In order to increase the versatility of copying machines, in addition to the standard automatic paper feeding system, there are already some known manual paper feeding devices that manually feed paper in a desired format from a paper feeding table into the paper feeding line and make copies. It is being In this manual paper feeding device, in order to drive the rollers to rotate and feed the paper from the manual feed table to the conveyance path, a sensor is provided that detects when manual feeding is performed and outputs a signal to drive the paper feeding rollers. ing. As this sensor, a micro switch, a photo sensor, etc. are used, and it is known that there are those provided in front of the paper feed roller, and those provided in both the front and rear stages.
前段にセンサを設ける方式は、構造的には簡単
であるが、センサを手差しされた用紙により動作
させ、それからコロが駆動されるので、紙の差込
みが中途半端であつたり、センサがオンしてから
コロに喰え込まれるまでに時間がかゝると、搬送
路への確実な給紙が実現できなくなる欠点があ
る。 The method of installing a sensor at the front stage is structurally simple, but since the sensor is operated by manually fed paper and then the roller is driven, there is a possibility that the paper may not be inserted halfway or the sensor may not turn on. If it takes a long time for the paper to be bitten by the rollers, there is a drawback that reliable feeding to the conveyance path cannot be achieved.
また、前・後両段にセンサを設ける方式は、前
段のセンサが用紙を検知してコロを駆動してか

かせぎ、後段のセンサが検知してから、一定時
間、コロの駆動を持続することで、搬送路への給
紙を確実にするが、センサを前後、二段に設ける
ためにコスト高となる欠点がある。 In addition, the method of installing sensors in both the front and rear stages allows the time from the time when the front stage sensor detects paper and drives the roller until the paper is detected by the second stage sensor, and the second stage sensor detects the paper to be detected by the second stage sensor. Then, by continuing to drive the rollers for a certain period of time, feeding of the paper to the conveyance path is ensured, but there is a drawback that the cost is high because the sensors are provided in two stages, front and rear.
本考案は、上記事情にもとづいてなされたもの

The present invention was developed based on the above circumstances, and it is possible to realize paper feeding by rollers at the same time as paper detection by a sensor, and manual paper feeding that allows reliable paper feeding without time delay and avoids high costs. The purpose is to provide equipment.

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings. In the figure, reference numeral 1 is a paper feed tray, and at the rear end of the paper feed tray 1, a lower roller 2 with a circular cross section and an upper roller 3 with a part of the circumference cut out are paired. It is arranged. In addition, the paper feed tray 1
A guide 5 is provided at a predetermined paper insertion gap 4, and upper and lower guides 6 and 7 are provided downstream of the rollers 2 and 3 to form a conveyance path 8. A micro switch 9 is provided in the middle of the upper and lower guides 6, 7, close to the rollers 2, 3. And the above micro switch 9
gives a signal to a drive source (not shown) in the ON state to start rotation of the roller 3. Rollo 3 rotates 360° and stops.

As shown in the figure, the paper A is stopped with its cutout surface 3a facing downward, and when paper A is manually inserted from the paper feed table 1, the paper A passes through the rollers 2 and 3.
It reaches the position of the micro switch 9 through the gap. At this point, the actuator 9a is pushed down by the leading edge of the paper and is turned on, causing the roller 3 to start rotating and feed with the circumferential surface 3b of the roller 3. Therefore, the paper feeding length is constant, and paper feeding is reliable.

いう実用上の効果を奏しうる。 As described in detail above, the present invention is to cut the rollers so that a part of the circumferential surface does not touch the paper, so that the paper can be inserted between the rollers before the rollers are driven, and a sensor is used at the downstream stage of the rollers. Since the rollers are driven by detecting manually fed paper, the sensor only needs to be installed in the rear stage, which eliminates the risk of high costs.Furthermore, unlike a system that only installs the sensor in the front stage, there is no paper feeding failure and the system is reliable. A practical effect can be achieved in that the paper can be fed into the conveyance path.
