Abstract

PURPOSE:To automatically cut a feed hole portion off a continuous form paper after printing and eliminate the need for a manual cutting process by providing a cutting blade in a paper pressing mechanism for pressing the paper to prevent the paper from being disengaged from a paper feeding mechanism of a printer. CONSTITUTION:A main body 1 of a printer incorporates a paper feeding mechanism 2, and is equipped with a paper pressing mechanism 3. The paper pressing mechanism comprises a belt-shaped body provided with protrusions to be engaged with feed holes of a continuous form paper 4. A cutting blade 5 is foldably mounted at a position coinciding with a perforation of the paper 4 when the paper pressing mechanism 3 is turned back to the side of the paper feeding mechanism 2. Therefore, simultaneously with the automatic feeding of the continuous form paper, the paper part including the feed holes is cut off along the perforation. A cutout 6 is provided for preventing the cutting blade 5 from abutting against the main body 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing device, and more particularly to a printing device having a function of separating paper feed holes of continuous paper.

[Conventional technology]

Conventional printing devices that use continuous paper have a wheel-like or belt-like paper feed mechanism that has protrusions that engage with paper feed holes in the printing paper, and a paper holder that presses the continuous paper against it and prevents it from shifting or lifting. The paper holding mechanism is a mechanism that can be opened and closed to attach and adjust the position of continuous paper. The printed continuous paper was ejected to the outside with the paper feed hole still attached to the paper feed mechanism.

[Problem that the invention seeks to solve]

As described above, conventional printing devices eject the printed continuous paper as is, so if it was necessary to remove the paper feed hole, the perforations had to be manually cut off after printing was completed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a printing device that has a function of automatically cutting off the paper feeding portion immediately after printing using a cutting blade provided in the paper holding mechanism of the printing device.

[Means for solving problems]

A printing device of the present invention includes a paper feed mechanism and a paper holding mechanism that can be opened and closed, and prints the contents of a storage medium such as a personal computer on continuous paper, in which the paper holding mechanism is connected to the paper feeding mechanism. It is configured to have a cutting blade at a position corresponding to the perforation of the paper feed hole portion of the continuous paper fed out.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of a paper pressing mechanism according to an embodiment of the present invention. The main body 1 of the apparatus includes a paper feeding mechanism 2, and a paper presser WI3 is attached thereto. The paper feed mechanism 2 is a belt-like member having a protrusion that engages with the paper feed hole of the continuous paper 4, and the paper holding mechanism 3 can be opened and closed for attaching and replacing the continuous paper 4. FIG. 1(a) shows a state in use with the paper holding mechanism 3 closed, and FIG. 1(b) shows a state in which the paper holding mechanism 3 is opened and the continuous paper 4 is removed. When the paper holding mechanism 3 is folded back toward the paper feeding mechanism 2 side, a cutting blade 5 is foldably attached at a position that exactly matches the perforation of the continuous paper 4. Therefore, as the continuous paper is automatically fed, the portion including the paper feed hole is cut from the perforation. The cutout 6 is provided to prevent the cutting blade 5 from hitting the device body 1. Continuous paper may have perforations on either the left or right side, or both, depending on the type, but this can be accommodated by folding the cutting blade 5.

Note that the folding mechanism of the cutting blade 5 is omitted in the figure.

〔Effect of the invention〕

As explained above, the present invention provides a cutting blade in the paper holding mechanism that holds the continuous paper so that it does not come off from the paper feed mechanism of the printing device, so that the paper feed hole is automatically removed from the continuous paper after printing. This has the effect of eliminating the need for a manual cutting process.
