[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) This invention relates to a relatively small-sized copying machine that reads an image of a document with a reading head and transfers the image onto recording paper via a recording head. Take a moment.

(Prior Art) A conventional copying machine of this type has an original glass on the top surface of a flat main body, an original is set on the original glass, and in this state, the original is read from below the original glass using a reading head. The image is scanned and read, and based on this reading, the image is transferred to recording paper via a recording head.

(Problems to be Solved by the Invention) In this way, the conventional copying machine has a structure in which the document glass is provided on the top surface of the flat body, which increases the flat area of the body, making it difficult to install the copying machine. A large space had to be secured for the helmet, making it inconvenient to store and carry. This invention aims to solve these problems.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention has a vertical main body formed with a groove, and a horizontal groove at the lower end of the front surface of the main body. A document glass that can be rotated from the state to an upright position along the front of the main body is attached, and a reading head is slidably provided on the top surface of the document glass, so that it can be read when the document glass is raised up in front of the main body. An opening is formed to accommodate the head, and the original glass is placed horizontally on top of the original, and in this state, the reading head is moved to read the image on the original.

(Function) By arranging the document glass from a horizontal state to an upright state along the front surface of the main body, the planar area of the entire copy form is reduced and becomes compact.

A paper discharge port 17 is formed on the back surface of the main body 1, and a paper discharge guide 18 is provided between the paper discharge port 17 and the platen 4.

An opening 20 is formed in the lower part of the front surface of the main body 1, and a document glass 21 is attached to the lower end of the main body 1. This document glass 21 has an area larger than, for example, an A4 size document, and hinges 22 are attached to both side edges of the document glass 21, and a bottle 23 provided on the hinge 22 is attached to the opening 20.
The original glass 21 is rotated upward from the horizontal position using the bin 23 as a fulcrum, and is rotated along the front surface of the main body 1. It is designed to be able to stand upright.

Furthermore, by moving the bin 23 along the support hole 24 while the original glass 21 is placed horizontally, the original glass 21 can be displaced up and down while maintaining the horizontal position. .

A reading head 26 is provided on the upper surface of the original glass 21 . This reading head 26 has flange pieces 27 on both sides as shown in FIG.
The reading head 26 is fitted into the inside of a guide frame 28 provided on both side edges of the original glass 21, thereby allowing the reading head 26 to slide along the longitudinal direction of the original glass 21. A reel 30 is rotatably provided inside the main body 1, and this reel 3
A feed roller 531 and a pinch roller 32 rollingly connected to the outer periphery of the feed roller 31 are provided near the feed roller 31 .

A steel strip 33 is wound around the outer circumference of the reel 30 , and the strip 33 is pulled out from the reel 30 through between a feed roller 31 and a pinch roller 32 , and the pulled-out end is connected to the reading head 26 . has been done. This strip 3
3 has a cross section curved into an arc shape as shown in Figure 4, and when a certain pressure is applied along its length, it bends elastically, but normally it does not buckle. It maintains a straight state and can transmit force along its longitudinal direction.

A spiral spring 34 is incorporated inside the reel 30, and the spiral spring 34 elastically biases the reel 30 in the winding direction in which the strip 33 is wound. Further, the feed roller 31 is provided with a pulley 35, and a belt 36 is stretched between the pulley 35 and the pulley 6 of the motor 2.

On the upper surface of the lath 21 is a handle 3 for rotating the document.

9 are attached to the upper surface of the main body 1, and a plate spring-shaped latching piece 40 for removably latching the handle 38 on the upper surface of the main body 1.
is provided.

Next, we will discuss the effect.

When using a copying machine, as shown in Figures 1 and 2,
The original glass 21 is placed in a horizontal state, and in this state, the original glass 21 is folded onto the original a. At this time, manuscript a
When the original glass 21 is placed in a shop or the like having a certain thickness, the original glass 21 is displaced upward by the thickness, thereby making it possible to set the original glass 21 on the original document a.

After setting the document glass 21 on top of the document a in this manner, when a cut sheet of recording paper is inserted into the paper feed port 15, its operation is detected by a detection mechanism (not shown) and the motor 2
is started, the power of this motor 2 is transmitted to the feed roller 31 via the belt 36, this feed roller 31 rotates clockwise, the strip 33 is sequentially pushed out in the direction of the arrow, and the reading head 26 reads the document. It moves along the longitudinal direction on the surface of the lath 21, and during this time, the images of the document a are sequentially read.
The signal is sent to the recording head 3. On the other hand, the platen 4 rotates in response to the activation of the motor 2, and the recording sheet is taken in between the platen 4 and the ink ribbon 11, and the ink ribbon 11 runs together with the recording sheet. The image of the document a is sequentially transferred to the recording M1b via the ink ribbon 11 by the transfer unit 5 of the recording head 3, and after the entire image has been transferred, the recording sheet is discharged from the paper discharge port 15. . Thereafter, the motor 2 is reversely rotated, the feed row 531 is rotated counterclockwise, and the strip 33 is taken off in the opposite direction of the arrow. Along with this, the strip 33 is wound around the 2-wheel 30 due to the biasing force of the mainspring spring 34,
Further, the reading head 26 is pulled back to one end side of the original glass 21. Note that when the motor 2 rotates in reverse, the power is not transmitted to the platen 4 due to a clutch mechanism (not shown).

In this way, the copying process on the recording paper sheet is completed.
When carrying or storing the copy machine after this,
Pinch the handle 38 with your finger and place the original glass 21 into the bin 23.
Rotate upward using the fulcrum.

By this operation, the reading head 26 is housed in the opening 20, the original glass 21 stands up almost vertically along the front surface of the main body 1, and the handle 38 is moved to the latch piece 40 provided on the top surface of the main body 1. By this engagement, the original glass 21 is maintained in an upright state.

In this way, the original glass 21 will align with the front of the main body 1.]
By standing upright, the overall planar area of the copying machine is reduced, and therefore the copying machine can be stored in a narrow space and can be conveniently carried.

[Effects of the Invention] As explained above, according to the present invention, when the copying machine is not in use, the original glass is raised up to reduce the overall planar area of the copying machine, and the copying machine can be conveniently stored in a narrow space. It also has the effect of being portable.
