本発明はシリアルプリンタに関し、特にシリアルプリン
タの低消費電化に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a serial printer, and particularly to reducing power consumption of a serial printer.
従来のこの種のプリンタを図面を参照して説明する。 A conventional printer of this type will be explained with reference to the drawings.

方向へ加速するように制御する。FIG. 2 shows an example of the configuration of a conventional printer. The step motor l pulls the wire 2 and moves it parallel to the left and right along the Rad carriage guide 4. As a result, serial printing is performed while the print head 5 is moved horizontally over the printing paper 6. K to reverse the moving direction of the head carriage
The motor is controlled by changing the excitation pulse width of the motor to decelerate, stop, or accelerate in the reverse direction.

テップモータを反転方向へ加速している区間である。The power consumed by the motor at this time will be explained using a diagram. In FIG. 3, the vertical axis represents the amount of electric power consumed by the motor, and the horizontal axis represents the passage of time. A constant velocity area 11 is an area where the print head is moving at a constant speed, a deceleration area 12 is an area where deceleration braking is applied to the print head, and a stop area 13 is an area where stop braking is applied to the print head to completely stop it. The section, the reverse acceleration region 14, is a section in which the step motor is accelerated in the reverse direction in order to advance the Herad carriage in the reverse direction.

動作域で大きな電力を必要とする欠点がある。The conventional serial printer described above uses a drive motor to operate in a sequence of deceleration, stop, and acceleration in order to return the head carrier and print, so it has the disadvantage of requiring a large amount of power in the low-speed operating range. .

の励磁を開始する。FIG. 1 is a block diagram of an embodiment of the present invention. The head carriage 7 constitutes a linear motor with the panel 8, and prints while moving right (left) K relative to the printing paper 6. When the head carriage 7 passes the right (left) edge of the printing paper, it is detected by the sensor 9 and the excitation to the motor is stopped. The head carriage 7 hits an elastic repulsion mechanism 10 attached to the right (left) end of the middle carriage guide 4 and is decelerated by a Kuban.
At that time, due to the force exerted by the spring, the Yaridia in the head eventually changed its direction of movement to the left (right). The sensor 9 detects that the direction of movement has changed and starts excitation of the motor in the left (right) direction.

ラドキャリッジを加速する区間である。The power consumed by the motor at this time will be explained using a diagram. In FIG. 4, the vertical axis P represents the amount of electric power consumed by the motor, and the horizontal axis T represents the passage of time. A constant velocity region 11 is a region in which the print head is moving at a constant velocity, a non-excitation region 15 is a region in which the motor is not energized, and a reverse acceleration region 14 is a region in which the Herad carriage whose traveling direction is changed is accelerated.
