Possibly supported. A locking groove 6 is formed at the other end of the roller support plate 4. 6' is a locking groove formed in the side plate 1' of the first main body 1, and both locking grooves 6, 6' are used when the roller support plate is in the fixed position, that is, when the roller support plate is in one of the supported positions. The rollers are configured to communicate when the roller is in contact with the other fixing roller. Reference numeral 7 denotes a first operating stick, which is integrally formed with a second operating stick 7' and forms an operating lever in a substantially dogleg shape. A locking piece 8 such as a rod or pin is provided. Reference numeral 9 denotes a sliding member such as a spring attached to the first operating rod 7 of the operating lever, and is always attached in the direction in which the locking piece 8 moves toward the locking groove 6' formed on the side plate of the first main body 1.

によつて容易に設定することができる。 With the structure described above, when the second main body 2 is closed, the pressing member 10 is pressed against the second operating rod 7' of the operating lever.
In order to press the roller support plate 4, the locking piece 8 provided on the first operating rod 7 moves toward the locking groove 6 side of the roller support plate 4, and presses the other end of the roller support plate 4 downward.
Therefore, one roller supported by the roller support plate 4 comes into pressure contact with the other roller provided on the first main body 1 side, so that the fixing device is set in a normal state. Note that the contact pressure between the upper and lower rollers of the fixing device can be easily set by considering the length of the pressing member and the formation of the operating lever.

接係止忘れがなくなる。 When the first body 1 and the second body 2 are opened, as shown in FIG. 2, when the second body 2 is opened upward, the pressing member 10 releases the pressure on the second operating rod 7' of the operating lever. , the first operating rod 7 of the operating lever is pulled in the biasing direction of the elastic member 9, and the locking piece 8 provided on the first operating rod engages with the locking groove formed in the side plate 1' of the first main body. 6' side, the roller support plate 4 is released, and one roller 16 of the fixing rollers is released from pressure contact with the other roller 17. Since the roller support plate 4 can be opened in the direction of the arrow around the shaft 5 at one end, paper jammed in the fixing device can be easily removed. Also,
In this case, by opening the second main body, the pressure locking of the roller support plate is automatically released.
This saves the trouble of releasing a separately provided locking mechanism when opening the fixing roller, and when setting the fixing roller to the normal state, by closing the second body, the pressing member operates the operating lever to support the roller. Since the plate is automatically pressed and locked, there is no need to forget to press and lock the fixing roller.
さらに本発明の構成について第３図を用いて説
明を加える。 Further, the configuration of the present invention will be explained using FIG. 3.

材との接触関係を保つように構成されている。 In the figure, reference numeral 18 indicates a locking piece 9 provided in the middle of a locking groove 6' formed in the side plate 1' of the first main body 1.
When the second main body 2 is opened in normal use, the locking piece 8 is stopped at this stopper. In this state, the locking piece 8
The second operating rod 7' of the operating lever is configured to maintain contact with the pressing member.

ることができる。 Next, when the second operating rod 7' of the operating lever is pushed in the direction of arrow A, the locking piece 8 passes over the stopper 18 and is locked at the deepest part of the locking groove 6'. At this time,
The second operating rod 7' of the operating lever is in the position shown by the dotted line and is configured so as not to come into contact with the pressing member 10. Therefore, in this state, even if the second main body is closed, the operating lever is not pressed and the fixing roller remains released from pressure contact. In other words, you can prevent the fixing roller from deforming by leaving it in this state until it is installed for use or during transportation.When it is installed for use, operate the operating lever to position the locking piece in front of the stopper. If you do this, you can automatically lock and release the fixing roller by pressing it.
また、係止溝６，６′の形状は直線的に形成し
てもよいが、図示の如く略円孤状に形成すると係
止片の停止位置が決まり易くなつて望ましい。 Further, the locking grooves 6, 6' may be formed linearly, but it is preferable to form them in a substantially circular arc shape as shown in the figure, since this makes it easier to determine the stopping position of the locking piece.

いる。Effects of the Invention As detailed above, according to the present invention, a locking groove that communicates with the roller support plate supporting one roller and the side plate of the first main body is formed, and a locking groove located within the locking groove is formed. An operating lever with a stopper and a locking piece attached to the first
It is composed of an operating lever attached with an elastic member biased to move toward the side plate of the main body, and a pressing member that operates this operating lever when opening and closing the second main body, and the operating lever is pressed by the pressing member. The locking piece moves and presses into the locking groove of the roller support plate, and when the second body is opened and the pressure of the pressing member on the operating lever is released, the urging force of the elastic member Since the locking piece is automatically moved to the side plate side, when the second main body is closed, the fuser is automatically set to the normal state, and when the second main body is opened, the roller support plate's presser is automatically set. Since the lock is released, it becomes easier to remove the paper jam, and it is possible to prevent forgetting to set the fixing device. In addition, by locating the locking piece beyond the stopper and at the deepest part on the side plate side, the pressure on the fixing roller can be released until it is installed for use or during transportation. Roller deformation can be prevented. Furthermore, since it has an automatic press locking and releasing structure, it has many effects such as saving the labor and effort involved.
