されている。The shaft 34 fixed to the arm 32 described above passes through the elongated hole of the arm support base 31, and is positioned in the axial direction with a flat washer (not shown) and an E-shaped stop ring on the back side of the loosely fitted arm support base 31. The reason for this restriction is that the joint lever 33 strongly pulls the shaft 34 and arm 32 in the direction shown by the traction force of the tension spring 27, which serves to push up the transfer conveyance unit 11 via the lever 24. A moment is generated around the point 36 in the direction of tilting the arm 32 in the direction C in the figure, but a shaft 37 is fixed to the other end of the arm 32 in order to suppress this force. This shaft passes through the long length of the arm stand 38 fixed to the front door 30 and is loosely fitted into it, and is a flat shaft with a larger diameter than the elongated hole (not shown). While keeping an appropriate gap in the axial direction to allow sliding of long pieces using washers and screws, it is fixed with screws from the 1st back side in the C direction.

な配慮をしているものである。This screw can be easily installed and removed. For example, by removing the screw and manually lifting the arm 32 in the direction of the Group 1i'#Fukumae 11tl plate 53 (see Figure 3), the tension can be increased. The transfer/conveyance unit 11 is automatically raised by the traction force of the spring 27, and its position is regulated at a fixed position 7J, so that the copy sheet being fed can be transferred, separated,
This is an effective consideration for service personnel who can observe the transportation status.

If you manually operate the shaft 37 on s a iiB to move it in the direction of opening C from the point where it cannot be opened any further at the end of the long hole of the arm 32, which is the end of the long hole of the arm 32, which is lowered with a screw (not shown). The shaft 37 of the arm 32 moves from the elongated hole 38a of the arm stand 38 in the direction 38b at the other end of the elongated hole. Arm 32 and arm support stand 3 in the same 119
The axis 34, which is also equivalent to the arm 32 and centered on the axis 36 of 1, extends from the long hole 31b of the arm support 31 to the 31
Move while regulating the position of the c-hair arm 32 in the C direction. Furthermore, along with the above-mentioned movement aid, the shaft 34 fixed to the arm 32 and the joint lever 33 that are floating also move in the same direction as the arm 32. This movement causes the transfer transfer inside the main body of the apparatus. Unit 11
The lever 24 located 11μ below begins to rotate clockwise about the shaft 25. A tension spring 27 is tensioned in this direction of rotation, and automatically pushes up the above-mentioned transfer conveyance unit 11 to the reference position 50 or 51 of the side plate of the main body of the apparatus. At this point, 1iiJ and 9430 are in a normal state in which the door gear nut 45 attached to the side plate of the main body of the apparatus and the door gear nut 46 attached to the front door 30 itself are combined to form both parts.

When it is pushed up, it is not shown in FIG. 4, but due to the positional relationship between the transfer guide 54 and the register roller 7, as shown in FIG. The transfer kite 54 is pushed upward by the lever 8c on 'fil' L, which is located at the reference position (not shown).
The axis of the upper roller 7b of the register roller 7, which was fixed at a vapor path position where one image can be formed and placed on the outer frame of the transfer side plate 54a, is aligned along the outer frame outline of the transfer side plate 54a. It is lowered by the roller tension spring 7b,
The upper roller 7a and the lower roller 7b are in close contact with each other. As a result, at the same time that the paper is pushed up and placed in the reference position 50 or 51 of the conveying unit, a paper path is created in which image formation is possible, and image formation becomes completely possible.

Since the front JIS 30 is opened and the transfer conveyance unit 11 and the transfer guide 7 are separated from the photoreceptor 2, the photoreceptor protection cover 1 attached to the unit 1
8 in the direction F, which is the space obtained above, to protect the transfer portion of the photoreceptor 2. According to the copying apparatus of this embodiment, it is possible to protect the transfer portion of the photoconductor 2, and to prevent the occurrence of agent replenishment. Since the unit 1 is pulled out toward the front in the drawing, it is possible to automatically protect the unit 1 from damage caused by outside light or handling.

便利になったという印象を与える事ができる。As explained above, according to this embodiment, the copy sheet conveyance path including the transfer charger near the photoconductor is integrally configured and unitized, and at the same time, the conveyance unit 1 is made swingable.
1, the transfer guide 54 freely swings t7, and enables the presence/absence of a roller gap between the pair of register rollers. The unit and transfer guide can be brought into and out of contact with the photoconductor, and the roller gap of the L' distal roller can be freely brought into and out of contact with rJf, so the operation order and time can be greatly reduced, in addition to jam removal and maintenance. It becomes possible to reduce It can give the operator the impression that one of the basic tasks he has been performing until now has been automated, which made him feel anxious, but now it has become very convenient.
