Abstract

Provided is a recording medium transport device that is applied to a printer, a scanner, or a multi-function printer and prevents paper jams.
The apparatus includes a recording medium supply path having at least a pickup roller and a supply roller for transferring a recording medium to be scanned or printed. In particular, the block member 80 is installed between the pickup roller 10 and the supply roller 20 and is slightly below the supply roller 20. Therefore, in order to pull out the recording medium 40 so as to come into contact with the block member 80, the recording roller enters the folding path that is linked to the recording medium supply path when the supply roller 20 reverses. Thereafter, the recording medium transported by the pickup roller 10 and the supply roller 20 in the recording medium supply path is further scanned or printed on two sides.

Description

  The present invention relates to a recording medium transport apparatus applied to a scanner or a printer, and more particularly to a recording medium transport apparatus capable of processing operations on both sides of a recording medium.

  Scanners and printers are now widely used by individuals and offices for scanning, printing, copying, storing and faxing documents, and play a very important role today.

Such products, such as fax machines, printers, scanners, and multifunction printers, process at least one side of a recording medium. In addition to manual processing when both sides of the recording medium need to be scanned, read and printed, several processing devices built into the machine have been developed. Related patents are disclosed in Patent Documents 1 to 5, and the like.

  Although this type of device can process both-side recording media with a scanner or printer, the device is large and maintenance is very difficult, and it is a common device that has a complicated structure and mechanism. There are drawbacks. Further, when the back surface of the recording medium is transported, too many components may immediately cause a paper jam or wrinkling of the recording medium, which causes inconvenience to the user.

  An object of the present invention is to provide a recording medium transport apparatus that has a simple structure, has few components, is small, and can prevent clogging of a recording medium during transport.

  The recording medium transfer device according to the present invention is applied to scanners and printers such as fax machines, printers, scanners, and multifunction printers that handle double-sided scanning or printing operations.

  The recording medium transport apparatus according to the present invention includes a recording medium supply path having at least a pickup roller, and a supply roller for transporting the recording medium to be scanned or printed. In particular, the block member is installed between the pickup roller and the supply roller and is just below the supply roller, so that the recording medium can be pulled out to contact the block member. When the supply roller reverses, the recording medium enters a folding path connected to the recording medium supply path. Thereafter, the back surface of the recording medium transferred by the pickup roller and the supply roller in the recording medium supply path is further scanned or printed.

  The recording medium transfer device according to the present invention has the above-described configuration, so that the structure is simple, the number of components is small, the size is small, the maintenance is easy, and the recording medium is prevented from being clogged or wrinkled.

  The present invention will be more fully understood from the following detailed description. The following description is for the purpose of giving examples, and does not limit the present invention.

  1 to 6 are views showing a series of operations of the recording medium transport device according to the present invention.

  The recording medium transfer device according to the present invention is applied to a scanner, a printer, or the like. For example, the recording medium transfer device can be applied to a scanner, a fax machine, a printer, a copier, or a multi-function printer that transfers a recording medium 40 such as paper.

  In FIG. 1 to FIG. 6 showing a series of operations of the recording medium transfer device according to the present invention, the recording medium 40 is prepared in the cartridge 50 and taken out by the pickup roller 60. At least a pickup roller 10 and a supply roller 20 are arranged in the recording medium supply path 100 of the recording medium transfer apparatus of the present invention. The rollers 10 and 20 have a rubber surface in order to improve the friction with the recording medium 40. The number and arrangement of the rollers 10 and 20 depend on functional requirements and are not limited to those shown in the drawings.

The recording medium 40 is taken up by the pickup roller 10 and sent by the supply roller 20 for further processing by the printing unit 30. For easier understanding, the front and back surfaces of the recording medium will be described below as a first surface and a second surface, respectively.
For example, as illustrated in FIG. 3, the printing unit 30 prints on the first surface of the recording medium 40. The scanning unit 90 that scans the recording medium is selectively installed in the recording medium supply path 100 through which the recording medium passes.

  The block member 80 is installed between the pickup roller 10 and the supply roller 20 and is slightly below the supply roller 20. The arrangement position of the block member 80 is not limited to this, and may be a position that depends only on the size of the supply roller 20 and does not interfere with feeding the recording medium 40 forward in the recording medium supply path 100.

As illustrated in FIG. 3, after the processing of the first surface of the recording medium 40 is finished by the recording medium pickup roller 10 and the supply roller 20, the supply roller is pulled out so as to pull out the recording medium 40 and contact the block member 80. 20 reverses and reverses. Next, the recording medium 40 is guided to a return path 200 that is linked to the recording medium supply path 100.
As shown in FIG. 4, at least the return roller 70 is in the middle of the path 200 so as to push the recording medium 40 toward the supply path 100 so that the recording medium passes smoothly through the folding path 200. , Selectively installed.

  As shown in FIG. 5, after entering the recording medium supply path 100, the recording medium 40 is transported by the pickup roller 10 along the recording medium supply path 100 toward the supply roller 20. As shown in the figure, the second surface is further printed by the printing unit 30.

  As described above, the recording medium 40 is transported by the pickup roller 10 and the supply roller 20 along the recording medium supply path 100 with respect to the first surface, scanned by the scanning unit 90, or printed by the printing unit 30. Then, it is reversed by the supply roller 20 and guided by the block member 80 so as to be along the turn-back path 200, and again transported along the recording medium supply path 100 to perform predetermined processing on the second surface whose direction has changed. Is done. This apparatus is simple in structure, has few components, is small in size, is easy to maintain, and prevents the recording medium from being jammed or wrinkled. Therefore, the recording medium transfer device of the present invention is creative and practical.

Although the present invention is as described above, it is clear that the present invention can be modified in many ways. Such modifications are not to be regarded as a departure from the spirit and scope of the present invention, and all modifications apparent to those skilled in the art are intended to be included within the scope of the claims for utility model registration of the present invention.
