Abstract
Abstract A full waste toner container detector comprises a waste toner container for storing waste toner collected from the photoreceptor surface, a flexible film member which projects into the container when the container is not filled up with waste toner and projects outwardly from the container due to the waste toner pressure when the container is full of waste toner, a reflection plate mounted on the external surface of the flexible member, a light source for irradiating the reflection plate, and a sensor provided in such a position as to receive light reflected by the reflection plate when the flexible member projects outwardly from the container.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
52 words
A waste toner container for storing waste toner particles remaining on photoreceptor means after electrophotography, comprising: flexible film means provided on said waste toner container; and sensor means for sensing the expansion of said flexible film means on the condition that the waste toner container is full of the waste toner particles.
Claim 2
Dependent Claim
52 words
A waste toner container for storing waste toner particles remaining on photoreceptor means after electrophotography, comprising: flexible film means provided on said waste toner container; and sensor means for sensing the expansion of said flexible film means on the condition that the waste toner container is full of the waste toner particles.
Claim 3
Dependent Claim
15 words
The waste toner container of claim 1, wherein said sensor means comprises optical sensor means.
Claim 4
Dependent Claim
111 words
A full waste toner container detector comprising: a waste toner container for storing waste toner particles collected from photoreceptor means; a flexible film means which projects into said container when said container is not filled up with the waste toner particles and projects outwardly from said container due to the waste toner pressure when said container is full of the waste toner particles; a reflection plate mounted on the external surface of said flexible means; a light source for irradiating said reflection plate; and a sensor means provided in such a position as to receive the light reflected by said reflection plate when said flexible means projects outwardly from said container.
Claim 5
Dependent Claim
111 words
A full waste toner container detector comprising: a waste toner container for storing waste toner particles collected from photoreceptor means; a flexible film means which projects into said container when said container is not filled up with the waste toner particles and projects outwardly from said container due to the waste toner pressure when said container is full of the waste toner particles; a reflection plate mounted on the external surface of said flexible means; a light source for irradiating said reflection plate; and a sensor means provided in such a position as to receive the light reflected by said reflection plate when said flexible means projects outwardly from said container.
Claim 6
Dependent Claim
25 words
The full waste toner container detector of claim 3, wherein said light source is the one used for irradiating a document on a copying machine.
Claim 7
Dependent Claim
46 words
The full waste toner container detector of claim 4, wherein said flexible means is integrally provided with a cartridge in which the photoreceptor means and the peripheral parts thereof such as the waste toner container are integrally provided, said cartridge being detachable from the copying machine.
Claim 8
Dependent Claim
85 words
An assembly for the collection of excess developer material from an image-bearing member in an electrographic image recording apparatus, the assembly comprising a receptacle for receiving said excess material and means for detecting when a given amount of said material is contained in said receptacle, characterized in that said detecting means comprises a displaceable element arranged to be pushed outwardly with respect to a wall of said receptacle by the material accummulating therein, and a sensor arranged to sense the outward displacement of said element.
Claim 9
Dependent Claim
85 words
An assembly for the collection of excess developer material from an image-bearing member in an electrographic image recording apparatus, the assembly comprising a receptacle for receiving said excess material and means for detecting when a given amount of said material is contained in said receptacle, characterized in that said detecting means comprises a displaceable element arranged to be pushed outwardly with respect to a wall of said receptacle by the material accummulating therein, and a sensor arranged to sense the outward displacement of said element.
Claim 10
Dependent Claim
40 words
An assembly according to claim 6 wherein said displaceable element comprises a flexible, thin-walled cup which normally projects inwardly of the receptacle wall, and which inverts so as to project outwardly of said wall by pressure of the accumulated material.
Claim 11
Dependent Claim
39 words
An assembly according to claim 6 or claim 7 wherein a reflector is attached to said displaceable element, and a light sensor is arranged to sense the outward displacement of said element by sensing light reflected from said reflector.
