Recorder-medium registration system

Claim 2

Printing apparatus operable for feeding a recording medium, comprising: recording means disposed at a recording station for performing repeated recording operations on the recording medium to record, in parallel and in the same recording operation, description information and a separate control mark on the recording medium; feed means for feeding the recording medium to said recording station before a recording operation; detection means for detecting, before a recording operation, the control mark recorded on the recording medium by said recording means in a previous recording operation; and control means for controlling said feed means in response to the output of said detection means to properly position the recording medium at said recording station before the next recording operation.

Claim 3

Printing apparatus according to claim 1, wherein said recording means records the control marks at a plurality of positions on the recording medium and the appparatus further comprises a plurality of detection means.

Claim 4

Printing apparatus according to claim 2, wherein said plural detection means are arranged at left and right ends of the recording medium.

Claim 5

Printing apparatus according to claim 1, wherein said feed means includes a pulse motor.

Claim 6

Printing apparatus according to claim 1, wherein said detection means includes a light emitting diode and a photo-transistor.

Claim 7

Printing apparatus according to claim 4, further comprising a pulse count setting circuit for setting the number of pulses issued by said motor representing the normal range.

Claim 8

Printing apparatus according to claim 1, wherein said recording means scans the recording medium during a recording operation and records a control mark and the description information in a scan.

Claim 9

Printing apparatus according to claim 1, wherein said recording means records the control mark at the start of a scan of said recording means.

Claim 10

Printing apparatus according to claim 1, further comprising converting means for converting a feed distance of the recording medium to a number of pulses, wherein said control means controls said feed means by determining whether or not the number of pulses representing the feed distance of the recording medium is within a normal range based on the output of said detection means.

Claim 11

Printing apparatus operable for feeding a record medium, comprising: feed means for feed the record medium in a feed direction; recording means disposed at a recording station for performing repeated recording operations on the record medium to record, in parallel and in the same recording operation, image information and a separate detectable mark after the record medium is fed to said recording station by said feed means; first detection means for detecting the position of the edges of the record medium transverse to the feed direction; second detection means for detecting, before a recording operation, the position relative to the feed direction of the detectable mark recorded on the record medium in a previous recording operation; and control means for controlling said feed means by determining from the ouput of said first detection means the position shift of the record medium in the transverse direction and for determining from the output of said second detection means the position shift of the record medium in the feed direction in order to properly position the record medium at said recording station before the next recording operation.

Claim 12

Printing apparatus operable for feeding a record medium, comprising: feed means for feed the record medium in a feed direction; recording means disposed at a recording station for performing repeated recording operations on the record medium to record, in parallel and in the same recording operation, image information and a separate detectable mark after the record medium is fed to said recording station by said feed means; first detection means for detecting the position of the edges of the record medium transverse to the feed direction; second detection means for detecting, before a recording operation, the position relative to the feed direction of the detectable mark recorded on the record medium in a previous recording operation; and control means for controlling said feed means by determining from the ouput of said first detection means the position shift of the record medium in the transverse direction and for determining from the output of said second detection means the position shift of the record medium in the feed direction in order to properly position the record medium at said recording station before the next recording operation.

Claim 13

Printing apparatus according to claim 10, wherein said recording means scans the record medium during a recording operation and records a detectable mark and image information in a scan.

Claim 14

Printing apparatus according to claim 10, wherein said recording means records the detectable mark at the start of a scan of said recording means.

Claim 15

Printing apparatus operable for feeding a recording medium, comprising: feed means for feeding the record medium; recording means disposed at a recording station for performing repeated recording operations on the record medium to record, in parallel and in the same recording operation, description information and a separate control pattern after the record medium is fed to said recording station by said feed means; read-out means for reading out, before a recording operation, the control pattern recorded on the record medium by said recording means in a previous recording operation; and control means responsive to the output of said read-out means for controlling said feed means to properly position the record medium at said recording station before the next recording operation.

Claim 16

Printing apparatus operable for feeding a recording medium, comprising: feed means for feeding the record medium; recording means disposed at a recording station for performing repeated recording operations on the record medium to record, in parallel and in the same recording operation, description information and a separate control pattern after the record medium is fed to said recording station by said feed means; read-out means for reading out, before a recording operation, the control pattern recorded on the record medium by said recording means in a previous recording operation; and control means responsive to the output of said read-out means for controlling said feed means to properly position the record medium at said recording station before the next recording operation.

Claim 17

Printing apparatus according to claim 13, wherein said recording means records the control pattern comprising at least one of a group of characters, figures and symbols on the record medium.
