A rotary drive device is configured to be reduced in size while still delivering a prescribed torque. The rotary drive device has a base part with a vibrating body and a rotating body attached to the base part. The vibrating body has at least one piezoelectric element that vibrates an abutting part, which rotates the rotating body. Specifically, the rotating body has a contact part that is positioned at a prescribed distance from the rotational center and that is abutted against by the abutting part. When voltage is applied to the piezoelectric element, the vibrating body vibrates to repetitively press the abutting part against the contact part to rotate the rotating body. The vibrating body is positioned in a plane that intersects the rotational axis of the rotating body, and is disposed at least as close to the rotational axis of the rotating body as that of the contact part.

A liquid container is for supplying a liquid to a liquid jetting apparatus. The liquid container includes a liquid reservoir section, a sensor and an electrostatic capacitance. The liquid reservoir section stores electrically conductive liquid. The sensor is disposed at a location in the liquid reservoir section, for electrically detecting a condition of the conductive liquid at the location. The electrostatic capacitance is provided between a fixed potential and the conductive liquid, the electrostatic capacitance reducing extrinsic noise.

A charge roller includes a core, a resistive layer disposed on a circumferential surface of the core to charge an image-bearing member without contact, and gap members formed of tape-shaped films. These films are fixed to both ends of the charge roller by winding each of the films in a direction opposite a rotational direction of the charge roller in use and perpendicular to the axial direction thereof to form n layers (wherein n≧2) extending in the axial direction at every position in the circumferential direction of the charge roller. The gap members are pressed against a circumferential surface of an image-bearing member to define a charge gap between the image-bearing member and the charge roller.

An electronic instrument is adapted to communicate with another electronic instrument. The electronic instrument includes an acquisition section, a storage section, an inquiry section and a processing section. The acquisition section is configured to acquire identification information from a managed article used by the electronic instrument, the identification information being read-only information uniquely assigned to the managed article. The storage section is configured to store the identification information acquired by the acquisition section. The inquiry section is configured to inquire another electronic instrument as to whether the identification information acquired by the acquisition section is already stored in another electronic instrument. The processing section is configured to perform processing in response to a result of inquiry by the inquiry section.

Provided is a holder to which a liquid accommodation container can be attached or detached. The holder includes an apparatus side engagement portion, and an opposite wall surface portion. The opposite wall surface portion has a hole portion for inserting a protrusion portion provided in the back surface portion, and a guide groove for guiding the protrusion portion to the hole portion while restricting the movement of the protrusion portion relative to the width direction of the liquid accommodation container when the liquid accommodation container is mounted, the guide groove being extended upward from the hole portion in a usage posture of the holder.

A printing apparatus has a cartridge attachment section including a terminal block having apparatus-side terminals disposed on its inclined surface, and a printing material supply pipe. Among the apparatus-side terminals, one apparatus-side ground terminal located on their center in Y direction is protruded to a greater height than the other plural apparatus-side terminals. A printing material cartridge has a circuit board, a printing material supply port, and a board mount portion that is inclined at an acute angle relative to a plane extended from an opening face of the printing material supply port. The circuit board is arranged such that one cartridge-side terminal on the circuit board comes into contact with the apparatus-side ground terminal prior to the other cartridge-side terminals in the process of attachment of the printing material cartridge to the cartridge attachment section. This arrangement enables the printing material cartridge to be attached in an adequate correct orientation or alignment to the printing apparatus. This arrangement also reduces the possibility of failure caused by application of a high voltage to the circuitry of the printing material cartridge.
