Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a photographic machine.

[Conventional technology]

As is well known, a camera projects an image of a subject onto film, which is a photosensitive material.The image projected onto this film is developed to obtain a negative, which is then printed onto photographic paper to create a print.
In other words, what is usually called a photograph is obtained.

By the way, photographs are often saved as records of travel and other events, and the date of the photograph is often recorded as date data of the trip. A date counting means and a projector are incorporated, and the date of the photograph counted by the counting means is projected onto the film by the projector, and numbers indicating the date are placed in the corners of the photograph as an image of the subject. I try to bake them together.

[Problem to be solved by the invention]

In this way, the only data that is printed on the photo is the shooting date, so for example, if multiple rolls of film are used on the same day, the same date will be printed on each film as data. The order of the films to be used cannot be determined from this data, and when organizing photos later, the order of the films to be used is determined by the photographer's memory, which is not only troublesome, but can also lead to mistakes in the order.

In addition, the order in which the photographs were taken cannot be determined from the photographs printed on a single film, and the only way to determine this is to compare the photographs one by one with the negatives, which is of course useful when sorting. However, when reprinting a photograph, it is necessary to find the frame corresponding to the photograph from a long film, which is troublesome.

The purpose of the present invention is to solve the above-mentioned disadvantages of the conventional example, so that when multiple films are used on the same day, the number of each film used can be seen at a glance, and it is also possible to print on each film one by one. Just by looking at the photo, you can change the order of the frames from the photo,
The purpose is to provide a camera that allows you to see the order of shooting at a glance, and allows you to easily organize and reprint photos.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a means for counting film numbers and frame numbers, and a projector for projecting the film number and frame number onto the film in response to the output from the counting means. That is.

(Function) According to the present invention, the number of used films is counted by the counting means, and the used film number is projected onto each frame of the film by the projector and printed on the photograph. At the same time, the number of frames on each film is counted by a counting means, and a frame number is projected onto each frame of the film by a projector and printed onto a photograph. Therefore, when using multiple rolls of film on the same day, by projecting a continuous film number onto each film, you can not only check the order of the films used, but also identify the photo printed with this film number. Understand the order of film, frames, and shooting order.
