に嵌合されることにより装着される。 A conventional type wheel has a structure as shown in FIGS. 1, 2, and 3. That is, the type wheel, generally designated by the reference numeral 1 in FIG. 1, is assembled on the basis of a cylindrical base 2 as shown in FIG. Through holes 2a and 2b are formed on the circumferential surface of the base 2 in a staggered manner along the axial direction at regular intervals. A staggered type belt 3 as shown in FIG. 3 is attached to the base 2. The type belt 3 is made of an elastic material such as nitrile rubber, urethane rubber,
It is made of silicone rubber, fluoroprene rubber, natural rubber, styrene-butadiene rubber, chlorosulfonated polyethylene, butyl rubber, ethylene propylene rubber, fluorocarbon rubber, neoprene rubber, acrylic rubber, epichlorohydrin rubber, etc. Type parts 3a are provided protrudingly on a type stand 3b, and protrusions 3c are provided on the back surface of the type belt 3, facing the type stand 3b. When the type belt 3 is attached to the base 2, the protrusion 3c on the back side thereof is fitted into the through hole 2a.

により接続され環状に形成される。 More specifically, the third through hole 2a in row K in FIG.
The projections 3c in the M row in the figure are fitted, and the L in FIG.
N rows of protrusions 3c in FIG. 3 are fitted into the rows of through holes 2b. Also, the ends of the type belt 3 are connected by a suitable method to form a ring.
活字輪１には回転自在な軸を中心に常時圧接し
て活字輪にインクを供給する不図示のインクロー
ラが接触する。 An ink roller (not shown) that constantly presses around a rotatable shaft to supply ink to the type wheel 1 is in contact with the type wheel 1 .

ンジヤが配置されており、その可動鉄心の先端部
は印字ハンマー４となつている。 Further, a plunger (not shown) is arranged inside the type wheel 1, and the tip of the movable iron core serves as a printing hammer 4.
又、活字輪１と対向してプラテン５が配置され
ている。 Further, a platen 5 is arranged opposite to the type wheel 1.
以上のような構成において、図示されていない
制御装置によつて活字輪１が回転し、文字ないし
記号を選択し、突起部３ｃとハンマー４が正対し
たときに活字輪１は停止し、ハンマー４が左方に
突出し、プラテン５を介して印字紙６に選択され
た文字ないし、記号を印字する。 In the above configuration, the type wheel 1 is rotated by a control device (not shown) to select a character or symbol, and when the protrusion 3c and the hammer 4 directly face each other, the type wheel 1 is stopped and the hammer is rotated. 4 protrudes to the left and prints selected characters or symbols on printing paper 6 via platen 5.
又印字効率を向上させるために前述の弾性を有
する材料、しかも硬度がA30゜〜50゜の如く柔かい
ゴム質を有する材料が選定される。 Further, in order to improve printing efficiency, a material having elasticity as described above and a soft rubbery material having a hardness of A30° to 50° is selected.

しまう。 However, when the above-mentioned type wheel is adopted, certain characters and symbols on the type wheel, such as the negative sign (-) in Figure 3, 3a, and the decimal point symbol (.)
Characters with a small surface area of the type, such as type 3d,
When the symbol is projected by the hammer 4 and pressed against the platen 5, the type plate shoulder 3b' also comes into contact with the printing paper 6, which has the drawback of easily causing so-called printing smear. Such print stains impair the print quality and, in turn, reduce the commercial value of the printer.
又、これらの汚れをさけるため硬度の高いゴム
質を選定すればよいが、こうすると、活字部面積

印字力が不足になり印字がかすれる現象が生じ
る。 Also, in order to avoid these stains, a rubber material with high hardness should be selected, but if you do this, characters with a large type area - for example, characters such as "0" and "8"
Printing power is insufficient and the printing becomes blurred.
本発明の目的は、上記問題点を解消して、印字
品位を向上させることのできる活字輪を提供する
ことにある。 An object of the present invention is to provide a type wheel that can solve the above problems and improve printing quality.
以下図面に示す実施例に基づいて本発明を詳細
に説明する。 The present invention will be described in detail below based on embodiments shown in the drawings.

活字台３ｂの高さより低くなつている。 4 and 5 illustrate an embodiment of the present invention, and the height of the type stand 3b' of the type 3a of the type belt 3 is the height of the type 3a of the type belt 3 shown in FIGS. 1 and 2. It is lower than the height of the stand 3b.
このように、活字台高さを低くすることによ
り、活字部表面面積の小さい文字・記号は活字台
肩部３bb′が印字用紙６に接触せず、いわゆる印
字汚れを起こさず、良好な印字品位が得られる。 In this way, by reducing the height of the type stand, when printing characters and symbols with a small surface area, the type stand shoulders 3bb' do not come into contact with the printing paper 6, and so-called print smudges do not occur, resulting in good print quality. is obtained.
又、同様な措置を“１”“７”等の数字“Ｔ”
“√”“Ｐ”等の記号に施しても同様な効果を期待
できる。 In addition, similar measures will be taken with numbers “T” such as “1” and “7”.
A similar effect can be expected by applying it to symbols such as "√" and "P".
以上説明した通り、本発明によれば印字品位を
