(See (d)), respectively. Also, FIG. 2 (b) shows LC
The D display elements 7a to 7h show the finder field during both L and P printing.

FIG. 3 is a circuit block diagram of a camera having the above structure.

In FIG. 3, 5 is a control circuit composed of a microcomputer, 6 is an LCD drive circuit for driving the LCD display elements 7a to 7h, and 8 is a focus of a photographing lens (not shown) in the lens barrel 1. An AF / AE control circuit for controlling the operation of the alignment and exposure control shutter, a magnetic head drive circuit 9 for driving the magnetic head 4, and a film feed motor 10 for driving the film feeding motor (not shown). A film feeding drive circuit 11 performs a remote control reception circuit that receives a signal from a remote control (hereinafter, referred to as a remote control in the description of the embodiments) that can remotely operate the camera.

Reference numeral 12 is a release switch. When this switch is turned on, the camera is released.

Reference numeral 13 is a cartridge loading switch which is turned on when the film cartridge 2 is loaded, and 14 is a back lid switch which is turned on when the back lid is closed, and the control circuit 5 is turned on when these switches are turned on. A signal is input to, and the cueing operation for the first frame of the film is started.

Reference numeral 15 is a switch for setting print to H print, 16 is a switch for setting print to L print, and 17 is a switch for setting print to P print, which is pressed before release. A print format determined by turning on any of these switches is magnetically recorded on the film 3 by the magnetic head 4 through the magnetic head drive circuit 9. As described above, when the switch 15 is turned on, the viewfinder frame is as shown in FIG. 2A, when the switch 16 is turned on, as shown in FIG. 2C, and when the switch 17 is turned on, FIG. It becomes like.

Reference numeral 18 is a remote control mode setting switch, and when the switch 18 is turned on, the control circuit 5 uses the remote control receiving circuit 11 to communicate with an external remote control transmitting circuit described later.

Reference numeral 19 denotes an external remote control transmission circuit, which is the switch 12, 15, 1 for setting the print format.
Print format setting switches 21, 22, 23, and 24 having the same functions as those of 6, 17 are connected.

Next, the operation of the control circuit 5 will be described below with reference to the flowchart of FIG. [Step 101] It is detected whether or not both the switch 13 that is turned on when the cartridge is loaded and the switch 14 that is turned on when the back cover is closed are turned on, and by detecting these ON, the film cartridge 2 is loaded into the camera. Then, assuming that the back cover is closed, the process proceeds to step 102. "Step 102" The film feeding drive circuit 10 is operated to start the operation of positioning the first frame of the film 3 at the aperture portion, that is, the cueing operation. "Step 103" Drive the magnetic head drive circuit 9,
The magnetic head 4 reads the information written in the magnetic storage portion of the film 3, for example, the type of film, the specified number of frames, the ISO sensitivity and the like. "Step 104" It is determined whether or not the first frame of the film 3 is located at the aperture portion. Then, by determining that the first frame has been cued, the feeding of the film 3 is stopped via the film feeding drive circuit 10,
Go to step 105. If the first frame has not been cued, the process returns to step 102 and the same operation is repeated. "Step 105" The switch 18 is turned on to detect whether or not the camera is in the remote control mode. As a result,
If the remote control mode is set, the process proceeds to step 108. If the remote control mode is not set, the process proceeds to step 106. "Step 106" The states of the switches 15, 16 and 17 are detected and the print format is set. As a result, the finder field frame shows the field frame predetermined by the setting of the switches 15, 16 and 17.

Here, when the switch 15 is ON, the control circuit 5 is in the H print format, and the viewfinder field frame is as shown in FIG. Similarly, when the switch 16 is ON, the control circuit 5 sets the L print format and the viewfinder field frame is shown in FIG. Similarly, switch 17 is turned on.
If it is N, the control circuit 5 uses the P print format, and the viewfinder frame is shown in FIG. "Step 107" The release switch 12 is turned on.
It is determined whether or not it has been done, and by turning it on, it is determined that the camera has been released and the process proceeds to step 110.

If the camera is set to the remote control mode in step 105, the process proceeds to step 108 as described above. [Step 108] When the print format setting switches 22, 23, 24 of the external remote control transmission circuit 19 are pressed, the infrared rays from the external remote control transmission circuit 19 are transmitted in the same manner as the switches 15, 16, 17 are pressed. The print format is set by light via communication to the remote control transmission / reception circuit 11. [Step 109] The release switch 12 is passed through the external remote control transmission circuit 19 and the remote control reception circuit 11.
Similarly to turning on, it is determined whether or not the release switch 21 has been pressed, and by determining that the switch 21 has been pressed, it is determined that the camera has been released, and the process proceeds to step 110. "Step 110" The AF / AE control circuit 8 is operated to perform a shooting operation such as an exposure operation by focusing the shooting lens and opening / closing the shutter. "Step 111" For example, by comparing the specified number with the number of releases, it is determined whether or not there is a remaining frame on the film 3, and if there is, the process proceeds to step 115. If there is not, the shooting of the specified number of frames is completed. If so, the process proceeds to step 112. "Step 112" The film feeding drive circuit 10 is operated to start winding the film 3. "Step 113" The magnetic head drive circuit 9 is driven to move the magnetic head 4 to the magnetic storage portion of the film 3 during film winding in the print format set in step 106 (or step 108) or in step 110. Information such as shutter speed and aperture value during shooting is recorded. "Step 114" Whether or not the winding of one frame is completed is determined by a known means, for example, a method of detecting the rotation amount of a sprocket (not shown) or by counting the perforations of the film 3 by a photo sensor, and then the operation is completed. If not, the process returns to step 112. When it is determined that the film 3 is finished, the film 3 is stopped to be fed through the film feeding drive circuit 10, and the process returns to step 105.

If it is determined in step 111 that the shooting of the specified number of frames has been completed, the process proceeds to step 115 as described above. "Step 115" The film feeding drive circuit 10 is operated to start the rewinding of the film 3. "Step 116" The magnetic head drive circuit 9 is driven to cause the magnetic head 4 to move to the magnetic storage portion of the film 3 during film rewinding, step 106 (or step 108)
Information such as the print format set in step 1 and the shutter speed at the time of shooting performed in step 110 and the aperture value is recorded. That is, the recording of information on the last frame is performed when the film is rewound. "Step 117" Whether or not the film rewinding has been completed is determined by a known means, and the series of operations is completed by ending it.
