Here, by cutting off the cleaning paper piece 801 from the groove 81, a part, which can not be used by most sticking of the adhering matter, is removed, and the paper is made reusable.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a cleaning sheet used for removing a deposit on a sheet feeding member of a sheet feeding / feeding device.

[0002]

2. Description of the Related Art Conventionally, in a paper feeding / paper feeding device such as a printing device, a cleaning means for removing a deposit on a paper feeding member which applies a force for feeding the paper in contact with the paper is used.
A cleaning sheet has been used in which an adhesive layer is formed on the surface of paper or the like, and the sheet is fed in the same manner as the sheet to remove deposits on the sheet feeding member.

[0003]

With such a cleaning paper, it is not possible to remove the deposits by one cleaning paper pass, and a plurality of cleaning paper passes are required for sufficient cleaning. However, there is a problem that a plurality of cleaning sheets are required.

[0004] Since the portion with a large amount of deposits is the portion where the sheet first hits the sheet feeding member where the force is likely to be applied,
This is because the vicinity of the leading edge of the cleaning paper serves as a cleaning function by attaching an adhered substance, and the cleaning function is lost, and the cleaning paper cannot be used. On the other hand, most of the other parts have to be discarded in spite of the fact that they still have a sufficient adhesive function, and there is a problem that the cleaning paper is wasted.

Further, in a range in which the sheet feeding member hits in the width direction of the sheet, there are a member for pressing and feeding the entire surface of the sheet and a member for pressing and feeding a part of both ends of the sheet. The width direction is not uniform.
For this reason, for example, in the cleaning of a member to be fed while pressing both ends of the sheet, there is a problem that the central side of the cleaning sheet is not used and is wasted.

The present invention solves such a problem, and realizes a cleaning sheet that can be used without waste by eliminating unused portions.

Although not shown in the figure, a mechanism for holding a plurality of sheets of paper 10 on the sheet holding plate 6 and pressing the sheet of paper 10 against the paper feed roller 1 is provided, and between the sheet holding plate 6 and the sheet guide 7. And a separation mechanism for separating the sheets 10 one by one.

The paper 10 set on the paper holding plate 6 is
The paper is pressed by the pressing mechanism of the paper holding plate 6 against the paper feed roller 1, and the paper is fed by the rotation of the paper feed roller 1.
The paper 10 is separated by the separation mechanism and only one sheet is fed. When the paper 10 reaches the paper feed roller 2 and the paper feed auxiliary roller 21 along the paper guide 7, the paper 10 is sandwiched between the paper feed roller 2 and the paper feed auxiliary roller 21, and is sent by the rotation of the paper feed roller 2. . At this time, the contact between the paper feed roller 1 and the paper 10 is released as shown in FIG.
Zero wrinkles and breaks are prevented.

In the state as shown in FIG. 2, the print head 4 scans in the width direction of the paper 10 and the paper 10 is fed by the paper feed roller 2 to print on the surface of the paper 10. At this time, the paper 10 is being fed by the rotation of the paper feed roller 2, and the paper discharge roller 3 and the paper discharge auxiliary roller 31 are provided with a slip mechanism (see FIG. 1) provided in a transmission mechanism for transmitting a driving force to the paper discharge roller 3. (Not shown), the sheet 10 is fed by a very small force, and plays a role of keeping the sheet 10 in a constant posture and position. When the sheet 10 comes off the sheet feed roller 2 and the sheet feed auxiliary roller 21, the sheet 10 is sent by the sheet discharge roller 3 and the sheet discharge auxiliary roller 31, and is discharged.

FIG. 4 is a plan view showing the positional relationship between the sheet feeding roller 1 and the sheet holding plate 6, wherein 5 and 51 are sheet side guides, 11 is a sheet feeding roller, and 61 is a sheet holding plate. FIG.
Is a plan view of an example of a mechanism having one paper feed roller, 52 and 53 are paper side guides, 12 is a paper feed roller, and 62 and 63 are paper holding plates.

FIG. 6 is a plan view of the cleaning paper 8.
Reference numerals 1 and 82 denote grooves formed at a depth of several tenths of the thickness of the cleaning paper 8, and reference numerals 801, 802, and 803 denote grooves 81.
And 82 are the cleaning paper pieces divided by. FIG. 7 is a plan view of the cleaning paper 9,
Reference numerals 3 and 94 designate grooves 901, 902, 903, 904, and 9, respectively, which are formed at a depth of several tenths of the thickness of the cleaning paper 9.
Reference numeral 05 denotes a cleaning sheet piece divided by the grooves 91, 92, 93, and 94.

The cleaning of the paper feed roller and the paper feed roller by the cleaning paper can be performed by feeding the cleaning paper in the same manner as the paper. When the cleaning paper 8 is fed in the direction of arrow a in FIG. 6, first, the paper feed rollers 1 and 11 come into contact with the cleaning paper 8 and the deposits on the paper feed rollers 1 and 11 adhere to the cleaning paper 8. The contact between the paper rollers 1 and 11 and the cleaning paper 8 is approximately until the cleaning paper 8 reaches the paper feed roller 2 and the paper feed auxiliary roller 21. The range in which the deposits adhere is the range shown by 101 and 102 in FIG. On the other hand, the paper feed rollers 1 and 11 also contact the cleaning paper 8 only once, and it cannot be expected that all the attached matter will be removed.

Next, the paper feed roller 2 and the cleaning paper 8 come into contact with each other and the deposits on the paper feed roller 2 adhere to the cleaning paper 8, but since the width of the paper feed roller 2 is wider than the width of the cleaning paper 8, The deposit on the paper feed roller 2 adheres over the entire width of the cleaning paper 8. Further, since the paper feed roller 2 must be rotated several times in order to feed the cleaning paper 8, the surface of the paper feed roller 2 is cleaned several times, and the top of the cleaning paper 8 which comes into contact first Many deposits adhere to the side,
There is almost no deposit on the end side. here,
By separating the cleaning paper piece 801 from the groove 81, the part that has become unusable due to the most adhered matter can be removed, and the cleaning paper 8 can be used again. Although it is possible to pass the cleaning paper 8 from the opposite direction, the paper feed roller 2 that has been cleaned once comes into contact with a portion where a large amount of the adhered substance adheres,
Deposits can be returned, which is not desirable.
Separating the cleaning paper piece 801 from the groove 81 according to the present invention also has the effect of preventing attached matter from returning.

When the cleaning paper 9 is fed in the direction of the arrow b in FIG.
The range in which the first deposit adheres is the range indicated by 201 and 202 in FIG. By separating the cleaning paper pieces 901 and 905 from the grooves 91 and 94, a portion that has become unusable due to the most adhered matter can be removed and the cleaning paper 9 can be used again. In an apparatus having one paper feed roller as shown in FIG. 5, the cleaning paper 9 is more effective.

In the above, the embodiment in which the groove of the separating means is inserted in a direction parallel to the direction perpendicular to the sheet feeding direction has been described. Of course there is.

Further, in order to reliably feed the paper, it is necessary that the end face condition and shape of the paper are at a certain level or more, and the paper may not be fed with scissors. Since the cleaning paper according to the present invention is separated using grooves or perforations, the end face condition after the separation can easily have a certain level of linearity, fluffing, and the like, and a paper feeding problem occurs. Can be prevented beforehand.

[0020]

According to the present invention, a separation means such as a perforation is provided in a direction perpendicular to the sheet feeding direction so that the sheet can be divided in the sheet feeding direction, so that only a very dirty portion near the leading end can be cut off. Therefore, there is an effect that one cleaning sheet can be used a plurality of times. In addition, by providing separation means such as perforations in a direction parallel to the paper feeding direction and enabling division in a direction perpendicular to the paper feeding direction, only the used portion in the width direction can be cut off. There is an effect that the cleaning sheet can be used a plurality of times. These effects lead to the effect that one cleaning sheet can flexibly cope with the case where a plurality of cleaning passes are required to sufficiently remove the deposits, which is very useful.
