Description

[Detailed Description of the Invention] The present invention provides a computer printer with a removable cassette that contains cut sheets of paper,
This is a device for a printer paper feed mechanism that has a cassette case attached to a computer, which enables single-sheet printing and simplifies the paper feed mechanism with rubber rollers and solenoids.

Furthermore, the present application provides a computer that is characterized by applying a detachable cassette case to a computer printer, thereby making it possible to print continuously on slip forms, and by simplifying the paper feeding mechanism. This relates to the paper feeding mechanism of a printer equipped with a cassette case.

Traditionally, cassette cases have been used in copying machines, but with the advent of computers with document creation functions, there will be a strong demand for cut paper rather than continuous paper.

For this reason, the present application uses a cassette case for the printer.

To explain one embodiment of the present invention, a storage section 5 for storing a cassette case 4 is formed at the rear of a main roller 3 which is rotatably attached to the frame 2 by a rotating shaft 6 in a part of the frame of the printer main body 1. An arm 7 is rotatably attached to both ends of the rotation shaft 6 of the main roller 3, and a feed roller 8 is pivotally attached to the upper end of the arm 7 by a rotation shaft 9. Attach the pulley 1
Wind the belt 12 around 0, 11 and the main roller 1
3 and the feed roller 8 are made to have the same circumferential speed, one end of the actuating arm 13 is attached to the arm 7, and the other end of the actuating arm 13 is connected to a solenoid 14 provided on a part of the frame 2. It is something.

15 is a printing head, and 16 is a sub-roller which rotates in contact with the main roller 3. 17 is a separate roller that rotates in contact with the main roller 3.

Reference numeral 18 denotes a guide provided at the rear of the separate roller 17 for feeding the cut sheet 19 forward.

In the present application, the arm 13 is pulled (suctioned) in the direction of the solenoid 14 by operating the solenoid 14 with the above-mentioned configuration, and therefore the arm 7 is sent and the roller 8 is moved in the direction of the cut sheet 19 (in the direction of the cassette case 4). When the tension feed roller 8 is brought into contact with the cut sheet 19, the cut sheets (paper) are fed into the printer 1 one by one by the rotation of the feed roller 8. Thereafter, it is fed into the main roller 3 and the sub roller 16, held there, and sent along the main roller guide 20 in the direction of the printing head 15. Thereafter, the suction of the solenoid 14 is released, the arm 7 returns to its original position, and the feed roller 8 is separated from the cut sheet 19 and remains in this state until the next operation. Then, the ticket 19 is fed into the printer 1, passes between the main roller 3 and the sub roller 16, and is sent up to the position of the print head 15, where printing begins. After printing is completed, the cut 19 (paper) is sent out in the direction of arrow X by rotating the separate roller 17 and changing the exit direction by the guide 18.

After the ticket is separated from the separate roller 17,
In order to feed the second sheet 19, the solenoid 14 is suctioned and the same process as described above is repeated to print as many sheets as desired.

As stated above, the present application relates to the frame 2 of the printer body 1.
A cassette case 4 is attached to the rear of the main roller 3, which is rotatably attached to the frame 2 by a rotating shaft 6.
A storage section 5 is formed to store the main roller 3.
An arm 7 is rotatably attached to both ends of a rotating shaft 6, and a feeding roller 8 is attached to the upper end of the arm 7.
are pivotally mounted on a rotating shaft 9, pulleys 10 and 11 are attached to the rotating shaft 6 and the rotating shaft 9, and the pulleys 10 and 11 are
The belt 12 is wound to make the main roller 3 and the feed roller 8 have the same circumferential speed, and one end of the actuating arm 13 is attached to the arm 7,
A solenoid 14 provided on a part of the frame body 2 is connected to the other end of the operating arm 13, so that continuous printing of slip sheets can be made possible by applying a removable cassette case to a computer printer. and,
The paper feeding mechanism is simple, the structure is simple, it can be used for a long time, and it is suitable for mass production.
