Abstract

PURPOSE:To make the paging order of paper discharged correctly arrangeable at the time of automatic printing of continuous documents in bulk by forming a paper discharge tray into a movable system, and making a paper discharge direction free of changing over to both nearby and remote sides to an operator. CONSTITUTION:When a paper discharge tray 10 is tilted to the side remote to an operator, paper 4 is discharged in a state of being upped of its face. Consequently, printing can be done as making certain of a printing state. In addition, when the tray 10 is tilted to the nearby side of the operator, the paper 4 is discharged in its face down state. Accordingly, the paper 4 is stacked aright at paging order.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording device, and particularly to a recording device such as a typewriter that is equipped with a cut sheet feeder that can automatically feed cut sheets to a recording position.

(Prior Art) In general, one method of supplying printing paper to a recording device such as a typewriter is to stack a large number of sheets of paper cut to a certain size in a layer, and then move the paper as the typewriter moves. Cut sheet feeders are widely used, which have a structure that feeds sheets one sheet at a time to a platen, which is a recording position, in synchronization with the recording position.

In a conventional cut sheet feeder of this kind, the sheets of paper after printing are sent from a platen by a paper ejection roller, ejected to a paper ejection tray, and stacked.

When printing consecutive sentences on multiple pages and outputting them to the output tray, for example, if you output them face-up, after printing the first page, the second page, the third page, etc.
The second page is printed on top of the first page, and the third page is on top of that, which is the reverse of the order in which documents are normally used, so at the end, change the order of all documents. There is a need. In contrast to such conventional methods, by configuring a path in which printed paper is ejected from the platen and then ejected to the operator side, the paper is stacked face-down on the printing area and used as a normal document. There is also a conventional example in which the above-mentioned drawbacks are improved by adopting the above order.

[Problem to be solved by the invention]

However, when using a recording device as a typewriter, it is essential that the printed characters be immediately visible to the operator, but in the latter conventional example mentioned above, due to the layout, Your view is blocked by the paper output tray or the paper after printing, so you cannot see the print immediately after it is printed. In this respect, the former conventional example can be said to be superior because it does not obstruct the field of view.

Therefore, the former is inconvenient for automatic printing of large volumes of continuous text, but is convenient for printing without checking the printing status of a single sheet, while the latter is inconvenient for automatic printing of large volumes of continuous text. Although this is convenient, it is impossible to print while checking the printing condition of a single sheet. In that case, the cut sheet feeder must be removed from the recording apparatus each time, which is very inconvenient.

In this way, both conventional examples have long and short lengths and are incomplete.

In view of such conventional problems, it is an object of the present invention to enable ejection in a face-up and face-down state with a simple configuration, and to ensure that pages are stacked correctly when printing a large volume of continuous text, and that a single sheet is not printed. It is an object of the present invention to provide a recording device equipped with an inexpensive cut sheet feeder that can print while checking the printing state during printing.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a cut sheet feeder that can automatically feed cut sheets to a recording position, and a means for discharging cut sheets from the recording position to a paper output tray. The recording apparatus is characterized in that the paper ejection tray is configured so that the inclination of the paper ejection tray can be switched in two directions, a side closer to the operator and a side farther away from the operator, with the vertical plane as the boundary.

[For production]

According to the present invention, the paper ejection tray is configured so that its inclination can be switched in two directions, a side closer to the operator and a side farther from the operator, with the vertical plane as the boundary.

Therefore, when the paper ejection tray is tilted away from the operator, the paper is ejected in the form of face squares and bulges, so that printing can be performed while checking the printing state.

Furthermore, when the paper ejection tray is tilted toward the side closer to the operator, the sheets are ejected face down, so that they are correctly stacked in page order.

(Example) Embodiments of the present invention will be described below with reference to the accompanying drawings.

First, FIG. 1 is an overall perspective view of an electronic typewriter equipped with a cut sheet feeder showing an embodiment of the present invention.

At the top of the electronic typewriter 1, there is a cut sheet feeder 2 or a platen 3 of the electronic typewriter 1.
The electronic typewriter 1 is connected to the electronic typewriter 1 so that the sheets are sequentially fed from a bundle of cut sheets 4 to the printing section of the electronic typewriter 1. After printing on the sheets, they are ejected from the electronic typewriter 1 and stacked on the front of the cut sheet feeder 2 again.

FIG. 2 is a sectional view of a main part showing the structure of the present invention, and is a detailed view of the second part of the cut sheet feeder shown in FIG. A paper feed roller 5 is in pressure contact with the eastern part of the paper 4, and the paper 4 is moved from the stacker 7 in the direction of the arrow 6 by the rotational force of a motor (not shown) installed inside the side plate 14 and a reduction gear train. The sheets are supplied one by one to the platen 3 of the electronic typewriter 1. With the paper 4 wrapped around the platen 3, printing is sequentially performed by a printing mechanism (not shown) as is well known, and the paper 4 after printing is transferred to a pair of paper ejection rollers 8 located above the platen 3. The paper is lifted up at 9 and ejected to the first and second paper ejection trays 10 and 11, and the printing sequence for one sheet of paper is completed.

Here, the paper discharge roller 8 is driven by the above-mentioned motor via a reduction gear train (not shown) in the same way as the paper feed roller 5. A plurality of paper ejection rollers 8 are integrally provided on a paper ejection roller shaft 12 , and transmission torque from the paper ejection roller shaft 12 is directly transmitted to the paper ejection roller 8 .

The paper discharge roller 9 is supported by a paper discharge roller glaze 15, and the paper discharge roller shafts 12 and 15 are supported by bearing portions of both side plates 13 and 14 of the cut sheet feeder 2.

The second paper discharge tray 11 has a substantially L-shaped cross section, and cylindrical portions 118 formed at both ends are rotatably fitted onto the paper discharge roller shaft 12. And cut sheet feeder 2
It is kept in the state shown in FIG. 2 by contacting an abutting plate 16 fixedly attached to the abutment plate 16 .

Next, the coupling relationship between the second paper discharge tray 11 and the first paper discharge tray 10 will be explained based on FIG. 3.

A shaft-shaped boss II is provided at the upper both ends of the second paper output tray 11.
A protruding portion B is rotatably connected to a cylindrical bearing portion 10A formed at both ends of the lower portion of the first paper discharge tray 1O and having slits. V-shaped groove 11C in Hoss IIB
are provided at two locations spaced apart by approximately 90' 11. On the other hand, an elastic claw portion 10B is formed on the bearing portion 108, and the claw portion 10B and the V-shaped groove 11C engage with each other to prevent rotation. The first and second paper output trays 10 and 11
is fixed. Since there are two V-shaped grooves 11G, when the first output tray 10 is rotated relatively counterclockwise around the boss IIB by applying an external force, the claw portion 10B comes out of the V-shaped groove 11C and rotates. , after rotating about 90 degrees, the claw portion 10B again engages with another V-shaped groove 11C and is fixed.

In other words, it has a structure that can have two postures: the state shown in FIGS. 2 and 3, and the state at an angle of approximately 90°.

Further, the second paper ejection tray 11 includes an open portion LID in which the ejection roller 8 is accommodated, a regulation plate 11E located below the open portion LLD in the state shown in the second diagram, and a regulation plate 11E located below the ejection roller 9.
A notch IIF is formed having a width approximately equal to the width of the notch IIF.

As described above, as shown in the first and second figures, the first and second paper output trays IO and II are tilted and positioned in the direction away from the operator (the first and second paper output trays
position) allows you to operate the printer while checking the print.

Next, the operation of tilting and positioning the paper discharge tray closer to the operator will be explained using FIG.

As described above, the first and second paper output trays lO and 1
1 is rotatably supported around a paper ejection roller shaft 12 as a center of rotation. Paper ejection roller in the corner! j'tb 15, and the first paper discharge tray 10 can be rotated about 90 degrees in the direction of the arrow 18 about the boss IIB and fixed. At this time, the second paper ejection tray 11 tries to rotate around the paper ejection roller shaft 12 in the direction of the arrow 18, but this is caused by the side plate 13.
14 is restricted by a stopper (not shown) formed inside. This series of operations completes the movement of the paper discharge tray to the second position. Of course, it is also possible to return it to the first position by performing the reverse operation.

The behavior of the paper in the second position will be explained using the sectional view of the mechanism in FIG.

The process from when the paper is fed from the paper feed roller 5 to the platen 3 and after printing is sent from the platen 3 to the paper ejection roller 8 is exactly the same as when the paper ejection tray is in the first position (see Figure 2). , the paper 4 pulled upward by the paper discharge rollers 8 and 9 passes through the second paper discharge tray opening section 110,
Regulation plate 11 integrally formed on second paper ejection tray 11
The ejection path of the paper 4 is changed by E, and the paper 4 is sent in the direction of the arrow 19. Then, the paper sheets are stacked face down on the back surface of the first paper discharge tray IO.

An overall perspective view in this state is shown in FIG.

Further, FIG. 7 shows how the sheets are stacked after printing in this state. The numbers printed in the order of NO, 1, 2, and 3 are stacked face down in the order of NO, 1, and 2.3.

As shown in Figure 5 above, by positioning the output tray at an angle closer to the operator (the second position of the output tray), pages can be stacked correctly when automatically printing large-volume continuous documents. It has become accustomed to the state.

FIG. 8 shows how the sheets are stacked after printing when the paper ejection tray is in the first position. The number printed in the order of NO, l, 2.3 is displayed face-up.
They pile up in the order of 3.

In the above-mentioned embodiment, the paper ejection roller shaft was also used as the rotation center for changing the inclination angle of the paper ejection tray, but it is possible to use another independent rotation shaft. Not even.

(Effects of the Invention) As is clear from the above description, according to the present invention, the paper ejection tray is made movable so that the paper ejection direction can be easily switched both to the side closer to the operator and the side farther away from the operator. The cut sheet has a simple configuration that allows the pages of ejected paper to be stacked correctly when automatically printing large-volume continuous documents, and also allows printing while checking special printing on a single sheet. A recording device equipped with a feeder can be obtained at low cost.
