４を起動する。 Thereupon, the paper feed device A is installed at its paper feed unloading section 11
is attached to the cassette loading port 10 and attached to the copying machine, and the paper feeding means 4 is activated upon receiving a paper out signal from the sensor 16.
この起動と同時にジヤムタイマーを作動し、所
定時間経過して用紙先端がセンサー１６に到達し
ないときジヤムと判定するようにしてある。 A jam timer is activated at the same time as this activation, and a jam is determined when the leading edge of the paper does not reach the sensor 16 after a predetermined period of time has elapsed.
また紙載台１にはエンプテイーセンサー１７が
通常の構造で取付けてある。 Further, an empty sensor 17 is attached to the paper table 1 in a normal structure.
そしてこの給紙装置Ａでのジヤム判定時及び紙
載台１の用紙無し検出時に、その信号を次のよう
に複写機本体５に伝達するようになつている。 When the paper feeding device A judges a jam or detects that there is no paper on the paper tray 1, the signal is transmitted to the copying machine main body 5 as follows.
まず複写機本体５のカセツト装填口１０に延設

る。 In such a structure, when the paper feeder A is installed in the cassette loading port 11 of the copying machine main body 5, the actuator S2 of the switch means S1 first moves the shutter plate 12 provided on the exit guide 14 of the paper feeder A. , and the switch means S1 is held in the paper present state. (See FIG. 2) At the same time, a sensor 16 disposed on the exit guide 14 detects the absence of paper at the entrance roller 15. Then, the paper feeding means 4 is activated by this signal, and the uppermost paper of the stacked papers 3 on the paper stack 2 is fed out and sent to the exit guide 14. When the leading edge of this paper reaches the sensor 16, the signal causes the paper feeding means 4 to
stops. The paper prepared on the entrance roller 15 of the copying machine main body 5 is fed into the apparatus by the entrance roller 15 rotating in response to a paper feed instruction signal for the copying process.
この用紙後端がセンサー１６から外れると、こ
のセンサー１６の用紙無し信号に応答して給紙手
段４が起動し次の用紙を入口ローラ１５に送る。 When the trailing edge of the paper comes off the sensor 16, the paper feeding means 4 is activated in response to the paper out signal from the sensor 16 and feeds the next paper to the entrance roller 15.
そこで給紙装置Ａの紙載台２上に用紙が無くな
るとエンプテイーセンサー１７がこれを検知す
る。 Therefore, when there is no paper on the paper tray 2 of the paper feeder A, the empty sensor 17 detects this.

ヤムタイマーで所定時間内にセンサー１６が用紙
を検知せずジヤム（ノンフイード）を検知する。 On the other hand, if a paper jam occurs between the paper feed means 4 and the entrance roller 15, or a so-called non-feed occurs in the paper feed means 4, the sensor 16 is activated within a predetermined time by the jam timer from the start of the paper feed means 4. Detects jam (non-feed) without detecting paper.
このエンプテイー信号及びジヤム信号を受け
て、シヤツター板１２のソレノイド１３に通電さ
れ、シヤツター板１２は第３図の状態にスイツチ
手段S1のアクチユエーターS2から退避する。 In response to this empty signal and jam signal, the solenoid 13 of the shutter plate 12 is energized, and the shutter plate 12 is retracted from the actuator S2 of the switch means S1 to the state shown in FIG.
するとこのスイツチ手段S1は用紙無しの状態を
検知して複写機本体５に複写動作の禁止と用紙無
しの表示を行なさしめる。 Then, this switch means S1 detects the state of no paper, and causes the copying machine main body 5 to prohibit the copying operation and display that there is no paper.
