Continuous sheet processing apparatus and continous sheet processing method

Abstract

A processing portion ( 3 ) is arranged in a position above and on a lateral side (right side in the drawing) of a roll body accommodating portion ( 2 ), and an engagement portion ( 11 a ) of a guide plate ( 11 ), which is positioned between the roll body accommodating portion ( 2 ) and the processing portion ( 3 ), engaging with a continuous sheet ( 1 ) is positioned while being biased to an opposite side (left side in the drawing) of the processing portion ( 3 ) with respect to a position directly above a central axis of a roll body ( 1 a ), or preferably to an opposite side (left side in the drawing) of the processing portion ( 3 ) with respect to an outermost end of the roll body ( 1 a ). The engagement portion ( 11 a ) of the guide plate ( 11 ) engages with the continuous sheet ( 1 ), thereby allowing the continuous sheet ( 1 ) to be once guided to the opposite side (left side in the drawing) of the processing portion ( 3 ) with respect to straight lines (L 1 ) and (L 2 ) each connecting a drawing out portion of the roll body ( 1 a ) and the processing portion ( 3 ) to then be guided to the processing portion ( 3 ).

1 . A continuous sheet processing apparatus, comprising:
 a roll body accommodating portion for accommodating a roll body formed of a wound continuous sheet;   a processing portion, which is arranged in a position above the roll body accommodating portion and horizontally shifted from a position directly above a central axis of the roll body accommodated in the roll body accommodating portion, for performing a processing with respect to the continuous sheet drawn out from the roll body; and   a guide member, which is positioned between the roll body accommodating portion and the processing portion, for guiding the continuous sheet drawn out from the roll body,   wherein the guide member has an engagement portion engaging with the continuous sheet drawn out from the roll body and is arranged so that at least a part of the engagement portion is positioned in a position above the roll body accommodated in the roll body accommodating portion and on an opposite side of the processing portion with respect to the central axis of the roll body.   
   
   
       2 . A continuous sheet processing apparatus according to  claim 1 , wherein the engagement portion is arranged in such a position that the engagement portion once guides the continuous sheet drawn out from the roll body accommodated in the roll body accommodating portion to an opposite side of the processing portion with respect to a straight line connecting a drawing out portion of the roll body and the processing portion. 
   
   
       3 . A continuous sheet processing apparatus according to  claim 1 , wherein the engagement portion is positioned while being biased to an opposite side of the processing portion with respect to an outermost end of the roll body accommodated in the roll body accommodating portion. 
   
   
       4 . A continuous sheet processing apparatus according to  claim 1 , further comprising a cutter portion positioned on a downstream side of the processing portion and capable of cutting the continuous sheet drawn out from the roll body. 
   
   
       5 . A continuous sheet processing apparatus according to  claim 1 , wherein the processing portion comprises: a processing head for performing the processing with respect to the continuous sheet drawn out from the roll body; and a platen roller, which is opposed to the processing head, for transporting the continuous sheet. 
   
   
       6 . A continuous sheet processing apparatus according to  claim 1 , wherein the processing portion comprises a printing portion for performing printing on the continuous sheet drawn out from the roll body. 
   
   
       7 . A continuous sheet processing apparatus according to  claim 1 , wherein the processing portion comprises a thermal activation portion for heating and thermally activating the continuous sheet drawn out from the roll body. 
   
   
       8 . A continuous sheet processing method comprising the steps of:
 drawing out a continuous sheet from a roll body accommodated in a roll body accommodating portion;   guiding the continuous sheet to the processing portion arranged in a position above the roll body accommodating portion and horizontally shifted from a position directly above a central axis of the roll body accommodated in the roll body accommodating portion; and   performing a processing with respect to the continuous sheet by the processing portion, wherein   the continuous sheet drawn out from the roll body accommodated in the roll body accommodating portion is transported so that the continuous sheet is once guided by an engagement portion of a guide member, positioned between the roll body accommodating portion and the processing portion, to an opposite side of the processing portion with respect to a straight line connecting a drawing out portion of the roll body and the processing portion, and is then guided to the processing portion.   
   
   
       9 . A continuous sheet processing method according to  claim 8 , further comprising the step of being cut off the continuous sheet, which has been subjected to the processing by the processing portion, by a cutter portion positioned on a downstream side of the processing portion. 
   
   
       10 . A continuous sheet processing method according to  claim 8 , wherein printing is performed by the processing portion on the continuous sheet drawn out from the roll body. 
   
   
       11 . A continuous sheet processing method according to  claim 8 , wherein the continuous sheet drawn out from the roll body is heated and thermally activated by the processing portion.
