、２はギヤー、３はピニオンで、図示しない駆動装置に
よりピニオン３が駆動され、ギヤー２の回動により保持
筒１は回転可能に構成されている。Figure 1 shows an example of the configuration of a conventional pencil head used in a pencil drawing device. In Figure 1, 1 is a holding cylinder, 2 is a gear, and 3 is a pinion. The pinion 3 is driven by a drive device (not shown) The holding cylinder 1 is configured to be rotatable by rotation of the gear 2.
４は軸受である。５は鉛筆芯を保持する弾性部材（図示
せず）を内蔵するペンシルガイドで、保持筒１に複数個
設けられている。4 is a bearing. A plurality of pencil guides 5 are provided in the holding tube 1, and include elastic members (not shown) for holding pencil leads.
描画の際のペンシルガイドの上下動は上昇させるための
バネ６と下降するための下降装置（ソレノイド１、アー
ム８、ピン９、バネ１０）とにより上下動するように構
成されている。The pencil guide is configured to move up and down during drawing by a spring 6 for raising it and a lowering device (solenoid 1, arm 8, pin 9, spring 10) for lowering it.
保持筒１の締結は、保持筒１の上部の連結具１１にピン
１２の挿入穴１２ａを設け、さらに前記挿入穴１２ａに
直交してコツタ１３の挿入穴１３ａを設け、コツタ１３
はブラケット１４に埋設されたメタル１５等で摺動可能
に構成され、バネ１６によってコツタ１３は前進し連結
具１１が上方に引張られ保持筒１は固定される。To fasten the holding cylinder 1, an insertion hole 12a for the pin 12 is provided in the connecting tool 11 at the upper part of the holding cylinder 1, and an insertion hole 13a for the cotter 13 is provided perpendicularly to the insertion hole 12a.
is configured to be slidable by a metal 15 etc. embedded in a bracket 14, and a spring 16 moves the lever 13 forward, pulls the connector 11 upward, and fixes the holding cylinder 1.
保持筒１の装置からの脱着は、保持筒１を上方に引き上
げてコツタ１３を引くことにより可能となる。The holding cylinder 1 can be attached and detached from the device by pulling the holding cylinder 1 upward and pulling the handle 13.
１８は鉛筆芯の筆圧発生の媒体として用いられる芯押し
棒で、上端部はブラケット１９に設けられたクランプ２
０，２１、バネ２２により支えられている。Reference numeral 18 is a lead pusher rod used as a medium for generating pressure on the pencil lead, and the upper end is a clamp 2 provided on the bracket 19.
0, 21, supported by springs 22.
２３は芯押し棒１８と並夕Ｉルて設置されるラックで、
上端部はブラケット１９に結合されている。23 is a rack installed in parallel with the tailstock 18,
The upper end is connected to a bracket 19.
２４はガイド、２５はメタルである。２６はピニオンで
ラック２３に噛合している。24 is a guide, and 25 is a metal. A pinion 26 meshes with the rack 23.
２γはピニオン２６と結合している検出器付モータであ

この検出器付モータ２γを駆動することにより、ラック
２３を下降させ芯押し棒１８に筆圧を与える。By driving this detector-equipped motor 2γ, the rack 23 is lowered and writing pressure is applied to the core push rod 18.
かかる構成のペンシルヘッドは、ペンシルガイドが上下
動する機構なので、ペンシルガイド５の最外形が大きく
なり、さらには保持筒１の外形も大きくなり、重量も重
くなる。Since the pencil head with such a configuration has a mechanism in which the pencil guide moves up and down, the outermost shape of the pencil guide 5 becomes large, and furthermore, the outer diameter of the holding cylinder 1 also becomes large and the weight becomes heavy.
またペン上下動にソレノイドγと筆圧用の検出器付モー
タ２１でタイミング動作してるためペンシル上下動作が
遅く、描画速度を早めることができない。Furthermore, since the vertical movement of the pen is controlled by the solenoid γ and the motor 21 with a pressure sensor, the vertical movement of the pencil is slow and the drawing speed cannot be increased.
また保持筒１の脱着がわずられしく、構造が複雑であり
、保持筒１と描画面１１との間隔も変化しやすく描画ズ
レが生ずる。Further, it is difficult to attach and detach the holding cylinder 1, the structure is complicated, and the distance between the holding cylinder 1 and the drawing surface 11 is likely to change, causing a drawing deviation.
描画時における鉛筆芯の折損を生じ、残芯が長い等の欠
点があった。There were drawbacks such as the pencil lead breaking during drawing and the remaining lead being long.
本発明は上述したような点に鑑みなされたもので、以下
本発明を実施例図面にもとづいて説明する。The present invention has been made in view of the above-mentioned points, and the present invention will be explained below based on the drawings of the embodiments.
