Abstract
Abstract A thermal transfer recording apparatus for transferring an ink of an ink sheet onto a recording medium to record an image on the recording medium, includes an ink sheet convey unit for conveying the ink sheet, a recording medium convey unit for conveying the recording medium, a recording unit which is driven in correspondence with image data and records an image on the recording medium using the ink sheet, and a control unit for, when a next recording operation is not instructed after image recording by the recording unit, driving the recording unit with an energy lower than that in a normal image recording mode, and for, when a time interval until the next recording operation becomes equal to or longer than a predetermined period of time after the above driving operation, driving the recording unit with an energy lower than that in the normal image recording mode at a predetermined time interval.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
161 words
A thermal transfer recording apparatus for transferring an ink of an ink sheet onto a recording medium to record an image on said recording medium, comprising: ink sheet conveying means for conveying said ink sheet; recording medium conveying means for conveying said recording medium; recording means for recording said image on said recording medium using said ink sheet; and first drive control means for driving and controlling said recording means in an auxiliary manner to generate heat at a temperature insufficient to cause said recording means to record at a predetermined interval repeatedly between termination of a current image recording operation and commencement of a next image recording operation, wherein said first drive control means counts a time passed after said recording means is driven in said auxiliary manner and a next auxiliary driving of said recording means is performed by counting a predetermined time ΔT n (n>1), and wherein said predetermined time satisfies a relationship ΔT n <ΔT n+1 .
Claim 2
Dependent Claim
161 words
A thermal transfer recording apparatus for transferring an ink of an ink sheet onto a recording medium to record an image on said recording medium, comprising: ink sheet conveying means for conveying said ink sheet; recording medium conveying means for conveying said recording medium; recording means for recording said image on said recording medium using said ink sheet; and first drive control means for driving and controlling said recording means in an auxiliary manner to generate heat at a temperature insufficient to cause said recording means to record at a predetermined interval repeatedly between termination of a current image recording operation and commencement of a next image recording operation, wherein said first drive control means counts a time passed after said recording means is driven in said auxiliary manner and a next auxiliary driving of said recording means is performed by counting a predetermined time ΔT n (n>1), and wherein said predetermined time satisfies a relationship ΔT n <ΔT n+1 .
Claim 3
Dependent Claim
59 words
An apparatus according to claim 1, further comprising second drive control means for controlling said recording means to generate heat after said first drive control means drives said recording means and before said next image recording operation in response to a non-recording period from termination of said first image recording operation to commencement of said next image recording operation.
Claim 4
Dependent Claim
68 words
An apparatus according to claim 2, wherein said second control means drives said recording means to generate heat immediately before said next image recording operation when said non-recording period exceeds a first predetermined time period and said second control means does not drive said recording means to generate heat immediately before said next image recording operation when said non-recording period is less than a second predetermined time period.
Claim 5
Dependent Claim
24 words
An apparatus according to claim 1, wherein a conveying direction of said ink sheet is opposite to a conveying direction of said recording medium.
Claim 6
Dependent Claim
24 words
An apparatus according to claim 1, wherein a conveying speed of said ink sheet is lower than a conveying speed of said recording medium.
Claim 7
Dependent Claim
26 words
An apparatus according to claim 1, wherein said recording means comprises a thermal head having a plurality of heat generating elements heated in units of blocks.
Claim 8
Dependent Claim
21 words
An apparatus according to claim 6, wherein said plurality of heat generating elements correspond to a width of said recording medium.
Claim 9
Dependent Claim
50 words
An apparatus according to claim 1, further comprising receiving means for receiving a transmitted image data and decoding means for decoding said transmitted image data received by said receiving means to obtain a decoded image data, wherein said recording means records said image in response to said decoded image data.
Claim 10
Dependent Claim
24 words
An apparatus according to claim 8, wherein a conveying direction of said ink sheet is opposite to a conveying direction of said recording medium.
Claim 11
Dependent Claim
24 words
An apparatus according to claim 8, wherein a conveying speed of said ink sheet is lower than a conveying speed of said recording medium.
Claim 12
Dependent Claim
26 words
An apparatus according to claim 8, wherein said recording means comprises a thermal head having a plurality of heat generating elements heated in units of blocks.
Claim 13
Dependent Claim
21 words
An apparatus according to claim 11, wherein said plurality of heat generating elements correspond to a width of said recording medium.
