Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to printers. In particular, the present invention relates to improvement of a manual feed port for manually feeding paper.

[0002]

2. Description of the Related Art FIG. 5 shows the appearance of a conventional general printer.

In the figure, 1 is a printer case and 2 is a printer case.
Is a manual feed slot, and 3 is a paper guide for guiding the paper P.

In the conventional printer, the manual paper guide 3 is formed to project from the case 1.

[0005]

In the conventional printer described above, the paper guide 3 for manual feeding is formed so as to project from the case 1. Therefore, there is a problem that the paper guide 3 becomes an obstacle especially when not in use. It was

A first object of the present invention is to solve the above problems and provide a printer in which the paper guide does not interfere.

A second object is not only to prevent the paper guide from getting in the way but also to make it easy to insert the paper.

[0008]

In order to achieve the first object, a printer according to a first aspect of the present invention is provided with a printing unit provided in a case, and a paper for manually feeding the printing unit. It is characterized in that it has a manual feed port, and the paper guide at this manual feed port is formed toward the inside of the case.

In order to achieve the second object, the printer according to a second aspect is the printer according to the first aspect, in which the manual feed port is formed in an elongated rectangular shape, and there are two longitudinal edges. It is characterized in that at least one of the edges is formed lower than the other edges.

A printer according to a third aspect is the printer according to the first or second aspect, wherein a rib is formed on the guide surface of the paper guide.

Further, a printer according to a fourth aspect is the printer according to the first, second or third aspect, in which a manual feed port is formed on the rear of the upper surface of the case, and the printing portion and the manual feed port have a large curvature. It is characterized by connecting with.

[0012]

According to the printer of the first aspect, since the paper guide at the manual feed port is formed toward the inside of the case, the paper guide does not interfere.

According to the printer of the second aspect, the manual insertion port is formed in an elongated rectangular shape, and at least one of the two longitudinal edge portions is lower than the other edge portions. Since it is formed, even if the paper guide at the manual feed port is formed toward the inside of the case, the paper can be easily inserted due to the lower edge portion in the longitudinal direction. Further, according to the printer of the third aspect, since the rib is formed on the guide surface of the paper guide, when the paper is inserted,
The ribs cause the paper to float from the guide surface, making it easier to insert the paper.

Further, according to the printer of the fourth aspect, since the manual feed port is formed on the rear side of the upper surface of the case, and the printing unit and the manual feed port are connected by the manual feed path having a large curvature, the paper having high rigidity is provided. But you can plug it in easily.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of a printer according to the present invention, FIG. 2 is a front view, FIG. 3 is a plan view, and FIG. 4 is a rear view.

In these drawings, reference numeral 100 denotes a printer case, which includes a lower case 110 and an upper case 120.

Reference numeral 60 denotes a printing section, which is an ink jet head 62 mounted on a carriage 61 which reciprocates in a direction orthogonal to the paper surface in FIG. 1, and an intermediate frame 130.
It is formed between the upper surface and. 63 is a carriage 61
Is a guide shaft that guides one end of the carriage 61, and 140 is an upper frame that guides the other end of the carriage 61.

Reference numeral 30 denotes a paper feed roller that feeds the paper to the printing unit 60, and 50 denotes a pinch roller that presses the paper feed roller 30 and is driven thereby. Paper feed roller 30 and pinch roller 5
The paper that has been sent to the printing unit 60 by 0 and printed is discharged onto the paper discharge tray 150 via the conveyance unit 80 and the discharge unit 90.

This printer is provided with an automatic paper feed path 20 and a manual paper feed path 21 as a path for feeding the paper between the paper feed roller 30 and the pinch roller 50.

First, the automatic sheet feeding side will be described. 10
Is an automatic paper feeder, and 40 is a gate roller which is pressed against the paper feed roller 30 and is driven thereby. In the automatic paper feeder 10, a stacker for the paper P is directly formed by the bottom portion 111 of the lower case 110 of the printer. When automatic sheet feeding is performed, the sheet P is automatically fed sheet by sheet 20 one by one by the operation of the sheet feeding roller 12 provided only in the central portion.
Be delivered to. When the paper feed roller 12 is rotating, the fed paper is fed in a plan view with its leading end being pressed between the paper feed roller 30 and the gate roller 40, which rotate in the opposite direction to the paper feed direction. The skew is removed by rotating around the roller 12 part, and thereafter, it is wound around the paper feed roller 30 which rotates in the paper feed direction, and reaches the printing portion 60 via the pinch roller 50.

Next, the manual sheet feeding side will be described.

Reference numeral 121 is a manual insertion port formed on the rearmost side of the upper surface of the case. The paper guide 12 is provided in the manual feed port 121.
2, 123, 124, and 125 are formed integrally with the upper case 120 and toward the inside of the case. The paper guides 122 and 123 guide the front and back surfaces of the paper, and 124 and 125 guide the side edges of the paper.

As shown in FIG. 3, the manual feed port 121 is formed in an elongated rectangular shape, and has two longitudinal edge portions 122a and 123a (that is, the paper guides 122 and 1).
Paper guide 1 out of the upper edge portions 122a, 123a of 23
22 upper edge portion 122a to other edge portions 123a, 124
It is formed lower than a and 125a.

Ribs 122b are formed on the guide surface of the paper guide 122.

The above-mentioned manual paper feed path 21 is formed with a small curvature so that the paper inserted through the manual paper feed opening 121 is guided to the printing section.

Reference numeral 22 denotes a paper detection lever that faces the manual paper feed path 21, and is rotated counterclockwise when the paper passes through the manual paper feed path to detect the paper.

According to the printer as described above, the paper guides 122, 123, 124, 1 at the manual feed port 121 are provided.
Since 25 is formed toward the inside of the case, the paper guide does not get in the way.

Further, the upper edge portion 122a of the paper guide 122 is
Is formed lower than the upper edges of the other guides, it is easy to insert the paper, and especially when inserting a short paper, the front end of the paper is fed by the paper feed roller 30 and the pinch roller 50.
It can be inserted securely until it reaches between and.

Since the manual paper feed path 21 is curved as shown in FIG. 1, the front part of the paper is the manual paper feed path 21.
The rear of the paper is urged toward the paper guide 122 as it enters the
Since the sheet 2b is formed, the rib 122b causes the sheet to float from the guide surface, which facilitates insertion of the sheet. In particular, even when inserting a short sheet, it is possible to surely insert the sheet to the end with the fingertip.

Further, since the manual feed port 121 is formed on the rearmost side of the upper surface of the case, the curvature of the manual paper feed path 21 can be reduced, and even a strong paper can be easily inserted.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention.

[0033]

According to the present invention, the paper guide can be kept out of the way and the paper can be easily inserted.
