Description

DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application The present invention relates to an inkjet recording device, and in particular, it is capable of achieving monochrome and color copies at low cost.

b. Prior Art A typical conventional inkjet recording apparatus is one in which ink contained in an ejection nozzle is ejected using a piezoelectric element or the like.

c Problems to be Solved by the Present Invention In the conventional configuration as described above, a large number of nozzles are provided, but since the entire nozzle is not constantly moistened with ink, it may dry out and clog the nozzle. This occurred and appeared as white spots when printed, which was extremely inconvenient.

d Means for Solving the Problems The present invention aims to provide extremely suitable means for eliminating the above-mentioned drawbacks. a head body, a tape drive reel provided on the head body, a tape wound around the drive reel and movable, a large number of microholes or microrecesses formed in the tape, and a tape drive reel provided on the head body; This means includes a thermal head for folding and guiding the tape, and an ink cassette provided in the head body and detachably provided between the thermal head and the drive reel.

(e) Effect The ink in the ink cassette is stored in the micropores or microrecesses of the tape that is slid and moved by the drive reel, and the ink is ejected by the heat generated by the thermal head.

f Example Hereinafter, an inkjet type recording apparatus according to the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a color inkjet type recording device according to the present invention, in which a head body 2 is slidably attached to a pair of guide rods 1, 1 provided on a main body (not shown) in the direction of arrow A. On this head body 2, four tape cassette bodies 3 are removably arranged in parallel, and as shown in FIGS. It contains a tape 5 wound around a reel 4. As shown in FIGS. 4 and 5, this tape 5 is formed with a large number of micropores 6 or microrecesses (not shown) for storing ink, and is made of polyimide or metal foil with high heat resistance. ing.

Each tape reel 4 of this tape cassette body 3 is removably provided with respective shafts 7a, 8a of drive gears 7, 8 provided on the main body (not shown), and a guide gear tape 9 provided on the main body (not shown). . A pair of V-shaped guide pieces 12 are provided in the opening 3a of the tape 5, and a tape 5 is guided outside of the guide pieces 12, and is set in a thermal head 13 provided at one end of the head body 2. In this case, position the tape 5 outside the thermal head 13 and pull the tape cassette 3 toward you as shown by the arrow in Fig. 2.
The tape 5 is locked to the thermal head 13 and the setting is completed.

An ink cassette 14 is detachably provided between the thermal head 13 of the head body 2 and the tape cassette body 3, and supplies ink into the micropores 6 of the tape 5.
4 is constructed as shown in FIGS. 6 to 8, and a box-shaped case 15 has an engaging piece 16 of the head body 2.
An ink tank 18 containing ink 17 is formed at the bottom of the box-shaped case, and a pair of ink-impregnated bodies 19 made of string-like felt or the like are immersed in the ink tank 18.
is held by the side holding part 20 of the box-shaped case 15.

A pair of holes 22 are formed in the base 21 of the box-shaped case 15, and the legs 24 of the tape bonding body 23 to be bonded to the ink-impregnated body 19 are attached and removed with play as shown in the figure. In addition to being freely inserted, the periphery of this base portion 21 is surrounded by a surrounding portion 25 to prevent excess ink from leaking to the outside, and an ink absorber 26 is provided at the joint portion of this base portion 21. has been done. Further, the upper end of the box-shaped case 15 is formed with an extension part 15a from the end of the ink-impregnated body 19, so that it can be grasped without getting your hands dirty.

Furthermore, a cap body 28 having a pressure contact spring 27 for bringing the tape bonded body 23 into pressure contact with the ink-impregnated body 19 is detachably provided on the top of the box-shaped case 15. That is, FIG. 7 shows a state in which the cap body 28 is removed, and FIG. 8 shows a state in which the cap body 28 is attached. moreover,
FIG. 9 is a cross-sectional plan view of FIG. 8, showing a state in which the tape 5 is clamped.

10 and 11 show a switching mechanism for moving the head body 2 in either the left or right direction. When the switching body 29 of the head body 2 is switched in the direction of arrow B, either drive gear 7, 8 meshes with one of the gear tapes 9, 10, and each drive gear 7, 8 rotates in the same direction, so the head body 2 can move in any left or right direction.

When printing with the above configuration,
Each ink cassette 14 has 4 colors of Y, M, C, and BLK.
Since there are available colors, color copies can be made by reciprocating the head body 2 from side to side and rotating the recording paper 31 wound around the platen 30. Incidentally, it is also extremely easy to perform monochrome printing with one color.

g. Effects of the invention Since the invention has the above structure and function,
The tape with micropores containing ink is constantly rotating and sliding, which prevents the ink from drying out, allowing for excellent printing without clogging, and making it extremely easy to use ink cassettes and tape cassettes. Since it can be replaced, maintenance is also extremely easy.
