Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] A medium storage device is provided with a reversing mechanism for a recording device, and the receiving tray of the medium storage device has a mounting portion for engaging with the recording device, and a reversing mechanism. A drive connector is provided,
The receiving tray is configured to be removably attached to the recording device, and in the event of a paper jam, the receiving tray is removed from the recording device to facilitate removal of jammed paper.Furthermore, a mechanism is provided to repeatedly move the receiving tray horizontally. Trays were moved for each document to enable separate stacking.

[Industrial application field]

The present invention relates to a medium storage device for a recording device, and uses an impeller-type reversing mechanism to reduce the size of the device that reverses and stores the recording medium, and also to facilitate removal of jammed paper when paper is jammed. , relates to a medium storage device that can be easily attached to and removed from a recording device.

In general, a storage device (stacker) that stores recording media ejected from a recording device such as a printer or a copier is a normal rotating storage device that stores the recording media ejected from the recording device as is on a tray. It is a mechanism. 4(a) and 4(b) show the trays of the forward rotation mechanism, and trays 1a and lb are fitted with holes 3 or bins 4 so as to be attached to the paper output portion of the recording device 2.
In Fig. 4(a), the protrusion 5 of the tray 1a, the fourth
In the figure (b), the hook 6 of the tray 1b is ajar.

These are put into the hole 3 or bottle 4 of the ejector, or hooked and fixed. Then, the A point of the tray la hits the four points of the recording device 2, and the tray is stabilized by its own weight. The same applies to the cross-tray 1b. Note that 7 indicates a discharge roller.

As described above, it is very easy to attach and detach the trays 1a and 1b to and from the recording apparatus 2, and in the event of a paper jam, the trays Ia and lb can be removed and the jammed paper can be easily removed. However, there is a drawback that the recording medium ejected from the recording device 2 is stored on the tray in reverse order.

Therefore, there is a need for a media storage device that stores media on a tray in the correct page order.

[Conventional technology]

A conventional medium storage device equipped with a reversing mechanism includes, for example, a fifth
There is something like the one shown in the figure. Media storage device 8 in the figure
is connected to the recording device 2, the recording device 2 has a paper cassette 9, and the paper 10 is transferred from the paper cassette 9 to the recording device 2.
The toner image on the photosensitive drum 12 is transferred to the paper 10 and fixed by the fixing section 13, and then ejected by the ejection roller 7 and stored in the medium storage device 8. The medium storage device 8 consists of a reversing mechanism 16 consisting of many rollers 14 and guides 15, and a pedestal 17, and the sheets 10 are reversely transported and arranged and stored on the pedestal 17 in page order. Note that there is a motor (not shown) that drives the many rollers 14, and the power to this motor is supplied from the power supply of the recording apparatus 2.

[Problem that the invention seeks to solve]

The reversing mechanism 16 of the conventional medium storage device 8 shown in FIG. 5 requires many rollers 14 to reverse the ejected paper 10, which makes the structure complicated and requires a large amount of space. Met.

In addition, since the reversing mechanism 16 is directly attached to the recording device 2 or is a part of the main body structure, if a paper jam occurs in the ejection section of the recording device 2, the reversing mechanism 16
It was difficult and troublesome to remove the paper and remove the jammed paper. If the problem persists, a specialist maintenance person is called.

[Means for solving problems]

FIG. 11 is a diagram explaining the present invention in detail, (A) is a sectional view showing the state in which the tray of the present invention is attached to a recording device, and (B) is a state in which the tray of the present invention is repeatedly moved. FIG.

In FIG. 1(A), reference numeral 18 is a receiving tray, and on the side of the receiving tray 18 loaded into the discharge port P of the recording device 2, there is a conventional tray la shown in FIGS. 4(A) and 4(B). (
or lb), similar protrusion 5 (or hook 6)
), and is further provided with a connector 20 connected to a motor that drives an impeller 19 of a reversing mechanism, which will be described later. On the other hand, on the discharge port P side of the recording device 2, as shown in FIGS. A connector 21 connected to a matching device power supply is provided.

Further, on the tray top 18, there is an impeller-type reversing mechanism 22 shown in FIG. 1(C). This has already been proposed as a miniaturized reversing mechanism. The reversing mechanism 22 has a pair (one or more) of impellers 19 arranged to rotate around an axis 23 perpendicular to the moving direction of the paper 10.

Although not shown, the configuration includes a motor for rotating the impeller 19 inside the shaft 23.

Furthermore, a mechanism is provided at the bottom of the receiving tray 18 to repeatedly move the paper 10 in a direction perpendicular to the direction of the paper discharge movement force (in the direction of the arrow) in a horizontal plane. This mechanism has a structure in which the moving direction is switched by a signal from the recording device every time the document unit is switched.

[Effect]

That is, since the saucer tray 18 equipped with the reversing mechanism 22 is provided with the protrusion 5 and the connector 20 so as to engage with the hole 3 and the connector 21 on the recording device 2 side, the saucer tray 18 is provided with the protrusion 5 as a guide. The loading operation may be as simple as inserting the tray 18 into the recording device 2. By this insertion, the A points of the receiving tray 18 abut against the four points of the recording device 2, similar to the tray of the conventional normal rotation mechanism, and the fixing is stabilized by the own weight of the receiving tray 18. At this time, the connectors 20 and 21 are also connected together at the same time.

Moreover, when the tray 18 is to be removed from the recording apparatus 2, it is easy to remove the tray 18 from the recording apparatus 2, as it is only necessary to pull out the tray 18. Therefore, jammed paper can be easily removed.

Further, a repetitive movement mechanism provided on the receiving tray 18 moves the receiving tray 18' to the left and right in the figure in response to a signal from the apparatus side that is issued every time the document unit is changed, and the documents are separated and stacked.
