る。(Prior art) In a diazo copying machine, when original paper is manually inserted into the insertion slot provided at the front of the copying machine, the photosensitive paper is fed out from the photosensitive paper feeding unit based on a signal from an appropriate original paper detection device. The photosensitive paper is conveyed along with the original paper inserted into the copying machine through a merging passage toward an exposure section of the copying machine.

してしまう事態を生じる。 However, even though the original paper has been inserted, if the photosensitive paper is not fed due to a malfunction in the photosensitive paper feeding section or because the photosensitive paper is not stored in this loading table, only the original paper will be fed. Since it is fed into the copying machine, it not only causes transcription errors but also risks damaging the precious original paper. Particularly, in the case of a diazo copying machine equipped with an automatic separating device including a shifting device, the original paper may be damaged by the automatic separating device.

要がある。 Therefore, if the original paper is configured to stop feeding if the photosensitive paper is not fed even though the original paper has been inserted, the original paper will not be fed alone to the exposure unit or automatic separation device. , it is possible to prevent transcription errors and damage to the original paper. However, in order to achieve such a function, it is necessary to detect whether or not photosensitive paper is fed by some means.

が、給紙ローラー１６によつて送り出される。 In FIG. 1, the original drawing paper 0 is
When inserted through the original drawing paper insertion slot 12, the original drawing paper is fed into the machine by the original drawing paper feeding roller pair 13, and the original drawing paper is inserted by the original drawing paper detecting device 15 disposed in the original drawing paper path 14. This is detected, and based on a signal from the detection device 15, one sheet of photosensitive paper S is sent out by the paper feed roller 16 from the photosensitive paper storage section below the original paper table.

透明円筒２２で構成された露光部に送り込む。 The original drawing paper and the photosensitive paper are led to a merging passage 61,
The leading ends of both sheets of paper collide with a leading edge aligning member 17, which is disposed so that its free end 17a can move forward and backward within this passage.
You can align the tips here. Immediately after the tips are aligned, the alignment member 17 rotates counterclockwise about the shaft 18 to open the merging passage 61, and at the same time, the presser roller 20, which had been separated upward from the feed roller 19, moves to the feed roller 19. The original paper and the photosensitive paper, which are pressed against each other and overlapped, are fed into an exposure section composed of an endless belt 21 and a transparent cylinder 22 for exposure.

る。 The original paper 0 and the photosensitive paper S that have passed through the exposure section are guided by a guide receiving plate 27 and fed into a shifting device 30 consisting of a pair of rollers 28 and 29 rotating in the directions of the arrows. Of the pair of rollers, the roller 28 on the side that contacts the original paper has a circumferential speed that is approximately the same as the paper feed speed in the exposure section, and the other roller 29, that is, the roller on the side that makes contact with the photosensitive paper, has the paper feed speed in the exposure section. It is rotated at a circumferential speed somewhat higher than that of the Therefore, the original paper and photosensitive paper fed into the shifting device advance with the leading edge of the photosensitive paper ahead of the leading edge of the original paper.

る。 The leading edge of the preceding photosensitive paper is separated from the original paper by a separating rotary plate 31, and then separated by a roller 32,
Guide path 33, roller pair 34, swingable guide plate 35, roller 36, guide plate 37, roller 3
After passing through a roller pair 38 consisting of rollers 8a and 38b and being fed into the developing section 39 and developed there, the lower guide plate 40 and the upper guide section 41 are used as copy paper.
The copy paper is discharged onto a copy paper tray 43 by a pair of copy paper discharge rollers 42 . on the other hand,
The original paper separated from the photosensitive paper is discharged onto an original paper holder (not shown) by a pair of rollers 44.

を生じる。 When the original paper is inserted through the original paper insertion slot 12, the paper feed roller 16 rotates in the direction of the arrow based on a signal from the original paper detection device 15, and the photosensitive paper S is sent out. If the photosensitive paper is not fed even though the original paper has been inserted, due to a malfunction in the paper feeder or because the photosensitive paper is not stored in the loading table, only the original paper will be fed into the copier. This may not only lead to transcription errors but also damage the precious original paper. Particularly, in the case of a copying machine equipped with an automatic separating device including a shifting device, the original paper may be damaged by the automatic separating device.
このような不具合を回避するために、原図紙が
挿入されたにも拘わらず、感光紙が給送されない
場合は、感光紙の不給紙を検知して差し込まれた
原図紙の搬送を停止すべく、原図紙送り込みロー
ラー対１３を自動的に停止する。 In order to avoid such problems, if the photosensitive paper is not fed even though the original paper has been inserted, the system detects the non-feeding of the photosensitive paper and stops the feeding of the inserted original paper. Therefore, the pair of original paper feed rollers 13 is automatically stopped.

が得られない。 In order to detect whether or not the photosensitive paper has been fed,
That is, in order to detect the absence of photosensitive paper that should merge with the original paper passing through the merging path 61, as shown in FIG. A light absorbing member 261 of black color, for example, which has a lower light reflectance than the above, is fixed, and this occupies a position inside the advancing original paper in the merging passage 61, and below the tip of this light absorbing member 261. is attached to the lower guide plate 260b of the photosensitive paper, and a light emitting element 262 and a light receiving element 263 (FIG. 3) are arranged facing the merging path 61 and occupying a position outside the photosensitive paper traveling through the merging path. When the photosensitive paper is fed along the lower surface of the light absorbing member 261, light from the light emitting element 262 is reflected on the back surface of the photosensitive paper and enters the light receiving element 263, thereby detecting the presence of the photosensitive paper. . If the photosensitive paper is not present below the light absorbing member 261, the light from the light emitting element 262 is absorbed by the light absorbing member 261, so that reflected light sufficient to activate the light receiving element 263 cannot be obtained.
このようにして、感光紙の給紙、不給紙を検知

つて行うことができる。 In this way, feeding or non-feeding of the photosensitive paper is detected, and if the photosensitive paper is fed, the original paper conveying device consisting of a pair of original paper feed rollers 13 is activated, and the photosensitive paper is fed. If not, the driving of the original paper conveying device is cut off and the device is stopped. To stop the original paper conveying device, the roller 13a transmits rotation to the roller 13a or cuts off rotation transmission.
This can be done by turning off a clutch located on the shaft of the

になつている。 In FIG. 2, when the leading edge aligning member 17 is closed, the leading edges of the original paper and the photosensitive paper are aligned by the aligning member 17, but in this case, the photosensitive paper is Since there may be a situation where the sheets advance toward the alignment member 17 with a predetermined deviation behind the original paper, the light emitting elements 262, The photosensitive paper detection sensor consisting of the light receiving element 263 is arranged at a position on the near side of the alignment member 17 corresponding to the amount of deviation.
