Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a copying machine featuring a toner supply mechanism.

(Prior art) Small copying machines that use a dry development method have a structure in which the toner cartridge holder is opened after opening the manual feed table due to the compactness of the device and space constraints. When the cartridge is removed, the toner adhering to its surface falls onto the manual feed table, which has the disadvantage of contaminating the transfer machine during manual paper feeding.

(Purpose) The present invention was developed in view of this type of inconvenience, and its purpose is to prevent toner from falling onto the manual feed table when replacing the toner cartridge by using an inner cover. An object of the present invention is to provide an improved copying machine that can prevent the above problems.

(Means for Achieving the Object) The present invention provides a copying machine for achieving the above object, between a manual paper feed table rotatably attached to one side of the copying machine body and a toner cartridge holder. An inner cover member is disposed at a position that prevents rotation of the toner cartridge holder in the closed state, rotates to a position that covers the manual feed table in the open state, and is covered by the manual feed table when the manual feed table is in the closed position. This is how it was done.

(Example) Hereinafter, details of the present invention will be explained with reference to drawings showing the operating state.

In the figure, reference numeral 1 denotes a main body of the copying machine, and a cassette 2 is removably attached to one side of the main body. Reference numeral 3 denotes a manual feed table that rotates between a set position and a manual paper feed position around a fulcrum (not shown) provided above the cassette 2. Inside this table, when the table 3 is rotated to the paper feed position (second The inner cover 5 is attached so that it can rotate around a fulcrum (not shown) to prevent the interior of the machine from being exposed and to prevent fingers from coming into contact with rotating parts, etc., and the toner cartridge is in the closed position. The tray holder 4 is prevented from rotating and covers the manual feed table 3 in the open position.

In the figure, reference numeral 6 indicates a toner cartridge which is attached and detached by rotating the toner cartridge holder 4 about a fulcrum (not shown), and 7 indicates a copy tray.

FIG. 1 shows the normal copying state or standby state using the transfer paper in the cassette 2. In this state, the manual feed table 3 is in the set position, covers the inner cover 5, and the copying machine is placed on its underside. It covers the outer surface of 1.

Figure 2 shows the state in which the manual feed table 3 is rotated half a turn around the fulcrum above the cassette 2 from this state.
By sliding the desired manual paper P onto the table 3, manual copying can be performed. In this state, the inner cover 5 is positioned to cover the inside of the copying machine 1, and its upper end is in a position to prevent the toner cartridge holder 4 from rotating.

When the toner in the toner cartridge 6 is completely consumed, a toner end display lights up. This display allows the operator to insert the inner cover 5 into the manual feed table 3 in order to replace it with a new toner cartridge 6.
When placed on top, the toner cartridge holder 4 becomes rotatable, so open it (FIG. 3) and replace the old and new toner cartridge 6.

At this time, even if toner spills from the old toner cartridge 6, the manual feed table 3
Since the top surface of is covered with the inner cover 5,
There is no possibility that the transfer paper etc. will be contaminated.

(Effects) As explained above, according to the present invention, the inner cover is inserted between the manual feed table and the toner cartridge holder, and when the inner cover is in the closed state, that is, when the table is in the manual paper feeding state, The toner cartridge holder cannot be opened, and the inner cover is placed on the table when the toner cartridge can be replaced. This prevents contamination of the manual feed table when replenishing toner, which tends to occur with small copiers. , it is possible to completely prevent operational errors without leaving any room for intervention.
