Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application) The present invention relates to a connector holding device, and more particularly to a connector holding device capable of dealing with this.

(Prior Art) FIG. 1 shows a schematic diagram of the drum and periphery of a copying machine having a conventional one-component developing device.

In the figure, l is a drum, and around the drum 1 is a one-component developing machine 2. Transcription corotron3. Peeling corotron 4.
Cleaning equipment @5 + band N:] O) Long 6 etc. are provided. The reflected light 7 from the original is irradiated onto the drum 1 which is uniformly charged by the charging corotron 6. As a result, an electrostatic latent image is formed on the drum 1.

The electrostatic latent image is developed by toner supplied from the mag roll 2a of the one-component developing device 2, and is transferred by the transfer corotron 3 onto copy paper fed from the direction of arrow 8. The transferred copy paper is then moved in the direction of arrow 8' and is fixed.

FIG. 2 shows a perspective view of a conventional single-component developing machine 2. As shown in FIG.

Side plates 11 and 12 are fixed to the sides of the developing machine 2, and mag rolls 2a are inserted into holes provided in the side plates 11 and 12.
A rotating shaft 13 is rotatably inserted therethrough. Rotating shaft 13
Said side plate 11. On the outside of 12 (ma, bearing 14
, IB' are provided with plastic rings 16, 17. This plastic ring is -component developing machine 2
During the operation, it comes into contact with the surface of the drum 1 and maintains the distance between the mag roll 2a and the surface of the drum 1 at an accurate length.

As mentioned above, during operation, the plastic ring attached to the -component developing machine 2 and the drum 1 are in contact with each other.
When detaching the -component developing machine 2, the -component developing machine 2
It is not possible to draw it directly towards a person. That is, when pulled out in the inward direction, the plastic rings 16 and 17 rub against the surface of the drum 1, causing damage to the drum surface.

Therefore, when pulling out the single-component developing device 2 from the copying machine in the operating position of the copying machine, first move it in the direction of arrow B, which is perpendicular to the direction of arrow A, so that the surface of the drum 1 and the plastic ring l come into contact with each other. After releasing the button, move it in the direction indicated by the arrow. On the contrary, when installing the -component developing device 2 in its operating position, it is first moved in the direction opposite to arrow A, and then moved in the direction opposite to arrow B, contrary to the above operation. Then, install the developing machine 2 in the position shown in Figure 2.
I try to bring it with me.

The problem at this time is how to connect the connector on the one-component developing machine side for supplying power to the -component developing machine 2 to the connector fixed on the copying machine main body frame side. . Conventionally, the -component developing machine used a manual connector to move in two directions.

For this reason, there are drawbacks in that the work is cumbersome and connections may be forgotten.

(Objective) The present invention has been made in order to eliminate the above-mentioned drawbacks, and its object is to provide a connector holding device that allows the connector to be connected easily and prevents the connector from being forgotten.

(Summary) In order to achieve the above object, the present invention attaches an electrical coupling connector to a main body frame so as to be movable in a predetermined direction, and applies a tensile force in the predetermined direction to prevent disconnection. The feature is that the connector is sometimes returned to a predetermined position.

(Example) The present invention will be described in detail below with reference to the drawings.

FIG. 3 is a perspective view of one embodiment of the present invention.

- A power drawer connector 21 is fixed on the side plate 12 of the -component developing machine 2. On the other hand, frame 2 of the copier main body
2, the other drawer connector 23 is slidably mounted in a guide groove 24 provided in the frame 22. The external drawer connector 23 is biased with a force in the direction of arrow C by, for example, a spring 25. The biasing of the spring 25 in the direction of the arrow C is restricted by the drawer connector 23 being locked to a stopper (not shown) and the movement of the drawer connector 23 in the direction of the arrow C.

In FIG. 1, symbols other than those mentioned above indicate the same things as in FIG. 2. Although the side plate 12 and the frame 22 are shown separated in FIG. 3 for ease of understanding, they are actually close to each other, and when the -component developing device 2 is operating, the drawer connector 22 and 22 are connected to each other. That is, one V lower connector 22 is fitted into the other drawer connector 23.

Next, the operation of this embodiment will be explained. When the -component developing machine 2 is to be removed from its operating state, the -component developing machine 2 is first moved in the direction of arrow B in the figure. At this time, the drawer connector 21
and 23 are in a connection relationship, so the drawer connector 23 moves into the guide groove 24 as the single-component developing device 2 moves in the direction of arrow B.
It moves in the force direction of arrow IB or in the direction of arrow C.

The developing machine 2 and the drawer connector 23 are separated by a predetermined distance.
After being moved in the direction of arrow B, the developing device 2 is then pulled out in the direction of arrow A. At this time, one drawer connector 21
The other drawer connector 23 is unfitted and separated electrically and mechanically. In addition, the drawer connector 23
Exactly at this time, it is stopped by the aforementioned stopper and movement in the direction of arrow C is prevented. Therefore, it is stopped at this position.

Contrary to the above Iζ, when installing -component developing device 2, -
Push the component developing device 2 in the direction opposite to the direction of arrow A. When the side plate 12 is pushed in a predetermined length, the side plate 12 approaches the frame 22, and the drawer connector 21 fixed to the side plate 12
The stopper and the other drawer connector 23, which had been stopped at a predetermined position, are fitted together. by this,
The drawer connectors 21 and 23 are mechanically and electrically connected.

Next, when the -component developing device 2 is moved in the direction opposite to the direction of arrow B, the drawer connector 23 moves in the guide groove 24 in the direction opposite to arrow C against the force of the spring 25. When the -component developing device 2 is stopped from moving by a stopper (not shown), the developing device 2 comes to the position shown in FIG. 3 and becomes ready for operation.

FIG. 4 is a diagram showing the mutual relationship between the drawer connectors 21 and 23 when the one-component developing device 2 is installed from a different angle in the same manner as described above. When the developing device 2 is moved in the force direction A' opposite to the direction of the arrow A, the drawer connector 21 fixed to the side plate 12 (O) is pulled by the spring 25.
The drawer connector 23 is engaged with a stopper (not shown) and is fixed to the frame 22, which is waiting at a predetermined position. After connecting the drawer connector,
The developing device 2 is moved in the direction B' opposite to the arrow B. At this time, the drawer connector 23 is connected to the frame 22
The spring 2 is guided by a guide groove bored in the spring 2.
5 and moves in the direction of arrow B'. Then, as described above, the developing device 2 is set at a predetermined position.

In the above embodiments, the present invention has been explained by taking a -component developing machine as an example, but the present invention is not limited to a developing machine, and when attaching and detaching,
Of course, the present invention can be applied to any device that requires movement parallel to the frame and movement perpendicular to it.

(Effects) According to the present invention, the drawer connector attached to the frame returns to a predetermined position and stands by when a device is attached or detached. Therefore, when the device is attached, it is automatically connected to the connector on the device side. Furthermore, after being fitted into the connector on the equipment side, it can be moved in the same direction as the equipment and in a direction parallel to the frame. Therefore, working time can be significantly shortened and connections will not be forgotten.
