点があつた。 The transfer paper peeling and conveying device of a conventional copying machine has a means for peeling off the transfer paper sent to the transfer position of the photoreceptor (e.g., by blowing air or using a nail) and transferring the peeled transfer paper to the next step of fixing. It consisted of a conveyance means (e.g. vacuum suction belt, etc.) to send it to the process,
The peeling means is unreliable and often causes peeling errors, and the conveyance means is also large-scale.

られている。 In FIG. 1, the transfer paper 5 transferred to the transfer process is transferred by a transfer corotron 1a when it passes between the photosensitive drum 1 and the transfer paper conveyance belt 2, as in the conventional apparatus. In the transfer paper peeling and conveying device of the present invention, a soft flat tongue piece 3 is provided on the transfer paper conveying belt 2 provided at a position corresponding to the end of the photosensitive drum 1, and the transfer paper A cam plate 4 is provided on the conveyor belt 2.

間を通過し定着される。 The leading edge of the transfer paper 5 transferred to the transfer process passes through the pressure contact portion of the photosensitive drum 1 and the transfer paper conveyance belt 2 while being held between the transfer paper conveyance belt 2 and the tongue piece 3, and then the transfer paper 5 is guided by a cam plate 4, passes between a heat roll 6 and a pressure roll 7 in the next step, and is fixed.

好ましい。 By the way, the tongue piece 3 is biased so that the free end of the tongue piece 3 can rise from the belt surface in order to sandwich the transfer paper, so that after carrying out the transfer paper transfer operation, the tongue piece 3 can immediately move on to the next transfer operation. Must have been. Furthermore, since it comes into contact with the photosensitive drum 1, a material that does not damage the photosensitive drum 1 is required. For this reason, the tongue piece 3 is preferably made of soft elastic rubber, and more preferably made by integral molding with the transfer paper conveyance belt 2.

ともできる。 In the actual transfer process, it is necessary to adjust the timing between the tongue piece 3 and the leading edge of the transfer paper. That is, when image formation is performed synchronously with the rotation of the photosensitive drum 1, the circumferential length of the transfer paper conveying belt 2 is an integral multiple of the drum circumferential length, tongue pieces 3 are provided at equal intervals, and the belt is adjusted to the timing. If the belt is rotated in synchronization with the photosensitive drum 1, there is no need for control.
Furthermore, if image formation is not performed synchronously with the rotation of the photosensitive drum 1, a micro switch is installed in the tongue piece 3.
It is also possible to provide an actuator to stop the tongue piece 3 at a predetermined position or to make it run slowly, and to bring the transfer paper conveying belt 2 up to the circumferential speed of the photosensitive drum by actuating the actuator using the leading edge of the transfer paper. .

置が簡単で経済的であるという利点を有する。 As is clear from the above description, in the transfer paper peeling and conveying device of the copying machine according to the present invention, the transfer paper is sandwiched between the conveyor belt and the tongues, so that the peeling action is reliable, and the tongues are made of a soft material. Since the photosensitive drum is created, there is no damage to the photosensitive drum, and the structure described above has the advantage that the device is simple and economical, such as not requiring a large-scale device such as a vacuum suction belt. have
