Description

[Detailed Description of the Invention] LLL to Tag 1 The present invention is composed of upper and lower structures that are pivotally connected to each other at one end, and connects the electrical parts provided in each structure to connect both structures. The present invention relates to an image forming apparatus that is used in a closed state.

As illustrated in FIGS. 4(a) and 4(b), image forming apparatuses such as refillable laser printers, electrophotographic copying machines, and facsimile machines are equipped with a It is divided into an upper structure 1 and a lower structure 2, which are pivoted to each other at either the left or right end or the rear end 3, and are opened as shown in the figure (b) for maintenance inspection and replacement of parts. (a) As shown in the figure, there is one that is operated by being closed. In an image forming apparatus having such a configuration, electrical components such as a power supply unit, a control unit, a motor operated by these units, and an operating unit such as a static eliminator are provided separately in both upper and lower structures, and when operating the apparatus, It is necessary to have both the upper and lower structures in a locked state, and to connect the electrical equipment installed on both bodies to each other.

Conventionally, both I! The electrical components provided in the structures 1 and 2 are usually connected to each other by connecting harnesses (cords) connected to the electrical equipment of each electrical component using connectors so that they can be connected to and separated from each other. Therefore, as shown in FIG. 5, the connectors 6 are concentrated at the connecting part Af:f between the harness 4 from the upper structure 1 and the harness 5 from the lower structure 2, requiring a large space and making the connection work difficult. Also, when opening and closing the device itself, tensile or bending stress is applied to these harnesses, causing the connectors to become disconnected, or
There are problems such as the harnesses not being able to reach each other and being unable to connect, or the structure pinching the harnesses when opening and closing, causing damage, and the design has to be redone to prevent such things from happening. It happened often.

The present invention is intended to solve the above-mentioned problems of the conventional means for connecting electrical parts of an image forming apparatus, which is composed of upper and lower structures pivotally connected to each other at one end, and to solve the problem of problems at the time of connection and harnesses at the time of opening and closing. An object of the present invention is to provide an image forming apparatus that prevents damage to the image forming apparatus.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the image forming apparatus of the present invention is fixed to both structures as means for connecting the electrical parts of the upper and lower structures, and is separated when both structures are opened. However, it is characterized in that it is provided with a pair of male and female connectors that are connected when closed.

JL With this configuration, when the upper and lower structures are closed, the male and female connectors fixed to the respective structures are automatically connected, and the electrical parts of both structures are connected. By opening the upper and lower structures, it is possible to omit the harness to which the connectors are connected, and it is possible to prevent problems during assembly and damage to the harness when opening and closing the structure.

When the signal line and the power line are provided in separate connectors that are independent of each other, it is desirable for safety to separate the power line after the signal line when disconnecting the connectors.

Therefore, it is preferable to provide the power supply connector at a position closer to the pivot joint of the upper and lower structures than the signal connector.Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a diagram showing a first embodiment of an image forming apparatus to which the present invention is applied.

A female connector (jack>10) is fixed to the upper structure 1, and a male connector (plug) 11 is fixed to the lower W4 structure 2 at a position corresponding to the female connector 10.Male and female connectors 10. 11, as shown in detail in FIG. 2, the male connector 11 is provided with a plurality of bottles 11a protruding from it, and the female connector 10 is provided with a recessed portion 10a that can receive each of the bottles 21a. There is.

The recessed part 10a has the bottle 11a vertically I! with respect to the recessed part 10a. When moving in an arc around the pivot axis of the corpse and engaging and disengaging, it is constructed of spring plates that elastically clamp the bottle lla from both sides, for example, so that it can be held and disengaged without force. There is.

Wiring from each part of the electrical equipment section of the upper structure 1 to each part of the electrical equipment part of the lower structure is concentrated in a female connector 10 and connected to a recessed part 10a forming each contact point. In addition, the wiring from the electrical equipment section of the lower structure 2 is connected to the male connector 1 correspondingly.
1 and connected to each bin 11a.

Therefore, when the upper and lower structures 1 and 2 are closed, the corresponding bottles lla and recesses 10a of the male and female connectors 10.11
are connected to each other, and the electrical components provided in the upper and lower structures 1.2 are electrically connected via connectors 10.11.

Therefore, there is no need for a harness with a connector that is separated from the structure and connected to the tip, which eliminates the above-mentioned problems caused by providing such a harness, and also reduces costs by eliminating the need for a long harness. is also helpful.

FIG. 2 is a diagram showing a second embodiment of the present invention. In this embodiment, for the purpose of preventing signal noise, etc., the signal line and the power supply line are connected in a concentrated manner to a pair of connectors provided at different parts of the structure. The male and female connectors 20 and 21 for the power line are the connectors 30 for the signal line.
．． 31, it is provided at a position closer to the pivot shaft 3 of the upper and lower structures 1 and 2. Each connector engages and disengages while moving in an arc around the pivot shaft 3, so when the upper and lower structures 1 and 2 are closed and engaged, the connector 20 of the power line located near the pivot shaft 3 .21 starts contacting earlier than the signal line connectors 30 and 31, and when the upper and lower structures 1.2 are opened and removed, conversely, the signal line connectors 30 and 31 are removed first, and then The power line connectors 20 and 21 are disconnected.

The reason for this configuration is that if the power supply line is cut off first, there will be a problem in the circuit.

As described above, according to the present invention, the electrical components provided in the upper and lower structures can be connected to the upper and lower structures using only the pair of connectors fixed to the upper and lower structures, respectively, without using complicated harnesses. The connector can be separated and connected by opening and closing the body, which eliminates assembly problems that occur when a connector that is separated from the structure is provided at the end of the harness, which also contributes to cost reduction.

In addition, when the connectors for the signal line and the power line are provided independently from each other, safety can be ensured by providing the connector for the power line closer to the pivot axis of the upper and lower structures than the connector for the signal line. be able to.
