【考案の詳細な説明】
(イ) 産業上の利用分野
本考案は、フアクシミリ等の記録装置の紙詰り
検出装置に関する。[Detailed description of the invention] (a) Industrial application field The present invention relates to a paper jam detection device for a recording device such as a facsimile machine.
(ロ) 従来技術
一般にフアクシミリ等の記録装置に於いては、
記録紙の紙詰りを検出する方法として、従来第１
図に示すような検出方法が行なわれていた。即

５の隙間を通つて排出されるよう構成されてお
り、紙詰りの発生で記録紙１が破線で示すように
繰り出された場合、反射型センサ６により、記録
紙１の繰り出しを検出し、装置の動作を停止させ
ると共に警報を発生するよう構成されている。(b) Prior art In general, in recording devices such as facsimile machines,
Conventionally, the first method for detecting paper jams was
The detection method shown in the figure was used. That is, the roll-shaped recording paper 1 is rotated by the platen roller 3 pressed against the recording head 2, and the guide plate 4,
If a paper jam occurs and the recording paper 1 is fed out as shown by the broken line, the reflective sensor 6 detects the feeding of the recording paper 1, and the device The system is configured to stop the operation of the system and generate an alarm.
ところが、反射型センサ６は放射光線に対し
て、繰り出された記録紙１が直角に対向した時確
実に検出するよう構成されている為、第１図に破
線で示すように記録紙１が傾いて繰り出された場
合、反射型センサ６の検出性能のバラツキ等によ
り、紙詰りを検出できない場合があり問題となつ
ていた。 However, since the reflective sensor 6 is configured to reliably detect when the recording paper 1 that has been fed out faces the radiation beam at right angles, the recording paper 1 may be tilted as shown by the broken line in FIG. When the paper is fed out, there is a problem in that it may not be possible to detect a paper jam due to variations in the detection performance of the reflective sensor 6.
(ハ) 考案の目的
本考案は、上述の問題点を解消することを目的
とするものである。(c) Purpose of the invention The purpose of the invention is to solve the above-mentioned problems.
(ニ) 考案の構成
本考案は、紙詰りの発生で繰り出された記録紙
が、反射型センサに対し直角に対向するようガイ
ド板を改良したものである。(d) Structure of the invention In the invention, the guide plate is improved so that the recording paper that is fed out when a paper jam occurs faces the reflective sensor at right angles.
(ホ) 実施例
以下、本考案の実施例を第２図と共に説明す
る。(E) Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIG. 2.
尚、第１図と同一構成要素は同一図番で示して
説明を省略し、本案により改良された点につき説
明する。 Components that are the same as those in FIG. 1 are indicated by the same reference numbers and their explanation will be omitted, and only points improved by the present invention will be explained.
５′が本考案により改良されたガイド板で、反
射型センサ６に対向するよう折曲されて形成され
ている。 Reference numeral 5' denotes a guide plate improved according to the present invention, which is bent to face the reflective sensor 6.
したがつて、紙詰りの発生で記録紙１が繰り出
された場合、記録紙１はガイド板５′により破線
で示すように垂直に繰り出され、反射型センサ６
の放射光線に対し記録紙１が直角に対向される
為、反射型センサ６により確実に紙詰りを検出す
ることができる。 Therefore, when the recording paper 1 is fed out due to a paper jam, the recording paper 1 is fed out vertically by the guide plate 5' as shown by the broken line, and the reflective sensor 6
Since the recording paper 1 faces the radiation beam at a right angle, the reflective sensor 6 can reliably detect a paper jam.
(ヘ) 考案の効果
上述の如く本考案の紙詰り検出装置は、紙詰り
の発生で繰り出された記録紙を反射型センサに対
し直角に対向させるようガイド板を形成したこと
により、紙詰りを確実に検出することができるも
ので、実用的効果大なるものである。(f) Effects of the invention As mentioned above, the paper jam detection device of the present invention is capable of detecting paper jams by forming a guide plate so that the recording paper that is fed out when a paper jam occurs faces the reflective sensor at right angles. It can be detected reliably and has great practical effects.
