Description

Printer with stamp stamp

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer having a stamp stamp function, and more particularly, to a printer for driving a stamp installed inside a printer to stamp a preset stamp position on a printed document.

In line with the social trend of office automation (OA) today, office automation devices such as computers and printers have been widely distributed to computers at various levels, such as government offices. These are used.

As with all official documents, it is necessary to seal the issuing agency's official seal (or seal) so that the official document printed using the printer is also effective. In the past, it has been processed by computerization. It is not a factor that lowers the efficiency of the task in promoting rapid task processing, and is not a factor of time and human waste.

Accordingly, the present invention, in view of the conventional problems, to install a stamp stamped with a certain stamp such as seal or stamp inside the printer, and drive it when printing the official document to stamp the preset stamp position on the printed document, An object thereof is to provide a printer having a so-called stamp seal function.

The present invention for achieving the above object is a printer for printing data to be printed via a printing portion on a paper conveyed along a predetermined conveyance path by a paper conveying portion: a stamp stamped with an arbitrary seal, and the conveyance. A paper sensor for determining the stamp position of the stamp on a furnace, a stamp driver for driving the stamp and stamping the stamp at a preset stamp position on the paper, and a detection signal generated from the paper sensor And a controller for controlling the stamp driver.

Optionally, it may be configured to further include a seal position variable for changing the seal position. Here, the stamping position variable part is a vertical position variable part for changing the stamping position of the stamp in the conveying direction of the paper, and the horizontal position variable for changing the stamping position of the stamp in a direction orthogonal to the conveying direction of the paper. It is preferable to comprise with a part.

More preferably, the vertical position variable portion is configured to change the stamp position by changing the paper transfer time from the time when the detection signal is generated by the paper sensor to drive the stamp, the horizontal position variable portion, A motor for generating rotational power in accordance with a control signal generated by the controller, a timing belt converting the rotational power into linear power and transmitting the rotational power to the stamp driving unit, and linear movement of the stamp driving unit. It consists of a guiding shaft.

Here, the stamp driver may be configured as a solenoid to be driven according to the control signal generated from the controller.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Here, the present invention will be described as an embodiment of the electrophotographic developing method, and a detailed description of the electrophotographic developing method will be omitted.

Referring to FIG. 1, a transfer photo developing printer, while applying a high voltage to the charging roller 10, rotates in contact with the photosensitive member 20 to uniformly charge the surface of the photosensitive member 20 and exposes an laser scanning system. Unit; LSU (30) to scan the surface of the photosensitive member 20 to generate an electrostatic latent image (Electro-static Latent Image) and then toner (toner) in the electrostatic latent image formed on the photosensitive member 20 through the developer 40 It is developed as a visible image by supplying. Then, a transfer voltage is applied between the transfer roller 50 and the photosensitive member 20 to rotate, thereby transferring an image formed of toner to the paper 100 passing therebetween, and compressing the heating roller 60 with the heating roller 60. Passed between the rollers (Pressure Roller) 70 and the image is fixed on the paper by heat and pressure, discharged, and the image forming process of one cycle (static cycle) by eliminating the photosensitive member 20 is transferred through the antistatic lamp 80 Do this.

Through such a process, the stamp 110 and the stamp driver 120 are installed inside the printer to seal the seal or stamp on the printed paper 100.

Of course, the stamp 110 is stamped in advance, such as a predetermined seal, seal, etc., is installed on the conveyance path (P) of the paper 100 to face the printing surface of the paper 100, driving such as a solenoid The stamp is driven and stamped by the stamp drive unit 120 made of means is stamped on the paper (100).

Then, on the conveying path (P) is installed a paper sensor 130 for detecting the paper position to determine the stamping position of the stamp (110).

In addition, as shown in FIG. 2, the rotational power generated by the motor 140 is converted into linear power through the timing belt 150 to be transmitted to the stamp driver 120, and the linear movement of the stamp driver 120 is transferred to the shaft ( Guiding through the 160, it is configured to be able to change the stamping position of the stamp 110 in the horizontal direction (direction perpendicular to the conveying direction of the paper) of the paper 100.

Here, the stamping position of the stamp 110 may be changed in the vertical direction (the conveying direction of the paper) of the paper 100 without a separate device, and the stamp is detected from the time when the paper 100 is detected by the paper sensor 130. By changing the paper feed time until driving (110). After the paper 100 is detected by the paper sensor 130, the transport distance of the paper 100 is changed from D1 to D3 in proportion to the transport time of the paper 100.

The printer of the present invention having such a configuration operates in the order shown in FIG. 3.

First, when a print command is issued from a computer (not shown), the printer receives the print command along with data to be printed and prints it on the paper 100 through the printing unit 90 in an electrophotographic development method.

At this time, the control unit (not shown) of the printer checks whether the stamping function is selected by the user (S10), and if this function is not selected, performs printing in the same manner as when printing a general document (S20). ).

Here, when the stamp stamp function is selected by the user, the controller checks whether to change the stamp position of the stamp 110 (S30), and if there is no change, selects a preset standard position as the stamp position (S40). .

At this time, if there is a change, the changed position is selected as the stamp position, wherein the adjustment according to the newly selected stamp position, for example, the paper transfer time for resetting the vertical position or the stamp driver is driven by driving the motor 140. The adjustment is performed by moving the 120 to change the horizontal position (S50).

As such, when the stamping position of the stamp 110 is selected, the paper conveying unit (not shown) is controlled to transfer the paper 100 along the conveying path P to be printed through the printing unit 90 (S60, S70), At the same time, it is checked whether the printed paper 100 is detected by the paper sensor 140 (S80).

When the printed paper 100 is transferred to the paper sensor 130 and a detection signal is generated by the paper sensor 130, the controller stops the paper feed after delaying the set paper feed time (S90 and S100). .

Then, the stamp driving unit 120 is controlled to seal the stamp 110 on the printed paper 100 (S110), and then the paper 100 is transported again along the transport path P and discharged (S120). .

As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications can be made without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be defined by the following claims and their equivalents.

As described in detail above, the printer having a stamp stamp function according to the present invention, by printing the official document and stamping the seal (or seal) necessary for its effect generation, it becomes possible to collective processing using computerization While preventing time loss, it is possible to assign manpower for other tasks to increase the efficiency of the work.
