Abstract

(57) [Abstract] [Purpose] In a printer device that has a cutter for hand cutting such as a saw blade and uses roll-shaped recording paper, even if it is pulled to either the front side or the back side of the recording paper of the discharge port. , Provides a mechanism for cutting recording paper. [Structure] The cutter blade 1 is provided on both sides of a discharge port of the recording paper 6 between the covers 2 and 2'in a direction perpendicular to the recording paper discharge direction.
And 1 '.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a printer device, and more particularly to a cutter mechanism of the printer device.

[0002]

[Prior Art]

 The cutter blade of the conventional printer device is formed on either the recording paper front side of the recording paper discharge port or the recording paper rear side of the recording paper discharge port.

[0003]

[Problems to be solved by the device]

 In the conventional printer device, the cutter blade is configured only on either the front side or the back side of the recording paper of the recording paper discharge port. For this reason, there has been a problem that the direction in which the recording paper is pulled and cut by the device is limited to only one direction. In particular, there is a problem in that left-handed people find it difficult to cut a device in which the recording paper is ejected in the left-right direction with respect to the user and the cutter blade is configured on the right side of the recording paper ejection port.

The present invention has been made in view of the above conventional circumstances, and therefore, an object of the present invention is to provide a novel printer device capable of solving the above problems inherent in the conventional technology. Especially.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the printer device according to the present invention is provided with cutter blades on both sides of a discharge port, which faces the front side and the back side of the recording paper in the discharging direction of the recording paper.

[0006]

【Example】

 Next, the present invention will be described in detail with reference to the drawings for each of its preferred embodiments.

FIG. 1 is a sectional view of a printer ejecting portion showing a first embodiment according to the present invention.

Referring to FIG. 1, the recording paper 6 sandwiched between the roller 3 and the thermal head 4 is regulated in direction by a paper guide 5, and passes through a discharge port between the cover 2 and the cover 2 ′. Guided to the outside of the device. The recording paper 6 is cut by pulling it in the direction of arrow A by the cutter blade 1 and cut by pulling it in the direction of arrow B by the cutter blade 1 '. The shape of the cutter blade at this time is shown in FIG.

FIG. 3 is a perspective view of a cutter blade shape showing a second embodiment (a modified example of the cutter blade) according to the present invention.

Referring to FIG. 3, in the second embodiment, the cutting surface of the recording paper can be made flat from a saw blade shape by making the cutter blade shape into a wedge-shaped flat shape. The other structure is the same as that of the first embodiment.

FIG. 2 is a sectional view of a printer ejecting portion showing a third embodiment of the present invention.

Referring to FIG. 2, in the third embodiment, by using the roller 3 and the roller 3 ′ for sandwiching the recording paper 6, the distance from the thermal head to the cutter blade position of the recording paper discharge port is separated. However, the cutter blade can be configured. The other structure is the same as that of the first embodiment.

In a fourth embodiment (a modification of the cutter blade) according to the present invention, the cutting surface of the recording paper is flattened by forming the cutter blade into a wedge-shaped flat shape in the third embodiment. Can be The other structure is the same as that of the third embodiment.

[0014]

[Effect of the device]

 As described above, according to the present invention, since the cutter blades are provided on both sides of the recording paper discharge port of the printer device, the recording paper is cut by pulling the recording paper in both directions of arrows A and B in FIGS. The effect that can be obtained is obtained.
