ターに対する鉛筆の振動が大きいため芯が折れやすく、
小径鉛筆への使用に対しては不適であった。
Conventionally, electric pencil devices have had a pencil insertion slot on the top of the cutter operating chamber that fits a general-sized 8φ pencil, but no structure has been provided to accommodate small-diameter pencils such as notebook pencils. If you insert a small-diameter pencil into the pencil insertion slot 8 as is, the diameter of the insertion slot is too large, and the switch that detects the insertion state of the pencil and drives the cutter may not move to the ON position, or the switch may not move to the ON position. Even if the cutter is turned on and the cutter is activated, the lead may easily break due to the large vibration of the pencil relative to the cutter.
It was unsuitable for use with small diameter pencils.

そこで本考案はカッター作動室20上面に設けられた鉛
筆挿入口8の上部を進退自在に移動し、かつ上記鉛筆挿
入口8より小径の鉛筆挿入口3を穿設したアダプタ−1
