Further, by providing a hole serving as a see-through window in the outer cover of the copying device, there was a problem that the external design was somewhat inferior.

In view of the above problems, the present invention provides a copying apparatus in which the toner color and remaining amount of toner in a developing unit within the copying apparatus can be easily viewed from outside the copying apparatus without degrading the external design.

Means for Solving the Problems In order to solve the above problems, the copying apparatus of the present invention is provided with a see-through window in the exterior cover of the copying machine, a lid that engages with the window via a spring, and a lid that engages with the window. It has a structure with a mirror attached to the inside.

Effect of the Invention With the above-described configuration, when you want to check the toner color and remaining amount of toner in the developing unit inside the copying machine, by pressing the lid, the developing unit inside the copying machine is displayed through the mirror inside the lid while standing in a standing position. You can easily see the toner color and remaining amount of toner. Furthermore, when you stop pressing the lid, the spring closes the lid, which closes the see-through window provided in the outer cover of the copying device, which improves the appearance without degrading the external design.

Embodiment Hereinafter, a copying apparatus according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a copying apparatus according to an embodiment of the present invention, in which 1 is an openable and closable outer cover 2 of the copying apparatus, and 3 is a lid that is engaged with the outer cover 1, and 3 is attached to the inner surface of the copying apparatus. The reference numeral 4 represents a developing unit that is removably installed inside the copying apparatus. Note that a unit may be formed in which a photoreceptor and image forming means such as a developing device and a cleaning means are integrated around the photoreceptor.

FIGS. 2(a) and 2(b) are sectional views of essential parts of the transparent window portion of the outer cover of the copying apparatus. (a) shows the state in which the lid 2 is closed, 5 indicates the toner color and remaining amount of toner provided on the developing unit 4, 6 indicates the rotation fulcrum of M2, and 7 indicates the see-through window provided on the exterior cover 1. It is. (b) shows the state where M2 is opened, and 8 shows the user's viewpoint. Further, M2 is provided at a position corresponding to the characteristic display of the developing unit.

FIGS. 3(a) and 3(b) are enlarged sectional views of main parts of the transparent window section of the exterior cover, and M2 is a spring 1 attached to the rotational fulcrum 6 of the exterior cover 1.
One end of the spring 10 is engaged with a stopper portion 9 formed on the exterior cover 1, and the other end is engaged with the lid 2.

The operation of the copying apparatus configured as described above will be explained below.

A developing unit 4 having characteristics (for example, a desired color) that matches the needs of the user is installed in the copying device, and as copies are made, a toner remaining amount display 5 provided on the developing unit 4 changes. . That is, the toner color and remaining amount of toner in the developing unit 4 installed in the copying apparatus can be visually recognized by the display 5. the user,
To check the toner color and remaining amount of toner in the developing unit 4 currently installed in the copying machine,
There is no need to open the exterior cover 1 of the copying machine (opening the exterior cover 1 turns off the power to the copying machine, and even if you close the exterior cover 1 and turn on the power, it will take some time for it to be ready for copying). As shown in Fig. 2(b) and Fig. 3(b), by pushing open the lid 2 engaged with the outer cover 1, the user can view the inside of M2 from a high point of view where the user normally stands and uses the copying machine. The toner color and remaining amount of toner in the developing unit 4 is displayed through an optically open see-through window 7 formed in the exterior cover 1 through a mirror attached to the side surface.
