Abstract

PURPOSE:To prevent paper from coming up from a printing surface during printing, by a method wherein a movable card holder is moved in a direction of pressing the paper down when a printing head impacts. CONSTITUTION:A card holder 3 can be moved in a platen 6 direction by driving a solenoid 6. A spring 7, when the solenoid 6 is not driven, moves the card holder 3 onto a printing head 4 side. By moving the card holder, noise to be generated by coming up of paper from the platen or an anvil can be prevented during printing. Since an interval between the platen or the anvil and the card holder can be taken enough when printing is not performed, sucking of paper and clogging of paper at the time of line feed can be prevented.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明はドツトインパクトシリアルプリンタに関し、特
に印字中における用紙の印字面からの浮きあがり防止機
構に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dot impact serial printer, and more particularly to a mechanism for preventing paper from lifting off the printing surface during printing.

〔従来の技術〕[Conventional technology]

従来、ドツトインパクトシリアルプリンタにおいては、

The card holder was fixed to the print head.

欠点があった。Since the conventional card holder described above has a structure that is fixed to the print head, the distance between the paper and the card holder is fixed unless the print head is moved. In addition, in order to ensure the distance between the card holder and the paper so that no excessive load is applied to the paper during paper suction or line feeding, a gap is created between the paper and the platen or anvil when the print head impacts. The drawback was that the gap caused noise when the print head impacted.

の紙づまりを防ぐことができるという効果がある。As explained above, the present invention prevents the noise caused by paper lifting from the platen or anvil during printing by moving the card holder, and maintains a sufficient distance between the platen or anvil and the card holder when not printing. This has the effect of preventing paper inhalation and paper jams during line feeding.
