Abstract
A recording device for recording on a sheet is provided with a heater for heating portions of the sheet on which printing is to be carried out. The heater is controlled by a memory which stores data related to the period of time required to heat the portions of the sheet to a predetermined temperature value as well as the time required to heat a preceding portion of the sheet.
Claims20
A recording device employing a recording sheet, comprising a platen member for supporting said recording sheet, a recording head member provided on a carriage member being movable along said platen member, for executing recording operations on said recording sheet, sheet feed means for feeding said recording sheet by one recording line, and heat means for heating a predetermined portion of said recording sheet, said recording device further comprises:
- memory means for storing data relating to a period of time required for heating said predetermined portion of said recording sheet till a temperature value of said predetermined portion reaches a predetermined value;
- parameter set means for setting a predetermined parameter based upon a period of time having been required for executing recording operations on a certain recording line;
- and
- control means for controlling said sheet feed means so as to be operated in a predetermined manner in accordance with both the data stored in said memory means and the parameter set by said parameter set means.
A recording device employing a recording sheet, comprising a platen member for supporting said recording sheet, a recording head member provided on a carriage member being movable along said platen member, for executing recording operations on said recording sheet, sheet feed means for feeding said recording sheet by one recording line, and heat means for heating at least a portion of said recording sheet corresponding to a recording line on which the recording operations are to be executed and the succeeding recording line, said recording device further comprises:
- memory means for storing data relating to a predetermined period of time required for heating said recording sheet till a temperature value of the portion of said recording sheet corresponding to said succeeding recording line reaches a predetermined value;
- parameter set means for setting a predetermined parameter based upon a period of time having been required for executing recording operations on a certain recording line;
- and
- control means for controlling said sheet feed means so as to be operated in a predetermined manner in accordance with both the data stored in said memory means and the parameter set by said parameter set means.
A recording device employing a recording sheet, comprising a platen member for supporting said recording sheet, a recording head member provided on a carriage member being movable along said platen member, for executing recording operations on said recording sheet, sheet feed means for feeding said recording sheet by one recording line, and heat means for heating a first predetermined portion of said recording sheet, said recording device further comprises:
- first examine means for examining whether a temperature value of said first predetermined portion is larger than a first predetermined value;
- second examine means for examining whether a temperature value of a second predetermined portion of said recording sheet is less than a second predetermined value;
- and
- control means for controlling said sheet feed means so as to feed said recording sheet in case that at least the value examined by said first examine means is larger than said first predetermined value and the value examined by said second examine means is less than said second predetermined value.
