The ideal embodiment of the present invention will be described in detail with reference to the drawings. The first and second figures show the printer of the present invention. The third to fifth figures show the printers installed in the first and second figures. Spring device on the printer. As shown in Figure 1, the printer P of this embodiment is configured as a dot impact printer, and the basic structure of the spring device A installed on the printer p is removed. It is almost the same as the printer described in the conventional technology. Specifically, the printer P includes a printing unit 1, a counter balancer 2, a linear motor 3, a pair of auxiliary members 4, and a pair of spring meals. Device a. The printing unit 1 is generally called a hammer table, and as shown in FIG. 2, it has an appropriate amount of dot impact type printing heads 10 as printing hammers. A platen roller 70 is provided at a position facing the print head 10, and the recording paper κ is configured to be conveyed therebetween. As shown in FIG. 1, a pair of guide portions 11 are provided on both ends of the printing unit 1 in the longitudinal direction, and the guide portions 丨 are externally fitted on the guide shaft 6 extending in the horizontal direction and are slidable. Of the state. A pair of auxiliary members 4 is intended to be positioned between one of the pair of guide portions 11 of the printing unit 丨 and fitted on the guide shaft 6 in a slidable state. If the spring device A is to be located between each auxiliary member 4 and each guide portion n, it is installed on the guide shaft 6 ------------- · I --- 111 ^ ------ 11 (Please read the precautions on the back before filling this page) This paper size is applicable to China National Standard (CNS) A4 specification (2) 0297 mm) -11-515756 A7 B7 printed by the Consumer Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the invention (11) The first sleeve 51 of A is in a state of tightly binding the guide shaft 6 with a certain elastic force, and can slide in the long direction of the guide shaft 6 due to a large force. With this, the position of the spring device A can be easily determined. When the linear motor 3 is driven and the printing unit 1 is moved to the right in the figure, the guide portion 11 at the left end of the printing unit 1 and the corresponding auxiliary member 4 will approach each other. Thereby, at both ends of the spring device A located therebetween, the guide portion 11 and the auxiliary member 4 will contact each other, and the spring device a is pressed from both sides in the direction of arrow N1 in FIG. 3. As described above, each of the second sleeves 52 of the spring device a slides toward the center of the length of the first sleeve 51 while compressing the spring 53. At this time, the resistance of the spring will become an auxiliary force for decelerating the printing unit 1, and the burden on the linear motor 3 when decelerating the printing unit 丨 near the end will be reduced. When the guide portion 11 and the auxiliary member 4 are in contact with the spring device A ', they are intended to be in contact with the cushioning material 54 having less elasticity than each of the second sleeves 52, thereby reducing the conflict at that time and controlling the generation of noise. When the printing unit 1 reaches the right end of the reciprocating area, the spring device A will be in the state shown in Fig. 5. Then, when the printing unit 1 is reversed, the guide portion 11 and the auxiliary member 4 move in opposite directions. In addition, the pair of second sleeves 52 are intended to slide the sides of both ends of the first sleeve 51 by the elastic force F of the spring 53 and to impart potential energy to the guide portion n and the auxiliary member 4 in the direction in which they move. . This potential energy will become an auxiliary force for accelerating the printing unit 1, and the burden on the linear motor 3 when the printing unit is reversed and accelerated will be reduced. When the distance between the guide portion n and the auxiliary member 4 becomes larger, the spring device A will return to the state shown in FIG. 3. When the printing unit 1 moves to the left in FIG. 1 and reverses, it is held in the spring device between the guide 11 on the right end of the printing unit 1 and the corresponding auxiliary member 4 to fit the paper to the iV standard.

Description of the invention (12 The same effect as above can be obtained. In the compression action and response action of the above-mentioned spring device A, The second sleeve 52 slides against the first sleeve 51 while expanding and contracting the spring 53. For this reason, the first sleeve 51 will not move. As a result, the spring device a will become a guide portion 11 and an auxiliary member. If the spring device A is displaced from the center portion, any one of the guide portion 11 and the auxiliary member 4 will conflict with one end of the spring device A prior to the other, and press the spring device a to another One side, and the phenomenon that the entire spring device is unstable to reciprocate on the guide shaft 6 will occur, but in this aspect To prevent such a situation, each of the second sleeves 52 is loosely fitted to the guide shaft 6 and the first sleeve 51, respectively, so that it is difficult to cause loss of these parts. It is also assumed that the loss of the guide shaft 6 causes the A slight change in the surface state, or a larger diameter of the guide shaft 6 due to temperature rise, can also prevent the friction force of each second sleeve 52 from moving sharply in the long direction of the guide shaft 6. When the spring device A is compressed by the guide portion π and the auxiliary member 4 when the second sleeve 52 is compressed, and when the spring device A is returned from the compressed state to the original non-compressed state, the second sleeve is provided with the guide portion.丨 丨 and the force of the auxiliary member 4 will be stabilized ', and all the reciprocating actions including the acceleration and deceleration of the printing unit 1 will be stabilized.
