An inkjet recording apparatus ejects ink from recording heads to a recording paper, thereby attaching the ink to the medium for recording. The apparatus includes a carriage driving motor, a transfer motor, a scanner which reciprocates a carriage having the recording heads in a scanning direction, and a transfer machine. The transfer machine transfers the recording paper in a transfer direction perpendicular to the scanning direction. Both of the motors are located at approximately the same place in an ejecting direction of ink from the heads to the paper, and at the same height of a transfer path of the paper or on the carriage side with respect to the transfer path.

An inkjet recording apparatus ejects ink from recording heads to a recording paper, thereby attaching the ink to the medium for recording. The apparatus includes a carriage driving motor, a transfer motor, a scanner which reciprocates a carriage having the recording heads in a scanning direction, and a transfer machine. The transfer machine transfers the recording paper in a transfer direction perpendicular to the scanning direction. Both of the motors are located at approximately the same place in an ejecting direction of ink from the heads to the paper, and at the same height of a transfer path of the paper or on the carriage side with respect to the transfer path. A single ink supply tube supplies ink in a greater amount per unit time than other ink supply tubes. At least a part of the ink supply tube has a larger diameter than the other ink supplies tubes.

A disk holding device of a thin design is provided which can positively hold disks of different thicknesses, and also can automatically align the disk. The disk holding device includes a plurality of claw-like members, a center hub receiving the claw-like members therein, resilient members which are received in the center hub, and respectively urge the claw-like members in a radial direction of a disk, a turntable for supporting the disk thereon, a cone ring which is provided at a lower side of the center hub, and is movable along an axis of a spindle shaft and an urging member urging the cone ring in a disk-unloading direction away from an upper surface of the turntable. The cone ring has a slanting portion for engagement with a center hole portion of the disk, and each claw-like member is received in the center hub in such a manner that the claw-like member is slidable in the radial direction of the disk, and is angularly movable in the disk-unloading direction. With this construction, a force, required for loading and unloading the disk, is small, and therefore the deformation and strain of the disk can be kept to a minimum. And, the disk holding mechanism and the disk alignment mechanism can be combined into an integral construction, thereby achieving a thin design of the disk holding device.
