Embodiment Construction

[0028] figure 1 It is a perspective view showing the appearance of a dot matrix printer as a recording device to which an embodiment of the present invention is applied. The dot matrix printer of this embodiment is provided with a recording head 18 (refer to figure 2 and image 3 ), the recording head 18 is equipped with a plurality of recording metal wires, and the recording metal wires are molded toward the recording medium through the ink ribbon from the recording head 18, thereby forming dots on the recording surface of the recording medium, and recording (printing) characters or symbols, images Wait.

[0029] An image recorded by the dot matrix printer 10 consists of one or more lines, and is recorded on a line-by-line basis. Here, when recording is instructed to the dot matrix printer 10 from an external device (host computer, etc.), the instruction can be performed in units of lines or units of pages.

Abstract

The invention provides a platen which can reduce noise caused by passing through a platen of a recorder formed by resin. The platen comprises: a platen base (61) which extends in a moving direction of a carriage and is made of resin; and a platen surface which is pressed by a guiding roller disposed on the carriage and bears an impact force of a recording head loaded on the carriage. The platen base (61) is elastically supported by elastic supporting holes (72, 72) disposed at both sides in the longitudinal direction. A reinforcing plate (63) is integrally disposed within a range including the part between elastic supporting shafts (69, 69). A low-rigidity part (73) with lower rigidity than that of other parts is disposed between the elastic supporting holes (72, 72) on the platen base (61).

Description

technical field [0001] The present invention relates to a platen and a recording device provided with the platen. Background technique [0002] Conventionally, it is known to record on a recording medium by causing a plurality of wires or the like included in the recording head to punch the recording medium conveyed between the recording head mounted on the carriage and a flat platen platen. recording device (for example, refer to Patent Document 1). Patent Document 1 discloses a structure in which a steel plate is bent to form an embossed flat plate that receives impact force from a metal wire. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2004-330621 [0004] As described in Patent Document 1, when a metal platen is used, it is difficult to form the platen into a complicated shape. Therefore, when the shape of the platen becomes complicated, for example, to provide protrusions for guiding the recording medium, resin molding of the platen may be considered. ...
