  FIG. 5 is a perspective view showing details of the carriage 153 showing characteristic portions of the present invention, and FIG. 6 is a plan view thereof. The carriage 153 includes a mounting portion 31 on which the recording head 152 and the like are mounted, a coupling portion 32 coupled to the belt 156, a coupling means 33 that couples the mounting portion 31 and the coupling portion 32, and the like. The mounting portion 31 has a hole 31a that exposes the nozzle forming surface of the recording head 152 on the bottom surface. The recording head 152 is mounted in accordance with the hole 31a, and a damper or the like is mounted thereon. It has become. The coupling portion 32 is formed with a clamping portion 32a that sandwiches the belt 156 on the back surface, and the clamping portion 32a and the belt 156 are coupled to each other.

  The connecting means 33 includes a leaf spring that is one of linear elastic members 33A formed in a substantially C shape, and is attached to the coupling portion 32 so that a pair of free end portions 33a protrude. The pair of free end portions 33a is attached to the mounting portion 31 by a pair of screws 33b oriented in the main scanning direction. Therefore, in the connecting means 33, the mounting portion 33d of the mounting portion 31 is swingable in the main scanning direction with respect to the mounting portion 33c of the coupling portion 32.

Here, consider a case where a forced vibration P ₀ cosωt expressed by the following equation (1) generated by cogging of the carriage motor or the like acts on the carriage 153. P ₀ is the magnitude of the forced vibration, ω is the frequency of the forced vibration, t is the time, m is the mass of the mounting portion 31 of the carriage 153, a is the acceleration when the carriage 153 is moved, and k is the connection means 33. The spring constant, x, is the displacement of the connecting means 33.
P ₀ cos ωt = ma + kx (1)
In this case, by setting the natural frequency p = √ (k / m) of the mounting portion 31 of the carriage 153 to be away from the frequency ω of the forced vibration, for example, ω / p = 2 or more, The forced vibration P ₀ cos ωt generated by cogging of the carriage motor is absorbed by the connecting means 33, so that propagation to the mounting portion 31 of the carriage 153 can be prevented (see FIG. 7). Therefore, the recording head 152 mounted on the mounting portion 31 of the carriage 153 is not affected by the forced vibration P ₀ cos ωt generated by the cogging of the carriage motor and the like, so that a favorable recording result can be obtained. When the frequency ratio ω / p is increased (p is decreased), the connection becomes too weak and it becomes difficult to control the carriage movement. According to experiments, it was suitable to set the value of ω / p to 2-6.

  As shown in FIG. 7B, a damping element can be added to the connection. In this case, adding in series is more effective than adding in parallel (FIGS. 7B and 2). Specifically, for example, a guide member configured to obtain damping by pressing against the carriage shaft 155 which is a fixed member by urging a spring or the like to the guide portion of the carriage 153 can be realized. is there.

In the above-described embodiment, a leaf spring is used as the linear elastic member 33A of the connecting means 33. However, there is no particular limitation as long as the relationship between the load and the displacement has a linear characteristic. For example, a coil spring is used. Produces the same effect. In this case, one end of a pair of coil springs arranged in series with the displacement direction facing the main scanning direction is attached to both sides of the coupling portion 32, and the other end of the pair of coil springs is attached to the mounting portion. . That is, it arrange | positions so that the coupling | bond part 32 may be pinched | interposed with a pair of coil spring. As a result, the mounting portion 31 can swing in the main scanning direction with respect to the coupling portion 32, so that the forced vibration P ₀ cosωt generated by cogging of the carriage motor can be absorbed by the connecting means 33.

Has been. These regulating members 33B are mounted on the mounting portion 31 with a predetermined gap, for example, several tens of μm, from the mounting portion 33d of the mounting portion 31 in a stationary state. As a result, the large deflection of the linear elastic member 33A generated during acceleration / deceleration of the carriage 153, that is, the delay of the carriage 153 can be regulated by the physical regulating member 33B, and the position controllability of the carriage 153 can be improved. .

  In the embodiment described above, the regulating member 33B (pin) is a separate member, but may be formed integrally with the mounting portion 31. In addition, the regulating member 33B (pin) is arranged on both outer sides of the mounting portion 33d of the mounting portion 31 and in the vicinity of the mounting portion 33c of the coupling portion 32, but both inner sides of the mounting portion 33d of the mounting portion 31. Even so, the same effect is achieved. Moreover, you may make it arrange | position between the attaching part 33c of the coupling | bond part 32, and the free end part 33a. Thereby, when the linear elastic member 33A (plate spring) contacts the regulating member 33B (pin), it is possible to prevent a sudden change in the displacement of the linear elastic member 33A (plate spring) as in the above embodiment.

  As described above, according to the carriage 153 of this embodiment, the mounting portion 31 of the recording head 152 and the coupling portion 32 of the belt 156 are divided, and the mounting portion 31 and the coupling portion 32 include the linear elastic member 33A. Since it is connected by the connecting means 33, the vibration from the belt 156 is cut off at the divided portion and is not transmitted to the mounting portion 31 of the recording head 152, and the recording accuracy of the recording head 152 can be maintained in a highly accurate state. it can.

  Further, since the connecting means 33 has the restricting member 33B for restricting the displacement of the linear elastic member 33A, the large deflection of the linear elastic member 33A that occurs when the carriage 153 is accelerated or decelerated can be restricted by the restricting member 33B. Further, since the gap is provided between the linear elastic member 33A and the regulating member 33B, a small deflection of the linear elastic member 33A that occurs when the carriage 153 is at a constant speed can be absorbed in the gap.

  Any recording apparatus provided with a carriage can be applied to, for example, a facsimile apparatus, a copying apparatus, and the like. In addition to a recording apparatus, the meaning of a liquid ejecting apparatus that ejects a liquid corresponding to its use from a liquid ejecting head onto an ejected medium instead of ink and attaches the liquid to the ejected medium is, for example, a liquid crystal display or the like Color material jet head used for manufacturing color filters, electrode material (conductive paste) jet head used for electrode formation for organic EL display and surface emitting display (FED), bio-organic jet head used for biochip manufacturing, precision pipette The present invention can also be applied to an apparatus equipped with a sample ejection head or the like.
