Abstract
Abstract An ozone removing device suitable for use in an image forming apparatus using an electrophotographic process, such as a copier, a laser printer or a facsimile machine, includes a container for containing therein a quantity of a volatile ozone removing agent. Thus, the vaporized or volatilized ozone removing agent flows out of the container through its mount and diffuses into the surrounding atmosphere where it decomposes and removes the ozone when encountered. A filter formed with a plurality of through-holes is fixedly attached to the mouth of the container so that the rate of volatilization of the volatile ozone removing agent is properly controlled, to thereby provide a prolonged ozone removing action. Preferably, a seal is adhesively and sealingly attached to the filter to normally keep the through-holes closed. The seal is removed at least partly to set one or more of the through-holes open after placing the present ozone removing device in position.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
60 words
An ozone removing device comprising: a container for containing therein a quantity of volatile ozone removing agent; and controlling means for controlling the rate of volatilization of said volatile ozone removing agent; wherein said volatile ozone removing agent includes a mixture of terpenoid (general formula: C m H 2n+14 O p , m=9-15, n=0-4, p=0-2) and a glycol family material.
Claim 2
Dependent Claim
60 words
An ozone removing device comprising: a container for containing therein a quantity of volatile ozone removing agent; and controlling means for controlling the rate of volatilization of said volatile ozone removing agent; wherein said volatile ozone removing agent includes a mixture of terpenoid (general formula: C m H 2n+14 O p , m=9-15, n=0-4, p=0-2) and a glycol family material.
Claim 3
Dependent Claim
33 words
The device of claim 1, wherein said container has a mouth and said controlling means includes a filter fixedly attached to said mouth of said container and formed with a plurality of through-holes.
Claim 4
Dependent Claim
30 words
The device of claim 2, wherein said controlling means further includes a seal member which is detachably and sealingly attached to said filter to normally close all of said through-holes.
Claim 5
Dependent Claim
35 words
The device of claim 1 and an apparatus having an ozone generating source and a replaceable component, wherein said container is integrally formed with said replaceable component of said apparatus having said ozone generating source.
Claim 6
Dependent Claim
33 words
The structure of claim 4, wherein said apparatus is an image forming apparatus selected from the group consisting of a copier, a laser printer and a facsimile machine, which uses an electrophotographic process.
Claim 7
Dependent Claim
31 words
The structure of claim 4 wherein the quantity of said volatile ozone removing agent contained in said container is determined in consideration of a service life of said integrated replaceable component.
Claim 8
Dependent Claim
34 words
The device of claim 1, wherein said container includes a pair of tapes which are combined together to define a plurality of chambers therebetween, which chambers are filled with said volatile ozone removing agent.
Claim 9
Dependent Claim
23 words
The device of claim 7, wherein one of said pair of tapes is a wavy tape and the other is a flat tape.
Claim 10
Dependent Claim
29 words
The device of claim 7, wherein said controlling means covers at least one end of each said chambers to thereby control the volatilization of said volatile ozone removing agent.
Claim 11
Independent Claim
99 words
An apparatus having a housing which communicates with the ambient through apertures in said housing comprising: a device which is located inside the housing of said apparatus and generates ozone; a source which also is located inside the housing of said apparatus and produces a gaseous agent for removing said ozone, said source comprising a container containing therein a volatile material which produces said gaseous agent; and means for controlling the flow of said gaseous agent from said source into said apparatus, wherein said means comprises a filter disposed between said volatile agent and the interior of said apparatus.
Claim 12
Independent Claim
99 words
An apparatus having a housing which communicates with the ambient through apertures in said housing comprising: a device which is located inside the housing of said apparatus and generates ozone; a source which also is located inside the housing of said apparatus and produces a gaseous agent for removing said ozone, said source comprising a container containing therein a volatile material which produces said gaseous agent; and means for controlling the flow of said gaseous agent from said source into said apparatus, wherein said means comprises a filter disposed between said volatile agent and the interior of said apparatus.
Claim 13
Dependent Claim
22 words
An apparatus as in claim 10 in which said volatile material comprises a mixture of a terpenoid and a glycol family material.
Claim 14
Dependent Claim
26 words
An apparatus as in claim 11 in which said terpenoid has the general formula C m H 2n+14 O p , where m=9-15, n=0-4 and p=0-2.
Claim 15
Dependent Claim
26 words
An apparatus as in claim 12 comprising a photoconductive member and wherein said device which generates ozone comprises a corona member operatively associated with said member.
Claim 16
Dependent Claim
46 words
An apparatus as in claim 13 in which said apparatus includes an operative member having a selected service life and said container is integrally formed with said operative member and contains a quantity of said volatile material related to said service life of the operative member.
Claim 17
Dependent Claim
31 words
An apparatus as in claim 14 in which said container is in the form of two tapes secured to each other to form a plurality of chambers for said volatile material.
