism unit 70 is provided in the rotation shaft 3 so as to be rotatable along the opposing surfaces of the first and second opposing surfaces, the same effects as the first embodiment can be obtained. A zoom driving unit for moving the zoom mechanism unit 70 of the photographing unit 60 by a magnetic force is used as an electromagnetic coil unit 77 including a large number of coil units 77a to 77j and permanent magnets provided in the first to third lens frames 63 to 65. 78 to 80, the photographing unit 60 can be configured more compactly than the structure in which the zoom mechanism unit is mechanically zoomed, and the zoom mechanism unit 70 of the photographing unit 60 is configured as an electromagnetic coil. 77 and the permanent magnets 78 to 80 are moved by the magnetic force, so that there are few mechanical parts, the structure is simpler than the structure in which the photographing unit 60 operates mechanically, and the impact resistance when carried is high, Failure due to impact can be reduced.

  In this case, the rotary shaft 3 connects the first and second cases 1 and 2 so as to be rotatable in the direction of the surfaces facing each other. The part 7 can be provided in the same plane direction. For this reason, the imaging unit 60 can be provided in the rotating shaft 3 with the imaging direction of the imaging unit 60 facing away from the display surface of the display unit 5. You can shoot. In addition, since the display unit 5 of the first case 1 and the key input unit 7 of the second case 2 are provided in the same plane direction, the second case 2 overlaps the first case 1. Thus, the display unit 5 can always be exposed even when the first and second cases 1 and 2 are closed or opened. For this reason, even when the first and second cases 1 and 2 are closed or opened, the subject can be photographed by the photographing unit 60 while looking at the display unit 5, so that a user-friendly one can be obtained. Can do.

  In this cellular phone, when the photographing unit 60 photographs a subject, the light irradiation adjusting mechanism 85 emits light emitted from the first and second strobe units 61 and 62 according to the focal length of the photographing unit 60 at the time of photographing. The first and second strobe units are controlled by the light irradiation adjusting mechanism 85 both when shooting a long subject with a long focal length and when shooting a close subject with a short focal length. The light emitted from the first and second strobe units 61 and 62 can be irradiated toward the subject by adjusting the irradiation direction of the light emitted by the light sources 61 and 62. For this reason, the light emitted from the first and second flash units 61 and 62 can be efficiently directed toward the subject when shooting a distant subject or when shooting a close subject. As a result, the subject itself can be illuminated brightly, and the subject can be clearly photographed even in a dark place.

  In this case, the first and second strobe units 61 and 62 include two sets of the light emitting element 81 and the reflector 82, and the light irradiation adjusting mechanism 85 has two sets according to the focal length of the shooting unit 60 at the time of shooting. Since the irradiation angle by the reflector 82 is varied, for example, when photographing a long subject with a long focal length, the rotation of the reflector 82 is performed so that the intersection angle of the optical axis 82a of the reflector 82 with respect to the optical axis 4a of the photographing unit 60 becomes small. When shooting an object with a small focal length and a short focal length, the rotation angle of the reflector 82 is increased so that the intersection angle of the optical axis 82a of the reflector 82 with respect to the optical axis 4a of the imaging unit 60 increases. As a result, regardless of whether the focal length is long or short, the light emitted from the first and second strobe units 61 and 62 is surely concentrated and directed toward the subject. Rukoto can, Thus making it possible to brightly and uniformly illuminate an object.

  In the third embodiment, the light irradiation adjusting mechanism 85 drives the strobe motor 86 based on the measurement result of the distance to the subject measured by the distance measuring unit 93, and the drive gear 87 is rotated by the strobe motor 86. Then, the driven gear 88 is rotated by the drive gear 87 and the reflector 82 is rotated about the support shaft 83 of the reflector 82, whereby the irradiation angle by the reflector 82 is made to correspond to the focal length of the imaging unit 60 at the time of imaging. However, the present invention is not limited to this. For example, the reflector 82 is rotated in conjunction with the third lens frame 65 that moves according to the focal length of the photographing unit 60 at the time of photographing. You may comprise so that an irradiation angle may be adjusted according to the focal distance of the imaging | photography part 60 at the time of imaging | photography. In this way, the drive source for the strobe motor 86 is not required, the structure is simplified, the entire mobile phone can be made more compact, and the cost can be reduced.

(Embodiment 4)
Next, a fourth embodiment in which the present invention is applied to a mobile phone will be described with reference to FIGS. In this case, the same parts as those in the third embodiment shown in FIGS.
As shown in FIG. 25 and FIG. 26, this mobile phone is provided with one strobe unit 105 in the second case 2 exposed by the photographing unit 60 among the first and second cases 1 and 2. The light emission adjustment mechanism 106 that varies the radiation range of the light according to the focal length at the time of photographing by the photographing unit 60 is provided, and the structure other than this is substantially the same as that of the third embodiment.

  That is, as shown in FIG. 26, the strobe unit 105 includes a light emitting element 81 and a reflector 82. The reflector 82 is formed in a parabolic or elliptical curved surface, and the light emitting element 81 is a reflector with respect to the focal position of the reflector 82. It is comprised so that it may move along the optical axis 82a of 82. The light irradiation adjusting mechanism 106 drives the strobe motor 107 based on the measurement result of the distance to the subject measured by the distance measuring unit 93, rotates the driving gear 108 by the strobe motor 107, and emits light by the driving gear 108. By moving the rack 109 provided with the element 81, the light emitting element 81 is moved along the optical axis 82a of the reflector 82 in the contact / separation direction with respect to the focal position, and the light irradiation range by the reflector 82 is photographed at the time of photographing. It is configured to adjust according to the focal length of the unit 60.

  Such a mobile phone also has substantially the same effect as the third embodiment. That is, in this mobile phone, the strobe unit 105 includes the light emitting element 81 and the reflector 82, and the light irradiation adjusting mechanism 106 changes the light emitting element 81 of the strobe unit 105 to the reflector 82 according to the focal length of the image capturing unit 60 at the time of shooting. By moving along the optical axis 82a with respect to the focal position, the flash unit 105 emits light when shooting a subject with a long focal length or when shooting a subject with a short focal length. Therefore, it is possible to irradiate the subject with light efficiently and efficiently, so that the subject itself can be illuminated brightly, and the subject can be clearly photographed even in a dark place.

  For example, when photographing a far object with a long focal distance, the light irradiation adjusting mechanism 106 moves the light emitting element 81 so as to approach the focal position of the reflector 82 as shown in FIG. The light reflected by the light can be made substantially parallel to the optical axis 82a of the reflector 82, so that the light from the light emitting element 81 can be focused and irradiated toward the subject. Further, when photographing a near subject with a short focal distance, the light irradiation adjusting mechanism 106 moves the light emitting element 81 away from the focal position of the reflector 82 as shown in FIG. The light reflected by the light can be diffused and radiated to the optical axis 82a of the reflector 82, whereby the light of the light emitting element 81 can be diffused and irradiated toward the subject. For this reason, this mobile phone can also illuminate the subject itself brightly as in the third embodiment.

  In the fourth embodiment, the light irradiation adjusting mechanism 106 drives the strobe motor 107 based on the measurement result measured by the distance measuring unit 93, and rotates the drive gear 108 by the strobe motor 107. By moving the rack 109 provided with the light emitting element 81 in 108, the light emitting element 81 is moved along the optical axis 82a of the reflector 82 in the contact / separation direction with respect to the focal position, so that the light irradiation range by the reflector 82 is increased. Although the case where it is configured to adjust according to the focal length of the photographing unit 60 at the time of photographing has been described, the present invention is not limited thereto, and for example, the third lens frame 65 that moves according to the focal length of the photographing unit 60 at the time of photographing. By moving the light-emitting element 81 in conjunction with each other, the light irradiation range by the reflector 82 is set to the value of the photographing unit 60 at the time of photographing. It may be configured to adjust in accordance with the point distance. In this way, the drive source of the strobe motor 107 is not required, the structure is simplified, the entire mobile phone can be made compact, and the cost can be reduced.

(Embodiment 5)
Next, with reference to FIGS. 28 and 29, a fifth embodiment in which the present invention is applied to a mobile phone will be described. Also in this case, the same portions as those in the third embodiment shown in FIGS.
As shown in FIGS. 29 (a) and 29 (b), this mobile phone is provided on both sides of the photographing unit 60 in the second case 2 exposed by the photographing unit 60, among the first and second cases 1 and 2. The first and second strobe units 61 and 62 are provided, respectively, and the light irradiation directions of the first and second strobe units 61 and 62 are changed according to the telephoto state and the wide-angle state of the photographing unit 60 at the time of photographing. The structure including the irradiation adjusting mechanism 110 is substantially the same as that of the third embodiment except for the above. Also in this case, the first and second strobe units 61 and 62 include the light emitting element 81 and the reflector 82 as in the third embodiment.

  That is, as shown in FIGS. 20 and 21, each reflector 82 of the first and second strobe units 61 and 62 is provided with a support shaft 83 on the outer surface corresponding to the focal position on the optical axis 82a. A support shaft 83 is rotatably supported by a support member 84, and is configured to rotate in the left-right direction on the back surface of the second case 2 around the support shaft 83 to change the light emission direction. Similarly to the third embodiment, the light irradiation adjusting mechanism 110 has a structure in which the strobe motor 86 is rotated according to the telephoto state and the wide-angle state of the photographing unit 60 at the time of photographing. By rotating the driven gear 88 with the drive gear 87 and rotating the reflector 82 about the support shaft 83 of the reflector 82, the light irradiation angle by the reflector 82 is adjusted. .

  As shown in the operation flow of FIG. 28, the photographing process in such a cellular phone is performed when the power switch is turned on and the photographing mode is selected by the operation unit 6 (see FIG. 4). The operation unit 6 is operated to select either the telephoto state or the wide angle state (step S20). Then, it is determined whether the shutter switch 9 has been half-pressed (step S21). If the shutter switch 9 has not been half-pressed, the process returns to step S20 to maintain the photographing standby state. When the shutter switch 9 is pressed halfway, the distance measuring unit 93 of the photographing unit 60 measures the distance to the subject (step S22). Based on the measurement result of the distance measuring unit 93, the electromagnetic coil unit 77 in the zoom mechanism unit 70 of the photographing unit 60 is driven by the zoom driving circuit 92, and the first and second lenses 66 and 67 are set to the telephoto state or the wide angle state. At the same time, the third lens 68 is moved to adjust the focal length (step S23).

  When the first and second lenses 66 and 67 are set to the telephoto state or the wide-angle state and the focal length is adjusted by the third lens 68, the first and second strobe units 61, The direction of light emission by each of the reflectors 62 is adjusted (step S24). That is, when the first and second lenses 66 and 67 are set to the telephoto state or the wide-angle state, the light irradiation adjusting mechanism 110 is operated according to the telephoto state or the wide-angle state of the photographing unit 60. Each reflector 82 of 62 is rotated around its support shaft 83, thereby adjusting the crossing angle of the optical axis 82 a of each reflector 82 with respect to the optical axis 4 a of the photographing unit 60.

  For example, when the subject is photographed in the telephoto state, as shown in FIG. 29A, the rotation angle of the reflector 82 is set so that the intersection angle of the optical axis 82a of the reflector 82 with respect to the optical axis 4a of the photographing unit 60 becomes small. Thus, the light emitted from the first and second strobe units 61 and 62 is concentrated toward the subject. When the subject is photographed in the wide-angle state, as shown in FIG. 29B, the rotation angle of the reflector 82 is set so that the intersection angle of the optical axis 82a of the reflector 82 with respect to the optical axis 4a of the photographing unit 60 becomes large. Thus, the light emitted from the first and second strobe units 61 and 62 is concentrated toward the subject so as to intersect. When the shutter switch 9 is fully pushed in such a state, the first and second strobe units 61 and 62 emit light, and the light is concentrated and irradiated toward the subject by the reflectors 82. The image of the irradiated subject is captured as image data by the image sensor 74, and this flow is finished.

  Thus, this mobile phone also has substantially the same operational effects as the third embodiment. That is, in this mobile phone, when the subject is photographed by the photographing unit 60, the light irradiation adjusting mechanism 110 performs light irradiation by the first and second strobe units 61 and 62 according to the telephoto state and the wide-angle state of the photographing unit 60. By adjusting the radiation direction, the light of the first and second flash units 61 and 62 is concentrated toward the subject when photographing the subject in the telephoto state and when photographing the subject in the wide-angle state. Can be irradiated. For this reason, the light emitted from the first and second strobe units 61 and 62 can be efficiently directed toward the subject in both the telephoto state and the wide-angle state, thereby illuminating the subject itself brightly. The subject can be photographed clearly even in a dark place.

  In this case, the first and second strobe units 61 and 62 include two sets of the light emitting element 81 and the reflector 82, and the light irradiation adjusting mechanism 110 has two sets according to the telephoto state and the wide-angle state of the photographing unit 60 during photographing. Since the light irradiation angle of each of the reflectors 82 is varied, for example, when the subject is photographed in the telephoto state, the reflector 82 is configured so that the intersection angle of the optical axis 82a of the reflector 82 with respect to the optical axis 4a of the photographing unit 60 becomes small. When the subject is photographed in a wide-angle state, the rotation angle of the reflector 82 is increased so that the crossing angle of the optical axis 82a of the reflector 82 with respect to the optical axis 4a of the photographing unit 60 increases. As a result, the light emitted from the first and second strobe units 61 and 62 can be reliably focused toward the subject in both the telephoto state and the wide-angle state. , It is therefore possible to brightly and uniformly illuminate an object.

  In the fifth embodiment, the light irradiation adjusting mechanism 110 is configured to vary the light irradiation angle by the two sets of reflectors 82 according to the telephoto state and the wide-angle state of the photographing unit 60 at the time of photographing. As described above, the present invention is not limited to this. For example, as in the fourth embodiment shown in FIGS. The light irradiation adjustment mechanism 110 may be configured to vary depending on the telephoto state and the wide-angle state of the imaging unit 60.

  Also in this case, the strobe unit 105 is configured such that the light emitting element 81 moves along the optical axis 82 a of the reflector 82 with respect to the focal position of the reflector 82. Further, the light irradiation adjusting mechanism 110 drives the strobe motor 107 based on the telephoto state and the wide-angle state of the photographing unit 60 at the time of photographing, and rotates the driving gear 108 of the strobe motor 107. By moving the rack 109 provided with the light emitting element 81, the light emitting element 81 is moved along the optical axis 82a of the reflector 82 in the contact / separation direction with respect to the focal position, and the light irradiation range by the reflector 82 is taken at the time of photographing. What is necessary is just to comprise so that it may adjust according to the telephoto state and wide-angle state of the imaging | photography part 60 in FIG.

  Also in such a cellular phone, the strobe unit 105 includes the light emitting element 81 and the reflector 82, and the light irradiation adjusting mechanism 110 emits light from the strobe unit 105 according to the telephoto state and the wide angle state of the photographing unit 60 during photographing. 81 can be moved along the optical axis 82 a with respect to the focal position of the reflector 82. For example, when photographing a subject in a telephoto state, the light irradiation adjusting mechanism 110 moves the light emitting element 81 so as to approach the focal position of the reflector 82, so that the reflector 82 emits light substantially parallel to the optical axis 82a. As a result, the light of the light emitting element 81 can be concentrated and directed toward the subject.

  When photographing a subject in a wide-angle state, the light irradiation adjusting mechanism 110 moves the light emitting element 81 away from the focal position of the reflector 82, so that the reflector 82 diffuses and emits light to the optical axis 82a, Thereby, the light of the light emitting element 81 can be diffused and irradiated toward the subject. For this reason, even in this mobile phone, the light irradiation adjusting mechanism 110 can respond to the telephoto state and the wide-angle state of the photographing unit 60 at the time of photographing regardless of whether the photographing state at the time of photographing is the telephoto state or the wide-angle state. Thus, the light from the flash unit 105 can be reliably irradiated toward the subject. As a result, the subject itself can be illuminated brightly as in the third and fourth embodiments, so that the subject can be clearly photographed even in a dark place. Can do.

  In the first to fifth embodiments, the light sensor unit 39 including the light emitting element 40 and the plurality of light receiving elements 41a to 41c is used as a detecting unit that detects the relative rotation angle of the first and second cases 1 and 2. However, the present invention is not limited to this. For example, the rotary shaft 3 may be provided with an encoder that detects the relative rotation angle of the first and second cases 1 and 2.

  That is, as shown in FIG. 30, the first shaft portion 123 has a large-diameter head portion 123a formed in the upper portion thereof, a small-diameter cylindrical portion 123b formed in the lower portion thereof, and the large-diameter head portion 123a formed in the second portion. In a state of protruding upward from the case 2, a small-diameter cylindrical portion 123 b is rotatably attached to one end portion (the right end portion in FIG. 30) of the second case 2 so as to penetrate vertically. In this case, the head portion 123a of the first shaft portion 123 is configured to be disposed in a semicircular cutout recess 125 formed in one end portion (left end portion in FIG. 30) of the first case 1. . Further, as shown in FIG. 30, the second shaft portion 124 is formed on the outer peripheral portion of the head portion 123a of the first shaft portion 123 so as to protrude on both sides in the direction orthogonal to the central axis of the first shaft portion 123. The first case 1 is rotatably inserted into a support hole 126 provided facing the inner peripheral surface of the notch recess 125 of the first case 1, and in this state, the first case 1 is vertically moved around the second shaft portion 124. It is comprised so that it may rotate.

  As a result, the connecting shaft 120 has the first and second cases 1 and 2 relatively rotated along their opposing surfaces as shown in FIG. 33, and the first case 1 as shown in FIG. In addition to rotating in a direction to stand up with respect to the second case 2, the second case 2 is configured to rotate while the first case 1 stands up with respect to the second case 2 as shown in FIG. That is, as shown in FIG. 33, when opening the first and second cases 1 and 2, the first and second cases 1 and 2 are arranged on the surface of the cylindrical portion 123 b of the first shaft portion 123 of the connecting shaft 120. Rotate in the direction. As shown in FIG. 34, when the first and second cases 1 and 2 are opened, the first case 1 stands up with respect to the second case 2 around the second shaft portion 124 of the connecting shaft 120. Rotate toward Furthermore, as shown in FIG. 35, when the first case 1 is rotated while standing on the second case 2, the first case 1 is centered on the cylindrical portion 123 b of the first shaft portion 123 and the second case 2.

  Thereby, the first and second cases 1 and 2 are overlapped with the display unit 5 of the first case 1 and the key input unit 7 of the second case 2 facing each other as shown in FIG. 31 and FIG. As shown in FIGS. 36 and 37, the first and second cases 1 and 2 are configured to overlap each other with the display unit 5 of the first case 1 exposed to the outside. The first and second cases 1 and 2 are electrically connected by a connecting member (not shown) via the connecting shaft 120.

  On the other hand, the photographing unit 121 has a telephoto function as a zoom function, and as shown in FIG. 38, the photographing direction is set to the back side of the second case 2, that is, the input surface of the key input unit 7 of the second case 2. Is provided in the cylindrical portion 123b of the first shaft portion 123 of the connecting shaft 120 so as to be zoomable along the axial direction. The photographing unit 121 is configured in substantially the same manner as the photographing unit 4 of the first embodiment. That is, as shown in FIG. 38, the photographing unit 121 includes a cylindrical lens barrel 11 that is concentrically fixed in a cylindrical portion 123b of the first shaft portion 123.

  Inside the lens barrel 11 are first and second lens frames 12 and 13 movably arranged along the axial direction thereof, and first and second lens frames 12 and 13 attached to the first and second lens frames 12 and 13, respectively. 1, the first lenses 14 and 15 are disposed on the optical axis in the axial direction of the first shaft portion 123 in the cylindrical portion 123b of the first shaft portion 123 via the crystal filter 16a and the protective glass 16b. An image sensor 17 such as a CCD is provided that converts the image of the subject projected by the second lenses 14 and 15 into an electrical signal and outputs the electrical signal. In addition, on the outer peripheral portion of the lens barrel 11, a zoom that moves the first and second lens frames 12 and 13 of the first and second lenses 14 and 15 along the axial direction of the first shaft portion 123 that is an optical axis. A mechanism unit 18 is provided.

  That is, as shown in FIG. 38, a slit-shaped guide hole 11a penetrating from the outer surface to the inner surface is provided on the outer peripheral surface of the lens barrel 11 along the axial direction of the first shaft portion 123. The second lens frames 12 and 13 are inserted into the guide hole 11a of the lens barrel 11, protruded toward the outer peripheral surface of the lens barrel 11, and moved along the guide hole 11a in this state. 12a and 13a are provided. As a result, the first and second lens frames 12 and 13 move together with the first and second lenses 14 and 15 along the axial direction of the first shaft portion 123 without rotating in the lens barrel 11. It is configured.

  The zoom mechanism unit 18 includes a rotary cylinder 19 that is rotatably provided on the outer peripheral surface of the lens barrel 11 in the first shaft portion 123, and a zoom motor 20 that rotates the rotary cylinder 19. . The rotating cylinder 19 is rotatably attached to a predetermined position on the outer peripheral surface of the lens barrel 11 without moving in the axial direction, and the inner surface of the rotating cylinder 19 is similar to the first embodiment. 1 and 2nd spiral grooves 19a and 19b are provided. The first protrusion 12a of the first lens frame 12 is inserted into the first spiral groove 19a through the guide hole 11a of the lens barrel 11. The second spiral groove 19b has a second projection of the second lens frame 13. The protrusion 13 a is inserted through the guide hole 11 a of the lens barrel 11.

  In addition, a driven gear 21 is provided on the outer peripheral surface of the rotary cylinder 19 as shown in FIG. The motor 20 is fixed in the second case 2 positioned in the vicinity of the first shaft portion 123, and a drive gear 22 is provided on the output shaft via an electromagnetic clutch 127. The rotation of the motor 20 is transmitted to the rotating cylinder 19 by meshing with the gear 21 and rotating. In this case, when the electromagnetic clutch 127 is in a normal state in which no power is supplied, the motor clutch rotates idly and rotation of the motor 20 is not transmitted to the drive gear 22, and in the first state in which the shutter switch 9 is half-pressed, the electromagnetic clutch 127 is energized. The rotation of 20 is transmitted to the drive gear 22, so that when the second case 2 rotates relative to the first shaft portion 123 of the connecting shaft 120, the rotation is not transmitted to the motor 20.

  Accordingly, in the zoom mechanism 18, when the shutter switch 9 is half-pressed and the electromagnetic clutch 127 is energized, and the motor 20 rotates in this state, the rotation is transmitted to the drive gear 22 via the electromagnetic clutch 127. The rotation of the drive gear 22 is transmitted to the rotary cylinder 19 by the driven gear 21, whereby the rotary cylinder 19 is rotated, and the first and second spiral grooves 19a and 19b of the rotary cylinder 19 are rotationally moved along with the rotation. At this time, the first and second projecting portions 12a and 13a of the first and second lens frames 12 and 13 are placed at locations where the first and second spiral grooves 19a and 19b intersect with the guide hole 11a of the lens barrel 11. The first and second spiral grooves 19a and 19b of the rotating cylinder 19 are moved along the guide hole 11a of the lens barrel 11, whereby the first and second lens frames 12 and 13 are moved to the first and second lenses 14 and 15, respectively. At the same time, it is moved along the axial direction of the first shaft portion 123.

  In this case, when the motor 20 rotates in the forward direction and the rotating cylinder 19 rotates in the direction of the arrow X shown in FIG. The first lens is moved while the second spiral groove 19b moves the second lens frame 13 from the first shaft portion 123 toward the outside (left side in FIG. 7). It is configured to approach the frame 12 and thereby bring the photographing range into the telephoto state. In addition, when the motor 20 rotates reversely and the rotating cylinder 19 rotates in the direction opposite to the arrow X direction shown in FIG. The first and second lenses 14 and 15 are configured to be stored inside the first shaft portion 123.

  According to such a cellular phone, as in the first and third embodiments, the first case 1 having the display unit 5 and the second case 2 having the key input unit 7 are opened and closed by the connecting shaft 120 having the photographing unit 121 built-in. Since the first and second cases 1 and 2 are opened, the display surface of the display unit 5 and the input surface of the key input unit 7 can be directed in the same direction. The photographing direction can be directed in the opposite direction with respect to the display surface and the input surface. Thereby, the display surface of the display unit 5 can be directed in the direction opposite to the shooting direction of the shooting unit 121 with a simple operation by simply opening the first and second cases 1 and 2. For this reason, when taking a picture, it is possible to take a picture while viewing the image of the subject displayed on the display unit 5, and since the photographing unit 121 includes the zoom mechanism unit 18, the image is displayed on the display unit 5. It is possible to adjust the shooting range of the subject while viewing the image of the subject so that a subject image having a desired size can be obtained satisfactorily.

  In this case, in particular, as shown in FIG. 30, the connecting shaft 120 is configured so that the opposing surfaces of the first case 1 and the second case 2, that is, the display surface of the display unit 5 of the first case 1 and the key input of the second case 2. A hollow first shaft portion 123 provided in a direction perpendicular to both the input surface of the portion 7 and a rod-shaped second shaft portion 124 provided orthogonal to the first shaft portion 123. The cylindrical portion 123b of the first shaft portion 123 is rotatably attached to the second case 2 except for the head portion 123a of the first shaft portion 123 provided with the second shaft portion 124, and is attached to the second shaft portion. Since the 1st case 1 is attached so that rotation is possible, when opening the 1st and 2nd cases 1 and 2, the 1st, 2nd centering on the cylinder part 123b of the 1st axial part 123 of the connection shaft 120 is demonstrated. When rotated in the surface direction of the cases 1 and 2, as shown in FIG. It can be opened.

  Further, at this time, when the first case 1 is rotated upward with respect to the second case 2 around the second shaft portion 124 of the connecting shaft 120, as shown in FIG. 1 can be opened up on the second case 2. In this state, when the first case 1 is rotated with respect to the second case 2 around the cylindrical portion 123b of the first shaft portion 123 of the connecting shaft 120, the key input of the second case 2 is performed as shown in FIG. The orientation of the display surface of the display unit 5 of the first case 1 with respect to the input surface of the unit 7 can be changed. For example, when the first and second cases 1 and 2 are opened, as shown in FIG. 33, the display surface of the display unit 5 of the first case 1 and the input surface of the key input unit 7 of the second case 2 are the same. The display surface of the display unit 5 of the first case 1 and the input surface of the key input unit 7 of the second case 2 can be directed in opposite directions.

  As a result, even when the first and second cases 1 and 2 are overlapped and closed, as shown in FIGS. 31 and 32, the display surface of the display unit 5 of the first case 1 and the key of the second case 2 are displayed. The input surface of the input unit 7 faces each other and can be directed in opposite directions. As shown in FIGS. 36 and 37, the display surface of the display unit 5 of the first case 1 and the key input of the second case 2 The input surface of the unit 7 can be directed in the same direction. Thereby, the direction of the display unit 5 of the first case 1 with respect to the key input unit 7 of the second case 2 can be freely selected.

  In this case, when the display unit 5 of the first case 1 and the key input unit 7 of the second case 2 face each other and overlap each other as in the former case, the display unit 5 of the first case 1 and the second case 2 Since the key input unit 7 is not exposed to the outside, the display unit 5 and the key input unit 7 can be protected by the first and second cases 1 and 2, and thus can be safely and satisfactorily carried. Further, when the display surface of the display unit 5 of the first case 1 and the input surface of the key input unit 7 of the second case 2 overlap in the same direction as in the latter case, the first case 1 is placed on the second case 2. Since case 1 overlaps, display part 5 of the 1st case 1 will always be exposed. For this reason, even when the first and second cases 1 and 2 are overlapped and closed, the information displayed on the display unit 5 can be freely viewed at any time.

  Further, when the subject is photographed with this mobile phone, if the display surface of the display unit 5 of the first case 1 and the input surface of the key input unit 7 of the second case 2 are directed in the same direction, the opposite direction to this will be described. Since the photographing direction of the photographing unit 121 can be directed to the first, the first and second cases 1 and 2 are opened as shown in FIG. 33, and as shown in FIGS. Even in a state where the second cases 1 and 2 are overlapped and closed, an image of the subject can be displayed on the display unit 5 and the image can be taken by the photographing unit 121 while viewing the displayed image of the subject. At this time, since the photographing unit 121 includes the zoom mechanism unit 18, the photographing range of the subject can be adjusted while viewing the subject image displayed on the display unit 5. Can be obtained satisfactorily.

  Also in this case, the photographing unit 121 is provided in the cylindrical portion 123b of the first shaft portion 123 of the connecting shaft 120 so as to be zoomable along the axial direction. The display unit 5 of the first case 1 and the key input unit 7 of the second case 2 are not restricted by the photographing unit 121, and the installation areas of the display unit 5 and the key input unit 7 are defined in the first, second case 1, 2 can be sufficiently secured. Further, since the shutter switch 9 is provided on the side surface of the second case 2, the shutter switch 9 does not restrict the display unit 5 or the key input unit 7. A sufficient installation area can be secured.

  In particular, the shutter switch 9 is provided on the side surface of the second case 2 so that the first and second cases 1 and 2 can be connected to each other even when the first and second cases 1 and 2 are overlapped and closed. Even in the opened state, the shutter switch 9 is always exposed to the outside, so that the shutter switch 9 can be operated easily and satisfactorily. In this case, since the shutter switch 9 is provided on the side surface of the second case 2 located in the vicinity of the connecting shaft 120, the first and second cases are closed in a state where the first and second cases 1 and 2 are closed. Even if you hold the case 1 or 2 with both hands, or you hold the second case 2 with one hand while the first and second cases 1 and 2 are open to each other, the finger of the hand naturally contacts the shutter switch 9 Therefore, the shutter switch 9 can be operated satisfactorily and reliably at the time of photographing.

  The shutter switch 9 operates the zoom mechanism 18 of the photographing unit 121 when it is half-pressed, and captures an image of the subject with the photographing unit 121 when the shutter switch 9 is fully depressed. In this state, the zoom mechanism 18 of the photographing unit 121 can be operated to adjust the photographing range of the subject to set the angle of the subject. When the shutter switch 9 is fully pushed in this state, the photographing unit Since the image of the subject is captured at 121, the image of the subject can be captured well at a desired angle.

  In the sixth embodiment, the zoom mechanism unit 18 of the photographing unit 121 transmits the rotation of the motor 20 to the rotating cylinder 19 by the driving gear 22 and the driven gear 21, and the rotating cylinder 19 is rotated along with the rotation of the rotating cylinder 19. The first and second lens grooves 12 and 13 are moved in the axial direction of the first shaft portion 123 together with the first and second lenses 14 and 15 by the first and second spiral grooves 19a and 19b provided in the first and second spiral grooves 19a and 19b. Although the case where it comprised was described, it is not restricted to this, For example, similarly to Embodiment 3-5, the several 1st-3rd lens frames 63-65 are moved by moving the several permanent magnets 78-80 with the electromagnetic coil part 77, for example. The zoom mechanism unit 70 may be used to move the lens together with the first to third lenses 66 to 68.

  By using the zoom mechanism unit 70 having such a configuration, the photographing unit 121 can be configured more compactly than the structure of mechanically moving the zoom mechanism unit, and the zoom mechanism of the photographing unit 121 can be configured. Since the unit 70 is zoomed by a magnetic force, there are few mechanical parts, the structure is simple, the impact resistance when carrying is high, and the failure due to the impact is reduced compared to the structure in which the photographing part mechanically operates. be able to.

  Also in the sixth embodiment, as the detection means for detecting the relative rotation angle of the first and second cases 1 and 2, for example, the rotation of the first and second cases with respect to the first shaft portion 123 of the connecting shaft 120. Detection means such as an encoder for detecting an angle is provided, and the display form of the display unit 5 is controlled based on the detection result detected by the detection means, so that the first and second cases 1 and 2 can be opened. Thus, the display state of the display unit 5 may be automatically changed to vertical display or horizontal display. In this way, as in the first to fifth embodiments, even if the opening angle of the first and second cases 1 and 2 changes, the information displayed on the display unit 5 can be easily viewed.

  Also in the sixth embodiment, as in the third to fifth embodiments, a flash unit that emits a flash, for example, the first and second flash units 61 and 62, or the flash unit 105 is provided in the vicinity of the photographing unit 121. The flash unit may be configured to irradiate the subject with light, and the light irradiation adjustment mechanism 85, 106, 110 may adjust the light irradiation state on the subject to an optimum state. Also good.

  In this case, by providing a light irradiation adjustment mechanism that varies the radiation direction of the light emitted from the flash unit or the radiation range of the light according to the focal length of the photographing unit at the time of photographing, When shooting an image of a subject with a short focal length, the light emission adjustment mechanism can adjust the radiation direction of the light emitted by the flash unit or the light emission range. This makes it possible to irradiate the flash part light efficiently and reliably toward the subject, so when shooting a long subject with a long focal length, even when shooting a close subject with a short focal length, The subject can be illuminated brightly.

  In addition, the flash unit includes a plurality of sets of light emitting elements and reflectors, and the light irradiation adjusting mechanism varies the irradiation angle by each of the plurality of sets of reflectors according to the focal length of the imaging unit at the time of shooting, for example, a long focal length. When shooting a distant subject, reduce the reflector rotation angle so that the crossing angle of the optical axis of the reflector with respect to the optical axis of the shooting unit is small, and when shooting a close subject with a short focal length, The reflector rotation angle is increased so that the crossing angle of the optical axis of the reflector with respect to the optical axis increases, so that the light from the flash part is focused toward the subject regardless of whether the focal length is long or short. Therefore, the subject can be illuminated brightly.

  In addition, the flash unit is composed of a light emitting element and a reflector, and the light irradiation adjusting mechanism varies the light emitting element with respect to the focal position of the reflector according to the focal length of the photographing unit at the time of photographing, for example, a long focal distance. When photographing a subject, the light irradiation adjustment mechanism moves the light emitting element so as to be close to the focal position of the reflector so that the light emitted by the reflector is substantially parallel to the optical axis of the reflector. When shooting a near subject with a short focal length, the light irradiation adjusting mechanism moves the light emitting element away from the focal position of the reflector and emits it by the reflector. The light is diffused and radiated to the optical axis of the reflector, so that the light from the light emitting element is diffused toward the subject and irradiated. Bets can be, even if this reason shorter and longer focal length can be brightly illuminated object.

  In addition, it is equipped with a light irradiation adjustment mechanism that varies the radiation direction of the light emitted by the flash unit or the radiation range of the light according to the telephoto state and wide-angle state of the photographing unit at the time of photographing. When shooting a subject or shooting a subject in a wide-angle state, the light emission direction or the light emission range can be adjusted by the light irradiation adjustment mechanism. This ensures that the subject's light is efficiently directed toward the subject, so that the subject can be illuminated brightly both when shooting the subject in the telephoto state and when shooting the subject in the wide-angle state. .

  Further, the flash unit includes a plurality of sets of light emitting elements and reflectors, and the light irradiation adjustment mechanism varies the irradiation angle by each of the plurality of sets of reflectors according to the telephoto state and the wide angle state of the imaging unit at the time of shooting, for example, When shooting a subject in the telephoto state, reduce the reflector rotation angle so that the crossing angle of the optical axis of the reflector with respect to the optical axis of the shooting unit is small, and when shooting the subject in a wide angle state, The reflector's rotation angle is increased so that the crossing angle of the reflector's optical axis with respect to the optical axis is increased. This makes it possible to focus and irradiate the flash light toward the subject in both the telephoto and wide-angle states. Therefore, the subject can be illuminated brightly.

  Further, the flash unit is composed of a light emitting element and a reflector, and the light irradiation adjusting mechanism changes the light emitting element with respect to the focal position of the reflector according to the telephoto state and wide angle state of the photographing unit at the time of photographing, for example, in the telephoto state. When shooting a subject, the light irradiation adjustment mechanism moves the light emitting element closer to the focal position of the reflector so that the light radiated by the reflector is substantially parallel to the optical axis of the reflector. When shooting a subject in a wide-angle state, the light irradiation adjustment mechanism moves the light emitting element away from the focal position of the reflector so that the light emitted by the reflector can be emitted. Diffuse radiation is applied to the optical axis of the reflector so that the light emitted from the light emitting element can be diffused toward the subject for irradiation. Can, even in the wide-angle state in this order telephoto state, it is possible to illuminate brightly the subject.
