Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a paper guide device for a cash register.

2. Description of the Related Art As shown in FIG. 6, in a cash register, a slit-shaped receipt issuing passage 31 is formed on the upper surface of a casing 30 of the cash register in order to enable printing on slip paper. There is one whose length is considerably longer than the width of receipt paper 1. Further, although the receipt paper 1 is cut by the cutter 32, if it is not removed immediately after cutting, the receipt paper 1 will be cut by the casing 30.
may fall or fly inside. For this reason, the cutter 32 has been devised as shown in FIG.
A part 2 that is not cut is formed in a part of the receipt paper 1. This receipt paper 1 is pulled in the direction of the arrow in FIG. 6 to tear off the uncut portion 2 of the receipt paper 1. In addition, some operators may want to place their hands on the receipt issuing path 31 in order to quickly retrieve the issued receipt paper 1.
As a result, the receipt paper 1 does not advance upwards and a paper jam occurs inside. For this reason, a paper guide 33 located on one side in the width direction of the receipt issuing path 31 is provided in the housing 30, and even if the leading edge of the receipt paper 1 is pressed by hand on the paper guide 33, the receipt paper 1 is Some paper sheets are designed to allow ejection from the receipt issuing path 31 even if the guide 33 is curved inside or at the front, thereby preventing paper jams inside.

Problems that the invention aims to solve However, although it is fine if the receipt paper 1 is pulled in the direction of the arrow in FIG. When the receipt paper 1 is fed by the feed roller 34 and the pinch roller 35, it meanderes and is printed diagonally.

This invention was made in view of the above points, and an object thereof is to provide a paper guide device for a cash register that can prevent paper jams and meandering of receipt paper.

Means for Solving the Problem A slit-shaped receipt issuing path is formed on the top surface of the casing, into which a receipt paper to be cut by a cutter and a slip paper having a width wider than the width of the receipt paper are inserted, leaving a part intact. A container-shaped paper guide with an opening at the lower end that covers the upper part of the receipt issuing path is provided, and a horizontally elongated window having a length approximately equal to the width of the receipt paper is formed on the upper surface of the paper guide to selectively issue the receipt paper. The paper guide is rotatably connected to the upper surface of the casing by a hinge so as to open the issuing path, and the paper guide is formed with a curved surface whose radius is centered around the center of rotation, and the upper surface of the casing is A projection is formed on a part of the curved surface to resiliently abut the paper guide and stabilize the paper guide at a position covering the receipt issuing path.

Effect Therefore, when issuing receipt paper,
The paper guide window prevents side-to-side wobbling and the meandering of receipt paper caused by this wobbling.
Allows the receipt paper to bend inside the paper guide to prevent paper jams inside the receipt issuing path,
Further, when issuing a normal receipt, the paper guide is stabilized in a position covering the receipt issuing path due to the frictional resistance caused by the contact between the protrusion and the upper surface of the casing. Furthermore, by rotating the paper guide and opening the entire length of the receipt issuing passage, it becomes possible to insert wide slip paper into the receipt issuing passage.

Embodiment An embodiment of this invention will be described based on FIGS. 1 to 5. Reference numeral 3 denotes a housing of the cash register. Inside the housing 3, a long receipt paper 1 and journal paper (not shown) are wound and held in a roll shape, and a platen 4 is held.
A printing head 5, a feed roller 6, a pinch roller 7, and a cutter 8 are provided. As shown in FIG. 5, the cutter 8 has a notch formed in the center of the blade so that an uncut portion 2 is formed in a portion of the receipt paper 1. A long slit-shaped receipt issuing passage 9 is formed on the upper surface of the housing 3 to allow insertion of wide slip paper (not shown).

Next, on the top surface of the housing 3, there is provided a paper guide 10 shaped like a container with an opening at the bottom and whose internal space becomes wider in the front-rear direction as it goes downward. This paper guide 10 is located at a position covering the receipt issuing path 9 and is connected to the housing 3 by a hinge 11 so as to be vertically movable. A horizontally long window 12 having a length that substantially matches the width of the receipt paper 1 is formed on the upper surface of the paper guide 10, and a curved surface 13 whose radius R is centered around the pivot point of the paper guide 10 is formed on the lower front edge. It is formed. This curved surface 13 has a radius R that forms a gap with respect to the upper surface of the housing 1, and a projection 14 is formed in a part of this curved surface 13. The distance from the pivot point of the paper guide 10 to the tip of the protrusion 14 is set to be slightly larger than the shortest distance from the pivot point of the paper guide 10 to the upper surface 15 of the housing 3. In order to normally stabilize the paper guide 10 in a position covering the receipt issuing path 9, the upper surface 1 of the housing 3 is placed directly below the paper guide 10, as shown in FIG.
The projection 14 is positioned forward of a straight line 16 passing through the center of the hinge 11 perpendicularly from the hinge 11.

In such a configuration, when issuing a receipt, the printed receipt paper 1 is fed upward by rotating the feed roller 6. At this time, if the user carelessly presses the upper edge of the receipt paper 1, the receipt paper 1 will be curved, but will remain in the internal space of the paper guide 10 and will not be pushed into the housing 3. Thereby, paper jams inside the receipt issuing path 9 can be prevented. When operating the cutter 8 to cut the receipt paper 1 leaving only a part and pulling the receipt paper 1 to tear off the uncut portion 2, the receipt paper 1 can be cut even if the receipt paper 1 is carelessly pulled in the left and right direction. Since it is supported by both the left and right sides of the window 12 of the paper guide 10, it does not bend in the left-right direction. Therefore, meandering of the receipt paper 1 can be prevented no matter how it is stretched.

When inserting wide slip paper into the receipt issuing path 9 and printing, rotate the paper guide 10 upwards around the hinge 11 and insert the paper into the receipt issuing path 9.
is released over its entire length. At this time, since the protrusion 16 moves from the front to the rear of the straight line 16, the resistance force for rotating the paper guide 10 temporarily increases;
This resistance suddenly weakens at the next moment, making it easier to operate. That is, the rotational movement of the paper guide 10 can be moderated, and the paper guide 10 can be stabilized during normal receipt issuing.

Effects of the invention Since this invention is constructed as described above, when issuing receipt paper, the window in the paper guide prevents side-to-side deflection and meandering of the receipt paper caused by this deflection, and the inside of the paper guide It is possible to prevent paper jams inside the receipt issuing path by allowing the receipt paper to bend, and when issuing normal receipts, the frictional resistance caused by the contact between the protrusion and the top surface of the casing prevents the receipt from becoming jammed. The paper guide can be stabilized in a position covering the issuing path, and by rotating the paper guide and opening the entire length of the receipt issuing path, wide slip paper can be inserted into the receipt issuing path. It has the effect of
