Description

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, a recording apparatus according to the present invention according to a first aspect of the invention comprises a paper tray for stacking recording paper and a separate conveyance of the recording paper one by one. In a recording apparatus including a sheet feeding mechanism, a conveying mechanism for conveying the separated recording sheets, and a recording unit for recording on the recording sheets, a first position during recording and a non-recording position. It has the paper tray movable to the second position.

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.

In order to achieve the above-mentioned object, the recording apparatus according to the present invention as defined in claim 2 is a motive power for moving the paper tray between the first position and the second position in the invention according to claim 1. It is characterized by using a paper conveying motor of the recording apparatus.

With this configuration, the paper tray uses the paper transport motor (pulse motor or the like) of the recording apparatus,
It is possible to make the first and second positions movable.

To achieve the above object, a recording apparatus according to the present invention according to claim 3 records the recording sheet by hand in the recording apparatus at the second position of the sheet tray in the invention according to claim 1. It is characterized by having a guide for.

With this configuration, when the paper tray is stored 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, a recording apparatus according to the present invention as defined in claim 4 is the recording apparatus according to claim 1 or 2, wherein the movement of the paper tray from the second position to the first position is a recording operation. It is characterized in that it has a control means for automatically performing a printing start command to the apparatus.

With this configuration, the paper tray can be automatically moved from the above-mentioned second position to the first position by a print start command.

[0019]

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.
