Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
90 words
A recording apparatus, comprising: a recording head for effecting an recording operation on a recording material while it is being moved; a plurality of detecting means for detecting plural conditions of said apparatus; control means for effecting the recording operation in accordance with the conditions detected by said detecting means; said plurality of detecting means includes a detecting element movable together with said recording head and a plurality of members to be detected corresponding to the conditions of the apparatus and disposed along a movement path of said detecting element.
Claim 2
Dependent Claim
43 words
An apparatus according to Claim 1, wherein at least one of the members to be detected is movable toward and away from the movement path corresponding to the condition to which said at least one of the members to be detected is associated.
Claim 3
Dependent Claim
20 words
An apparatus according to Claim 1, wherein said detecting element is for detecting a reference position of said recording head.
Claim 4
Dependent Claim
19 words
An apparatus according to Claim 1, wherein said detecting element is for detecting a width of the recording material.
Claim 5
Dependent Claim
145 words
A recording apparatus, comprising a recording head: a carriage for carrying the recording head, wherein a recording operation is effected on a recording material while said carriage is being moved along the recording material; a driving source for feeding the recording material in a direction perpendicular to a movement direction of said carriage; plural gears to be driven by said driving source and arranged in parallel with the movement direction of said carriage; a gear member engageable with selective one of said gears, corresponding to a position of said carriage outside a recording region of said carriage; wherein when said gear member is in meshing engagement with one of said plural gears, the recording material can be fed, and when said gear member is in meshing engagement with another one of said gears, an operation other than the recording material feeding operation can be effected.
Claim 6
Dependent Claim
80 words
A recording apparatus according to Claim 5, wherein said recording head ejects a liquid droplet by a bubble formed by thermal energy produced by an electrothermal transducer, wherein the operation other than the recording material feed operation is to temporarily moving the carriage to a position where the recording head is faced to capping means, and wherein the electrothermal transducer is supplied with an electric signal to cause the recording head to preliminary eject the liquid to the capping means.
Claim 7
Dependent Claim
114 words
An apparatus according to Claim 5, further comprising a plurality of detecting means for detecting plural conditions of said apparatus; control means for effecting the recording operation in accordance with the conditions detected by said detecting means; said plurality of detecting means includes a detecting element movable together with said recording head and a plurality of members to be detected corresponding to the conditions of the apparatus and disposed along a movement path of said detecting element, wherein at least one of the members to be detected is movable toward and away from the movement path corresponding to the condition to which said at least one of the members to be detected is associated.
Claim 8
Dependent Claim
58 words
A container detachably mountable to a recording apparatus of Claim 7, comprising: a member to be detected moved toward the moving path in response to mounting of said container into said apparatus; and a control member for controlling said member to be detected to be out of the movement path when the container is not in said apparatus.
Claim 9
Dependent Claim
136 words
An ink cassette detachably mountable in a recording apparatus, comprising: a member to be detected movable toward and away from a movement path of a detecting element mounted on a carriage for carrying a recording head supplied with ink from said ink cassette; an actuator for moving said member to be detected into the movement path when said ink cassette is mounted in said recording apparatus and for retracting said member to be detected away from the movement path when said ink cassette is detached from said apparatus, said actuator being actable on said recording apparatus; a stopper engageable with said recording apparatus for preventing said ink cassette from being inserted beyond a properly mounted position, wherein said stopper is effective to stop said member to be detected at a predetermined position in the movement path.
Claim 10
Dependent Claim
73 words
An ink jet recording apparatus, comprising: an ink supply member insertable into an ink cartridge; a protection member for protecting said ink supply member, said supply member being movable; discrimination circuit for discriminating mounting of said ink cartridge; wherein said protection member is movable to open said ink supply member by mounting of said ink cartridge, and wherein said protection member functions as a switching member to which said discrimination circuit is responsive.
Claim 11
Dependent Claim
150 words
An apparatus according to Claim 10, further comprising a recording head including a carriage for carrying the recording head, wherein a recording operation is effected on a recording material while said carriage is being moved along the recording material; a driving source for feeding the recording material in a direction perpendicular to a movement direction of said carriage; plural gears to be driven by said driving source and arranged in parallel with the movement direction of said carriage; a gear member engageable with selective one of said gears, corresponding to a position of said carriage outside a recording region of said carriage; wherein when said gear member is in meshing engagement with one of said plural gears, the recording material can be fed, and when said gear member is in meshing engagement with another one of said gears, an operation other than the recording material feeding operation can be effected.
