Abstract

PURPOSE:To enable inlay engagement from an arbitrary position, by constituting the titled apparatus of a guide plate which has a pair of hinge parts and positioning walls formed at both side edges thereof and at least one limit plate slidable on the guide plate corresponding to a paper width. CONSTITUTION:A paper feed apparatus 10 is inclined by a support member 11 while paper width limit plates 121, 122 are attached so as to be made slidable on a guide plate 13 and slid corresponding to a paper width. The limit plate 121 may be fixed without being slid when a printing start position (a left end position) is fixed. In the back surface of the paper feed apparatus, hook parts 121a, 121b, 122a, 122b and spring parts 121c, 121d, 122c, 122d provided to the right paper width limit plate 121 and the left paper width limit plate 122 are respectively opposed and engaged with the upper end surface 133 and the lower end surface 134 of the guide plate 13.

Description

[Detailed description of the invention] (1) Technical field The present invention relates to a paper feeding device used in printers and the like.

(2) Prior Art FIG. 8 shows the appearance of a printer using a conventional separator, which uses continuous slip paper. In this structure, the continuous slip paper 1 is inserted into the case 2 from between the case 2 and the separator 3 of the printer main body, and the internal paper feed 9
The paper is fed out of the case 2 continuously or intermittently by a mechanism so that the paper can be smoothly fed and discharged through the entire upper surface of the separator 6. Therefore, when using Φ method 7 paper (sorting paper), either remove the separator 3 and attach the paper feeder to the hole, or install a paper feeder in a separate location from the separator 5, and then attach the paper feeder to the hole. Paper and cut sheets were used differently.

Further, as shown in FIG. 9, the above-mentioned paper feeding device has a pair of rails 4, a rail holder 5, and a rail guide 6, and a regulating tuff etc. that slides on the rail 4 according to the paper width is provided on the upper part of the rail 4. It consists of

With the above structure, a separator for continuous slip paper and a paper feeder for single slip paper are required separately, and printers such as word processors, which use both types of paper as appropriate, require a lot of effort to attach and detach, making it troublesome to use. . Further, the paper feed device also had a complicated structure and was expensive.

(3) Purpose This invention T'S % This invention was made in view of the above-mentioned disadvantages, and is designed to serve both as a separator for continuous slip paper and as a paper feeder for single slip paper, and to be able to attach and detach when using each paper. The purpose is to eliminate the hassle.

Another object of the present invention is to provide a paper feeding device that has a simple structure and is inexpensive.

(4) Configuration Figure 1 (45) is a perspective view of a printer equipped with a paper feeder 10 according to the present invention, showing a state in which the paper feeder 10 is tilted by a support member 11 and single-purchase paper is used. The paper width regulating plates 121 and 122 are guides, and the paper width is slid over the temporary 13 Mh.
It is attached so that it can be slid depending on the paper width. When the printing start position (left end position) is fixed, the regulation plate 121 may be fixed without sliding.

FIGS. 2 and 3 are diagrams showing paper feeding paths when the paper feeding device of the present invention is used as a paper feeding device for cut sheets and a separator for continuous slip sheets, respectively.

FIG. 4 is a plan view of the paper feeding device of the present invention, showing the guide plate 130.
There are a pair of hinges 132 on each side edge for connecting the tensioner 131 and the printer body.

When kneading, the paper width regulating stone 122 and the left side 1 are on the guide plate 13.
It is attached to the paper and can be freely moved in the direction of arrows A and B to match the width of the paper.

FIG. 5 is a back view of No. 41D, showing the lower end surface 13 of the guide plate 16.
3 and the lower end surface 134, paper width ruler Luri plate right 121 and left 122
Hook parts 121a, 121b and 122a provided in
, 122b, and a spring portion 121c.

121b, 122c, and 122d are opposed to each other and engage with the upper end surface 163 and lower end surface 134 of the guide plate 13, respectively. Moreover, the hook parts 121a, 121b and 12
2a', 1'22b and the spring portions 1210, 121 (1, 122c, 122d) maintain proper spacing, so that one end surface 133 and the lower end surface 134 of the guide plate 13
are maintained at appropriate intervals as above, and the paper width regulation board 1
When sliding between 21 and the left 122, parallel movement is possible. There is a concave 1HB i 3 on the back side of the degree setting 131 on both sides.
s are formed, and support members 11 are respectively mounted and supported by support stops 111. This support member 11 is rotatable as a support holder 111'Jfc fulcrum, and when using all the paper sheets, the support member 11 is rotated and one end 11a is attached to the locking part 2a of the printer main body case ( 1) to stabilize the paper feeder 10 in an inclined state. When using continuous slip paper, the support member 11 is housed in the groove 165.

FIG. 6 is a sectional view taken along the line AA' in FIG. 4, and is taken along the center line of the guide plate 13. Hook portion 12 of paper width regulation plate 121
1b holds the guide plate 13 from the direction of the upper end surface 166. From the direction of the other lower end surface 134 (r), it is always sandwiched by the spring portion 121d.
There is a stepped portion 14 with an L-shaped cross section 1aKU, which serves to prevent the guide plate 16 from coming off.

FIG. 7 is an exploded perspective view of the paper feeding device of the present invention, showing the guide plate 13.
The hinge 132 is located in the hinge hole 1 of the printer body or case.
This shows that it can be installed on the

5- (5) Effects As explained above, the paper feed device η for a printer according to the present invention includes a guide plate having a guide wall and a spring portion having a hook-shaped cross section and opposing each other. It can be fitted and engaged from any position by bending, and can be fixed at any position by the spring portion, providing excellent operability.

Moreover, if the guide sheet metal, the hook part, and the paper width regulating plate with the spring part can be integrally processed using a molded material mainly made of plastic, the appearance will be good, there will be freedom in design, and it will be easy to manufacture at low cost. Can be done.

Furthermore, if the paper feeding device of the present invention is used, there is no need to separately prepare a separator and a paper feeding device, and the trouble of replacing them can be saved. It is very effective in this regard.
