Abstract
Example embodiments include a driving device having: a plurality of vibrating members that may vibrate when the vibrating members are driven; and a holding part that may hold the vibrating members. The holding part may include a first member with which one or more of the vibrating members may be brought into contact, and a second member with which one or more of the vibrating members may be brought into contact. The first member and the second member may be partially coupled to each other. A grounding member for electrically grounding a member held by the holding part may be brought into contact with one of the first member and the second member that is more difficult to vibrate.
Claims13
A driving device comprising:
- a driving source;
- a drive transmitting member configured to transmit driving force from the driving source to a driven body;
- a housing that houses the drive transmitting member in a recess of the housing;
- a first member disposed on an opening side of the recess of the housing;
- a second member disposed opposite the housing across the first member, wherein the driving source is disposed opposite the first member across the second member;
- and
- a first grounding member for electrically grounding the driven body and a second grounding member for electrically grounding at least the driving source are provided in the first member,
- wherein the first member has a shape that is more difficult to vibrate than the second member.
A driving device, comprising:
- a driving source;
- a drive transmitting member configured to transmit driving force from the driving source to a driven body;
- a housing that houses the drive transmitting member in a recess of the housing;
- a first member disposed on an opening side of the recess of the housing;
- a second member disposed opposite the housing across the first member, wherein the driving source is disposed opposite the first member across the second member;
- and
- a first grounding member for electrically grounding the driven body and a second grounding member for electrically grounding at least the driving source are provided in the first member,
- wherein the first member and the second member each include a first through hole through which a first fixing member fixing the first member and the second member to the housing extends,
- wherein a relative position between the first member and the second member is fixed at a fixing portion by the first fixing member extending through the first through hole of the first member and the first through hole of the second member to be fastened to the housing,
- wherein the first member and the second member are coupled at three or more fixing portions, and
- wherein, inside a polygon defined by the three or more fixing portions,
- the driving source abuts against the second member, and
- at least one supporting member supporting the drive transmitting member or at least one shaft of the driven body abuts against the first member.
A driving device, comprising:
- a driving source;
- a drive transmitting member configured to transmit driving force from the driving source to a driven body;
- a housing member housing the drive transmitting member;
- and
- a first member and a second member between the driving source and the housing member,
- wherein
- the first member and the second member each include at least three through holes through which separate, respective fixing members fixing the first member and the second member to the housing member extend, and a relative position between the first member and the second member is fixed at separate fixing portion of three or more fixing portions by a fixing member of the separate, respective fixing members extending through one through hole of the first member and one through hole of the second member to be fastened to the housing member, and
- inside a polygon defined by the three or more fixing portions,
- the driving source abuts against the second member, and
- at least one supporting member supporting the drive transmitting member or at least one shaft of the driven body abuts against the first member.
