Abstract

PURPOSE:To form a grain shielder, which can shield ink grains excellently without hardly generating ink mists, by shielding each ink grain having the different quantities of deflection by separate inclined plane in an ink jet recording device. CONSTITUTION:When ink is ejected from a nozzle 3, to which a piezoelectric element 2 is fitted, in a device 1 conducting recording by grains such as non- electrostatic rectilinear propagating small-diameter grains, small-diameter grains 5a and large-diameter grains 5b are separated alternately and flown. When a recording signal input X represents a command through which recording dots are not formed, large charge signal voltage is applied, and the quantities of deflection of small-diameter grains take flying paths larger than the quantities of deflection of large-diameter grains, and reach to a grain shielder 11. With the grain shielder 11 with an inclined plane 12, an inclined plane section A mainly shielding large-diameter grains and large and small coalescing grains is formed to an upper section, and an inclined plane section B mainly shielding small- diameter grains is shaped on the side where the quantities of deflection are larger than the inclined plane section A. Accordingly, the shielder 11 does not generate mists, thus resulting in no fouling of deflection electrodes 9 and recording paper 10 by mists.

ている。Recently, in this type of apparatus, a new recording apparatus that dramatically improves the accuracy of the adhesion position of particles to recording paper has been studied. In this newly considered recording device, if the recording signal is a command to cause Izik particles to adhere to the recording paper to form recording dots, large-diameter particles, small-diameter particles, or both will be ejected according to the engraving signal. Then, without being charged or deflected, the ink is allowed to travel almost straight in the direction of ink ejection from the nozzle, and is deposited on the recording paper to form recording dots. If the recording signal is a command to prevent ink particles from adhering to the recording paper and forming recording dots, both the large diameter particles and the small diameter particles are charged and deflected from the ink ejection direction of the nozzle to the front of the recording paper. A particle shield installed at
(large and small diameter coalesced particles) to prevent them from reaching the recording paper.

のでなくてはならない。Incidentally, since small-diameter particles have a much greater deflection sensitivity than large-diameter particles, small-diameter particles are deflected to a greater extent. Therefore, the shield must be capable of sufficiently shielding not only large diameter particles and large and small combined particles, but also small diameter particles that are deflected to a large extent.

。However, since conventional shielders are designed to shield ink particles that follow approximately equal trajectories, when applied to the above-mentioned recording device, either large-diameter particles, combined large- and small-diameter particles, or small-diameter particles are It was possible to shield well, but it was not possible to shield both well. For example, large-diameter particles and large- and small-diameter combined particles can be well shielded, but small-diameter particles do not collide with the shield at appropriate positions, and when they collide, they generate ink mist, which charges the particles and deflects them. There were problems in that it adhered to the electrodes for recording, causing equipment failure, and it adhered to the recording paper, contaminating it.

電信号電圧を印加しインク粒子への帯電量を制御する。When pressurized ink is guided to a nozzle 3 equipped with a piezoelectric element 2 that is excited by a high frequency power source 1 and ejected, the ejected ink becomes an ink column 4, but after that, the surface tension of the ink Due to the effect, the ink particles separate into particles and fly away. At this time, by setting particle creation conditions such as excitation intensity and ink supply pressure to appropriate values, ink particles with a small diameter (small diameter particles) 5a and ink particles with a large diameter (large diameter particles) can be created. 5b alternately separates from the ink column 4 and begins to fly. The recording apparatus shown in FIG. 1 records only with small diameter particles among these generated particles. A charging electrode 6 is disposed near the tip of the ink column 4, and a particle charging signal voltage from a particle charging signal generating device 7 is applied to this electrode to control the amount of charge on the ink particles.

る。Recording signal to the particle charge signal generation device 7 When the manual command X causes ink particles to adhere to the recording paper and form a recording dot, the preceding ink particles are A charging signal voltage is applied that takes the charging state into consideration. These uncharged small-diameter particles fly in the electrostatic field formed between the deflection electrodes 9a and 9b by applying a voltage from the high voltage power source 8, but because they are uncharged, they are hardly deflected. The ink travels almost straight in the direction of ink ejection from the nozzle and collides with the recording paper 10, forming a recording dot. On the other hand, if the recording signal force X is a command not to form recording dots, a larger charging signal voltage than in the previous case is applied, and the ink particles are charged and deflected according to the size of the particles. The deflection sensitivity of ink particles is considerably larger for small-diameter particles than for large-diameter particles or large- and small-diameter combined particles, so as shown in the figure, the amount of deflection of small-diameter particles is larger than that of large-diameter particles. , the particle interceptor 11 is reached by taking a different flight path. The light is then shielded without reaching the recording paper.

This inclined surface is deflected as described above and has a length sufficient to receive all of the nine-diameter particles, large- and small-diameter combined particles, and small-diameter particles. Then, there is a first sloped surface section on the upper part close to the flight trajectory of the particles that form the recording dots, which mainly shields large-diameter particles and large- and small-diameter combined particles. Since there is a second inclined surface part B that mainly shields, the shielder 11 can shield not only large-diameter particles but also small-diameter particles without generating mist. Without further ado, record paper 1

することができる。According to this shield 11, compared to the embodiment shown in FIG.
Since the dimension of the particle shield 11 in the particle flight direction can be shortened, the distance from the electrode 9 to the recording paper 1o can be shortened. Therefore, the flight distance of the particles forming the recording dots can be shortened, and the particles can be accurately attached to the target position on the recording paper 100. This is because by shortening the particle flight distance, it is possible to reduce the disturbance of particle flight trajectories due to the influence of air and interference between particles. Therefore, it is possible to set an appropriate angle at which mist is less likely to be generated, depending on the incident angle of the particles colliding with each inclined surface and the particle size.

The surfaces of the inclined surface portion B, which mainly shields the ink particles A, are arranged so that the surfaces on which the respective ink particles collide face each other. The inclination angles of the respective inclined surfaces 12A' and 12B' are set to appropriate angles. This shield has the advantage of the embodiment of FIG. 2 over the embodiment of FIG. There is no problem of mist being generated due to collision with the ink particles, and even if the amount of deflection of the small-diameter particles varies slightly, the ink particles can be shielded without generating mist.

In this case, although the amount of deflection of the small-diameter particles 5a varies slightly depending on the charging state of the preceding large-diameter particles 5b, in this embodiment, the ink can be well shielded and collected without generating almost any ink mist.
