Description

[Detailed Description of the Invention] This invention relates to a marking device such as a printer used to stamp a plurality of marks on recording paper.

For example, in order to stamp two product names on a label in a label printer, etc., a holder that was conventionally held in a vertically movable manner is fixed between the two product names, and the two product names are stamped with one movement of the holder. However, if there is even a slight variation in the height between the product names, the stamped surfaces between the two product names will not match, resulting in a lack of sharpness in the stamped state and a difference in shading.

This invention was devised in view of these points, and is intended to provide a marking device such as a printer that can clearly print a plurality of marks with uniform density.

This idea connects a holder that holds another mark B to an actuating body that holds mark A so that it can move relatively freely, moves the actuating body toward the recording paper, and brings mark B into contact with the recording paper. When the actuating body is moved and the mark A comes into contact with the recording paper, the mark B appears.
is elastically retracted together with the holder to keep the mark A and the mark B in contact with the recording paper in the same plane, and therefore,
The structure is such that even if there are variations in the size of the mark, it can be clearly stamped with uniform density.

An embodiment of this invention will be described based on the drawings.

Reference numeral 1 denotes an actuating body that is connected to a drive unit (not shown) such as a solenoid and reciprocates in a direction opposite to the label 2, which is recording paper.

A part A3 marked A is detachably attached to the actuating body 1.

Next, a holder 5 is provided to detachably hold the other mark B, B4.

This holder 5 has a shaft 6 projecting upward, and the middle part of this shaft 6 is held movably up and down by a cylindrical guide 7 fixed to the actuating body 1, and the upper part of the shaft 6 is attached to the actuating body 1. It is held by a fixed guide plate 8 so as to be vertically movable.

This guide plate 8 is formed with a long hole 10 for holding a spring pin 9 press-fitted into the upper part of the shaft 6 so as to be movable up and down, and for preventing the shaft 6 from rotating together with the holder 5.

Further, a retaining ring 11 is fixed to the shaft 6, and a compression spring 12 is provided between the retaining ring 11 and the guide plate 8'.
By interposing the shaft 6 with the holder 5, the shaft 6 is urged downward.

. The upper surface of the guide 7 is a stopper 13 that is joined to the retaining ring 11 to determine the stopping position of the holder 5.

In this state, the stamping surface 15 of B4 in the product name has a dimension h greater than the stamping surface 14 of B4 in the product name on the label 2.
protrude to the side.

In such a configuration, when the operating body 1 is lowered, B4 in the product name comes into contact with the label 2, and when the operating body 1 is further lowered, A3 in the product name contacts the label 2.

At this time, the holder 5 and the product number 4 are retracted upward relative to the actuating body 1 as shown in FIG.
．． 15 is maintained in contact with the label 2 in the same plane.

Therefore, even if there is a size difference between A in the product name and B4 in the product name, the two product names are uniformly stamped with uniform darkness.

The holder 5 has one shaft 6 held by a guide 7,
Since the elongated hole 10 is fitted into the spring pin 9, rotation is prevented by a simple structure and the spring pin 9 is held movable up and down.

Therefore, B4 in the product name does not shift in the plane direction with respect to the label 2.

Since this device is constructed as described above, when stamping, the mark B comes into contact with the recording paper first, and when the mark A comes into contact with the recording paper, the mark B is elastically retracted to the plane that coincides with the mark A. Therefore, it has the effect of making it possible to clearly print a plurality of marks with uniform density.

Claims (1)

[Scope of utility model registration request] An actuating body to which a mark A to be stamped on the recording paper is attached is provided so as to be able to reciprocate in a direction opposite to the recording paper, a holder to which another mark B is attached is provided, and the holder is attached to the actuating body so as to face the recording paper side. The actuating body is provided with a stopper that is attached so as to be able to move forward and backward while being biased, and that determines a stop position of the holder at a position where the stamping surface of the middle B projects toward the recording paper side from the stamping surface of the middle A.
