Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera equipped with receiving means for receiving radio waves transmitted from the outside.

[0002]

2. Description of the Related Art When a camera capable of forming a photographed image on a recording medium such as a film and recording the photographing position information is photographed, the photographed image and the photographing position information are output in association with each other ( Can be printed). This shooting position information can facilitate the arrangement of print images and the search for digitized images. Here, the method of detecting the shooting position, that is, the position of the camera body is GPS (Global Positioning System).
em) is available.

In the position detecting method using GPS, radio waves from a plurality of GPS satellites that orbit the earth are received to measure (position) the photographing position such as latitude, longitude and altitude of the place where the camera exists. It is necessary to have a GPS receiving antenna for efficiently receiving radio waves from GPS satellites. Some cameras equipped with this GPS receiving antenna are described below.

In the camera proposed in Japanese Unexamined Patent Publication No. 8-334821, a GPS receiving antenna is arranged in a tilting portion whose angle is variable with respect to the camera body, and a posture for detecting the posture of the tilting portion. We have a sensor
The output of this attitude sensor warns when the GPS receiving antenna is not facing the sky, and the actuator drives the tilting portion so that the GPS receiving antenna faces the sky.

In the camera proposed in Japanese Patent Laid-Open No. 8-313988, a rod-shaped GPS receiving antenna can be housed in the camera body or pulled out from the camera body. When receiving radio waves, the GPS receiving antenna is pulled out and used.

Incidentally, in Japanese Patent Laid-Open No. 6-67291,
It is described that the GPS receiving antenna may be arranged inside the back cover of the camera body, above the penta prism, on the left and right of the top cover, and the like.

[0007]

However, the above-mentioned conventional camera has the following problems.

That is, in the camera disclosed in Japanese Unexamined Patent Publication No. 8-334821, since the actuator for driving the raising / lowering portion having the GPS receiving antenna is independently configured, the camera becomes large and expensive. .

Further, in the camera disclosed in Japanese Unexamined Patent Publication No. 8-313988, since the photographer has to pull out the GPS receiving antenna from the camera body, the pulling operation is troublesome and the shutter chance is missed due to this operation. It may happen. In addition, if the GPS receiving antenna is forgotten to be pulled out, it is impossible to perform positioning. On the other hand, Japanese Patent Application Laid-Open No. 6-67291 does not describe the specific arrangement of the GPS receiving antenna.

In view of the above-mentioned problems, the present invention can reliably receive the radio waves transmitted from the outside world without performing a specific operation, and can prevent the camera body from becoming large. The purpose is to provide a camera.

[0011]

According to the present invention, there is provided an optical member having a reflecting surface inclined with respect to a longitudinal direction of a photographing screen, for guiding a subject light flux from the photographing optical system to a viewfinder eyepiece optical system, and transmitting from the outside. And a receiving means for receiving the generated radio wave, and a convex portion having an inclined surface along the reflection surface of the optical member is formed on the upper surface of the camera body, wherein the receiving means is an inclination of the convex portion. It is characterized in that it is provided on the surface.

That is, by providing the receiving means on the convex portion protruding on the upper surface of the camera body, the radio wave can be received without performing a specific operation such as pulling out the antenna for receiving the radio wave as in the prior art. Making it easier.
Moreover, by providing the receiving means on the inclined surface of the convex portion, it becomes easier to receive the radio waves transmitted from directly above or diagonally above the camera body, and compared to the case where the receiving means is provided above the convex portion. The height of the camera body is suppressed.

Here, if the receiving means formed in a flat plate shape is used, the receiving means can be efficiently arranged in the space formed between the inclined surface of the convex portion and the reflecting surface of the optical member. Therefore, the size of the camera can be reduced.

On the other hand, a receiving means for receiving an electric wave transmitted from the outside and an image pickup section having a substantially rectangular image pickup screen are provided, and the direction of the maximum receiving sensitivity to the electric wave forms the outer edge of the photographing screen. You may arrange | position so that it may become a direction which is not orthogonal to any of the sides. Even if it arranges like this,
Radio waves can be easily received from directly above or diagonally above the camera body.

If at least two receiving means are provided on a pair of inclined surfaces of the convex portion facing different directions, radio waves transmitted from above the camera body at different angles can be easily received. can do.

Further, in the case where each of the plurality of operating means operated for starting the shooting preparation operation or the shooting operation uses a camera provided on the upper surface and one side surface of the camera body, The top surface or one side surface will face the sky. Therefore, by providing the receiving means on the inclined surface formed on one side surface side of the camera body of the convex portion, it is possible to direct the receiving means to the sky regardless of the shooting posture of the camera, Radio waves transmitted from the sky can be easily received. Moreover, since it is only necessary to provide the receiving means on one inclined surface of the convex portion, it is possible to prevent the camera from increasing in size and cost as compared with the case where the receiving means is provided at a plurality of places in the camera body.

Further, by making the convex portion provided with the receiving means protrude from the camera body, it is possible to improve the reception efficiency of radio waves from the outside. Here, as the convex portion, movable between the storage position and the protruding position,
If the exterior member of the illumination means that illuminates the subject with the illumination light when in the projecting position is used, the drive mechanism of the convex portion and the drive mechanism of the illumination means can be combined, so that both are configured separately. It is possible to prevent an increase in the size and cost of the camera as compared with the above.

The receiving means can be used to receive radio waves from GPS satellites.

The built-in strobe 141 is configured to move from the stored position to the projected position by using the spring force of the spring member, and is specifically described in Japanese Patent Application Laid-Open No. 5-34770.

In the structure described above, the built-in flash 14
When 1 moves to the protruding position, the GPS antennas 143 and 144 arranged in the built-in strobe 141 also move together with the built-in strobe 141. This makes it possible to improve the reception state of radio waves by the GPS antennas 143 and 144.

FIG. 1 is a cross-sectional view of the periphery of the pentaprism 124 in a direction orthogonal to the optical axis, as viewed from the rear side of the camera 101.

Here, the roof surface 1 of the pentaprism 124
As shown in FIG. 4, 24a and 124b (reflective surfaces) are inclined downward toward the camera back side while being orthogonal to each other. The flexible printed circuit board 161 is arranged along the reflecting surfaces 124a and 124b.

It is transmitted to the amplifiers 145 and 146 and the receiver 147 provided on the flexible printed circuit board 161 via 63, and the signal processing is performed as described above.

As the GPS antennas 143 and 144, for example, the micro patch strip antenna described in Japanese Patent Laid-Open No. 183327/1993 can be preferably used. This micro patch strip antenna is formed in a flat plate shape, and has the maximum receiving sensitivity in the normal direction of the plane,
This directivity is relatively dull, and is suitable for reliably receiving radio waves from GPS satellites existing in any direction in the sky.

For this, a linear dipole antenna can be preferably used. Here, it is suitable that the required length of the dipole antenna is about ¼ of the wavelength of the received radio wave, and the wavelength of the ordinary FM broadcast radio wave is about 2 to 4 m. Therefore, the total length of the dipole antenna may be several tens cm. desirable.

Since the lateral dimension of the camera 101 is smaller than this, it is difficult to dispose a dipole antenna (FM antenna 148) of several tens of cm inside the camera 101. However, in the present embodiment, the convex upper cover 103
Since the FM antenna 148 is arranged along the
The total length of the FM antenna 148 can be made longer than in the case where the antenna 148 is arranged flat in the lateral direction of the camera 101, and the deterioration of the reception sensitivity can be minimized.

The FM antenna 148 is connected to the flexible printed board 161 via the coaxial cable 164, and the output signal of the FM antenna 148 is output via the coaxial cable 164 to the flexible printed board 16.
The signal is transmitted to the amplifier 149 and the receiver 150 provided in No. 1, and the signal processing is performed as described above.

In the above configuration, the GPS antenna 1
The direction of maximum reception sensitivity at 43 is the direction indicated by arrow AR143, and the direction of maximum reception sensitivity at GPS antenna 144 is the direction indicated by arrow AR144. on the other hand,
An arrow AR151 indicates the sky direction when the camera 101 is used in the horizontal position and posture. An arrow AR152 indicates the sky direction when the camera 101 is used in a vertical position with the side on which the release button 110 is arranged facing down, and an arrow AR153 indicates that the release button 110 of the camera 101 is arranged. It is the sky direction when used in a vertical position with the side up.

The camera 101 in which the built-in strobe 141 is in the storage position is in the horizontal position, that is, the sky direction is indicated by the arrow AR15.
When shooting in the direction shown in 1, the GPS antenna 14
Since the radio wave receiving surfaces 3 and 144 face obliquely upward with respect to the arrow AR 151, the radio waves from the GPS satellites 153 to 155 in the sky reach both GPS antennas 143 and 144 favorably.

When the camera 101 in which the built-in strobe 141 is in the storage position is taken in a vertical position with the sky direction being the direction indicated by the arrow AR152, the radio wave receiving surface of the GPS antenna 143 is oblique to the arrow AR152. The radio waves from the GPS satellites 153 to 155 satisfactorily reach the GPS antenna 143 because it faces upward. further,
The camera 101 with the built-in flash 141 in the storage position,
When shooting in a vertical position with the sky direction as the direction indicated by arrow AR153, the radio wave receiving surface of the GPS antenna 144 faces obliquely upward with respect to the arrow AR153, and therefore the GPS antenna 144 receives from the GPS satellites 153 to 155. Radio waves reach well.

On the other hand, even when the built-in strobe 141 is in the projecting position, the GPS antennas 143 and 144 have the same GP as in the case where the built-in strobe 141 is in the retracted position.
Radio waves from the S satellites 153 to 155 can be received well. Here, when the built-in strobe 141 is at the projecting position, the GPS antennas 143 and 144 are set in the camera 101 more than when the built-in strobe 141 is at the stored position.
Since radio waves from the GPS satellites 153 to 155 are not blocked by the camera 101 and the hand of the photographer, the radio waves can be received well.

As in the present embodiment, the strobe cover 10
By arranging the GPS antennas 143 and 144 on the slope of No. 8, the GP can be reliably operated even when the camera 101 is photographed in either the vertical position posture or the horizontal position posture.
Radio waves from the S satellites 153 to 155 can be received.

Next, the shooting preparation operation (operation of the CPU 121) in the camera 101 will be described using the flowchart shown in FIG.

In step S1002 starting from step S1001, the camera 10 is operated by the photographer.
When the main switch 109 of No. 1 is turned on, the process proceeds to step S1003.

In step S1003, the display section 111 is caused to display information (initial screen) regarding shooting such as shooting modes. In step S1004, it is determined whether or not the photographer half-presses the release button 110, that is, whether or not the photographing preparation switch 131 (SW1) is on. Here, if SW1 is in the ON state, the process proceeds to step S1011. If SW1 is in the off state, the process returns to step S1003, the loop of steps S1003 and S1004 is circulated, and the process waits until SW1 is in the on state.

In step S1011, the state of the peripheral circuits and various switches is recognized by communicating with the peripheral circuits and various switches arranged in the camera 101.

If no camera accessory is attached to the accessory shoe 107, step S1013.
Then, by driving the strobe drive circuit 142, the built-in strobe 141 is popped up from the storage position to the protruding position. By popping up the built-in strobe 141, the GPS antennas 143 and 144 arranged in the built-in strobe 141 can easily receive the radio waves from the GPS satellites 153 to 155.

Here, the fact that the built-in strobe 141 has popped up to perform positioning may be displayed on the display portion of the camera 101. This can prevent the photographer from feeling uncomfortable even if the built-in flash 141 suddenly pops up due to a half-press operation of the release button 110 when the surroundings of the shooting are bright.

On the other hand, if it is determined in step S1012 that the camera accessory is attached to the accessory shoe 107, the process proceeds to step S1014, and the pop-up operation of the built-in flash 141 is not performed.
That is, when a camera accessory is attached to the accessory shoe 107, by prohibiting the pop-up operation of the built-in strobe 141, the built-in strobe 141 is prevented from popping up and colliding with the camera accessory.

Here, even when the built-in flash 141 does not pop up, G is provided on both sides of the flash cover 108.
Since the PS antennas 143 and 144 are arranged, it is possible to easily receive the radio waves from the GPS satellites 153 to 155 as described above.

In step S1014, the brightness of the object is measured (photometry) by driving a photometric circuit (not shown) arranged in the camera 101, and the exposure value (aperture value and shutter speed) is calculated based on the photometry result. Calculate. In step S1015, the focus adjustment state of the photographing optical system is detected, and the lens drive unit 127 is driven based on the detection result so that the focus lens is adjusted in position in the optical axis direction.

In step S1018, step S10
The position (longitude and latitude) of the camera 101 is calculated (positioning calculation) based on the signals (reception signals of GPS radio waves and FM broadcast radio waves) input in step 16 and step S1017.

In step S1019, step S10
The result of the positioning calculation performed in 18 is displayed on the display unit 111 to inform the photographer whether or not the correct positioning is performed.
In step S1020, the photographer releases the release button 11
Whether 0 is fully pressed, that is, the shooting switch 13
It is determined whether or not 2 (SW2) is on. Here, if SW2 is in the ON state, the process proceeds to the release subroutine of step S1601. If SW2 is off, the process returns to step S1013 and step S1013.
Through the loop from step S1020 to SW2
Wait until is turned on.

In this embodiment, when the release button 110 is half pressed and the camera shoe is not attached to the accessory shoe 107, the built-in strobe 141 automatically pops up. The camera 101 may be provided with an operation unit for prohibiting the built-in strobe 141 from popping up when the positioning operation by popping up the strobe 141 is unnecessary.

Next, the operation of the release subroutine will be described using the flowchart shown in FIG.

Via step S1601 to step S
In 1602, the positioning result calculated immediately before the SW2 is turned on is decided as the position information of the camera 101 at the time of photographing, and the decided positioning result is temporarily stored in the RAM in the CPU 121. In step S1603,

In step S1604, the light flux of the subject is exposed on the film 126 by running the shutter blade group in the focal plane shutter 125 based on the shutter speed calculated in step S1014 of FIG. Here, when the value of the subject brightness obtained in step S1014 is less than or equal to the predetermined value, the pop-up built-in strobe 141 or the strobe device attached to the accessory shoe 107 emits light.
