Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for printing photographed data on film.

[0002]

2. Description of the Related Art Various devices have been proposed and put into practical use as devices for printing photographing data such as aperture value, shutter speed, photographing date and time on a silver salt film. However, conventional products are generally those in which data is imprinted from the back side of a 35 mm film made of a transparent base material, and a backing paper is used.
Not applicable to Brownie film. Theoretically, it is possible to imprint data from the front side in the same way as from the back side of the film, but when actually arranging the data imprinting device at the front side of the film, it is difficult in terms of space. Occurs. Therefore, there was no camera capable of imprinting data on 120 Brownie film.

Further, the conventional data imprinting device is in a fixed position, and the distance from the film changes depending on the condition of the film. Therefore, there is a problem that the imprinted data becomes unclear when the distance from the film increases.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a device for imprinting data from the front side of a film, which has less space restrictions. Another object of the present invention is to obtain a data imprinting device that can always imprint clear data on a film.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a light irradiating section having a plurality of light emitting dots arranged in a direction substantially orthogonal to the moving direction of a film is provided so as to face a front surface of a film moving surface, and the light irradiating section is provided at an arbitrary position of a camera body. , Providing a data module having LEDs corresponding to each light emitting dot of the light irradiating section, guiding the light of each LED of this data module to each light emitting dot via the corresponding optical fiber, and further synchronizing with the running of the film. A plurality of LEDs of the data module are selectively made to emit light, and a light emission control device is provided in the data recording portion of the film in the form of a matrix to capture the photographing data. According to this configuration, only the irradiation unit needs to be arranged on the front side of the film, and the date module can be installed away from the film surface, so that the problem of space can be solved.

It is preferable that the light irradiating section is movable in the thickness direction of the film and is urged to move in the direction of contact with the film. By doing so, the light irradiation section and the film can be constantly brought into contact with each other, and clear photographing data can be photographed.

According to the present invention, photographing data can be recorded on a film having a backing paper such as 120 Brownie film, 220 Brownie film, 35 mm
The same can be applied to a camera using a film using a transparent substrate such as a film.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to illustrated embodiments. In the camera body 11, a take-up spool chamber 13 is provided on one of the left and right sides of the photographing opening 12, on the left side in FIG. 1, and a film chamber (not shown) is provided on the right side. The silver salt film F stored in the film chamber is the winding spool chamber 1
It is wound up on the take-up spool 14 in 3.

In the camera body 11, an advancing / retreating hole 17 located in front of the film F is formed in an upper portion between the photographing opening 12 and the winding spool chamber 13 so as to be located between the inner rail 15 and the outer rail 16. The light irradiation part 20 is supported in the advancing / retreating hole 17 so as to be capable of advancing / retreating in the direction of approaching / separating from the film F. As is well known, the inner rail 15 and the outer rail 16 are provided above and below the photographing opening 12, and the pressure plate 18 abuts on the outer rail 16, and the film F is interposed between the pressure plate 18 and the inner rail 15. A tunnel space that passes through is formed. The pressure plate 18 includes a leaf spring 2 on the camera back cover 19.
It is supported through 1.

A plurality of light irradiation units 20 (seven in the illustrated example)
The light emitting dots 22 are arranged in a line in a direction substantially orthogonal to the moving direction on the surface facing the film F, and are urged to move toward the film F by the leaf spring 24. One end of the leaf spring 24 is fixed to the camera body 11 by a fixing screw 23.

On the back cover 19, the film F is sandwiched, and the film pressing roller 2 is provided at a position facing the light irradiation section 20.
5 are provided. This film pressing roller 25
The leaf spring 26 is supported by one end thereof, and the other end of the leaf spring 26 is fixed to the back cover 19. Due to the force of the leaf spring 26 and the leaf spring 24, the light irradiation section 20 is always reliably brought into contact with the front surface of the film F.

A data module 27 is fixed to the camera body 11 with fixing screws 32. In the illustrated example, the data module 27 is fixed to the front side portion of the take-up spool chamber 13 for the sake of convenience of illustration, but can be arranged at any place where space can be easily taken.
This data module 27 includes a substrate 29 on which LEDs 28 corresponding to the number of light emitting dots 22 are fixed, and a substrate 29
And a cover 30 fixed on the cover 30.
A recess 31 that receives each LED 28 and prevents the entry of other light.
Are formed. The upper portion (bottom portion) of the recess 31 and each light emitting dot 22 of the light irradiation unit 20 are connected by a flexible optical fiber 33, and the LED 28 is connected.
Light is guided to the light emitting dots 22.

Each LED 28 of the data module 27 is
The light emission control circuit 35 controls the light emission. The light emission control circuit 35 is supplied with data from a pulsar 36 that generates a pulse according to the progress of the film F and a photographing data holding circuit 37. Pulsar 36 is film F
It is a well-known one composed of a light-shielding disc 40 provided coaxially with a counter roller 39 that rotates in frictional contact with the photocoupler 41 and a photocoupler 41, and generates a pulse in synchronization with the traveling of the film F. Reference numeral 42 in FIG. 1 denotes a focal plane shutter,
A photographic lens (not shown) is provided below the photographic aperture 12 in FIG. In the illustrated example, the LEDs 28 on the substrate 29 are arranged linearly, but it is not necessary to arrange them linearly.

Therefore, the present apparatus having the above-mentioned structure operates as follows. When the photographing of one frame is completed, the photographing data at that time, for example, the F value, the shutter speed, the photographing date and the like are stored in the photographing data holding circuit 37. After the filming of one frame is completed, when the film F is wound up, the counter roller 39 that is in frictional contact with the film F is rotated, and the pulser 36 generates a pulse. The light emission control circuit 35 controls each LED 28 to blink according to the pulse from the pulser 36 and the photographing data stored in the photographing data holding circuit 37, and the data recording portion of the film F, that is, the upper side of the film in the illustrated example. Photographed data is recorded in a matrix on the lower side of the photographed image. FIG. 4 shows an example of the recording form.
An example in which “F11” is recorded by the film advancing direction A and the dot data in the D direction given to the seven light emitting dots 22 orthogonal to the A direction is shown.

As described above, the present invention can be applied regardless of the type of the film F, but as shown in FIG. 2, it can also be applied to the 120 Brownie film in which the backing paper p is located on the back surface of the film F. This is one of the features.

[0016]

As described above, according to the present invention, since the photographed data can be imprinted from the front side of the film, it can be used as a data imprinting device for 120 Brownie film having a backing paper. Since the light irradiator and the data module are connected by the optical fiber, the data module can be arranged at a portion apart from the film surface, which causes a space problem when the data imprinting device is provided on the front side of the film. Can be resolved. According to the second aspect, it is possible to record the clear photographed data image in the film recording unit by constantly contacting the light irradiation unit with the film.
