DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper feeding device for a recording device such as a page printer, a facsimile, a copying machine, or the like, which feeds recording paper stored in a paper feeding cassette.

[0002]

2. Description of the Related Art Paper feeders of the above type are well known. In this type of paper feeder, fixed-size papers such as A-series and B-series are used as recording papers. It is set in the recording device. In recent years, recording apparatuses have been increasingly required to be reduced in size and space.

[0003]

However, in the conventional paper feeder, the paper feed cassette is mounted so that the stored recording paper is horizontal, so that it is possible to respond to the demand for miniaturization and space saving of the recording equipment. Was at the limit.

The present invention has been made in view of the above-described conventional problems, and has as its object to provide a paper feeder that enables a drastic reduction in the size of a recording apparatus and that allows easy supply of recording paper.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a recording apparatus in which a recording sheet accommodated in a sheet feeding cassette is detachably mounted on a main body of a recording apparatus in a direction in which the recording sheet stands substantially vertically. In a sheet feeding device of a recording device that is pulled out toward the front side in a state of being erected from a side portion of the recording device main body, an upper opening as a recording paper replenishing unit is provided at an upper portion of the paper feeding cassette. A supply port communicating with the upper opening is provided, and recording paper can be supplied to the sheet cassette through the supply port and the upper opening.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is an explanatory diagram of a laser printer provided with a sheet feeding device according to the present invention. In FIG. 1, reference numeral 1 denotes a main body of a laser printer as a recording device, and a photosensitive belt 2 is wound around three rollers 3 substantially at the center of the printer main body 1. Around the photoreceptor belt 2,
The charging charger 4, the incident position of the writing laser beam L from the optical writing means 5, the developing device 6, the transfer charger 7, and the cleaning means 8 are arranged in the order of the rotation indicated by the arrow. An optical writing means 5 is disposed below these electrophotographic processing means, and a paper feeder 10 is provided on the right side of the printer body 1.

The paper feeder 10 is provided with a paper feed cassette 11 containing standard recording paper P and a paper feed separation unit 12 for feeding paper one by one from the paper feed cassette 11. Is composed of a paper feed roller 13 and a separation roller 14. The recording paper P fed by the paper feed roller 13 is
The photoconductor belt 2 is conveyed to a transfer section between the transfer charger 7 and the left side of the photoconductor belt 2 at a timing by the registration roller pair 15. The toner image formed on the photosensitive drum 1 through the steps of uniform charging by the charging charger 4, optical writing by the writing laser beam L, and development by the developing device 6 is recorded under the action of the transfer charger 7. The image is transferred to paper P.
The recording paper P on which the toner image has been transferred is fixed by a fixing device 17 and then discharged outside the apparatus by a discharge roller pair 18.

As shown in FIG. 2, the paper feeding device 10 of the present invention stores recording paper P in a paper feeding cassette 11 in an upright state. As shown in FIG. 1, the paper feed cassette 11 is detachably mounted on the printer main body 1 with the stored recording papers P standing almost vertically. Therefore, since the recording paper is not set in the horizontal direction, the printer main body 1 can be made vertically long, and the area occupied by the laser printer can be drastically reduced.

Next, the replenishment of the recording paper in the paper feed cassette which accommodates the recording paper P in a state of being set substantially vertically will be described.

The paper cassette 11 is configured to be detachable from the side of the printer body 1, and the paper cassette 11 can be pulled out toward the operator as shown in FIG. Accordingly, when the recording paper P stored in the paper feed cassette 11 runs out, the operator pulls out the paper feed cassette 11 to the front side and can supply the paper from the upper opening 20 as a recording paper supply unit as shown in FIG. Therefore, the setting of the recording paper P is very simple even in the paper feed cassette 11 which stores the recording paper P in a state of being substantially vertically erected.

FIG. 5 is a perspective view showing another embodiment of the present invention. In this embodiment, a side surface opening 22 is provided on a side surface of the sheet cassette 11 parallel to the paper surface as a recording sheet supply unit, and the side surface opening 22 is covered by a side plate cover that is openably and closably attached to the cassette. . The opened / closed side plate cover 21 is formed to be equal to or slightly larger than the recording paper P to be set, so that the recording paper P can be set from the paper surface direction.

The paper feeder 10 thus constructed draws out the paper feed cassette 11 from the side of the printer body 1 toward the operator, so that the recording paper P can be replenished without any extra operation for the operator to stand up. .

The paper supply cassette 11 of the paper supply device 10 is provided with two supply portions, an upper opening 20 and a side opening 22, so that a user can selectively use a convenient one. Can also.

FIG. 6 is a perspective view showing still another embodiment of the present invention. In this embodiment, a replenishing port 24, which is normally closed by an opening / closing cover 23, is provided at the upper part of the printer main body 1, and the replenishing port 24 communicates with the upper opening 20 of the sheet cassette 11 shown in FIG. Here, when replenishing the recording paper P to the paper feed cassette 11, the opening / closing cover 23 is opened,
Replenish from here.

In the paper feeding apparatus 10 having the above-described configuration, the recording paper P can be supplied to the paper feeding cassette 11 by opening the opening / closing cover 23 of the printer main body 1, so that the feeding can be performed without pulling out the paper feeding cassette 11. .

[0021]

According to the first aspect of the present invention, an upper opening serving as a recording paper supply section is provided above the paper feed cassette, and a supply port communicating with the upper opening is provided above the recording apparatus main body. Since the recording paper can be supplied to the paper cassette through the upper opening, the recording paper can be supplied to the paper cassette from the opening of the recording apparatus without opening the paper cassette.
