[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electronic device with a printing unit and a display unit.

[0002]

[Prior Art]

 Conventionally, in a desktop personal computer or word processor, when a display device and a printing device are separately supplied, a dedicated stand is often used to place the printing device on a shelf above the display device.

In a small-sized word processor, a display device and a printing device are integrated into one frame, but an automatic paper feeding device that feeds printing paper to the printing device one by one is supplied separately from the word processor main body. Then, the word processor is projected backward and upward and left as it is.

Further, as described in JP-A-59-184682, it has been proposed that a roll paper and a printing device are horizontally arranged below a display device and a printed paper is ejected from the front surface. ing.

[0005]

[Problems to be solved by the device]

 However, in the case of using a dedicated stand, the position of the printing device is higher than the height of the eyes of the user, and therefore the user must stand up to check the printing and take out the printed paper. Furthermore, in this case, the automatic paper feeding device is supplied separately from the printing device and is installed so as to project backward and upward, which makes the size very large.

Even a small-sized word processor requires a large installation space because the automatic paper feeding device is overhanging.

Further, in the case where the roll paper and the printing device are placed under the display device, the size is also large in the front-rear direction, and the installation place is wide. Further, with this structure, when the stacked printing papers are placed horizontally, the dimension in the front-back direction becomes larger, which is not suitable for the demand for using the automatic paper feeder.

The present invention provides an electronic device, such as a personal computer or a word processor, which is small in size, particularly small in the front-rear direction, and capable of feeding printing sheets one by one.

[0009]

A sheet feeding means, and the base member, the display section and the sheet storage section are arranged substantially parallel to each other and substantially vertically.

Further, in the above structure, the display device is arranged on the front surface of the base member, and the paper storage section is arranged on the rear surface side of the base member.

Further, in the above-mentioned configuration, the printing unit is arranged above the base member, and the printing paper is sent out from the paper storage to the printing unit upward by the paper feeding unit. Alternatively, the printing unit is disposed below the base member, and the base member is provided with a discharge port for printed paper under the display unit, and the printing paper is discharged downward from the paper storage unit toward the printing unit. The printing paper is fed by the paper feeding means.

Furthermore, in the above structure, the electronic device of the present invention has a keyboard for input.

[0013]

[Action]

 In the above electronic device, a circuit board for a personal computer or a word processor can be stored in a base member in a substantially vertical shape, and a printing paper can be stored in a paper storage portion in a substantially vertical shape. When printing, the printing paper is sent out from the paper storage unit in a substantially vertical direction and supplied to the printing unit. The display part can have a large area that is almost the same as the paper storage part when viewed in the horizontal direction. Furthermore, by arranging the base member, the display unit, and the paper storage unit substantially vertically with respect to each other, the overall size in the front-back direction can be reduced.
