摘要:
A printer apparatus in the present invention includes a feeding mechanism having a feed roller provided at substantially the same height as an upper face of a medium support means and a plurality of roller assemblies having a pinch roller disposed above the feed roller and a printing medium placed on the medium support means is pinched between the feed roller and the pinch roller to be fed in the front and rear direction. The roller assembly is structured of an assembly main body and a roller member which includes the pinch roller and is attachable/detachable with respect to the assembly main body, and a clamp state can be changed by exchanging the roller member depending on material and/or thickness of the printing medium.

To provide a printer apparatus which is capable of suitably clamping a printing medium of various types of material/thickness, for example, a sheet-like medium and a plate-like medium with a simple structure and is capable of feeding the printing medium accurately. A printer apparatus in the present invention includes a feeding mechanism having a feed roller provided at substantially the same height as an upper face of a medium support means and a plurality of roller assemblies having a pinch roller disposed above the feed roller and a printing medium placed on the medium support means is pinched between the feed roller and the pinch roller to be fed in the front and rear direction. The roller assembly is structured of an assembly main body and a roller member which includes the pinch roller and is attachable/detachable with respect to the assembly main body, and a clamp state can be changed by exchanging the roller member depending on material and/or thickness of the printing medium.

A printer-plotter includes first and second heads which are supported by a guide rail and are movable along a longitudinal direction of the guide rail, independently. A driving member is supported by the guide rail and configured to move along the longitudinal direction between the first head and the second head. A first connecting mechanism is configured to connect the first head to the driving member detachably. A second connecting mechanism is configured to connect the second head to the driving member detachably. The first head is connected to the driving member by the first connecting mechanism and the second head is separated from the driving member in order to make the first head operate. The second head is connected to the driving member by the second connecting mechanism and the first head is separated from the driving member in order to make the second head operate.

A medium transport apparatus includes a feeding roller configured to rotate around a rotational axis. A guide rail extends along the rotational axis. A slider is supported by the guide rail and movable along the rotational axis. A rotatable pinch roller is configured to clamp medium between the feeding roller and the pinch roller to move the medium. A lever is connected to the pinch roller and movable to change a clamping state with respect to the medium between the feeding roller and the pinch roller. An arm is connected to the slider and configured to take an engaging position where the arm moves the lever to change the clamping state when the slider moves along the rotational axis and a standby position where the arm is not engaged with the lever when the slider moves along the rotational axis.
摘要:
A printer-plotter includes a guide rail, a first head, a second head, a driving device, a first connecting mechanism and a second connecting mechanism. The guide rail extends in a longitudinal direction. The first head is supported by the guide rail and movable along the longitudinal direction. The second head is supported by the guide rail and movable independently of the first head along the longitudinal direction. The driving device includes a driving force transmitting member and a driving mechanism configured to move the driving force transmitting member. The first connecting mechanism is configured to detachably connect the first head to the driving force transmitting member. The second connecting mechanism is configured to detachably connect the second head to the driving force transmitting member.
摘要:
According to a prior art data transfer method of a storage subsystem, when competition of data transfer accesses occurs, a free access destination port is allocated uniformly without determining the access type or the access state of the access destination, so that the performance of the device is not enhanced. The present invention solves the problem by selecting a data transfer access for completing data transfer with priority based on the access type or the remaining transfer data quantity of competing data transfer accesses, or by changing the access destination of an access standby data transfer access, thereby performing data transfer efficiently.

Proposed are a storage apparatus and a power consumption estimation method capable of easily and accurately estimating the power consumption of a physical drive without having to use a wattmeter. Operational information concerning a seek amount and a data transfer amount in the relevant hard disk drive which are internally recorded and retained by the respective hard disk drives is collected from each of the hard disk drives, and power consumption of each of the hard disk drives is estimated based on the acquired operational information of each of the hard disk drives.
摘要:
In a storage system including a host computer, and a disk control device connected to the host computer for communications therewith, and performs control over a disk device that stores therein data requested for writing from the host computer, for data transmission from a host interface section or a disk interface section to a memory section, when the data asked by a transmission source for storage is stored in a transmission destination, the transmission destination is put in a first mode for communications of forwarding a response back to the transmission source. With such a configuration, favorably provided is the storage system that offers a guarantee of reliability with the improved processing capabilities thereof.

A fault-tolerant storage system is provided. The storage system is composed of a controller having a plurality of processors and other units. When an error occurs in any one of the components in the controller, the storage system cuts off an I/O path of the controller, specifies the failed component in the cutoff status, and invalidates the failed component. After invalidating the failed component, the storage system determines whether it is operable only with the normal components, cancels (releases) the cutoff of the I/O path when it determines that it is operable, and resumes operation by rebooting.

When data of HDD of computer is backed up to a a data center and a failure occurs in the HDD, the computer notifies failure information to the data center, and the data center stores the backed up data in a storage medium substituting HDD for subsequent delivery. Further, the computer executes processing, using a VNC server, from failure occurrence until recovery.
