As shown in fig. 7, transfer platen mobile mechanism 6 have solenoid 61, connecting plate 62, connecting rod 63, briquetting 64 and By pressing spring 65.The end portion of connecting rod 63 is mounted on connecting plate 62, and in the state that head 631 penetrates through briquetting 64 It is mounted on briquetting 64, is linked connecting plate 62 and briquetting 64 using connecting rod 63.Briquetting 64 is attached at side plate 42, by pressing Pressing spring 65 presses towards a surface side R1.

Fig. 8 is the figure for illustrating the transformation of the state between the transfer state of transfer platen and backoff state.In fig. 8, The transfer platen 52 for being wrapped around flat belt 53, transfer platen mobile mechanism 6, bonding agent casket 3 and upstream viewed from above are shown The pattern of side conveying roller 51.In addition, showing the backoff state of transfer platen 52 in Fig. 8 (a), in Fig. 8 (b), shows and turn Print the transfer state of roller 52.

As shown in Fig. 8 (a) and Fig. 8 (b), in the plunger 611 of solenoid 61, it is equipped with prominent downward (paper in figure is inboard) Locking pin 611a out.Connecting plate 62 is the plate for overlooking substantially inverted L shape, the end sections on right side by 621 turn of pivot pin from By earth's axis branch.In addition, forming slit 62a in the front side of the left side part of connecting plate 62, guiding long hole is formed in rear side 62b.It is inserted into the locking pin 611a of solenoid 61 in slit 62a, is inserted into guide pins 622 in guiding long hole 62b.In briquetting 64 form rectangular opening 64a, and the head 631 of the connecting rod 63 (referring to Fig. 7) that connecting plate 62 and briquetting 64 are linked is from rectangle Hole 64a is prominent.

When the backoff state of the transfer platen 52 shown in Fig. 8 (a) drives solenoid 61, plunger 611 is as thin in Fig. 8 (b) When prominent like that shown in straight arrows, the front part of the locking pin 611a pressing connecting plate 62 by being inserted into slit 62a, connection Plate 62 is that rotation center is directed to the guiding of pin 622 and counterclockwise slightly with pivot pin 621 as shown in circular arc shaped arrow Turn.When 62 counterclockwise turn of connecting plate, the briquetting 64 linked by connecting plate 62 and connecting rod 63 is as thick straight line Shown in arrow like that, mobile towards a surface side (rear side).Side plate 42 is centered on upstream side axle 511 towards a surface side R1 as a result, Turn (referring to Fig. 7), transfer platen 52 is changed into transfer state shown in Fig. 8 (b).

On the other hand, as shown in straight arrows thin in Fig. 8 (a), when the plunger 611 of solenoid 61 retreats, connection The turn toward the clockwise direction as shown in circular arc shaped arrow of plate 62, briquetting 64 fights exerting pressure by pressing spring 65, as thick It is mobile away from the direction of transfer section W (front side of figure) like that shown in straight arrows.Side plate 42 is as a result, with upstream side axle 511 Centered on, towards the direction turn (referring to Fig. 7) contrary with what it is towards a surface side, transfer platen 52 leaves transfer section W, turns Become backoff state shown in Fig. 8 (a).

By changing the state of transfer platen 52 between transfer state and backoff state, state can be made to exist Change between the state transferred and non-transfer state.That is, by adjusting the state of transfer platen 52 is changed Moment can make bonding agent be transferred to the required position of the conveyance direction of the paper P moved.For example, bonding agent can be made The overall length transfer of the conveyance direction of the paper P cut off throughout cut-off knife mechanism 23 as shown in Figure 4, and can also bonding agent be made only to turn Print to conveyance direction upstream part or conveyance direction downstream side part.Further, it is possible to make bonding agent completely non-transferly Pass through transfer section W.

Fig. 9 is from left diagonally forward from the perspective view of the rear casing of printer removal shown in Fig. 2.Figure 10 is to choose The major part of Unit the 2nd in bonding agent transfer unit shown in Fig. 4 and the figure shown.In addition, in Fig. 9 and Figure 10, benefit Transport path R is indicated with thick dashed line arrow.

As shown in figure 9, in addition to the 2nd unit 10b, being additionally provided with platen roller 221 in rear casing 12.2nd unit 10b tool There is setting that the front side wall portion 46 of front part is set, in the front side wall portion 46, forms transfer section W with removing guiding element 7 preceding The notch 46a that side is exposed.In addition, in front side wall portion 46, in the lower position of notch 46a, between separating in the lateral direction Every forming 3 opening portion 46b.Expose a part of upstream side conveying roller 51 respectively from 3 opening portion 46b.Rear outer Front part in the top surface of shell 12 is respectively formed towards front side in the left and right sides across removing guiding element 7 and tilts downward Rake 122, between the rake 122 and the upper part of front side wall portion 46, a part expose in the state of configure Downstream side transport roller 54.That is, the conveying configuration of roller 54 in downstream side is in the left and right sides across transfer section W.Described 3 A upstream side conveying roller 51 is the driven roller for driving the rotation of roller 51a with upstream side shown in fig. 6 conveying and rotating. In addition, 2 downstream sides conveying rollers 54 be rotated with the rotation of downstream side shown in fig. 6 conveying driving roller 54a from Dynamic roller.

Removing guiding element 7 includes a pair of of side guiding element 72, and setting is arranged in across the left and right sides of transfer section W；And connection This is more being leaned on conveyance direction upstream side to link side guiding element 72 by guiding element 73 than transfer section W；And from front side, formed For the open substantially U-shaped in top.As shown in Figure 10, side guiding element 72 its front end portion from connection guiding element 73 front surface court After front side tilts and rises, upper part 721 rolls tiltedly backwards.The upper part 721 is to play the paper for avoiding being moved It opens P contact and interferes the part of the so-called evacuation effect of conveying.

In the present embodiment, that removes the front surface for linking guiding element 73 and side guiding element 72 in guiding element 7 removes upper end The front end portion other than 721 is divided to be equivalent to the guidance part G with a face contact of paper.In addition, in connection guiding element 73, in right and left Upward center portion forms flank 731, and the paper for being transported to connection guiding element 73 especially strongly connects with the flank 731 Touching.

As described above, removing guiding element 7 is the turn centered on shaft 71.In addition, removing guiding element 7 has as arc-shaped arrow Shown in head like that, the spring 74 (referring to Fig.1 2) that guidance part G is pressed towards another surface side R2.In addition, in Figure 10, spring 74 Glued dose of casket 3 covers.In Fig. 9 and Figure 10, transfer platen 52 shown in Fig. 7 is shown and is in backoff state, guidance part G is in Utilize the pattern of spring 74 exerted pressure towards the position advanced another surface side R2.In the state that guidance part G advances, guidance part G, which is located at, more leans on the side transport path R (being front side in figure, close to the side of transport path R) than transfer section W, to be able to prevent edge The paper that transport path R is moved is contacted with transfer section W.

On the other hand, when transfer platen 52 shown in Fig. 7 is changed into transfer state, and transfer platen 52 will be moved When paper P is clamped into it between transfer section W, removing guiding element 7 is pressed against paper P.Removing guiding element 7 fights spring 74 as a result, Turn toward the clockwise direction of exerting pressure, guidance part G from the position of advance shown in Fig. 9 retreat.That is, working as guidance part G When in retracted position, the paper moved is allowed to contact with transfer section W.In Fig. 9, removing is shown using circle encirclement The turn toward the clockwise direction of guiding element 7, guidance part G are in the pattern of retracted position.In addition, by the rear casing 12 in printer 1 Rear casing (part equal with platen roller 221 in printing mechanism) after being changed to the 2nd unit 10b of removal, and by Fig. 4 institute The front casing 13 shown is also changed to the front casing after removing the 1st unit 10a shown in fig. 6, can be used as not having as a result, viscous The printer 1 for connecing the transfer function of agent uses.

Then, detailed to being carried out using conveying roller conveying paper and to the paper transfer bonding agent transported using Figure 11 It describes in detail bright.

Figure 11 (a) is that transfer platen 52 is in transfer state from side and bonding agent S is transferred to the paper moved The figure opening the state of P and conceptually illustrating.In the Figure 11 (a), the upstream side conveying rolling in the center on left and right directions is shown Cylinder 51, it is to show its position by 2 chain lines that downstream side, which transports roller 54,.In addition, showing conveyance direction using straight arrows.Figure 11 (b) be the figure of the pattern from another surface side by conveying roller conveying paper, and Figure 11 (c) is from a surface side by transporting Roller transports the figure of the pattern of paper.In the Figure 11 (c), is surrounded by square and conceptually illustrate transfer section W.In addition, In Figure 11, removing guiding element is omitted.

It is right when transporting paper P with the state being clamped between transfer platen 52 and transfer section W as shown in Figure 11 (a) P1 transfers bonding agent S on one side.In Figure 11 (c), shows hatchedly and has been transferred the part S' of bonding agent S in one side P1, In the present embodiment, to the center portion of the paper width direction of paper P (direction orthogonal with paper conveyance direction) from turn Print portion W transfers bonding agent S.Herein, in the part for being transferred bonding agent S of paper P, load when migrating splicing tape T is generated Or for the load etc. from splicing tape T removing bonding agent S.Therefore, the part S' for being transferred bonding agent S of paper P and its left side The part of right two sides is compared, and has conveying to postpone and generate and transport undesirable worry.Therefore, using flat belt 53 by transfer platen 52 link with upstream side conveying driving roller 51a, and transfer platen 52 is also set as driving roller, is also generated in transfer section W as a result, Transport the power of paper P.Thereby, it is possible to inhibit the conveying of the part S' for being transferred bonding agent S of paper P to postpone.In addition, at this In embodiment, the flat belt 53 that connection transfer platen 52 transports driving roller 51a with upstream side is migrated, and thus can also be utilized The flat belt 53 transports paper P, can further avoid the conveying delay of the part S' for being transferred bonding agent S of paper P. Further, it is possible to steadily transporting paper P in the case where not making the curved situation of paper P transported using flat belt 53, and Flat belt 53 is also functioned as the supporting table when transfer section W transfers bonding agent S.

Herein, in the case where Fig. 2 or paper outlet 1a shown in Fig. 4 is blocked, following worry is had: not from paper Paper P is discharged in outlet 1a, which is rolled into the bonding of transfer section W in the state of bending and fold Band T, generates bonding agent casket 3 bad.Therefore, rolling is transported in the downstream side setting downstream side for more leaning on conveyance direction than transfer section W Cylinder 54.According to the aspect, even if generating in the undesirable situation of discharge of the paper P of paper outlet 1a, downstream side conveying Paper P also can be continued to transport by roller 54 towards paper outlet 1a, so the paper P of bending and fold can be prevented to be involved in To the splicing tape T of transfer section W.In addition, as shown in 2 chain lines in Figure 11 (b) and Figure 11 (c), also can with downstream side axle 541 at For the mode of the position in paper conveyance direction with transfer section W side by side, downstream side is set and transports roller 54.Under that is, As long as conveying is clamped in the position in the downstream side after transfer section W by trip side conveying roller 54.

In turn, as shown in Figure 11 (c), downstream side conveying roller 54 is not configured in the portion for being transferred bonding agent S of paper P Divide S'.That is, downstream side transport roller 54 by paper P except the part by transfer section W and by transfer section W after Partially conveying is clamped at the position other than the two parts.Therefore, adhesive-free is attached to downstream side conveying roller 54 and causes dirt The worry of dye.Thereby, it is possible to prevent the conveyings such as the paper jam generated because transporting glued dose of roller pollution bad.In addition, also examining Consider and the aspect that non-adhesive handles or sets bonding agent removal mechanism is implemented to downstream side conveying roller 54, but corresponds to this, device Cost will increase.In addition, it is also considered that periodically to be safeguarded, the burden that accompanying bonding agent is removed, but is safeguarded increases, thus It is not preferred.

In addition, the downstream side conveying clamping of roller 54 of present embodiment is cut off and transported by cut-off knife mechanism 23 shown in Fig. 4 Come paper P, and when paper P is stretched idle running, namely it is so-called have ampleness.As a result, in the conveyance direction of paper P The part in downstream side clamps the paper using downstream side conveying roller 54 in the state of paper outlet 1a (referring to Fig. 4 etc.) discharge P is opened, when paper P is stretched by user, downstream side transports roller 54 and dallies, so as to successfully take from paper outlet 1a Paper P out.

Figure 12 is for illustrating the figure from the state transferred to the transformation of non-transfer state.In Figure 12, (a-1), (b-1) and (c-1) is figure viewed from above, and (a-2), (b-2) and (c-2) is the figure from side.In addition, in Figure 12 In, (a-1) and (a-2) shows the pattern that transfer platen 52 is backoff state, and it is to turn that (b-1) and (b-2), which shows transfer platen 52, The pattern of print state, (c-1) and (c-2) show the pattern that transfer platen 52 is changed into backoff state from transfer state.In addition, In Figure 12, paper P is represented by dashed line in benefit, and the left side of figure becomes front side, and the right side of figure becomes rear side.

As shown in Figure 12 (a-1) and Figure 12 (a-2), in the case where transfer platen 52 is in backoff state, guiding element 7 is removed It being pressed by spring 74, guidance part G is in the position advanced towards another surface side, and the one side P1 of paper P is contacted with guidance part G, by This is guided in a manner of leaving transfer section W.It is able to prevent the one side P1 of paper P from contacting with transfer section W as a result,.In addition, paper P is sandwiched in position more farther than guidance part G by a pair of of downstream side conveying roller 54, so turning as shown in Figure 12 (a-1) being located at Part between the guidance part G of the left and right sides of print portion W applies tension and becomes the state being tensioned, in conveyance direction, As shown in Figure 12 (a-2), become the state along guidance part G.The state is non-transfer state, even if under the non-transfer state Paper P is transported, bonding agent will not be transferred to one side P1.

Next, when driving solenoid 61 (referring to Fig. 8), when transfer platen 52 is changed into transfer state, such as Figure 12 (b-1) And shown in Figure 12 (b-2), paper P is clamped between transfer section W and transfer platen 52.Removing guiding element 7 is pressed against paper as a result, P, and fight exerting pressure for spring 74, the turn toward the clockwise direction as shown in the circular arc shaped arrow of figure, guidance part G is from figure 12 (a-1) and the same position for scheming advance shown in (a-2) retreat.The state is transfer state, if removed under the transfer state Paper feeding P, then bonding agent is transferred to the one side of paper P just as Figure 11 is used hereinbefore to describe.Although in addition, It is not known in figure, but transports rolling in a pair of of downstream side at the position that a pair of of upstream side conveying roller 51 is sandwiched paper P Cylinder 54 sandwiches on the line of position connection of paper P, and the position that paper P is sandwiched between transfer section W and transfer platen 52 is in It is opposite side slightly retracted position towards the direction being pressed with removing guiding element 7.

Then, when driving solenoid 61, as shown in Figure 12 (c-1) and Figure 12 (c-2), transfer platen 52 is towards leaving transfer section The direction of W is mobile and when being changed into backoff state from transfer state, and removing guiding element 7 starts due to exerting pressure towards the inverse time because of spring 74 The turn of needle direction, guidance part G advance towards another surface side.Paper P guided portion G is pressed towards another surface side as a result, is had transferred Bonding agent S1 and non-transfer bonding agent S2 is easy disjunction (referring to Fig. 3 (b)).As a result, turning in transfer platen 52 from transfer state After becoming backoff state, paper P is changed into non-transfer state from the state transferred immediately.That is, although transfer Roller 52 is changed into backoff state, the shape that can also prevent non-transfer bonding agent S2 to be transferred to paper P and persistently transferred State.Therefore, by adjusting at the time of so that the transfer platen 52 is changed into backoff state from transfer state, being easy that bonding agent will be had transferred Length adjustment in the conveyance direction of S1 is required length.In addition, keeping out of the way although transfer platen 52 is changed into from transfer state State there will not be and transport paper P, paper P in the state of having transferred bonding agent S1 and non-transfer bonding agent S2 and not being broken Glued band T is involved in and causes to transport bad this worry.

Herein, in the present embodiment, as shown in Figure 12 (b-2), to pass through (the side being taken up splicing tape T of transfer section W To) set as 90 ° or more of mode with the angle a of the part by transfer section W of paper P.If using the aspect, So so-called paste is exhausted and can be made moderate progress, and is had transferred bonding agent S1 and non-transfer bonding agent S2 and is easier to be broken.In addition, In the present embodiment, since the movement of the plunger 611 of solenoid 61 (referring to Fig. 8) is very fast, so when transfer platen 52 is from turning When print state is changed into backoff state, paper P is not being contacted with the part wound on transfer platen 52 in flat belt 53 Under state, guided portion G is pressed to the side another side P2.

In addition, in the present embodiment, using when transfer platen 52 is changed into transfer state from backoff state, utilizing paper The aspect of P pressing guidance part G is opened, but can also be used makes the width dimensions of transfer platen 52 become larger and press using transfer platen 52 The aspect of guidance part G.

Figure 13 is the concept map for illustrating the part for guidance part contact of the one side of paper.Figure 13 be from Figure 11 (c) figure of corresponding surface side observation, becomes conveyance direction from the direction underneath towards top of figure, the left and right directions of figure becomes Paper width direction.

In the Figure 13, the ratio in the part for guidance part G contact of the one side P1 of paper P is transferred viscous by transfer section W The transfer section for connecing agent more leans on the downstream side part Y1 in conveyance direction downstream side to draw the hachure declined to the left, to from transfer section The part Y2 arranged side by side deviated towards paper width direction draws lateral hachure, and the upper of conveyance direction upstream side is more being leaned on than transfer section Trip side section Y3 draws the hachure declined to the right.

Downstream side part Y1 be equivalent to paper P from a part by the paper width direction after transfer section W towards paper P Paper width direction offset part.It is contacted by guidance part G with downstream side part Y1, in transfer platen 52 from transfer state When being changed into backoff state, it is easier to make to have transferred bonding agent S1 and non-transfer bonding agent S2 disjunction.

Herein, in the case where transfer platen 52 is in transfer state, there is the part by transfer section W of paper P Transfer bonding agent S1 and non-transfer bonding agent S2 is not broken, and the situation that the conveying for generating paper P is bad.In present embodiment In, even if being contacted, being transferred with downstream side part Y1 by guidance part G in the case where transfer platen 52 is in transfer state Under state, be also easy to make the part by transfer section W of paper P has transferred bonding agent S1 and non-transfer bonding agent S2 disjunction.

In turn, it prevents with the one side P1 for being transferred bonding agent for the paper P being discharged from paper outlet 1a as lower inclination Tiltedly, such as it can be avoided the unfavorable condition for being attached to exterior face of printer 1 etc.In addition, in the present embodiment, making Fig. 4 Shown in from the transport path R of paper that paper outlet 1a is discharged roll oblique 15 degree or so forward relative to vertical direction.I.e. Make the paper P according to making the inclined aspect in the side facing forward transport path R, being discharged from paper outlet 1a be also not easy be with one side P1 Downside inclination.However, making that transport path R is rolled tiltedly forward due to generating, what the setting area of device was bigger etc is asked Topic, so transport path R is made to roll the range that oblique etc countermeasure can be limited in the setting area of allowed device forward It is interior.In the present embodiment, inhibit the setting of device by using the guidance part G that the downstream side part Y1 with paper P is contacted The expansion of area, and can prevent from gluing with being transferred for paper P being discharged from paper outlet 1a using simple composition The one side P1 of agent is met as downside inclination.
