Abstract

PURPOSE:To allow the easy writing of the information of original paper without spending labor and time by consisting the printer of left and right take-up shafts, a thermosensitive type transparent roll film, an original paper feed roller, a reading device, and a writing device. CONSTITUTION:The original paper feed roller 5 rotates in an arrow direction in synchronization with the left take-up shaft 2 when the left and right take-up shafts 2, 3 are driven in an arrow direction and the thermosensitive type transparent roll film 4 is taken up in the arrow direction. A line sensor 8 successively reads the information of the original paper 6 when the original paper 6 is fed in this state into the spacing between the original paper feed roller 5 and a press roller 7. A thermal printer 9, then, writes this information successively onto the successively taken up thermosensitive type transparent roll film 4. The information of the original paper is easily written in this way without spending the labor and time while the thermosensitive type transparent roll film is held wound around the take-up shaft.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a roll film printer device for an overhead projector.

(Prior Art) A roll film original used in an overhead projector is wound around a left take-up shaft placed on the left side of a stage glass (original table) and pulled out onto the stage glass, and its terminal portion is It is wound around the right winding shaft located on the right side of the stage crow.

Therefore, if you now turn the handle of the right take-up shaft to the right and wind up the roll film original that is wrapped around the left take-up shaft, the roll film original will move over the stage glass from left to right. Sent. Also, if you turn the handle on the left take-up shaft to the left and rewind the roll film document that was wound onto the right take-up shaft, the roll film document will be sent over the stage glass from you to the left. .

[Problem to be solved by the invention]

However, conventional roll film originals are created by writing information such as letters and figures on a light-transmissive roll film by hand or printing, and then the roll film is wound around a winding shaft and then unwound. If you do not remove it from the shaft),
There was a problem in that it was not possible to write information, and writing the information itself took time and effort.

This invention was made to solve these conventional problems, and it is possible to easily read the information on the original paper without spending much time and effort by using a heat-sensitive transparent roll film wrapped around the take-up shaft. An object of the present invention is to provide a printer device for a roll film for an overhead projector that is capable of writing on a roll film.

[Means to solve the problem]

The roll film printer device for an overhead projector provided by the present invention consists of left and right winding shafts arranged on the left and right sides of a stage glass, a heat-sensitive transparent roll film wound around both shafts, and a rotation of the winding shaft. a yX'M4 paper feed roller that rotates by being transmitted with the y It depends on this.

[Operation] In this invention, when the reading device or the document paper feed roller reads the information on the document paper that is being fed, the writing device writes this information onto the heat-sensitive transparent roll film that is being wound up.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 schematically shows the configuration of a printer device according to an embodiment. In the figure, 1 is the stage glass (original table) of the overhead projector, 2 is the left take-up shaft placed on the left side of the stage glass 1, 3 is the right take-up shaft also placed on the right side, 4 is the left, The heat-sensitive transparent roll film wound around the right winding shaft 2.3 is fed to the left or right over the stage glass 1 by the left or right winding shaft 2 or 3.

5 is a ff1M paper feed roller. This roller 5 is configured to rotate in the opposite direction (in the direction of the arrow) in synchronization with the rotation of the left winding shaft 2 in the direction of the arrow. Reference numeral 6 denotes a document sheet, and 7 a presser roller that presses the document sheet 6 against the document paper feed roller 5. When the original paper 6 is inserted between both rollers 5.7, it is fed in the direction of the arrow.

8 is a line sensor that reads information on the original paper 6 sent by both rollers 5 and 7, and 9 is a thermal printer that writes the information read by the line sensor 8 onto a heat-sensitive transparent roll film. 10 is a tray.

FIG. 2 is a block diagram showing the connection relationships among the line sensor 8 and its reading section 10, the thermal printer 9 and its driving section 11, and the power supply 12 thereof.

Next, the operation based on the above configuration will be explained.

Now, when the left and right winding shafts 2.3 are driven in the direction of the arrow to wind up the thermal transparent roll film 4 in the direction of the arrow, the original paper feed roller 5 rotates in the direction of the arrow in synchronization with the left winding shaft 2. .

In this state, when the original paper 6 is fed between the original paper feed roller 5 and the presser roller rough, the line sensor 8 reads information on the original paper 6. Then, the thermal printer 9 writes this information onto the heat-sensitive transparent roll film 4 that is being wound up one after another.

As mentioned above, according to this embodiment, while the heat-sensitive transparent roll film 4 is still wound around the winding shaft 2.3,
Necessary information about the manuscript paper 6 can be written on the same film 4. Also, the writing is also done by line sensor 8.
This is possible by applying the facsimile principle of writing what is read with the thermal printer 9.

(Effects of the Invention) As explained above, according to the present invention, information can be easily written on a manuscript paper while the heat-sensitive transparent roll film is wound around the take-up shaft without taking much time and effort. You can get the effect that you can.
