Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus having a built-in automatic sheet feeding device for sequentially separating and conveying stacked recording sheets.

[0002]

2. Description of the Related Art Conventionally, in this type of recording apparatus, since the recording sheet is mainly vertically long, the sheet is often conveyed in the vertical direction, and therefore the width of the recording mechanism and the apparatus can be minimized. There was no choice but to grow in the front-back direction.

In the conventional example 1, the sheets are stacked on the front side, U-turned by the paper feed roller, printed immediately after that, and discharged to the front side. Is added.

The conventional example 2 is a system in which a sheet is supplied from an obliquely rear side of the apparatus, passes through a recording portion, and is discharged to the front side.

[0005]

In a printing / recording apparatus for a personal use computer, the waiting time is much longer than the printing time, and the occupied space is maximized when not in use. There was a request to make it smaller.

In the prior art example 1, the U-turn path minimizes the area occupied by the sheets, but since the depth of the apparatus and the length of the stacked sheets in the vertical direction are added, the sheet is installed only in a place with a space in the depth direction. This is not possible, and since the area occupied by the device itself becomes large, there is a drawback that the installation place is limited.

Further, in the conventional example 2, since the stacked sheets are located diagonally rearward, the depth of the entire apparatus when not in use can be reduced, but the overall height of the apparatus becomes high, so that the shelf or the like cannot be used. You can not place it in a place where there is a restriction in the height direction,
After all, there was a drawback that the installation place was limited.

An object of the present invention is to miniaturize the apparatus so that the installation space is the smallest when not in use, and to effectively utilize the space. Another object of the present invention is to provide a recording apparatus which has good operability for paper handling.

[0009]

In order to achieve the above object, the recording apparatus according to claim 1 records by the recording means.
Paper for stacking recording paper in the recording device
Paper feed for separating and transporting tray and recording paper one by one
Conveying recording paper separated by the mechanism and the paper feeding mechanism
And a transport mechanism for
The first position in the continuous feeding state is driven by the paper transport motor.
And location, this is movable and the second position of the non-recording state, the
And are characterized by.

With this configuration, it is possible to prevent the paper tray from occupying the space while the recording apparatus is on standby.

Further, the paper tray can be housed in the apparatus by rotating about the rotation axis or moving in parallel to the apparatus.

Further, it is possible to completely cover the paper when the paper tray is stored in the apparatus.

Further , the paper tray can be moved between the first and second positions by using a paper carrying motor (pulse motor or the like) of the recording apparatus.

In order to achieve the above object, claim 2 is set forth.
In the invention according to claim 1, the recording device is the second device.
At the position to manually feed the recording paper
It is characterized by having a guide .

With this configuration, when the paper tray is housed in the apparatus, an opening for manual sheet feeding and a guide portion can be formed, and the paper is manually fed to the recording apparatus to record. can do.

In order to achieve the above object, the third aspect of the present invention is provided.
The recording device is the same as the recording device according to the invention described in claim 1 or 2.
The paper tray from the second position
It is characterized in that it is automatically moved to the first position .

With this structure, the paper tray is set to print.
It is possible to automatically move from the above-mentioned second position to the first position by a decree .

[0018]

According to the present invention, since the paper tray that occupies the space when not printing can be stored in the main body device, not only the working space can be effectively utilized but also the paper tray is loaded on the paper tray. You can also protect the paper from dust and moisture. Further, in the case of manual paper feeding, if the paper tray is accommodated and the manual paper feeding opening and guide portion are formed, the paper tray and the stacked papers do not get in the way, A recording device with good operability can be provided.
