Is a rear cover switch (S) for detecting the opening and closing of the rear cover 10.
W) 54 is connected.

A drive circuit 55 for a film feed motor 56 is connected to the CPU 50, and the film feed motor 56 is controlled by the CPU 50 and driven by the motor drive circuit 55. ing. A winding end detection circuit 57 for detecting the end of winding of the film 15 is connected to the CPU 50.
Predetermined processing is performed according to the information from the detection circuit 57.

The magnetic head portion 12 is a magnetic recording device for recording various information on the magnetic track portion of the film 15, and is driven by the magnetic head driver 58 controlled by the CPU 50.

Further, a display circuit 60 for driving the external display element 5 and the in-finder display element 16 is connected to the CPU 50. The CPU 50 controls the display circuit 60 to perform a predetermined display on the display portions 6 and 17 included in the display elements 5 and 16 described above.

Next, the operation of the camera of the first embodiment will be described with reference to FIG.
This will be described with reference to the flowchart shown in FIG.

First, in step S1, the CPU 50 detects the open / closed state of the rear lid 10 by the rear lid switch 54. Here, if the rear lid 10 is closed, then in step S2, the film feeding motor 56 is driven to perform automatic loading. After that, if the autoload is successful in step S3, the process proceeds to step S4, and if the autoload is unsuccessful, the process returns to step S1. If the rear cover 10 is closed without loading the film cartridge 14 in the camera body 1 in step S3, the autoloading will not be performed correctly, and the autoloading will fail, and the process will return to step S1.

In step S4, the CPU 50 sets the parameter PCOUNT to 1. The parameter PCOUNT corresponds to the number of prints to be magnetically recorded. Thereafter, if the release switch 51 is in the on state in step S5, the process proceeds to step S6, and if it is in the off state, the process proceeds to step S15.

The CPU 50 operates a predetermined circuit to perform the exposure operation in step S6, and then in step S6.
At 7, the film feeding motor 56 is driven to start film winding. Further, in step S8, a 20 msec timer is operated. With this timer
Wait until the film feeding speed is stabilized to some extent, and then magnetic recording is performed in step S9. In this magnetic recording, using the magnetic head 12, the date information is recorded on the magnetic track portion corresponding to each frame on the film 14,
The shooting conditions, the number of prints (PCOUNT value), etc. are recorded.

Next, in step S10, the CPU 50
Detects the end of winding by the signal from the winding end detection circuit 57, and if the winding is completed, step S1
After the PCOUNT is initialized to 1 at 1, the PCOUNT display is turned off at step S12. In the sequence of steps S15 to S21 described later, the value of PCOUNT is manually input, and the value of PCOUNT is displayed on the external display element 5 and the in-finder display element 16. In this state, the value of PCOUNT is initialized in steps S11 and S12, and
Turn off the display of UNT.

Next, in step S13, the CPU
When 50 detects that the prescribed number of frames has been shot, the film is rewound in step S14, and the process returns to step S1. In step S13, if the shooting of the specified number of frames has not been completed, step S13
Return to 5. Although not described, in the camera of this embodiment, the specified number of frames to be photographed recorded on the loaded film cartridge is read during auto loading.

At step S5, if the release switch 51 is not turned on, then at step S5.
In step 15, the CPU 50 monitors the number-of-prints setting switch 3, and if it is in the on-state, it displays PCOUNT in step S16. Here, the CPU 50
Activates the external display element 5 and the finder display element 16 via the display circuit 60, and displays the number of prints in the camera external element and the finder as shown in FIG. 1, for example.

Next, the CPU 50 resets and starts the timer TM1 in step S17, and then increments the value of PCOUNT by +1 in step S18. Thereafter, the CPU 50 detects the state of the print number setting switch 3 in step S19, and if the print number setting switch 3 is further pressed, determines the count value of the timer TM1 in step S20. If the timer TM1 is less than 2 seconds, the process returns to step S19. If it is 2 seconds or more, the PCOUNT value is initialized to 1 in step S21. The PCOUNT value changes in steps S18 and S21, but in this embodiment, the PCOUNT value changes every time it changes.
It is designed to change the display. Next in step S34
When the print number setting switch 3 is turned off at step S5, the process returns to step S5.

If the print number setting switch 3 is not turned on in step S15, C
In step S22, the PU 50 monitors the print number change switch 4 (P number change SW). If the print number changing switch 4 is on, then the timer TM2 is reset and started in step S22.

Thereafter, the CPU 50 detects the state of the print number changing switch 4 in step S24,
If the print number changing switch 4 is still on, the count value of the timer TM2 is determined in step S25. If the timer TM2 is less than 1 second, the process returns to step S24, and the timer TM2
Is more than 1 second, the film is rewound by one frame in step S26.

The CPU 50 then executes the sequence of steps S27 to S32 to rewrite the magnetic data. Since the sequence of these steps S27 to S32 is the same as the sequence of the above steps S7 to S12, detailed description thereof will be omitted here. Further, in the sequence from step S27 to step S32, the data to be rewritten is only the PCOUNT value, the data such as the date information and the photographing condition is the same as the last time, or the changed PCOUNT value.
Rewrite at the same time as the value.

Thereafter, the CPU 50 causes the step S3.
3, the state of the rewind switch 13 is monitored,
If the switch 13 is on, the process proceeds to step S14, and if it is off, the process returns to step S5.

Further, the above steps S22 and S2
In step 4, even when the print number changing switch 4 is in the off state, the process proceeds to step S33.

As described above, according to the camera of the first embodiment, it is possible to specify an arbitrary number of prints before or after shooting by a simple method.

Next, a second embodiment of the present invention will be described.

The camera of the second embodiment has substantially the same structure as that of the first embodiment, except that a mode switch is provided instead of the print number changing switch 4 (see FIG. 1) in the first embodiment. It is characterized by the presence. Therefore, only the difference will be described here, and description of other similar portions will be omitted.

In the second embodiment, the mode switch (not shown) is provided at the position of the print number changing switch 4 shown in FIG. 1 as described above. By pressing the mode switch step by step, it is possible to select three modes of the normal shooting mode, the self shooting mode, and the P mode. That is, it is possible to sequentially change by pushing the mode switch.

The P mode is a mode in which the film is not wound immediately after taking a picture, the number of prints is manually input, and after the input is completed, the film is wound and magnetic recording is performed.

Here, the operation of the second embodiment will be described with reference to FIGS.
This will be described with reference to the flowchart shown in FIG.

As shown in FIG. 5, first, in step S50, the CPU 50 detects the open / closed state of the rear lid 10 with the rear lid switch 54. Here, if the rear lid 10 is closed, then in step S51, the film feeding motor 56 is driven to perform automatic loading. After that, if the autoload is successful in step S52, the process proceeds to step S53, and if the autoload is unsuccessful, the process returns to step S50. In addition, step S52
If the rear lid 10 is closed without loading the film cartridge 14 in the camera body 1 as described above, the autoloading will not be performed correctly, and the autoloading will fail and the step S50 will be performed.
Return to

Next, the CPU 50 sets the normal mode in step S53, and then detects the state of the release switch in step S54. If the release switch is on, it is determined in step S55 whether the self mode is set. Here, if it is the self mode, the exposure of step S57 is executed after the timer for 10 seconds is operated in step S56.

If the self mode is not set in step S55, the timer is not operated and step S55 is executed.
Proceed to 57 to perform exposure. Thereafter, the CPU 50 determines in step S58 whether or not it is the P mode, and if it is in the P mode, in step S59, executes the subroutine for setting the print number (P number setting) shown in FIG. Then, after this, the process proceeds to step S60 to start film winding. In step S58,
If it is not in the P mode, the process proceeds to step S60 without executing the subroutine for setting the number of prints.

Details of the print number setting subroutine in step S59 will be described below with reference to the flowchart shown in FIG.

First, the CPU 50 initializes PCOUNT to 1 in step S100. Next, in step S101, the PCOUNT display is turned on.
Next, in step S102, if the print count setting switch 3 is on, the timer TM1 is reset and started in step S103.

Next, the CPU 50 increments the value of PCOUNT by +1 in step S104. Next, in step S105, if the print number setting switch 3 continues to be in the ON state, the timer TM1 is counted in step S106. Check the value. And
If the count value of the timer TM1 is less than 2 seconds, the process returns to step S105, and if it is 2 seconds or more, the process proceeds to step S107 to initialize PCOUNT to 1. That is, in this embodiment, if the print number setting switch 3 is kept pressed for 2 seconds or more, PCOUNT can be returned to 1. Therefore, even after the number of sheets is set to an arbitrary number, it can be returned to 1.

Subsequent Steps S108 to S110
The sequence up to is almost the same as the sequence from step S105 to step S107, and if the print number setting switch 3 is further pressed for 2 seconds, P
COUNT becomes 0. That is, the number of prints can be reduced to zero.

Thereafter, the CPU 50 causes the step S111.
If the mode switch (SW) is in the ON state, the process returns to the main routine, and if it is in the OFF state, the process returns to step S102. Further, in step S102, step S105, and step S108, even when the print number setting switch 3 is in the off state, the process proceeds to step S111 to determine the state of the mode switch. That is, the user turns on the mode switch after setting the number of prints,
The camera is set to notify the end of the print count setting.

Next, returning to FIG. 5, step S60 and subsequent steps will be described. In this step S60, the CPU 50
Starts film winding. The step S
Since 60 to step S63 are the same as step S7 to step S10 (see FIG. 4) in the first embodiment, description thereof will be omitted here.

Next, the CPU 50 turns off the PCOUNT display in step S64, and if the shooting of the specified number of frames is finished in step S65, the process proceeds to step S66 to rewind the film, otherwise, step S54. Return to. Further, after the film rewinding in step S66 is completed, the process returns to step S50.

If the release switch is not turned on in step S54, the flow advances to step S67 to determine the state of the mode switch. Here, if the mode switch is in the ON state, the process proceeds to step S68, and it is determined whether or not the mode switch is in the normal mode. If it is the normal mode, the process advances to step S69 to set the photographing mode to the self mode.

If the mode switch is not in the normal mode in step S68, the process proceeds to step S70 and it is determined whether or not the mode is the self mode. If the self mode is set, the photographing mode is set to the P mode in step S71, and if the self mode is not set, the normal mode is set in step S72.

After that, the CPU 50 determines in step S73 whether or not the rewind switch (SW) is in the ON state. Here, if it is in the ON state, the process proceeds to step S66, and if it is in the OFF state, the process returns to step S54. When the mode switch is not turned on in step S67, and also after step S69 and step S71, step S7 is performed.
Then, the process proceeds to 3 to determine whether the rewind switch (SW) is in the on state.

In the second embodiment, each time the mode switch is turned on, the mode is sequentially switched to the normal mode → self mode → P mode → normal mode.
A switch for setting the P mode may be provided separately from the switch for setting the self mode so that the P mode can be set even when the self mode is selected.

As described above, according to the camera of the second embodiment, it is possible to specify an arbitrary number of prints after photographing by a simple method. Further, since the number of prints is set after shooting and the film is wound up, the complicated operation of rewinding one frame is unnecessary as compared with the camera of the first embodiment.

Next, a third embodiment of the present invention will be described.

FIG. 7 is an external perspective view of the camera of the third embodiment as seen from the back side.

The configuration of the camera of the third embodiment is almost the same as that of the cameras of the first and second embodiments, but it indicates that the rear side of the camera body 101 has two prints.
It is characterized in that it has an ED 105 and a switch 106 for printing two sheets. Hereinafter, the above first and second
Only the differences from the embodiment will be described, and description of other configurations and actions will be omitted.

On the upper surface of the camera body 101, a mode switch 102, a display section 103, and a release button 104 are arranged as shown. The mode switch 10
2 plays the same role as the mode switch in the second embodiment.

The two-sheet print LED 105 is connected to an internal circuit of the camera body (not shown), and the above-mentioned C
The light is turned on and off by the control of a circuit equivalent to the PU 50. The light is turned off when the number of prints is one, and is turned on when the number of prints is two. Further, in the present embodiment, the number of prints is set by the switch for printing two sheets 106. When the switch is pressed once, the number of prints is changed from one to two, and when the switch is pressed again, the number of prints is returned from two to one. Thus, it changes with each pressing. The switch 10 for printing two sheets
6 is provided at a position slightly recessed from the exterior surface of the camera body 101 so that it can be turned on only when intended, without normally being turned on.

Next, the operation of the camera of the third embodiment will be described with reference to FIG.
This will be described with reference to the flowchart shown in FIG. Note that, in the figure, the operation from step S500 to step S513 is almost the same as that of the above-described first embodiment, and therefore detailed description thereof is omitted here.

The control circuit (CPU 50) executes step S5.
14, the switch for printing two sheets 106 (S
W) is detected and the switch 106 is turned on, steps S515, S516, and S517.
Then, if PCOUNT = 1, set to 2 and set to 2 if 1. Then, step S518, step S519, step S
If PCOUNT = 1 at 520, the above two-sheet print LE
D105 is turned off, and if it is 2, it is turned on.

The CPU 50 then proceeds to step S52.
When the ON state of the mode switch 102 is detected in 1, the mode is changed in step S522. Further, step S
When the ON state of the rewinding switch is detected in 523, the film is rewound in step S513.

According to the camera of the third embodiment, since the two-print LED 105 is arranged on the back side of the camera, the photographer can check the image while holding the camera.

In addition, since the number of subjects in a normal snapshot is often one or two, it is possible to set and confirm the number of prints, one or two, with the camera held, as in the present embodiment. In many cases, there is no need for additional printing.

Further, the two-sheet printing switch is arranged at a slightly depressed position so that it can be turned on only when it is intended, without being normally turned on.

As described above, according to the camera of the third embodiment, an arbitrary number of prints can be designated before photographing by a simple method. Further, since the print number setting means and the print number display means are installed on the back surface of the camera, the photographer can set the print number and confirm the print number while holding the camera.

Next, a fourth embodiment of the present invention will be described.

FIG. 9 is an external perspective view of the camera of the fourth embodiment as seen from the back side.

The structure of the camera of the fourth embodiment is substantially the same as that of the camera of the third embodiment, but a 7-segment LED indicating the number of prints is provided on the rear surface of the camera body 101.
It is characterized by including a switch 107 and a print number setting switch 108. Only the differences from the third embodiment will be described below, and the description of the other configurations and operations will be omitted.

The fourth embodiment is different from the third embodiment in that the number of prints can be set from 1 to 9. In the present embodiment, the number of prints is displayed by the 7-segment LED, but an LCD or the like may be used as long as the number of prints can be displayed.

On the upper surface of the camera body 101, the mode switch 102 and the display unit 10 are provided as in the third embodiment.
A release button 104 is provided. The mode switch 102 has the same function as the mode switch in the second and third embodiments.

The 7-segment LED 107 is connected to an internal circuit of the camera body (not shown), and the above-mentioned C
The light is turned on and off by the control of a circuit equivalent to the PU 50. Then, a numerical value is displayed according to the number of prints. In addition, in this embodiment,
The number of prints is set by the switch 108 for setting the number of prints. That is, the number of prints can be set according to the number of presses. The switch 108 for setting the number of prints is provided at a position slightly recessed from the exterior surface of the camera body 101 so that it can be turned on only when intended, without normally being turned on.

Next, the operation of the camera of the fourth embodiment will be described with reference to FIG.
This will be described with reference to the flowchart shown in FIG. In the figure, the operations from step S600 to step S613 and step S619 to step S621 are the same as those in the above-mentioned third step.
Since it is almost the same as the embodiment, the detailed description is omitted here.

When the CPU 50 detects the ON operation of the print number setting switch 108 (P number setting SW) provided on the back surface of the camera body 101 in step S614, it increments the print number PCOUNT in step S615. If PCOUNT> 5 in the subsequent steps S616 and S617, the PCOUNT is set to 1.

Next, in step S618, the CPU 50 displays the set value of PCOUNT on the 7-segment LED 107. As a result, the number of prints can be freely set from 1 to 5.

As described above, according to the camera of the fourth embodiment, an arbitrary number of prints can be designated before photographing by a simple method. Further, since the print number setting means and the print number display means are installed on the back surface of the camera, the photographer can set the print number and confirm the print number while holding the camera.
