Printing apparatus and printing method for use with rolled sheet and cut sheet feeding units
First Claim
1. A printing apparatus for performing recording on a recording medium using a recording head, comprising:
- a sheet feeding unit fitting section for fitting one of plural kinds of sheet feeding units, said plural kinds of sheet feeding units including a roll-shaped sheet feeding unit for feeding a continuous rolled sheet and a cut sheet feeding unit for feeding a cut sheet of predetermined size;
means for detecting whether the recording medium fed from the sheet feeding unit fitted to said sheet feeding unit fitting section reaches a predetermined position, said detecting means including an optical sensor; and
recording controlling means for controlling recording by said recording head on the recording medium, which is fed by said sheet feeding unit,wherein said recording controlling means controls recording on the rolled sheet with said optical sensor detecting preprinted marks periodically placed on the rolled sheet and determining a position on the rolled sheet where printing is started when said roll-shaped sheet feeding unit is fitted, wherein said recording controlling means controls recording on the cut sheet with said optical sensor detecting an edge of the cut sheet and determining a position on the cut sheet where printing is started when said cut sheet feeding unit is fitted, and wherein detection of the preprinted marks on the rolled sheet and detection of the edge of the cut sheet are carried out by said optical sensor in different sensing conditions.

Abstract
A printing apparatus is capable of freely selecting a plurality of sheet feeding units each having a different controlling method. It is discriminated as to which one among plural kinds of sheet feeding units is fitted, and printing and a motor for a sheet feeding-unit are controlled based on the result of the discrimination from an output from a sensor disposed on the sheet feeding unit. Especially, in the case that a roll shaped paper feeding unit is fitted, it is judged that a printing medium reaches the position where printing can be started when a TOF sensor detects black color, and in the case that a cut sheet feeding unit is fitted, it is judged that the recording medium reaches the position where printing can be started when the TOF sensor detects white color.

17. A printing method for a printer having a sheet feeding unit fitting section for fitting one of plural kinds of sheet feeding units, the plural kinds of sheet feeding units including a rolled sheet feeding unit for feeding a rolled sheet and a cut sheet feeding unit for feeding a cut sheet and performing recording on a recording medium fed by the sheet feeding unit fitted to the sheet feeding unit fitting section with a recording head, said method comprising the steps of:
-
discriminating which of the plural kinds of sheet feeding units is fitted to the sheet feeding unit fitting section; detecting with detecting means including an optical sensor whether the recording medium fed from the sheet feeding unit fitted to the sheet feeding unit fitting section reaches a predetermined position; and controlling recording with the recording head on the recording medium fed by the discriminated sheet feeding unit, wherein said controlling step controls recording on the rolled sheet with the optical sensor detecting preprinted marks periodically placed on the rolled sheet and determining a position on the rolled sheet where printing is started when the roll-shaped sheet feeding unit is fitted, wherein said recording controlling step controls recording on the cut sheet with the optical sensor detecting an edge of the cut sheet and determining a position on the cut sheet where printing is started when the cut sheet feeding unit is fitted, and wherein detection of the preprinted marks on the rolled sheet and detection of the edge of the cut sheet are carried out by the optical sensor in different sensing conditions. - View Dependent Claims (21, 22, 23, 24, 25, 26)
