The holder MPU 88 displays marks 66 to 69 on the camera monitor 64 of the liquid crystal panel 54 based on the input data of the connection unit. If no mark is displayed on the liquid crystal panel 54 despite being attached to the camera body 3, this indicates a state in which a contact failure has occurred in the contact portion of the camera body 3 or the contact portion of each unit. The user can easily and reliably identify a unit having a poor contact.

The monitoring program operates according to the flowchart shown in FIG. 5 when the power of the camera 2 is turned on, during the photographing sequence, and by a periodic timer interrupt.
In this monitoring program, the body MPU 82 and the holder M
The PU 88 detects a warning state and an error state of each unit.

The body MPU 82 detects the open / closed state of the shutter device 17 by the shutter position detection circuit 80 and detects abnormal exposure with respect to the set value by the exposure monitor circuit 81, so that the warning of the shutter device 17 and the shutter drive circuit 79 and Detect error conditions.

If an operation that is basically necessary for photographing, such as film winding, is not performed, or if a signal indicating the operation is not input, it is determined that an error has occurred. An abnormal state is determined as a warning state.

If no warning or error is detected by the monitoring program, a liquid crystal panel 38 provided on the upper surface of the camera body 3 indicates that photographing preparation is completed. When the AE finder 6 is used, an operation panel 36 provided on the side of the camera body 3 is used.
The shutter speed adjustment dial 32 is operated to set the AE mode.

The framing is performed by looking into the AE finder 6, the shutter speed and the aperture value displayed inside are confirmed, and the release switch 35 is operated. When the release switch 35 is operated, the operation signal is input to the body MPU 82, and the light of the subject formed on the focus glass 26 by the light receiving element 27 of the AE finder 6 is measured. The AE finder control circuit 28 determines the shutter speed based on the set aperture value and inputs the shutter speed to the body MPU 82.

The body MPU 82 controls the shutter drive circuit 79 based on this signal, and closes the shutter blades of the shutter device 17 of the lens unit 5. Further, the body MPU 82 controls the mirror driving circuit 76 to drive the mirror mechanism 24, rotate the light shielding plate 22 and the mirror 23 to the open position, and open the opening 11 on the back side of the main body 8.

Next, the shutter blades of the shutter device 17 are opened and closed according to the aperture value set by the lens unit 5 and the shutter speed determined by the AE finder 6. The subject light transmitted through the photographing lens 16 passes through the shutter device 17, the lens board 12, the bellows 13, and the main body 8, enters the film holder 4, and exposes the photographic film 49 set on the aperture 51 of the film holder 4. I do. As soon as the shutter device 17 is closed, the mirror mechanism 24 rotates to the closed position to shield the opening 11 from light, and the shutter device 17 is opened.

In the film holder 4, the holder MPU 88
Controls the winding drive circuit 85 to drive the winding mechanism 53 to wind up the photographic film 49 by one frame and update the display of the number display 63 on the liquid crystal panel 54.

The body MPU 82 activates the monitoring program also during this photographing sequence, and confirms via the AE finder control circuit 28 whether or not the photometry on the focusing glass 26 is properly performed by the light receiving element 27. AE
The warning and error states of the finder 6 are detected.

The body MPU 82 detects the open / closed state of the shutter device 17 by the shutter position detection circuit 80 and detects abnormal exposure with respect to the set value by the exposure monitor circuit 81, so that the shutter device 17 and the shutter drive circuit 79 Detect warning and error conditions. Further, the open / close state of the mirror mechanism 24 is detected by the mirror position detection circuit 77, and the warning and error states of the mirror mechanism 24 and the mirror drive circuit 76 are detected.

The holder MPU 88 includes a winding detection circuit 86
To detect the winding of one frame after shooting, and the winding mechanism 5
3 and the warning and error states of the winding drive circuit 85 are detected.

Further, the body MPU 82 and the holder MPU
Reference numeral 88 denotes the number of operations of the shutter device 17, the mirror mechanism 24, and the winding mechanism 53, and the EEP incorporated in the lens unit 5, the camera body 3, and the film holder 4.
It is stored in the ROM 18, 78, 87.

When a warning state, for example, a warning state is detected in the shutter device 17 by the monitoring program activated when the power of the camera 2 is turned on, during a shooting sequence, or by a periodic timer interrupt, the body M
The PU 82 sets a shutter warning flag in the flag memory 90 incorporated in the holder MPU 88.

The holder MPU 88 identifies the type of the flag set in the flag memory 90 and displays a warning according to the flowchart of FIG. First, the blink counter 9
A blink count is performed at 1. Since the flag set in the flag memory 90 is a shutter warning flag,
The display of the next error unit mark is not inverted. Since the count value of the blinking counter 91 at this time is 1, the process immediately returns to the start of the blinking process.

When the blinking counter 91 again performs the blinking count, the count value becomes 2. As a result, the blinking counter 91 is reset, and the corresponding warning unit mark, the lens unit 5 of the camera monitor 64, is reset.
Is inverted. As described above, when the warning flag is set in the flag memory 90, the mark on the corresponding camera monitor 64 is inverted once during the looping of the blinking process twice, and the blinking display of the unit in the warning state is displayed. Done.

This blinking display of the warning state is continued until the warning state of the shutter device 17 is resolved and the warning flag in the flag memory 90 is reset. Also, when any one of the camera body 3, AE finder 6, and film holder 4 enters the warning state, a warning flag indicating each unit is set in the flag memory 90, and the corresponding mark blinks. Done.

According to this, the user can use the liquid crystal panel 54
By looking at the camera monitor 64, the unit in the warning state can be easily and reliably confirmed, and the warning state can be immediately resolved to prepare for the next photographing. Further, since the warning state is displayed on the liquid crystal panel 54 of the film holder 4 for displaying the number of shots, the possibility of overlooking the warning state is less than when the camera body 3 is provided.

When an error state is detected by the monitoring program, for example, an error state in the mirror mechanism 24, the body MPU 82 sets a body error flag in a flag memory 90 incorporated in the holder MPU 88.

As in the case of the warning state described above, the holder M
The PU 88 identifies the type of the flag set in the flag memory 90 and performs a warning display according to the flowchart of FIG. First, the blinking counter 91 performs a blinking count. Since the flag set in the flag memory 90 is the main body error flag, the error unit mark, that is, the mark 66 on the camera monitor 64 is highlighted next. Since the count value of the blink counter 91 at this time is 1, the process immediately returns to the start of the blink process.

When the blinking counter 91 again performs the blinking count, the count value becomes 2, and the mark 66 on the camera monitor 64 is displayed in reverse video. As described above, when the error flag is set in the flag memory 90, the mark on the camera monitor 64 is displayed in reverse every time the blinking process is looped. The cycle becomes shorter. According to this, by checking the blinking speed of the mark, it is possible to know whether the unit is in a warning state or an error state, and to perform an operation for returning from the abnormal state in accordance with the state. Thus, the camera 2 can be returned from the warning state and the error state more quickly.

The blinking display of the error state is continued until the error state of the camera body 3 is resolved and the main body error flag in the flag memory 90 is reset, similarly to the blinking display of the warning state. Also, when one of the lens unit 5, the AE finder 6, and the film holder 4 is in an error state, an error flag indicating each unit is similarly set in the flag memory 90, and the corresponding mark blinks. Done.

If no warning or error condition is detected when the power is turned on, and if a warning or error condition is detected during photographing, the holder MPU 88 switches the backlight 56 for illuminating the liquid crystal panel 54 from behind to the camera monitor 64. Flashes in sync with the mark. According to this, since the user rarely looks at the liquid crystal panel 54 during shooting, even a user who is hard to notice even if a warning or error has occurred can be reliably notified that the camera 2 is in an abnormal state. .

In the above embodiment, the mark of the camera monitor is displayed on the liquid crystal panel in advance, and the mark is displayed blinking when a warning or error condition occurs. However, the mark is displayed normally. Alternatively, the mark may be displayed only when a warning or error condition occurs. Further, the unit name may be directly displayed on the liquid crystal panel without using the mark indicating the unit.

Further, the blinking period is changed between the warning state and the error state. However, the position where the mark is displayed is changed between the warning state and the error state, and the backlight is synchronized with the flashing light emission at the time of the error. You may make it do.
Further, at the time of error, each mechanism of the camera may be locked so that photographing cannot be performed.

Although the warning and error display is performed on the liquid crystal panel of the film holder, the warning and error display may be performed on the liquid crystal panel of the camera body or in the viewfinder.

Further, although the description has been made of a single-lens reflex camera with a lens shutter as an example, the present invention can be applied to a single-lens reflex camera in which a shutter is incorporated in a camera body. In addition to the above system cameras, the present invention can be used for a compact camera or the like in which each mechanism is unitized inside.

[0060]

As described above, according to the camera of the present invention, the unit in which an error has occurred can be easily and reliably known, so that the recovery from the error can be performed appropriately and promptly. Can be.

Further, since an error is displayed on the liquid crystal panel of the film holder which displays the number of shots which are often confirmed during shooting, the error can be more reliably given to the user than when an error is displayed on the camera body. I can let you know. Further, the backlight that illuminates the liquid crystal panel from behind is also made to blink in conjunction with the blinking display of the liquid crystal panel, so that the user can be more reliably notified of the error.
