By connecting this to the controller unit 2, advanced information input processing becomes possible.

The lower part of FIG. 1 is a printer unit 3 for recording a color digital image signal output from the controller unit 2 on paper (recording paper). As the printer unit 3, for example, a full-size printer using a bubble-jet type recording head is used.
A color ink jet printer can be used.

The two parts 1 and 3 described above are separable and can be installed at remote locations by extending the connecting cable.

B. Film Projection System The scanner unit 1 can be equipped with a projection exposure unit (film projector) for projecting a film. FIG. 2 shows a projector unit 81 serving as a projection exposure unit for the scanner unit 1.

FIG. 5 shows a schematic configuration example of the film projection system of FIG. As shown in FIG. 5, the film image (projected image) projected from the projector unit 81 is reflected by the reflection mirror 80 and reaches the Fresnel lens 83. The Fresnel lens 83 converts this image into parallel light, and
Image on top. Thus, the image of the negative film or the positive film set in the film holder 82 is
Since an image is formed on the platen glass 17 by the projector unit 81, the reflection mirror 80, and the Fresnel lens 83, the image can be read by the CCD (charge coupled device) unit 18 of the photoelectric conversion means in the same manner as the reading of the document by reflected light. .

Here, the projector unit 81 is a halogen lamp
90, a reflection plate 89, a condenser lens 91, a film holder 82, and a projection lens 92. The direct light emitted by the halogen lamp 90 and the reflected light by the reflector 89 are condensed by the condenser lens 91 and reach the window 93 of the film holder 82 (see FIGS. 3 and 4). Film holder 82
Has a window 93 slightly larger than one frame of a negative film or a positive film, so that the film can be mounted inside with a margin.

The projection light reaching the window 93 of the film holder 82 is transmitted through the film mounted therein to obtain a projection image of the film. The projection image obtained in this manner is
After being optically enlarged by the reflection mirror 80 and turned by the reflection mirror 80, the light is converted into a parallel light image by the Fresnel lens 83. This image is stored in the CCD unit 18 inside the scanner 1.
And converts it into an electrical image signal (video signal).

D. Operation Procedure FIG. 7 shows a control procedure previously stored in the program ROM in the control unit 107. Next, a control procedure according to the present invention performed by the control unit 107 will be described with reference to the flowchart of FIG.

When the power of the device is turned on (ON), step SP10 is first performed.
Initialize with 0. Next, in step SP101, it is determined whether or not the start key 87 for instructing the start of the copying operation has been pressed. If the start key 87 has not been pressed, it is determined whether or not the projector key 86 for selecting a projector has been pressed in step SP102. It is determined whether or not the projector mode has been set. If the projector mode has not been set, the projector mode is set in step SP105. If the projector mode has been set, the projector mode is canceled in step SP104. That is, the projector key 86 functions as a changeover switch for turning on / off the projector mode. Thereafter, in any case, the process returns to step SP101.

On the other hand, if the projector key has not been pressed in step SP102, it is determined whether or not another key has been pressed in step SP106, and if another key has been pressed, it has been pressed in step SP107. Set the copy mode according to the key. The mode settings include, for example, copy sheet selection, magnification setting, and number setting. If no other key is pressed, nothing is performed, and in any case, the process returns to step SP101.

Next, if the start key 87 is depressed in step SP101, the process proceeds to step SP108 to determine whether or not the projector mode is set. Similarly to the above, the image of the original is copied by the reflected light placed on the original platen glass 17, and the process returns to step SP101.

If the projector mode is set in the above-mentioned step SP108, a copy of the projection original image from the projector 81 is made in steps SP110 to SP114.
Return to SP101. Here, first, in step SP110, the longitudinal direction (mounting direction) of the original film is determined according to the longitudinal direction (setting direction) of the copy sheet to be printed out. FIG. 8 shows that when the A4 size paper 20 is set in the paper cassette in the horizontal direction, the projector image projection area 22 is set in the horizontal direction in the same direction as the longitudinal direction of the original table glass 17, and 100% original copy is performed. It shows the situation. At this time, the projector image projection area 22 is A4 size. On the other hand, FIG. 9 shows that when the A3 size paper 21 is in the portrait orientation, the projector image projection area 22 is also in the portrait orientation.
5 shows a state in which an enlarged copy of% is performed. As described above, whether the projector projection area 22 is oriented vertically or horizontally within the frame of the Fresnel lens 83 is determined by mounting the filter holder 82 horizontally on the projector unit 81 or mounting vertically. Can be done with The direction of the original film is determined by the control unit 107 based on parameters such as editing of the shape (particularly the direction) of the copy sheet, the vertical magnification, the horizontal magnification, and the rotation as described above.

Next, in Steps SP111 and SP112, it is determined whether or not the film holder 82 containing the original film is mounted in the correct direction based on the sensor outputs of the holder sensors 94 and 97. In step SP113, a projection original image from the projector 81 is copied. After that, the process returns to step SP101.

On the other hand, if the film is not mounted at all or is mounted in the wrong direction, step SP114
In step (1), a message is output to the LCD display unit 84 so that the original film is loaded in the correct direction. That is, at this time, if the orientation of the film has been determined to be portrait in step SP110, the LCD display unit 8 shown in FIG.
In FIG. 4, a message such as "Please attach the film holder vertically" is displayed for a few seconds. On the other hand, if the orientation of the film is determined to be landscape in step SP110, as shown in FIG. A message such as "Please attach the film holder aside" is displayed on the LCD display 84 for several seconds. After that, without performing the copying process, step SP
Return to 101.

In the present embodiment, if the orientation of the film mounted on the film holder 82 does not match the setting direction of the copy sheet, it is not appropriate to perform the copying process. At this time, a warning message is displayed on the LCD display unit 84. May be displayed, and the operator may determine whether to continue the copying process by using the continuation key.

In this embodiment, the direction of the film is determined according to the direction of the copy paper in the copying machine. However, when a single reader (reading device) is used as an image reader of the host computer, the image requested by the host computer is not required. The orientation of the film can be determined according to the orientation of the size.

[Effects of the Invention] As described above, according to the first embodiment of the present invention,
Since the mounting direction of the film to the film holder is configured to be changeable according to the setting direction of the recording medium in the cassette, the mounting direction of the film can be adapted to the setting direction of the recording medium, and therefore, The image on the film can be properly recorded on the recording medium.

According to the second aspect of the present invention, the mounting direction of the film to the film holder is detected, and whether the detected mounting direction of the film matches the setting direction of the recording medium in the cassette is determined. It is possible to judge and display the judgment result, so it is easy to recognize the incompatibility between the mounting direction of the film and the setting direction of the recording medium, and it is possible to prevent image recording in such an improper state beforehand Becomes
