Description

[Detailed Description of the Invention] The present invention relates to an electrophotographic copying apparatus.

In conventional electrophotographic copying machines, the accessories used, such as the paper output tray and paper feed tray, are either fixed to the copying machine body or detachable, which makes logistics and transportation time-consuming and space-inefficient. There was a problem. The purpose of the present invention is to improve transportation efficiency by quickly folding the paper discharge tray, paper feed tray, etc. that are sorted into an electrophotographic copying device with a single touch to make them more compact.

In order to achieve the above object, the electrophotographic copying apparatus of the present invention includes a main body, a pressure plate that is provided on the main body and is movable between a position where an original is pressed and held and a position where it is not held under pressure, and a pressure plate that protrudes from the main body of the apparatus. The apparatus includes a sheet placing member that is movable between a first position where a sheet can be placed and a second position where movement of the pressure plate is restricted along the apparatus main body.

Embodiments of the electrophotographic copying apparatus according to the present invention will be described below with reference to FIGS. 1 to 3. In the figure, 1 is the main body of the electrophotographic copying device, 2
and 3 are plate-shaped members on opposite sides, which are used as tables on which materials are placed when the machine is in use;
In the illustrated embodiment, 2 indicates a paper feed tray, and 3 indicates a paper discharge tray. A pressure plate 4 that presses and holds a document is provided on the top surface of the machine body 1. During copying, the copy paper is placed on the paper feed table 2, and the copy paper is placed on the machine main body 1.
The copy paper that has been copied is fed into the tray 3.
sent out on top of

In the illustrated embodiment, the paper feed tray 2 is rotated upward toward the side of the machine body by a rotating shaft 6 (see FIG. 3) supported by a bearing 5 provided protruding from the side of the machine body. It is pivoted so that it can be However, in order to hold the paper feed tray 2 at an angle that optimally satisfies the copying function with respect to the machine body 1 when using the copying machine, a paper feed tray rotation stopper 7 is provided near the paper feed opening of the main body 1. is provided so as to correspond to a claw 8 provided on an extension of the paper feed table. Also, paper output tray 3
is similarly pivoted to the side of the machine body 1 so as to be able to rotate upwardly by a rotating shaft (not shown) supported by a bearing 9 protruding from the other side of the machine body. Moreover, when the copying machine is used, the paper delivery tray 3 is held at an angle that optimally satisfies the copying function with respect to the main body of the machine.

However, the paper feed tray 2 and the paper discharge tray 3 are each bent over the top of the machine body 1 and are configured to abut against each other at the top of the machine body, and in the illustrated embodiment, the paper feed tray 2 is composed of two members 2a and 2b, and the paper discharge tray 3 is composed of two members 2a and 2b.
It is composed of two members 3a and 3b. In the illustrated example, the paper feed tray and the paper discharge tray have exactly the same configuration, so only the configuration of the paper feed tray 2 will be described below. Two members 2 of paper feed tray 2
a and 2b are connected so as to be bendable by the rotating shaft 10, and the inner member 2
A rotation stopper 11 is provided on the outside of a, and a claw 12 provided on the outside member 2b comes into contact with the rotation stopper 11 to hold the outside member 2b of the paper feed tray at a constant angle.

Handle forming portions 13 and 14 are provided at the tips of the paper feed tray 2 and the paper discharge tray 3, which cooperate with each other to form a transportation handle when these are brought together on the machine body. These handle forming parts 13 and 14 are
When the main body of the machine is placed on the support surface and the paper feed tray 2 and the paper ejection tray 3 are extended to both sides of the machine body, a base is formed to support the paper feed tray and the paper ejection tray on the above-mentioned support surface. Just do it like this.

In the electronic copying device described above, when using the machine, as shown in Figure 1, if the paper feed tray 2 and paper output tray 3 are extended to the sides of the machine body, the paper feed tray and paper output tray will be correctly aligned. It is held in position and at an angle that optimally satisfies the copying function.

However, during transportation, by folding the paper feed tray and the paper output tray upward as shown in Figure 2, the paper feed tray and output tray can be used as a cover that protects at least three sides of the main body, and the pressure plate It can be carried by holding the handle formed by the handle forming parts 13 and 14 in the hand.

In the electrophotographic copying apparatus according to the present invention, the sheet placing member is movable from a use position where sheets can be placed to a second position suitable for transporting along the main body of the apparatus, greatly improving transport efficiency. It is intended to improve the performance.

Furthermore, during transportation of the device, it prevents the pressure plate from moving due to vibration or tilting of the device, and prevents the pressure plate and device from being damaged or dropped, enabling safe transportation. It is something to do.
