Abstract
Abstract There is disclosed a facsimile apparatus equipped with an ink jet printing unit, capable of reducing the number of ink discharge recovery operations of the ink jet recording head, thereby reducing the ink consumption. The received image is stored in an image memory, with inspection for errors in transmission in an error correction mode, and is collectively printed after a predetermined amount of image data is stored. The recording head is uncapped by a protocol signal transmitted after the image data.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
144 words
An image communicating apparatus comprising: communication means for effecting communication of a procedure signal relating to the communication and image data; recording means for discharging ink toward a recording material in accordance with image data received by said communication means; capping means for capping said recording means; memory means for storing said image data; communication control means for controlling said memory means so as to store, in said memory means, image data transmitted from a transmitting unit; first control means for identifying the procedure signal transmitted in succession to the image data and controlling said capping means based on a result of the identification to separate a cap from the recording means; and second control means for controlling said recording means so as to record the image data stored in said memory means, after the separation of the cap by said first control means.
Claim 2
Dependent Claim
35 words
An apparatus according to claim 1, wherein said first control means is adapted to control said capping means to cap said recording means after the recording of the image data stored in said memory means.
Claim 3
Dependent Claim
48 words
An apparatus according to claim 1 or 2, wherein said communication control means is adapted to inspect the received image data for an error in every predetermined amount thereof, and, in the presence of an error in the transmission, releases a request for re-sending of said image data.
Claim 4
Dependent Claim
24 words
An apparatus according to claim 3, wherein said communication control means is adapted to inspect the error in transmission, by half-doubled or full-doubled communication.
Claim 5
Dependent Claim
40 words
An apparatus according to claim 3 or 4, comprising plural memory means, wherein, in the course of collective printing of the image data stored in one of said plural memory means, the received data are stored in another memory means.
Claim 6
Dependent Claim
56 words
An apparatus according to claim 5, wherein, if image data of a predetermined amount are not stored in said another memory means at the completion of collective printing of the image data stored in the first-mentioned memory means, said first control means is adapted to control said capping means so as to cap said recording means.
Claim 7
Dependent Claim
73 words
An apparatus according to claim 1, wherein, in the transmission of image data of a predetermined amount, said first control means is adapted to identify either the protocol signal transmitted at the end of transmission of image data of a page or the protocol signal transmitted at the end of transmission of image data of all pages and to control said capping means in order to separate the cap from said recording means.
Claim 8
Independent Claim
58 words
An apparatus according to either one of claims 1 to 7, wherein said recording means comprises plural discharge openings for discharging ink, and thermal energy generating means respectively provided for said discharge openings and adapted to induce a thermal state change in the ink thereby discharging the ink from the discharge opening and forming a flying liquid droplet.
Claim 9
Dependent Claim
18 words
An apparatus according to claim 8, wherein said state change involves formation of a bubble by membrane boiling.
Claim 10
Dependent Claim
165 words
An image communicating apparatus comprising: communication means for effecting communication of a procedure signal relating to the communication and image data; recording means for discharging ink towards a recording material in accordance with the image data received by said communication means; recovery means for effecting a discharge recovery treatment on said recording means; memory means for storing the image data; communication control means for controlling said memory means so as to store, in said memory means, the image data transmitted from a transmitting unit, said communication control means being adapted to inspect the transmitted data for an error and to request the re-sending of the image data including the error; recovery control means for identifying the procedure signal transmitted in succession to said image data and controlling said recovery means based on a result of the identification; and recording control means for controlling said recording means so as to record the image data stored in said memory means after the function of said recovery means.
Claim 11
Dependent Claim
44 words
An apparatus according to claim 10, wherein said recovery means comprises capping means for capping said recording means, and said recovery control means is adapted to control said capping means based on said result of identification to separate a cap from said recording means.
Claim 12
Dependent Claim
35 words
An apparatus according to claim 11, wherein said recovery control means is adapted to control said capping means after the recording of the image data stored in said memory means, thereby capping said recording means.
Claim 13
Independent Claim
61 words
An apparatus according to either one of claims 10 to 12, wherein, at the transmission of image data of a predetermined amount, said recovery control means is adapted to identify the protocol signal received by said communication means at the end of transmission of image data of a page or at the end of transmission of image data of all pages.
Claim 14
Dependent Claim
24 words
An apparatus according to claim 10, wherein said communication control means is adapted to inspect the error in transmission by half-doubled or full-doubled communication.
Claim 15
Independent Claim
58 words
An apparatus according to either one of claims 10 to 14, wherein said recording means comprises plural discharge openings for discharging ink, and thermal energy generating means respectively provided for said discharge openings and adapted to induce a thermal state change in the ink thereby discharging the ink from the discharge opening and forming a flying liquid droplet.
Claim 16
Dependent Claim
18 words
An apparatus according to claim 15, wherein said state change involves formation of a bubble by membrane boiling.
