本発明は、複写機等の画像形成装置本体に装着
する用紙等のシート用カセツトのシート取出し用
開閉蓋を該シート用カセツトの着脱時に自動的に
開閉するようにしたシート給送装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an automatic opening/closing method for opening/closing a sheet ejecting lid of a sheet cassette, such as paper, which is attached to the main body of an image forming apparatus such as a copying machine, when the sheet cassette is attached or removed. The present invention relates to a sheet feeding device that opens and closes automatically.

As a conventional sheet feeding device, there is one shown in FIG. 4, for example, which includes a cassette main body 1 that stores copy paper, and a cassette main body 1 that is located at the upper part of the cassette main body 1 and that is used when the cassette main body 1 is inserted into and removed from the cassette mounting opening 2a. A sheet take-out lid 3 that can be slid to open and close, a cassette cover 4 thereof, a metal protrusion 3a protruding from the tip of the lid 3, and an upper end of the mounting opening 2a of the copying machine body. A magnet member 5 is provided for locking the protrusion 3a.

装着作業が簡易化できる。 In the above configuration, in order to install the sheet cassette main body 1 with the opening/closing lid 3 in the closed state into the image forming apparatus main body, hold the cassette main body 1 with both hands and insert it into the installation opening 2a. Since the opening/closing lid 3 slides to the right and the front part of the cassette cover 4 is opened, the mounting of the cassette main body 1 is completed. Since the opening/closing lid 3 of the cassette cover 4 opens as the cassette main body 1 is installed in this way, the work of installing the cassette main body 1 can be simplified.

However, in the case of the conventional sheet feeding device, when the cassette main body 1 is pulled out, the protrusion 3a is removed during the pulling operation due to the pulling force exceeding the attraction force of the magnet.
may separate from the magnet member 5, resulting in a situation where the cover is not completely closed. That is, the cassette main body 1 is frequently attached and detached in the image forming apparatus, and the degree of withdrawal varies depending on the operator, and there is a problem that the opening/closing lid 3 is half-opened when the cassette main body 1 is detached from the magnet member 5 described above. There were many.

The present invention has been made in view of the above, and includes a spring-like locking mechanism on the main body of the image forming apparatus in order to reliably close the sheet cassette when attaching and detaching it, regardless of the condition of the operator's attachment/detachment operation. A sheet feeding device is provided in which a member is provided and the elastic force of the locking member is used to engage and disengage a protrusion provided on the cassette side.

い。 That is, in this embodiment, the sheet cassette main body 1 is composed of a cassette cover 4 fitted on its upper part, and an opening/closing lid that is slidable to open and close when the cassette main body 1 is attached or removed is provided in the front part of the cassette cover 4. 3 is provided. A metal protrusion 3b is erected at the tip of the opening/closing lid 3, and a spring-like locking member 21 is provided at the upper end of the mounting opening 2a of the image forming apparatus main body. The protrusion 3b provided on the cassette side can be engaged and disengaged by utilizing this. In addition, for example, the slide member or the opening/closing plate is always elastically biased to close, and when the slide member or the opening/closing plate is engaged with the engaging portion of the image forming apparatus main body, it opens against the elastic force as the cassette is inserted. You may also do so.

Similarly to the above, the opening/closing lid 3 shifts to the closed state relative to the main body 1 (Fig. c). When the opening/closing lid 3 is completely closed and the cassette main body 1 continues to be attached to and removed from the image forming apparatus main body, the protrusion 3b resists the elastic force of the locking member 21 and separates from the locking member. Then, the attachment and detachment of the cassette main body 1 is completed (d
