Abstract

An attachment mechanism includes a first holding member and a second holding member. The first holding member is configured to hold a device side plate of a belt device to attach a main body side plate of an apparatus in which the belt device is incorporated. The second holding member is configured to be fixed to the first holding member. The first holding member and the second folding member are configured to adjust a posture of the device side plate with respect to the main body side plate in assembly of the belt device.

First claim

What is claimed is:

1. An attachment mechanism comprising:
a first holding member configured to hold a device side plate of a belt device to attach a main body side plate of an apparatus in which the belt device is incorporated; and
a second holding member configured to be fixed to the first holding member, the second holding member including a first engagement slot extending in a first direction and a second engagement slot extending in a second direction, the second direction being different from the first direction, and being configured to rotate about a rotation center axis,
the first holding member and the second folding member being configured to adjust a posture of the device side plate with respect to the main body side plate in assembly of the belt device.

2. The attachment mechanism according to claim 1 ,
wherein the device side plate is engaged with the first holding member at two engagement positions and the first holding member is engaged with the main body side plate at two engagement positions, and
wherein at least one of the engagement positions of the device side plate with the first holding member and the engagement positions of the first holding member with the main body side plate is adjustable in the assembly of the belt device.

3. The attachment mechanism according to claim 1 ,
wherein, in the assembly of the belt device, the first holding member is engaged with the device side plate and the main body side plate when another device side plate of the belt device is attached to another main body side plate of the apparatus.

4. The attachment mechanism according to claim 3 ,
wherein, in the assembly of the belt device, the engagement positions of the first holding member with the device side plate and the engagement positions of the first holding member with the main body side plate are engaged with each other from the same direction in an interval direction between the device side plate and the another device side plate.

5. An apparatus comprising:
a belt device including a pair of device side plates; and
the attachment mechanism according to claim 1 , the attachment mechanism being configured to attach one of the pair of device side plates of the belt device to the main body side plate of the apparatus.

6. A belt device comprising:
an endless belt supported by a plurality of rollers;
a pair of device side plates; and
the attachment mechanism according to claim 1 , the attachment mechanism being configured to attach one of the pair of device side plates to a main body side plate.

7. The belt device according to claim 6 ,
wherein the plurality of rollers includes a steering roller configured to rotate around an axis parallel to a tension direction of the endless belt and a tension roller configured to automatically move in the tension direction to adjust tension in a belt width direction, and
wherein a winding angle of the steering roller between the endless belt is greater than a winding angle of the tension roller between the endless belt.

8. A conveyance device comprising the belt device according to claim 6 , the belt device being configured to convey a sheet.

9. A cooling device comprising:
the belt device according to claim 6 ; and
a cooling unit disposed inside a circulation path of an endless belt of the belt device.

10. A printing apparatus comprising at least one of:
a conveyance device configured to convey a sheet; and
a cooling device configured to cool the sheet,
wherein the conveyance device and the cooling device include the belt device according to claim 6 .

11. The attachment mechanism according to claim 1 , wherein the rotation center axis includes a pin which is insertable into the first holding member.
