Problems solved by technology

[0008] However, in the printer described in Patent Document 1, for example, when the operator forgets to take out the cut sheets, the cut sheets may remain and accumulate at the paper outlet.
If the cut sheets are piled up, the accumulated cut sheets will interfere with the cutting edge of the movable blade to cause cutting failure, or the piled up cut sheets will be cut again to produce small cut pieces, which may adversely affect the operation of the printer.
[0009] In addition, in the printer having the continuous ledger sheet cutting device described in Patent Document 2, there is a problem that the mechanism is complicated and the size becomes large because there is a conveyance unit for the cut cut sheets.

[0060] Here, refer to figure 2 and image 3 The paper discharge device 50 will be described. image 3 It is a diagram explaining the paper discharge device 50, and in detail, it is a perspective view seen from the recording paper discharge direction. image 3 The indicated X direction, Y direction and Z direction represent the same figure 1 The indicated X direction, Y direction, and Z direction are the same directions.

[0061] Such as figure 2 As shown, the paper discharge device 50 is disposed between the paper feeding mechanism 32 and the front case 24 of the exterior case 22 . In detail, along figure 2 The paper feed mechanism 32 , the paper discharge device 50 , and the front case 24 (outer case 22 ) are arranged in order in the middle X direction, and collectively serve as the paper transport path 33 . The paper discharge device 50 includes an automatic cutter 40 and a paper stage 52 .

[0084] Here, refer to Figure 6 The paper discharge device 50 of the second embodiment will be described. Figure 6 It is a figure explaining the paper discharge apparatus 50 of 2nd Embodiment. The second embodiment is an example in which the protrusion 55 is different from that of the first embodiment. The same reference numerals are assigned to the same structures and contents as those of the first embodiment, and description thereof will be omitted.

[0085] Such as Figure 6 As shown, the paper discharge device 50 of the second embodiment includes an automatic cutter 40 and a paper loading table 52A. As in the first embodiment, the paper stage 52A has a rectangular paper guide surface along the paper conveyance path 33 with the long side in the paper width direction (Y direction) and the short side in the paper conveyance direction (X direction). 54. The paper guide surface 54 is disposed so as to become slightly lower in the Z direction from the position of the blade...

Abstract

The present invention provides a paper discharge device, a paper discharge method, and a printer. The paper discharge device has a paper feed mechanism that conveys recording paper; an automatic cutter that has a drive unit and cuts the recording paper conveyed by the paper feed mechanism into a slip by drive power from the drive unit; and a paper guide unit that has a paper guide surface that supports the slip cut by the automatic cutter and a protruding part that is disposed to the paper guide surface and supports part of the cut end of the slip at a position causing the part of the cut end to contact the recording paper conveyed by the paper feed mechanism.

Description

technical field [0001] The present invention relates to a paper discharge device, a paper discharge method, and a printer provided with the paper discharge device for recording paper on which information is recorded and cut into cut sheets. Background technique [0002] In recent years, printers with automatic cutters have been used in various fields such as goods distribution and business distribution. This type of printer prints information on long strips of recording paper, cuts the recording paper into predetermined lengths, and issues them as cut sheets. The automatic cutter is arranged in a downstream portion of the paper conveyance path that passes through the printing position and reaches the paper outlet. Then, the cut recording paper (cut sheet) is discharged from the paper outlet. Examples of automatic knives include scissor-type knives in which a movable blade rotates toward and away from a fixed blade, and knives in which a movable blade linearly reciprocates ...
