Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera with a data imprinting device, and in particular, it is possible to imprint a plurality of lines of data in an area between film photographing screens and to adjust the interval between the photographing screens. About the camera you did.

[0002]

2. Description of the Related Art For example, there is a demand for recording data relating to the contents of photographing on a film at the time of photographing when recording for academic purposes or experiments and copying materials.

As a method of imprinting data on a film, a camera imprinting a date or the like on a photographed screen has been conventionally used. However, such a method is not suitable for imprinting a large number of data because a part of the photographed image is erased by imprinting the data and the photographed image becomes extremely difficult to see.

For this reason, there is known a camera having a function of imprinting data on a portion between film photographing screens (hereinafter referred to as a frame interval) (Japanese Patent Laid-Open No. 1-26).
3633). With such a camera, it was possible to imprint data without affecting the captured image.

[0005]

However, in such a conventional camera in which data is imprinted between frames, the number of frames that can be photographed by a camera without a data imprinting device, that is, the film can be nominally photographed. Since the unity of the number of frames is emphasized, the data was recorded with the width between the frames being narrow (2 mm) as in the case of the camera without the data recording device. For this reason, such a conventional camera has a disadvantage that data can be imprinted only on one line.

In order to solve such an inconvenience, it is considered that a plurality of lines of data are imprinted between the frames. However, in order to imprint a plurality of lines of data between the frames, a large distance between the frames must be taken. If the imprint data amount differs for each frame, the distance between frames becomes unstable.

This causes a discrepancy in the lengths of the cut pieces, especially when a plurality of image frames are separated from each other and stored in a case such as a negative film. 38mm x 6 frames = 2
When attempting to store a 28 mm cut piece in a predetermined case that can store the cut pieces, one film cannot be stored in one case, which is wasteful and inconvenient to handle.

In addition, a perforation hole is formed at a regular interval in a 35 mm film that is usually used, and if the film cutting position overlaps with the perforation hole because the data is imprinted between the frames, the above-mentioned storage case The film is apt to be caught in the storage opening, which causes a problem that it takes a lot of time to store the film.

The object of the present invention is to solve such a problem, and enables the printing of a plurality of lines of data between the frames of the film and the adjustment of the interval between the photographing screens. To provide a camera with the data imprinting device.

Another object of the present invention is to adjust the distance between frames so that the perforation holes of the film and the film cutting position do not overlap in a camera capable of imprinting a plurality of lines of data between the frames of the film. Is to

[0011]

In order to achieve the above object, according to the present invention, there is provided a camera with a data imprinting device for imprinting data in a region between the photographing screens of a film, The camera comprises a projection head disposed near the front end or the rear end of a photographing aperture section that defines the screen area of the film, and film winding capable of screen feed of the film and small feed for image transfer. And a means for imprinting a plurality of lines of data and adjusting an interval between photographing screens.

Further, it is preferable that a setting means for setting the interval between the photographing screens is provided, and the interval can always be set to a constant value by the setting means irrespective of the amount of imprinted data.

Further, when n is an integer of 1 or more, the front end or the rear end of the nth frame of the photographing screen, and when m is an integer of 1 to 6, the front end of the n + mth frame of the photographing screen. Alternatively, it is convenient to set the distance from the rear end portion to a predetermined amount, for example, approximately 288 mm.

Further, the film has perforation holes, and a hole detection means for detecting the position of the perforation holes of the film is provided, and an output of the hole detection means is used to detect a front end or a rear end of the photographing screen between the perforation holes. It is also possible to adjust the photographing screen interval so as to be separated from the center by a predetermined distance. In this case, the distance from the data line farthest from the shooting screen corresponding to the data in the imprinted data to the edge of the adjacent shooting screen is
It is convenient to adjust the shooting screen interval so that it is always a predetermined value or more regardless of the amount of imprinted data.

Further, a warning means for warning the excess of the imprint data amount is provided, and the warning means is activated when all the imprint data cannot be imprinted in the interval between the photographing screens set by the setting means. It can also be configured.

Also, film information setting means, film length calculating means for calculating the film withdrawable amount based on the film information obtained from the film information setting means,
It is convenient to provide winding-up length calculating means for integrating the film winding amount to calculate the wound-up film amount, and display means for displaying information on the number of film frames by using the output of each of these calculating means.

In this case, the film information setting means may be film information detecting means such as DX code detecting means.

[0018]

In the camera having the above structure, the data is imprinted by the imprinting head disposed near the front end or the rear end of the photographing aperture portion that defines the screen area of the film, and the film is wound in small increments by the film winding means. Multiple lines of data are imprinted. Further, by adjusting the winding amount of the film winding means, it is possible to adjust the interval between the photographing screens.

When the setting means for setting the distance between the photographing screens is provided, if the distance between the photographing screens is set by the setting means, the distance is always a constant value regardless of the imprint data amount. Can be set to. As a result, the distance between the frames becomes constant and the film is easily handled. Also, the distance between the front end or the rear end of the nth frame of the photographing screen and the front end or the rear end of the n + mth frame of the photographing screen is set to a predetermined amount, for example, 228 mm. The same length of film can be efficiently stored in each storage stage of the existing film storage case, which is convenient for film organization.

When the film has perforation holes, the front end or the rear end of the photographing screen is separated from the center of the perforation holes by a predetermined distance by using a hole detecting means for detecting the position of the perforation holes of the film. When the screen interval is adjusted, the cutting position does not overlap the perforation hole when the film is cut at the front end or the rear end of the shooting screen. Further, in this case, the interval from the data line farthest from the shooting screen corresponding to the data in the imprint data to the end of the adjacent shooting screen is always a predetermined value or more regardless of the amount of the imprint data. By adjusting the interval, the film cutting position does not overlap the perforation hole even when the film is cut between the imprinted data portion corresponding to a certain screen and the edge portion of the adjacent photographing screen.

Further, when all the data cannot be projected in the interval between the photographing screens set by the setting means, the warning means can be used to give a warning.
It is possible to prevent data setting mistakes.

In addition, as shown in FIG. 1, such an imprinting head 15H is arranged in the vicinity of the take-up spool 13 side of the photographic screen so that the space between the imprinted character and the end of the photographic screen is 0.5 mm, for example. It is located in.

FIG. 4 shows a configuration example of the control panel 40 of the data imprinting section 15. This data imprinting section 15
For example, the projection head 15 is provided on the back of the camera back cover.
Data is imprinted by controlling H. Figure 4
The control panel 40 shown in FIG. 1 includes a display unit 41 having, for example, one set mode display line and one imprinted data content display line. Further on the display panel 40,
Up button 42, down button 43, left button 44, right button 45, set button 46,
An enter button 47, a clear button 48, a pitch button 49, and a print button 50 are provided.
The buttons 42 to 45 are the set button 46, the enter button 47, the clear button 48, and the pitch button 4.
9. Used in combination with each function button of the print button 50, the number of data lines to be imprinted, the imprinting mode, characters and numbers are set.

The display section 41 has a setting mode display line "upper stages 41a to 41d" and a imprinted data content display line "lower stage 41e" showing one line of setting conditions. Upper stage 41a
"3" displayed in "" indicates the display line number currently displayed in the lower row. Further, "(5)" displayed at 41b indicates the total number of lines to be imprinted. Also, 4
"* MAN" displayed in 1c indicates the imprinting mode of the line currently displayed, and "* MAN" indicates the imprinting mode of arbitrary characters and numbers. Furthermore, 4
"-4" displayed in 1d indicates a frame feed pitch setting value, and "-4" indicates a pitch setting of 288 mm in which four frames are imaged at equal intervals. Further, "TAROU" in the lower stage 41e indicates the content of the imprinted data.

Next, the function of each button will be described in more detail. The imprinted data setting mode can be turned on or off by pressing the set button 46. Further, by pressing the print button 50 while pressing the set button 46, it is possible to set ON / OFF of the data imprinting operation.

When the imprinting data setting mode is off, the display line can be changed by the up button 42 and the down button 43. Imprinted data
When the setting mode is on, the numeral portion of the display line is first displayed in reverse, that is, the black and white display is reversed and the display line is changed. This state is now temporarily referred to as state A.

In this state, by pressing the up button 42 or the down button 43, the display line can be changed. When the up button 42 is pressed, the line is changed to the previous line, and when the down button 43 is pressed, the line is changed to the next line. Move. Further, when the enter button 47 is pressed in the state of changing the display line, one line interrupt is added before the line displayed so far. In this case, the numerical value indicating the total number of lines displayed on the right is increased by one. When the clear button 48 is pressed in the display line changing state, the currently displayed one line is deleted, and the displayed numerical value of the total number of lines on the right is subtracted by one.

The display line display section 41a and the total line number display section 41b can each display a 2-digit numerical value.
As will be described later, since it is necessary to count the number of display lines up to 127 lines, 100 after "99" is displayed as "A
0 ", 101 is" A1 ", ..., 109 is" A9 ", 11
0 is represented as "B0", ..., 120 is represented as "C0", ..., 127 is represented as "C7". This allows counting up to 127 on the 2-digit display. When the light button 45 is pressed in the display line changing state, the display line imprinting mode is changed. The numbers on the display line are in the normal display state, and the mode display portion is now in reverse display. This is assumed to be state B.

In the imprint mode changing state, the imprint mode of the display line is selected by the up button 42 or the down button 43.

The imprinting mode can be set for each imprinting line. An automatic imprinting mode (year / month / day (* YMD) to hour / minute / second (* HMS), photographing shutter speed and photographing lens aperture value ( * T + F), Addition / subtraction value imprint mode (* U
PC, * DNC), imprint mode (* MAN) of arbitrary characters (including numbers), blank line mode (***), etc. are prepared.

When the enter button 47 is pressed after the selection of the imprinting mode is completed in this way, the imprinting mode of the display line is confirmed and the display of the next line is started. That is, the state A is returned to.

In the selection of the imprinting mode, when the addition / subtraction value imprinting mode (* UPC, * DNC) and the arbitrary character / numerical imprinting mode (* MAN) are selected, the imprinting data is operated by the operation of the light button 45. Move to the content setting state. In this case, the mode display portion returns to the normal display, and the leftmost digit of the imprinted data content display in the lower row becomes the reverse display. This state is assumed to be state C.

In this state, the light button 45,
The left button 44 is used, and the up button 42 and the down button 43 are used to set imprinted characters for each digit. This setting is performed by selecting AZ, 0-9, and blank with the up button 42 and the down button 43. After setting the characters to be imprinted for each digit in this way, the characters or numbers to be imprinted are confirmed by the enter button 47. If the clear button 48 is pressed while setting the data contents, the digits displayed in reverse are erased and the character / numeric string is sequentially left-justified.

In the display example of FIG. 4, the letter "U" at the fifth digit of the character string to be imprinted in the arbitrary character / numerical imprinting mode is reversely displayed in three of the five imprinted data lines. And shows the selected state.

When the pitch button 49 is pressed, the frame feed pitch setting mode is entered regardless of whether the imprinting data setting mode is on or off. In this state, the frame feed pitch setting value is displayed in reverse. This state is assumed to be state D.

In this state, the up button 42,
Use the down button 43 to set the frame feed pitch to "-
After selecting one of “6” to “−1”, “−−”, and “−P”, the frame feed pitch setting is confirmed with the enter button 47. In this case, "-6" to "-1" indicate the pitch setting for imprinting 6 to 1 frames at a uniform interval with a film length of 228 mm. The film length is set to 228 mm as a unit because, as described above, the length can be arranged in a general film storage case that stores 6 frames of film in each stage. In this case, the frame feed amount and the frame distance are the values shown in Table 1. Table 1 Frame feed Feed amount Distance between frames Imprinting Pitch setting Number of lines that can be set (mm / frame) (Hole / frame) (mm) (lines) -6 38 8 2 1 -5 45.6 9.6 9.6 6 -4 57 12 21 13 -3 76 16 16 40 26 -2 114 24 78 51 -1 228 48 192 127

By setting the pitch as described above, as will be described in detail later, the film edge of the film is placed at a predetermined distance from the center of the perforation holes of the film, that is, the cutting margin, so that the film can be easily cut. Winding is controlled. In this case, the cutting portion does not overlap the perforation hole position, which is convenient for cutting.

However, with the setting of "-5", the position of the edge of the photographing screen cannot always be set due to the relationship between the frame feed amount and the interval of the perforation holes. In the case of "-5",
The winding is controlled so that the first frame of shooting has a positional relationship with the end of the shooting screen. Hereinafter, the sixth frame, the eleventh frame, the sixteenth frame, ... Are in the positional relationship of the photographing screen edge. By setting in this way, the perforation hole is not caught in the cut portion in the unit of the film length of 228 mm, and the condition of easy cutting is satisfied.

In the setting of "---", the interval from the last line in the imprint data to the edge of the next photographing screen is always the disconnection margin of 2.
The winding is controlled so as to double the length. This is to ensure a predetermined cutting margin even for the last line and the cutting portion in the imprinted data. In this case, the positional relationship of the perforation holes is not considered.

In the setting of "-P", the distance from the last line in the imprint data to the edge of the next photographing screen is more than twice the cutting margin, and the photographing screen edge is the distance from the center of the perforation hole to the cutting margin. The film winding is controlled so that The setting of "-P" always satisfies the condition of easy cutting.

The frame feed pitch setting is "-6" to "-".
When "1", the frame feed amount is fixed, and as shown in Table 1, the number of lines that can be imprinted is fixed. Therefore, when the number of lines to be imprinted exceeds the number of lines that can be imprinted when the number of lines to be imprinted is changed, that is, when the number of lines is added in state A, the numerical value of the total number of lines is displayed in the normal or reverse display. Repeat warnings. Alternatively, a warning buzzer (not shown) may be used to give a warning. Data lines exceeding the number of printable lines will not be accepted.

After confirming the frame feed pitch setting in this way, pressing the enter button 47 completes the setting.
It returns to the state before pressing the pitch button 49.

The above are the conditions mainly set prior to a series of shooting operations. Next, the settings made during shooting will be described.

When the frame feed pitch setting is "---", pressing the print button 50 while pressing the enter button 47 causes the additional imprinting mode. The additional imprint data is set line by line. In the additional imprinting mode, the display line display portion becomes "AD", and the display values of all lines are incremented by one. In this case, the mode display portion is a reverse display. This state is assumed to be state E.

The setting method in such a state may be the same as the setting method in the imprint mode changing state.

After the setting of the additional imprint data is completed in this way, when the print button 50 is pressed again alone, the additional imprint data is imprinted between the frames of the film. Additional imprints can be repeated as many times as the film can be wound.

FIG. 5 shows a schematic configuration of an electric circuit of a camera with a data imprinting device according to the present invention. As shown in the figure, each peripheral device and the like are connected to the camera control unit 10 including a microprocessor and the like. That is, the camera control unit 10 has the configuration shown in FIG.
A film winding motor 14, an encoder 18 for detecting the film feed amount, a film D
A film information detecting section 19 such as a DX contact section for detecting an X code is connected. A data imprinting section 15 arranged on the back cover of the camera is further connected to the camera control section 10. The data imprinting section 15 includes a data imprinting head 15H and a control panel 40. The camera control unit 10 is also connected to a hole position detection unit 21 that detects the relative position between the perforation hole of the film and the screen.

Next, the data imprinting procedure of the camera according to the present invention will be described focusing on the operation of the camera control section 10. FIG. 6 shows a data imprinting procedure in a camera with a data imprinting apparatus according to an embodiment of the present invention. In the figure, after the completion of the film loading, when the back lid closing detection means (not shown) detects the back lid closing,
The process is started from step (hereinafter abbreviated as S) 5, and S10 is performed.
Then, the winding motor 14 is driven to start film winding.

During the film winding operation, the winding amount is monitored by a pulse signal from the encoder 18 in the next S15 to detect whether or not the preset initial winding amount has been reached. If it is insufficient, continue winding while detecting the feed amount. When it is detected that the preset initial winding amount is reached, the process proceeds to S20.

In step S20, it is detected based on the signal from the hole position detector 21 whether or not the perforation hole 12P is located at a position where the perforation hole 12P is away from the photographing screen 20 by the distance for cutting and is easy to cut. The position at which cutting is easy means, for example, when the central portion between the perforation holes 12P is at a position of, for example, 1 mm (= cutting margin) with respect to the end portion of the photographing screen 20. Further winding is continued until the perforation hole 12P reaches the position that satisfies this condition.

Perforation hole 1 at a position where cutting is easy
When 2P arrives, the process proceeds to S25 to stop the winding. Next, in S30, the amount of film that has been wound up is calculated. This value can be obtained by integrating the pulses from the encoder 18 from the start of film winding.

Next, in S35, the amount of the remaining portion of the unexposed film, that is, the remaining film length is calculated. First, the signal from the DX contact portion 19 is used to detect how many frames the currently used film is. Next, multiply the feed amount (usually 38 mm) for each frame that defines the number of frames that can be photographed on the film by the above number of frames,
By adding a predetermined blank feed expected amount, for example, 200 mm, the drawable amount of the film in use, that is, the total length of the film can be calculated. For example, for a film of 36 shots, (38 × 36) + 200 = 1518 mm.
Since the film winding length has already been calculated in S30, the required film remaining length may be calculated by subtracting the film winding length from the film drawable amount, that is, the total film length.

Next, in S40, the total number of frames that can be photographed on the entire film is calculated. This value is a calculated value for the frame feed amount based on the currently set frame feed pitch setting and the frame feed amount determined by the number of imprinted data. It is a numerical value obtained by adding 1 to the integer part of the numerical value ordered by the quantity (this numerical value is the number of remaining frames) (since the first frame has already been wound up).

Next, in S45, the total number of frames calculated in S40 is displayed on 31C of the display section 31. By the way, the number of remaining frames displayed on 31A of the display unit 31 is a numerical value of the total number of frames-1, and the number of shooting frames displayed on 31B is "1". After the processing of S45 is completed in this way, S5
The routine ends with 0.

In the example described above, including the display example of FIG. 2, the number of photographed frames, the number of remaining frames and the total number of frames are displayed, but the photographer is informed of various frame numbers. Since the purpose is to give, as will be described later, it is not necessary to display all the above three numerical values.

FIG. 7 shows the procedure of the data imprinting process and the film winding process in the camera with the data imprinting device according to one embodiment of the present invention, in which the frame feed pitch setting is "-6" to "-1". Is the case of. Similar to the case of FIG. 6, the processing of FIG. 7 is also performed by the camera control unit 10.

In FIG. 7, the routine is started from S100 at the same time when the photographing operation of the camera is completed.
Drive the winding motor 14 to wind the film with a predetermined screen feed amount. Here, the predetermined screen feed amount is a shooting screen width of 36 mm + shooting screen to data first line margin 0.5 mm + data character height 1 mm + data line margin 0.5 mm = 38 mm.

During the film winding operation, the winding amount is monitored by the pulse from the encoder 18, and the winding is stopped when the predetermined screen feed amount is reached. By such a winding operation, the photographing screen corresponding to the imprint data is taken up by the take-up spool 1 rather than the imprint head 15H.
Move to side 3. The data imprinting side end (rear end) of the photographing screen corresponding to the imprinting data is positioned 0.5 mm from the character imprinting portion of the imprinting head 15H on the take-up spool 13 side.

Next, in S115, the imprinted data content set in the data imprinting section 15 is set to the content of the first line. Then, in step S120, the data for one line is imprinted.

Next, in step S130, it is determined from the information from the data imprinting section 15 whether or not the imprinting of the data row to be imprinted is completed. If the data imprinting is not completed, that is, if the data imprinting unit 15 is set to imprint a plurality of lines of data, the process proceeds to S140. S1
In 40, the take-up motor 14 is driven to wind the film for the line feed of the imprinted data, that is, the data character height + line spacing margin (1 mm + 0.5 mm = 1.5 mm). Also in this winding operation, the winding amount is monitored by the pulse from the encoder 18, and the winding is stopped when a predetermined imprint data line feed amount is reached. After the stop, in S150, the imprinted data content set in the data imprinting section 15 is line-wrapped to be changed to the content of the next line, and the process returns to S120 to imprint the data of the next line. Such processing is continued until the imprinting of all the imprinted data rows set in the data imprinting section 15 is completed.

In this way, when the imprinting of all the imprinted data rows is completed, the determination in S130 results in S16.
Go to 0. In S160, the stored value of the number of photographed frames is set to 1
Count up. Further, the winding amount insufficient in frame feeding is calculated by subtracting the winding amount in S110 and S140 from the frame feeding amount set in the next S170. Then, in S180, the winding motor 14 is driven, and while the winding amount is monitored by the pulse from the encoder 18, the above shortage amount is set to a predetermined frame feed amount.

The frame feed pitch setting is "-6", "-"
4 "to" -1 ", perforation hole 12P
Is always at the easy-cutting position as described in the description of the above-mentioned idle feed routine, so that the perforation hole 12P becomes the easy-cutting position in consideration of the signal from the hole position detection unit 21 in addition to the pulse signal from the encoder 18. Winding control is performed. However, when the frame feed pitch is set to "-6", there is no insufficient winding amount and the winding operation of S180 is not actually performed. Further, in the case of "-5", winding control may be performed so that the perforation hole 12P is at the easy-cutting position in the same manner as above when the first frame, the sixth frame, the eleventh frame, ....

Next, in S190, the amount of film that has been wound up is calculated. This value can be obtained by integrating the pulse from the encoder 18 from the winding when the film is loaded. Next, in S200, the amount of the unexposed film remaining portion, that is, the film remaining length is calculated. This can also be obtained by subtracting the rolled-up length obtained in S190 from the total film length obtained in S35.

Next, the number of frames that can be photographed with the remaining film is calculated in S210 using the value of the remaining film length thus obtained. This value is a calculated value using the frame feed amount under the currently set conditions, and is an integer value of a numerical value obtained by dividing the remaining film length by the frame feed amount. Next, S2
At 20, the total number of frames of the entire film is calculated. This number is S
It is a numerical value obtained by adding the remaining number of frames calculated in S210 to the number of imaged frames calculated in 160. Then proceed to S230,
The number of shooting frames, the number of remaining frames, and the total number of frames calculated in S160, S210, and S220 are 31B, 31A of the display unit 31,
31C is displayed respectively. In addition, the above S190-
The step of S230 is collectively referred to as SS190-230 and will be used in the description below.

After the above processing is completed, the routine is ended in S240. In the example of this figure, by displaying the number of frames to be photographed, the number of remaining frames, and the total number of frames, the photographer is provided with the latest information on various numbers of frames one by one, thereby preventing an unexpected film break. However, it is also possible to display the number of shooting frames and the total number of frames, or display only the number of remaining frames, depending on conditions such as the size of the display portion. Alternatively, as shown in 31D of FIG. 2, when the number of remaining frames becomes less than or equal to a predetermined value such as 2 frames, a display warning is given by a frame number warning mark display or a blinking display, or illustrated. An alarm buzzer may be used to generate an alarm sound.

By the above-described operation, it is possible to obtain a photographic film in which a plurality of lines of data are imprinted between film frames and which can be cut in a form that is easy to organize. In addition,
In the above embodiment, in calculating the film length, the number of frames of the film in use was detected by the DX contact portion 19, but in order to obtain the film information D
It is also possible to use means other than the X contact portion. Also,
The film information is a film frame number selection switch (for example, 12
The number of frames and the film length of the film to be used may be set by the EX, 24EX, 36EX selection method, or a means capable of setting the number of frames and the film length numerically. In the latter case, special films and long magazines can be used.

FIG. 8 shows an example of a film in which data is imprinted between the frames by the above operation, and in this case, the frame feed pitch setting is "-4". With this setting, the frame feed pitch is 12 holes / frame, and the perforation hole 12P and the edge of the photographing screen are in the easy-cutting position relationship.

Data of three lines of an arbitrary character, a date, and an arbitrary character are imprinted in the p portion between the frames. In addition, arbitrary character, year / month / day, arbitrary character, hour / minute / second, shutter speed and lens aperture value, and then 2 lines of arbitrary character and a total of 8 lines of subtraction value for each shooting frame are imprinted on the q section between frames. It is rare.

FIG. 9 shows a data imprinting procedure when the frame feed pitch setting is "---". It should be noted that in FIG. 9, the same steps as those in FIG.

In the process of FIG. 9, first, as in the case of FIG. 7, the steps from S100 to S110 to S160 are common. Further, S170 in FIG.
And the step of S180 is not included. S160
After that, in S175, additional winding is performed so that the interval from the last line in the imprinted data to the end of the next shooting screen is twice the cutting allowance. In the additional winding, at the end of S110 or S140, the distance between the last line in the imprint data and the next photographic screen is 0.5 mm, because of the positional relationship between the imprint head 15H and the photographic screen 20. ,
It is performed by further winding up 1.5 mm so that this interval is 2 mm, which is twice the cutting margin. Also in this case, the winding motor 14 is driven and the winding amount is monitored by the pulse from the encoder 18 to perform additional winding to secure the cutting allowance, and when the predetermined amount is reached, the winding motor 14 is stopped.

The next steps SS190-230 are similar to those of FIG. However, when calculating the number of frames that can be photographed with the remaining film in S210 of SS190-230, the frame feed amount that is the basis is the screen feed amount (38 m
m) + [{number of imprinted data lines-1} x data line feed amount (1.5 mm)] + cutting allowance feed amount (1.5 mm)
To use.

In the frame feed pitch setting described in this figure, the photographing screen position and the perforation hole position are indefinite, so that it is not always convenient for film cutting.
However, since the frame interval is determined by the number of lines of the imprinted data, there is an advantage in effective use of the film. Moreover, since a certain cutting allowance is secured, it is possible to cut between the imprint data and the next shooting screen with a margin.

FIG. 10 shows an example of a film in which data is imprinted between the frames by the processing procedure of FIG. 9 when the frame feed pitch setting is "---". A portion corresponding to the q portion is shown. In this case, the frame feed pitch is indefinite, and the next photographing screen edge comes from the last line of the imprinted data to a position twice the cutting margin.

FIG. 11 shows a data imprinting procedure when the frame feed pitch setting is "-P". Also in FIG.
The same steps as those in FIGS. 7 and 9 are designated by the same reference numerals and the description thereof will be omitted.

Also in the processing procedure of FIG. 11, first of all, as in the case of FIG. 7, starting from S100, the steps up to S160 are common. Moreover, the steps of S170 and S180 are not included. After S160, S is performed as in FIG.
At 175, additional winding is performed to secure the cutting allowance.

Next, in step S185, it is determined whether or not the perforation hole 12P is at the easy-cutting position with respect to the photographing screen 20 based on the signal from the hole position detecting section 21. If it is in the easy cutting position, SS190
Proceed to -230. If the perforation hole 12P is located at the easy-cutting position based on the signal from the hole-position detecting unit 21, it is wound up by the routine of S187 and S185 if it is not at the easy-cutting position. When the cutting easy position is reached, the winding motor 14 is stopped, and SS
Proceed to 190-230. However, in this example, SS190-2
Of the 30 steps, the basic frame feed amount when calculating the number of frames that can be photographed with the remaining film in S210 is the screen feed amount (38 mm) + [{imprinted data line number-1} ×
Data line feed amount (1.5 mm)] + cutting allowance feed amount (1.5 mm) + perforation hole pitch amount (4.
75 mm) is used. The perforation hole pitch amount is added in consideration of the winding amount in each subroutine of S187 and S185.

In the case of setting the frame feed pitch in the case of FIG. 11, the relationship between the photographing screen position and the perforation hole position is always the easy cutting position, which is convenient for cutting.
Moreover, since the spaces between the frames are reduced according to the number of lines of the imprinted data, it is advantageous in that the film can be effectively used next to the frame feed pitch setting of "---".

FIG. 12 shows an example of a film on which data is imprinted between the frames when the frame feed pitch setting is "-P" as described above. In this case, a portion corresponding to the q-interval between the frames shown in FIG. 8 is shown as a q2 ′ portion. In this case, the frame feed pitch is indefinite, but the margin between the last line of the imprinted data is more than twice the cutting allowance, and the perforation hole 12P and the photographing screen edge are in the easy cutting position. The parts are spaced apart.

FIG. 13 shows a processing procedure in the case where the frame feed pitch setting is "---" as shown in FIG. 9 and additional data is imprinted. In FIG. 13, S
SSs 190-230 up to 175 are common to FIG. After S230, the process proceeds to S232 described in this figure.

In S232 and subsequent S236, the imprinting signal of the additional imprinting data line issued by the operation of the print button 50 of the data imprinting section 15 (at this time, the contents of the additional imprinting data line have already been determined), Alternatively, it waits for the input of a release signal for avoiding the next shooting operation issued from the release pants not shown.

That is, when the imprinting signal input of the additional imprinting data line is detected in S232, the process proceeds to the additional data imprinting subroutine of S234. In S234, similarly to S120, the data imprinting unit 15 is imprinted with the data of the additional row. At this time, the last line of the data already imprinted is closer to the take-up spool 13 side than the imprint head 15H by the additional winding in S175. Therefore, even if the additional printing is performed in S234, it is possible to print the additional row with a data line margin of 0.5 mm secured. S234
When the processing of step S1 is finished, the control returns to step S175, and the processing of step S1
At 75, additional winding is performed to secure the cutting allowance. After that, the process proceeds to SS190-230, and the amount of film already wound is calculated again. This is because the amount of film that has been wound changes because the additional winding is performed in S175. Note that the data imprinting feed amount corresponding to the preset number of data lines is used as the basic data imprinting feed amount at the time of the above recalculation without adding the number of data lines for the additional imprinting. This is because the additional imprint can be considered as an emergency measure.

When the imprint signal input of the additional imprint data line is not detected in S232, the process proceeds to S236.
In S236, if the release signal is not detected, S
Returning to step 232, however, if a release signal is detected, the next shooting operation starts, so the process advances to step S240 to end the processing of this data imprinting routine.

By such processing, even after the normal data imprinting routine is completed, it is possible to imprint as much additional data as desired before the start of the next photographing operation. Moreover, since the data is copied between the frames, it does not affect the shooting screen at all. Further, it is possible to immediately respond to a change in the remaining amount of the film due to additional imprinting and notify the photographer of accurate remaining film amount information.

In the description of each of the above-mentioned embodiments, the general winding method has been described in which the film is wound from the cartridge and the photographing is sequentially performed, but the present invention has been performed recently. The film is wound on the spool from the cartridge, and the system is used for shooting while rewinding the film onto the cartridge).

That is, the film cartridge 1 shown in FIG.
1. By reversing the arrangement of the DX contact portion 19 and the take-up spool 13, the camera of the present invention can be easily constructed. At this time, the rewinding operation is sequentially performed from S20 described in FIG.

When this pre-rewind method is used, there is also an advantage that the total length of the film can be confirmed by the encoder 18 when the spool is first wound up.

[0093]

As described above, according to the present invention, a plurality of lines of data can be imprinted between film shooting screens, that is, between frames, and the frame interval can be adjusted to a desired value. be able to. For this reason, for example, with a fixed interval between frames for easy film organization, a large number of data with high proof ability desired by a photography company is not affected on the photography screen, and therefore the quality as a recorded photograph is not deteriorated. It becomes possible to imprint between the pieces inside.

In addition, since a warning can be issued when the amount of imprinted data set is too large to fit between the frames at the above-mentioned fixed intervals, an error in setting the amount of data can be prevented. Furthermore, if necessary, even after the end of the series of data imprinting routines and before the start of the next photographing operation, any number of additional data can be imprinted. Further, by providing a display of the number of remaining frames of the film and a warning of the remaining amount, it is possible to prevent the inconvenience that the remaining number of the films is predicted and the remaining amount of the film is insufficient without noticing.
