DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording (printing) apparatus, an image forming apparatus, such as a printer, a copying machine, a facsimile, a simple printing machine, and other sheet processing apparatuses. A sheet feeding device effective as a device for feeding sheets (sheets, cut sheets) such as photosensitive paper and printing paper from a stacking and storing section of the sheets one by one into a sheet processing apparatus such as a printer by a feeding means; The present invention relates to a sheet processing device.

[0002]

2. Description of the Related Art Heretofore, as a structure of a sheet stacking and storing section in a sheet feeding apparatus of this type, there are a sheet cassette attaching / detaching type, a sheet table slide-out type, a sheet deck lifting / lowering type, and a fixed sheet tray type.

[0003] In any case, a stack (sheet stack, hereinafter referred to as a sheet bundle) of sheets unpacked or unpacked and unpacked is well separated, and the sheet cassette and the sheet base are aligned in the vertical and horizontal directions. , A sheet deck, and a sheet tray, which are loaded and stored in a predetermined manner.

[0004]

(1) In a conventional sheet feeding apparatus, a sheet bundle which is easily exposed is handled at the time of operations such as storing and removing sheets in a sheet cassette and a sheet table. Poor sheet handling.

[0005] (2) The bare sheet bundle
Sheets may become dirty, scratched or bent when they are separated, vertically or horizontally aligned, stored in a sheet cassette or inside a sheet positioning member such as a sheet table, or taken out in reverse.・ It was easy to break edges.

If the sheet processing apparatus is a recording apparatus or an image forming apparatus, the stain on the sheet surface deteriorates the quality of the output recording / image forming sheet.

[0007] In the case of an ink jet recording sheet as an example, if the coating surface (recording surface) is scratched, ink flows along the scratches or bleeds the ink, causing image defects to occur. Will be generated.

[0008] Folding and edge bending of the sheet may cause skewing of the sheet, sheet jam, and the like in the sheet feeding / conveying path. For example, in an ink jet recording apparatus, the gap between the sheet and the recording head is set to about 1 mm and desirably less than that, so if the sheet is bent or bent, the sheet interferes with the recording head surface and the sheet jam occurs. It is easy to see collapse and dirt caused by rubbing of images and images.

(3) When there is a distinction between front and back sides of a sheet to be used, when the sheets are stacked and stored in a sheet cassette, a sheet table, or the like, the front and back sides are likely to be set in the wrong direction.

In the case of an ink jet recording sheet, for example, the sheet may be a coated paper in which an ink absorbing and retaining layer is coated on plain paper, and an OHP sheet in which a transparent base film such as PET is coated with a transparent ink absorbing and retaining layer.
And a back print film in which a white ink absorption / retention layer is coated with the same structure, a mirror image is printed on the coated surface, and a normal image is obtained when viewed from the back.

In each case, the surface on the coating side of the ink absorption / retention layer is the sheet surface side as the recording surface. The sheet must be stacked and stored with the sheet surface in a predetermined direction (upward or downward) with respect to a sheet cassette or a sheet table so that the sheet surface side faces the recording head so that the sheet is conveyed. .

By printing on the front side of the sheet, the absorbed printing ink is quickly absorbed by the ink absorption holding layer on the sheet surface, and a good printed image is obtained. However, when printing is performed on the back side of the sheet, ink absorption is slow, or ink is not absorbed at all, so that ink flows. In particular, in a color recording apparatus having a plurality of recording heads, printing of a plurality of colors of ink is performed on the same portion of a sheet, so that the amount of adhered ink increases, resulting in further ink flow, color mixing, and the like.

This not only results in a defective image, but also contaminates the transport roller for nipping and transporting the printed sheet that has passed through the recording head section with ink, causing roller stains and defective sheet transport. .

Therefore, when there is a distinction between the front and back sides of the sheet to be used as described above, the sheet must be stacked and stored with the sheet surface side in a predetermined direction with respect to a sheet cassette or a sheet table. Sometimes you make a mistake.

Means for discriminating the front and back of a sheet include: Means for determining from the color difference between the front and back of the sheet; Means for determining based on the difference in the amount of reflected light between the front and back of the sheet; There is a means to determine based on the difference in friction coefficient between the front and back of the sheet.

However, sheets for office use are generally white on both sides, and coated papers are also desired to be white on both sides. The coat thickness is about several tens μm and the texture and surface condition of the paper are poor. It is often difficult or practically impossible to discriminate between the front and back sides based on the color difference and the reflected light amount difference without much difference. In addition, when the friction coefficient of the front and back of the sheet greatly changes due to the environment in which the sheet processing apparatus such as the recording apparatus is installed, particularly due to the temperature and humidity, and furthermore, it differs depending on the sheet material. There are many.

There is a possibility that the same coating is applied to both the front and back surfaces of the sheet to eliminate the difference between the front and back surfaces. However, there is a problem in that the cost of the sheet is increased.

An object of the present invention is to solve the above problems.

[0019]

According to the present invention, there is provided a sheet feeding apparatus and a sheet processing apparatus having the following structures.

(1) A sheet storage body in which a stack of sheets is stored in a container having a closed lid that can be opened and closed can be turned into a sheet feeding port and an action portion of sheet feeding means by opening the lid. A sheet feeding device that is attached to the sheet stacking storage unit with an opening formed and sequentially feeds the storage sheets in the container one by one. The seat is characterized in that mounting is permitted when the mounting is performed in a predetermined direction, and when the mounting is attempted in a different direction, the open lid portion interferes with the sheet stacking storage unit and cannot be mounted. Feeding device.

(2) When the sheet storage body with the lid opened is mounted in the sheet stacking and storing section in a predetermined direction, the opened lid portion is fitted and the mounting of the sheet storage body to the sheet stacking and storing section is performed. (1) The sheet feeding device according to (1), further including a lid fitting recessed portion that allows the sheet feeding.

(3) A sheet processing apparatus which receives a sheet by the sheet feeding apparatus according to (1) or (2).

<Operation> 1) For operations such as storing and taking out sheets to and from the sheet stacking and storing section of the sheet feeding apparatus, a container in which a stack of sheets (a sheet bundle) is stored is handled, and the container itself is handled. By mounting and removing the sheet from the sheet stacking and storing section, the handling of the sheet becomes extremely easy.

2) The user does not directly touch the sheet bundle stored in the container at the time of the above operation, so that the sheet surface may be stained, scratched, bent, bent, or the like. Failures and troubles can be prevented from occurring.

3) The storage sheet bundle in the sheet storage is sealed in the container before the lid is opened, and is protected from environmental changes such as temperature and humidity, dust, dust, etc., and the storage sheet bundle after the lid is opened. The externally exposed part can be made only the necessary minimum part on the tip side, so it can protect against environmental changes such as temperature and humidity, dust and dust, etc. Since the sheet is contained in the container, the degree of progress of moisture absorption / drying of the sheet becomes gentle, and it is possible to prevent the sheet from waving due to a sudden environmental change.

4) At the time of sheet feeding by the operation of the sheet feeding device of the sheet feeding device, the inner surfaces of both side walls of the container act as good side guides over substantially the entire length of the sheet in the sheet feeding direction, and are likely to occur when the sheet feeding device feeds the sheet. The occurrence of skewing of the sheet is prevented.

5) When the sheet storage unit is removed from the sheet stacking storage unit during use, the remaining sheet is kept sealed in the sheet storage unit by closing the rotation opening / closing lid with respect to the sheet storage unit main body. It can be protected from environmental changes, garbage and dust until the next use.

6) When the sheet storage unit with the cover opened is mounted in the sheet stacking storage unit in a predetermined direction, mounting is permitted, and when the sheet storage unit is mounted in a different direction, the sheet storage unit is opened. The lid part that interferes with the sheet stacking storage unit and cannot be attached because the opening / closing pivotable lid on the sheet storage unit side and the lid fitting recess on the sheet stacking storage unit side move the sheet storage unit to the sheet stacking storage unit. It becomes a mechanical fool-proof for mounting in the predetermined direction without fail, thereby making it possible to strictly prevent the occurrence of printing on the back surface of the sheet.

(3) Ink Jet Recording Method The ink jet recording method adopted in the recording apparatus 200 shown in FIGS. 1 and 2 will be briefly described.

The non-impact recording method has recently attracted attention in that the generation of noise during recording is extremely small to a negligible level. Among them, there is a possibility of high-speed recording, and an ink jet recording method capable of performing recording on so-called plain paper without requiring a specific fixing process is an extremely effective recording method.

A recording head applied to an ink jet recording apparatus generally has a fine liquid ejection port (orifice), a liquid path, an energy action section provided in a part of the liquid path, and a liquid acting on the action section. An energy generating means for generating energy for forming droplets is provided.

As an energy generating means for generating such energy, a recording method using an electromechanical transducer such as a piezo element or the like, irradiation of electromagnetic waves such as a laser, absorption of a liquid there to generate heat, A recording method using energy generating means for discharging and flying droplets by the action of heat generation, or using an energy generating means for discharging liquid by heating the liquid with an electrothermal converter such as a heating element having a heating resistor. There are recording methods and the like.

Among them, a recording head used in an ink jet recording method for discharging a liquid by thermal energy has a high density liquid discharge port (orifice) for discharging a recording liquid droplet to form a flying liquid droplet. Since they can be arranged, it is possible to record at a high resolution.
Among them, a recording head using an electrothermal transducer as a means for generating thermal energy can easily be made compact as a recording head as a whole, and has recently achieved remarkable advances in technology and reliability in the semiconductor field, such as IC technology and microelectronics. It is possible to make full use of the advantages of the processing technology, and it is easy to make it multi-nozzle and high-density mounting because it is easy to make it longer and more planar (two-dimensional). It is possible to provide an inkjet and recording head which is inexpensive to manufacture and an apparatus having the head.

Here, the ink flying principle of the ink jet recording system will be described with reference to FIGS.

In the steady state, as shown in FIG. 7A, the surface tension and the external pressure of the ink filled in the nozzle d are balanced at the discharge port surface. When the ink is caused to fly in this state, electricity is supplied to the electrothermal converter c in the nozzle d to cause the ink in the nozzle d to rapidly rise in temperature over the film boiling. Then, as shown in (b), the ink adjacent to the electrothermal converter c is heated to generate fine bubbles (bubbles), and the ink in the heated portion is vaporized to cause film boiling, as shown in (c). The bubbles grow rapidly.

When the bubble grows to the maximum as shown in (d), the ink droplet is pushed out from the discharge port in the nozzle d. Then, when the energization of the electrothermal transducer c is terminated, the grown air bubbles are removed from the nozzle d as shown in FIG.
The ink droplets are cooled and shrunk by the ink inside, and the ink droplets fly from the ejection ports due to the growth and shrinkage of the bubbles. Further, as shown in (f), the ink is brought into contact with the surface of the electrothermal transducer c and rapidly cooled, and the bubbles disappear or shrink to a volume that can be almost ignored. When the bubble shrinks, ink is supplied from the common liquid chamber into the nozzle d by capillary action as shown in (g) to prepare for the next energization.

Accordingly, the ink image is recorded on the recording sheet by reciprocating the carriage and energizing the electrothermal transducer c according to the image signal in synchronization with the movement.
