Therefore, the same components as those shown in FIGS. 1 and 2 are designated by the same reference numerals, and the duplicated description will be omitted.

Next, the operation will be described. First, the procedure for assembling the input / output device will be described. In FIGS. 1 and 2, first, a plurality of heating resistors 121 are formed in a desired pattern on an insulating substrate, and then a protective film (not shown) is applied to manufacture the heating substrate 101. A drive circuit 131 is mounted on the heat generating substrate 101,

Next, the amplifier 211 formed of a chip IC is mounted at a designated position on the sensor substrate 181 and wire-bonded, and the signal take-out portion 161, the signal take-out portion 231 and various parts such as a chip resistor are respectively heated. The board 101 and the sensor board 181 are connected by soldering. Next, the heat generating substrate 10 of the support 171
1 and the signal processing board 141, the sensor board 181 is attached to the surface opposite to the attachment surface by a double-sided tape.

Subsequently, with respect to the resin frame 191 in which the light source 21A and the rod lens array 22A are inserted, the glass plate 20A and the heat generating substrate 1 attached to the support 171 are attached.
01, the signal processing board 141, and the sensor board 181 are attached. By doing so, an input / output device is formed.

On the other hand, in this input / output device, the document 18 is conveyed to the image forming portion on the glass plate 20A by the roller 19 so that characters, image information, etc. of the document can be obtained.

To record.

A roller 19 is installed to adjust the image forming position of the original 18 in the vertical direction and to convey the original, and the Joule heat generated from the heating resistor 121 is efficiently transmitted to and recorded on the recording paper 23. A roller 24 is installed also for transporting the paper 23. By thus integrating the reading unit A and the recording unit B on the upper and lower surfaces of the support base 171, it is possible to achieve a compact structure and a low cost without mutual interference.

Example 2. Although the heating resistor 121 is formed on the flat surface (the lower surface in FIG. 3) of the heat generating substrate 101 which is an insulating substrate in the above-described embodiment, as shown in FIG. 4, the end surface (side surface) of the heat generating substrate 102 is shown.

As a method of forming the heating resistor 121 on the end surface of the heating substrate 102, for example, a manufacturing method by spherical exposure is adopted, and as the heating resistor 121 and a protective film (not shown), a thick film material is used. Since it is a strip-shaped resistor, it is printed by direct drawing.

Since such a thick film material requires a firing process at 800 ° C. or higher, a ceramic substrate coated with glass is used as the insulating substrate for forming the heat generating substrate 102. Common connection wire 1 shown in FIG.
11 is used to form a pattern on one side.

By configuring the sensor substrate 181 as shown in FIG. 2, the document 18 is mainly conveyed in a plane, but here the recording paper 23 can be conveyed at a right angle, and the reading unit and the recording unit can be used. Since the parts are integrated, the transportation space is small.

No. 03, the signal processing board 143 is connected by thermocompression bonding of a wire, and the signal take-out portion 162 is composed of an FPC (flexible printed circuit). Therefore, since the support base 171 is not necessary, the structure can be made more compact.

Example 4. In FIG. 6, the supporting base 171 is removed, and the heat generating substrate 103 shown in FIG. 5 is attached to the side surface of the resin frame 191 with a cured resin. As a result, the heating resistor 12 becomes the glass plate 2
The original document 18 and the recording paper 23 for reading can be conveyed on the same plane as 0A.

Example 5. FIG. 7 shows the signal processing plate 1 shown in FIG.
43 is removed, and the drive circuit 131 on the heat generating substrate 104 and the signal take-out portion 162 are directly connected by thermocompression bonding of wires, thereby further reducing the size and cost of the structure. be able to.

Example 6. FIG. 8 shows another embodiment of the present invention. In the embodiment of FIGS. 1 to 3, the signal processing board 141 and the sensor board 181 are made of the same base material, and the heat generation board 105 is provided as an insulating board on the support 172. However, here, the drive circuit 131 is used as a mounting plate. Sensor board 182
In order to prevent the reading position and the recording position where the heating resistor 121 is located from approaching each other.

That is, since the resin frame 191 comes around the reading position as shown in FIG. 9, the conveyance path of the recording paper 23 becomes a problem. Therefore, the heat generating substrate 105 is formed on the end face to secure the transport path. Here, the signal take-out portion 163 is taken out from the end portion of the sensor substrate 182.

Example 7. In FIG. 10, the heat generating substrate 106 supported on the support 173 is formed in a flat surface, and the sensor unit and the signal processing unit are divided in order to secure the conveyance path of the recording paper 23, and the sensor substrate 183 is shown in FIG. An input / output device is constructed by bending it into a.
FIG. 11 shows the configuration of the input / output device after it is mounted on the resin frame 191. Here, the signal extraction unit 16
