The module 3 is a board on which a circuit for controlling the data imprinting module 2 is mounted, and the reference numeral 4 is a flexible board for connecting the data imprinting module 2 and a circuit on the board 3.

As shown in FIGS. 1 and 2, a light emitting unit 5 for imprinting the photographing date and time is projected from a data imprinting module 2 integrally formed of resin, and a perforation FP of a film F is detected. Detecting perforation detector (photoreflector) 6 and PAR

As shown in FIG. 3, the data imprinting module 2 is attached to the rear side of the camera of the pressure plate 10, and the light emitting portion 5 is provided in the opening 10A formed in the pressure plate 10, the LED 7 is provided in the opening 10B, Each is stored.

The film F is fed by a perforation F
P is detected and controlled. When a film feeder (not shown) feeds the film F and the perforation FP faces the perforation detector 6, the light emitted from the perforation detector 6 emits light.
(See FIGS. 1 and 2). This light is reflected by a reflection surface (not shown) provided with the film F interposed therebetween, and reenters the perforation detector 6. Since the reflection surface is set to have a higher light reflectance than the surface of the film F, the perforation FP is detected by detecting an increase in the amount of light received by the perforation detector 6. Since the start and stop of the film feeding are controlled based on the timing of the detection of the perforation FP, the feeding of the film F is appropriately performed.

Data imprinting is performed with the film F stopped at an appropriate position. After the feeding of the film F is stopped, the photographing date and time are imprinted from the back side of the camera into the print area of the film F by causing the light emitting unit 5 to emit light.
Light emitted from the rear side of the camera reaches the emulsion via the base of the film F.

PAR imprinting is performed by causing one or two of the two LEDs 7 to emit light in accordance with the PAR arbitrarily selected by the photographer. In the first embodiment, data imprinting is performed. And PAR imprinting are performed simultaneously.

Although FIG. 4 shows a case where two LEDs 7 emit light, the PAR of each photographed frame can be determined according to a combination of whether or not each LED 7 emits light. For example, at the time of development, PAR determination is performed based on the pattern of the exposure unit 11 formed by PAR imprinting.

In the first embodiment, since the perforation detector 6 and the LED 7 are mounted on the data imprinting module 2, a dedicated control board for each of the perforation detector 6 and the LED 7 is not required, and the connection is simplified. Thus, the weight and cost of the camera can be reduced. In the first embodiment, since the PAR imprinting and the data imprinting are performed simultaneously, the imprinting operation is completed only by stopping the feeding of the film F once. Therefore, the time required until the next frame can be photographed can be reduced, and the control of the imprinting operation can be simplified. The time for PAR imprinting and the time for data imprinting may be the same, or may be different exposure times. For example, only the start or end of imprinting may be performed simultaneously.
