Embodiment 1

[0071] exist figure 1 Among them, the symbol 1 represents, for example, a photocopier. The upper surface of the photocopier 1 is assembled with a document pressing plate 2 with an automatic document conveying device. To open and close. On the lower front side of the photocopier 1, a standard paper feeder 3 is provided, and the standard paper feeder 3 accommodates frequently used standard paper such as B5, A4, B4, and A3. The non-standard paper feeding unit 4 is arranged on the right side of the photocopier 1, and the part circled by the arrow A at the entrance 4a of the non-standard paper feeding unit 4 is the bypass tray 5 through the opening and closing device 6. , 6 (showing only one side) are assembled to open and close up and down. In order to correspond to various sizes of paper, a pair of guide elements 5a, 5a are assembled on the upper surface of the bypass tray 5, and the guide elements 5a, 5a are movable and adjustable in a direction perpendicular to the paper feed...

Embodiment 2

[0085] Figure 7 to Figure 11 Other embodiments of the opening and closing device of the present invention are shown. According to the figure, the difference between the opening and closing device 20 of the second embodiment and the opening and closing device 6 of the first embodiment is that the friction mechanism 21 is further provided with a connecting mechanism 32 .

[0086] Others, the structure of the bypass tray 35, or the structure of the opening and closing device 20 may be left or right the same or different structures. In addition, as long as there is no conflict with the first embodiment, the configuration and operation described in the first embodiment can be applied to the second embodiment.

[0087] In other words, as shown in the figure, the inner side of the entrance 4a side of the non-standard paper feeder 4 is particularly as Figure 7 As shown, the rotating shaft rod 22 is assembled. The rotating shaft rod 22 has a deformed part 22a, a flange part 22b and...

Abstract

The invention provides an opening and closing device and an office machine equipped therewith capable of avoiding the impact sound when opening the hand-conveyed tray of the office machine. The opening and closing device comprises a support, a shaft rod, a rotation rod, a locking plate, a fixing washer and a friction mechanism. The support is arranged at the hand-conveyed tray side and the shaft rod is arranged at the office machine side. The rotation rod is inserted through a curved guide groove and the curved guide groove is arranged at the outside of the rotary center of the support. The locking plate fixed to one end of the rotation rod is engaged with the shaft rod. The fixing washer is fixed to the other end of the rotation rod. The friction mechanism is arranged between the fixing washer and the support, which is also arranged between the locking plate and the support.

Description

technical field [0001] The present invention relates to an opening and closing device suitable for use in business machines such as photocopiers, printing machines, facsimile machines, and scanning machines, especially for opening and closing manual trays, and the business machine with the opening and closing device. Background technique [0002] In the above-mentioned various business machines, in order to carry out such as New Year's cards, greetings and notifications for different seasons, and various exhibitions on paper other than B5, A4, B4, A3, etc., such as postcards, envelopes, and thick paper For the printing of notices, etc., the side of the office machine is usually equipped with a paper feeder that feeds these out-of-standard paper into the office machine, and the bypass tray that places the paper fed into the paper feeder corresponds to the aforementioned paper feeder. The part is assembled so that it can be opened and closed in the vertical direction. The byp...
