Description

[Detailed description of the invention] (Field of industrial application) The invention is a data recording device for a camera that imprints dates, etc. on film.

(Prior Art) Cameras are generally used to record images, but sometimes it becomes necessary to record not only images but also data attached to the images to be recorded. For example, there are too many to list, such as academic photographs, civil engineering and construction site photographs, medical photographs of X-rays, microscopes, endoscopes, etc., and large quantities of identical or similar objects. It's obvious if you look at it. In addition, further developed requirements include recording photographic data together with images on the photosensitive film surface, such as film sensitivity, exposure time, print value, etc., and when photographing people for identification documents. 2. Description of the Related Art There are cameras that have a function of capturing data related to a person, such as date of birth, height, weight, etc.

In response to such requirements, various methods have been proposed and implemented in the past. For example, data imprinting in X-ray photography is one example, and in the case of even smaller cameras,
It is used to record the set date and time on the film along with the image, or to record the date and time of the shooting along with the image, such as by imprinting the built-in clock dial or digital clock display.

(Purpose of the invention) The present invention has been devised in view of the above circumstances, and consists of a substrate and an electro-optical display element for data imprinting arranged on one surface of the substrate for imprinting data onto a film. a control integrated circuit disposed on the other surface of the substrate; an electro-optical display element for monitoring disposed on the other surface of the substrate overlapping the control integrated circuit; and the other surface of the substrate. It is equipped with a data input section arranged in parallel with the electro-optical display element for the monitor, making it easy to integrate into the limited space of a camera that requires miniaturization, and reducing static electricity caused by the film to the integrated control circuit. The purpose of this invention is to provide a data recording device for a camera that has a structure that does not cause any adverse effects.

Further, the data recording device 4 is connected to the synchronization contact 22 through a signal line 38, but when the shutter release is performed on the camera device 24 side, the data recording device 4 is connected to the data imprinting point 22 built in the data recording device 4, which will be described later. It is provided to obtain a control signal to bring the device into an imprinting operation state.

02 and an imprinting lens that forms an image on the photosensitive material surface from the back side of the film 80 through the imprinting window portion 96. In such a configuration, the human image to be photographed on the film 86 is exposed from the direction of arrow 114 through the photographing lens 10 of the camera device 24, and the data to be imprinted together with the human image is At the same time, the segment of the numerical display element 94 is made to emit light for a time selected and set by the exposure time setting dial 84 of the data recording device 4 shown in FIG. The captured data image is transferred to the projection lenses 100, 10.
4. The image is guided through the reflective prism 102 in the direction of the arrow 116 and imaged and exposed from the back side of the film 86, thereby being imprinted on the film 86 together with the human image.

Furthermore, to explain the structure of the data recording device 4, numeral 40 is a display panel for monitoring the data imprinted on the film surface by the data imprinting device, and is a cold cathode character display tube with 7 segments in the form of a figure 8. Or depending on the light emitting diode character display element etc.26
The screen is configured to display 4-digit numbers for the affiliation code, 2-digit number display for the year of the photo taken, 7-digit number display for the serial number, and 6-digit number for the date of birth. It is equipped with a numeric display section, a 4-digit numeric display section for a person's name code, and a 3-digit numeric display section for height. Numeral 56 is a digital switch for setting semi-fixed data such as affiliation code, year of photography, etc. that does not need to be changed for each photograph, and is comprised of a dial 58 for data setting. (Incidentally, the data set by the digital switch 56 is displayed on the display panel 40 and is also imprinted on the film surface by the data imprinting device at the time of image exposure.) 64 is data. After selecting the function key 66 for setting the shooting serial number using the numerical input keys for setting, by sequentially selecting the keys 64, the counting start number of the shooting serial number is set and the shooting serial number on the display panel 40 is set. After selecting the function key 68 for setting the date of birth, the date of birth data is set by sequentially selecting the keys 64, and the date of birth is displayed on the display panel 40.
