Abstract: After a numbering character string is input, the start position of the numbering character string to be serially incremented and the end position of the numbering character string to be repeatedly incremented and printed on a print tape are set, and the number of print tapes on which the input numbering character string is serially implemented and printed is set. In this case, a numbering character string to be printed on a first print tape and a numbering character string to be printed on a last print tape are displayed on a liquid crystal display before the start of printing.

Abstract: In such a manner that ink in each of a plurality of pressure chambers for holding the ink therein is brought to a positive pressure state of being ejected from respective nozzles respectively communicating with the respective chambers to the outside of each of the pressure chambers, a cleaning member abutted against a nozzle plate formed with a plurality of nozzles is moved along the nozzles in a state in which pressure is applied to all of the pressure chambers, to thereby extrude foreign particles outside the pressure chambers by the ink ejected from the respective nozzles to the outside of the pressure chambers, thereby making it possible to recover the ink, whereby the occurrence of a delivery failure due to the foreign particles around the nozzles being absorbed into the pressure chambers, can be prevented, and the foreign particles contained in the ink can be purged without consuming much ink needlessly.

Abstract: An ink jet head cleaning apparatus is provided which includes a wiping unit which performs a wiping operation for a nozzle surface of an ink jet head and a suction unit which performs a sucking operation for the nozzle surface. An operation OFF condition of the wiping unit and an operation OFF condition of the suction unit is detected, and the wiping unit and the suction unit are actuated selectively in accordance with the operation OFF condition thus detected. If an elapsed time after the wiping operation is longer than a first predetermined time, the wiping unit is actuated, and if an elapsed time after the sucking operation is longer than a second predetermined time, the suction unit is actuated. The first predetermined time is longer than the second predetermined time.

Abstract: A mechanism is provided for allowing a wipe member formed of an elastic material to abut against a nozzle plate in which a plurality nozzles communicating with a pressure chamber for holding ink therein are arranged, moving the wipe member along the nozzle plate to remove ink and foreign particles remaining in the nozzle plate, and switching the position of abutment of the wipe member against the nozzle plate, whereby satisfactory sweeping capability of the wipe member can be maintained without providing a wipe member cleaning mechanism and performing the work of replacing of the wipe member with another.

Abstract: In an ink jet head cleaning apparatus according to the present invention there are provided a wiping unit which performs a wiping operation for a nozzle surface of an ink jet head and a suction unit which performs a sucking operation for the nozzle surface, and an operation OFF condition of the ink jet head, the wiping unit or the suction unit is detected, then the wiping unit and the suction unit are actuated selectively in accordance with the operation OFF condition thus detected. With this construction, the operation frequency of the suction unit necessary for keeping the nozzle surface of the ink jet head in good condition can be kept low and hence it is possible to reduce the consumption of energy. Besides, it is possible to diminish the operation frequency of the wiping unit which causes wear or damage of the nozzle surface and it is possible to attain a long life of the ink jet head.

Abstract: A reaction vessel used for a genetic test has at least one reaction liquid containing section for containing a reaction liquid. The reaction liquid containing section has an upper well opening in an upper surface of the reaction vessel, a lower well located under the upper well, and a flow path communicating an external space with the lower well. The reaction vessel further has a reaction section disposed between the upper well and the lower well. The reaction section has a nucleic acid probe fixed to bones of a porous member. The upper well opening in the upper surface of the reaction vessel enables optical observation of the reaction section from above the reaction vessel.

Abstract: An ink jet head cleaning apparatus of the present invention comprises a flexible contact member and a driving unit. The flexible contact member is mounted in a position where its top end comes into contact with a nozzle face of an ink jet head having the nozzle face provided with outlets for discharging ink in a form of droplets, and is movable along the nozzle face. On the other hand, the driving unit functions to correlatively move the ink jet head and the contact member. The top end of the contact member is divided into a plurality of sections in a direction orthogonal to the direction of its movement. Thus, a foreign substance holding on the nozzle face can be removed completely from the nozzle face by means of the wipe blade. Furthermore, the growth of the foreign substance can be restrained. It is therefore possible to prevent deterioration of ink discharge stability and straight discharge of ink.

Abstract: A multi-color ribbon cassette position adjusting apparatus comprises a carrier having a print head, a cassette mounting member rockably supported on the carrier, and a fine adjustment mechanism attached to the cassette mounting member, for finely rocking the mounting member. The fine adjustment mechanism includes a guide member fixed to the cassette mounting member, a follower piece guided by the guide member to engage a helical cam for shifting the position of the cassette mounting member, and a position adjusting member for relatively moving the guide member and the follower piece.

Abstract: In a ribbon position selecting device for a printer which includes a step motor for driving a ribbon base retaining a ribbon cassette to locate a ribbon at a predetermined position, the present invention comprises a stopper for determining a reference position of the ribbon cassette, and a power transmitting mechanism for transmitting power of the step motor to the ribbon base. The power transmitting mechanism comprises a torque limiter and a one-way clutch. When the ribbon cassette is brought into abutment against the stopper, the step motor is rotated without step out owing to the torque limiter to prevent deviation in phase at the stop position. In contrast, when the ribbon cassette is driven to separate from the stopper, slipping in the power transmitting mechanism is eliminated by the one-way clutch to secure feeding of the ribbon cassette, thereby eliminating the possibility of mixing of colors.

Abstract: A positioning device for a printer for driving a ribbon base on which a ribbon cassette is carried by means of a stepping motor to position a ribbon to any of predetermined shift positions. The device includes a stopper for defining a home position of the ribbon cassette, and a power transmitting mechanism for transmitting a power of the stepping motor to the ribbon base. The power transmitting mechanism includes therein a torque limiter which yields a slip therein when a torque lower than a pull-out torque of the stepping motor is applied thereto. Accordingly, when the ribbon cassette is abutted with the stopper, the stepping motor is allowed to continue rotation thereof without stepping out by the torque limiter, thereby preventing an out-of-phase condition of the stepping motor at a stopped position thereof. Consequently, upon subsequent operation, the ribbon cassette can be shifted accurately, and hence color mixture in printing can be eliminated.

Abstract: In this invention, the rear ends of the printing needles are bent and prevented from being pulled out by being embedded in needle caps. The needle caps are flat, and the longitudinal directions of the cross-sections of the needle caps are coincident with the radial direction of the printer. The rear ends of the needles are arranged in annular form. Each needle cap is slidably held by a guide body. Lateral displacement of the needles is prevented, and the contacting area between the needle caps and an armature of an electromagnet is reduced. A ring connecting the rear ends of the needles is reduced in size, providing a margin at both sides of the needle cap and armature. The bending amount of the needle is reduced, and the sliding resistance of the needle is reduced, which improves the durability of the needles and the needle guides. Also a small armature may be used, thereby saving on the consumption of power in that an electromagnet of small capacity may be used.
