Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a printing device in which a printing paper cutter body for cutting printing paper is formed to be detachably attached to the main body of the device.

Conventionally, this type of printing device has been proposed in which a cutter body is simply slid on, or in which the printer is attached and removed from the back of the device cover.

However, with the former configuration, there is wobbling during use and it is not possible to cut cleanly.

Furthermore, there is the inconvenience that the cutter body may come off while being carried.

Furthermore, in the latter configuration, the cover of the device must be removed each time the cutter body is installed or removed, which is very inconvenient.

The present invention was developed in view of these conventional drawbacks, and the object is to provide a printing device in which the cutter body is easy to install and remove, and there is no wobbling when installed, and the printer does not easily come off. .

Hereinafter, one embodiment of the present invention will be described in detail using the drawings.

FIG. 1 is a perspective view of the device with a printing paper cutter attached to it, FIG. 2 is a side sectional view taken along the line A-A' shown in FIG. 1, and FIG. 3 is an exploded view of FIG. 2.

In the figure, 1 is a printing paper cutter, 2 is a printing paper cutter attachment part, 3 is a knurling part that is integrated with the printing paper cutter, 4 is a retaining claw provided on the printing paper cutter,
5 is a recess in the cutter attachment part that engages with the claw 4, 6 is a printing paper, 7 is a protrusion on the cutter for attaching the cutter to the cutter attachment part, and 8 is a slope provided on the cutter so that the cutter can be removed smoothly. 9 is a projection on the mounting portion side corresponding to the projection of the cutter, and 10 is a rib on the mounting portion side on which the cutter slides.

As shown in Figure 3 a, l), attach the cutter 1 to the mounting part 2.
To attach the cutter 1 to the mounting part 2, first place the cutter 1 on the rib 10 provided on the mounting part 2, and then slide the cutter in the direction of the horizontal arrow in the figure. The claws 4 of the cutter engage with the four parts 5 of the attachment part 5 due to the mutual elasticity of the cutter 1, and the cutter 1 is fixed to the attachment part 2 as shown in FIG.

Also, if you want to insert the cutter 1 from the mounting part 2, you can do it in the reverse order as described above.In the state shown in Fig. 2, first slide the cutter in the downward direction, and the gap between the cutter 1 and the mounting part 2 will be removed. Due to its elasticity, the claw 4 of the cutter comes off from the marking part 5 of the attachment part, and at the same time, the protrusion 7 also comes off from the protrusion 9.

When the cutter 1 is further slid, the protrusion 9 of the mounting portion hits the slope 8 provided on the cutter, and the cutter 1 can slide along the slope in the direction of the diagonal arrow in FIG.

Here, the printing paper cutter is attached near the installation parts such as the printing body and the printing drive unit, but it may also be attached to the printer cover or the like.

As explained above, according to the configuration of the present invention, it is very easy to install and remove the print paper cutter, and furthermore, it has excellent effects such as no looseness during installation and no possibility of it coming off while being carried. .

[Brief explanation of the drawing]

Claims (1)

[Scope of Claim for Utility Model Registration] In a printing device comprising a printing paper cutter main body for cutting a printed part that is detachably attached to the device main body, a cutter main body formed in a U-shape in cross section. 1, an elastic engagement claw portion 4 formed protrudingly from one end of the main body 1, and the main body 1.
An L-shaped protrusion 7 is formed by cutting into the leg part, an inclined part 8 is formed between the protrusion and the engaging claw part 4, and a through hole for taking out printed paper is bored in the center part. In addition, a cutter mounting part 2 has four parts having sliding ribs 10 for supporting the legs of the cutter main body 1 on both sides; a recessed portion 5 that elastically engages and disengages from the engaging claw portion 4 of the main body;
A printing device characterized by comprising a protrusion 9 formed on the sliding rib 10 so as to engage with the protrusion 7 or contact the inclined portion 8 depending on the sliding direction of the cutter main body 1.
