Definitions

  • the present invention relates to a printer in which a platen roller and a recording head are separably combined with each other.
  • printers in which a recording head and a platen roller held in contact with the recording head are provided inside a casing, and in which the recording head performs recording onto a recording sheet sent out by the platen roller.
  • the recording head and the platen roller remain in contact with each other inside the casing. Thus, workability is poor.
  • the recording head and the platen roller can be spaced apart from each other so as to be exposed to an outside of the casing.
  • the recording head includes a plurality of recording elements (heat-generating elements or the like), and hence it is preferred that the recording head be fixed on a casing side in order not to impair reliability of electrical connections into which recording signals for selectively driving the recording elements are input.
  • the platen roller be spaced apart from the recording head so as to be exposed to the outside, with the recording head being fixed on the casing side.
  • a printer which includes a regulating member and a stationary frame, in which a platen roller can be easily attached and detached with use of those members, and in which the platen roller can be retained with high reliability while the platen roller is prevented from being inadvertently disengaged at the time of mounting (refer to JP 4376816 B ).
  • the regulating member includes a connecting portion into which a shaft portion of the platen roller is fitted, and the regulating member is undisengageably combined with the platen roller through intermediation of the connecting portion. Meanwhile, the regulating member is rotatably combined coaxially with and relatively to the platen roller. Note that, regarding movement except the relative rotation, the regulating member moves integrally with the platen roller. Further, the regulating member is provided with a protrusion-like engagement portion.
  • the stationary frame is fixed to a base of a casing, and includes a first recess and a second recess.
  • the first recess is a recess for positioning the platen roller to a recordable position by bringing the platen roller into contact with the recording head when the shaft portion of the platen roller is inserted.
  • the second recess is a recess for retaining a protrusion of the stationary frame when the protrusion is inserted under a state in which the shaft portion of the platen roller is inserted in the first recess.
  • the shaft portion of the platen roller is inserted in the first recess and retained therein, and then the regulating member is rotated relatively to the platen roller and the protrusion is inserted into the second recess and retained therein. With this, at the recordable position at which the platen roller is held in contact with the recording head, the platen roller can be reliably retained.
  • the printer is designed so that the platen roller is less liable to be inadvertently disengaged.
  • the platen roller can be retained with high reliability.
  • the platen roller when the platen roller is detached, the regulating member is rotated relatively to the platen roller (rotated in a direction reverse to that in the above-mentioned case). Consequently, the protrusion is disengaged from the second recess, and then the shaft portion of the platen roller is disengaged from the first recess. In this manner, the platen roller can be detached.
  • the platen roller can be attached and detached with a simple manipulation of rotating the regulating member so that the protrusion is inserted into or disengaged from the second recess.
  • the printer is excellent in manipulation properties of attachment and detachment.
  • the printers be structured as simply as possible and components be designed to be small.
  • the platen roller for feeding the recording sheet is larger among the components of the printers, and hence occupies a large space in the printer.
  • downsizing of the printer is efficiently achieved through possible reduction of a diameter of the platen roller.
  • the connecting portion of the regulating member is coaxially fitted into the shaft portion of the platen roller. Accordingly, when the diameter of the platen roller is reduced, it is necessary to reduce an outer diameter of the connecting portion in accordance therewith.
  • it is structurally necessary to secure a certain outer diameter Accordingly, it is practically difficult to further reduce the diameter of the platen roller at present.
  • the present invention has been made in view of such circumstances. It is therefore an object of the present invention to provide a printer in which the attachment and detachment manipulation of the platen roller can be easily performed, in which the platen roller can be retained with high reliability at the time of attachment, and in which downsizing of the entire printer is easily achieved due to use of the platen roller smaller in diameter.
  • the present invention provides the following measures for achieving the above-mentioned object.
  • a printer 1 As illustrated in FIGS. 1 and 2 , a printer 1 according to this embodiment includes a platen unit 2 and a main unit 3 which are separably combined with each other and a casing 4 for accommodating a sheet roll R formed of a wound recording sheet P.

  • the casing 4 includes a base member 10 and a lid member 11 openably and closably (rotatably) coupled to the base member 10 through intermediation of a rotary shaft 12.
  • the base member 10 is made of a resin material or the like in a box shape and an upper side thereof is open so that the sheet roll R is accommodated therein.
  • the lid member 11 is made of a resin material as well as the base member 10, and functions to expose an opening of the base member 10 in an opened state and cover the opening of the base member 10 in a closed state. Note that, locking and unlocking of the lid member 11 is effected by attachment and detachment of the platen unit 2 and the main unit 3.
  • the lid member 11 is formed to extend outward beyond the base member 10 (to the left side of the drawing sheets of FIGS. 1 and 2 ), and the platen unit 2 is fixed to an inner surface of the extended part.
  • a distal end portion 11a of the lid member 11 extending outward beyond the base member 10 is curved downward, and covers a part of the platen unit 2 from the outside.

  • the rocking members 22 are arranged in a manner of sandwiching the platen roller 21, and each has a root side rotatably coupled to a coupling pin 20c projecting in the direction parallel to the platen axis L1 from a corresponding side of the platen frame 20. With this, the rocking members 22 are rockable about the coupling pins 20c.
  • the bearing portions 22a are formed on distal end sides of the rocking members 22, and axially support the platen shaft 21 a projecting from both the end portions of the platen roller 21. With this, the platen roller 21 is axially supported by the rocking members 22 and coupled to the platen frame 20 through intermediation of the rocking members 22.
  • each of the rocking members 22 there is formed a rotary shaft portion 22b projecting to the platen roller 21 side along a rotary axis L2 that is non-coaxial with and parallel to the platen axis L1.
  • the rotary shaft portion 22b functions as a shaft portion to which a coupling plate 31 of the latch member 23 described later is rotatably fitted in a covering manner.
  • a driven gear 25 is fixed on one side of the platen shaft 21 a with one of the rocking members 22 being interposed between the driven gear 25 and the platen roller 21.
  • the driven gear 25 is rotated by a rotational force transmitted thereto when the platen unit 2 and the main unit 3 are combined with each other and the driven gear 25 meshes with a platen gear train 50 described later.

Specifically, each of the torsional springs 35 is fitted in a covering manner to a supporting pin 20d formed on the platen frame 20 side, and has one end side fitted into a groove portion 20e formed on a root side of the supporting pin 20d and another end side held in back-to-back contact with the base portion 30 of the latch member 23 so as to urge the latch member 23. With this, the latch member 23 is maintained under a state of being urged to be rotated about the rotary axis L2 in the locking direction D1.
  • the first stopper claw 20a and the engaging protrusion 31 b function as a regulating member 36 for regulating the rotational amount of the latch member 23 urged by the torsional springs 35.
  • rocking members 22 may rock in the locking direction D1 together with the latch member 23 urged by the torsional springs 35, a rocking amount in the locking direction D1 is regulated because the rocking members 22 come into contact with the second stopper claw 20b formed on the platen frame 20 side. That is, prior to the combination of the platen unit 2 and the main unit 3, the platen roller 21 is designed not to be excessively moved to the distal end portion 11a side of the lid member 11.

  • the manipulation lever 14 is formed in a J-shape in side view, and includes a manipulation end 14a formed on a distal end side thereof positioned on the distal end portion 11a side of the lid member 11. Meanwhile, a proximal end side of the manipulation lever 14 is coupled to the lid member 11 through intermediation of the rotary shaft 13, and the claw portions 14b extend, on an inner surface side of the lid member 11, from the coupled portion to the latch member 23.
  • the claw portions 14b are held in contact with the base portion 30 while intruding into the recesses 30a formed in the base portion 30 (refer to FIG. 3 ).
  • the claw portions 14b are held in contact with the base portion 30, and hence, when the manipulation lever 14 is subjected to a pulling-up manipulation (opening manipulation) through intermediation of the manipulation end 14a, the manipulation lever 14 is rotated about the rotary shaft 13 so that the claw portions 14b press the base portion 30 to the platen frame 20 side. With this, the latch member 23 is rotated about the rotary axis L2 in the release direction D2 in which the fixing pin 31 a comes close to the platen frame 20.
  • the main unit 3 includes a stationary frame 40 fixed to the base member 10 and a thermal head (recording head) 42 fixed to the stationary frame 40 through intermediation of a head support body 41, and is arranged so as to face the platen unit 2.

Then, when the lid member 11 is still further closed from this state, as illustrated in FIG. 9 , the fixing pin 31 a is automatically inserted and fitted into the second recess 46.

  • the fixing pin 31a can be smoothly fitted into or disengaged from inside the second recess 46 almost without being caught, and hence the attachment and detachment manipulation of the platen roller 21 can be smoothly performed.
  • the rotary shaft portion 22b projects to the platen roller 21 side, and hence the latch member 23 can be coupled to the rocking members 22 under a state of being positioned on the same side as that of the platen roller 21. If the latch member 23 is positioned on the side opposite to the platen roller 21 with the rocking members 22 being interposed therebetween, it is necessary to take a thickness of the rocking members 22 into consideration. Thus, a length of the printer 1 parallel to the platen axis L1 is liable to be elongated in the lateral width direction. However, the latch member 23 may be positioned on the same side as that of the platen roller 21, and hence the printer 1 is easily downsized without such a risk.
  • the lid member 11 can be opened and closed in conjunction with the attachment and detachment manipulation of the platen roller 21, and hence the printer 1 is easy to use.
  • the recording sheet P drawn out from the sheet roll R can be easily set between the platen roller 21 and the thermal head 42.
  • the locking and unlocking of the lid member 11 is performed simultaneously with the attachment and detachment of the platen roller 21.
  • the latch member 23 can be rotated through intermediation of the manipulation lever 14, and hence the attachment and detachment manipulation of the platen roller 21 can be more easily performed.
  • the manipulation lever 14 is provided on the lid member 11, and hence the lid member 11 can be opened and closed with a series of manipulations simultaneously with the manipulation of the manipulation lever 14, which leads to enhancement of manipulation properties.
  • the casing 4 including the base member 10 and the lid member 11 is not essential, and hence is not required to be provided. That is, functions as a printer can be sufficiently exerted only with the main unit 3 and the platen unit 2.
  • the rotary shaft portions 22b of the rocking members 22 are formed so as to project to the platen roller 21 side, this should not be construed restrictively.
  • the rotary shaft portions 22b may be formed so as to project to the outside opposite to the platen roller 21 side.
  • the latch member 23 is coupled to the rocking members 22 under a state of being positioned on the side opposite to the platen roller 21 side with the rocking members 22 being interposed therebetween, the similar actions and effects can be obtained also in this case.
  • the structure as described above in this embodiment is preferred.
  • lengths of the rocking members 22 or positions and sizes of the rotary shaft portions 22b may be set so that the coupling plates 31 of the latch member 23 are arranged between the platen roller 21 and the platen frame 20. With this, the lateral width of the printer 1 can be further reduced, and hence the printer 1 can be downsized.
