[0023]

[Table 1]

EXP is 8-bit data detected from the bar code data of the film cartridge 51 shown in FIG. 3 and means the number of images that can be shot (BCD).
BCD is an abbreviation of Binary Coded Decimal, which is represented in hexadecimal notation so that a decimal number is easy to see. Originally, "12" in decimal is "0CH" in hexadecimal, but BCD
The hexadecimal number in the notation is “12H”. The reason for the BCD notation is that by displaying the data as it is, it is easy for humans to understand.

ISO is data similar to the above EXP, and means film sensitivity. FCO is 8-bit data and means the number of film frames (BCD) taken.

The CNDT is 3-bit data and is film state information indicating the state of the film. DISK is 2
Bit data, which is disk position information indicating the initial position of the data disk 53 of the film cartridge 51 shown in FIG.

The following various flags are defined and provided as follows. That is, the back cover information flag is a flag that is stored each time the back cover is opened and closed. The one-frame winding flag is a flag that is set to "1" only during one-frame winding. It becomes '0' upon completion of winding. The one-frame rewinding flag is a flag that is set to "1" during rewinding and rewinding one frame.
It becomes '0' upon completion of the rewrite operation. The exposed flag is a flag that is "0" for an unexposed film and becomes "1" once it has been exposed.

The negative / positive flag is a flag generated from barcode data as in EXP. The monochrome / color flag is a flag generated from barcode data as in EXP. The operation lock flag can be used to lock the camera operation and notify the photographer, such as when a skip has failed or when rewinding is complete.
Flag to be 1 '. The midway rewind flag is a flag that indicates whether the film has been rewound upon detection of the film end, or whether the photographer has rewound halfway through the film. Table 2 below
5 shows data composed of a plurality of records in which the number of exposures at the time of rewinding in the middle is stored as one record for each type of film.

[0029]

[Table 2]

As an example of a film to be used, FIG.
FIG. 3 shows a perspective view of a film cartridge 51. Here, FIG.
FIG. 3A is a perspective view as viewed from above, and FIG. 3B is a perspective view as viewed from below. O mark 55, D mark 56, X mark 57, and □ mark 58 formed on the upper surface of the cartridge are marks indicating "unexposed", "partially exposed", "exposed", and "developed", respectively. The black disk below the mark is attached so as to be rotatable integrally with the data disk 53 and the rotating shaft 54 shown in FIG. The mark display changes sequentially with the rotation of the data disk 53, and it is possible to determine whether the film cartridge has been exposed or has been developed.

FIG. 4 is a flowchart showing a main routine of a camera sequence as a control program executed by the CPU 28 described above. The CPU 28 as the control means 4 sequentially executes the steps of the illustrated main routine at the same time as the “power-on” of the camera.

First, initialization including initialization of RAM and ports in the CPU 28 necessary for camera operation is performed (S
1). An initial operation, that is, a "mechanical operation" is performed including mechanical initialization so that the mechanism does not perform an abnormal operation according to the state of the camera (S2). The details of the "mechanical operation" routine will be described with reference to FIG.

ON / OFF of power SW (PWR SW27)
An OFF state change is detected (S3). If there is no change, the process branches to step S6. On the other hand, from ON to OF
If there is a change to F, the process branches to step S5. If there is a change from OFF to ON, the process proceeds to the next step S4, where the lens frame unit (not shown) is moved to the LDMOT3.
By driving the lens 9, the lens is prepared from the collapsed state to a state where photographing is possible (S 4).

In step S5, the lens frame unit (not shown) is changed from the photographable state to the collapsed state, contrary to step S4 (S5). In step S6, the opening / closing of the back cover operated when the film cartridge 51 is taken in or out is detected by the ON / OFF state change of the BK SW 13 (S6). Here, BK SW13 is changed from ON to OFF
Since the change to indicates that the back cover has been changed from open to closed, the process proceeds to the next step S7. On the other hand, a change from OFF to ON indicates that the back cover has changed from closed to open.
The process branches to step S9, and when there is no change, the process branches to step S11.

In step S7, since the film cartridge 51 is loaded, an "idle feed" operation for setting the first frame of the film is performed (S7). The details of the sequence of the "idle feed" routine will be described with reference to FIG.

In step S8, the "closed" state of the back cover is changed to E
It is stored in the EPROM 47 (S8), and the process proceeds to step S11. In step S9, the “open” state of the back cover is changed to EEPRO.
It is stored in M47 (S9). The setting is made so that the shutter is not accidentally released when the image cannot be taken correctly due to "completion of rewinding", "failure of idle feeding" or the like. Then, the operation lock of the camera is released by clearing the operation lock flag (S10).

In the following step S11, a change in the rewind button (RWM SW14), which is a button for executing "rewinding in the middle" performed when it is desired to replace the film with another film when the film has not been completely photographed, is detected (step S11). S1
1). If it is detected that the rewind button is not pressed, the flow branches to step S13. When the rewind button is pressed, rewinding is set halfway (S12). However, the actual rewinding of the film is performed in step S14 described later. The details of the "midway rewind" routine will be described with reference to FIG.

In step S13, the presence or absence of a rewind request is determined based on whether or not the rewind request flag is "1" (present) (S13). The rewind request flag is set to "1" when the rewind button (RWM SW14) is pressed in the above-described step S11, or when the film end is detected by winding up one frame of the film after shooting in step S25 described later. Is set to If the rewind request flag is '1'
If it is determined that the above condition is satisfied, the process proceeds to step S14, and "rewind" of the film is performed (S14). The processing sequence of this detailed "rewind" routine will be described with reference to FIG.

Next, in step S10, the state of the operation lock flag for locking the set camera operation is determined (S15). If the operation is locked, the flow returns to step S3 to recheck the power SW. Do. It is determined whether or not the power is off (S16). If the power is off, the process returns to step S3 to check the power SW again. On the other hand, if the power is on, the process proceeds to step S17. In the case where “operation locked” and “power off” are determined in the above steps S15 and S16, the power SW (PWR SW27) and the back cover SW (BK
SW13) and only the rewind button (RWM SW14) are accepted.

Subsequently, in step S17, the release buttons (1R SW11, 1R SW12) are turned on / off.
The state of F is determined (S17). If 1R SW11
If both the switches 2 and 12 have been pressed, the process proceeds to step S18. If not, the process returns to step S3.

In step S18, an extension amount of a lens (not shown) is obtained based on a "distance measurement" operation for measuring a distance to a subject, and a shutter exposure (not shown) is obtained based on a "photometry" operation for obtaining luminance of a field. Find time (S
18). By driving the LDMOT 39, the lens is extended by the obtained extension amount to focus on the subject (S1).
9).

By driving a shutter unit (not shown),
The film is exposed for the obtained exposure time (S2
0). The lens is driven to a predetermined reset position (S2
1). Next, it is determined whether or not the idle feeding is completed (S
22) If the idle feeding has not been completed, the film cartridge 51 is not loaded in the camera, and it is not necessary to wind up the film, so the process returns to step S3.
On the other hand, if the idle feeding has been completed, it is necessary to wind up the film by one frame, so the following steps are executed.

When the film is rewound, an exposed flag indicating that the film has been exposed at least once is set to "1" in order to indicate any of unexposed, partial exposed, and already exposed (S23).
When winding one frame of film, the magnetic recording device 48
The magnetic recording prohibition flag is set to '0' to permit magnetic recording of the photographing information by using (S24). The film is wound up by one frame by the routine "winding one frame" (S25). The detailed sequence of "winding one frame" will be described with reference to FIG.

The two consecutive flowcharts shown in FIGS. 5 and 6 show the sequence of the “mechanical operation” in step S2 in FIG. It is desirable to replace the battery while the camera is powered off when removing the battery from the camera, but the mechanical operation means that the battery separates from the battery contact in the battery compartment of the camera due to some shock during the operation of the camera, and the CPU 28 If the camera is reset or if the photographer removes the battery for some reason, the camera is returned to its initial state and the necessary operations are continued.

First, necessary data from the data stored in the EEPROM 47 is read into the CPU 28 and
Deploy on AM (S30). The back cover information in the EEPROM is determined (S31).
If 'closed', the flow branches to step S53 described later. In addition,
Normally, the back cover "closed" information is stored in this EEPROM upon completion of the idle feeding operation. Therefore, if the reset is not performed during the idle feeding operation, the back cover information in the EEPROM is "open".
Remains.

If the back cover information is "open", the current back cover SW
The state of (BKSW13) is detected (S32), and if "open", the flow branches to step S53 described later. On the other hand, "closed"
If it is, then it is determined whether or not the idle feeding is completed based on the data in the EEPROM 47 (S33), and if "idling completed", the flow branches to step S53.

On the other hand, in the case of "incomplete feeding", the EEP
The reading state of the bar code in the data in the ROM 47 is determined (S34). If "bar code reading is completed", the film is ejected from the film cartridge 51 and the initial position is not clear, so the film is once read in step S41. Rewind (S41). Subsequently, the film is fed again (S42), and step S4 is performed.
Proceed to 3.

If the result of the determination at the step S34 is "barcode reading not completed", the disk position is detected and its completion is determined based on the data in the EEPROM 47 (S35). If so, the flow branches to step S38. On the other hand, if "disc position detection is not completed", the subsequent steps S36 and S37 are executed. By driving the feeding motor 37 in the reverse direction, the data disk 53 of the film cartridge 51 is moved.
Is rotated to detect the initial position of the data disk 53 (S36). Then, the initial position information of the data disk 53 and “disk position detection completed” are
7 (S37).

In step S38, the above-mentioned step S36
If the state of the film cartridge 51 detected in step 3 is neither an unexposed film nor a partially exposed film, the process proceeds to step S73 in FIG.
(S38). That is, step S73
From the display position 5 indicating that the data disk 53 has been exposed.
7 (S73), and changes the state of "failure feeding failure" to EE.
The data is stored in the PROM 47 (S74), and the operation lock flag is set to "1" to lock the operation and the EE is set.
The program is stored in the PROM 47 (S75), and a series of processes is terminated to return.

In step S39, the feeding motor 37 is driven in the reverse direction so that the film cartridge 5
1 to rotate the data disk 53, read the barcode, and read the film information (for example, ISO sensitivity,
Negative / positive, black / white / color) are detected (S39).

The film information and “reading of barcode” are stored in the EEPROM 47 (S40). The film is fed from the film cartridge 51 by driving the feed motor 37 in the normal rotation direction (S42). The perforation of the film is detected to determine the state of idle feeding (S43). Here, it is determined that "successful empty feeding" has been performed when the first frame is set. However, if the first frame is not set even after the lapse of the predetermined time, it is determined that “unsuccessful feeding has failed”. If the empty feed is successful, step S4
Steps S48 to S47 are executed.
Execute S51.

In the step S44, "Complete empty feeding" is indicated by E
It is stored in the EPROM 47 (S44). The number of film frames is set to "1" and stored in the EEPROM 47 (S4
5, S46). Subsequently, the operation lock flag is cleared to release the operation lock, and stored in the EEPROM 47 (S
47).

In step S48, since the film has come out of the film cartridge 51, the film is rewound by driving the feed motor 37 in the reverse direction (S48), and the data disk 53 is stopped at the initial position. (S49). EEPRO changes the status of "Failed feeding failure"
It is stored in M47 (S50), and the operation lock flag is set to "1".
And store it in the EEPROM 47 (S51).

Subsequently, in step S52, the "close" information of the back cover is stored in the EEPROM 47 (S52).
Since there is a possibility that the back cover can be opened during idle feeding or rewinding, the state of the back cover is detected again (S53, S54).
The back cover information of the EEPROM 47 is "closed" and the current back cover SW
If (BL SW13) is "open", the back cover "open" information is stored in the EEPROM 47 (S55).

Although the description of the partial-exposure idle feeding is omitted here, the processing steps of the above-described steps S42 to S51 will be described later with reference to steps S94 to S1 in FIG.
It is solved by making it equal to 14. Although no description is given here of the idle feeding of the "partially exposed" film, it can be solved by making the processing of steps S42 to S51 the same as steps S94 to S114 described later.

In step S56, a judgment is made as a countermeasure when a reset is applied for some reason while the film after the photographing is being wound by one frame (S56). If the flag of one frame winding is "1", "one frame winding" is performed (S57). Details will be described with reference to FIG. If the one-frame winding is normally executed, the one-frame winding flag is set to "0" and stored in the EEPROM 47 (S58).

In step S59, a check is performed during frame rewinding as a countermeasure against reset during rewriting of magnetic recording information (not shown) (S59). If it is not during rewinding, the process branches to step S64. For rewriting, after the one-frame rewinding flag is set to "1" and stored in the EEPROM 47, the film is rewound once, and then one frame is wound while recording magnetically. Therefore, (Step S60
In steps S63 to S63, the magnetic storage inhibition flag is set to "1", and one frame is wound up twice. Thereafter, the one-frame rewinding flag is set to "0" and stored in the EEPROM 47 to complete the processing.

In step S64, a reset during rewinding or a rewind request when the end of film is detected in steps S57, S61, and S62 is determined (S64). (S6
5). It is determined whether the film is exposed (S6).
6) If the film has never been exposed, the data disc 53 is stopped at the display position 55 indicating unexposed (S67), and the process proceeds to step 71.

On the other hand, if the film has already been exposed, it is further determined whether or not the film is to be rewound halfway (S6).
8) Here again, rewind button (RWM SW14)
If no rewinding instruction is given in the step S5, and if there is a rewinding request at the film end, the data disk 53 is stopped at the display position 57 indicating that the exposure has been completed (S69). on the other hand,
If rewinding is instructed halfway, the data disk 53
Is stopped at the display position 56 indicating the partial exposure (S7).
0).

In step S71, "rewind complete" is indicated by E
The operation lock flag is set to "1" so as not to shift to the photographing operation upon completion of the rewinding, and is stored in the EEPROM 47 (S72).

The flowchart of FIG. 7 exemplifies the operation of the "idle feed" routine of the film in step S7 of FIG. First, the state information of the film is cleared and stored in the EEPROM 47 (S80).

The initial position of the data disk 53 is detected by driving the feed motor 37 in the reverse direction (S
81, S82). The presence or absence of the film cartridge 51 is determined (S83). If there is no film cartridge 51, the process ends and returns.

The exposure check (S84) and the development check (S85) of the film cartridge 51 are performed. If the film cartridge 51 has been exposed or developed, the process branches to step S112 to determine that "unsuccessful feeding has failed". Then, the data disc 53 is stopped at the initial position (S112), and the "idle feed failure" state is stored in the EEPROM 47 (S113). In order to lock the operation, the operation lock flag is set to "1" and the EEPROM 47 is set. The routine is stored (S114), the routine is terminated, and the routine returns.

In step S86, "disk position detection completed" is stored in the EEPROM 47 (S86). Then, barcode data is read from the data disk 53 (S87), and the data disk 53 is stopped at the initial position (S88). "Barcode reading completed" EEP
It is stored in the ROM 47 (S89). Step S87 above
Analyze the data read in, film information (for example,
ISO sensitivity, number of images that can be shot, negative / positive, black / white / color information) are taken out, and the validity of the data is checked (S90). If the result in step S90 is correct, the flow branches to step S94 described below. If the result is not correct, the barcode is read again (S92). Branch and perform similar processing. Then, the feeding motor 37 is driven in the reverse direction (S93), and the aforementioned step S87 is performed.
Return to and read the barcode data again.

In step S94, search data (for example, ISO data, etc.) serving as a key for performing a search is selected from the intermediate rewind data shown in the list (two-dimensional table) in Table 2.
The number of images that can be taken, negative / positive or monochrome / color information) is set (S94). One record of the intermediate rewind data is composed of the following data items. That is, date data: 4 bits × 10 digits of year, month, day, hour, minute (BCD code), ISO data: 8 bits, and number of recordable images (for example, 15, 25, 40): 4 bits
X 2 digits (BCD code) and negative / positive data: 1 bit
(0: positive, 1: negative), black and white / color: 1 bit
(0: black and white, 1: color) and the number of exposures (1-39)
:) 4 bits x 2 digits (BCD code) and a total of 66 bits
It consists of.

Subsequently, the operation of searching for halfway rewind data is as follows.
When the table of the midway rewind data is searched based on the search key set in the above step S94 (S95), as a result, data on the presence / absence of the data, the location record number, and the number of shots is returned. Therefore, the following checks are sequentially performed based on the information (S9).
6-S99) If this film is an "unexposed" film, a malfunction will occur if the same type of cartridge is loaded. If the search result becomes data "present", a warning is displayed on the LCD 29. (S98), the flow branches to step S112, and the same processing as described above is performed as "jumping failure", and this routine ends and returns. Such an abnormal process needs to be performed because, if two rewinds of the same type of cartridge are permitted in the middle, there is a risk that they cannot be distinguished from each other. On the other hand, "partial exposure"
In the case of a film, if the search result is "no data", a warning display is displayed on the LCD 27 to prevent double exposure since the number of frames to be sent out of the film is not known (S9).
8) Then, the process branches to step S112, similarly deeming that "unsuccessful feeding failure", ends the routine, and returns.

In step S100, the feeding motor 37
Is driven in the normal rotation direction (S100), and the film is fed from the film cartridge 51 (S101). continue,
It is determined whether or not the idle feeding is successful (S102). Here, a predetermined number of perforations are detected within a predetermined time, and if it is detected that the first frame has been set, it is determined that "successful feeding is successful". Judgment of unsuccessful feeding ". If the jump feed is "successful", the film frame number '1' is set to EEP.
It is stored in the ROM 47 (S103). On the other hand, if the idle feeding is "failed", the process branches to step S111 described later.

In step S104, it is checked whether or not the film has been exposed (S104). If the film is not exposed, the exposed flag is reset to "0" in step S109 and stored in the EEPROM 47 (S109). Proceed to. On the other hand, in the case of the exposed film, the magnetic recording prohibition flag is set to "1" so that the partially exposed film is not subjected to magnetic recording at the time of frame advance in order to advance the frame to the unexposed frame (S105).

In steps S106 and S107, the number of exposures is obtained based on the record number of the search result of the intermediate rewind data in step S95.
1) Perform the "one frame winding" operation for the number of times (S106, S1)
07). Set the exposed flag to '1' and set the EEPROM4
7 (S108). In step S110, the completion of the idle feeding is stored in the EEPROM 47. Then, the "idling" routine is terminated and the routine returns.

The flowchart of FIG. 8 exemplifies the “midway rewind” routine in step S12 of FIG. Set the intermediate rewind flag to “1” and set the EEPROM 47
(S120). Also, set the rewind request flag to '
The value is set to 1 'and stored in the EEPROM 47 (S121).

Search data for retrieving an empty area for halfway rewind data is set (S122), and halfway rewind data is searched (S123). It is determined whether there is data to be searched (S124), and if there is data, step S126 is performed.
If not, the oldest data record of the date data is searched for and the record number is output only if the empty area cannot be detected (S5).
125).

In step S126, step S1 is executed.
23 or the new data is stored in the data area of the record number obtained in step S125 (S12).
6), end this routine and return.

The flowchart of FIG. 9 shows the “rewind” routine in step S14 of FIG. In step S130, the feeding motor 37 is driven in the reverse direction to rewind the film (S130). Output as the film moves. A perforation signal is detected (S131).

It is determined whether there is a change in the perforation signal (S132). If there is any change in the perforated signal, the above step S1
Return to 30. On the other hand, if there is no change in the perforation signal for the predetermined time, it is determined that the film is at the end, and the state that the disk is stopped is stored in the EEPROM 47 (S13).
3).

In step S134, it is checked whether or not the film has been exposed (S134). If the film has been exposed even once, the next step S135 is performed.
Proceed to. On the other hand, if not, the data disk 53
Is stopped at the unexposed position 55 (S138).

In step S135, a rewind button (R
It is determined whether the rewind is performed during the rewinding while the WM SW 14) is pressed or the automatic rewinding due to the film end (S
135), in the case of rewinding halfway, the data disk 53 is stopped at the partial exposure position 56 (S137). On the other hand, in the case of automatic rewind, the data disk 53 is moved to the exposed position 57.
(S136). Then, the "rewind complete" state and the "operation locked" state are stored in the EEPROM 47 (S139, S140).

The flowchart of FIG. 10 exemplifies the sequence of the “winding one frame” routine in step S25 of FIG. First, the flag for raising one frame is set to "1" and stored in the EEPROM 47 (S150). Also,
The feeding motor 37 is driven in the normal rotation direction to wind up the film (S151).

In step S152, it is checked whether or not magnetic recording is prohibited (S152). If the magnetic recording prohibition flag is '0', information is recorded on the film using the magnetic recording device 48 in synchronization with the movement of the film (S
153). If “1”, the process proceeds to step S154.

In step S154, a perforation signal output with the movement of the film is detected (S154).
154). Also, it is checked whether the winding of one frame of the film is completed (S155). If the winding of one frame is completed, the brake is applied to the feeding motor 37 (S16).
2) Stop the movement of the film. The frame number counter is incremented by 1 (S163), and the EEPROM 4
7 (S164). Then, step S described later
Branch to 165. On the other hand, in step S155, if the winding of one frame is not completed even after the lapse of the predetermined time, it is determined that "film end" has occurred. And set the rewind request flag to '1'
It is stored in the PROM 47 (S157, S158).

Further, the midway rewind data is searched (S15).
9) Further, the presence or absence of data is checked (S160),
If there is no data, the process proceeds to step S165. However, if there is the corresponding data, the search data is not necessary and is cleared to 0 (S161).

In step S165, the one-frame winding flag is set to "0" and stored in the EEPROM 47 (S16).
5) End this routine and return. (First Modification) FIG. 11 is a block diagram showing a configuration of an apparatus as a first modification of the first embodiment of the present invention.

And control means 4 for outputting a control signal to the rewind means. The illustrated cartridge detection means, midway rewind instruction means, and storage means are substantially the same functional blocks as those in FIG.

The control means 4 receives information from the cartridge detecting means, the midway rewind instructing means and the storage means and outputs control signals to the idle feeding means 10, the prohibiting means 8 and the rewinding means. The idle feeding means 10 receives a control signal from the control means 4 and executes an idle feeding operation for setting the unexposed frame of the film. However, when the prohibition signal from the prohibition means 8 is received, the idle feeding operation is not performed.

As described above, according to the first embodiment, when reloading a film that has been rewound halfway, the user is automatically set to the position of the unexposed portion without any operation. Therefore, the film can be effectively used without worry of double exposure. It can also be realized with a camera without a playback head, and APS
It is possible to provide a film winding device that can use not only a special film but also a DX film or the like. For the safety of the operation of this film winding device, if an unexposed film of the same type as the rewinded film is attempted to be loaded, a warning is issued, and the film is intentionally rejected. It also has an abnormal processing function that operates.

(Second Embodiment) FIG. 13 is a block diagram showing the configuration of a hoisting device according to a second embodiment of the present invention.

The release unit 11 receives the control signal from the control unit 4 and outputs a release signal to the prohibition unit 8. The rewinding means receives the control signal from the control means 4 and rewinds the film.

Next, the operation of the film winding device implemented as described above will be described with reference to a partial flowchart. (Modification 2) First, the steps in FIG. 14 will be described. FIG.
In the description of Steps S96 to S99 in the middle, a warning is issued and no attempt is made to accept an unexposed film of the same type as the film that has been rewound halfway. If the developer requests development or loses the film, the same type of film cannot be loaded. In order to solve such a special case, a warning is given to the photographer once, and the operation of the apparatus improved so that the photographer can load a new film after knowing the warning is shown in the flowchart of FIG. An example is shown. Here, when a button that is not normally operated, for example, a rewind button is simultaneously pressed when the back cover is closed, an operation is performed such that a warning display is displayed on the LCD 29 and the idle feeding is permitted.

Note that, in the partial flowchart shown in FIG. 14, the unexposed determination step S9 in FIG.
6 corresponds to step S170 in FIG. Similarly, the step S97 for determining the presence or absence of data is performed in step S17.
1, the warning display step S98 proceeds to step S175,
The determination step S99 of the presence or absence of data is performed in step S1.
76 respectively.

Therefore, only the key points of the steps for carrying out the modification will be described below. That is, the determination of the presence or absence of unexposed (S
170), if the film is “unexposed” and it is determined that there is data in the presence / absence of data (S171), that is, the same type of data as the unexposed cartridge is used as the intermediate rewind data. If there is, step S
Only when it is detected in 172 that the rewind button (RWM SW14) is pressed, the search data is cleared to "0" (S173), and a predetermined warning is displayed on the LCD 29 (S174). No, proceed to the “film sending process” step.

(Modification 2 ') The steps in FIG. 15 will be described similarly, but before that, the necessity of this will be described. In the description of steps S96 to S99 in FIG.
If you try to load a film that has been rewound halfway and the camera does not have data on the film,
The camera warns the photographer and does not accept the film load. However, if you rewind while using another camera and the number of frames shot is memorized by humans, pay attention to the operation of the camera, advance the frame by pressing the lens cap and pressing the release button Is performed manually, double exposure can be prevented, or a photograph with a video effect that has been intentionally double-exposed can be taken.

Therefore, in order to solve the special case as described above, a warning is given to the photographer once, and the photographer is aware of the fact and can load the partially exposed film. A modified example is a partial flowchart of the process illustrated in FIG. Here, similarly to FIG. 14 described above, a button not normally used when closing the back cover, for example,
When the rewind button is pressed at the same time, the operation control is modified so as to allow "idle feed" while displaying a warning on the LCD 29.

Steps S172 to S174 in FIG. 14 positioned as processing steps after the determination in step S176 correspond to steps S184 to S186 in the flowchart in FIG. Therefore, detailed description is omitted here.

As described above, according to the second embodiment, a warning is given to the photographer once if the same type of film that was previously rewound halfway cannot be loaded for some reason on the user side. After confirming the fact, the user can load a new film and use it. When the back cover is closed and the rewind button is pressed, a warning display can be performed and an empty feed can be performed.
Also, if the user has rewinded halfway with another camera and the number of frames shot has been memorized by the user, it is necessary to manually skip the double exposure while preventing double exposure or intentionally perform special video effects. Double exposure photography is also acceptable.
