专利汇可以提供Facsimile transmitter and method of assembling the same专利检索，专利查询，专利分析的服务。并且A facsimile transmitter includes a lamp for directing a light beam toward a scanner which reflects the light onto a document to be reproduced, picks up the light reflected from the document and directs such light to a photomultiplier operable to send to a reproducing recorder as electrical signal proportional to the intensity of the light and the shade value of the document. The lamp is accurately pre-located and pre-mounted in a permanent holder which is detachably secured to a lamp housing and which, as an incident to attachment to the housing, automatically locates the lamp in a precisely established position to produce light of maximum intensity, the pre-mounted lamp being located in such position by the holder regardless of dimensional irregularities in the lamp. To focus the light beam on the document accurately and to direct the reflected light along an exact path toward the photomultiplier, the scanner is formed as two initially adjustable telescopic units carrying relatively simple plane mirrors adapted to be adjusted into precisely established positions by sliding and rotating the units and thereafter held permanently in such positions by bonding the units rigidly together.，下面是Facsimile transmitter and method of assembling the same专利的具体信息内容。

权利要求

1. In a facsimile transmitter scanner adapted to be moved across a document to be reproduced, the combination of, a first member formed with an axially extending bore opening ouT of one end of said member, a hole in one wall of said member and opening into said bore, a reflector positioned in said bore for receiving light directed into said one end of the bore and for reflecting such light through said hole and onto the document, a second member positioned adjacent said first member and formed with a second axially extending bore opening out of at least one end of said second member with the open end of the second bore facing oppositely of the open end of the first bore, a second hole in one wall of said second member and opening into said second bore, a second reflector positioned in said second bore for receiving light reflected off of the document into said second hole and for reflecting such light out of said one end of said second bore, said members being sized and shaped for telescoping together with a slidable and rotatable fit to enable location of said reflectors in precisely established axial and angular positions relative to one another, and means bonding said members rigidly to one another after said reflectors have been located in said positions thereby to prevent further sliding and rotation of one member relative to the other and to hold said reflectors permanently in said positions.

2. A facsimile transmitter scanner as defined in claim 1 in which the bore in one of said members extends completely through such member and receives the other member when the two members are telescoped together.

3. A facsimile transmitter scanner as defined in claim 1 in which said means comprises a quantity of hardened cement between said members and bonding the latter together rigidly.

4. A facsimile transmitter scanner as defined in claim 1 in which said reflectors comprise plane mirrors fastened to said member and inclined oppositely relative to one another.

5. In a facsimile transmitter scanner adapted to be moved across a document to be reproduced, the combination of, inner and outer members each having inboard and outboard ends and each being formed with an axially extending bore opening out of the outboard end of the respective member, an opening formed in the inboard end of said outer member and sized and shaped to telescopically receive the inboard end of said inner member with a slidable and rotatable fit, means bonding said members together rigidly to prevent relative sliding and rotation of said members, a hole formed in one wall of said inner member near the inboard end thereof and opening into the bore in said inner member, hole means in one wall of said outer member and alined with said hole in said inner member, said hole means also opening into the bore in said outer member, a transparent window carried by said outer member and covering said hole means, and a reflector positioned in the bore of each member with one of the reflectors located to reflect light received through the outboard end of one of said members onto said document through said hole means and said window and with the other of said reflectors located to direct to the outboard end of the other of said members the light reflected from said document and through said hole means and said window.

6. A facsimile transmitter scanner as defined in claim 5 in which said means comprises a quantity of hardened cement between said members for bonding said members rigidly together and for establishing a gas-tight seal between said members.

7. A facsimile transmitter scanner as defined in claim 6 further including a lens positioned within the outboard end of the bore in each member in gas-tight sealing relation with the member, means establishing a gas-tight seal between said window and said outer member, and a charge of inert gas in each of said bores to prevent moisture from condensing on said window, said reflectors and said lenses.

8. A facsimile transmitter scanner as defined in claim 7 further including a passage establishing fluid communication between said bores to permit flow of said gas from one bore to the other.

9. In a facsimile transmitter, the combination of, a frame for supporting a document to be copied; a lamp positioned on said frame to direct rays of light along a predetermined path across the document; a scanner mounted on said frame and movable across the document in said path; said scanner comprising a first member formed with an axially extending bore opening out of one end of said member and alined with said path, a hole in one wall of said member and opening into said bore, a reflector positioned in said bore for receiving light directed along said path into said one end of the bore and for reflecting such light through said hole and onto the document, a second member telescoped with said first member with a slidable and rotatable fit, means bonding said members together rigidly to prevent relative sliding and rotation of said members, said second member being formed with a second axially extending bore opening out of at least one end of said second member with the open end of the second bore facing oppositely of the open end of the first bore and being alined with said path, a second hole in one wall of said second member and opening into said second bore, a second reflector positioned in said second bore for receiving light reflected off of the document into said second hole and for reflecting such light out of said one end of said second bore; and a light-to-signal transducer mounted on said frame to receive the light directed out of said second bore and operable to produce an electrical signal varying in accordance with changes in the intensity of such light.
