Since the manual copying device copies the part where the light source is off as a white outline, the image of only the part where the light source is on is copied onto a sheet of paper and then ejected.

[gl Embodiment FIG. 2(A) is a schematic structural diagram of a manual copying apparatus which is an embodiment of the present invention. The main body 1 of the apparatus is formed in the shape of a rectangular parallelepiped with an open bottom, and a roller 3 is provided at the bottom opening to regulate the direction of copying and to feed thermal paper, which is copy paper. A portion of this roller 3 is exposed to the outside of the apparatus main body 1. Further, in the opening of the device body 1, a CCD array 9 which is an image sensor array and an LED array 10 that irradiates light toward the image detection position of the CCD array 9 are installed parallel to the axis of the roller 3. . The CCD array 9 captures the L B reflected from the surface of the original.
The light from the D array 10 is received. On the other hand, a rotational angle encoder 2 having a large number of protrusions on the circumference is attached coaxially with the roller 3, and a magnetic sensor 7 for detecting the protrusions is provided near the circumference of the rotational angle encoder 2. The magnetic sensor 7 detects the rotation angle of the roller 3, that is, the scanning distance of this manual copying device, by detecting the protrusion. An auxiliary roller 4 is provided inside the apparatus main body 1 in contact with the roller 3. Between the auxiliary roller 4 and the roller 3, thermal paper fed out from an intermediate thermal paper roll 5 provided above is passed. A thermal head 8 for printing an image on the thermal paper and a platen 8a for bringing the thermal paper into contact with the thermal head 8 are provided between the thermal paper roll 5 and the auxiliary roller 4. 8 and platen 8a.

Furthermore, the tip of the thermal paper 5 comes out of the device through a slit 6 provided at the top of the device body 1. Furthermore, a slide volume 1) is attached to the top of the device body 1, and its slide knob lla is exposed to the outside of the device. exposed and made scannable.

This manual copying device copies a document by manually scanning it in the direction of the arrow in the figure. During this scanning, the thermal paper 5 is fed out by rotating the roller 3 that is in contact with the original.
The image read by the CCD array 9 is copied by the thermal head 8.
