In conventional printing devices, the top surface of the platen is open so that the printing head moves in the row direction and prints at that section. If the paper sheet is inserted curled or bent,
There was a problem that the paper would fly out of the opening and cause a paper jam.

特開昭56−34483号公報に掲載されている。 As another example, a method has been proposed in which a shutter member made of a flat plate is provided at the opening of the platen, but this method cannot be made small and is complicated and expensive as it requires a drive source to open and close the flat shutter member. There was a problem. Incidentally, the typical printing device is, for example,
It is published in Japanese Patent Application Laid-open No. 56-34483.
本発明はこうした従来装置における問題点に鑑
み、構造が簡単で安価で、且つ用紙ジヤムの発生

SUMMARY OF THE INVENTION In view of these problems with conventional devices, the present invention provides a printing device that is simple in structure, inexpensive, and does not cause paper jams.
本発明の主たる目的は前述の通り、プラテン開
口部における用紙ジヤムの防止を構造簡単で安価
な機構で完致しようとするものである。 As mentioned above, the main object of the present invention is to completely prevent paper jams at the platen opening using a simple and inexpensive mechanism.
さらに他の目的は、該ジヤム防止機構は小型で
且つ駆動源を必要としない高い信頼度の印字装置
を提供しようとするものである。 Still another object is to provide a highly reliable printing device in which the jam prevention mechanism is compact and does not require a driving source.

る。 Furthermore, by making the guide member press-operable by the row direction movement of the carrier, there is no need for a drive source for the guide member, and when guiding the paper to the platen portion, the carrier can be placed in a position where the pressure is released. This closes the platen opening and allows paper to be guided without jamming.
以下に本発明の一実施例を第１図〜第４図によ

３，１４を設けている。 Paper 4 is conveyed by rollers 5, guided by guides 6 and 7, sent to platen 8, guided by guides 9 and 10, and sent to rollers 11. However, the top of the platen 8 is open, and as it is, the leading edge 4 of the paper 4
A is not guided by the guides 9 and 10 and flies upward, causing a paper jam. Therefore, in the present invention, a plurality of shutters 12 and 1 are provided so that the leading edge 4a of the paper is safely guided by the guides 9 and 10.
3 and 14 are provided.

トツパ２３により係止されている。 The shutters 12, 13, 14 are rotatably removed around pivots 15, 16, 17 provided on the guide 7, and are attached to pins 19, 19 by links 18.
20 and 21 are connected. Shutter 12,
13 and 14 are urged by a spring 22 to be positioned at the illustrated position when the paper is sucked in, and are locked by a stopper 23.
用紙４が吸入されると、第３図に示す如く、キ

上に行方向に逐次印字するようになつている。 When the paper 4 is sucked in, the carrier 2 is moved in the direction of arrow A, as shown in FIG.
It is designed to print sequentially in the row direction at the top.

Continue printing. The shutters 12, 13, 14 are
As described above, they are integrally connected by the link 18, and if any one shutter is pressed against the ski 24, the upper part of the platen is held open as shown.

るという効果がある。 Therefore, even when the carrier 2 returns in the opposite direction of the arrow A, the operation is not hindered. When the carrier 2 returns to its home position (as shown in Figure 1), the shutter returns to its original position and closes the opening on the platen sufficiently to guide the paper the next time it is to be sucked in. [Effects of the Invention] As is clear from the above explanation, the shutter mechanism according to the present invention has an extremely simple structure and can store paper in a small space at the platen opening, which has been difficult in the past. This has the effect of making it possible to provide a stable printing device in which paper jams do not occur in the relevant section.
さらに本発明によれば、シヤツタの開閉に特別

みならず、安価にできるなどの副次的利点も大き
い。 Further, according to the present invention, a special driving source is not required for opening and closing the shutter, and not only can power consumption be reduced, but there are also great secondary advantages such as low cost.
