Cassette for liquid jet recording and liquid jet recorder

[Detailed Description of the Invention]

The technical field to which an invention belongs The invention of this application makes a subject the cassette for fluid injection record, liquid jet recorder VC, and the account and Recording device with Si and more sufficient operativity than easy composition that are related. Conventional technology The recording ink exchange in liquid jet recorders, such as an ink-jet recording device, is recording ink (it may be called ink below.). If it cassettes and the ink of the specified quantity is exhausted, Mostly will exchange the whole cassette. Therefore, it is although the residual volume detection means for telling a user about the residue of ink is required and the means of the conventional various kinds is proposed, In the latest color liquid jet recorder, since the quantity of Ahupsilon and the ink of each color moreover used differs in the necessity of using the ink of a plurality of colors, it will be necessary to form a residual volume detection means about the ink of all the colors, and the fault of complicating the recorder itself will be produced. then -- although the recording form on which the user was recorded is investigated, without forming a residual volume detection means, consumption of ink is judged and the device which carries out ink exchange by this is proposed -- a means desirable for a user -- Then. (deterioration of the quality of record is not avoided.) The object of an invention Therefore, an object of the 1st invention of this application is to record all the recording forms in a cassette and to provide the usage Freshly cassette for fluid injection record which is discharged and which it comes and was exchanged for a new cassette. The necessity of carrying out separately Yo Si, ' charge of a recording form, and exchange of recording ink to using the cassette in the 1st invention the 2nd invention (it aims at providing a liquid jet recorder with very sufficient operativity.), Constitution of an invention Both inventions of the 1st of this application are characterized by the cassette for fluid injection record (cassette 1 which contains recording form storage 1a and ink tank part 1b of Drawing 2 in the below-mentioned example, for example) in which a recording form and recording ink are stored. The 2nd invention, A means to combine removably the cassette in which both a body part (similarly the main part A of a recorder of 1 figure),; recording form, and recording ink are stored, the; above-mentioned cassette, and the above-mentioned body part (a liquid jet recorder provided with; is carried out to it being the same (supply tube 11 provided with hollow needlelike object 26 of Drawing 2) with the feature.) In the above, quotation of the below-mentioned example does not limit the scope of the invention of this application at all, and the invention of this application can change that operative condition A * suitably into the statement of the above-mentioned claim. If the embodiment of the 1st invention is further explained, a cut sheet will be used as a recording form, Recording ink of the specified quantity corresponding to the number of sheets of the recording form of the number of predetermined leaves, and this recording form in one cassette, for example, the recording ink of the minimum quantity required to record the recording form of the above-mentioned number of sheets is stored -- if all the recording forms in upsilon and a cassette are recorded and discharged, the usage Freshly cassette in which the recording form exchanged for a new cassette and recording ink were unified will be started. The embodiment of the cassette in the 2nd invention is the same as the above. the whole example composition of the liquid jet recorder applied to the invention of this application with reference to drawings below -- and similarly it explains to details in order of the example of the cassette for fluid injection record. The whole example figure 1 of composition (Drawing 1) of the liquid jet recorder concerning the invention of this application shows the whole example composition of the liquid jet recorder concerning the invention of this application, and the figure shows the state where the cassette was inserted in the recorder. In the opening of a country, the cassette for which the main part of a recorder is stored as for A, and a recording form and ink are stored 1 is shown, and it is assumed in this example that a recording form is stored in upper part 1a, and ink is stored in lower ink tank part 1b. The detailed composition of recovery set 1 is mentioned below with reference to Drawing 2. mouth ~ in which 2 feeds with one sheet of recording form at a time from cassette 1 -- Stroke -- it is discharged out of a vessel through between the 2nd pinch roller 6 and platen 60, recording form PA which exists and with which it was fed from feed low 22 passing along between platen 3 and the 1st pinch lows 24, and being guided by guide plate 5. Pinch rollers 4 and 6 are welded by pressure to platen Filtration by publicly known structures, such as an example Eve spring mechanism, and 10 which recording form PA sticks to the platen second completely is a head unit, and is opening them for free passage with ink tank part 1b in cassette 1 ^ Via a supply tube. Nozzle 13 contracts to an inner direction publicly known, and head unit 10 makes an ink droplet breathe out by impressing pulse voltage to After Si and piezoelectric vibrator 14 to composition with ink liquid-storage room hollow cylindrical piezoelectric vibrator 14. Whenever one drop of ink is breathed out, ink is supplied to liquid-storage room 10a by capillarity from the main tank (20 of Drawing 2) in cassette 1. Drawing 2 of an example (Drawing 2) of the cassette for fluid injection record concerning the invention of this application shows the detailed structure of cassette 1, and the joint structure of the main tank 20 in that ink tank part 1b, and a main part, and 20 in a figure is stored in Ah Si and ink tank part 1b by the flexible main tank. be a tube, and the one end should stick with the main tank 20, and should be combined with one, and the other end should be press-fitted to rubber bush 22 inserted in the outer frame of cassette 1, and boil 21 -- it has prevented Sike flowing into the exterior. Hollow needlelike object 26 like metal hypodermic needles is connected at the tip of supply tube 11 prolonged from head unit 10 on the other hand, and it is being fixed to main part A. Since the structure in recording form storage 1a is publicly known, explanation is omitted. In the above-mentioned composition, if cassette 1 is put in main part A of a recorder in the figure Nakaya seal direction and it is crowded, hollow needlelike object 26 will penetrate rubber bush 22, and will be inserted into tube 21, and the ink supply route from the main tank 20 will be completed. If all the recording forms stored in cassette 1 are used, cassette 1 will be exchanged for a new cassette without, Si, and if needed from the main part people of a recorder. EFFECT OF THE INVENTION As explained to details above, a recording form and recording ink are stored in a cassette for fluid injection record in both inventions of the 1st of this application. Therefore, if all recording forms in a cassette are recorded and discharged, a usage Freshly cassette exchanged for a new cassette can be provided. In the 2nd invention, a cassette in the 1st invention was removably combined with a main part of a recorder. Therefore, the necessity of performing charge of a recording form and exchange of recording ink separately (a recording ink residual volume detection means is also unnecessary, its operativity of a liquid jet recorder improves remarkably, and composition of a device is simplified.),

[Brief Description of the Drawings]
