Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to the structure of a printer having a paper feeding mechanism.

[Prior Art] The state at the time of paper setting in a conventional printer structure is described as a fourth
FIG. 5 and FIG. Many conventional printers also have an automatic paper cutting device (hereinafter referred to as an auto cutter) 12 formed to be movable above the printer body 11. However, no printer has a structure in which a hand-cut cutter is formed between the auto cutter 12 and the printer main body 11.

[Problem to be Solved by the Invention] Therefore, in the conventional configuration in which the auto cutter 12 is simply formed so as to be movable above the printer main body 11, when the ribbon cassette is exchanged or the paper 17 is exchanged, In order to set the paper 17 in a state where the auto cutter can be used, insert the paper 17 into the printer body 11 with the auto cutter 12 moved (shown in FIG. 4) and pass the cutting opening 12a of the auto cutter 12 The water 17 is drawn out longer than the paper outlet 11b so that there is no trouble, and the auto cutter 12 is returned to the operating position (shown in FIG. 5) after passing through the cutting opening 12a of the auto cutter 12 and then the auto cutter 12 and the printer. In order to remove the slack of the paper 17 between the main bodies 11, the paper 17 was pulled out from the upper portion of the cutting opening 12a of the auto cutter 12, and the auto cutter 12 had to be operated to cut the paper 17, which was very troublesome and inconvenient. . Also, use a plurality of sheets, such as copy paper, and use at least one of them.
In the case of auto cutting while leaving sheets, only the paper to be auto cut must be set as described above,
The set was more complicated than before. Due to these inconveniences, the direction of movement of the auto cutter is perpendicular to the paper path, which is more inconvenient to use such as twisting the paper, that is, the horizontal direction is small and tends to be limited to the same direction as the paper path direction. Was a hindrance to taking.

Therefore, the present invention is intended to solve the above-described problem, and the purpose is to form a hand-cutting cutter between the printer main body and the auto-cutter, and to pass the paper through a cutting opening of the auto-cutter. It is an object of the present invention to provide a printer which can set a simple sheet without needing to correct the slack of the sheet and does not limit the moving direction of the auto cutter.

[Means for Solving the Problems] To solve the above problems, the printer of the present invention is provided with a contact surface capable of contacting the paper moved by the paper feeding means, and is disposed at a paper outlet of the printer body, A hand-cutting cutter capable of manually cutting paper, a paper guide arranged opposite a contact surface so as to form a paper path of the paper, and a position downstream of the hand-cutting cutter and near the hand-cutting cutter. An automatic cutter provided with a cutting opening through which a sheet passes substantially along the paper path when in the operating position. And

Further, the printer is provided with a winding device for winding the printed sheet, and the hand-cutting cutter is arranged on the opposite side of the paper path from the winding device.

EXAMPLES Hereinafter, the present invention will be described in detail based on examples.

FIG. 1 is an assembled view of a printer having an automatic cutter and a hand-cut cutter in an operation position according to an embodiment of the present invention, and FIG. 2 is a partially enlarged view of FIG. FIG. 1,
In FIG. 2, a paper insertion slot 1a and a paper exit are provided in the printer body 1.
1b is provided. Auto cutter 2 having cutting opening 2a
Is attached to the cover 3 by screws 4 and the printer body 1
Is configured at the top. The cover 3 rotates about the fulcrum 3a as shown by the arrow A, and the auto cutter 2 also moves. The hand-cutting cutter 5 is welded to the printer main body 1 with an abutting surface that carries a part of a paper path 6 from the paper outlet 1b to the cutting opening 2a. Reference numeral 7 denotes paper (w-roll paper) composed of original paper 7a and copy paper 7b, reference numeral 8 denotes a supply and take-up device for the paper 7, reference numeral 9 denotes a paper guide forming a paper path, and reference numeral 10 denotes a ribbon cassette. Reference numeral 18 denotes a paper feed roller that is a paper feed unit that conveys the paper 7 in the paper outlet 1b direction. FIG. 3 is a view in which the paper 7 is set with the cover 3 opened and the auto cutter 2 moved.

Here, based on the above configuration, a description will be given along a use state with reference to FIGS. 1, 2, and 3. FIG. In FIG. 3, the paper 7 is fed from the supply winding device 8 into the printer main body 1 through the paper insertion opening 1a, through a printing section (not shown), the paper outlet 1b, and the paper path 6.
Through the outside.

At this time, the copy paper 7a needs to be long enough to be wound around the supply take-up device 8 and set, and the original paper 7a passing through the auto cutter 2 is also fed at the same time as the original paper 7a. Cut using the cutting cutter 5. Next, the cover 3 to which the auto cutter 2 is attached is rotated, and is placed at the operating position shown in FIGS. This completes the setting of the printing paper, and since the hand-cutting cutter 5 is formed along the paper path 6, even if the printing or the paper feeding operation is performed from this state, there is no problem such as paper jam at all and the printing is smoothly performed. The original paper 7a is discharged through the cutting opening 2a, and the copy paper 7b is wound up by the supply winding device 8.

In the case where the winding is unnecessary, that is, even when the sheet 7 is a single sheet, the sheet 7 is set in the same manner as the original paper 7a.
Is cut out from the upper part of the hand-cutting cutter 5 and cut using the hand-cutting cutter 5. Next, the cover 3 to which the auto cutter 2 is attached is rotated, and is placed at the operating position shown in FIGS. This completes the setting of the printing paper. As described above, there is no problem even if printing or paper feeding operation is performed from this state, and the paper 7 is discharged through the cutting opening 2a.

[Effects of the Invention] As described above, according to the present invention, when the auto cutter is in the operating position, the auto cutter is provided with a cutout through which the paper passes over substantially the extension of the paper path. To repair paper jams or paper jams, cut the paper ejected from the paper exit with a hand cutter, and move the auto cutter from the open position to the operating position. When the paper is conveyed, the paper passes through the cutting opening. In this way, there is no need to insert paper into the cutting slot and set it as in the past, eliminating the hassle of setting and handling paper, and setting up paper and maintaining jams in a short time and simple operation. It became possible to do it.

In addition, the rotation direction of the auto cutter was also required to be forward or rearward because the paper had to be inserted into the cutting slot in the past. There is no problem even if it is turned to the right, and the degree of freedom in design is increased, and it can meet the demands of end users.

Furthermore, since the hand-cutting cutter is disposed on the opposite side of the winding device with respect to the paper path from the paper outlet to the cutting opening, when the paper is formed in two or more layers, Since only the paper other than the paper to be wound can be cut, the processing in the event of paper jam of the layered paper can be shortened, and the practical effect of the present invention is extremely large.
