Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention relates to a small-sized copying machine that copies an image of a document onto a predetermined sheet of paper.

(Prior Art) Generally, a copying machine is provided with a document table on the top surface of the main body, and a scanner is disposed on the bottom surface of the document table so as to be movable along the longitudinal direction of the document table. Then, when the original is set on the original platen and the start switch is turned on in this state, the scanner moves sequentially in the longitudinal direction of the original platen within the main body, and this moving scanner optically scans the original. The image of the document is scanned, the information is output as an electrical signal, and the image of the document is written on paper based on this output, and copies are made.

(Problems to be solved by the invention) Copying machines are desired to be small and convenient to carry and store; however, as mentioned above,
Conventionally, the scanner moves inside the main body, so space must be secured inside the main body for the movement of the scanner.
As a result, the main body became large, making it inconvenient to carry and store. This invention is aimed at solving these problems.

(Means for Solving the Problems) In order to solve the above-mentioned problems, this invention has a flat box-shaped main body with an opening on the top surface, and is arranged opposite to the opening of this main body. and a document table that can be moved upwardly of the opening thereof;
A lifting mechanism is provided for raising and lowering the document table above the opening of the main body, and the lifting mechanism has an upper end rotatably pivoted to the document table between the document table and the main body. A plurality of levers are provided, the lower ends of which are rotatably connected to the main body, and these levers are rotated about the pivoted portions of the lower ends to move the document table into the opening of the main body. A rail is attached to the lower surface of the document table along the longitudinal direction of the document table, and a scanning device for optically reading the original set on the document table is attached to this rail. The scanner is slidably attached to the main body, and the scanner is positioned inside the main body with the document table disposed in the opening on the top surface of the main body, and at least a paper roller and the paper are located inside the main body. A copying device is provided that includes a platen that supports the paper fed out from the roller, and a thermal head that writes and copies an image of the original on the paper based on the output signal from the scanner, and By raising the document table upward from the top surface of the main body, the scanner can be pulled up from inside the main body and moved along the rail.

(Function) When the copying machine is not in use, the document table is placed in the opening of the main body, and the scanner installed on the underside of the document table is located inside the main body, making the entire copying machine compact. kept small. When the copying machine is in use from this state, the document table is raised and positioned above the top surface of the main body by the lifting mechanism.
Accordingly, the scanner on the lower surface side of the document table is pulled out from within the main body, and the area around the scanner is opened, thereby allowing the scanner to move along the rail. By moving this scanner, the image of the document set on the document table is optically read, and the thermal head operates based on the output signal to print the image of the document onto the paper fed out from the paper roller. Copied.

(Example) An example of this invention will be described below with reference to the drawings.

In the figure, 1 is a main body configured in a flat box shape with an open top surface, and inside this main body 1 is a battery 2,
Copying equipment such as a circuit board 3, a motor 4, a paper roller 5, a platen 6, and a thermal head 7 are incorporated. As shown in FIG. 2, a document table 8 is provided horizontally on the upper surface of the main body 1 to cover the upper surface. The document table 8 has a glass plate 10 mounted inside a frame 9, and the top surface of the glass plate 10 is covered with a document cover 11 that can be opened and closed. When the copying machine is used, the original cover 11 is opened, the original is placed on the glass plate 10, and the original is set, and the original cover 11 is closed to cover the original.

Side plates 15 are provided on the inside of both sides of the document table 8.
is attached, and the lower end side of this side plate 15 faces the inside of the main body 1. A lever 16 is provided between the lower end of the side plate 15 and the side wall of the main body 1 as a lifting mechanism.
16 are arranged, one end of these levers 16, 16 is rotatably attached to the side plate 15, and the other end is rotatably attached to the side wall of the main body 1 via pins 17, respectively. A document table 8 is connected to the main body 1. Further, support legs 18, 18 are provided protruding from approximately four corners of the inner surface of the document table 8, and step portions 19, 19 are formed at the lower ends of these support legs 18, 18. Engagement receiving portions 20, 20 are integrally formed on the upper side wall of the main body 1 in correspondence with these step portions 19, 19. Rails 23 are installed along the longitudinal direction on both sides of the inside of the document table 8, and a scanner 24 is slidably supported via these rails 23. This scanner 24 is moved along the rail 23 by a drive mechanism (not shown), and in accordance with this movement, optically scans the original set on the original platen 8 and reads the image of the original. For example, a lamp 25 that illuminates the original
and a photoelectric converter 26 that receives reflected light from the original and outputs the image information as an electrical signal.
and an optical system 27 that guides reflected light from the original to a photoelectric converter 26. Based on the output signal of the photoelectric converter 26, an image of the original is written onto the paper fed out from the paper roll 5 onto the platen 6 via the thermal head 7, and the original is copied. . Next, we will discuss the effect.

FIG. 2 shows the copying machine in an unused state. When using the copying machine from this state, the document table 8 is pulled upward by hand. Along with this operation, the levers 16, 16 rotate counterclockwise as shown in FIG. 19, 19 is main body 1
It engages with the engagement receiving parts 20, 20 of. As a result, the document table 8 is stably supported in a state separated from the upper surface of the main body 1, and a space s is secured below the document table 8. Then, in response to turning on the start switch, the scanner 24 moves back and forth within the space s, and the original is copied.

Furthermore, when the document table 8 is slightly shifted to the right from the usage state shown in FIG.
As shown in FIG. 2, the document table 8 descends diagonally while maintaining its horizontal state and collides with the top surface of the main body 1, and the scanner 24 is housed inside the main body 1.

In this way, the scanner 24 fits inside the main body 1 only when the copying machine is not in use, and therefore there is no need to provide a space for moving the scanner 24 inside the main body 1. The copying machine can be configured to be flat and compact, thereby making the entire copying machine more compact.

[Effects of the invention] As explained above, according to this invention, a document table is provided on the top surface of the main body so as to be movable up and down via a lifting mechanism, and the document table can be moved under the document table along the longitudinal direction of the document table. Since a scanner is installed and the document table is raised from the top surface of the main body when the copying machine is used to secure space for moving the scanner, it is necessary to provide a space within the main body for moving the scanner. Therefore, by making the main body small and flat, the entire copying machine can be made compact, and it is possible to conveniently carry and store the copying machine.
