Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] The present invention relates to a paper setting device for a cut-sheet printer provided with a positioning means for setting cut-sheet paper at a predetermined printing position. The load applying means for applying a load resisting the movement of the cut sheet set at a predetermined printing position has a shape inclined in the direction of inserting the cut sheet. It is assumed that.

[Industrial applications]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet setting apparatus for a cut sheet printer having positioning means for setting a cut sheet at a predetermined printing position, and more particularly to a sheet setting apparatus having improved cut sheet positioning accuracy and operability.

[Conventional technology]

2. Description of the Related Art Conventionally, in a cut sheet printer, sheet setting is generally performed manually by an operator.

Regardless of automatic or manual, when the cut sheet is set at a predetermined printing position, the cut sheet is positioned by the following method.

FIGS. 4A and 4B are a plan view and a side view showing a general example of a sheet setting device. As shown in both figures, the cut sheet 1 is placed on the horizontal surface of the printing table 2 and abuts by hand of the operator against the abutting members 3 and 4 as positioning means in the row and column directions of printing. After that,
The feed roller 5, which was open before the conveyance, is closed and the abutting member 3
The setting of the cut sheet has been completed by retracting the sheets 4 and 4.

[Problems to be solved by the invention]

In the sheet setting apparatus as described above, the printing position accuracy on the cut sheet is determined by the setting position of the cut sheet by the abutting members 3 and 4.

However, as shown in FIG. 5, the cut sheet 1 is brought into contact with the abutment member 3 by the operator's hand, and the operator who confirms that the cut sheet 1 has been released releases his hand from the cut sheet 1, If the way of separation is not careful, the cut sheet moves and separates from the butting member 3 or tilts. When the feed roller is closed while the position of the cut-sheet paper is out of order,
A cut sheet setting failure occurs, and the accuracy of the printing position is reduced.

Also, as shown in FIG.
In the case of a structure where the section provided with is inclined, even if the operator puts his hand off the cut sheet 1 even if the operator hits the cut sheet 1 against the abutting member 3, the cut sheet 1 is indicated by an arrow in the figure. The operator must keep holding the cut sheet until the feed roller 5 closes and presses the cut sheet.

However, if a large holding means is provided in this portion, it becomes a hindrance, and it becomes difficult to set the cut sheet easily, and the operability is reduced.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a sheet setting device of a cut-sheet printer that improves positioning accuracy and operability of cut sheets.

[Means for solving the problem]

In the present invention, a means for achieving the above object and solving the problem is provided in a sheet setting device of a cut-sheet printer provided with a positioning means for setting a cut sheet at a predetermined print position. A sheet setting device for a cut sheet printer, wherein the load applying means for applying a load resisting the movement of the set cut sheet has a shape inclined in a direction of inserting the cut sheet. It is.

[Action]

In the present invention, for example, the friction between the printing table and the cut sheet is increased by applying a load to the cut sheet by the load applying means having a shape inclined in the direction of inserting the cut sheet as shown in the figure. To provide resistance to the movement of the cut-sheet paper set at a predetermined printing position, and shift, tilt, and the like from the position where the operator abuts the positioning means.
And prevent slipping.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a structural diagram showing an example of a sheet setting device of a cut-sheet printer embodying the present invention. As shown in FIG. 1, when the cut sheet placing surface of the printing table 2 of the cut sheet printer is inclined and the abutment member 3 as positioning means is disposed at the vertex thereof, A pressing plate 7 having a shape inclined in the inserting direction of the cut sheet 1 is provided as a load applying means on the feed path of the cut sheet 1 so as to apply a load to slip of the cut sheet 1. This holding plate 7
Is a position where the cut sheet 1 is abutted against the abutting member 3 even if the operator releases his / her hand while lightly contacting the upper surface of the cut sheet with a minute load that does not hinder the feeding of the cut sheet. From falling off.

When the cut sheet 1 is inserted, the press plate 7 may be in the way. However, since the press plate 7 is inclined in the insertion direction of the cut sheet 1, the load is hardly applied, and the cut sheet is removed. A large load is applied only when trying to slide down.

FIG. 2 shows a load applying means 8 in which a plurality of holding plates are provided, and FIG. 3 is a structural diagram showing a specific example thereof. The direction of the cut sheet 1 is laid on the insertion side of the cut sheet 1 so that the cut sheet 1 can be easily inserted, and only the drop is prevented.

〔The invention's effect〕

As described above, according to the present invention, according to the present invention, the load applying means for applying a load resisting the movement of the cut sheet set at the predetermined printing position is inclined in the cut sheet inserting direction. Since it is a paper setting device of a cut-sheet printer having a shape, when setting the cut-sheet paper at a predetermined print position via the positioning means, release the hand from the cut-sheet paper set at the predetermined print position. However, since the cut sheet is pressed by the load applying means, the cut sheet does not move and is separated from the positioning means or tilted, so that the position of the cut sheet is not disturbed.
