The data reading unit 4 is composed of an LED, which is a light emitting element, and a light receiving element (for example, SPC) arranged at a position facing the LED with the film F interposed therebetween. The reading operation is performed while the film F is being fed, and the LED is caused to emit light at a predetermined timing during the feeding of the film to project the light on the film F, and the transmitted light to the opposite side of the film F is received by the SPC. Read. The read data is sent to the printer control unit 6 that controls the printer through the optical data reading unit 5, and the negative image of the photographing frame 1 is printed in the print format corresponding to each read data.

FIG. 3 shows the construction of the film F and the optical data imprinting section loaded in the body of the camera of this embodiment. The film F is pulled out from the cartridge P in the camera and wound on the spool S. The optical data imprinting section 10 is located on the back side (front side) of the film F. The optical data imprinting section 10 is provided so as to face the film F with one light emitting diode (hereinafter, referred to as an LED) 11 that imprints a pattern on the film F from the back side thereof, and is provided on a photographing frame (not shown). The pressure plate (plate member) 12 contacting from the back side, the light blocking plate 13 that blocks the light projected from the LED 11 onto the film F, and the desired pattern is the film F.
It is composed of a format setting lever 14 for moving the light shielding plate 13 so as to be reflected on the upper side.

The pressure plate 12 is provided with a film F from the LED 11.
Two light-transmitting parts 12a, 1 for passing the light projected on
2b is provided so as to face the imprinting position 3 of the film F. The light shielding plate 13 is formed integrally with the format setting lever 14, and by the format setting lever 14,
The state is changed between a state where light passing through all or a part of the light transmitting portions 12a and 12b of the pressure plate 12 is blocked and a state where light is not blocked at all. A knob 14a for operation is formed on the format setting lever 14, and the knob 14a is an opening (15a in FIG. 4) formed in the back cover (15 in FIG. 4).

FIGS. 4 to 6 show the states of the optical data imprinting section 10 when setting each print format.
The optical data imprinting section 10 is arranged on the back cover 15 of the camera. A triangular arrow for alignment is displayed on the knob 14a of the format setting lever 14, and the heads of three types of print format names of high-definition (H), panorama (P), and normal (L) are displayed on the rear surface 16 of the camera. The characters are displayed along the upper end of the knob 14a.

The print format is set in advance by the knob 1 of the print format setting lever 14 at the time of photographing.
This is done by aligning the triangular arrow 4a with the desired print format setting position. The imprint of the pattern related to the print format information on the film F is
It is performed by turning on one LED 11 for a predetermined time (for example, 30 msec) from the completion of exposure after photographing to the film winding. The presence / absence of dots to be imprinted and the number of dots to be imprinted are determined by the two light-transmitting parts 12 a and 12 a of the pressure plate 12.
It is controlled by the positional relationship between b and the light shielding plate 13.

When it is desired to obtain a high-definition print, the triangular arrow of the picking portion 14a is previously aligned with the position of "H" displayed on the rear surface 16 as shown in FIG. At this time, as shown in FIG.

The pattern is imprinted. In this case, the light blocking plate 13
Prevents the light from the LED 11 from passing through the two light transmitting portions 12a and 12b, so that the dot pattern is not printed on the film F.

To obtain a normal print, refer to FIG.
As shown in (b), the triangular arrow of the knob 14a is changed to "L".
To the position of. At this time, as shown in FIG.
Since the light passing through the two light transmitting portions 12a and 12b is not blocked, the light of the LED 11 passes through the two light transmitting portions 12a and 12b and is projected onto the film F. As a result, two dot patterns are printed on the film F.

To obtain a panoramic print, refer to FIG.
As shown in (b), the triangular arrow of the knob 14a is changed to "P".
To the position of. At this time, as shown in FIG. 6A, the light blocking plate 13 blocks light from the LED 11 from passing through the light transmitting portion 12b of the pressure plate 12, but does not block passing through the light transmitting portion 12a. , The light of the LED 11 is the translucent portion 12a.
Only the light passes through and is projected onto the film F. As a result, only one dot pattern is printed on the film F.

In this way, the triangular arrow on the knob 14a of the print format setting lever 14 is set to
Depending on whether the print format setting position is normal or panoramic, the light shield plate 13 may be in a state of blocking light passing through all or a part of the two light transmitting portions 12a and 12b of the pressure plate 12 or in a state of not blocking it at all. Change. Accordingly, one LED 11 can imprint three patterns relating to print format information on the film F. Therefore, it is not necessary to use two LEDs as in the conventional case in order to print the three patterns regarding the print format information on the film F, and a circuit for controlling the turning on and off of these two LEDs is provided. It becomes unnecessary and the cost can be reduced.

The present invention is not limited to the above embodiment, but various modifications can be made without departing from the spirit of the invention. For example, in the present embodiment, the optical data imprinting section 10 is provided on the back cover 15 of the camera, and the pressure plate 12 is provided as a plate member having a plurality of light transmitting sections that allow the light projected from the LED 11 onto the film F to pass therethrough. Use the film F
