Abstract

PURPOSE:To enable a paper to be inserted extremely easily, by a method wherein a free lever is separated from a platen together with bail rollers when inserting a paper, and when the free lever is further deviated, an exclusive-use switch for paper feeding is turned ON to rotate the platen. CONSTITUTION:When inserting a paper 27, a free lever 13 is turned by a handle 25 in the direction for moving away from the platen 2, and the paper 27 is inserted between the platen 2 and a paper pan 4 through a port 5. When a toggle spring 18 is deformed beyond a neutral point, a leaf spring 22 supports the lever 13 substantially at a neutral point, thereby preventing a switching part 23 from making contact with an actuator 20. When the lever 13 is further turned against the spring 22, the switching part 23 turns ON the exclusive-use switch 21 for paper feeding to rotate the platen 2, so that the paper 27 is inserted between the platen 2 and a paper guide 26 by the platen 2 and pinch rollers 9. Thereafter, the operating force exerted on the lever 13 is released to return the lever 13 to the neutral position, and then the lever 13 is tilted to the platen side to press the bail rollers 16 against the platen 2.

When the operating force is removed, the plate returns to the near neutral position shown in Figure 2 due to the force of the lever and releases the actuator lever, but in this example, the force of the paper feed switch Q is The driving time of the motor is determined by a timer by the switching operation, and the paper (b) is fed a fixed length regardless of the time the actuator fA is pressed. Of course, the timer is omitted and the time when the actuator is pressed is the platen (2

Furthermore, as shown in Fig. 2, the free lever 〇 is supported by a leaf spring holder at an intermediate position against the force of the toggle spring.
Although the paper feed switch Q force was kept OFF, the force that urges the actuator (A) upward was made larger than the force of the toggle spring α, and this actuator (A) was used instead of the leaf spring (2). It may also be used as a support part. Alternatively, a supporting portion may be used to apply lateral pressure to the free lever (to) at an intermediate position, and the free lever (to) may be stopped at the intermediate position by this lateral pressure.

Effects of the Invention Since the present invention is configured as described above, when inserting paper, the presser roller is released from the platen together with the 7-leave lever, but from this state, by further releasing the free lever from the platen, the platen is driven and the paper is pulled out. It has the effect of being easy to insert.
