摘要:
A platen roller holding mechanism of a simple configuration allows an exchange and attachment of a platen roller and allows for printer miniaturization and light weight. This platen roller holding mechanism includes: a printer body; a thermal head disposed on the printer body, the thermal head configured to print on the sheet member; a platen roller disposed at a position opposite to the thermal head in a closed configuration, the platen roller pressing the sheet member to the thermal head. The platen roller holding mechanism rotatably secures the platen roller with respect to the device body. The platen roller holding mechanism includes a roll supporter that support the sheet member and a sheet member detector supporter that support a detector for detecting the sheet member. The roll supporter and the sheet member detector supporter are unitedly formed.

An elastic body roller which has an excellent non-stick property or release property, and frictional force (gripping force) and is able to stably feed and guide a belt-shaped member such as a linerless label, a typical liner label, or the like is provided. Attention has been paid to coating an outer layer of an inner layer elastic material member (23) having a silicone resin (a coating layer (24) with a C hardness (hardness by a spring-type Asker C type defined in the SRIS 0101 standard) set low. An elastic material member (22) of an elastic body roller has an inner layer elastic material member (23) provided on the outer periphery of a roller shaft ( 21) , and a coating layer (24) provided on the outer periphery of the inner layer elastic material member (23) and being in contact with a belt-shaped member, and the coating layer (24) is formed from a silicone resin with a C hardness of 20 degrees or less.

The invention relates to the thermal printing device with the so called "easy-loading" system for the paper. Thermal printing mechanism comprising: a printer chassis (2), a thermal printhead (1), platen roller (3) having a conductive shaft (6), the platen roller (3) being designed to be movable between two possible positions - open, where the platen roller (3) is detached from the printer chassis (2) and printing position where the platen roller (3) is held in the printer chassis (2), and motion means (11) to put the platen roller (3) in rotation. It further comprises two lateral conductive contacts (4 and 5) arranged on the printer chassis (2) so as to be in a contact with the two opposite ends of the platen roller conductive shaft (6) in the printing position of the platen roller (3) for conducting electrical current, thus forming an electrical switch for indication of the status of the platen roller position.

A liquid ejecting apparatus(11) includes a liquid ejecting head(15) ejecting liquid from nozzles(16) thereof formed on a nozzle formation surface(15a) onto a target(13) that is being transported; and a rotating member(18) rotatably disposed opposite the nozzle formation surface(15a), the rotating member(18) having a supporting surface(31) for supporting the target(13) and an absorbing surface(30) for absorbing the liquid ejected from the nozzle(16). The rotating member(18) has such a configuration that a first maximum length(B) from a rotational center(S) to the absorbing surface(30) is longer than a second maximum length(A) from the rotational center(S) to the supporting surface(31).

Disclosed is an inkjet recorder which ensures good print quality by minimizing flapping of a sheet which travels in parallel with the nozzle width region of an ink jet head while facing the nozzle width region. An inkjet recorder is equipped with an inkjet print section (4) having print units (7, 7') for printing on a sheet (2) traveling on an arcuate sheet passage formed of a plurality of guide rollers (12a-12h) by means of a plurality of inkjet heads (6a-6d, 6a'-6d'), wherein an on-demand inkjet head equipped with a plurality of nozzle arrays in the traveling direction of sheet as a nozzle width region is used as the inkjet head of the print unit, the sheet passage opposite to the nozzle surface of each inkjet head is constituted of two guide rollers (12a, 12b) disposed on the upstream side and downstream side in the traveling direction of sheet, and the end portions of a sheet in the nozzle width region (L) of each inkjet head on the upstream side and downstream side in the traveling direction of sheet are located as closely as possible to each contact point between the guide rollers on the upstream side and downstream side on the inside of each contact point where the sheet touches the guide rollers, respectively, and being wound therearound.

A thermal printer (40) includes a thermal head module (41), a platen module (42), and a gear module. The platen module (42) and the gear module are connected to the thermal head module (41). When setting a recording sheet (49) to the printer (40), the operator lifts up a knob (83, 64) provided to the platen module (42), so that the platen module is rotated counterclockwise around a pin (61d) provided to the thermal head module (41). In this manner, the platen separates from the thermal head, and setting a recording sheet becomes easier.

Provided is a platen roller retaining structure which is small, of a simple construction and easily allows attachment/detachment of a platen roller and which provides a high level of reliability in terms of platen roller retention. A shaft portion (2a) of a platen roller (2) is fitted into a connecting portion (3a) of a regulating member (3), and the shaft portion (2a) and an engagement portion (3b) of the regulating member (3) are respectively inserted into a first recess (5) and a second recess (6) of a stationary frame (4), with an outer peripheral portion (2b) of the platen roller (2) being held in contact with a thermal head (1) to make recording possible. Escape of the shaft portion (2a) from the first recess (5) in direction (A) is prevented by an inner peripheral edge (5a) . Escape of the shaft portion (2a) toward an opening portion (5b) in direction (B) without being obstructed by the inner peripheral edge (5a) is prevented since the engagement portion (3b) abuts an inner peripheral edge (6a) and cannot move in direction (B). Removal of the platen roller (2) is possible only when the engagement portion (3b) has been caused to escape in direction (C) from the second recess (6), with the shaft portion (2a) being kept retained within the first recess (5).
