BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera provided with a top cover on the upper surface of a camera body.

[0002]

2. Description of the Related Art Recent compact cameras have various functions such as an automatic exposure control function, a strobe function, a zoom function, and a liquid crystal display function. Along with this, on the surface of the camera body, a large number of operation buttons such as an exposure correction button, a flash forced light emission button, a date and time adjustment button, a date imprinting necessity setting button, and the like are provided.
These operation buttons are generally provided on the back side of the camera body in consideration of the operability of the photographer.

On the other hand, in order to prevent the taking lens from being scratched when carrying the camera, and to prevent dirt and dust from adhering to the taking lens, the front side of the taking lens is covered with a lens barrier when the camera is not in use. A camera that does so is known. For the same reason, it is preferable to shield the viewfinder objective window, the photometric window, the autofocus distance measuring window, and the like exposed on the front surface of the camera body when the camera is not used. Also, since many of the operation buttons exposed on the back side of the camera body are not always operated, it is preferable to shield unused operation buttons to prevent erroneous operation. .

Some cameras having a finder cover for closing the finder objective window and the like have been known so far. In the most common form, a slide type barrier is provided on the front surface of the camera body, and this barrier covers both the front surface of the taking lens and the front surface of each window such as the viewfinder objective window. This barrier is movable in the longitudinal direction of the camera body, that is, when the camera body is viewed from the front, the barrier can be moved in the left-right direction, and by sliding the barrier during shooting, the taking lens and the viewfinder objective window are in front. It is supposed to be exposed.

As described above, the one in which both the taking lens and the viewfinder objective window are opened and closed by the slide barrier provided on the front surface of the camera body has the advantages of a simple structure and a low manufacturing cost. However, there is a drawback that the camera body tends to become large because the slide barrier becomes large and a retractable space is indispensable at the front of the camera body when the slide barrier is opened.

When the front side of the viewfinder objective window is opened and closed by a dedicated viewfinder cover, the viewfinder objective window is provided above the front side of the camera body having a substantially rectangular box shape. Similarly, there is no choice but to use a structure in which the finder cover is slid in the left-right direction of the camera body. However, in such a structure, not only a retractable space is needed when the finder cover is opened, but a light metering window for subject brightness measurement, a distance measuring window for autofocus, or a strobe light emitting window is arranged in this retracted space. Can not do. In addition, it is impossible to cover the front side and the back side of the camera body integrally with a slide-movable cover that opens and closes in the lateral direction, and in order to cover the operation buttons provided on the back side of the camera body, You must provide a dedicated cover.

The present invention has been made in view of the above circumstances, and provides a camera in which the viewfinder objective window on the front side of the camera body and the operation buttons on the rear side can be integrally covered without hindering the downsizing of the camera body. The purpose is to do.

The lens barriers 40a and 40b are also closed. Therefore, when the camera is not used, the main components are shielded from the outside, so that the camera is not damaged or soiled when being carried. Further, since the click ball 36 is fitted into the click hole 35b to lock the top cover 30 at the closed position, the top cover 30 does not open accidentally when the camera is carried. Furthermore, since the cover switch 39 remains off when the top cover 30 is in the closed position, the switching transistor 53 is in the off state,
Power supply to the distance measuring circuit 54, the photometric circuit 55, the exposure control circuit 56, and the strobe circuit 57 is cut off. Therefore, the strobe circuit 57 is inoperative, and even if the release button 25 is operated, the distance measuring circuit 54 and the photometric circuit 5 are operated.
5, and the exposure control circuit 56 will not operate.

When the top cover 30 is in the closed position, the viewfinder eyepiece window 17 and the auxiliary operation window 19 are exposed on the back side of the camera body 10. As a result, the photographer operates various operation buttons provided in the auxiliary operation window 19 to open the cartridge loading chamber for film exchange, set date imprinting necessity or adjust date and time, for example. You can prepare for shooting.

When using the camera, the top cover 30 is moved to the rear side of the camera body 10 against the click stop, and the finder objective window 12, the light emitting / receiving windows 13, 14,
Metering window 15, strobe light emission window 16, viewfinder eyepiece window 1
7 and the main operation window 18 are exposed on the surface of the camera body 10, and the auxiliary operation window 19 is shielded. Then, when the top cover 30 is completely moved to the back side, the click ball 37 is fitted into the click hole 35a and the top cover 30 is click-stopped at the open position. At the same time, the cover switch 39 is turned on, and in response to this, an on signal is input from the controller 51 to the motor driver 52 and the switching transistor 53. As a result, the switching transistor 53 is turned on, power is supplied to each circuit unit, the distance measuring circuit 54, the photometric circuit 55, and the exposure control circuit 56 are in a state of waiting for a release operation, and the strobe circuit 57 supplies the main capacitor. Start charging.

When the motor driver 52 receives the ON signal from the controller 51, it drives the motor 44 to rotate the drive ring 43 clockwise in FIG. As a result, the pins 46a and 46b are engaged with the cam grooves 47a and 47, respectively.
The lens barriers 40 a and 40 b move along b and retreat to both sides of the opening 27 to open the opening 27. Then, the zoom lens barrel 29 incorporated in the opening 27 is extended to the front surface of the camera body 10.

When the photographer intends to shoot at the wide-angle end, he or she may operate the release button 25 as it is, and when he wants to change the focal length, he appropriately operates the zoom button 26.

When the photographer looks through the viewfinder eyepiece window 17 to frame the main subject at an appropriate position and presses the release button 25 halfway down, the halfway press switch 58 is turned on to activate the distance measuring circuit 54 and the photometric circuit 55. To do. Then, the distance measuring circuit 54 measures the subject distance, the photometric circuit 55 measures the subject brightness, and sends the obtained measured values to the exposure control circuit 56. Subsequently, when the photographer presses the release button 25, the full-press switch 59 is turned on and the exposure control circuit 56 operates. The exposure control circuit 56 detects the subject distance measured by the distance measuring circuit 54 and the photometric circuit 5
The shutter speed and the aperture value of the program shutter are controlled based on the subject brightness value measured in step S5. At the same time, if the subject brightness measured by the photometry circuit 55 is less than a predetermined level, the discharge tube 64 emits light at this timing when the synchro signal Sync is input to the strobe circuit 57 in synchronization with the release operation. The strobe light is emitted from the strobe light emitting window 16 toward the subject.

Since the main operation window 18 is exposed from the opening 32 on the rear side of the camera body 10, the photographer
If necessary, you can operate the auxiliary function by operating the flash's forced-flash button, exposure compensation button, self-timer button, panorama switching button, etc. On this occasion,
Since the auxiliary operation window 19 is covered by the top cover 30, various operation buttons provided in the auxiliary operation window 19 are mistakenly operated, for example, the film loading chamber is opened, or the film is wound during shooting. It is possible to prevent accidents such as returning it.

When the photographing is completed and the top cover 30 is moved to the closed position side against the click stop, the rear edge 30b of the top cover 30 and the cover switch 39 are separated from each other, and the cover switch 39 is changed from the ON state to the OFF state. Switch to. In response to this, the output signal from the controller 51 changes from the ON signal to the OFF signal. When the off signal is output from the controller 51, the zoom lens barrel 29 is first drawn into the camera body 10. At the same time, the switching transistor 53 is turned off and the distance measuring circuit 54 and the photometric circuit 5
5, the power supply to the exposure control circuit 56 and the strobe circuit 57 is cut off, and these are deactivated. Further, the motor driver 52 operates to drive the motor 44 in the reverse direction. When the motor 44 is driven in the reverse direction, the drive ring 43 rotates counterclockwise in FIG. 5, and the pins 46a and 46b move along the cam grooves 47a and 47b, respectively. As a result, the lens barriers 40a and 40b move to the front surface of the opening 27 and close the opening 27.

When the top cover 30 is completely moved to the front side, the click ball 37 is fitted in the click hole 35b and the top cover 30 is clicked and stopped at the closed position. As a result, the finder objective window 12 and the projection / reception window 1
