Entered in. A film winding signal is output from the sequence control circuit 60 to the film driving circuit 66, and the film is wound. The film feed amount detection circuit 71, which detects the rotation of the detection roller 50, supplies the film feed amount to the film counter circuit 70 which has been reset in the state before the film is loaded (the film is not loaded and the case back 32 is opened). The number of pulses shown is input, and film winding at the initial load is counted. When the winding is completed, a winding completion signal is input to the sequence control circuit 60, and the sequence control circuit 60 outputs a winding stop signal to the film drive circuit 66 to stop the film winding. At this time, the film count of the display circuit 79 is set to 1.

The operation at the time of shooting will be described. Shatter Tallery
When the zoom button 42 is pressed down by the first step, the photometric circuit 61 operates, and the subject brightness signal is input to the sequence control circuit 60. When the shutter release button 42 is pressed to the second stage, a release signal is input from the release signal generation circuit 62 to the sequence control circuit 60. At this time, if the subject brightness is equal to or higher than a predetermined level, the sequence control circuit 60 outputs the AF signal.
A shooting lens drive signal is output to the circuit 64, and focus adjustment is performed. When the subject brightness is equal to or lower than a predetermined level, it is confirmed that the flash circuit 65 has output the charge completion signal, and then the photographic lens drive signal is output to the AF circuit 64 for focus adjustment.

When the AF circuit 64 outputs a focus adjustment completion signal, the sequence control circuit 60 outputs an exposure control start signal to the AE circuit 63 to perform exposure control (photographing). At this time, when the subject brightness is below a predetermined level, a light emission start signal is output to the flash circuit 65.

When the exposure control (shooting) is completed and the exposure control completion signal is input from the AE circuit 63 to the sequence control circuit 60, a shooting lens return signal is output to the AF circuit 64, and the shooting lens 40 is turned on. Return to the initial position. Shooting lens 40
When the backward movement is completed, the backward movement completion signal is output and input to the sequence control circuit 60. At this time, when the film detection circuit 68 outputs a signal indicating that the film has not been mounted, the photographing operation ends, but when the signal indicating that the film has been mounted is output, the sequence control circuit 6
A film winding signal is output from 0 to the film drive circuit 66 to start film winding. The film counter circuit 70 receives as many pulses as the film feed amount from the film feed amount detection circuit 71 which detects the rotation of the detection roller 50, and counts the film winding for one frame. When the winding is completed, a winding completion signal is input to the sequence control circuit 60, and the sequence control circuit 60 outputs a winding stop signal to the film drive circuit 66.
The film winding is stopped, the film count of the display circuit 79 is incremented by 1, and the standby state is entered.

The storage of the imprinted data and the data imprinting operation will be described. When the exposure control completion signal is input from the AE circuit 63 while the film detection circuit 68 outputs a signal indicating that the film is mounted to the sequence control circuit 60, the sequence control circuit 60 causes the sequence control circuit 60 to print the image. A data storage circuit 72 is instructed to store data, the count number counted by the film counter circuit 70, and photographing information set in the data setting circuit 73, such as photographing date and time, film sensitivity, Information on the photographing mode set in the P / N switching circuit 77 (whether normal photographing mode or panoramic photographing mode) and the data imprinting position on the film set by the imprinting position setting circuit 20. Etc.
The data is stored in the data storage circuit 72. The above-described storage operation of the shooting information is performed every time one frame is shot.

When the film end is detected by the film end detection circuit 67 during film winding after photographing the last frame, a detection signal is input to the sequence control circuit 60. The sequence control circuit 60 outputs a rewind signal to the film drive circuit 66 to start rewinding the film. The detection roller 50 rotates in the reverse direction, and the number of pulses indicating the film rewinding amount becomes a film feed amount detecting circuit 71.
And the contents of the film counter circuit 70 are subtracted.

The rewinding signal output from the sequence control circuit 60 is also input to the data imprinting control circuit 75 to enter the operating state. When the contents of the film counter circuit 70 are input to the data imprinting control circuit 75 and a signal indicating the leading end of the rewinding direction of one photographic frame is obtained, photographic information and photographic mode information relating to the corresponding photographic frame. , And the data imprinting position information is read from the imprinting data storage circuit 72 to activate the image frame imprinting light projecting unit 43, and the photographing information based on the data imprinting position information on the corresponding photographing frame,
Further, when the panoramic shooting mode is set as the shooting mode, the panorama image frame is imprinted.

For example, if it is assumed that the panorama shooting mode, the film sensitivity ISO100, the shooting date / time data, and the imprinting position are read out from the imprinting data storage circuit 72 as the photographing information of the fifth frame. , The rewinding of the film is started, and the fifth frame is the light emitting diode row 46a, 46b.
When passing in front of, the data imprinting control circuit 75 controls the position on the basis of the imprinting position information while controlling the blinking of the light emitting diode rows 46a and 46b to imprint it on the photographing information film. Further, since the panoramic photography mode is recorded on the fifth frame, the light emitting diode row 46a,
All of the light emitting diodes 46a and 46b in a position corresponding to the outside of the panoramic image frame in 46b are turned on, and the entire outside of the panoramic image frame is exposed to expose the panoramic image frame on the photographing screen.

When the panoramic image frame is imprinted, the light quantity of the light emitting diode should be increased more than in the case of imprinting photographing information so that the exposure sensitivity is overexposed to the film sensitivity (for example, ISO100). With, you can finish the outside of the panoramic image frame white on the print.

Instead of increasing the light quantity of the light emitting diode, the light quantity of the light emitting diode may be kept constant and the rewinding speed of the film may be slowed only in the panoramic photographing mode. Further, the power check circuit 80 detects the remaining amount of the power battery, and when the remaining amount of the power battery is sufficient, the light amount of the light emitting diode is increased without changing the film rewinding speed. When the remaining amount of the battery is not sufficient, the light amount of the light emitting diode may be kept constant and the rewinding speed of the film may be slowed down.

When the panoramic image frame is imprinted, it is possible to imprint the photographic information such that only the photographic information such as the photographic date and time to be imprinted is not exposed or only the photographic information is properly exposed. Further, in the panorama shooting mode, a character indicating that the panorama shooting is performed may be imprinted as one piece of shooting information.
