The

  Next, an example of the paper guide mechanism unit 7 of the printer 1 will be described with reference to FIGS. 4 is a schematic view of the main part of the printer shown in FIG. 1 with the opening / closing cover part closed, viewed from the side, and FIG. 5 is the main part of the printer shown in FIG. FIG. 6A is a main part configuration diagram in which the engaging part between the operation plate for operating the guide plate and the outer case in the printer of FIG. 4 is viewed from the opening / closing cover part side, and FIG. 6B. FIG. 7 is a configuration diagram of the main part of the engagement portion between the operation plate for operating the guide plate and the external case in the printer of FIG. 5 as viewed from the opening / closing cover portion side, and FIG. 7 is a view of the printer of FIG. FIG. 4 is an enlarged perspective view of a main part of a paper guide mechanism unit.

  The paper guide mechanism unit 7 includes a pair of guide plates 7a and 7a, an operation plate 7b, and a guide plate moving mechanism unit 7c (see FIG. 7). The pair of guide plates 7a, 7a are installed with their inner side surfaces facing each other. Each of the guide plates 7a, 7a is formed in a substantially circular plane shape, for example, and is installed in a state where it can move in a direction approaching and separating from each other by the guide plate moving mechanism portion 7c.

  The guide plate moving mechanism portion 7c is a mechanism portion for moving the pair of guide plates 7a, 7a toward and away from each other. As shown in FIG. 7, the pair of leg portions 35, 35, Rack portions 36 and 36 and a pinion gear portion 37 are provided. Each leg part 35 and 35 is a part which supports each guide plate 7a and 7a, and is integrally molded by each guide plate 7a and 7a. Rack portions 36, 36 are integrally formed on the inner side surfaces of the leg portions 35, 35. Each rack part 36, 36 extends from one leg part 35, 35 toward the other leg part 35, 35 and is installed in a state of facing each other. Between the opposing surfaces of the rack portions 36, 36, a pinion gear portion 37 is installed so as to be rotatable along the installation surface of the guide plate 7a. The rack portions 36 and 36 and the pinion gear portion 37 include a plurality of teeth (unevenness) 36 a formed along the extending direction of the rack portion 36 on the facing surfaces of the rack portions 36 and 36, and a pinion gear portion 37. A plurality of teeth (unevenness: not shown) formed along the outer periphery of each other are engaged with each other. By providing such a guide plate moving mechanism portion 7c, when one guide plate 7a is moved in the width direction of the label continuous body P, one rack portion 36 connected to one guide plate 7a is also moved in the same direction. Therefore, as a result of the rotation of the pinion gear portion 37 engaged with the rack portion 36, the other rack portion 36 engaged with the pinion gear portion 37 also moves, so that the other connected to the other rack portion 36 The guide plate 7a also moves in the direction opposite to the moving direction of the one guide plate 7a. For this reason, since the label continuum P can be held at an appropriate position in accordance with the width thereof, the label continuum P can be transported in a stable posture.

  As described above, the operation plate 7b is a member that operates to fix, release, and move the guide plate 7a. One end of the operation plate 7b is movably engaged with the opening / closing cover 3. That is, a pair of projecting portions 40, 40 projecting in the width direction of the operation plate 7b (the conveying direction of the label continuous body P) are formed on both side surfaces in the width direction of one end portion of the operation plate 7b. 40 and 40 are fitted in the groove 41 on the back surface of the opening / closing cover 3. The groove 41 extends along the width direction of the label continuous body P. Thereby, the operation plate 7b is engaged with the opening / closing cover part 3 in a state in which the operation plate 7b is movable along the width direction of the label continuous body P.

  The operation plate 7b is also movably engaged with the guide plate 7a. That is, a plurality of support portions 42 are distributed on the outer side surface of one guide plate 7a, and the operation plate 7b is movable along the side surface of the guide plate 7a by the plurality of support portions 42. It is supported by the guide plate 7a. As a result, the opening / closing cover 3 can be opened and closed in a state where the operation plate 7b is engaged with the guide plate 7a.

  According to this structure, when the opening / closing cover part 3 is opened, the operation plate 7b also moves following the movement of the opening / closing cover part 3. At this time, since the opening / closing cover 3 cannot be opened if the operation plate 7b is formed in a straight line, the operation plate 7b is formed in a curved shape so that the opening / closing cover 3 can be opened and closed. . Thus, as shown in FIG. 5, when the open / close cover portion 3 is opened, the central portion of the operation plate 7b projects in an arch shape between the open / close cover portion 3 and the guide plate 7a. The guide plate 7a engaged with the operation plate 7b can be easily moved in the width direction of the label continuous body P by picking the protruding portion of the plate 7b with a finger and moving it in the width direction of the label continuous body P. . Therefore, the operability of the guide plate 7a can be improved.

  An engaging portion (fixed portion) 43A is formed integrally with the operation plate 7b at the other end of the operation plate 7b. As shown in FIGS. 6 and 7, the engaging portion 43A of the operation plate 7b is formed with a plurality of irregularities along the thickness direction of the operation plate 7b (the width direction of the label continuous body P). On the other hand, as shown in FIGS. 4 and 5, the side surface (surface intersecting the facing surface of the opening / closing cover 3) S1 in the outer case 2 on the back side of the printer 1 is engaged with the side surface S1 as shown in FIG. A portion 44A is formed. A plurality of projections and depressions are formed in the engaging portion 44A in the outer case 2 along the width direction of the label continuous body P so as to be fitted into the plurality of projections and depressions of the engaging portion 43A of the operation plate 7b. . As shown in FIG. 4, when the open / close cover portion 3 is closed, as shown in FIG. 6A, the engaging portion 43A of the operation plate 7b approaches the engaging portion 44A in the outer case 2 and engages with each other. By joining, the guide plate 7a is fixed. On the other hand, as shown in FIG. 5, when the opening / closing cover part 3 is opened, the engaging part 43A of the operation plate 7b is separated from the engaging part 44A of the outer case 2 as shown in FIG. The fixed state of is released. 6A and 6B, the arrow A5 indicates the moving direction of the operation plate 7b when the opening / closing cover 3 is opened / closed.

  As described above, the operation plate 7b is engaged with both the opening / closing cover portion 3 and the guide plate 7a and moves in accordance with the operation of the opening / closing cover. Therefore, when the opening / closing cover portion 3 is closed, the guide plate 7a is automatically set. When the opening / closing cover 3 is opened, the fixed state of the guide plate 7a is automatically released. For this reason, the operation of fixing and releasing the guide plate 7a can be facilitated, and the cover is not closed in the released state. Therefore, the operability of the guide plate 7a can be improved. In addition, since it is possible to prevent the pair of guide plates 7a and 7a from being forgotten to be fixed, the label continuum P can be transported in a state in a stable posture during printing.

  As shown in FIGS. 4, 5, and 7, in the vicinity of the engaging portion 43 </ b> A of the operation plate 7 b, it penetrates between both surfaces in the thickness direction of the operation plate 7 b (width direction of the label continuous body P). And the hole (elastic deformation structure) 45 extended in the width direction of the operation board 7b is formed. When the engaging portion 43A of the operating portion 7b and the engaging portion 44A in the outer case 2 are engaged, the operating plate between the hole 45 and the engaging portion 43A is bent, whereby the engaging portion of the operating plate 7b. Since an action like a leaf spring can be generated in the vicinity of 43A, the engagement state between the engagement portion 43A of the operation plate 7b and the engagement portion 44A in the outer case 2 is fine so as not to occur. Can be adjusted. Further, it is possible to absorb a dimensional error in the longitudinal direction of the operation plate 7b and the like.

Here, a case has been described in which the operation plate 7b and the engaging portions 43A and 44A in the outer case 2 are provided with concavities and convexities, and both are fitted, but the present invention is not limited to this, and the operation plate 7b and Without providing irregularities on the engaging portions 43A and 44A in the outer case, the other end in the longitudinal direction of the operation plate 7b is pressed against the side surface S1 in the outer case 2, and the guide plate 7a is fixed by the frictional force at that time. It may be configured. Thereby, since the alignment accuracy of the unevenness of the engaging portion 43A of the operation plate 7b and the unevenness of the engaging portion 44A of the outer case 2 can be relaxed, the structure of the printer 1 can be simplified. Further, since it is not necessary to form irregularities for fitting on the operation plate 7b and the outer case 2, the cost of the printer 1 can be reduced.
In order to increase the frictional force, a material having a high friction coefficient such as rubber may be used for the other end of the operation plate 7b.

  Next, an example of a method for accommodating the label continuous body P in the paper accommodating portion 6 of the printer 1 will be described with reference to FIGS. 1 and 5 to 7. First, when the cover open button Bp of the printer 1 shown in FIG. 1 is pressed, the open / close cover portion 3 is automatically opened by a torsion spring disposed on the open / close support shaft. Then, the operation plate 7b engaged with the open / close cover portion 3 also moves along the side surface of the one guide plate 7a following the movement of the open / close cover portion 3. For this reason, as shown in FIG. 6B, the engaging portion 43A of the operation plate 7b is separated from the engaging portion 44A of the outer case 2, so that the fixed state of the pair of guide plates 7a and 7a is automatically released. The A part of the operation plate 7b protrudes in an arch shape between the opening / closing cover portion 3 and the one guide plate 7a.

  Subsequently, a part of the operation plate 7b protruding between the opening / closing cover portion 3 and the one guide plate 7a is picked by a finger, and the operation plate 7b is moved in the thickness direction thereof, thereby a pair of guide plates 7a. , 7a so that the label continuum P can be accommodated. At this time, when one guide plate 7a is moved in one direction by operating the operation plate 7b, one rack portion 36 (see FIG. 7) connected to the guide plate 7a is also moved in the same direction, so that the pinion gear portion 37 is moved. As a result, the other rack portion 36 engaged with the pinion gear portion 37 moves in the reverse direction, so that the other guide plate 7a connected to the other rack portion 36 moves in the reverse direction (one guide plate 7a). In a direction away from

  Subsequently, after the label continuum P is accommodated between the pair of guide plates 7a and 7a of the paper accommodating portion 6, the operation plate 7b is operated in the same manner as described above, whereby the pair of guide plates 7a and 7a is moved to the label continuum. The label continuous body P is supported by moving it to a position where it contacts both end faces of the width direction of P. In the present embodiment, a part of the operation plate 7b protrudes between the open / close cover portion 3 and the one guide plate 7a, that is, above the label continuum P. Since the guide plate 7a can be moved by moving the operation plate 7b in the width direction of the label continuum P even after being accommodated, the position of the guide plate 7a is easily adjusted to match the width of the label continuum P. be able to.

  Thereafter, when the opening / closing cover 3 is closed, the engaging portion 43A of the operation plate 7b approaches and engages with the engaging portion 44A of the outer case 2 following the movement of the opening / closing cover 3, so that the pair of guide plates 7a and 7a can be automatically fixed. For this reason, since it is possible to prevent the pair of guide plates 7a, 7a from being forgotten to be fixed, the label continuum P can be transported in a state of being stabilized in printing. Here, in the technology studied by the inventor, there is a structure in which the guide plate 7a is fixed and released by moving the operation unit up and down, but the guide plate 7a is close to the inner side surface of the outer case 2. In addition, it is difficult to put a finger between the operation unit and the inner side surface of the outer case 2, and the operation unit may be difficult to operate. For this reason, a gap for inserting a finger must be ensured between the operation unit and the outer case 2, which may hinder downsizing of the printer. On the other hand, in the present embodiment, the guide plate 7a can be unfixed and fixed by opening and closing the open / close cover portion 3, so it is necessary to secure a gap for inserting a finger between the operation plate 7b and the outer case 2. No. For this reason, the printer 1 can be reduced in size.
