Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recording device for removing foams and dissolved gas in ink which generate non-jetting of ink or unstabilized jetting without wasting ink and not transferring the foams and dissolved gas in ink into an ink jet head, and also provide a color filter manufacturing device in which the ink jet recording device is used. SOLUTION: Ink in a main tank 301a is fed into a sub-tank 401a by a main pump 302. The ink in the tank 401a is passed through a tube 451, a flowmeter 456, a main deaeration device 511a, a dissolved oxygen meter 520 and the like and fed into sections of three-way valves 502, 504 and 505. The ink fed therein is further fed in the direction of an ink jet head 120a at the time of jetting the ink by the operation of the three-way valves 502, 504 and 505, and returned to the sub-tank 401a through tubes 452, 453 and 454 when the dissolved oxygen amount in the ink is too much.

Abstract: PURPOSE:To improve connection between a display member and an operation member and to attain the linear movement of the operation member by connecting the operation member to the end part of the display part and linearly sliding the operation member on the display member along the display member. CONSTITUTION:A guide groove 19d is formed on the slide member 19 in the width direction and the slide member 19 is engaged and held with/by a frame 25 so as to be stably and linearly moved between a side end part 19e and one face 19d1 of the guide groove 19d in the sliding direction. The position of the slide member projected part 19f is determined so that the projected part 19f presses a change-over switch 18 on a switch board 28 when the slide member 19 is moved in the (b) direction. A switch 18 is switched to two sides by operating the slide member 19. When the slide switch member 19 is moved in the (a) or (b) direction, a slide sheet 21 is moved in the (a) or (b) direction in a recessed part 1a.

Abstract: PURPOSE:To improve the reliability of an operational panel device and to reduce the cost by fixing a key switch substrate unit, to which a plate member movably holding key tops of key switches is fixed, to a housing cover. CONSTITUTION:A switch substrate 2 on which tact switches 9 and the other switch main bodies are mounted and a key switch substrate unit consisting of key tops 8, the other key tops, and a cover metal plate 3 are constituted. The key switch substrate unit is attached to the inside of a housing cover 1 to constitute the operation panel device. That is, bosses 19 of the housing cover 1 are inserted to holes 3c of the cover metal plate 3 to clamp the switch substrate 2 to bosses 19 by screws 18. In this case, key tops 8 and the other key tops are inserted to holes 1a formed in the housing cover 1. Consequently, the switch substrate 2 can be built in the housing cover 1 together with key tops. Thus, the operation panel device is easily assembled and the cost is reduced.

Abstract: PURPOSE:To utilize an ISDN network effectively and to attain efficient communication by executing the communication according to the communication procedure, and storing a received data when a connecting communication terminal equipment is busy and cannot receive a new incoming call. CONSTITUTION:When a call setting command is received from an ISDN network 8 via a line control section 5, a CPU 4 proceeds the processing from an incoming call wait state in the step S1 to the step S2, and sends an incoming command to a G4 FAX 7 connecting to the CPU 4 via a channel interface section 2. When a restoration request command is received from the G4 FAX 7, it ts regarded that the G4 FAX 7 rejects an incoming signal because of the busy state, a connection command is sent to the ISDN network 8, the communication is proceeded to the opposite G4 FAX 7 according to the communication protocol and the picture data received from a B channel is stored in a buffer area of a RAM 6. When the G4 FAX 7 is in the idle state, the stored picture data is read and sent to the G4 FAX 7.

Abstract: PURPOSE:To call an original sender's attention to the courteous write of a character by affecting the judged result of a character recognition rate on a service charge by providing a charge setting means. CONSTITUTION:A character recognition part 12 is provided with a character recognition rate judging function and informs a recognition judged result to a charging part 14. The charging part 14 is comprised in such a way that a charge is decreased if the recognition rate is high and it is increased if the recognition rate is low based on the recognition judged result from the character recognition part 12. When the recognition of all characters in a reception image are completed, the charge is calculated by the recognition rate, and also, the numerical rating of a recognized character is performed by collating with an answer. A result is returned to facsimile 21. In such a way, it is possible to process the character recognition with a fair charging system, and to call a user's attention to the courteous description of the character.

Abstract: PROBLEM TO BE SOLVED: To prevent discharge instability by supplying deaerated ink to a head and to control the change in an ink concentration by the removal of water in the ink during deaeration. SOLUTION: In deaerators 511, 321 for removing dissolved gas in ink by reducing the pressure of a space confronting the ink through a gas permeable membrane equal to or less than the atmospheric pressure, when the pressure is equal to or below the saturated water vapor pressure of water, the amount of water which passed through the membrane per unit time is made 0.5 ml/hr or below, desirably 0.2 ml/hr or below, more desirably 0.04 ml/hr or below. The deaerators 511, 321 are installed in an ink supply route between ink tanks 301, 401 and an ink-jet head 120. When the deaerators 511, 321 are provided in the ink supply route, the amount of water which passed through the upstream deaerator 321 is made greater than that of the downstream deaerator 511.
