Abstract

(57) [Summary] [Structure] A transparent plate 3 is pivotally supported by a shaft 2 at one end of a support base 1 so as to be openable and closable, and is positioned in parallel by a positioning pin 4 on the other end. In order to maintain parallelism between the document mounting table 7, which is urged in the vertical direction by the shaped spring 6, and the transparent plate 3, a holding mechanism consisting of a plate shaped spring 9 having a hook 11 and a holding pin 10 is provided. [Effect] Since the transparent plate is held parallel to the document table, the problem that the document is distorted when being read is solved.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a high-resolution facsimile machine in which the original is placed on a flat surface. Concerning improvements to holding stands.

0002

[Conventional technology]

Conventionally, this type of document holding table has a supporting table 21 and a document placing table 2, as shown in FIG. 7, use the pin 25 as a guide to hold the original table 27 perpendicular to the transparent plate 23 side. When the transparent plate 23 is opened and closed using the shaft 22 as a fulcrum, an elastic member 26 is provided to hold the transparent plate 23. A positioning pin 24 for positioning the transparent plate 23 parallel to the document mounting table 27 is attached to the supporting table. 21, and was configured to press and hold the original 28.

0003

[Problem that the idea aims to solve]

In the conventional document holding table described above, the document 28 is placed on the document placing table 27. , since the transparent plate 23 was closed and the document 28 was pressed and held, the following There are drawbacks. Close the transparent plate 23 to place the original 28 on the original placing table 27 At this time, the transparent plate 23 is not held parallel to the document table 27, and the document 28 cannot be read. A problem arises in that the original 28 is distorted when being read.

0004 The purpose of this invention is to provide a document holding table that holds a transparent plate and a document placing table in parallel. There are many things.

[0005]

[Means to solve the problem]

The present invention consists of a document placing table mounted on a support stand, and a front plate that can be opened and closed on the side of the document placing table. a transparent plate that is pivotally supported on the support base and holds the original between it and the original support base; Provided between the support stand and the original document placing table, with the original placing table facing the transparent plate side. an elastic member that holds the transparent plate vertically; A document holder comprising a positioning pin for positioning a plate parallel to the document mounting table. The table includes a holding mechanism for holding the transparent plate and the document mounting table in parallel. The holding mechanism includes a leaf spring provided on the end surface of the support base and a front and a retaining pin provided at one end of the transparent plate and engaged with the leaf spring. In addition, a hook is provided at the tip of the leaf spring to elastically engage with the holding pin. It's okay to be kicked.

【Example】

Next, the present invention will be explained with reference to the drawings.

[0007] FIG. 1(a) is a sectional view showing a document holding table according to an embodiment of the present invention, and FIG. 1(b) is a sectional view showing a document holding table according to an embodiment of the present invention. FIG. 3 is an enlarged side view showing the holding mechanism in this embodiment.

[0008] The document holding stand of this embodiment is opened and closed by a support stand 1 and a shaft 2 at one end of this support stand 1. A transparent plate 3 that is pivotably supported and a plurality of positioning pins provided on the other end of the support base 1 A pin 5 having a plate spring 6 at the lower end and fixed to the side surface of the support base 1 is proposed. A box-shaped document mounting table 7 that is movable vertically as an interior, and a box-shaped document mounting table 7 provided on the other end surface of the support table 1. A plate spring 9 having a hook 11 and a holding pin provided at the other end of the transparent plate 3. 10. The transparent plate 3 is supported by a shaft 2 at one end of the support base 1, and is can be opened. Note that the transparent plate 3 is free from optical distortion due to a transparent body such as a glass plate. The parallelism on both sides is well-finished to prevent this from occurring. The plurality of positioning pins 4 A plate spring 9 is provided on the other end of the support base 1, and a retaining pin is provided on the other end surface of the support base 1. 10 are provided at the other end of the transparent plate 3, respectively. This closes the transparent plate 3. When the lower surface of the transparent plate 3 hits the positioning pin 4 and the holding pin attached to the transparent plate 3 10 is engaged and held by a plate spring 9, and the transparent plate 3 stands still in parallel to the document mounting table 7. However, the distance between the transparent plate 3 and the original table 7 is always kept constant.

[0009] Next, the operation of the document holding table according to this embodiment will be explained. Place original 8 on the original It is placed on the stand 7, and then the transparent plate 3 is closed in the direction of arrow A as shown in FIG. 1(a). child At this time, the tip of the holding pin 10 shown in FIG. The plate spring 9 hits the hook 11 of the plate spring 9, and the plate spring 9 moves along the shape of the holding pin 10 as shown by the arrow. It rotates in the BB' direction. When the transparent plate 3 is completely closed, the elastic force of the plate spring 9 , the hook 11 engages and holds the holding pin 10, and the transparent plate 3 is held flat against the document table 7. It stays stationary in a row, and the spacing remains constant.

0010 When opening the transparent plate 3 in the direction of arrow A', lift the transparent plate 3 in the direction of arrow A'. Then, the plate spring 9 rotates in the direction of arrow BB' along the shape of the holding pin 10, and the transparent plate 3 opens.

[0011]

[Effect of the idea]

As explained above, the present invention provides a holding mechanism for the transparent plate. When the transparent plate is closed, the transparent plate is held parallel to the document mounting table, so the original is This has the effect of preventing the manuscript from being distorted.
