Abstract
Abstract A reader printer includes a rotatable scanning mirror disposed in an optical path formed between a projection lens and a printer section in correspondence with a printer mode, the scanning mirror being rotated to perform scanning of an image and a movable mirror disposed near such a printer mode optical path for movement between an inserted position where it is inserted in the optical path and a retracted position to which it is retracted from the optical path. Movement of the movable mirror causes mutual switching between the printer mode optical path and the reader mode optical path.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
139 words
A reader printer comprising: a focusing lens for focusing light rays passing therethrough: first optical means for directing light rays passing through said focusing lens to a movable recording medium, said first optical means including a rotatable first mirror; drive means for rotating said first mirror from a first angled state to a second angled state at a constant speed during movement of the recording medium; second optical means for directing light rays reflected from said first mirror toward a screen, said second optical means including a second mirror movable between an inserted position wherein it is inserted in a reflection optical path formed by reflection from said first mirror and a retracted position wherein it is retracted from the reflection optical path; and means for moving said second mirror in a direction substantially parallel to its reflection surface.
Claim 2
Dependent Claim
139 words
A reader printer comprising: a focusing lens for focusing light rays passing therethrough: first optical means for directing light rays passing through said focusing lens to a movable recording medium, said first optical means including a rotatable first mirror; drive means for rotating said first mirror from a first angled state to a second angled state at a constant speed during movement of the recording medium; second optical means for directing light rays reflected from said first mirror toward a screen, said second optical means including a second mirror movable between an inserted position wherein it is inserted in a reflection optical path formed by reflection from said first mirror and a retracted position wherein it is retracted from the reflection optical path; and means for moving said second mirror in a direction substantially parallel to its reflection surface.
Claim 3
Dependent Claim
149 words
A reader printer comprising: a focusing lens for focusing light rays passing therethrough; first optical means for directing light rays passing through said focusing lens to a predetermined location for exposure of a recording medium movable along the location, said first optical means including a rotatable first mirror; drive means for rotating said first mirror from a first angled state to a second angled state in synchronism with the velocity of travel of the recording medium; second optical means for directing light rays reflected from said first mirror toward a screen, said second optical means including a second mirror movable between an inserted position wherein it is inserted in a reflection optical path formed by reflection from said first mirror and a retracted position wherein it is retracted from the reflection optical path; and means for moving said second mirror in a direction substantially parallel to its reflection surface.
Claim 4
Dependent Claim
149 words
A reader printer comprising: a focusing lens for focusing light rays passing therethrough; first optical means for directing light rays passing through said focusing lens to a predetermined location for exposure of a recording medium movable along the location, said first optical means including a rotatable first mirror; drive means for rotating said first mirror from a first angled state to a second angled state in synchronism with the velocity of travel of the recording medium; second optical means for directing light rays reflected from said first mirror toward a screen, said second optical means including a second mirror movable between an inserted position wherein it is inserted in a reflection optical path formed by reflection from said first mirror and a retracted position wherein it is retracted from the reflection optical path; and means for moving said second mirror in a direction substantially parallel to its reflection surface.
Claim 5
Dependent Claim
36 words
A reader printer according to claim 1, wherein, when said second mirror is inserted into the reflection optical path formed by reflection from said first mirror, said first mirror is positioned in the first angled state,
Claim 6
Dependent Claim
62 words
A reader printer according to claim 3, wherein, when said second mirror is retracted from the reflection optical path formed by reflection from said first mirror, said first mirror is rotated from the first angled state to the second angled state, so that light rays reflected from said first mirror during its rotation are projected to the recording medium for exposure thereof.
Claim 7
Dependent Claim
122 words
A reader printer comprising: a focusing lens for focusing light rays passing therethrough; a mirror for reflecting light rays passing through said focusing lens; first optical means for directing light rays reflected from said mirror onto a screen; second optical means for directing light rays reflected from said mirror to a predetermined location for exposure; first device means for rotating said mirror about a first axis so as to reflect light rays passing through said focusing lens toward one of said first optical means and said second optical means; and second drive means for rotating said mirror about a second axis different from the first axis so as to scan light rays reflected from said mirror on said predetermined location for exposure.
Claim 8
Dependent Claim
122 words
A reader printer comprising: a focusing lens for focusing light rays passing therethrough; a mirror for reflecting light rays passing through said focusing lens; first optical means for directing light rays reflected from said mirror onto a screen; second optical means for directing light rays reflected from said mirror to a predetermined location for exposure; first device means for rotating said mirror about a first axis so as to reflect light rays passing through said focusing lens toward one of said first optical means and said second optical means; and second drive means for rotating said mirror about a second axis different from the first axis so as to scan light rays reflected from said mirror on said predetermined location for exposure.
Claim 9
Dependent Claim
29 words
A reader printer according to claim 5, wherein the first axis is parallel to the optical axis of said focusing lens while said second axis intersects the optical axis.
Claim 10
Dependent Claim
60 words
A reader printer according to claim 5, wherein said mirror is rotated about the first axis between a first angled state and a second angled state, and said mirror reflects light rays toward said first optical means when assuming the first angled state while, when assuming the second angled state, said mirror reflects light rays toward said second optical means.
Claim 11
Dependent Claim
37 words
A reader printer according to claim 5, wherein a recording medium is movable along the location for exposure, and said second drive means rotates said mirror in synchronization with the speed of travel of the recording medium.
Claim 12
Dependent Claim
62 words
A reader printer according to claim 7, wherein said mirror is rotated about the second axis between a third angled state and a fourth angled state, said mirror being maintained in the third angled state when assuming the first angled state while, when assuming the second angled state, said mirror is rotated from the third angled state to the fourth angled state.
Claim 13
Dependent Claim
32 words
A reader printer according to claim 5, wherein said first drive means supports said mirror and includes support means rotatable about the first axis and a motor for rotating said support means.
Claim 14
Dependent Claim
26 words
A reader printer according to claim 10, wherein said first drive means is disposed on said support means for rotation in unison with said support means.
