A socket for an electrical part to prevent a bad electrical connection with a circuit by preventing a deformation of a tip of a contact pin. The contact pin of the present invention comprises one terminal contacts to a terminal of the electrical part and the other terminal contacts to the circuit. When a tip of the other terminal is pressed to a substrate under a state that first and second holes of first and second holding plates are shifted each other, an upper terminal of the held portion of the other terminal contacts to a lower surface of the second holding plate, and makes the second holding plate to separate from the first holding plate against a spring force of a urging member. At this time, the portion projecting from the lower surface of the first holding plate toward the substrate moves into the first hole.

A clamp for a disk rotation driving device has a centering hole which is fitted to an outer circumference of a centering projection of a hub of the disk rotation driving device. A clamping screw is screwed into an axial center of the hub whereby a fastening head of the clamping screw fastens the clamp to the hub and a contact portion of the clamp comes in contact with an information recordable magnetic disk attached to the hub and presses onto the disk in a rotation axis direction. The clamp includes a centering cylinder bent in an axial direction. The centering cylinder has a circumferential inner surface which defines the centering hole. The rounded section is provided along an edge of the centering hole and has a radius smaller than the thickness of the centering cylinder. The fastening surface is continuous to the rounded section.

An image forming device includes a replaceable cartridge, a light-emitting element, a light-receiving element, and a determining unit. The replaceable cartridge accommodates developer therein and includes an agitator and a developing roller rotatable together with the agitator. The light-emitting element is configured to emit a light toward the replaceable cartridge. The light-receiving element is configured to receive the light emitted by the light-emitting element through the replaceable cartridge to output a signal. The determination value is produced based on the signal. The determining unit is configured to determine whether or not the determination value is greater than a predetermined determination threshold upon the agitator having rotated continuously more than a first prescribed number of times. The determining unit determines that the replaceable cartridge should be replaced with a new one when the determination value is greater than the predetermined determination threshold.

The present invention has a support member which rotatably supports a reel by supporting the outer periphery of the reel at least two positions and a posture restriction member (a pair of wall members or press roller) which restricts a posture of the reel supported by the support member. As another example, the reel is rotatably held in the hold member, and the hold member is supported by the support member and its posture is restricted by the posture restriction member. As still another example, the reel is arranged between a pair of wall members and the reel is pivotally supported by inserting the support member which has a support shaft which is suitable to be inserted detachably in an insertion hole provided in at least a pair of wall members.

An image forming device includes a light-receiving element that receives a light having passed through a cartridge. An image forming unit has a first mode for forming images while rotating an agitator at a first speed and a second mode for forming images while rotating the agitator at a second speed that is lower than the first speed. If a value regarding image forming amount counted while the image forming unit is in the second mode is determined to be greater than a predetermined value, the image forming unit changes a rotation speed of the agitator from the second speed to the first speed, and it is determined whether the cartridge should be replaced based on a time ratio, which is a ratio of time duration, in which the light-receiving element receives the detection light within a predetermined duration, to the predetermined time duration.

Bobbin case containing a lower thread bobbin mounted in a rotary hook of a sewing machine is exchanged for a new bobbin case by the bobbin case being transferred between the rotary hook and a bobbin stock section provided apart from the rotary hook. Transfer mechanism reciprocatively transfers a bobbin grasping device, grasping a bobbin case at a distal end portion of a chuck section, between the rotary hook and the bobbin stock section. In a predetermined position of a transfer stroke of the bobbin grasping device, an orientation change mechanism changes the orientation of the chuck section, being transferred toward the rotary hook, so that the chuck section faces toward the rotary hook, and changes the orientation of the chuck section of the bobbin grasping device, being transferred toward the bobbin stock section, so that the chuck section faces toward the bobbin stock section.

A driving force distribution device includes a sub transmission, a friction clutch, a rotary drive member fixed to an output shaft of an actuator, a friction clutch driving cam to change a pressing force of the friction clutch, a shift cam to shift the sub transmission by converting rotary motion of the actuator into linear motion, and a ratchet lever provided so that a shaft line thereof in a normal direction with respect to the outer surface of the rotary drive member is a rotation center. The ratchet lever is disengaged from the shift cam and is rotated when the rotary drive member is rotationally driven to one side from a predetermined position starting at control origin of the shift cam, and the ratchet lever is rotated in conjunction with the shift cam when the rotary drive member is rotationally driven in a direction opposite to the one side.

A developing device includes a casing having an opening extending in a first direction, a developing roller, a thickness-regulation member, an engagement portion and a sealing member. The thickness-regulation member includes a thin-plate member and a regulating portion. The thin-plate member is fixed to the casing and has a lateral end extending in a second direction. The regulating portion is fixed on the thin-plate member and has an end face extending in a direction. The engagement portion is fixed on the thin-plate member and positioned closer to the lateral end than the end face to the lateral end to provide a groove between the engagement portion and the end face. The sealing member is fitted in the groove and has a length in the first direction longer than a length of the groove prior to assembly of the sealing member into the groove.

A balancer is fixedly attached to a rotary input shaft of a crank mechanism that converts rotary drive of a needle bar drive source to up-and-down motion of a needle bar. The balancer is caused to rotate at substantially an opposite phase with respect to up-and-down motion of the needle bar with the rotary drive of the needle bar drive source. When the balancer is driven at substantially the opposite phase with respect to the up-and-down motion of the needle bar, inertia force in an up-and-down direction of the needle bar, generated due to the up-and-down motion of the needle bar is negated, whereby it is possible to reduce vibration generated in the up-and-down direction. Sewing heads paired with each other by being arbitrarily combined are controlled so as to be rotationally driven to cause rotational directions of the needle bar drive sources to become opposite directions to each other.
