Means 7 and a CPU (Central) that controls them and controls the entire camera.
Processing Unit 1 constitutes a main part.

FIGS. 2 and 3 are cross-sectional views of the internal configuration of the portable camera according to the embodiment as viewed from above. FIG. 2 shows a photographing mode state, and FIG. 3 shows a portable mode state.

As shown in the figure, the camera body of the portable camera according to the present embodiment has a film winding spool chamber 1.
3, a first camera main body 16 in which a strobe main condenser 12, a battery 19 and the like are provided, and a second camera main body 17 in which a photographing lens unit 10, a pressure plate 18, a loading chamber for the film cartridge 11 and the like are provided. The first camera body 16 is configured to be able to expand and contract with respect to the second camera body 17 in the film feeding direction.

The film cartridge 11 is housed in a film cartridge loading chamber formed in the second camera body 17, and after being housed, the film 15 pulled out from the film cartridge 11 is taken up by the winding up. The take-up spool 14 in the spool chamber 13 is configured to be wound up.

In the present embodiment, the chamber wall forming the take-up spool chamber 13 is formed of an elastic member or a flexible member. The first camera body 16
Is slidably provided in the film feeding direction with respect to the second camera body 17 according to a guide or the like (not shown). That is, in a photographing mode using a camera, such as photographing, the first camera body 16 is set to be in a state of being extended in the film feeding direction (see FIG. 2). In the case of the portable mode, for example, when the first camera body 16 is contracted in the opposite direction to the above, the camera body is reduced (see FIG. 3).

At the time of reduction as shown in FIG. 3, since the take-up spool chamber 13 is formed of an elastic member or a flexible member as described above, the take-up spool chamber 13 is compressed in the film feeding direction as shown in FIG. Deform to. That is, the camera body is reduced by the amount of deformation of the take-up spool chamber 13.

Further, the photographing mode detecting means 3 and the portable mode detecting means 4 are constituted by, for example, one switch, and it is determined whether the photographing mode or the portable mode based on the state of the switch (ON / OFF). In this case, a common detection unit may be used.

FIGS. 4 and 5 are flowcharts showing the main operation of the portable camera according to the first embodiment, and the operation of the camera will be described below with reference to the flowchart.

First, the CPU 1 determines whether the power switch (not shown) of the camera is ON or OFF (step S1).
1) If the switch is OFF, go to “STOP” and ON
If so, the process proceeds to step S2. When "STOP" is entered, for example, when a switch such as a power switch or a cover of a film cartridge chamber (not shown) is changed, the program is programmed to start again from the start.

The CPU 1 determines in step S2 whether the film cartridge chamber lid has changed from the open state to the closed state, and if not, F_BKCLS.
Is set to "0" (step S4). If the flag has changed, the F_BKCLS flag is set to "1" (step S3), and the process proceeds to step S5. In step S5, the CPU 1 detects whether the mode is the photographing mode or the portable mode. If the mode is the portable mode, the process proceeds to step S26 in FIG. 5, and if the mode is the photographing mode, the process proceeds to step S6.

In step S6, the shape of the camera is changed to a photographing mode shape as shown in FIG. As the transition means, for example, means for pulling the first camera body 16 by the user or moving the first camera body 16 by the power of a motor (not shown) is used, but any means may be used as long as the transition is made. .

If it is determined in step S6 that the camera is in the photographing mode shape, the process proceeds to the next step S7 without doing anything in step S6.

In step S7, the CPU 1 detects the state of the lid of the film cartridge chamber (step S7), and if "open", returns to step S1.
If "closed", the process proceeds to step S8. In step S8, the CPU 1 determines whether the set F_BCKLS flag is “0” or “1” based on the detection result in step S2. If the flag is “0”, the process proceeds to step S15 shown in FIG. If the flag is "1", the flow advances to step S9 to read the use state of the film in the film cartridge 11 (step S9). Various means have conventionally been disclosed for reading the use state of the film 15 in the film cartridge 11, and any means may be adopted.

In steps S10 and S11, the CPU 1 determines whether the film 15 in the film cartridge 11 has not been exposed, is being used, or has been exposed to all frames, based on the use state read in step S9. If the exposure is performed, auto-loading is performed to set the first frame at the shooting position (step S12). If the frame is in use, the unexposed frame is skipped to the unexposed frame to set the shooting position (step S13). If all frames have been exposed, a display indicating that exposure has been completed is set, and step S
Proceed to 14.

As the control method in step S13, various methods are disclosed, for example, in which magnetic data of photographing information recorded in each frame is read and a frame in which magnetic data cannot be detected is determined as an unexposed frame. ,
Any method may be used.

Referring to FIG. 5, in step S15, C
PU1 determines whether the rewinding is completed, that is, whether or not the film 15 is stored in the film cartridge 11, and if it is, proceeds to step S24.
If not, the process proceeds to step S16.

The CPU 1 determines whether or not a release switch (not shown) has been pressed in step S16. If the release switch has been pressed, the CPU 1 performs a shooting subroutine (step S17) and then performs a one-frame winding subroutine (step S17). Step S18). Note that, at the same time as the film is moved during the one-frame winding, magnetic data is recorded on the film at the same time as the photographing data such as the date. A number of methods have been disclosed for magnetic recording during the one-frame winding. A method may be used.

Thereafter, in step S19, the CPU 1 determines the end of the film (whether or not the shooting of the last frame is completed). If the end of the film is not reached, the process returns to step S16. A non-volatile memory such as an EEPROM is stored (Step S20), and the film is rewound in Step S21.

If it is determined in step S16 that the release switch has not been pressed, the process proceeds to step S23, and C
The PU 1 determines whether or not a rewind switch (not shown) is pressed, and if the switch is pressed (ON), stores halfway exposed in a non-volatile memory such as an EEPROM (step S20). Rewind. Next, the CPU 1 sets the display of the use state of the film according to the use state of the film (step S22).

Thereafter, the CPU 1 determines whether the mode is the portable mode or the photographing mode (step S24).
It is determined whether the film 15 is being loaded or is being wound in the film cartridge 11 (step S25). Then, this step S25
If the film is loaded, the process returns to step S16. If the film is loaded in the film cartridge 11, the process returns to step S1 shown in FIG.

If the portable mode is set in step S24, the CPU 1 determines whether the film 15 is being loaded or being wound in the film cartridge 11 (step S26).
Here, if the film 15 is in the loaded state, the flow proceeds to step S27, and the use state of the film 15 is changed to E.
Stored in a non-volatile memory such as an EPROM,
Is rewound into the film cartridge 11 (step S
28), a film use state display is set according to the use state of the film (step S29), and the process proceeds to step S30.

On the other hand, in step S26, the film 15
If it is in a state of being caught in the film cartridge 11, the process proceeds to step S30. In this step S30, the take-up spool chamber 13 is elastically deformed as shown in FIG.
(2nd camera main body 17) side, the dimension in the width direction of the entire camera main body is reduced, and the process returns to step S1 (see FIG. 4).

In step S30, the first camera body 16
May be slid by the user, for example, or may be slid using the power of a motor (not shown). In addition, if the mobile device is already in the portable mode shape, it is removed without doing anything.

A lock member may be provided so that the first camera body 16 does not slide until the film 15 is completely rewound into the film cartridge 11.

As described above, when the portable camera of the first embodiment is set to the portable mode, the film 15
Is wound back into the film cartridge 11 and the take-up spool chamber 13 is pressed and shrunk to the empty space to reduce the size of the entire camera. When the photographing mode is set, the retracted take-up spool chamber 13 is restored to an appropriate state, and the film is unloaded based on the detection results of the film use state reading means 6 and the unexposed frame detecting means 7. The present invention is characterized in that an idle frame is fed to an exposure frame so that a photograph can be taken.

As described above, it is possible to realize a camera which is easy to take a picture at the time of taking a picture, and small and has good portability when carrying.

In FIG. 8, a state indicated by a dotted line is a photographing state, a state indicated by a dotted line in FIG. 8, and a state indicated by a solid line in FIG. 10 are a portable state. In the portable state, the belt 52 is loosened because the spool 51 moves to the film cartridge loading chamber side. The pin 54 moves in the direction of the arrow in FIG.

The film cartridge 11 is housed in a film cartridge loading chamber formed in the second camera body 17. After being stored, the film 15 pulled out from the film cartridge 11 is taken up by a take-up spool 14 in the take-up spool chamber 13.

In the second embodiment, the chamber wall forming the take-up spool chamber 13 is formed of an elastic member or a flexible member. In addition, the first camera body 1
Reference numeral 6 is provided so as to be slidable in the film feeding direction with respect to the second camera body 17 according to a guide or the like (not shown).

That is, in a photographing mode using a camera, such as photographing, the first camera body 16 is set to be in a state of being extended in the film feeding direction (see FIG. 7). Thereafter, in a portable mode, such as when carrying, the film 15 wound on the take-up spool 14 is rewound into the film cartridge 11 as described later, and after the lock by the lens frame is released, the first The camera body 16 is shrunk in the opposite direction to the above to shrink the camera body (see FIG. 9).

When the camera body is reduced as shown in FIG. 9, since the take-up spool chamber 13 is formed of an elastic member or a flexible member as described above, it is compressed in the film feeding direction as shown in FIG. Deformed to be. That is, as the take-up spool chamber 13 is deformed,
This means that the entire camera body has been reduced.

In this embodiment, as described above, the photographing state detecting means 3A and the portable state detecting means 4A are each constituted by a switch which is turned on when the camera is in the photographing state and a switch which is turned on when the camera is in the portable state. However, the present invention is not limited to this. For example, the detection unit may be configured with a single switch, and it may be determined whether the camera is in the shooting state or in the portable state based on ON / OFF of the switch. That is, the photographing state detecting unit 3A and the portable state detecting unit 4A may be configured by a common detecting unit.

FIGS. 11 and 12 are flowcharts showing the main operation of the portable camera according to the second embodiment. The operation of the camera will be described below with reference to the flowchart.

First, as shown in FIG. 11, the CPU 1
It is determined whether the cover of the loading chamber of the film cartridge 11 (not shown) has changed from the closed state to the open state (step S101). If there has been a change, the rewind completion flag is cleared in step S102 and the process proceeds to step S103. . On the other hand, if there is no change, the process proceeds to step S103.

In step S103, it is determined whether the power switch of the camera is ON or OFF (step S10).
3) If the switch is OFF, go to the "STOP"mode; if it is ON, go to step S104. When the CPU 1 determines that the "STOP" mode has been set, the program is programmed to execute again from the start when a switch such as a power switch or a lid of a film cartridge chamber (not shown) changes.

In this step S104, the CPU 1 detects whether the camera is in a photographing state or a portable state. If the camera is in the portable state, the procedure returns to step S1, and if the camera is in the photographing state, the procedure proceeds to step S105.

In step S105, the state of the lid of the loading chamber for the film cartridge 11 is determined.
Returning to step S101, if it is in the closed state, step S1
Proceed to 06.

In step S106, the mirror frame is extended to the photographing position as shown in FIG. Further, when the lens frame is extended to the photographing position, the movement of the first camera body 16 is restricted, thereby preventing a transition to the portable state (reduction).

If it is determined in step S106 that the photographing state has already been reached, the CPU 1 does nothing in step S106 and proceeds to the next step S107.

In step S107, the CPU 1 detects whether or not the film cartridge 11 is loaded in the camera (step S107). If it is not loaded, the process proceeds to step S125 shown in FIG. If so, the process proceeds to step S108.

In step S108, the CPU 1 determines whether the rewind flag is set or cleared, and if it is set, the CPU 1 executes step S1 shown in FIG.
Go to 25. On the other hand, if it has been cleared, the process proceeds to step S109, where the use state of the film in the film cartridge 11 is read (step S109).

For reading the use state of the film 15 in the film cartridge 11, various technical means have been disclosed, and any means may be adopted.

Steps S110 and S111
Then, the CPU 1 determines whether the film 15 in the film cartridge 11 has not been exposed, is in use, or has been exposed to all frames based on the use state read in step S109. That is, if the exposure has not been performed in step S110, the CPU 1 performs auto-loading to set the first frame to the shooting position (step S112).

If the CPU 1 is in use at step S111, the CPU 1 performs idle feeding to the unexposed frame to set the unexposed frame at the photographing position (step S113), and proceeds to step S116.

If all frames have been exposed, the CPU
1 sets a display indicating that exposure has been completed (step S1).
14), and set a rewind flag (step S11)
5) The process proceeds to step S125 in FIG.

As the control method in step S113, various methods are disclosed, for example, in which magnetic data of photographing information recorded in each frame is read, and a frame in which magnetic data cannot be detected is determined as an unexposed frame. Any method may be used.

The CPU 1 determines in step S116 whether or not a release switch (not shown) has been pressed.
If the release is pressed, a shooting subroutine (step S117) is performed, and then a one-frame winding subroutine is performed (step S118).

Incidentally, when the film is being moved during the above-mentioned one-frame winding, photographing data such as date is magnetically recorded on the film at the same time. A number of methods have also been disclosed for the magnetic recording during the one-frame winding. Any method may be used.

Thereafter, in step S119, the CPU 1 determines the end of the film (whether or not the shooting of the last frame is completed). If the end of the film is not reached, the process returns to step S116. A non-volatile memory such as an EEPROM is stored (step S120), and the film is rewound in step S121.

If it is determined in step S116 that the release switch has not been pressed, the process proceeds to step S124, in which the CPU 1 determines whether or not a rewind switch (not shown) has been pressed. The fact that exposure has been completed halfway is stored in a nonvolatile memory such as an EEPROM (step S120), and the film is rewound in step S121.

Next, the CPU 1 sets the display of the use state of the film according to the use state of the film (step S).
122), a rewind flag indicating that the rewind is completed is set (step S123).

Referring to FIG. 12, thereafter, CPU 1 determines whether portable mode switch 8 is on or off (step S).
If it is off, it is determined whether or not the film cartridge 11 is loaded (step S12).
6). If it is determined in step S126 that the film cartridge 11 is loaded, it is determined whether the rewind flag is "1" or "0". If "1", the process returns to step S1, and if "0", the process returns to step S1. Step S11 in FIG.
Return to 6.

If the portable mode switch 8 is on in step S125, the CPU 1 determines whether the rewinding of the film 15 has been completed (step S125).
128).

If the film 15 is in the loaded state, the flow advances to step S129 to store the use state of the film in a nonvolatile memory such as an EEPROM, and rewinds the film 15 into the film cartridge 11 (step S130). ).

In the portable state, the belt 52 is loosened because the spool 51 moves to the film cartridge loading chamber side. The pin 54 moves in the direction of the arrow in FIG.

FIGS. 16 and 17 are flowcharts showing the main operation of the portable camera according to the third embodiment, and the operation of the camera will be described below with reference to the flowchart.

First, as shown in FIG. 16, the CPU 1
It is determined whether the cover of the loading chamber of the film cartridge 11 (not shown) has changed from the closed state to the open state (step S141). If there has been a change, the rewind completion flag is cleared in step S142 and the process proceeds to step S143. . On the other hand, if there is no change, the process proceeds to step S143.

In step S143, it is determined whether the power switch of the camera is ON or OFF (step S14).
3) If the switch is off, go to the "STOP"mode; if it is on, go to step S144.

When the CPU 1 determines that the "STOP" mode has been set, the program is executed again from the start when a switch such as a power switch or a lid of a film cartridge chamber (not shown) changes.

In step S144, the CPU 1 determines whether the camera has been set to the photographing mode or the portable mode by the photographing mode setting means 20 or the portable mode setting means 21 or not. Detected by the means 4A. If the portable mode is set, the process returns to step S141. If the shooting mode is set, the process proceeds to step S145.

In step S145, the state of the lid of the loading chamber for the film cartridge 11 is determined.
Returning to step S141, if it is in the closed state, step S1
Proceed to 46.

In step S146, the camera shape is changed to the shooting mode shape as shown in FIG. As this transition means, means for moving the first camera main body 16 by the power of a motor or the like (not shown) is used.

If it is determined in step S146 that the photographing mode shape has already been set, the CPU 1 proceeds to step S146.
Then, the process proceeds to the next step S147 without doing anything.

In step S147, the CPU 1 detects whether or not the film cartridge 11 is loaded in the camera.
The process proceeds to step S166 shown in FIG. On the other hand, if loaded, it is determined whether the rewind flag is "1" or "0" (step S148), and if "0", the process proceeds to step S150.
If it is "1", the flow proceeds to step S149. Then, it is determined whether or not the mode has changed from the portable mode to the shooting mode. If the mode has changed, the process proceeds to step S150. If not, the process proceeds to step S166 in FIG.

At step S150, the CPU 1 reads the use state of the film in the film cartridge 11 (step S150).

For reading the use state of the film 15 in the film cartridge 11, various technical means have been disclosed, and any means may be adopted.

Steps S151 and S152
Then, the CPU 1 determines whether the film 15 in the film cartridge 11 has not been exposed, is in use, or has been exposed to all frames, based on the use state read in step S150. That is, if the exposure has not been performed in step S151, the CPU 1 performs auto-loading to set the first frame to the shooting position (step S153).

If the frame is being used in step S152, the CPU 1 performs idle feeding to the unexposed frame to set the unexposed frame to the photographing position (step S154). The CPU 1 sets a display indicating that exposure has been completed (step S155), sets a rewind flag (step S156), and proceeds to step S156.
Proceed to 166.

Regarding the control method in step S154, for example, various technical means for reading magnetic data of photographing information recorded in each frame and judging a frame in which magnetic data cannot be detected as an unexposed frame are disclosed. And any technical means may be used.

CPU 1 determines whether or not a release switch (not shown) has been pressed in step S157.
If the release is pressed, a shooting subroutine (step S158) is performed, and then a one-frame winding subroutine is performed (step S159).

It should be noted that, while the film is being moved during the one-frame winding, the photographing data such as the date is magnetically recorded on the film at the same time. A number of technical means are also disclosed for the magnetic recording during the one-frame winding. Any technical means may be used.

Thereafter, in step S160, the CPU 1 determines the end of the film (whether or not the shooting of the last frame is completed). If the end of the film is not reached, the process returns to step S157. A non-volatile memory such as an EEPROM is stored (step S162), and the film is rewound in step S163.

If it is determined in step S157 that the release switch has not been pressed, the flow advances to step S161 to determine whether a rewind switch (not shown) has been pressed. If the switch has been pressed (ON), the process proceeds to step S161. The fact that exposure has been performed halfway is stored in a nonvolatile memory such as an EEPROM (step S162), and the film is rewound in step S163.

Next, the CPU 1 sets the display of the use state of the film according to the use state of the film (step S1).
164), a rewind flag indicating that the rewinding has been completed is set (step S165).

Referring to FIG. 17, after that, the CPU 1 judges the mode setting by the photographing mode setting means 20 and the portable mode setting means 21 (step S166). It is determined whether it is in the loaded state (step S16)
7). If it is determined in step S167 that the film cartridge 11 is loaded, it is determined whether the rewind flag is "1" or "0" (step S16).
8) If "1", return to step S141; if "0", return to step S157.

If the portable mode is set in step S166, the CPU 1 determines whether the rewinding of the film 15 has been completed (step S1).
69).

If the film 15 is in the loaded state, the flow advances to step S170 to store the use state of the film in a nonvolatile memory such as an EEPROM and rewind the film 15 into the film cartridge 11 (step S171). ). Thereafter, the CPU 1 sets the film use state display according to the use state of the film (step S172), sets the rewind completion flag to "1" (step S173), and proceeds to step S174.

On the other hand, in step S169, the film 1
If the rewind flag 5 is in the film cartridge 11, that is, if the rewind flag is "1", the process proceeds to step S174.

In step S174, as shown in FIG. 9, the lens barrel collapses, and at the same time, the regulation of the first camera body 16 is released, and the take-up spool chamber 13 is elastically deformed. As a result, the first camera body 16 slides toward the film cartridge 11 (second camera body 17), thereby reducing the overall width of the camera body in the width direction. Thereafter, the process returns to step S141.

In the step S174, the first camera body 1
The sliding motion of 6 uses the power of a motor or the like. If it is already in the portable mode shape, the process ends without doing anything.

As described above, in the portable camera of the present embodiment, when the portable mode is selected, the film 15 is rewound into the film cartridge 11, and the empty space and the take-up spool chamber 13 are pressed and contracted. Reduce the overall size.
