[0002]

2. Description of the Related Art Conventionally, when it is necessary to take a plurality of photographed photographs, the film is developed or simultaneously printed, and the finished negative film or photograph is confirmed to reprint the required number of sheets. Either by ordering, or by the photographer making a note of the frame number and the number of prints required for that frame in advance, when requesting simultaneous printing, indicate that and obtain multiple required photos. Was doing.

However, these conventional methods have the drawback that they are very cumbersome and time-consuming. Therefore, in order to eliminate such conventional problems, USP 254,908
Nos. US Pat. No. 255,672 and US Pat. No. 254,982, it has been proposed to provide a magnetic recording band on a roll film and record the shooting information and the number of prints of each frame when shooting.

[0004]

However, there are many unclear points in the proposed means, because the specific information input method by the camera is not specified. Therefore, as a means for recording the information on the number of prints, it is usually conceivable to provide an operation member for setting the number of prints of a photograph. However, if such means is provided, the number of operating members increases, which complicates the operation, and increases the number of parts, which leads to an increase in size of the camera and an increase in cost, which is not preferable.

An object of the present invention is to provide a camera using a film having the above-mentioned information recording unit, in order to instruct the laboratory of the number of prints by the recording unit, so that it is specially used when recording the number of prints of a photograph with the camera. It is possible to record the information on the number of prints in the information recording section on the film by using the conventional switch etc. on the camera without newly providing the operation member of, and further It is to provide a camera that can easily initialize or continue the information.

Next, the operation sequence of the print number instruction device of this embodiment will be described with reference to the flow charts shown in FIGS. First, in step S1, the operation sequence starts and the process proceeds to step S2. In step S2, each setting is initialized and the process proceeds to step S3. In step S3, the register for counting the number of printed sheets is reset. This is because the content of the number of prints stored by the number-of-prints determination unit 4 in FIG.
The information is erased and reset by the information erasing means 16. Then, the process proceeds to step S4. In step S4, it is determined whether or not the first operating means is operated, and if not, the process proceeds to step S18. In step S4, if the first operating means 1 is operated, the process proceeds to step S5. In step S5, it is determined whether or not the second operating means 2 is operated, and if not, the process proceeds to step S18. Same step S
If the second operating means 2 is operated at 5, the process proceeds to step S6.

In step S6, the fact that the mode for printing the number of photographs has been entered by simultaneously operating the first operating means 1 and the second operating means 2 will be described later in FIG. 8 (A). The display means 18 (display means 11) is made to blink as in the upper left portion, and the process proceeds to step S7. The number displayed at the lower left of the display unit 18 in FIG. 8A is the number of prints, and is set to "1" here. In step S7, it is determined whether or not the repeat button 9 has been pressed, and if it has been pressed, step S1
Go to 5. As described above, the repeat button 9 is a button for setting the number of prints of the previously instructed photograph with one touch. If the repeat button 9 is not pressed in step S7, the process proceeds to step S8.
In step S8, the operation of the first operating means is checked, and if the first operating means 1 is not pressed, the operation proceeds to step S10. In the same step S8, the first operation means 1
If is pressed, the process proceeds to step S9.

In step S9, the register for counting the number of prints in the number of prints determination means 4 is incremented (+1) and the process proceeds to step S10. In step S10, the operation of the second operating means 2 is checked, and if the second operating means 2 is not pressed, the process proceeds to step S12. If the second operation means 2 is pressed in step S10, the process proceeds to step S11. In step S11, the register for counting the number of prints in the number of prints determination means 4 is decremented (-1), and the process proceeds to step S12.

In step S12, it is determined whether or not the number of prints of the photograph has been confirmed and entered, and if it has been entered, the process proceeds to step S16. This step S1
In 2, as in steps S4 and S5 described above,
Whether or not the number of prints has been determined is determined by whether or not the first operation means 1 and the second operation means 2 have been operated again at the same time. In step S12 above,
If the number of additional copies of the photo is not confirmed, step S1
Go to 3.

In step S13, it is determined whether an exposure start signal has been input. This is to prioritize the input of the exposure start signal even if the final print number is not input. If not input here, the process returns to step S7. Then, the setting of the number of prints is accepted and this loop is repeated.
In step S13, if the exposure start signal is input, the process proceeds to step S14.

Here, step S4 and step S
Returning to step 5, when the first operation means 1 is not operated and input in step S4 or the second operation means 2 is not operated and input 2 in step S5, that is, the first operation means 1 If the print number setting mode is not set without inputting that the second operating means 2 has been operated at the same time, the process proceeds to step S18, and in step S18, shifts to the normal operation mode of the camera. This is, for example, the first operation means 1 and the second operation means.
The operation means 2 is a zoom tele-wide operation switch, and the focal length changing means 15 operates.

Then, the process proceeds to step S19, and step S
At 19, it is determined whether an exposure start signal has been input. Here, the process proceeds from step S4 or S5 directly to step S18, the exposure is performed even when the number of prints is not set and the exposure start signal is input. Therefore, if there is the exposure start signal, the process proceeds to step S14. If the exposure start signal is not input in step S19, the process returns to step S4. Then, the operating states of the first operating means 1 and the second operating means 2 are checked, and this loop is repeated.

Further, returning to step S12, if the number of prints of the photograph is confirmed and input in step S12, the process proceeds to step S16, and in step S16, as shown in FIG. The number-of-prints confirmation display is performed in the number-of-sheets mode, and the process proceeds to step S17. In step S17, the print number information is stored in the control means 10, and the process proceeds to step S18. The steps after step S18 are as described above.

Next, returning to step S14, the number-of-prints information determined by the input of the exposure start signal is stored in the control means 10 in step S14. This is similar to step S17. And step S
In step S20, the image capturing / recording unit 8 (see FIG. 2) on the film loaded in the camera is exposed and the process proceeds to step S21. In step S21, it is determined whether or not a predetermined time required for the exposure has elapsed. If the predetermined time has not elapsed, the process returns to step S20 to continue the exposure, and if the predetermined time elapses, the process proceeds to step S22. In step S22, the magnetic head 12 (see FIG. 2) is set and the process proceeds to step S23. Step S2
At 3, the film driving means 13 starts winding the film 6, and the process proceeds to step S24.

In step S24, information on the number of prints of the photograph stored in the control means 10 during the winding operation of the film 6 is recorded by the magnetic head 12 on the information recording portion 7 on the film 6 (see FIG. 2). ) And proceed to step S25. In step S25, it is determined whether the film 6 has been wound up by a predetermined amount,
If it is not wound up, the process returns to step S24,
The number of prints of the photograph is determined by the information recording section 7 on the film 6.
Continue recording to. When the film 6 is wound up by a predetermined amount in the step S25, the process proceeds to step S26. In step S26, the winding operation of the film 6 is completed, and the process proceeds to step S27. In step S27, the print number information recorded in the information recording section 7 on the film 6 in step S24 is stored in the control means 10 and the process returns to step S3.

Here, returning to step S7, in step S7, when the number of prints of the photograph is set to be the same for a plurality of frames, by pressing the repeat button 9 (see FIGS. 2 and 4), the print set last time is set. The number of sheets can be easily set without the operations in steps S8 and S10. In step S7, it is determined whether or not the button 9 is operated. If the repeat button 9 has not been operated, the process proceeds to step S8. After step S8, the process proceeds as described above. In step S7,
When the repeat button is operated to input the value, the process proceeds to step S15. In step S15, the previously set print number for setting the current print number is read from the previously stored control unit 10 and stored in the print number determination unit 4. Then, in step S16, the number of prints is displayed on the display unit 18 for confirmation as shown in FIG. 8B.
Then, the process proceeds to step S17, and the subsequent steps are as described above.
