Accordingly, it is enabled to change over between selection of the type and printing, and it can be contrived to reduce the size and weight of the printer. USE:Pocketable electronic calculators.

Description

[Detailed Description of the Invention] A serial type printing bag machine that uninventively moves the active 7 members in the digit direction to perform printing.V, %, 1st and wA2 outputs can be output alternately! It has a mechanism that alternately turns off the 11th w42 output! ! The present invention relates to a small printing device that can be used for pocket calculators, etc., which selects and prints characters.

1st. A conventional example of controlling iso-folding and printing by using an M-motion mechanism as a conversion mechanism capable of outputting the second output alternately is reported in JP-A-51-112617. *; bv In this g-, in addition to the cut-off box for the cut-out λ of the difference a mechanism, a positioning element is used to maintain the selected character r'L1 during the printing operation. Tei/b,
For this reason, the number of parts is large, the mounting is complicated and large, and since a positioning element is used, the energization of the cutting electromagnet is activated by the cam, and the position is not determined by the cam. There is a need to maintain power until the element power is activated, making it difficult to control energization and consuming a lot of power.

The invention is to eliminate such drawbacks, and its purpose is to maintain the locking part of the selection mechanism that switches the output of variable*mm in a bistable state. The aim is to simplify and reduce the number of parts required to make the installation fl11 smaller and lighter, and to reduce power consumption by shortening the energization to the electromagnet.

An embodiment of the invention will be explained in detail using figures.

The J-carriage 3 has a configuration ζn based on the above accumulated costs.

Next, a series of operations will be explained in detail.

fll This is the initial setting. Initial settings are performed before starting printing.

The engagement between the cam 57b of the print carry cam 57 and the positioning plate 41 is released by the method described later. (Fig. 10 double chain -), one end is mounted on 54f of the carriage frame 54, the other end is supported on the frame 5 on a fixed foot 58, the p direction is changed by a spring guide roller 59, and the p direction is changed. The return spring 63 which urges the carriage 3 in the direction opposite to the arrow H causes the carriage 5t to move in the direction opposite to the arrow H and fix the 54g portion of the carriage frame 54 to the frame 5b.

Rotate and decelerate - AA, planetary gear 10 f arrow K -
Turn L51oJK1g1. At this time, the printing switching cam 11
Since it is locked by the pawl 12aK, the internal gear 11a rotates and revolves around the sun wheel 8C on its own axis, rotating the i4 selection drive gear 9 in the direction of the arrow through the planetary shaft 9a. The selection drive--90 rotations rotates the selection-table 21 fully counter-arrow C times, causing the electromagnetic clutch joint f28, type shaft 22, and type holder 55 to rotate once. A detector 67 consisting of a brush 67 fixed to the type shaft 22 and attached to the type shaft 22 and a brush 67 fixed to the frame generates a type position ejection signal corresponding to the type 50a when desired type is selected. This is done by energizing the coil 29 seven times using the printed position signal. The desired type is mounted on the frame 5as5b.
Coil 2 a little before facing the platen 44? I'm familiar with it. When the coil 29 is energized, the tri-force &27 is absorbed by the electric 6 clutch yoke 28 and rotates together with the electric 6 clutch yoke 28. When the trigger plate 27 starts rotating, the trigger lever 23, which is locked by the pin 25c, also rotates at the same time as the deletion mark c73, against the spring force of the trigger lever spring 25. Rotation i of the trigger lever 25 25 The selection claw 12 is moved by the arrow B
The claw 12cf is rotated in the direction to engage the teeth of the selection claw 42tb to stop the rotation of the selection claw JiL21b (Figure 82, chain-). When the selection claw Ji 21 b is locked, commuting to school-2
2. The rotation of the type holder 53 is also stopped, and the desired type 50a is stopped on the opposite surface of the platen 44, completing the selection (FIG. 6).

(3) When the first digit is printed and the digit 1 trigger lever 23 is rotated, the selection pawl 12 rotates in the direction of arrow B to select the desired type, and at the same time the pawl tZa and the notch 11b are engaged and the n printing is switched. The cam can rotate 110 times freely. At this time, since the rotation of the selection pawl mold 21b is stopped by the pawl 12c, the rotation of the selection tooth I21 and the residual drive 1 tooth base 9 is also stopped.

Therefore, when the planetary secret is rotated 100 times, the inner 1118 city 11a block print inspection cam 11 is rotated in the direction of arrow P. Mark 7 The rotation mark of the switching cam 11 rotates the hand gear 15, the print 114, and the print carry cam 57. When the print carry cam 57 rotates, the cam lead of the end cam 57a causes the limiter spring 61 and the transmission lever 6017 to be rotated. mark the hammer 55 as missing ■

0, the type belt 50 is protruded from the inside 91, and the type 50a is transferred to the platen AA via the printing boat 45.
Press K to print (Figure 6 = chain line A). At this time, due to variations in the autopsy door, etc., the hammer 55a 55a and the platen 44
Even if the distance from the printing type 50a changes, is the suppressing force of the printing type 50a -? The limiter lock 616 operates so that. Furthermore, the variation in the stop position of the printing type 50a in the rotation direction is caused by the difference in the stop position of the hammer 55, 55c,
55a and 53bT of the type halter 53: The alignment of the corrected and printed characters in the line direction is discontinuous and has little variation. Ink is applied to the surface of the printed characters 50a using an ink roll # (not shown) using a well-known method.

Since the coil 29 is de-energized and the trigger lever 27 is free to rotate, the trigger lever 23 rotates in the same direction as the arrow C7j due to the action of the trigger lever spring 250 and returns to the standby state (see Fig. 2). As soon as the printing gear 15 starts rotating, the return lever 1S is moved in the missing marking direction by the NYT end cam 15a provided on the printing gear 15.
