Definitions
- the present invention relates to a continuous sheet processing method and a continuous sheet processing apparatus for performing a processing such as printing or thermal activation with respect to a continuous sheet.
- a continuous sheet processing apparatus in which a continuous sheet is successively drawn out from a roll body to perform a processing such as printing or thermal activation with respect to the continuous sheet which is drawn out and a portion thereof subjected to the processing is performed is cut off, thereby obtaining cut form paper.
- Patent Document 1 As a method of holding the roll body in the continuous sheet processing apparatus as described above, as disclosed in Patent Document 1, there is available a method in which a central shaft (roll shaft) is inserted into a central hole of a roll body and end portions of the central shaft, which laterally protrude from the roll body, are supported by a frame (first related art example) Further, as disclosed in Patent Document 2, there is available a method in which a fitting portion of each of bobbins (holders) provided to a frame is inserted into a central hole of a roll body from a side thereof, for supporting the roll body (second related art example). Further, as disclosed in Patent Documents 3 and 4 , there is also available a method in which a roll body is merely placed on a bottom surface of a roll body accommodating portion (third and fourth related art examples).
- the bobbin is provided to the frame so as not to be removable therefrom. Accordingly, unlike in the first related art example, there is no risk of losing the bobbin by mistake. Further, only by one operation of inserting the bobbin into the central hole of the roll body, the holding of the roll body is completed. Accordingly, the number of operations decreases compared to the first related art example requiring the two operations. However, the operation of inserting the bobbin into the central hole of the roll body in a confined space of the roll body accommodating portion is extremely complicated.
- FIG. 19 An example of the above-mentioned structure is shown in FIG. 19 .
- a processing portion 3 is provided above and on a lateral side of a roll body accommodating portion 2 (position shifted in horizontal direction from position directly above central axis of roll body 1 a accommodated in roll body accommodating portion 2 ).
- a platen roller 5 of the processing portion 3 is rotated, thereby allowing the continuous sheet 1 of the roll body 1 a to be successively drawn out to be supplied to the processing portion 3 .
- the roll body 1 a is hardly restricted in a space of the roll body accommodating portion 2 and freely movable therein. Therefore, when the continuous sheet 1 drawn out from the roll body 1 a is transported while being pulled by a platen roller 5 provided to the processing portion 3 , there is such a risk that the roll body 1 a randomly moves in the roll accommodating body 2 by the pulling force.
- the processing portion 3 is positioned above the roll body accommodating portion 2 . Accordingly, at a time of transporting the continuous sheet 1 , there is a fear of the roll body 1 a being lifted up.
- the roll body 1 a does not stably become standstill in a state where the roll body 1 a is lifted up, and performs irregular operations in the roll body accommodating portion 2 .
- the continuous sheet 1 is intermittently transported, when transportation of the continuous sheet 1 is performed (when continuous sheet 1 is pulled up), the roll body 1 a is lifted up, and when transportation of the continuous sheet 1 is not performed (when continuous sheet 1 is not pulled), the roll body 1 a falls down on a bottom surface of the roll body accommodating portion 2 due to the gravity.
- the lifting up and the falling down of the roll body 1 a are repeated as described above, large irregular movements of the roll body 1 a are caused. As a result, the continuous sheet 1 cannot be correctly supplied to the processing portion 3 .
- a sensor 18 for detecting a size of the roll body 1 a, that is, a remaining amount of the sheet by performing detection on a part of the roll body 1 a there may be provided a sensor 18 for detecting a size of the roll body 1 a, that is, a remaining amount of the sheet by performing detection on a part of the roll body 1 a.
- the roll body 1 a performs the irregular operations such as the lifting up of the roll body 1 a as described above in the roll body accommodating portion 2 and the roll body 1 a temporarily gets out of a detection region of the sensor 18 , there is a risk of making misjudgment that the remaining amount of the sheet is small regardless of the size of the roll body 1 a.
- a continuous sheet processing apparatus includes: 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, in which 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.
- the engagement portion be 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.
- the drawing out portion herein means a portion where the continuous sheet comes off from the roll body.
- the guide member exists. Accordingly, there is a possibility of the drawing out portion of the roll body being different in position from that in a case where there is formed a transport path for linearly supplying the continuous sheet from the roll body to the processing portion.
- the engagement portion be arranged in such a position that the engagement portion once guides the continuous sheet to the opposite side of the processing portion with respect to both a straight line connecting the processing portion and the drawing out portion of the roll body in a case where there exists the guide member, and a straight line connecting the processing portion and the drawing out portion of the roll body in a case where there exists no guide member.
- the engagement portion be 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.
- the continuous sheet processing apparatus may include 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.
- the processing portion includes: 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 arranged to oppose the processing head, for transporting the continuous sheet.
- the processing portion may include a printing portion for performing printing on the continuous sheet drawn out from the roll body.
- the processing portion may include a thermal activation portion for heating and thermally activating the continuous sheet drawn out from the roll body.
- the present invention has another characteristic point in that, in a continuous sheet processing method of performing a processing with respect to a continuous sheet by a processing portion by drawing out the continuous sheet from a roll body accommodated in a roll body accommodating portion and 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, 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.
- the continuous sheet which has been subjected to the processing by the processing portion may be cut off by a cutter portion positioned on a downstream side of the processing portion.
- Printing may be performed by the processing portion on the continuous sheet drawn out from the roll body. Further, the continuous sheet drawn out from the roll body may be heated and thermally activated by the processing portion.
- the present invention even in the structure in which the roll body can easily be set only by being put into the roll body accommodating portion, there is not involved the movement such as the lifting up of the roll body at the time of transporting the continuous sheet drawn out from the roll body, thereby enabling favorable transportation thereof.

Both the pair of inclination surfaces 2 a come into line contact (point contact when viewed in sectional view as shown in FIG. 1 ) with the outermost peripheral surface of the roll body la, thereby supporting the roll body 1 a.
- a center of the roll body 1 a accommodated in the roll body accommodating portion 2 and a center of the roll body accommodating portion 2 are positioned on the same straight line. That is, positions of the center of the roll body accommodating portion 2 and the center of the roll body 1 a substantially coincide with each other at least in a width direction (left-and-right direction in FIGS. 1 and 2 ) of the apparatus.

- a spring (not shown) is provided between each of the arms 12 and a part of the cover 8 .
- the arm 12 , the link arm 14 , and the projection portions 8 a and 8 b are provided to each side portion of the cover 8 .
- the guide plate 11 is mounted so as to extend between the first link arms 12 positioned on the both side portions.

- An inner surface of the frame 17 is provided with cams 17 a.
- each of the arms 12 is provided with a protruding portion 12 a.
- the inner surface of the frame 17 is also provided with guide grooves 17 b.
- the transport path for the continuous sheet is formed along a straight line L 1 connecting between a drawing out portion of the roll body 1 a and the processing portion 3 .
- the engagement portion 11 a of the guide plate 11 forms the transport path which guides the continuous sheet 1 to the opposite side of the processing portion 3 (left side in FIGS. 1 and 2 ) once with respect to the straight line L 1 and guides the continuous sheet 1 to the processing portion 3 thereafter.
- a position of the drawing out portion of the roll body 1 a slightly moves, and a straight line L 2 connecting the drawing out portion of the roll body 1 a in this case and the processing portion 3 is slightly different from the straight line L 1 .
- the engagement portion 11 a is arranged so as to guide the continuous sheet 1 to the opposite side of the processing portion 3 (left side in FIGS. 1 and 2 ) once with respect to both the straight line L 1 and the straight line L 2 .
- a panel 19 provided with a display portion, an input portion, and the like is arranged.
- the roll body 1 a is set in the continuous sheet processing apparatus.
- the setting operation may be performed by only inserting the roll body 1 a into a space of the roll body accommodating portion 2 .
- the cover 8 is closed.
- the continuous sheet 1 pulled out from the roll body 1 a is guided to the opposite side of the processing portion 3 (left side in FIGS. 1 and 2 ) once by the engagement portion 11 a of the guide plate 11 as described above, and is guided to the processing portion 3 positioned on a right side in FIGS. 1 and 2 .
- a drive signal is sent from control means (not shown) to the processing head 4 .
- the processing head 4 performs a processing with respect to the continuous sheet 1 and the driving means (not shown) allows the platen roller 5 to be rotated, thereby transporting the continuous sheet 1 .
- An operation of the processing head 4 and an operation of the platen roller 5 are synchronized with each other, thereby successively performing a processing with respect to the continuous sheet 1 .
- the processing head 4 may be a thermal head or the like. Printing on the continuous sheet 1 or thermal activation by heating the heat-sensitive adhesive layer provided to the continuous sheet 1 is performed.
- the transportation of the continuous sheet 1 is stopped and the movable blade (not shown) of the cutter portion is moved toward the stationary portion 6 , thereby cutting off the continuous sheet 1 which has undergone the processing.
- the transportation of the continuous sheet 1 by the platen roller 5 and the processing by the processing head 4 are performed again, the transportation of the continuous sheet 1 is stopped, and the continuous sheet 1 is cut off.
- the roll body hardly moves and only rotates, so the stable transportation of the continuous sheet 1 is possible.
- the reason for performing the irregular movement such as the lifting up of the roll body 1 a together with the transportation of the continuous sheet 1 is conceived that, as schematically shown in FIG. 3A , the platen roller 5 of the processing portion 3 positioned above the roll body accommodating portion 2 rotates and a force attempting to transport the continuous sheet 1 acts mainly in a direction in which the roll body 1 a is lifted up against the gravity, that is, a component of the force in a vertically upward direction is large.
- the roll body 1 a In the case where the roll body 1 a is lifted up, when, for example, the continuous sheet is cut off, the rotation of the platen roller 5 is stopped to temporarily stop the transportation of the continuous sheet 1 , and a force for lifting up the roll body 1 a is thus eliminated, thereby causing the roll body 1 a to fall down due to the gravity.
- the lifting up and the falling down of the roll body 1 a are repeated, so a position of the roll body 1 a does not become stable, and due to an impact or a reaction in the lifting up and the falling down of the roll body 1 a, the roll body 1 a is oriented obliquely with respect to a longitudinal direction thereof, whereby the roll body 1 a is not held in a stable manner.
- the force generated by the rotation of the platen roller 5 of the processing portion 3 positioned above the roll body accommodating portion 2 acts as a force for pulling the continuous sheet 1 in the substantially horizontal direction from a portion engaged with the engagement portion 11 a of the guide plate 11 but hardly acts in the direction of lifting up the roll body 1 a against the gravity (vertically upward direction). Therefore, the roll body 1 a is not lifted up by the force for transporting the continuous sheet 1 .
- the position of the portion of the continuous sheet 1 engaged with the engagement portion 11 a of the guide plate 11 is biased to the opposite side (left side in FIGS. 1 to 3 ) of the processing portion 3 . Accordingly, the continuous sheet 1 always receives a tensile force in the horizontal direction in the engagement portion thereof, thereby being tensioned. Therefore, there is no play allowing the roll body 1 a to bounce up and down. For those reasons, in this embodiment, it is probable that the roll body 1 a is hardly lifted up together with the transportation of the continuous sheet 1 . The roll body 1 a is not lifted up, so as a matter of course, the roll body 1 a does not fall down due to the gravity when the transportation of the continuous sheet 1 is stopped.
- the roll body 1 a is held in the portion having the substantially V shape formed by the pair of inclination surfaces 2 a, so the roll body 1 a hardly moves in the horizontal direction (left-and-right direction in FIGS. 1 to 3 A- 3 B).
- the path is formed in the processing portion 3 such that the continuous sheet 1 is once moved upwardly by a slight distance, and after that, the continuous sheet 1 is allowed to reach a position between the processing portion 3 and the platen roller 5 to be transported in the horizontal direction.
- a portion for allowing the continuous sheet 1 to be transported upwardly by the slight distance also has a buffering function regarding the transmission of the transportation force.
- a position P 1 of the engagement. portion 11 a of the guide plate 11 when viewed in the horizontal direction (left-and-right direction in FIG. 3B ), a position P 1 of the engagement. portion 11 a of the guide plate 11 must be arranged at least on the opposite side (left side in the figure) of the side (right side in the figure) on which the processing portion 3 is positioned with respect to the position P 3 directly above the central axis of the roll body 1 a.
- the engagement portion 11 a is preferably arranged while being biased to the opposite side (left side in the figure) of the side (right side in the figure) on which the processing portion 3 is positioned with respect to a position P 2 at an outermost end of the roll body 1 a.
- the transport path such that the continuous sheet 1 is once guided to the opposite side (left side in the figure) of the processing portion 3 by the engagement portion 11 a of the guide plate 11 with respect to the path in the case of straightly transporting the continuous sheet from the roll body 1 a to the processing portion 3 (see FIG. 3A ), and after that, the direction of the continuous sheet 1 is changed again to be lead to the processing portion 3 .
- the roll body 1 a is not lifted up or falls down as described above and is held in the stable manner, thereby enabling the favorable transportation.

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 (L1) and (L2) 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).
Description
- 1. Field of the Invention
- The present invention relates to a continuous sheet processing method and a continuous sheet processing apparatus for performing a processing such as printing or thermal activation with respect to a continuous sheet.
- 2. Description of the Related Art
- Hitherto, there is commonly-known a continuous sheet processing apparatus, in which a continuous sheet is successively drawn out from a roll body to perform a processing such as printing or thermal activation with respect to the continuous sheet which is drawn out and a portion thereof subjected to the processing is performed is cut off, thereby obtaining cut form paper.
- As a method of holding the roll body in the continuous sheet processing apparatus as described above, as disclosed in
Patent Document 1, there is available a method in which a central shaft (roll shaft) is inserted into a central hole of a roll body and end portions of the central shaft, which laterally protrude from the roll body, are supported by a frame (first related art example) Further, as disclosed inPatent Document 2, there is available a method in which a fitting portion of each of bobbins (holders) provided to a frame is inserted into a central hole of a roll body from a side thereof, for supporting the roll body (second related art example). Further, as disclosed inPatent Documents - [Patent Document 1] JP 2003-146493 A
- [Patent Document 2] JP 2000-211777 A
- [Patent Document 3] JP 2003-251875 A
- [Patent Document 4] JP 2001-293927 A
- In the first related art example described above, there are required an operation of inserting the central shaft into the central * hole of the roll body and an operation of attaching the central shaft holding the roll body to the frame, thereby being troublesome. Further, in order to prevent a situation where the central shaft detachable with respect to the frame is lost by mistake, thereby making supporting of the roll body thereafter impossible, a user must be cautious. In particular, in a case where the user. misconceives that the central shaft is an accessory of the roll body, after processing of an entire continuous sheet drawn out from the roll body is completed, when the roll body is consumed, the central shaft is discarded. After that, when there is a need for a new roll body to be used, the central shaft is not available, so there may arise a problem in that holding of the roll body cannot be performed.
- In the second related art example, the bobbin is provided to the frame so as not to be removable therefrom. Accordingly, unlike in the first related art example, there is no risk of losing the bobbin by mistake. Further, only by one operation of inserting the bobbin into the central hole of the roll body, the holding of the roll body is completed. Accordingly, the number of operations decreases compared to the first related art example requiring the two operations. However, the operation of inserting the bobbin into the central hole of the roll body in a confined space of the roll body accommodating portion is extremely complicated. Specifically, positioning of the fitting portion of the bobbin with respect to the central hole of the roll body by fumbling of the user, and moving the fitting portion of the bobbin with respect to the frame to insert the fitting portion into the central hole are extremely complicated. In particular, in a case where a clearance between the fitting portion of the bobbin and the central hole of the roll body is smaller, positioning and insertion operations become more complicated. Further, at a time of positioning or attaching, there is a risk of damaging a side portion of the roll body by a tip of the fitting portion of the bobbin, thereby leaving a flaw or deformation in an edge portion of the continuous sheet.
- In the first and second related art examples, when the roll body is not set in a correct position by the central shaft or the bobbin, it is impossible to draw out the continuous sheet from the roll body to supply the continuous sheet to a processing portion.
- In contrast, in the third and fourth related art examples, there is no need of an attachment operation of inserting the central shaft or the fitting portion of the bobbin into the central hole of the roll body, or the like, and there is only need of inserting the roll body into the roll body accommodating portion, so operability is remarkably favorable.
- An example of the above-mentioned structure is shown in
FIG. 19 . In this structure, aprocessing portion 3 is provided above and on a lateral side of a roll body accommodating portion 2 (position shifted in horizontal direction from position directly above central axis ofroll body 1 a accommodated in roll body accommodating portion 2). Aplaten roller 5 of theprocessing portion 3 is rotated, thereby allowing thecontinuous sheet 1 of theroll body 1 a to be successively drawn out to be supplied to theprocessing portion 3. - The
roll body 1 a is hardly restricted in a space of the rollbody accommodating portion 2 and freely movable therein. Therefore, when thecontinuous sheet 1 drawn out from theroll body 1 a is transported while being pulled by aplaten roller 5 provided to theprocessing portion 3, there is such a risk that theroll body 1 a randomly moves in theroll accommodating body 2 by the pulling force. In particular, in the structure as shown inFIG. 19 , theprocessing portion 3 is positioned above the rollbody accommodating portion 2. Accordingly, at a time of transporting thecontinuous sheet 1, there is a fear of theroll body 1 a being lifted up. Theroll body 1 a does not stably become standstill in a state where theroll body 1 a is lifted up, and performs irregular operations in the rollbody accommodating portion 2. In particular, in a case where thecontinuous sheet 1 is intermittently transported, when transportation of thecontinuous sheet 1 is performed (whencontinuous sheet 1 is pulled up), theroll body 1 a is lifted up, and when transportation of thecontinuous sheet 1 is not performed (whencontinuous sheet 1 is not pulled), theroll body 1 a falls down on a bottom surface of the rollbody accommodating portion 2 due to the gravity. In a case where the lifting up and the falling down of theroll body 1 a are repeated as described above, large irregular movements of theroll body 1 a are caused. As a result, thecontinuous sheet 1 cannot be correctly supplied to theprocessing portion 3. Therefore, there occurs operation failures, in which, for example, thecontinuous sheet 1 is transported while being oriented obliquely, a transport speed becomes nonuniform, and finally, the transportation is impossible. Further, there is a risk of causing abnormalities in processing by aprocessing head 4 of theprocessing portion 3, such as printing failure, and variation in or absence of thermal activation. - Further, in the roll
body accommodating portion 2, there may be provided asensor 18 for detecting a size of theroll body 1 a, that is, a remaining amount of the sheet by performing detection on a part of theroll body 1 a. In this case, when theroll body 1 a performs the irregular operations such as the lifting up of theroll body 1 a as described above in the rollbody accommodating portion 2 and theroll body 1 a temporarily gets out of a detection region of thesensor 18, there is a risk of making misjudgment that the remaining amount of the sheet is small regardless of the size of theroll body 1 a. - It is therefore an object of the present invention to provide a continuous sheet processing apparatus and a continuous sheet processing method capable of, even with a structure in which setting of the roll body in the roll body accommodating portion is extremely easy, stably transporting the continuous sheet drawn out from the roll body without causing the irregular movements such as the lifting up of the roll body.
- A continuous sheet processing apparatus according-to the present invention includes: 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, in which 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.
- With this structure, even in a case where, when accommodating the roll body in the roll body accommodating portion, there is no need of special positioning and attachment operations and setting can easily be achieved by only inserting the roll body into the roll body accommodating portion, when the continuous sheet drawn out from the roll body is transported by being pulled by the processing portion positioned above the roll body accommodating portion, the roll body does not involve a movement such as lifting up thereof.
- In particular, it is preferable that the engagement portion be 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. Note that the drawing out portion herein means a portion where the continuous sheet comes off from the roll body. In the present invention, the guide member exists. Accordingly, there is a possibility of the drawing out portion of the roll body being different in position from that in a case where there is formed a transport path for linearly supplying the continuous sheet from the roll body to the processing portion. It is preferable that the engagement portion be arranged in such a position that the engagement portion once guides the continuous sheet to the opposite side of the processing portion with respect to both a straight line connecting the processing portion and the drawing out portion of the roll body in a case where there exists the guide member, and a straight line connecting the processing portion and the drawing out portion of the roll body in a case where there exists no guide member.
- It is preferable that the engagement portion be 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.
- In this case, when the engagement portion is positioned while being biased to the opposite side of the processing portion with respect to an outermost end of the roll body of a maximum size which can be accommodated in the roll body accommodating portion, it is possible to always obtain an operational effect of the present invention with reliability. However, a problem such as lifting up of the roll body is caused mainly in a state where the roll body is relatively small, so there may be employed a structure in which, with reference to the roll body having a size with which the problem is likely to occur, the engagement portion is positioned while being biased to the opposite side of the processing portion with respect to the outermost end of the roll body.
- The continuous sheet processing apparatus may include 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.
- The processing portion includes: 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 arranged to oppose the processing head, for transporting the continuous sheet. The processing portion may include a printing portion for performing printing on the continuous sheet drawn out from the roll body. Alternatively, the processing portion may include a thermal activation portion for heating and thermally activating the continuous sheet drawn out from the roll body.
- Further, the present invention has another characteristic point in that, in a continuous sheet processing method of performing a processing with respect to a continuous sheet by a processing portion by drawing out the continuous sheet from a roll body accommodated in a roll body accommodating portion and 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, 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.
- The continuous sheet which has been subjected to the processing by the processing portion may be cut off by a cutter portion positioned on a downstream side of the processing portion.
- Printing may be performed by the processing portion on the continuous sheet drawn out from the roll body. Further, the continuous sheet drawn out from the roll body may be heated and thermally activated by the processing portion.
- According to the present invention, even in the structure in which the roll body can easily be set only by being put into the roll body accommodating portion, there is not involved the movement such as the lifting up of the roll body at the time of transporting the continuous sheet drawn out from the roll body, thereby enabling favorable transportation thereof.

- (Structure of Continuous Sheet Processing Apparatus)
-
FIGS. 1 and 2 each show an inner structure of a continuous sheet processing apparatus of the present invention.FIG. 1 shows a state where aroll body 1 a in which acontinuous sheet 1 is wound is accommodated therein.FIG. 2 shows a state where theroll body 1 a is not accommodated therein. The continuous sheet processing apparatus includes a rollbody accommodating portion 2 for accommodating theroll body 1 a and aprocessing portion 3 provided in a position above and on a lateral side of the roll body accommodating portion 2 (right side inFIGS. 1 and 2 , that is, position shifted in horizontal direction from position P3 (seeFIG. 3B ) directly above central axis ofroll body 1 a accommodated in roll body accommodating portion 2). - The roll
body accommodating portion 2 has a pair of inclination surfaces 2 a forming a substantially V shape section, for supporting an outermost peripheral surface of theroll body 1 a. Both the pair of inclination surfaces 2 a come into line contact (point contact when viewed in sectional view as shown inFIG. 1 ) with the outermost peripheral surface of the roll body la, thereby supporting theroll body 1 a. With this structure, a center of theroll body 1 a accommodated in the rollbody accommodating portion 2 and a center of the rollbody accommodating portion 2 are positioned on the same straight line. That is, positions of the center of the rollbody accommodating portion 2 and the center of theroll body 1 a substantially coincide with each other at least in a width direction (left-and-right direction inFIGS. 1 and 2 ) of the apparatus. In the rollbody accommodating portion 2, there is provided asensor 18 for detecting a remaining amount of theroll body 1 a. - The
processing portion 3 includes aprocessing head 4 and aplaten roller 5 positioned so as to be opposed to theprocessing head 4. Theprocessing head 4 and theplaten roller 5 sandwich therebetween thecontinuous sheet 1 processed in the present invention. Theplaten roller 5 supports thecontinuous sheet 1 while pressing thecontinuous sheet 1 to theprocessing head 4 and is driven by driving means (not shown) to be rotated to successively transport thecontinuous sheet 1. Theprocessing head 4 performs the processing with respect to thecontinuous sheet 1 supported by theplaten roller 5. Examples thereof include a recording head for performing recording on a continuous sheet having a recordable surface, and a thermal activation head for generating adhesiveness by heating a continuous sheet having a heat-sensitive adhesion surface. On a downstream side of theprocessing head 4 and theplaten roller 5, a cutter portion is provided. Further, on a downstream side of the cutter portion, anoutlet 7 to an outside is provided. The cutter portion of this embodiment includes a movable blade and astationary blade 6 opposed to the movable blade (not shown). The movable blade moves toward thestationary blade 6, thereby making it possible to cut thecontinuous sheet 1. In each ofFIGS. 1 and 2 , the movable blade is positioned in a retracted position, so the movable blade is not shown. - In the continuous sheet processing apparatus, there is provided a
cover 8. Thecover 8 pivots about ashaft 9, thereby being capable of opening and closing with respect to aframe 17. Theplaten roller 5 and thestationary blade 6 of the cutter portion are mounted to thecover 8 throughsupport members 10 and move integrally with thecover 8. - To the
cover 8, a guide plate (guide member) 11 is mounted througharms 12. Each of thearms 12 is mounted to each offirst projection portions 8 a, which are provided to thecover 8, so as to be pivotal about ashaft 13. Further, between each of thearms 12 and each ofsecond projection portions 8 b provided to thecover 8, alink arm 14 is mounted. Each of thelink arms 14 is pivotal about a shaft 15 (seeFIG. 4B ) with respect to each of thearms 12, and is also pivotal about ashaft 16 with respect to thecover 8. By thearms 12 and thelink arms 14, theguide plate 11 can be moved within a certain movement range independently of thecover 8. Further, although not shown, between each of thearms 12 and a part of thecover 8, a spring (not shown) is provided. Note that, as shown in a perspective view ofFIG. 4A ) or the like, thearm 12, thelink arm 14, and theprojection portions cover 8. Theguide plate 11 is mounted so as to extend between thefirst link arms 12 positioned on the both side portions. - Each of the
link arms 14 is provided with a protrudingportion 14 a. An inner surface of theframe 17 is provided withcams 17 a. Further, each of thearms 12 is provided with a protrudingportion 12 a. The inner surface of theframe 17 is also provided withguide grooves 17 b. Therefore, in a later-described operation of closing thecover 8, when the protrudingportions 14 a come into contact with thecams 17 a, thelink arms 14 are pushed, and against a spring force of the springs (not shown), thelink arms 14, thearms 12, and theguide plate 11 are moved as an operation independent of a movement of thecover 8 or as a combined operation of an opening and closing operation of thecover 8 and a relative movement with respect to thecover 8. Further, the movement is regularly performed by allowing the protrudingportions 12 a of thearms 12 to slide into theguide grooves 17 b. - As shown in
FIGS. 1 and 2 , when thecover 8 is in a closed state, a position of an end portion of theguide plate 11 is biased to an opposite side of the processing portion 3 (left side inFIGS. 1 and 2 ). At least the end portion operates as anengagement portion 11 a engaging with thecontinuous sheet 1. - Here, when a consideration is made of a transport path for the continuous sheet, if the
guide plate 11 does not exist, the transport path for the continuous sheet is formed along a straight line L1 connecting between a drawing out portion of theroll body 1 a and theprocessing portion 3. In contrast to this, in the structure of this embodiment, as shown inFIG. 1 , theengagement portion 11 a of theguide plate 11 forms the transport path which guides thecontinuous sheet 1 to the opposite side of the processing portion 3 (left side inFIGS. 1 and 2 ) once with respect to the straight line L1 and guides thecontinuous sheet 1 to theprocessing portion 3 thereafter. In a strict sense, in a case where theguide plate 11 exists, a position of the drawing out portion of theroll body 1 a slightly moves, and a straight line L2 connecting the drawing out portion of theroll body 1 a in this case and theprocessing portion 3 is slightly different from the straight line L1. Theengagement portion 11 a is arranged so as to guide thecontinuous sheet 1 to the opposite side of the processing portion 3 (left side inFIGS. 1 and 2 ) once with respect to both the straight line L1 and the straight line L2. - In this embodiment, a bottom surface portion, on which the inclination surfaces 2 a for supporting the
roll body 1 a are provided, is also connected to thecover 8. On an outer portion of theframe 17, although not described in detail, apanel 19 provided with a display portion, an input portion, and the like is arranged. - (Outline of Processing Method for Continuous Sheet)
- A description will be made of an outline about a processing operation by the continuous sheet processing apparatus. First, the
roll body 1 a is set in the continuous sheet processing apparatus. The setting operation may be performed by only inserting theroll body 1 a into a space of the rollbody accommodating portion 2. At this time, in a state where an end of thecontinuous sheet 1 is pulled out from theroll body 1 a and is sandwiched between theprocessing head 4 of theprocessing portion 3 and theplaten roller 5, thecover 8 is closed. At this time, thecontinuous sheet 1 pulled out from theroll body 1 a is guided to the opposite side of the processing portion 3 (left side inFIGS. 1 and 2 ) once by theengagement portion 11 a of theguide plate 11 as described above, and is guided to theprocessing portion 3 positioned on a right side inFIGS. 1 and 2 . - In this state, a drive signal is sent from control means (not shown) to the
processing head 4. As a result, theprocessing head 4 performs a processing with respect to thecontinuous sheet 1 and the driving means (not shown) allows theplaten roller 5 to be rotated, thereby transporting thecontinuous sheet 1. An operation of theprocessing head 4 and an operation of theplaten roller 5 are synchronized with each other, thereby successively performing a processing with respect to thecontinuous sheet 1. Note that theprocessing head 4 may be a thermal head or the like. Printing on thecontinuous sheet 1 or thermal activation by heating the heat-sensitive adhesive layer provided to thecontinuous sheet 1 is performed. When the processing of thecontinuous sheet 1 of a predetermined length is completed, the transportation of thecontinuous sheet 1 is stopped and the movable blade (not shown) of the cutter portion is moved toward thestationary portion 6, thereby cutting off thecontinuous sheet 1 which has undergone the processing. In a case of successively performing the processing of thecontinuous sheet 1, the transportation of thecontinuous sheet 1 by theplaten roller 5 and the processing by theprocessing head 4 are performed again, the transportation of thecontinuous sheet 1 is stopped, and thecontinuous sheet 1 is cut off. - As described above, also in a case of intermittently transporting the
continuous sheet 1 through the rotation of theplaten roller 5, according to this embodiment, the roll body hardly moves and only rotates, so the stable transportation of thecontinuous sheet 1 is possible. - (Consideration of Transportation State of Continuous Sheet)
- As described above, consideration will be made below of a reason why the stable transportation of the
continuous sheet 1 is enabled by this embodiment. - In the related art structure in which the
guide plate 11 does not exist, the reason for performing the irregular movement such as the lifting up of theroll body 1 a together with the transportation of thecontinuous sheet 1 is conceived that, as schematically shown inFIG. 3A , theplaten roller 5 of theprocessing portion 3 positioned above the rollbody accommodating portion 2 rotates and a force attempting to transport thecontinuous sheet 1 acts mainly in a direction in which theroll body 1 a is lifted up against the gravity, that is, a component of the force in a vertically upward direction is large. In the case where theroll body 1 a is lifted up, when, for example, the continuous sheet is cut off, the rotation of theplaten roller 5 is stopped to temporarily stop the transportation of thecontinuous sheet 1, and a force for lifting up theroll body 1 a is thus eliminated, thereby causing theroll body 1 a to fall down due to the gravity. The lifting up and the falling down of theroll body 1 a are repeated, so a position of theroll body 1 a does not become stable, and due to an impact or a reaction in the lifting up and the falling down of theroll body 1 a, theroll body 1 a is oriented obliquely with respect to a longitudinal direction thereof, whereby theroll body 1 a is not held in a stable manner. As a result, a favorable transportation state of the continuous sheet cannot be continued, thereby causing processing failures (such as printing failure and variation in thermal activation). Further, when theroll body 1 a is temporarily lifted up, the roll body la gets out of the detection range of thesensor 18, and there is a risk of making misjudgment that the remaining amount of thecontinuous sheet 1 is small even though the remaining amount of thecontinuous sheet 1 is sufficient. - In contrast to this, in this embodiment, as schematically shown in
FIG. 3B ), the force generated by the rotation of theplaten roller 5 of theprocessing portion 3 positioned above the rollbody accommodating portion 2, which attempts to transport thecontinuous sheet 1, acts as a force for pulling thecontinuous sheet 1 in the substantially horizontal direction from a portion engaged with theengagement portion 11 a of theguide plate 11 but hardly acts in the direction of lifting up theroll body 1 a against the gravity (vertically upward direction). Therefore, theroll body 1 a is not lifted up by the force for transporting thecontinuous sheet 1. Note that it is probable that, while the transport path between theengagement portion 11 a and the drawing out-portion of theroll body 1 a forms an obtuse angle close to the vertically upward direction, the position where thecontinuous sheet 1 is engaged with theengagement portion 11 a of theguide plate 11 functions as a buffer for the transmission force, which is generated by the rotation of theplaten roller 5 to theroll body 1 a, in a midway of the transmission of the transportation force. Therefore, a force which is abrupt and strong enough to lift up theroll body 1 a against the gravity is not transmitted to theroll body 1 a. - Further, in this embodiment, the position of the portion of the
continuous sheet 1 engaged with theengagement portion 11 a of theguide plate 11 is biased to the opposite side (left side inFIGS. 1 to 3 ) of theprocessing portion 3. Accordingly, thecontinuous sheet 1 always receives a tensile force in the horizontal direction in the engagement portion thereof, thereby being tensioned. Therefore, there is no play allowing theroll body 1 a to bounce up and down. For those reasons, in this embodiment, it is probable that theroll body 1 a is hardly lifted up together with the transportation of thecontinuous sheet 1. Theroll body 1 a is not lifted up, so as a matter of course, theroll body 1 a does not fall down due to the gravity when the transportation of thecontinuous sheet 1 is stopped. It is possible to prevent thesensor 18 from making the misjudgment. Note that, in this embodiment, theroll body 1 a is held in the portion having the substantially V shape formed by the pair of inclination surfaces 2 a, so theroll body 1 a hardly moves in the horizontal direction (left-and-right direction in FIGS. 1 to 3A-3B). - Further, in this embodiment, the path is formed in the
processing portion 3 such that thecontinuous sheet 1 is once moved upwardly by a slight distance, and after that, thecontinuous sheet 1 is allowed to reach a position between the processingportion 3 and theplaten roller 5 to be transported in the horizontal direction. A portion for allowing thecontinuous sheet 1 to be transported upwardly by the slight distance also has a buffering function regarding the transmission of the transportation force. As described above, it is probable that the more direction conversion portions are provided in the transmission path for the force (path corresponding to transport path of continuous sheet 1), which extends from the portion generating the transportation force (platen roller 5) to the portion which may be moved (rollbody 1 a), the larger effects of absorbing and buffering the impact become, thereby suppressing the abrupt and irregular movement of theroll body 1 a. For that implication, in this embodiment, there are provided more direction conversion portions than in a related art invention. Accordingly, it is possible to prevent undesirable movements such as the lifting up of the roll body. - In order to obtain the effect of the present invention as described above, when viewed in the horizontal direction (left-and-right direction in
FIG. 3B ), a position P1 of the engagement.portion 11 a of theguide plate 11 must be arranged at least on the opposite side (left side in the figure) of the side (right side in the figure) on which theprocessing portion 3 is positioned with respect to the position P3 directly above the central axis of theroll body 1 a. Theengagement portion 11 a is preferably arranged while being biased to the opposite side (left side in the figure) of the side (right side in the figure) on which theprocessing portion 3 is positioned with respect to a position P2 at an outermost end of theroll body 1 a. By keeping the positional relationships as described above, there is structured the transport path such that thecontinuous sheet 1 is once guided to the opposite side (left side in the figure) of theprocessing portion 3 by theengagement portion 11 a of theguide plate 11 with respect to the path in the case of straightly transporting the continuous sheet from theroll body 1 a to the processing portion 3 (seeFIG. 3A ), and after that, the direction of thecontinuous sheet 1 is changed again to be lead to theprocessing portion 3. As a result, theroll body 1 a is not lifted up or falls down as described above and is held in the stable manner, thereby enabling the favorable transportation. - (Opening and Closing Operation of Cover)
- Next, the opening and closing operation of the
cover 8 according to this embodiment will be described with reference toFIGS. 4A-4C to 11A-11C. Here, the description will be made of an operation of closing thecover 8 in a state where thecover 8 is in the open state. Note that, in each ofFIGS. 4A-4C and 6A-6C to 11A-11C,FIGS. 4A , 6A, 7A, 8A, 9A, 10A and 11A are a perspective view in which illustration of theroll body 1 a is omitted,FIGS. 4B , 6B, 7B, 8B, 9B, 10B and 11B are a sectional view in which illustration of theroll body 1 a is omitted, andFIGS. 4C , 6C, 7C, 8C, 9C, 10C and 11C are a sectional view including theroll body 1 a. -
FIGS. 4A-4C each show a state where thecover 8 is completely opened. In this state, by the spring force of the springs (not shown), thearms 12 are in the open state together with thecover 8. In this state, theroll body 1 a is inserted into thecover 8. In this state, theroll body 1 a is held in a relatively stable manner by one (right one in the figures) of the inclination surfaces 2 a on the bottom surface portion connected to thecover 8 and aninclination surface 8c provided to the cover 8 (see,FIG. 4C ). - Next, the
cover 8 starts to be closed. At this time, the protrudingportions 14 a of thelink arms 14 abut on thecams 17 a of theframe 17. A state at a start of the abutment is shown inFIG. 5A ). A portion A ofFIG. 5A is shown inFIG. 5B by being enlarged. Further, in order to clarify positions and shapes of the protrudingportion 14 a and thecam 17 a,FIG. 5C shows an exploded perspective view. When the protrudingportions 14 a of thelink arms 14 abut on thecams 17 a to be pushed, as shown inFIGS. 6A-6C , thelink arms 14 pivot about the shaft 16 (see,FIG. 4B ) with respect to thecover 8. Along with the pivoting of thelink arms 14, thearms 12 connected to thelink arms 14 through theshaft 15 pivot about theshaft 13 with respect to thecover 8. The pivoting is a movement in which thearms 12 and theguide plate 11 close toward theframe 17 before thecover 8. As described above, in this embodiment, a link mechanism includes thearms 12 and thelink arms 14. - In the state where the protruding
portion 14 a of thelink arms 14 abut on thecams 17 a, when thecover 8 itself is closed toward theframe 17, as shown inFIGS. 7A-7C to 10A-10C in the stated order, thearms 12 and theguide plate 11 enter theframe 17 toward a deeper side (left side in the figures) thereof before thecover 8. In this case, as shown inFIG. 8C , theguide plate 11 enter a space under thecontinuous sheet 1 drawn out from theroll body 1 a, that is, between theroll body 1 a and thecontinuous sheet 1 drawn out from the roll body. Further, as shown inFIGS. 8A-8C , the protrudingportions 12 a of the arms enter inside theguide grooves 17 b of the frame-17. Each of theguide grooves 17 b is wide on an open side (right side in the figures), thereby allowing the protrudingportion 12 a of thearm 12 to easily enter theguide groove 17 b. Further, each of theguide grooves 17 b becomes narrower toward a deeper side (left side in the figures), so a movement path of each of the protrudingportions 12 a is gradually restricted, thereby allowing each of thearms 12 to be correctly guided to a predetermined portion at last. As shown inFIG. 9A-9C , after theguide plate 11 reaches a position above the central axis of theroll body 1 a, theguide plate 11 is further moved, and as shown inFIGS. 10A-10C , reaches a side (opposite side of the processing portion 3) deeper than the central axis of theroll body 1 a. At last, as shown inFIGS. 11A-11C , thecover 8 is completely closed. - Note that, in an operation in which the
cover 8 is opened in a state where thecover 8 is closed, an operation completely opposite to that described above is performed. That is, the operation is performed in the state shown inFIGS. 11A-11C , the state shown inFIGS. 10A-10C , the state shown inFIGS. 9A-9C , the state shown inFIGS. 8A-8C , the state shown inFIGS. 7A-7C , the state shown inFIGS. 6A-6C , and the state shown inFIGS. 4A-4C in the stated order. In this case, when thecover 8 starts to open, the protrudingportions 14 a of thelink arm 14 abut on thecams 17 a, thereby restricting the movement of the protrudingportions 14 a. Accordingly, theguide plate 11 and thearms 12 open after the movement of thecover 8. - In this embodiment, as shown in FIGS. 1 to 3A-3B and 11A-11C, when the
cover 8 is in the closed state, the position P1 of the end portion of theengagement portion 11 a of theguide plate 11 is on the opposite side of the processing portion 3 (left side in the figures) with respect to the position P3 (the same as center of roll body accommodating portion 2) directly above the central axis of theroll body 1 a. If theguide plate 11 is fixed to the above-mentioned position, in a case where thecover 8 is opened to insert theroll body 1 a into the rollbody accommodating portion 2, it is highly difficult to set the end portion of thecontinuous sheet 1 drawn out from theroll body 1 a such that the end portion passes above theguide plate 11 to be guided to theprocessing portion 3. That is, an operation, in which the end portion of thecontinuous sheet 1 drawn out from theroll body 1 a is allowed to pass through a confined space between theroll body 1 a and an upper wall of theframe 17 within an extremely small operation space as being understood with reference toFIG. 11C , requires highly intricate work, thereby being extremely difficult. - If the structure allows the
cover 8 to be opened to nearly 180 degrees, before theroll body 1 a is inserted into the rollbody accommodating portion 2, in a state where a relatively large operation space is ensured, it is possible to perform the operation of allowing the end portion of thecontinuous sheet 1 to pass through a space above theguide plate 11. Therefore, it is probable that operability increases. However, with the structure according to this embodiment, in which theprocessing portion 3 is positioned above the rollbody accommodating portion 2 and thecover 8 pivots about theshaft 9 positioned on a lower portion of theframe 17 to be opened and closed, the cover cannot be opened to 90 degrees or more in a state where the apparatus of the present invention is kept placed on a plane. Accordingly, there is a need of temporarily tilting the apparatus to open thecover 8. Thus, the apparatus becomes a product which is extremely difficult to use practically, thereby being unpreferable. - When considerations are made for those cases, the applicant of the present invention conceives that it is preferable that, in the state where the
cover 8 is opened, theguide plate 11 be not in the position on the opposite side (left side in the figure) of theprocessing portion 3 with respect to the P3 directly above the central axis of theroll body 1 a as shown in FIGS. 1 to 3A-3B and 11, and theguide plate 11 be provided outside theframe 17 in the same manner as with thecover 8. In the present invention, with the structure with which theguide plate 11 is made movable as the operation independent of thecover 8 or as the combined operation of the opening and closing operation of thecover 8 and the relative movement with respect to thecover 8, there is first realized the structure in which, in the state where theroll body 1 a is inserted into the rollbody accommodating portion 2, when thecover 8 is closed, while keeping the end portion of thecontinuous sheet 1 drawn out from theroll body 1 a positioned above theguide plate 11, theguide plate 11 can be moved to the position P1 on the opposite side (left side in the figures) of theprocessing portion 3. In particular, in the above embodiment, with the link mechanism including thearms 12 and thelink arms 14, theguide plate 11 can move as the combined operation of the opening and closing operation of thecover 8 and relative pivoting with respect to thecover 8. As a result, by only performing an operation in which, when thecover 8 is opened, theroll body 1 a is inserted into the rollbody accommodating portion 2 in the state where the end portion of thecontinuous sheet 1 is drawn out, and thecover 8 is closed, it is possible to arrange thecontinuous sheet 1 on theguide plate 11 and to move the guide plate to the predetermined position P1. There is no need for the user to allow thecontinuous sheet 1 to pass through the confined space between theguide plate 11 and the upper wall of theframe 17. Further, there is also no need to directly move theguide plate 11 itself. It is only necessary to perform the operation of inserting theroll body 1 a and closing thecover 8, so the operability is extremely high. As is apparent fromFIGS. 4A-4C , those operations can sufficiently be performed at an opening angle of thecover 8 of less than 90 degrees. Accordingly, the operations can be performed while keeping the apparatus placed on a plane, thereby making it possible to realize a practically easy-to-use structure thereof. - Note that, as an additional effect of this embodiment, it is exemplified that, as shown in
FIGS. 4A-4C and 12A-12B, in the state where thecover 8 is opened, thestationary blade 6 of the cutter portion is covered with theguide plate 11, thereby not being exposed to the outside, so there is no risk that the user touches thestationary blade 6 by mistake. - Next, with reference to FIGS. 13 to 18A-18C, another embodiment of the present invention will be described.
FIGS. 13 and 14 each show an internal structure of a continuous sheet processing apparatus according to a second embodiment of the present invention.FIG. 13 shows a state where theroll body 1 a, in which thecontinuous sheet 1 is wound, is accommodated.FIG. 14 shows a state where theroll body 1 a is not accommodated. - The continuous sheet processing apparatus according to this embodiment does not include the
link arms 14, theshafts link arms 14, thecams 17 a, and theguide grooves 17 b. Further, the springs (not shown) biases thearms 12 toward theframe 17 side. That is, a direction of a bias force applied to thearms 12 by the springs is substantially opposite to that of the first embodiment described above. Other constructions are the same as those of the first embodiment shown inFIGS. 1 and 2 , so descriptions thereof will be omitted. - In this embodiment as well, as shown in
FIG. 13 , the position P1 of theengagement portion 11 a of theguide plate 11 is on the opposite side (left side in the figure) of theprocessing portion 3 with respect to the position P3 directly above the central axis of the roll body la. By theguide plate 11, there is structured the transport path such that thecontinuous sheet 1 is once guided to the opposite side (left side inFIG. 13 ) of theprocessing portion 3 with respect to the straight lines L1 and L2 each connecting the drawing out portion of theroll body 1 a and theprocessing portion 3, and is guided to theprocessing portion 3 thereafter. - In this embodiment, the
guide plate 11 and thearms 12 do not move together with the opening and closing operation of thecover 8 and are moved manually. Here, a description will be made of an operation in which thecover 8 is opened to set the roll body la in the state where thecover 8 is closed as shown inFIGS. 13 to 15 . - First, by opening the
cover 8 in the state shown inFIG. 15 , as shown inFIG. 16 , theguide plate 11 and thearms 12 are biased by the springs (not shown) to remain in the deeper side (left side in the figures) of the frame. In this state, theguide plate 11 acts as an obstacle, so the insertion and ejection of theroll body 1 a cannot be performed. Accordingly, as shown inFIG. 17A , the user manually pulls out theguide plate 11 and thearms 12 to the outside of theframe 17 against the spring force. Note thatFIG. 17B shows, at an angle different from that ofFIG. 17A , a state where theguide plate 11 and thearms 12 are manually pulled out in the above-mentioned manner so as to approach thecover 8. - In this state, after the
roll body 1 a is inserted into the rollbody accommodating portion 2, when a hand is moved off from theguide plate 11 and thearms 12, by the bias force of the springs (not shown), theguide plate 11 and thearms 12 are moved to the deeper side (left side of the figures) of the frame. Note that a relative moving angle of each of thearms 12 with respect to thecover 8 is restricted by astopper 20. Accordingly, as shown inFIGS. 18A-18B , theguide plate 11 stops before entering inside theframe 17. Note thatFIG. 18A is a perspective view,FIG. 18B is a sectional view in which theroll body 1 a is omitted, andFIG. 18C shows a state where theguide plate 11 has moved to theframe 17 side by being biased by the springs (not shown) at an angle different from that ofFIG. 18A . - At last, when the
cover 8 is closed, theguide plate 11 and thearms 12 are moved integrally with each other to enter inside theframe 17 to reach the deeper side therein, thereby realizing the state as shown in each ofFIGS. 13 and 14 . Note that the restriction of the relative moving angle of each of thearms 12 with respect to thecover 8 by thestopper 20 is set such that theengagement portion 11 a of theguide plate 11 is stopped at the desired position P1 in the state where thecover 8 is completely closed as shown inFIGS. 13 and 14 . - In this embodiment as well, the same operational effect as that of the first embodiment described above is obtained. Note that the
guide plate 11 and thearms 12 have to be manually moved, so the operation becomes a little complicated, but at the same time, the need of thelink arms 14 and thecams 17 a is eliminated. As a result, it is possible to simplify the structure. - In the two embodiments described above, the
guide plate 14 is attached to thecover 8 through thearms 12. However, there may be employed a structure in which theguide plate 14 is pivotally attached to theframe 17 through thearms 12 or another member. In this case, it is possible to more easily realize the structure in which theguide plate 11 and thearms 12 are moved manually in the same manner as that of the second embodiment of the present invention than the structure in which theguide plate 11 and thearms 12 automatically move together with the opening and closing of thecover 8 in the same manner as that of the first embodiment of the present invention. In both the cases, when theguide plate 14 is movable between the predetermined position P1 and the outside of theframe 17 as the operation independent of the opening and closing of thecover 8 or as the combined operation of the opening and closing operation of thecover 8 and the relative movement with respect to thecover 8, the same effect as that described above can be achieved.
