The shutter member main body 17a is configured to retract toward the base side of the upper blade 16 against an urging force in the direction of the blade edge 16a by an elastic member (not shown).

次に、図１ないし図４を参照して、切断装置４の使用状態を説明する。
印字媒体７を装着するために開閉カバー部１４を、ヒンジ６を回動支点として開放方向（矢示Ｐ方向）に引き上げると、開閉カバー部１４に取り付けられている上刃１６が下刃１５より離反し分離される。開閉カバー部１４の閉成時（図２および図４参照）には、係合部１７ｂと第１の支持フレーム１８の段差部２０との係合により上刃１６の根元側にシャッター部材１７が後退して刃先１６ａを露出していたが（図４参照）、開閉カバー部１４の引き上げにより弾性部材（図示省略）の付勢力でシャッター部材１７は刃先１６ａ側に進出して上刃１６の前面を覆う（図３参照）。これにより、開閉カバー部１４が開放されたとしても、シャッター部材本体部１７ａが刃先１６ａを覆うため、上刃１６により怪我をすることがないものである。
媒体供給部２に印字媒体７を装着し、下刃１５の上方に引き出し、次いで、開閉カバー部１４を閉じる。開閉カバー部１４を閉鎖時、シャッター部材１７は上刃１６の刃先１６ａの前面を覆ったままの状態で下刃１５側へ回動され、シャッター部材１７の係合部１７ｂが第１の支持フレーム１８の段差部２０に当接して位置決めされるとともに、さらに、閉鎖方向に開閉カバー部１４を閉じると、弾性部材（図示省略）の付勢力により上刃１６を覆っていたシャッター部材１７は、付勢力に抗して上方に押し上げられ、刃先１６ａを印字媒体７に向けて露出し、下刃１５に対向した位置に上刃１６を位置決するものである。 Next, the use state of the cutting device 4 will be described with reference to FIGS.
When the opening / closing cover part 14 is pulled up in the opening direction (arrow P direction) with the hinge 6 as a rotation fulcrum in order to mount the printing medium 7, the upper blade 16 attached to the opening / closing cover part 14 comes from the lower blade 15. Separated and separated. When the open / close cover portion 14 is closed (see FIGS. 2 and 4), the shutter member 17 is located on the base side of the upper blade 16 due to the engagement between the engaging portion 17b and the stepped portion 20 of the first support frame 18. The blade edge 16a is exposed by retreating (see FIG. 4), but the shutter member 17 advances to the blade edge 16a side by the urging force of the elastic member (not shown) by pulling up the opening / closing cover portion 14, and the front surface of the upper blade 16 (See FIG. 3). Thereby, even if the opening / closing cover part 14 is opened, the shutter member main body part 17a covers the blade edge 16a, so that the upper blade 16 is not injured.
The print medium 7 is mounted on the medium supply unit 2, pulled out above the lower blade 15, and then the opening / closing cover unit 14 is closed. When the open / close cover portion 14 is closed, the shutter member 17 is rotated toward the lower blade 15 while covering the front surface of the blade edge 16a of the upper blade 16, and the engaging portion 17b of the shutter member 17 is the first support frame. When the opening / closing cover part 14 is closed in the closing direction, the shutter member 17 covering the upper blade 16 by the urging force of an elastic member (not shown) is attached. The blade 16a is pushed upward against the force, the blade edge 16a is exposed toward the print medium 7, and the upper blade 16 is positioned at a position facing the lower blade 15.

次に、図５および図６を用いて、本発明の切断装置の他の実施の形態につき説明する。
なお、以下において、先の実施の形態と同様の部分は同一符号を付すに止め、詳説を省略する。
図５は、開閉カバー部１４の開放時の下刃１５および下刃１６の状態を示す側面図、図６は、開閉カバー部１４の閉成時の下刃１５および下刃１６の状態を示す側面図である。
切断装置３０は、主に、下刃１５と、上刃１６と、シャッター部材３１とを備えており、下刃１８は、プリンタ本体５側に固定された第１の支持フレーム１８を介し、上部側に刃先１５ａを向けた状態で進退動自在に設けられている。また、第１の支持フレーム１８の適宜位置には、後述するシャッター部材３１の「開放用の係合部」としての係合ピン３３が形成されている。
上刃１６は、刃先１６ａを前記下刃１５側に向け第２の支持フレーム１９を介して開閉カバー部１４側に固定されており、ヒンジ６を回動支点として開閉カバー部１４を開放方向（矢示Ｐ方向）に引き上げると、開閉カバー部１４に連動して上刃１６は下刃１５から離反し分離されて開放される。
シャッター部材３１は、上刃１６の前面を覆うシャッター部材本体部３１ａと、このシャッター部材本体部３１ａより裏面側（図５および図６における右側）に突出して幅方向の左右に形成された一対のアーム部３１ｂとを備えており、アーム部３１ｂの係合孔３２は、開閉カバー部材１４に設けられた図示省略の係合軸に回動自在に軸支されている。
上記構成の切断装置３０は、ヒンジ６を回動支点として開閉カバー部１４を開放方向（矢示Ｐ方向）に引き上げるのに伴い、開閉カバー部１４の係合軸（図示省略）に係合孔３２を介して取り付けられたシャッター部材３１が自重で上刃１６側に回動され、上刃１６に接触して刃先１６ａの前面をシャッター部材本体部３１ａにて覆う。したがって、開閉カバー部１４を開放しての印字媒体７の装着作業時、シャッター部材３１が刃先１６ａを覆っていることにより、怪我をすることがないものである(図５参照)。
次いで、開閉カバー部１４を閉じる。開閉カバー部１４の閉鎖時、上刃１６および上刃１６の前面を覆っているシャッター部材３１は共に下刃１５側へ回動されるが、プリンタ本体５の適宜位置に設けられた前記開閉用の係合ピン３３にアーム部３１ｂが当接することにより、係合孔３２を回動基点として上刃１６よりシャッター部材３１が離反する方向に回動して刃先１６ａを露出し、印字媒体７の搬送および切断に邪魔とならない位置に回動して位置決めされる（図６参照）。
開閉カバー部１４の回動に連動して回動する上刃１６およびシャッター部材３１の回動軌跡の適宜位置に設けた係合ピン３３に、シャッター部材３１のアーム部３１ｂが当接することによりシャッター部材３１を上刃１６の刃先１６ａより離反方向に回動するので、弾性部材(図示省略)を設けて刃先１６ａと根元の間においてシャッター部材１７を進退動自在とした先の実施例に比べ、簡単な構成で刃先１６ａの被覆および露出ができるものである。
その他の構成、作用、効果については、先の実施の形態とほぼ同様につき詳説を省略する。 Next, another embodiment of the cutting device of the present invention will be described with reference to FIGS. 5 and 6.
In the following description, the same parts as those in the previous embodiment are designated by the same reference numerals, and detailed description thereof is omitted.
FIG. 5 is a side view showing the state of the lower blade 15 and the lower blade 16 when the opening / closing cover portion 14 is opened, and FIG. 6 shows the state of the lower blade 15 and the lower blade 16 when the opening / closing cover portion 14 is closed. It is a side view.
The cutting device 30 mainly includes a lower blade 15, an upper blade 16, and a shutter member 31, and the lower blade 18 is connected to an upper portion via a first support frame 18 fixed to the printer body 5 side. It is provided so as to be movable back and forth with the blade edge 15a facing the side. In addition, an engagement pin 33 as an “engagement part for opening” of a shutter member 31 described later is formed at an appropriate position of the first support frame 18.
The upper blade 16 is fixed to the opening / closing cover portion 14 side via the second support frame 19 with the cutting edge 16a facing the lower blade 15 side, and the opening / closing cover portion 14 is opened in the opening direction with the hinge 6 as a pivot (fulcrum). When pulled up in the direction of the arrow P), the upper blade 16 is separated from the lower blade 15 in conjunction with the opening / closing cover portion 14 and is released.
The shutter member 31 includes a shutter member main body 31a covering the front surface of the upper blade 16, and a pair of left and right formed in the width direction so as to protrude from the shutter member main body 31a to the back side (right side in FIGS. 5 and 6). The engagement hole 32 of the arm portion 31b is pivotally supported by an engagement shaft (not shown) provided in the opening / closing cover member 14 so as to be rotatable.
The cutting device 30 configured as described above has an engagement hole formed in the engagement shaft (not shown) of the opening / closing cover portion 14 as the opening / closing cover portion 14 is pulled up in the opening direction (arrow P direction) using the hinge 6 as a pivot. The shutter member 31 attached via 32 is rotated to the upper blade 16 side by its own weight, contacts the upper blade 16, and covers the front surface of the blade edge 16a with the shutter member main body 31a. Therefore, when the print medium 7 is mounted with the opening / closing cover 14 opened, the shutter member 31 covers the blade edge 16a, so that there is no injury (see FIG. 5).
Next, the open / close cover portion 14 is closed. When the opening / closing cover portion 14 is closed, the upper blade 16 and the shutter member 31 covering the front surface of the upper blade 16 are both turned to the lower blade 15 side. When the arm portion 31b comes into contact with the engagement pin 33, the blade member 16a is exposed by rotating the shutter member 31 away from the upper blade 16 with the engagement hole 32 as a rotation base point. It is rotated and positioned to a position that does not interfere with conveyance and cutting (see FIG. 6).
When the upper blade 16 that rotates in conjunction with the rotation of the opening / closing cover portion 14 and the engagement pin 33 provided at an appropriate position on the rotation locus of the shutter member 31, the arm portion 31b of the shutter member 31 comes into contact with the engagement pin 33. Since the member 31 is rotated in the direction away from the blade edge 16a of the upper blade 16, compared to the previous embodiment in which an elastic member (not shown) is provided and the shutter member 17 is movable forward and backward between the blade edge 16a and the root. The blade edge 16a can be covered and exposed with a simple configuration.
About another structure, an effect | action, and an effect, detailed description is abbreviate | omitted since it is the same as that of previous embodiment.

なお、上記実施の形態の構成及び動作は例であって、本発明の趣旨を逸脱しない範囲で適宜変更することができることは言うまでもない。   It should be noted that the configuration and operation of the above-described embodiment are examples, and it goes without saying that they can be changed as appropriate without departing from the spirit of the present invention.

例えば、説明の都合上、上刃１６を「固定刃」とした例で説明したがこれに限定されないことは勿論であり、上刃を「可動刃」としてこれをシャッター部材で覆うようにしても構わない。
