If the main switch 24 is turned on, it is determined whether or not the shutter first stage switch (S ₁ ) 21 is turned on (step 803). If it is turned on, the process proceeds to step 804 and the photographic film is loaded. After displaying the number of sheets, the system waits for the second stage shutter switch 22 (S ₂ ) to be turned on (step 805). When the second stage shutter switch 22 is turned on, the shutter is released (step 806) and exposure is performed. When the exposure is completed, the motor 26a is driven to wind the film and film feeding is started (step 807), and the film feeding display section 32 of the liquid crystal display device 30 lights up to indicate that the film is being fed. (step 808). It is determined whether or not the winding is completed (step 809), and if it is completed, the motor 26a is stopped (step 810).

[0028] Next, the film feed display section 32 of the liquid crystal display device 30 is turned off (step 811). ), the number of shots on the film is counted up (step 812), and then the shutter is It is determined whether the first stage switch 21 is turned on (step 813). The determination in step 813 is to determine whether or not the finger has been released from the release button 15. If the finger is released, the process proceeds to step 814. Ma In addition, if the shutter first stage switch 803 was not turned on in step 803, If not, proceed to step 814.

In step 813, it is determined whether or not the panoramic switch (S _P ) 23 is turned on. If it is turned on, the display segment of the film number display section 31 of the liquid crystal display device 30 is used to display "P" is turned on and used as the panoramic shooting mode display section 36, and the process returns to step 801. If the panorama switch 23 is OFF, the "P" display for the panoramic shooting mode on the film number display section 31 is turned off, the number of films is displayed (step 816), and the process returns to step 801.

[0030] In other words, when in panoramic shooting mode, camera 1 is in standby mode. In some cases, the film number display section 31 indicates that the camera is in panoramic shooting mode with a "P" symbol. The characters are displayed by lighting them up (step 815), and the release button 15 is pressed slightly. The number of films will be displayed when the shutter is pushed in and the first stage shutter switch 21 is turned on. The number of shots of the film is displayed in section 31 (step 804). Therefore, the photographer by checking the liquid crystal display 30 without pressing the release button 15. , if the number of film sheets is displayed, the camera is in normal shooting mode, and the letter "P" is displayed. If it does, you can recognize that you are in panoramic shooting mode.
