Abstract

Abstract A recording apparatus using a recording head driven in accordance with print information includes a feeder for feeding a recording material; a discriminator for discriminating presence or absence of next printing information before completion of discharging of a current printed recording material; and a controller for controlling the feeder to start feeding of the next recording material prior to completion of the discharging of the current recording material, when the discriminator discriminates the presence of the next printing information.

A recording apparatus using a recording head driven in accordance with print information, comprising: feeding means for feeding a recording material; discriminating means for discriminating a presence or absence of next printing information before completion of discharging of a current printed recording material; and control means for controlling said feeding means to start feeding of the next recording material prior to completion of the discharging of the current recording material, when said discriminating means discriminates the presence of the next printing information.
Claim 2
Dependent Claim 82 words
A recording apparatus using a recording head driven in accordance with print information, comprising: feeding means for feeding a recording material; discriminating means for discriminating a presence or absence of next printing information before completion of discharging of a current printed recording material; and control means for controlling said feeding means to start feeding of the next recording material prior to completion of the discharging of the current recording material, when said discriminating means discriminates the presence of the next printing information.
Claim 3
Dependent Claim 29 words
An apparatus according to claim 1, wherein said discriminating means conducts a discriminating operation after start of discharging of the current recording material and before completion of the discharging.
Claim 4
Dependent Claim 25 words
An apparatus according to claim 1, wherein said discriminating means conducts a discriminating operation prior to start of discharging operation of the current recording material.
Claim 5
Dependent Claim 34 words
An apparatus according to claim 1, 2 or 3, wherein said control means controls said feeding means to start feeding of the next recording material prior to completion of discharging of the recording material.
Claim 6
Independent Claim 66 words
An apparatus according to any one of claims 1-3 wherein said recording head has an ejection outlet through which a droplet of ink is ejected, an ink passage in communication with said ejection outlet and an energy generating element for producing energy contributable to eject a droplet of ink through the ejection outlet by change of state of the ink produced when driven by printing information.
Claim 7
Dependent Claim 30 words
An apparatus according to claim 5, wherein, said energy generating element generates sufficient thermal energy to produce a bubble to eject a droplet of the ink through said ejection outlet.
Claim 8
Dependent Claim 137 words
A recording apparatus using a recording head driven by print information, comprising: storing means for temporarily storing at least one scan print information in at least a main scan direction; feeding means for feeding a recording material in a sub-scan direction or each main scan operation. detecting means for detecting an edge of the recording material upstream of a recording position in the sub-scan direction; discriminating means for discriminating a presence or absence of the print information in said storing means at a point in time when the recording material is fed through a predetermined distance after detection of an edge of the recording material by said detecting means; and control means for controlling said feeding means to feed the next recording material to said recording position when said discriminating means discriminates presence of the print information.
Claim 9
Dependent Claim 137 words
A recording apparatus using a recording head driven by print information, comprising: storing means for temporarily storing at least one scan print information in at least a main scan direction; feeding means for feeding a recording material in a sub-scan direction or each main scan operation. detecting means for detecting an edge of the recording material upstream of a recording position in the sub-scan direction; discriminating means for discriminating a presence or absence of the print information in said storing means at a point in time when the recording material is fed through a predetermined distance after detection of an edge of the recording material by said detecting means; and control means for controlling said feeding means to feed the next recording material to said recording position when said discriminating means discriminates presence of the print information.
Claim 10
Dependent Claim 18 words
An apparatus according to claim 7, wherein said detecting means detects a trailing edge of the recording material.
Claim 11
Dependent Claim 32 words
An apparatus according to claim 8, wherein said predetermined distance corresponds to a remaining recordable width on the recording material when said detecting means detects the trailing edge of the recording material.
Claim 12
Dependent Claim 19 words
An apparatus according to claim 7, wherein said storing means is capable of storing print information for N scans.
Claim 13
Dependent Claim 43 words
An apparatus according to claim 10, wherein the predetermined distance corresponds to a difference between a remaining recordable width on the recording material when said detecting means detects the trailing edge of the recording material and a movement distance corresponding to (N-1) scans.
Claim 14
Independent Claim 66 words
An apparatus according to any one of claims 7-11, wherein said recording head has an ejection outlet through which a droplet of ink is ejected, an ink passage in communication with said ejection outlet and an energy generating element for producing energy contributable to eject a droplet of ink through the ejection outlet by change of state of the ink produced when driven by printing information.
Claim 15
Dependent Claim 30 words
An apparatus according to claim 12, wherein said energy generating element generates sufficient thermal energy to produce a bubble to eject a droplet of the ink through said ejection outlet.
Claim 16
Dependent Claim 151 words
A recording apparatus using a recording head driven in accordance with print information, comprising: storing means for temporarily storing record information for at least one scan until a recording operation is completed; accommodating means for accommodating recording materials; detecting means disposed between said accommodating means and a recording position where recording is effected on the recording material, for detecting a presence or absence of a recording material at a position L1 away from the recording position toward upstream with respect to a sub-scan direction; discriminating means for discriminating a presence or absence of the record information in said storing means at a point in time when the recording material is fed through a predetermined distance L(≧L1) after said detecting means detects a trailing edge of the recording material; feeding means for feeding a next recording material to the recording position when said discriminating means discriminates the presence of the record information.
Claim 17
Dependent Claim 151 words
A recording apparatus using a recording head driven in accordance with print information, comprising: storing means for temporarily storing record information for at least one scan until a recording operation is completed; accommodating means for accommodating recording materials; detecting means disposed between said accommodating means and a recording position where recording is effected on the recording material, for detecting a presence or absence of a recording material at a position L1 away from the recording position toward upstream with respect to a sub-scan direction; discriminating means for discriminating a presence or absence of the record information in said storing means at a point in time when the recording material is fed through a predetermined distance L(≧L1) after said detecting means detects a trailing edge of the recording material; feeding means for feeding a next recording material to the recording position when said discriminating means discriminates the presence of the record information.
Claim 18
Dependent Claim 178 words
