  Next, the internal structure of the printer 1 will be described with reference to FIG. FIG. 8 is a schematic configuration diagram showing the inside of the printer of FIG.

  As shown in FIG. 8, in the frame part F accommodated in the opening 2a of the main body case 2, as a mechanism for printing on the label PL of the continuous paper P, a head bracket 27 and a thermal head 28 (FIG. 12), a coil spring 29 (see FIG. 12), and a battery housing portion 33.

  The head bracket 27 is a member that holds the open / close cover portion 3 in a closed state. The head bracket 27 is disposed on the frame portion F described above so as to be swingable about the rotation shaft 27a on the opposite side of the platen roller 10 when the open / close cover portion 3 is closed.

  The head bracket 27 is formed with a groove 27b. The opening / closing cover portion 3 is held by the head bracket 27 by fitting the platen shaft 10a of the platen roller 10 into the groove 27b.

  The head bracket 27 is formed with a pressing portion 27c. The pressing portion 27 c is disposed at a position (directly below) facing the cover open button 18 shown in FIG. 1. When the cover open button 18 is pressed, the pressing portion 27 c is also pressed, and the opening / closing cover portion 3 by the head bracket 27. The holding state is released. When the holding state of the opening / closing cover 3 is released, the opening / closing cover 3 is automatically opened by the urging force of the torsion spring 35 disposed on the other end in the longitudinal direction.

  The thermal head 28 is a printing unit that prints information such as characters, symbols, figures, or barcodes on the label PL. For example, the thermal head 28 faces the platen roller 10 when the opening / closing cover 3 is closed. The print surface is mounted on the head bracket 27 via the circuit board 36 in a state where the print surface faces the paper route. On the printing surface of the thermal head 28, a plurality of heating resistors (heating elements) that generate heat when energized are arranged side by side along the width direction of the continuous paper P (short direction of the mount PM). The circuit board 36 is a wiring board that transmits a print signal to the thermal head 28.

  The coil spring 29 (see FIG. 12) is a member that urges the head bracket 27 and the thermal head 28 toward the platen roller 10 when the open / close cover portion 3 is closed, and the back side of the head bracket 27 (on the mounting surface of the circuit board 36). It is installed on the back side. Since the head bracket 27 is pushed toward the platen roller 10 by the urging force of the coil spring 29, the platen shaft 10a fitted in the groove 27b of the head bracket 27 is also firmly pressed, and the opening / closing cover portion 3 is held by the head bracket 27. State is maintained.

  The battery accommodating portion 33 is a location where the battery is accommodated. The battery is accommodated in the battery accommodating portion 33 and connected to an electrode (not shown), whereby the stepping motor M, the thermal head 28, and the control board unit 40 ( When the power button 17 is turned on, the power is supplied to the sensor 12, the display unit 15, the operation buttons 16a and 16b, and the like.

  As shown in FIGS. 3 and 8, the control board unit 40 is attached to the side of the frame F opposite to the attachment position of the opening / closing cover part 3. The control board unit 40 is mounted with an electronic board for controlling the operation of the printer 1, and according to the contents of the input operation using the operation buttons 16 a and 16 b by the operator and the detection information of the sensor 12. For example, the rotation operation of the platen roller 10 is controlled via the stepping motor M, and for example, the printing operation of the thermal head 28 for printing on the label PL is controlled.

  As described above, the printer 1 according to the present embodiment modularizes the functional unit portion Y having a printing function as a configuration independent of the casing of the main body case 2 and the front cover portion 5 so as to protect the functional unit portion Y. Thus, the main body case 2 and the front cover 5 are fixed.

  Therefore, when the printer 1 is assembled, the frame part F is modularized by assembling functional parts such as the opening / closing cover part 3, the platen roller 10, the thermal head 28, the peeling unit 4, and the control board unit 40. Functional unit portion Y is obtained. That is, the functional unit portion Y is completed by assembling functional parts such as the platen roller 10 from various arbitrary directions to the base frame portion F.

  Therefore, when the main body case 2 is used as a base, the workability at the time of assembling the printer 1 is improved as compared with the case where the assembly is difficult because the functional parts have to be incorporated into the box called the main body case 2. To do.

  Further, in the printer 1 according to the present embodiment, functional parts such as the opening / closing cover portion 3, the platen roller 10, the thermal head 28, the peeling unit 4, and the control board unit 40 are assembled to the frame portion F serving as a base. Therefore, when assembling the functional parts in order, the positional accuracy between the parts constituting the printer 1 is improved compared to the deterioration of the positional precision between the parts due to the accumulated tolerance of the functional parts. Is possible.

  Furthermore, since the printer 1 according to the present embodiment is configured with the functional unit unit Y by assembling functional parts such as the opening / closing cover unit 3 and the platen roller 10 to the frame unit F, printing is performed only by the functional unit unit Y. The action can be performed. For example, in the printer 1 of the present embodiment, the opening / closing cover portion 3 provided with the platen roller 10 is in the functional unit portion Y, and the thermal head 28 is at a position facing the platen roller 10 when the opening / closing cover portion 3 is closed. Therefore, the printing operation can be performed by switching between the peeling issue and the continuous issue.

  Therefore, since the operation check (test operation) at the time of manufacturing the printer 1 can be performed in the middle of the completion of the printer 1, it is possible to check the malfunction of the operation at that time and easily execute the countermeasure for the malfunction. it can.

  And since the battery accommodating part 33 is formed in the flame | frame part F, the wiring routing length from a battery can be shortened.

  Next, the mounting structure of the main body case 2, the functional unit portion Y, and the front cover portion 5 will be described with reference to FIGS. 4 and 9 to 11. FIG. 9 is a bottom view of the main body case, FIG. 10 is a bottom view of the functional unit portion, and FIG. 11 is a front view of the functional unit portion as viewed from the direction in which the control board unit is attached.

  In the present embodiment, as described above, the main body case 2 and the front cover portion 5 are fixed at four positions with screws, thereby sandwiching the functional unit portion Y.

  As shown in FIG. 9, four screw holes 50 into which screws for fixing the main body case 2 and the front cover portion 5 are inserted are formed on the back surface of the main body case 2. Specifically, two screw holes (first screw holes) 50a are provided on both sides of the paper storage unit side, and two screw holes (second screw holes) are provided on both sides of the display unit side (that is, opposite to the paper storage unit 6). Screw holes) 50b are respectively formed. Two screw through holes 50c through which screws for attaching printer carrying members such as belt clips and shoulder belts (not shown) pass are formed inside the screw holes 50b.

  As shown in FIG. 4, guide cylinders 51a and 51b for guiding the insertion direction of the screws inserted into the screw holes 50a and 50b are provided near the side walls of the opening 2a of the main body case 2 and the screw holes 50a and 50b. Each is formed in communication.

  Further, as shown in FIGS. 4 and 10, guides corresponding to the screw holes 50 a when the functional unit portion Y is housed in the main body case 2 are disposed at both ends in the short direction of the frame portion F constituting the functional unit portion Y. A rib (plate-like piece) 52 is formed in contact with the distal end surface of the cylinder 51a. The rib 52 has a through hole 52a through which a screw inserted into the screw hole 50a and protruding from the guide tube 51a passes.

  Further, a stepped portion 2b having a height higher than that of the periphery is formed on the bottom surface of the opening 2a of the main body case 2 in the vicinity of the guide tube 51b. The frame portion F is formed with a flange 53 that comes into contact with the step portion 2b when the functional unit portion Y is stored in the main body case 2.

  Therefore, on the sheet storage unit side, the main unit case 2 and the front cover unit 5 are sandwiched between the main unit case 2 and the front cover unit 5 and the main unit case 2 and the front cover unit via the frame unit F by screws that pass through the through holes 52a of the frame unit F. 5 is fixed. On the other hand, on the display unit side (opposite side of the paper storage unit 6), the main unit case 2 and the front cover unit 5 are directly fixed by screws with the functional unit unit Y sandwiched between the main unit case 2 and the front cover unit 5. Is done.

  The stored functional unit portion Y is not in a state where the bottom surface thereof is in contact with the main body case 2 without a gap, but the rib 52 of the frame portion F is in contact with the tip of the guide tube 51a, and the flange 53 is a stepped portion. By coming into contact with 2b, a gap is formed between the main body case 2 and the functional unit portion Y. In addition, you may put the buffer material for absorbing a drop impact etc. in the said clearance gap.

  Then, when an external force such as a drop impact is applied due to such a gap, the external force is absorbed by deformation of the main body case 2 and the like, and thus it is difficult to be transmitted to the functional unit portion Y. Therefore, the occurrence of misalignment between components attached to the frame portion F due to external force is alleviated, and replacement when the main body case 2 is damaged is facilitated.

  As a screw for fixing the main body case 2 and the front cover portion 5, for example, a tap screw having a notch at the tip can be used. In this case, a screw groove is formed in the screw receiving hole by closing the screw tip while being pushed into a screw receiving hole (not shown) formed inside the front cover portion 5.

  As shown in FIGS. 10 and 11, a metal carrying member fixing plate in which two screw holes 54 a for screwing a printer carrying member such as a belt clip or a shoulder belt are formed so as to straddle the flange 53. A (carrying member fixing plate) 54 is attached to the frame portion F. The screw hole 54a is formed at a position facing the screw through hole 50c formed in the main body case 2 described above, and the screw inserted from the screw through hole 50c is tightened into the screw hole 54a. As shown in detail in FIG. 11, the carrying member fixing plate 54 has both ends in the longitudinal direction fitted in the frame portion F, and can be elastically deformed like a leaf spring.

  Therefore, when the belt clip or the like is attached to the carrying member fixing plate 54, the vibration transmitted through the belt clip or the like due to the movement of the operator is greatly absorbed by the elastic deformation of the carrying member fixing plate 54. As a result, vibration is not directly transmitted to the frame portion F or the opening / closing cover portion 3 attached to the frame portion F, the platen roller 10, the thermal head 28, the peeling unit 4, the control board unit 40, etc. Occurrence of defects caused by

  Next, continuous issue and release issue of the printer 1 will be described with reference to FIGS. 12A is a schematic configuration diagram of the printer at the time of continuous issuance in FIG. 1A, and FIG. 12B is a schematic configuration diagram of the printer at the time of issuance of peeling in FIG. 1B.

  In both the case of continuous issuance and release issuance, in the printing process, the platen roller 10 is rotated while the continuous paper P fed from the paper storage unit 6 is sandwiched between the thermal head 28 and the platen roller 10. The continuous paper P is conveyed. During this conveyance, the print timing is determined based on the information detected by the sensor 12, and the heating resistor of the thermal head 28 is selectively heated by the print signal transmitted to the thermal head 28, whereby the label PL of the continuous paper P is obtained. Desired information is printed.

  Here, in the continuous issue, the peeling unit 4 is disposed at the continuous issue position inside the printer 1 as shown in FIG. The printed label PL is discharged without being peeled off from the mount PM. In the case of continuous issuance, the mount PM with the required number of labels PL attached thereto can be created and the label PL can be peeled off and attached from the mount PM in the field. Suitable for remote locations.

  On the other hand, in the peeling issue, as shown in FIG. 12B, the peeling unit 4 is arranged at the peeling issuing position, and the mount PM is placed between the nip roller 4 a of the peeling unit 4 and the platen roller 10 via the peeling pin 11. Put it in between. Thus, when the platen roller 10 is rotated for printing and the continuous paper P is conveyed, the mount PM is conveyed in a state of being sandwiched between the nip roller 4a and the platen roller 10, while the label PL after printing is provided for each sheet. Is peeled off from the mount PM and discharged outside the machine. In the case of peeling issuance, the labels PL are discharged one by one, which is suitable when the object to which the label PL is attached is near the operator.

  In the printer 1 according to the present embodiment, it is possible to switch between continuous issue and release issue, and it is possible to deal with two situations, the case where the object to which the label PL is attached is close to the printer 1 and the case where it is far from the printer 1, with one unit. Convenient and economical.

  As mentioned above, the invention made by the present inventor has been specifically described based on the embodiment. However, the embodiment disclosed in this specification is an example in all respects and is limited to the disclosed technology. It should be considered not a thing. That is, the technical scope of the present invention should not be construed restrictively based on the description in the above-described embodiment, but should be construed according to the description of the scope of claims. All modifications are included without departing from the technical scope equivalent to the described technique and the gist of the claims.

  For example, in the above-described embodiment, the case where the present invention is applied to a combined type printer that can be used for both continuous issue and release issue has been described. However, the present invention is not limited to this, and only release issue or only continuous issue is possible. It can also be applied to a printer that can only be used.

  Further, in the above-described embodiment, the case where continuous paper in which a plurality of labels are temporarily attached to a mount is used as a print medium is not limited to this. For example, an adhesive surface is provided on one side. It is also possible to use, as a printing medium, a continuous label (a label without a mount), a continuous sheet (continuous sheet) without an adhesive surface, a film that can be printed by a thermal head, and the like. A label without a mount, a continuous sheet or a film can be provided with a position detection mark. Further, when carrying a non-mounting label where the adhesive is exposed, a non-adhesive roller containing silicone or the like can be provided while the conveyance path is covered with the non-adhesive.

  In the above description, the case where the present invention is applied to a stand-alone printer in which an input operation to the printer is performed without using a personal computer is not limited to this.
