Description of the Related Art In an image forming machine such as an electrostatic copying machine and an electrostatic printing machine, in order to supply a sheet member such as plain paper on which an image is to be formed, various sizes generally called "universal type" are used. The sheet member supply cassette which can be applied to the sheet member is advantageously used. Such a cassette includes a container body having a bottom wall, and one or a pair of width regulating means for regulating the position in the width direction of the accommodated sheet member is movably mounted in the width direction on the container body. Have been. Further, the container main body is usually provided with a rear end regulating means for regulating the rear end position of the accommodated sheet member so as to be movable in the sheet supply direction.

まう、等の問題が誘発される。In the above-mentioned universal type sheet member supply cassette, it is important that once the regulating means, especially the width regulating means, is set at a predetermined position, it is held at the predetermined position sufficiently and reliably. Normally, the width regulating means is provided with a claw member which is engaged with the front end corner of the uppermost sheet member of the sheet members housed in a stacked state. When the sheet member is moved or vibrated in the direction, the uppermost sheet member or several sheet members from the uppermost sheet are detached from the claw member and may be positioned above the claw member. And
If such a situation occurs, two or more sheet members are delivered at one time, the delivered sheet members are greatly inclined, or the delivery of the sheet members fails, and the like is caused. .

持することができるようにせしめることが重要である。In recent years, a so-called "front loading" is mounted on a housing of an image forming machine so as to be movable in the front-rear direction between an operation position in the housing and a draw-out position pulled forward from the operation position. The "type" sheet member supply cassette is widely used in practice. In the case of such a front-loading sheet member supply cassette, the sheet member supply cassette is moved in the width direction of the accommodated sheet member, and the sheet member supply cassette is moved at the final stage of the movement from the pull-out position to the operation position. Since the movement of the sheet member tends to be suddenly stopped, a considerable impact is often applied from the sheet member to the width regulating means. Therefore, it is important to ensure that the width regulating means can be held at the predetermined position even when such an impact is applied.

よって、係止部材が規制手段に旋回自在に装着される。In view of the above-mentioned facts, various types of locking mechanisms for holding the regulating means at a predetermined position are also provided in the conventional sheet member supply cassette. A typical example of the conventional lock mechanism is a locking member rotatably mounted on the width regulating means, a stationary locked means provided on the bottom wall of the container body, and an elastic member which elastically moves the locking member in a predetermined direction. And an elastic biasing means for biasing the locking portion to the locked portion of the locked means. A through hole is formed in the locking member, and the locking member is pivotally mounted on the regulating means by inserting the through hole and screwing a set screw into a required position of the regulating means.

迅速に遂行することができない。However, the above-described conventional lock mechanism in the sheet member supply cassette has the following problems to be solved. First, the locking member is usually formed by injection molding or compression molding from an appropriate synthetic resin. However, due to the presence of a so-called undercut caused by a through hole to be formed in the locking member, the molding die is not provided with a slide core or a molding die. It becomes relatively complicated and expensive, including the slide pins, so that the production cost cannot be sufficiently reduced. Secondly, when attaching the locking member to the restricting means, it is necessary to insert a set screw through the through hole of the locking member and screw the set screw to a required position of the restricting means. Therefore, the mounting operation of the locking member cannot be performed easily and quickly enough.

と爪部材との分離が発生してしまう傾向がある。In order to solve the above-mentioned problem in the lock mechanism of the conventional sheet member supply cassette, the present inventors have tried to mold the locking member integrally with the main part of the regulating means from synthetic resin. However, when the locking member is formed integrally with the main part of the restricting means, the restricting means is relatively large due to the elastic deformation of the connecting portion between the main part of the restricting means and the locking member. When an impact is applied, a considerable relative movement is generated between the main part of the restricting means and the locking member, which causes the above-described separation between the sheet member and the claw member to occur. There is a tendency.

In spite of being able to be mounted on the restricting means easily and quickly enough, even if a relatively large impact is applied to the restricting means, movement or vibration of the restricting means can be sufficiently reliably prevented. It is a sham.

First, when the locking member 92 is formed by injection molding or compression molding from an appropriate synthetic resin, since the locking member 92 does not have a so-called undercut, a relatively complicated structure including a slide core or a slide pin is included. The molding can be performed using a simple molding die without requiring a molding die, so that the locking member 92 can be formed at a sufficiently low cost. Secondly, the locking member 9 can be easily and quickly formed by the simple operation as described above without the necessity of operation such as screwing of a set screw, and without the need for a mounting tool.
2 can be mounted on the support shaft 96 as required.
