Abstract

PURPOSE:To achieve cutting of a paper with a high accuracy at a low cost with a clean cutting of the printing paper by moving a blade along the width of the paper to cut it. CONSTITUTION:A knob 15 is pressed down against the force of a spring to stick out the edge of a blade 14 and then, as the knob 15 is moved horizontally along a rail 18, the edge of the blade 14 cuts a paper 12. Upon the release of a hand from the knob 15, the blade 14 is housed into a holding body immediately, which eliminates possibility of injuring on operator's body during the cutting. Below the rail 18, namely, below the blade 14, a sheet member is buried along the entire width of a recess and brings the edge of the blade 14 into contact with the sheet member during the cutting thereby preventing damage to the edge.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing device, and an object of the present invention is to neatly cut the printing paper discharged after printing with a simple structure.

In a conventional printing device, as shown in FIG.
The edge of the printing paper 3 is tapered to form a cutting edge part 2, and the user holds and pulls the printing paper 3 that comes out from below the writing cover 1 in the direction of the arrow, and at this time, Place the paper 3 on the blade tip 2.
A configuration was adopted in which the paper was cut into sheets at the same time. This divine structure can be achieved at a low cost by simply making the edges of the paper tapered, but when cutting the paper, the cut portions often become jagged and unsightly, so it is difficult to keep them clean. It was undesirable to carry out the amputation.

Therefore, the paper is cut by driving the lunoid motor tongue and rotating a blade whose width is less than the width of the printing paper, but this does not seriously damage the paper cutting device. This method has the drawbacks that it is difficult to incorporate it into a printing device, the structure of the device is multi-dimensional, and the price is high.

The present invention eliminates these conventional drawbacks and enables clean paper cutting of 1J with a simple configuration.
One embodiment of the present invention will be described below with reference to FIG. 2 and subsequent drawings. In the figure, reference numeral 11 designates the main body of the printer, particularly a printing paper discharge section located at the rear thereof, and a paper cutting device 13 is installed near a recess that is one step lower from the main surface.

This paper cutting device includes a knife 14 for cutting paper, a knob 16 to which the knife is fixed, a storage holder 1 that pulls the knob 16 via a spring 16, and a box-shaped holder 17. ,
! :, This holding body 17 is held slidably in the width direction of the printing paper 12 with "-", and is comprised of rails 18 having a substantially C-shaped cross section and fixed on the apparatus main body 1 at both ends. Note that 19 is a long hole provided in the holding body 17 for protruding and operating the retractable knob 16;
2Q and 21 are shafts and engagement plates for holding the holding body 17 in the groove 1B& of the rail 18.

Next, the cutting operation in the above embodiment will be explained.

Since the knife 14 is normally completely retracted into the holder 17 by the force of the spring 16, the user will not be injured by the cutting edge of the knife 14.

When cutting, the knob 16 is pushed down against the force of the spring 16 to cause the cutting edge of the blade 14 to protrude outside the holder 17, and when the knob 15 is moved horizontally along the rail 18 in this state, the blade 14 is The cutting edge cuts the paper 12. knob 16
As soon as the cutter 14 is released, it is immediately stored in the holder 17, so there is no need to worry about injury during cutting. 1. - The seat part 4) J22 is embedded under the rail 18, more specifically, below the blade 14, over the entire width of the recess 11a, so that the cutting edge of the blade 14 will touch the sheet member 2 when cutting.
2 to prevent damage to the cutting edge. The sheet member 22 is made of a material such as vinyl chloride with a small amount of plasticizer added or butadiene rubber. This sheet member 22 can also be replaced by making the device main body 1 itself from such a material.

If the trench knife 14 is made to always protrude outside, the spring 16 is unnecessary and the knob 16 and the holder 17 can be integrated.

As explained above, according to the printing device of the present invention, it is possible to easily print by using at least three parts: a knife for cutting paper, a holding member thereof, and a holding member that holds these so as to be slidable in the width direction of the printing paper. It can be configured as a paper cutting device, and since this paper cutting device cuts the paper by moving a blade in the width direction of the printing paper, the printing paper can be cut cleanly, and the overall cost is reduced. It is possible to perform high-quality paper cutting.
