Description

[Detailed Description of the Invention] - "Industrial Application Field" The present invention relates to a sheet material storage tray, and in detail, for example,
The present invention relates to a sheet material storage tray that is installed as a paper discharge section of a recording device such as a facsimile or a copying machine, and stores recording sheet materials on which images have been formed and which are discharged from an image forming section.

[Prior Art] A recording sheet storage tray for recording sheets on which images have been formed, which is installed in a facsimile machine, a copying machine, or the like, is generally provided in a manner that projects from the main body of the apparatus. FIG. 2 shows an example of a facsimile machine equipped with such a recording sheet storage tray.

In the figure, l is the main body of the facsimile machine, and the second document
An information reading and transmitting system that reads the information on the document 3 sent over the top by a reading section 4 configured to convert it into an electrical signal by a photoelectric conversion element 4c such as a CCD via mirrors 4a and 4b, and transmits the information, and a recording paper. The information receiving and recording system includes a recording spatula 1-8 for recording received information onto a recording sheet 7 fed out from a roll 5 by a platen roller 6.

In the figure, a document storage tray 9 is provided on the left side of the facsimile main body 1 to store the document 3 sent from the document section 2, and a document storage tray 9 is provided on the right side of the facsimile main body 1.
A recording sheet storage 1-lay 11 for storing an image-formed recording sheet 7 on which an image is recorded by the recording head 8 and cut into a predetermined length by a cutter 10 is provided in a protruding manner.

Note that 12 is a power supply section including a power supply device and the like.

There is a strong demand for smaller size and lighter weight in recording devices such as facsimile machines, and the above-mentioned recording devices have document storage tray 9 and recording sheet storage tray 11 that protrude from both sides of facsimile machine body 1. Therefore, even if the main body of the device is made smaller, the actual installation space cannot be reduced much due to these protruding trays.As a solution to this problem, the trays are grouped together on one side of the main body of the device. , it is also possible to omit the space for one tray.

However, if you concentrate 1~ray on one side of the device body,
The drive systems for the information reading and transmitting system and the information receiving and recording system will also be concentrated, which will impede space efficiency inside the device and complicate the drive system, which may lead to a decrease in reliability.
Furthermore, there is a possibility that it will become a factor to increase the cost to 1.

Furthermore, in the conventional recording apparatus described above, the recording sheets 1 to 1 on which images have been formed are discharged from the apparatus with their recording surfaces facing up and are stacked one after another. Therefore, when creating a record of a multi-page document, the image-formed recording sheets 1 to 1 discharged from the device are stacked one after another, with the first page facing down and the second and subsequent pages stacked one on top of the other. The order will be the reverse of the original order.

For this reason, after the recording operation is completed, the recording sheets on which images have been formed must be rearranged from one page to the next, a so-called page alignment operation, which is a very time-consuming task.

Furthermore, sheets wound into rolls, such as recording sheets used in facsimile machines, etc., have the disadvantage that they are difficult to store in an orderly manner on a straight tray surface as in the past because they are rolled tightly. Recently, in line with the miniaturization of the equipment itself, there has been a trend to reduce the outer diameter of the roll as much as possible without changing the length of sea 1-, and one way to do this is to make the core diameter smaller. It is being As a result, the curling tendency becomes more pronounced, and it is desired to develop a method for storing recording sheets after image formation to cope with this tendency.

Therefore, in order to solve these problems, the applicant has
He invented and proposed a recording sheet storage tray as shown in the figure. (Patent Application No. 134.175 of 1982).

In the figure, the recording sheet storage tray 13 is provided in the vicinity of the recording sheet 1 to the lower part of the ejection port of the facsimile machine 1, and is a tray that comes into contact with the recording sheet 7 on which an image has been formed and guides it downward. 1, an outer tray 14 as a member, and a recording sheet storage space 1 facing the outer tray 14.
The inner tray 15 serves as a second guide member for forming the inner tray 6.

The lower end of the inner tray 15 is connected to the lower end of the outer tray 14 by a pin 17, and the outer tray 14 is rotatably supported around the bin 17. The outer tray 14 is locked to the apparatus main body 1 by a click mechanism shown, and is normally held in a closed position.

The outer tray 14 is provided with a plurality of rifts 18, and is configured to reduce contact resistance with the leading edge of the recording sheet 7 and smoothly guide it into the storage space 16 of the recording sheet storage tray 13.

Further, the outer tray 14 and the inner trays 1 to 15 form a 7-shaped gripping portion 19 for gripping the leading edge of the recording sheet 7.

Furthermore, when the outer tray 14 is closed, the outer tray 14
An opening 20 is provided at the upper end so that when the long recording sheet 7 is stored, the rear end of the recording sheet 7 can be turned around in a loop and discharged outward.

However, there is a limit to the force with which the 7-shaped gripping portion 19 can grip the leading edge of the recording sheet 7, making it unsuitable for storing a large number of recording sheets. Furthermore, when receiving extremely long recording sheets, there was also the problem that the sheets could not be removed from the tray.

Therefore, in order to solve these problems, the applicant has proposed the fourth
He invented and proposed a recording sheet shrink tray as shown in the figure. () The means includes a first guide member 14 that guides the leading edge of the recording sheet on which an image has been recorded by the recording section downward, and a second guide member 14 that forms a recording sheet storage space opposite to the first guide member. a guide member 15, an opening portion 20 at the upper end of the first guide member that allows the rear end of the recording sheet to be reversed, and a driven ejection roller 28 provided on the recording sheet usage side of the recording apparatus. A pair of utilization rollers consisting of a pinch roller 29 provided opposite the discharge roller, a rotating clip roller 33 provided in the storage space, and a rotating clip roller 33 provided in the storage space to control the leading edge of the recording sheet fed downward. It is characterized by the provision of a press plate 30 for gripping.

As a result, when the recording sheets discharged from the image forming section of the recording apparatus are stored in the recording sheet storages 1 to 1, the recording sheets on which images have been formed are fed out from the pair of discharge rollers 28 and 29 of the discharge section. 1 guide member 14
The recording sheet comes into contact with the recording sheet, is guided downward, and is fed into the recording sheet storage space.

The leading edge of the recording sheet that has entered the sheet storage space is captured by the clip roller 33, sent downward and gripped by the gripping section, and then comes into contact with the bottom of the tray to stop its forward movement.

When image recording continues, the recording sheet is still ejected, and is then ejected from the main body of the apparatus in a loop by the rotation of the ejection roller pair.

When the image recording is completed and the recording sheet 1~ is cut by the cutter, the rear end of the recording sheet 1~ hangs down to the outside of the main body of the apparatus due to its own weight. At this time, since the leading end of the recording sheet is gripped by the gripping section, the recording sheet will not fall out of the main body of the apparatus.

[Problems to be Solved by the Invention] However, the gap between the outer tray 14 and the clip roller 33 or between the outer tray 14 and the press plate 30 for gripping the recording sheet 7 is a certain value, and naturally the recording sheets 1 to 1 to be gripped have a certain value. The number of 7s was limited. Therefore, it is necessary to widen this gap in proportion to the number of recording sheets 7 stored.

As an example of this, it is conceivable to widen the gap by rotating the outer tray 14 around the connecting pin 17 at the lower end of the inner tray 15 and the outer tray 14, as shown in FIG. Or outside tray 1
If the number 4 is tilted too much, the record sheets 1 to 7 of the storage method will easily fall off, resulting in a decrease in the number of sheets stored.

Alternatively, as shown in Fig. 6, it may be possible to move the clip roller 33 backwards with respect to the outer latch 14 to secure a gap. 33, the mechanism becomes complicated. Moreover, unless the clip roller 33 is moved parallel to the outside 1 to 14 with high accuracy, the clip roller 33 and the recording sheet 7
It is often the case that the recording sheet 7 is skewed, causing a paper jam.

[Means for Solving the Problems] Therefore, the present invention maintains the inclination of the outer tray forming the 7-shaped sheet gripping part at an optimal angle, and stores the recording sheet in the gap between the clip roller or the pressing plate and the outer tray. The wide size is intended to accommodate a large amount of recording sheets in proportion to the number of sheets.

[Example] An example of the present invention will be described below with reference to the drawings. In addition, in the figure, the same numbers are used for parts that are the same as in the conventional example.
I will explain.

FIG. 1 is an explanatory diagram of the case where the present invention is applied to a facsimile machine.

In the figure, a recording sheet 7 fed out from a recording sheet roll 5 is introduced into a recording section constituted by a platen roller 6 and a recording head 8. The recording sheet 7 on which an image has been formed in the recording section is guided to a cutter 10.

The cutter 10 includes a guide blade 21 and a rotary blade 22.

The biasing blade 21 is biased in the direction of the rotary blade 22 by a biasing spring 23. The rotary blade 22 has a predetermined inclination with respect to the blade surface of the biasing blade 21, and is rotatably provided in the device main body l with a shaft 24 as a fulcrum. Further, the rotary blade 22 is driven by a drive device shown in the figure in synchronization with the recording operation of the recording section.

A blade cover 25 is provided on the side of the rotary blade 22 through which the recording sheet 7 passes.

The blade cover 25 is provided so as to be inclined at a predetermined angle relative to the rotary blade 22 or the biasing blade 21, so that even a human hand cannot enter the gap formed by the blade surfaces of the two blades. covers that gap.

Furthermore, the blade cover 25 has a guide cover 26 or a slot 1-.
It is attached by means such as welding.

The cover 26 is provided over the entire length of the blade cover 25, and is open in the front and rear directions with respect to the direction in which the recording sheet 7 passes. Further, the recording section side of the guide cover 26 is bent so that the recording sheet 7 can be easily introduced.

The recording substrate 27 is configured to guide the leading edge of the recording sheet 7 toward a discharge roller 28 forming a pair of discharge rollers and a pinch roller 29 which is in pressure contact with and follows the discharge roller 28 .

The discharge roller 28 is driven at the same circumferential speed as the platen roller 6 by a drive device shown in the figure.

An outer tray 14 serves as a first guide member, and is provided with a plurality of ridges 18. Furthermore, the outer tray 14
storage space 1 with inner tray 15 as a guide member.
6 is formed.

In the storage space 16, a press plate 30 for gripping the leading edge of the recording sheet 7 is rotatably supported on a shaft 31 provided on the inner tray 15 side, and a press spring 32 moves the press plate 30 to the outer tray 14.
The recording sheet 7 is biased toward the side so that the recording sheet 7 can be gripped by the surface of the suppression plate 30 and the rift 18.

In order to reduce the resistance when the tips of the recording sheets 1 to 7 enter, the surface of the suppression plate 30 is coated with a resin or the like having a low coefficient of friction.

Further, a clip roller 33 is provided in the storage space 16, and this clip roller 33 rotates about a shaft 31 by receiving the driving force of the discharge roller 28 through a clip heald 34.

The surface of the clip roller 33 is knurled so that it can reliably capture the surface of the recording sheet 7. A gap is provided between the clip roller 33 and the rift 18.

35 is the bottom of the storage space 16.

Next, the operation of the recording apparatus configured as above will be explained.

The recording sheet roll 5 wound into a roll is rewound from its leading end and is supplied between a platen roller 6 and a recording head 8 . An image is formed on the surface of the recording sheet 7 by a recording head 8, and the recording sheet 7 is transported as the platen roller 6 rotates.

The leading edge of the recording sheet passes between the biasing blade 21 and the rotary blade 22 that constitute the cutter 10, passes between the blade cover 25 and the chi 1-cover 26, and comes into contact with the recording substrate 27. The leading end of the recording sheet is guided by the recording substrate 27 to a pair of discharge rollers, and is held between a discharge roller 28 and a pinch roller 29 and discharged.

The leading edge of the recording sheet 7 discharged from the pair of discharge rollers 28 and 29 enters the lower part of the storage space 16. Thereafter, the leading end of the recording sheet 7 is held by the pressing plate 30 and the rift 18. When the number of recording sheets 7 to be gripped is small, the suppression plate 30. The recording sheets 7 are held by the clip rollers 33 and the lift 18 when the recording sheets 7 are gripped by the clip rollers 33 or when the number of stacked sheets increases.

When the leading edge of the recording sheet 7 comes into contact with the bottom 35, the recording sheet 7 stops advancing.

When the leading edge of the recording sheet 7 comes into contact with the bottom 35 and stops entering the storage space 16, if the recording section continues to form an image on the recording sheet 7, the recording sheet 7 is still in the ejection port. It continues to be ejected from La vs. 28.29. In such a case, the recording sheet 7 is discharged in a loop form to the outside of the apparatus main body l through an opening 20 formed at the upper end of the outer tray 14.

After the image formation is completed and the recording sheet 7 is cut by the cutter 10, the discharge roller pair continues to rotate and the recording sheet is cut.
The rear end of the paper 7 is discharged from a pair of discharge rollers 28 and 29.

Due to the weight of the portion discharged in a loop, the recording sheet 7 is held at the leading edge by the suppression plate and placed on the outer tray 14.
The subsequent recording sheets 7 also hang down outside the outer tray 14, thereby reducing the storage space i6.
layered inside.

Furthermore, in proportion to the amount of recording sheets 7 to be stacked, the outer one head 14 sequentially moves from the position indicated by the two-dot chain line to the position indicated by the solid line in the figure, thereby widening the gap between the clip roller 33 and the rift 18. Provide storage space. When the outer tray 14 moves, the inner tray 1 does not receive the force of the tension spring 41.42 by the link lever 39.40 rotatably supported on the fulcrum 44.
5. This is done almost parallel to 5.

[Effects of the Invention] The sheet material storage tray of the present invention described in detail above (in the inner and outer 1-rays constituting the storage tray) moves the outer 1-ray parallel to the inner tray to increase the storage space for recording sheets. , which made it possible to store a large amount of sheets.

Further, as the outer tray moves, the pressing force of the outer tray against the recording sheet is increased by the springs, which is effective in preventing the recording sheet from slipping off.

Furthermore, the sheet material storage tray of the present invention also has the following effects as a basic feature.

(1) The recording paper storage tray protrudes from the main body of the apparatus as in conventional recording apparatuses, which has the effect of reducing the size of the entire apparatus and requiring less installation space.

Furthermore, in the recording sheet storage tray of the present invention, the recording sheets 1 to 1 on which images have been formed are ejected with their recording surfaces facing upwards, and during subsequent stacking, a second sheet is placed behind the first sheet. Since the first and subsequent sheets are stacked one after the other, the recording sheets taken out from the recording sheet storage tray are in the order in which they were recorded, and there is also the advantage that there is no need for post-work such as page alignment.

Furthermore, by providing a pressing plate and a clip roller in the recording sheet storage tray, it is possible to prevent recording sheets from slipping out of the recording sheet storage tray depending on the number of recording sheets stacked. It also has effects.
