摘要： PURPOSE:To validate the speediness of a zone bit system by recording a data block on the optimum zone or in the neighborhood of the zone according to attribute data. CONSTITUTION:An address signal conversion part 1 inputs a R/W signal 5, a logic address 6, and the attribute data 7 from an input/output channel 12, and converts the address 6 to a physical address 10 by using a disk working status summary list 13 and a logic address/physical address conversion list 14 stored in a memory 2. The attribute data 7 consists of the priority of a user, a user ID, and a zone No., etc., and supplies a fast zone in sequence of high priority, and that of high priority of an user ID level. Thereby, data can be written on the appropriate zone according to the attribute data, and the optimum arrangement of the data to a fast outer peripheral zone or a slow inner peripheral zone can be easily performed, which validates the speediness of the zone bit system.

摘要： PURPOSE:To shorten the time of pattern generation by storing a character pattern and control information at the end of character pattern generation processing in the character pattern storage area and sequential file area of a pattern storage means. CONSTITUTION:When a CPU 21 reports the end of pattern generation processing, the control circuit 36 of a character generator (CG) 10 reads a pattern out of a buffer memory 25 and outputs it to the CPU 21, and the pattern is written and stored in the system information storage area 11 of the sequential file area different from the character pattern storage area 23 of a floppy disk (CD) 23 as the pattern storage means through a selector 13 together with the control information. The storage contents are utilized for next retrieval and the access time is shortened to shorten the pattern generation time of a CG-FD type character generator.

摘要： PURPOSE:To prevent memory capacity reduced due to the defect of a storage area by providing a selection circuit to select one of remainder out of plural disk recording planes and to perform read/write when a defective track or a defective selector is detected. CONSTITUTION:When the defect exists on a recording plane, a microprocessor 6 sends a defect signal to both a disk control part 5 and a head selection circuit 10. The disk control part 5, when receiving the defect signal, writes defect information on a flag byte when writing ID information. Also, the head selection circuit 10, when receiving the defect signal, selects a head number on a record ing plane for alternation prepared in advance instead of the head number on the recording plane where the defect exists, and the write or the readout of data is performed on a corresponding alternate track or alternate sector. There by, it is possible to remarkably prevent the memory capacity reduced due to the defective track or sector appearing prominently by parallelization.

摘要： PURPOSE:To transfer data at high speed by providing a host interface, a disk interface which performs the input/output of stored data in parallel to a storage disk, and a means which controls the transfer of data between both interfaces. CONSTITUTION:A host interface 2 is provided to perform the input/output of data for which a host device 1 has an access together with a disk interface 4 which performs the input/output of the stored data in parallel to a storage disk 10, and a means which control the transfer of data between both interfaces 2 and 4. Therefore the input/output of data stored in the disk 10 is carried out via the interface 4 in the form of the parallel data. At the same time, the transfer of data is carried out between both interfaces 2 and 4. Thus, it is possible to transfer of data on a disk device at high speed via a single LSI.

摘要： PURPOSE:To prevent the inverting of the reading image of upper and lower surfaces by providing a mechanism to revolve a onedimensional image sensor, whose reading direction is one direction, by 180 deg. in a scanning direction. CONSTITUTION:The mechanism is obtained to execute the reading of the upper and lower surfaces of an image reader with the revolution of an optical system and to revolve the reading direction of a sensor 101 by 180 deg. in the scanning direction with accompanying the inversion of the upper and lower surfaces. Namely, the image of an original 113 set in a reading window 112 is reflected by a reflecting mirror 104 and the image is read by the image sensor 101. The image of an original 113a set in a reading window 112a is read, while the image sensor 101 is revolved by 180 deg., with accompanying the revolution of the reflecting mirror 104 by 90 deg.. Thus, even when the reading of the upper and lower surfaces of the image reader is executed, a correction by other devices is eliminated.

摘要： PURPOSE:To enable a mirror image to be printed by use of a printer for general use, by providing a means for switching a normal image and a mirror image from one to the other, and a means for reversing the vertical relative moving directions of a printing head and a printing material. CONSTITUTION:It is presumed that a printing head is fixed with respect to vertical directions and a printing material is moved upward at the time of printing a normal image. When a mirror image printing switch 18 is set in a mirror image position, a moving direction-reversing circuit 19 reversely rotates an LF (line feed) motor 7, whereby the head is moved downward. In the case of a line printer, merely performing the above operation results in that characters be printed are printed in the form of mirror images inverted upside down without any change in printing information. When the printing material is rotated by 180 deg. and observed, the printed result as a whole is a mirror image. In the case of a matrix printer, a means is further provided for converting the vertical positional relationships of dots of a printing head, as compared with those in the case of printing a normal image, whereby the characters to be printed can be printed in the form of mirror images inverted upside down without any change in printing positions.

摘要： PURPOSE:To enable an entire mirror image printing in the print result, by providing means for switching execution between positive image printing and negative image printing, means for detecting that a print head is at the rightmost end, and means for inverting the print head. CONSTITUTION:A print control section 1 provides an address information to CG17 at a print start position, while it provides a print front information to a parallel/series converting section 5 in order to covert the print font information into a serial signal, and a head drive section 7 drives a print head 6 so as to carry out positive image printing from left to right. When mirror image printing is selected by means of a switch 19, a drive direction inverting circuit 18 inverts drive pulses fed from an SP motor drive section 11 and provides the inverted drive pulses to an SP motor 10, and an extreme end switching section 21 provides information fed from a rightmost end switch 20 to the print control section 1. If a print start information is provided to the print control section 1 through a print information line 13 under this state, the print head 6 moves from right to left untill the switch 20 detects that the print head 6 has reached to the rightmost end. Since the print head 6 has the printing function only in the direction of a row, the entire mirror image in the print result can be obtained upon inversion of moving direction.

摘要： PURPOSE:To enable accurate printing and cutting operations to be simultaneously performed, by providing a printing head comprising printing needles and cutting needles and a mechanism for retracting an ink ribbon from a position between the printing head and a printing paper, and performing both printing on the paper and cutting of the paper. CONSTITUTION:A cutting operation is performed only in a cutting mode, that is, only when printing code data is a printing code for cutting. At the time of switching from a printing mode to the cutting mode, a controlling part 1 selects cutting needles 29 of a printing head 24 provided with the cutting needles through a needle-selecting circuit 22 and a printing driving circuit 3, and drives an SP motor 5 through an SP motor driving circuit 6 to effect a one-dot-pitch rightward movement where the cutting needles 29 are located at the left of printing needles 30. Then, a lifting motor 25 is driven to turn a ribbon cassette 16 upward together with 8 cassette lifter 27, whereby an ink ribbon is retracted from a position between the head 24 and a printing paper 12. The cutting needles 29 are driven through the printing driving circuit 3.
