Abstract

PURPOSE:To reduce the size of a device and to simplify the device by commonly using a mirror, in a reader printer having a reader function and a printer function. CONSTITUTION:During a reader function, a rotary mirror 13 is brought into a rest in a first position shown by a solid line. The image of a microfilm F is enlarged and projected to a screen 16 through the rotary mirror 13 and fixed mirrors 14 and 15 by means of a projection lens 12. During printing, the rotary mirror is rotated counterclockwise around an axis 13a. When the mirror is rotated to a second position shown by a broken line, it, reversely, is rotated clockwise. The image of the microfilm F enters a photo sensor array 17 through the fixed mirrors 14 and 15 and is read. An electric signal generated based on the read image information is transmitted to a printer and a printer image is formed on a recording sheet.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reader printer having a reader function for projecting a film image on a screen and a printer function for printing on a recording sheet.

[0002]

2. Description of the Related Art A conventional reader printer is provided with a reader optical path for projecting a film image on a screen of a reader section and a printer optical path for projecting an image receiver of the printer section, and switching each optical path by moving an optical path switching mirror. And the scanning mirror is rotated or linearly moved to scan and expose the image of the film on the image receptor.

[0003]

By the way, in the reader printer of the above-mentioned conventional example, each optical path is completely separate from the switching mirror (on the side opposite to the film side), and an extra space is required, Moreover, an optical path switching mirror and a scanning mirror are required, and the device becomes large,
In addition, the structure is complicated and the cost is increased.

It is an object of the present invention to eliminate the above-mentioned drawbacks of the prior art and to provide a reader printer which is small in size, inexpensive and simple in structure.

[0005]

In order to achieve the above object, the present invention is a reader printer having a reader function for projecting an image of a film on a screen and a printer function for printing on a recording paper, and the image of the film is provided. By rotating at least one rotating mirror and an optical sensor array arranged in the vicinity of the screen and behind the rotating mirror, and by making the rotating mirror stand still at the first position. The image of the film is projected onto the screen and rotated between the first position and the second position so that the image of the film is scanned and exposed on the photosensor array.

[0006]

In the reader printer having the above construction, the optical sensor array for receiving the image of the film is arranged near the screen and behind the rotating mirror, and the optical path is switched and scanning exposure is performed by rotating the rotating mirror. Thus, the optical paths can be made almost common, and the device can be downsized and the configuration can be simplified.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment according to the present invention will be described below with reference to FIG. In the figure, F is a microfilm,
Reference numeral 11 is a lamp for illuminating the microfilm F, 12 is a projection lens for enlarging and projecting the image of the microfilm F, 1
Reference numeral 3 is a rotary mirror that rotates and scans about the shaft 13a.
It is arranged on the optical path in front of the projection lens 12, and
Numerals 4 and 15 are fixed mirrors that face each other at substantially right angles, and are located on the optical path in front of the rotating mirror 13, 16 is a screen, and 17 is an optical sensor array that receives light from the image of the microfilm F. A large number of linearly arranged near the lower end edge of the screen 16 in the figure and arranged behind the rotary mirror 13.

In this embodiment having the above structure, the lamp 1
The illumination light flux from 1 is condensed by a condensing system (not shown) and irradiates the microfilm F, the image of the microfilm F is magnified by the projection lens 12, and the rotating mirror 13 is stationary at the first position shown by the solid line. Is reflected by. Since the rotating mirror 13 is normally fixed to the first position indicated by the solid line in the reader state where the user can read it on the screen 16, the image on the microfilm F is reflected by the fixed mirrors 14 and 15 and projected on the screen 16. It On the other hand, when the image on the screen 16 is printed, when the printer button (not shown) is pressed, the rotary mirror 13 moves to the shaft 13a.
When it comes to the second position indicated by the broken line, it starts to rotate in the clockwise direction. At the same time, the light reflected by the fixed mirrors 14 and 15 is reflected by the optical sensor array 1.
It is incident on the beam No. 7 and the reading is started. Optical sensor array 1
Since the image information read in 7 is a mirror image of the screen 16 upside down, after being stored in a memory (not shown),
The image is processed into a normal image, and an electric signal is sent to a printer such as an LBP (laser beam printer) (not shown) to form a printer image on the recording paper. When the reading is completed, the rotating mirror 13 returns to the first position (solid line) and stops. Therefore, the image of the microfilm F is projected on the screen 16 again.

With this configuration, the print optical path, which is separately provided by switching the mirrors as in the conventional example, can be shared with the reader optical path, and the photosensor array is located near the screen and behind the rotary mirror. Since it is placed in the dead space of the device, the device becomes very compact, and the switching mirror, which was necessary for the printing optical path, is not required and the cost can be reduced. Further, since the mirror of the reader optical path and the mirror of the print optical path are common, the alignment of the image of the microfilm F can be adjusted by adjusting the mirror, and the adjustment time can be shortened and the accuracy can be improved.

FIG. 2 shows a second embodiment of the present invention. For simplification of description, the same parts as those of the first embodiment shown in FIG. 1 are designated by the same reference numerals, and only different points will be described. In this embodiment, a fixed mirror 18 is arranged immediately in front of the photosensor array 17, and the reflected light from the fixed mirrors 14 and 15 is incident on the photosensor array 17 via the fixed mirror 18. The other structure is exactly the same as that of the first embodiment. In the projection system having this configuration, the image on the screen 16 and the image read by the optical sensor array 17 coincide with each other, so that the image signal can be directly stored in the memory without being a mirror image.

FIG. 3 shows a third embodiment of the present invention. This embodiment is a modification of the first embodiment described above, in which the fixed mirror 14 is a rotatable switching mirror 14a and a conventional analog printer is provided behind the switching mirror 14a. Then, during printing, the switching mirror 14a moves to a position 14a 'shown by a broken line which is out of the reflection optical path of the rotating mirror 13a, and at this time, the film F
The image is scanned and exposed on the photosensitive drum 20 via the projection lens 12, the rotating mirror 13a, and the analog fixed mirrors 19a and 19b. When the film image is read and transmitted by facsimile, the switching mirror 14a moves to the position indicated by the solid line, and the film image is projected onto the optical sensor array 17 via the projection lens 12, the turning mirror 13a, and the mirrors 14a and 15. The rotary mirror 13a is rotated for scanning exposure.

[0012]

As described above, according to the present invention, the optical sensor array for receiving the image light of the film is arranged in the vicinity of the screen and behind the rotary mirror, and the rotation of the rotary mirror switches and scans the optical path. By performing the exposure, there is an effect that the entire apparatus can be made compact and cost can be reduced, and the optical axis can be easily adjusted to improve the accuracy.
