Abstract

PURPOSE:To make more numerous recording sheets possible to be loaded and prevent the recording sheets from slipping down, by making the first guide member possible to make turning movement position higher than a protuberance part provided on the second guide member. CONSTITUTION:An increase in a number of loaded recording sheets 7 leaves no gap between a grip roller 33 and a rib 18 and the recording sheets 7 are held by the grip roller 33 and the rib 18. In this case, an outside tray 14, rotating centering around a fulcrum shaft 39, widens the gap and also, strength a spring 42 which is hung between an inside tray 15 and the outside tray 14 in proportion to the number of loaded recording sheets 7. Thus, the gap between the rib 18 or the like on the outside tray 14 and the outside tray 14 for forming a store space for the recording sheets 7 is widened in proportion to the number of loaded sheets and more numerous recording sheets 7 can be loaded. Also, the pushing pressure of the outside tray 14 to the recording sheets 7 is increased and the recording sheets already loaded can be prevented from slipping down.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sheet material storage tray, and more specifically, the present invention relates to a sheet material storage tray that is installed as a paper ejection section of a recording device such as a facsimile or a copying machine, and is ejected from an image forming section. The present invention relates to a sheet material storage tray that stores recording sheets on which images have been formed.

[Conventional technology]

2. Description of the Related Art A recording sheet storage tray for storing 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 the Noah Axim apparatus equipped with such a recording sheet storage tray.

In the figure, ■ is the main body of the facsimile machine, and information on the document 3 sent on the document table 3 is transferred to the mirrors 4''a and 4b.
an information reading and transmitting system that reads the information by a reading unit 4 configured to convert it into an electric signal by a photoelectric conversion element 4c such as a CCD, and transmits the information; and a recording sheet 7 fed out from a recording paper roll 5 by a platen roller 6. It is equipped with an information receiving and recording system having a recording head 8 for recording received information thereon.

In the figure, a document storage tray 9 is provided on the left side of the facsimile device main body 1 to store the document 3 sent out from the document table 2, and a document storage tray 9 is provided on the right side of the facsimile device main body 1.
A recording sort storage tray 11 is provided protrudingly for storing the image-formed recording sheets 7 on which images are recorded by the recording head 8 and cut into predetermined lengths by the cutter 10. It includes a power supply section.

There is a strong demand for smaller size and lighter weight in recording devices such as facsimile machines, but in the above-mentioned recording devices, the document storage tray 9 and the recorded note storage tray 11 protrude from both sides of the facsimile device main body 1. Therefore, even if the main body 1 of the apparatus is downsized, the actual installation space cannot be reduced very 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 apparatus.
It might be possible to omit the space for one tray, but if the trays are concentrated on one side of the device, the drive systems for the information reading and transmitting system and the information receiving and recording system will also be concentrated, and the device This impedes internal space efficiency and complicates the drive system, which may lead to a decrease in reliability and may also be a factor in increasing costs.

Furthermore, in the conventional recording apparatus described above, the recording sheets on which images have been formed are discharged from the apparatus with the recording surface facing upward and are stacked one after another. Therefore, when creating records of multiple pages of originals, the recording sheets with images formed on them that are ejected from the device are stacked one after the other, with the first page facing down and the second and subsequent pages on top of each other. and in the opposite order.

For this reason, after the recording operation is completed, it is necessary to rearrange the recording sheets on which images have been formed starting from the first page, a so-called page alignment operation, which is a very time-consuming operation. The disadvantage is that rolled sheets, such as recording sheets, tend to curl tightly, making it difficult to store them in an orderly manner on a straight tray surface like in the past. /J on main unit
) There is a tendency to reduce the outer diameter of the roll as much as possible without changing the length of the roll, and one method for achieving this goal is to reduce the diameter of the core. As a result, it is desired to develop a storage method for recording notebooks after image formation, which becomes more noticeable when rolled up.

Therefore, in order to solve these problems, the applicant has proposed the third
He invented and proposed a recording sheet storage tray as shown in the figure (Japanese Patent Application No. 1341/1975).

In the figure, the recording note storage tray 13 is provided near the lower side of the recording sheet ejection port of the facsimile machine 1, and the recording sheet 7 on which an image has been formed comes into contact with the recording notebook storage tray 13, which guides it downward. It is composed of an outer tray 14 as a guide member and an inner tray 15 as a second guide member for forming a recording sheet storage space 16 opposite to the outer tray 14.

The lower end of the outer tray 14 is connected to the lower end of the inner tray 15 by a pin 17, and the outer tray 14 is rotatably supported around the pin 17. Outer tray 1
4 is locked to the device main body 1 by a click mechanism (not shown), and is normally held in the closed position.

The outer tray 14 is provided with a plurality of lips 18, and is configured to reduce contact resistance with the tip of the recording/-door and smoothly guide the recording/sort storage tray 13 to the storage space 16.

Further, the outer tray 14 and the inner tray 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 part 20 is provided at the upper end so that when the long recording sheets 7-1 and 7 are stored, the rear end of the recording sheet 7 can be reversed in a loop shape and discharged to the outside.

Furthermore, as shown in FIG. 4, in order to make the gripping part 19 more securely grip the recording sheet 7, the four inventors created a
a second guide member that faces the first guide member and forms a recording sort storage space;
an opening portion at the upper end of the guide member for allowing the trailing edge of the recording note to be reversed; a driven discharge roller provided on the side of the recording sheet discharge portion of the recording device; and a pinch provided opposite to the discharge roller. a recording sorting storage tray comprising: a pair of discharge rollers consisting of a roller; a rotating grip roller provided in the storage space; and a suppression plate provided in the storage space to grip the leading edge of a recording sheet fed downward. (Japanese Patent Application No. 62-46673).

[Problems to be Solved by the Invention] However, with the above-mentioned conventional configuration, there is a problem in that the storage capacity of the sheet 1 and the material tends to decrease as the number of sheet materials to be stored further increases. Ta.

[Means and effects for solving the problems] In the present invention,
As the operation is repeated and the number of stored notebooks increases, the first guide member rotates about a position higher than the suppressing means such as the grip roller as a fulcrum, and the grip roller and the first guide member rotate as the number of stored notebooks increases. By expanding the storage space between the kite member and the kite member, more records can be stored.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In the drawings, parts that are the same as those in the conventional example will be described using the same numbers.

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

The recording sheet 7 fed out from the recording sheet roll 5 is
It 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 0.

The cutter 0 is composed of a biasing 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 1 about a shaft 24 as a fulcrum. Further, the rotary blade 22 is driven by a drive device (not shown) 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 that the rotary blade 22 is inclined at a predetermined angle with respect to the biasing blade 21, so that, for example, a human hand cannot enter into the gap formed by the blade surfaces of both blades. It covers that gap.

Further, a guide cover 26 is attached to the blade cover 25 by means such as spot welding. The kite 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 passing direction of the recording sheet 1-7. 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 ribbed roller 6 by a drive device (not shown).

Reference numeral 14 designates an outer tray as a first guide member, which is provided with a plurality of ribs 18. Furthermore, the outer tray 14
storage space 1 with inner tray 15 as a guide member.
6 is formed.

This outer tray 14 is rotatably mounted around a fulcrum shaft 39.

When the outer tray 14 rotates from the position 43 indicated by the two-dot chain line to the position 44 indicated by the solid line in FIG. The pin 42 is hung between the bin 41 attached to the inner tray 15 and the pin 40 attached to the outer tray 14, and has the role of always urging the outer tray 14 against the inner tray 15. 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. 14 side so that the recording sheet 7 can be gripped by the surface of the suppression plate 30 and the ribs 18.

In order to reduce the resistance when the leading edge of the recording sheet 7 enters, the surface of the pressing plate 30 is coated with a resin or the like having a low coefficient of friction.

Furthermore, a grip roller 033 is provided in the storage space 16, and this grip roller 33 rotates around a shaft 31 by receiving the driving force of the discharge roller 28 through the grip belt 34.

The surface of the grip roller 330 is knurled so that it can reliably grip the surface of the recording sheet 7. The grip rollers 33 are configured to have a gap between them and the ribs 18.

35 is the bottom of the storage space 16. 36 is a rubber piece that applies frictional force to the notebook.

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

Recording sheet rolled into a roll 5 (d.

It is rewound from its tip and supplied between the platen roller 6 and the recording head 8. The recording sheet 7 has an image formed on its surface by the recording head 8, and is transported as the platen opening 6 rotates.
It passes between the biasing blade 21 and the rotary blade 22 that constitute the blade cover 25 and the guide 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 row 228 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 edge of the recording sheet 7 is gripped by the pressing plate 30 and the rib 18. If the number of recording sheets 7 to be gripped is small, the leading edge of the recording sheet 7 is gripped by the pressing plate 30, but if the number of loaded sheets increases, the grip roller 33 The recording sheet 7 is held by the grip rollers 33 and the ribs 18 so that there is no gap between the grip rollers 33 and the ribs 18.

At this time, the outer tray 14 rotates around the fulcrum shaft 39 and gradually widens the gap. Further, the spring 42 applied between the inner tray 15 and the outer tray 140 is strengthened in proportion to the number of recording sorts 7 loaded.

Further, as the outer tray 14 rotates, its upper end moves toward the inner tray 15, so that the recording sheets 7 serving as the stacking source stand up substantially vertically. Therefore, it becomes even more difficult to fall.

When the leading edge of the recording sheet 7 introduced in this manner comes into contact with the bottom portion 35, it stops advancing.

When the leading edge of the recording sheet 7 comes into contact with the bottom part 35 and stops entering the storage space 16, if the image formation on the recording sheet 7 continues in the recording section, the recording sheet 7 is still in contact with the ejection roller. It continues to be discharged from 28.29.

In such a case, the recording sheet 7 is discharged in a loop form to the outside of the apparatus main body 1 through an opening 20 formed at the upper end of the outer tray 14A.

After the image formation is completed and the recording sheet 7 is cut by the cutter 10, the pair of discharge rollers continues to rotate and the rear end of the recording sheet 7 is discharged from the pair of discharge rollers 28 and 29. Due to the weight of the portion discharged in a loop, the recording sheet 7 hangs down to the outside of the outer tray 14 while its leading end is held by the suppression plate, and subsequent recording sheets 7 are also dropped to the outside of the outer tray 14 in the same manner. By hanging down, they are stacked in the storage space 16.

Furthermore, 36 is a slip prevention material such as a rubber piece provided on the upper part of the outer tray 14, and when the recording sheets 7 are stacked in the storage space 16, the recording sheet 7 of the first month slides up and the recording sheet 7 is placed on top of the outer tray 14. This prevents the paper from falling outside the storage tray.

38 is an upper case in which the recording head 8 and the recording board 27 are mounted.
and a pinch roller 29 are provided. Upper case 3
Platen roller 6, cutter 10 by opening 8.
Since the discharge roller 28 is exposed, it is configured to be advantageous for replacing the recording sheet roll 5.

The recording sheet storage tray of the present invention also has the following basic features: It does not protrude from the main body of the apparatus unlike conventional recording apparatuses, and therefore the entire apparatus can be made smaller and requires less installation space. It also has the effect of reducing

Furthermore, in the recording sheet storage tray of the present invention, the recording sheet on which the image has been formed is ejected with the recording surface facing up,
During subsequent stacking, the second and subsequent sheets are stacked after the first sheet, so the recording sheets taken out from the recording sheet storage tray are in the order in which they were recorded. Another advantage is that post-work such as page alignment is not required.

Furthermore, by providing a pressure plate and a grip roller inside the recording sort storage tray, it is possible to prevent the recording sort from slipping out of the recording sheet storage tray regardless of the number of stacked recording sheets. have an effect.

In addition, although the grip rollers and ribs are used as elements to form the storage space in the embodiment, storage can also be achieved by making the inner tray partially convex instead of the rollers, or by making the surfaces of the outer tray directly face each other instead of the ribs. Space is formed and has a similar effect.

〔Effect of the invention〕

In the sheet material storage tray of the present invention described in detail above, the outer tray is rotated about a position higher than the pressing means such as the grip rollers as a fulcrum, and the pressing means (grip rollers) forming the recording paper storage space are moved on the outer tray. The gap between the ribs, etc. is widened in proportion to the number of sheets loaded, making it possible to load more recording sheets.

Furthermore, by applying a spring between the inner tray and the outer tray, the pressing force against the recording sheets on the outer tray is increased in proportion to the number of sheets loaded, thereby having the effect of completely preventing the loaded sheets from slipping down.

Furthermore, as the outer tray rotates, the upper end of the outer tray moves toward the inner tray, and by raising the height of the loaded recording sheets, the tip of the recording notebook that is being fed smoothly fits into the V-shaped storage space. It has the effect of making it easier to enter.
