押圧伏態にあり、印刷紙7に印刷を行なう。Further, the feed screw shaft 5 is fitted into the frame 8, and the guide rod 6 is loosely fitted into the elongated hole 8-1 of the frame 8, freely rotating around the feed screw shaft 5, and is applied with force in the direction of arrow F by the elastic member 4. In response to this, the printer head 1 is pressed down against the platen 2 via the printing paper γ, and prints on the printing paper 7.

ド1が押圧状態にあるために、押圧力がプリンタの待機
(停止)状態での印刷紙7の挿入性を大きく妨げ、さら
に紙づまりの原因となる欠点を有していた。Here, in this type of mechanism, the platen 2 and the printer head 1 are always in a pressed state, so the pressing force greatly impedes the insertion of the printing paper 7 when the printer is in a standby (stopped) state, and can also cause paper jams. It had some drawbacks.

ドの間に間隙を作り、待機(停止)状態における印刷紙
挿入時の負荷の軽減と紙づまりをなくすことにある。An object of the present invention is to create a gap between the platen supporting printing paper and the printer head by providing a convex portion on the platen at the position of the printer head in the standby (stopped) state of the printer. The purpose is to reduce the load when inserting printing paper in the (stopped) state and eliminate paper jams.

時間を短縮することにある。Another object of the present invention is to reduce the time it takes for the printer head to return to the standby position by consuming the inertial energy immediately before the printer head enters the standby state on a cam surface provided on the platen.
本発明に於けるプリンタの印字機構を第2図に示す。FIG. 2 shows the printing mechanism of the printer according to the present invention.
プラテン2の印刷紙7と対向しない部分に凸部2−1と
斜面カム2−2を設ける。A convex portion 2-1 and an inclined cam 2-2 are provided in a portion of the platen 2 that does not face the printing paper 7.

, B Printing is performed on the printing paper 7 held between the platen 2 and the printer head 1 during reciprocating sliding in both directions, and the printable range is the reciprocating sliding range C' of the printer head printing section 1-1. be.
(c=c’)次に通常印刷動作から待機(停止)状態へ
移る動作を第3図、第4図にて説明する。(c=c') Next, the operation of shifting from the normal printing operation to the standby (stop) state will be explained with reference to FIGS. 3 and 4.
第3図に於いてプリンタヘッド保持体3が矢印A方向へ
摺動した後に待機(停止)状態となるとする。In FIG. 3, it is assumed that the printer head holder 3 slides in the direction of arrow A and then enters a standby (stopped) state.

となる。Figure 4 shows a cross-sectional view of the printing mechanism of the printer in the standby (stopped) state. In order to ensure the sliding range C', one drive of the reciprocating sliding is cut off after sliding the reciprocating sliding range C, so even if a means such as a stop control circuit is used for the motor of the drive source, D due to inertial energy. >C

性エネルギを消費することにより駆動源に停止距離制御
を特に用いなくても通常動作状態から待機(停止)状態
に移る停止時間を短かくできる。Therefore, by actively using inertial energy to move the printer head 1 or the printer head holder 3 onto the convex portion 2-1 via the inclined cam 2-2, the printer head 1 and the printing paper 7 are faced to each other. The printer head 1, which was in contact with the printing paper 7 in a pressed state, is separated from the printing paper 7 by widening the gap E between the printing paper 7 and the platen 2, thereby improving the ease of inserting the printing paper 7 in the standby (stopped) state. In addition, by consuming inertial energy, the stopping time for transitioning from the normal operating state to the standby (stopped) state can be shortened without using stopping distance control for the drive source.
さらにこの停止時間はプラテン2の凸部2−1の高さ及
び斜面カム2−2の形状及び摺動部の摩擦係数により調
整が可能である。Furthermore, this stopping time can be adjusted by the height of the convex portion 2-1 of the platen 2, the shape of the inclined cam 2-2, and the friction coefficient of the sliding portion.

できる。The above is an example of the present invention, and the reciprocating movement of the print head is performed once.
It is not limited to the feed screw shaft 5 which is driven by forward and reverse rotation of the drive device, but also the helical grooves 9 that intersect as shown in FIG.
Even if the drive means always has the same reciprocating sliding range by using the feed screw shaft 9 which has a unidirectional rotation and reciprocatingly slides, the convex portion 2-1 of the platen 2 can be made longer. By widening the gap E between the platen 2 and the printer head 1 during paper feeding, this can be used to reduce the paper feeding load.

、きわめて簡単な構或である等の利点を有する。As explained above, the present invention is designed to release the pressing force between the printer head and the platen that holds the printing paper while the printer is in the standby (stopped) state by the reciprocating sliding movement of the printer head unit. This has the advantages of improving the ease of inserting printing paper, shortening the time the printer is stopped from operating, and having an extremely simple structure.
