Description

[Detailed Description of the Invention] This invention relates to a paper press stopper device for a printer or the like.

Conventionally, some paper pans that support sheets of various widths that are fed in one direction are equipped with a slideable paper presser stopper so that each sheet of paper is fed with a steady rest.The configuration of this paper presser stopper is as follows. , spot weld a channel-shaped support plate to the bottom of the paper pan perpendicular to the paper feeding direction,
A paper presser stopper made of a bent metal plate is slidably inserted between the support plate and the paper pan and has a guide piece that protrudes from a notch formed in the paper pan and joins to the side edge of the paper. . However, this kind of paper press stopper cannot be attached to the paper pan without a support plate, which has the disadvantage that it requires a large number of parts and is difficult to assemble. As a result, spots are visible and the appearance is poor. Furthermore, since the guide piece is made of a bent metal plate, the finish is poor and the edges may hurt your fingertips.

Furthermore, Japanese Utility Model Application Publication No. 54-54087 has a structure that moves along a slit and has an elastic body in contact with the back surface of the slit portion. however,
The problem with this shape is that it tends to tilt during movement and its movement is not smooth.

Furthermore, in Japanese Utility Model Application Publication No. 56-20941, an elongated lock plate is fitted into the slit to prevent tilting during movement, but the fixing means is a guide rail made of a magnet and magnetic material. The problem is that the structure is complicated.

This invention was made in view of the above points, and the object is to obtain a paper presser stopper device for printers, etc., which is easy to assemble, has a good appearance, and is highly safe.

This invention provides a paper pan that supports paper being fed in one direction, a slit hole perpendicular to the feeding direction of the paper is formed on at least one side of the paper pan, and a slit hole is formed in the side edge of the paper pan, and A fitting part that is slidably inserted into the slit hole and is elongated in the sliding direction, a guide surface that is wider than the fitting part and that is perpendicular to the fitting part and joined to the side edge of the sheet, and a fixed interval between the guide surface and the fitting part. A paper presser stopper is formed by integrally molding an elastic piece made of elastic synthetic resin with an elastic piece having a protrusion at the tip that extends to both sides perpendicular to the guide surface and comes into pressure contact with the lower surface of the paper pan. The elastic piece of this paper press stopper is slidably attached to the paper pan. Therefore, the paper pan is elastically held between the protrusion and the guide surface, the paper presser stopper is easily and directly attached to the paper pan, and supporting members such as support plates are omitted to reduce the number of parts. Spot welding can be omitted to improve the appearance, and since the elongated fitting part is fitted into the slit hole when it is moved along the slit hole, it does not tilt and its movement is smooth. The paper press stopper has a fitting part, a guide surface, and an elastic piece formed by integral molding, making the overall structure extremely simple.Furthermore, the guide surface is made of synthetic resin. The structure is designed to prevent injury to the fingertips and increase handling safety.

An embodiment of this invention will be described based on the drawings. First, a platen 1 held by a frame is provided. A print head 2 facing the platen 1 and paper press rolls 4 and 5 for pressing the paper 3 against the platen 1 are provided.

Then, among the paper 3 to be used, the paper 3 with the highest width
A paper pan 6 wider than the width of the paper pan 6 is provided. A slit hole 7 is formed at the left end of the paper pan 6 and extends in the width direction, which is a direction perpendicular to the feeding direction of the paper 3, and opens on the left side.The paper pan 6 is slid along the slit hole 7. A paper presser stopper 8 is provided to stop the paper 3 from swaying. That is, this paper presser stopper 8 has a horizontally elongated fitting part 9 that is inserted into the slit hole 7 from the opening, and this fitting part 9.
A guide surface 10 that is perpendicular to the paper pan 6 and that contacts the upper surface of the paper pan 6 and joins the side edge of the paper 3
and an elastic piece 12 having a protrusion 11 that is pressed into contact with the lower surface of the paper pan 6 are integrally formed of elastic synthetic resin.

Next, a main body cover 13 covering the frame is detachably attached, and a keyboard cover 16 on which a display 14 and a keyboard 15 are disposed is provided in front of the main body cover 13.

In such a configuration, the lower surface of the guide surface 10 orthogonal to the fitting part 9 inserted into the slit hole 7 of the paper pan 6 is joined to the upper surface of the paper pan 6,
By pressing the protrusion 11 of the elastic piece 12 against the lower surface of the paper pan 6, the paper press stopper 8 is securely fixed to the paper pan 6 while elastically holding the paper pan 6.

Then, the guide surface 10 is pinched to join the side edges of each sheet 3 attached to the right main body cover 13. However, since the guide surface 10 is molded more smoothly than synthetic resin, there is no possibility of damaging the fingertips due to the edges. It can be operated safely. At this time, even if the paper presser stopper 8 is moved too far to the left side of the paper pan 6, the paper presser stopper 8 will not come off from the paper pan 6 because the opening of the slit hole 7 is closed by the main body cover 13.

In this way, the paper presser stopper 8, which has the guide surface 11 that is bonded to each sheet 3 and provides a steady rest, is directly attached to the paper pan 6 as described above, so that the paper presser stopper 8 is not attached to the paper pan 6 as in the conventional case. Although a support member such as a support plate for holding the paper pan 8 is provided, this support plate is not spot welded to the paper pan 6, which reduces the number of parts, makes assembly easier, and has a good appearance without any marks caused by spot welding. It can be done.

Since this invention is constructed as described above, the paper presser stopper can be clamped and attached directly to the paper pan, making it possible to spot-weld the support plate to the paper pan while providing a support member such as a support plate. This makes it possible to reduce the number of parts, facilitate assembly, and improve the appearance. In addition, the elongated fitting part is fitted into the slit hole when it is moved along the slit hole. , it does not tilt and its movement is smooth, and the guide surface is made of synthetic resin with a smooth surface, so there is no risk of hurting your fingertips when making adjustments, increasing safety. It has the following.
