Abstract

PURPOSE:To obtain an output in a prescribed polarity direction at all times by sensing the direction of rotation of a drive roller and using a microswitch so as to give a command to a CPU that read information is outputted in the opposite order to that stored in a RAM when the subscanning direction of read information is reverse. CONSTITUTION:A microswitch 20 is provided in the vicinity of a drive roller 3, the direction of rotation of the roller 3 is sensed by ON/OFF of the switch 20 to identify the subscanning direction of read information. At first, when the information is read from the left to the right in the subscanning direction, the rotation of the roller 3 is the forward direction, the switch 20 is opened, and the information in the order of normal reading is sent and outputted. When the information is read from the right to the left in the subscanning direction, the rotation of the roller 3 is the reverse direction, the switch 20 is closed, and the information is outputted in the reverse sequence to that stored in a RAM 6 through a command to a CPU 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual scanning type information reading and copying apparatus.

[0002]

2. Description of the Related Art A conventional manual scanning copying machine has a structure as shown in FIG. That is, FIG. 3 shows an outline of a conventional manual scanning type copying machine. A reading section 2 for reading information on a document surface 1 and a driving section 4 for rotating a driving roller 3 as the copying machine moves. A printer unit 5 for printing the information read by the reading unit 2, a RAM 6 for storing the information of the reading unit 2, and a CP for controlling the entire copying machine.
It consists of U7.

In this conventional manual scanning copying machine, the sensor section 8 of the reading section 2 is arranged on the reading original surface 1 from left to right.
That is, the image is detected by moving in the sub-scanning direction. Reference numeral 9 is a light source of the reading unit 2, and 10 is a SELFOC lens. At the same time when the reading unit 2 detects an image, the drive roller 3 rotates, and the encoder gear unit 11 and the photo interrupter 12 synchronize with each other. Then, the optical level signal detected by the sensor section 8 is converted into an electric level signal by the CPU 7, and the signal is transferred by the thermal head 13 of the printer section 5.

[0004]

However, in this conventional method, when the sub-scanning direction is moved from right to left in FIG. 3, the read information is detected from the opposite side and is output via the printer unit 5. The image obtained has the drawback that it can be obtained as a mirror image of the read information.

That is, as shown in FIG. 4 (a), if the reading sub-scanning direction is taken from left to right, the same information as the read information can be obtained as the output through the printer unit 5, but FIG. As shown in (b), if it is taken from right to left, it will be output as a mirror image.

This is because in the step of processing and transmitting the read information, the information stored in the RAM 6 is transmitted to the CPU 7 in the order in which the information is read, and the printer unit 10 outputs the information as it is.

The present invention has been made to solve the above problems, and provides a manual scanning type copying machine which does not print a mirror image of the read information via the printer unit even if the sub-scanning direction is reversed from left to right. It was made for the purpose of providing.

[0008]

In order to solve the above-mentioned problems, the present invention comprises a reading section for reading information on the surface of an original,
A drive unit that rotates and synchronizes with the drive roller as the copying machine moves, a printer unit that prints information read by the reading unit, and a RAM that stores information of the reading unit.
The CPU that controls the entire copying machine and the CPU that senses the roller rotation direction of the drive roller and outputs the read information in the reverse order of the information stored in RAM when the sub-scanning direction of the read information is opposite. It has a micro switch that gives command.

[0009]

According to the present invention, when the sub-scanning direction is positive, the rotation direction of the driving roller is positive, the micro switch is turned off, and the read information is normally output from the printer unit in the order described above. However, when the sub-scanning direction is reverse, the rotation direction of the drive roller is reverse rotation, the micro switch is turned on, and the read information is stored in the RAM.
The CPU 6 is instructed to output the data in the order reverse to that stored in 5.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The same components as those of the conventional copying machine are designated by the same reference numerals and the detailed description thereof will be omitted.

The present invention is different from the conventional copying machine in that the micro-switch 20 is provided in the vicinity of the driving roller 3 as shown in FIG. This is a point configured to detect the ON / OFF state of (1) to identify the directionality of the read information in the sub-scanning direction.

Next, the operation of the configuration of this embodiment will be described. First, when the sub-scanning direction is taken from left to right, the rotation direction of the drive roller 3 is forward rotation (clockwise), the microswitch 20 is turned off, and the normally read information is transmitted and output in order. However, when the sub-scanning direction is taken from right to left, the rotation direction of the drive roller 4 becomes reverse rotation (counterclockwise) and the micro switch 20 is turned on to reverse the order in which the read information is stored in the RAM 6. The CPU 7 is commanded to output.

Further, the interlocking mechanism of the micro switch 20 with respect to the drive roller 3 will be described in detail. As shown in FIG. 2, as the drive roller 3 rotates, the felt 21
Also, the drive roller 3 rotates normally as it hits the rib 25 provided at a position symmetrical to the micro switch 20 at the time of forward rotation by the switch plate 24 that is interlocked with the roller shaft 23 by the spring 22.
To stop. Further, during reverse rotation, the switch plate 24 stops at the same time when the micro switch 20 is turned on, and during the reverse rotation, the micro switch 20 is constantly applied with a constant force.
Press and hold to keep ON, unless it is rotated forward, OF
The mechanism does not become F. As described above, when the microswitch 20 is ON, the CPU 7 outputs the information stored in the RAM 6 as described above in the reverse order of reading.

[0014]

The present invention detects the roller rotation direction of the drive roller near the drive roller and reverses the order of accumulating the read information in the RAM when the sub-scanning direction of the read information is opposite. By providing the micro switch for giving the command to the CPU to output the output, it has an excellent effect that the output in the constant direction can always be obtained regardless of the directivity in the sub-scanning direction.
