Description

[Detailed explanation of the invention] Technical field of the invention This invention relates to a recording paper guide for a printer.
For example, the present invention relates to a recording paper guide for guiding a roll of recording paper to a printer installed in an electronic cash register (ECR).

Description of Prior Art The ECR is equipped with a printer for printing sales information and the like on a roll of recording paper. In such a printer, when the recording paper runs out, it is necessary to replenish the recording paper with new recording paper.
However, since it is necessary to push out the printed recording paper from the front of the ECR, the roll of recording paper on which sales information has not yet been recorded is configured to be loaded from the back of the ECR. For this reason, you have to lean forward from the front side to load the recording paper, and since the recording paper is wound in a roll, the leading edge of the paper tends to lift up.
It is necessary to insert it while preventing it from floating up, which has the disadvantage of being complicated.

Purpose of the Invention Therefore, the main purpose of the present invention is to provide a recording paper guide for a printer that can facilitate loading of a roll of recording paper.

Structure and Effects of the Invention To summarize this invention, a roll paper winding section, a printer section, and a roll paper storage section are arranged from the side in front of the operator to the other side, and the roll paper storage section is placed above the roll paper storage section. A guide member is provided at. This guide member includes a rotating part that can rotate around the border between the roll paper storage section and the printer section, an uneven part formed around the rotating part, and a recording paper inserted from the free end of the rotating part. A prevention portion for preventing the recording paper from lifting is provided along both ends in the direction. A locking mechanism is provided on the printer side of the guide member, and this locking mechanism abuts against the uneven portion of the guide member to maintain the guide member in a substantially horizontal or inclined state. In the normal state in which the printer section operates, the guide member is kept in a nearly horizontal state by the lock mechanism, and when the roll paper is loaded, the guide member is kept in an inclined state with its free end facing diagonally upward by the lock mechanism. The leading end is inserted from the free end of the guide member and wound up on the winding section via the printer section.

Therefore, according to this invention, when the guide member is tilted when loading the roll paper, the free end of the guide member, that is, the roll paper insertion opening approaches the person inserting the roll paper, and the insertion direction is diagonally downward. As a result, the distance you can reach becomes shorter, and
The insertion slot becomes easier to see, and the leading edge of the recording paper is prevented from lifting up by the guide member, making it easier to mount the recording paper in the printer.

This invention will be explained in more detail below along with embodiments shown in the drawings.

DESCRIPTION OF EMBODIMENTS FIG. 1 is a diagram for explaining the outline of this invention. In Figure 1, the ECR main body 1 is
is placed on top of the A printer 11 is built into the ECR main body 1, and a lid 12 is provided on the back side of the ECR main body 1 so as to be openable and closable. This lid 12
By opening it, a roll of recording paper is loaded. A recording paper guide 3, which is a feature of this invention, is provided on the printer 11 side within the ECR main body 1. This recording paper guide 3 guides the recording paper to the printer 1.
1, the distal end thereof can be easily inserted into the insertion opening (not shown) of the printer 11, and a locking mechanism is provided to prevent rotation at a predetermined angle.

Fig. 2 is a side view of a printer to which an embodiment of this invention is applied, Fig. 3 is an external perspective view of an embodiment of this invention, and Fig. 4 is a side view of a printer to which an embodiment of this invention is applied. FIG.

First, referring to FIG. 2, the printer 11 is provided with a head section 111 at the top, a storage section 112 for storing the roll-shaped recording paper 4 before printing at the lower left, and a storage section 112 at the lower right. is printed recording paper 5
Printed recording paper storage unit 113 wound into a roll
is provided. The recording paper guide 3 is provided on the storage section 112 side of the printer 11.

The recording guide 3 includes a flat guide bottom plate 31, as shown in FIG. This guide bottom plate 31 has prevention plates 3 for preventing the recording paper 4 from floating up along both side edges in the insertion direction of the recording paper 4.
2, 32 are formed. Furthermore, the guide bottom plate 31
At the end of the printer 11, when the recording paper guide 3 is locked upward as shown in FIG.
A plate spring 33 formed in an arc shape is provided to close the gap between the recording paper guide 3 and the printer main body 11 and to guide the recording paper 4 to the printer insertion slot. Furthermore, arms 34 are formed to extend from the end of the recording paper guide 3 on the printer 11 side.
A hole 35 is formed at the tip of the arm 34 into which a rotation shaft (not shown) is inserted to allow the recording paper guide 3 to rotate, and a protrusion 36 is formed around this hole 35. It is formed. This protrusion 36 together with the leaf spring 6 attached to the printer body 11 constitutes a locking mechanism. That is, the circumference of the hole 35 is formed in an arc shape, and three protrusions 36 are formed thereon. When this protrusion 36 comes into contact with the leaf spring 6, the recording paper guide 3 is moved by the elastic force of the leaf spring 6.
The function is to hold it at a predetermined angle.

By providing the recording paper guide 3 as described above, mounting of a new recording paper 4 becomes easy. That is, when loading recording paper into the storage section 112, open the lid 12 as shown in FIG. Protrusion 3 of the locking mechanism
6 to prevent the recording paper guide from rotating at a predetermined angle. Then, the leading end of the recording paper 4 is inserted into the recording paper guide 3 from the open end side. At this time, the prevention plate 3 prevents the leading edge of the recording paper 4 from rising.
2, the recording paper 4 is smoothly inserted into the insertion slot of the printer 11. After inserting the recording paper 4 into the printer 11 and making a trial print, the recording paper guide 3 is returned to its original horizontal state and the lid 12 is closed.

As described above, according to this embodiment, by providing the recording paper guide 3, when installing the roll-shaped recording paper 4, the user takes an unnatural posture of leaning forward from the front side. The recording paper 4 can be loaded extremely easily without any trouble.
