[Problems to be solved by the device]

 However, in such a mounting structure of the printing device 4, since the tightening force of the screw 9 and the load of the entire printing device 4 are applied to the rubber member 7, if the rubber member 7 is formed of a material having high elasticity, it is crushed. , The printing device 4 cannot be supported well. For this reason, it is necessary to form the rubber member 7 with a material having high rigidity. However, if the rubber member 7 is formed with a material having high rigidity, the vibration of the printing device 4 cannot be reliably absorbed, and the vibration of the printing device 4 will not occur. There is a problem that it becomes easier to reach.

The cause is that one rubber member 7 has a function of absorbing the vibration of the printing device 4 and a function of restricting the position of the printing device 4, and the rubber member 7 is formed of a material having high rigidity. caused by.

If the elastic member is made of a material having high elasticity by separately receiving the function of absorbing the vibration and the function of restricting the position by separate elastic members, the printing device 4 will be described. Can be favorably supported and vibration of the printing apparatus can be reliably absorbed.

An object of the present invention is to enable the elastic member to be formed of a highly elastic material by separately providing the elastic member with the function of absorbing vibration and the function of restricting the position. Is.

【Example】

 Hereinafter, examples will be described with reference to FIGS. 1 to 4. The same parts as those in FIGS. 5 and 6 are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

As shown in FIGS. 1 and 2, a cylindrical case 20 having a closed bottom is provided in the lower case 2 in correspondence with the four corners of the lower surface of the printer 4. A coil spring (elastic support member) 21 elastically supporting the lower surface of the printing device 4 to elastically support the printing device 4 is provided in the vane storage portion 20 so as to project upward.

On the other hand, leg portions (fixed portions) 5 provided with notches 6 are provided at the four lower corners of the printing device 4, respectively. Of these legs 5, the first elastic position restricting member 22 is attached to the two legs 5 on the front side (the left side in FIG. 2) and the two legs 5 on the rear side (the right side). The second elastic position regulating member 23 is attached.

The first elastic position restricting member 22 is made of a highly elastic material such as rubber and has a recess 24 formed on one side surface thereof into which the notch 6 of the leg 5 is loosely fitted from the side. In addition, an insertion hole 26 through which the screw 25 is inserted is provided so as to vertically pass therethrough. The screw 25 is inserted into the insertion hole 26 through the notch 6 of the leg portion 5 which is loosely fitted in the recess 24 of the first elastic position restricting member 22, and the lower end portion thereof has a recessed shape provided in the lower case 2. It is screwed into the screw hole 28. Therefore, the position of the first elastic position restricting member 22 in the horizontal direction is restricted by the screw 25, and the upper limit position is restricted by the head of the screw 25.

The second elastic position restricting member 23 is made of a highly elastic material such as rubber, and has a notch 30 into which the notch 6 of the leg 5 is fitted in the middle in the thickness direction thereof. At the same time, the restriction projection 31 is provided on the outer end portion so as to project upward. The second elastic position restricting member 23 is inserted laterally into the box-shaped restricting portion 32 provided in the lower case 2 and elastically contacts the inner wall of the restricting portion 32 so that the second elastic position restricting member 23 moves backward. The position is regulated, and the regulation projection 31 is engaged in the engagement groove 33 provided in the upper portion of the regulation portion 32 so as to be vertically movable, whereby the position in the left-right direction and the upper limit position are regulated.

In such a mounting structure of the printing device 4, the printing device 4 is elastically supported by the coil spring 21, and the position of the printing device 4 is restricted by the first and second elastic position restricting members 22 and 23. Thus, the function of absorbing the vibration of the printer 4 and the function of regulating the position of the printer 4 can be separately provided by the coil spring 21 and the elastic position regulating members 22, 23. Therefore, it is not necessary to form the coil spring 21 and the elastic position restricting members 22 and 23 with a material having high rigidity as in the prior art, and a material having high elasticity can be used, so that the printing device 4 is favorably supported. In addition, the vibration of the printing device 4 can be reliably absorbed so as not to be transmitted to the lower case 2.

The present invention is not limited to the above-described embodiment, and may be configured as shown in FIG. 4, for example. That is, the bottom portion of the cylindrical spring accommodating portion 20 provided in the lower case 2 is opened and vertically penetrated, and the screw hole 28 is vertically penetrated, and a metal shield plate is formed on the lower surface of the lower case 2. The coil spring 21 and the screw 25 may be brought into contact with the shield plate 40, respectively. By doing so, not only the vibration generated in the printing device 4 but also the static electricity generated in the printing device 4 can be grounded, and the adverse effect of the static electricity generated in the printing device 4 can be prevented.

Further, although the above-described embodiment has been described in the case of being applied to an electronic register, the present invention is not limited to this, and can be widely applied to other information processing devices such as a word processor.

[Effect of the device]

 As described above, according to this invention, the position of the printing device is elastically restricted by the elastic position restricting member, and the printing device is elastically supported by the elastic supporting member, so that the position of the printing device is restricted. The elastic position regulating member and the elastic supporting member can be separately provided with the function of performing the vibration and the function of absorbing the vibration, and thus it is necessary to form the elastic position regulating member and the elastic supporting member with a material having high rigidity. Instead, it can be formed of a highly elastic material, and as a result, the printing device can be favorably supported, and vibration during printing can be reliably absorbed so as not to be transmitted to the device case.
