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.

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.
摘要:
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.

The electric apparatus performs time display that is optimal for a user, without need of operations for switching time display by use of the 12-hour system and 24-hor system. In a tape printer, a keyboard section and a CPU are connected to each other via any one of a plurality of solder points A, B, and C. If the solder point is “A” (YES at S103), an hour system flag is set to “OFF” (S105). If the solder point is not “A” (NO at S103), the hour system flag is set to “ON” (S107). If the hour system flag is OFF, a target country (target district) of the keyboard section is “USA”, so that time is displayed in the 12-hour system on a liquid crystal display section, while if the hour system flag is ON, the target country (target district) of the keyboard section is not “USA”, so that time is displayed in the 24-hour system on the liquid crystal display section.

A biorelated substance examination apparatus includes a reaction stage which supports a reaction vessel which contains the solid support and promotes a reaction of the solid-state phase, and a microscope which optically observes the solid support. The reaction stage includes a fluid transfer mechanism which transfers a fluid with respect to the reaction vessel and a temperature adjusting mechanism which adjusts a temperature of the solid support in the reaction vessel.

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.

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.

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.

In a printing apparatus, the number of delimiters included in received data from a host apparatus is smaller than the number of input items of a template by one. Therefore, the number of delimiters included in the received data from the host apparatus is calculated to be three. A character string which is periodically repeated in the received data three times as the number of the delimiters is obtained and set to be a delimiter candidate. Further, a print start character string candidate is obtained from a data group which is located after a last delimiter candidate in the received data. Using the provisionally determined candidates for a delimiter and a print start character string, the four item data included in the received data are assumed. Then, a print preview is displayed on a LCD so as to show a state where the four item data is input to each of the input items of the template.
