The present invention relates to an electrostatic chucking device having an electrostatic chucking plate that stacks and holds a plurality of objects to be attracted and holds sheet-shaped objects to be attracted by this electrostatic attraction force.

[Prior Art] An electrostatic holding means for holding and holding an object to be adsorbed by using the Coulomb force of static electricity induces an adsorption mechanism by applying positive and negative charges to a set of electrodes by energization, and this adsorption mechanism. The object to be adsorbed is held by the electrostatic attraction force of.
Such an electrostatic holding means is used in mechanical equipment in various industrial fields, for example, by being provided in a document holding portion of a copying machine or a conveyed object holding portion of a conveyor device.

[Problems to be Solved by the Invention] By the way, in an electrostatic chucking device having a conventional electrostatic chucking plate, an electrostatic chucking plate sucks and holds an object to be chucked at a desired position, and is used as a bulletin board or document holder. Has been done.

However, none of the above-mentioned electrostatic attraction plates were used for temporary storage.

That is, when storing a large sheet such as A0 or A1 size as an object to be adsorbed, in order to adapt the object to be adsorbed to the indoor temperature and humidity environment, conventionally, a large paper is hung on the erected rod-shaped member, Alternatively, it is placed flat on a flat plate to prevent wrinkles and broken lines from appearing on the paper.

However, when the paper is hung on the erected rod-shaped member, the storage space is small, but the paper has a tendency to be folded, which makes it difficult to use the paper.

Further, if the paper is stored flatly, the storage space becomes large, and the space cannot be effectively used, which is disadvantageous in practical use.

Furthermore, even if the electrostatic adsorption device is used for storage, it does not require temporary storage, for example, a large storage area for the object to be adsorbed for backup is required, and the storage space becomes large, which is not practical. There is an inconvenience of being disadvantageous.

Therefore, in order to eliminate the above-mentioned inconvenience, the object of the present invention is to stack a plurality of objects to be attracted onto the electrostatic attraction plate of the electrostatic attraction device while slightly moving the upper end portion of the objects to be attracted upward. By forming a plurality of vertical attracting portions that extend in the horizontal direction on the surface of the electrostatic attraction plate to attract, and by providing a storage portion for temporarily storing a sheet-shaped object to be attracted under the vertical attracting portion, A storage space for a plurality of objects to be attracted is reduced, an accommodation space for the objects to be attracted is not required, and an electrostatic attraction device having an electrostatic attraction plate for stacking and attracting a plurality of objects to be attracted, which is practically advantageous, is realized. It is in.

[Means for Solving the Problems] In order to achieve this object, the present invention attracts and holds a sheet-shaped object to be attracted by a pair of electrodes and an electrostatic attraction force induced by the pair of electrodes. In an electrostatic attraction device having an electrostatic attraction plate, the pair of electrodes are arranged in a comb shape on the electrostatic attraction plate, and a plurality of objects to be attracted are moved while slightly moving an upper end portion of the objects to be attracted upward. A plurality of vertically adsorbing portions that extend in the horizontal direction are formed on the surface of the electrostatic adsorbing plate in order to adsorb them in a stacked manner, and a storage portion for temporarily storing the sheet-shaped object to be adsorbed is provided below the vertical adsorbing portions. It is characterized by being provided.

[Operation] With the above-described configuration, when the attracted objects are stacked and attracted to the electrostatic attraction plate of the electrostatic attracting device, the attracted objects stored in the storage section are taken out one by one and the attracted objects are removed. While slightly moving the upper end part of the above, a plurality of adsorbents are sequentially stacked and adsorbed on a plurality of adsorbing parts extending in the horizontal direction to reduce the storage space of a plurality of adsorbents and store the adsorbents. No need for space.
