Is mounted on the first imaging surface A in front of the back cover 1b, and a third lens 3 'for imaging a light beam from a subject on the CCD imaging device 4 is provided in the lens hole 1c. A shutter 5 for blocking the light from the first lens 2 and transmitting the light for a predetermined time in the camera housing 1 while allowing the CCD image pickup device 4 provided integrally to face the first imaging surface; Since the cartridge storage unit 7 for storing the silver halide film 6 disposed in A is provided, the optical axis behind the first lens 2 is not obstructed by the CCD image pickup device 4, so that the silver halide photograph and Independent or simultaneous with digital photography Can be used.

In the lens hole 1c, there is provided a fourth lens 2 'for imaging a light beam from a subject together with the third lens 3' on the CCD image pickup device, and the fourth lens 2 'behind the fourth lens 2'. By exposing the three lenses 3 'and the CCD image pickup device 4, the CCD image pickup device 4 can be protected from external force.

The operation of the above configuration will now be described. First, the embodiment shown in FIGS. 1 and 2 will be described. First, a silver halide photographic film is loaded into the patrone storage section 7. When the camera is used as a camera for silver halide photography, the operation lever 4a is operated to move the CCD image pickup device 4 to a position deviated from the optical axis of the first lens 2. 2 to form an image on the first image plane. At this time, a light beam from the subject enters through the first lens 2 and is reflected by the movable mirror 10, further reflected by the half mirror 11 (or pentaprism 14, hereinafter abbreviated), and used through the finder 12. Is imaged in the eyes of others. Further, the CCD image pickup device 4 turns on the switch 15a to notify the control unit 22 that the CCD image pickup device 4 has moved to a position deviated from the optical axis of the first lens 2, so that the control unit 22 Is turned off so that the first display unit 17 and the second display unit 13 do not operate. By adjusting the distance of the first lens 2 to the subject, focus is achieved, and by pressing the shutter button 24, the movable mirror 10 rotates upward, and the shutter 5 is opened for a predetermined time in accordance with the exposure. In this state, the light beam from the subject that has entered through the first lens 2 is irradiated on the film surface via the shutter 5 to form an image, thereby exposing the film.

Next, when using as a digital camera, the CCD image pickup device 4 is moved to the position of the optical axis of the first lens 2 by operating the moving operation lever 4a, and the light beam from the subject is transmitted to the first lens 2 Then, an image is formed on the CCD image pickup device 4 arranged on the second image forming plane via the second lens 3. At this time,
The CCD image pickup device 4 turns on the switch 15b,
Since the control unit 22 notifies the control unit 22 that the D image pickup device 4 has moved to the optical axis position of the first lens 2, the control unit 22 drives the display drive unit 23 to cause the first display unit 17 and the second display unit 13 to operate.
The image from the CCD image pickup device 4 is displayed. By looking through the viewfinder 12, the image displayed on the second display unit 13 can be viewed via the half mirror 11. Further, it is also possible to directly watch the image displayed on the first display section 17 provided on the back cover 1b. Then, as in the case of taking a silver halide photograph, the distance between the first lens 2 and the subject is adjusted to focus, and the shutter button 24 is pressed, so that the CCD image sensor 4
Can be written and stored in the memory 16. In this case, the movable mirror 10 and the shutter 5 are not operated.

Next, the operation of the embodiment shown in FIG. 4 will be described. In the present embodiment, as described above, the optical axis behind the first lens 2 is not blocked by the CCD image pickup device 4, so that the silver halide photograph and the digital photograph can be used independently or simultaneously. Can be. First, a silver halide photographic film is loaded into the patrone storage section 7. By operating the operation unit 21 to switch to the silver halide photography mode, the camera can be used as a silver halide photography camera.
At this time, the control unit 22 turns off the display driving unit 23 and
The display unit 17 may not operate. The light from the subject enters through the first lens 2 and is reflected by the movable mirror 10, is further reflected by the half mirror 11, and forms an image through the finder 12 to the eyes of the user. By adjusting the distance to the subject, focus is confirmed, and by pressing the shutter button 24, the movable mirror 10 rotates upward, and the shutter 5 is opened for a predetermined time in accordance with the exposure. In this state, a light beam from the subject that has entered through the first lens 2 is irradiated on the film surface through the shutter 5 to form an image, thereby exposing the film. Are not written into the memory 16.

Next, when the digital camera is used as a digital camera, the operation unit 21 is operated to switch to the digital photograph mode.
An image from the CCD image sensor 4 is displayed on the display unit 17. By looking through the finder 12, the subject enters through the first lens 2, is reflected by the movable mirror 10, is further reflected by the half mirror 11, and forms an image through the finder 12 to the user's eyes. At the same time, the user can view the image displayed on the first display unit 17 provided on the back cover 1b. Then, as in the case of taking a silver halide photograph, the focus is confirmed by adjusting the distance of the first lens 2 to the subject, and the image from the CCD image pickup device 4 is stored in the memory 16 by pressing the shutter button 24. Can be written and saved.
In this case, the movable mirror 10 and the shutter 5 are not operated.

Next, in the case of using as both a silver halide photograph and a digital photograph, when the operation section 21 is operated to switch to the multi mode, the control section 22 drives the display driving section 23 to drive the first display section. At 17, an image from the CCD image pickup device 4 is displayed. Then, as in the case of taking a silver halide photograph, the focus is confirmed by adjusting the distance of the first lens 2 to the subject, and the image from the CCD image pickup device 4 is stored in the memory by pressing the shutter button 24. At the same time as writing and storing in the film 16, the light from the subject which has entered through the first lens 2 is irradiated on the film surface through the shutter 5 to form an image and expose the film.
