Description

[Detailed description of the invention] Industrial applications The present invention relates to a printer with a copying device.

BACKGROUND OF THE INVENTION Conventionally, a copier that can be used as a printer,
There are printers that are connected to an image scanner and print based on data read by the image scanner.

Problems to be Solved by the Invention The former has a printing unit and a reading device built into a common housing, and in addition to the drive mechanism that transports paper for printing, there is also a drive mechanism that moves the image reading unit and the document relative to each other. A drive mechanism must be provided to move the device, making the structure complicated and large.

The latter requires the purchase of an image scanner in addition to a printer, which has the disadvantage of increasing the financial burden on the user.

Means for solving the problem A paper feed section and a printing section are provided in the paper path for conveying the paper,
An image reading section whose output side is directly or indirectly connected to the printing section and optically reads an image of a document is provided in the paper path.

Therefore, the image reading section reads the image of the document in the process of feeding the document along the paper path by the paper feeding section, and then the image reading section reads the image in the process of feeding the document along the paper path by the paper feeding section. The structure is made smaller and simpler by printing an image by the printing unit based on the data, and by conveying the document and paper along a common paper path and by a common paper feeding unit.

Example An embodiment of the present invention will be described based on the drawings.

1 is a housing, and the second housing 1 is provided with a printing section 2. The printing unit 2 includes a rotatable photoconductor 3 driven by a motor (not shown), a charger 4 that applies electric charge to the outer periphery of the second photoconductor 1, and a photoconductor 3 based on a print signal.
an exposure unit 5 that scans a beam with a beam, a developer 9 in which a magnetic roller 8 is attached to a toner box 7 containing toner 6, a transfer charger 1o, a pair of heating and fixing rollers 11, and the outer periphery of the photoreceptor 3. It consists of a toner receiver 13 that holds a blade 12 that comes into contact with the toner, and a lamp 14 that irradiates the entire outer periphery of the photoreceptor 3 with light.

Further, a cassette case 16 for holding sheets of paper 15 in a stacked state is removably housed in the lower part of the housing 1, and a manual feeding section 17 for inserting sheets of paper one by one is provided on the front surface. Then, the paper starts at the exit of the cassette case 15, merges with the end of the manual feed section 17 on the way, passes between the photoreceptor 3 and the transfer charger 10, and then passes between the heating and fixing rollers 11. A passage 18 is provided. Further, along this paper path 18, a paper feeding section 19. '20, 21.
22, 23, and 24 are arranged. The paper feeder 19 is a roller driven by a motor, and the uppermost layer of paper 15 in the cassette case 16 is pushed up from below and comes into contact with the paper feeder 19 . Other paper feeding units 20, 21, 22,
23 and 24 consist of a roller driven by a motor and a roller elastically in contact with this roller.

Further, the paper path 18 is provided with an image reading section 25 located between the paper feeding sections 21 and 22. The image reading unit 25 has an L that illuminates the document passing through the paper path 18.
ED2B, lens 27 that passes reflected light from the original, and C
It consists of an OD image sensor 28. Also, paper path 1
8 is provided with a detector 29 located between the image reading section 25 and the paper feeding section 21 and a detector 3o located near the heat fixing roller 11.

In such a configuration, when the mode switch (not shown) on the front of the housing l is set to copy mode and a document is inserted from the manual feed section 17, the document is directed toward the photoreceptor 3 by the paper feed section 21, 22. will be sent.

At this time, the detector 29 detects the original, and the image reading section 25 starts operating based on this detection signal. That is, LED
26 illuminates the original, and the lens 27 CODs the image of the original.
An image is formed on the image sensor 28. The output of this COD image sensor 28 is stored in a memory (not shown) connected to a control row (not shown) of the exposure section 5. Further, the original is fed by paper feeding sections 21, 22, 23, and 24 and discharged onto the tray 31. During this ejection process, the detector 30 detects the passage of the document, and in response to this detection signal, the current supply capacity to the heater in the heating and fixing roller 11 is increased, and the temperature of the heating and fixing roller 11 is raised to about 180 degrees. On the other hand, when the detector 29 detects the document and a certain period of time has elapsed, the paper feed section 19 rotates and pulls out the paper 15 from the cassette case 16. When the paper 15 is fed to the photoreceptor 3 by the paper feed sections 20, 21, 22, the detector 29 detects the paper 15, and the printing section 2 starts operating in response to the second detection signal. That is, the photoreceptor 3 begins to rotate, and during this rotation, the charger 4 applies charges to the outer periphery of the photoreceptor 3 to form a charged layer, and exposure is performed based on the output of the memory that stores the reading data of the original. The unit 5 scans the charged layer with a beam of light to form an electrostatic latent image, and the developer 25 develops the electrostatic latent image.
The transfer charger 1o transfers the toner image onto the paper 15, the heat fixing roller 11 fixes the transferred image on the paper 15, and the paper feed section 24 discharges the paper 15 onto the tray 31.

On the other hand, the remaining toner adhering to the photoreceptor 3 is removed by the blade 1.
2 scrapes the toner onto the toner receiver 13, and the lamp 14 scrapes the toner onto the photoreceptor 3.
The entire outer periphery of the image is exposed to light to erase the electrostatic latent image.

In this way, the original and the paper 15 can be fed along the common paper path 18 by the common paper feeding sections 21, 22, 23, 24, which simplifies the structure and reduces the internal structure. It is possible to reduce the space and achieve miniaturization.

In addition, by storing data from the image reading unit 25 in the memory and inputting data from an external input device such as a personal computer into the memory, a usage pattern in which other image information is combined with the content of the original and printed out is possible. You can also choose. Furthermore, by installing the image reading section 25 downstream of the photoreceptor 3, the data of the document is read downstream of the paper path 18, and this read signal is directly transmitted to the exposure section 3.
can be input and printed simultaneously on the subsequent paper 15. In this case, no memory is required.

Effects of the Invention Since the present invention is constructed as described above, the image reading section reads the image of the document in the process of feeding the document along the paper path by the paper feeding section, and then the image of the document is read by the image reading section. During the process of feeding by the feeding unit, the printing unit can print an image based on the data read by the image reading unit, and by transporting the document and paper along a common paper path and by a common paper feeding unit. Therefore, it has the advantage of being able to downsize and simplify the structure.
