Operation When the retractable image forming apparatus is opened, the upper body and the lower body are electrically separated, and when it is closed, the upper body and the lower body are electrically connected.

Embodiment FIG. 1 shows a top and bottom electrical connection mechanism of a retractable image forming apparatus according to the present invention, in which a is a side view when the retractable image forming apparatus is closed, b is a side view when it is opened, Figure 2a is a perspective view of the upper connector;
Figure b is a perspective view of the lower connector.

In FIG. 1, 10 is an upper body, 20 is a lower body, 30 is an upper connector, 40 is a lower connector,
50 is a biasing section.

The open/close type image forming apparatus includes an upper body 10 and a lower body 2.
It can be divided into two parts, one end of which can be opened and closed with a hinge. Although not shown, an upper part and a lower part that constitute an image forming apparatus are attached to the chassis 11 of the upper body 10 and the chassis 21 of the lower body 20, respectively.

The vertical electrical connection mechanism of the open/close type image forming apparatus includes an upper connector 30, a lower connector 40, and a biasing section 5.
0, and when the retractable image forming apparatus is closed, the lower connector 40 is biased against the upper connector 30 to establish an electrical connection therebetween.

The upper connector 30 is a male connector, and as shown in FIG. 2a, the upper connector main body 32 is made of resin or the like, and the first electrode 31 of a conductive material is provided on the electrode protrusion 32 at the tip of the upper connector main body 32. and attachment portions 321 provided on the opposite side of the electrode convex portion 32 and at each of the four corners of the connector body 32. This is the opening 3 made in the mounting part 321.
3 to the chassis 11 with screws 34 (see FIG. 1). The first electrode 31 is
They are arranged at equal intervals, and each is connected to an upper part (not shown) by a lead wire or the like, and this is done through the internal space of the upper connector main body 32 and an opening made in the chassis 11. (These are not shown).

The lower connector 40 is a female connector corresponding to the upper connector 30, and as shown in FIG. 2b, the lower connector body 42 is made of resin or the like.
and an electrode recess 4 into which the electrode recess 322 is fitted.
22 and the second electrode 41 provided on the electrode recess 422
, and mounting portions 421 provided at the four corners of the lower connector 42, respectively. This is attached to a connector attachment plate 51, which will be described later, with screws 44 through an opening 43 formed in the attachment portion 421 (see FIG. 1).
The second electrodes 41 are arranged at regular intervals like the first electrodes 31, and each of them is connected to a lower part (not shown) by a lead wire or the like, which is inside the lower connector body 42. This is done through a space and an opening made in the connector mounting plate 51 (these are not shown).

The biasing portion 50 includes a rectangular connector mounting plate 51 to which the lower connector 40 is attached, a spring 52 provided between the chassis 21 and the connector mounting plate 51, and a spring 52 provided on the chassis 21 and connected to the connector mounting plate 51. A protrusion 53 having a semi-elliptic cross-section hinge-connecting both ends of the protrusion 51
, a presser portion 54 having an L-shaped cross section that contacts the upper end of the other end of the connector mounting plate 51 to suppress the extension of the spring 52, and a base that contacts the lower end of the other end of the connector mounting plate 51 and positions it in parallel. It is composed of a plate 55. This is provided to bias the lower connector 40 to the upper connector 30 and firmly connect them when the retractable image forming apparatus is closed. Therefore, in this state, the upper and lower parts (not shown) can be electrically connected. Furthermore, the first and second
Considering the current capacity and insulation properties of the electrodes and their spacing, it is possible to make electrical connections to the power supply system, so the electrical connections between the upper and lower parts can be completely cable-free. be able to.

In this embodiment, such a biasing part is used as a means for biasing the lower connector to the upper connector, but the biasing part is not limited to this, and may be replaced with any other device having the same function. The same applies to upper and lower connectors, and any pair of electrical connectors can be used.

Effects of the invention The upper and lower electrical connection mechanism of the open/close type image forming apparatus according to the invention is provided with a biasing section to bias the lower connector to the upper connector to establish electrical connection. Since these can be assembled and wired independently, automation can be promoted, and work efficiency can also be improved in terms of maintenance.
