Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording paper printing and discharging device for printing and discharging strip-shaped recording paper used in printer-equipped devices such as registers.

Conventional recording paper print feeding devices, as known for example in registers, have a paper feed mechanism that applies a conveying force to the feeding section in the middle of a paper guide that guides the feeding section of the band-shaped recording paper wound into a roll. In addition to providing a printing mechanism for printing on the mechanism and the feeding section, a cutter mechanism is arranged at the end of the paper guide, and a paper feeding port through which the printed feeding section is inserted is provided in the housing wall of the printer-equipped device. The cutter mechanism is formed by attaching to the base of the cutter mechanism a cutter protector having a slanted portion that guides the tip of the feeding portion and allows the paper feeding port to be inserted therethrough.

By the way, in devices with printers, there is a time lag between the completion of user processing such as keyboard operations (including change processing in the case of registers) and the completion of feeding the recording paper from the paper feeding port, so the user There are many cases where the user waits while holding onto the feeding unit that is feeding out the paper from the paper feeding port. This tendency is particularly strong in the case of registers.

However, there are various ways to grasp the feeding section that is fed out from the paper feeding port, but in the above-mentioned conventional device, for example, the feeding section may be grasped close to the paper feeding port, or the feeding section may be grasped at the slanted part of the cutter protector. If the paper feeder is held in front of the feeder in the paper feed direction, the paper feeding action is impaired, and the feeder gets stuck in the space between the cutter protector and the base of the cutter mechanism, or the paper feeder gets stuck in the space between the cutter protector and the base of the cutter mechanism. There was a problem with the screen getting stuck.

The present invention was devised based on the above circumstances, and its purpose is to print recording paper in printer-equipped equipment that can prevent paper jams from occurring even when the printed feeder is grasped from any direction. The purpose of the present invention is to provide a delivery device.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5.

Reference numeral 1 in FIG. 1 is a housing wall of a device with a printer (in this example, the case is a register), and this wall 1 includes a keyboard section 2, a money display section 3, and, for example, a removable auxiliary housing wall. 4 are provided.

A printing section 5 is housed within this housing wall 1. The printing section 5 is shown in detail in FIGS. 4 and 5. That is, the printing section 5 prints on the paper guides 6 and 7 that guide the feeding section B of the band-shaped recording paper A wound into a roll, the paper feeding mechanism 8 that applies a conveying force to the feeding section B, and the feeding section B. It is formed to include a printing mechanism 9 and a cutter mechanism 10 for cutting the feeding section B. In the case of this embodiment, the paper feeding mechanism 8 includes a rotationally driven roller 8a and a roller 8b that rolls into contact with the roller 8a, and is disposed, for example, in the middle of the paper guide 6. This paper feeding mechanism 8 is such that the feeding section B is sandwiched between rollers 8a and 8b, and the feeding section B is conveyed and passed. For example, a line printer is used as the printing mechanism 9, and in the figure, 9a is a printing stand, 9b is a paper stopper with a window, 9c is a printing hammer, and 9d is an ink supply roller that rolls into contact with the printing stand 9a. This printing mechanism 9 is arranged, for example, between the paper guides 6 and 7,
In response to a control signal based on the operation of the keyboard section 2, the printing stand 9a is rotated to select a necessary printing string, and the printing hammer 9c is struck to form a print on one side of the feeding section B. In addition,
In the figure, reference numeral 11 denotes a stamp that is unique to the register, and is used to record the store name, telephone number, characters expressing gratitude, etc. on the feeding part B. For example, it is stamped on one side 7a of the paper guide 7. Recording is performed on the feeding portion B by a stamping operation in which the stamping member is inserted through a window (not shown) provided on one side 7a. Furthermore, the cutter mechanism 10 has a fixed blade 10b attached to a cutter base 10a having a feeding portion passage hole, and
The movable blade 10c is rotatably attached via a pivot 10d, and a solenoid (not shown) is connected to the movable blade 10c. In the figure, 10e indicates a spring for pressing the movable blade 10c against the surface of the fixed blade 10b on the side opposite to the paper guide 7, and 10f indicates a cutter cover on the side of the movable blade 10c. This cutter mechanism 10 is disposed, for example, near the end of the paper guide 7, and cuts the feeding portion B to a required size.

Further, in the case wall 1, for example, the auxiliary case wall 4, a paper feed-out port 12 is opened, facing the terminal end of the paper guide 7, into which the printed feed-out portion B is inserted. One edge 12a of this outlet 12 is inclined inward as shown in FIG. Furthermore, a paper lead-out guide 13 is provided on the auxiliary housing wall 4 on the side opposite to the printing section 5, covering the paper feed-out port 12. This lead-out guide 13 is molded from synthetic resin, and has positioning protrusions 13a, 13b and engaging claws 13c disposed between them protrudingly provided on both side walls, as shown in FIG. 2, for example. The portion 13d facing the paper feed port 12 is tilted (note that the forced bending portion 1 described below
The slope is opposite to that of 5. ), and is provided with a paper outlet 14 surrounded by this portion 13d and the above-mentioned both side walls. This paper guide 13 has positioning protrusions 13a and 13b.
and the engaging claw 13c to the paper feed port 1.
2, the engaging claw 13c is engaged with the back surface of the mouth edge of the paper feed port 12, and the positioning protrusions 13a, 13b are inserted into the edge 12a and the edge 12 opposite to this edge 12a.
b, for positioning. Furthermore, since the engaging claw 13c of the paper guide 13 is inserted through the paper delivery port 12 with elastic deformation, by inserting a finger from the paper delivery port 14, engaging the portion 13d, and pulling strongly, It can be easily removed from the auxiliary housing wall 4. The paper outlet 14 is provided in a direction in which the recording paper A is bent due to its curl, as a more preferable example than in this embodiment. Further, a paper bending forcing portion 15 is provided between the paper outlet 14 of the paper guide 13 and the terminal end of the paper guide 7. This forced bending part 15 is the paper guide 7
A straight line 0- connecting the terminal end of the paper outlet 14 and the paper outlet 14
0', and is used to guide the feeding section B away from the paper outlet 14. In this embodiment, the paper bending forcing section 15 also serves as a cutter protector that covers the fixed blade 10b of the cutter mechanism 10, so the paper bending forcing section 15
At 6, it is attached to the cutter base 10a together with the fixed blade 10b.

According to one embodiment of the above configuration, the feeding section B printed by the operation of the printing section 5 is first forced to bend by the paper bending forcing section 15 so that the paper curls are emphasized more. 15 and is led out from the paper outlet 14 of the paper guide 13 to the outside of the housing wall 1. In this case, even if the distal end of the dispensing part B contacts the portion 13d of the paper dispensing guide 13 facing the paper dispensing port 12, the distal end of the dispensing section B quickly moves to the paper dispensing port due to the paper curl and the inclination of the section 13d. 14.

In this delivery state, the user grasps the part of the paper delivery unit B that comes out from the paper delivery port 14 (the gripped position is indicated by H in FIG. 4) and waits for the completion of paper delivery. Even in such cases, paper jams can be prevented for the following reasons. First, since the paper feed-out port 12 is covered by the paper lead-out guide 13, the feed-out portion B cannot be grasped from the direction along the inclined portion of the cutter protector (that is, the forced bending portion 15 in this embodiment). Second, by covering the paper delivery port 12 with the paper delivery guide 13, the delivery portion B cannot be grasped near the paper delivery port, and the delivery portion B extends from the end of the paper guide 7 to the paper delivery port 14. By ensuring a long dimension, bending of the feeding portion B within this length range can be facilitated. Thirdly, the paper bending forcing section 15 gives the paper bending forcing section 15 a tendency to forcibly bend the portion where the bending deformation has been facilitated, so that the feeding of the paper in the feeding section B is continued. That is, as a result of the synergistic effect of these reasons, the feeding section B moves and is naturally pushed out from the paper outlet 14, as schematically shown by the two-dot chain line and the arrow in FIG. 5, paper jams are prevented. In particular, in this embodiment, the paper bending forcing section forces the feeding section B in a direction that emphasizes the curling of the paper, so that the effect of preventing paper jams is greater. Therefore, it is possible to prevent a decrease in the operating rate of the register due to paper jams and to prevent the trouble of reissuing recording paper twice, which has a great practical effect.

In addition, after the necessary paper feeding of feeding section B is completed,
Of course, the feeding portion B is cut by the operation of the cutter mechanism 10, but according to this embodiment, the cut portion is prevented from scattering after cutting. In other words, the feeding section is cut off when cutting is completed.
The lower end of B ₁ rides on the movable blade 10c and is moved in the direction of the arrow in FIG.
When B ₁ falls to the rear as shown in the position A in Fig. 5, this feeding portion B ₁ is
5 and the tip 10f' of the cutter cover 10f. In addition, if the feeding part _B1 falls forward as shown in the position B in Fig. 5, this feeding part
B ₁ can be supported at least by the tip 13d' of the portion 13d and the paper bending forcing portion 15. In this case, the tip 10f' of the cutter cover 10f is also part of the feeding part B ₁
may be supported. In this way, it is possible to prevent the cut feeding portion B ₁ from scattering, thereby preventing the operator from having to frequently pick up the scattered feeding portion B ₁ during register work as in the past.

Furthermore, according to this embodiment, since the paper guide 13 is detachable, in the unlikely event that the printing section 5
If a paper jam occurs inside, the paper delivery port 12 can be opened to deal with it, and if the paper delivery guide 13 becomes dirty, it can be removed and cleaned easily.

Note that the present invention is not limited to the above embodiment. For example, as shown in FIG. 6, the paper bending forcing section 15 may be molded integrally with the paper guide 13. Further, the paper guide 13 may be molded integrally with the housing wall 1. Further, in the above embodiment, the recording paper feeding section is fed upward, but the feeding direction of the feeding section may be sideways, and even when the paper is fed sideways, the paper bending forced part 15 and the tip 13d' of the portion 13d or Paper bending forced part 15 and tip 10 of cutter cover 10f
The support provided by f′ can prevent the cut feeding portion _B1 from scattering. Furthermore, the present invention can be applied to devices with printers other than cash registers. In addition, when implementing the present invention, unless it is contrary to the gist of the invention, the printing unit, paper guide, paper feed mechanism, printing mechanism, cutter mechanism, housing wall, paper outlet, paper outlet guide, paper outlet It goes without saying that the specific structure, shape, position, etc. of the paper bending force section, etc., are not limited to the one embodiment described above, and can be configured and implemented in various ways.

As explained above, the present invention is based on a paper that has a paper output port that covers the paper feed port provided on the housing wall that houses the printing unit that feeds the band-shaped recording paper, prints it, and then cuts it. It is characterized by a configuration in which a lead-out guide is provided, and a paper bending forcing part is provided between the paper lead-out port, the paper lead-out port of the printing section, and the end of the paper guide of the printing section, which intersects diagonally with respect to the straight line connecting these parts. shall be.

Therefore, according to the present invention, it is possible to prevent the recording paper feeding section from being grabbed in the recording paper feeding direction and near the paper feeding port where paper jams are likely to occur in the printing section, and to reduce the distance from the end of the paper guide to the paper feeding port. It is possible to ensure a large amount of flexure, thereby giving the feeding portion a tendency to actively bend between these. Therefore, paper feeding can be continued no matter which direction the feeding section coming out of the paper outlet is gripped, and paper jams in the printing section can be prevented.
