Abstract
A drive device includes a drive motor including a rotation shaft, a sensor unit including a slit disk in which is formed a plurality of slits and a sensor that detects the slits, and a holding member, wherein the slit disk is attached to the rotation shaft and the drive motor and the sensor are attached to the holding member.
Claims12
A drive device comprising:
- a drive motor including a rotation shaft, the rotation shaft comprising:
- a first rotation shaft protruding from a first end face, which is one end of the drive motor, and
- a second rotation shaft protruding from a second end face, which is an other end of the drive motor;
- a sensor unit including a slit disk in which is formed a plurality of slits and a sensor that detects the slits;
- and
- a holding member, wherein
- the slit disk is attached to the rotation shaft,
- the drive motor and the sensor are attached to the holding member,
- the drive motor is a cantilever structure fixed to a frame at the first end face,
- the slit disk is attached to the second rotation shaft,
- the drive motor includes
- a first flange section that serves as a bearing of the first rotation shaft and
- a second flange section that serves as a bearing of the second rotation shaft, the holding member includes
- a chassis section along a shaft direction of the rotation shaft, a first extension section that extends from one end of the chassis section in a direction intersecting the shaft direction and that includes a first engaging section configured to engage with the first flange section, and
- a second extension section that extends from an other end of the chassis section in a direction intersecting the shaft direction and that includes a second engaging section configured to engage with the second flange section, and
- the first extension section is fixed to the frame in a state where the holding member is held by the drive motor.

A drive device comprising:
- a first pulley;
- a second pulley;
- a timing belt stretched between the first pulley and the second pulley;
- a drive motor configured to drivingly rotate the first pulley;
- and
- a belt regulating section that regulates a shifting movement of the timing belt, wherein
- the belt regulating section has a regulating face formed along an outer peripheral surface of the timing belt at a position where the timing belt is stretched around the first pulley, the regulating face is present over a region of 180 degrees or more occupied by an arc section of the timing belt at a position of the first pulley.

A drive device comprising:
- a first pulley;
- a second pulley;
- a shaft member coupled to the first pulley and disposed in a direction along a rotation axis of the first pulley;
- a bearing that rotatably supports the shaft member;
- a frame to which the bearing is attached in a state of being inserted into an insert section;
- a detachment restriction section that restricts movement of the bearing in a direction that the bearing detaches from the insert section;
- a timing belt stretched between the first pulley and the second pulley;
- a drive motor configured to drivingly rotate the first pulley;
- and
- a belt regulating section that regulates a shifting movement of the timing belt, wherein the belt regulating section has a regulating face formed along an outer peripheral surface of the timing belt at a position where the timing belt is stretched around the first pulley.
