Abstract

PURPOSE:To automatically or manually set information on the number of frames for idly feeding a film loaded in the camera. CONSTITUTION:When a film is loaded into the camera, the film is identified, and either an automatically-setting mode or a manually-setting mode is selected. When the automatically-setting mode is selected, information on the number of the frames of the film stored in the camera is set to a counter and when the manually-setting mode is selected, information on the number of frames, based on a switching operation, is set on the counter. Thus, the film is idly fed to the frame position based on the information on the number of frames set on the counter. However, even after a specific information on the number of frames is automatically set in the automatically-setting mode, the information on the number of frames can be manually set.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film feed device for a camera that feeds a film to a predetermined frame position when the film is reloaded after being taken out midway without photographing the final frame.

0002

[Prior Art] Conventionally, regarding the technique of taking out a film loaded in a camera midway through the camera without using it to the final frame and using this film again, for example, US Pat.
There is one disclosed in Japanese Patent No. 4,311,377. This allows the camera to store information about the exposed frames of the film, and when the film is used again, the camera will play back this information to recognize the exposed areas and direct the unexposed areas to face the aperture. It is designed to feed film.

0003

[Problems to be Solved by the Invention] However, with such a conventional device, if the film is taken out midway through the same camera, it can be reused without double exposure, but this film cannot be used in another camera. There was a problem that once it was loaded, it could not be reused. In addition, conventional devices
The camera automatically feeds the loaded film to a predetermined frame position, but in this case, if you want to empty a frame and then feed the frame past the predetermined frame position to take a picture, you can There was a problem that it could not be sent and was not easy to use.

0004

[Means for Solving the Problems] In order to solve the above problems, the camera film feed device according to the present invention has the following features:
manual setting means for manually setting frame number information for the blank feed of the film; and selection means for selecting one of the frame number information set by the manual setting means and the frame number information stored in the camera. It is equipped with the following.

[0005]

[Operation] When film is loaded into the camera, one of the frame number information set by the manual setting means and the frame number information stored in the camera is selected, and the frame position based on the selected frame number information is Sent empty-handed. As a result, the number of pieces information can be set arbitrarily by manual setting means.
Film can be freely fed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a camera film feed device according to the present invention. In the figure, 1 is a control unit that controls the entire device, 2 is a display unit that displays various displays, and 3 is ISO information (film sensitivity information, etc.)
4 is a storage section (memory) that stores information read from the film; 5 is a feeding section that feeds the film; 6 is a signal generated as the sprocket that follows the film rotates. This is a feed amount detection section that counts the amount of film fed and detects the amount of film fed. Also, M.S.
W is the main switch that turns on the system that makes up the camera, MUS is the switch that is pressed during manual turn, RSS is the switch that selects the mode, S1 is the switch that is pressed during photometering, and S2 is the switch that is pressed when shooting. , S3 is a switch that is always on and turns off when the back cover is closed, ZUS is a switch that is operated when counting up the number of pieces, ZDS is a switch that is operated when counting down the number of pieces, and SEL is an auto-turn switch. This is a switch that changes whether or not the films that have been replaced are subject to sequential replacement.

[0007]The film empty feeding device of the present invention has the following features:
In addition to the normal 4-frame fast feed, the following two fast feed modes are provided by operating each switch. That is, there is provided an arbitrary amount skipping mode called a manual skip mode and a predetermined amount skipping mode called an autoskip mode, and it is possible to feed frames according to each of these modes. In the arbitrary amount jump feed mode, the user sets the number of frames to feed, and in the predetermined amount jump feed mode, the camera memorizes the previous predetermined number of frames and uses the stored number of frames. The frame is automatically advanced. That is, when a previously used film is reloaded and partially rewound, the film is automatically fed to a predetermined frame position. This is ISO100 and I
This is done in consideration of the actual situation of users who often use SO400 films by alternately rewinding them midway and replacing them.

[0008] For this reason, the storage unit 4 stores the history of the films used before and last time. That is, the previous memory M1 stores the value N1 of the number of frames of the film shot in the previous previous time, and the previous previous IS
The ISO information of the previous film is stored in the O memory area. Further, the previous memory M2 stores the value N2 of the number of frames of the film shot last time, and
The previous ISO memory area stores ISO information of the previous film. In addition, in the case of manual U-turn (hereinafter referred to as MU), in which the unexposed part is left and rewound, a predetermined value is stored in each memory M1 and M2, but it is not possible to rewind after shooting up to the last frame. In the case of automatic U-turn (hereinafter referred to as AU), each memory M1, M
The value of 2 is 0. In addition, when in normal mode for normal shooting, there is also a switch RSS for mode selection.
When pressed, mode selection is performed in the order of normal mode → continuous shooting mode → normal mode each time this is pressed.

Next, FIGS. 2 to 8 are flowcharts illustrating the detailed operation of the film feed device of the camera according to the present invention. Further, FIG. 9 is an explanatory diagram illustrating the display state of the display section 2. As shown in FIG. (a) of the same figure shows a state in which everything is displayed, 10 is a skip mark indicating skip mode, 11 is a continuous shooting mark indicating continuous shooting mode, and 12 is the number of frames. This is the frame number display section. Further, figures (b) to (e) of the same figure show the states when the camera is in each operation mode, and the details will be described later.

First, the flowcharts in FIGS. 2 and 3 will be explained. When the back cover of the camera is closed and the switch S3 is turned from on to off, normal blank feed processing is performed in step 200. At this time, the display on the display section 2 is still in the off state. Subsequently, in step 201, it is determined whether the switch MSW is on, and when the on state is detected and the result is "Y", the normal mode is set in step 202, and "1" is displayed on the frame number display section 12. Then, in step 203, it is determined whether the switch RSS is turned on, and if this is "N", normal processing is performed in step 204, indicating that normal photography is being performed. Also, when "Y" in step 203, that is, the switch RSS
If it is turned on, the skip mode is set, and the skip mode is set in step 205 and a skip mark is displayed on the display section 2, followed by step 206.
It is determined whether the switch RSS is off. If this is turned off, then in step 207 C=A? In other words, it is determined whether the ISO information of the currently loaded film matches the previous one, and if the result is "Y", then in step 208, C=B? judgment, i.e. IS
It is determined whether the O information matches the previous one, and if it does not match and is "N", then in step 209 M1=0? In other words, it is determined whether the film has been previously AU'd. Then, if this is not the film that was AU'd the previous time, but is therefore "N", it means that it is a film that has been rewound halfway, so in step 220 the number of frames shot in the previous and previous time "N1" is set and displayed in the frame number counter, and in step 220 221 Performs the subsequent auto-skip mode processing. In this case, the user can compare in advance the number of frames he or she expected with the result stored in the camera.

[0011] Also, when "N" is determined in step 207,
Or, if "Y" in steps 208 and 209, it means manual skip mode, and step 210
In step 210, it is determined whether the switch S1 is on, and if it is on and the result is "Y", the process proceeds to step 21.
At step 3, a subroutine for arbitrary amount blank feed processing, which will be described later, is executed and the process ends. Note that in each of the manual skip and auto skip modes described below, no photographing operation is performed even if the photographing switch S2 is pressed. Also, if "N" in step 210, step 2
At step 11, it is determined whether the switch ZUS is on, and if this on is not detected and the result is "N", it is determined at step 212 whether the switch ZDS is on. Then, when the switch ZUS or the switch ZDS is turned on in step 211 or step 212 and the result is "Y", step 21
In step 3, the arbitrary amount of blank feed processing is executed in the same manner. The reason why the switch S1 is not turned on in step 210 to immediately shift to film feeding is to prevent an inadvertent skip if the switch S1 is turned on inadvertently. Further, if the switch ZDS is not detected and becomes "N" in step 213, it is determined in step 214 whether the switch MSW is off, and if it is "N", the process returns to step 210, but if off is detected and the result is "N". If the result is "Y", the system is turned off and the display is turned off in step 215.

Next, processing in the auto-skip mode will be explained. As mentioned above, in the auto-skip mode, the number of captured frames is displayed on the frame number counter 12, but in step 221 it is determined whether the switch S1 is on, and if it is on and "Y", auto-skip starts. Therefore, the film is continuously fed to the set value, but first, in step 222, the value of the frame number counter is set to "1".
Then, in step 223, the process of feeding the film and counting up the number of frames is automatically performed to display the value of the number of frames, and then in step 224
At this point, the end of the film is determined, that is, in the case of a 36-shot film, it is determined whether the film has been fed to the 36th frame position. Then, when the value of the frame number counter becomes 36 and this value is also displayed on the frame number display section 12 and becomes "Y", step 22
At Step 5, the film feeding is stopped and the skip mark is turned off, and then at Step 226, an AU process, that is, an auto U-turn process, which will be described later, is executed, and the process ends. Also,
When the result in step 224 is "N", that is, when the fed film does not reach the end position, step 230
It is determined whether the value of the frame number counter is equal to "N1+1", that is, the number of photographed frames plus 1. In order to prevent frame duplication, the frame is fed to a frame position equal to the number of photographed frames plus 1. If this number of frames is not reached, the process returns to step 223 to execute the feeding process, etc.; however, if the above number is reached and the result is "Y", the process proceeds to step 231 to stop film feeding and turn off the skip mark. is carried out, the skip execution is memorized in step 232, and I=C, M1= in step 233.
The previous ISO information and frame number information are stored in M2, that is, the previous previous memory area. Then, the current frame number information is stored in the previous memory area by AU processing and MU processing, which will be described later, and preparation is made for the next film loading. Then, in step 234, normal processing such as photographing processing, which will be described later, is executed.

Further, if it is determined in step 221 that the switch S1 is not turned on and the result is "N", it is determined in step 240 whether the switch ZUS is on, and if this on is detected and the result is "Y", the result is determined in step 241. on the piece counter”
N1+1'' is set and displayed on the frame number display section 12. Then, in step 242, if switch ZUS is detected to be off, step 243 performs arbitrary amount jump processing, and the process proceeds to step 231 and subsequent steps. Also, in step 240, it is not possible to detect that the switch ZUS is on, and "
When the result is "N", switch Z is turned on in step 250.
Determine whether DS is on, and if it is on and "Y",
In step 251, the frame number counter is set to "N1-1" and displayed on the frame number display section 12, and then in step 252
When it is determined that switch ZDS is off, step 2
43 Execute the following processing. Also, step 250
If the on state of the switch ZDS cannot be detected and the result is "N", it is determined in step 260 that the switch RSS is on.
When this is turned on and is "Y", the number of pieces counter is returned to "1" and displayed in step 261, and
The skip mark is turned off, then the continuous shooting mark is turned on in step 262, and the switch R is turned on in step 263.
A determination is made to detect whether the SS is off. And switch RSS
When the OFF state is detected, continuous shooting mode processing, which will be described later, is executed in step 264. Also, step 260
If the on state of switch RSS cannot be detected and the result is "N", it is determined in step 270 whether the switch MSW is off, and if it is on state and "N", the process returns to step 221, but if the off state is detected If “Y”, step 2
71 to turn off the system and turn off the display.

Next, FIG. 4 is a flowchart (subroutine) illustrating the detailed operation of the above-mentioned arbitrary amount skip feeding process. First, in step 300, the switch ZUS
If it is turned on and is "Y", the number of pieces counter is counted up, but in step 301, the value of the number of pieces counter is checked to see if it is equal to "36" (in this case, 36 If this is equal to 36 and becomes "Y", it means that no further uploading is possible, and the process moves to step 303 to execute the countdown process, but when "N" Then, in step 302, a count-up operation, that is, a frame advance operation is performed, and then in step 303, it is determined whether the switch ZUS is turned off. Then, when it is detected that the switch ZUS is turned off, the switch Z
A judgment is made as to whether the DS is on, and if this on is not detected,
If it is "N", the process returns to step 300 and it is again determined whether the switch ZUS is on, but step 304
If the result is "Y", it means that the piece has moved too far, so a countdown process is performed, but first step 305 is performed.
Determine whether the value of the number of pieces counter is 1 or not,
When this value is 1 and therefore becomes “Y”, 1
Since the following settings are not possible, the process returns to step 300, but if this value is not 1 but "N", then in step 306 a countdown operation is performed, that is, the backward movement of the pieces is set, and in step 307 it is detected that the switch ZDS is off. If so, the process returns to step 300. In this way, the frame is set by manual operation at the position to be photographed, and photographing processing is performed during normal processing, which will be described later.

[0015] Also, in step 300, the switch ZUS
If ON cannot be detected and the result is "N", step 310
It is determined that the switch ZDS is on, and this is detected and the
If “Y”, the piece is to be moved backwards, so go to step 305.
If the switch ZDS is not detected to be on and the result is "N", it is determined in step 311 that the switch RSS is on, and if it is turned on and the result is "Y", the step At step 312, the skip mark is turned off, then at step 313, the frame number counter is set to "1", and at step 314, it is determined whether the switch RSS is turned off. When this is turned off, normal processing is executed in step 315 in which the frame set above, that is, the first frame, is photographed. Also, step 311
If the switch RSS is in the off state and is "N", it is determined in step 320 whether the switch S1 is on, and if this is "N", the process returns to step 300, but the switch S1 is turned on and the state is "Y". In this case, manual skip is performed, and the number of pieces set in the number of pieces counter is stored in the memory in step 321, and then in step 32
At step 2, the frame number counter is returned to "1" and this display is made on the display section 2, and at step 323, the film is fed to a position corresponding to the stored number of frames, and at the same time the number of frames is counted up. Then, in step 324, the end position is detected and judged, and when the end position is reached and the result is "Y", feeding is stopped in step 326, and then in step 327.
Performs AU processing. Also, if the terminal position is not reached and the result is "N" in step 324, the counter is set to "set + 1" in step 325.
, that is, the value of the counter is the value set in memory.
1" is added to the value. This is to prevent the piece duplication by feeding up to the value of the frame number counter plus 1. If the value of the number counter does not reach this value, it becomes "N", and in this case, the process returns to step 323 to continue feeding, but if it reaches this value and becomes "Y", the process returns from this subroutine.

Next, FIG. 5 is a flowchart illustrating normal processing. First, in step 400, it is determined whether the switch RSS is off. In addition, this switch RSS
The off judgment is made by turning off the switch R according to the flowchart shown in
Since this normal processing may be executed without detecting that the switch RSS is turned off, it is determined whether the switch RSS is turned off at the beginning of this processing. If this switch RSS is turned off and is in the "Y" state, then in step 401 it is determined whether the switch S1 is on, and when it is turned on and is in the "Y" state, in step 402 the photometry distance measurement process is performed. Then, in step 403, it is determined whether the switch S2 is on. If it is not detected in step 403 that the switch S2 is on, the process returns to step 401, and if it is detected that the switch S2 is on and the result is "Y", step 404
At step 40, switch S2 is turned on and stored.
5 Executes normal shooting processing. Also, step 4
01, when the on state of the switch S1 cannot be detected and the result is "N", the on state of the switch RSS is detected at step 410, and when it is on and the result is "Y", the state is returned to step 410.
Step 11 refers to the memory and determines whether or not the skip has been executed.
”, continuous shooting mode processing is executed in step 413. Further, when the result in step 411 is "N", it is determined in step 412 whether the switch S2 has been turned on, and if it has been performed, continuous shooting mode processing is executed in step 413, and it is determined that the process has been performed. If not, the process moves to step 205 in FIG. 2 to set the skip mode. Also, step 410
If switch RSS is not turned on in step 420, it is determined that switch MSW is turned off, and this is determined as "N".
”, the process returns to step 401, but the switch MSW
When it is detected that the system is off and the result is "Y", the system is turned off and the display is turned off in step 421.

Next, FIG. 6 is a flowchart illustrating processing in continuous shooting mode. First, in step 500, it is determined whether the switch RSS is off. In addition, this switch R
The determination of whether the switch RSS is turned off is made at the beginning of this process, since this normal processing is executed without the switch RSS being turned off in the flowchart of FIG. And this switch RSS
When the switch S1 is turned off and becomes "Y", it is determined in step 501 whether the switch S1 is on, and when it is turned on and becomes "Y", photometry and distance measurement processing is performed in step 502, and step 503 It is determined whether the switch S2 is on. If the on-state of the switch S2 is not detected in step 503, the process returns to step 501, and if the on-state is detected and the result is "Y", continuous shooting processing is executed in step 504. Also, in step 501, the switch S
If the on state of the switch RSS cannot be detected and the result is "N", the on state of the switch RSS is detected in step 510, and if the switch RSS is on and the result is "Y", the normal processing as described above is executed in step 511. Also, step 510
If switch RSS is not turned on at step 512, it is determined whether switch MSW is turned off, and this is determined as "N".
”, the process returns to step 501, but the switch MSW
When the off state is detected and the result is "Y", the system is turned off and the display is turned off in step 513.

Next, FIG. 7 is a flowchart illustrating the AU process of shooting to the end and rewinding. First, in step 600, it is determined whether the switch SEL is on,
When this is turned on and becomes "Y", M is turned on in step 601.
2=0, that is, the previous number of frames is set to 0, then the film is rewound in step 602, and the film is rewound in step 6.
At step 03, it is determined whether rewinding is complete. When rewinding is completed, the answer is "Y" and film feeding is stopped in step 604. Also, if the switch SEL is not detected to be on and is "N" in step 600, the immediately preceding MU
In order to keep the value as it is, the rewind processing from step 602 onwards is executed without setting the value in the memory M2 to 0.

Next, FIG. 8 is a flowchart illustrating the MU process of rewinding while leaving the unexposed portion. First, in step 700, the display section 2 is stored in the previous memory M2.
The value of the frame number counter displayed in is set, the film is rewound in step 701, and then it is determined in step 702 whether rewinding is complete. If the rewinding is not completed, the process returns to step 701 to perform the rewinding, but when the rewinding is completed and the answer is "Y", the film feeding is stopped at step 703.

Next, the operation of another embodiment of this film feeding device will be explained based on the flowcharts shown in FIGS. 10 to 13. First, the flowcharts in FIGS. 10 and 11 will be explained. The back cover of the camera is closed and the switch S
3 changes from on to off, normal idle feeding processing is performed in step 1200. At this time, the display on the display section 2 is still in the off state. Then step 12
At step 01, it is determined whether the switch MSW is on, and when this on is detected and the result is "Y", the normal mode is set at step 1202, and "1" is displayed on the frame number display section 12. Then, in step 1203, it is determined whether the switch RSS has been turned on for 3 seconds or more, and when this is "N",
In step 1204, continuous shooting mode processing is performed. In addition, when "Y" is determined in step 1203, that is, when the switch RSS
If RSS remains on for three seconds or more, the skip mode is set, and in step 1205 the skip mode is set and a skip mark is displayed on the display section 2, and then in step 1206 it is determined whether the switch RSS is off. If this is turned off, then in step 1208, C=B? In other words, it is determined whether the ISO information matches the previous one, and if this is a mismatch and "N", step 120 is performed.
M1=0 in 9? In other words, it is determined whether the film has been previously AU'd. If this is not the film that was AU'd the previous time, but is therefore "N", it means that it is a film that has been rewound in the middle, so in step 1220, the number of frames taken in the previous and previous shots, "N1", is set and displayed in the frame number counter.
The auto-skip mode processing from step 1221 onward in FIG. 11 is performed. In this case, the user can compare in advance the number of frames he or she expected with the result stored in the camera.

[0021] Also, in steps 1208 and 1209, "
If the result is "Y", it is the manual skip mode, and the process moves to step 1210, in which it is determined whether the switch S2 is on, and if it is turned on and the result is "Y", the counter is set to "0" in step 1213a. Thereafter, in step 1213, a subroutine for arbitrary amount blank feed processing, which will be described later, is executed and the process ends. In this case, the display changes from "1" to "0", which clearly indicates that the arbitrary amount jump feed mode has been entered. Note that in each of the manual skip and auto skip modes described below, no photographing operation is performed even if the photographing switch S2 is pressed.

Next, processing in the auto-skip mode will be explained. As mentioned above, in the auto skip mode, the number of captured frames is displayed on the frame number counter 12, but in step 1221 of FIG. To start skipping, the film is continuously fed to the set value. First, in step 1222, the value of the frame number counter is returned to "1" and this is displayed, and then in step 1.
In step 223, the film is automatically fed and the number of frames is counted up, and the value of this number of frames is displayed.In step 1224, the end is judged, that is, up to the 36th frame in the case of a film with 36 exposures. Determine whether or not it has been delivered. Then, when the value of the frame number counter becomes 36 and this value is also displayed on the frame number display section 12 and becomes "Y", the feeding of the film is stopped in step 1225, the skip mark is turned off, and the next step is continued. Then, in step 1226, AU processing, that is, auto-turn processing is executed, and the process ends. Further, when the result in step 1224 is "N", that is, when the fed film does not reach the end position, step 12
At step 30, it is determined whether the value of the frame number counter is equal to "N1+1", that is, the number of photographed frames plus 1. In order to prevent frame duplication, the frame is fed to a frame position equal to the number of photographed frames plus 1. and,
If this number of frames is not reached, the process returns to step 1223 to execute the feeding process, etc.; however, if the above number is reached and the result is "Y", the film feeding process is stopped and the skip mark is turned off in step 1231. , the skip is stored in step 1232, and I=C, M1 is stored in step 1233.
=M2, that is, the previous ISO information and frame number information are stored in the previous previous memory area. Then, AU processing, MU
The current frame number information is stored in the previous memory area during processing, and preparation is made for the next film loading. Then, in step 1234, normal processing such as photographing processing is executed.

Further, if it is determined in step 1221 that the switch S2 is not turned on and the result is "N", then in step 1240 it is determined whether the switch ZUS is on, and if this on is detected and the result is "Y", then in step 1241 on the piece counter”
N1+1" is set and displayed on the frame number display section 12. Then, if it is detected in step 1242 that the switch ZUS is off, an arbitrary amount of jump processing is performed in step 1243, and
The process moves to step 1231 and subsequent steps. In addition, in step 1240, it is not possible to detect that the switch ZUS is on, and the message "N" is displayed.
”, at step 1250 the switch ZD is turned on.
It is determined that S is on, and when it is on and "Y", the frame number counter is set to "N1-1" and displayed on the frame number display section 12 in step 1251, and then in step 1252.
When it is determined that the switch ZDS is off, step 12
43 and subsequent steps are executed. In addition, when the on state of the switch ZDS cannot be detected and is "N" in step 1250,
In step 1260, it is determined whether the switch RSS is on, and if it is on and "Y", the frame number counter is returned to "1" and displayed in step 1261, and the skip mark is turned off, and then in step 1262 Turn on the continuous shooting mark and press switch RS in step 1263.
A determination is made to detect whether S is off. Then, when it is detected that the switch RSS is off, continuous shooting mode processing is executed in step 1264. Further, if it is determined in step 1260 that the switch RSS is not turned on and the result is "N", then in step 1270 it is determined whether the switch MSW is off, and if it is in the on state and is "N", the process returns to step 1221, but if the switch MSW is turned on and the result is "N", the process returns to step 1221. If it is detected and the result is "Y", the system is turned off in step 1271 and the display is turned off.

Next, FIG. 12 is a flowchart (subroutine) illustrating the detailed operation of the above-mentioned arbitrary amount jump feed processing.
It is. First, in step 1300, switch ZU
It is determined whether S is on, and if it is on and "Y", the number of pieces counter is counted up, but in step 1301 it is determined whether the value of the number of pieces counter is equal to "36" (in this case If this is equal to 36 and becomes "Y", proceed to step 1.
At step 301a, the counter is returned to "0" and the process moves to the next step. In other words, when ZUS is turned on, the counter changes from 1 to 2...3.
A loop display of 5 → 36 → 0 → 1, etc. is performed. Then, if "N" in step 1301, step 130
A count-up operation is performed at step 2, followed by step 130.
In step 3, it is determined whether the switch ZUS is turned off. and,
If switch ZUS is detected to be off, step 130
In step 4, it is determined whether the switch ZDS is on, and if this on is not detected and the result is "N", the process returns to step 1300 and again it is determined whether the switch ZUS is on. In this case, it is first determined in step 1305 whether or not the value of the piece number counter is 0. If this value is 0 and the determination is "Y", the counter is set to "36" in step 1305a. Go back and move on to the next one. In other words, when ZDS is turned on, the counter is
A loop display of 1→0→36...2→1→0→36... is performed. Further, if the value of the frame number counter is not 1 but is therefore determined to be "N" in step 1305, a countdown operation, that is, setting of backward feeding of the pieces is performed in step 1306, and in step 1307, off of the switch ZDS is detected. and returns to step 1300.

[0025] Also, in step 1300, the switch ZUS
If ON cannot be detected and the result is "N", step 1310
It is determined that the switch ZDS is on, and this is detected and the
If “Y”, the piece is to be moved backwards, so go to step 130.
5, the process such as countdown is performed, and if the switch ZDS is not detected to be on and the result is "N", it is determined in step 1311 that the switch RSS is on, and if it is turned on and the result is "Y", In step 1312, the skip mark is turned off and the skip mode is exited. Subsequently, in step 1313, the frame number counter is set to "1", and in step 1314, it is determined whether the switch RSS is turned off. and,
When this is turned off, continuous shooting mode processing is executed in step 1315. Also, in step 1311, the switch RS
If S is off and “N”, step 1
At step 311a, it is determined whether the switch MSW is off. If the on state of the switch MSW is detected and the result is "N", it is determined in step 1320 whether the switch S2 is on, and if this is "N", the process returns to step 1300; If “Y”, step 1
At 320a, it is determined whether the counter is "0", and if it is "Y", the process returns to step 1300. In other words, when the counter is "0", there is no skipping, and when it is not "0", it is manual skipping. In step 1321, the number of pieces set in the number of pieces counter is stored in the memory, and then in step 1322, the number of pieces is The number counter is returned to "1" and this display is made on the display section 2, and the film is fed to a position corresponding to the number of frames stored in step 1323, and at the same time the number of frames is counted up. Then, in step 1324, the terminal position is detected and judged, and when the terminal position is reached and the result is "Y", feeding is stopped in step 1326, and then in step 1
327 performs AU processing. Furthermore, if the terminal position is not reached and the result is "N" in step 1324, the counter is set to "set + 1" in step 1325.
, that is, the value of the counter is the value set in memory.
1" is added to the value. This is to prevent the piece duplication by feeding up to the value of the frame number counter plus 1. If the value of the number counter does not reach this value, it becomes "N", and in this case, the process returns to step 1323 to continue feeding, but if it reaches this value and becomes "Y", the process returns from this subroutine. If the switch MSW is turned off in step 1311a and the determination is "Y", the process proceeds to step 1311b, where the system is turned off and the display is turned off.

Next, FIG. 13 is a flowchart illustrating normal processing. First, in step 400, it is determined whether the switch RSS is off. In addition, this switch RS
Since there are cases where this normal processing is executed without detecting the off state of the switch RSS in the flowchart shown in FIG. 11, etc., the off state of the switch S is determined at the beginning of this process . If this switch RSS is turned off and is in the "Y" state, then in step 1401 it is determined whether the switch S1 is on, and when it is turned on and is in the "Y" state, in step 1402 the photometry distance measurement process is performed. and in step 1403 switch S
Determine whether 2 is on. In step 1403 switch S2
If ON is not detected, the process returns to step 1401;
When ON is detected and becomes “Y”, step 1
In step 404, turning on the switch S2 is stored, and in step 1405, normal photographing processing is executed. Further, if it is not detected in step 1401 that the switch S1 is on and the result is "N", then in step 1410 it is detected that the switch RSS is on, and if it is turned on and the result is "Y", the memory is referred to in step 1411. In step 1413, it is determined whether or not the skip has been executed, and when the result is "Y" indicating that the skip has been executed, continuous shooting mode processing is executed in step 1413. Further, when "N" is determined in step 1411, it is determined in step 412 whether the switch S2 has been turned on, and if it has been performed, continuous shooting mode processing is executed in step 1413, and it is determined that it has been performed. If not, in step 1414 the RSS is set to 3.
It is determined whether or not it has been turned on for more than a second, and if this is "Y", the process moves to step 1205 in FIG. 10 to set the skip mode, and if it is "N", step 1413
Move to. Also, in step 1410, the switch RSS
If it is not detected that the switch MSW is on, it is determined in step 1420 whether the switch MSW is off, and if this is "N", the process returns to step 1401, but if it is detected that the switch MSW is off and the result is "Y", the process returns to step 1421. to turn off the system and turn off the display.

Next, FIG. 14 shows a state transition diagram summarizing the above operations. As explained above, when the film feed device according to the present invention determines that the loaded film is a film that does not meet the conditions, it immediately shifts to the manual skip mode and manually performs the desired film feed. This allows you to set the amount. In this embodiment, the skip mode is selected by reading the ISO information, but the change may be made by detecting the change between negative and reversal.

[0028]

As explained above, according to the camera film feed device according to the present invention, when film is loaded in the camera, the frame number information by the manual setting means and the frame number information stored in the camera are By selecting one of the frames, the film is skipped forward to the frame position based on the selected frame number information, so the frame number information can be set arbitrarily using the manual setting means. can be freely fed, thereby preventing double exposure, and
This has the effect of providing the user with an easy-to-use camera.
