Abstract

PURPOSE:To take completely the synchronism of each section with simple structure by providing a roller whose outer circumference is exposed from a main body and a detector detecting a rotating angle of the roller and providing a terminal from which an output of an optical sensor and an output of the detector are outputted. CONSTITUTION:A paper feed roller 12 clips a thermosensing paper sheet 10 with a heater on which lots of heating elements are arranged in a line. Since the thermoheating paper 10 is clipped with the paper feed roller 12 and the heater 13, the thermosensing paper 10 is carried by the paper feed roller 12. Since a signal obtained by the optical sensor 5 is transmitted to the heater 13 via a circuit device 16, the heater is heated according to the output of the optical sensor 5 and picture information is recorded on the thermosensing paper 10. The output of the optical sensor 5 and a rotary encoder 9 is outputted from an output terminal 17 via the circuit device 16 at the same time. Thus, the synchronism between the relative movement between an original and the optical sensor and the relative movement between a copying medium and a copying section is taken with simple structure.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention is applicable to reading image information from manuscripts such as books and newspapers.
The present invention relates to an image information reading device that inputs information to a computer or the like, and a copying machine that copies the read information onto a copying medium.

Conventional configuration and problems Conventional image reading devices connected to fax machines and computers generally read two-dimensional image information by moving a line-type photosensor relative to the document. In order to do this, it is necessary to synchronize the relative movement of the photosensor and the document and the output of the photosensor.

Furthermore, in a copying machine, it is necessary to synchronize the original, the photosensitive device, and the copying medium.

Therefore, in conventional image information reading devices and copying machines, the original was sent by a synchronous motor, or the sensor was sent by a synchronous motor.

For this reason, the drive device for driving the original or copy medium has become complicated, and its power consumption has also increased.

OBJECTS OF THE INVENTION The present invention has been made with attention to the above-mentioned points, and an object thereof is to provide an image reading device and a copying machine that have a simple structure and can completely synchronize each part.

Structure of the Invention The present invention includes a main body having an optical sensor, a roller whose outer peripheral surface is exposed from the main body, and a detection device for detecting the rotation angle of the roller. By providing a terminal for outputting , the relative movement of the original and the optical sensor and the output of the optical sensor can be synchronized with a simple structure.

The present invention also provides a main body having an optical sensor, a roller whose outer peripheral surface is exposed from the main body, a copying medium feeding device driven by rotation of this roller, a copying medium, and a copying section that provides image information to the copying medium. Since the output of the sensor is configured to be transmitted to the copying machine, when the copying machine of the present invention is moved over the original, the relative movement of the original and the optical sensor, the copying medium, and the copying unit are caused. This allows synchronization of relative movement with a simple structure.

The explanatory drawings of the embodiments show the embodiments of the present invention, and will be described in detail below.

Reference numeral 1 denotes a cabinet throat, and an aperture 3 facing the original 2 is provided on the lower surface. Image information obtained through the aperture 3 is imaged onto an optical sensor 6 by a lens group 4. . Here, the optical sensor 5 is a charge coupled device in which photosensitive elements are arranged in a row.
LED Device is written as CCD hereafter. ) etc. are suitable.

Reference numeral 6 denotes a driven roller, which is pressed against the drum 7 and has a pulley 8 attached thereto. Reference numeral 7 denotes a roller whose outer peripheral surface is exposed at the lower end of the cabinet 1. A rotary encoder 9 such as a photointerrupter is provided at one end of the roller 7 to detect the rotation angle of the roller 7.

Reference numeral 1o denotes thermal paper wound into a web, the leading end of which extends outward through an opening 11 provided at the rear surface of the cabinet 1.

Reference numeral 12 denotes a paper feed roller, and the thermal paper 1o is held between the paper feed roller 12 and a heating element 13 in which a large number of heating elements are arranged in a row. A pulley 14 is provided at one end of the paper feed roller 121 , and a driving force is transmitted to the pulley 14 from the pulley 8 via a belt 16 .

16 is a circuit device such as an integrated circuit which serves as an amplifier and a noise filter, and the output of the optical sensor 5 and the output of the rotary encoder 9 are inputted thereto. Also, circuit device 1
The output of 6 is connected to the heating element 13 and the output terminal 17. That is, the output of each photosensitive element of the optical sensor 6 is amplified by the circuit device 16 and sent to each heating element of the heating element 13 and the output terminal 17.

The present invention has the above structure, and its operation will be explained below.

First, the cabinet gutter 1 is placed on a document 2 such as a book.

Next, the cabinet 1 is held and pressed by hand so that the opening 3 passes over the portion of the document 2 that is desired to be copied, and the cabinet 1 is moved.

Then, the image information of the original 2 is imaged onto the optical sensor 6 by the lens group 4, and this image is scanned by the above movement. Therefore, the optical sensor 5 outputs image information of the original 2 as an electrical signal.

At this time, since the cabinet 1 is pressed onto the document 2 by hand, the roller 7 rotates as the cabinet 1 moves, and the rotary encoder 9 outputs data according to the amount of movement of the cabinet 1.

The pulley 8 also rotates according to the roller 7, and the pulley 14 is driven by the bell i.15, and the paper feed roller 212 is rotated. Since the thermal paper 10 is held between the paper feed roller 12 and the heating element 13, the thermal paper 10 is fed by the paper feed roller 12.

Since the heating element 13 receives the signal obtained by the optical sensor 6 via the circuit device 16, it generates heat according to the output of the optical sensor 6, and records image information on the thermal paper 10.

At the same time, the outputs of the optical sensor 5 and the rotary encoder 9 are outputted from an output terminal 17 via a circuit device 16, and this output terminal 17 is connected to a computer (not shown).
Data based on the image information of the document 2 can be sent to a modem (not shown) connected to a phone line or telephone line. When reading the image information data of the original document 2, the thermal paper 10 may or may not be inserted.

Effects of the Invention As described above, the present invention includes a main body having an optical sensor, a roller whose outer peripheral surface is exposed from the main body, and a detection device for detecting the rotation angle of the roller. Because it has a terminal that outputs
With a simple structure, the relative movement between the original and the optical sensor and the output of the optical sensor can be synchronized.

The present invention also provides a main body having an optical sensor, a roller whose outer circumferential surface is exposed from the main body, a copy medium feeding device driven by rotation of the roller, a copy medium, and a copy unit that provides image information to the copy medium. Since the output of the sensor is configured to be transmitted to the copying machine, when the copying machine of the present invention is moved over the original, the relative movement of the original and the optical sensor, the copying medium, and the copying unit are caused. It is possible to synchronize relative movement with a simple structure.
