Abstract

PURPOSE:To enable to perform stamping on a bunch of multiple sheets of paper and on a single sheet of paper at the same stamping pressure, by a method wherein a disk is pushed up by an upper end part of a link, and a type wheel is moved upward by a compression spring through an arm. CONSTITUTION:In the case of stamping by a type wheel at point A, the disks 13, 13 of the arms 7, 7 are stopped at point P1. In the case of stamping by the type wheel 8 at a point B, the disks 13, 13 of the arms 7, 7 are stopped at a point P2. Both when the type wheel 8 is stopped at point P1 and when it is stopped at point P2, the links 6, 6 are moved downward while escaping rightward from the outside peripheries of the disks 13, 13. The extending ratio of the compression springs 16, 16 intermediately provided between the links 6, 6 and the arms 7, 7 is the same at point Q1 and at point Q2 of the arm fitting part, so that the force exerted when the links 6, 6 escape from the disks 13, 13 is the same at point P1 and at point P2. Accordingly, if the force of the springs 16, 16 is assumed to be the stamping pressure, the stamping pressures at positions between P1 and P2 are the same.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in electric numbering machines.

In conventional electric numbering machines, when stamping multiple sheets of paper one on top of the other, the letter wheel starts from point O and moves between O-A or O- as shown in Figure 1. When moving up and down between B and attempting to stamp at any position between A and B, it has not been possible to technically solve the problem that the printing pressure changes between the upper and lower positions.

The reason for this is that the conventional technology used a method of absorbing the difference between the large ships above and below through the elastic body of the spring.
The printing pressure changed depending on the amount of deflection of the spring, which caused a difference in the amount of ink applied between A and B, resulting in poor printing conditions.

Therefore, the present invention aims to eliminate the technical drawbacks of the conventional machines, and provides an electric numbering machine that can stamp both a large stack of paper and a single piece of paper with the same printing pressure. The purpose is to

The structure and operation of the present invention will be explained with reference to the embodiments shown in the drawings.

First, the electric circuit and its operational relationship will be explained with reference to FIGS. 2 and 3.

(S 1) (S 2) (S 3) (S 4) (
S 5) (S 6) are both switches, (Sl)
is a power switch, and (S2) is a changeover switch. (1) is a solenoid, and (2) is a motor.

Now, after turning on the power switch (Sl), turn on the changeover switch (S2) that leads to the foot switch (S3) or paper contact switch (s4). When this changeover switch (s2) is connected to the paper contact switch (S4) side, insert the stack of paper or piece of paper (a) placed on the machine stand 04) to the back.

The rear end portion contacts the paper stand switch (S4).

Then, the solenoid (1) is activated, the cam operation switch (S5J is turned on, the motor (2) is started, and the cam (31 (3) installed on the left and right sides of the body is rotated through the transmission mechanism described later). When this cam (31+31 switch (S5) button falls into the home position recess t41+41 on the cam surface, both switches (S5) (S) are turned off and the motor (2) stops. S3)
The transmission relationships of (S4), (S5), and (S6) are indicated by arrows in FIG. 3 until the motor stops.

Furthermore, in FIG. 4, the relationship between the cam switch (S5), the home position switch (86), and the motor (2) is shown with reference to the states of each switch in FIG. Figure 3 ■ @ motor starting state Figure 1 (b)

However, the mounting position of the letter ring can be freely changed vertically or horizontally. The hanging plate (20) is always held in a horizontal position, but if you want to correct the condition of the letter ring (8), simply rotate this hanging plate (20+ diagonally upward).

By the way, the operation of the related mechanism including the character wheel (8) will be explained in more detail as follows.

First, in Fig. 1, when the character ring (8) is stamped at point A, the arm +71 +71 disk (131 (+3+ is p,
Stop at a point. 1. When the character ring (8) is stamped at point B, the arm disk 031031 stops at point 22. Character wheel (
8) stops at point P and when it stops at point 22, the ring fil (61 descends while escaping to the right around the outer circumference of the disk (131 (13).The force in both cases is The relationship is between the link +61 +61 and the arm (91 of the arm attachment part of the contractile bomb c(6) interposed between the link +61 and the arm (71).
Since the expansion rate of the bullet is the same at point and point 92, the force when link +61 +61 escapes from disk α31 (131) is Pt = Pz. Therefore, the bullet ・θ,
If the force of 61 (16) is the printing pressure, the printing pressure between Pt and PZ is the same. (For the above, refer to Fig. 6) As the link (61 (61) disengages from the disc (13103) and further descends, the bullet -α0 is extended and the printing pressure tends to gradually increase.However, this The trend is link (61 (6
