本発明は自動開閉防塵カバー付サーマルプリンタに関し
、特に塵埃に対して耐性の低いサーマルプリンタを対象
とした自動開閉防塵カバー付サーマルプリンタに関する
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a thermal printer with an automatically opening/closing dustproof cover, and more particularly to a thermal printer with an automatically opening/closing dustproof cover intended for a thermal printer with low resistance to dust.
従来、この種のプリンタは、塵埃に弱いプリンタヘッド
を守るため、塵埃がヘッドに積りにくい構造、風向きに
することにより対処していた。Conventionally, in order to protect the printer head, which is susceptible to dust, printers of this type have had a structure and a wind direction that makes it difficult for dust to accumulate on the head.
上述した従来のサーマルプリンタの塵埃対策では、プリ
ンタヘッドを完全に外部から隔離することは不可能であ
り、塵埃対策としては不十分であるという欠点がある。The conventional dust countermeasures for thermal printers described above have the drawback that it is impossible to completely isolate the printer head from the outside, and the dust countermeasures are insufficient.
本発明の自動開閉防塵カバー付サーマルプリンタは、使
用状況に応じて自動的に開閉する防塵カバーを有する。The thermal printer with an automatically opening/closing dustproof cover of the present invention has a dustproof cover that automatically opens and closes depending on usage conditions.
また、本発明の自動開閉防塵カバー付サーマルプリンタ
は、前記防塵カバーを閉じるタイミングを、プリンタ用
紙の切断状態を検出したタイミングとして動作する構成
を有する。Further, the thermal printer with an automatically opening/closing dustproof cover of the present invention has a configuration in which the timing for closing the dustproof cover is set to the timing when the cutting state of printer paper is detected.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.
第１図は本発明の一実施例の縦断面図である。FIG. 1 is a longitudinal sectional view of an embodiment of the present invention.

示す。The embodiment shown in FIG. 1 includes a horizontally movable shield cover 1 that slides in the sliding direction a (not shown by an arrow) to open to the operational state and closes by sliding in the sliding direction 5, and a drive motor. A built-in shield cover opening/closing mechanism 2 that opens and closes the cover 1 by sliding it in the horizontal direction, a printer head 3 for printing, and a paper 8σ for printing on the printer 1)
It comprises a pair of paper sensors 1 facing each other as optical sensors for detecting the presence or absence, a CPU 5, a cutter 6 for cutting the printer I/paper, and a case 7 for storing these parts, as shown in FIG. Pudding 1 to paper 6 are also shown here.
次に、第１図の実施例の動作について説明する。Next, the operation of the embodiment shown in FIG. 1 will be explained.
プリン１〜用紙８は、プリンタヘッド３によって印刷さ
