Abstract

PURPOSE:To correspond to the saving of space and to improve quality by freely rotatably installing an original tray. CONSTITUTION:The original tray 10 consists of a cover covering an original insertion port 4 when it is closed, a protection board covering an operation key 2 and a holding board abutting on a stopper 12 when it is opened. When the original tray 10 is in a closed state and is pulled to this side, a claw part 22 bends, engagement to a recessed part for engagement in a device main body is released and the original tray 10 becomes freely rotatable to a falcrum. When the original tray 10 is in an opened state, the original insertion port 4 is opened and the operation key 2 is exposed. When an original 3 is set in an original insertion tray 5, the original 3 is guided to the original insertion port 4 and the operation key 2 is operated. Thus, the original 3 is read and transported by a read mechanism 6. The original 3 whose reading is terminated is discharged to the outside of the device from an original excharge port 9, and it is received by the original tray 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus such as a wall-mounted type facsimile apparatus having a document tray which can be opened and closed with respect to the apparatus main body.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a wall-mounted type facsimile apparatus has a reading mechanism 30 on the upper side of the apparatus and a recording mechanism 31 on the lower side, and a document insertion port for inserting a document 32 to be transmitted. Reference numeral 33 is formed on the upper surface of the apparatus so that the original 32 can be easily inserted. The original 32 inserted through the original insertion port 33 is conveyed to the reading head 35 by the original feeding roller 34 provided downstream of the original insertion port 33 in the original conveyance direction, and the image is read. When the reading of the image is completed, the original 32 is discharged from the lower side of the front side of the apparatus to the outside of the apparatus.
6 is arranged at a predetermined angle with respect to the apparatus main body,
The discharged original 32 is received by the original tray 36.

A recording paper 38 stored in a recording paper holder 37 arranged at the lower part of the apparatus is conveyed by a print head 40 while being conveyed by a platen 39 provided downstream of the recording paper holder 37 in the recording paper conveyance direction. The image is recorded. When the recording of the image is completed, the recording paper 38 is ejected from the lower side of the apparatus to the outside of the apparatus, but the recording paper tray 41 is vertically provided on the lower surface of the apparatus, and the ejected recording paper 38 is the recording paper 38. Received by the tray 41. Further, an operation panel 42 is arranged on the upper side of the front surface of the device, and the operation panel 4
An operation key 43 and the like are attached to the upper part of the device 2, and the operation is performed here.

[0004]

However, in the above wall-mounted facsimile apparatus, the original tray and the recording paper tray are fixedly provided on the front and lower surfaces of the apparatus, and the original tray is located in front of the lower side of the front of the apparatus. Since it is provided in a protruding state, the installation space becomes large, and the original advantage of the wall-mounted facsimile apparatus of space saving is lost. Further, even though the document insertion port is formed on the upper surface of the apparatus, since it does not have a lid that covers the document insertion port, dust and the like are easily mixed. Therefore, dust and the like may adhere to the feed roller and the reading head, causing deterioration in the reading quality of the original. Further, since the operation keys are exposed on the front surface of the device and a cover for protecting the operation keys is not provided, a part of the human body comes into contact with the operation keys, which may cause a malfunction.

The present invention solves the above-mentioned problems. In the image forming apparatus, the original tray is rotatably mounted, so that it is possible to realize space saving and quality improvement. The purpose is to provide.

[0006]

In order to achieve the above object, the present invention is a tray which is rotatably attached to an apparatus main body and serves as a tray on which an original document is placed when the apparatus main body is opened and when the apparatus is closed. A document tray that can serve as a protective cover, a stopper that holds the document tray at a predetermined angle when the document tray is opened, and a lock that fixes the document tray to the device body when the document tray is closed And means.

[0007]

According to the above construction, the original tray is rotatably attached to the main body of the apparatus, and when the original tray is opened,
The tray serves as a tray that receives the ejected document, which is held at a predetermined angle with respect to the main body of the apparatus. Also,
When it is closed, it covers the device and is fixed to the device body by the locking means to protect the device.
