Abstract

PURPOSE:To enable to smoothly lift up a ribbon cassette without generating any reaction, by pressing a lift for a ribbon base by a cam operated by a clapper- type magnet. CONSTITUTION:An attracting force of an armature 16 by the clapper-type magnet 17 for driving a driving lever 13 is small at first since the gap G at the attracting part is somewhat large, but the attracting force F is rapidly increased as the gap G is reduced. When an initial attracting force F of the armature 16 is small, the cam 9 is turned slowly. When the attracting force F is increased in proportion to the reduction of the gap G, a cam-driving roller 12 passes over a projected surface 9c to reach a curved surface 9b, which is a lifting position and is so shaped that the roller 12 becomes stable thereon. Engagement between the lever 13 and the cam 9 is relieved of contact friction by the roller 12. Accordingly, the lift for the ribbon base 6 can be stably raised without receiving any strong shock.

Conventional technology In general, ink ribbons used in printers, electronic typewriters, etc. are stored in a ribbon cassette, and when printing in two colors, for example black and red, the ink ribbon is divided into two in the width direction. It is colored. For color separation during printing, a ribbon cassette set in the printing mechanism is moved in a direction in which the ink ribbon side is moved up and down to select the color of the ribbon facing the printing position.

However, conventional ribbon cassette switching movements were performed using plunger-type magnets, which caused a reaction when the ribbon stopped at the switching position when switching up and down, making it difficult to switch instantly to support high-speed printing. There was a problem in that it was difficult to shorten the operation. On the other hand, the plunger type magnet requires a bearing to support the plunger, and since these parts wear out relatively quickly, there is a problem that unstable operation of the ribbon lift mechanism is more likely to occur.

The drive lever (13) has an armature (16) on the arm portion (], 3a), and this armature faces the clapper-type magnet 1-(47). The magnet (17) is fixed to the play 4 (15) and attracts the "-2 armature (16) when supplied with operating current.

In the above, the cam (9) has a first curved surface (9
a) and a second curved surface (9b), and a protrusion (9c) is provided at the contact point of both concave surfaces. In this case, the clapper-type magnet 1-(17) that drives the drive lever (13)
As shown in Fig. 5, the suction force (F) of the armature (16) is small due to the gap (G) of the suction part of the scissor being slightly wider.
As this gap (G) narrows, the suction force (F) increases rapidly, and since the so-called suction force (F) has a curved relationship, the first curved surface that the cam drive roller (13-2) comes into contact with. (9a) has a gently curved surface. Therefore, when the initial suction force (F) of the armature (16) is small, the cam (9) is designed to rotate slowly.

Next, as the gap (G) decreases, the suction force (F) increases, and when this suction force (F) becomes strong, the cam drive roller (12) passes the protrusion (9c) and reaches the lift position. The position of the second curved surface (9b) is reached, and this second curved surface (9b
) This second curved surface (9b) is configured so that the cam drive roller (12) is stabilized at the position. In addition, the drive lever (1
3) and the cam (9), the contact friction is alleviated by the cam driving roller (12). Therefore, the ribbon support platform (6) can be lifted stably without being subjected to strong impact. In addition, the lowering of the ribbon holder stand (6) is as follows:
Spring (1) due to de-excitation of magnet 1-(17)
The elastic bias of 8) and the ribbon holder are performed using the weight of the table (6).

On the other hand, as for the mechanism for lifting the ribbon holder (6), only the set on the front side (left side of the carriage) is shown in the illustration, but this can be used as needed for the carry 5-.
-114- The same mechanism as described above may also be arranged on the right side of the edge (1). In addition, the ribbon holder has a claw (
6a) serves to hold the ribbon force set I-(5), and (5a) shows the ink ribbon led out to the printing area. Therefore, although shown in the drawing, the printing mechanism mounted on the carriage (1) is located at the position of the ink ribbon (5a) that has been led out.

Therefore, when printing with red ink on the printing surface, when making corrections using the collection ribbon, or when moving the ink ribbon from the printing position to check the printing condition, the ink ribbon is The lift is strongly subjected to impact vibrations caused by the lift and causes amplitude movements, which can cause problems such as loss of vibration stop time during lift and loosening of the ink ribbon. It can be done without any problems. For this reason,
According to the present invention, such troubles can be solved and the stability of operation of the printer during high-speed printing can be greatly improved.
