Imprint data such as ``MAS'' and ``IN AMERICA'' are stored in the magnetic storage section T of the film F by the user.
In the data cell after "ID", that is, "EA", which indicates the input recording area, "MARRY CRISMAS line break" is written.
IN AMERICA'' is converted into a magnetic input form and written by the magnetic head H when the film is fed. Furthermore, the imprint data "90, WINTER" is written in the data cell after "ID" indicating the date recording area of the magnetic storage section T of the film F, that is, "BB". 90, WINTER” will be converted into a magnetic input form and written.

Next, the operation of the camera will be explained using the flowcharts shown in FIGS. 12 and 13. "Step 201" A film cartridge C is loaded into the camera, the back cover is closed, and it is determined whether a back cover switch (not shown) is turned on. And the back cover switch is O
By determining that the answer is N, the process advances to step 202. "Step 202" The film feed motor 8 is driven via the motor driver 28, and winding (auto loading) of the film F is started. "Step 203" During film winding, film information such as film sensitivity, specified number of frames, film type, etc., written in advance in the "ID" data cell indicating the film information area of the magnetic storage section T of the film F. is read out by the magnetic head H.

The read film information is amplified and A/D converted by the head amplifier 25, and then sent to the buffer 27.
The signal is then decoded by the decoder 26 and transferred to the control circuit 19. "Step 204" The number of fed frames is counted from the output of the photo reflector 7, it is determined whether the first frame has reached a predetermined position (aperture position), and it is determined that the first frame has reached a predetermined position (aperture position). Proceed to. "Step 205" Driving of the film feeding motor 8 is prohibited and film winding is stopped. "Step 206" Here, the number selected by the message selection button 104 (message for imprinting)
or a character arbitrarily entered using the button 109 in the arbitrary input operation button panel 53. Furthermore, arbitrarily input character data is temporarily stored in the EEPROM 29. "Step 207" Here, the date data selection mode is
After the code is set, input an arbitrary data format (such as "1990, Oct, 15") set by the number of times the "Year", "Month", and "Day" buttons of the correction button 101 are pressed. and temporarily stores it in the EEPROM 29. Note that details will be described later. "Step 208" The input data for imprinting is displayed on the LCD display 52 as shown in FIG. "Step 209" Determine whether switch SW1 is ON or not, and by determining that it is ON, step 21
Go to 0. “Step 210” Photometry sensor 4 and distance measurement sensor 6
a to obtain photometry and distance measurement (subject distance) information. "Step 211" The data arbitrarily input by the user (this is read from the EEPROM 29) and the imprint message (which corresponds to the number selected by the message selection button 104) This is read from a table stored in RAM 22 in advance)
, the subject distance obtained by the above-mentioned distance measurement operation, and the data
Converts data for imprinting such as data to a specified signal,
Transfer to encoder 23.

The encoder 23 encodes the transferred signal, and the next stage buffer 24 stores the encoded signal. "Step 212" It is determined whether or not the switch SW2 is turned on, and when it is determined that the switch SW2 is turned on, the process proceeds to step 213. "Step 213" Here, a known exposure operation is performed.

That is, the control circuit 19 inputs the lens position signal from the lens encoder 2b via the lens actuator 2a, and moves the photographing lens 1 to the position corresponding to the subject distance data obtained in step 209. When this occurs, a stop command is issued to the lens actuator 2a, and the driving of the photographing lens 1, that is, the focusing operation is stopped. At the same time, the shutter 3 is opened and closed for a period determined by the output of the photometric sensor 4 in step 210. "Step 214" The film feed motor 8 is driven via the motor driver 28 to start winding up the photographic frame (one frame winding). ``Step 215'' During film rewinding, various data accumulated in the buffer 24 via the head amplifier 25 are written into the magnetic storage section T of the film F by driving the magnetic head H.

At this time, as is clear from what has already been stated, the date data is the ID (=BBB) indicating the date recording area.

” is written to the data cell. Also, “HAPPY
User input data such as ``NEW YEAR'' and ``IN AMERICA'' are stored in the data cell ``ID=EA'' indicating the user input recording area, as described above.
PY NEW YEAR Line break IN AMERICA
The information is written by the magnetic head H in this manner. "Step 216" It is determined from the output of the photo reflector 7 whether or not the winding of the photographic frame has been completed, and the process proceeds to step 217 when it is determined that the winding of the photographic frame has been completed. "Step 217" Here, it is determined whether there are any unexposed frames on the film F (whether there are any remaining frames) based on the specified number of frames read out in step 203, and if there is, it is prepared for the next shooting. Therefore, the process advances to step 206 in FIG. Also,
If it is determined that there are no frames remaining on film F, proceed to step 2.
Proceed to 18. "Step 218" Drive the film feed motor 8 in the opposite direction to the above-mentioned direction via the motor driver 28 until no continuous output is inputted from the photoreflector 7.
That is, the film F continues to be rewound until the leading edge of the film passes the position of the photoreflector 7. As a result, film rewinding is completed in which only the leading edge of the film has come out of the film cartridge C.

With the above steps, the series of operations is completed.

Although not explained above, the pad 11 is controlled by the pad advance/retreat control mechanism 12 only while the film F is moving.
The magnetic head H is pressed against the magnetic head H to ensure reliable reading and writing of magnetic information.

Next, the detailed operation of step 207 shown in FIG. 12 will be explained using FIG. 14. "Step 301" It is determined whether the user input button 103 and the date mode selection button 102 have been pressed at the same time. If they have been pressed, the process advances to step 302. If it is not pressed, this routine is returned. "Step 302" It is determined how many times the "year" button of the correction button 101 has been pressed and "ENTER" has been pressed. If the result is "twice", the process advances to step 303, and "
4 times", the process advances to step 304. "Step 303" Here, assuming that the display of the last two digits of the Western calendar is selected, for example, "90" is input from the clock circuit 20. "Step 304" Here, assuming that all digits of the Western calendar have been selected, for example, "1990" is displayed in the clock circuit 20.
Enter more information. ``Step 305'' It is determined how many times the ``month'' button of the correction button 101 has been pressed and ``ENTER'' has been pressed. If the result is "twice", the process advances to step 306, and "
If it is "3 times", the process advances to step 307, and if it is "4 times", the process advances to step 308. "Step 306" Here, assuming that the numerical display of the month has been selected, for example, "10" is input from the clock circuit 20. "Step 307" Here, assuming that display of the first three letters of an alphabetic character has been selected, for example, "Oct" is input from the ROM 21. "Step 308" Here, assuming that the display based on the four seasons has been selected, for example, "SUMMER" is input from the ROM 21. "Step 309" It is determined how many times the "day" button of the correction button 101 has been pressed and "ENTER" has been pressed. In this example, it is determined whether “2 times” or “0 times” and “2 times” or “0 times” is determined.
If it is "0 times", that is, the day data is not selected as the date data for imprinting, the process advances to step 311. "Step 310" Here, assuming that numerical display of the day has been selected, for example, "31" is input from the clock circuit 20. "Step 311" Here, each input data is converted into a predetermined signal and sent to the EEPROM.
29.

Thereafter, this routine ends and the process proceeds to the main routine of step 208 in FIG.

FIGS. 15 and 16 show other embodiments of the present invention.

After pressing the user input button 103 and date mode selection button 102 at the same time to set the desired date data selection mode, press the correction button 101 as shown in FIG.

According to each of the embodiments described above, the user input button 103 and the date mode selection button 102 are simultaneously pressed to set an arbitrary date data selection mode, and the correction button 101 is pressed. By simply changing the number of times you press the year, month, and day buttons, you can change “1990” to “90” or “
Since "August" can be replaced with "Aug" or "SUMMER", the user does not have to perform troublesome external input operations each time.

[0045] Also, since each date data (year and month in the example) can be selected from a plurality of
It becomes possible to select data that more closely matches the user's preferences. Furthermore, the order of "year, month, day" may be different in different countries, and it may not be possible to tell the difference just by numerical display, but by selecting "Aug" for "August", Such inconveniences can be prevented. Furthermore, by simply adding the country-specific identification code after "month" during input, it is possible to imprint the data for "month" in the language of that country.
