2. Description of the Related Art In an image forming apparatus such as a copying machine or a printer, an openable / closable door is attached to a side surface of a main body so that general users can easily perform maintenance, replenishment of transfer paper, and processing of paper jam. In most cases. For example, two doors 51a and 51b for replenishing the roll transfer paper set inside the main body are also attached to the front surface of the copying machine Z0 for large format paper shown in FIG. Since it is necessary to open the front surface of the main body largely in order to replenish the large-sized roll transfer paper, the doors 51a and 51b can be opened and closed in a double door type as shown by the arrow in FIG. In the copying machine Z0, as shown in FIG.

However, since metal has a low degree of freedom during molding, it is difficult to realize a smooth shape with many curves, which is disadvantageous in design as compared with a plastic resin door or the like. There was a problem that was. However, it is difficult to secure sufficient strength when a large door such as the copying machine Z0 is formed of only plastic resin. Therefore, the door itself is made of resin,
It is conceivable to attach a metallic reinforcing member to the inner surface of the door, which is hidden when the door is closed. However, as long as the number of members is increased, it is desirable that the members are not only used for reinforcement but also for other purposes. Further, since the door is frequently opened and closed by the user, it is not good in appearance that the obvious reinforcing member is seen and hidden inside the door. The present invention has been made in view of the above circumstances, and an object of the present invention is to make a door of an image forming apparatus made of resin, which is a design priority, and a reinforcing member attached for the purpose of reinforcing the door. Another object of the present invention is to provide a door structure for an image forming apparatus that can be effectively used.

[0004]

[Means for Solving the Problems] Usually, documents such as a manual are attached to an image forming apparatus such as a copying machine.
These must be kept near the main body. However, since these documents are often stored in another bookshelf, the manual cannot be found immediately when a paper jam occurs or a malfunction occurs, and it often takes time to restore the manual. Therefore, it is convenient if the main body of the image forming apparatus has a space for storing documents such as the manual. Therefore, in order to achieve the above object, the present invention provides a door structure of an image forming apparatus, which is attached to a side surface of an image forming apparatus main body so as to be openable and closable, in which the door is formed of resin and the inner surface side of the door is formed. The door structure of the image forming apparatus is characterized in that a metal reinforcing member that doubles as a storage member for storing documents is attached. As a result, the reinforcing member can be effectively used as a storage member for storing documents and the like while achieving both the design and strength of the door of the image forming apparatus.
The reinforcing member is, for example, two left and right vertical members fixed to the inner surface of the door, and a horizontal member that connects the two vertical members with a gap formed between the vertical member and the inner surface of the door. Can be composed of For example, the above two vertical members are
Each of them is fixed near the both side edges of the door, and is approximately vertical in the door.
It should be all over.
