Description

Description: TECHNICAL FIELD The present invention relates to a glass plate supporting mechanism for a document placing table in a copying machine or the like, and more particularly to a glass plate supporting member which can support a glass plate without damaging an edge thereof. Regarding the plate support mechanism.

2. Description of the Related Art In a copying machine or the like, as shown in FIGS. 1 and 2, a contact glass plate 100 as a document placing table has a pair of opposite edges 101 and 102 formed by a supporting table 103 made of aluminum or the like. Supported and fixed. Since this support base 103 presses both end surfaces 101 and 102 strongly in opposite directions to sandwich and fix the glass plate 100 in a sandwich shape, stress is applied to the edges 104 and 105 included in these end surfaces 101 and 102, respectively. concentrate. As a result, these edges 104 and 105 are chipped or cracked during transportation of the copying machine. Such damage to the contact glass 100 causes defective products, and its solution is strongly desired.

It is an object of the present invention to provide a glass plate supporting mechanism for a document placing table in a copying machine or the like, which can prevent damage to the edge of the glass plate. Another object of the present invention is to provide a glass plate supporting mechanism for a document placing table in a copying machine or the like in which the glass plate can be easily attached. Still another object of the present invention is to provide a glass plate supporting mechanism for a document placing table in a copying machine or the like, which has a simple structure and can be easily manufactured by extrusion or pressing.

SUMMARY OF THE INVENTION A glass plate supporting mechanism of a document placing table in a copying machine or the like according to the present invention includes a pair of glass plate supporting members respectively supporting a pair of opposite side edge portions of a glass plate, and one glass plate supporting member. Supports the two surfaces forming one edge on one side edge portion while straddling one edge, and the other glass plate support is positioned diagonally on the side surface of the glass plate. The two surfaces forming the edge are supported so as to straddle the edge of the other side edge portion, and the above-described object is achieved thereby.

Embodiments Embodiments of the present invention will be described below.

As shown in FIG. 3, the glass plate supporting mechanism of the present invention includes a glass plate 2 used for placing an original on an original placing table of a copying machine, and one side edge of the glass plate 2. And a glass plate support 1 for supporting the portion. The other side edge portion of the glass plate 2 is supported by the glass plate support 1 shown in FIG.

The glass plate support 1 shown in FIG. 3 includes a first support means 11 for supporting one surface of one side edge portion 20 of the glass plate 2 to be supported, for example, an upper surface 21, and an upper surface together with the upper surface 21. Second supporting means 12 for supporting the end surface 22 constituting the edge 200 of the.

The first supporting means 11 mainly presses and supports the glass plate 2 from above to below (from upper surface to lower surface). In order to impart elasticity to the first supporting means 11, it is preferable that the first supporting means 11 is brought into contact with the surface of the glass plate at an appropriately inclined angle.

The second support means 12 mainly presses and supports the glass plate 2 in the plate surface direction. The second supporting means 12 is composed of a plurality of protrusions formed by press working, and each protrusion is elastically point-contacted with the end face 22 of the glass plate. If a ridge is formed instead of the protrusion, it can be brought into line contact with the glass plate. Needless to say, this case also has elasticity.

Since the glass plate support 1 has such a structure, the support 1 does not contact the glass plate edge 200.

FIG. 4 shows the glass plate support 1 that supports the other side edge of the glass plate 2. This supporting tool 1 is also a first supporting means for supporting the lower surface 23 of the other side edge portion 20 of the glass plate 2 and the lower edge 20 together with the lower surface 23.
And a second support means 14 for supporting the end face 24 which constitutes 0.

Since this support tool 1 is provided with the notch 10 along the edge 200 of the edge 20 of the glass plate to be supported at the corners of the two orthogonal surfaces, without touching the edge 200 of the glass plate,
The glass plate 2 can be surface-supported.

The glass plate support 1 shown in FIG. 3 and the glass plate support 1 shown in FIG. 4 are applied to a pair of opposite side edges of the glass plate 2, respectively, and the glass plate 2 is attached. Support and fix. In this way, by supporting the opposite side edges of the glass plate 2 by the respective support tools 1, the upper edge 200 of one side edge 20 and the edge 200 of the other side edge 20 are supported. As a result, a force is applied in the diagonal direction in a state where the lower edge 200 located in the diagonal direction is removed and the glass plate 2 can be firmly supported. The support 1 is obtained by extruding a light metal such as aluminum.

Effect of the Invention The glass plate supporting mechanism of the document placing table in the copying machine of the present invention uses the glass plate supporting member configured to support the glass plate in the plane, line or point without touching the edge in this way. Therefore, it is possible to minimize edge damage.

Each glass support is capable of firmly supporting the glass plate without damaging each edge, because a force is applied in the diagonal direction of the glass plate in a state where each edge located in the diagonal direction of the glass plate is removed. it can. Since each glass plate support member supports only one of the respective end faces of the glass plate, and the upper surface and the lower face which together with the end face form an edge portion not supported by the support member at each end face, Only one support is in contact with the upper surface of the plate.

Therefore, if such a glass plate supporting mechanism is used for a document placing table of a copying machine or the like, the document can be slid from the side of the glass plate supporting member that is not in contact with the upper surface of the glass plate, and the document is placed. And easy to remove.

Further, since the structure is remarkably simple, it can be easily manufactured by extruding, molding or pressing aluminum or resin.
