BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning material for packing, and more particularly, to a cushioning material for packing a unit mounted on a main unit.

[0002]

2. Description of the Related Art In general, recent electrical products are of a type in which a unit device is prepared as an option with respect to a main body device, electrically connected via connection terminals, and integrally connected to each other by a connector. Many have been developed. For example, in an image forming apparatus such as a copying machine, a facsimile, a page printer, or the like, a sheet feeding device is provided as an option as a unit device in order to increase the number of sheets fed to the main unit.

Here, in a unit device such as a paper feeding device which requires a relatively large installation area, in order to prevent the installation area from increasing even when the unit device is mounted on the main unit,
2. Description of the Related Art A configuration in which connection terminals and positioning members are provided on an upper surface of one device and a lower surface of the other device, and a unit device and a main body device are vertically opposed to each other has been widely adopted.

[0004]

When the above-described main unit and the unit unit are connected, it is necessary that the connecting terminals and the positioning members of the two units be exactly vertically opposed to each other. However, since the connection terminals and positioning members of the device arranged on the upper side are formed on the lower surface, it is not possible to visually observe the facing state of each connection terminal and the like, and it is difficult to position the connection terminals. There is a problem that it is extremely difficult to accurately set and connect them. In addition, when the upper device is placed on the lower device in a state where the positioning is inaccurate, the connection terminals and the like may be damaged. For this reason, there was a problem that the serviceman had to connect the unit devices.

The present invention has been made in view of the above-described problems, and has as its object to provide an improved cushioning material for packaging so that even a user can accurately connect a vertically opposed main unit and a unit device. And

[0006]

Means for Solving the Problems The present invention to solve the above described problems is the packaging buffer material for packaging units device coupled to the main body apparatus, slow for the packaging
Unpacking the packing case that packs the unit device through the impact material
Sometimes, it is characterized in that it comprises a guide capable of guiding part of the connection between the main unit and the unit device.

[0007]

According to the packing cushioning material having the above-described structure, when unpacking the unit device, the main device and the unit device are connected while the guide device is being moved along the main device, so that a special positioning mechanism is not provided. Both can be easily connected.
