Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data imprinting device for imprinting date and time data on a photographed film, and particularly to a photographed film by automatically inputting photographing date and time data from a film with a lens capable of storing the photographing date and time. The present invention relates to a device for imprinting date and time data.

[0002]

2. Description of the Related Art A camera having a function of imprinting a shooting date and time is already on the market and is publicly known. As a method of imprinting the shooting date and time on this type of camera, for example, the date and time information is imprinted on the already photographed frames at the time of film winding, which is performed after the frames have been photographed. Therefore, a date / time imprinting mechanism is required for each camera.

On the other hand, a camera called a film with lens is provided. This type of camera is characterized by simple handling and low price. Since the date and time imprinting mechanism is relatively expensive, providing this mechanism on the film with lens leads to an increase in the price of the main body. Therefore, a lens-attached film having a date and time imprinting function has not been provided yet.

An invention relating to an apparatus for imprinting desired data on a film is disclosed in Japanese Patent Publication No. 62-51456. An example of the present disclosure will be described with reference to FIG. 3. Figure 3
FIG. 3 is a block diagram of a data imprinting device according to the disclosed example. The data imprinting device according to the disclosed example includes a data input unit 50, a data storage unit 51, a frame number detection unit 52, a data reading unit 53, a display unit 54, an imprinting unit 55, and a release switch 56. The operation of the data imprinting device thus configured will be described below.

The number-of-frames detector 52 designates the number of frames to be photographed next to the number of frames photographed. The data input from the data input section 50 is stored in the area of the data storage section 51 corresponding to the shooting frame number designated by the frame number detection section 52. By continuously inputting data, it is possible to store different data in advance in the area corresponding to consecutive frame numbers.

The data reading section 53 reads the data of the area corresponding to the photographing frame number designated by the frame number detecting section 52 from the data storing section 51 and supplies it to the display section 54 and the imprinting section 55.

When the release button of the camera is pressed, the release switch 56 is closed, and the imprinting section 56 imprints the data supplied from the data reading section 53 on the film 57 together with the subject. The release switch 56 may not be interlocked with the release button of the camera, but may be closed after the subject is imprinted and the data may be imprinted.

[0008] Such an apparatus is suitable for the case where the related data is simultaneously photographed at the time of photographing an object whose photographing target is known in advance, such as an endoscope camera.

[0009]

When the date and time imprinting function is provided on the lens-equipped film, the main body price becomes expensive, and the greatest feature of low cost is lost.

On the other hand, according to the disclosed example shown in FIG. 3, it is possible to imprint data every time one frame is photographed. However, it is difficult to imprint the date on the photographed film wound on the patrone after photographing on all the photographed frames because of problems such as alignment of the photographed frames.

It is difficult for the film with a lens to be provided with a date / time imprinting device because of price restrictions. In addition, normally, data such as the date and time to be imprinted with the subject is not determined until the time of photographing.

An object of the present invention is to provide a data imprinting device capable of reading out the photographing date / time data from a film with a lens capable of storing the photographing date / time data and imprinting the photographing date / time data on each photographing frame of the photographed film. It is to be.

[0013]

A data imprinting device of the present invention comprises interface means for inputting data corresponding to a photographing frame from an external storage device, and storage means for storing data corresponding to the photographing frame. A film driving means for driving the loaded photographed film, a film state detecting means for detecting a traveling distance of the film, and an imprinting means for imprinting data on the film.

[0014]

The photographing data is transferred from the external storage device such as the film with lens having the date and time storage device to the storage means through the interface means and corresponds to each photographing frame aligned by the film driving means and the film state detecting means. By imprinting the photographing data to be photographed by the photographing means, it becomes possible to collectively photograph the photographing data onto the photographing frame of the photographed film.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A data imprinting apparatus according to an embodiment of the present invention will be described below with reference to FIG.

FIG. 1A is a block diagram of a data imprinting apparatus according to this embodiment, and FIG. 1B is a perspective view. The interface means 1 is connected to the lens-attached film 10, receives the photographing date / time data for each photographing frame, and transfers it to the control means 9. At this time, as shown in FIG. 1B, the lens-equipped film 10 is fixed by the positioning stopper 11, and the interface means 1 and the connection terminals of the lens-equipped film 10 are connected.

The storage means 2 stores the date and time data for each photographing frame input from the interface means 1. The storage means 2 is, for example, DRAM, SRAM, EEPROM,
It can be composed of a semiconductor memory device such as a latch. At the time of imprinting the date and time data, the date and time data corresponding to the corresponding photographing frame number is read out by the instruction from the control means 9 and transferred to the control means 9.

The film driving means 4 loads a film having been photographed, winds the film, rewinds it, and aligns the frame. The film driving means 4 used in this embodiment is equivalent to the film driving section of a normal camera.

The film state detecting means 5 detects the loading state of the film, the winding state, the rewinding state, and the length of the film running, and notifies the control means 9 of the detected state. Imprinting means 3
Is equivalent to a normal camera date / time data imprinting device including a lamp and a liquid crystal display element. Imprinting means 3
Receives the imprinting instruction signal from the control means 9 and imprints the instructed date and time data.

However, in general, the loading direction of the film is reversed between the lens-equipped film and the ordinary camera. That is,
The upper and lower images are reversed in the film shot with the lens-equipped film and the film shot with the normal camera. For this reason, the date / time imprinting section is arranged in the upside-down position of the normal camera. The imprinting means 3 receives the imprinting instruction signal from the control means 9 and imprints the instructed date and time data.

As the imprinting unit 3, the film driving unit 4, and the film state detecting unit 5, for example, a camera body having a simultaneous imprinting function can be used. Figure 1
In (B), the imprinting mechanism 14 shows such a functional member.

The input means 6 is composed of a function key for inputting an operation instruction and a numeric keypad for inputting date and time data and the like. The input information is the control means 9
Transferred to.

The display means 7 displays the shooting frame number and date / time data stored in the storage means 2, displays the shooting frame number and date / time data input from the input means 6, and displays the next operation instruction. . Although a liquid crystal element is used in this embodiment, other display elements can be used.
For example, light emitting diodes, CRT displays, etc. may be used.

The warning means 8 displays a message such as "imprinting of date and time" and "imprinting of date and time". In this embodiment, a light emitting diode is used. Other display elements may be used similarly to the display means 7. It can also be used as the display means 7.

The control means 9 controls each process such as input of date and time data, film winding, rewinding, and date and time data imprinting. The data imprinting apparatus according to this embodiment is composed of a microprocessor and a memory.

A method of imprinting date and time data using the data imprinting apparatus thus configured will be described below. FIG. 2 is a sequence diagram showing steps from the end of photographing to the end of imprinting of date / time data.

As shown in step B1, when the power switch of the data imprinting device is turned on, "C" is displayed on the display means 7.
“Omand” is displayed, and the command input is awaited.
The time change key of the input means 6 is pressed. “Input Date” is displayed on the display means 7, and the date and time information input waits. As shown in step B2, the current date and time are input from the ten keys of the input means 6. For example, if it is 13:30:30 on May 15, 1993, enter 930515133330CR. Here, CR is a terminator key for notifying the delimiter of data and represents the end of input data.

Next, the time display key is pressed. The current date and time are displayed on the display means 7, which is confirmed. If the displayed date and time are different from the current date and time, the time change key is pressed again to correct the date and time.

When the displayed date and time are correct, the command input key is pressed. "C
“Omand” is displayed, and the command input is awaited.
The film with lens has a clock signal generator, a counter, and a memory. The counter counts the elapsed time from a certain time. As shown in step A1, when shooting is performed, the count at the time of shooting is recorded in the corresponding area of the memory. If you compare the current count and the count at the time of shooting,
You can know the date and time of shooting.

The connection terminal of the film with a lens that has been taken,
As shown in step A2, it is connected to the interface means 1 and fixed by the positioning stopper 11. The data read key of the input means 6 is pressed. The LED of the alarm means 8 during data transfer is turned on, and as shown in step B3, the date / time data (shooting date / time data tn) corresponding to each image frame recorded on the film with lens is controlled via the interface means 1. 9 is transferred. The transferred shooting date / time data tn is stored in the storage area of the storage unit 2 corresponding to the shooting frame. When the transfer of the date and time data corresponding to all the shooting frames is completed, the count (current date and time data tl) corresponding to the current date and time measured in the film with lens is transferred and stored in the corresponding storage area of the storage area 2. To be done.

Photographing date / time data tn used in this embodiment,
The current date / time data tl is the value of the date / time counter in the film with lens. The date and time counter is initially set at the time of factory shipment of the film with lens and is incremented every hour. Therefore, in order to obtain the absolute date and time TN at which the image was taken, first, the difference between the current date and time data tl and the image date and time data tn is calculated.

This difference is a relative value of the shooting date and time based on the current date and time. By returning this relative value from the current date and time input in the above process, the date and time data shown in step B4 can be converted to obtain the absolute date and time TN at which the image was taken. The date / time data conversion may be performed anywhere before the date / time data is imprinted.

In the present embodiment, the case where the film with lens has a simple date and time counter that counts up every hour has been described. However, the film with lens has a built-in clock for obtaining an absolute time, and photographing is performed. The absolute date and time of the operation may be stored. In this case, it is not necessary to transfer the current date / time data tl and calculate the shooting date / time TN based on the current date / time as described above.

When the data transfer is completed, "Command" is displayed on the display means 7, and the alarm means 8 is transferring L
The ED goes out. Next, press the data display key. The display unit 7 displays the shooting data corresponding to the shooting frame number 1 and the first shooting frame. For example, when the shooting date and time of the first image is January 8, 1993, “No. 01 93
01/08 ”is displayed. By pressing the increment key of the input means 6, the shooting date and time corresponding to the next shooting frame is displayed. By pressing the decrement key, the shooting date and time corresponding to the previous shooting frame is displayed. In this embodiment, the increment key and the decrement key are assigned to the numeric keys “2” and “8” of the input means 6, respectively.

The imprint date and time may be corrected by pressing the imprint date and time correction key when the photographing date and time corresponding to each image frame is displayed. If data confirmation is not necessary, this data confirmation step may not be executed.

When the confirmation and correction of the photographing date / time data are completed, the command input key is pressed. "C
“Omand” is displayed, and the command input is awaited.
The film with lens is removed from the interface means 1 and the positioning stopper 11, and the film having been photographed is taken out. Since the leading edge of the film that has already been taken is usually caught in the cartridge, pull out the leading edge with a film picker. As shown in step B5, the photographed film having the leading end pulled out is loaded into the film driving means 4, the leading end of the film is aligned with a predetermined position, and the back cover is closed.

The data write key of the input means 6 is pressed.
The LED is turned on while the alarm means 8 is being printed, and the film driving means 4 automatically winds the film. When the winding is completed, the rotation direction is reversed and the first frame is rewound.

The film contained in the lens-equipped film is wound up at the time of shipment from the factory and then rewound by a fixed length. Therefore, the position of the first frame can be accurately aligned by the above operation.
When the film is rewound, the film state detecting means 5 can rewind the film by a desired length by counting the number of percolations opened in the film.

When the positioning of the photographic frame is completed, the control means 9 reads the photographic date / time data corresponding to the photographic frame stored in the storage means 2. An imprinting instruction signal is sent to the imprinting means 3. The imprinting means 3 receives the imprinting instruction signal and imprints the date and time data as shown in step B6.

It should be noted that the absolute date and time when the image was taken is obtained in advance by the method described above (step B4), and the absolute date and time is stored in the storage means 2.
Instead of storing the relative date and time in the storage means, the relative date and time may be stored in the storage means and calculated immediately before the imprinting.

When the imprinting is completed, the film driving means 4 operates to rewind the film for one frame. The imprinting step and the film rewinding step are repeated for the number of film frames. When the printing of all the frames is completed, the film driving means 6 rewinds the film into the patrone. When the rewinding is completed, the imprinting LED of the alarm means 8 is turned off and the imprinting end LED is turned on.

After the imprinting completion LED is turned on, the back cover of the film driving means 4 is opened as shown in step B7.
Take out the film. When the film is taken out, the imprinting end LED of the alarm means 8 is turned off and the display means 7 displays “Co
“Mand” is displayed, and the command input is awaited. The film taken out proceeds to the developing process in step B8.

As described above, by using the imprinting apparatus according to this embodiment, there is no date and time imprinting function,
Shooting date and time data can be imprinted on a film that has been shot with a lens-equipped film having a date and time data storage function.

The present invention has been described above with reference to the embodiments.
The present invention is not limited to these. For example,
It will be apparent to those skilled in the art that various changes, improvements, combinations and the like can be made.
