Claims
- 1. A film photoconductor holding mechanism, comprising:
- a substantially-cylindrical support having an opening which is shaped so as to have a notch at a part of a circumferential portion of said support in a longitudinal direction thereof;
- a bar-like photoconductor cap which is operative to engage with said opening of said support;
- a film assembly having a peripheral length larger than an outer peripheral length of said support and being installed into said support in a state where said bar-like photoconductor cap is opened and being held in said support by said bar-like photoconductor cap;
- a guide bar, disposed on said film assembly, for guiding the installation of said film assembly in said support; and
- a guide groove defined in said bar-like photoconductor cap and engaged with said guide bar.
- 2. The film photoconductor holding mechanism as claimed in claim 1, wherein said film assembly has an elastic member that holds said film assembly in said support by a predetermined tension after said film assembly has been installed in said support.
- 3. A film photoconductor which is held by a substantially-cylindrical support having an opening which is shaped so as to have a notch at a part of a circumferential portion of said support in a longitudinal direction thereof, said film photoconductor comprising:
- a film which defines a side surface; and
- a guide bar, disposed at the side surface of the film of said film photoconductor, for guiding installation of the film in said support.
- 4. A film photoconductor which is held by a substantially-cylindrical support having an opening which is shaped so as to have a notch at a part of a circumferential portion of said support in a longitudinal direction thereof, said film photoconductor comprising:
- a film which defines a side surface; and
- an elastic member, disposed at the side surface of the film of said film photoconductor, for holding the film in said support by a predetermined tension after the film has been installed in said support.
- 5. A film photoconductor which is held by a substantially-cylindrical support having an opening which is shaped so as to have a notch at a part of a circumferential portion of said support in a longitudinal direction thereof, said film photoconductor comprising:
- a film which defines a side surface;
- a guide bar, disposed at the side surface of the film of said film photoconductor, for guiding installation of the film in said support; and
- an elastic member, disposed at the side surface of the film of said film photoconductor, for holding the film in said support by a predetermined tension after the film has been installed in said support.
- 6. The film photoconductor as claimed in claim 5, wherein said, guide bar and said elastic member are formed integrally with each other.
- 7. The film photoconductor as claimed in claim 5, wherein said film photoconductor is formed into an endless shape by joining both ends of the film to each other at a joint portion, and a member having said elastic member integrated with said guide bar is engaged with the joint portion of the film.
- 8. A film photoconductor holding mechanism, comprising:
- a substantially-cylindrical support having an opening which is shaped so as to have a notch at a part of a circumferential portion of said support in a longitudinal direction thereof;
- a bar-like photoconductor cap which is operative to engage with said opening of said support;
- a film having a peripheral length larger than an outer peripheral length of said support and being installed into said support in a state where said bar-like photoconductor cap is opened and being held in said support by said bar-like photoconductor cap; and
- a guide ring, disposed in an end portion of said support in the longitudinal direction thereof, for shaping the film when installing the film into said support and for guiding engagement of the film during installation.
- 9. The film photoconductor holding mechanism as claimed in claim 8, wherein said guide ring has a tapered side surface.
