〔Example〕

The present invention will be explained below according to illustrated embodiments. 1st
FIG. 1 is an explanatory diagram showing a schematic configuration of an image reading device according to a first embodiment of the present invention. In the figure, 1 indicates an image reading device, and this device is provided with an autochanger 5 consisting of a tray 3 roughly installed on a tray stand 2 and a reading section 4 installed at the bottom of the tray stand 2. ing.

The tray stand 2 is rotatably installed by an autochanger drive circuit 6, and a plurality of storage sections 7 are formed radially at equal intervals around the center of rotation, and each storage section 7 is held by a slide mount 8. Each film F is stored as an image recording medium. As the tray 3 rotates, the films F stored in the storage section 7 are sequentially moved one by one to the supply position 9 above the reading section 4, and the films F that have been moved to the supply position 9 are taken into the reading section 4. information is read.

In the vicinity of the reading section 4, a sensor 1O is installed as a detection means for detecting the presence or absence of the film F in the storage section 7 located at the supply position 9, which detects the presence or absence of the film F in the reading section.

The film F sent to the reading position 11 in the reading section 4 is D
Light generated from a light source l3 such as a halogen lamp connected to a C power supply l2 is irradiated via a condenser lens l4, a field lens 15, and an optical filter l6. After the transmitted light is reflected by the reflecting mirror 18 via the imaging lens 17, it is irradiated onto the CCD 3 line sensor 19 to read information.

This CCD 3 line sensor l9 has red, green,
Consisting of three line sensors equipped with blue on-chip optical filters, each line sensor performs main scanning, and a unit 20 to which a CCD 3 line sensor 19 is attached is moved in the main scanning direction by a stepping motor 21. Sub-scanning is performed by moving along the rail 22 in the vertical direction (direction d in the figure).

The information read by the CCD 3 line sensor 19 is output as an analog signal to the analog processing circuit 23 via the cable K, where it is subjected to DC reproduction, amplification, A/D conversion, digital processing in the digital processing circuit 24, and then interfaced. It is sent to external equipment 26 via circuit 25.

Also, a stepping motor drive circuit 27 and an interface circuit 2 for driving the stepping motor 21 are provided.
5 is connected to a controller 28, and the controller 28 performs control to synchronize sub-scanning in the CCD 3 line sensor 19 with an external device 26. This controller 28 further includes a digital processing circuit 24
, the DC power supply 12 , the autochanger drive circuit 6 , and the film detection circuit 29 connected to the sensor IO are connected, and the settings of the digital processing circuit 24 , the control of the output voltage of the DC power supply 12 , and the control of the output voltage of the DC power supply 12 based on the information from the sensor 10 are connected. The drive of the autochanger 5 is controlled. In addition, switch 41
The display unit 42 constitutes a touch panel, and the controller 28 also controls the input of operator instructions from the switch 4l and the display of information on the display unit 42.

The autochanger 5 is driven as shown in FIG.

In the figure, the lift lever 30 is located inside the reading unit 4 and the shaft 31 is
When the end 30a of the lift lever 30 is pushed down by the cam 32, the end 30b rises in the direction C in the figure, and the end 30b
Move the film F located at the end portion 30a to the supply position 9
When the force of the cam 32 is not applied, the end portion 30a is raised in the direction opposite to the B direction by a spring (not shown), and the end portion 30b is lowered, and at this time, the film F at the supply position 9 is It is dropped into the section 30b.

The cam 32 that moves the lift lever 30 up and down is linked with a feeding mechanism that feeds the tray 3 frame by frame in eight directions in the figure.
The cam 32 is rotated by the drive source 33, and the movement of the feeding mechanism 34 is controlled by a plunger (not shown) included in the drive source 33, so that the tray 3 can be rotated forward, that is, the film F can be moved forward, the tray 3 can be rotated backward, That is, the film F is moved backward. Then, an output from a sensor (not shown) that detects the phase of the cam 32 is sent to the controller 28, and based on this information, the drive source 33 controls the cam 32.
The movement of the lift lever 30 and the drive of the feed mechanism 34 are controlled by the slam of the cam 32.

As a result, the tray 3 is controlled to be fed frame by frame in the forward or reverse direction, and the film F at the supply position 9 is moved to the reading position 1.
1, and control to lift the film F at the reading position l1 to the supply position 9 are performed. Then, the tray 3 rotates by one frame and one sheet of film F is moved to the supply position 9, and this film F is fed to the reading position 1l where information is read. The film F from which the information has been read is then returned to the supply position 9. This series of operations corresponds to one revolution of the cam 32, and frame-by-frame feeding and image reading are performed by repeating this operation. Note that the tray detection circuit 43 is used to detect whether or not a tray 3 is present on the tray stand 2 and the type of tray 3 set.

Next, a procedure for registering the numbers of desired images of a plurality of films stored in the tray 3 to be read will be explained. FIG. 3 shows a touch panel screen consisting of a switch 4l and a display section 42. As shown in FIG. A display 50 "rlJnXXJ" indicates the film number to be registered on the current tray 3 (the number of the storage section of the tray 3), and the forward key 52 and return key 53 are used to operate this number. The display 5l, ro/80J, indicates the number of registered films, and indicates that 0 out of max 80 has been registered.

There are generally two types of trays 3 on the autochanger 5: one that can hold 80 films, and one that can hold 14 films.
There are some that can set 0 sheets of film.

These two types of trays have a tray detection circuit 4 due to the difference in the shape of the bottom.
The device automatically determines based on the output of step 3 and displays [xx
/80J or "xxx/140J" is displayed. After displaying the desired film number (for example, 25) on the display 50 by operating the forward key 52 and return key 53, press the registration key 5.
4, the desired film number is registered. In this case, if the 25th film has already been registered, rNo. is displayed on the display 50 as shown in FIG. 25J is displayed, and a further display 55 of ``(registration)'' is displayed, indicating that the film number ``NO. 25'' has already been registered.

Similarly, operate the forward key 52 and return key 53,
Desired film numbers can be registered for the maximum number of films that can fit in the tray. After registering as many as you need, press the exit key 57.
Press to end the registration and move to the screen for instructing the start of image reading. This registered film number is stored in the built-in memory of the controller 28. Incidentally, by pressing the cancel key 55, registration of an already registered film number can be canceled.

The process of reading the film image registered as described above will be explained using the flowchart shown in FIG. Figure 3,
After frame number registration according to the procedure explained in FIG. 4 (step ■), when a start key (not shown) is pressed (step ■), the controller 28 instructs the drive source 33 to move forward (step ■), Rotate the tray 3 one frame in the forward direction. As a result, the film F in the storage section 7 that has been moved to the supply section 9 is taken into the reading section 4.

Then, it is determined whether the film F is registered (step ■), and if it is registered, the image of the film F in the reading section 4 is read (step ■); If not, the film F is returned to the tray without a reading operation, and the tray 3 is further advanced by one frame (step 2).

After reading, the film F is returned to the tray 3, and it is determined whether reading of all registered films has been completed (step 2). If there is still some left, advance tray 3 one frame further (step ■)
, if completed, this reading process ends.

After the reading is completed, it is determined whether the last film number read is in the first half or the second half of the tray (step 2).

That is, if the maximum number of films that can be stored in the tray is 80, it is determined whether A≧40 or A<40 for the final film number A. Then, when A≧40, move forward, A
When <40, control is performed to move backward and return the tray to the O position more quickly to complete the process.

That is, when A≧40, the tray is moved forward one frame at a time (step ■), and when A<40, the tray is moved backward one frame at a time (step 0), and in both cases, tray 3 comes to position O. The process advances to (step 0, ■) and ends the operation.

In this way, by being able to specify the number of multiple image films that you want to read, you can register as many film numbers as you need during the initial settings, and then just press the image reading start key and the registration will be automatically performed. Read only the film that has been read and finish. In addition, all you need to do is make the initial settings, and the rest is done automatically by the device, making it easy to use without any user intervention. Furthermore, since only the numbers are registered, there is no need to take the trouble to advance the film images one by one, and if there is a correspondence between frame numbers and film images, registration can be completed in a very short time.

As described above, by registering one or more desired film numbers among the plurality of films stored in the tray 3, a reading operation is performed that skips unnecessary frames of film. Therefore, it is possible to efficiently read only desired film images from a plurality of films without having to take the trouble of successively storing only desired films in the tray.

[Second Embodiment] FIG. 6 is a diagram showing a display screen of a touch panel in a second embodiment of the present invention. rllhl3~Na 1 7
The designation J 60 will generally be described as rkA-1kBJ. Also, the maximum number of films that can fit into tray 3 is T m a
Let it be x.

In the mode of this second embodiment, the film image to be read is registered by the range on the tray 3. First, set the value of A. That is, the user operates the forward key 62 and the return key 63 to determine the desired leading number.

This process is shown in FIG. When a key is operated, it is determined whether the forward key 62 or the return key 63 has been pressed (steps (LL!), (■)). When the feed key 62 is pressed, it is determined whether the displayed value of A is Tmax (step), and if it is not, the value of A is
Add 1 to the value of (step (.TEE5)) and display the result on the display 60. On the other hand, if the value of A is
If it is equal to x, there is no higher value, so set the value of A to O
(step (D)).Similarly, if the return key 63 is pressed, it is determined whether the displayed value of A is O (step (D)), and if it is not, the value of A is Subtract 1 and display (step (ko), if A=O, T m
a x is displayed (step (D)).

The value A of the first film number determined in this way is set by pressing the registration key 64, and then the operation moves on to setting the value B. By similarly setting the value of B, the range of image reading is determined as film number A-B. If you wish to correct it, press the cancel key 65,
The value of B will be cleared to 0, and the settings will have to be redone. As mentioned above, the display 61 displays the number of registered sheets relative to the maximum number of sheets stored in the tray, and in the example shown in FIG.
Film numbers 13 to I7 are registered, so display 6l.
becomes f-5/80J.

Film images are read from the range thus set in the same manner as in the previous embodiment. If the film is missing within the range, the film detection circuit 29 automatically controls the camera to proceed to the next frame without reading the image of that frame.

Figures 8 and 9 are schematic diagrams of the tray viewed from above.
The figure shows the film number range specified as 21-35,
FIG. 9 shows a pattern in which the range of film numbers is specified as 51 to 65. In the case of Fig. 8, the tray 3 moves forward from the position number O at first, and after sequentially reading images from the 21st to the 35th sheet, the tray 3 is moved backward and returned to the O position. Fastest. In addition, in the case of FIG. 9, it does not take much time to move the tray 3 backward and read images from the 65th sheet, and after reading the 51st sheet, move the tray 3 forward and return it to the O position.

The sequence for increasing the speed will be explained using FIG. The aforementioned range specification N (LA-NαB is used.

First, in order to find the distance between the value of A and the 0 position of tray 3 (hereinafter referred to as home position HP), the value of A is compared with 40 (step (◎l). This is a tray that can hold up to 80 sheets. In the case of using a tray that can accommodate 140 sheets, the number is 70. Hereinafter, the explanation will be made assuming that a tray that can accommodate 80 sheets is used.

If A is less than 40, put the value of A directly into C (step (■)); if A≧40, put the value of 80 - A into C (step (■)). and the distance from the tray HP.

The same process is performed for the value of B (step (1, (DG)
, C5D>, the distance between B and the tray HP is entered as the value of D. After that, C and D are compared (step (■)). This determines which of the first value A and the last value B of the registration range is closer to the tray HP. If A is closer, first move forward and Images are read sequentially from B to B (step (Q. (fi)). On the other hand, if B is close, move backwards and
Read the image from to A (step C■).CE
W).

After that, in the same way as in the previous embodiment, it is determined whether the position at the end of reading is closer to the forward side or the backward side with respect to the tray HP (step (mouth), (mouth)), and the tray 3 is placed on the closer side. Return to the tray HP by moving (step (L)
L4). C5), end.

This operation can be controlled in a similar manner not only when specifying a range, but also when one or more film images are registered separately.

If the configuration is configured so that the corresponding film images are registered while operating the tray and checking each film one by one on the viewer in accordance with the operations of the forward key and return key in registering the film number explained above, the recognition of the image to be registered is possible. Registration is easy to understand and difficult to make mistakes.

Furthermore, after registration, the system automatically reads the registered number of images with a press of the start key, and the user is not required to perform any operations during this time.

〔Effect of the invention〕

As described above, according to the present invention, by registering a desired image in advance, it becomes possible to read the desired image efficiently.
