Next, the composite terminal device 30, which is a feature of this embodiment, will be explained in more detail with reference to FIGS. 2 and 3.

This composite terminal device has a print head 32 as described above.
It has a head module 31 in which a sensor head 33 and a sensor head 33 are integrated. The print heads 32 are arranged in one row.
It can print individual dots, and may be a pin head for dot printers or a thermal head for thermal printers. The sensor head 33 is connected to this printer head 32.
It is composed of a COD image sensor with n pixels corresponding to .

This head module is attached to a gear rod 100 of a head drive mechanism (not shown) in the composite terminal bag W30. By rotating this gear rod 100, the head module 31 moves in a direction perpendicular to the direction in which the paper 34 moves. As a result, characters, figures, etc. can be recorded line by line on the paper 34, or characters on the paper 34,
It is possible to read figures, etc. line by line. When recording or reading for one line is completed, the head module 31 performs a line feed. Line breaks are made at predetermined intervals, but considering recording or reading graphics, the print head 32
Also, the paper 34 is fed by the width of the dot row and pixel row of the sensor head 33 at the time of line feed.

When recording characters, graphics, etc. using the computer head 32, the data is sent from the CPU 11 via the data bus 4, and after being temporarily stored in the data buffer 103, it is latched into the latch register 101.

When the head module 31 reaches a predetermined position on the paper 34, the driver 104 drives the bins of the print head 32. When the data is ``1'', a dot is placed on the bin, but when the data is ``0'', no dot is placed. After printing one row, the head module 31 is moved to the left or right by one bit, and the next row of data is printed in the same way.

When the sensor head 33 reads characters, figures, etc. on the paper 34, the head module 31 is first moved to a predetermined position, and the sensor head 33 reads the brightness and darkness on the paper 34. Thereafter, the sensor head 33 functions as a CCD shift register and transfers the read data to the data buffer 1.
03 and save. Note that the data output bit by bit from the sensor head 33 is input again to the first bit of the sensor head 33 via the buffer 102.

Read data stored in data buffer 103 is output to data bus 4.

Next, the operation of this embodiment will be explained. The multifunctional information processing apparatus according to this embodiment has various functions such as a computer function, a word processor function, and a facsimile function.

When this multi-function information processing device is used as a computer, the CPU 11 performs program control as a computer. The main storage device 20 stores a computer operating system, an I10 control program, application programs, and the like. A floppy disk drive 40 and a hard disk drive 70 are used as auxiliary storage devices. The operator inputs commands and data using the keyboard 61 and mouse 62, and displays them on the display 6.
Outputs the necessary information to 0.

Next, when using it as a Japanese word processor, the basic usage conditions are the same as when using it as a computer. However, a word processor program such as kana-kanji conversion is stored in the main storage device 20. Furthermore, in order to display kanji on the display 60 or the multifunction terminal device 30, it is necessary to store kanji patterns in the main storage device 20.

Next, the case of using it as a facsimile will be explained.

When image information is received from the external line 50, the modem 51
The image data is demodulated and converted into digital image data, and the image data is sent to the data bus 4 via the communication controller 52. This image data is once stored in the main storage device @20 and then stored in the floppy disk device 40 or the hard disk device 70. The stored image data is recorded on paper using the print head 32 of the multifunction terminal device 30.

On the other hand, when transmitting an image of characters, figures, etc. on the paper 34, this image is read by the sensor head 33 of the compound terminal @30, digitized, and stored in the main storage device 20. This stored data is transmitted to an external line 50 via the data bus 4, communication controller 52, and modem 51.

Note that when receiving, the image may be printed out immediately without temporarily storing the image data in the main storage device 20, and when transmitting, the image information may be immediately transmitted to the external line 5o.

Also, image information is usually transmitted and received using compressed codes to increase transmission efficiency. Therefore, encoding or decoding is performed under the control of the CPU 10.

Even when this multi-function information processing device is used as a computer or word processor, it is possible to receive calls as a facsimile. In this case, if the multifunction terminal device 30 is being used as a printer, the received image data is temporarily stored in the floppy disk device 40 or the hard disk device 70, and printed out when the multifunction terminal device 30 is free. These multi-functional task controls are
This is done by the CPUO operating system.

Next, multifunction information processing S! according to the second embodiment of the present invention!
The main parts of the multifunction terminal device 30 will be explained using FIGS. 4 to 6. The difference from the first embodiment is that the sensor head 32 of the head module 31 is composed of two rows of CCD line sensors 32a and 32b. That is, a CCD line sensor 32a provided at a position corresponding to the printer head 32, and a CCD line sensor 32 that is shifted by a half dot from this CCD line sensor 32a.
b constitutes a sensor head 32.

As shown in FIG. 5, two rows of CCD line sensors 32a,
32b to buffer F102a.

102b is provided. CCD line sensor 32a
, 32b are summed by an adder 105, and the final read data determined by the sum is stored in the data buffer 103.

In this way, the sensor head 33 is offset by half a dot.
e Since the readings and additions are made using two rows of COD image sensors, one COD image sensor is used as shown in Figure 6.
Even if there is a dot 106 to be read between the pixels of the D image sensor 33b, it can be reliably read by the other COD image sensor 33a. Suitable for reading characters, figures, etc. printed with dots.

Next, main parts of a multifunction terminal device 30 of a multifunctional information processing apparatus according to a third embodiment of the present invention are shown in FIGS. 7 and 8. The difference from the first and second embodiments is that the sensor head 33 of the head module 31 is a one-row CCD two-dimensional sensor.

A sensor head 33 consisting of a (,002-dimensional sensor with mxn pixels) is fixed near the print head 32, which is provided on the gear rod 100 and moves left and right.

A selector 107 controls which column of read data from the sensor head 33 is stored in the data buffer 103. The selector 107 sequentially selects a pixel column consisting of n pixels, for example from left to right, and stores the read data in the data buffer 103.

Since the sensor head 33 is provided for one line in this way, high-speed operation of reading the image on the paper one line at a time is possible.

FIGS. 9 and 10 show the main parts of a multifunction terminal device of a multifunctional information processing apparatus according to a fourth embodiment of the present invention. 1st. The difference from the second and third embodiments is that the sensor head 3
1 print head 32 and sensor head 33 are both 1
The point is that the dots are arranged in a horizontal row. That is, the print head 32 is configured by arranging m dots of pins with the width of the paper 34, and the sensor head 33 is configured by a COD line sensor having m pixels. The paper 34 is one dot wide.

Since m bits of image data are handled at a time, the latch register 108 and driver 109 for recording by the printer head 32 both require m bits. Similarly, the image data buffer 110 also requires m bits.

In this way, since there is no moving part in this embodiment, images can be recorded and read at extremely high speed.

In addition to those shown in the above embodiments, other input/output devices can be added to the multifunction information processing apparatus according to the present invention. For example, if a voice input/output device is added, voice commands, data input, and voice instructions to an operator are possible. If an acoustic coupler is added, data can be input and output using a telephone line. Furthermore, if a large capacity image memory such as an optical disk is added, it is possible to store, print, and transmit large amounts of image information. In addition, it is also possible to add input devices such as a handwriting input tablet device, a kanji input tablet device, a barcode reader device, and a character reading device, and an output device such as a plotter device, a plasma display device, and a line printer device.
