DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the electronic device with a photographing function of the present invention is applied to a portable telephone will be described below with reference to the accompanying drawings.

{1. FIG. 1 is a perspective view of a mobile phone 1 according to the present embodiment. The mobile phone 1 includes a main body 10 having various functions of the mobile phone, and a camera unit 20 rotatably attached to the main body 10. Here, the front direction with respect to the operation surface 1S of the mobile phone 1 is indicated by an arrow 1F in the figure. In addition, the rear direction from the back side surface of the operation surface 1S is
1B, and the upward direction of the mobile phone 1 is indicated by an arrow 1U.

A monitor 11 for displaying various information such as a telephone number display and an operation menu display is provided on the operation surface 1S of the mobile phone 1. In the present embodiment, the monitor 11
Employs a liquid crystal display device.

At the lower side of the monitor 11, a cursor 12a
And a plurality of button keys 12b. these,
Using the cursor 12a and the button keys 12b, various functions of the mobile phone 1 can be operated, and dialing operation can be performed. In the following description, the cursor 12a and the button keys 12b are collectively referred to as the operation unit 12.

An antenna 13 is provided on the upper part of the main body 10. The figure shows a state in which the antenna 13 is housed in the main body 10. The antenna 13 is pulled out and used in the upward direction 1U during communication.

The mobile phone 1 according to the present embodiment
The camera unit 20 is provided at one end of the upper part of the main body 10. The camera unit 20 is mounted so as to be rotatable in the vertical direction of the mobile phone 1 around a central axis 20c indicated by a virtual line in the figure. In FIG. 1, the camera unit 20 is rotated downward. The state is shown. Also,
FIGS. 2 and 3 show an entrance 21 as an entrance when a subject image enters the optical system in the camera unit 20. That is, FIG. 1 shows a state in which the incident portion 21 is housed on the engagement surface with the main body 10.

FIG. 2 shows the operation of the camera unit 20 on the operation surface 1S.
The state which turned to the side is shown. That is, FIG. 2 shows a state in which a subject in the front direction 1F of the mobile phone 1 can be photographed.

FIG. 3 shows the camera unit 20 connected to the mobile phone 1.
The upper part of FIG.
The subject of U can be photographed.

FIG. 4 shows a state in which the camera unit 20 has been turned to the opposite side of the operation surface (the back side of the operation surface 1S).
That is, FIG. 4 shows a state in which a subject in the rear direction 1B of the mobile phone 1 can be photographed.

As described above, the camera unit 20 is rotatably mounted on the operation surface 1S side, the upward direction 1U, the opposite operation surface side of the mobile phone 1, and between the retracted state shown in FIG. Thus, the user performs the shooting operation after rotating the camera unit 20 in a desired direction according to the content of the subject and the shooting situation.

The photographing operation can be performed by using the operation unit 12 provided on the mobile phone 1. That is, all operations related to photographing, such as a shutter instruction operation and various photographing mode setting operations, are performed by the operation unit 12. An operation command instructed by the operation unit 12 is transmitted to the camera unit 20 via a data line (not shown) provided between the main body 10 and the camera unit 20, and a lens mechanism, a shutter mechanism, and the like in the camera unit 20 are provided. Control, image processing control, and the like.

The camera unit 20 has a zoom adjustment function. The zoom adjustment function according to the present embodiment is configured to reduce the complexity of manual zoom adjustment operation. The configuration of the zoom adjustment function will be described later.

Image data photographed by the camera unit 20 is transmitted to the main unit 10 via an image data line (not shown) provided between the main unit 10 and the camera unit 20. The photographed image is displayed on the monitor 11. The monitor 11 also plays a role as a view finder, and a user can check in real time image information output from a CCD 230 (illustrated in FIG. 5 and the like) which is an image sensor in the camera unit 20. It is possible. Therefore, the user can check the composition of the photographing and adjust the zoom while referring to the monitor 11.

{2. Relationship Between Shooting Direction and Zoom Ratio {Here, the relationship between the shooting direction of the camera unit 20 and the zoom ratio will be described. In the case of a general camera, since the shooting direction is fixed with respect to the camera body, there is no correlation between the shooting direction and the zoom magnification. Therefore, the zoom magnification depends on the operation of the user. But,
As shown in the present embodiment, when a small camera is rotatably attached to mobile phone 1, there is a correlation between the shooting direction and the zoom magnification.

FIG. 2 shows a case where the camera unit 20 is rotated toward the operation surface 1S. In this case, the incident portion 21 of the camera unit 20 and the operation surface 1S face in the same direction. That is, a user who refers to the monitor 11 or operates the operation unit 12 (a person who operates a mobile phone)
Since the camera is directed to the side, it is often the situation that the user himself is photographed.

For example, it is assumed that a photograph of oneself is taken. If the mobile phone 1 functions as a videophone, a case where the photographed image is transmitted to the other party while photographing his / her own image is assumed.

As described above, when photographing oneself, since the distance from the camera unit 20 (incident part 21) to the subject is short, it is necessary to reduce the magnification of the subject in the zoom adjustment. That is, it is desirable to reduce the zoom magnification to perform wide-angle shooting.

FIG. 3 shows a case where the camera unit 20 is rotated upward 1U. In this case, mobile phone 1
It is convenient when the macro shooting (close-up shooting) is performed by bringing the subject closer to the upper end side (front end side) of the camera. When performing macro shooting, since the target is a subject with a relatively small shape,
As shown in FIG. 12, the front end side of the mobile phone 1, that is, the incident part 21 of the camera unit 20 is brought closer to the subject. This makes it easy to check the shooting state of the subject while looking into the monitor 11 from above, which is convenient for shooting at a low angle. Also, the antenna 13
If you use a strap or a strap, you can use it as a guide for the shooting distance in macro shooting.

FIG. 4 shows a case where the camera unit 20 is turned to the side opposite to the operation surface. In this case, the incident portion 21 of the camera unit 20 and the operation surface 1S face in opposite directions. That is, since the incident unit 21 faces the opposite side of the user (the person who operates the mobile phone) who operates the monitor 11 and the operation unit 12, it is possible to photograph another person, This is suitable for shooting a relatively distant subject, such as when shooting a subject.

As described above, when photographing another person, landscape, or the like, since the distance from the incident portion 21 to the subject is long, the zoom adjustment needs to increase the subject magnification. In other words, it is desirable to increase the zoom magnification for shooting.

{3. Configuration of Camera Unit｝ <3-1 Basic Configuration> Next, the configuration of the camera unit 20 according to the present embodiment will be described. 5 and 6 show the main parts of the configuration inside the camera unit 20. FIG.

In FIG. 5, the arrow 20d indicates the direction connecting the incident part 21 and the CCD 230, and
Is a direction orthogonal to the rotation center axis 20c. As shown in FIG. 1, when the camera unit 20 is in the housed state, the arrow 20 d is substantially parallel to the upward direction 1U of the mobile phone 1.

In the camera unit 20, a lens 214, a lens 224, and a C
The CDs are arranged in this order. Therefore,
A subject image incident into the camera unit 20 from the incident unit 21 is transmitted to the CCD 230 via the zoom lens mechanism 210.
Is imaged. The electric charge accumulated in the CCD 230 is output as an electric signal, subjected to predetermined image processing (gradation conversion processing, white balance processing, and the like), and then transmitted to the main body 10 via the data image line described above. It is. In the drawings, a lens mechanism, a diaphragm mechanism, and the like for performing focus control are omitted.

Next, the zoom lens mechanism 210 will be described in detail. As shown in FIG. 5 and FIG.
Reference numerals 1 and 221 denote substantially rectangular parallelepiped members, each having a lens 214,
224.

At one end of an upper part of the lens frame 211 (hereinafter, in the description with reference to FIG. 6, the arrow A in the drawing is assumed to be the upper part of the zoom lens mechanism 210), a protrusion protruding upward is provided. Portion 211a is formed, and the protrusion 2
A guide hole 211b is formed at a substantially central position of 11a so that the guide shaft 212 can be inserted. Guide shaft 212
Is a rod-shaped member having a substantially cylindrical shape, and is slidable in the direction of arrow 20d in the substantially circular guide hole 211b.

Similarly, a protruding portion 221a protruding upward is formed on one end side of the upper portion of the lens frame 221. The guide shaft 22 is provided substantially at the center of the protruding portion 221a.
A guide hole 221b is formed so as to allow the insertion of the guide hole 221. Similarly, the guide shaft 222 is a rod-shaped member having a substantially columnar shape, and is slidable in the direction of the arrow 20d in the substantially circular guide hole 221b.

Note that, as shown in FIG.
And the protruding portion 221a are provided at left and right opposite ends.

Further, at the lower part of the lens frame bodies 211 and 221, a protruding part 2 protruding in
11c and 221c are formed, and the protrusions 211c and 221c are formed.
Guide grooves 211d and 221d are formed in the lower end 221c from the lower end to the upper end. The guide shaft 231 that is a substantially cylindrical rod-shaped member is disposed so as to pass through the two guide grooves 211d and 221d.

Here, as shown in FIG. 6, the guide grooves 211d and 221d are provided at the overlapping positions when the lens frame bodies 211 and 221 are viewed from the front side. 231 will be arrange | positioned substantially parallel to the arrow 20d direction. Similarly, the guide shaft 21
The guide shafts 212, 222, and 231 are also fixed to the case 200 side of the camera unit 20 via a support member or the like. Therefore, the lenses 214 and 224 are integrated with the lens frames 211 and 221 to form the guide shaft 212 and
While being supported by 222 and 231, they are arranged so as to be able to translate in the direction of the arrow 20 d.

A lens drive unit (not shown) for independently moving the lens frame bodies 211 and 221 in the direction of arrow 20d is provided. The lens drive unit is controlled to control the lenses 214 and 224. It changes the distance between the lenses. As a result, the focal length formed via the lenses 214 and 224 changes, and the subject magnification changes. Also, two lenses 214, 2
The movement of the focal point 24 is controlled so that the focal position does not change.

<3-2 Interlocking Structure of Camera Unit Rotation Position and Zoom Magnification> With the above configuration, zoom adjustment can be performed by changing the distance between lenses. Next, a zoom adjustment mechanism linked to the rotation position of the camera unit 20 will be described.

FIG. 6 shows a pivot point between the portable telephone body 10 and the camera unit 20. A fixed shaft 105 protrudes from the case 100 of the main body 10 toward the outside of the case, and the other end of the fixed shaft 105 extends into the unit case 200 of the camera unit 20. The unit case 200 is provided at the tip of the fixed shaft 105.
The cam plate 110 is fixed inside. Note that the fixed shaft 105 is fixed to the main body side and does not rotate.

A boss 101 of the case 100 is formed in an annular shape around the outer periphery of the fixed shaft 105, and the boss 101 passes through a bearing hole 200 a provided in the unit case 200. It extends into the unit case 200. As a result, the camera unit 20 is supported rotatably about the fixed shaft 105. This rotation center coincides with the virtual center axis 20c described above.

FIG. 7 is a plan view of the cam plate 110. FIG. Two curved cam grooves 11 are provided on one end surface of the cam plate 110.
1, 112 are formed. Then, the cam plate 110
Are arranged so that the cam grooves 111 and 112 face the zoom mechanism 210 side, as shown in FIG.

The cam groove 111 is a curved groove connecting the storage position 111A, the wide shooting position 111B, the macro shooting position 111C, and the telephoto shooting position 111D.
The distance from the center point 110c of the cam plate 110 is continuously reduced as → 111B → 111C → 111D.

The cam groove 112 is located at the storage position 112.
A, wide shooting position 112B, macro shooting position 112
C, a curved groove connecting the telephoto shooting position 112D, which is formed so that the distance from the center point 110c of the cam plate 110 increases continuously as the position progresses from 112A to 112B to 112C to 112D.

On the other hand, as shown in FIG. 5 and FIG.
13 and 223 are projected, and the engagement pins 213 and 2
23 are cam grooves 111, 112 of the cam plate 110, respectively.
Is engaged.

As described above, the lens frames 211 and 221
Is a guide shaft 21 fixed to the unit case 200 side.
2,222,231. Therefore, with the rotation of the camera unit 20, the lens frame bodies 211 and 221 also rotate integrally.

At this time, since the lens frames 211 and 212 are supported by the guide shafts 212, 222 and 231, they are always kept in a parallel state. However, the engagement pin 21 is fixed to the cam plate 110 fixed to the main body 10 side.
3, 223 are engaged, so that the lens frame 211,
The position of 21 is regulated by the curved shape of the cam grooves 111 and 112.

Here, the engaging pins 213 and 223 are arranged at the same height in the vertical direction of the lens frame bodies 211 and 221, and the cam grooves 111 and 223 of the engaging pins 213 and 223 are provided.
The engagement position with the cam plate 112 is always the center point 1 of the cam plate 110.
They will be arranged on a straight line passing through 10c.

Therefore, when the camera unit 20 is rotated with the cam plate 110 fixed, as shown in FIG. 7, the two engagement pins 213 and 223 respectively move when the camera unit 20 is stored (see FIG. 7). 1), they are located at the storage positions 111A and 112A, at the time of wide shooting (the state of FIG. 2), at the wide shooting positions 111B and 112B, and at the time of macro shooting (the state of FIG. 3). They are located at the macro shooting positions 111C and 112C, and are located at the telephoto positions 111D and 112D during telephoto shooting (the state of FIG. 4).

FIG. 8 shows the relationship between the movement positions of the lens frame bodies 211 and 221 (movement amounts in the direction of arrow 20d). The lens interval is the widest at the storage position, and gradually decreases as the position changes from the wide shooting position to the macro shooting position to the telephoto shooting position.
Since the focal length becomes longer as the distance between the lenses 214 and 224 becomes narrower, wide-angle shooting is possible at a wide shooting position, and enlarged shooting is possible at a telephoto (tele) shooting position.

In other words, when the camera unit 20 is rotated toward the operation surface 1S to photograph a subject in the forward direction 1F, the zoom magnification is suitable for wide photography.
When rotated upward 1U, the zoom magnification is adjusted to be suitable for macro photography, and the lens is rotated toward the non-operation surface side so that the rearward 1
When photographing the subject B, two cam grooves 111 and 112 are formed so that the zoom magnification is suitable for telephoto photographing.

This eliminates the need for the user to perform cumbersome zoom adjustment operations. By rotating the camera unit 20 according to the purpose of photographing, the zoom magnification is automatically adjusted to be suitable for the most frequent photographing method.

<3-3 Power Supply Structure> Next, a power supply structure to the camera unit 20 will be described. FIG.
As shown in (2), a flexible board 240 is mounted inside the unit case 200. As shown in FIG. 9, the flexible substrate 240 is a substantially circular substrate, and has two patterns 251 and 252 formed in a substantially semicircular arc shape. The patterns 251 and 252 are a part of the power supply circuit of the camera unit 20, and constitute a positive electrode and a negative electrode, respectively.

The cam plate 110 has the cam groove 11
The surface on which the brushes 10 and 112 are formed
7 are provided. The brush 107 is connected to a power source in the mobile phone main body 10 via a wiring (not shown) provided in the cam plate 110 and the rotating shaft 105. This allows the camera unit 20 to receive power supply from the main body via the brush 107.

FIG. 9 shows a brush 1 on a flexible substrate.
07 is shown. The brush 107 is used for the cam plate 11
0, and the cam plate 110 is fixed to the main body 10 side. Therefore, the position of the brush 107 is considered to be fixed. Then, as the camera unit 20 rotates, the flexible board 240 also rotates integrally.

The figure shows that the camera unit 20 is on the opposite side of the operation surface,
That is, this is a case where the brush 107 is rotated to a position suitable for telephoto shooting. At this time, the brush 107 and the patterns 251 and 252 are rotated.
Is the telephoto shooting position 254D on the flexible substrate 240
Are in contact.

In this state, the camera unit 20 is rotated upward, and as shown in FIG.
9, the flexible board 240 rotates 90 degrees in the direction of arrow R from the state shown in FIG.
In the vicinity of C, the brush 107 and the patterns 251, 25
2 comes into contact.

Further, as shown in FIG. 1, when the camera unit 20 is rotated to the operation surface 1S side, the brush 107 and the pattern 25 near the wide photographing position 254B.
1,252 come into contact. As described above, power is supplied from the main body 10 to the camera unit 20 at each shooting position.

When the camera unit 20 is further rotated from the state of the wide photographing position 254B to the storage state of FIG.
The brush 107 is located near 54A, but since the patterns 251 and 252 are not formed near the storage position 254A, the power supply to the camera unit 20 is cut off.

As described above, power is supplied via the brush 107 when the camera unit 20 is turned to the wide shooting, macro shooting, or telephoto shooting positions. , No power is supplied. That is, when the camera unit 20 is not used, power is cut off, so that unnecessary power consumption can be cut.

With this configuration, forgetting to turn off the power of the camera unit 20 can be eliminated. In particular, in a device such as a mobile phone in which the validity time of a charging battery is short, the merit of preventing unnecessary power consumption is great.

FIG. 10 summarizes the relationship between the rotational position of the unit camera 20, the power-off state, and the zoom position in the configuration described above.

When the rotating position of the camera unit 20 is at the stowed position, the power of the camera unit 20 is turned off, and the power is turned on during wide-angle shooting, macro shooting, and telephoto shooting.

{4. Modification In the above-described portable embodiment, when the camera unit 20 is turned to the operation surface 1S side, wide shooting is performed. When the camera unit 20 is turned to the upper direction 1U, macro shooting is performed. This is a configuration based on the premise that if moved, the frequency of telephoto shooting is high.

Therefore, a different pattern of zoom magnification may be set for the rotational position of the camera unit 20. FIG. 11 shows a combination of the rotation position and the zoom magnification of the camera unit 20 according to the above-described embodiment as a pattern 1, and another pattern 2 as an example.

In the pattern 2, when the camera unit 20 is turned to the operation surface 1S side, the zoom magnification is suitable for wide shooting, and when the camera unit 20 is turned upward 1U, it is suitable for telephoto shooting. The zoom magnification is set so that the zoom magnification suitable for macro photography is obtained when the camera is turned to the opposite side of the operation surface. In order to make such a setting, the curved shapes of the cam grooves 111 and 112 formed in the cam plate 110 may be set to corresponding shapes. Therefore, it is possible to easily cope with various patterns by changing the curved shapes of the cam grooves 111 and 112.

FIG. 13 shows an operation example in the case of performing macro photography in pattern 2. In the macro photography in the pattern 2, the camera unit 20 is rotated to the side opposite to the operation surface. Therefore, for example, with the page of the book opened, the operation surface 1S of the mobile phone 1 is turned upward, and the monitor 11 is turned on.
The macro shooting operation can be performed naturally while looking into the camera. In addition, it is convenient when shooting business cards, postcards, and the like in a state on a desk.

Of course, the camera unit 20 is
When rotated to the S side, a macro photographing pattern can be obtained, and it goes without saying that the present invention can be applied to other patterns. These specification changes,
Since this is realized by changing the shape of the cam groove of the cam plate 110, it is possible to make differently according to the target user.

[0083]

As described above, according to the first aspect of the present invention, the photographing magnification of the subject is changed in conjunction with the rotational position of the photographing device, so that the photographing magnification suitable for the rotational position of the photographing device is obtained. By setting, the troublesome zoom adjustment operation is reduced.

According to the second aspect of the present invention, the photographing magnification is changed by changing the distance between the two groups of lenses in conjunction with the rotational position of the photographing device, so that a general zoom mechanism is used. Meanwhile, it realizes the zoom interlocking function.

According to the third aspect of the present invention, the projection of the lens frame is engaged with the cam groove formed in the fixed plate, whereby the lens frame is regulated while being restricted to the shape of the cam groove. Since the lens is turned and the lens interval is changed, the turning position and the zoom mechanism can be linked without using a position sensor or an angle sensor.

According to the fourth aspect of the present invention, since the power is supplied from the main body to the photographing device by using the brush electrode, the number of wirings at the rotation fulcrum can be reduced.

According to the fifth aspect of the present invention, the main body of the electronic device is constituted by a mobile phone, so that the convenience of the camera-equipped mobile phone can be further improved.

According to the sixth aspect of the present invention, when the camera is turned to the operation surface side of the mobile phone, the zoom magnification is adjusted to be suitable for wide-angle shooting. Only with this, an appropriate zoom magnification is set, and a cumbersome zoom adjustment operation becomes unnecessary.
