Next, an embodiment of the operation and display according to the present invention in the camera 1 including the main body 10 and the card 60 described above will be described with reference to FIGS. In the embodiment described below, a magnetic recording area corresponding to the last exposed frame (hereinafter referred to as “previous frame”) of the exposed frames of the film loaded in the main body 10 is described. The print number data to be written is input via the switch group 136 on the card 60, and the print number data recorded in the magnetic recording area corresponding to the previous frame is rewritten. FIG. 8 is a flowchart of the previous frame rewriting of the print number data, and FIG. 9 is a diagram showing a display example in the previous frame rewriting of the print number data. In addition, what is shown in these figures is one operation example in the camera 1, and is not limited to this.

At the start of the operation flow shown in this flowchart, the camera 1 is in a photographable state. In this state, the photographer can set the photographing conditions by operating the switch group 136 of the card 60. This photographable state is also a state in which it waits for the PQ switch 74 to be pressed. At this time, for example, the CPU 131 sets L through the LCD driving unit 138.
In the dot display area 71g of the CD 71, a character string "FB" indicating that the date is to be printed on both sides during printing is displayed,
In the dot display area 71h, a character string “'97 representing the date is displayed.
1231 "is displayed (FIG. 9A).

When the photographing is possible, step S
At 11, the CPU determines whether or not the PQ switch 74 has been pressed.
Unless the PQ switch 74 is pressed, the process stays at this step. If the CPU 131 recognizes that the PQ switch 74 has been pressed, the process proceeds to step S12.

In step S13, the CPU 131 determines whether or not the left switch 84 has been pressed. If the CPU 131 recognizes that the left switch 84 has been pressed, the process proceeds to step S14.

In step S14, the CPU 131 sets L
A comment indicating that rewriting of the previous frame of the number of prints is to be performed is displayed on the dot display area 71g of the LCD 71 via the CD drive unit 138, and a character string representing a set value of the number of prints is displayed in the dot display area 71h. P02 "is displayed (FIG. 9D). For example, if the language selected by the photographer is English, the comment is “Data Cha
nge ". If the number of characters of this comment exceeds the number of display digits of the dot display area 71g, the CPU 13
1 preferably scrolls the comment (FIG. 9 (e)), and thereafter displays a predetermined number of characters from the beginning of the comment (FIG. 9 (f)).

At this time, since the operations of the up switch 81 and the down switch 82 are invalid, the upward and downward black triangles are not displayed. On the other hand, the display of the black triangle pointing left before the comment display in the dot display area 71g is
This indicates that the operation of the left switch 84 is effective. In step S15, the CPU determines whether or not the left switch 84 has been continuously pressed for a predetermined time (for example, 2 seconds).
If the CPU 131 recognizes that the left switch 84 has been continuously pressed for a predetermined time or longer, the CPU 131 determines the number of prints,
71 is displayed as shown in FIG. That is,
The CPU 131 sets a character string “P02” indicating the determined new number of prints and a character string “FB” indicating that the date is to be printed on both sides during printing in the dot display area 71g via the LCD drive unit 138. Is displayed, and a date is displayed in the dot display area 71h. Then, the process proceeds to step S16.

In step S16, the previous frame of the number of prints is rewritten. In other words, the data indicating that the previous frame rewriting is to be performed and the number of prints data are transmitted to the CPU 1 of the main body 10 via the communication section 137 of the card 60 and the communication section 110 of the main body 10.
01 is sent. Then, the CPU 101 instructs the film feeding unit 114 to rewind the film by one frame, and then feeds the film by one frame in the forward direction, and at the same time, via the magnetic data writing / reading unit 118. Write the number-of-prints data to the magnetic recording area of the film.
When the previous frame rewriting is completed, in step S17,
The fact that the previous frame rewriting has been completed is notified to the CP of the card 60 via the communication unit 110 of the main body 10 and the communication unit 137 of the card 60.
When notified to U131 and received that the previous frame rewriting has been completed, the CPU 131 resets the number of prints, and in step S18, the CPU 131 causes the LCD 71 to display a date display (FIG. 9 (h)).
