Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a reader printer that can be switched between a goo mode for projecting an image of an original onto a screen and a printer mode for projecting an image onto a photoreceptor.

Mi4: Toshito Nobo Traditionally, in this type of reader printer, the reader optical path for projecting an image on a microfilm or the like onto a screen and the printer optical path for projecting the image onto a photoreceptor are partially used. is being carried out. Further, in order to switch between the reader state and the printer state, a switching mirror is provided on a common optical path, and switching between the two is performed by rotating this mirror to move it in and out of the optical path.

However, it has been extremely difficult to rationally use both optical paths and effectively use the optical system to achieve miniaturization.

For example, when the switching mirror is moved in and out of the common optical path, the switching mirror becomes unnecessary when the switching mirror is moved outside the optical path and the optical path is switched, and there is a large space to accommodate the switching mirror outside the optical path. This makes it difficult to miniaturize the device. Moreover, in an apparatus that includes a part of a printer that performs slit exposure by scanning an optical system, the entire apparatus becomes large because it requires space to move the scanning optical system and space to move the switching mirror. It was even more difficult to achieve miniaturization.

SUMMARY OF THE INVENTION An object of the present invention is to provide a reader printer that can rationally serve as both a reader optical path and a printer optical path, and can effectively utilize each reflecting member at the same time as a printer, thereby reducing the size of the device.

The present invention will be explained below using specific examples shown in the drawings. 1st
The figure shows a reader printer to which the present invention is applied, in which 1 is an illumination lamp, 2 is a microfilm, 3 is a projection lens, 4 is a fixed mirror, 5 is a first device A shown by a broken line, and a first device A shown by a solid line. 2. A first mirror movable to device B, 6.
Reference numeral 7 designates a second mirror and a sixth mirror that are arranged at right angles and move together in the direction of the arrow X, 8 a photoreceptor that rotates at a constant speed in the direction of the arrow, and 9 a screen.

The first mirror 5 is connected to a drive source (not shown) such as a motor, and is rotated by this drive source around a support shaft 5A, and is located in the first position in the reader mode and in the printer mode. Time is located in the second place device B. 2nd・
The third mirrors 6 and 7 are integrally supported by a support base,
The support base is connected to a drive source (not shown) such as a motor, and is moved integrally by this drive source. In addition, when the second and sixth mirrors are in leader mode, the first position ftf (j

move back and forth between

When the reader mode is switched, the first mirror 5 is placed at the first position ff1A, and at this time, the light image of the film reflected by the mirror 4 is reflected by the first mirror 5 and projected onto the screen 9. Images on the film can be observed. 2nd and 6th mirrors 6 and 7 when in leader state
is placed in the first device C, and the second mirror 6 is placed outside the reflection optical path of the first mirror 5, which is placed in the first device A.

When the printer mode is switched, the first mirror 5 is placed in the second device B, and at this time, the optical image of the film F reflected by the mirror 4 is reflected by the first mirror 5 and placed in the first device C. It is directed to the second mirror 6, then reflected by the second mirror 6, directed to the sixth mirror 7 placed in the first device C, reflected by the sixth mirror 7, and formed into a slit shape on the photoreceptor 8. be projected.

FIG. 1 shows the printer status. When the printer mode is switched, the first mirror 5 moves to the second device B, and then when the second and sixth mirrors 6 and 7 start moving toward the second position, the image on the film is transferred to the mirror. 4.5.
Exposure to the photoreceptor 8 is started via the photoreceptor 6 and 7, and while the film is moved by a distance l to the second position, the entire image of the film to be printed is scanned and exposed onto the photoreceptor. 2nd and 6th mirror 6
- The exposure operation ends when the mirrors 7 reach the second position, after which the mirrors 6 and 7 move in the opposite direction and return to the first device C. The second and sixth mirrors 6 and 7 move at a speed synchronized with the rotation of the photoreceptor 8. In order to obtain a copy of 1 & 7, mirrors 6 and 7 are moved to the first device C after one exposure operation is completed.
When the first mirror 5 returns to the first device A, the first mirror 5 moves to the first device A and returns to the leader state. If a large number of identical copies are to be tilted, the mirrors 6 and 7 are moved back and forth between the first device C and the second position as many times as necessary. The switching mirror 5 is the leader mode.
It is effectively used even when the printer mode is shifted from F, A/), and the amount of movement can be reduced when switching modes. In addition, since the scanning mirror 6 moves within the reflection optical path of the switching mirror, it is possible to efficiently utilize the space between walls, and moreover, by reflecting only the image part of a narrow slit-shaped area out of the entire image area. Because of this, the mirror can be made smaller, and its fruiting device can be made smaller.

The photoconductor 8 is a known electrophotographic photoconductor, and a charging device, a developing device, a cutting device, a cleaning device, etc. are arranged around the photoconductor 8, and the developed image formed on the photoconductor B is is transferred to transfer paper. Since the details of some parts of the printer are well known, their explanation will be omitted. Various known printing methods can be applied to some printers.

In addition, lamp 1. Film 2. It is also possible to place the lens 6 at the dotted line position 1 and omit the mirror 4.

FIG. 2 shows another embodiment of the present invention, in which components having the same configuration and functions as those in FIG. 1 are designated by the same reference numerals. In Fig. 1, each mirror is arranged so that the technician's direction (the direction perpendicular to the plane of the paper in Fig. 1 IF-L) is parallel, but in Fig. 2, the second and sixth mirrors 6 - Although the operator's direction of the mirror 7 is parallel, the fixed mirror 4 is arranged parallel to the second and third filter mirrors 6 and 7. The first mirror 105 that receives the reflected light from the fixed mirror 4 is number one in reflecting the incident light toward the screen 9! if (broken line position; ke) and the second position ti'j that reflects the incident light toward the second mirror 6
