Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a micro camera for photographing a document on film. That is, the present invention relates to a micro camera that reduces a document set at a photographing position, projects the image onto a film, and photographs a large number of images.

"Prior Art" Photography using such a micro camera has conventionally been generally performed in the following steps.

In other words, the operator first sets the original at the photographing position on the document table, then turns on the bottom switch and instructs the operator to take a photograph.After the prescribed photographing process is performed, the original is removed and the next new original is placed. It was set.

On the other hand, in the examples of JP-A-57-164730,
The following techniques are shown.

In other words, a memory device that sequentially stores the operation of various operation switches of such a micro camera and a readout switch for the contents of this memory device are provided, and when the operator feels the need for confirmation after the fact, he can operate the readout switch. According to
The contents of the storage device were used to operate the display corresponding to the operation switch.

"Problems to be Solved by the Invention" By the way, the following problems have been pointed out with such conventional micro cameras.

First, in the conventional general case, after setting the original and before turning on the shooting switch, if the operator leaves the area and turns his attention to another matter, the original that was set and left behind will be removed. , I often forgot whether or not I had turned on the photographing switch, that is, whether or not I had taken a photograph.

With an electronic copying machine or the like, the presence or absence of a copy can be immediately confirmed by looking at the copy, but with a micro camera, the presence or absence of an image cannot be confirmed until the film is developed. In the conventional example, such inconvenience is a problem, and it has also been pointed out that photographing errors such as overlapping overshadowing of the document and not photographing due to misremembering have also been pointed out.

On the other hand, the technique disclosed in Japanese Patent Application Laid-Open No. 57-164730 requires the operator to operate a readout switch each time he or she is confused about the necessity of such confirmation.
Problems include inconvenience, such as being troublesome and lacking in timeliness. Furthermore, even if a document is left behind and photographed, a subsequent check using the readout switch will display that the photographing switch is on, which may lead to photographing errors such as mistaking the document for photographing.

In the conventional example, such a point was pointed out.

In view of these circumstances, the present invention has been made in order to solve the problems of the conventional example described above, and the present invention allows the display means to indicate that no photograph has been taken based on the signals from the predetermined detection means and instruction means. The purpose of the present invention is to propose a micro camera that displays information and notifies the operator, so that it is possible to easily and immediately confirm whether or not a document has been photographed, and in particular, eliminates the possibility of forgetting to photograph and realizes more reliable photographing.

"Means for Solving the Problem" The technical means of the present invention to achieve this object are as follows.

This micro camera takes a full-frame photograph of a document set at a photographing position. It also has the following detection means, instruction means, and display means.

The detection means detects the presence or absence of the document at the photographing position.

The instruction means instructs to photograph the original on the film.

The display means in claim 1 displays information indicating that no photographing has been performed when a predetermined time elapses without a photographing instruction being issued by the instructing means while the presence of a document is detected by the detecting means.

Further, the display means in claim 2 provides information indicating that the document has not been photographed, when the detection means detects that the document is not present without giving a photographing instruction by the instruction means after the presence of the document is detected by the detection means. Display.

"Function" Since the micro camera according to the present invention is comprised of such means, it has the following functions.

First, when a document is set at the photographing position, the presence of the document is detected by the detection means.

According to claim 1, if a predetermined period of time elapses without the instruction means performing a photographing instruction, that is, photographing processing, while the presence of a document is detected in this way, the display means displays a message indicating that no photograph has been taken yet. Display information to let the operator know that the document has not yet been photographed.

Further, in claim 2, after the presence of a document is detected in this way, if the detection means detects that there is no document without the instruction means issuing a photographing instruction, that is, the document is removed without being photographed. From then on, the display means displays information indicating that the document has not yet been photographed, informing the operator that the document has not yet been photographed.

Therefore, confirmation of whether or not the document has been photographed can be easily and immediately carried out as needed, and in particular, forgetting to take a photograph can be eliminated and more reliable photographing can be achieved.

"Example" The present invention will be described in detail below based on the example shown in the drawings.

First, its configuration will be described in the following order: an overview of the microcamera, detection means, instruction means, and display means.

FIG. 1 is an external perspective view showing an embodiment of a micro camera according to the present invention. FIG. 2 is a plan view of the document table.

The outline of the micro camera is as follows.

The illustrated micro camera is of a manual type, and a support 2 is erected at the rear end of a base 1. The support column 2 is vertically expandable and retractable, and a pair of arms 3 are attached to the left and right sides, and each arm 3 is provided with a lighting unit 4 such as a lamp to face each other.

A camera head 5 is fixed to the upper end of the column 2.

Inside the sealed box-shaped camera head 5, there are provided a raw film supply reel, an exposure section, a film feeding mechanism, a film take-up reel, etc. (not shown).

Further, a document table 6, which is a copy board, is fixed on the base 1. This document table 6 is located below between the above-mentioned illumination units 4, and has a key frame 7 attached to its surface. This key frame 7 indicates the range that can be photographed by the above-mentioned camera head 5, and a document (not shown) is set at a photographing position within this key frame 7.

Since the micro camera is configured as described above, the light from the illumination unit 4 reaches the camera head 5 after irradiating the document set at the photographing position. Then, the lower surface of the film is projected and exposed through an exposure unit such as a lens, shutter, or aperture. As a result, a large number of original documents are photographed and processed as reduced images on film.

A micro camera generally looks like this.

Next, the detection means will be described.

The detection means detects the presence or absence of a document at the photographing position.

In the illustrated example, a reflective photosensor is used as the detection means.

That is, the detection element 8 is arranged near the center of the key frame 7 of the document table 6. FIG. 3 is a front explanatory view showing such a detection needle 8, and (1) shows a state with no document.
2) The figures each show a state with a document present.

First, as shown in FIG. 3 (1), when the original S is not set at the photographing position on the original platen 6, the light from the light emitting part 8I of the detection element 8 escapes upward. Light receiving section 8. No light enters. Therefore, the detection element 8 is turned off and it is determined that the document S is absent.

As shown in FIG. 3(2), when the document S is set at the photographing position on the document table 6, the light emitting portion 8 of the detection element 8. The light from the document S is reflected by the back surface of the document S and enters the light receiving section 8□. Therefore, the detection element 8 is turned on and it is determined that the document S is present.

In the illustrated example, the detection element 8 made of a reflective photosensor is used as the detection means, but it is also possible to use, for example, an ultrasonic sensor, a limit switch, or other various sensors.

Also, as a micro camera, it is not a manual type as shown in the diagram.
If a method is adopted in which the document S is automatically transported to the photographing position on the document table 6 using a document feeder, etc., the document S is transported to the photographing position and the document S is photographed during the transport path of the document S. It is also possible to consider a detection means that detects the removal from the position and detects the presence or absence of the document S at the photographing position based on the detection result.

The detection means is like this.

Next, the instruction means will be described.

FIG. 4 is a block diagram showing the control means of this micro camera.

The instruction means instructs the photographing of the document S onto a film. That is, a button-type photographing switch 9 serving as an instruction means is provided at the front end of the base 1.

When the photographing switch 9 is pressed, an instruction signal is input to the microcomputer 10, and the microcomputer 10 outputs corresponding drive signals to the feed mechanism, aperture, shutter, etc. of the camera head 5, and performs photographing processing. will be held.

The instruction means is as follows.

Next, the display means will be described.

First, the display means in claim 1 is such that, while the presence of the document S is detected by the detection element 8 which is the detection means, if a predetermined period of time elapses without a photographing instruction being issued by the photographing switch 9 which is the instruction means, it is determined that no photograph has been taken. Display information to that effect.

Further, the display means in claim 2 is such that after the presence of the document S is detected by the detection element 8 which is the detection means, the detection element 8 is displayed without a photographing instruction being given by the photographing switch 9 which is the instruction means.
When the absence of the document S is detected, information indicating that the document has not been photographed is displayed.

In the illustrated example, such a display means includes a display section 11 that is provided at the front end of the base 1 and turns on a lamp when the display is on and turns off the lamp when the display is off, and a display section 11 that emits a warning sound to instruct and prompt photography when the display is on. A warning section 12 that stops this by turning off the display,
It is used. That is, in the illustrated example, the display section 11 and the warning section 12 are used as display means, but only one of them may be used. Furthermore, the display means are not limited to these, and various other display methods can be considered, such as methods that use color changes, numbers, etc., methods that appeal to the senses using other lights, methods that appeal to the senses of hearing using other sounds, etc. It will be done.

In claim 1, it is as follows. That is, a detection signal indicating that the document S exists is sent from the detection element 8 to the microcomputer 1.
0, if a preset predetermined time period elapses without an instruction signal being input from the photographing switch 9, the microcomputer 10 outputs a display signal to the display means and turns on the display. In the illustrated example, the display section 11 lights up and the warning section 12 starts emitting a warning sound.

Then, the display section 11 that has been turned on in this manner and the warning section 12 that emits the warning sound are turned off and the warning sound is stopped after the fact, for example, when an instruction signal is input from the photographing switch 9.

In addition, claim 2 is as follows. That is, the detection element 8
After the detection signal indicating that the document S is present is input to the microcomputer 10, if the detection signal indicating that the document S is not present is input from the detection element 8 without receiving the instruction signal from the photographing switch 9, the microcomputer 10 A display signal is output to the display means and the display is turned on. In the illustrated example, the display section 11 lights up and the warning section 12 starts emitting a warning sound. Then, the display section 11 that has been turned on in this manner and the warning section 12 that emits the warning sound are turned off and the warning sound is stopped after the fact, for example, when a detection signal indicating that the document S exists is inputted from the detection element 8.

The display means is like this.

The micro camera according to the present invention is as described above.

The operation etc. will be explained below.

First, claim 1 will be described. FIG. 5 is a flowchart showing an example of the control, and the operation etc. will be explained with reference to FIG.

First, when a power switch (not shown) is turned on, initial settings are performed in step (2) in FIG. Then step
Then, the detection element 8 monitors and determines whether or not the original S has been set at the photographing position on the original platen 6. When the operator places the document S, the detection element 8 turns on and detects the presence of the document S, and the process proceeds to the next step (2).

In step (2), it is determined whether or not a photographing instruction has been issued using the photographing switch 9. Here, when the operator turns on the photographing switch 9, the process proceeds to step (3), where a predetermined photographing process is performed, and the document S is photographed as an image on a film. Thereafter, the photographed original S is removed from the original table 6, and the flow returns to step (2), whereupon a new original S is set.

Now, if no photographing instruction is given by the photographing switch 9 in step (2), the process proceeds to step (2) and it is determined whether a predetermined period of time has elapsed since the detection element 8 was turned on. If the predetermined time has not yet passed here, the flow returns to step (2).

If it is determined in step (2) that a predetermined period of time has elapsed without a photographing instruction being given, the process proceeds to step (2) where the display is turned on, the display section 11 lights up, and the warning section 12 begins to emit a warning sound.
Information indicating that the document S has not yet been photographed is displayed to notify the operator.

After that, the flow goes to step (2), in which it is again determined whether or not a photographing instruction has been issued using the photographing switch 9 for the document S. Then, when the operator notices that no photograph has been taken and turns on the photographing switch 9, the process proceeds to step ■ and the display turns off.
The display section 11 turns off and the warning section 12 stops emitting the warning sound. Then, the flow advances to step ■↑ where the sub-sinking process is performed.

Now, in step ■, if the operator does not turn on the photographing switch 9 and it is determined that the predetermined time has elapsed after proceeding to step ■, the display is turned off in step 0, the display section 11 goes out, and the warning section 12 emits a warning sound. stop. Note that if the predetermined time has not yet elapsed in step (2), the flow returns to step 0.

Now, if the display turns off in step [phase], for example, the original S
After the document S is removed from the document table 6, the flow returns to step 0, and a new document S is eventually set.

Note that the content of the determination in step (2) may be, instead of determining whether the predetermined time has elapsed as described above, for example, determining whether the detection element 8 is OFF in order to check whether the document S has been replaced as described above.

Now, regarding the unpossessed manuscript S, the above-mentioned display is performed.

Therefore, confirmation of whether or not the document S has been photographed can be easily and immediately performed as necessary based on the information that the document S has not been photographed, and in particular, forgetting to photograph can be eliminated and more reliable photographing can be achieved. become.

For example, after setting the document S and before turning on the photographing switch 9, the operator leaves the area and turns his attention to another matter, and if a predetermined period of time has elapsed, he may forget the document S. It may be stored away. Moreover, there are many cases where the user doubts whether or not the photographing switch 9 has been turned on, and forgets whether or not the photographing has been performed. Even in such a case, by displaying information indicating that the photograph has not yet been taken, confirmation can be easily and immediately performed, and the photographing process or the like that has been forgotten can be performed as appropriate.

Note that during a short period when the predetermined period of time has not elapsed, it is assumed that the operator is aware of whether or not the document S has been photographed, so there is no need to display the information.

The above is the explanation of the operation of claim I based on FIG. 5 etc.'
be.

Next, claim 2 will be described. FIG. 6 is a flowchart showing an example of the control, and the operation etc. will be explained with reference to FIG. 6 as well.

In the flow shown in FIG. 6, each step from the initial setting in step (2), through the determination of the detection element 8 and the photographing switch 9 in steps @ and 0, to the photographing process in step (2), is as described above. The steps from step 2 to step 2 through steps 2 and 3 described in FIG. 5 are exactly the same as those described in connection with FIG.

If the photographing instruction by the photographing switch 9 is not given at step (2) in FIG. 6, the process proceeds to step (2) and it is determined whether or not the document S has been removed from the photographing position of the document table 6 without being photographed. If it has not been removed, return to step 0 again. When the document S is removed and the detection element 8 is turned off and the absence of the document S is detected, the process proceeds to the next step [phase].

Then, in step ■, the display is turned on. In other words, display section 1
1 lights up, the warning section 12 starts emitting a warning sound, and displays information that the removed document S has not been photographed to inform the operator.

After that, the flow advances to step (2), where it is determined whether the original S has been set at the photographing position on the original table 6. That is, when the operator notices that the document S has not yet been photographed and replaces the document S, and the detection element 8 is turned on again, the process proceeds to step (3), where the display is turned off, the display section 11 is turned off, and the warning section 12 stops emitting the warning sound. Then, the flow returns to step (2), and when the photographing switch 9 is turned on, photographing processing is performed in step 0.

Now, if it is determined that the detection element 8 is not turned on in step O and that the predetermined time has elapsed after proceeding to step (2), the display is turned off in step [stock]. That is, if the operator does not reposition the document S within a predetermined time, it is assumed that the operator has no intention of photographing, and the display section 11 turns off and the warning section 12 stops emitting the warning sound. The flow then returns to step @.

Note that if it is determined in step (2) that the predetermined time has not yet elapsed, the flow returns to step (2).

Now, regarding the unphotographed document S, the above-mentioned display is performed.

Therefore, it is 1i1 whether or not the document S is photographed. Acknowledgment can be easily and immediately carried out as needed based on such information that the photograph has not been taken, and in particular, forgetting to take a photograph can be eliminated.
More reliable shooting will be realized.

For example, after setting the document S and before turning on the photographing switch 9, the operator may leave the area and turn his attention to another matter, and then the document Sometimes I forget whether or not I turned on 9. Even if the original S is removed without being photographed due to a misunderstanding as to whether or not it has been photographed, information indicating that it has not been photographed is displayed so that the original S can be replaced and photographed easily and immediately. Become.

The above is the explanation of the operation of claim 2 based on FIG. 6 and the like.

In the embodiments described above, the display means in claim 1 and the display means in claim 2 are provided and operated separately, but it is of course possible to use both together.

That is, first, the detection element 8 serving as the detection means detects the original S.
While the presence is detected, a predetermined period of time elapses without the photographing switch 9 being turned on, or secondly,
The display may be turned on either after the detection element 8 detects the presence of the document S, or when the detection element 8 detects the absence of the document S without the photographing switch 9 being turned on.

In this way, when either the first or second condition is met, it is also possible for the display means to display information indicating that no photograph has been taken.

"Effects of the Invention" As explained above, the micro camera according to the present invention has the following features:
Based on the signals from the predetermined detection means and instruction means, the display means displays information that the image has not been photographed and notifies the operator, making it possible to easily and immediately confirm whether the document has been photographed or not, and in particular eliminating the possibility of forgetting to photograph the document. This allows for more reliable shooting. In other words, it is extremely convenient to be able to check on the spot in a timely manner without having to develop the film and without requiring any operations.It also prevents duplicate shots due to misunderstandings or misunderstandings, and in particular prevents shooting mistakes such as not taking any pictures. The effects it brings are significant, such as eliminating the problems that existed in the conventional example.
